    Full Text Available Mucinous carcinoma (MC (colloid carcinoma is a particular, rare type of breast carcinoma. It is characterized by the presence of extracellular mucin. MC of the breast generally presents as a lobulated, moderately well-circumscribed mass on mammography, sonography, and magnetic resonance imaging. It has a favorable prognosis due to the low incidence of axillary lymph node metastasis and poor adherence to bottom fascia and poor infiltration of overlying skin. It has high incidence of estrogen receptor and progesterone receptor positivity. The incidence of MC in females under 35 years of age is only 1%. Here, we report a case of MC of right breast in a 30-year-old female.

    Full Text Available Abstract Background Poorly differentiated midline carcinoma with a translocation between chromosomes 15 and 19, i.e. t(15;19, has been recognized as a distinct clinical entity for over a decade. This tumor affects young individuals, shows a rapidly fatal clinical course despite intensive therapy. The t(15;19 results in the fusion oncogene BRD4-NUT. Information concerning treatment of this rare disorder is scarce. Case presentation A 30-year-old woman was admitted with a rapidly progressing tumor in the mediastinum, cervical lymph nodes, vertebral column and the epidural space. Pathological, cytogenetic, FISH and PCR analysis revealed a glycogenated carcinoma rarely expressing cytokeratins and showing t(15;19 and BRD4-NUT gene rearrangement. The patient was initially treated with a Ewing sarcoma chemotherapy regimen, but had rapid progression after two cycles. She then received docetaxel and radiotherapy, which resulted in almost complete disappearance of the tumor. Conclusion Docetaxel may be considered for initial chemotherapy in young patients presenting with a midline carcinoma with bone marrow involvement and cytogenetic and molecular genetic finding of a t(15;19/BRD4-NUT-rearrangement. We herein describe, in detail, the laboratory methods by which the BRD4-NUT -rearrangement can be detected.

    Full Text Available Purpose. To report a case of unilateral optic neuritis following Measles-Mumps-Rubella (MMR vaccination. Methods. A 30-year-old female developed unilateral optic neuritis five days after a Measles-Mumps-Rubella (MMR booster vaccination. The patient displayed unilateral involvement, with severe visual loss. However, visual acuity improved significantly after four days of intravenous steroid therapy with 500 mg/day of methylprednisolone. Conclusions. Optic neuritis is one of the rare complications associated with the mumps, measles, and rubella vaccine. It may be a toxic reaction to the nonviral component of the vaccine, but the exact etiology is unknown. Postvaccination neuritis is generally bilateral and usually affects children. In adults, unilateral optic neuritis is usually correlated with multiple sclerosis (MS.

    We compared age-related changes in wrinkles in eight areas of facial skin (forehead, glabella, upper eyelid, corner of the eye, lower eyelid, nasolabial groove, cheek, and corner of the mouth) and sagging in the subzygomatic area of Caucasian females and of Japanese females. The subjects studied included 85 healthy Caucasian females (ages 20-69 years) living in Cincinnati in the U.S. and 70 Japanese females (ages 20-69 years) living in Tokyo. Photos of the face in frontal and in oblique 45 degrees views were analyzed. Wrinkles in the face and sagging in the subzygomatic area were graded on Japanese photoscales, respectively, by the same experienced observer. The wrinkle score increased with age in all eight areas of the face examined in Caucasian females as well as in Japanese females. In the group aged 20-29 years, the wrinkle score in each area was significantly higher in Caucasian females than in Japanese females. The wrinkle scores in the forehead, glabella, upper eyelid, and corner of the eye were similar at advanced ages between the two groups, while the wrinkle scores in lower areas of the face (lower eyelid, nasolabial groove, cheek, and corner of the mouth) were markedly higher in Caucasian females than in Japanese females in each age group, and reached an upper limit at advanced ages in Caucasian females. The sagging score also increased with age in Caucasian females as well as in Japanese females. The sagging score was significantly higher in Caucasian females than in Japanese females in the groups aged 40 years or more. These results suggest more marked wrinkle formation in all areas of the face in younger age groups of Caucasian females living in North America than in Japanese females living in Tokyo. In particular, Caucasian females showed marked age-related wrinkle formation in the lower areas of the face, probably due to sagging in the subzygomatic area, which suggests a higher susceptibility to sagging in the subzygomatic area of Caucasian females.

    Full Text Available Problem statement: Multifocal Skeletal Tuberculosis (MSTB is a rare presentation of skeletal tuberculosis. The indolent nature of this condition often leads to delayed or missed diagnosis, sometimes with devastating consequences for the patient. In order to provide meaningful clinical information and to highlight pitfalls in diagnosis of MFST, we present a case of MSTB. A review of this condition is included for broader coverage. Approach: A 30 year old immune-competent male patient with a 1 year history of indolent soft tissue masses on the chest wall overlying the sternum and the ribs. CAT scan of the chest showed multiple lytic bony lesions involving the ribs, sternum and vertebrae that mimicked metastatic cancer. Fine needle aspiration of the lesion revealed AFB and granulomas. Culture of the aspirated material grew mycobacterium tuberculosis and a diagnosis of MSTB was made. Results: A diagnosis of MSTB was made and anti-tuberculous therapy was initiated. Conclusion: This case indicated that multi-focal skeletal tuberculosis may develop in immune-competent patients without overt pulmonary involvement. From our experience along with previously reported data, MSTB should be suspected in patients from endemic areas who present with multiple skeletal bony lesions. Appropriate management and therapy are essentials for cure and to prevent complications.

    Hepatitis C virus (HCV) infection incidence among 18- to 30-year-olds is increasing and guidelines recommend treatment of active injection drug users to limit transmission. We aimed to : measure linkage to HCV care among 18- to 30-year-olds and identify factors associated with linkage; compare linkage among 18- to 30-year-olds to that of patients >30 years. We used the electronic medical record at an urban safety net hospital to create a retrospective cohort with reactive HCV antibody between 2005 and 2010. We report seroprevalence and demographics of seropositive patients, and used multivariable logistic regression to identify factors associated with linkage to HCV care. We defined linkage as having evidence of HCV RNA testing after reactive antibody. Thirty two thousand four hundred and eighteen individuals were tested, including 8873 between 18 and 30 years. The seropositivity rate among those ages 18-30 was 10%. In multivariate analysis, among those 18-30, diagnosis location (Outpatient vs Inpatient/ED) (OR 1.78, 95% CI 1.28-2.49) and number of visits after diagnosis (OR 5.30, 95% CI 3.91-7.19) were associated with higher odds of linking to care. When we compared linkage in patients ages 18-30 to that among those older than 30, patients in the 18-30 years age group were more likely to link to HCV care than those in the older cohort even when controlling for gender, ethnicity, socioeconomic status, birthplace, diagnosis location and duration of follow-up. Eighteen- to 30-year-olds are more likely to link to HCV care than their older counterparts. During the interferon-free treatment era, there is an opportunity to prevent further HCV transmission in this population.

    ONO-5334, a selective inhibitor of cathepsin K, is a potential new treatment for osteoporosis. The objectives of this study were to (1) develop population pharmacokinetic-pharmacodynamic (PK-PD) models for ONO-5334 using dose-ascending data from healthy postmenopausal females, (2) examine comparability of PK and/or PD profile between Caucasian and Japanese, and (3) compare PK-PD profile between immediate release tablet (IRT) and sustained release tablet (SRT). The population PK-PD models were developed for each formulation for post-dose levels of bone resorption markers (serum CTX and NTX). The data were provided from 4 phase 1 studies with total of 201 Caucasian and 94 Japanese subjects. Plasma concentrations of ONO-5334 and bone resorption markers were thoroughly evaluated in those studies. An indirect response model described relationships between bone resorption markers and plasma concentrations of ONO-5334. There was no significant difference in PK and pharmacodynamic potency (IC50 ) between Caucasian and Japanese. Based on the developed model, serum CTX and NTX after administration of ONO-5334 IRT or SRT were simulated, and the results showed that ONO-5334 SRT would provide comparable PD effect on bone resorption markers with lower dose relative to IRT.

    Full Text Available Acute interstitial nephritis (AIN is a common cause of acute kidney injury and has been associated with a variety of medications. This is the case of 30-year-old man with Hodgkin’s lymphoma who on routine labs before chemotherapy was found to have acute nonoliguric renal failure. A kidney biopsy was performed and confirmed the diagnosis of acute interstitial nephritis. The patient had taken several medications including a higher dose of Carnivora, a Venus flytrap extract, composed of numerous amino acids. The medication was discontinued and kidney function improved towards the patient’s baseline indicating that this may be the possible cause of his AIN. Proximal tubular cell uptake of amino acids increasing transcription of nuclear factor-kappaB is a proposed mechanism of AIN from this compound.

    Full Text Available Introduction: The aim of this study was to determine incidence of cardiovascular disease (CVD risk factors [hypertension (HTN, obesity, Dyslipidemia (DLP, diabetes mellitus (DM and smoking] in Oskoo. Methods: This study was planned according to WHO protocol “WHO CVD-risk management package for low and medium-resource settings” and named “East Azerbaijan healthy heart program”. The pilot study of this program was done in Oskoo in 2007-2009. In this study, demographic data and CVD risk factors of 37,329 adults aged ≥30 years old living in Oskoo were collected. In addition, blood samples of 17,388 adults ≥40 years old were taken (free of charge for assessment of serum glucose and lipid profile. Results: The study covered 93.52% of Oskoo town population aged≥30 years old. We studied 18637 male (91.50% coverage and 18692 female (95.52% coverage participants. The incidence of HTN [SBP≥140 & DBP≥90 mmHg] was 16.25% (M:15.08%, F:17.29%, pre-hypertension [SBP=120-139 & DBP=80-89 mmHg] =37.78% (M:41.38%, F:34.18%, DM [fast blood glucose (FBS≥126mg/dl] was 7.45% (M:6.35%, F:8.54%, smoking was 9.40% (M:17.00%, F:1.57%, hypercholesterolemia (>200mg/dl was 47.64% (M:42.46%, F:52.81% and obesity [body mass index (BMI ≥27] was 50.47% (M:38.79%, F:62.09%. Conclusion: Considering high incidence of CVD risk factors (except smoking in Oskoo adults ≥30 years, it is recommended that this pilot study expanded to all of East Azerbaijan. Free of charge taking blood samples from people ≥ 40 years to evaluate lipid profile and glucose levels is worthy to early detecting the prevalent DM or DLP in this target population.

  17. Autologous Bone-Marrow-Derived-Mononuclear-Cells-Enriched Fat Transplantation in Breast Augmentation: Evaluation of Clinical Outcomes and Aesthetic Results in a 30-Year-Old Female

    Full Text Available Autologous fat transfer (lipofilling is becoming an invaluable tool for breast augmentation as well as for breast reconstruction. Autologous lipofilling has several advantages, including biocompatibility, versatility, natural appearance, and low donor site morbidity. The main limitation is unpredictable fat graft resorption, which ranges from 25% to 80%, probably as a result of ischaemia and lack of neoangiogenesis. To obviate these disadvantages, several studies have searched for new ways of increasing the viability of the transplanted fat tissue. One promising approach is to enrich the fat graft with autologous bone-marrow-derived mononuclear cells (BMMNCs before transplantation. BMMNCs produce many angiogenic and antiapoptotic growth factors, and their secretion is significantly enhanced by hypoxia. All of these mechanisms of actions could be beneficial for the stimulation of angiogenesis in ischemic tissues by BMMNCs administration. In our aesthetic surgery practice, we use fat transplantation enriched with BMMNCs, which caused a significant improvement in survival of fat grafts, compared with that of traditional lipofilling. Our experience with freshly isolated autologous fat enriched with BMMNCs for breast augmentation procedures is presented. The concept of this surgical and tissue handling technique is based on ability of BMMNCs to stimulate blood vessel growth.

    2013-01-01

    Full Text Available Abstract Background Papillary renal cell carcinoma is a rare cancer. Some cases can be attributed to individuals with hereditary renal cell carcinomas usually consisting of the clear cell subtype. In addition, two syndromes with hereditary papillary renal cell carcinoma have been described. One is the hereditary leiomyomatosis and renal cell carcinoma, which is characterized by cutaneous and uterine leiomyomas and renal cell carcinoma mostly consisting of the papillary renal cell carcinoma type II with a worse prognosis. Case presentation We describe a case of a 30-year-old woman with hereditary leiomyomatosis and renal cell carcinoma syndrome with extensively metastasized papillary renal cell carcinoma, primarily diagnosed in a cervical lymph node lacking leiomyomas at any site. Conclusion Papillary renal cell carcinoma in young patients should be further investigated for a hereditary variant like the hereditary leiomyomatosis and renal cell carcinoma even if leiomyomas could not be detected. A detailed histological examination and search for mutations is essential for the survival of patients and relatives.

    2006-07-13

    A collaborative study was conducted in France in order to determine the prevalence of cannabinoids, opiates, cocaine metabolites and amphetamines in blood samples from drivers killed in road accidents in 2003 and 2004 and to compare these values with those of a previous study performed during the period 2000-2001 involving 900 drivers. Blood samples were provided from 2003 under 30-year-old drivers, killed in a traffic accident. Drugs of abuse were determined by gas chromatography-mass spectrometry using the same analytical procedures in all the 12 laboratories. The most frequently observed compounds were by far cannabinoids, that tested positive in 39.6% of the total number of samples. Delta9 tetrahydrocannabinol (THC), the most active of the principle constituents in marijuana (cannabis sativa), was detected in the blood of 28.9% drivers and was the single drug of abuse in 80.2% of the positive cases. It was associated with amphetamines in 7.4% and with opiates and cocaine in 1.9 and 4.8%, respectively. Amphetamines were present in 3.1% of the total number of samples, cocaine metabolites in 3.0% and opiates in 3.5%. When comparing these results with those of a previous study performed 3 years before, a significant increase is observed for THC (28.9% versus 16.9%), cocaine metabolites (3.0% versus 0.2%) and amphetamines (3.1% versus 1.4%). This study demonstrates the critical necessity of implementing in France as soon as possible systematical roadside testing for drugs of abuse.

    Full Text Available Chinese cork oak (Quercus variabilis forests are protected on a large-scale under the Natural Forest Protection (NFP program in China to improve the ecological environment. However, information about carbon (C storage to increase C sequestration and sustainable management is lacking. Biomass, C, nitrogen (N and phosphorus (P storage of trees, shrubs, herb, litter and soil (0–100 cm were determined from destructive tree sampling and plot level investigation in approximately 30-year old Chinese cork oak forests on the south slope of the Qinling Mountains. There was no significant difference in tree components’ biomass estimation, with the exception of roots, among the available allometric equations developed from this study site and other previous study sites. Leaves had the highest C, N and P concentrations among tree components and stems were the major compartments for tree biomass, C, N and P storage. In contrast to finding no difference in N concentrations along the whole soil profile, higher C and P concentrations were observed in the upper 0–10 cm of soil than in the deeper soil layers. The ecosystem C, N, and P storage was 163.76, 18.54 and 2.50 t ha−1, respectively. Soil (0–100 cm contained the largest amount of C, N and P storage, accounting for 61.76%, 92.78% and 99.72% of the total ecosystem, followed by 36.14%, 6.03% and 0.23% for trees, and 2.10%, 1.19% and 0.03% for shrubs, herbs and litter, respectively. The equations accurately estimate ecosystem biomass, and the knowledge of the distribution of C, N and P storage will contribute to increased C sequestration and sustainable management of Chinese cork oak forests under the NFP program.

    Full Text Available During recent years, it has been noticed a remarkable increase in frequency of admission of young individuals in Intensive Care Units (ICU due to road accidents. The aim of the present study was to compare the reasons of admission of young individuals 18-30 years old to young adults 31-40 years old in ICU due to road accident. Method and material: The sample studied consisted of individuals 18-40 years old that were hospitalized in ICU due to road accident. Data were collected by the completion of a specially designed clinical protocol for the needs of the research. For the analysis of data the statistical package SPSS 13 was used and the x2 method. Results: 81,2% of the sample-studied were men and 18,8% women. Regarding nationality, 80,1 % were Greek and 19,9% foreigner. 34,6% of the participants were unemployed, 21,2% were working in private sector, 20,1% were free-lancers and 16,2% students. 46,3% of individuals were admitted in ICU after transfer of another hospital. In 69,7% of the participants age 18-30 years old and 74,5% of 31-40 years old road took place accident at night and 77,3% 18-30 years old and 77,0% of 31-40 years old road accident took place on the way to entertainment. The statistical analysis of data showed that : road accidents were the main reason for admission in ICU of young individuals of age 18-30 years old with statistically significant difference compared to those 31-40 years old, p<0,001. Brain injuries as well as admission of motorcycle drivers were more frequent in individuals of age 18-30 years old with statistically significant difference compared to those 31-40 years old, p=0,018 and p=0,041, respectively. On the contrary, admission of car-drivers and those who had consumed alcohol were more frequent in individuals of age 31-40 years old with statistically significant difference compared to group 18-30 years old, p=0,041 and , p<0,001, respectively. Conclusions: More often admitted in ICU motorcycle drivers of

    Many studies have reported digit ratio (2D:4D) to be sexually dimorphic, (males lower 2D:4D than females). However, Kratochvíl and Flegr ([2009]: Biol Lett 5:643-646) have suggested that 2D regressed on 4D has an allometric regression line with nonzero Y-intercept that is shared by males and females. Thus, 2D is shorter than expected when 4D is long, and males have lower 2D:4D than females because they have longer fingers. In this study, it is shown that this suggestion may be incorrect because sex differences in slope were not considered. Participants were recruited in an Internet study and had an age range of 12-30 years. The expected sex difference in 2D:4D was found, and the regression of 2D on 4D showed a significant sex difference in slope (males lower than females). A comparison of 10 age groups (12 years, 13 years..., 21-30 years) showed that sexual dimorphism for fingers was age dependent, varying from monomorphic to very dimorphic. Changes in sexual dimorphism of 2D:4D were much less marked, but there was a significant reduction in mean 2D:4D with age. The tendency for slopes of 2D regressed on 4D to be lower in males compared with females was significant in eight age groups. Sex difference in 2D:4D varied across the age groups and was positively related to the magnitude of the difference in female and male slopes. In contrast to the report of Kratochvíl and Flegr, it was found that the regression of 2D on 4D showed sex differences in slope, and such differences gave rise to the sexual dimorphism in 2D:4D.

  3. Very Long Segment Congenital Thoracoabdominal Aortic Coarctation (Diffuse Aortic Dysplasia) with Infrarenal Aortobi-Iliac and Cavobi-Iliac Aplasia in a 30-Year-Old Patient.

    Congenital dysplastic aortic syndromes range from coarctation at the aortic isthmus to more extended aortic disease (midaortic syndrome). The latter is usually restricted to dysplastic aortic segments of up to 15 cm. Long segment dysplasia of the entire abdominal or thoracic aorta is extremely rare. This case of a 30-year-old patient with a very long segment congenital thoracoabdominal aortic coarctation and infrarenal aortobi-iliac and cavobi-iliac aplasia represents to our knowledge the most extended congenital vascular malformation in a surviving adult patient. The developed extensive collateral pathways ensured the survival of the patient, so that the main clinical manifestation was a refractory hypertension. Because of the extent of the disease, open surgery represented the only viable option. Interestingly, after 30 years of uncontrollable hypertension, the patient's blood pressure promptly responded to surgical treatment. A concomitant infrarenal aplasia of both the aorta and cava vein is also very unusual and points to a major developmental deficit during vascular embryogenesis.

    Full Text Available Although interposition soft-tissue (biologic resurfacing of the glenoid with humeral hemiarthroplasty has been considered an option for end-stage glenohumeral arthritis, the results of this procedure are highly unsatisfactory in patients less than 40 years old. Achilles tendon allograft is popular for glenoid resurfacing because it can be made robust by folding it. But one reason that the procedure might fail in younger patients is that the graft is not initially thick enough for the young active patient. Most authors report folding the graft only once to achieve two-layer thickness. We report the case of a 30-year-old male who had postarthroscopic glenohumeral chondrolysis that was treated with Achilles tendon allograft resurfacing of the glenoid and humeral hemiarthroplasty. An important aspect of our case is that the tendon was folded so that it was 50–100% thicker than most allograft constructs reported previously. We also used additional measures to enhance allograft resiliency and bone incorporation: (1 multiple nonresorbable sutures to attach the adjacent graft layers, (2 additional resorbable suture anchors and nonresorbable sutures in order to more robustly secure the graft to the glenoid, and (3 delaying postoperative motion and strengthening. However, despite these additional measures, our patient did not have an improved outcome.

    Full Text Available BACKGROUND: High concentrations of pro-inflammatory cytokines have been previously observed in the genital fluids of women enrolled in microbicide trials and may explain observed increased HIV transmission in some of these trials. Although the longitudinal nature of these studies allows within-subject comparisons of post-product levels to baseline levels, the fact that the physiologic variations of these cytokines and other markers of immune activation are not fully defined in different populations, makes it difficult to assess changes that can be directly attributed to microbicide use as opposed to other biological and behavioural factors. METHODS: Cervicovaginal lavage samples were collected from 30 healthy Caucasian and assayed for concentrations of ten cytokines/chemokines, total protein content and two antimicrobial proteins using a multiplex immunoassay and ELISA. Cellular markers were characterized by flow cytometry on mononuclear cells collected from the endocervix using flocked swabs. Bacterial quantification was performed using quantitative PCR. RESULTS: Ectopy, menstrual cycle phase, prostate-specific antigen and presence of leucocytes in endocervical cells' supernatant were associated with the concentrations of cyto-/chemokines in cervicovaginal secretions. Approximately 3% of endocervical cells collected were monocytes of which a median of 52% (SD  = 17 expressed both CD4 and CCR5 markers. Approximately 1% of the total cells were T-cells with a median of 61% (SD  = 10 CD4 and CCR5 expression. Around 5% of the monocytes and 16% of the T-cells expressed the immune activation marker HLA-DR. Higher percentages of T-cells were associated with greater quantities of IL-1RA, GM-CSF and elafin. CONCLUSION: We demonstrate the presence of selected soluble and cellular immune activation markers and identify their predictors in the female genital tract of healthy women. Future clinical trials should consider ectopy, sexual activity

    Computational anthropomorphic human phantoms are useful tools developed for the calculation of absorbed or equivalent dose to radiosensitive organs and tissues of the human body. The problem is, however, that, strictly speaking, the results can be applied only to a person who has the same anatomy as the phantom, while for a person with different body mass and/or standing height the data could be wrong. In order to improve this situation for many areas in radiological protection, this study developed 18 anthropometric standing adult human phantoms, nine models per gender, as a function of the 10th, 50th and 90th mass and height percentiles of Caucasian populations. The anthropometric target parameters for body mass, standing height and other body measures were extracted from PeopleSize, a well-known software package used in the area of ergonomics. The phantoms were developed based on the assumption of a constant body-mass index for a given mass percentile and for different heights. For a given height, increase or decrease of body mass was considered to reflect mainly the change of subcutaneous adipose tissue mass, i.e. that organ masses were not changed. Organ mass scaling as a function of height was based on information extracted from autopsy data. The methods used here were compared with those used in other studies, anatomically as well as dosimetrically. For external exposure, the results show that equivalent dose decreases with increasing body mass for organs and tissues located below the subcutaneous adipose tissue layer, such as liver, colon, stomach, etc, while for organs located at the surface, such as breasts, testes and skin, the equivalent dose increases or remains constant with increasing body mass due to weak attenuation and more scatter radiation caused by the increasing adipose tissue mass. Changes of standing height have little influence on the equivalent dose to organs and tissues from external exposure. Specific absorbed fractions (SAFs) have also

    A 20-year old patient who had been adequately treated for lymph node tuberculosis 14 years ago presented 1 week after giving birth to a healthy daughter. She complained about painful lumps in both axillae. During pregnancy the patient suffered from hyperemesis gravidarum, lost 6 kg of weight, and had night sweats. During the last three months of her pregnancy she had a deep vein thrombosis in her right lower leg. The clinical examination showed soft axillary lumps up to 3 cm. The lab showed the following pathological findings: blood sedimentation rate 51 mm/h, CRP 44.8 mg/l, LDH 221 U/l and INR 1.3 (indicating insufficient anticoagulation with phenprocoumon). The chest x-ray showed no infiltrate or indications of a past tuberculosis. A fine needle aspiration cytology was performed on an accessible node. Gram stain, Ziehl Neelsen stain, as well as the bacteriological cultures were all negative. An ultrasound examination of the axilla showed a thickened subcutis without a mass. Cytology showed lobular epithelium, consistent wih ductal mamma epithelium without atypical cells. The diagnosis of an accessory mamma tissue in both axillae was made. During the course of the following weeks the glands decreased in size and the patient was free of symptoms.

    Full Text Available Bilateral finger and palm prints of 500 males and 500 females of the Caucasian origin in South Iran have been collected and analyzed for both qualitative and quantitative dermatoglyhic features. Results show that most of the qualitative features on bilateral and bisexual differences are not significant. However, quantitative features frequently showed significant differences both bilaterally and bisexually. These results, when, compared with some Indian groups revealed insignificant differences in qualitative dermatoglyphics, while, the quantitative features frequently showed significant differences. The importance of quantitative dermatoglyphic features in population studies has been discussed.

    The majority of the South African workforce are Africans, therefore potential racial differences should be considered in risk and exposure assessments in the workplace. Literature suggests African skin to be a superior barrier against permeation and irritants. Previous in vitro studies on metals only included skin from Caucasian donors, whereas this study compared the permeation of platinum through African and Caucasian skin. A donor solution of 0.3 mg/ml of potassium tetrachloroplatinate (K₂PtCl₄) dissolved in synthetic sweat was applied to the vertical Franz diffusion cells with full thickness abdominal skin. Skin from three female African and three female Caucasian donors were included (n=21). The receptor solution was removed at various intervals during the 24 h experiment, and analysed with high resolution inductively coupled plasma-mass spectrometry (ICP-MS). Skin was digested and analysed by inductively coupled plasma-optical emission spectrometry (ICP-OES). Significantly higher permeation of platinum through intact African skin (p=0.044), as well as a significantly higher mass of platinum retention in African skin in comparison with Caucasian skin (p=0.002) occurred. Significant inter-donor variation was found in both racial groups (pplatinum salts. These results are contradictory to limited literature suggesting a superior barrier in African skin and further investigation is necessary to explain the higher permeation through African skin.

    We investigated the effect of ethnicity and gender on optic nerve head morphology in healthy subjects using spectral-domain optical coherence tomography (SD-OCT). Thirty-five Indian (i.e. Indian subcontinent) females, 34 Caucasian females, 32 Indian males, and 32 Caucasian males were examined using SD-OCT (Copernicus, Optopol Technology). Disc and rim areas were larger in Caucasian males compared with females but smaller in Indians males compared with females. Indian participants had significantly larger cup areas and volumes without significant differences in retinal nerve fibre layer (RNFL) thicknesses between groups. Gender and ethnicity differences should be considered in assessment of patients.

    Prosopagnosia (PA) or face blindness is characterized by a deficiency in identifying familiar faces. Almost all reports are single cases or collections of unrelated patients who acquired prosopagnosia after brain injuries, strokes or atrophy of at least the right occipito-temporal cortex. Until 2001, the inborn form - in the absence of any brain lesions - was described in fewer than 20 probands exclusively of Caucasian origin. We recently found that in the German Caucasian population, congenital prosopagnosia has a very high prevalence of at least 2.5% and that it is genetically determined. It is best described by autosomal-dominant inheritance in the more than 50 families investigated. We therefore introduced the term non-syndromic hereditary PA for the congenital form of a monosymptomatic or isolated PA. This surprisingly high frequency in the Caucasian population prompted us to extend our search to other ethnic groups. We performed a questionnaire-based screening among 198 native Indian students at Banaras Hindu University in Varanasi. In a then selected subset, we found after further detailed diagnostic interviews one Bengali female student with visual agnosia for face recognition only. Several other members of her large family reported the same impairment of face recognition. The segregation pattern of PA in this family is also compatible with autosomal-dominant inheritance.

    Familial paraganglioma/pheochromocytoma (PGL/PCC) is genetically heterogenous with mutations in three of the four subunits of the heterotetrameric mitochondrial complex II enzyme succinate dehydrogenase (SDH) being causally responsible for the majority of cases. In addition to PGL/PCC an array of non-paraganglial tumors have been described in affected individuals. We present a 30-year follow-up on the family of a deceased patient who synchronously developed malignant neuroblastoma (NBL), PCC, and renal cell carcinoma (RCC). Other family members with late onset disease have come to our attention, and molecular study revealed a mutation in the SDHB gene. Despite the embryologic relationship, NBL has been seen in only two previous patients with familial PGL/PCC, both with deletions of the SDHB gene. Review of the literature suggests the lack of a reported association between NBL and familial PGL/PCC may be an ascertainment bias. We further suggest that study of the SDH genes in NBL survivors who develop secondary solid tumors, particularly RCC, may correct this bias, and provide for more effective and comprehensive tumor screening in this patient population.

    Full Text Available Abstract Background Models of palliative care delivery develop within a social, cultural, and political context. This paper describes the 30-year history of the National Tumor Association (ANT, a palliative care organization founded in the Italian province of Bologna, focusing on this model of home care for palliative cancer patients and on its evaluation. Methods Data were collected from the 1986-2008 ANT archives and documents from the Emilia-Romagna Region Health Department, Italy. Outcomes of interest were changed in: number of patients served, performance status at admission (Karnofsky Performance Status score [KPS], length of participation in the program (days of care provided, place of death (home vs. hospital/hospice, and satisfaction with care. Statistical methods included linear and quadratic regressions. A linear and a quadratic regressions were generated; the independent variable was the year, while the dependent one was the number of patients from 1986 to 2008. Two linear regressions were generated for patients died at home and in the hospital, respectively. For each regression, the R square, the unstandardized and standardized coefficients and related P-values were estimated. Results The number of patients served by ANT has increased continuously from 131 (1986 to a cumulative total of 69,336 patients (2008, at a steady rate of approximately 121 additional patients per year and with no significant gender difference. The annual number of home visits increased from 6,357 (1985 to 904,782 (2008. More ANT patients died at home than in hospice or hospital; this proportion increased from 60% (1987 to 80% (2007. The rate of growth in the number of patients dying in hospital/hospice was approximately 40 patients/year (p 40 increased. Mean days of care for patients with KPS > 40 exceeded mean days for patients with KPS Conclusions The ANT home care model of palliative care delivery has been well-received, with progressively growing numbers of patients served. It has resulted in a greater proportion of home deaths and in patients' accessing palliative care at an earlier point in the disease trajectory. Changes in ANT chronicle palliative care trends in general.

    Full Text Available Abstract Background There is increasing global acceptance that viscous soluble fibers lower serum LDL cholesterol (LDL-C, but most evidence for this comes from studies in Caucasians. To see if oat β-glucan lowers LDL-C in Caucasians and non-Caucasians we conducted a post-hoc analysis of the results of a randomized, controlled, double-blind, multi-center clinical trial whose primary aim was to determine if molecular-weight (MW influenced the LDL-C-lowering effect of oat β-glucan. Results Caucasian and non-Caucasian subjects with LDL-C-C ≥ 3.0 and ≤ 5.0 mmol/L (n = 786 screened, n = 400 ineligible, n = 19 refused, n = 367 randomized, n = 345 completed, n = 1 excluded for missing ethnicity were randomly assigned to consume cereal containing wheat-fiber (Control, n = 74:13 Caucasian:non-Caucasian or 3 g high-MW (3H, 2,250,000 g/mol, n = 67:19, 4 g medium-MW (4 M, 850,000 g/mol, n = 50:17, 3 g medium-MW (3M, 530,000 g/mol, n = 54:9 or 4 g low-MW (4 L, 210,000 g/mol, n = 51:12 oat β-glucan daily for 4 weeks.

    Full Text Available Abstract Background There have been no quantitative standards for volumetric and surface measurements of the mandibular condyle in Caucasian population. However, the recently developed cone-beam computed tomography (CBCT system allows measurement of these parameters with high accuracy. Methods CBCT was used to measure the condylar volume, surface and the volume to surface ratio, called the Morphometric Index (MI, of 300 temporo-mandibular joints (TMJ in 150 Caucasian young adult subjects, with varied malocclusions, without pain or dysfunction of TMJs. Results The condylar volume was 691.26 ± 54.52 mm3 in males and 669.65 ± 58.80 mm3 in, and was significantly higher (p2 in males and 394.77 ± 60.73 mm2 in females. Furthermore, the condylar volume (693.61 ± 62.82 mm3 in the right TMJ was significantly higher than in the left (666.99 ± 48.67 mm3, p 2 in the right TMJ and 389.41 ± 56.63 mm2 in the left TMJ; t = 3.29; p Conclusion These data from temporomandibular joints of patients without pain or clinical dysfunction might serve as examples of normal TMJ's in the general population not seeking orthodontic care.

    2013-11-01

    Full Text Available Background: BMI is known to have limited accuracy, which is different for males and females with similar body fat content. That is why Bergman et al. (Obesity 2011;19:1083-1089 introduced an alternative variable of obesity, called the body adiposity index (BAI. Their primary research was conducted in samples of Mexican-American and African-American populations. The objective of our research was to investigate the sex-specific relationship between both BMI and BAI and body fat content in a healthy Caucasian population. The accuracy of both indexes was compared. Methods: 684 women and 528 men aged 20-22 years with Caucasian origin only participated in the study. Participants were students of universities in southern Poland. They had no indication of cardiometabolic problems, as evaluated by interview. Results: The study revealed that BAI is a more sensitive method in assessing obesity in Caucasian males rather than BMI. In the population of Caucasian women BAI results indicate a significant underestimation of obesity. Conclusion: The fact that there is a high statistical correlation between BAI and % fat mass among obese and overweight men and women suggests that BAI could be highly specific provided that the BAI cutoffs will be adapted to the European population.

    Racial differences in men's preferences for African-American and Caucasian women's body size and shape were examined. As expected, there was a trend for African-American men to choose ideal figures with a lower waist-to-hip ratio (WHR), which is associated with a more curvaceous figure. Contrary to expectations, however, African-American men did not choose heavier female figures as ideal. In fact, both groups chose underweight and normal weight figures as ideal. The results from this study suggest that while preferences for WHR may continue to be associated with cultural factors, African-American and Caucasian men may have become more similar than different in their preferences for female weight. Also, the results suggest that within the African-American sample, there were two subsamples with regard to WHR preferences, with one subgroup endorsing the same ideal WHR as their Caucasian counterparts. The results are discussed in terms of possible changes to cultural values that may be reflected in a change in what is considered attractive.

    2011-06-01

    Within dominant American culture, females often learn to view themselves from an observer's perspective and to treat themselves as objects to be looked at (i.e., self-objectification), which can result in negative outcomes. Body surveillance (the indicator of self-objectification) has been found to predict concern with weight/shape in predominantly Caucasian samples, but research has not yet examined the potential reciprocal relations between body surveillance and weight/shape concern. Participants were 226 women attending a Midwestern university (70 self-identified as African American and 156 as Caucasian) who provided data at two time points, spaced about 5 months apart. Results revealed that downward spirals of body surveillance and weight/shape concern were apparent for the Caucasian but not the African American women. However, there was evidence that body surveillance helped account for change in weight/shape concern for the African American women.

    The incidence and clinical features of sarcoidosis were studied in a retrospective survey of 156 patients attending two South London hospitals between 1969 and 1982. Sixty-eight patients were Caucasian, 59 were Black West Indian or African immigrants and 29 were immigrants racially derived from Indo-Pakistan (Asians). The annual incidence of sarcoidosis in the local community in 1977-78 was 19.8 per 10(5) for Blacks and 16.8 per 10(5) for Asians compared with 1.5 per 10(5) for Caucasians. Erythema nodosum was a more common presenting feature in Caucasians than in Blacks (P less than 0.001) or Asians (P less than 0.05). Blacks developed sarcoidosis at a later age than Caucasians (P less than 0.05) and were less likely to present as a chance finding on a chest radiograph (P less than 0.05). They had more widespread extrathoracic disease than Caucasians (P less than 0.001) and were more commonly treated with corticosteroids (P less than 0.001). In the Asians there was a male predominance compared with Caucasians (P less than 0.01). Asians also had more extrathoracic sarcoidosis than Caucasians (P less than 0.001) and more of them were treated with corticosteroids (P less than 0.05). A stage 2 chest radiograph at presentation (P less than 0.05) and skin sarcoidosis (P less than 0.05) were less common in Asians than in Blacks, but otherwise there were no significant differences between the two groups. In this study the incidence of sarcoidosis in Asians approached that in Blacks, while the clinical features were intermediate in severity between Blacks and Caucasians. In both Blacks and Asians the disease was more common, more severe and more extensive than in Caucasians.

    Given that parenting practices have been linked to suicidal behavior in adolescence, examining the moderating effect of parenting styles on suicidal behavior early in development could offer potential insight into possible buffers as well as directions for suicide prevention and intervention later in adolescence. Hence, the moderating effects of parenting styles, including authoritarian, permissive, and features of authoritative parenting, on depressed and aggressive children's suicidal behavior, including ideation and attempts, were evaluated with young children (N = 172; 72% male, 28% female) ranging from 6 to 12 years of age. African American (69%) and Caucasian (31%) children admitted for acute psychiatric inpatient care completed standardized measures of suicidal behavior, depressive symptoms, and proactive and reaction aggression. Their parents also completed standardized measures of parental distress and parenting style. Hierarchical regression analyses revealed that, while statistically controlling for age and gender, children who endorsed more depressive symptoms or reactive aggression reported more current and past suicidal behavior than children who endorsed fewer depressive or aggressive symptoms. The significant positive relationship observed between depressive symptoms and childhood suicidal behavior, however, was attenuated by parental use of authoritarian parenting practices for African-American and older children but not for younger and Caucasian children. The ethnic/racial difference observed for the buffering effect of authoritarian parenting practices offers potential theoretical and clinical implications for conceptualizing the moderating effects of parenting styles on African-American and Caucasian children's suicidal behavior.

    Full Text Available Background: Research regarding risk factors and prevalence of low bone min-eral density (BMD among African-American and Caucasian college-aged wom-en are limited. The objective of this cross-sectional study was to determine if selected predictors of BMD in African-American and Caucasian college-aged women differ by race.Methods: A total of 101 local African-American (n=50 and Caucasian (n=51 females, ages 18 to 30 years, were in this study. All data were collected in the Bone Density and Body Composition Laboratory. BMD was measured using DXA technology. Race, family history of osteoporosis, BMI, current physical activity, osteoporosis knowledge, length of time on oral contraceptives, age at menarche and calcium intake were included in the multiple regression analyses with spinal and femoral BMD as dependent variables.Results: Overall, 38.6% had low spinal BMD and 7.9% had low femoral BMD. BMI (β=0.073, R2 = .148, P = .001, 95% CI [0.030, 0.116] and current physical activity (β=0.071, R2 = .148, P = .017, 95% CI [0.013, 0.129] were the only variables that were statistically significant in predicting spinal BMD. BMI (β=0.056, R2 = .13, P = .010, 95% CI [0.014, 0.098] and current physical activ-ity (β=0.078, R2 = .13, P = .007, 95% CI [0.022, 0.134] were also the only varia-bles that were statistically significant in predicting femoral BMD. Race was not a significant predictor of spinal or femoral BMD.Conclusion: It is imperative for both African-American and Caucasian women to engage in osteoporosis-preventive behaviors.

    @@ Fertilisation in mammals involves many synchronized steps including spermegg adhesion.Prior to sperm-oolemma fusion,spermatozoa need to undergo the acrosome reaction (AR) or exocytosis.The universal belief,for many years,has been that the AR was initiated upon binding to the zona pellucida (ZP).As such acrosomal proteins were not thought to be involved in the primary contact with the ZP.These proteins were only suggested to be biologically relevant once the sperm were attached to the ZP and during subsequent events.However,recent data in the mouse have unequivocally demonstrated that spermatozoa can begin exocytosis before contact with ZP.1 It is a remarkable finding as not only will the interpretation of the interaction between sperm and cumulus cells need to be revised,but the processes of capacitation,vesiculation and exposure of acrosomal content need reexamination.

  3. Biodiversity conservation in Swedish forests: ways forward for a 30-year-old multi-scaled approach.

    Science.gov (United States)

    Gustafsson, Lena; Perhans, Karin

    2010-12-01

    A multi-scaled model for biodiversity conservation in forests was introduced in Sweden 30 years ago, which makes it a pioneer example of an integrated ecosystem approach. Trees are set aside for biodiversity purposes at multiple scale levels varying from individual trees to areas of thousands of hectares, with landowner responsibility at the lowest level and with increasing state involvement at higher levels. Ecological theory supports the multi-scaled approach, and retention efforts at every harvest occasion stimulate landowners' interest in conservation. We argue that the model has large advantages but that in a future with intensified forestry and global warming, development based on more progressive thinking is necessary to maintain and increase biodiversity. Suggestions for the future include joint planning for several forest owners, consideration of cost-effectiveness, accepting opportunistic work models, adjusting retention levels to stand and landscape composition, introduction of temporary reserves, creation of "receiver habitats" for species escaping climate change, and protection of young forests.

    The aims of this study were to determine Japanese cephalometric norms in the antero-posterior and vertical dimension, and to test the hypothesis that there are racial differences in cephalometric measurements between Japanese and Caucasian norms. Radiographs were obtained from 25 healthy Japanese males (aged 25.1 +/- 2.7 years) and 24 healthy Japanese females (aged 23.6 +/- 1.3 years). Inclusion criteria were an ANB angle between 2 and 5 degrees, a normal occlusion with minor or no crowding, all teeth present except third molars, no previous orthodontic treatment, and no prosthetic replacement of teeth. Two angular and five linear measurements were constructed for the skeletal hard tissue analysis, one angular and six linear measurements for the dental hard tissue analysis, and two angular and seven linear measurements for the soft tissue analysis. The mean and standard deviations for the hard and soft tissue measurements were determined for each gender. Unpaired t-tests were used to determine the mean differences for each cephalometric measurement between the Japanese and the Caucasians. In the antero-posterior dimension, the Japanese subjects had a significantly more retruded chin position (P vertical dimension, the Japanese had a significantly steeper mandibular plane (P cephalometric measurements might be helpful to formulate treatment plans for Japanese patients.

    The purpose of this study was to examine high school students' math values, perceived math achievement, and STEM career choice. Participants (N=515) were rural high school students from the U.S. Northwest. Data was collected by administering the "To Do or Not to Do:" STEM pilot survey. Most participants (n=294) were Latinos, followed by Caucasians (n=142). Fifty-three percent of the students rated their math achievement as C or below. Of high math students, 57% were male. Females were 53% of low math students. Caucasians (61%) rated themselves as high in math in a greater proportion than Latinos (39%). Latinos (58%) rated themselves as low in math in a greater proportion than Caucasians (39%). Math Values play a significant role in students' perceived math achievement. Internal math values (r =.68, R2 =.46, p =.001) influenced perceived math achievement regardless of gender (males: r =.70, R2 =.49, p =.001; females: r =.65, R2 =.43, p =.001), for Latinos (r =.66, R2 =.44, p =.001), and Caucasians (r =.72, R2 =.51, p =.001). External math values (r =.53, R2 =.28, p =.001) influenced perceived math achievement regardless of gender (males: r =.54, R2 =.30, p =.001; females: r =.49, R2 =.24, p =.001), for Latinos (r =.47, R2 =.22, p =.001), and Caucasians (r =.58, R2 =.33, p =.001). Most high-math students indicated an awareness of being good at math at around 11 years old. Low-math students said that they realized that math was difficult for them at approximately 13 years of age. The influence of parents, teachers, and peers may vary at different academic stages. Approximately half of the participants said there was not a person who had significantly impacted their career choice; only a minority said their parents and teachers were influencing them to a STEM career. Parents and teachers are the most influential relationships in students' career choice. More exposure to STEM role models and in a variety of professions is needed.

    Full Text Available Managing ecosystems requires understanding how people use and value them. The objective of this study was to examine gender differences in resource use and perceptions of environmental quality in Native Americans and Caucasians interviewed at an Indian festival in East-central Idaho. More men than women engaged in consumptive activities, but there were no differences for non-consumptive or religious/spiritual. More Caucasian males engaged in hunting, and more females engaged in collecting herb and, berries, and bird-watching. More Native American males engaged in hunting and fishing, and more females engaged in picnics and walking/running. Women had higher rates of hike, walk and bike than did men, and there were no ethnic differences. The data indicate that both the percent participation and the frequency of participation varied both ethnically and by gender.

    We describe a 53-year-old Caucasian woman with a 19-year history of an evolving amyotrophy confined to her dominant right arm and hand. Although this atypical case of a late-onset monomelic amyotrophy in some respects mimics Hirayama disease or O'Sullivan-McLeod syndrome, it does not conform precisely with either of those disorders. We compare this individual's difficulties and clinical temporal profile to other disorders considered in the differential diagnoses with regard to her evolving clinical setting.

