    Full Text Available Screened fiction stirs people’s psyches through emotions, which refer to a virtual world and therefore have the potential to help the individual grow in self-awareness while feeling relatively “safe”. An innovative method to work on movies for education and training purposes was developed by Eugenio Torre, and is proposed here for the film 12 Angry Men. This movie may be used in training settings focused on helping relationships to reflect upon the meaning of being an individual in a group, being a group, responsibility and choice. A key to the reading of the movie is proposed at two different but complementary levels. From an “extra-psychical” standpoint, movie characters may represent a working group of 12 very different people sharing a task, while from an “intra-psychical” one, each character may represent an embodiment or symbol of an individual’s part and/or complex. According to the movie suggestion, we describe a path from objectiveness to subjectiveness and the final accomplishment of an ethical choice.

    This study was undertaken to examine the effects of 12 weeks of skeletal unloading on parameters of calcium homeostasis, calcitropic hormones, bone histology, and biochemical markers of bone turnover in 11 normal subjects (9 men, 2 women; 34 +/- 11 years of age). Following an ambulatory control evaluation, all subjects underwent 12 weeks of bed rest. An additional metabolic evaluation was performed after 12 days of reambulation. Bone mineral density declined at the spine (-2.9%, p = 0.092) and at the hip (-3.8%, p = 0.002 for the trochanter). Bed rest prompted a rapid, sustained, significant increase in urinary calcium and phosphorus as well as a significant increase in serum calcium. Urinary calcium increased from a pre-bed rest value of 5.3 mmol/day to values as high as 73 mmol/day during bed rest. Immunoreactive parathyroid hormone and serum 1,25-dihydroxyvitamin D declined significantly during bed rest, although the mean values remained within normal limits. Significant changes in bone histology included a suppression of osteoblastic surface for cancellous bone (3.1 +/- 1.3% to 1.9 +/- 1.5%, p = 0.0142) and increased bone resorption for both cancellous and cortical bone. Cortical eroded surface increased from 3.5 +/- 1.1% to 7.3 +/- 4.0% (p = 0.018) as did active osteoclastic surface (0.2 +/- 0.3% to 0.7 +/- 0.7%, p = 0.021). Cancellous eroded surface increased from 2.1 +/- 1.1% to 4.7 +/- 2.2% (p = 0.002), while mean active osteoclastic surface doubled (0.2 +/- 0.2% to 0.4 +/- 0.3%, p = 0.020). Serum biochemical markers of bone formation (osteocalcin, bone-specific alkaline phosphatase, and type I procollagen extension peptide) did not change significantly during bed rest. Urinary biochemical markers of bone resorption (hydroxyproline, deoxypyridinoline, and N-telopeptide of type I collagen) as well as a serum marker of bone resorption (type I collagen carboxytelopeptide) all demonstrated significant increases during bed rest which declined toward normal

    We report on a patient after knee reconstruction for osteosarcoma in the distal femur using a hingeless prosthesis K-MAX KNEE system K-5 who walked without ipsilateral knee extension in the latter half of the stance phase (flexed knee gait). We evaluated the patient using three-dimensional gait analysis and isokinetic knee strength measurement, and compared the patient with five healthy subjects. The Musculoskeletal Tumor Society (MSTS) score was also used for evaluation. The patient kept his operated knee flexed during mid stance. The maximal ankle plantarflexion internal moment was lower on the ipsilateral side than on the contralateral side, and lower than in the healthy subjects. The negative ankle power during the stance phase was generally stronger on the ipsilateral side than on the contralateral side, and also in the healthy subjects. Unusual contralateral hip flexion occurred after the initial contact, indicating increased joint load on the ipsilateral ankle and the contralateral hip. The ratios of the peak knee extension/flexion torque were 0.7 on the ipsilateral side, 1.9 on the contralateral side, and 1.7 in the healthy subjects. The MSTS score of the patient was 23/30 (76.6%). Flexed knee gait might account for the reduction of ipsilateral hip flexion and ankle plantarflexion moment during the late stance phase. These results suggest the importance of focusing more on the ipsilateral ankle joint and the contralateral hip joint to maintain the function of the entire limb joints of the patients with flexed knee gait.

    This paper outlines twelve tips for undertaking peer observation of teaching in medical education, using the peer review model and the experiences of the authors. An accurate understanding of teaching effectiveness is required by individuals, medical schools, and universities to evaluate the learning environment and to substantiate academic and institutional performance. Peer Observation of Teaching is one tool that provides rich, qualitative evidence for teachers, quite different from closed-ended student evaluations. When Peer Observation of Teaching is incorporated into university practice and culture, and is conducted in a mutually respectful and supportive way, it has the potential to facilitate reflective change and growth for teachers.

    2002-01-01

    Full Text Available Genetic progress depends on germplasm quality and breeding methods. Twelve maize populations and their crosses were evaluated to estimate combining ability and potential to be included as source populations in breeding programs. Plant height, point of insertion of the first ear, number of ears per plant, number of grains per ear, root and stalk lodging and grain yield were studied in two locations in Brazil, during the 1997/98 season. Genotype sum of squares was divided into general (GCA and specific (SCA combining ability. Results indicated the existence of genetic divergence for all traits analyzed, where additive effects were predominant. The high heterosis levels observed, mainly in Xanxerê, suggested the environmental influence on the manifestation of this genetic phenomenon. Populations revealed potential to be used in breeding programs; however, those more intensively submitted to selection could provide larger genetic progress, showing the importance of population improvement for the increment of the heterosis in maize.

  14. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

    Full Text Available Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and Pacific oceans and in the Caribbean and Mediterranean seas. Brazilian sponges remain understudied concerning antifouling activities. Only two scientific articles reported this activity in sponges of Brazil. The objective of this study was to test crude extracts of twelve species of sponges from Brazil against the attachment of the mussel Perna perna through laboratorial assays, and highlight promising species for future studies. The species Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra, and Tethya maza were frozen and freeze-dried before extraction with acetone or dichloromethane. The crude extract of four species significantly inhibited the attachment of byssus: Tethya rubra (p = 0.0009, Tethya maza (p = 0.0039, Petromica citrina (p = 0.0277, and Hymeniacidon heliophila (p = 0.00003. These species, specially, should be the target of future studies to detail the substances involved in the ability antifouling well as to define its amplitude of action.

    Wood elastic constants are needed to describe the elastic behaviors of wood and be taken as an important design parameter for wood-based composite materials and structural materials. This paper clarified the relationships between compliance coefficients and engineering elastic constants combined with orthotropic properties of wood, and twelve elastic constants of Betula platyphylla Suk. were measured by electrical strain gauges. Spreading the adhesive quantity cannot be excessive or too little when the strain flakes were glued. If excessive, the glue layer was too thick which would influence the strain flakes' performance, and if too little, glues plastered were not firm, which could not accurately transmit the strain. Wood as an orthotropic material, its modulus of elasticity and poisson's ratios are related by two formulas:μij /Ei =μji /Ej and μij 0.95) between the reciprocal of elastic modulus MOE-1 and the square of the ratio of depth to length (h/l)2, which indicate that shear modulus values measured were reliable by three point bending experiment.

    Full Text Available Pigmented villonodular synovitis (PVNS is a rare, benign, but a locally aggressive tumor. It is characterized by the proliferation of synovial membrane, but it can also be seen in tendon sheaths and bursae. Clinical presentation of solitary lesions include compression and locking of the joint suggesting loose bodies in the joint and a subsequent findings of an effusion, whereas diffuse lesions manifest with pain and chronic swelling. In this article, we presented a curious case of PVNS in a female patient who have been followed up due to an acetabular cystic lesion. She underwent total hip arthroplasty for severe osteoarthritis of the hip joint and associated pain. The diagnosis of PVNS was established intraoperatively.

    OBJECTIVE Hepatic angiosarcoma (HAS), a lethal disease, is the most common sarcoma arising in the liver. Little information about the epidemiology, etiology, diagnosis and management of HAS has been reported. Increased familiarity with this disease will facilitate correct diagnosis and help to improve management of this condition in the future.The objective of this study was to describe cases of hepatic angiosarcoma and to discuss the etiologic, diagnostic, therapeutic features and prognosis of this tumor. This report not only serves to give more evidence of the relationship between hepatic angiosarcoma and carcinogenic exposure, but also demonstrates the key points in different methods of diagnosis and the optimal treatment of hepatic angiosarcoma.METHODS Twelve cases of hepatic angiosareoma were analyzed retrospectively, representing the different character in clinical presentations and laboratory computed tomographical scans; pathological data and treatment are described. Clinical and biologic follow-up was carried out for two years after surgical treatment.RESULTS There were nine men and three women varying in ages from 57 to 71 years with an average of 64.3 years. Ten patientshad a history of exposure to vinyl chloride or thorotrast. Mild or moderate abdominal pain and bloating, abdominal mass and fever were the common clinical presentations. Tumors were visualized by ultrasonography and CT scans in all patients. Biochemical profiles yielded variable results and proved to be of little value in detection or diagnosis. Surgical resection was feasible for each patient who was treated as follows: two wedge resections, six segementectomies and four bisegmentectomies. Five patients received Neoadjuvant chemotherapy postoperatively. The survival rate of those cases was poor. The maximum survival time was fourteen months. The mean survival time for this chemotherapeutic group was 11 months. The difference between the survival time of those treated with an operation

    Coronary Artery Disease (CAD) risk increases with increasing number of risk factors. This study was aimed to assess different coronary risk factors among Coronary Artery Bypass Grafting (CABG) surgery patients. A total of 700 patients younger than 45 or older than 65 years and underwent CABG in Tabriz Shahid Madani Heart Center since 2003 to 2007 were enrolled. We examined the probable differences of CAD risk factors between male and female groups and age groups. We also assessed the change of risk factors presentation in last 5 years. There was not significant difference between risk factor numbers in 65 years groups, but smoking and dyslipidemia was more prevalent in patients 65 years old. Hypertension and diabetes mellitus was more prevalent in patients > 65 old than < 45 years old; also differences were found between males and females patients, so that dyslipidemia, diabetes and hypertension were more prevalent in women than men. Some risk factors were recognized as acting more on one gender than the other. Also, the majority of patients have one or more risk factors, but different age and gender groups may have different risk factors that suggest the need for exact programming for appropriate prophylactic and therapeutic interventions in all groups.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

  3. The twelve dimensional super (2+2)-brane

    CERN Document Server

    Hewson, S F

    1996-01-01

    We discuss supersymmetry in twelve dimensions and present a covariant supersymmetric action for a brane with worldsheet signature (2,2), called a super (2+2)-brane, propagating in the osp(64,12) superspace. This superspace is explicitly constructed, and is trivial in the sense that the spinorial part is a trivial bundle over spacetime, unlike the twisted superspace of usual Poincare supersymmetry. For consistency, it is necessary to take a projection of the superspace. This is the same as the projection required for worldvolume supersymmetry. Upon compactification of this superspace, a torsion is naturally introduced and we produce the membrane and type IIB string actions in 11 and 10 dimensional Minkowski spacetimes. In addition, the compactification of the twelve dimensional supersymmetry algebra produces the correct algebras for these theories, including central charges. These considerations thus give the type IIB string and M-theory a single twelve dimensional origin.

Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

    Marcos George de Souza Leão

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

  12. The twelve theses: a call to a new reformation

    Full Text Available With every discovery emerging from the world of science over the last 500 years concerning the origins of the universe and of life itself, the traditional explanations offered by the Christian Church appeared to be more and more dated and irrelevant.  Christian leaders, unable to embrace the knowledge revolution seemed to believe  that the only way to save Christianity was not to disturb the old patterns either by listening to, much less by entertaining the new knowledge. I tried to articulate this challenge in a book entitled: Why Christianity Must Change or Die, published in 1998.  In that book I examined in detail the issues that I was convinced Christianity must address. Shortly after that book was published I reduced its content to twelve theses, which I attached in Luther-like fashion to the great doors on the Chapel of Mansfield College at Oxford University in the United Kingdom. I then mailed copies of those Twelve Theses to every acknowledged Christian leader of the world. It was an attempt to call them into a debate on the real issues that I was certain the Christian Church now faced.  I framed my twelve theses in the boldest, most provocative language possible, designed primarily to elicit response and debate. I welcome responses from Christians everywhere.  I claim no expertise or certainty in developing answers, but I am quite confident that I do understand the problems we are facing as Christians who are seeking to relate to the 21st century.

    Body weight loss is a common outcome in patients with gastric cancer who have undergone gastrectomy. However, the rate of body weight loss after surgery is unknown. In this retrospective study, we selected patients who underwent radical gastrectomy for gastric cancer and were diagnosed with Stage II or III disease. Further, we compared the body weight loss after surgery between patients in the surgery alone group and the S-1 adjuvant chemotherapy group. We evaluated 163 patients, of which 81 underwent only surgery, and 82 underwent surgery followed up with S-1 adjuvant chemotherapy. The body weight loss rate at 1, 3, and 6 months in the surgery alone group were 93.1%, 92.9%, and 94.9%, while those in the S-1 adjuvant group were 92.9%, 90.4%,and 91.9%, which was a significant difference. Body weight loss after gastrectomy was higher in the S-1 adjuvant group than in the surgery alone group. Further, nutritional support is required for these patients to maintain body weight after surgery.

    2017-07-01

    Dyslexia is a common learning difficulty. As a result of SS' own experiences as a medical student with dyslexia, we have been researching and teaching on this topic for the past two years. Here, we present twelve tips for teaching medical students with dyslexia. These are gathered from our personal experiences and research, discussions with other educators, and wider literature on the topic. This article aims to shed some light on dyslexia, and also to make practical suggestions. Teaching students with dyslexia should not be a daunting experience. Small changes to existing methods, at minor effort, can make a difference - for example, adding pastel colors to slide backgrounds or avoiding Serif fonts. These tips can help educators gain more insight into dyslexia and incorporate small, beneficial adaptations into their teaching.

    Full Text Available Members of the genus Centaurea (Asteraceae have been used in traditional plant-based medicine. The methanol extracts of twelve Centaurea species, of which five are endemic to Turkey flora, were screened for antibacterial activity against four bacteria (Escherichia coli, Bacillus cereus, Salmonella enteritidis, Staphylococcus aureus. The antibacterial activity was evaluated by the microdilution method and the minimum inhibition concentrations (MIC of the extracts were determined. C. cariensis subsp. microlepis exhibited an antimicrobial effect on all tested microorganisms. The extracts from eight Centaurea species (C. balsamita, C. calolepis, C. cariensis subsp. maculiceps, C. cariensis subsp. microlepis, C. kotschyi var. kotschyi, C. solstitialis subsp. solstitialis, C. urvillei subsp. urvillei and C. virgata possessed antibacterial activity against several of the tested microorganisms.

    2017-09-17

    Medical education is an expanding area of specialist interest for medical professionals. Whilst most doctors will be familiar with the compilation of clinical portfolios for scrutiny of their clinical practice and provision of public accountability, teaching portfolios used specifically to gather and demonstrate medical education activity remain uncommon in many non-academic settings. For aspiring and early career medical educators in particular, their value should not be underestimated. Such a medical educator's portfolio (MEP) is a unique compendium of evidence that is invaluable for appraisal, revalidation, and promotion. It can stimulate and provide direction for professional development, and is a rich source for personal reflection and learning. We recommend that all new and aspiring medical educators prepare an MEP, and suggest twelve tips on how to skillfully compile one.

    We present spectra of twelve Type Ia supernovae obtained in 1999 at the William Herschel Telescope and the Nordic Optical Telescope during a search for Type Ia supernovae (SN Ia) at intermediate redshift. The spectra range from z=0.178 to z=0.493, including five high signal-to-noise ratio SN Ia spectra in the still largely unexplored range 0.15 < z < 0.3. Most of the spectra were obtained before or around restframe B-band maximum light. None of them shows the peculiar spectral features found in low-redshift over- or under-luminous SN Ia. Expansion velocities of characteristic spectral absorption features such as SiII at 6355 angs., SII at 5640 angs. and CaII at 3945 angs. are found consistent with their low-z SN Ia counterparts.

    Ataxia telangiectasia (A-T) is an autosomal recessive disease characterized mainly by progressive cerebellar ataxia, oculocutaneous telangiectasia, and immunodeficiency. This disease is caused by mutations of the ataxia telangiectasia mutated (Atm) gene. More than 500 Atm mutations that are responsible for A-T have been identified so far. However, there have been very few A-T cases reported in China, and only two Chinese A-T patients have undergone Atm gene analysis. In order to systemically investigate A-T in China and map their Atm mutation spectrum, we recruited eight Chinese A-T patients from six unrelated families nationwide. Using direct sequencing of genomic DNA and the multiplex ligation-dependent probe amplification, we identified twelve pathogenic Atm mutations, including one missense, four nonsense, five frameshift, one splicing, and one large genomic deletion. All the Atm mutations we identified were novel, and no homozygous mutation and founder-effect mutation were found. These results suggest that Atm mutations in Chinese populations are diverse and distinct largely from those in other ethnic areas.

    Papillary squamous cell carcinoma (PSCC) is a distinct histological subtype of oral squamous cell carcinoma (SCC), described in both dogs and man. In dogs, PSCC has long been considered a malignant oral tumour of very young animals, but it has recently been reported to occur in adult dogs as well. The aim of this study was to describe the major clinicopathological characteristics of canine oral PSCC (COPSCC). Twelve dogs diagnosed with COPSCC were included in this retrospective study (1990-2012). The majority (75%) of the dogs were >6 years of age (median age 9 years). All tumours were derived from the gingiva of dentate jaws, with 66.7% affecting the rostral aspects of the jaws. The gross appearance of the lesions varied, with one having an intraosseous component only. The majority (91.7%) of the tumours were advanced lesions (T2 and T3), but no local or distant metastases were noted. Microscopically, two patterns were seen: (1) invasion of bone forming a cup-shaped indentation in the bone or a deeply cavitating cyst within the bone (cavitating pattern), (2) histologically malignant growth, but lack of apparent bone invasion (non-cavitating pattern). The microscopical appearance corresponded to imaging findings in a majority of cases, with cavitating forms presenting with a cyst-like pattern of bone loss or an expansile mass on imaging and non-cavitating forms showing an infiltrative pattern of bone destruction on imaging. These features suggest two distinct biological behaviours of COPSCC.

    Twelve cultivars of Elatior begonia (Begonia X hiemalis Fotsch.) were exposed to O/sub 3/ at 25 and 50 pphM. The 'Schwabenland' group, 'Whisper 'O' Pink', and 'Improved Krefeld Orange' were the most sensitive, whereas 'Ballerina', 'Mikkell Limelight', and 'Turo' were the least sensitive. 'Rennaisance', 'Heirloom' 'Nixe', and 'Fantasy' were intermediate in sensitivity. The dry weight of foliage (stems plus leaves) of 9 cultivars exposed to O/sub 3/ was significantly less than that of control plants. Ozone at 25 and 50 pphM inhibited flower growth (including peduncles) and development in 4 and 8 of the 12 cultivars, respectively. Differences in flower weight ranged from 43 to 105% of the control at 25 pphM and from 25 to 98% of the control at 50 pphM, depending on cultivar. 1 table.

    Longitudinal integrated clerkships (LICs) involve learners spending an extended time in a clinical setting (or a variety of interlinked clinical settings) where their clinical learning opportunities are interwoven through continuities of patient contact and care, continuities of assessment and supervision, and continuities of clinical and cultural learning. Our twelve tips are grounded in the lived experiences of designing, implementing, maintaining, and evaluating LICs, and in the extant literature on LICs. We consider: general issues (anticipated benefits and challenges associated with starting and running an LIC); logistical issues (how long each longitudinal experience should last, where it will take place, the number of learners who can be accommodated); and integration issues (how the LIC interfaces with the rest of the program, and the need for evaluation that aligns with the dynamics of the LIC model). Although this paper is primarily aimed at those who are considering setting up an LIC in their own institutions or who are already running an LIC we also offer our recommendations as a reflection on the broader dynamics of medical education and on the priorities and issues we all face in designing and running educational programs.

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies.

  6. The strong coupling regime of twelve flavors QCD

    We summarize the results recently reported in Ref.[1] [A. Deuzeman, M.P. Lombardo, T. Nunes da Silva and E. Pallante,"The bulk transition of QCD with twelve flavors and the role of improvement"] for the SU(3) gauge theory with Nf=12 fundamental flavors, and we add some numerical evidence and theoretical discussion. In particular, we study the nature of the bulk transition that separates a chirally broken phase at strong coupling from a chirally restored phase at weak coupling. When a non-improved action is used, a rapid crossover is observed at small bare quark masses. Our results confirm a first order nature for this transition, in agreement with previous results we obtained using an improved action. As shown in Ref.[1], when improvement of the action is used, the transition is preceded by a second rapid crossover at weaker coupling and an exotic phase emerges, where chiral symmetry is not yet broken. This can be explained [1] by the non hermiticity of the improved lattice Transfer matrix, arising from the c...

    Recent work shows that increased meal frequency reduces ghrelin responses in sheep. Human research suggests there is an interaction between insulin and ghrelin. The effect of meal frequency on this interaction is unknown. Therefore, we investigated the effect of feeding frequency on insulin...... and ghrelin responses in human subjects. Five healthy male volunteers were recruited from the general population: age 24 (SEM 2)years, body mass 75.7 (SEM 3.2) kg and BMI 23.8 (SEM 0.8) kg/m(2). Volunteers underwent three 8-h feeding regimens: fasting (FAST); low-frequency(two) meal ingestion (LOFREQ(MEAL......)); high-frequency (twelve) meal ingestion (HIFREQ(MEAL)). Meals were equi-energetic within trials,consisting of 64% carbohydrate, 23% fat and 13% protein. Total energy intake was equal between feeding trials. Total area under the curve for serum insulin and plasma ghrelin responses did not differ between...

  8. Comparative analysis and supragenome modeling of twelve Moraxella catarrhalis clinical isolates

    Full Text Available Abstract Background M. catarrhalis is a gram-negative, gamma-proteobacterium and an opportunistic human pathogen associated with otitis media (OM and exacerbations of chronic obstructive pulmonary disease (COPD. With direct and indirect costs for treating these conditions annually exceeding $33 billion in the United States alone, and nearly ubiquitous resistance to beta-lactam antibiotics among M. catarrhalis clinical isolates, a greater understanding of this pathogen's genome and its variability among isolates is needed. Results The genomic sequences of ten geographically and phenotypically diverse clinical isolates of M. catarrhalis were determined and analyzed together with two publicly available genomes. These twelve genomes were subjected to detailed comparative and predictive analyses aimed at characterizing the supragenome and understanding the metabolic and pathogenic potential of this species. A total of 2383 gene clusters were identified, of which 1755 are core with the remaining 628 clusters unevenly distributed among the twelve isolates. These findings are consistent with the distributed genome hypothesis (DGH, which posits that the species genome possesses a far greater number of genes than any single isolate. Multiple and pair-wise whole genome alignments highlight limited chromosomal re-arrangement. Conclusions M. catarrhalis gene content and chromosomal organization data, although supportive of the DGH, show modest overall genic diversity. These findings are in stark contrast with the reported heterogeneity of the species as a whole, as wells as to other bacterial pathogens mediating OM and COPD, providing important insight into M. catarrhalis pathogenesis that will aid in the development of novel therapeutic regimens.