    INTRODUCTION Class II malocclusion affects about 15 % of the US population and is characterized by a convex profile and occlusion disharmonies. The specific etiological mechanisms resulting in the range of Class II dento-skeletal combinations observed is not yet understood. Most studies describing the class II phenotypic diversity have utilized moderate sample sizes or have focused on younger individuals that later in life may outgrow their class II discrepancies; such a focus may also preclude the visualization of adult class II features. The majority have utilized simple correlation methods resulting in phenotypes that may not be generalizable to different samples and thus may not be suitable for studies of malocclusion etiology. The purpose of this study is to address these knowledge gaps by capturing the maximum phenotypic variation present in a large Caucasian sample of class II individuals selected with strict eligibility criteria and rigorously standardized multivariate reduction analyses. METHODS Sixty-three lateral cephalometric variables were measured from pre-treatment records of 309 Class II Caucasian adults (82 males, 227 females; ages 16–60 years). Principal component analysis (PCA) and cluster analysis were used to generate comprehensive phenotypes in an effort to identify the most homogeneous groups of individuals reducing heterogeneity and improving the power of future malocclusion etiology studies. RESULTS PCA resulted in 7 principal components that accounted for 81% of the variation. The first three components represented variation on mandibular rotation, upper incisor angulation and mandibular length, respectively. The cluster analysis identified 5 distinct Class II phenotypes. CONCLUSIONS A comprehensive spectrum of Class II phenotypic definitions was obtained that could be generalized to other samples advancing our efforts to the identification of etiological factors underlying Class II malocclusion.

    Menopause is one of the crucial physiological events during the life of a woman. Transition of menopause status is accompanied by increased risks of various health problems such as osteoporosis. Peripheral blood monocytes can differentiate into osteoclasts and produce cytokines important for osteoclast activity. With quantitative proteomics LC-nano-ESI-MS(E) (where MS(E) is elevated-energy MS), we performed protein expression profiling of peripheral blood monocytes in 42 postmenopausal women with discordant bone mineral density (BMD) levels. Traditional comparative analysis showed proteins encoded by four genes (LOC654188, PPIA, TAGLN2, YWHAB) and three genes (LMNB1, ANXA2P2, ANXA2) were significantly down- and upregulated, respectively, in extremely low- versus high-BMD subjects. To study functionally orchestrating groups of detected proteins in the form of networks, we performed weighted gene coexpression network analysis and gene set enrichment analysis. Weighted gene coexpression network analysis showed that the module including the annexin gene family was most significantly correlated with low BMD, and the lipid-binding related GO terms were enriched in this identified module. Gene set enrichment analysis revealed that two significantly enriched gene sets may be involved in postmenopausal BMD variation by regulating pro-inflammatory cytokines activities. To gain more insights into the proteomics data generated, we performed integrative analyses of the datasets available to us at the genome (DNA level), transcriptome (RNA level), and proteome levels jointly.

METHODOLOGY/PRINCIPAL FINDINGS: We investigated the association between 25-hydroxy-vitamin D (25(OHD, skin type and ultraviolet exposure in 1414 Caucasian females in the UK. Mean age of the cohort was 47 years (18-79 and mean 25(OHD levels were 77 nmol/L (6-289. 25(OHD levels were strongly associated with season of sampling with higher levels in the spring and summer months (p<0.0001. Light skin types (skin type 1 and 2 have lower levels of 25(OHD (mean 71 nmol/L compared to darker skin types (skin type 3 and 4 (mean 82 nmol/L after adjusting for multiple confounders (p<0.0001. The trend for increasing risk of low vitamin D with fairer skin types was highly significant despite adjustment for all confounders (p = 0.001. CONCLUSIONS/SIGNIFICANCE: Contrary to previous studies across different ethnic backgrounds, this study within Caucasian UK females shows that fair skin types have lower levels of 25(OHD compared to darker skin types with potential detrimental health effects. Public health campaigns advocating sun avoidance in fair skinned individuals may need to be revised in view of their risk of vitamin D deficiency.

    Full Text Available A multicentre, cross-sectional study was carried out in six centres across Canada to establish a national standard for pulmonary function tests using healthy, lifetime nonsmokers, with each centre aiming to test 10 men and 10 women from each decade from 20 to 80 years of age. Data from each centre were used to derive prediction equations for each centre, and pooled data from all centres (total: 327 women and 300 men were used to derive Canadian predicted equations. The predictive models were compared with three widely used published models for selected tests. It was found that, in general, the equations modelled for each centre could be replaced by the models obtained when pooling all data (Canadian model. Comparisons with the published references showed good agreement and similar slopes for most tests. The results suggest that pulmonary function test results obtained from different centres in Canada were comparable and that standards currently used remain valid for Canadian Caucasians.

  20. Addison's Disease and Possible Cannabis Withdrawal Syndrome Presenting as an Eating Disorder in a Thirty-Year-Old Female

    Science.gov (United States)

    2017-01-01

    A 30-year-old female with a history of anxiety, cannabis use, and Avoidant/Restrictive Food Intake Disorder presented for residential treatment of a Cannabis Use Disorder. Upon arrival, she had not eaten for two days and was found to be hypotensive with electrolyte disturbances. She was admitted to a nearby hospital, where the Internist diagnosed her with Addison's disease. She was treated with corticosteroid therapy, with rapid normalization of her electrolytes, eating, and anxiety. This is the first published case of undiagnosed Addison's disease presenting as an eating disorder, with cannabis use likely contributing to symptoms. This case elucidates the importance of ruling out other biologic and psychologic causes of clinical presentations before an eating disorder diagnosis can be made.

    INTRODUCTION Class III malocclusion is characterized by a composite of dento-skeletal patterns that lead to the forward positioning of the mandibular teeth in relation to the maxillary teeth and a concave profile. Environmental and genetic factors are associated with this condition, which affects 1% of the US population and imposes significant esthetic and functional burdens on affected individuals. The purpose of this study was to capture the phenotypic variation present in a large sample of white adults with Class III malocclusion by using multivariate reduction methods. METHODS Sixty-three lateral cephalometric variables were measured from pre-treatment records of 292 Class II Caucasian adults (126 males, 166 females; ages 16-57 years). Principal component analysis and cluster analysis were used to capture the phenotypic variation and identify the most homogeneous groups of individuals to reduce genetic heterogeneity. RESULTS Principal component analysis resulted in 6 principal components that accounted for 81.2% of the variation. The first three components represented variations in mandibular horizontal and vertical position, maxillary horizontal position, and mandibular incisor angulation, respectively. The cluster model identified 5 distinct subphenotypes of Class III malocclusion. CONCLUSIONS A spectrum of phenotypic definitions was obtained replicating results of previous studies and supporting the validity of these phenotypic measures in future research of genetic and environmental etiology of Class III malocclusion.

    The all-female Caucasian rock lizard species Darevskia dahli and other parthenogenetic species of this genus reproduce normally via true parthenogenesis. Previously, the genetic diversity of this species was analyzed using allozymes, mitochondrial DNA, and DNA fingerprint markers. In the present study, variation at three microsatellite loci was studied in 111 specimens of D. dahli from five populations from Armenia, and new information regarding clonal diversity and clone formation in D. dahli was obtained that suggests a multiple hybridization origin. All individuals but one were heterozygous at the loci studied. Based on specific allele combinations, 11 genotypes were identified among the individuals studied. Individuals with the same genotypes formed distinct clonal lineages: one major clone was represented by 72 individuals, an intermediate clone was represented by 21 individuals, and nine other clones were rare and represented by one or several individuals. A new approach based on the detection and comparison of genotype-specific markers formed by combinations of parental-specific markers was developed and used to identify at least three hybridization founder events that resulted in the initial formation of one major and two rare clones. All other clones, including the intermediate and seven rare clones, probably arose through postformation microsatellite mutations of the major clone. This approach can be used to identify hybridization founder events and to study clone formation in other unisexual taxa.

    The purposes of this study were to (1) measure changes in the young adult Caucasian male profile through time and (2) describe the male profile depicted in current fashion magazines. Profile photographs (n = 116) of male models collected from leading fashion magazines of the last 65 years were analyzed. They were reproduced as slides, and the images were scanned and projected onto a computer monitor. Soft tissue landmarks were digitized and the profiles were corrected for size differences. Six linear, nine angular, and three proportional parameters were measured. Anteroposterior lip position, lip curl, and vermilion area showed statistically significant correlations (r > or = 31, p 0.05). The results showed that (1) the male profile depicted in fashion magazines has changed significantly with time and the changes were in the area of the lips; and (2) there was a trend of increasing lip protrusion, lip curl, and vermilion display. We conclude that similar to the female profile, the esthetic male profile has changed with time.

    Full Text Available Abstract Background Takotsubo cardiomyopathy is an acute cardiac syndrome characterized by transient LV regional wall motion abnormalities (with peculiar apical ballooning appearance, chest pain or dyspnea, ST-segment elevation and minor elevations of cardiac enzyme levels Case presentation A 68-year-old woman was admitted to the Emergency Department because of sudden onset chest pain occurred while transferring her daughter, who had earlier suffered a major seizure, to the hospital. The EKG showed sinus tachycardia with ST-segment elevation in leads V2–V3 and ST-segment depression in leads V5–V6, she was, thus, referred for emergency coronary angiography. A pre-procedural transthoracic echocardiogram revealed regional systolic dysfunction of the LV walls with hypokinesis of the mid-apical segments and hyperkinesis of the basal segments. Coronary angiography showed patent epicardial coronary arteries; LV angiography demonstrated the characteristic morphology of apical ballooning with hyperkinesis of the basal segments and hypokinesis of the mid-apical segments. The post-procedural course was uneventful; on day 5 after admission the echocardiogram revealed full recovery of apical and mid-ventricular regional wall-motion abnormalities. Conclusion Takotsubo cardiomyopathy is a relatively rare, unique entity that has only recently been widely appreciated. Acute stress has been indicated as a common trigger for the transient LV apical ballooning syndrome, especially in postmenopausal women. The present report is a typical example of stress-induced takotsubo cardiomyopathy in a Caucasian Italian postmenopausal woman.

    Young infants are known to prefer own-race faces to other race faces and recognize own-race faces better than other-race faces. However, it is entirely unclear as to whether infants also attend to different parts of own- and other-race faces differently, which may provide an important clue as to how and why the own-race face recognition advantage emerges so early. The present study used eye tracking methodology to investigate whether 6- to 10-month-old Caucasian infants (N = 37) have differential scanning patterns for dynamically displayed own- and other-race faces. We found that even though infants spent a similar amount of time looking at own- and other-race faces, with increased age, infants increasingly looked longer at the eyes of own-race faces and less at the mouths of own-race faces. These findings suggest experience-based tuning of the infant's face processing system to optimally process own-race faces that are different in physiognomy from other-race faces. In addition, the present results, taken together with recent own- and other-race eye tracking findings with infants and adults, provide strong support for an enculturation hypothesis that East Asians and Westerners may be socialized to scan faces differently due to each culture's conventions regarding mutual gaze during interpersonal communication.

    During platinum group metals (PGMs) refining the possibility exists for dermal exposure to PGM salts. The dermal route has been questioned as an alternative route of exposure that could contribute to employee sensitisation, even though literature has been focused on respiratory exposure. This study aimed to investigate the in vitro permeation of platinum and rhodium through intact Caucasian skin. A donor solution of 0.3mg/ml of metal, K2PtCl4 and RhCl3 respectively, was applied to the vertical Franz diffusion cells with full thickness abdominal skin. The receptor solution was removed at various intervals during the 24h experiment, and analysed with high resolution ICP-MS. Skin was digested and analysed by ICP-OES. Results indicated cumulative permeation with prolonged exposure, with a significantly higher mass of platinum permeating after 24h when compared to rhodium. The mass of platinum retained inside the skin and the flux of platinum across the skin was significantly higher than that of rhodium. Permeated and skin retained platinum and rhodium may therefore contribute to sensitisation and indicates a health risk associated with dermal exposure in the workplace.

    The Ubiquitin Specific Protease 26 gene is a testis-specific gene that is located on the X chromosome. Sequence variants of this gene were previously reported in men with azoospermia caused by defects at the level of spermatogenesis. Especially a cluster of three changes (c.370_371insACA, c.494T>C and c.1423C>T) was frequently observed. To further define the role of this cluster of sequence variants in the USP26 gene, we have now analysed 202 control samples and 146 patients of Caucasian origin with cryptozoospermia or oligozoospermia. The detection method was based on a restriction reaction, by which the change c.494T>C can be detected. In none of the patients, the change c.494T>C was observed. Only in one man with normal spermatogenesis this sequence variant was detected. Sequencing can confirm the presence of the three changes of the USP26 gene. These data indicate that the cluster of changes is not restricted to men with severe testicular dysfunction.

    Full Text Available The article analyzes the retrospective transformation of ethno-demographic structure of the population of Krasnodar region from the perspective of representation, dynamics and characteristics of reproduction of Caucasian ethnic groups in the post-Soviet period. On the basis of census data in 1989, 2002 and 2010 describes the general trends, and compares the demographic development of the Caucasian ethnic groups in the region. The concept of Caucasian ethnicity used in its geographical rather than linguistic or cultural and historical significance. The authors classify living in the Caucasus region, minority, into several groups: indigenous peoples of the region, internal diaspora indigenous peoples of the Russian Federation, the Diaspora peoples who have their own national state or ethnic core outside of Russia. A comparison of the natural reproduction and migration of Caucasian ethnic groups in the region, analyzed the regional dynamics of migration as a factor of change in the population of the Caucasian diaspora. At the same time the features of the regional identity of the Caucasian communities, causes the appearance of new forms of ethnic identification. On the example of "Circassian issue" through the process of ethnic mobilization in modern conditions, and on the example of the Turkish community analyzes the problem of ethnic segregation in the province, spread ethnophobia, which resulted in mass re-emigration. At the end of the article presents forecast of development of processes of ethno-demographic reproduction of Caucasian minorities in the Krasnodar Territory.

    Full Text Available Background. Corynebacterium kroppenstedtii (Ck was first described in 1998 from human sputum. Contrary to what is observed in ethnic groups such as Maori, Ck is rarely isolated from breast abscesses and granulomatous mastitis in Caucasian women. Case Presentation. We herein report a case of recurrent breast abscesses in a 46-year-old Caucasian woman. Conclusion. In the case of recurrent breast abscesses, even in Caucasian women, the possible involvement of Ck should be investigated. The current lack of such investigations, probably due to the difficulty to detect Ck, may cause the underestimation of such an aetiology.

    Because previous studies have shown that serum uric acid levels are higher in members of the Filipino and Maori races than in Caucasians, and because gout seemed unexpectedly common in the Chinese population of Vancouver, a study of serum uric acid levels in Caucasian, Chinese and Haida Indian males was undertaken. The serum uric acid levels of 200 Caucasian, 100 Chinese and 237 Haida Indian males were determined by the ultraviolet spectrophotometric method of Dubbs, which gives a result 0.5 mg. % below that of the more commonly employed method of Grayzel. The mean level of the Caucasians was 4.55 mg. % and that of the Haida Indians 4.41 mg. %; in contrast, the Chinese mean was 5.44 mg. %, a significantly higher figure than the means of the other two groups. No explanation for this finding can be given at present.

    This study describes HIV, sexually transmitted infections (STI) and risk factors associated with Mycoplasma genitalium among female sex workers (FSWs) in four cities in Honduras. In 2006, 795 FSWs from Tegucigalpa, San Pedro Sula, La Ceiba and Comayagua were recruited using respondent-driven sampling (RDS) and tested for HIV prevalence and STI. HIV prevalence ranged from no infections in Comayagua to 5.4% in Tegucigalpa. With the exception of Comayagua, more than 20% of FSWs were infected with M. genitalium. M. genitalium in the aggregated cities was associated with HIV positivity, being aged ≤30 years old, drinking alcohol more than once weekly and always using condoms with regular clients in the past month. In comparison with a 2001 surveillance study we found lower rates of HIV infection. Interventions for HIV control and prevention among FSWs, including promotion of condom use, are needed in Honduras.

Pathological examination revealed non-Hodgkin’s lymphoma of diffuse large B-cell type and mucosa-associated lymphoid tissue type, stage IE. The patient refused radiotherapy. Accordingly, we started CHOP-R chemotherapy. She received a total of 6 cycles of CHOP and 8 cycles of rituximab. Patient follow-up was done 3 months later through CT scan and cytoscopy confirming the complete remission. The patient has been disease-free for 4 years. We reviewed 26 cases of this rare entity reported previously.

    In racial disparities research, perceived discrimination is a proposed risk factor for unfavorable health outcomes. In a proposed "threshold-constraint" theory, discrimination intensity may exceed a threshold and require coping strategies, but social constraint limits coping options for African Americans, who may react to perceived racial discrimination with disengagement, because active strategies are not viable under this social constraint. Caucasian Americans may experience less discrimination and lower social constraint, and may use more active coping strategies. There were 213 African Americans and 121 Caucasian Americans with cancer who participated by completing measures of mistreatment, coping, and quality of life. African Americans reported more mistreatment than Caucasian Americans (p quality of life relationship, disengagement was a significant mediator for Caucasians (B = -.39; CI .13-.83) and African Americans (B = -.20; CI .07-.43). Agentic coping was a significant mediator only for Caucasians (B = -.48; CI .18-.81). Discrimination may exceed threshold more often for African Americans than for Caucasians and social constraint may exert greater limits for African Americans. Results suggest that perceived discrimination affects quality of life for African Americans with cancer because their coping options to counter mistreatment, which is racially based, are limited. This process may also affect treatment, recovery, and survivorship.

    Super Koropon primer (MB0125-055) plays a significant role in the corrosion protection of areas throughout the Orbiter. Because the Shuttle Program relies so heavily upon the performance of the Koropon primer, it is necessary to fully understand all aspects of the behavior of the coating. One area where little understanding of the Koropon primer still exists is the level of risk associated with age related degradation. Recently, efforts were undertaken to better understand the age life of the Koropon primer and to gain some insight into the aging process of this coating. In that study, an aluminum access panel from the Orbiter Enterprise was used to investigate the performance of the old Koropon film. A control panel was also used to study the performance of new Koropon coating. Preliminary investigations into the performance of aged Super Koropon primer indicated a significant decrease in corrosion protection. This investigation serves as an example of how Focused Ion Beam/Scanning Microscopy can be used to characterize the changes that occur as coatings age.

    Kerhervé, Hugo A.; Askew, Christopher D.; Solomon, Colin

    2016-01-01

    Purpose High intensity interval training (HIIT) has been proposed as a time-efficient format of exercise to reduce the chronic disease burden associated with sedentary behaviour. Changes in oxygen utilisation at the local tissue level during an acute session of HIIT could be the primary stimulus for the health benefits associated with this format of exercise. The recovery periods of HIIT effect the physiological responses that occur during the session. It was hypothesised that in sedentary individuals, local and systemic oxygen utilisation would be higher during HIIT interspersed with active recovery periods, when compared to passive recovery periods. Methods Twelve sedentary males (mean ± SD; age 23 ± 3 yr) completed three conditions on a cycle ergometer: 1) HIIT with passive recovery periods between four bouts (HIITPASS) 2) HIIT with active recovery periods between four bouts (HIITACT) 3) HIITACT with four HIIT bouts replaced with passive periods (REC). Deoxygenated haemoglobin (HHb) in the vastus lateralis (VL) and gastrocnemius (GN) muscles and the pre-frontal cortex (FH), oxygen consumption (VO2), power output and heart rate (HR) were measured continuously during the three conditions. Results There was a significant increase in HHb at VL during bouts 2 (p = 0.017), 3 (p = 0.035) and 4 (p = 0.035) in HIITACT, compared to HIITPASS. Mean power output was significantly lower in HIITACT, compared to HIITPASS (p < 0.001). There was a significant main effect for site in both HIITPASS (p = 0.029) and HIITACT (p = 0.005). There were no significant differences in VO2 and HR between HIITPASS and HIITACT. Conclusions The increase in HHb at VL and the lower mean power output during HIITACT could indicate that a higher level of deoxygenation contributes to decreased mechanical power in sedentary participants. The significant differences in HHb between sites indicates the specificity of oxygen utilisation. PMID:27677081

    It is uncertain when female circumcision was first practiced, but it certainly preceded the founding of both Christianity and Islam. A review of past and current historical, popular and professional literature was undertaken, and 4 types of female circumcision were identified. Typically female circumcision is performed by a local village practitioner, lay person or by untrained midwives. Female genital mutilation is not accepted by any religious or medical opinion, and is a violation of human rights against helpless individuals who are unable to provide informed consent and who must therefore be protected through education and legislation. Complications of female circumcision can present after many years. Any medical practitioner (either for adult or pediatric) can be confronted with this issue of female circumcision, even in countries where this custom is not present, thus mandating the understanding of this complex issue.

    The oxytocin receptor gene (OXTR) has been studied in autism because of the role of oxytocin (OT) in social cognition. Linkage has also been demonstrated to the region of OXTR in a large sample. Two single nucleotide polymorphisms (SNPs) and a haplotype constructed from them in OXTR have been associated with autism in the Chinese Han population. We tested whether these associations replicated in a Caucasian sample with strictly defined autistic disorder. We genotyped the two previously associated SNPs (rs2254298, rs53576) in 57 Caucasian autism trios. Probands met clinical, ADI-R, and ADOS criteria for autistic disorder. Significant association was detected at rs2254298 (p=0.03) but not rs53576. For rs2254298, overtransmission of the G allele to probands with autistic disorder was found which contrasts with the overtransmission of A previously reported in the Chinese Han sample. In both samples, G was more frequent than A. However, in our Caucasian autism trios and the CEU Caucasian HapMap samples the frequency of A was less than that reported in the Chinese Han and Chinese in Bejing HapMap samples. The haplotype test of association did not reveal excess transmission from parents to affected offspring. These findings provide support for association of OXTR with autism in a Caucasian population. Overtransmission of different alleles in different populations may be due to a different pattern of linkage disequilibrium between the marker rs2254298 and an as yet undetermined susceptibility variant in OXTR.

    Full Text Available Body-surface chemical compounds were studied in 1-day-old nest workers and foragers both in Buckfast and Caucasian bees. The workers of these two age-castes were sampled twice in each of two consecutive years. Body-surface lipids were determined by means of gas chromatography, with a GCQ mass spectrometer. Protein concentrations and activities on the body surface were examined in bee cuticle rinsings obtained from worker bees according to the methods of Lowry, of Anson, and of Lee and Lin. Protease and protease inhibitor activities were determined. Polyacrylamide gel electrophoresis was performed. Caucasian bees, particularly foragers, had more lipids, but Buckfast bees (two age-castes had more proteins on their body surfaces. A total of 17 alkane types (C17 - C33, 13 alkene types (C21 - C33, 21 esters (C12 - C32, and a phenol (C14 were detected in both races. Alkene C33 was detected only in Caucasian bees. More alkanes, esters, and phenols were found in Caucasian 1-day-old nest workers and foragers than in these age-castes of Buckfast bees. The protein concentration and protease inhibitor activities were lower in Caucasian bees that had higher protease activities. These values corresponded with specific numbers and widths of the electrophoretic bands.

    Full Text Available INTRODUCTION: The objective of this study was to identify the patterns of dental variables of adolescent Japanese-Brazilian descents with normal occlusion, and also to compare them with a similar Caucasian and Mongoloid sample. METHODS: Lateral cephalometric radiographs were used to compare the groups: Caucasian (n = 40, Japanese-Brazilian (n = 32 and Mongoloid (n = 33. The statistical tests used were one-way ANOVA and ANCOVA. The cephalometric measurements used followed the analyses of Steiner, Tweed and McNamara Jr. RESULTS: Statistical differences (P < 0.05 indicated a smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the Caucasian sample, although with similar values to the Mongoloid group. CONCLUSION: The dental patterns found for the Japanese-Brazilian descents were, in general, more similar to those of the Mongoloid sample.

    Thyrotoxic periodic paralysis is a potentially fatal complication of hyperthyroidism, more common in Asian races, which is defined by a massive intracellular flux of potassium. This leads to profound hypokalaemia and muscle paralysis. Although the paralysis is temporary, it may be lethal if not diagnosed and treated rapidly, as profound hypokalaemia may induce respiratory muscle paralysis or cardiac arrest. The condition is often misdiagnosed in the west due to its comparative rarity in Caucasians; however it is now increasingly described in Caucasians and is also being seen with increasing frequency in western hospitals due to increasing immigration and population mobility. Here we describe the case of a patient with panhypopituitarism due to a craniopharyngioma, who developed thyrotoxic periodic paralysis due to excessive L-thyroxine replacement. This disorder has been described in Asian subjects but, to our knowledge, thyrotoxic periodic paralysis secondary to excessive L-thyroxine replacement has never been described in Caucasians.

    Few studies have assessed relationships between perceived racism, racism-related stress, and alcohol problems. The current study examined these relationships within the context of tension reduction models of alcohol consumption. Participants were 94 African American and 189 Caucasian college freshmen who completed an online survey assessing perceived racism, alcohol consequences, alcohol consumption, negative affect, and deviant behavior. Hierarchical multiple regressions indicated that racism-related stress predicted alcohol consequences for both African American and Caucasian college students, even after controlling for alcohol consumption, negative affect, and behavioral deviance. The frequency of racist events predicted alcohol consequences for Caucasian but not African American students. These findings highlight the need to address racism and racism-related stress in college-based alcohol prevention and intervention efforts.

    The hypothalamo-pituitary-adrenal axis and sympathetic nervous system (SNS) interact to maintain cardiovascular and metabolic homeostasis, especially during stress. Pima Indians have a low SNS activity, which may contribute to both their increased risk of obesity and reduced risk of hypertension. Although glucocorticoids inhibit SNS activity, Pima Indians are not hypercortisolemic compared with Caucasians. This does not exclude the possibility that the SNS is more responsive to an inhibitory effect of cortisol in the former than in the latter group. We measured fasting plasma ACTH and cortisol and muscle SNS activity [muscle sympathetic nervous system activity (MSNA), microneurography] in 58 males [27 Pimas/31 Caucasians]. Seven Pimas and 12 Caucasians were randomized to a double-blind, placebo-controlled, cross-over study to examine the effect of overnight partial chemical adrenalectomy (metyrapone) followed by cortisol replacement (hydrocortisone) on plasma ACTH, cortisol, and MSNA. There were no ethnic differences in fasting plasma ACTH or cortisol, but MSNA adjusted for percent body fat was lower in Pimas than in Caucasians (P fasting cortisol and basal MSNA. Administration of metyrapone did not lead to significant changes in MSNA. In response to a hydrocortisone infusion, MSNA decreased in Pima Indians (P = 0.03) but not in Caucasians (P = 0.7). Our data indicate that the low SNS activity that predisposes Pima Indians to obesity is not due to a tonic inhibitory effect of cortisol. However, an acute release of cortisol is likely to more effectively contain sympathoexcitation during stress in Pima Indians than in Caucasians, which may be an important mechanism of cardioprotection in this Native American population.

    Objective Recent studies have identified a number of novel rheumatoid arthritis (RA) loci in Caucasian populations. In this study, we sought to determine whether the genetic variants at 4q27, 6q23, CCL21, TRAF1/C5, and CD40 identified in Caucasians are also associated with RA in a Korean case-control collection. We also comprehensively evaluated the genetic variation within PTPN22, a well established autoimmune disease-associated gene. Methods We designed a Sequenom iPlex experiment to thoroughly evaluate the PTPN22 linkage disequilibrium region using tag SNPs and disease-associated SNPs at 5 other previously reported Caucasian RA-associated loci in 1123 RA Korean RA patients and 1008 ethnically matched controls. We also re-sequenced the PTPN22 gene to look for novel coding variants that might be contributing to disease in this population. Results None of the Caucasian RA susceptibility loci contributed significantly to disease in Koreans. Tag SNPs covering the PTPN22 linkage disequilibrium block, while polymorphic, did not reveal any disease association and re-sequencing did not identify any new common coding region variants in this population. The 6q23 and 4q27 SNPs assayed were non-polymorphic in this population and the TRAF1/C5, CD40, and CCL21 SNPs did not show any evidence for association. Conclusions Caucasian and Korean rheumatoid arthritis have different genetic risk factors. While patients of different ethnic groups share the HLA region as a major genetic risk locus, most other genes shown to be significantly associated with disease in Caucasians appear not to play a role in Korean RA.

    Adenosine is an effective treatment for androgenetic alopecia (AGA) in Japanese men and women. Adenosine exerts its effects by significantly increasing the proportion of thick hair. In this study, we assessed the clinical outcome of adenosine treatment for 6 months in 38 Caucasian men. The change in proportion of thick hair (≥60 μm) compared with baseline in the adenosine group was significantly higher than that in the placebo group (P thick hair in Caucasian men with AGA as well as in Japanese men and women.

    Full Text Available Background: Serum lutein (L and zeaxanthin (Z positively correlate with macular pigment optical density (MPOD, hence the latter is a valuable indirect tool for measuring L and Z content in the macula. L and Z have been attributed antioxidant capacity and protection from certain retinal diseases but their uptake within the eye is thought to depend on genetic, age and environmental factors. In particular gene variants within beta-carotene monooxygenase (BCMO1 are thought to modulate MPOD in the macula.Objectives: To determine the effect of BCMO1 single nucleotide polymorphisms (SNPs rs11645428, rs6420424 and rs6464851 on macular pigment optical density (MPOD in a cohort of young healthy participants of Caucasian origin with normal ocular health.Design: In this cohort study, MPOD was assessed in 46 healthy participants (22 male and 24 female with a mean age of 24 ± 4.0 years (range 19-33. The three SNPs, rs11645428, rs6420424, rs6564851 that have established associations with MPOD were determined using MassEXTEND (hME Sequenom assay. One-way analysis of variance (ANOVA was performed on groups segregated into homozygous and heterozygous BCMO1 genotypes. Correlations between body mass index (BMI, iris colour, gender, central retinal thickness (CRT, diet and MPOD were investigated.Results: MPOD did not significantly vary with BCMO1 rs11645428 (F2,41 = 0.700, p = 0.503, rs6420424 (F2,41 = 0.210, p = 0.801 nor rs6464851 homozygous or heterozygous genotypes (F2,41 = 0,13, p = 0.88, in this young healthy cohort. The combination of these three SNPs into triple genotypes based on plasma conversion efficiency did not affect MPOD (F2,41 = 0.07, p = 0.9. There was a significant negative correlation with MPOD and central retinal thickness (r = - 0.39, p = 0.01 but no significant correlation between BMI, iris colour, gender and MPOD. Conclusion: Our results indicate that macular pigment deposition within the central retina is not dependent on BCMO1 gene variant

  12. Visual perception of female physical attractiveness.

    On the basis of visual assessment of figure drawings and front/profile images, past researchers believed that the waist-hip ratio (WHR) and the body mass index (BMI) were two putative cues to female physical attractiveness. However, this view was not tested on three-dimensional (3D) female images. In the present study, 3D images of 31 Caucasian females having varying body weights (BMI ranged from 16 to 35) were shown to 29 male and 25 female viewers, who were asked to rate the physical attractiveness. The results showed that the body volume divided by the square of the height, defined as volume height index (VHI), is the most important and direct visual determinant of female physical attractiveness. In determining the female attractiveness, human observers may first use VHI as a visual cue, which is also a key indicator of health and fertility owing to its strong linear relation to BMI. To fine-tune the judgement, observers may then use body proportions, the most important of which are the ratio of waist height over the chin height (WHC) (a measure of the length of legs over total tallness) and the deviation of WHR from the ideal ratio. It also appears that the effect of the body's physical parameters on the perception of female physical attractiveness conforms to Stevens' power law of psychophysics.

    2012-01-01

    African-Americans have more hypertension, stroke, and type 2 diabetes than do Caucasians. Endothelial dysfunction and insulin resistance are precursors for each. Since these diseases have origins in pediatrics and are associated with obesity, this study was designed to determine if obesity has different effects on endothelial function, insulin sensitivity, and secretion in African-American and Caucasian adolescents. Thirty-three Caucasian and 25 African-Americans (10-18 years old) were subdivided by BMI into lean, overweight, and obesity groups. Endothelial function was measured as forearm vascular resistance (FVR) over 1 min following 5 min of upper arm vascular occlusion. Insulin sensitivity and secretion were measured using intravenous glucose tolerance test and minimal model. Postocclusive FVR was significantly increased in obese African-Americans. Insulin sensitivity was reduced in obese subjects but did not differ by race. Insulin secretion was increased in African-Americans but did not differ by obesity. Subjects were subdivided into risk groups based on 20th percentile for postocclusion FVR response in lean. Seven of nine obese African-Americans were in the high risk group compared to 0 of 5 obese Caucasians. These results demonstrate that obesity significantly impairs endothelial function in African-Americans. Endothelial dysfunction likely predisposes to future cardiometabolic disease in obese African-American adolescents.

Bacillus cereus is an extremely rare cause for endocarditis in intravenous drug abusers (IVDA) or those with valvular disease or devices such as pacemakers. We report a case of B. cereus endocarditis, which, to the best of our knowledge, has never been reported in pregnancy. A 30-year-old, 25-week pregnant female presented with right shoulder pain, swelling and erythema on the lateral aspect of deltoid muscle from large abscess over her deltoid muscle. She was found to have a vegetation on the native tricuspid valve. Cultures from abscess fluid and blood cultures grew B. cereus, she was appropriately treated with antimicrobials and had favorable outcomes. There are cereus endocarditis reported but none during pregnancy. When cultures grow unusual organisms the case must be thoroughly investigated.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    Traditional body image studies have been constrained by focusing on body thinness as the sole component of attractiveness. Evidence suggests that African American women may hold a multifactorial view of attractiveness that extends beyond size to include factors such as dress attire and race. The current study employed a culturally sensitive silhouette Model Rating Task (MRT) to examine the effects of attire, body size, and race on attractiveness. Unexpectedly, minimal differences on attractiveness ratings emerged by attire, body size, or model race between African American and Caucasian women. Overall, participants preferred the dressed, underweight, and African American models. Factors such as exposure to diverse groups and changes in African American culture may explain the present findings. Future studies to delineate the components of attractiveness for African American and Caucasian women using the MRT are needed to broaden our understanding and conceptualization of attractiveness across racial groups.

    The influential roles of culture and ethnic identity are frequently cited in developing disordered eating and body dissatisfaction, constituting both protective and risk factors. For African American women, strongly identifying with African American cultural beauty ideals may protect against disordered eating to lose weight, but may actually increase risk in development of disordered eating directed at weight gain, such as binge eating. This study compares African American and Caucasian women on disordered eating measures, positing that African American women show greater risk for binge eating due to the impact of ethnic identity on body dissatisfaction. Findings indicate low levels of ethnic identity represent a risk factor for African American women, increasing the likelihood of showing greater binge eating and bulimic pathology. In Caucasian women, high levels of ethnic identity constitute a risk factor, leading to higher levels of both binge eating and global eating pathology. Implications for prevention and treatment are discussed.

    The use of body mass index (BMI) for the diagnosis of obesity has limitations, especially when comparing ethnic groups with different body proportions. The aim of this prospective study was to compare maternal body composition in early pregnancy between Caucasian Irish and Indian women. A total of 81 Indian women and 81 Irish Caucasian women were matched for age, parity and BMI. Maternal weight and height were measured, and body composition analysed using bioelectrical impedance. The Irish women were taller and weighed more than the Indian women (p<0.001). At any given BMI, the Indian women had a higher total body fat percentage, visceral fat level and high fat percentage than the Irish women (p=0.024, 0.001 and 0.001, respectively). Our findings suggest that lower BMI cut-offs should be used for screening for gestational diabetes mellitus in Indian women attending our antenatal services.

    North American Indians have a higher morbidity from gallbladder disease, diabetes mellitus and obesity than other North Americans; this may result from their food intake. Nutrient intake and meal patterns were compared in 120 Micmac Indian and 115 Caucasian women in Shubenacadie, NS. Findings were compared with the Canadian Dietary Standard (CDS) and the Nutrition Canada national and Indian survey reports. The diet of Indian women had higher carbohydrate, lower protein and lower fibre content than that of Caucasian women, who derived a higher percentage of energy from protein and had a higher intake of vitamin A, niacin and ascorbic acid. Overnight fast was longer among Indian women. A high percentage of all women studied reported diets that did not reach the CDS for total energy intake in kilocalories or for calcium, iron, vitamin A, thiamin or riboflavin.

    Cytochrome P450 1B1 (CYP1B1) is involved in the activation of many carcinogens and in the metabolism of steroid hormones. We compared allele, genotype and haplotype frequencies of six single-nucleotide polymorphisms (SNPs) within CYP1B1 among non-Hispanic Caucasians (496 cases and 498 controls) and Hispanic Caucasians (153 cases and 240 controls). In the Hispanic Caucasians, the GG genotype for rs1056836 decreased the risk for prostate cancer (PCa) when compared with the CC genotype [odds rat...

    Full Text Available OBJECTIVE: South Asians are susceptible to insulin resistance even without obesity. We examined the characteristics of body fat content, distribution and function in South Asian men and their relationships to insulin resistance compared to Caucasians. RESEARCH DESIGN AND METHODS: Twenty-nine South Asian and 18 Caucasian non-diabetic men (age 27+/-3 and 27+/-3 years, respectively underwent euglycemic-hyperinsulinemic clamp for insulin sensitivity, underwater weighing for total body fat, MRI of entire abdomen for intraperitoneal (IP and subcutaneous abdominal (SA fat and biopsy of SA fat for adipocyte size. RESULTS: Compared to Caucasians, in spite of similar BMI, South Asians had higher total body fat (22+/-6 and 15+/-4% of body weight; p-value<0.0001, higher SA fat (3.5+/-1.9 and 2.2+/-1.3 kg, respectively; p-value = 0.004, but no differences in IP fat (1.0+/-0.5 and 1.0+/-0.7 kg, respectively; p-value = 0.4. SA adipocyte cell size was significantly higher in South Asians (3491+/-1393 and 1648+/-864 microm2; p-value = 0.0001 and was inversely correlated with both glucose disposal rate (r-value = -0.57; p-value = 0.0008 and plasma adiponectin concentrations (r-value = -0.71; p-value<0.0001. Adipocyte size differences persisted even when SA was matched between South Asians and Caucasians. CONCLUSIONS: Insulin resistance in young South Asian men can be observed even without increase in IP fat mass and is related to large SA adipocytes size. Hence ethnic excess in insulin resistance in South Asians appears to be related more to excess truncal fat and dysfunctional adipose tissue than to excess visceral fat.

    We have reported that lactobionic acid is produced from lactose by Acetobacter orientalis in traditional Caucasian fermented milk. To maximize the application of lactobionic acid, we investigated favorable conditions for the preparation of resting A. orientalis cells and lactose oxidation. The resting cells, prepared under the most favorable conditions, effectively oxidized 2-10% lactose at 97.2 to 99.7 mol % yield.

    Full Text Available Abstract Background The P-glycoprotein, encoded by the ABCB1 gene, is expressed in human endothelial and mesangial cells, which contribute to control renal plasma flow and glomerular filtration rate. We investigated the association of ABCB1 variants with renal function in African and Caucasian subjects. Methods In Africans (290 subjects from 62 pedigrees, we genotyped the 2677G>T and 3435 C>T ABCB1 polymorphisms. Glomerular filtration rate (GFR was measured using inulin clearance and effective renal plasma flow (ERPF using para-aminohippurate clearance. In Caucasians (5382 unrelated subjects, we analyzed 30 SNPs located within and around ABCB1, using data from the Affymetrix 500 K chip. GFR was estimated using the simplified Modification of the Diet in Renal Disease (MDRD and Cockcroft-Gault equations. Results In Africans, compared to the reference genotype (GG or CC, each copy of the 2677T and 3435T allele was associated, respectively, with: GFR higher by 10.6 ± 2.9 (P P = 0.06 mL/min; ERPF higher by 47.5 ± 11.6 (P P = 0.007 mL/min; and renal resistances lower by 0.016 ± 0.004 (P P = 0.004 mm Hg/mL/min. In Caucasians, we identified 3 polymorphisms in the ABCB1 gene that were strongly associated with all estimates of GFR (smallest P value = 0.0006, overall P = 0.014 after multiple testing correction. Conclusion Variants of the ABCB1 gene were associated with renal function in both Africans and Caucasians and may therefore confer susceptibility to nephropathy in humans. If confirmed in other studies, these results point toward a new candidate gene for nephropathy in humans.

    Full Text Available To discover susceptibility genes of late-onset Alzheimer's disease (LOAD, we conducted a 3-stage genome-wide association study (GWAS using three populations: Japanese from the Japanese Genetic Consortium for Alzheimer Disease (JGSCAD, Koreans, and Caucasians from the Alzheimer Disease Genetic Consortium (ADGC. In Stage 1, we evaluated data for 5,877,918 genotyped and imputed SNPs in Japanese cases (n = 1,008 and controls (n = 1,016. Genome-wide significance was observed with 12 SNPs in the APOE region. Seven SNPs from other distinct regions with p-values <2×10(-5 were genotyped in a second Japanese sample (885 cases, 985 controls, and evidence of association was confirmed for one SORL1 SNP (rs3781834, P = 7.33×10(-7 in the combined sample. Subsequent analysis combining results for several SORL1 SNPs in the Japanese, Korean (339 cases, 1,129 controls and Caucasians (11,840 AD cases, 10,931 controls revealed genome wide significance with rs11218343 (P = 1.77×10(-9 and rs3781834 (P = 1.04×10(-8. SNPs in previously established AD loci in Caucasians showed strong evidence of association in Japanese including rs3851179 near PICALM (P = 1.71×10(-5 and rs744373 near BIN1 (P = 1.39×10(-4. The associated allele for each of these SNPs was the same as in Caucasians. These data demonstrate for the first time genome-wide significance of LOAD with SORL1 and confirm the role of other known loci for LOAD in Japanese. Our study highlights the importance of examining associations in multiple ethnic populations.

    Full Text Available The article specifies types of investments in human capital: spending on education, health and mobility. The author highlights the key actors invest in human capital development: the state, the corporate sector, households; emphasizes the low activity of the corporate sector and households in the process of investing in human capital. During the analysis of the problems of development of the human capital of the North Caucasian Federal District the author highlighted the interdependence of development of the productive sector of the economy and human capital: the low level of industrialization determines the gap in terms of gross regional product, high unemployment and low incomes, lack of investment in human capital of households. The article also deals with the problems of health and education in the North Caucasian Federal District: the shortage of qualified personnel, insufficient capacity of institutions. The analysis of the structure of regional budget expenditures on human capital development are pointed out. They include the spheres of health, education and culture. There is a direct and close relationship between the amount of budget spending on health, education, culture and the level of development of human capital in the country and the region. In the regions of the North Caucasian Federal District the lower level of educated population engaged in the sphere of economics was revealed. Particular attention is paid to analysis of the quality of human capital state and municipal employees of the North Caucasian Federal District, whose activities in the conditions of underdevelopment of large business, significantly affects the prospects for regional economic growth. The necessity of developing and implementing regional policies to promote health, education and culture, determines the quality of human capital in the economy.

    Full Text Available In a previously published study, we showed that expression of the ABCD3 gene increased with increasing metastatic potential in a panel of prostate cancer cell lines derived from African American and Caucasian American men. Given importance of identifying biomarker(s that can distinguish indolent versus aggressive prostate tumors, we conducted an immunohistochemical analysis of ABCD3 expression Caucasian and African American prostate tumors. ABCD3 expression in each patient population was compared with clinicopathologic characteristics, Gleason score, and age. ABCD3 expression increased with increasing Gleason score (P=0.0094, age (P=0.0014, and pathology grade (P=0.0007 in Caucasian patients. Interestingly, in the AA patients, ABCD3 expression highly increased to the same degree in both low and high Gleason score tumors. Similarly, ABCD3 expression was elevated to the same degree in BPH derived from AA. Our findings demonstrate that increased ABCD3 expression correlates with Gleason Score in CA prostate tumors. However, in AA prostate tumors, ABCD3 expression was higher and was sustained in both low Gleason and high Gleason AA tumors. While the functional role of ABCD3 in prostate cancer is not completely elucidated, this gene warrants further study as a potential biomarker for aggressive prostate.

    Chlorzoxazone's disposition after oral administration was determined in 20 young healthy Caucasian men and a similar group of Japanese men. The drug's plasma concentrations were significantly higher and its rate of elimination slower in Japanese compared to Caucasian men. Accordingly, chlorzoxazone's oral clearance was smaller (40%) in Japanese men and a similar difference (30%) was still apparent after normalizing for body weight (3.74 +/- 1.23 versus 5.05 +/- 1.41 ml.min-1.kg-1, P relationships were found between measures of CYP2E1 activity, both in vivo and in vitro, and genomic polymorphisms in the CYP2E1 gene identified by Rsal/Pstl and Dral restriction fragment length polymorphisms. Collectively, these data show an interracial difference in CYP2E1 activity. Because this enzyme is importantly involved in the activation of environmental procarcinogens, such a difference may account, in part, for the lower rate of some cancers, e.g., lung cancer, in Japanese compared to Caucasians men.

    Full Text Available Objective. Thyrotoxic periodic paralysis (TPP, a known condition in Asian men, is becoming increasingly common in men from Western countries. Since suspicion for TPP as a differential in diagnosis is of utmost importance to avoid overcorrection of hypokalemia and other complications, we are reporting a case of TPP in a 25-year-old Caucasian male. Methods. The patient presented with intermittent lower extremity weakness after consumption of a large high-carbohydrate meal. Clinical examination revealed diffusely enlarged thyroid gland, no muscle power in lower extremities, tremors, and brisk deep tendon reflexes. Results. Clinical and laboratory findings were consistent with Graves’ disease and the patient had hypokalemia. The patient responded to potassium repletion and was treated with propylthiouracil and propranolol. After treatment with radioactive iodine, the patient developed postablative hypothyroidism for which he was treated with levothyroxine. Conclusion. Since this condition is overlooked by physicians in Western countries, we present a case of TPP in a Caucasian male thus showing the importance of consideration of TPP in Caucasians despite its rare occurrence and the need for prompt diagnosis to avoid the danger of hyperkalemia in management of the paralytic attack in TPP patients.

    Full Text Available Abstract Background Cocaine and amphetamine regulated transcript (CART is an anorectic neuropeptide located principally in hypothalamus. CART has been shown to be involved in control of feeding behavior, but a direct relationship with obesity has not been established. The aim of this study was to evaluate the effect of polymorphisms within the CART gene with regards to a possible association with obesity in a Caucasian population. Results Screening of the entire gene as well as a 3.7 kb region of 5' upstream sequence revealed 31 SNPs and 3 rare variants ; 14 of which were subsequently genotyped in 292 French morbidly obese subjects and 368 controls. Haplotype analysis suggested an association with obesity which was found to be mainly due to SNP-3608T>C (rs7379701 (p = 0.009. Genotyping additional cases and controls also of European Caucasian origin supported further this possible association between the CART SNP -3608T>C T allele and obesity (global p-value = 0.0005. Functional studies also suggested that the SNP -3608T>C could modulate nuclear protein binding. Conclusion CART SNP -3608T>C may possibly contribute to the genetic risk for obesity in the Caucasian population. However confirmation of the importance of the role of the CART gene in energy homeostasis and obesity will require investigation and replication in further populations.

    Full Text Available Introduction. 21α-hydroxylase deficiency is the most frequent cause of virilization in patients with female karyotype due to exposure of a female fetus to excess of androgen. We report anatomical and cosmetic results of feminizing genital reconstruction of two related patients (second cousin with XX karyotype born with urogenital sinus anomalies (UGS and not treated at birth. Materials and Metods. Patient 1 is 6-years old with ambiguous genitalia graded as Prader V and never undergone therapy or surgery. Patient 2 is 10-years old, graded as Prader IV and subjected to hormonal therapy and clitoral amputation at the age of 6. Mobilization of urogenital sinus, pull-through of vagina and tubulization of urethra was performed in both after placement of Foley chateters in vagina and bladder by cisto-vaginoscopy. Genitoplasty involved refashioning the tissues to create minora and majora labia and, after removal of corpora, partial clitorectomy was carried in patient 1 and clitoridal reconstruction in patient 2. Result. Vaginal introitus was positioned in the vestibule region below urethral meatus. Foley chateters was removed after two weeks in narcosis and the cosmetic and anatomic result was good. Conclusion. Goals of feminizing genitoplasty are to restore, soon as possible, anatomy achieving a more feminine appareance with a vagina for menstruation, to preserve reproductive capacity and to prevent urological sequelae but it’s also important to contribute in a development of a more stable gender identity. This procedure in two stage, based on an accurate diagnosis, is good to create feminine genital appareance in children with female pseudohermaphroditism expecially if not treated at birth.

    The intravenous (iv) formulation of levetiracetam has been available in clinical practice worldwide for several years, but not in Japan. Two open-label studies were conducted: Study A evaluated the bioequivalence of iv and oral tablet formulations in healthy Japanese volunteers; and Study B subsequently compared the pharmacokinetics of iv levetiracetam in healthy Japanese and Caucasian volunteers. Study A had a randomised, two-way crossover design; a single 1,500 mg levetiracetam dose was administered as a 15-min iv infusion and as 3 × 500 mg oral tablets to Japanese volunteers. In Study B, 1,500 mg levetiracetam was administered as single and repeated 15-min iv infusions to Japanese and Caucasian volunteers. Overall, 26/27 volunteers completed Study A and 32/32 (16 Japanese; 16 Caucasian) completed Study B. In Study A, the point estimate and 90 % confidence interval (CI) for the geometric least squares mean (LSM) ratio (iv vs oral) were fully included within the acceptance range for bioequivalence (0.85-1.25) for the area under plasma concentration-time curve from 0 to last quantifiable observation (AUClast 0.97 [0.95, 0.99]), but not for the maximum plasma concentration (C max 1.64 [1.47, 1.83]). In Study B, after a single iv infusion, the point estimates (90 % CI) for the geometric LSM ratio (Japanese vs Caucasian) for body weight-normalised C max and AUClast were 1.21 (1.07, 1.36) and 0.97 (0.90, 1.04), respectively. Corresponding values after repeated iv infusions were C max,ss 1.01 (0.91, 1.12) and AUCτ,ss 0.89 (0.83, 0.96). Levetiracetam was well tolerated in both studies. Study A did not demonstrate the bioequivalence of single doses of levetiracetam 1,500 mg administered as an iv infusion and as oral tablets in healthy Japanese adults. Study B, however, showed that pharmacokinetic profiles were generally similar between Japanese and Caucasian adults after single and repeated iv infusions of levetiracetam 1,500 mg.

    Molecular genetic studies on Duffy blood group antigens have identified mutations underlying rare FY*Null and FY*X alleles. FY*Null has a high frequency in Blacks, especially from sub-Saharan Africa, while its frequency is not defined in Caucasians. FY*X allele, associated with Fy(a-b+w) phenotype, has a frequency of 2-3.5% in Caucasian people while it is absent in Blacks. During the project of extensive blood group genotyping in patients affected by hemoglobinopathies, we identified FY*X/FY*Null and FY*A/FY*Null genotypes in a Caucasian thalassemic family from Sardinia. We speculate on the frequency of FY*X and FY*Null alleles in Caucasian and Black people; further, we focused on the association of FY*X allele with weak Fyb antigen expression on red blood cells and its identification performing high sensitivity serological typing methods or genotyping.

    Most young Chinese people now learn about Caucasian individuals via media, especially American and European movies and television series (AEMT). The current study aimed to explore whether long-term exposure to AEMT facilitates Caucasian face perception in young Chinese watchers. Before the experiment, we created Chinese, Caucasian, and generic average faces (generic average face was created from both Chinese and Caucasian faces) and tested participants' ability to identify them. In the experiment, we asked AEMT watchers and Chinese movie and television series (CMT) watchers to complete a facial norm detection task. This task was developed recently to detect norms used in facial perception. The results indicated that AEMT watchers coded Caucasian faces relative to a Caucasian face norm better than they did to a generic face norm, whereas no such difference was found among CMT watchers. All watchers coded Chinese faces by referencing a Chinese norm better than they did relative to a generic norm. The results suggested that long-term exposure to AEMT has the same effect as daily other-race face contact in shaping facial perception.

    Full Text Available Background. Our study aimed to assess the burden of depression and evaluate factors associated with depression and status of HIV risk behaviors among female sex workers (FSWs in Guangdong, China. Method. We recruited FSWs from massage parlors, saunas, restaurants, hotels, hair salons, and streets in Guangdong, China, in 2014. Information on demographic characteristics, HIV testing history, and sexual behaviors was collected using a questionnaire. A blood sample was collected to test for HIV, syphilis, and HCV. A participant was defined as being depressed if she obtained 6 points or above using the 12-item General Health Questionnaire. Results. Among the 653 participants, 41.7% were 21–30 years old and 43.6% married. Overall, 52.4% were found to be depressed. FSWs who had correct syphilis related knowledge [aOR = 1.45; 95% CI: 1.04–2.03] and had primary sex partner (1.63, 1.14–2.33 were more likely to be depressed. FSWs who did not use a condom during their last sex with the primary sex partner were less likely to be depressed (0.47, 0.31–0.71. Conclusion. Our study observed high level of depression and HIV risk behaviors among Chinese FSWs. Future interventions should integrate mental health services in comprehensive interventions to prevent depression among Chinese FSWs.

  18. The Caucasian-Arabian segment of the Alpine-Himalayan collisional belt: Geology, volcanism and neotectonics

    E. Sharkov

    2015-07-01

    Full Text Available The Caucasian-Arabian belt is part of the huge late Cenozoic Alpine-Himalayan orogenic belt formed by collision of continental plates. The belt consists of two domains: the Caucasian-Arabian Syntaxis (CAS in the south and the EW-striking Greater Caucasus in the north. The CAS marks a zone of the indentation of the Arabian plate into the southern East European Craton. The Greater Caucasus Range is located in the south of the Eurasian plate; it was tectonically uplifted along the Main Caucasian Fault (MCF, which is, in turn, a part of a megafault extended over a great distance from the Kopetdag Mts. to the Tornquist-Teisseyre Trans-European Suture Zone. The Caucasus Mts. are bounded by the Black Sea from the west and by the Caspian Sea from the east. The SN-striking CAS is characterized by a large geophysical isostatic anomaly suggesting presence of mantle plume head. A 500 km long belt of late Cenozoic volcanism in the CAS extends from the eastern Anatolia to the Lesser and Greater Caucasus ranges. This belt hosts two different types of volcanic rocks: (1 plume-type intraplate basaltic plateaus and (2 suprasubduction-type calc-alkaline and shoshonite-latite volcanic rocks. As the CAS lacks signatures of subduction zones and is characterized by relatively shallow earthquakes (50–60 km, we suggest that the “suprasubduction-type” magmas were derived by interaction between mantle plume head and crustal material. Those hybrid melts were originated under conditions of collision-related deformation. During the late Cenozoic, the width of the CAS reduced to ca. 400 km due to tectonic “diffluence” of crustal material provided by the continuing Arabia-Eurasia collision.

    Full Text Available Background: Underweight as a public health problem in young women is associated with nutritional deficiencies, menstrual irregularity, eating disorders, reduced fertility, etc. Since resting metabolic rate (RMR is a necessary compo-nent in the development of nutrition support therapy, therefore we determined the accuracy of commonly used pre-dictive equations against RMR measured by indirect calorimetry among healthy young underweight females.Methods: This cross-sectional study was conducted on 104 underweight females aged 18-30 years old with body mass index (BMI <18.5 kg/m2 in 2013 . After collecting anthropometric data, body composition was measured by bioelec-tric impedance analysis (BIA. RMR was measured by using indirect calorimetry (FitMate™ and was estimated by 10 commonly used predictive equations. Comparisons were conducted using paired t-test. The accuracy of the RMR equations was evaluated on the basis of the percentage of subjects’ predicted RMR within 10% of measured RMR.Results: The mean BMI of subjects was 17.3±1.3 kg/m2. The measured RMR ranged 736-1490 kcal/day (mean 1084.7±175 kcal/day. Findings indicated that except Muller and Abbreviation, other equations significantly over es-timated RMR, compared to measured value (P<0.05. As an individual prediction accuracy, these predictive equations showed poor performance with the highest accuracy rate of 54.8% for Muller equation (22.1% under and 23.1% over-prediction and 43.3% for Abbreviation equation (31.7% under and 25% over-prediction, the percentage bias was 1.8% and 0.63% and RMSE was 162 and 173 kcal/d, respectively.Conclusion: Although Muller equation gave fairly acceptable prediction, more suitable new equations are needed to be developed to help better management of nutritional plans in young underweight people.

    Unstimulated and chewing-stimulated whole saliva samples were obtained from 42 healthy Caucasians; 21 were between 18 and 35 years of age, and 21 between 65 and 83 years of age. The unstimulated salivary flow rate was significantly lower in the aged group, but the stimulated flow rate was significantly higher in the aged than in the young group. Both groups showed significantly increased flow during salivary stimulation. MG1 and MG2 concentrations in unstimulated and stimulated saliva samples were significantly lower in the aged group. There were no significant correlations between salivary flow rates and MG1 and MG2 concentrations.

    A novel human leucocyte antigen (HLA)-B57 (HLA-B*5714) allele has been identified in a male Caucasian individual from Middle Europe using single allele-specific sequencing strategy. This allele is identical to the HLA-B*570101 allele except for two point mutations in exon 3 at codon 138 (ACG-->ACC) with no amino acid change [persisting threonine (T)] and at codon 171 (TAC-->CAC), resulting in an amino acid change from tyrosine (Y) to histidine (H).

    Full Text Available BACKGROUND: Src, a non-receptor tyrosine kinase is elevated in cancer with expression and activity correlated with cell proliferation, adhesion, survival, motility, metastasis and angiogenesis. There is limited data on Src expression and subcellular localization in breast cancer and no information about expression in racial/ethnic groups. METHODOLOGY/PRINCIPAL FINDINGS: The present study evaluated Src expression, activity, and subcellular localization in triple negative breast cancer (TNBC and ERα positive breast cancer (ER+BC, cancer tissue and adjacent normal epithelial ducts, and Caucasian and African American cases. 79 paraffin embedded breast carcinoma cases were obtained from Tulane University Hospital between 2007-2009. 39 cases represented TNBC (33-African Americans, 4-Caucasians, 2-unknowns and 40 cases represented ER+BC (21-African Americans, 16-Caucasians, 3-unknowns. Immunohistochemistry was used to measure staining distribution and intensity of total Src and activated phospho-SrcY416 (p-Y416Src in carcinoma tissue and adjacent normal mammary ducts. In TNBC and ER+BC, total Src was significantly higher in cancer compared to adjacent normal ducts (P<0.0001 in both cell membrane and cytoplasm. In membranes, p-Y416Src was elevated in cancer compared to normal ducts. Total Src in the tumor cytoplasm was significantly higher in TNBC compared to ER+BC (P = 0.0028; conversely, p-Y416Src in the tumor cell membranes was higher in TNBC compared to ER+BC (P = 0.0106. Comparison between African American (n = 21 and Caucasian ER+BC (n = 16 revealed no significant difference in expression and localization of total Src and p-Y416Src. TNBC cases positive for lymph node metastasis showed elevated membrane p-Y416Src compared to lymph node negative TNBC (P = 0.027. CONCLUSION/SIGNIFICANCE: Total Src and p-Y416Src were expressed higher in cancer compared to adjacent normal ducts. Cytoplasmic total Src and membrane p-Y416Src were

    The N-terminal prohormone B-type natriuretic peptide (NT-proBNP) is a reliable marker of cardiac strain. In hypertensive heart disease, NT-proBNP levels increase and may lose its protective function. Simultaneously, the vasculature is also subject to hemodynamic stress, resulting in vascular matrix...... remodeling and stiffening which contribute to further cardiac alterations. Alkaline phosphatase (ALP) is a marker of osteoblast activity and is involved in vascular calcification. We explored the link between NT-proBNP and ALP in Black and Caucasian African men....

    Cytochrome P450 1B1 (CYP1B1) is involved in the activation of many carcinogens and in the metabolism of steroid hormones. We compared allele, genotype and haplotype frequencies of six single-nucleotide polymorphisms (SNPs) within CYP1B1 among non-Hispanic Caucasians (496 cases and 498 controls) and Hispanic Caucasians (153 cases and 240 controls). In the Hispanic Caucasians, the GG genotype for rs1056836 decreased the risk for prostate cancer (PCa) when compared with the CC genotype [odds ratio (OR) = 0.31, P = 0.04, 95% confidence interval (CI) = 0.10-0.96]. Among non-Hispanic Caucasian men with more aggressive PCa, the prevalence of several SNPs (rs2567206, rs2551188, rs2617266, rs10012 and rs1056836) was significantly associated with the disease status. A common C-G-C-C-G-A haplotype for rs2567206-rs2551188-rs2617266-rs10012-rs1056836-rs1800440 showed an inverse association with PCa risk in Hispanic Caucasians (OR = 0.19, P = 0.04, 95% CI = 0.04-0.95) and with aggressive disease status (i.e. Gleason score >or=7) in non-Hispanic Caucasian cases (OR = 0.64, P = 0.008, 95% CI = 0.47-0.89). In the non-Hispanic Caucasian cases, a second major haplotype T-A-T-G-C-A was positively associated with the high-grade disease status (OR = 1.77, P = 0.002, 95% CI = 1.24-2.53). Our findings suggest that genetic polymorphisms in CYP1B1 may modify the risk for PCa and support the role of CYP1B1 as a candidate gene for PCa.

  8. Asian infants show preference for own-race but not other-race female faces: The role of infant caregiving arrangements

    2015-05-01

    Full Text Available Previous studies have reported that 3- to 4-month-olds show a visual preference for faces of the same gender as their primary caregiver (e.g., Quinn et al., 2002. In addition, this gender preference has been observed for own-race faces, but not for other-race faces (Quinn et al., 2008 However, most of the studies of face gender preference have focused on infants at 3 to 4 months. Development of gender preference in later infancy is still unclear. Moreover, all of these studies were conducted with Caucasian infants from Western countries. It is thus unknown whether a gender preference that is limited to own-race faces can be generalized to infants from other racial groups and different cultures with distinct caregiving practices. The current study investigated the face gender preferences of Asian infants presented with male versus female face pairs from Asian and Caucasian races at 3, 6, and 9 months and the role of caregiving arrangements in eliciting those preferences. The results showed an own-race female face preference in 3- and 6-month-olds, but not in 9-month-olds. Moreover, the downturn in the female face preference correlated with the cumulative male face experience obtained in caregiving practices. In contrast, no gender preference or correlation between gender preference and face experience was found for other-race Caucasian faces at any age. The data indicate that the face gender preference is not specifically rooted in Western cultural caregiving practices. In addition, the race dependency of the effect previously observed for Caucasian infants reared by Caucasian caregivers looking at Caucasian but not Asian faces extends to Asian infants reared by Asian caregivers looking at Asian but not Caucasian faces. The findings also provide additional support for an experiential basis for the gender preference, and in particular suggest that cumulative male face experience plays a role in inducing a downturn in the preference in older

    The purpose of this study is to provide preliminary data for bone disease prevention by examining the correlation between bone mineral density, and lifestyle and nutritional status of female shift workers, at general hospitals with an irregular life cycle. The subjects for this study were 232 female shift workers, over 30 years old, who worked at a general hospital more than 5 years. From the subjects, who understood the purpose of this study and decided to be participated, we measured serum albumin, total protein, total cholesterol, hematocrit, hemoglobin, calcium, phosphorus from blood test, and obtained bone mineral density. To analyze the effectiveness of the variables for explanation power, we established the studied values as independent variables, bone mineral density as a dependent variable. Exercise, the number of drinking, calcium, and phosphorus were selected as significant variables and the explanation power was 10.2%. The bone mineral density were significantly higher at the subjects who had exercise, higher calcium and phosphorus possession, and drank alcohol than the opposite cases. Regular exercise, and 1:1 intake of calcium and phosphorous were important to prevent osteoporosis for the subjects who were working three shifts which cause irregular lifestyle.

    Background Ethnicity is shown to be one of important factors affacting bone mineral density (BMD).The present study was performed to compare the association of six markers for five candidate genes with BMD variation in two populations of different ethnicity, Caucasian and Chinese, and the contribution of genotype and ethnicity to this variation in the populations.Methods The studied restriction fragment length polymorphisms were BsaH Ⅰ of the calcium-sensing receptor gene, SacⅠ of the α2HS-glycoprotein (AHSG) gene, PvuⅡ and XbaⅠ of the oestrogen receptor α gene, ApaⅠ of the vitamin D receptor (VDR) gene and BstBⅠ of the parathyroid hormone gene.The association of these markers with BMD was analysed by one-way and two-way ANOVA with adjustment for covariates.Results Two polymorphisms, AHSG-SacⅠ and VDR-ApaⅠ, showed no association with BMD, while the others were associated with BMD variation at some skeletal sites in either males or females.The polymorphisms indicated clear distinctions between the associations depending on ethnicity, gender and skeletal site.Similar patterns were observed in their contribution to the total population BMD variation.Ethnicity appears to have a larger effect on the total population BMD variation in females than in males.It may account, on the average, for about 2% total population BMD variation at the spine of females and about 1% at the hip of males and females.Conclusion The results of the present study suggest that significant interethnic differentiation at some loci may contribute to the significant interethnic difference in BMD.However, this contribution apparently is not large.

    Aim. To investigate the association between sleep quality and duration with lipid and glycaemic control in Caucasian subjects with type 2 diabetes. Methods. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) in 114 type 2 diabetes (T2DM) subjects. Comparisons were made between subjects with different sleep quality and sleep duration. Hierarchical multiple regression analyses were used to determine contributors to metabolic parameters. Results. Subjects with poor sleep quality (PQ; PSQI ≥ 6) had higher systolic blood pressure, glycated haemoglobin, urine albumin : creatinine ratio (UAC), total cholesterol (TC), and triglycerides (TG) (P < 0.05 for all) compared to those with good sleep quality (GQ; PSQI ≤ 5). Long sleep duration (LSD) subjects had higher TC and short sleep duration (SSD) subjects had higher TG compared to those with medium sleep duration. Sleep duration and PSQI score were independent predictors of TC and low-density lipoprotein cholesterol (LDL), contributing to 14.0% and 6.1% of the total variance, respectively. Conclusions. In this Caucasian T2DM population, PQ is associated with adverse cardiovascular risk markers, and long and short sleep disruptions have an independent negative impact on lipids. Sleep assessment should be included as part of a diabetes clinic review.

    We analyse the effects of the air ambient temperature on the airflow across a Caucasian nasal cavity under different ambient temperatures using CFD simulations. A three-dimensional nasal model was constructed from high-resolution computed tomography images for a nasal cavity from a Caucasian male adult. An exhaustive parametric study was performed to analyse the laminar-compressible flow driven by two different pressure drops between the nostrils and the nasopharynx, which induced calm breathing flow rates ࣈ 5.7 L/min and ࣈ 11.3 L/min. The inlet air temperature covered the range - 10(o) C ⩽ To ⩽50(o) C. We observed that, keeping constant the wall temperature of the nasal cavity at 37(o) C, the ambient temperature affects mainly the airflow velocity into the valve region. Surprisingly, we found an excellent linear relationship between the ambient temperature and the air average temperature reached at different cross sections, independently of the pressure drop applied. Finally, we have also observed that the spatial evolution of the mean temperature data along the nasal cavity can be collapsed for all ambient temperatures analysed with the introduction of suitable dimensionless variables, and this evolution can be modelled with the help of hyperbolic functions, which are based on the heat exchanger theory.

    Full Text Available BACKGROUND: Genome-wide association studies (GWAS in Caucasians have identified fourteen index single nucleotide polymorphisms (iSNPs that influence colorectal cancer (CRC risk. METHODS: We investigated the role of eleven iSNPs or surrogate SNPs (sSNPs, in high linkage disequilibrium (LD, r(2≥ 0.8 and within 100 kb vicinity of iSNPs, in 2,000 age- and gender-matched Singapore Chinese (SCH cases and controls. RESULTS: Only iSNP rs6983267 at 8q24.21 and sSNPs rs6695584, rs11986063, rs3087967, rs2059254, and rs7226855 at 1q41, 8q23.3, 11q23.1, 16q22.1 and 18q21.1 respectively showed evidence of association with CRC risk, with odds ratios (OR ranging from 1.13 to 1.40. sSNP rs827401 at 10p14 was associated with rectal cancer risk (OR = 0.74, 95% CI 0.63-0.88 but not disease prognosis (OR = 0.91, 95% CI 0.69-1.20. Interestingly, sSNP rs3087967 at 11q23.1 was associated with CRC risk in men (OR = 1.34, 95% CI 1.14-1.58 but not women (OR = 1.07, 95% CI: 0.88-1.29, suggesting a gender-specific role. Half of the Caucasian-identified variants, including the recently fine-mapped BMP pathway loci, BMP4, GREM1, BMP2 and LAMA 5, did not show any evidence for association with CRC in SCH (OR ~1; p-value >0.1. Comparing the results of this study with that of the Northern and Hong Kong Chinese, only variants at chromosomes 8q24.21, 10p14, 11q23.1 and 18q21.1 were replicated in at least two out of the three Chinese studies. CONCLUSIONS: The contrasting results between Caucasians and Chinese could be due to different LD patterns and allelic frequencies or genetic heterogeneity. The results suggest that additional common variants contributing to CRC predisposition remained to be identified.

    Clozapine-induced agranulocytosis (CA) is still among the least understood adverse drug reactions in psychopharmacology. In particular, its genetic background is far from being clarified. Within the framework of a case-control study, we performed human leukocyte antigen (HLA) genotyping and haplotype analyses in 42 non-Jewish Caucasian schizophrenic patients (N=42) suffering from CA and 75 non-Jewish Caucasian schizophrenic patients treated with clozapine without developing CA. While controlling for age (Pgenes might play a role, but currently, only HLA associations with CA are identified as clinically relevant.

    The cerebral angiograms of 8 patients with childhood moyamoya disease showed that the common findings were stenosis/occlusion of the supraclinoid internal carotid artery and the proximal segments of the anterior and middle cerebral arteries and basal moyamoya. The volume of basal moyamoya and its collateral supply depended upon the stage of the disease. Leptomeningeal collaterals were frequent in the later stages. Stenotic lesions in the posterior circulation were seen in a majority (75%) of patients. A feature unique to the study was evidence of intracranial small-vessel disease and stenotic cervical internal carotid artery in half of the cases. The disease in the ethnic caucasian Indians seems largely similar to the classical disease frequently reported in the Japanese literature. (orig.).

    Background: A central pattern of fat distribution in postmenopausal women is regarded as a contributor to the increased risk of developing cardiovascular disease.Both ethnicity and occurrence of menopause appear to influence regional fat distribution.However the influence of ethnicity has been under-investigated.Objective: The objective of this study was to test the hypothesis that centralized fat distribution is influenced by ethnic origin.Furthermore, we hypothesize that the menopause-related changes in central adiposity in Caucasian,African-American and Asian women occur at different rates.Method: Total and regional body fat ratios were measured by whole body dual energy X-ray absorptiometry (DXA) in a cross-sectional study using a general linear regression model.After adjustment for age, weight, height,and total body fat, the android and gynoid fat compartments, and the ratio of trunk/leg fat, were analyzed.Results: Four hundred and forty-four women (227 Caucasian (Ca), 128 African-American (AA) and 89 Asian (As)) aged 18-94 y were recruited.Race was significantly (P<0.0001) related to the dependent variables: android and gynoid fat, and ratio of trunk/leg adiposity, in all subjects, adjusted by age, weight, height and total body fat.The interaction of race * menopause was also found to be significant (P=0.028).In each group, regional and total body fat levels, and especially android adiposity, were higher in postmenopausal than in premenopausal women.Interestingly, the postmenopausal difference in android fat in Ca was found significant (P<0.05), whereas such differences had no impact in AA and As subjects (NS).Conclusions: The differences in fat mass and its distribution were racially dependent.The impact of menopause was only significant in Ca group.

    Background Polymorphisms of the peptidylarginine deiminase type 4 (PADI4) gene confer susceptibility to rheumatoid arthritis (RA) in East Asian people. However, studies in European populations have produced conflicting results. This study explored the association of the PADI4 genotype with RA in a large UK Caucasian population. Methods The PADI4_94 (rs2240340) single nucleotide polymorphism (SNP) was directly genotyped in a cohort of unrelated UK Caucasian patients with RA (n=3732) and population controls (n=3039). Imputed data from the Wellcome Trust Case Control Consortium (WTCCC) was used to investigate the association of PADI4_94 with RA in an independent group of RA cases (n=1859) and controls (n=10 599). A further 56 SNPs spanning the PADI4 gene were investigated for association with RA using data from the WTCCC study. Results The PADI4_94 genotype was not associated with RA in either the present cohort or the WTCCC cohort. Combined analysis of all the cases of RA (n=5591) and controls (n=13 638) gave an overall OR of 1.01 (95% CI 0.96 to 1.05, p=0.72). No association with anti-CCP antibodies and no interaction with either shared epitope or PTPN22 was detected. No evidence for association with RA was identified for any of the PADI4 SNPs investigated. Meta-analysis of previously published studies and our data confirmed no significant association between the PADI4_94 genotype and RA in people of European descent (OR 1.06, 95% CI 0.99 to 1.13, p=0.12). Conclusion In the largest study performed to date, the PADI4 genotype was not a significant risk factor for RA in people of European ancestry, in contrast to Asian populations. PMID:19470526

    This study examined racial differences in eating-disorder psychopathology, eating/weight-related histories, and biopsychosocial correlates in women (n = 53 Caucasian and n = 56 African American) with comorbid binge eating disorder (BED) and obesity seeking treatment in primary care settings. Caucasians reported significantly earlier onset of binge eating, dieting, and overweight, and greater number of times dieting than African American. The rate of metabolic syndrome did not differ by race. Caucasians had significantly elevated triglycerides whereas African Americans showed poorer glycaemic control (higher glycated haemoglobin A1c [HbA1c]), and significantly higher diastolic blood pressure. There were no significant racial differences in features of eating disorders, depressive symptoms, or mental and physical health functioning. The clinical presentation of eating-disorder psychopathology and associated psychosocial functioning differed little by race among obese women with BED seeking treatment in primary care settings. Clinicians should assess for and institute appropriate interventions for comorbid BED and obesity in both African American and Caucasian patients.

    Full Text Available Background: The epidemiological evaluation of androgenetic alopecia (AGA is based mainly on direct observation and questionnaires. The international epidemiology and environmental risk factors of AGA in young Caucasian men remain unknown. Aim: To use photographs and data from the Internet to evaluate severe AGA and generate greater understanding of the international epidemiology of the disorder in young Caucasian men. Materials and Methods: A population-based cross-sectional study design was used. The sample included 26,340 Caucasian men aged 30 to 40 years who had uploaded profiles to two dating websites. Their photographs were evaluated for AGA and graded as follows: severe AGA (Norwood type VI-VII, non-severe AGA, and unknown. Epidemiological data were collected from the sites. Logistic regression was used to analyze the effect of risk factors on the prevalence of severe AGA. Results : The overall success rate for identifying severe AGA by indirect evaluation of Internet photographs was 94%. The prevalence of severe AGA was 15.33% overall and varied significantly by geographical region. The risk of having severe AGA was increased by 1.092 for every year of age between 30 and 40 years. Severe AGA was more prevalent in subjects with higher body mass index. Conclusions: Photographs from the Internet can be used to evaluate severe AGA in epidemiological studies. The prevalence of severe AGA in young Caucasian men increases with age and varies by geographical region. Body mass index is an environmental risk factor for severe AGA.

    Full Text Available Olakunle AkinboboyeQueens Heart Institute, Rosedale, NY, USAAbstract: Atrial fibrillation (AF is a very common cardiac arrhythmia, and its prevalence is increasing along with aging in the developed world. This review discusses racial differences in the epidemiology and treatment of AF between African-American and Caucasian patients. Additionally, the effect of race on warfarin and novel oral anticoagulant use is discussed, as well as the role that physicians and patients play in achieving optimal treatment outcomes. Despite having a lower prevalence of AF compared with Caucasians, African-Americans suffer disproportionately from stroke and its sequelae. The possible reasons for this paradox include poorer access to health care, lower health literacy, and a higher prevalence of other stroke-risk factors among African-Americans. Consequently, it is important for providers to evaluate the effects of race, health literacy, access to health care, and cultural barriers on the use of anticoagulation in the management of AF. Warfarin-dose requirements vary across racial groups, with African-American patients requiring a higher dose than Caucasians to maintain a therapeutic international normalized ratio; the novel oral anticoagulants (dabigatran, rivaroxaban, and apixaban seem to differ in this regard, although data are currently limited. Minority racial groups are not proportionally represented in either real-world studies or clinical trials, but as more information becomes available and other social issues are addressed, the treatment disparities between African-American and Caucasian patients should decrease.Keywords: antithrombotic, atrial fibrillation, stroke, warfarin, race

    A central claim of cultural neuroscience is that the culture to which an individual belongs plays a key role in shaping basic cognitive processes and behaviours, including eye movement behaviour. We previously reported a robust difference in saccade behaviour between Chinese and Caucasian participants; Chinese participants are much more likely to execute low latency express saccades, in circumstances in which these are normally discouraged. To assess the extent to which this is the product of culture we compared a group of 70 Chinese overseas students (whose primary cultural exposure was that of mainland China), a group of 45 participants whose parents were Chinese but who themselves were brought up in the UK (whose primary cultural exposure was western European) and a group of 70 Caucasian participants. Results from the Schwartz Value Survey confirmed that the UK-Chinese group were culturally similar to the Caucasian group. However, their patterns of saccade latency were identical to the mainland Chinese group, and different to the Caucasian group. We conclude that at least for the relatively simple reflexive saccade behaviour we have investigated, culture cannot explain the observed differences in behaviour.

    The detection of misuse with naturally occurring steroids is a great challenge for doping control laboratories. Intake of natural anabolic steroids alters the steroid profile. Thus, screening for exogenous use of these steroids can be established by monitoring a range of endogenous steroids, which constitute the steroid profile, and evaluate their concentrations and ratios against reference ranges. Elevated values of the steroid profile constitute an atypical finding after which a confirmatory IRMS procedure is needed to unequivocally establish the exogenous origin of a natural steroid. However, the large inter-individual differences in urinary steroid concentrations and the recent availability of a whole range of natural steroids (e.g. dehydroepiandrosterone and androstenedione) which each exert a different effect on the monitored parameters in doping control complicate the interpretation of the current steroid profile. The screening of an extended steroid profile can provide additional parameters to support the atypical findings and can give specific information upon the steroids which have been administered. The natural concentrations of 29 endogenous steroids and 11 ratios in a predominantly Caucasian population of athletes were determined. The upper reference values at 97.5%, 99% and 99.9% levels were assessed for male (n=2027) and female (n=1004) populations. Monitoring minor metabolites and evaluation of concentration ratios with respect to their natural abundances could improve the interpretation of the steroid profile in doping analysis.

    The aim of this study was to evaluate the association between cervical posture on lateral skull radiographs and surface electromyographic recordings (sEMG) of head and neck muscles. The sample comprised 40 Caucasian adult females, average age 26.8 (20-48); lateral skull radiographs were obtained in natural head position (mirror position). sEMG activity was bilaterally investigated for the following muscles: masseter, anterior temporalis, digastric, posterior cervical, sternocleidomastoid and upper and lower trapezius. All muscles were monitored at rest and during maximal voluntary clenching (MVC). A Pearson's correlation coefficient revealed significant correlations (P cervical angulations and sEMG activity of masseter, digastric, lower trapezius, during MVC and anterior temporalis at rest. Significant correlations (P cervical lordosis angle and sEMG activity of masseter (during MVC) and lower trapezius (at rest). In view of transversal method, no conclusion was possible about the mechanism concerning these results. Future longitudinal studies should be directed to understand the extent of environmental and genotype influences by masticatory muscle activity on cervical posture.

    Full Text Available Abstract Background Since scarce data exist on the pathogenesis of nasopharyngeal carcinoma in Caucasian patients, we attempted to elucidate the responsible molecular pathways in this patient population. Methods Formalin-fixed paraffin-embedded tumor tissue samples from 107 patients, diagnosed with locally-advanced nasopharyngeal carcinoma and treated with chemotherapy or chemo-radiotherapy, were analyzed by immunohistochemistry for the expression of the following proteins: E-cadherin, P-cadherin, Fascin-1, Cyclin D1, COX-2, EGFR, VEGF-A, VEGF-C, VEGFR-2, VEGFR-3, ERCC1, p53, p63, Ki67, MAPT, phospho-p44/42MAPK, PTEN, phospho-AKT, phospho-mTOR, and phospho-GSK-3β. EBER status was assessed by in situ hybridization. The majority of the cases were included in tissue microarray. All stains were performed and assessed centrally by two pathologists. The median follow-up time was 76.8 (42.3 – 99.2 months. Results Biomolecules expressed in >90% of cases were: p53, COX-2, P-cadherin, EBER, phospho-GSK-3β, and Fascin-1. WHO II+III tumors were more frequently EBER & PTEN positive and VEGF-A negative. Advanced age was significantly associated with positive phospho-GSK-3β and ERCC1 expression; male gender with positive phospho-AKT and phospho-p44/42MAPK; and worse performance status (1 or 2 with negative Ki67, ERCC1, PTEN, and phospho-mTOR expression. Earlier disease stage was closely associated with p63, MAPT, PTEN, and Cyclin D1 positivity. Univariate Cox regression analysis highlighted Cyclin D1 as a negative prognostic factor for disease-free survival (p=0.034 and EBER as a positive one for overall survival (p=0.048. In multivariate analysis, advanced age and stage, poor performance status, and positive ERCC1 emerged as predictors of worse disease-free and overall survival, as opposed to positive phospho-mTOR. Clustering analysis defined two protein-expression groups being predictive of better overall survival (p=0.043. Conclusions Our study is the

    Three distinct mitochondrial maternal lineages (haplotype Groups A, B, and C) have been found in the domestic sheep. Group B has been observed primarily in European domestic sheep. The European mouflon carries this haplotype group. This could suggest that European mouflon was independently domesticated in Europe, although archaeological evidence supports sheep domestication in the central part of the Fertile Crescent. To investigate this question, we sequenced a highly variable segment of mitochondrial DNA (mtDNA) in 406 unrelated animals from 48 breeds or local varieties. They originated from a wide area spanning northern Europe and the Balkans to the Altay Mountains in south Siberia. The sample included a representative cross-section of sheep breeds from areas close to the postulated Near Eastern domestication center and breeds from more distant northern areas. Four (A, B, C, and D) highly diverged sheep lineages were observed in Caucasus, 3 (A, B and C) in Central Asia, and 2 (A and B) in the eastern fringe of Europe, which included the area north and west of the Black Sea and the Ural Mountains. Only one example of Group D was detected. The other haplotype groups demonstrated signs of population expansion. Sequence variation within the lineages implied Group A to have expanded first. This group was the most frequent type only in Caucasian and Central Asian breeds. Expansion of Group C appeared most recently. The expansion of Group B involving Caucasian sheep took place at nearly the same time as the expansion of Group A. Group B expansion for the eastern European area started approximately 3,000 years after the earliest inferred expansion. An independent European domestication of sheep is unlikely. The distribution of Group A variation as well as other results are compatible with the Near East being the domestication site. Groups C and D may have been introgressed later into a domestic stock, but larger samples are needed to infer their geographical origin. The

    A 5-day High-Fat High-Calorie diet (HFHC-diet) reduces insulin-stimulated glucose disposal (Rd) in South Asian, but not Caucasian healthy lean males. We aimed to investigate if differences in myocellular lipid handling are underlying this differential response. A two-step hyperinsulinemic-euglycemic clamp and muscle biopsies were performed in 12 healthy lean Caucasian and South Asian males (BMI < 25 kg/m2, 19–25 years) before and after a 5-day HFHC-diet (regular diet + 375 mL cream/day; 1275 kcal/day; 94% fat). Triglyceride extractions and Western Blots for lipid droplet and mitochondrial proteins were performed. Intramyocellular lipid content and HFHC-diet response were similar between ethnicities (group effect: P = 0.094; diet effect: +~30%, P = 0.044). PLIN5 protein content increased upon the HFHC-diet (P = 0.031) and tended to be higher in South Asians (0.87 ± 0.42 AU vs. 1.35 ± 0.58 AU, P = 0.07). 4-HNE tended to increase in South Asians upon the HFHC-diet (interaction effect: P = 0.057). In Caucasians ΔPLIN5 content correlated with ΔRd (Caucasians: r = 0.756, P = 0.011; South Asians: r = −0.085, P = 0.816), while in South Asians Δ4-HNE associated with ΔPLIN5 content (Caucasians: r = 0.312, P = 0.380; South Asians: r = 0.771, P = 0.003). These data indicate that in Caucasians, PLIN5 may be protective against HFHC-diet induced insulin resistance, which for reasons not yet understood is not observed in South Asians, who possess increased lipid peroxidation levels.

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundant fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy's Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities. Native Americans were less concerned with distance from home for consumptive/non-consumptive activities, compared to religious

    Full Text Available This study was undertaken to clarify the molecular basis for human skin color variation and the environmental adaptability to ultraviolet irradiation, with the ultimate goal of predicting the impact of changes in future environments on human health risk. One hundred twenty-two Caucasians living in Toledo, Ohio participated. Back and cheek skin were assayed for melanin as a quantitative trait marker. Buccal cell samples were collected and used for DNA extraction. DNA was used for SNP genotyping using the Masscode™ system, which entails two-step PCR amplification and a platform chemistry which allows cleavable mass spectrometry tags. The results show gene-gene interaction between SNP alleles at multiple loci (not necessarily on the same chromosome contributes to inter-individual skin color variation while suggesting a high probability of linkage disequilibrium. Confirmation of these findings requires further study with other ethic groups to analyze the associations between SNP alleles at multiple loci and human skin color variation. Our overarching goal is to use remote sensing data to clarify the interaction between atmospheric environments and SNP allelic frequency and investigate human adaptability to ultraviolet irradiation. Such information should greatly assist in the prediction of the health effects of future environmental changes such as ozone depletion and increased ultraviolet exposure. If such health effects are to some extent predictable, it might be possible to prepare for such changes in advance and thus reduce the extent of their impact.

    AIM: To investigate the association between epidermal growth factor (EGF ) +61A/G polymorphism and susceptibility to gastric cancer, through a cross-sectional study. METHODS: Polymerase chain reaction resctriction fragment lenght polymorphism analyses were used to genotype EGF +61 in 207 patients with gastric lesions (162 patients with gastric adenocarcinomas, 45 with atrophy or intestinal metaplasia) and 984 controls. All subjects were Caucasian. RESULTS: Genotype distribution was 23.5% for GG and 76.5% for GA/AA in the control group, 18.4% for GG and 68.6% for GA/AA in the entire group with gastric lesions and 17.9% for GG and 82.1% for GA/AA in the group with gastric adenocarcinoma. No statistically significant associations were found between EGF +61 variants and risk for developing gastric cancer [odds ratios (OR) = 1.41, 95% confidence intervals (CI): 0.90-2.21, P = 0.116]. However, the stratification of individuals by gender revealed that males carrying A alleles (EGF +61A/G or AA) had an increased risk for developing gastric cancer as compared to GG homozygous males (OR = 1.55, 95% CI: 1.05-2.28, P = 0.021). CONCLUSION: In summary, we found that males who were A carriers for EGF +61 had an increased risk for developing gastric cancer. This result may be explained by the suggestion that women secrete less gastric acid than men.

    Full Text Available Abstract Background Despite intensive study of high-risk mucosal human papillomaviruses (HPV, little is known of the epidemiology of cutaneous HPV. As part of a study of cutaneous squamous cell carcinoma and HPV among organ transplant recipients (OTR from London and Oxford, we investigated the seroprevalence and risk factors for 34 HPV types (detected using Luminex technology among 425 Caucasian OTR without skin cancer. Results Overall, 86% of participants were seropositive to at least one HPV: 41% to mucosal alpha types, 33% to cutaneous alpha types, 57% to alpha types, 56% to beta, 47% to gamma types and 45% to other types (nu, mu, HPV101 and 103. In both centres, the most common types were HPV6 (33% and 26% for London and Oxford respectively, HPV8 (24% and 18%, HPV15 (26% and 29%, HPV17 (25% and 21%, HPV38 (23% and 21%, HPV49 (19% and 21%, HPV4 (27% and 23%, HPV65 (30% and 25%, HPV95 (22% and 20%, HPV1 (33% and 24% and HPV63 (28% and 17%. The seroprevalence of 8 HPV types differed significantly (P Conclusion Findings for mucosal HPV types were in line with results from previous studies. We observed differences in HPV seroprevalence between organ transplant recipients from two geographically close centres but no clear risk factor was found associated with cutaneous HPV seropositivity among organ transplant recipients. These findings have implications for interpretation of future seroepidemiology studies addressing the association between HPV and cutaneous SCC in OTR populations.

    Objective: The aim of the study was to investigate in postmenopausal women whether the relationship between percentage body fat (PBF) and body mass index (BMI) differs between Asians living in Beijing (BA) and African-Americans (AA), and Caucasians (Ca) living in New York City.Methods: Healthy postmenopausal women (231 BA; 113 AA, 95 Ca), aged 50-80 years, were studied. Weight, height and PBF by dual energy X-ray absorptiometry (DXA) were measured. The relationship between PBF and BMI was assessed by multiple regression analysis. Results: Race, reciprocal of BMI (1/BMI) and the interaction between race and 1/BMI were all significantly (P<0.05) related to PBF in this sample. The slope of the line relating 1/BMI to PBF was different for BA compared to AA (P=0.01) and Ca (P=0.003) while the slopes for AA and Ca were not different (P>0.05). At lower levels of BMI, Asians tended to have higher PBF comparable to AA and Ca, while at BMI >30 BA tended to have less PBF than the other groups. Conclusion: The relation between PBF and BMI in BA postmenopausal women differs from that of AA and Ca women in this sample.