In in vitro MTT assay, 1–12 inhibited human cancer K562, HL-60 and HeLa cells with inhibition rates ranging from 64.2% to 92.9% at 100 μg/mL, and their IC50 values were determined to be varied in 17.2–124.7 μM on the tested three human cancer cell lines. In addition, compounds 1–12 inhibited murine sarcoma S180 cells with inhibition rates ranging from 38.7% to 52.8% at 100 μg/mL in the in vitro MTT assay, and in vivo antitumor activity of 1 and 2 was also detected in murine sarcoma S180 tumor-bearing Kunming mice using taxol as positive control.

    The Brazzaville cancer registry was created in 1996 with the support of the International Agency Research against Cancer (IARC) which is located in Lyon, France. The Brazzaville cancer registry is a registry which is based on population which records new cancer cases occurring in Brazzaville by using Canreg 4.0 Software. Its aim is to supply useful information to fight against cancer to physicians and to decision makers. We conducted this study whose target was to determine the incidence of cancer in Brazzaville during twelve years, from January 1st, 1998 to December 31, 2009. During that period 6,048 new cancer cases were recorded: 3,377 women (55.8%), 2,384 men (39.4%), and 287 children (4.8%) from 0 to 14 years old with an annual average of 504 cases. Middle age to the patient's diagnosis was 49.5 years in female sex and 505.5 years old for male sex. The incidence rate of cancers in Brazzaville was 39.8 or 100.000 inhabitants per year and by sex we observed 49 to female sex and 35.2 for male sex. The first cancers localizations observed to women were in order of frequency: breast, cervix uterine, liver ovaries, hematopoietic system, to men : liver, prostate, hematopoietic system, colon and stomach; to children : retina, kidney, hematopoietic system, liver and bones. These rates are the basis to know the burden of cancer among all pathologies of Brazzaville and the achievement of a national cancer control program.

    2001-09-01

    Hyperinsulinism and hyperammonemia syndrome has been reported as a cause of moderately severe hyperinsulinism with diffuse involvement of the pancreas. The disorder is caused by gain of function mutations in the GLUD1 gene, resulting in a decreased inhibitory effect of guanosine triphosphate on the glutamate dehydrogenase (GDH) enzyme. Twelve unrelated patients (six males, six females) with hyperinsulinism and hyperammonemia syndrome have been investigated. The phenotypes were clinically heterogeneous, with neonatal and infancy-onset hypoglycemia and variable responsiveness to medical (diazoxide) and dietary (leucine-restricted diet) treatment. Hyperammonemia (90-200 micromol/L, normal carbamylglutamate administration. The patients had mean basal GDH activity (18.3 +/- 0.9 nmol/min/mg protein) not different from controls (17.9 +/- 1.8 nmol/min/mg protein) in cultured lymphoblasts. The sensitivity of GDH activity to inhibition by guanosine triphosphate was reduced in all patient lymphoblast cultures (IC(50), or concentrations required for 50% inhibition of GDH activity, ranging from 140 to 580 nM, compared with control IC(50) value of 83 +/- 1.0 nmol/L). The allosteric effect of ADP was within the normal range. The activating effect of leucine on GDH activity varied among the patients, with a significant decrease of sensitivity that was correlated with the negative clinical response to a leucine-restricted diet in plasma glucose levels in four patients. Molecular studies were performed in 11 patients. Heterozygous mutations were localized in the antenna region (four patients in exon 11, two patients in exon 12) as well as in the guanosine triphosphate binding site (two patients in exon 6, two patients in exon 7) of the GLUD1 gene. No mutation has been found in one patient after sequencing the exons 5-13 of the gene.

    Full Text Available Abstract Background Pulmonary rehabilitation programs have been shown to increase functional exercise capacity and quality of life in COPD patients. However, following the completion of pulmonary rehabilitation the benefits begin to decline unless the program is of longer duration or ongoing maintenance exercise is followed. Therefore, the aim of this study is to determine if supervised, weekly, hospital-based exercise compared to home exercise will maintain the benefits gained from an eight-week pulmonary rehabilitation program in COPD subjects to twelve months. Methods Following completion of an eight-week pulmonary rehabilitation program, COPD subjects will be recruited and randomised (using concealed allocation in numbered envelopes into either the maintenance exercise group (supervised, weekly, hospital-based exercise or the control group (unsupervised home exercise and followed for twelve months. Measurements will be taken at baseline (post an eight-week pulmonary rehabilitation program, three, six and twelve months. The exercise measurements will include two six-minute walk tests, two incremental shuttle walk tests, and two endurance shuttle walk tests. Oxygen saturation, heart rate and dyspnoea will be monitored during all these tests. Quality of life will be measured using the St George's Respiratory Questionnaire and the Hospital Anxiety and Depression Scale. Participants will be excluded if they require supplemental oxygen or have neurological or musculoskeletal co-morbidities that will prevent them from exercising independently. Discussion Pulmonary rehabilitation plays an important part in the management of COPD and the results from this study will help determine if supervised, weekly, hospital-based exercise can successfully maintain functional exercise capacity and quality of life following an eight-week pulmonary rehabilitation program in COPD subjects in Australia.

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    To analyse whether mitochondrial DNA (mtDNA) haplogroups are associated with severe sepsis and mortality after major surgery. We performed a case-control study on 240 cardiac or abdominal surgery patients developing severe sepsis (Case-group) and 267 cardiac or abdominal surgery patients without severe sepsis and with systemic inflammatory response syndrome (SIRS, Control-group). Furthermore, a longitudinal substudy was performed for analysing the survival in septic patients. Only European white patients within the N macro-cluster were included. Case-group underwent cardiac surgery had lower frequencies of cluster HV (p = 0.005) and haplogroup H (p = 0.005) and higher frequencies of cluster JT (p = 0.028) than Control-group; but no significant differences were found for abdominal surgery. Besides, both cluster HV and haplogroup H were associated with decreased odds of severe sepsis (adjusted odds ratio (aOR) = 0.45 (95%CI = 0.25; 0.82); p = 0.009 and aOR = 0.48 (95%CI = 0.26; 0.87); p = 0.015, respectively) among patients underwent cardiac surgery. In Case-group, 45.4% (109/240) patients died with a survival median of 39 (95%CI = 31.4; 46.62) days. When the clusters were examined, 41% (55/134) patients within cluster HV died versus 71.4% (10/14) patients within cluster IWX (p = 0.018). Additionally, patients within cluster IWX had an increased risk of death (adjusted hazard ratio (aHR) = 2.22; (95%CI = 1.14; 4.34); p = 0.019). European mitochondrial haplogroups might be related to the onset of severe sepsis in patients who underwent major cardiac surgery, but not in patients underwent major abdominal surgery. Besides, mtDNA haplogroups could have influence on mortality in septic patients. Copyright © 2014 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Background and aims: Dysphagic patients who underwent endoscopic gastrostomy (PEG usually present protein-energy malnutrition, but little is known about micronutrient malnutrition. The aim of the present study was the evaluation of serum zinc in patients who underwent endoscopic gastrostomy and its relationship with serum proteins, whole blood zinc, and the nature of underlying disorder. Methods: From patients that underwent gastrostomy a blood sample was obtained minutes before the procedure. Serum and whole blood zinc was evaluated using Wavelength Dispersive X-ray Fluorescence Spectroscopy. Serum albumin and transferrin were evaluated. Patients were studied as a whole and divided into two groups: head and neck cancer (HNC and neurological dysphagia (ND. Results: The study involved 32 patients (22 males, aged 43-88 years: HNC = 15, ND = 17. Most (30/32 had low serum zinc, 17/32 presented normal values of whole blood zinc. Only two, with traumatic brain injury, presented normal serum zinc. Serum zinc levels showed no differences between HNC and ND patients. There was no association between serum zinc and serum albumin or transferrin. There was no association between serum and whole blood zinc. Conclusions: Patients had low serum zinc when gastrostomy was performed, similar in HNC and ND, being related with prolonged fasting and unrelated with the underlying disease. Decrease serum zinc was unrelated with low serum proteins. Serum zinc was more sensitive than whole blood zinc for identifying reduced zinc intake. Teams taking care of PEG-patients should include zinc evaluation as part of the nutritional assessment, or include systematic dietary zinc supply.

    Full Text Available Aim: The aim of the study was is to assess the incidence of unexpected gynecological cancers and pre-cancerous lesions following hysterectomy for pelvic organ prolapse to better understand the risks of uterine sparing surgery. Material and Method: This was a retrospective analysis of histopathology findings after hysterectomy for uterine prolapse surgery who underwent preoperative diagnostic work including cervical cytology, transvaginal ultrasonography and endometrial histopathological examination for a high risk group (Postmenopausal women with an endometrial thickness of %u22655 mm and premenopausal women with abnormal bleeding. Patients with a history of endometrial, cervical and/or adnexal precancerous or cancerous pathological conditions and with incomplete medical records were excluded.Results: Results were taken from 106 women who underwent hysterectomy. The abdominal route was used in 22 cases (21.7 %, the vaginal route in 82 patients (77.4 % and laparoscopic-assisted vaginal route in two (1.9 % women. Oophorectomy was performed in 35 (33 % cases. None of the patients had malignant histopathology specimens from hysterectomy. Total premalignant pathology incidence was 7.5 % (8/106. Six (5.7% patients had simple endometrial hyperplasia and 2 patients (1.9 % had cervical intraepithelial neoplasia. Discussion: The incidence of unexpected endometrial, cervical or ovarian malignancy among women who underwent hysterectomy after preoperative diagnostic workup including transvaginal ultrasonograhy, endometrial pathological examination to high risk cases was negligible. The inclusion of low risk endometrial and cervical precancerous lesions increased the incidences. Our results could provide precious data to extrapolate to similar populations with uterine prolapse who desire surgical correction sparing uterus.

    Particle concentration measurements with underwing probes on aircraft are impacted by air compression upstream of the instrument body as a function of flight velocity. In particular, for fast-flying aircraft the necessity arises to account for compression of the air sample volume. Hence, a correction procedure is needed to invert measured particle number concentrations to ambient conditions that is commonly applicable to different instruments to gain comparable results. In the compression region where the detection of particles occurs (i.e. under factual measurement conditions), pressure and temperature of the air sample are increased compared to ambient (undisturbed) conditions in certain distance away from the aircraft. Conventional procedures for scaling the measured number densities to ambient conditions presume that the air volume probed per time interval is determined by the aircraft speed (true air speed, TAS). However, particle imaging instruments equipped with pitot tubes measuring the probe air speed (PAS) of each underwing probe reveal PAS values systematically below those of the TAS. We conclude that the deviation between PAS and TAS is mainly caused by the compression of the probed air sample. From measurements during two missions in 2014 with the German Gulfstream G-550 (HALO - High Altitude LOng range) research aircraft we develop a procedure to correct the measured particle concentration to ambient conditions using a thermodynamic approach. With the provided equation, the corresponding concentration correction factor ξ is applicable to the high-frequency measurements of the underwing probes, each of which is equipped with its own air speed sensor (e.g. a pitot tube). ξ values of 1 to 0.85 are calculated for air speeds (i.e. TAS) between 60 and 250 m s-1. For different instruments at individual wing position the calculated ξ values exhibit strong consistency, which allows for a parameterisation of ξ as a function of TAS for the current HALO

    Sjogren's syndrome is one of the most common autoimmune disorders and has a female predominance. Maternal circulating autoantibodies such as anti-Ro/SSA and anti-La/SSB antibodies can cause congenital heart block of fetus, and in severe case, emergency pacemaker implantation may be needed for neonate. Therefore, it is very important to understand maternal and fetal condition and pay attention to the status of the neonate during delivery. In this paper, we present a case of patient with Sjogren's syndrome who underwent cesarean section under spinal anesthesia. PMID:27274376

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    Objective:To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy.Methods:A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0), 30 min during operation (T1), and 12 h after operation (T2) were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05). HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05). PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05).Conclusions:Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    The present study aimed to establish the profile of patients who underwent orthognathic surgery in a private clinic by evaluating their demographic characteristics, their facial types, and aspects related to the surgical procedures that were performed. The sample consisted of 419 medical records from male and female patients aged 15 to 62 years who underwent orthognathic surgery between 2001 and 2011. A single examiner collected data by evaluating a database of information extracted from medical records, particularly radiographic and photographic analyses. The following criteria were evaluated: gender, age, skin color, type of orthognathic surgery, type of associated temporomandibular joint (TMJ) surgery, complications, and recurrences. Seventeen patients were rejected because they had incomplete records. The average age of the patients was 28.5 years old; most were females (255 patients) and faioderm (295 patients). The most prevalent facial pattern was Pattern III (n = 166, 41.3%). Orthognathic surgery that affected the maxilla, jaw, and chin was the most prevalent type (n = 199, 49.5% of cases). A genioplasty was performed concurrently with combined surgeries and single-jaw surgery in 76.86% of patients (n = 309). TMJ surgery was performed concomitantly with orthognathic surgery in 4% of cases (n = 16). The most common postoperative complication was infection/inflammation (n = 12). We concluded that there was a higher frequency of orthognathic surgery among women and young people, the brunette skin phenotype was prevalent, and most patients had a combination of maxillary and mandibular problems.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Full Text Available PURPOSE: The aim of our study is to evaluate the undergrading and understaging rates in patients with clinically localized insignificant prostate cancer who underwent radical prostatectomy. MATERIALS AND METHODS: Between July 2005 and July 2008, 406 patients underwent radical prostatectomy for clinical localized prostate cancer in our hospital. Based on preoperative data, 93 of these patients fulfilled our criteria of non-significance: Gleason score < 7, stage T1c, PSA < 10 ng/mL and percentage of affected fragments less than 25%. The pathologic stage and Gleason score were compared to preoperative data to evaluate the rate of understaging and undergrading. The biochemical recurrence free survival of these operated insignificant cancers were also evaluated. RESULTS: On surgical specimen analysis 74.7% of patients had Gleason score of 6 or less and 25.3% had Gleason 7 or greater. Furthermore 8.3% of cases showed extracapsular extension. After 36 months of follow-up 3.4% had biochemical recurrence, defined by a PSA above 0.4 ng/mL. CONCLUSIONS: Despite the limited number of cases, we have found considerable rates of undergrading and understaging in patients with prostate cancer whose current definitions classified them as candidates for active surveillance. According to our results the current definition seems inadequate as up to a third of patients had higher grade or cancer outside the prostate.

    Full Text Available OBJECTIVE: Evaluate and correlate the functional response of patients with cervical myelopathy with the current clinical scores in patients who underwent surgical treatment. METHODS: We analyzed medical records of 34 patients with cervical myelopathy who underwent four different types of surgery. All patients were evaluated preoperatively and postoperatively with the application of the JOA and Nurick questionnaires. RESULTS: Functional clinical improvement was statistically significant. The mean preoperative JOA was 8.5 ± 3.06 and 10.7 ± 3.9 in the postoperative; Nurick was 3.2 ± 1.1 preoperatively and 2.8 ± 1.3 postoperatively. CONCLUSION: There is benefit with the surgical procedure in patients with cervical myelopathy. The neurological function after surgery depends on the previous function (the higher the duration of the previous symptoms, the greater the progression of the disease and, therefore, worse the neurological function and the age is not a relevant factor of improvement, as already shown in other series. The clinical functional improvement of patients is visible with surgical treatment, regardless of surgical technique.

    Full Text Available Introduction: Emergency department thoracotomy (EDT may serve as the last survival chance for patients who arrive at hospital in extremis. It is considered as an effective tool for improvement of traumatic patients’ outcome. The present study was done with the goal of assessing the outcome of patients who underwent EDT and its predictive factors. Methods: In the present study, medical charts of 50 retrospective and 8 prospective cases underwent emergency department thoracotomy (EDT were reviewed during November 2011 to June 2013. Comparisons between survived and died patients were performed by Mann-Whitney U test and the predictive factors of EDT outcome were measured using multivariate logistic regression analysis. P < 0.05 considered statistically significant. Results: Fifty eight cases of EDT were enrolled (86.2% male. The mean age of patients was 43.27±19.85 years with the range of 18-85. The mean time duration of CPR was recorded as 37.12±12.49 minutes. Eleven cases (19% were alive to be transported to OR (defined as ED survived. The mean time of survival in ED survived patients was 223.5±450.8 hours. More than 24 hours survival rate (late survived was 6.9% (4 cases. Only one case (1.7% survived to discharge from hospital (mortality rate=98.3%. There were only a significant relation between ED survival and SBP, GCS, CPR duration, and chest trauma (p=0.04. The results demonstrated that initial SBP lower than 80 mmHg (OR=1.03, 95% CI: 1.001-1.05, p=0.04 and presence of chest trauma (OR=2.6, 95% CI: 1.75-3.16, p=0.02 were independent predictive factors of EDT mortality. Conclusion: The findings of the present study showed that the survival rate of trauma patients underwent EDT was 1.7%. In addition, it was defined that falling systolic blood pressure below 80 mmHg and blunt trauma of chest are independent factors that along with poor outcome.

    To investigate the incidence rate and the risk factors for postoperative cognitive dysfunction (POCD) in patients underwent coronary artery bypass grafting surgery. A total of 147 patients underwent elective coronary artery bypass grafting (CABG) surgery between January to July 2013 were included in this study. POCD was diagnosed using a neuropsychological test battery. All enrolled patients were interviewed on the day before surgery, the seventh day and 3 months after surgery, respectively, by the same researcher, and were divided into two groups based on the results: the POCD group and the non-POCD group. The information, including age, sex, body mass index, educational status, comorbidities, history of smoking and drinking, ASA grade, left ventricular ejection fraction, operation method, duration of operations, regional cerebral oxygen saturation, the lowest haemoglobin concentrations and the haemoglobin concentration decline rate during the operation, tracheal catheter retention time, postoperative pain on visual analogue scales (VAS) and systemic inflammatory response syndrome score (SIRS score), were recorded based on a schedule of survey. Multivariate logistic regression was used to analyze the risk factors for POCD. A total of 101 patients finished this study. On 7 days and 3 months after surgery, 38 and 21 cases showed POCD, with an incidence rate at 37.6% and 20.8%, respectively. Interestingly, there was no significant difference in incidence of POCD between CABG and OPCABG group on both 7 days and 3 months after surgery (P>0.05). The logistic stepwise regression analysis indicated that the risk factors for POCD included advanced age (OR=1.177, 95%CI 1.071-1.292, P=0.001), the haemoglobin concentration decline rate (OR=1.334, 95%CI 1.152-1.545, PSIRS score (OR=2.815, 95%CI 1.014-7.818, P=0.047). The incidence rate of POCD was 37.6% and 20.8% on 7 days and 3 months after surgery respectively. Advanced age, the haemoglobin concentration decline rate and

    The effects which quantum fields and an $R^2$ term in the gravitational Lagrangian have on future singularities are investigated in the case that the universe underwent Starobinsky inflation in the past. The dark energy is modeled as a perfect fluid, and the focus is on type I-IV singularities and little rips which result when the classical Einstein equations are solved with various types of dark energy as a source. First, evidence is provided that the energy densities of massive conformally coupled scalar fields approach that of the conformally invariant scalar field as a type III singularity is approached. Then, solutions to the semiclassical backreaction equations are investigated when conformally invariant fields and an $R^2$ term in the gravitational Lagrangian are present. General proofs regarding the behaviors of the solutions in cases where the dark energy results in classical singularities of the above types are given. These indicate that backreaction effects always make little rips, where the scale ...

    Meralgia paresthetica is commonly caused by a focal entrapment of lateral femoral cuteneous nerve while it passes the inguinal ligament. Common symptoms are paresthesias and numbness of the upper lateral thigh area. Pregnancy, tight cloths, obesity, position of surgery and the tumor in the retroperitoneal space could be causes of meralgia paresthetica. A 29-year-old female patient underwent an emergency cesarean section under spinal anesthesia without any problems. But two days after surgery, the patient complained numbness and paresthesia in anterolateral thigh area. Various neurological examinations and L-spine MRI images were all normal, but the symptoms persisted for a few days. Then, electromyogram and nerve conduction velocity test of the trunk and both legs were performed. Test results showed left lateral cutaneous nerve injury and meralgia paresthetica was diagnosed. Conservative treatment was implemented and the patient was free of symptoms after 1 month follow-up.

    A 42-year-old female with EDTA-dependent pseudothrombocytopenia underwent emergent clipping surgery for a ruptured aneurysm. On admission, the platelet count was low, but bleeding time and coagulation test were within normal limits. The blood smear anticoagulated with EDTA revealed remarkable agglutination of platelets, while heparinized blood showed a normal level. Diagnosis of EDTA-dependent pseudothrombocytopenia was made. The progressive drop in platelet count occurred within 10 minutes in the presence of EDTA. The autocounter misjudged the agglutination of platelets as red or white blood cells. The earlier study reported the incidence of this diseases as 0.07%. This disease is often misdiagnosed. Therefore, thrombocytopenia without any clinical symptom should be considered as showing a possible symptom of EDTA-dependent pseudothrombocytopenia.

    Abstract Adjuvant transarterial chemoembolization (TACE) is a major option for postoperative hepatocellular carcinoma (HCC) patients with recurrence risk factors. However, individualized predictive models for subgroup of these patients are limited. This study aimed to develop a prognostic nomogram for patients with HCC underwent adjuvant TACE following curative resection. A cohort comprising 144 HCC patients who received adjuvant TACE following curative resection in the Zhongshan Hospital were analyzed. The nomogram was formulated based on independent prognostic indicators for overall survival (OS). The performance of the nomogram was evaluated by the concordance index (C-index), calibration curve, and decision curve analysis (DCA) and compared with the conventional staging systems. The results were validated in an independent cohort of 86 patients with the same inclusion criteria. Serum alpha-fetoprotein (AFP), hyper-sensitive C-reactive protein (hs-CRP), incomplete tumor encapsulation, and double positive staining of Cytokeratin 7 and Cytokeratin 19 on tumor cells were identified as independent predictors for OS. The C-indices of the nomogram for OS prediction in the training cohort and validation cohort were 0.787 (95%CI 0.775–0.799) and 0.714 (95%CI 0.695–0.733), respectively. In both the training and validation cohorts, the calibration plot showed good consistency between the nomogram-predicted and the observed survival. Furthermore, the established nomogram was superior to the conventional staging systems in terms of C-index and clinical net benefit on DCA. The proposed nomogram provided an accurate prediction on risk stratification for HCC patients underwent adjuvant TACE following curative resection. PMID:28296727