    Background and study aims: Better endoscopic diagnosis in case of Barrett’s esophagus is still needed. White globe appearance (WGA) is a novel endoscopic marker for gastric adenocarcinoma, with high sensitivity for differentiating between gastric cancer/high-grade dysplasia and other lesions. We report 2 cases of esophageal adenocarcinoma with WGA. In Case 1, esophagogastroduodenoscopy (EGD) revealed a 10-mm esophageal adenocarcinoma in a 48-year-old Japanese woman with short-segment Barrett’s esophagus. A small (< 1 mm) white globular lesion, typical of WGA, was observed under the epithelium by magnifying narrow-band imaging. A dilated neoplastic gland with eosinophilic material and necrotic epithelial fragments was identified at the site of the WGA by histologic examination. In Case 2, EGD revealed a 5-mm esophageal adenocarcinoma in a 60-year-old Caucasian man with long-segment Barrett’s esophagus. A typical WGA was observed by magnifying narrow-band imaging and similar histologic findings were identified at the site of the WGA. WGA could be a reliable endoscopic finding for target biopsy in esophageal adenocarcinoma, if its specificity is as high as in gastric cancer. The clinical implications of WGA in patients with Barrett’s esophagus should be investigated further. PMID:27747281

    Intraventricular hemorrhage during pregnancy is usually followed by a poor recovery. When caused by moyamoya disease, ischemic or hemorrhagic episodes may complicate the management of high intracranial pressure. A 26-year-old Caucasian woman presented with generalized seizures and a Glasgow Coma Score (GCS) of 3 during the 36th week of pregnancy. The fetus was delivered by caesarean section. The brain CT in the mother revealed bilateral intraventricular hemorrhage, a callosal hematoma, hydrocephalus and right frontal ischemia. Refractory high intracranial pressure developed and required bilateral ventricular drainage and intensive care treatment with barbiturates and hypothermia. Magnetic resonance imaging and cerebral angiography revealed a moyamoya syndrome with rupture of the abnormal collateral vascular network as the cause of the hemorrhage. Intracranial pressure could only be controlled after the surgical removal of the clots after a large opening of the right ventricle. Despite an initially low GCS, this patient made a good functional recovery at one year follow-up. Management of refractory high intracranial pressure following moyamoya related intraventricular bleeding should require optimal removal of ventricular clots and appropriate control of cerebral hemodynamics to avoid ischemic or hemorrhagic complications.

    Full Text Available Abstract Introduction Most gastric tumors are adenocarcinomas. Primary gastric adenosquamous carcinoma is a rare malignancy, mostly associated with Asian populations. It constitutes less than one percent of all gastric carcinomas and its clinical presentation is the same as adenocarcinoma. It occurs more frequently in the proximal stomach, usually presents with muscular layer invasion and tends to be found in advanced stages at diagnosis, with a worse prognosis than adenocarcinoma. Case presentation We report the case of an 84-year-old Caucasian woman with an adenosquamous carcinoma extending to her serosa with lymphatic and venous invasion (T3N1M1. Nodal and hepatic metastasis presented with both cellular types, with dominance of the squamous component. Conclusions Adenosquamous gastric cancer is a rare diagnosis in western populations. We present the case of a woman with a very aggressive adenosquamous carcinoma with a preponderance of squamous cell component in the metastasis. Several origins have been proposed for this kind of carcinoma; either evolution from adenocarcinoma de-differentiation or stem cell origin might be possible. The hypothesis that a particular histological type of gastric cancer may arise from stem cells might be a field of research in oncological disease of the stomach.

    The purpose of this study was to examine the factor structure, reliability, and validity of the Family Assessment Device (FAD) among a national sample of Caucasian and Hispanic American families receiving public sector mental health services. A confirmatory factor analysis conducted to test model fit yielded equivocal findings. With few exceptions, indices of model fit, reliability, and validity were poorer for Hispanic Americans compared with Caucasian Americans. Contrary to our expectation, an exploratory factor analysis did not result in a better fitting model of family functioning. Without stronger evidence supporting a reformulation of the FAD, we recommend against such a course of action. Findings highlight the need for additional research on the role of culture in measurement of family functioning.

  12. Valuation of environmental quality and eco-cultural attributes in Northwestern Idaho: Native Americans are more concerned than Caucasians.

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundant fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy's Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities. Native Americans were less concerned with distance from home for consumptive/non-consumptive activities, compared to religious

    Leber hereditary optic neuropathy (LHON) is a type of blindness caused by mtDNA mutations. Three LHON mtDNA mutations at nucleotide positions 3460, 11778, and 14484 are specific for LHON and account for 90% of worldwide cases and are thus designated as {open_quotes}primary{close_quotes} LHON mutations. Fifteen other {open_quotes}secondary{close_quotes} LHON mtDNA mutations have been identified, but their pathogenicity is unclear. mtDNA haplotype and phylogenetic analysis of the primary LHON mutations in North American Caucasian patients and controls has shown that, unlike the 3460 and 11778 mutations, which are distributed throughout the European-derived (Caucasian) mtDNA phylogeny, patients containing the 14484 mutation tended to be associated with European mtDNA haplotype J. To investigate this apparent clustering, we performed {chi}{sup 2}-based statistical analyses to compare the distribution of LHON patients on the Caucasian phylogenetic tree. Our results indicate that, unlike the 3460 and 11778 mutations, the 14484 mutation was not distributed on the phylogeny in proportion to the frequencies of the major Caucasian mtDNA haplogroups found in North America. The 14484 mutation was next shown to occur on the haplogroup J background more frequently that expected, consistent with the observation that {approximately}75% of worldwide 14484-positive LHON patients occur in association with haplogroup J. The 11778 mutation also exhibited a moderate clustering on haplogroup J. These observations were supported by statistical analysis using all available mutation frequencies reported in the literature. This paper thus illustrates the potential importance of genetic background in certain mtDNA-based diseases, speculates on a pathogenic role for a subset of LHON secondary mutations and their interaction with primary mutations, and provides support for a polygenic model for LHON expression in some cases. 18 refs., 3 tabs.

  14. Pneumatization of the sphenoid sinus in Chinese: the differences from Caucasian and its application in the extended transsphenoidal approach.

    In recent years, the transsphenoidal approach has been extensively used surgically to treat parasellar, suprasellar, clival, and even petrous lesions. Extended pneumatization of the sphenoid sinus (SS) is considered an indispensable element for the extended transsphenoidal (ETS) approach. Because most anatomical studies of the ETS approach use Caucasian subjects, the present study aims to clarify the pneumatic extension types in Chinese individuals as well as any differences from those in Caucasians and analyze these differences with respect to the application of the ETS approach. A total of 200 computed tomography (CT) images of SSs and 18 adult cadaveric heads were selected for observation and measurement. The conchal, presellar, and sellar types comprised 6, 28.5, and 65.5% of subjects, respectively; according to the extra extension, the prevalence of the lateral, clival, lesser wing, and combined extension sinus types was 11.4, 21.4, 0.8, and 48.1% of subjects, respectively. The percentages of pneumatization of the anterior and posterior clinoid processes, pterygoid process, and optic strut were 5.0, 1.0, 22.3, and 7.0%, respectively. Onodi cells were observed in 61.1% of the sides of the cadaveric heads, including 30.6% with good pneumatization with identifiable optical or ICA bulges. These features were related to poor lateral and clival gasification in Chinese compared with Caucasians, which might make extended surgery more dangerous. However, the anterior pneumatization, especially the higher presentation of Onodi cells, ensures that the anterior ETS approach can be performed safely in Chinese patients. In general, measurements showing smaller sinus volumes and thicker bones with identifiable bone landmarks that are hard to find compared with those in Caucasians suggest increased surgical risks in the Chinese population. In this situation, carefully analysis of presurgical CT and magnetic resonance imaging scans is important. Furthermore, in the ETS

From different characterization tests (chemical, physical, and micro structural), it can be conclude that the concrete is not showing any pathology and any important attack, due to the marine environment. After being exposed during 30 years, the chlorides ions have not reach the steel metal bar reinforcement and the carbonation depth is still low.

    A theoretical framework, which included perspectives of individualism-collectivism and self-efficacy, was used to investigate factors associated with sexual risk practice among gay Asian and Caucasian men. "Risk" was defined as unprotected anal intercourse with any casual partner or with a regular partner whose HIV status was not concordant with the participant's. Altogether, 201 Caucasian and 199 Asian gay men, largely recruited from gay social venues in inner Sydney, completed an anonymous questionnaire. Most participants were gay self-identified and gay community attached, and more than half of the Asian men had been living in Sydney for at least 3 years. Overall, the Asian men were more collectivist oriented and the Caucasian men more individualist oriented. Data analyses revealed that higher self-efficacy in avoiding casual risk encounters and smaller proportion of gay friends were associated with less risk. The inclusion of individualism-collectivism and social cognitive variables in the examination of sexual risk practices among gay men from different cultural backgrounds holds promise.

    Multiple sclerosis (MS) is a demyelinating disease in the central nervous system. Genetics have been considered as a leading factor in the prevalence and disease course of MS. We have presented an informatics-based eFolder system for integrating patients' clinical data with MR images and lesion quantification results. The completed eFolder system has been designed and developed in aiding to evaluate disease manifestation differences in Hispanic and Caucasian MS patients. MS lesion data, as shown in MRI, can be extracted by the 3-D automatic lesion detection tool in the eFolder, and data storing and mining tools in eFolder is able to extract and compare data from individual patients. The computer-aided detection (CAD) algorithm has been modified and enhanced to include spatial information as detection criteria. For this study, 36 Caucasian MS patients and 36 matched Hispanic patients have been selected. Most recent MR images of the patients are collected, and images are evaluated both by the CAD tool in the eFolder and radiologists. The results are compared between Caucasian and Hispanic patients and statistically evaluated to see if the two populations have significant difference in lesion presentations. The results can be used to evaluate differences in the two groups of patients and to evaluate the new CAD algorithm's performance with radiologists' contours. Significant findings can further evaluate effectiveness of MS eFolder in MS-related research.

  19. East meets West: ethnic differences in epidemiology and clinical behaviors of lung cancer between East Asians and Caucasians

    Lung cancer is the leading cause of cancer death worldwide, with large variation of the incidence and mortality across regions. Although the mortality of lung cancer has been decreasing, or steady in lhe US, it has been increasing in Asia for the past two decades. Smoking is the leading cause of lung cancer, and other risk factors such as indoor coal buming, cooking fumes, and infections may play important roles in the development of lung cancer among Asian never smoking women. The median age of diagnosis in Asian patients with lung cancer is generally younger than Caucasian patients, particularly among never smokers. Asians and Caucasians may have different genetic susceptibilities to lung cancer, as evidenced from candidate polymorphisms and genome-wide association studies. Recent epidemiologic studies and clinical trials have shown consistently that Asian ethnicity is a favorable prognostic factor for overall survival in non-small cell lung cancer (NSCLC), independent of smoking status. Compared with Caucasian patients with NSCLC, East Asian patients have a much higher prevalence of epidermal growth factor receptor (EGFR) mutation (approximately 30% vs. 7%, predominantly among patients with adenocarcinoma and never-smokers), a lower prevalence of K-Ras mutation (less than 10% vs. 18%, predominantly among patients with adenocarcinoma and smokers), and higher proportion of patients who are responsive to EGFR tyrosine kinase inhibitors. The ethnic differences in epidemiology and clinical behaviors should be taken into account when conducting global clinical trials that include different ethnic populations.

    Objective:To understand whether reduced pregnancy and live birth rates for Asian patients undergoing in vitro fertilization (IVF) could be explained by discrepant rates of aneuploid embryos.Methods:A retrospective cohort study of all autologous and donor IVF cycles utilizing pre-implantation genetic screening (PGS) at a single infertility clinic from January 2012 to December 2013.Results:After controlling for maternal age, there was no difference in aneuploidy rates of Caucasian patients compared to Asian patients’. A trend was discerned that embryos of Caucasians form blastocysts more frequently than those of Asian patients, reaching significance for patients aged 25 to 30 and 40 to 45, but there was no difference in the likelihood of having at least one euploid blastocyst to transfer in any age group. Conclusion:While there may be a slight difference in blastocyst formation rates, there is no difference in aneuploidy or euploid blastocyst transfer rates between Asian and Caucasian patients that would explain the discrepancy in IVF outcomes observed between these patient populations. Possible ethnicity specific differences in non-ploidy related embryo viability and endometrial receptivity should be investigated as potential etiologies for this observation.

    Background Reference values for morphological and functional parameters of the cardiovascular system in early life are relevant since they may help to identify young adults who fall outside the physiological range of arterial and cardiac ageing. This study provides age and sex specific reference values for aortic wall characteristics, cardiac function parameters and aortic pulse wave velocity (PWV) in a population-based sample of healthy, young adults using magnetic resonance (MR) imaging. Materials and Methods In 131 randomly selected healthy, young adults aged between 25 and 35 years (mean age 31.8 years, 63 men) of the general-population based Atherosclerosis-Monitoring-and-Biomarker-measurements-In-The-YOuNg (AMBITYON) study, descending thoracic aortic dimensions and wall thickness, thoracic aortic PWV and cardiac function parameters were measured using a 3.0T MR-system. Age and sex specific reference values were generated using dedicated software. Differences in reference values between two age groups (25–30 and 30–35 years) and both sexes were tested. Results Aortic diameters and areas were higher in the older age group (all p<0.007). Moreover, aortic dimensions, left ventricular mass, left and right ventricular volumes and cardiac output were lower in women than in men (all p<0.001). For mean and maximum aortic wall thickness, left and right ejection fraction and aortic PWV we did not observe a significant age or sex effect. Conclusion This study provides age and sex specific reference values for cardiovascular MR parameters in healthy, young Caucasian adults. These may aid in MR guided pre-clinical identification of young adults who fall outside the physiological range of arterial and cardiac ageing. PMID:27732640

    Prostate cancer is the most prevalent cancer in males in Western countries.The reported incidence in Asia is much lower than that in African Americans and European Caucasians.Although the lack of systematic prostate cancer screening system in Asian countries explains part of the difference,this alone cannot fully explain the-lower incidence in Asian immigrants in the United States and west-European countries compared to the black and non-Hispanic white in those countries,nor the somewhat better prognosis in Asian immigrants with prostate cancer in the United States.Soy food consumption,more popular in Asian populations,is associated with a 25% to 30% reduced risk of prostate cancer.Prostatespecific antigen(PSA) is the only established and routinely implemented clinical biomarker for prostate cancer detection and disease status.Other biomarkers,such as urinary prostate cancer antigen 3 RNA,may increase accuracy of prostate cancer screening compared to PSA alone.Several susceptible loci have been identified in genetic linkage analyses in populations of countries in the West,and approximately 30 genetic polymorphisms have been reported to modestly increase the prostate cancer risk in genomewide association studies.Most of the identified polymorphisms are reproducible regardless of ethnicity.Somatic mutations in the genomes of prostate tumors have been repeatedly reported to include deletion and gain of the 8p and 8q chromosomal regions,respectively; epigenetic gene silencing of glutathione Stransferase Pi (GSTP1); as well as mutations in androgen receptor gene.However,the molecular mechanisms underlying carcinogenesis,aggressiveness,and prognosis of prostate cancer remain largely unknown.Gene-gene and/or gene-environment interactions still need to be learned.In this review,the differences in PSA screening practice,reported incidence and prognosis of prostate cancer,and genetic factors between the populations in East and West factors are discussed.

    2016-01-01

    Summary Lipoid congenital adrenal hyperplasia (lipoid CAH), the most severe form of CAH, is most commonly caused by mutations in steroidogenic acute regulatory protein (STAR), which is required for the movement of cholesterol from the outer to the inner mitochondrial membranes to synthesize pregnenolone. This study was performed to evaluate whether the salt-losing crisis and the adrenal inactivity experienced by a Scandinavian infant is due to a de novo STAR mutation. The study was conducted at the University of North Dakota, the Mercer University School of Medicine and the Memorial University Medical Center to identify the cause of this disease. The patient was admitted to a pediatric endocrinologist at the Sanford Health Center for salt-losing crisis and possible adrenal failure. Lipoid CAH is an autosomal recessive disease, we identified two de novo heterozygous mutations (STAR c.444C>A (STAR p.N148K) and STAR c.557C>T (STAR p.R193X)) in the STAR gene, causing lipoid CAH. New onset lipoid CAH can occur through de novo mutations and is not restricted to any specific region of the world. This Scandinavian family was of Norwegian descent and had lipoid CAH due to a mutation in S TAR exons 4 and 5. Overexpression of the STAR p.N148K mutant in nonsteroidogenic COS-1 cells supplemented with an electron transport system showed activity similar to the background level, which was ∼10% of that observed with wild-type (WT) STAR. Protein-folding analysis showed that the finger printing of the STAR p.N148K mutant is also different from the WT protein. Inherited STAR mutations may be more prevalent in some geographical areas but not necessarily restricted to those regions. Learning points STAR mutations cause lipoid CAH.This is a pure population from a caucasian family.Mutation ablated STAR activity.The mutation resulted in loosely folded conformation of STAR.

    This review provides an overview of the literature on aspects of reproductive endocrinology wherein Asian men may differ from Caucasian, notably, prostatic nioplasm and the sensivity to pharmacological regimens of male contraception. Both genetic and environmental factors, such as nutrition, might be relevant. Asian men residing in Asia seem to be relatively protected from clinical prostatic nioplasm while the prevalence of preclinical prostatic nioplasm is not different. Migration to an area with a higher prevalence reduces this difference but does not undo it. With regard to prostatic nioplasm the following factors have been considered as relevant in Asian men: 1) a reduction in 5α-reductase level, 2) decreased levels of androgenic ketosteroid precursors of 5α-reduced androgen metabolites, 3) the decreased presence of a P53 mutation, 4) a higher CAG-repeat length of the androgen receptor, 5) a possible higher level of physical activity, 6) differences in sexual activity. Furthermore, Asian men respond to a higher degree with azoospermia in response to contraceptive steroids. Possible explanations offered for the more pronounced response to contraceptive steroids are: 1) differences in testicular structure and decreased spermatogenic potential, 2) an earlier and more marked suppression in LH secretion by exogenous androgens. The differences may be due to genetical and/or environmental factors influencing the peripheral testosterone metabolism. Dietary factors such as the higher intake of phytoestrogens in Asians might exert effects on 5α-reductase activity and/or on sex hormone binding globulin (SHBG) levels,thus having an impact on the biological efficay of circulating androgens.

    Full Text Available Recently an association was demonstrated between the single nucleotide polymorphism (SNP, rs9939609, within the FTO locus and obesity as a consequence of a genome wide association (GWA study of type 2 diabetes in adults. We examined the effects of two perfect surrogates for this SNP plus 11 other SNPs at this locus with respect to our childhood obesity cohort, consisting of both Caucasians and African Americans (AA. Utilizing data from our ongoing GWA study in our cohort of 418 Caucasian obese children (BMI>or=95th percentile, 2,270 Caucasian controls (BMI<95th percentile, 578 AA obese children and 1,424 AA controls, we investigated the association of the previously reported variation at the FTO locus with the childhood form of this disease in both ethnicities. The minor allele frequencies (MAF of rs8050136 and rs3751812 (perfect surrogates for rs9939609 i.e. both r(2 = 1 in the Caucasian cases were 0.448 and 0.443 respectively while they were 0.391 and 0.386 in Caucasian controls respectively, yielding for both an odds ratio (OR of 1.27 (95% CI 1.08-1.47; P = 0.0022. Furthermore, the MAFs of rs8050136 and rs3751812 in the AA cases were 0.449 and 0.115 respectively while they were 0.436 and 0.090 in AA controls respectively, yielding an OR of 1.05 (95% CI 0.91-1.21; P = 0.49 and of 1.31 (95% CI 1.050-1.643; P = 0.017 respectively. Investigating all 13 SNPs present on the Illumina HumanHap550 BeadChip in this region of linkage disequilibrium, rs3751812 was the only SNP conferring significant risk in AA. We have therefore replicated and refined the association in an AA cohort and distilled a tag-SNP, rs3751812, which captures the ancestral origin of the actual mutation. As such, variants in the FTO gene confer a similar magnitude of risk of obesity to children as to their adult counterparts and appear to have a global impact.

    2004-08-01

    Full Text Available Abstract Background Individuals with coronary artery disease are at high risk for adverse health outcomes. This risk can be diminished by aggressive lipid management, but adherence to lipid management guidelines is far from ideal and substantial racial disparities in care have been reported. Lipid treatment and goal attainment information is not readily available for large patient populations seen in the fee-for-service setting. As a result, national programs to improve lipid management in this setting may focus on lipid testing as an indicator of lipid management. We describe the detection, treatment, and control of dyslipdemia for African Americans and Caucasians with coronary artery disease to evaluate whether public health programs focusing on lipid testing can eliminate racial disparities in lipid management. Methods Physicians and medical practices with high numbers of prescriptions for coronary artery disease medications were invited to participate in the Quality Assurance Program. Medical records were reviewed from a random sample of patients with coronary artery disease seen from 1995 through 1998. Data related to the detection, treatment, and control of dyslipidemia were abstracted from the medical record and evaluated in cross-sectional stratified and logistic regression analyses using generalized estimation equations. Results Data from the medical records of 1,046 African Americans and 22,077 Caucasians seen in outpatient medical practices in 23 states were analyzed. African-American patients were younger, more likely to be women and to have diabetes, heart failure, and hypertension. The low density lipoprotein cholesterol (LDL-C testing rate for Caucasian men was over 1.4 times higher than that for African-American women and about 1.3 times higher than that for African-American men. Almost 60% of tested Caucasian men and less than half of tested African Americans were prescribed lipid-lowering drugs. Tested and treated Caucasian men

Female feticide--the selective abortion of female fetuses--is killing upwards of one million females in India annually with far-ranging and tragic consequences. In some areas, the sex ratio of females to males has dropped to less than 8000:1000. Females not only face inequality in this culture, they are even denied the right to be born. Why do so many families selectively abort baby daughters? In a word: economics. Aborting female fetuses is both practical and socially acceptable in India. Female feticide is driven by many factors, but primarily by the prospect of having to pay a dowry to the future bridegroom of a daughter. While sons offer security to their families in old age and can perform the rites for the souls of deceased parents and ancestors, daughters are perceived as a social and economic burden. Prenatal sex detection technologies have been misused, allowing the selective abortions of female offspring to proliferate. Legally, however, female feticide is a penal offence. Although female infanticide has long been committed in India, feticide is a relatively new practice, emerging concurrently with the advent of technological advancements in prenatal sex determination on a large scale in the 1990s. While abortion is legal in India, it is a crime to abort a pregnancy solely because the fetus is female. Strict laws and penalties are in place for violators. These laws, however, have not stemmed the tide of this abhorrent practice. This article will discuss the socio-legal conundrum female feticide presents, as well as the consequences of having too few women in Indian society.

    Several studies have reported differences between African Americans and Caucasians in relative proportion of psychotic symptoms and disorders, but whether this reflects racial bias in the assessment of psychosis is unclear. The purpose of this study was to examine the distribution of psychotic symptoms and potential bias in symptoms assessed via semi-structured interview using a cohort of 3,389 African American and 5,692 Caucasian participants who were diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder. In this cohort, the diagnosis of schizophrenia was relatively more common, and the diagnosis of bipolar disorder and schizoaffective disorder-bipolar type was less relatively common, among African Americans than Caucasians. With regard to symptoms, relatively more African Americans than Caucasians endorsed hallucinations and delusions symptoms, and this pattern was striking among cases diagnosed with bipolar disorder and schizoaffective-bipolar disorder. In contrast, the relative endorsement of psychotic symptoms was more similar among cases diagnosed with schizophrenia and schizoaffective disorder-depressed type. Differential item function analysis revealed that African Americans with mild psychosis over-endorsed "hallucinations in any modality" and under-endorsed "widespread delusions" relative to Caucasians. Other symptoms did not show evidence of racial bias. Thus, racial bias in assessment of psychotic symptoms does not appear to explain differences in the proportion of symptoms between Caucasians and African Americans. Rather, this may reflect ascertainment bias, perhaps indicative of a disparity in access to services, or differential exposure to risk factors for psychosis by race. © 2015 Wiley Periodicals, Inc.

    Objective to assess Female Sexual Function Index (FSFI) scores and delay to resume sexual activity associated with a previous severe maternal morbidity. Method This was a multidimensional retrospective cohort study. Women who gave birth at a Brazilian tertiary maternity between 2008 and 2012 were included, with data extraction from the hospital information system. Those with potentially life-threatening conditions and maternal near miss episodes (severe maternal morbidity) were considered the exposed group. The control group was a random sample of women who had had uncomplicated pregnancy. Female sexual function was evaluated through FSFI questionnaire, and general and reproductive aspects were addressed through specific questions. Statistical analyses were performed using Mann-Whitney and Pearson´s Chi-square for bivariate analyses. Logistic regression was used to identify variables independently associated with lower FSFI scores. Results 638 women were included (315 at exposed and 323 at not exposed groups). The majority of women were under 30 years-old in the control group and between 30 and 46 years-old in the exposed group (p = 0.003). Women who experienced severe maternal morbidity (SMM) had statistically significant differences regarding cesarean section (82.4% versus 47.1% among deliveries without complications, p<0.001), and some previous pathological conditions. FSFI mean scores were similar among groups ranging from 24.39 to 24.42. It took longer for exposed women to resume sexual activity after index pregnancy (mean 84 days after SMM and 65 days for control group, p = 0.01). Multiple analyses showed no significant association of FSFI below cut-off value with any predictor. Conclusion FSFI scores were not different in both groups. However, they were lower than expected. SMM delayed resumption of sexual activity after delivery, beyond postpartum period. However, the proportion of women in both groups having sex at 3 months after delivery was similar

    Major depressive disorder (MDD) is a complex neuropsychiatric disorder where both gene-gene and gene-environment interactions play an important role, but the clues are still not fully understood. One carbon metabolism in the CNS plays a critical role in the synthesis and release of neurotransmitters which are relevant to depressive disorder. We studied genetic polymorphisms of the brain derived neurotrophic factor (BDNF) and the methylenetetrahydrofolate reductase (MTHFR) in association with major depressive disorder. We genotyped the BDNF G196A, the MTHFR C677T, and A1298C polymorphisms in 134 patients diagnosed with major depression and 143 control subjects in Slovak (Caucasian) cohort of patients and probands. We found no significant association of either the BDNF G196A or MTHFR C677T polymorphisms with major depressive disorder neither in female nor male group of patients. However, the MTHFR A1298C genotype distribution was 36.6% (for AA genotype), 48.5% (AC) and 14.9% (CC) for the depressed patients, and 48.9% (AA), 42.7% (AC) and 8.4% (CC), respectively, for the control subjects. Patients with MDD had a higher prevalence of the CC genotype (OR = 2.38; 95% CI = 1.07-5.32; p = 0.032) and the AC + CC genotype (OR = 1.67; 95% CI = 1.03-2.69; p = 0.037) in comparison with the control subjects. This study shows that CC genotype of the MTHFR A1298C is associated with higher risk of MDD in Slovak population.

    Full Text Available Spontaneous preterm birth (<37 weeks gestation-PTB occurs in approximately 12% of pregnancies in the United States, and is the largest contributor to neonatal morbidity and mortality. PTB is a complex disease, potentially induced by several etiologic factors from multiple pathophysiologic pathways. To dissect the genetic risk factors of PTB a large-scale high-throughput candidate gene association study was performed examining 1536 SNP in 130 candidate genes from hypothesized PTB pathways. Maternal and fetal DNA from 370 US Caucasian birth-events (172 cases and 198 controls was examined. Single locus, haplotype, and multi-locus association analyses were performed separately on maternal and fetal data. For maternal data the strongest associations were found in genes in the complement-coagulation pathway related to decidual hemorrhage in PTB. In this pathway 3 of 6 genes examined had SNPs significantly associated with PTB. These include factor V (FV that was previously associated with PTB, factor VII (FVII, and tissue plasminogen activator (tPA. The single strongest effect was observed in tPA marker rs879293 with a significant allelic (p = 2.30x10(-3 and genotypic association (p = 2.0x10(-6 with PTB. The odds ratio (OR for this SNP was 2.80 [CI 1.77-4.44] for a recessive model. Given that 6 of 8 markers in tPA were statistically significant, sliding window haplotype analyses were performed and revealed an associating 4 marker haplotype in tPA (p = 6.00x10(-3. The single strongest effect in fetal DNA was observed in the inflammatory pathway at rs17121510 in the interleukin-10 receptor antagonist (IL-10RA gene for allele (p = 0.01 and genotype (p = 3.34x10(-4. The OR for the IL-10RA genotypic additive model was 1.92 [CI 1.15-3.19] (p = 2.00x10(-3. Finally, exploratory multi-locus analyses in the complement and coagulation pathway were performed and revealed a potentially significant interaction between a marker in FV (rs2187952 and FVII (rs3211719 (p

    Full Text Available BACKGROUND: Characterization of abdominal and intra-abdominal fat requires imaging, and thus is not feasible in large epidemiologic studies. OBJECTIVE: We investigated whether biomarkers may complement anthropometry (body mass index [BMI], waist circumference [WC], and waist-hip ratio [WHR] in predicting the size of the body fat compartments by analyzing blood biomarkers, including adipocytokines, insulin resistance markers, sex steroid hormones, lipids, liver enzymes and gastro-neuropeptides. METHODS: Fasting levels of 58 blood markers were analyzed in 60 healthy, Caucasian or Japanese American postmenopausal women who underwent anthropometric measurements, dual energy X-ray absorptiometry (DXA, and abdominal magnetic resonance imaging. Total, abdominal, visceral and hepatic adiposity were predicted based on anthropometry and the biomarkers using Random Forest models. RESULTS: Total body fat was well predicted by anthropometry alone (R(2 = 0.85, by the 5 best predictors from the biomarker model alone (leptin, leptin-adiponectin ratio [LAR], free estradiol, plasminogen activator inhibitor-1 [PAI1], alanine transaminase [ALT]; R(2 = 0.69, or by combining these 5 biomarkers with anthropometry (R(2 = 0.91. Abdominal adiposity (DXA trunk-to-periphery fat ratio was better predicted by combining the two types of predictors (R(2 = 0.58 than by anthropometry alone (R(2 = 0.53 or the 5 best biomarkers alone (25(OH-vitamin D(3, insulin-like growth factor binding protein-1 [IGFBP1], uric acid, soluble leptin receptor [sLEPR], Coenzyme Q10; R(2 = 0.35. Similarly, visceral fat was slightly better predicted by combining the predictors (R(2 = 0.68 than by anthropometry alone (R(2 = 0.65 or the 5 best biomarker predictors alone (leptin, C-reactive protein [CRP], LAR, lycopene, vitamin D(3; R(2 = 0.58. Percent liver fat was predicted better by the 5 best biomarker predictors (insulin, sex hormone binding globulin [SHBG], LAR, alpha-tocopherol, PAI1; R(2 = 0

    Objective To investigate the possible association of the BANK1 gene with genetic susceptibility to systemic sclerosis (SSc) and its subphenotypes. Methods A large multicentre case–control association study including 2380 patients with SSc and 3270 healthy controls from six independent case–control sets of Caucasian ancestry (American, Spanish, Dutch, German, Swedish and Italian) was conducted. Three putative functional BANK1 polymorphisms (rs17266594 T/C, rs10516487 G/A, rs3733197 G/A) were selected as genetic markers and genotyped by Taqman 5´ allelic discrimination assay. Results A significant association of the rs10516487 G and rs17266594 T alleles with SSc susceptibility was observed (pooled OR=1.12, 95% CI 1.03 to 1.22; p=0.01 and pooled OR=1.14, 95% CI 1.05 to 1.25; p=0.003, respectively), whereas the rs3733197 genetic variant showed no statistically significant deviation. Stratification for cutaneous SSc phenotype showed that the BANK1 rs10516487 G, rs17266594 T and rs3733197 G alleles were strongly associated with susceptibility to diffuse SSc (dcSSc) (pooled OR=1.20, 95% CI 1.05 to 1.37, p=0.005; pooled OR=1.23, 95% CI 1.08 to 1.41, p=0.001; pooled OR=1.15, 95% CI 1.02 to 1.31, p=0.02, respectively). Similarly, stratification for specific SSc autoantibodies showed that the association of BANK1 rs10516487, rs17266594 and rs3733197 polymorphisms was restricted to the subgroup of patients carrying anti-topoisomerase I antibodies (pooled OR=1.20, 95% CI 1.02 to 1.41, p=0.03; pooled OR=1.24, 95% CI 1.05 to 1.46, p=0.01; pooled OR=1.26, 95% CI 1.07 to 1.47, p=0.004, respectively). Conclusion The results suggest that the BANK1 gene confers susceptibility to SSc in general, and specifically to the dcSSc and anti-topoisomerase I antibody subsets. PMID:19815934

    Full Text Available More than 70 % of the Caucasian Black Sea Coast (CBSC forests grow in mountainous conditions of the Colchis phytogeographical province and perform primary environmental functions. In these forests for a long period of time excessively intense logging has been in practice, which caused serious damage to their health. The main issues of forestry here are the introduction of effective methods of harvesting, using rational technology in logging operations, restoring native forest types at past logging sites, increasing the productivity and sustainability of forests on the bioecological biogeocenotical level, and preserving the riparian-protective role of forests. In the article, the author analyzes the results of many years of research in forests of the CBSC, that consider the question of condition of forests, peculiarity the multifunctional values and priority direction forestry in them. The author also considers the basic conformity of structure and com-position of forest stands, and presents evidence about the natural renewal of logging sites in fir and beech forests. It has been established that high intensity selective logging more than 50 % canopy cover and bringing the stand after logging 0.5 and below leads to degradation of forests, except for the possibility of natural regeneration felling areas for over 70 years. The study substantiates the effectiveness of selective forms of forest management in the uneven-aged stands and the importance of a multi-purpose and sustainable use of forest resources. The study emphasizes the need for a rational technology of logging operations and silvicultural demands strict compliance with the development of cutting areas and suggests ways to improve the productivity of forests, using introduced valuable tree species. For example, Sequoia sempervirens Endl. in the plantings of forest monocultures on the Abkhazian Research Forest Experimental Station (Ochamchira at age of 50 years forms a valuable timber of

    This cross-sectional study aimed to determine ethnic and environmental influences on the relationship between BMI and percentage body fat, using a sample of 144 Japanese and 140 Australian-Caucasian men living in Australia, and eighty-eight Japanese men living in Japan. Body composition was assessed by anthropometry using standard international methods (International Society for the Advancement of Kinanthropometry protocol). Body density was predicted using Durnin and Womersley's (1974) equation, and percentage body fat was calculated from Siri's (1961) equation. Significant (P<0.05) ethnic differences in stature, body mass and BMI were observed between Japanese and Australian men, but no ethnic differences were observed in their percentage body fat and height-corrected sum of skinfold thicknesses. No differences were found in the BMI-percentage body fat relationship between the Japanese subjects living in Australia and in Japan. Significant (P<0.05) ethnic differences in the BMI-percentage body fat relationship observed from a comparison between pooled Japanese men (aged 18-40 years, BMI range 16.6-32.8 kg/m2) and Australians (aged 18-39 years, BMI range 16.1-31.4 kg/m2) suggest that Japanese men are likely to have a greater percentage body fat than Australian men at any given BMI value. From the analyses, the Japanese men were estimated to have an equivalent amount of body fat to the Australian men at BMI values that were about 1.5 units lower than those of the Australians (23.5 kg/m2 and 28.2 kg/m2, respectively). It was concluded that Japanese men have greater body fat deposition than Australian-Caucasians at the same BMI value. Japanese men may therefore require lower BMI cut-off points to identify obese individuals compared with Australian-Caucasian men.

    Full Text Available The domestic Caucasus Studies contains various, often conflicting concepts and approaches, claiming to be the most complete and objective coverage of issues of Russian-Caucasian historical interaction. Though in different studies, the same category is filled with a variety of semantic content that creates a discursive field requiring thorough scientific research. The article analyzes the research works of official direction of pre-revolutionary historiography devoted to the problem of relations between Russia and the North Caucasus in the XVI–XIX centuries. The disciplinary matrix of historical science of J. Ryuzen is used as an instrument of historiographical analysis in this research. This theoretical construct allowed to typologize and to conceptualize the pre-revolutionary studies, to formulate criteria for selection of the conservative direction in the study of the Russian-Caucasian relations. The authors of the article relate the works of M.M. Shcherbatov, N.K. Karamzin, P.P. Zubov, R.А. Fadeev, A.P. Berge, N.F. Dubrovin, V.A. Potto, D.N. Dubenskiy, I. Ivanin, S.S. Esadze et al to the research works of the official direction of the pre-revolutionary historical thought. The cognitive interest of this group of researchers is caused by the search for the most effective ways of conquest and managing the North Caucasian peoples. Caucasus war was examined by the researchers-conservatives as the process of strengthening the position of the Russian Empire in the North Caucasus region justified from a historical and geopolitical point of view. The official approach supposed the civilizational motivation for the particular military conquest of the North Caucasus societies, deprived of citizenship and social order. The authors conclude that the research works of the conservative direction of imperial historiography solve important problems of legitimation of the Russian policy in the North Caucasus.

    Full Text Available Abstract Background Previous population-based studies showed differences in international and within country colorectal cancer survival estimates, but few investigated the role of prognostic factors. Using a "high resolution approach", we aimed to determine the effect of ethnicity and health care by comparing Filipino-Americans with Philippine residents, who have the same ethnicity, and with Caucasians living in the US, who have the same health care system. Methods Using databases from the Manila and Rizal Cancer Registries and the United States Surveillance, Epidemiology and End Results, age-adjusted five-year absolute and relative survival estimates were computed and compared between Filipino-American colorectal cancer patients, cancer patients from the Philippines and Caucasian patients. Cox proportional hazards modelling was used to determine factors affecting survival differences. Results Much lower 5-year relative survival estimates were obtained for Philippine residents (37% as compared to those in Filipino-Americans (60.3% and Caucasians (62.4%. Differences in age, stage and receipt of surgery explained a large proportion of the survival differences between Philippine residents and Filipino-Americans. However, strong excess risk of death for Philippine residents remained after controlling for these and other variables (relative risk, RR, 2.03, 95% confidence interval, 95% CI, 1.83-2.25. Conclusions Strong survival disadvantages of Philippine residents compared to Filipino-American patients were disclosed, which most likely reflect differences in access to and utilization of health care. Health education and advocacy, for both patients and health practitioners, should likewise be given priority.

    This study investigated the prevalence of the signs and symptoms of temporomandibular disorders (TMD) in a population of children and adolescents. TMD signs and symptoms were recorded in 1134 subjects (593 males and 541 females; age range 5-15 years), divided into various groups according to the: (i) Angle dental class; (ii) presence and type of crossbite; (iii) gender; and (iv) age (ages 5-11 and 12-15 years). The percentages of signs and symptoms were compared using the chi2-test to determine the differences among the groups for the rates of TMD symptoms, bruxism, joint sounds, deviation during opening, reduced opening/lateral/protrusive movements, and myofascial pain. Subjects who were 12-15 years old showed a significantly higher prevalence of myofascial pain than those who were 5-11 years old (chi2 = 4.263; p < 0.05). Females showed a significantly higher prevalence of myofascial pain than males (chi2 = 3.882; p < 0.05). Subjects with posterior, unilateral crossbite showed a significantly higher prevalence of TMD symptoms (chi2 = 33.877; p < 0.001) and reduction of functional movements (chi2 = 10.800; p < 0.05) than those with no crossbite, or with anterior or posterior bilateral crossbite. TMD's signs and symptoms seem to be associated to some definite characteristics of the patient, such as female gender, young age, and presence of posterior unilateral crossbite.

    2016-01-01

    Female genital mutilation (FGM), otherwise known as female genital cutting (FGC), is currently very topical and has become a significant global political issue. The impact of FGM on the lives of women and girls is enormous, as it often affects both their psychology and physical being. Among the complications that are often under-reported and not always acknowledged is female sexual dysfunction (FSD). FSD presents with a complex of symptoms including lack of libido, arousability and orgasm. This often occurs in tandem with chronic urogenital pain and anatomical disruption due to perineal scarring.To treat FSD in FGM each woman needs specifically directed holistic care, geared to her individual case. This may include psychological support, physiotherapy and, on occasion, reconstructive surgery. In many cases the situation is complicated by symptoms of chronic pelvic pain, which can make treatment increasingly difficult as this issue needs a defined multidisciplinary approach for its effective management in its own right. The problems suffered by women with FGM are wholly preventable, as the practice need not happen. The current global momentum to address the social, cultural, economic and medical issues of FGM is being supported by communities, governments, non-governmental agencies (NGOs) and healthcare providers. It is only by working together that the practice can be abolished and women and girls may be free from this practice and its associated consequences.

During a lifetime, skin will change in appearance and structure not only because of chronological and intrinsic processes but also due to several external factors such as gravity, sun and ultraviolet exposure, and high levels of pollution; or lifestyle factors that have important and obvious effects on skin aging, such as diet, tobacco, illness, or stress. The effect of these external factors leads to progressive degradations of tegument that appear with different kinetics. The aim of this study was to clinically quantify the effect of sun exposure on facial aging in terms of the appearance of new specific signs or in terms of increasing the classical signs of aging. Materials and methods: This study was carried out on 298 Caucasian women from 30 years to 78 years old. The participants were divided into two groups according to their sun exposure history: 157 women were characterized as sun-seeking, and the other 141 were classified as sun-phobic. This division was made possible by dermatologist grading of heliodermal status on the basis of several observations of classic criteria: wrinkles, sagging, pigmentation heterogeneities, vascular disorders, elastosis, and so on. This work was an opportunity to complete clinical photographic tools by adding in our portfolio new scales for signs observed in the two groups. Thus, 22 clinical parameters were investigated by a panel of twelve trained experts to characterize each woman

    Full Text Available Cutis Marmorata Telangiectatica Congenita (CMTC is a rare, sporadic condition usually present at birth characterized by localized or generalized persistent cutis marmorata, telangiectasia and phlebectasia. We report a preterm female newborn, the third child of non-related caucasian parents, with CMTC at birth who showed typical cutaneous features and monolateral congenital glaucoma. The pathogenesis of this disorder is unknown and the cause is probably multifactorial. Teratogens and autosomal dominant mode of inheritance with incomplete penetrance have been considered as etiological factors. Prognosis, in uncomplicated cases, is good.

    Full Text Available Takayasu’s arteritis (TA and Crohn’s disease (CD are chronic inflammatory granulomatous disorders of undetermined etiology. TA is a large vessel vasculitis with a predilection for the aorta and its branches in young women of Asian descent; whereas CD has characteristic gastrointestinal manifestations more prevalent in young Caucasians. We describe a case of both diseases in a young Hispanic female, review the literature, and impart new insight on possible genetic linkage and the role of interleukin 12 B (IL-12B as the common autoimmune mechanism and potential therapeutic target in this rare disease combination.

    2013-01-01

    The concept of the ideal female eyebrow has changed over time. Modern studies examining youthful brow aesthetics are reviewed. An analysis of ideal female brow characteristics as depicted in the Western print media between 1945 and 2011 was performed. This analysis provided objective evidence that the ideal youthful brow peak has migrated laterally over time to lie at the lateral canthus. There has been a nonstatistically significant trend toward lower and flatter brows. These findings are discussed in relation to current concepts of female brow aging, with repercussions regarding endoscopic brow lift and aesthetic forehead surgery.

    Full Text Available Catalase is a central antioxidant enzyme constituting the primary defense against oxidative stress. In this study, we investigated whether the functional –262C/T polymorphism in the promoter of catalase gene is associated with the presence of diabetic retinopathy (DR, diabetic nephropathy (DN and ischemic heart disease (IHD in 520 Caucasian-Brazilians with type 2 diabetes. The –262C/T polymorphism was also examined in 100 Caucasian blood donors. Patients underwent a clinical and laboratory evaluation consisting of a questionnaire, physical examination, assessment of diabetic complications and laboratory tests. Genotype analysis was performed using the polymerase chain reaction followed by digestion with restriction enzyme. The genotype and allele frequencies of the –262C/T polymorphism in patients with type 2 diabetes were very similar to those of blood donors (T allele frequency = 0.20 and 0.18, respectively. Likewise, there were no differences in either genotype or allele frequencies between type 2 diabetic patients with or without DR, DN or IHD. Thus, our results do not support the hypothesis that the –262C/T polymorphism is related to the development of DR, DN or IHD in patients with type 2 diabetes. Further studies are necessary to elucidate the role of catalase gene polymorphisms in the pathogenesis of diabetic complications.

    The aetiology of childhood asthma is complex. An early dysfunction in the immunological development of the innate immune system in combination with environmental factors possibly triggers asthma. CD14 and toll-like receptors are important components of the innate immune system. The aim of this systematic review was to obtain a better insight into the relation between CD14 and toll-like receptors and childhood asthma in Caucasians. We searched PubMed and EMBASE for relevant articles. In total, 44 articles were included. The quality of the selected studies was independently assessed by the first two authors using the Newcastle-Ottawa quality assessment scale. Toll-like receptor 2, toll-like receptor 6, toll-like receptor 9, and toll-like receptor 10 appear to have some association with childhood asthma in Caucasians. The evidence for a relation of CD14 with childhood asthma is limited. In conclusion, there is no convincing evidence yet for a role of CD14 and toll-like receptors in relation to childhood asthma. Future studies should include haplotype analysis and take environmental factors into account to further clarify the role of CD14 and toll-like receptors on childhood asthma.

    The authors examined the association between self-reported experiences of discrimination and subtypes of abdominal fat (visceral, subcutaneous) in a population-based cohort of African-American and Caucasian women. Prior studies examining associations between discrimination and abdominal fat have yielded mixed results. A major limitation of this research has been the reliance on waist circumference, which may be a poor marker of visceral fat, particularly for African-American women. Participants were 402 (45% African-American, 55% Caucasian) middle-aged women from the Chicago, Illinois, site of the Study of Women's Health Across the Nation. Visceral and subcutaneous fat were assessed via computed tomography scans between 2002 and 2005. Linear regression models were conducted to test associations among discrimination and visceral and subcutaneous fat. After adjustment for age and race, every one-point increase on the discrimination scale was associated with a 13.03-cm(2) higher amount of visceral fat (P = 0.04). This association remained significant after further adjustments for total body fat and relevant risk factors, including depressive symptoms. Discrimination was not associated with subcutaneous fat in minimally (P = 0.95) or fully adjusted models. Associations did not differ by race. Findings suggest that visceral fat may be one potential pathway through which experiences of discrimination increase cardiovascular risk.

    This study was performed to evaluate the pharmacokinetics (PK), pharmacodynamics (PD) and safety of GSK1278863, a novel prolyl hydroxylase inhibitor, following a single oral administration of GSK1278863 from 10 to 100 mg or placebo in Japanese (n = 19), and 10, 25 and 100 mg in Caucasians (n = 14). Dose-proportional increases were observed in AUCinf of GSK1278863 in both ethnic groups, with a 1.3-1.5-fold higher exposure seen in Japanese relative to Caucasians for all doses. This difference in exposure can be mainly explained by the observed differences in body weights between the two groups. Statistically significant increases in erythropoietin (EPO), vascular endothelial growth factor (VEGF) and reticulocyte counts were observed in Japanese subjects after the 50 and 100 mg dose as compared to placebo. In Caucasians, similar to Japanese, EPO and VEGF levels were observed to be increased in response to the 100 mg dose. Drug-related adverse events, including headache and abdominal pain were reported in 3 Japanese subjects, while headache was reported in 3 Caucasians. In conclusion, GSK1278863 was well tolerated, with dose-proportional increases in exposure observed in both groups. There was no evidence of ethnic differences between Japanese and Caucasian with regard to PK or PD.

    The Combination of Avodart and Tamsulosin study was a 4-year, randomized, double-blind study of the efficacy and safety of dutasteride and tamsulosin, alone or in combination, in men with moderate-to-severe benign prostatic hyperplasia. In this post-hoc investigation, we analyzed primary and secondary end-points from the Combination of Avodart and Tamsulosin study in Asian (n = 325) and Caucasian men (n = 4259). The incidence of acute urinary retention or benign prostatic hyperplasia-related surgery did not differ significantly between treatment groups in the Asian subpopulation. In Caucasian men, the incidence of acute urinary retention/benign prostatic hyperplasia-related surgery was significantly lower in the combination therapy group compared with the tamsulosin monotherapy group (P benign prostatic hyperplasia clinical progression and resulted in improved International Prostate Symptom Score, maximum urinary flow rate, quality of life, and reduced prostate volume in Asian and Caucasian men who received combination therapy compared with tamsulosin monotherapy. Combination therapy also significantly improved (P benign prostatic hyperplasia clinical progression, International Prostate Symptom Score, maximum urinary flow rate and quality of life versus dutasteride in the Caucasian subpopulation. The adverse-event profile was comparable between subpopulations. In conclusion, Asian and Caucasian men respond similarly to these treatments, despite apparent racial differences in 5α-reductase activity.

    Full Text Available Two microsatellites from corticotropin releasing hormone (CRH gene locus (CRHRA1 and CRHRA2 were reported to be associated with rheumatoid arthritis (RA in Caucasians. This study aims to replicate the association in a South Asian (SA and Caucasian RA sample from the East Midlands, UK. DNA from 281 South Asians (111 patients, 43 siblings, 127 controls and 287 Caucasians (116 patients, 64 siblings, 107 controls were genotyped. The Odds Ratio for carrying at least one copy of the CRHRA1*10 risk allele was 1.32 (Confidence Interval, CI=0.77-2.28 in Caucasians and 1.55 (CI=0.92-2.63 in South Asians, indicative of a trend for association. The risk allele CRHRA2*14 was lower in South Asians compared to Caucasians (5.5%-8.6% vs. 17.7-18.2 %; P<0.005. Significant linkage disequilibrium was observed between CRHRA1 and CRHRA2 in both cohorts. CRHRA1*10 was the frequently transmitted allele in SA patients. A non-significant association was observed with CRHRA1*10 allele in both RA populations.

    Preservation of female fertility is an important issue today. However, there are few effective clinical options for preserving female fertility. Firstly, conventional in vitro fertilization (IVF) followed by embryo cryopreservation is an accepted procedure but is not applicable to all women. Embryo freezing is suitable only for women with a male partner and may not be acceptable to some patients due to moral and religious reasons. Ovarian tissue freezing is another option of female fertility preservation but is an invasive procedure and the efficacy of this technique remains to be determined.Oocyte cryopreservation is also method for fertility preservation. Egg freezing is minimally invasive and can avoid the ethical and moral concerns related to cryopreservation of embryos. However, conventional slow freezing/rapid thawing methods are associated with low survival of oocytes. Recent development in vitrification of oocytes appears promising. Therefore, vitrification of unfertilized eggs may be a novel method to preserve female fertility.

    Male harassment of females to gain mating opportunities is a consequence of an evolutionary conflict of interest between the sexes over reproduction and is common among sexually reproducing species. Male Trinidadian guppies Poecilia reticulata spend a large proportion of their time harassing females for copulations and their presence in female social groups has been shown to disrupt female-female social networks and the propensity for females to develop social recognition based on familiarity. In this study, we investigate the behavioural mechanisms that may lead to this disruption of female sociality. Using two experiments, we test the hypothesis that male presence will directly affect social behaviours expressed by females towards other females in the population. In experiment one, we tested for an effect of male presence on female shoaling behaviour and found that, in the presence of a free-swimming male guppy, females spent shorter amounts of time with other females than when in the presence of a free-swimming female guppy. In experiment two, we tested for an effect of male presence on the incidence of aggressive behaviour among female guppies. When males were present in a shoal, females exhibited increased levels of overall aggression towards other females compared with female only shoals. Our work provides direct evidence that the presence of sexually harassing males alters female-female social behaviour, an effect that we expect will be recurrent across taxonomic groups.

    Chronic low-grade activation of the immune system may play a role in the pathogenesis of type-2 diabetes mellitus (T2DM). Interleukin-6 (IL6), a powerful inducer of hepatic acute phase response, has been implicated in the etiology of insulin resistance and T2DM. Recently, an IL6 promoter...... polymorphism (G/C) at position -174 was found to be associated with measures of insulin sensitivity. Because we have previously found an association between high IL6 levels and insulin resistance in both Pima Indians - a population with high rates of insulin resistance and T2DM - and Caucasians, we aimed...... to assess whether the IL6 promoter polymorphism is associated with T2DM in these populations. We genotyped the IL6 (-174) G/C polymorphism using pyrosequencing in 463 Native Americans and by PCR-RFLP in 329 Spanish Caucasians. Among the Spanish Caucasian subjects, there was a significant difference...

    Recent studies have shown that participants use different eye movement strategies when scanning own- and other-race faces. However, it is unclear (1) whether this effect is related to face recognition performance, and (2) to what extent this effect is influenced by top-down or bottom-up facial information. In the present study, Chinese participants performed a face recognition task with Chinese, Caucasian, and racially ambiguous faces. For the racially ambiguous faces, we led participants to believe that they were viewing either own-race Chinese faces or other-race Caucasian faces. Results showed that (1) Chinese participants scanned the nose of the true Chinese faces more than that of the true Caucasian faces, whereas they scanned the eyes of the Caucasian faces more than those of the Chinese faces; (2) they scanned the eyes, nose, and mouth equally for the ambiguous faces in the Chinese condition compared with those in the Caucasian condition; (3) when recognizing the true Chinese target faces, but not the true target Caucasian faces, the greater the fixation proportion on the nose, the faster the participants correctly recognized these faces. The same was true when racially ambiguous face stimuli were thought to be Chinese faces. These results provide the first evidence to show that (1) visual scanning patterns of faces are related to own-race face recognition response time, and (2) it is bottom-up facial physiognomic information that mainly contributes to face scanning. However, top-down knowledge of racial categories can influence the relationship between face scanning patterns and recognition response time.

    2013-01-01

    Background Melasma is a common hypermelanosis of the face. The use of a classical Q-switched ruby laser (QSRL) to treat melasma is discussed controversially and is associated with frequent adverse effects, such as hyper- or hypopigmentation. Recently a fractional-mode (FRx) QSRL was developed to minimize the adverse effects of classical QSRL. The objective of this research was to evaluate the efficacy and safety of a novel FRx-QSRL in the treatment of melasma in Caucasian patients. Methods We performed a retrospective study of 25 Caucasian melasma patients (Fitzpatrick skin types I to III). Patients received one to three FRx-QSRL treatments (Tattoostar FRx, Asclepion Laser Technologies, Jena, Germany) at pulse energies of 4 to 8 J/cm2. Three blinded investigators independently evaluated the melasma area and severity index (MASI) score before treatment and at the four- to six-week follow-ups. At additional three-month follow-ups, patients evaluated subjective improvement, pain and over-all satisfaction with the treatment according to a numeric analogue score (NAS). Side effects were documented. Results At four to six weeks post laser treatment for a mean of 1.4 sessions, we observed a significant (P = 0.0001) reduction of the MASI score from 6.54 to 1.98 (72.3%). Patients rated the pain of the intervention at a mean 2.46 points (0 = no pain; 10 = maximum pain), the improvement at a mean 5.55 points (0 = no improvement; 10 = maximum improvement) and the overall satisfaction at a mean 4.66 points (0 = not satisfied; 10 = maximum satisfaction). After three months, post-inflammatory hyperpigmentation (PIH) and/or recurring melasma were observed in 7 (28%) and 11 (44%) patients, respectively. Conclusion The 694-nm FRx-QSRL is a safe and effective option for treating melasma in Caucasian patients. Over periods of >3 months, PIH and/or recurring melasma may develop at significant rates and may reduce patient satisfaction. Multiple treatment

    Aim: To simultaneously investigate the contribution of the alpha 1 chain of col-lagen type 1 (COL1A1) and alpha2-HS-glycoprotein (AHSG) genes to the varia-tion of bone geometric parameters in both Caucasians and Chinese. Methods: Six hundred and five Caucasian individuals from 157 nuclear families and 1228 Chi-nese subjects from 400 nuclear families were genotyped at the AHSG-Sacl, COL1A1-PCOL2 and Sp1 polymorphisms using polymerase chain reaction (PCR)-restric-tion fragment length polymorphism (RFLP). 5 FN bone geometric parameters were calculated based on bone mineral density and bone area of femoral neck (FN)measured by dual energy X-ray absorptiometry. Population stratification, total family association, within-family association, and linkage tests were performed by the quantitative transmission disequilibrium test program. Results: The t-test showed the significant differences of all bone geometric phenotypes (except ED)between Caucasians and Chinese in the offspring using both unadjusted and adjusted (by age, height, weight, and gender) data. In Caucasians, we found significant within-family association results between the COL1A1-Sp1 polymor-phism (rs1800012) and cross sectional area (CSA), cortical thickness (CT),endocortical diameter (ED), buckling ratio (BR) (P=0.018, 0.002, 0.023, and 0.001,respectively); the COL1A1-Sp1 polymorphism also detected significant linkage with BR (P=0.039). In the population of China, the within-family associations between the COL1A1-PCOL2 polymorphism (rs1107946) and CT, BR were signifi-cant (P=0.012 and 0.008, respectively). Furthermore, evidence of linkage were observed between the AHSG-SacI polymorphism (rs4918) and CT, BR (P--0.042 and 0.014, respectively) in Caucasians, but not in Chinese. Conclusion: Our results suggest that the COL1A1 gene may have significantly association with bone geometry in both Caucasians and Chinese, and the AHSG gene may be linked to bone geometry in Caucasians, but not in Chinese.

    1993-08-21

    Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees.

    The passage of Title IX legislation in 1972 provided enormous opportunities for women to reap the benefits of sports participation. For most female athletes, sports participation is a positive experience, providing improved physical fitness, enhanced self-esteem, and better physical and mental health. Nonetheless, for a few female athletes, the desire for athletic success combined with the pressure to achieve a prescribed body weight may lead to the development of a triad of medical disorders including disordered eating, menstrual dysfunction, and low bone mineral density (BMD)--known collectively as the female athlete triad. Alone or in combination, the disorders of the triad can have a negative impact on health and impair athletic performance.

    Predictive potential distribution modeling is crucial in outlining habitat usage and establishing conservation management priorities. In this paper we provide detailed data on the distribution of the Caucasian rock agama Para-laudakia caucasia, and use species distribution models (MAXENT) to evaluate environmental suitability and potential distribution at a broad spatial scale. Locality data on the distribution of P. caucasia have been gathered over nearly its entire range by various authors from ifeld surveys. The distribution model of P. caucasia showed good performance (AUC=0.887), and predicted high suitability in regions mainly located in Tajikistan, north Pakistan, Afghanistan, southeast Turkmenistan, northeast Iran along the Elburz mountains, Transcaucasus (Azerbajan, Armenia, Georgia), northeastern Turkey and northward along the Caspian Sea coast in Daghestan, Russia. The identiifcation of suitable areas for this species will help to assess conservation status of the species, and to set up management programs.

This article presents an empirical study on the lexical knowledge of Caucasian Urum speakers, i. e., ethnic Greek speakers in the Small Caucasus, who are bilingual in a variety of Turkish (Urum and Russian. The analysis is based on the established assumption that certain concepts are cross-linguistically associated with a certain likelihood of borrowing. Based on this assumption the data from lexical knowledge allow for insights with respect to the substrate/superstrate status of the involved languages in a multilingual situation and provide evidence for the type of relation (genetic or contact-induced between compared languages.

    Blood samples from 409-452 unrelated Colombian Caucasian-Mestizo individuals were amplified and typed for six short tandem repeat (STR) markers (HUMF13A01, HUMFES/FPS, HUMVWA, HUMCSF1PO, HUMTPOX, HUMTH01). The allele frequencies, genotype frequencies, heterozygosity, mean paternity exclusion chance, polymorphism information content, discrimination power, assumption of independence within and between loci and Hardy Weinberg equilibrium were determined. The results demonstrate that all markers conform to Hardy-Weinberg equilibrium expectations. In addition, the results demonstrate the assumption of independence within and between the loci analysed. The mean exclusion chance (MEC) was 0.9851 for all six STR loci analysed and the discrimination power (DP) was 0.9999973. Therefore, this Colombian population database can be used in identity testing to estimate the frequency of a multiple PCR-based locus DNA profile in forensic cases as well as in paternity testing.

    Aim: To identify pleiotropic quantitative trait loci (QTL) influencing bone size (BS) at different skeletal sites in Caucasians. Methods: In a sample containing 3899 Caucasians from 451 pedigrees, 410 microsatellite markers spaced ~8.9 cM apart across the human genome were genotyped. Phenotypical and genetic corre-lations of BS at lumbar spine, hip (femoral neck, trochanter, and intertrochanter regions), and wrist (ultradistal, mid-distal, and one-third distal sites) were deter-mined using bivariate quantitative genetic analysis. A principal component analy-sis (PCA) was performed to obtain principal component (PC) factors that were then subjected to variance components linkage analysis to identify regions linked to the PC. Results: Genetic correlations of BS at different skeletal sites ranged from 0.40 to 0.79 (P<0.001). The PCA yielded a PC named Pctotal, which explained up to 76% of the total (co)variation of all the BS at the 7 skeletal sites for the whole sample. We identified a QTL influencing the BS of multiple skeletal sites on chromo-some 7 at 140 cM [logarithm of odds (LOD)=2.85] in the overall sample. Sex-specific evidence for linkage was observed on chromosome 11 at 53 cM (LOD =2.82) in the male-only data subset. Conclusion: Our study identified several genomic regions that may have pleiotropic effects on different skeletal sites. These regions may contain genes that play a critical role in overall bone development and osteoporo-sis at multiple skeletal sites, hence are biologically and clinically important.

    How African American hair fragility relates to hair care practices and biologic differences between races is not well understood. To assess the differences between perceptions of hair health, hair care practices, and several biologic hair parameters between Caucasian and African American women. A questionnaire on perceptions of hair health and hair care practices was administered. Biological and structural parameters of hair shaft and scalp, including growth, density, diameter, cycle, breakage, and scalp blood flow were also assessed in this case-control study. Significant differences between the Caucasian and African American women were observed in the questionnaire and biologic study data. Regarding self-reported perceptions of hair health, there were differences in the following: hair shaft type (P hair breakage (P = 0.040), and desire to change hair (P = 0.001). Regarding self-reported hair care practices, there were differences in the following: location of haircutting (P = 0.002) and washing (P = 0.010), washing frequency (P hair dryer use (P hair shaft conditioner use (P = 0.005). The two groups had similar practices in regard to the use of hair color, frequency of hair color use, chemical curling agents, and handheld blow dryer use. Regarding biological and structural parameters, there were differences in the following: hair growth rate (P hairs (P hair cycle parameters.The differences in hair care practices and hair fiber morphology among African American women may contribute to clinically observed variation in hair fragility and growth.

    Diabetic retinopathy (DR) is a common chronic complication of diabetes and remains the leading cause of blindness in working-aged people. Hyperglycemia increases glucose flux through the polyol pathway, in which aldose reductase converts glucose into intracellular sorbitol, which is subsequently converted to fructose by sorbitol dehydrogenase (SDH). The accelerated polyol pathway triggers a cascade of events leading to retinal vascular endothelial dysfunction and the eventual development of DR. Polymorphisms in the gene encoding aldose reductase have been consistently associated with DR. However, only two studies have analyzed the relationship between polymorphisms in the gene encoding SDH (SORD) and DR. In this case-control study, we investigated whether the -888G > C polymorphism (rs3759890) in the SORD gene is associated with the presence or severity of DR in 446 Caucasian-Brazilians with type 2 diabetes (241 subjects with and 205 subjects without DR). The -888G > C polymorphism was also examined in 105 healthy Caucasian blood donors, and the genotyping of this polymorphism was carried out by real-time PCR. The genotype and allele frequencies of the -888G > C polymorphism in patients with type 2 diabetes were similar to those of blood donors (G allele frequency = 0.16 in both groups of subjects). Similarly, the genotype and allele frequencies in patients with DR or the proliferative form of DR were similar to those of patients without this complication (P > 0.05 for all comparisons). Thus, our findings suggest that the -888G > C polymorphism in the SORD gene is not involved in the pathogenesis of DR in type 2 diabetes.

    This study's primary purpose was to examine the relative contribution of social-behavioral predictors to reading and math skills. The study expands on Duncan et al.'s (2007) work by using longitudinal methodology from the National Institute of Child Health and Human Development's Study of Child Care and Youth Development (SECCYD) and the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K) databases, and by focusing on potential differences in patterns of early predictors of later reading and math trajectories for African American versus Caucasian students. Predictor measures were selected at kindergarten, and the outcomes included standardized reading and math scores obtained from Grades 1, 3, 5, and 9 for the SECCYD sample, and Grades 3, 5, and 8 for the ECLS-K sample. Consistent with Duncan et al.'s findings, results reflect the relative contributions of early reading and math skills to later functioning in these respective academic domains for both samples, and there are indications for the importance of early expressive language skills to both reading and math in the SECCYD sample. Findings related to the power of social-behavioral predictors, however, are not consistent across samples. Although the SECCYD sample evidenced no such predictors, several interactions in the ECLS-K sample suggested the moderating effects of early ratings of aggressive behaviors and internalizing behaviors on later reading and math for African American students. The moderating effects of early teacher ratings of attention and internalizing behaviors for African American students as compared with Caucasian students in later math growth also were noted. The importance of early social-behavioral functions as related to later academic skills remains an important area of inquiry.

    Together with race, stature and age, sex is a main component of the biological identity. Thanks to its proportional correlation with parts of the human body, sex can be evaluated form the skeleton. The most accurate approach to determine sex by bone size is based on os coxae or skull. After natural disaster their presence can never be guaranteed, therefore the development of methods of sex determination using other skeletal elements can result crucial. Herein, sexual dimorphism in the human scapula is used to develop a two-variable discriminant function for sex estimation. We have enrolled 100 males and 100 females who underwent thoracic CT scan evaluation and we have estimated two scapular diameters. The estimation has been carried out by analyzing images of the scapulae of each patient after three dimensional post-processing reconstructions. The two-variable function allows to obtain an overall accuracy of 88% on the calibration sample. Furthermore, we have employed the mentioned function on a collection of 10 individual test sample from the collection of the "Museo di Anatomia Umana di Firenze" of the Università degli Studi di Firenze; sex has been correctly predicted on 9 skeletons.

    Indo-Asians in the UK are at an increased risk of coronary artery disease (CAD); this may be a reflection of their cardiovascular risk factor profile as well as of a more sedentary lifestyle. We hypothesised that Indo-Asians in Malaysia and the UK may exhibit a similar cardiovascular risk factor and physical activity profile, which would be more adverse compared with caucasians. We studied 70 consecutive Indo-Asian patients admitted to hospitals in Kuala Lumpur, Malaysia (n=42; 35 males; mean age 60.6 years, SD 11.8); and Birmingham, England (n=28; 20 males; mean age 60.8 years, SD 12.9). Both groups of Indo-Asian patients were compared with 20 caucasian patients (13 males; mean age 62.7 years, SD 9.4) admitted with myocardial infarction from Birmingham. There was a higher prevalence of diabetes among Indo-Asians in both countries than among caucasians (p=0.0225). By contrast, caucasians had a higher prevalence of hypercholesterolaemia (p=0.0113), peripheral vascular disease (p=0.0008), regular alcohol consumption (pMalaysia and the UK, may in part contribute to the high incidence of CAD in this ethnic group.

    This study aims to (a) examine the roles of knowledge, distrust in medical professionals, information sources, and 2 dimensions of religiosity (i.e., religious activity and religious belief) in influencing willingness to participate (WTP) in cancer clinical trials and to (b) compare the results for Caucasians and African Americans in order to inform future recruitment. An online survey was fielded via a Knowledge Networks panel with a nationally representative sample including 478 Caucasians and 173 African Americans. The results showed that distrust in medical professionals was a strong barrier to WTP for both ethnic groups, whereas factual knowledge about trial procedures was not associated with WTP for either ethnic group. Seeking trial information from doctors was positively associated with WTP for Caucasians; seeking trial information from hospitals was positively associated with WTP for African Americans. More interestingly, levels of religious activity negatively predicted WTP for Caucasians but positively predicted WTP for African Americans. Self-reported religious belief was not associated with WTP for either ethnic group. In sum, although distrust is a common barrier to WTP, the influence of preferred information sources and religious activity on WTP varies as a function of ethnicity.

    Aspects of the female body may be attractive because they signal evolutionary fitness. Greater body fatness might reflect greater potential to survive famines, but individuals carrying larger fat stores may have poor health and lower fertility in non-famine conditions. A mathematical statistical model using epidemiological data linking fatness to fitness traits, predicted a peaked relationship between fatness and attractiveness (maximum at body mass index (BMI) = 22.8 to 24.8 depending on ethnicity and assumptions). Participants from three Caucasian populations (Austria, Lithuania and the UK), three Asian populations (China, Iran and Mauritius) and four African populations (Kenya, Morocco, Nigeria and Senegal) rated attractiveness of a series of female images varying in fatness (BMI) and waist to hip ratio (WHR). There was an inverse linear relationship between physical attractiveness and body fatness or BMI in all populations. Lower body fat was more attractive, down to at least BMI = 19. There was no peak in the relationship over the range we studied in any population. WHR was a significant independent but less important factor, which was more important (greater r2) in African populations. Predictions based on the fitness model were not supported. Raters appeared to use body fat percentage (BF%) and BMI as markers of age. The covariance of BF% and BMI with age indicates that the role of body fatness alone, as a marker of attractiveness, has been overestimated. PMID:26336638

    Full Text Available Abstract Background Polycystic ovary syndrome (PCOS is the most common chronic endocrine disorder affecting women of reproductive age. This study aimed to compare the HRQoL of South Asian and white Caucasian women with PCOS, given that it is particularly common among women of South Asian origin and they have been shown to have more severe symptoms. Methods The Polycystic Ovary Syndrome Questionnaire (PCOSQ and the Short Form-36 (SF-36 were administered in a cross-sectional survey to 42 South Asian and 129 Caucasian women diagnosed with PCOS recruited from the gynaecology outpatient clinics of two university teaching hospitals in Sheffield and Leeds. Additional clinical data was abstracted from medical notes. Normative data, collected as part of the Oxford Health and Lifestyles II survey, was obtained to compare SF-36 results with ethnically matched women from the general UK population. Using the SF-36, normative HRQoL scores for women of South Asian origin were lower than for Caucasian women. Given this lower baseline we tested whether the same relationship holds true among those with PCOS. Results Although HRQoL scores for women with PCOS were lower than normative data for both groups, South Asian women with PCOS did not have poorer HRQoL than their Caucasian counterparts. For both the SF-36 and PCOSQ, mean scores were broadly the same for both Asian and Caucasian women. For both groups, the worst two HRQoL domains as measured on the PCOSQ were 'infertility' and 'weight', with respective scores of 35.3 and 42.3 for Asian women with PCOS compared to 38.6 and 35.4 for Caucasian women with PCOS. The highest scoring domain for South Asian women with PCOS was 'menstrual problems' (55.3, indicating best health, and was the only statistically significant difference from Caucasian women (p = 0.01. On the SF-36, the lowest scoring domain was 'Energy & Vitality' for Caucasian women with PCOS, but this was significantly higher for Asian women with PCOS (p

  15. Relationship between the cytotoxin-associated gene-A status of H pylori strains and cerebral infarction in European Caucasians and Chinese Han: A meta-analysis

    2008-01-01

    AIM: To study the relationship between the cytotoxin associated gene-A (CagA) status of H pylori strains and cerebral infarction among European Caucasians and Chinese Han by conducting a meta-analysis. METHODS: Ten case-control studies, with data on a total of 907 cases and 966 controls, were retrieved and considered; disqualified studies were excluded. The included studies were then tested for heterogeneity, and a meta-analysis was performed. RESULTS: The combined data revealed CagA-bearing strains of H pylori which cause chronic infection are associated with an increased risk of cerebral infarction (OR=2.66,95% CI:2. 17-3.26),but no such relationship was found with CagA-negative strains (OR =0.74,95% CI:0.49-1.10) in the overall population. We performed subgroup analyses, dividing the overall population into European Caucasians and Chinese Hart subgroups, and analyzed the studies according to their subgroup classification. Through the subgroup analysis, an association between cerebral infarction and CagA bearing strains was found in both subgroups (OR=2.60,95% CI:1.93-3.49 in Chinese Han; OR=2.71,95% CI:2.05-3.59 in European Caucasians),but no significant association was found between cerebral infarction and CagA-negative strains (OR=0.81,95% CI:0.45-1.48 in Chinese Han; OR=0.64,95% CI:0.37-1.09 in European Caucasians). CONCLUSION: These results suggest CagA-bearing strains of Hpylori are significantly associated with susceptibility to cerebral infarction in Chinese Han and European Caucasians, but that CagA-negative strains are not a definite predisposing factor in either subgroup. The magnitude of this association with cerebral infarction needs to be confirmed by prospective studies and combined studies of H pylori eradication.

    Full Text Available It is well documented that regular physical activity has a beneficial effect on human health by affecting the metabolic processes that are of fundamental importance in the body’s functions, such as insulin sensitivity and glucose disposal, as well as lipid and lipoprotein turnover. On the other hand, there is a wealth of studies which indicate that strenuous, regular physical activity, such as that performed by high performance athletes, may be detrimental for the athletes’ health especially in women. This review focuses on the factors that contribute to health problems in female athletes, named the female athlete triad, which includes excessive dieting, menstrual dysfunctions (anovulatory menstrual cycles, oligomenorrhea, amenorrhea and a low bone mineral density (BMD. As a result of these factors, women who participate in sports, especially those focused on leanness, need special attention and education from health professionals, coaches and the athletes themselves to prevent the detrimental effects of an inadequate energy supply against high energy demands.

    Tumor necrosis factor-alpha (TNF-α) inhibitors including etanercept have been demonstrated to be very effective in severe ankylosing spondylitis (AS) in Caucasian patients. However, clinical efficacy of etanercept to treat active AS in Chinese patients has not been reported. In this study, a prospective, open-label trial of etanercept (25 mg BIW), involving 46 AS patients from 16 medical centers of Taiwan, was conducted. Questionnaire was utilized to record demographic data and clinical parameters, including Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Global Index (BASGI), Assessment in Ankylosing Spondylitis (ASAS) 20, 50, and 70, and others, before and at different time intervals after etanercept treatment. Laboratory tests including blood chemistry, hematology, urine analysis, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were done at baseline and at weeks 4, 8, and 12. In this 12-week study, etanercept demonstrated rapid and significant improvement in the ASAS20 response criteria (91.3%), at as early as 2 weeks of therapy (71.3%). Partial remission of AS was achieved in 49.3% of patients after 12 weeks of treatment. Disease activity (BASDAI) and function (BASFI) were also significantly improved after 12 weeks etanercept treatment (p expansion (2.77 ± 1.69 cm versus 3.56 ± 1.82 cm, p = 0.0004) and lumbar flexion (2.11 ± 2.76 cm versus 2.58 ± 3.42 cm, p = 0.0075) and significant reduction of occiput-to-wall distance (6.59 ± 7.14 cm versus 5.32 ± 6.65 cm, p = 0.0006) were also demonstrated. Both ESR and CRP declined significantly after patients were treated with etanercept. There were no severe adverse effects during the treatment period. Etanercept is generally safe, well tolerated, and effective in Chinese patients with severe AS. Clinical efficacy, including partial remission and BASDAI, is even better in Chinese than in Caucasian patients. Further study is required to assess long-term efficacy

  19. Female-female aggression and female mate choice on black grouse leks.

    We studied female-female aggression in relation to female mate choice in black grouse, Tetrao tetrix, in central Finland, in 1994-1998. Aggression occurred on average every other minute when there was more than one female on a territory, and aggressive behaviour was most prominent when several females attended the lek. Interactions tended to be proportionally most frequent on the territories of the highest-ranking males, although not significantly so. Females that were chased by other females did not mate with lower-ranking males than their aggressors did. Furthermore, chased females were only rarely (6% of cases) forced to move off the territory by agonistic interactions and copulations were disrupted by other females even less often (3% of cases). The choice of a mating territory did not depend on the outcome of aggression even though the aggressors were more likely to mate on the territory where aggression occurred than elsewhere. There was a marginally significant tendency for aggressors to mate earlier in the season. Females placed themselves further away from other females on the territory when soliciting a copulation than just before aggression. Our results suggest that aggression between females does not effectively constrain female choice in black grouse. Its function may be to aid females to secure undisturbed mating opportunities for themselves rather than to prevent others from mating with a particular male.

    Full Text Available Abstract Background Cancer-related genes show racial differences. Therefore, identification and characterization of DNA copy number alteration regions in different racial groups helps to dissect the mechanism of tumorigenesis. Methods Array-comparative genomic hybridization (array-CGH was analyzed for DNA copy number profile in 40 Asian and 20 Caucasian lung cancer patients. Three methods including MetaCore analysis for disease and pathway correlations, concordance analysis between array-CGH database and the expression array database, and literature search for copy number variation genes were performed to select novel lung cancer candidate genes. Four candidate oncogenes were validated for DNA copy number and mRNA and protein expression by quantitative polymerase chain reaction (qPCR, chromogenic in situ hybridization (CISH, reverse transcriptase-qPCR (RT-qPCR, and immunohistochemistry (IHC in more patients. Results We identified 20 chromosomal imbalance regions harboring 459 genes for Caucasian and 17 regions containing 476 genes for Asian lung cancer patients. Seven common chromosomal imbalance regions harboring 117 genes, included gain on 3p13-14, 6p22.1, 9q21.13, 13q14.1, and 17p13.3; and loss on 3p22.2-22.3 and 13q13.3 were found both in Asian and Caucasian patients. Gene validation for four genes including ARHGAP19 (10q24.1 functioning in Rho activity control, FRAT2 (10q24.1 involved in Wnt signaling, PAFAH1B1 (17p13.3 functioning in motility control, and ZNF322A (6p22.1 involved in MAPK signaling was performed using qPCR and RT-qPCR. Mean gene dosage and mRNA expression level of the four candidate genes in tumor tissues were significantly higher than the corresponding normal tissues (PP=0.06. In addition, CISH analysis of patients indicated that copy number amplification indeed occurred for ARHGAP19 and ZNF322A genes in lung cancer patients. IHC analysis of paraffin blocks from Asian Caucasian patients demonstrated that the frequency of

    Objectives. Platelet endothelial cell adhesion molecule-1 (PECAM-1) plays a key role in the transendothelial migration of circulating leukocytes during inflammation and in the maintenance of vascular endothelial integrity. We hypothesized that genetic variation in PECAM-1 gene could be associated with diabetic nephropathy (DN) and with the level of soluble PECAM-1 in Caucasians with type 2 diabetes mellitus (T2DM). Design and Methods. We analyzed the rs688 single nucleotide polymorphism of PECAM-1 gene C373G (Leu125Val) at exon 3, which encodes the first extracellular Ig-like domain that mediates the homophilic binding of PECAM-1, in 276 T2DM subjects with documented DN (cases) and 375 T2DM subjects without DN (controls), using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy. Level of plasma soluble PECAM-1 (sPECAM-1) was measured by ELISA in a subpopulation of 120 diabetics with DN. Results. We found no association between the Leu125Val polymorphism and DN in subjects with T2DM. Likewise, the Leu125Val polymorphism was not associated with serum sPECAM-1 levels in a subpopulation of 120 diabetics with DN. Conclusion. The Leu125Val polymorphism of PECAM-1 and the level of sPECAM-1 are not associated with DN in T2DM subjects of Slovenian origin.

    Lactobionic acid was first found in a Caucasian fermented milk product popularly known as "Caspian Sea yogurt" in Japan. The presence of lactobionic acid in the fermented milk was indicated by the results of both high-performance anion-exchange chromatographic analysis with pulsed amperometric detection and mass spectrometric analysis. Thereafter, the acid was purified from the yogurt and analyzed by nuclear magnetic resonance. A substantial amount of lactobionic acid was found to be accumulated in the upper layer of the yogurt, especially within 10 mm from the surface. A total of 45 mg of lactobionic acid per 100 g of the upper yogurt layer was collected after 4 d of fermentation. The annual intake of lactobionic acid in individuals consuming 100 g of the yogurt every day would be 0.5 to 1.0 g. A lactose-oxidizing bacterium was isolated from the fermented milk and was identified as Acetobacter orientalis. Washed A. orientalis cells oxidized monosaccharides such as d-glucose at considerable rates, although their activities for substrates such as lactose, maltose, and cellobiose were much lower. When A. orientalis cells were cultivated in cow's milk, they exhibited lactose-oxidizing activity, suggesting that this bacterium was the main organism involved in the production of lactobionic acid in the yogurt.

    Catecholamines, especially noradrenalin, are essential in the control of respiration and arousal. Thus, an impaired production of these neurotransmitters may contribute to the occurrence of sudden infant death syndrome (SIDS). The first step of the noradrenergic synthesis pathway is catalyzed by the enzyme tyrosine hydroxylase (TH). The TH-encoding gene contains a tetrameric short tandem repeat in intron 1 (TH01), with allele 9.3 reported to be associated with SIDS in German infants. We investigated the allelic frequency of the TH01 marker in 171 Swiss SIDS infants and 500 healthy and gender-matched Caucasian adults. In our study population, the allelic frequency of the 9.3 allele is similarly distributed in SIDS cases and controls (27.2% vs. 25.6%; p-value = 0.562). Nevertheless, the TH-encoding gene is only one of several genes involved in the noradrenergic biosynthesis pathway. Therefore, further genetic investigations are required with focus on the whole noradrenergic signaling system.

    Full Text Available Purpose. To investigate the association of birth parameters with refractive status in different age groups of Caucasian children. Materials and Methods. This cross-sectional study included 564 eyes of 282 children aged 4 to 17 years. All children underwent complete ophthalmologic examination. The children were divided into three groups according to their refractive status (emmetropia,myopia, and hyperopia, ages (4–7, 8-9, 10–12, and 13–17, and appropriateness for gestational age, respectively. Results. The mean age of the children was 9.2±2.8 (age range 4–17 years. The mean spheric equivalent was +0.3±1.7 (range: (−10.0–(+10.0 diopters. The mean birth weight and gestational age were 2681.1±930.8 grams (750–5000 grams and 37.2±3.7 weeks (25–42 weeks. According to multinominal logistic regression analysis, children with myopia were more likely to have higher birth weights than emmetropic children (OR: 1.0, 95% CI: 1.000–1.001, and P=0.028. The hypermetropes were found to be significantly small for gestational age between 13 and 17 years of age. Conclusion. Birth weight and appropriateness for gestational age as birth parameters may have an impact on development of all types of refractive errors. The hypermetropic children tended to be small for gestational age.

    Full Text Available Abstract Background Strong epidemiologic evidence correlates tobacco use with a variety of serious adverse health effects, but the biological mechanisms that produce these effects remain elusive. Results We analyzed gene transcription data to identify expression spectra related to tobacco use in circulating leukocytes of 67 Caucasian male subjects. Levels of cotinine, a nicotine metabolite, were used as a surrogate marker for tobacco exposure. Significance Analysis of Microarray and Gene Set Analysis identified 109 genes in 16 gene sets whose transcription levels were differentially regulated by nicotine exposure. We subsequently analyzed this gene set by hyperclustering, a technique that allows the data to be clustered by both expression ratio and gene annotation (e.g. Gene Ontologies. Conclusion Our results demonstrate that tobacco use affects transcription of groups of genes that are involved in proliferation and apoptosis in circulating leukocytes. These transcriptional effects include a repertoire of transcriptional changes likely to increase the incidence of neoplasia through an altered expression of genes associated with transcription and signaling, interferon responses and repression of apoptotic pathways.

    We have identified a population of Caucasians with a defined past history of infection with Plasmodium vivax malaria. Using purified synthetic peptides overlapping the sequence of the circumsporozoite protein, we determined the percentage of individuals whose T cells proliferated or secreted IFN-gamma in response to peptide stimulation, for both this population and a population of nonmalaria-exposed control individuals. A number of peptides were recognized by both groups, but 11 peptides were uniquely recognized by the exposed population, and thus represented malaria-specific T cell epitopes. CD4 T cells were found to be responsible for the proliferative response. Humans last exposed to vivax sporozoites as long ago as 49 yr responded as well or better to these malaria-specific epitopes as individuals exposed within the previous month. Since such malaria-induced memory response may not be a feature of Plasmodium falciparum infections, and since P. falciparum does not have a persisting hypnozoite stage, our data argue that the persistence of T cell memory to vivax epitopes may result from antigenic persistence in the liver.

    Gnathodiaphyseal dysplasia (GDD; MIM#166260) is an autosomal dominant syndrome with characteristic cemento-osseous lesions of jawbones, bone fragility, and diaphyseal sclerosis of tubular bones. To date, only five mutations in the proposed calcium-activated chloride channel ANO5/TMEM16E gene have been identified. In this study, we describe two families and two singular patients with three new mutations. One Caucasian family with seven affected members exhibited frequent bone fractures and florid osseous dysplasia (p.Cys356Tyr), while one Chinese family with two affected members suffered from cementoma and purulent osteomyelitis (p.Cys360Tyr). In addition, two different novel mutations (p.Gly518Glu and p.Arg215Gly) were identified in sporadic patients without family history. In vitro studies overexpressing GDD mutations (p.Cys356Tyr and p.Cys360Tyr) showed significantly reduced ANO5 protein. It appears that all GDD mutations known so far locate in an extracellular domain following the first transmembrane domain or in the 4th putative transmembrane domain. Both wild-type and mutant ANO5 protein localize to the endoplasmic reticulum. After Ano5 gene knock-down with shRNA in MC3T3-E1 osteoblast precursors we saw elevated expression of osteoblast-related genes such as Col1a1, osteocalcin, osterix and Runx2 as well as increased mineral nodule formation in differentiating cells. Our data suggest that ANO5 plays a role in osteoblast differentiation. PMID:28176803

    Although neighborhood disadvantage has been linked to the development of cardiovascular disease, the mechanism through which living in impoverished neighborhoods is associated with poor cardiovascular health is not well understood. Additionally, it is not clear whether individual socioeconomic status (SES) interacts with neighborhood factors to influence cardiovascular outcomes. Using multilevel modeling, we examined the interaction between neighborhood poverty and individual SES on pressor responses to an alpha agonist, phenylephrine (PE), in an adult sample of 105 African-Americans and 106 Caucasian-Americans. Neighborhood poverty was assessed using census block data gathered from the Census Bureau. Education and occupation were used to assess individual SES. Pressor responsiveness was calculated as the systolic and diastolic blood pressure (BP) response to a 100-microg PE bolus administered intravenously. There was a significant interaction between education and neighborhood poverty on pressor responses. Higher education was associated with smaller BP responses to PE; but only in individuals who lived in neighborhoods in which less than 5% of the residents lived below the poverty line. Occupation was unrelated to pressor responses to PE. These results suggest that neighborhood characteristics play an important role in cardiovascular functioning.

    Participation of adolescents and young women in strenuous sports activity may lead to various metabolic and psychological derangements of clinical relevance to the endocrinologist. The most common manifestations encountered in practice are primary and secondary amenorrhea, reduced bone mineral density and eating disorders. The occurrence of all three together has been named "the athletic triad". The underlying hormonal drivers that lead to some of these manifestations are the reduced leptin level as well as the persistent low grade stress response commonly observed in such females. "Exercise-related female reproductive dysfunction" (ERFRD), can possibly include short-term (infertility) and long-term (osteoporosis) consequences. Functional hypothalamic amenorrhea, a manifestation of ERFRD in adolescence, is an integrated response to the combination of excessive physical and emotional stress, exercise, and/or reduced food intake characterized by decreased endogenous GNRH secretion. The primary aim of treating these athletes should be the prevention of the development of any component of the triad as well as the whole complex by educating athletes, trainers, parents and health care professionals about proper nutrition and safe training. The long term prognosis is good. However, significant long term morbidity may affect these young women later in life.

    Female sexual problems are common, frequently overlooked and have a significant impact on the lives of women. Research in the last decade has brought to the understanding and recognition of a number of standpoints, mainly the broad range of normative function. In 2003, the American Urological Association Foundation convened an international committee of experts in the field of women's sexuality, to reconsider the existing definitions of women's sexual dysfunction. Based on the circular response cycle developed by Basson, the group emphasized motivations that might move a woman from being sexually "neutral" to making a decision to be sexual with her partner, as a normative alternative to the need for spontaneous sexual desire as the trigger for sexual behavior. Etiology may stem from medical as well as psychological factors, thus assessment must include a complete evaluation. Treatment includes psycho-education, improvement of interpersonal communication, cognitive behavioral treatment and elucidation and treatment of medical problems, if necessary. Several pharmacological treatments are under investigation, with modest results and uncertainties about their long term safety. This review presents the female sexual response as it is understood today and the current diagnostic and therapeutic understandings and directions.

    Subclinical atherosclerosis can be quantified by coronary artery calcium (CAC) scoring. Due to its high specificity for atherosclerosis, CAC is an excellent phenotypic tool for the evaluation of emerging risk markers. Lipoprotein(a) [Lp(a)] is atherogenic due to the presence of apoB and may be thrombogenic through its apo(a) component. Lp(a) has been linked to cardiovascular events in Caucasians; however, its link to atherosclerosis in various ethnicities remains unclear. We evaluated the ability of Lp(a) mass to predict subclinical atherosclerosis in Southeast Asians and Caucasians, as measured by CAC. Traditional lipid measurements, Lp(a) measurements, and CAC by 64-slice multidetector computed tomography was performed in 103 consecutive patients in the USA and in 104 consecutive patients in Jakarta, Indonesia. Proportion of positive CAC and median CAC in Southeast Asians and in Caucasians was 61.5% and 63.1%, and 23.5 (interquartile range, 0-270) and 13 (interquartile range, 0-388), respectively. Significantly higher proportion of Southeast Asians had elevated Lp(a) levels, compared to Caucasians (51.0% vs. 29.2%; p = 0.005). In Southeast Asians, Lp(a) remained an independent predictor of CAC with an odds ratio of 4.97 (95% confidence interval, 1.56-15.88; p Southeast Asians. This translated to 7% of Southeast Asians reclassified to correct CAC status. Lp(a) measurements may have a role in risk stratification of Southeast Asians. Ethnic variation should be taken into account when considering the use of Lp(a) measurements in risk assessment.

    The practitioner, as well as specialist such as gynecologist and endocrinologist, may face in their office women with eating disorders, abnormalities of menstrual cycles and low bone mass, which may be the first hints of the female athlete triad. In these situations, the practitioner may search other findings of these triad by looking at some particular physical findings and by using appropriate questionnaire. In some advanced forms of this triad specific abnormalities of eating disorders (anorexia and boulimia) may be present as well as amenorrhea and osteoporosis, which may disturb the well-being and cause health damages of women practising sport either as amateur or in a elite setting. An appropriate handling of such disorders has to be proposed to these women.