    Full Text Available Objective: Adnexal masses are the most common reason for gynecologic surgery in adolescent patients. Early detection and adequate management of adnexal lesions are very important for saving lives and preserving fertility. In this study, we analyzed the clinical characteristics of 106 Turkish adolescent women who underwent surgery for adnexal masses. Methods: The study included 106 patients aged ≤20 years that underwent surgery for adnexal masses at our hospital between January 2008 and December 2013. Clinical profiles were retrospectively collected from the hospital medical records. The records were analyzed for demographic profiles, initial symptoms, preoperative radiologic findings, operative approach, surgical procedure, pathology findings, and the maximum diameter of the adnexal mass. Results: The age of the patients ranged from 12 to 20 years (median, 18.8 years. The most common initial symptom in these patients was abdominal pain (56.6%. Non-neoplastic ovarian lesions in the patients included 7 (6.6% corpora hemorrhagica, 10 (9.4% corpus luteal cysts, 4 (3.8% paratubal cysts, and 7 (6.6% simple cysts. Benign neoplastic tumors included 20 (18.9% mature cystic teratomas (i.e., dermoid tumors, 10 (9.4% serous cystadenomas, 1 (0.9% mucinous cystadenomas, and 7 (6.6% endometriomas. The most common surgical approach and procedure were laparoscopy (67.0% and cystectomy (60.4%, respectively. Conclusion: Laparoscopy can be performed in many adolescent patients and conservative, adnexal-sparing surgery should be encouraged for all patients. Ovarian-preserving techniques should be a priority when surgery is performed for benign masses in order to optimize future fertility potential. J Clin Exp Invest 2015; 6 (2: 96-101

    The objectives of this retrospective study were to elucidate the clinicopathological features and recent surgical results of cervical esophageal cancer. Cervical esophageal cancer has been reported to have a dismal prognosis. Accurate knowledge of the clinical characteristics of cervical esophageal cancer is warranted to establish appropriate therapeutic strategies. The clinicopathological features and treatment results of 63 consecutive patients with cervical esophageal cancer (Ce group) who underwent surgical resection from 1980 to 2013 were analyzed and compared with 977 patients with thoracic or abdominal esophageal cancer (T/A group) who underwent surgical resection during that time. Among the patients who received curative resection, the 5-year overall and disease-specific survival rates of the Ce patients were significantly better than those of the T/A patients (overall: 77.3% vs 46.5%, respectively, P = 0.0067; disease-specific: 81.9% vs 55.8%, respectively, P = 0.0135). Although total pharyngo-laryngo-esophagectomy procedures were less frequently performed in the recent period, the rate of curative surgical procedures was markedly higher in the recent period (2000-1013) than that in the early period (1980-1999) (44.4% vs 88.9%, P = 0.0001). The 5-year overall survival rate in the recent period (71.5%) was significantly better than that in the early period (40.7%, P = 0.0342). Curative resection for cervical esophageal cancer contributes to favorable outcomes compared with other esophageal cancers. Recent surgical results for cervical esophageal cancer have improved, and include an increased rate of curative resection and decreased rate of extensive surgery.

    Patients suffering from long standing dysphagia need tube feeding through gastrostomy. Nutritional assessment of these patients is challenging and must be supported on objective data, including anthropometric evaluation. The aim of this study was the evaluation of the usefulness of anthropometry for identifying and grading malnutrition, as part of the initial assessment of patients that underwent endoscopic gastrostomy. From the files of consecutive adults underwent gastrostomy we selected patients with anthropometric data obtained before the procedure: Body Mass Index, Mid Upper Arm Circumference, Triceps Skinfold Thickness and Mid Arm Muscle Circumference. Nutritional status was classified according with World Health Organization criteria for Body Mass Index, and for Mid Upper Arm Circumference, Triceps Skinfold Thickness and Mid Arm Muscle Circumference using comparison with Frisancho reference-tables. Were selected 367 patients (median of ages: 74.1 years): neurological disease: 172; head and neck cancer: 176; other diseases: 19. Body Mass Index identified 136 underweight and 231 eutrophic or overweight patients. Mid Upper Arm Circumference identified 310 malnourished and 57 eutrophic or overweight patients. Triceps Skinfold Thickness identified 301 malnourished and 66 eutrophic or overweight patients. Mid Arm Muscle Circumference identified 269 malnourished, 97 eutrophic and one with MAMC above normal. Anthropometry identified the malnourished endoscopic gastrostomy-patients, contributed for malnutrition grading and demonstrated the impact on muscle and fat reserves. Mid Upper Arm Circumference, Triceps Skinfold Thickness and Mid Arm Muscle Circumference identified malnutrition in nearly 80% of the patients, most clearly with fat tissue wasting than muscle. Easily accessible e inexpensive, anthropometry allowed personalized nutritional therapy. Anthropometry must be recognized as a fundamental tool for enteral feeding teams.

    Full Text Available The role of decompressive craniectomy in the treatment of severe posttraumatic cerebral swelling remains quite a controversial issue. To the best of our knowledge, there is no study demonstrating the effect of decompressive craniectomy on cerebral blood flow (CBF velocity by means of transcranial Doppler sonography (TCD. We present two patients who developed traumatic brain swelling and uncontrollable intracranial hypertension with coma and signs of transtentorial herniation. One patient underwent bifrontal, while the second, unilateral, frontotemporoparietal decompressive craniectomy with dural expansion. In both patients, TCD examinations were performed immediately before and after surgery to study the cerebral hemodynamic changes related to the operations. Pre and postoperative TCD examinations demonstrated a significant increase in blood flow velocity in the intracranial arteries in both subjects. In conclusion, our cases suggest that decompressive craniectomy with dural expansion may result in elevation of CBF velocity in patients with massive brain swelling. The increase in CBF velocity appears to occur not only in the decompressed hemisphere, but also on the opposite side.

    Retaining lectures in problem-based learning (PBL) curriculum places new demands on lecturers. In addition to subject knowledge, the lecturers must know the overall aims of the lectures, their context in the course, their relation to the subsequent examinations and the underlying educational philosophy. Aim of this communication is to propose ways that will transform the traditional didactic lectures into PBL-compliant teaching/learning sessions. Insights from the self-experience and that of colleagues and the feedback from students are synthesised with current literature regarding best teaching practices to develop these tips. These tips, ranging from involving students in the learning process to a routine practice of reflection after delivering a lecture, highlight methods of preparing and delivering lectures that follow the educational philosophy underpinning the PBL approach. We believe that these tips by advancing the driving force for meaningful learning will transform the didactic lectures of traditional curriculum to interactive sessions that would enhance understanding, augment critical thinking and promote self-directed learning among students.

    Disruption of microcirculation in various tissues as a result of deformed blood rheology due to ventricular assist device (VAD) implantation causes novel arteriovenous malformations. Capillary disturbances and related vascular leakage in the retina and choroidea may also be seen in patients supported by VADs. We aimed to evaluate retinal vasculature deteriorations after VAD implantation. The charts of 17 patients who underwent VAD implantation surgery for the treatment of end-stage heart failure were retrospectively reviewed. Eight cases (47.1%) underwent pulsatile pump implantation (Berlin Heart EXCOR, Berlin Heart Mediprodukt GmbH, Berlin, Germany); however, nine cases (52.9%) had continuous-flow pump using centrifugal design (HeartWare, HeartWare Inc., Miramar, FL, USA). Study participants were selected among the patients who had survived with a VAD for at least 6 months, and results of detailed ophthalmologic examinations including optic coherence tomography (OCT) and fundus fluorescein angiography (FA) were documented. All of the 17 patients were male, with a mean age of 48.5 ± 14.8 years (15-67 years). Detailed ophthalmologic examinations including the evaluation of retinal vascular deteriorations via FA were performed at a mean of 11.8 ± 3.7 months of follow-up (6-18 months). Mean best-corrected visual acuity and intraocular pressure were found as logMAR 0.02 ± 0.08 and 14.6 ± 1.9 mm Hg, respectively in the study population. Dilated fundoscopy revealed severe focal arteriolar narrowing in two patients (11.8%), and arteriovenous crossing changes in four patients (23.5%); however, no pathological alteration was present in macular OCT scans. In patients with continuous-flow blood pumps, mean arm-retina circulation time (ARCT) and arteriovenous transit time (AVTT) were found to be 16.8 ± 3.0 and 12.4 ± 6.2 s, respectively; whereas those with pulsatile-flow blood pumps were found to be 17.4 ± 3.6 and 14.0 ± 2.1 s in patients (P=0.526 and P=0

    Fifty-eight patients (mean age 18.4 years) who had received splint therapy for internal derangement of the temporomandibular joint (TMJ) were examined retrospectively to investigate the efficacy of occlusal reconstruction by orthodontic treatment. The subjects were divided into three groups: 18 patients (mean age 18.6 years) who underwent orthodontic treatment combined with the use of splints (ST group); 27 patients (mean age 18.2 years) who underwent orthodontic treatment without the use of splints (NST group); and 13 patients (mean age 17.9 years) who received only splint therapy for temporomandibular joint disorders (TMD; control group). TMJ sound, pain on movement and restriction of mandibular movement were examined at the initial examination (T1), at the end of the splint therapy for TMD or beginning of orthodontic treatment (T2), at the end of orthodontic treatment (T3), and at recall or 1 year after orthodontic treatment (T4). The following results were found. (1) The percentage of patients with no joint sound at T2 was 20-30 per cent. The percentage of such patients in both the ST and NST groups increased to over 50 per cent at T3, but slightly decreased to 39-50 per cent at T4. There were no significant inter-group differences at any time point. (2) The number of patients who had no pain on movement at T2 was 60-80 per cent. The percentage of such patients in both the ST and NST groups increased to over 90 per cent at T3, but then slightly decreased to 80 per cent at T4. There were no significant inter-group differences at any time point. (3) None of the patients showed restriction of movement of the TMJ at T2 or T4. One patient in the ST group was found to have restriction at T3. There were no significant inter-group differences at any time point. (4) The most frequent type of malocclusion in both ST and NST groups was anterior open bite. These results suggest that TMD symptoms that have been eliminated by splint therapy are not likely to recur due to

    For normal eyes without history of any ocular surgery, traditional equations for calculating intraocular lens (IOL) power, such as SRK-T, Holladay, Higis, SRK-II, et al., all were relativley accurate. However, for eyes underwent refractive surgeries, such as LASIK, or eyes diagnosed as keratoconus, these equations may cause significant postoperative refractive error, which may cause poor satisfaction after cataract surgery. Although some methods have been carried out to solve this problem, such as Hagis-L equation[1], or using preoperative data (data before LASIK) to estimate K value[2], no precise equations were available for these eyes. Here, we introduced a novel intraocular lens power estimation method by accurate ray tracing with optical design software ZEMAX. Instead of using traditional regression formula, we adopted the exact measured corneal elevation distribution, central corneal thickness, anterior chamber depth, axial length, and estimated effective lens plane as the input parameters. The calculation of intraocular lens power for a patient with keratoconus and another LASIK postoperative patient met very well with their visual capacity after cataract surgery.

    Full Text Available Background. Hypothermia in the surgical patients can be the consequence of long duration of surgical intervention, general anesthesia and low temperature in operating room. Postoperative hypothermia contributes to a number of postoperative complications such as arrhythmia, myocardial ischemia, hypertension, bleeding, wound infection, coagulopathy, prolonged effect of muscle relaxants. External heating procedures are used to prevent this condition, but some investigations reported that infusion of aminoacids during surgery can induce thermogenesis and prevent postoperative hypothermia. Case report. We reported two males who underwent major colorectal surgery for rectal carcinoma. One patient received Aminosol 15% solution, 125 ml/h, while the other did not. The esophageal temperatures in both cases were measured every 30 minutes during the operation and 60 minutes after in Intensive Care Unit. We were monitoring blood pressure, heart rate, ECG, and shivering. Patient who received aminoacids showed ameliorated postoperative hypothermia without hypertension, arrhythmia, or shivering, while the other showed all symptoms mentioned above. Conclusion. According to literature data, as well as our findings, we can conclude that intraoperative intravenous treatment with amino acid solution ameliorates postoperative hypothermia along with its complications. .