    Full Text Available Introduction. We study whether the relationship between neighborhood social environment and maternal communication with healthcare providers differs between Asians and Caucasians. Method and Materials. Using the 2007 Los Angeles Mommy and Baby (LAMB survey, we measure new mother’s neighborhood social environment by four key variables: (1 instrumental/emotional support during pregnancy, (2 neighborhood social cohesion, (3 neighborhood social exchange, and (4 neighborhood services. Logistic regressions were applied for data analysis. Neighborhood social exchange predicts less chance of lacking communication about sensitive issues in preconception visits among Caucasians (logged odds: −0.045; P<0.01 and Asians (L.O.: −0.081; P<0.001 and predicts less chance of lacking communication during preconception visits among Asians (L.O.: −0.092; P<0.05. Neighborhood social cohesion predicts more chance for lacking communication about preparation for pregnancy only among Asians (L.O.: 0.065; P<0.05. Neighborhood services predict less chance of lacking communication about stigmatized issues in the prenatal visit among Asians (L.O.: −0.036; P<0.05. Discussion. Caucasians and Asians with more neighborhood social exchange are more likely to discuss sensitive issues during preconception visits. Neighborhood service significantly predicts maternal discussion of stigmatized issues with health care providers, but only among Asians.

    Kinesiology departments have recently started to offer allied health education programs to attract additional students to teacher education units (9). Although allied health professions offer increased work opportunities, insufficient enrollment and training of minority students in these academic fields contribute to underrepresentation in the workforce (3). To improve workforce diversity, kinesiology departments must understand how enrollment influences and barriers differ by race among prospective students. Therefore, the purpose of this study was to identify differences in allied health education enrollment influences and enrollment barriers between minority and Caucasian students. Participants (n = 601) consisted of students enrolled in kinesiology-based allied health education programs. Multivariate ANOVA was used to compare group differences in enrollment decision making. "Personal influence," "career opportunity," and "physical self-efficacy" were all significantly stronger enrollment influences among African-American students than among Caucasian students, and "social influence," "experiential opportunity," "academic preparation," and "physical self-efficacy" were all perceived as significantly greater barriers compared with Caucasian students. Findings support the need to recruit African-American students through sport and physical education settings and to market program-based experiential opportunities.

Student t test and standard deviation test were applied. Results There was a predominance of endonasal access (94.4%). The most common dorsum technique was hump removal (33.33%), and the predominance of sutures (24.76%) was observed on the nasal tip, with the lateral intercrural the most frequent (32.39%). Comparison between preoperative and postoperative photos found statistically significant alterations on the anthropometric measurements of the noses. Conclusion The main surgical techniques on Caucasian noses were evaluated, and a great variety was found. The evaluation of anthropometric measurements of the nose proved the efficiency of the performed procedures. PMID:25992149

    Full Text Available Introduction In contrast to animal species in which linear relationships exist between hormonal status and sexual behaviour sexuality in human population is not determined so simply by the level of sexual steroids. The article analyses female sexuality in the light of hormonal status. Administration of sexual steroids during pregnancy and sexual differentiation High doses of gestagens, especially those with high androgen activity, widely used against miscarriages may lead to tomboys, but without differences in sexual orientation. However, it has been observed that the frequency of bisexual and lesbian women is higher in women with congenital adrenogenital syndrome. Hormones sexual desire and sexuality during menstrual cycle It has been established that sexual desire, autoeroticism and sexual fantasies in women depend on androgen levels. There are a lot of reports claiming that sexual desire varies during the menstrual cycle. Hormonal contraception and sexuality Most patients using birth control pills present with decreased libido. But, there are reports that progestagens with antiandrogenic effect in contraceptive pills do not affect sexual desire. Hormonal changes in peri- and postmenopausal period and sexuality Decreased levels of estrogen and testosterone in older women are associated with decreased libido, sensitivity and erotic stimuli. Sexuality and hormone replacement therapy Hormonal therapy with estrogen is efficient in reference to genital atrophy, but not to sexual desire. Really increased libido is achieved using androgens. Also, therapy with dehydroepiandrosterone (DHEA and tibolone have positive effects on female libido. Conclusion Effect of sexual steroids on sexual sphere of women is very complex. The association between hormones and sexuality is multidimensional, as several hormones are important in regulation of sexual behaviour. Still, it should be pointed out that sexuality is in the domain of hormonal, emotional

    , exposure to science, parent influence, peer influence, teacher expectations, strategies for academic success in science, and perception of self in a predominantly Caucasian population. This information should be used to create interactive suburban middle school science classrooms that encourage the participation of African American females. These females should experience increased involvement with activities that expose them to science that is relevant to their lives. As a result, these females will be inspired to excel in science and one day enter into science careers.

    Full Text Available BACKGROUND: The thyroid stimulating hormone receptor (TSHR gene is an established susceptibility locus for Graves' disease (GD, with recent studies refining association to two single nucleotide polymorphisms (SNPs, rs179247 and rs12101255, within TSHR intron 1. METHODOLOGY AND PRINCIPAL FINDINGS: We aimed to validate association of rs179247 and rs12101255 in Polish and UK Caucasian GD case-control subjects, determine the mode of inheritance and to see if association correlates with specific GD clinical manifestations. We investigated three case-control populations; 558 GD patients and 520 controls from Warsaw, Poland, 196 GD patients and 198 controls from Gliwice, Poland and 2504 GD patients from the UK National collection and 2784 controls from the 1958 British Birth cohort. Both rs179247 (P = 1.2×10(-2-6.2×10(-15, OR = 1.38-1.45 and rs12101255 (P = 1.0×10(-4-3.68×10(-21, OR = 1.47-1.87 exhibited strong association with GD in all three cohorts. Logistic regression suggested association of rs179247 is secondary to rs12101255 in all cohorts. Inheritance modeling suggested a co-dominant mode of inheritance in all cohorts. Genotype-phenotype correlations provided no clear evidence of association with any specific clinical characteristics. CONCLUSIONS: We have validated association of TSHR intron 1 SNPs with GD in three independent European cohorts and have demonstrated that the aetiological variant within the TSHR is likely to be in strong linkage disequilibrium with rs12101255. Fine mapping is now required to determine the exact location of the aetiological DNA variants within the TSHR.

    Studies investigating the association between cytochrome P450 1B1 (CYP1B1) Leu432Val (432 C/G, rs1056836) polymorphism and colorectal cancer (CRC) risk report conflicting results. The aim of this study was to quantitatively summarize the evidence for such a relationship. Two investigators independently searched the Medline, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine Databases. Summary odds ratios (ORs) and 95% confidence intervals (95% CIs) for CYP1B1 polymorphism and CRC were calculated in a fixed-effects model and a random-effects model when appropriate. The pooled ORs were performed for co-dominant model (GG vs. CC, GC vs. CC), dominant model (GG + GC vs. CC), and recessive model (GG vs. GC + CC). This meta-analysis included ten case-control studies, which included 8,466 CRC cases and 9,301 controls. Overall, the variant genotypes (GG and GC) of the 432 C/G were not associated with CRC risk when compared with the wild-type CC homozygote (GG vs. CC, OR = 1.01, 95% CI = 0.93-1.10; GC vs. CC, OR = 0.97, 95% CI = 0.90-1.04), without any between-study heterogeneity. Similarly, no associations were found in the dominant and recessive models (dominant model, OR = 0.98, 95% CI = 0.92-1.05; recessive model, OR = 1.03, 95% CI = 0.96-1.11). Limiting the analysis to the studies within Hardy-Weinberg equilibrium, the results were persistent and robust. When stratifying for country, matched control and source of controls, no evidence of significant association was observed in any subgroup. No publication bias was found in the present study. No association is found between the CYP1B1 Leu432Val polymorphism and risk of CRC among Caucasians.

    Aging is a complex process that is accompanied with changes in both muscle mass and muscle function (strength and performance). Therefore, the current longitudinal study aimed to provide a better insight in 10-year aging-related changes in whole-body muscle mass and strength performance of the leg extensors during the adult life span. Data were gathered within the framework of the first- (2002-2004: baseline) and third-generation Flemish Policy Research Center Sport (2012-2014: follow-up). Results are based on muscle characteristics data of 591 Flemish Caucasian adults (19-73 years, 381 men). Skeletal muscle mass (SMM) was determined with bioelectrical impedance analysis. Biodex Medical System 3® dynamometer was used to measure isometric (PTstatic120°) and isokinetic (PTdynamic60° and PTdynamic240°) strength, ballistic movement speed (S 20 %), and muscular endurance (work) of the knee extensors. Overall strength performance was higher at both evaluation moments in men compared to women (p < 0.01). But only S 20 % declined significantly faster in men compared to women (p < 0.01). Age and baseline strength performance were negatively related with the change in strength performance, even when corrected for SMM, protein intake, and energy expenditure during sports (E sport). In conclusion, strength performance was not associated with E sport in this study, but protein intake was associated with isometric strength in men, and with ballistic and isokinetic strength in women. Changes in S 20 % were significantly greater in men compared to women. Baseline values of strength performance and age were associated with changes in strength performance parameters, even after correction for SMM, protein intake, and E sport.

    Full Text Available The Haplotype Map (HapMap project recently generated genotype data for more than 1 million single-nucleotide polymorphisms (SNPs in four population samples. The main application of the data is in the selection of tag single-nucleotide polymorphisms (tSNPs to use in association studies. The usefulness of this selection process needs to be verified in populations outside those used for the HapMap project. In addition, it is not known how well the data represent the general population, as only 90-120 chromosomes were used for each population and since the genotyped SNPs were selected so as to have high frequencies. In this study, we analyzed more than 1,000 individuals from Estonia. The population of this northern European country has been influenced by many different waves of migrations from Europe and Russia. We genotyped 1,536 randomly selected SNPs from two 500-kbp ENCODE regions on Chromosome 2. We observed that the tSNPs selected from the CEPH (Centre d'Etude du Polymorphisme Humain from Utah (CEU HapMap samples (derived from US residents with northern and western European ancestry captured most of the variation in the Estonia sample. (Between 90% and 95% of the SNPs with a minor allele frequency of more than 5% have an r2 of at least 0.8 with one of the CEU tSNPs. Using the reverse approach, tags selected from the Estonia sample could almost equally well describe the CEU sample. Finally, we observed that the sample size, the allelic frequency, and the SNP density in the dataset used to select the tags each have important effects on the tagging performance. Overall, our study supports the use of HapMap data in other Caucasian populations, but the SNP density and the bias towards high-frequency SNPs have to be taken into account when designing association studies.

    Alcohol addiction may increase the risk of obesity due to shared genetic components. The Copine V (CPNE5) gene is involved in Ca(2+) binding and may play an important role in the development of the central nervous system. This study tested the genetic associations of 77 single-nucleotide polymorphisms (SNPs) within the CPNE5 gene with alcohol dependence (AD) and obesity using a Caucasian sample - The Study of Addiction - Genetics and Environment (SAGE) sample (1066 AD cases and 1278 non-AD controls, 422 obese cases and 1395 non-obese controls). The Marshfield sample (1442 obese cases and 2122 non-obese controls) was used for replication of obesity. Multiple logistic regression analysis was performed using the PLINK software. In the SAGE sample, we identified 10 SNPs associated with AD and 17 SNPs associated with obesity (p obesity (OR = 0.77, 0.77, 0.78, 0.77, 0.68 and 1.18, respectively; p = 2.74 × 10(-3), 2.69 × 10(-3), 2.45 × 10(-3), 1.01 × 10(-3), 5.18 × 10(-3) and 3.85 × 10(-2), respectively). In the Marshfield sample, rs3752480 was associated with obesity (p = 0.0379). In addition, four SNPs (rs9986517, rs10456444, rs7763347 and rs4714010) showed associations with obesity in the meta-analysis using both samples (p = 0.00493, 0.0274, 0.00346, and 0.0141, respectively). These findings provide the first evidence of common genetic variants in the CPNE5 gene influencing both the AD and obesity; and will serve as a resource for replication in other populations.

    Estimation of total body height is a major step when a subject has to be identified from his/her skeletal structures. In the presence of decomposed skeletons and missing bones, estimation is usually based on regression equation for intact long bones. If these bones are fragmented or missing, alternative structures must be used. In this study, the value of sacrum height (SH) in total body height (TBH) estimation was investigated in a contemporary population of adult Anatolian Caucasians. Sixty-six men (41.6 {+-} 14.9 years) and 43 women (41.1 {+-} 14.2 years) were scanned with 64-row multidetector computed tomography (MDCT) to obtain high-resolution anthropometric data. SH of midsagittal sections was electronically measured. The technique and methodology were validated on a standard skeletal model. Sacrum height was 111.2 {+-} 12.6 mm (77-138 mm) in men and 104.7 {+-} 8.2 (89-125 mm) in women. The difference between the two sexes regarding SH was significant (p < 0.0001). SH did not significantly correlate with age in men, whereas the correlation was significant in women (p < 0.03). The correlation between SH and the stature was significant in men (r = 0.427, p < 0.0001) and was insignificant in women. For men the regression equation was [Stature = (0.306 x SH)+137.9] (r = 0.54, SEE = 56.9, p < 0.0001). Sacrum height is not susceptible to sex, or to age in men. In the presence of incomplete male skeletons, SH helps to determine the stature. This study is also one of the initial applications of MDCT in virtual anthropometric research. (orig.)

    Until recently, the women's changing room in the Fire Station, built in 2005, has always been empty. With the arrival of Séverine Peverelly, CERN's first female firefighter, it now has a purpose. Séverine Peverelly took up her post as a firefighter in April. Séverine, who comes from Gap in France, took up her post as a firefighter in the CERN fire brigade at the beginning of April. "We were looking for a new member," explains David Peyron, Head of the Fire and Rescue Service. It didn't matter if it was a man or a woman; we needed a firefighter with the right skills, and Séverine just happened to have them." With ten years experience working in French fire services, Séverine was looking for a new challenge. "What attracted me to CERN was the international dimension, because that creates additional challenges," she explains. And these can be considerable! For one thing, every country has its own way of worki...

    The World Health Organization estimates that the number of obese and overweight adults has increased to 1.6 billion, with concomitant increases in comorbidity. While genetic factors for obesity have been extensively studied in Caucasians, fewer studies have investigated genetic determinants of body mass index (BMI; weight (kg)/height (m)2) in African Americans. A total of 38 genes and 1,086 single nucleotide polymorphisms (SNPs) in African Americans (n = 1,173) and 897 SNPs in Caucasians (n = 1,165) were examined in the Southern Community Cohort Study (2002–2009) for associations with BMI and gene × environment interactions. A statistically significant association with BMI survived correction for multiple testing at rs4140535 (β = −0.04, 95% confidence interval: −0.06, −0.02; P = 5.76 × 10−5) in African Americans but not in Caucasians. Gene-environment interactions were observed with cigarette smoking and a SNP in ADIPOR1 in African Americans, as well as between a different SNP in ADIPOR1 and physical activity in Caucasians. A SNP in PPARGC1A interacted with alcohol consumption in African Americans, and a different SNP in PPARGC1A was nominally associated in Caucasians. A SNP in CYP19A1 interacted with dietary energy intake in African Americans, and another SNP in CYP191A had an independent association with BMI in Caucasians. PMID:22106445

    Prostate cancer is the most common cancer among men in the United States with striking differences in incidence and mortality among ethnic groups. Michigan has one of the largest concentrations of Arab Americans (AAs) in the U.S. and little is known about this ethnic minority with respect to prostate cancer. This study investigated differences in clinical profile, quality of care, and recurrence among prostate cancer survivors comparing AAs and Caucasian Americans (CAs). Participants in this study included 2499 prostate cancer survivors from the Michigan Cancer Registry from 1985 to 2004. Participants completed surveys regarding health-seeking behavior, post-treatment symptoms, quality of care and recurrence. Ethnicity was self-reported and AAs and CAs were compared with respect to clinical profile, quality of care, and recurrence. There were 52 AAs and 1886 CAs patients with AAs being younger ([Formula: see text] age 68.3 ± SD 21.4 years, [Formula: see text] age 72.3 ± SD 14.1 years, for AAs and CAs, respectively) (P = 0.05). AAs had lower socioeconomic standard than CAs (34 vs. 10.6 %, <$20,000 yearly income/year; for AAs vs. CAs, respectively) (P < 0.0001). AAs reported poorer health than AAs (7.7 vs. 3.0 % for AAs vs. CAs, respectively) (P < 0.0001). AAs were more likely to visit specialists for prostate follow-up (44.5 vs. 19.7 % visited a specialist, for AAs vs. CAs respectively) (P < 0.0001) and received supplementary healthcare workers (13 % of AAs vs. 3.1 % CAs) (P = 0.032). In addition, AAs reported higher occurrence of urinary incontinence compared to CAs (67.4 vs. 60.4 %, for AAs vs. CAs, respectively) (P = 0.001). Ethnic background was not a predictor of recurrence [(Odds ratio (OR) = 1.1 (95 % confidence intervals CI = 0.40, 2.9)] (P = 0.873) even after adjusting for age, PSA levels within the last 2 years, metastasis and hormonal therapy. While AAs prostate cancer patients were different from CAs in age, income

    Dual-energy X-ray (DXA) is an alternative to magnetic resonance imaging (MRI) to measure skeletal muscle mass. DXA assesses lean body mass (LBM), and MRI measures skeletal muscle mass (SMM). Kim et al. (Am J Clin Nutr 2002; 76: 378; J Appl Physiol (1985) 2004; 97: 655) developed MRI-based algorithms to estimate whole-body SMM by DXA. These algorithms were based on an ethnically mixed study population (Kim et al., Am J Clin Nutr 2002; 76: 378; J Appl Physiol (1985) 2004; 97: 655). It is unclear whether Kim's algorithms are accurate in an exclusive Caucasian population. The aim of our study was to validate Kim's equation in a Caucasian population of 346 subjects. SMMMRI was assessed using MRI, and LBM and BMCDXA were measured by DXA and fat mass (FMADP ) by air-displacement plethysmographie (ADP). SMMMRI and predicted SMM were highly correlated (r = 0·944; P<0·05). The standard error of estimate of the regression equation was 2·4 kg. However, Bland-Altman plots showed a significant (P<0·001) systematic bias between SMMMRI (median 25·1 kg; IQ 20·2-31·1 kg) and predicted SMM (median 26·3 kg; IQ 22·6-33·0 kg), overestimating SMM by 9·8%. Multiple regression analyses showed that weight explained 4·4% of the variance in the differences between SMMMRI and predicted SMM with the major part unexplained. Kim's algorithm has a systematic unexplained bias and is not recommended in Caucasians.

The pol gene was analysed by standard population sequencing and by AS-PCR for the detection of Y181C and K103N.The Y181C was detected in the minority quasispecies of six Ethiopians (6.5%, in two Caucasians (4.5%, and in one East-African (1.8%. The K103N was detected in one East- African (1.8%, by both methods. The proportion of mutants ranged from 0.25% to 17.5%. Additional DRMs were found in all three treatment naïve patient groups by population sequencing.Major NNRTI mutations can be found by AS-PCR in minor quasispecies of treatment naïve HIV-1 infected Ethiopians living in Ethiopia, in East-African and Caucasian patients living in Sweden in whom population sequencing reveal wild-type virus only. Surveys with standard sequencing are likely to underestimate transmitted drug resistance and the presence of resistant minor quasispecies in treatment naïve patients should be topic for future large scale studies.

    Historically, pepper spray product potency has been established using a taste test evaluation. A taste test is subjective and may not be appropriate for assessing pepper potency in skin. The current study evaluated chemically diverse pepper sprays in human forearm skin using three objective, noninvasive parameters: transepidermal water loss, skin surface temperature and erythema, as a means for assessing dermal pharmacology, toxicology and product potency. Five commercial pepper spray products containing various capsaicinoid analogs at various concentrations were evaluated in duplicate on volar forearms of six Caucasians and six Asians using a 10 min exposure. Mean surface skin temperature, transepidermal water loss results were highly variable and therefore did not demonstrate dose responsive behavior to increasing capsaicinoid concentrations. Erythema, as measured by increases in a* (reflected light in the red-to-green color spectrum) of the L*a*b* uniform color scale, was superior among parameters evaluated in discriminating pepper spray potency and correlated well with the relative and total capsaicinoid concentration in the products. Products containing greater than 16 mg ml(-1) capsaicinoid concentration produced greater erythema responses in Caucasians than Asians. Asians responded greater to the synthetic analog, nonivamide, than to mixtures of capsaicinoids, while Caucasians responded equally to both capsaicinoid analogs. Thus, pepper spray product potency in human skin reflects the total capsaicinoid concentration, the specific capsaicin analog(s) present, and the race of the individual exposed. The finding that the reflectance colorimeter a* scale can differentiate these parameters in skin will have a significant impact on evaluating the use and efficacy of pepper spray products in humans.

    Highlights: •We analyzed CT-features of part-solid ground glass nodules in Caucasians. •These CT-features were compared to pathology on full resection specimen. •Several CT-features can help differentiating invasive adenocarcinoma. •A solid component larger than 5 mm had 100% sensitivity for invasive adenocarcinoma. -- Abstract: Objective: To retrospectively investigate the diagnostic value of pre-operative CT-features between pre/minimally invasive and invasive lesions in part-solid persistent pulmonary ground glass nodules in a Caucasian population. Materials and methods: Retrospective review of two pre-operative CTs for 31 nodules in 30 patients. There were 10 adenocarcinomas in situ, 1 minimally invasive adenocarcinoma, 20 invasive adenocarcinomas. We analyzed the correlation between histopathology and the following CT-features: maximal axial diameter, maximal orthogonal axial diameter, height, density, size of solid component, air bronchogram, pleural retraction, nodule mass, disappearance rate and their evolution during follow-up. Results: In univariate analysis, invasive adenocarcinomas had a higher maximal height, density, solid component size, mass, a lower disappearance rate and presented more often with pleural retraction (p < 0.05). After logistic regression performed with the uncorrelated parameters using a method of selection of variables, only the size of solid component remained significant, with 100% sensitivity for invasive adenocarcinoma when larger than 5 mm. Conclusion: Preoperative CT-features can help differentiating in situ and minimally invasive adenocarcinomas from invasive adenocarcinomas in Caucasian patients. A solid component larger than 5 mm in diameter had 100% sensitivity for the diagnosis of invasive adenocarcinoma.

    Polymorphic insertion frequencies of the retrotransposons known as the "SVA" elements were investigated at four loci in the MHC class I genomic region to determine their allele and haplotype frequencies and associations with the HLA-A, -B or -C genes for 100 Japanese, 100 African Americans, 174 Australian Caucasians and 66 reference cell lines obtained from different ethnic groups. The SVA insertions representing different subfamily members varied in frequency between none for SVA-HF in Japanese and 65% for SVA-HB in Caucasians or African Americans with significant differences in frequencies between the three populations at least at three loci. The SVA loci were in Hardy-Weinberg equilibrium except for the SVA-HA locus which deviated significantly in African Americans and Caucasians possibly because of a genomic deletion of this locus in individuals with the HLA-A*24 allele. Strong linkage disequilibria and high percentage associations between the human leucocyte antigen (HLA) class I gene alleles and some of the SVA insertions were detected in all three populations in spite of significant frequency differences for the SVA and HLA class I alleles between the three populations. The highest percentage associations (>86%) were between SVA-HB and HLA-B*08, -B*27, -B*37 to -B*41, -B*52 and -B*53; SVA-HC and HLA-B*07; SVA-HA and HLA-A*03, -A*11 and -A*30; and SVA-HF and HLA-A*03 and HLA-B*47. From pairwise associations in the three populations and the homozygous cell line results, it was possible to deduce the SVA and HLA class I allelic combinations (haplotypes), population differences and the identity by descent of several common HLA-A allelic lineages.

    Full Text Available This case describes a 31-year-old female Caucasian patient with complaints of ongoing depression, agitation, and severe panic attacks. The patient was untreated until a recent unsuccessful trial of citalopram followed by venlafaxine which produced a partial response. Genetic testing was performed to assist in treatment decisions and revealed the patient to be heterozygous for polymorphisms in 5HT2C, ANK3, and MTHFR and homozygous for a polymorphism in SLC6A4 and the low activity (Met/Met COMT allele. In response to genetic results and clinical presentation, venlafaxine was maintained and lamotrigine was added leading to remission of agitation and depression.

    ABSTRACT Urinary incontinence is a common problem among women and it is estimated that between 15 and 55% of them complain of lower urinary symptoms. The most prevalent form of urinary incontinence is associated with stress, followed by mixed urinary incontinence and urge urinary incontinence. It is a symptom with several effects on quality of life of women mainly in their social, familiar and sexual domains. Female reproductive and urinary systems share anatomical structures, which promotes that urinary problems interfere with sexual function in females. This article is a review of both the concepts of female urinary incontinence and its impact on global and sexual quality of life. Nowadays, it is assumed that urinary incontinence, especially urge urinary incontinence, promotes anxiety and several self-esteem damages in women. The odour and the fear of incontinence during sexual intercourse affect female sexual function and this is related with the unpredictability and the chronicity of incontinence, namely urge urinary incontinence. Female urinary incontinence management involves conservative (pelvic floor muscle training), surgical and pharmacological treatment. Both conservative and surgical treatments have been studied about its benefit in urinary incontinence and also the impact among female sexual function. Unfortunately, there are sparse articles that evaluate the benefits of female sexual function with drug management of incontinence. PMID:28124522

    "Female genital circumcision" or "female genital mutilation", as it is called more often, is an operation that is primarily carried out in Africa. Owing to migration, physicians are increasingly confronted with this issue in Western countries as well. A range of negative effects may result from this operation and this article aims to address consequences for female pelvic health. Special emphasis is placed on urogynaecological health consequences; in particular, on "voiding difficulties", "recurrent urinary tract infections" and "vesicovaginal fistula". All of these occur mostly in infibulated women, i.e. in women whose genitalia are sealed by the most severe form of circumcision. Some of the problems that may emerge as a result of the operation can be resolved by defibulation (i.e. surgical reopening of the sealed vulva). Female genital circumcision is a sensitive topic even in the area of research and reliable data are therefore scarce.

    Cryptic female choice (CFC) represents postmating intersexual selection arising from female-driven mechanisms at or after mating that bias sperm use and impact male paternity share. Although biologists began to study CFC relatively late, largely spurred by Eberhard's book published 20 years ago, the field has grown rapidly since then. Here, we review empirical progress to show that numerous female processes offer potential for CFC, from mating through to fertilization, although seldom has CFC been clearly demonstrated. We then evaluate functional implications, and argue that, under some conditions, CFC might have repercussions for female fitness, sexual conflict, and intersexual coevolution, with ramifications for related evolutionary phenomena, such as speciation. We conclude by identifying directions for future research in this rapidly growing field.

    Female smokers often have higher levels of eating disorder symptoms than non-smokers, and concerns about eating and weight might interfere with smoking cessation. Thus, it is critical to identify factors to promote healthier eating and body image in this population. Initial research suggests that specific aspects of trait mindfulness predict lower body dissatisfaction and eating disorder symptoms among non-smokers. However, these relationships are unknown among smokers. The current study examined associations between facets of trait mindfulness and eating disorder symptoms in 112 college female smokers (83% Caucasian; mean age 20 years, SD=1.69). After controlling for relevant sociodemographic variables, Describing and Nonjudging facets of mindfulness predicted lower bulimic symptoms and body dissatisfaction (psmindfulness facets are related to lower eating disorder symptoms among smokers, whereas other facets are not associated or have a positive relationship with these symptoms. Mindfulness-based interventions focusing on Describing, Nonjudging, and Acting with Awareness may help to reduce eating pathology among female smokers, which could potentially improve smoking cessation rates in this population.

    The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C.

    China is a region of the world with a rapidly spreading HIV-1 epidemic. Studies providing insights into HIV-1 pathogenesis in infected Chinese are urgently needed to support the design and testing of an effective HIV-1 vaccine for this population. HIV-1-specific T cell responses were characterized in 32 HIV-1-infected individuals of Chinese origin and compared to 34 infected caucasians using 410 overlapping peptides spanning the entire HIV-1 clade B consensus sequence in an IFN-gamma ELISpot assay. All HIV-1 proteins were targeted with similar frequency in both populations and all study subjects recognized at least one overlapping peptide. HIV-1-specific T cell responses clustered in seven different regions of the HIV-1 genome in the Chinese cohort and in nine different regions in the caucasian cohort. The dominant HLA class I alleles expressed in the two populations differed significantly, and differences in epitope clustering pattern were shown to be influenced by differences in class I alleles that restrict immunodominant epitopes. These studies demonstrate that the clustering of HIV-1-specific T cell responses is influenced by the genetic HLA class I background in the study populations. The design and testing of candidate vaccines to fight the rapidly growing HIV-1 epidemic must therefore take the HLA genetics of the population into account as specific regions of the virus can be expected to be differentially targeted in ethnically diverse populations.

    Allele distributions for 13 tetrameric short tandem repeat (STR) loci, CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, and D21S11, were determined in African American, United States Caucasian, Hispanic, Bahamian, Jamaican, and Trinidadian sample populations. There was little evidence for departures from Hardy-Weinberg expectations (HWE) in any of the populations. Based on the exact test, the loci that departed significantly from HWE are: D21S11 (p = 0.010, Bahamians); CSF1PO (p = 0.014, Trinidadians); TPOX (p = 0.011, Jamaicans and p = 0.035, U.S. Caucasians); and D16S539 (p = 0.043, Bahamians). After employing the Bonferroni correction for the number of loci analyzed (i.e., 13 loci per database), these observations are not likely to be significant. There is little evidence for association of alleles between the loci in these databases. The allelic frequency data are similar to other comparable data within the same major population group.

    Fruit and vegetables contain carotenoid pigments, which accumulate in human skin, contributing to its yellowness. This effect has a beneficial impact on appearance. The aim was to evaluate associations between diet (fruit, vegetable and dietary carotenoid intakes) and skin color in young women. Ninety-one Caucasian women (Median and Interquartile Range (IQR) age 22.1 (18.1-29.1) years, BMI 22.9 (18.5-31.9) kg/m2) were recruited from the Hunter region (Australia). Fruit, vegetable and dietary carotenoid intakes were estimated by a validated food frequency questionnaire. Skin color was measured at nine body locations (sun exposed and unexposed sites) using spectrophotometry. Multiple linear regression was used to assess the relationship between fruit and vegetable intakes and skin yellowness adjusting for known confounders. Higher combined fruit and vegetable intakes (β = 0.8, p = 0.017) were associated with higher overall skin yellowness values. Higher fruit combined fruit and vegetable intakes (β = 1.0, p = 0.004) were associated with increased unexposed skin yellowness. Combined fruit and vegetables plus dietary carotenoid intakes contribute to skin yellowness in young Caucasian women. Evaluation of interventions using improvements in appearance as an incentive for increasing fruit and vegetable consumption in young women is warranted.

    The presentation, natural history, clinical outcomes, and response to therapy in patients with heart failure differ in some ways across populations. Women, older adults, and non-Caucasian racial or ethnic groups compose a substantial proportion of the overall heart failure population, but they have typically been underrepresented in clinical trials. As a result, uncertainty exists about the efficacy of some guideline-directed medical therapies and devices in specific populations, which may result in the under- or overtreatment of these patients. Even when guideline-based treatments are prescribed, socioeconomic, physical, or psychologic factors may affect non-Caucasian and older adult patient groups to a different extent and affect the application, effectiveness, and tolerability of these therapies. Individualized therapy based on tailored biology (genetics, proteomics, metabolomics), socioeconomic and cultural considerations, and individual goals and preferences may be the optimal approach for managing diverse patients. This comprehensive approach to personalized medicine is evolving, but in the interim, the scientific community should continue efforts focused on intensifying research in special populations, prescribing guideline-directed medical therapy unless contraindicated, and implementing evidence-based strategies including patient and family education and multidisciplinary team care in the management of patients.

    This study was designed to summarize quantitatively the evidence for a relationship between collagen type I alpha1 (COLIA1) Sp1 polymorphism and osteoporotic fracture risk in Caucasian post-menopausal women. This meta-analysis included 16 studies, which analysed 2294 patients with fractures and 10 285 controls. The combined results showed that there was a significant difference in genotype distribution (SS odds ratio [OR] 0.72; Ss OR 1.18; ss OR 1.97) between patients with fractures and controls. When stratifying by the fracture site, it was found that: (i) patients with vertebral fractures had a significantly higher frequency of the Ss genotype and a lower frequency of the SS genotype than controls; and (ii) patients with non-vertebral fractures had a significantly higher frequency of the ss genotype and a lower frequency of the SS genotype than controls. This meta-analysis suggests that the COLIA1 Sp1 polymorphism may be associated with osteoporotic fracture in Caucasian post-menopausal women.

  1. Quantitative and Qualitative Responses to Topical Cold in Healthy Caucasians Show Variance between Individuals but High Test-Retest Reliability.

    Penny Moss

    Full Text Available Increased sensitivity to cold may be a predictor of persistent pain, but cold pain threshold is often viewed as unreliable. This study aimed to determine the within-subject reliability and between-subject variance of cold response, measured comprehensively as cold pain threshold plus pain intensity and sensation quality at threshold. A test-retest design was used over three sessions, one day apart. Response to cold was assessed at four sites (thenar eminence, volar forearm, tibialis anterior, plantar foot. Cold pain threshold was measured using a Medoc thermode and standard method of limits. Intensity of pain at threshold was rated using a 10cm visual analogue scale. Quality of sensation at threshold was quantified with indices calculated from subjects' selection of descriptors from a standard McGill Pain Questionnaire. Within-subject reliability for each measure was calculated with intra-class correlation coefficients and between-subject variance was evaluated as group coefficient of variation percentage (CV%. Gender and site comparisons were also made. Forty-five healthy adults participated: 20 male, 25 female; mean age 29 (range 18-56 years. All measures at all four test sites showed high within-subject reliability: cold pain thresholds r = 0.92-0.95; pain rating r = 0.93-0.97; McGill pain quality indices r = 0.87-0.85. In contrast, all measures showed wide between-subject variance (CV% between 51.4% and 92.5%. Upper limb sites were consistently more sensitive than lower limb sites, but equally reliable. Females showed elevated cold pain thresholds, although similar pain intensity and quality to males. Females were also more reliable and showed lower variance for all measures. Thus, although there was clear population variation, response to cold for healthy individuals was found to be highly reliable, whether measured as pain threshold, pain intensity or sensation quality. A comprehensive approach to cold response testing therefore may add

    It is observed that the working activity period has recently been decreasing in Poland; this applies to both the male and female populations. Since women constitute 48% of all workers employed in the national economy, this tendency may pose an important problem for the community and public health. The main information source for the absenteeism analysis are medical certificates which in Poland obligatorily document every instance of a sick-leave from work, irrespective of the length of sickness. A 15% random sample of all sickness certificates constitutes a database for the monitoring system of sickness absence. The lost time rate is the main parameter analysed by the system. In 1994 the rate of female sickness absence in Poland amounted to 25.1 days per one employee. In Poland the main causes of female sickness absence are: respiratory diseases--18% of all sickness absence (in the 16-19 age group--49%), and disorders of female genital tract and complications of pregnancy, childbirth and puerperium (17% of all sickness absence and 48% in the 20-29 age group). The most important chronic diseases that substantially contribute to the level of sickness absence include: musculoskeletal diseases (15%), diseases of the circulatory system (15%) and the nervous system and sense organs (11%). Over the period of 1990-1994 the highest rate of the female sickness absence related to gynecological diseases and pregnancy complications (mean annual increase--22%), and the musculoskeletal diseases (mean annual increase--10%).

    Full Text Available The study examines the core meaning of intrinsic shopping to understand their experimental aspects of recreational and leisure shopping. The study focus only on female shoppers of age group ranging from 25-30, and understand their mall experiences because this segment is newly transform into self dependent segment which have less social and familial liabilities and have enough enthusiasm to explore the world or their boundaries. The Grounded theory use for identification of recreational shopping themes which are (a seeking experiences and (b experimental shopping and each have respective sub themes. The themes are connected to the key idea that shoppers are motivated by their expectations and desires. The study uses social constructivism to find and understand the shopper meanings in real terms rather than imposing and judgment on them. The findings described the way people do recreational shopping and how shopping malls use as leisure space and become facilitators of recreational shopping activities. Females use malls to fulfill their recreational and leisure shopping experiences as this is the great way of enjoying shopping for females of small towns. In malls females not only enjoy product experiences but services experiences also which makes their shopping interesting. The way the female of this age category use malls help the marketers and retailers to understand this segment shopping patterns.

    Telomere dysfunction is a crucial event in malignant transformation and tumorigenesis. Telomere length in peripheral blood leukocytes has been associated with lung cancer risk, but the relationship has remained controversial. In this study, we investigated whether the association might be confounded by study of different histological subtypes of lung cancer. We measured relative telomere lengths in patients in a large case-control study of lung cancer and performed stratified analyses according to the two major histologic subtypes [adenocarcinoma and squamous cell carcinoma (SCC)]. Notably, patients with adenocarcinoma had longer telomeres than controls, whereas patients with SCC had shorter telomeres compared with controls. Long telomeres were associated with increased risk of adenocarcinoma, with the highest risk associated with female sex, younger age (telomeres were protective against SCC, particularly in male patients. Our results extend the concept that telomere length affects risk of lung cancer in a manner that differs with histologic subtype.

    The rennin–angiotensin–aldosterone system (RAAS) is a critical pathway in regulating blood pressure and salt/water homeostasis, possessing an intimate relationship with the development of systemic artery hypertension (SAH). Once hypertension is considered a risk factor for coronary artery disease (CAD), the RAAS is also related to this pathology. This investigation aimed to analyse if the frequencies of AGT M235T (rs699) and ACE I/D (rs4646994) polymorphisms are associated with CAD and SAH in African-Brazilians and Caucasian-Brazilians. In this study we analysed 714 subjects who underwent coronary angiography to detect obstructive lesions and CAD, as well as blood pressure measurement and SAH, grouped according to ethnicity: 266 African-Brazilians and 448 Caucasian-Brazilians. Among CAD and SAH cases and controls, the genotype and allele frequencies of ACE I/D polymorphism were similar in both ethnic groups. The AGT 235TT genotype and 235T allele frequencies were higher in SAH cases (32%, 54.7%) versus controls in Caucasian-Brazilians (19.8%, 46.4%; = 0.038, = 0.031, respectively). The AGT 235TT (OR = 1.8; = 0.028) demonstrated to be an independent factor risk in a multivariate logistic regression increasing SAH risk in Caucasians but not in African-Brazilians. In summary, AGT M235T polymorphism was associated with SAH risk in Caucasian-Brazilians, and no association was detected with CAD. No association was also observed in ACE I/D polymorphism either in CAD or SAH in African-Brazilians and Caucasian-Brazilians.

  7. Immune Aspects of Female Infertility

    Full Text Available Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility.

  8. Female Fitness in the Blogosphere

    Full Text Available This article analyzes self-portrayals and gender constructions among female personal trainers within an Internet-mediated framework of fitness culture. The empirical material comes from a close examination of three strategically selected blogs. The result shows that some of the blogs clearly build upon what Connell calls emphasized femininity, as a means of legitimizing and constructing appropriate female fitness. In addition, there are also tendencies of sexualization in text and imagery present. As such, these self-representations are framed within a cultural history of body fitness dominated by stereotypical ways of perceiving masculinity and femininity. However, this does not capture the entire presentation of the self among the analyzed fitness bloggers. The blogs also point in the direction of ongoing negotiations and subversions of traditional gender norms. Among other things, they show how irony and humor are used as a means of questioning normative gender constructions while empowering female fitness and bodyliness.

  9. The effect of parental education, prior achievement, self-efficacy, goal orientation, and effort on undergraduate science performance of Latinos and Caucasians

    Science.gov (United States)

    Stansbury, Sydney Lynn

    Compared with majority students, underrepresented minorities have demonstrated weaker undergraduate science performance. Previous research has attributed the weaker performance to socioeconomic factors that influence poorer precollege preparation. Studies also have found that, compared with majority students, underrepresented minorities are less confident about their science skills and more interested in extrinsic rewards of science careers. Social Cognitive Theory posits that low self-efficacy coupled with high extrinsic goal orientation diminishes cognitive engagement, resulting in weak performance. Applying motivational characteristics of underrepresented minority students to a Social Cognitive Model may explain why their performance is weaker than that of Caucasians. Thus, the purpose of this study was to investigate the degree to which motivation variables account for the difference between underrepresented minority and majority students' undergraduate science performance. The study was conducted at a large, predominantly Caucasian, private university located in an urban setting in the Southwest. Two hundred twenty-two students--154 Caucasians and 68 Latinos--enrolled in a general chemistry course participated. Students were administered the Motivation for Learning Questionnaire, designed specifically for this study, consisting of scales measuring the following variables: ethnicity, level of parental education, and effort exertion; self-efficacy, effort regulation, intrinsic goal orientation, and extrinsic goal orientation, measures from the Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991); and ability orientation, a measure from the Patterns of Adaptive Learning Survey (Midgley, Maehr, & Urdan, 1995). Financial aid information, chemistry and math placement test scores, and chemistry grades were obtained from other on-campus departments. Results demonstrated that the hypotheses were only partially confirmed by the

  10. Rural female adolescence: Indian scenario.

    1995-01-01

    This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values.

  11. General and specific responsiveness of the amygdala during explicit emotion recognition in females and males

    2009-08-01

    Full Text Available Abstract Background The ability to recognize emotions in facial expressions relies on an extensive neural network with the amygdala as the key node as has typically been demonstrated for the processing of fearful stimuli. A sufficient characterization of the factors influencing and modulating amygdala function, however, has not been reached now. Due to lacking or diverging results on its involvement in recognizing all or only certain negative emotions, the influence of gender or ethnicity is still under debate. This high-resolution fMRI study addresses some of the relevant parameters, such as emotional valence, gender and poser ethnicity on amygdala activation during facial emotion recognition in 50 Caucasian subjects. Stimuli were color photographs of emotional Caucasian and African American faces. Results Bilateral amygdala activation was obtained to all emotional expressions (anger, disgust, fear, happy, and sad and neutral faces across all subjects. However, only in males a significant correlation of amygdala activation and behavioral response to fearful stimuli was observed, indicating higher amygdala responses with better fear recognition, thus pointing to subtle gender differences. No significant influence of poser ethnicity on amygdala activation occurred, but analysis of recognition accuracy revealed a significant impact of poser ethnicity that was emotion-dependent. Conclusion Applying high-resolution fMRI while subjects were performing an explicit emotion recognition task revealed bilateral amygdala activation to all emotions presented and neutral expressions. This mechanism seems to operate similarly in healthy females and males and for both in-group and out-group ethnicities. Our results support the assumption that an intact amygdala response is fundamental in the processing of these salient stimuli due to its relevance detecting function.

    DRESS-syndrome (Drug Rash with Eosinophilia and Systemic Symptoms) is a severe drug-induced hypersensitivity syndrome characterized by diffuse maculopapular rash, lymphadenopathy, multivisceral involvement, eosinophilia and atypical lymphocytes with a mortality rate of 10-40% (Seminars in Cutaneous Medicine and Surgery, 1, 250). It is described in adults treated with aromatic antiepileptics and less frequently with sulphonamides, and non-steroidal anti-inflammatory drugs (Clinics in Dermatology, 23, 171; Pediatrics, 108, 485). We report on an 11-year-old Caucasian boy hospitalized with a skin eruption, lymphadenopathy, acute hepatitis, renal tubular involvement, haematological abnormalities and human-herpevirus-6 reactivation, treated with sulfasalazine and naproxen for juvenile idiopathic arthritis (JIA). This is the first report in children with rheumatic disease and highlights the possibility of sulfasalazine and naproxen-induced-DRESS-syndrome in children with JIA.

    Objective The objective of this study was to explore the decision-making processes and associated barriers and enablers that determine access and use of healthcare services in Arabic-speaking and English-speaking Caucasian patients with diabetes in Australia. Study setting and design Face-to-face semistructured individual interviews and group interviews were conducted at various healthcare settings—diabetes outpatient clinics in 2 tertiary referral hospitals, 6 primary care practices and 10 community centres in Melbourne, Australia. Participants A total of 100 participants with type 2 diabetes mellitus were recruited into 2 groups: 60 Arabic-speaking and 40 English-speaking Caucasian. Data collection Interviews were audio-taped, translated into English when necessary, transcribed and coded thematically. Sociodemographic and clinical information was gathered using a self-completed questionnaire and medical records. Principal findings Only Arabic-speaking migrants intentionally delayed access to healthcare services when obvious signs of diabetes were experienced, missing opportunities to detect diabetes at an early stage. Four major barriers and enablers to healthcare access and use were identified: influence of significant other(s), unique sociocultural and religious beliefs, experiences with healthcare providers and lack of knowledge about healthcare services. Compared with Arabic-speaking migrants, English-speaking participants had no reluctance to access and use medical services when signs of ill-health appeared; their treatment-seeking behaviours were straightforward. Conclusions Arabic-speaking migrants appear to intentionally delay access to medical services even when symptomatic. Four barriers to health services access have been identified. Tailored interventions must be developed for Arabic-speaking migrants to improve access to available health services, facilitate timely diagnosis of diabetes and ultimately to improve glycaemic control.