    OBJECTIVE To evaluate the incidence of residual thyroid cancer and cervical lymph node metastasis following a previous local resection for thyroid cancer, and to discuss methods of a reoperation.METHODS From 1994~2005, 118 patients with thyroid cancer who had previously been treated with a nodule-resection or subtotal Iobectomy in other hospitals underwent a surgical re-operation.RESULTS The incidence of residual cancer at the primary site was 38.1%. The lymph node metastasis rate at the central area was 39.8%.The rate of lymph node metastasis in patients with enlarged lymph nodes in the ipsilateral internal jugular chain was 37.5%. The rate of laryngeal recurrent nerve injury was 15.2% in other hospitals while that of the second operation in our hospital was 1.6%.CONCLUSION Nodule-resection or subtotal Iobectomy alone is not indicated for patients with thyroid cancer because of the high rate of local residual cancer. It is important to be familiar with the anatomy of the laryngeal recurrent nerve for thyroid surgery. Exploration to the central area is necessary for differentiated thyroid cancer.

Two groups of patient were analyzed, one using vancomycin on the surgical site, vancomycin group (VG and the control group (CG without topical vancomycin. The routine prophylactic procedures were performed in both groups: aseptic scrub technique, skin preparation, preoperative intravenous antibiotic therapy. The VG received a dose of 1g of vancomycin mixed with the bone graft every three spinal levels fused and the group consisted of 232 patients.Results:513 patients were analyzed, 232 in the VG and 281 in the CG. There was no statistical difference between the groups when the sex, mean surgery length, and mean bleeding volume were considered. The rate of infection for VG was reduced from 4.98% to 1.29% when compared with CG.Conclusion:The use of vancomycin added to the bone graft in posterior spinal fusion is associated with significantly lower rates of infection.

    PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients’ responses were graded according to the Miller–Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR (P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens (P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.

    Full Text Available Background: Venous thromboembolism (VTE is a fatal yet potentially preventable complication of surgery. Routine thromboprophylaxis is still unequivocal prescription is problematic due to perception of low VTE incidence among Asian population. This study aims to investigate the incidence of VTE and thromboprophylaxis prescription among patients undergoing major surgery in a Singapore hospital.Methods: This was a cross-sectional study. Data were obtained from medical record of 1,103 patients who had underwent major orthopaedic or abdominal surgery in 2011-2012 at Khoo Teck Puat Hospital, Singapore. Incidence of VTE events either in the same admission or re-admission in less than one month time were noted as study parameters.Results: Incidence of VTE was 2.1% (95% CI: 1.67 - 2.53 of which 1.3% and 0.8% were DVT and PE cases respectively. Age, gender, history of VTE, ischemic heart disease, and mechanical prophylaxis were associated with VTE incidence based on bivariate analysis. The prescription of pharmacological thromboprophylaxis was associated with prior anticoagulant medication, type of surgery, and incidence of new bleeding. Conclusion: Subsequent to major surgeries, VTE is as common in Asian patients as published data in other populations. Pharmacologic thromboprophylaxis should be considered as recommended in non-Asian guidelines.Keywords: thromboprophylaxis, venous thromboembolism

    Basal and squamous cell carcinomas are the most common malignant cutaneous lesions affecting the nose. With the rising incidence of skin cancers, plastic surgeons increasingly face nasal reconstruction challenges. Although multiple options exist, optimal results are obtained when "like is used to repair like". We aimed to introduce a simple algorithm for the reconstruction of nasal defects with local flaps, realizing that there is always more than one option for reconstruction. We retrospectively reviewed 163 patients who underwent nasal reconstruction after excision of non-melanoma skin cancer between March 2011 and April 2014. We analyzed the location of the defects and correlated them with the techniques used to reconstruct them. There were 66 males and 97 females (age, 21-98 years). Basal cell carcinoma was diagnosed in 121 patients and squamous cell carcinoma in 42. After tumor excision, all the defects were immediately closed by either primary closure or local flap options such as Limberg, Miter, glabellar, bilobed, nasolabial, V-Y advancement, and forehead flaps. Obtaining tumor-free borders and a pleasing aesthetic result are major concerns in nasal reconstruction. Defect reconstruction and cosmesis are as important as rapid recovery and quick return to normal daily activities, and these should be considered before performing any procedure, particularly in elderly patients.

    The objective of this double-blind clinical study, conducted in harmony with American Dental Association guidelines, was to compare a new dentifrice formulation variant of Colgate Total Toothpaste containing a special grade of silica (Colgate Total Plus Whitening Toothpaste) to the commercially available, ADA-Accepted and clinically proven Colgate Total Toothpaste for controlling breath odor twelve hours after brushing the teeth. Breath odor was evaluated by a panel of three examiners using a nine-point hedonic scale. Following a baseline evaluation of breath odor, prospective study subjects who scored above the threshold value for unpleasant breath odor were stratified by score and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints or mounthrinses for the next twelve hours, after which they were again evaluated for breath odor. Eighty-three (83) adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study. At twelve hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. Importantly, there was no statistical difference between the two dentifrices of the mean twelve-hour breath odor scores. The mean twelve-hour breath scores for the Colgate Total Plus Whitening Toothpaste group and the Colgate Total Toothpaste group were 4.89 and 4.67, respectively, which are within the range of values corresponding to pleasant breath odor. Thus, the results of this double-blind clinical study, conducted according to a protocol which had been approved by the Council on Scientific Affairs of the American Dental Association, support the conclusion that Colgate Total Plus Whitening Toothpaste and Colgate

    The effects of resistance training on arterial blood pressure and muscle sympathetic nerve activity (MSNA) at rest have not been established. Although endurance training is commonly recommended to lower arterial blood pressure, it is not known whether similar adaptations occur with resistance training. Therefore, we tested the hypothesis that whole body resistance training reduces arterial blood pressure at rest, with concomitant reductions in MSNA. Twelve young [21 +/- 0.3 (SE) yr] subjects underwent a program of whole body resistance training 3 days/wk for 8 wk. Resting arterial blood pressure (n = 12; automated sphygmomanometer) and MSNA (n = 8; peroneal nerve microneurography) were measured during a 5-min period of supine rest before and after exercise training. Thirteen additional young (21 +/- 0.8 yr) subjects served as controls. Resistance training significantly increased one-repetition maximum values in all trained muscle groups (P training did not affect MSNA or heart rate. Arterial blood pressures and MSNA were unchanged, but heart rate increased after 8 wk of relative inactivity for subjects in the control group (61 +/- 2 to 67 +/- 3 beats/min; P = 0.01). These results indicate that whole body resistance exercise training might decrease the risk for development of cardiovascular disease by lowering arterial blood pressure but that reductions of pressure are not coupled to resistance exercise-induced decreases of sympathetic tone.

    Full Text Available Background: People vary greatly in their response to painful stimuli, from those with a low pain threshold to those with indifference to pain. However, insensitivity to pain is a rare disorder, characterized by the lack of usual subjective and objective responses to noxious stimuli. Patients who have congenital indifference to pain sustain painless injuries beginning in infancy, but have sensory responses that are otherwise normal on examination. Perception of passive movement, joint position, and vibration is normal in these patients, as are tactile thresholds and light touch perception. Case report: A twelve-year-old boy was admitted to the hospital for a painless deformity, degeneration in both knees and a neglected femoral neck fracture that was inappropriately painless. Further examination revealed normal sensory responses, perception of passive movement, joint position, vibration tactile thresholds and light touch perception. Spinal cord and brain MRI were normal as was the electromyography and nerve conduction velocity (EMG/NCV examination. There was no positive family history for this disorder. Conclusion: The deficits present in the different pain insensitivity syndromes provide insight into the complex anatomical and physiological nature of pain perception. Reports on pain asymbolia, in which pain is perceived but does not cause suffering, and related cortical conditions illustrate that there can be losses that independently involve either the sensory-discriminative component or the affective-motivational component of pain perception, thus highlighting their different anatomical localization. The paucity of experience with this entity and the resultant diagnostic problems, the severity of the associated disabling arthropathy and underscore the importance of this case report of indifference to pain.

    Patients that underwent Percutaneous Endoscopic Gastrostomy (PEG) present with protein-energy malnutrition. Trace elements are required in small quantities and Chromium (Cr) displays a major role in the metabolism. This study aims to evaluate Cr levels and its relationship with serum proteins, BMI and underlying diseases during the first 3 months of PEG feeding. Prospective observational study during 3-months, when PEG was performed (T0), after 4 (T1), and 12 weeks (T3). Initial evaluation included: age, gender, underlying disease, NRS-2002, BMI, serum albumin, transferrin and Cr concentration. At T1 and T3 a blood sample was collected for Cr, albumin and transferrin. A Graphite Furnace Atomic Absorption Spectroscopy was used to assess Cr. According with the underlying disease, patients were divided into two groups: head and neck cancer (HNC) and neurological dysphagia (ND). All patients were fed with homemade meals. A one hundred and twenty-nine patients (80 males), 26-95 years old were studied: HNC-52; ND-77. The observed data included low mean values of BMI from 71 patients; low Cr-8, low albumin-70, low transferrin-85 and 57 with both proteins low. Albumin was associated with survival time ( P =0.024) and there was a significant correlation between albumin and Cr (r=0.217, P =0.012). A good evolution of Cr and proteins values was observed, with no low Cr levels at T3. Low serum Cr is rare in PEG-patients, with no relationship to other studied parameters. For the minority of patients displaying low Cr before gastrostomy, homemade PEG meals seem to be effective.

    endoscopic gastrostomy (PEG) patients usually present protein-energy malnutrition, but little is known about selenium deficiency. We aimed to assess serum selenium evolution when patients underwent PEG, after 4 and 12 weeks. We also evaluated the evolution of albumin, transferrin and Body Mass Index and the influence of the nature of the underlying disease. a blood sample was obtained before PEG (T0), after 4 (T1) and 12 (T3) weeks. Selenium was assayed using GFAAS (Furnace Atomic Absorption Spectroscopy). The PEG patients were fed through homemade meals. Patients were studied as a whole and divided into two groups: head and neck cancer (HNC) and neurological dysphagia (ND). we assessed 146 patients (89 males), between 21-95 years old: HNC-56; ND-90. Normal values of selenium in 79% (n=115); low albumin in 77, low transferrin in 94, low values for both serum proteins in 66. Low BMI in 78. Selenium has slow evolution, with most patients still displaying normal Selenium at T3 (82%). Serum protein levels increase from T0 to T3, most patients reaching normal values. The nature of the underlying disease is associated with serum proteins but not with selenium. low serum selenium is uncommon when PEG is performed, after 4 and 12 weeks of enteral feeding and cannot be related with serum proteins levels or dysphagia cause. Enteral nutrition using customized homemade kitchen meals is satisfactory to prevent or correct Selenium deficiency in the majority of PEG patients. Copyright AULA MEDICA EDICIONES 2014.

    Full Text Available The relationship between a perioperative change in sarcopenic status and clinical outcome of liver transplantation (LT is unknown. We investigated whether post-LT sarcopenia and changes in sarcopenic status were associated with the survival of patients.This retrospective study was based on a cohort of 145 patients from a single transplant center who during a mean of 1 year after LT underwent computed tomography imaging evaluation. The cross-sectional area of the psoas muscle of LT patients was compared with that of age- and sex-matched healthy individuals. The Cox proportional hazards regression model was used to determine whether post-LT sarcopenia and changes in sarcopenic status affect post-LT survival.The mean age at LT of the 116 male and 29 female patients was 50.2 ± 7.9 years; the mean follow-up duration was 51.6 ± 32.9 months. All pre-LT patients with sarcopenia still had sarcopenia 1 year after LT; 14 (15% patients had newly developed sarcopenia. The mean survival duration was 91.8 ± 4.2 months for non-sarcopenic patients and 80.0 ± 5.2 months for sarcopenic patients (log-rank test, p = 0.069. In subgroup analysis, newly developed sarcopenia was an independent negative predictor for post-LT survival (hazard ratio: 10.53, 95% confidence interval: 1.37-80.93, p = 0.024.Sarcopenia in LT recipients did not improve in any of the previously sarcopenic patients and newly developed within 1 year in others. Newly developed sarcopenia was associated with increased mortality. Newly developed sarcopenia can be used to stratify patients with regard to the risk of post-LT mortality.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    Otilonium bromide (OB) is a spasmolytic drug successfully used for the treatment of irritable bowel syndrome (IBS). Its efficacy has been attributed to the block of L- and T-type Ca(2+) channels and muscarinic and tachykinin receptors in the smooth muscle. Furthermore, in healthy rats, repeated OB administration modified neurotransmitter expression and function suggesting other mechanisms of action. On this basis, we investigated whether repeated OB treatment prevented the functional and neurochemical changes observed in the colon of rats underwent to wrap restrain stress (WRS) a psychosocial stressor considered suitable to reproduce the main IBS signs and symptoms. In control, WRS and OB/WRS rats functional parameters were measured in vivo and morphological investigations were done ex vivo in the colon. The results showed that OB counteracts most of the neurotransmitters changes caused by WRS. In particular, the drug prevents the decrease in SP-, NK1r-, nNOS-, VIP-, and S100β-immunoreactivity (IR) and the increase in CGRP-, and CRF1r-IR. On the contrary, OB does not affect the increase in CRF2r-IR neurons observed in WRS rats and does not interfere with the mild mucosal inflammation due to WRS. Finally, OB per se increases the Mr2 expression in the muscle wall and decreases the number of the myenteric ChAT-IR neurons. Functional findings show a significantly reduction in the number of spontaneous abdominal contraction in OB treated rats. The ability of OB to block L-type Ca(2+) channels, also expressed by enteric neurons, might represent a possible mechanism through which OB exerts its actions. © 2016 The Authors.

    The reproductive ground plan hypothesis (RGPH) proposes that the physiological pathways regulating reproduction were co-opted to regulate worker division of labor. Support for this hypothesis in honeybees is provided by studies demonstrating that the reproductive potential of workers, assessed by the levels of vitellogenin (Vg), is linked to task performance. Interestingly, contrary to honeybees that have a single Vg ortholog and potentially fertile nurses, the genome of the harvester ant Pogonomyrmex barbatus harbors two Vg genes (Pb_Vg1 and Pb_Vg2) and nurses produce infertile trophic eggs. P. barbatus, thus, provides a unique model to investigate whether Vg duplication in ants was followed by subfunctionalization to acquire reproductive and non-reproductive functions and whether Vg reproductive function was co-opted to regulate behavior in sterile workers. To investigate these questions, we compared the expression patterns of P. barbatus Vg genes and analyzed the phylogenetic relationships and molecular evolution of Vg genes in ants. qRT-PCRs revealed that Pb_Vg1 is more highly expressed in queens compared to workers and in nurses compared to foragers. By contrast, the level of expression of Pb_Vg2 was higher in foragers than in nurses and queens. Phylogenetic analyses show that a first duplication of the ancestral Vg gene occurred after the divergence between the poneroid and formicoid clades and subsequent duplications occurred in the lineages leading to Solenopsis invicta, Linepithema humile and Acromyrmex echinatior. The initial duplication resulted in two Vg gene subfamilies preferentially expressed in queens and nurses (subfamily A) or in foraging workers (subfamily B). Finally, molecular evolution analyses show that the subfamily A experienced positive selection, while the subfamily B showed overall relaxation of purifying selection. Our results suggest that in P. barbatus the Vg gene underwent subfunctionalization after duplication to acquire caste- and

    Full Text Available Abstract Background Protease inhibitors are known to alter the lipid profiles in subjects treated for HIV/AIDS. However, the magnitude of this effect on plasma lipoproteins and lipids has not been adequately quantified. Objective To estimate the changes in plasma lipoproteins and triglycerides occurring within 12 months of initiating PI-based antiretroviral therapy among HIV/AIDS afflicted subjects. Methods We included all antiretroviral naïve HIV-infected persons treated at St-Paul's Hospital, British Columbia, Canada, who initiated therapy with protease inhibitor antiretroviral (ARV drugs between August 1996 and January 2002 and who had at least one plasma lipid measurement. Longitudinal associations between medication use and plasma lipids were estimated using mixed effects models that accounted for repeated measures on the same subjects and were adjusted for age, sex, time dependent CD4+ T-cell count, and time dependent cumulative use of non-nucleoside reverse transcriptase inhibitors and adherence. The cumulative number of prescriptions filled for PIs was considered time dependent. We estimated the changes in the 12 months following any initiation of a PI based regimen. Results A total of 679 eligible subjects were dispensed nucleoside analogues and PI at the initiation of therapy. Over a median 47 months of follow-up (interquartile range (IQR: 29–62, subjects had a median of 3 (IQR: 1–6 blood lipid measurements. Twelve months after treatment initiation of PI use, there was an estimated 20% (95% confidence interval: 17% – 24% increase in total cholesterol and 22% (12% – 33% increase in triglycerides. Conclusions Twelve months after treatment initiation with PIs, statistically significant increases in total cholesterol and triglycerides levels were observed in HIV-infected patients under conditions of standard treatment. Our results contribute to the growing body of evidence implicating PIs in the development of blood lipid

    To evaluate the risk of missing a malignancy in surgical specimens following hysterectomy for uterine prolapse if routine pathological examination is not performed. Additionally, information on the risk of missing an hitherto unsuspected malignancy if uterine preservation is the preferred management option will be provided. A retrospective study was performed on all cases of surgery performed for uterine prolapse in a tertiary referral institution from 2003 to 2011. Those with confirmed malignancy before operation were excluded. The study subjects had their clinical history, investigations, the type of operations and histopathology report analysed. They were classified into symptomatic or asymptomatic, depending on whether they reported symptoms that were suggestive of uterine malignancy. A total of 640 women were studied. Three cases of hitherto unsuspected uterine malignancy were found, giving an incidence of 0.47%. Among the 456 asymptomatic women, both pre- and postmenopausal, the risk of incidental malignancy was 0.22%. Within the postmenopausal group, risk of incidental malignancy was 0.26%. Another 3 cases of uterine premalignant conditions were identified, giving an overall risk of premalignant and malignant uterine condition of 0.94%. Five cases of cervical intra-epithelial neoplasia were found, contributing to a risk of 0.78%. The risk of missing an uterine malignancy in patients with uterine prolapse is low if appropriate investigations are carried out prior to surgery. If hysterectomy is to be performed, we recommend that all surgical specimens be subjected to histopathological examination. © 2013 The Authors ANZJOG © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Objectives: the aim of this study was to identify the feelings and opinions of the women about the experience lived in the pre-partum and humanized childbirth at Santa Lucinda's Hospital, based on the humanization of preconized assistance by the Ministry of Health. Methods: it treats of a descriptive and qualitative research. Fifteen puerperas who participated of the humanized childbirth at Santa Lucinda's Hospital, reported of the Basic Health Unit Sorocaba I of Sorocaba county, had participated in the study. It was used the Coletive Subject Discourse technique and the theory referential of Minayo, where the instrument of work was a recorded interview with two orientation questions. Results and Discussion: in the analysis, the talks were combined in eleven central ideas. The importance of the humanized assistance was emphasized and related to feelings of calmness and strength, as well as the pain was directly related to negative feelings and expressions such as fear, preoccupation and hate but followed by the feeling of compensation where the first contact with the baby becomes exciting and can be summarized in relief and joy. About the no pharmacological methods of pain relief and the accompanying's right, which are importance points to the childbirth humanization, it predominates the positive opinions. Conclusion: it can be concluded that it is necessary to reflect about the experience of humanized childbirth considering the individuality of each woman, for the applicability of it by the team be effective, providing an integral assistance to the women, respecting the middle which she is inserted.

    The aim of this retrospective study was to evaluate the accuracy of bone SPECT (single photon emission computed tomography)/CT (computed tomography) in diagnosing loosening of fixation material in patients with recurrent or persistent back pain that underwent lumbar arthrodesis with pedicle screws using surgery and clinical follow-up as gold standard A total of 48 patients (median age 49 years, range 21-81 years; 17 men) who had undergone lumbar spinal arthrodesis were included in this retrospective analysis. SPECT/CT results were compared to the gold standard of surgical evaluation or clinical follow-up. Positive SPECT/CT results were considered true positives if findings were confirmed by surgery or if clinical and other examinations were completely consistent with the positive SPECT/CT finding. They were considered false positives if surgical evaluation did not find any loose pedicle screws or if symptoms subsided with non-surgical therapy. Negative SPECT/CT scans were considered true negatives if symptoms either improved without surgical intervention or remained stable over a minimum follow-up period of 6 months. Negative SPECT/CT scans were determined to be false negatives if surgery was still required and loosening of material was found. The median length of time from primary surgery to bone SPECT/CT referral was 29.5 months (range 12-192 months). Median follow-up was 18 months (range 6-57) for subjects who did not undergo surgery. Thirteen of the 48 patients were found to be positive for loosening on bone SPECT/CT. Surgical evaluation (8 patients) and clinical follow-up (5 patients) showed that bone SPECT/CT correctly predicted loosening in 9 of 13 patients, while it falsely diagnosed loosening in 4 patients. Of 35 negative bone SPECT/CT scans, 12 were surgically confirmed. In 18 patients, bone SPECT/CT revealed lesions that could provide an alternative explanation for the symptoms of pain (active facet degeneration in 14 patients, and disc and sacroiliac

    Increased sympathetic nervous system (SNS) activity has been associated with stress, major depression, aging, and several medical conditions. This study assessed the effect of the selective serotonin reuptake inhibitor (SSRI), sertraline, on sympathetic nervous system (SNS) activity in healthy subjects. Twelve healthy volunteers participated in a double-blind, placebo-controlled, norepinephrine (NE) kinetic study, in which the effects of sertraline on SNS activity were ascertained by determining NE plasma concentrations and NE plasma appearance rates and clearance rates in sertraline or placebo conditions. Subjects received 50 mg of sertraline or placebo for two days and then one week later underwent the same protocol with the other drug. By single compartmental analysis, plasma NE appearance rates were significantly lower in the sertraline compared to the placebo condition (0.26+/-0.10 vs 0.40+/-0.23 microg/m(2)/min; P=0.04). Our study found that the net effect of short-term SSRI treatment is an apparent suppression of SNS activity as indicated by a decreased plasma NE appearance rate in the sertraline condition. If this preliminary finding can be extended to long-term treatment of patients, this could have significant therapeutic relevance for treating depression in elderly patients or those with cardiac disease, in which elevated SNS activity may exacerbate underlying medical conditions.