    Full Text Available Abstract Background Recent studies in children have demonstrated that frequent occurrence of parasomnias is related to increased sleep disruption, mental disorders, physical harm, sleep disordered breathing, and parental duress. Although there have been several cross-sectional and clinical studies of parasomnias in children, there have been no large, population-based studies using full polysomnography to examine the association between parasomnias and sleep disordered breathing. The Tucson Children's Assessment of Sleep Apnea study is a community-based cohort study designed to investigate the prevalence and correlates of objectively measured sleep disordered breathing (SDB in pre-adolescent children six to 11 years of age. This paper characterizes the relationships between parasomnias and SDB with its associated symptoms in these children. Methods Parents completed questionnaires pertaining to their child's sleep habits. Children had various physiological measurements completed and then were connected to the Compumedics PS-2 sleep recording system for full, unattended polysomnography in the home. A total of 480 unattended home polysomnograms were completed on a sample that was 50% female, 42.3% Hispanic, and 52.9% between the ages of six and eight years. Results Children with a Respiratory Disturbance Index of one or greater were more likely to have sleep walking (7.0% versus 2.5%, p p p Conclusions In this population-based cohort study, pre-adolescent school-aged children with SDB experienced more parasomnias than those without SDB. Parasomnias were associated with a higher prevalence of other sleep disturbances and learning problems. Clinical evaluation of children with parasomnias should include consideration of SDB.

  2. Does the treatment of type 2 diabetes mellitus with the DPP-4 inhibitor vildagliptin reduce HbA1c to a greater extent in Japanese patients than in Caucasian patients?

    Background Previous work suggests that Japanese patients with type 2 diabetes mellitus (T2DM) may respond more favorably to a DPP-4 (dipeptidyl peptidase-4) inhibitor than Caucasians. We aimed to compare the efficacy of the DPP-4 inhibitor vildagliptin (50 mg twice daily [bid]) between Japanese and Caucasian populations. Methods This analysis pooled data from 19 studies of drug-naïve patients with T2DM who were treated for 12 weeks with vildagliptin 50 mg bid as monotherapy. The pool comprised Japanese patients (n=338) who had been treated in Japan and Caucasian patients (n=1,275) who were treated elsewhere. Change from baseline (Δ) in glycated hemoglobin (HbA1c) at 12 weeks (in millimoles per mole) versus baseline HbA1c (both in percentage National Glycohemoglobin Standardization Program units [NGSP%] and millimoles per mole) for each population was reported. Universal HbA1c in millimoles per mole was calculated from either the Japanese Diabetes Society or the NGSP% HbA1c standards. Results At baseline, mean values for Japanese and Caucasian patients, respectively, were as follows: age, 59 years and 56 years; % male, 69% and 57%. The average HbA1c was reduced from 7.90% to 6.96% (Japanese Diabetes Society) and from 8.57% to 7.50% (United States National Glycohemoglobin Standardization Program), while HbA1c was reduced from 63 mmol/mol to 53 mmol/mol and from 70 mmol/mol to 58 mmol/mol in Japanese and Caucasians, respectively. ΔHbA1c increased with increasing baseline in both populations. The slopes were the same (0.41, r2=0.36; and 0.41, r2=0.15), and the intercepts were 15.4 mmol/mol and 17.2 mmol/mol, respectively. In Japanese patients, mean ΔHbA1c was greater by 1.7 mmol/mol (0.2% NGSP HbA1c) at any given baseline HbA1c than in Caucasians (P=0.01). Conclusion The present pooled analysis suggests that Japanese patients respond better to vildagliptin treatment compared with Caucasians. However, when glycemic control was corrected by using the same glycemic

    Full Text Available Female Genital Mutilation is widely practiced in Egypt as well as in big sections of the African continent. The tradition of mutilation of the female genital areas has been practiced over the course of many years in the country and has been attributed to being promoted by the Islamic religion in Egypt. The Islamic religion is the most widely practiced religion within Egypt and therefore is linked to being the main reason why the country possesses one of the highest prevalence rates of the practice within Africa, according to many surveys performed by many leading agencies and nongovernmental organizations that advocate for the abolition of the practice within the country. FGM as a social health concern has been realized as not possessing any health benefits for the women and young girls who are taken through the practice.

    The intent of the study was to obtain data on the incidence of female sexual fantasy and on the relationship of background, personality, and attitudinal factors to the quantity of sexual fantasies. The participants were 102 university women students between the ages of 19 and 45 yr. An original Female Sexual Fantasy Questionnaire, a short form of the Attitude Toward Women Scale, the 16 PF, and the background variables of age, sexual experience, marital status, and religion provided data for the analysis. Conclusions were that 99% of the women engaged in sexual fantasy at least occasionally and that age, sexual experience, anxiety, independence, and liberal attitudes toward women are all related to frequency of sexual fantasy.

    Full Text Available Lauren L Levy, Jason J Emer Department of Dermatology, Mount Sinai School of Medicine, New York, NY, USA Abstract: Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification and women exhibiting diffuse hair thinning over the crown (increased part width and sparing of the frontal hairline (Ludwig classification. Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride, prostaglandin analogs (eg, bimatoprost, latanoprost, and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss.

    2011-01-01

    Full Text Available Melanoma is a malignant tumor that can affect any area of the anatomical economy. Its appearance in the female urethra is extremely rare, with approximately 121 cases in indexed literature since 1966. The subject to be described is an 86-year-old woman who seeks assessment for intermittent macroscopic hematuria with blood clots of 3 months progression. On physical examination, there are no suspicious lesions detected on the surface of the skin. On external genital examination, it is observed a friable lesion at the level of the urethral meatus, with heterogeneous digitations, dark brown to black, and irregular polycyclic borders. No inguinal adenomegalies were palpated. Cystourethroscopy and biopsy of the lesion confirm the diagnosis. Melanoma of the female urethra is an extremely infrequent pathology. Due to lack of published case reports and the absence of prospective randomized trials on treatment outcomes, treatment must be directed using the same anatomical and surgical criteria for female urethral tumors, adding also the concepts of treatment of mucosal melanoma, even though its prognosis is different from the before mentioned.

    CHRNA5-A3-B4 variants, rs16969968, rs588765 and rs578776, are consistently associated with tobacco consumption among smokers, but the association with smoking cessation is less consistent. Among the studies that reported significant associations with cessation, the effects were observed in smokers treated with placebo treatment in some studies and conversely in those receiving active pharmacological therapy (bupropion and nicotine replacement therapies) in others. Thus, it remains unclear whether CHRNA5-A3-B4 is a useful marker for optimizing smoking cessation. Using data from 654 Caucasian smokers treated with placebo, nicotine patch or varenicline, we investigated whether CHRNA5-A3-B4 variants were associated with smoking cessation outcomes, and whether there were significant genotype-by-treatment or haplotype-by-treatment interactions. We observed no significant associations between CHRNA5-A3-B4 variants and smoking cessation, despite replicating previous associations with baseline tobacco consumption. At end of treatment the effect size on smoking cessation in the placebo, patch and varenicline groups for rs16969968 [GG vs. GA+AA] was OR = 0.66 (P = 0.23), OR = 1.01 (P = 0.99), and OR = 1.30 (P = 0.36) respectively, of rs588765 [CC vs. CT+TT] was OR = 0.96 (P = 0.90), OR = 0.84 (P = 0.58), and OR = 0.74 (P = 0.29) respectively, and for rs578776 [GG vs. GA+AA] on smoking cessation was OR = 1.02 (P = 0.95), OR = 0.75 (P = 0.35), and OR = 1.20 (P = 0.51) respectively. Furthermore, we observed no associations with cessation using the CHRNA5-A3-B4 haplotype (constructed using rs16969968 and rs588765), nor did we observe any significant genotype-by-treatment interactions, with or without adjusting for the rate of nicotine metabolism (all P>0.05). We also observed no significant genetic associations with 6 month or 12 month smoking abstinence. In conclusion, we found no association between CHRNA5-A3-B4 variants and smoking cessation rates in this clinical trial

    Full Text Available Age-related changes in organ and tissue masses may add to changes in the relationship between resting energy expenditure (REE and fat free mass (FFM in normal and overweight healthy Caucasians. Secondary analysis using cross-sectional data of 714 healthy normal and overweight Caucasian subjects (age 18–83 years with comprehensive information on FFM, organ and tissue masses (as assessed by magnetic resonance imaging (MRI, body density (as assessed by Air Displacement Plethysmography (ADP and hydration (as assessed by deuterium dilution (D2O and REE (as assessed by indirect calorimetry. High metabolic rate organs (HMR summarized brain, heart, liver and kidney masses. Ratios of HMR organs and muscle mass (MM in relation to FFM were considered. REE was calculated (REEc using organ and tissue masses times their specific metabolic rates. REE, FFM, specific metabolic rates, the REE-FFM relationship, HOMA, CRP, and thyroid hormone levels change with age. The age-related decrease in FFM explained 59.7% of decreases in REE. Mean residuals of the REE-FFM association were positive in young adults but became negative in older subjects. When compared to young adults, proportions of MM to FFM decreased with age, whereas contributions of liver and heart did not differ between age groups. HOMA, TSH and inflammation (plasma CRP-levels explained 4.2%, 2.0% and 1.4% of the variance in the REE-FFM residuals, but age and plasma T3-levels had no effects. HMR to FFM and MM to FFM ratios together added 11.8% on to the variance of REE-FFM residuals. Differences between REE and REEc increased with age, suggesting age-related changes in specific metabolic rates of organs and tissues. This bias was partly explained by plasmaT3-levels. Age-related changes in REE are explained by (i decreases in fat free mass; (ii a decrease in the contributions of organ and muscle masses to FFM; and (iii decreases in specific organ and tissue metabolic rates.

    Full Text Available OBJECTIVE: To estimate the prevalence of female sexual dysfunction symptoms and the associated risk factors in a sample of patients with substance-related disorders admitted to a specialized in-patient care unit. METHODS: This study used a cross-section design, with eight months of data collection, conducted with substance-dependent women using structured questionnaires to collect socio-demographic data and identify their drug of choice. The Drug Abuse Screening Test, Short Alcohol Dependence Data questionnaire, Fagerstrom Test for Nicotine Dependence, and Arizona Sexual Experience Scale were also administered. RESULTS: The sample consisted of 105 women who had a mean age of 34.8 years (SD = 12.1, range = 18-65 and were predominantly heterosexual (74.3%, single (47.6%, Caucasian (50.5%, catholic (36.2%, and educated only to the level of primary education (40%, with a monthly family income of up to one minimum salary (37.5%. In 42.9% of the patients, crack was the drug of choice; 47.6% of the sample qualified for the Drug Abuse Screening Test (substantial problems related to drugs, 43.8% exhibited Short Alcohol Dependence Data (moderate or severe dependency, 47.6% exhibited Fagerstrom Test for Nicotine Dependence (high or very high nicotine dependence. The prevalence of sexual dysfunction symptoms was 34.2% (95% CI = [25.3, 44.1], and a high level of nicotine dependence and low income increased the chances of having sexual dysfunction by 2.72-fold and 2.54 fold, respectively. An association was also observed between female sexual dysfunction symptoms and schooling and levels of drug dependence. CONCLUSIONS: Female sexual dysfunction symptoms were common among this sample and primarily associated with high levels of nicotine use.

    The timing of puberty is controlled by many genes. The elements coordinating this process have not, however, been identified. Here we show that an epigenetic mechanism of transcriptional repression times the initiation of female puberty in rats. We identify silencers of the Polycomb group (PcG) as major contributors to this mechanism, and show that PcG proteins repress Kiss1, a puberty-activating gene. Hypothalamic expression of two key PcG genes, Eed and Cbx7, decreases and methylation of their promoters increases preceding puberty. Inhibiting DNA methylation blocks both events and results in pubertal failure. The pubertal increase in Kiss1 is accompanied by EED loss from the Kiss1 promoter and enrichment of histone H3 modifications associated with gene activation. Preventing the eviction of EED from the Kiss1 promoter disrupts pulsatile GnRH release, delays puberty, and compromises fecundity. Our results identify epigenetic silencing as a novel mechanism underlying the neuroendocrine control of female puberty. PMID:23354331

In this context, programs to encourage and promote the entrepreneurial spirit in women considering that, on a global level, one third of new businesses are their creation, a significant part of SMEs, the primary source of new workplaces and of economic growth in a local community. In a competition where women continue to be confronted with more obstacles than men, measures must be taken to ensure the best possible context to support female entrepreneurship in such a way that local communities to fully benefit from their potential in creating workplaces, economic and social development on a local, national and European scale. The lack of confidence in creating their own businesses, difficulty in balancing professional and family life, inability to obtain the capital necessary for developing their business, difficulty in preparation and limited access to information are all problems that hinder initiative and the development of women's entrepreneurship. Female entrepreneurs are in need of recognition, from financers and business partners, logistical support and help in increasing managerial and leading capacity.

    Full Text Available The current study addressed whether rated femininity, attractiveness, and health in female faces are associated with numerous indices of self-reported health history (number of colds/stomach bugs/frequency of antibiotic use in a sample of 105 females. It was predicted that all three rating variables would correlate negatively with bouts of illness (with the exception of rates of stomach infections, on the assumption that aspects of facial appearance signal mate quality. The results showed partial support for this prediction, in that there was a general trend for both facial femininity and attractiveness to correlate negatively with the reported number of colds in the preceding twelve months and with the frequency of antibiotic use in the last three years and the last twelve months. Rated facial femininity (as documented in September was also associated with days of flu experienced in the period spanning the November-December months. However, rated health did not correlate with any of the health indices (albeit one marginal result with antibiotic use in the last twelve months. The results lend support to previous findings linking facial femininity to health and suggest that facial femininity may be linked to some aspects of disease resistance but not others.

  1. Identification of PLCL1 gene for hip bone size variation in females in a genome-wide association study.

    Directory of Open Access Journals (Sweden)

    Yao-Zhong Liu

    Full Text Available Osteoporosis, the most prevalent metabolic bone disease among older people, increases risk for low trauma hip fractures (HF that are associated with high morbidity and mortality. Hip bone size (BS has been identified as one of the key measurable risk factors for HF. Although hip BS is highly genetically determined, genetic factors underlying the trait are still poorly defined. Here, we performed the first genome-wide association study (GWAS of hip BS interrogating approximately 380,000 SNPs on the Affymetrix platform in 1,000 homogeneous unrelated Caucasian subjects, including 501 females and 499 males. We identified a gene, PLCL1 (phospholipase c-like 1, that had four SNPs associated with hip BS at, or approaching, a genome-wide significance level in our female subjects; the most significant SNP, rs7595412, achieved a p value of 3.72x10(-7. The gene's importance to hip BS was replicated using the Illumina genotyping platform in an independent UK cohort containing 1,216 Caucasian females. Two SNPs of the PLCL1 gene, rs892515 and rs9789480, surrounded by the four SNPs identified in our GWAS, achieved p values of 8.62x10(-3 and 2.44x10(-3, respectively, for association with hip BS. Imputation analyses on our GWAS and the UK samples further confirmed the replication signals; eight SNPs of the gene achieved combined imputed p values<10(-5 in the two samples. The PLCL1 gene's relevance to HF was also observed in a Chinese sample containing 403 females, including 266 with HF and 177 control subjects. A SNP of the PLCL1 gene, rs3771362 that is only approximately 0.6 kb apart from the most significant SNP detected in our GWAS (rs7595412, achieved a p value of 7.66x10(-3 (odds ratio = 0.26 for association with HF. Additional biological support for the role of PLCL1 in BS comes from previous demonstrations that the PLCL1 protein inhibits IP3 (inositol 1,4,5-trisphosphate-mediated calcium signaling, an important pathway regulating mechanical sensing of

  2. Low Maternal Vitamin B12 Status Is Associated with Lower Cord Blood HDL Cholesterol in White Caucasians Living in the UK

    2015-04-01

    Full Text Available Background and Aims: Studies in South Asian population show that low maternal vitamin B12 associates with insulin resistance and small for gestational age in the offspring. Low vitamin B12 status is attributed to vegetarianism in these populations. It is not known whether low B12 status is associated with metabolic risk of the offspring in whites, where the childhood metabolic disorders are increasing rapidly. Here, we studied whether maternal B12 levels associate with metabolic risk of the offspring at birth. Methods: This is a cross-sectional study of 91 mother-infant pairs (n = 182, of white Caucasian origin living in the UK. Blood samples were collected from white pregnant women at delivery and their newborns (cord blood. Serum vitamin B12, folate, homocysteine as well as the relevant metabolic risk factors were measured. Results: The prevalence of low serum vitamin B12 (<191 ng/L and folate (<4.6 μg/L were 40% and 11%, respectively. Maternal B12 was inversely associated with offspring’s Homeostasis Model Assessment 2-Insulin Resistance (HOMA-IR, triglycerides, homocysteine and positively with HDL-cholesterol after adjusting for age and BMI. In regression analysis, after adjusting for likely confounders, maternal B12 is independently associated with neonatal HDL-cholesterol and homocysteine but not triglycerides or HOMA-IR. Conclusions: Our study shows that low B12 status is common in white women and is independently associated with adverse cord blood cholesterol.

    New fine-resolution surface elevation data was implemented into HARMONIE-AROME-SURFEX Numerical Weather Prediction (NWP) system. The grid-scale mean orography, used as a basis of the model's terrain-following vertical coordinate, as well as variables for suggested new parametrizations of radiation and momentum fluxes were derived. Validation against the surface observations from the Sochi Winter Olympic Games 2014, provided by the WMO FROST-2014 program at the Caucasian mountains, showed minor degradation of the of then screen-level temperature forecast when only the source orography was updated. Implementation of the orographic radiation parametrizations allowed to alleviate the degradation of scores. Detailed sensitivity studies, done by using three-dimensional and single-column experiments, showed that substantial and physically realistic changes in the downwelling short- and longwave radiation fluxes took place locally. However, their influence on the the simulated screen-level temperature remained small. Comparison of the simulated and observed radiation fluxes would offer a reliable alternative for validation of NWP models. Unfortunately, surface-level radiation observations were not made during the Sochi Olympics.

    2006-01-01

    Background: specific polymorphisms of genes regulating intracellular redox balance and oxidative stress are related to atherogenesis. Some studies have identified a relationship between progression of atherosclerosis and C242T mutation in CYBA gene coding for p22phox, a subunit of the NADH/NADPH oxidase system. Design: we investigated whether the C242T nucleotide transition is associated with the presence of coronary artery disease (CAD) in a population of 494 Caucasian Italians undergoing coronary angiography to diagnose the cause of chest pain. Results: the frequency of the T mutant allele that we found in 276 patients with angiographically documented CAD was significantly higher compared to what we observed in 218 subjects with normal coronary arteries (Controls) (respectively: 0.400 and 0.332, p < 0.01). The prevalence of the T allele was even stronger when we compared: 1) early onset (age ≤55) vs late onset (age ≥65) single-vessel CAD patients (respectively: 0.75 and 0.48, p < 0.05), and 2) the subgroup of CAD patients with at least one ≥98% stenosis in a coronary vessel vs those with no ≥98% stenosis in a coronary vessel (respectively: 0.425 and 0.365, p < 0.05). Conclusions: these results support the increased risk of developing early CAD and of having rapid progression of coronary stenosis in subjects carrying the C242T nucleotide transition among the Italian population.

    The French population is the result of mixing of different peoples including the Celts, Saxons, Germans, Italians and Hispanics. Between 1981 and 1993 patients were selected during investigations in France for haematological disorders associated or otherwise with the presence of a haemoglobin (Hb) variant. Further carriers of abnormal Hb were identified by HPLC measurement of glycated Hb in diabetics and by neonatal screening. Four-hundred and thirty-two subjects were found to be heterozygous for one of the 119 different alpha and the beta gene alleles encountered. These variants were characterised by a combination of 6 electrophoretic methods and in some cases by protein structure determinations. Some mutants reflected the population movements in and into France. A few mutants are frequently described in the French Caucasian population: Hb Lepore Boston, Hb D Punjab, whereas others appear to be anthropological markers. Hb Winnipeg has only been found in the West of France (Normandy); Hb J Baltimore is mainly found in French subjects of Spanish origin. Several cases of sporadic and previously undescribed mutations of Hb were identified. The last immigration waves from Africa and Asia appear to have contributed to the evolution of the pattern of haemoglobinopathies in the French population (Hb S, Hb O Arab or Hb C).

    Full Text Available Abstract Introduction The existence of a graft-versus-lymphoma effect is well established. When lacking a firm diagnosis, however, the clinician is challenged to to weigh the potential benefits of the graft-versus-lymphoma effect against potential dangers of graft-versus-host disease as well as against generalized (viral infections. Case presentation We present evidence for a graft-versus-lymphoma effect in a 64-year-old caucasian woman with a transplanted peripheral blood-stem-cell graft from her Human Leukocyte Antigen-identical sister, and propose diagnostic measures to distinguish between graft-versus-host effect, and against viral disease or drug-induced reactions. Conclusion We were able to identify an allogeneic graft-reaction against progressive lymphoma alongside an erythema consistent with acute graft-versus-host disease of the skin. Establishing a firm diagnosis enabled us to decide against T-cell suppression (such as by using cyclosporine. Anti-lymphoma activity was favoured, by means of the allogeneic graft, local radiation and immunotherapy. This illustrates the importance of a sound differential diagnosis of erythema after allogeneic stem-cell transplantation, including assessment of viral disease of the affected tissue.

  8. Female condom launched in UK.

    1992-01-01

    The lone-awaited female condom, Femidom, is to be launched at the end of September by manufacturers Chartex. It is being welcomed by the FPA [Family Planning Association] and other family planning experts as a valuable addition to the existing range of contraceptive methods and as an alternative to the male condom in offering effective protection against sexually transmitted diseases including HIV. A lubricated, loose-fitting polyurethane sheath, Femidom is inserted into the vagina at any time before sex. An inner ring holds the condom in place beyond the pubic bone and an outer ring lies flat against the vulva. In addition to extending choice, it is under direct control of the woman. As FPA Director Doreen Massey puts it: "We have to face the fact that some women who want safer sex can't get their partners to use condoms. for the 1st time with Femidom, you can insist that if he won't use a condom, you'll use yours." In trails of self-selected couples, up to 2/3 of women and their partners found the product acceptable. a study at the Institute of Population Studies in Exeter showed that while some couples had initial misgivings about the condom's size and appearance, especially its visibility when in position, these often declined with repeated use. Researcher Dr. Nicholas Ford pointed out that if the female condom makes a woman feel unattractive, her partner's comments may well influence these feelings. Users' experience of insertion and the condom's comfort also improved with repeated use. While there are no large studies showing ranges of effectiveness, it is likely to be as effective as the male condom (about 85%-98%). In a study of 106 women at the margaret Pyke Center in London, there were 7 unplanned pregnancies: 4 were due to inconsistent use of the method and 3 were method failures. Breakages were rare. 1/3 of participants dropped out in the 1st month. Users should continue with their existing contraceptive method until they are sure that they are using

    This paper presents the results of an anthropometric survey conducted on Korean female workers in the garment industry. The data was collected as part of a project to modify work stations that utilized equipment from other countries. A set of 23 body dimensions were taken from a sample of 101 workers (aged 18-28 years). The anthropometric measurements are presented and compared with those of the Western and Japanese female. The results indicate that the body dimensions of the Korean female are different from those of both the Western and the Japanese female. The ratio of sitting height to standing height for the Korean female is closer to that of the Western female than it is the Japanese female.

    Hypoactive sexual desire disorder (HSDD) is the most commonly described form of female sexual dysfunction. There is currently no pharmacological therapy approved to treat HSDD, and therefore, there is an unmet medical need for the development of efficacious treatment alternatives. Flibanserin is a novel, non-hormonal drug for the treatment of HSDD in pre- and postmenopausal women, although the application submitted to the U.S. Food and Drug Administration by Sprout Pharmaceuticals is only for premenopausal women. Flibanserin works by correcting an imbalance of the levels of the neurotransmitters that affect sexual desire. More specifically, flibanserin increases dopamine and norepinephrine, both responsible for sexual excitement, and decreases serotonin, responsible for sexual inhibition. Clinically, flibanserin has exhibited some encouraging results in terms of its ability to increase the frequency of satisfying sexual events, and the intensity of sexual desire. However, adverse events such as dizziness, nausea, fatigue and somnolence, typical of a centrally acting drug, are also frequently related to flibanserin treatment.

  12. The battle against female circumcision.

    Most of Nigeria's estimated 50 million females have suffered female genital mutilation (FGM). Those who have escaped FGM either belong to nonmutilating tribes, are members of enlightened families, or have been overlooked for some reason. Nigerian girls who undergo FGM are told that the pain the suffer will be eased when they marry, but they are not told that this will likely occur because sexual intercourse will widen their vaginal opening or else it will be surgically widened. Many who submit their children to this mutilation have no clear idea about why it is called for except to claim that it protects a family's honor by proving virginity. A Yoruba scholar claims that FGM is used in that tribe to reduce a woman's sexual desires so that she will not engage in intercourse during the 18 months she breast feeds her baby (it is believed that sperm migrates to the mother's milk and can make the baby ill). Yoruba husbands have no curb on their sexual pleasure and may marry as many wives as they can afford. Yorubas mutilate girls when they are 2-8 years old. Ibos, on the other hand, mutilate young women when they are preparing for marriage as part of an initiation ceremony. Abohs mutilate women during their first pregnancy in the belief that this aids the safe delivery of the child by protecting it from contact with the "lethal" clitoris during delivery. While some argue for maintaining FGM because it is an African tradition, other harmful customs, such as facial scarification, have been eliminated.

    This qualitative study investigated the life experiences of five academically gifted female students in math and science in reflection of their elementary learning prior to enrollment at a prestigious science and mathematics high school. The elite high school limits admission to the state of Illinois' top students. The purpose of this study is to unfold the story of five academically gifted females in attendance at the elite high school reflecting on their life experiences in elementary school that contributed to their current academic success. Twelve female students, who at the time of this study were currently in their senior year (12th grade) of high school, were solicited from the top academic groups who are regarded by their teachers as highly successful in class. Students were selected as part of the study based on academic status, survey completion and interest in study, Caucasian and Asian ethnicity, locale of elementary school with preference given to the variety of school demographics---urban, suburban, and rural---further defined the group to the core group of five. All female participants were personally interviewed and communicated via Internet with the researcher. Parents and teachers completing surveys as well met the methodological requirements of triangulation. An emergent theme of paternal influence came from the research. Implications supported in the research drawn from this study to increase achievement of academically gifted females include: (a) proper early identification of learner strengths plays a role; (b) learning with appropriate intellectual peers is more important than learning with their age group; (c) teachers are the greatest force for excellent instruction; (d) effective teaching strategies include cooperative learning, multi-sensory learning, problem-based learning, and hands-on science; (e) rigor in math is important; (f) gender and stereotypes need not be barriers; (g) outside interests and activities are important for self

    Full Text Available This study attempts to analyze the letters of officer/orientalist and military oriental scholar, officer in the Intelligence Section of the Staff of the Caucasian Military District, Staff Captain Konstantin Nikolayevich Smirnov, sent by him from the Turkish and Iranian sectors of the Caucasian front to his wife Kseniya Karlovna Smirnova (Kester over the period 1914–1917. Depending on changes in the deployment of Russian troops fighting against the Turkish army, as well as the German-Turkish block, both in the north-eastern part of Turkey and in the north-west of Iran, K.N. Smirnov had sent those letters from Kamarli, Diadin, Iğdır, Beyazıt, Trebizond, Kazvin, Kermanshah, Kerind, Qasr-e Shirin, Ava now to Tiflis and now to Sevastopol, Hamadan, and Kazvin, where his wife was staying at that particular point in time. K.N. Smirnov’s surviving letters, just like their fragments, give us an idea of the military/political situation along the line of contact with the enemy on the Caucasian front, as well as many aspects of the activity of officers from the Expeditionary Corps of General N.N. Baratov in Iran over the period 1915–1917. Of interest is his characterization of the personal qualities of many Russian officers, such as General N.N. Baratov, the immediate superior of Staff Captain Smirnov, who at the time headed the reconnaissance unit of the Expeditionary Corps, Colonel N.F. Ern, Chief of Staff, and other officers of the corps. The letters also bring to light the character of activity by K.N. Smirnov as a ―political officer‖. K.N. Smirnov’s letters contain extremely rare information on the episode of short-term Anglo-Russian military cooperation on the Caucasian front intended to coordinate actions against Turkish troops in Mesopotamia.

    Full Text Available Brain imaging studies have consistently shown subgenual Anterior Cingulate Cortical (sgACC involvement in emotion processing. COMT Val158 and Met158 polymorphisms may influence such emotional brain processes in specific ways. Given that resting-state fMRI (rsfMRI may increase our understanding on brain functioning, we integrated genetic and rsfMRI data and focused on sgACC functional connections. No studies have yet investigated the influence of the COMT Val158Met polymorphism (rs4680 on sgACC resting-state functional connectivity (rsFC in healthy individuals. A homogeneous group of sixty-one Caucasian right-handed healthy female university students, all within the same age range, underwent rsfMRI. Compared to Met158 homozygotes, Val158 allele carriers displayed significantly stronger rsFC between the sgACC and the left parahippocampal gyrus, ventromedial parts of the inferior frontal gyrus, and the nucleus accumbens (NAc. On the other hand, compared to Val158 homozygotes, we found in Met158 allele carriers stronger sgACC rsFC with the medial frontal gyrus, more in particular the anterior parts of the medial orbitofrontal cortex. Although we did not use emotional or cognitive tasks, our sgACC rsFC results point to possible distinct differences in emotional and cognitive processes between Val158 and Met158 allele carriers. However, the exact nature of these directions remains to be determined.

    Full Text Available We report a case of a 52-year-old immunocompetent Caucasian female treated for necrotizing Streptococcus intermedius pneumonia and review available literature of similar cases. Our patient presented with respiratory failure and required hospitalization and treatment in the intensive care unit. Moreover, she required surgical drainage of right lung empyema as well as decortication and resection. The review of literature revealed three cases of S. intermedius pneumonia, one of which was a mortality. Comparison of the published cases showed a highly varied prehospital course and radiological presentations, with a symptomatic phase ranging from 10 days to five months. Radiological findings varied from an isolated pleural effusion to systemic disease with the presence of brain abscesses. Immunocompetence appears to correlate well with the overall prognosis. In addition, smoking appears to be an important risk factor for S. intermedius pneumonia. In 2 (50% of cases, pleural fluid analysis identified S. intermedius. In contrast, no organism was found in our patient, necessitating the acquisition of lung tissue sample for the diagnosis. In conclusion, both medical and surgical management are necessary for effective treatment of S. intermedius pneumonia. The outcome of treatment is good in immunocompetent individuals.

    Polycyclic aromatic hydrocarbons (PAH) are widespread pollutants commonly found in air, food, and drinking water. Benzo[a]pyrene is a well-studied representative PAH found in air from fossil fuel combustion and a transplacental carcinogen experimentally. PAHs bind covalently to DNA to form DNA adducts, an indicator of DNA damage, and an informative biomarker of potential cancer risk. Associations between PAH-DNA adduct levels and both cancer risk and developmental deficits have been seen in previous experimental and epidemiologic studies. Several genes have been shown to play an important role in the metabolic activation or detoxification of PAHs, including the cytochrome P450 genes CYP1A1 and CYP1B1 and the glutathione S-transferase (GST) genes GSTM1, and GSTT2. Genetic variation in these genes could influence susceptibility to adverse effects of PAHs in polluted air. Here, we have explored interactions between prenatal PAH exposure and 17 polymorphisms in these genes (rs2198843, rs1456432, rs4646903, rs4646421, rs2606345, rs7495708, rs2472299, rs162549, rs1056837, rs1056836, rs162560, rs10012, rs2617266, rs2719, rs1622002, rs140194, and gene deletion GSTM1-02) and haplotypes on PAH-DNA adducts in cord blood of 547 newborns and in maternal blood of 806 mothers from three different self-described ethnic groups: African Americans, Dominicans, and Caucasians. PAHs were measured by personal air monitoring of mothers during pregnancy. Significant interactions (p < 0.05) were observed between certain genetic polymorphisms and CYP1A1 haplotype and PAHs in mothers and their newborns in the three ethnic groups. However, with our limited sample size, the current findings are suggestive only, warranting further study.

    Full Text Available It has been postulated that the persistent short intravaginal ejaculation latency time (IELT of men with lifelong premature ejaculation (LPE is related to 5-hydroxytryptamine (HT2C receptor functioning. The aim of this study was to investigate the relationship of Cys23Ser 5-HT2C receptor gene polymorphism and the duration of IELT in men with LPE. Therefore, a prospective study was conducted in 64 Dutch Caucasian men with LPE. Baseline IELT during coitus was assessed by stopwatch over a 1-month period. All men were genotyped for Cys23Ser 5-HT2C receptor gene polymorphism. Allele frequencies and genotypes of Cys and Ser variants of 5-HT2C receptor gene polymorphism were determined. Association between Cys/Cys and Ser/Ser genotypes and the natural logarithm of the IELT in men with LPE were investigated. As a result, the geometric mean, median and natural mean IELT were 25.2, 27.0, 33.9 s, respectively. Of all men, 20.0%, 10.8%, 23.1% and 41.5% ejaculated within 10, 10-20, 20-30 and 30-60 s after vaginal penetration. Of the 64 men, the Cys/Cys and Ser/Ser genotype frequency for the Cys23Ser polymorphism of the 5-HT2C receptor gene was 81% and 19%, respectively. The geometric mean IELT of the wildtypes (Cys/Cys is significantly lower (22.6 s; 95% CI 18.3-27.8 s than in male homozygous mutants (Ser/Ser (40.4 s; 95% CI 20.3-80.4 s (P = 0.03. It is concluded that Cys23Ser 5-HT2C receptor gene polymorphism is associated with the IELT in men with LPE. Men with Cys/Cys genotype have shorter IELTs than men with Ser/Ser genotypes.

    {sup 18}F-Florbetaben is a positron emission tomography (PET) tracer indicated for imaging cerebral beta-amyloid deposition in adult patients with cognitive impairment who are being evaluated for Alzheimer's disease and other causes of cognitive decline. The present study examined ethnic comparability of the plasma pharmacokinetics, which is the input to the brain, between Caucasian and Japanese subjects. Two identical phase I trials were performed in 18 German and 18 Japanese healthy volunteers to evaluate the plasma pharmacokinetics of a single dose of 300 MBq {sup 18}F-florbetaben, either of low (≤5 μg, LD) or high (50-55 μg, HD) mass dose. Pharmacokinetic parameters were evaluated based on the total {sup 18}F radioactivity measurements in plasma followed by metabolite analysis using radio-HPLC. The pharmacokinetics of {sup 18}F-florbetaben was characterized by a rapid elimination from plasma. The dose-normalized areas under the curve of {sup 18}F-florbetaben in plasma as an indicator of the input to the brain were comparable between Germans (LD: 0.38 min/l, HD: 0.55 min/l) and Japanese (LD: 0.35 min/l, HD: 0.45 min/l) suggesting ethnic similarity, and the mass dose effect was minimal. A polar metabolite fraction was the main radiolabelled degradation product in plasma and was also similar between the doses and the ethnic groups. Absence of a difference in the pharmacokinetics of {sup 18}F-florbetaben in Germans and Japanese has warranted further global development of the PET imaging agent. (orig.)

    Tobacco smoking is inconsistently associated with breast cancer. Although some studies suggest that breast cancer risk is related to passive smoking, little is known about the association with breast cancer by tumor hormone receptor status. We aimed to explore the association between lifetime passive smoking and risk of breast cancer subtypes defined by estrogen receptor and progesterone receptor status among non-smoking Caucasian women. A hospital-based case-control study was performed in 585 cases and 1170 controls aged 28–90 years. Information on lifetime passive smoking and other factors was collected via a self-administered questionnaire. Logistic regression was used for analyses restricted to the 449 cases and 930 controls who had never smoked actively. All statistical tests were two-sided. Adjusted odds ratio of breast cancer was 1.01 (95% confidence interval (CI): 0.72–1.41) in women who experienced exposure to passive smoking at work, 1.88 (95% CI: 1.38–2.55) in women who had exposure at home, and 2.80 (95% CI: 1.84–4.25) in women who were exposed at home and at work, all compared with never exposed regularly. Increased risk was associated with longer exposure: women exposed ≤ 20 years and > 20 years had 1.27 (95% CI: 0.97–1.66) and 2.64 (95% CI: 1.87–3.74) times higher risk of breast cancer compared with never exposed (Ptrend receptor-positive breast cancer did not differ from that with hormone receptor-negative breast cancer (Pheterogeneity > 0.05). There was evidence of interaction between passive smoking intensity and menopausal status in both overall group (P = 0.02) and hormone receptor-positive breast cancer group (P receptor status with the strongest association in postmenopausal women.

    Since both muscle mass and strength performance are polygenic in nature, the current study compared four Genetic Predisposition Scores (GPS) in their ability to predict these phenotypes. Data were gathered within the framework of the first generation Flemish Policy Research Centre 'Sport, Physical Activity and Health' (2002-2004). Results are based on muscle characteristics data of 565 Flemish Caucasians (19-73 yr, 365 men). Skeletal muscle mass (SMM) was determined using bioelectrical impedance. The Biodex dynamometer was used to measure isometric (PTstatic120°) and isokinetic strength (PTdynamic60° and PTdynamic240°), ballistic movement speed (S20%) and muscular endurance (Work) of the knee extensors. Genotyping was done for 153 gene variants selected based on a literature search and the expression Quantitative Trait Loci of selected genes. Four GPS were designed: a total GPS (based on the sum of all 153 variants, each favorable allele = score 1), a data-driven and weighted GPS (respectively the sum of favorable alleles of those variants with significant b-coefficients in stepwise regression (GPSdd) and the sum of these variants weighted with their respective partial r² (GPSw)) and an elastic net GPS (based on the variants that were selected by an elastic net regularization; GPSen). It was found that four different models for a GPS were able to significantly predict up to ~7% of the variance in strength performance. GPSen made the best prediction of SMM and Work. However, this was not the case for the remaining strength performance parameters, where best predictions were made by GPSdd and GPSw.

    Full Text Available This paper reviews the physiological, biomechanical and health impacts of load carriage on the female soldier and extends to include issues acknowledged as impacting on the female athlete and hence the female soldier. Physiological factors such as fat mass, strength, aerobic endurance and biomechanical factors such as stride length and forward lean have the potential to increase the energy cost of load carriage and cause injury. The female athlete triad, iron deficiency, pelvic floor muscle dysfunction and military equipment issues can likewise reduce female soldier performance and increase injury risk. Research evidence is presented to inform the development and implementation of performance optimisation and injury prevention strategies. Discussed strategies include structured physical conditioning, improving nutrition and hydration practices and modification of load carriage equipment to meet female soldier requirements.

    Sexual behavior is a result of interaction of biology and psychology. Sexual excitement of the female can be triggered by stimulation of erotogenic areas; part of which is the clitoris. Female circumcision is done to minimize sexual desire and to preserve virginity. This procedure can lead to psychological trauma to the child; with anxiety, panic attacks and sense of humiliation. Cultural traditions and social pressures can affect as well the unexcised girl. Female circumcision can reduce fem...

  11. The evolution of female sex pheromones

    2013-08-01

    Full Text Available The role of female sex pheromones in natural selection, particularly as a means for species recognition to avoid the generation of hybrid offspring with low fitness, has been widely explored and is generally accepted by scholars. However, the significance of sex pheromones in shaping mate choice (sexual selection and in competition over breeding resources (social selection has been largely ignored. The effect of sexual selection on sex pheromones as a sexually dimorphic signaling trait has been discounted because the amount of pheromone released by females is typically minute, while the role of sex pheromones in competition over breeding resources (other than mates has not yet been considered. As a result of natural selection, variation in sex pheromones among females is expected to be low, and males are not expected to choose their mates among pheromone-releasing conspecific females. Sexual selection, on the other hand, should drive the increase in pheromone variance among females, and males are expected to choose females based on this variation. Moreover, social selection resulting from more general social interactions, for example competition among females for breeding sites and food, should also promote variance among female sex pheromones. Here, we review the current evidence for each of the three selection processes acting on sex pheromones of female moths as an advertising trait. We suggest that the three selection types are not mutually exclusive but rather act together to promote different fitness components in diverse ecological situations [Current Zoology 59 (4: 569–578, 2013].

    Earlier studies suggest that alpha2-adrenoceptor antagonists and dopamine receptor agonists may enhance sexual activity in human and nonhuman male primates. It is not known whether these compounds influence the sexual behavior of female primates. We determined whether the administration of a selective alpha2-adrenoceptor antagonist (atipamezole), a dopamine receptor agonist (apomorphine), or their combination to female Macaca arctoides (stumptail macaque) monkeys produces changes in sexual behavior of the female with a male. Following the administration of drugs to the female, the behavior of the female with a male stumptail was observed for 30 min. Atipamezole dose dependently (0.03-0.3 mg/kg im) increased short-time mounting behavior of the male and the total number of copulations. Apomorphine alone (0.125-0.25 mg/kg) or in combination with atipamezole had no significant effects on sexual behavior. The result indicates that a selective alpha2-adrenoceptor antagonist administered in the female stumptail increases sexual behavior of the male with the female. A plausible explanation for this finding is that a selective alpha2-adrenoceptor antagonist increases sexual arousal in female stumptails and this, possibly due to a change in psychosocial behavior of the female, triggers increased sexual activity in males.

  13. Psychosocial and sexual aspects of female circumcision

    Full Text Available Sexual behavior is a result of interaction of biology and psychology. Sexual excitement of the female can be triggered by stimulation of erotogenic areas; part of which is the clitoris. Female circumcision is done to minimize sexual desire and to preserve virginity. This procedure can lead to psychological trauma to the child; with anxiety, panic attacks and sense of humiliation. Cultural traditions and social pressures can affect as well the unexcised girl. Female circumcision can reduce female sexual response, and may lead to anorgasmia and even frigidity. This procedure is now prohibited by law in Egypt.

    The purpose of this study is to determine and compare the prevalence of codependency in a group of 77 female and a group of 72 male helping professionals. Relatively low rates of codependency were observed in this sample, and the five-factor structure of the Codependency Assessment Tool (CODAT) was replicated. Males showed slightly higher codependency than females on the total CODAT and on the Hiding Self and Family of Origin Issues subscales. The CODAT was shown to be relevant to both males and females. Further research is needed to determine if a general population of male and female subjects would yield similar results.

    Transplantation of gynecological organs is a medical field where considerable advancements have been made in research during the last 25 years and with some procedures already introduced as clinical treatments. These types of transplantations aim at curing permanent infertility. Uterus transplantation has been proven to be a feasible procedure in different experimentation animal models with proof of concept concerning surgery, control of rejection and fertility. There has already been one human transplantation attempt, which, however, was unsuccessful. Based on the progress in this area, we predict that the first successful uterus transplantation attempt will come within 2-3 years. Orthotopic ovarian cortex transplantation has overcome the status of an experimental procedure since more than 20 pregnancies have been reported. Its main field of application is fertility preservation in oncologic patients undergoing high gonadotoxic risk therapies. The role of heterotopic ovarian cortex transplantation still remains at the research level, although co-transplantation with an orthotopic cortex might facilitate a more accurate endocrine environment. The major drawback of ovarian cortex transplantation remains the long ischemic interval between re-implantation and the establishment of neovascularization. Whole ovary cryopreservation followed by transplantation through vascular anastomosis may emerge as an important procedure in this field, because the warm ischemic time would be reduced from several days to less than 1 h, which will most likely improve follicle survival. In summary, transplantation surgery is also entering the field of gynecology and in the future several types of transplantations of organs/tissues of the female reproductive tract may become established clinical procedures.

    Aim: To study the multiple dose clinical pharmacokinetics of risperidone and its main active metabolite, 9-hydroxyrisperidone, in Chinese female patients with schizophrenia. Methods: The subjects were 23 Chinese female inpatients aged 18-65 years who met the CCMD-Ⅲ (third revision of the Chinese Criteria of Mental Disorders) criteria for schizophrenia. Subjects were tested after 17 d of treatment with 2 mg risperidone twice daily. Plasma concentrations of risperidone and 9-hydroxy-risperidone were assayed by using validated high performance liquid chromatography-mass spectrometry (HPLC-MS) methods. Results: Risperidone was rapidly absorbed (Tmax was 1.6 h) and its Tin in plasma was short (3.2 h).9-hydroxy-risperidone was quickly metabolized from the parent drug with a mean Tmax of 2.5 h. It had a long half-life of 24.7 h. The Cssav of risperidone and 9-hydroxyrisperidone were 36.9±33.1 and 110.6±30.5 μg·h·L-1, respectively, and the AUCss0-12 were 443.2±397.4 and 1327.2±402.3 μg·h·L-1, respectively. CL/F and V/F of risperidone were 8.7±6.2 L/h and 34.1±24.3 L, respectively. Interindividual variations for pharmacokinetic parameters were quite large for risperidone. All 23 subjects experienced high prolactin levels when treated with risperidone. However there was no correlation between prolactin level and the concentration of risperidone, 9-hydroxy-risperidone, or the active moiety. Conclusion: Risperidone showed large interindividual variations in pharmacokinetics. Administration of risperidone resulted in high serum prolactin levels. The results indicate that systemic exposure to risperidone and 9-hydroxy-risperidone in female Chinese schizophrenic patients is higher relative to published data for white Caucasian patients. Larger studies regarding the PK/PD relationship may be required to develop a reasonable clinical dosage regimen for Chinese female patients.

  17. Cryptic female exaggeration: the asymmetric female internal genitalia of Kaliana yuruani (Araneae: Pholcidae).

    Huber, Bernhard A

    2006-06-01

    Males of the Venezuelan pholcid spider Kaliana yuruani have unique genitalia, with the procursi about six times as long as usual in the family. The present article describes the previously unknown female, searching for a morphological correlate in the female genitalia to the male's exaggeration. Reconstruction of histological serial sections reveals an internal female complexity that is unequalled in pholcid spiders. An intricate system of ducts and folds is arranged in an asymmetric way, making this the third known case of genital asymmetry in spiders. The term "cryptic female exaggeration" is used in analogy to cryptic female choice, pointing to the fact that from the outside, the female genitalia do not appear unusual. I propose that cryptic female exaggeration may be relatively common in copulatory structures if male exaggerations need to be evaluated according to the female choice by mechanical fit model. Finally, the evolution of genital asymmetry in spiders is contrasted with that in insects.

    2014-01-01

    Female caribou (Rangifer tarandus) are highly gregarious, yet there has been little study of the behavioral mechanisms that foster coexistence. Quantifying patterns of aggression between male and female, particularly in the only cervid taxa where both sexes grow antlers, should provide insight into these mechanisms. We asked if patterns of aggression by male and female caribou followed the pattern typically noted in other polygynous cervids, in which males display higher frequencies and intensity of aggression. From June to August in 2011 and 2012, we measured the frequency and intensity of aggression across a range of group sizes through focal animal sampling of 170 caribou (64 males and 106 females) on Adak Island in the Aleutian Archipelago, Alaska. Males in same-sex and mixed-sex groups and females in mixed-sex groups had higher frequencies of aggression than females in same-sex groups. Group size did not influence frequency of aggression. Males displayed more intense aggression than females. Frequent aggression in mixed-sex groups probably reflects lower tolerance of males for animals in close proximity. Female caribou were less aggressive and more gregarious than males, as in other polygynous cervid species.

    2014-01-01

    Full Text Available The subject matter of this paper is an analysis of stereotypical social reactions to women’s alcoholism in the micro and macro social and cultural environment. The social stigma and blame that female alcohol abusers are exposed to have become part of deeply rooted gender-related labels. In a broader social context, they lead to discrimination and social exclusion. In the contemporary society, female alcoholism is turning into a growing social and health problem and because of that it is essential to make the social environment more sensitive to the issue of female alcoholism in order to eliminate the causes of female alcoholism and fully support women’s medical treatment,. It would have a preventive effect in suppressing female alcoholism and it would significantly reduce victimization of women who are, in such circumstances, much more vulnerable and exposed to physical and sexual violence. The aim of this paper is to point out to the basic phenomenological and etiological feature of female alcoholism, prejudices and stereotypical attitudes they are exposed to, social and cultural implications of female alcoholism, which is perceived as a predisposition for women’s victimization and exposure to violence, so as to promote a different social approach to female alcoholism and advocate for instituting social and educational policy based on the concept of gender equality and support of social control measures.

    State fish and wildlife agencies are particularly interested in attracting female participation because of the potential to offset declining participation in hunting. Understanding female hunters’ motivations will be critical for designing effective recruitment and retention programs for women hunters. Although female participation in hunting is increasing, males still outnumber females by about tenfold. Gender differences in deer hunters were explored by comparing ratings of eight motivations (social, nature, excitement, meat, challenge, trophy, extra hunting opportunity, and solitude). Hunter types were defined by hunters’ selection of the most important motivation for why they like Black Hills deer hunting. Overall, females and males were relatively similar in their ratings of the eight motivations, and we found 85% gender similarity in the selection of the most important motivation. Women were slightly more motivated by the food aspect of the hunt while men placed slightly more value on the hunt as a sporting activity.

    2015-07-01

    After the passage of Title IX in 1972, female sports participation skyrocketed. In 1992, the female athlete triad was first defined; diagnosis required the presence of an eating disorder, amenorrhea, and osteoporosis. However, many athletes remained undiagnosed because they did not meet all three of these criteria. In 2007, the definition was modified to a spectrum disorder involving low energy availability (with or without disordered eating), menstrual dysfunction, and low bone mineral density. With the new definition, all three components need not be present for a diagnosis of female athlete triad. Studies using the 1992 definition of the disorder demonstrated a prevalence of 1% to 4% in athletes. However, in certain sports, many female athletes may meet at least one of these criteria. The actual prevalence of athletes who fall under the "umbrella" diagnosis of the female athlete triad remains unknown.

    To test whether male body size affects female reproductive investment in the polygamous crayfish Procambarus clarkii, we described mating behaviour of virgin females paired with either small or large males, and analysed the number, size and weight of both eggs and juveniles sired by either types of male. Along with confirming the overt selection by females of larger mates, we found that the size and weight of both the eggs and the juveniles were higher when sired by larger fathers. This suggests that P. clarkii females exert a form of cryptic choice for large males, seemingly adjusting the quantity of egg deutoplasm in function of the mate body size. The question of why females spend time and energy to brood low-fitness offspring is finally raised.

    Full Text Available There are many factors related to female entering the labor market. For example, household income, household expenditure, education and status of the head of the household (male/ female. The degree of correlation between each variable and female labor force participation rate varies throughout the country. This study focused on the factors due to which women enter in labor market. Tobit model is used for this analysis. It is concluded that education and household expenditures have positive but insignificant impact on the female LF, whereas household income and head of the household has negative impact on FLF. It is suggested that in order to improve the working condition of female labor force government should take necessary action, for example women education etc.

  14. Female sexuality, regulation and resistance.

    India was the context for this discussion of female sexuality, rigid social norms, women's strategies for resistance, the evolution of norms from colonial India, prostitution, myths, and self-help women's activities. Sexuality is a changing set of ideas, and women have contributed to the redefinition. The biological view without consideration of the sociocultural and historical influences proscribes what is deviant and may be used to reinforce patriarchy and colonialism. Management and control of sexuality has been influenced by class, religion, caste, and ethnicity. During the colonial period, women's sexuality and treatment was challenged by the missionaries. The abolishment of "sati" as a traditional practice was used by the British to expand their rule and control over a wider regional area. Attempts were also made to regulate prostitution as means of protecting the health of the British army. The law requiring registration, examination, and commitment for treatment of prostitutes was not adhered to by the women involved. The notion of mothers as irresponsible came into being about 1900, and encouraged abandonment of traditional child- rearing ways for the Western standard of health and hygiene, and lifestyle. In Bengal, motherhood and mother qoddesses became the symbol of the liberation movement. The maternal role could be strengthened through education. The notion of mother and nationhood was supported by the women's movement in Great Britain and the US through positive eugenics ideas of quality race, which supported the ruling elite of British and Indians. Thus, the high class women were to be protected from early marriage, and encouraged to produce children fit to govern; the poor were to be protected from prostitution and overpopulation. Post colonial ideas about sexuality reflected a number of influences both from within and outside India. Health was a focus, and program targets were those who were outside the norm: women with too many children

    Fishburne, J I

    1983-04-01

    This issue of the Bulletin deals with the principles of anesthesia for outpatient female sterilization with emphasis on techniques for laparoscopy and minilaparotomy. General anesthesia techniques provide analgesia, amnesia, and muscle relaxation and are particularly useful for managing the anxious patient. Disadvantages include increased expense, need for specialized equipment, and highly trained personnel, and delayed recovery. Complications, though relatively rare, can be life-threatening and include aspiration of stomach contents, hypoxia, hypercarbia, hypotension, hypertension, cardiac arrhythmias, cardiorespiratory arrest, and death. There is no single preferred technique of general anesthesia, athough most anesthetists employ methods that allow rapid recovery of faculties, enabling the patient to be discharged soon after surgery. To accomplish this end, light anesthesia with sodium thiopental induction and nitrous oxide maintenance is often used. Short duration muscle relaxation with an agent such as succinylcholine supplements this technique. Other techniques include light anesthesia with inhalational anesthetic agents and the use of intravenous ketamine. Local anesthesia augmented by systemic and/or inhalational analgesia is supplanting general anesthesia techniques for laparoscopy in many locales. This approach is also particularly well-suited for minilaparotomy in developing countries, where it has achieved its greatest popularity. The local technique carries with it reduced morbidity and mortality but may not entirely relieve discomfort. The primary danger of local anesthesia is respiratory depression due to excessive narcosis and sedation. The operator must be alert to the action of the drugs and should always use the minimal effective dose. Although toxicity due to overdosage with local anesthetic drugs is occasionally experienced, allergic reactions to the amide-linkage drugs such as lidocaine or bupivacaine are exceedingly rare.

    Full Text Available Background: The pursuit of sexual pleasure is a key motivating factor in sexual activity. Many things can stand in the way of sexual orgasms and enjoyment, particularly among women. These are essential issues of sexual well-being and gender equality. Objective: This study presents long-term trends and determinants of female orgasms in Finland. The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner’s sexual techniques. Design: In Finland, five national sex surveys that are based on random samples from the central population register have been conducted. They are representative of the total population within the age range of 18–54 years in 1971 (N=2,152, 18–74 years in 1992 (N=2,250, 18–81 years in 1999 (N=1,496, 18–74 years in 2007 (N=2,590, and 18–79 years in 2015 (N=2,150. Another dataset of 2,049 women in the age group of 18–70 years was collected in 2015 via a national Internet panel. Results: Contrary to expectations, women did not have orgasms that are more frequent by increasing their experience and practice of masturbation, or by experimenting with different partners in their lifetime. The keys to their more frequent orgasms lay in mental and relationship factors. These factors and capacities included orgasm importance, sexual desire, sexual self-esteem, and openness of sexual communication with partners. Women valued their partner’s orgasm more than their own. In addition, positive determinants were the ability to concentrate, mutual sexual initiations, and partner’s good sexual techniques. A relationship that felt good and worked well emotionally, and where sex was approached openly and appreciatively, promoted orgasms.

    In lizards, the role of gravid oviparous females in controlling the temperature experienced by developing embryos prior to oviposition has been rarely examined. In particular, relatively little is known about the effect of gravidity on the thermal ecology of female Anolis lizards. Here we examine the thermal ecology of Anolis nebulosus from Nayarit, Mexico, with a particular goal of comparing the thermal ecology of gravid females to that of non-gravid females and males. The thermal efficiency (E) of gravid female A. nebulosus (E=0.782) was higher than in males (E=0.464), and to a lesser extent, non-gravid females (E=0.637), despite no significant differences observed in body, air, operative, or set point temperatures among males, gravid females, and non-gravid females. Gravid females had smaller differences between body temperatures and set point temperatures (db), but did not differ in the difference between operative temperature and set point temperature (de). Gravid females used sun-shade and shaded microhabitats proportionately more than males and non-gravid females, and rarely used sunny microhabitats. Our results suggest that gravid A. nebulosus are using a different and more efficient thermoregulatory strategy than other adults in the population. Such efficient thermoregulation is possibly related to females attempting to provide a thermal environment that is conducive to the development of embryos in eggs prior to oviposition.

    In preclinical studies screening for novel antidepressants, male and female animals should be used. However, in a widely used antidepressant test, the forced swim test (FST), sex differences between males and females are not consistent. These discrepancies may discourage the inclusion of females in FST studies. In order to overcome this problem and provide a detailed insight regarding the use of female animals in the FST, we designed the following experiment and we performed a thorough analysis of the relevant literature. Male and female Wistar adult rats were subjected to the FST and sertraline was used as an antidepressant in two doses (10 mg/kg and 40 mg/kg, 3 injections in 24 h). Rodents were subjected in the two FST sessions during all possible combinations of the estrous cycle stages. We found that females exhibited higher levels of immobility than males and this sex difference was alleviated following antidepressant treatment. Sertraline at both doses enhanced swimming in both sexes, but females appeared more responsive to lower sertraline doses regarding immobility levels. Surprisingly, the high sertraline dose enhanced climbing particularly in proestrous and diestrous. Marked sex differences were also observed in the frequency of head swinging, with females exhibiting lower counts than males. Conclusively, when screening for new antidepressants, it is recommended to use standard FST procedures and if possible to include females in all phases of the cycle. Using only one dose of an investigational drug in females in certain phases of the cycle could result to false negative results.

    Background: Data on selenium (Se) levels in American young adults, especially in African Americans, are lacking. Objective: This study presented toenail Se distributions in American young adults of both genders, including both Caucasians and African Americans; and explored potential predictors of toenail Se levels. Data and methods: Data from the Coronary Artery Risk Development in Young Adults study among 4252 American young adults, aged 20-32 in 1987 was used to examine toenail Se levels by instrumental neutron-activation analysis. The distribution of Se levels was described and multivariable linear regression was used to examine potential modifiers of toenail Se concentration within ethnicity-gender subgroups. Results: The geometric mean of toenail Se in this cohort was 0.844 {mu}g/g (95% CI, 0.840-0.849 {mu}g/g) and the median was 0.837 {mu}g/g (95% CI, 0.833-0.844 {mu}g/g). Median levels from lowest to highest quintile were 0.691, 0.774, 0.838, 0.913 and 1.037 {mu}g/g. Se levels varied geographically, and were generally in accordance with its concentrations in local soil. Males, African Americans, current smokers, heavy drinkers and less educated participants were more likely to have low Se levels. Conclusion: This study suggests that toenail Se levels vary geographically depending on soil Se concentrations. In addition to gender, ethnicity and education level, smoking status and alcohol consumption are two important indicators of Se status since they are modifiable lifestyle factors. Findings from this study might aid public health professionals in identifying people at relatively high or low Se levels, so that chronic disease prevention efforts can be directed toward these subgroups. - Research highlights: {yields} Average of toenail Se levels in this cohort was 0.844 {mu}g/g (95% CI, 0.840-0.849 {mu}g/g). {yields} Toenail Se levels vary geographically depending on soil Se concentrations. {yields} Males, African Americans and less educated participants have

    Graves disease (GB) is an autoimmune disease of the thyroid gland. Genes of, or closely associated to, the HLA complex are assumed to contribute to the genetic predisposition to GD. The authors have previously reported an increased frequency of HLA-DR3/DQ3 in Caucasian patients with GD, and recently the importance of Dw24 encoded by DRB3 gene has been suggested. To further investigate the associations of GD and these genes, 94 unrelated patients with GD and 75 control subjects were typed for HLA-DRB3, -DRB1, and -DQA1, and -DQB1, using sequence-specific oligonucleotide probes to analyze polymerase chain reaction amplified DNA (PCR-SSO). Three findings emerged from these studies. (1) The frequency of subjects positive for DQA1*0501 (GD, 73.4% vs. control 42.7%, P = 0.0001, RR = 3.71) was significantly increased among patients. The frequency of DR3 (GD, 34.0% vs. control 17.3%, P = 0.0146, RR = 2.46), which is in tight linkage disequilibrium with DQA1*0501, was also increased; however, it was not significant when the P value was corrected for the number of antigens tested. Neither DQB1 nor DRB3 alleles were significantly increased in frequency. (2) After exclusion of DR3-positive subjects, DQA1*0501 was still significantly increased (GD, 59.7% vs. control 30.6%, P = 0.0012, Pc < 0.01, RR = 3.35) among patients. (3) The distributions of Dw24 and Dw25,26 (Dw25 or Dw26) did not differ between patients and controls on either DR3 positive or negative groups. These findings suggest the DQA1*0501, or a closely associated unknown gene, confers susceptibility to GD, while Dw24 is not directly involved. The importance of DR3, however, remains to be elucidated, because of the fixed linkage with DQA1*0501. 34 refs., 1 fig., 5 tabs.

    As part of the insulin signaling pathway, AKT influences growth and metabolism. The AKT1 gene G205T (rs1130214) polymorphism has potential functional effects. Thus, we determined whether the G205T polymorphism influences metabolic variables and their responses to aerobic exercise training. Following dietary stabilization, healthy, sedentary, 50-75 yr old Caucasian men (n = 51) and women (n = 58) underwent 6 months of aerobic exercise training. Before and after completing the intervention, dual-energy x-ray absorptiometry measured percent body fat, computed tomography measured visceral and subcutaneous fat, and oral glucose tolerance testing measured glucose total area under the curve (AUC), insulin AUC, and insulin sensitivity. Taqman assay determined AKT1 G205T genotypes. At baseline, men with the GG genotype (n = 29) had lower VO2max values (p = 0.026), and higher percent body fat (p = 0.046), subcutaneous fat (p = 0.021), and insulin AUC (p = 0.003) values than T allele carriers (n = 22). Despite their rather disadvantageous starting values, men with the GG genotype seemed to respond to exercise training more robustly than men with the T allele, highlighted by significantly greater fold change improvements in insulin AUC (p = 0.012) and glucose AUC (p = 0.035). Although the GG group also significantly improved VO2max with training, the change in VO2max was not as great as that of the T allele carriers (p = 0.037). In contrast, after accounting for hormone replacement therapy use, none of the variables differed in the women at baseline. As a result of exercise training, women with the T allele (n = 20) had greater fold change improvements in fasting glucose (p = 0.011), glucose AUC (p = 0.017), and insulin sensitivity (p = 0.044) than GG genotype women (n = 38). Our results suggest that the AKT1 G205T polymorphism influences metabolic variables and their responses to aerobic exercise training in older previously sedentary individuals. PMID:21097644

    Background and Aims: Global estimates of overweight and obesity prevalence are based on the World Health Organisation (WHO) body mass index (BMI) cut-off values of 25 and 30 kg m−2, respectively. To validate these BMI cut-offs for adiposity in the island population of Mauritius, we assessed the relationship between BMI and measured body fat mass in this population according to gender and ethnicity. Methods: In 175 young adult Mauritians (age 20-42 years) belonging to the two main ethnic groups—Indians (South Asian descent) and Creoles (African/Malagasy descent), body weight, height and waist circumference (WC) were measured, total body fat assessed by deuterium oxide (D2O) dilution and trunk (abdominal) fat by segmental bioimpedance analysis. Results: Compared to body fat% predicted from BMI using Caucasian-based equations, body fat% assessed by D2O dilution in Mauritians was higher by 3–5 units in Indian men and women as well as in Creole women, but not in Creole men. This gender-specific ethnic difference in body composition between Indians and Creoles is reflected in their BMI–Fat% relationships, as well as in their WC–Trunk Fat% relationships. Overall, WHO BMI cut-offs of 25 and 30 kg m−2 for overweight and obesity, respectively, seem valid only for Creole men (~24 and 29.5, respectively), but not for Creole women whose BMI cut-offs are 2–4 units lower (21–22 for overweight; 27–28 for obese) nor for Indian men and women whose BMI cut-offs are 3–4 units lower (21–22 for overweight; 26–27 for obese). Conclusions: The use of BMI cut-off points for classifying overweight and obesity need to take into account both ethnicity and gender to avoid gross adiposity status misclassification in this population known to be at high risk for type-2 diabetes and cardiovascular diseases. This is particularly of importance in obesity prevention strategies both in clinical medicine and public health. PMID:27698347

    2007-09-01

    We investigated the associations between two CYP1A1 polymorphisms (Ile462Val and Thr461Asn) and one CYP1B1 polymorphism (Leu432Val) and breast cancer risk. The study population consisted of 483 breast cancer patients and 482 healthy population controls, all of homogenous Finnish origin. No statistically significant overall associations were found between the CYP1A1 and CYP1B1 genotypes and breast cancer risk. However, a significant increase in the breast cancer risk was seen for women who had smoked 1-9 cigarettes/day and carried the CYP1B1 432Val allele; the OR was 2.6 (95% CI 1.07-6.46) for women carrying the Leu/Val genotype and 5.1 (95% CI 1.30-19.89, P for trend 0.005) for women with the Val/Val genotype compared to similarly smoking women homozygous for the 432Leu allele. Furthermore, when CYP1B1 genotypes were combined with the previously analyzed N-acetyl transferase (NAT2) genotypes, a significant increase in breast cancer risk was found among women who had at least one CYP1B1 432Val allele together with the NAT2 slow acetylator genotype (OR 1.52; 95% CI 1.03-2.24) compared to women carrying a combination of CYP1B1 Leu/Leu and NAT2 rapid acetylator genotypes. This risk was seen to be confined to ever smokers; the OR was 2.46 (95% CI 1.11-5.45) for ever smokers carrying at least one CYP1B1 432Val allele together with the NAT2 slow acetylator genotype compared to ever smokers with the CYP1B1 Leu/Leu and NAT2 rapid acetylator genotype combination. Our results suggest that the CYP1B1 polymorphism may be an important modifier of breast cancer risk in Finnish Caucasian women who have been exposed to tobacco smoke and/or carry the NAT2 slow acetylator genotype.

NASA selected all six women as their first female astronaut candidates in January 1978, allowing them to enroll in a training program that they completed in August 1979. Shannon W. Lucid was born on January 14, 1943 in Shanghai, China but considers Bethany, Oklahoma to be her hometown. She spent many years at the University of Oklahoma, receiving a Bachelor in chemistry in 1963, a Master in biochemistry in 1970, and a Doctorate in biochemistry in 1973. Dr. Lucid flew on the STS-51G Discovery, STS-34 Atlantis, STS-43 Atlantis, and STS-58 Columbia shuttle missions, setting the record for female astronauts by logging 838 hours and 54 minutes in space. She also currently holds the United States single mission space flight endurance record for her 188 days on the Russian Space Station Mir. From February 2002 to September 2003, she served as chief scientist at NASA Headquarters before returning to JSC to help with the Return to Flight program after the STS-107 accident. Born November 8, 1947, in Murfreesboro, Tennessee, Margaret Rhea Seddon received a Doctorate of Medicine in 1973 from the University of Tennessee. She flew on space missions STS-51 Discovery, STS-40 Columbia, and STS-58 Columbia for a total of over 722 hours in space. Dr. Seddon retired from NASA in November 1997, taking on a position as the Assistant Chief Medical Officer of the Vanderbilt Medical Group in Nashville, Tennessee. Kathryn Sullivan was born October 3, 1951 in Patterson, New Jersey but considers Woodland Hills, California to be her hometown. She received a Bachelor in Earth Sciences from the University of California, Santa Cruz in 1973 and a Doctorate in Geology from Dalhousie University in Halifax, Nova Scotia in 1978.

    Full Text Available Waist-to-hip ratio (WHR and breast size are morphological traits that are associated with female attractiveness. Previous studies using line drawings of women have shown that men across cultures rate low WHRs (0.6 and 0.7 as most attractive. In this study, we used additional viewing measurements (i.e., first fixation duration and visual regressions to measure visual attention and record how long participants first focused on the female body and whether they regressed back to an area of interest. Additionally, we manipulated skin tone to determine whether they preferred light- or dark-skinned women. In two eye tracking experiments, participants rated the attractiveness of female nude images varying in WHR (0.5–0.9, breast size, and skin tone. We measured first fixation duration, gaze duration, and total time. The overall results of both studies revealed that visual attention fell mostly on the face, the breasts, and the midriff of the female body, supporting the evolutionary view that reproductively relevant regions of the female body are important to female attractiveness. Because the stimuli varied in skin tone and the participants were mainly Hispanic of Mexican American descent, the findings from these studies also support a preference for low WHRs and reproductively relevant regions of the female body.

  9. Female Clergy as Agents of Religious Change?

    Full Text Available This article focuses on female clergy as potential agents of change in the Church. I argue that the adoption of female clergy is one of the main factors that cause the Church to change its practices, policies and theological orientation. The first female ministers were ordained in the Evangelical Lutheran Church of Finland in 1988. This is fairly late compared to other Nordic countries. However, the number of female ministers and female students has been growing fast and nowadays about 70 percent of theology students are female.The paper is based on quantitative surveys conducted among the members of the Clergy Union in 2002, 2006 and 2010 (N = about 1,000 each and among the applicants for university studies in theology in 2010. The research shows that clergywomen are changing the Church in a clearly more liberal direction. They do it in various areas of church life: they change the perception of faith and dogma, the policies of the Church as well as daily practices in parishes. Clergymen are notably more traditional in their orientation, even young clergymen. Therefore it is especially the female clergy who serve as agents of religious change in the Church.

  10. Female Sex Offenders: Public Awareness and Attributions.

    Traditional gender roles, sex scripts, and the way female sex offenders are portrayed in the media may lead to misconceptions about who can commit sexual offenses. Sexual crimes by women may go unnoticed or unreported if there is a general lack of awareness that females commit these crimes. Data from the 2012 Nebraska Annual Social Indicators Survey were used to determine whether the public perceives women as capable sex offenders and the perceived causes of female sex offending. The traditional focus on male sex offenders by researchers, media, and politicians, in addition to gender stereotypes, introduces the possibility of group differences (e.g., between men and women) in perceptions of female sex offenders. Consequently, two secondary analyses were conducted that tested for group differences in both the public's perception of whether females can commit sex offenses and the explanations selected for why females sexually offend. The findings suggest that the public does perceive women as capable sex offenders, although there were group differences in the causal attributions for female sex offending.

  11. The evolution of female sex pheromones

    The role of female sex pheromones in natural selection,particularly as a means for species recognition to avoid the generation of hybrid offspring with low fitness,has been widely explored and is generally accepted by scholars.However,the significance of sex pheromones in shaping mate choice (sexual selection) and in competition over breeding resources (social selection) has been largely ignored.The effect of sexual selection on sex pheromones as a sexually dimorphic signaling trait has been discounted because the amount of pheromone released by females is typically minute,while the role of sex pheromones in competition over breeding resources (other than mates) has not yet been considered.As a result of natural selection,variation in sex pheromones among females is expected to be low,and males are not expected to choose their mates among pheromone-releasing conspecific females.Sexual selection,on the other hand,should drive the increase in pheromone variance among females,and males are expected to choose females based on this variation.Moreover,social selection resulting from more general social interactions,for example competition among females for breeding sites and food,should also promote variance among female sex pheromones.Here,we review the current evidence for each of the three selection processes acting on sex pheromones of female moths as an advertising trait.We suggest that the three selection types are not mutually exclusive but rather act together to promote different fitness components in diverse ecological situations.

  12. Female urbanward migration and human resource issues.

    Zosa-feranil, I

    1990-01-01

    Of those migrating to urban centers in the Philippines, a disproportionate number of them are young females, most of whom end up working in the service sector. Between 1975-80, 1.3 million people migrated to urban centers, 56% of whom were females. Furthermore, a 1980 census indicates that 13% of all urban migrants were females age 15-19, and almost 1/4 of them were women in their 20s. Figures also show that single females make up a substantial portion of the urban migrants. Compared to the men migrating into the cities, the female urban migrants had lower educational attainments. Many of uneducated migrants do not integrate as easily, and are relegated to the periphery of urban centers. The search for employment serves as the driving force for urban migration, and in fact, the level of female participation in the workforce is high. But while male migrants work mostly as craftsmen or in the production sector, most female migrants work in the service sector. This category includes domestic workers, laundry women, cooks and waitresses, hospitality girls, and prostitutes. Generally attracting single, young females, the service sector has easy entry, which helps explain the high rate of female employment. The author explains that this trend is cause for concern, considering that the number of people involved is large, that the service sector provides low earning, and that it lends itself to the exploitation of the workers. Nonetheless, the author says that the migration pattern might only be transitory, and the urban migration might be a liberating process for women, but explains that further research is needed concerning the upward mobility of urban migrants.

    Few data exist on bone turnover in South Asian women and it is not well elucidated as to whether Western dwelling South Asian women have different bone resorption levels to that of women from European ethnic backgrounds. This study assessed bone resorption levels in UK dwelling South Asian and Caucasian women as well as evaluating whether seasonal variation in 25-hydroxyvitamin D [25(OH)D] is associated with bone resorption in either ethnic group. Data for seasonal measures of urinary N-telopeptide of collagen (uNTX) and serum 25(OH)D were analysed from n=373 women (four groups; South Asian postmenopausal n=44, South Asian premenopausal n=50, Caucasian postmenopausal n=144, Caucasian premenopausal n=135) (mean (±SD) age 48 (14) years; age range 18-79years) who participated in the longitudinal D-FINES (Diet, Food Intake, Nutrition and Exposure to the Sun in Southern England) cohort study (2006-2007). A mixed between-within subjects ANOVA (n=192) showed a between subjects effect of the four groups (PD was predictive of uNTX, with estimate (SD)=0.213 (0.015) and 95% CI (0.182, 0.245; PD, adjusted for overall 25(OH)D concentration, showed increased levels of uNTX. Although the effect size was smaller than for the amplitude/mesor ratio, the mesor for 25(OH)D concentration was also predictive of uNTX, with estimate (SD)=-0.035 (0.004), and 95% CI (-0.043, -0.028; PD concentration showed an increased bone resorption, an association which was larger than that of the 25(OH)D yearly average, suggesting it may be as important clinically to ensure a stable and steady 25(OH)D concentration, as well as one that is high enough to be optimal for bone health.

    Superb fairy-wren (Malurus cyaneus) females use an incubation call to teach their embryos a vocal password to solicit parental feeding care after hatching. We previously showed that high call rate by the female was correlated with high call similarity in fairy-wren chicks, but not in cuckoo chicks, and that parent birds more often fed chicks with high call similarity. Hosts should be selected to increase their defence behaviour when the risk of brood parasitism is highest, such as when cuckoos are present in the area. Therefore, we experimentally test whether hosts increase call rate to embryos in the presence of a singing Horsfield's bronze-cuckoo (Chalcites basalis). Female fairy-wrens increased incubation call rate when we experimentally broadcast cuckoo song near the nest. Embryos had higher call similarity when females had higher incubation call rate. We interpret the findings of increased call rate as increased teaching effort in response to a signal of threat.

    The aim of this study was to examine the relation between increased physical activity and menstrual disorders in adolescent female volleyball players. The study was conducted on 210 Polish female volleyball players, aged 13-17 years, the authorship questionnaire was used. The results of the study showed that irregular menstruation occurred in 19% of girls, spotting between menstrual periods in 27% and heavy menstruation was reported in 33% of girls. Out of all volleyball female players participating in the study, 94 girls (45%) declared absence of menstrual periods after regular cycles. Statistical analysis showed that the more training hours per week, the bigger probability of the occurrence of irregular menstruation. It was concluded that the number of hours of volleyball training per week affects regularity of menstrual cycles in female volleyball players. The absence of menstruation might be caused by the duration of training per week or years of training.

    Full Text Available Female genital mutilation (FGM, sometimes referred to as female circumcision or female genital cutting, is a harmful cultural practice without any known health benefit. Its short-term and long-term health risks have led to numerous initiatives toward its eradication at international and local levels, over the last two decades. While major challenges remain and millions of girls and women are still at risk of being subjected to FGM, there is growing evidence that interventions that take into account the social dynamics that perpetuate FGM are yielding positive results toward its reduction. Well-recognized as a human rights violation in international treaties, the elimination of female genital mutilation requires ongoing interventions through cross-sectoral approaches that address attitudinal, cultural and behavioral change.

    We examined the reproductive performance of female caribou (Rangjfer tarandus granti) in relation to age, physical condition, and reproductive experience for 9 consecutive years (1987-95) at Denali National Park, Alaska, during a period of wide variation in winter snowfall. Caribou in Denali differed from other cervid populations where reproductive performance has been investigated, because they occur at low densities (less than or equal to 0.3/km(2)) and experience high losses of young to predation. Females first gave birth at 2-6 years old; 56% of these females were 3 years old. Average annual natality rates increased from 27% for 2-year-olds to 100% for 7-year-olds, remained high for 7-13-year-olds (98%), and then declined for females greater than or equal to 14 years old. Females greater than or equal to 2 years old that failed to reproduce were primarily sexually immature (76%). Reproductive pauses of sexually mature females occurred predominantly in young (3-6 yr old) and old (greater than or equal to 14 yr old) females. Natality increased with body mass for 10-month-old females weighed 6 months prior to the autumn breeding season (P = 0.007), and for females >1 year old and weighed during autumn (late Sep-early Nov; P = 0.003). Natality for 2-, 3-, 4-, and 6-year-olds declined with increasing late-winter snowfall (Feb-May; P less than or equal to 0.039) during the winter prior to breeding. In most years, a high percentage of sexually mature females reproduced, and lactation status at die time of breeding did not influence productivity the following year. However, following particularly high snowfall during February-September 1992, productivity was reduced in 1993 for cows successfully rearing calves to autumn the precious year. High losses of calves to predators in 1992 may have increased productivity in 1993. Losses of young-of-the year to predation prior to the annual breeding season can be an important influence on subsequent productivity for ungulate

    This paper reviews some of the types of autoerotic death which have been reported and some of the psychodynamic principles which are associated with them. As cases involving females have never been reported, this presentation offers some opportunity to see how psychiatric insight assisted police investigation of an autoerotic death. Crime scene sketching and photographic evidence complement the case material so that the reader can feel he is at the crime scene. A comparison between male and female autoerotic deaths is made.

  9. Mates of Competitive Females: The Relationships between Female Aggression, Mate Quality, and Parental Care

    Full Text Available Though rarely mate-limited, females in a wide variety of species express traits commonly associated with mate competition in males. Recent research has shown that these competitive traits (ornaments, armaments, and intense aggression often function in the context of female-female competition for nonsexual reproductive resources and are often positively related to reproductive success. Increased success could occur because competitive females acquire limited ecological resources (nest sites, territories, etc. or because they pair with high quality males, that is, older, more ornamented, or more parental males. Further, males paired with aggressive/low care females may compensate by increasing their paternal efforts. Here, I examined patterns of social pairing and parental care in free-living dark-eyed juncos (Junco hyemalis, a biparental songbird. I found no detectable relationship between female competitive behavior (aggression and male quality (age, size, or ornamentation or male provisioning. Thus, neither of the mate choice hypotheses (females compete for males or males prefer aggressive females was supported. Instead, these results suggest that females compete for nonsexual resources and mate quality is a secondary consideration. I also found a negative relationship between male and female provisioning rates, suggesting that partners adjust their level of parental effort in response to their partner’s efforts.

  10. Aggression by ovariectomized female rats with testosterone implants: competitive experience activates aggression toward unfamiliar females.

    Female hooded rats (250 to 325 g) were ovariectomized and bilaterally implanted with testosterone-filled or empty Silastic tubes. The testosterone-filled space in each tube was 10 mm long and this should produce a serum testosterone concentration 4 to 5 times that of an intact female, but well below that of a male. Three weeks following surgery, half of the animals with testosterone implants were housed with an animal with an empty implant and left for 6 weeks. The remaining animals were placed on a 23-hr food deprivation schedule, housed in testosterone implant/empty implant pairs, and then subjected to a series of food competition tests. Following the competition tests, all animals were individually tested in their living cage for aggression toward an unfamiliar female. In food competition, females with testosterone implants were more successful and more aggressive than their cagemates with empty implants. When tested for aggression toward an unfamiliar intruder, females with testosterone implants given competitive experience were more aggressive toward an intruder than were their cagemates with empty implants or females with testosterone implants not given the competitive experience. Females with testosterone implants but without competitive experience were not more aggressive toward an unfamiliar female than were their cagemates with empty implants. These results suggest that, in ovariectomized females with testosterone implants, hormone-dependent aggression fostered by a competitive situation is displayed toward unfamiliar females.

  11. Photoperiod and reproduction in female deer mice

    1982-03-01

    Female deer mice were exposed to a short day photoperiod beginning during 1 of 3 stages of life. In the first experiment, exposure to SD during adulthood resulted in a minimal disruption of reproductive condition; many females bore 2 litters after the onset of this treatment. In the second experiment, females reared on SD from weaning matured normally, as measured by vaginal introitus; however, vaginal closure occurred in approximately one-half of these females by 9 weeks of age. In the third experiment, females were born of mothers housed on either an SD or a long day photoperiod, and were continued on the maternal photoperiod until 6 weeks of postnatal age. The SD photoperiod markedly inhibited reproductive maturation as measured by vaginal patency, ovarian weight, and uterine weight. A comparison of reproductive organ weights and vaginal condition provided evidence for the validity of the latter measure as an index of reproductive state. As assayed by the present testing procedure, the sensitivity of the reproductive system to photoperiod decreases as a function of age in female deer mice.

  12. Genital evolution: why are females still understudied?

    The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias.

  14. Females excel at basic face perception.

    Females are generally better than males at recognizing facial emotions. However, it is not entirely clear whether and in what way females may also excel at non-affective face recognition. Here, we tested males and females on two perceptual face recognition tasks that involved only neutral expressions: detection and identity discrimination. On face detection (Experiment 1), females were significantly more accurate than males in detecting upright faces. This gender difference was reduced during inverted face detection, and not present during tree detection, suggesting that the magnitude of the gender difference for performance co-varies with the extent to which face processing mechanisms are involved. On facial identity discrimination (Experiment 2), females again outperformed males, particularly when face images were masked by visual noise, or the delay between comparison face images was extended from 0.5 to 3s. These results reveal a female advantage in processing face-specific information and underscore the role of perceptual factors in socially relevant gender differences.

  15. Community-based science education for fourth to sixth graders: Influences of a female role model

    Acklie, Deanna S.

    Women in the United States are underrepresented in science related careers. The Wonderwise curriculum was designed to encourage young women to become more involved in science and science careers. The Wonderwise kits have won numerous awards for quality science curriculum for formal educational environments. In 2000 the kits were adapted and new kits were developed to meet the needs of a nonformal Teaming environment (i.e., 4-H). The kits contain a video field trip with a featured female scientist demonstrating her work, an activity guidebook with five activities based on this scientist's work, and a CD-Rom serving as an additional resource. This study contributes to our understanding of a group of 4H youth who used the Wonderwise curriculum. It describes their view on science, their perspective about people who do science, the importance of role models within their lives, and their career visions. This study was a multi-method case study design. The subjects were youth ages 9--11 involved in 4H events in a three state area. Events such as overnight camps, day camps, special events and after school programs featuring the Wonderwise curriculum were used as sites for this study. The subjects studied in the Wonderwise 4-H project were primarily female youth who had some interest in science. Nearly half were Caucasian; the remainder were Hispanic, African American and Native American. The 25 youth involved in this study took part in a semi-structure interview process including four research methodologies: open-ended questions, drawing or writing a story about the featured scientist, a card sort activity and a relationship map drawn by the youth. Youths' prior experiences in formal, informal and nonformal settings impacted how they made sense of and incorporated Wonderwise experiences in their frame of reference. Through the experiential learning process youth experienced science activities and connected to individuals with science backgrounds, particularly those

  16. Female heterozygotes for the hypomorphic R40H mutation can have ornithine transcarbamylase deficiency and present in early adolescence: a case report and review of the literature

    Full Text Available Abstract Introduction Ornithine transcarbamylase deficiency is the most common hereditary urea cycle defect. It is inherited in an X-linked manner and classically presents in neonates with encephalopathy and hyperammonemia in males. Females and males with hypomorphic mutations present later, sometimes in adulthood, with episodes that are frequently fatal. Case presentation A 13-year-old Caucasian girl presented with progressive encephalopathy, hyperammonemic coma and lactic acidosis. She had a history of intermittent regular episodes of nausea and vomiting from seven years of age, previously diagnosed as abdominal migraines. At presentation she was hyperammonemic (ammonia 477 μmol/L with no other biochemical indicators of hepatic dysfunction or damage and had grossly elevated urinary orotate (orotate/creatinine ratio 1.866 μmol/mmol creatinine, reference range A mutation was identified in the ornithine transcarbamylase gene (OTC in our patient confirming the first symptomatic female shown heterozygous for the R40H mutation. A review of the literature and correspondence with authors of patients with the R40H mutation identified one other symptomatic female patient who died of hyperammonemic coma in her late teens. Conclusions This report expands the clinical spectrum of presentation of ornithine transcarbamylase deficiency to female heterozygotes for the hypomorphic R40H OTC mutation. Although this mutation is usually associated with a mild phenotype, females with this mutation can present with acute decompensation, which can be fatal. Ornithine transcarbamylase deficiency should be considered in the differential diagnosis of unexplained acute confusion, even without a suggestive family history.

    Full Text Available Background: The clinical and histological presentation of spongiotic dermatitis and its inflammatory infiltrates warrant further investigation. In this case documentation of a patient with cutaneous spongiotic reactivity, we aim to characterize antigen presenting cells, as well as the skin-specific cutaneous lymphocyte antigen population by multiple techniques. Case report: A 30 year old Caucasian female presented with a two week history of blistering and erosions around the vaginal, rectal and axillary areas. Material and Methods: We utilized hematoxylin and eosin histology, direct immunofluorescence, immunohistochemistry and confocal microscopy methods to evaluate the immune reaction patterns of the cutaneous inflammatory cells. Results: In the primary histologic areas of spongiotic dermatitis, a mixed population of B and T lymphocytes was seen. Ki-67 antigen proliferative index staining was accentuated in these areas, correlating with the presence of large numbers of epidermal and dermal antigen presenting cells. Among the antigen presenting cell population, we detected strong positivities with CD1a, Factor XIIIa, myeloid/hystoid antigen, S100, HAM-56, and CD68. Interestingly, immunoglobulins G, D and M and Complement factors C1q and C3 were also strongly expressed in antigen presenting cell areas, including positivity within the spongiotic epidermis and around dermal vessels. Conclusions: We document a heterogeneous population of B and T lymphocytes and the presence of multiple classes of antigen presenting cells, immunoglobulins and complement in and surrounding histologically spongiotic areas; these findings further correlated with increased levels of expression of Ki-67.

    The thrombophilic genetic factors (THRGFs), PAI-1 4G-4G, MTHFR 677TT, V Leiden 506Q and Prothrombin 20210A, were studied as risk factors in 865 Caucasian patients with liver cirrhosis, consecutively enrolled from June 2008 to January 2014. A total of 582 HCV, 80 HBV, 94 alcohol, (82 with more than one etiologic factor) and 191 cryptogenic patients with liver cirrhosis had been consecutively enrolled; 243 patients showed portal vein thrombosis (PVT). At least one of the above THRGFs was present in 339/865 patients (39.2%). PAI-1 4G-4G and MTHFR 677TT were the most frequent THRGFs, statistically significant in patients with alcohol, cryptogenic liver cirrhosis, and PVT: respectively 24 and 28, 50 and 73, and 65 and 83 (all chi-square tests>3.84, and p valuesPAI-1 4G-4G and MTHFR 677TT, as dependent variable, confirmed the independent significant relationship of these THRGFs with alcohol, cryptogenic liver cirrhosis and PVT. PAI 1 and MTHFR 677 genotypes, deviated from those expected in populations in Hardy-Weinberg equilibrium (all p valuesPAI-1 4G-4G and MTHFR 677TT in patients with alcohol, cryptogenic liver cirrhosis, and PVT, in a Caucasian population. In conclusion, thrombo and fibro-genetic mechanisms of PAI-1 4G-4G and MTHFR 677TT, could have a role in the development of liver cirrhosis, mainly in patients without HCV and HBV, and PVT.

    Memory and executive functioning are two important components of clinical neuropsychological (NP) practice and research. Multiple demographic factors are known to affect performance differentially on most NP tests, but adequate normative corrections, inclusive of race/ethnicity, are not available for many widely used instruments. This study compared demographic contributions for widely used tests of verbal and visual learning and memory (Brief Visual Memory Test-Revised, Hopkins Verbal Memory Test-Revised) and executive functioning (Stroop Color and Word Test, Wisconsin Card Sorting Test-64) in groups of healthy Caucasians (n = 143) and African Americans (n = 103). Demographic factors of age, education, gender, and race/ethnicity were found to be significant factors on some indices of all four tests. The magnitude of demographic contributions (especially age) was greater for African Americans than for Caucasians on most measures. New, demographically corrected T-score formulas were calculated for each race/ethnicity. The rates of NP impairment using previously published normative standards significantly overestimated NP impairment in African Americans. Utilizing the new demographic corrections developed and presented herein, NP impairment rates were comparable between the two race/ethnicities and were unrelated to the other demographic characteristics (age, education, gender) in either race/ethnicity group. Findings support the need to consider extended demographic contributions to neuropsychological test performance in clinical and research settings.

    The analysis of families collected by the T1DGC and typed at high resolution for the HLA class I and class II loci provided an opportunity for identifying new alleles and rare recombination events. In one American Caucasian family, a novel allele (HLA-DPB1*1302), detected as an unusual pattern of probe binding, was identified in the mother and in one child. Amplicons from both individuals were sequenced and a new variant of DPB1*1301 with an A->T mutation [TAC to TTC in codon 64, (amino acid 35); Y to F] was confirmed. In another American Caucasian family, one child inherited an unusual haplotype, DRB1*1501-DQA1*0102-DQB1*0609-DPA1*0103-DPB1*0601 resulting from a recombination between the DRB1 loci on the maternal chromosomes DRB1*1501-DQA1*0102-DQB1*0602-DPA1*0103-DPB1*0401 and DRB1*1302-DQA1*0102-DQB1*0609-DPA1*0103-DPB1*0601.