    BACKGROUND: Asthma is a known risk factor for acute ozone-associated respiratory disease. Ozone causes an immediate decrease in lung function and increased airway inflammation. The role of atopy and asthma in modulation of ozone-induced inflammation has not been determined. OBJECTIVE: We sought to determine whether atopic status modulates ozone response phenotypes in human subjects. METHODS: Fifty volunteers (25 healthy volunteers, 14 atopic nonasthmatic subjects, and 11 atopic asthmatic subjects not requiring maintenance therapy) underwent a 0.4-ppm ozone exposure protocol. Ozone response was determined based on changes in lung function and induced sputum composition, including airway inflammatory cell concentration, cell-surface markers, and cytokine and hyaluronic acid concentrations. RESULTS: All cohorts experienced similar decreases in lung function after ozone. Atopic and atopic asthmatic subjects had increased sputum neutrophil numbers and IL-8 levels after ozone exposure; values did not significantly change in healthy volunteers. After ozone exposure, atopic asthmatic subjects had significantly increased sputum IL-6 and IL-1beta levels and airway macrophage Toll-like receptor 4, Fc(epsilon)RI, and CD23 expression; values in healthy volunteers and atopic nonasthmatic subjects showed no significant change. Atopic asthmatic subjects had significantly decreased IL-10 levels at baseline compared with healthy volunteers; IL-10 levels did not significa

    Full Text Available Anatomical studies of leaf and stem of twelve clones of Camellia were investigated. Cross sections of the stem of all the clones exhibited a typical pattern of arrangement of tissues characteristics of woody plants. Two types of idioblastic sclereids were found in the medullary parenchyma of the taxa studied. While astrosclereids werepresent in 10 of the twelve clones, the vesciculose sclereids were found only in the four clones belonging to C. sinensis. Leaves of the clones show variations in the number of palisade layers. Astro sclereids, brachy sclereids, and dendritic forms were observed in the leaves, their distribution varying in the different clones. A few other micromorphological features are also recorded. Our study forms a basis for answering uncertainties in taxonomic revision in the genus Camellia.

Then, we show that the physical sector is defined by three first-class constraints which preserve the full eleven-dimensional symmetry. Applying the same concepts to the eleven dimensional superparticle, taken off-shell, we discover a hidden twelve dimensional superPoincare symmetry that governs the theory.

    Premarital sex increases the risk of unintended pregnancy and sexually transmitted infections including HIV if unprotected and contraception is not used. Thus, the objective of this study was to assess premarital sex in the last twelve months and its predictors among regular undergraduate students of Wollega University. A cross-sectional survey using pretested, structured questionnaire was conducted on a total of 704 regular undergraduate students of Wollega University from February to March, 2014. We used multistage sampling technique to recruit study participants. Binary and multivariable logistic regressions were performed using SPSS version 20 to assess predictors of premarital sex. Statistical significance was determined through a 95% confidence level. Wollega University youths who had premarital sex in the last twelve months were 28.4%; 55.5% of them did not use condom during last sex while 31.3% engaged in multiple sex. Being male [Adjusted Odds Ratio (AOR)(95% Confidence Interval(CI))=2.7(1.58-4.75)], age 20-24 years [AOR(95%CI)=2.8(1.13-7.20)], training on how to use condom [AOR(95%CI)=1.7(1.17-2.46)], being tested for HIV [AOR(95%CI)=2.3(1.48-3.53)], using social media frequently [AOR(95%CI)=1.8(1.14-2.88)], having comprehensive knowledge of HIV [AOR(95% CI)=1.5(1.01-2.10)], alcohol use [AOR (95%CI)=2.2(1.31-3.56)] were associated with increased odds of premarital sex in the last twelve months. Nearly one-third of regular undergraduate students of the university were engaged in premarital sex in the last twelve months. Being male, using social media frequently and alcohol use were associated with increased odds of premarital sex in the stated period. Thus, higher institutions have to deliver abstinence messages alongside information about self-protection.

    Activation of AMP-activated protein kinase (AMPK) by exercise induces several cellular processes in muscle. Exercise activation of AMPK is unaffected in lean (BMI approximately 25 kg/m(2)) subjects with type 2 diabetes. However, most type 2 diabetic subjects are obese (BMI >30 kg/m(2)), and exercise stimulation of AMPK is blunted in obese rodents. We examined whether obese type 2 diabetic subjects have impaired exercise stimulation of AMPK, at different signaling levels, spanning from the upstream kinase, LKB1, to the putative AMPK targets, AS160 and peroxisome proliferator-activated receptor coactivator (PGC)-1alpha, involved in glucose transport regulation and mitochondrial biogenesis, respectively. Twelve type 2 diabetic, eight obese, and eight lean subjects exercised on a cycle ergometer for 40 min. Muscle biopsies were done before, during, and after exercise. Subjects underwent this protocol on two occasions, at low (50% Vo(2max)) and moderate (70% Vo(2max)) intensities, with a 4-6 week interval. Exercise had no effect on LKB1 activity. Exercise had a time- and intensity-dependent effect to increase AMPK activity and AS160 phosphorylation. Obese and type 2 diabetic subjects had attenuated exercise-stimulated AMPK activity and AS160 phosphorylation. Type 2 diabetic subjects had reduced basal PGC-1 gene expression but normal exercise-induced increases in PGC-1 expression. Our findings suggest that obese type 2 diabetic subjects may need to exercise at higher intensity to stimulate the AMPK-AS160 axis to the same level as lean subjects.

  9. Increased orbitofrontal brain activation after administration of a selective adenosine A2A antagonist in cocaine dependent subjects

    Directory of Open Access Journals (Sweden)

    F. Gerard eMoeller

    2012-05-01

    Full Text Available Background: Positron Emission Tomography imaging studies provide evidence of reduced dopamine function in cocaine dependent subjects in the striatum, which is correlated with prefrontal cortical glucose metabolism, particularly in the orbitofrontal cortex. However, whether enhancement of dopamine in the striatum in cocaine dependent subjects would be associated with changes in prefrontal cortical brain activation is unknown. One novel class of medications that enhance dopamine function via heteromer formation with dopamine receptors in the striatum is the selective adenosine A2A receptor antagonists. This study sought to determine the effects administration of the selective adenosine A2A receptor antagonist SYN115 on brain function in cocaine dependent subjects. Methodology/Principle Findings: Twelve cocaine dependent subjects underwent two fMRI scans (one after a dose of placebo and one after a dose of 100 mg of SYN115 while performing a working memory task with 3 levels of difficulty (3, 5, and 7 digits. fMRI results showed that for 7-digit working memory activation there was significantly greater activation from SYN115 compared to placebo in portions of left (L lateral orbitofrontal cortex, L insula, and L superior and middle temporal pole. Conclusion/Significance: These findings are consistent with enhanced dopamine function in the striatum in cocaine dependent subjects via blockade of adenosine A2A receptors producing increased brain activation in the orbitofrontal cortex and other cortical regions. This suggests that at least some of the changes in brain activation in prefrontal cortical regions in cocaine dependent subjects may be related to altered striatal dopamine function, and that enhancement of dopamine function via adenosine A2A receptor blockade could be explored further for amelioration of neurobehavioral deficits associated with chronic cocaine use.

    Abstract This study aimed to investigate the perioperative analgesic effect of a buprenorphine transdermal patch in patients who underwent simple lumbar discectomy. In total, 96 patients were randomly divided into parecoxib intravenous injection (Group A), oral celecoxib (Group B), and buprenorphine transdermal patch groups (Group C). The pain status, degree of satisfaction, adverse effects, and condition in which the patient received tramadol hydrochloride for uncontrolled pain were recorded on the night before surgery, postoperative day 1, postoperative day 3, and postoperative day 5. The degree of patient satisfaction in Group C was higher than that in Groups A and B, with minimal adverse effects. The buprenorphine transdermal patch had a better perioperative analgesic effect in patients who underwent simple lumbar discectomy. PMID:28514299

    Total hip replacement (THR) and total knee arthroplasty (TKA) carry a high risk of postoperative venous thromboembolism (VTE); therefore, anticoagulation prophylaxis is recommended in these patients. Unfortunately, there are no guidelines about VTE prophylaxis in patients with hemophilia who underwent these high-risk surgeries. To determine whether these patients have high risk of VTE, we conducted a retrospective study on patients with hemophilia who underwent elective THR/TKA at our institute from 2004 to 2012. Postoperatively, we collected information on duration and method of factor VIII/IX infusion, VTE-prophylaxis, and complications. There were 23 patients with hemophilia, 18 (78%) with hemophilia A and 5 (22%) with hemophilia B, who underwent high-risk surgeries (39% THR and 61% TKA). The VTE prophylaxis included sequential compression device, 12 (52%), and prophylactic enoxaparin, 1 (4%). Ten (43%) patients did not receive VTE prophylaxis. At 1-year follow-up, we did not find any evidence of clinical VTE in our patients. Better risk stratification is needed to identify patients who would benefit from pharmacological prophylaxis.

    The objective of this study was to determine the association of vaginal cuff length (VCL) with vaginal and pelvic recurrence rates in patients with cervical cancer who underwent radical hysterectomies. The clinicopathologic characteristics were collected from the medical records of 280 patients with cervical cancer who underwent radical hysterectomies. The association of VCL with 3-year vaginal and pelvic recurrence rates was determined using a Z-test. The association of VCL with other clinicopathologic characteristics was also determined. The VCL was not associated with 3-year vaginal and pelvic recurrence rates. The 3-year vaginal recurrence rate was 0%-2% and the 3-year pelvic recurrence rate was 7%-8%, independent of VCL. The VCL and the age of patients had an inverse relationship. However, the VCL was not associated with histologic type, FIGO stage, clinical tumor size, tumor size in the surgical specimen, depth of invasion, lymphovascular space invasion, parametrial involvement, lymph node involvement, and adjuvant therapy. One-hundred ninety of 280 patients (68%) underwent adjuvant therapies following radical hysterectomies. Although it is limited by the high rate of adjuvant therapy, the current study suggested that the VCL following radical hysterectomy in patients with cervical cancer was not associated with vaginal and pelvic recurrence rates.

    2008-01-01

    Full Text Available In order to extend the genetic data on the Sciaenidae fish family, the present study had the purpose to characterize PCR-generated 5S rDNA repeats of twelve species of this group through PAGE (Polyacrylamide Gel Electrophoresis analysis. The results showed the occurrence of at least two different 5S rDNA size classes in all the species. Moreover, 5S rDNA repeats of one of the studied species - Isopisthus parvipinnis - were cloned and subjected to nucleotide sequencing and Southern blot membrane hybridization analyses, which permitted to confirm the existence of two major 5S rDNA classes. Phylogenetic analysis based on the nucleotide sequences of different 5S rDNA repeats of I. parvipinnis lead to their separation into two major clusters. These results may reflect the high dynamism that rules the evolution rate of 5S rDNA repeats. The obtained data suggest that 5S rDNA can be useful in genetic analyses to identify species-specific markers and determine relationships among species of the Sciaenidae group.

    Despite the use of anatomic resection, the post-surgical recurrence rate remains high in early-stage non-small cell lung cancer (NSCLC). Chronic inflammation plays a role in the mechanism that promotes tumor initiation. This study aimed to investigate the association between recurrence outcome and chronic inflammation-related co-morbidities in early-stage resected NSCLC. A review of medical records for recurrence outcome and co-morbidities, in terms of chronic obstructive pulmonary disease (COPD), DM, asthma and cardiovascular diseases, was performed with 181 patients with stage I NSCLC that underwent anatomic resection. Subjects with T descriptors as T2a disease (49.5 vs. 28.0%, p recurrence. Univariate analysis for recurrence-free survival showed T descriptor as T2a (21.5 months vs. NR, p recurrence-free survival in the Cox regression model. Patients with COPD were at higher risk of brain recurrence (OR: 7.88; 95% CI, 1.50-41.3, p recurrence in bone and liver (OR: 4.13; 95% CI, 1.08-15.8, p = 0.05). Subjects with COPD and T2a disease had a higher risk of recurrence. The role of COPD as a recurrence promoter merits further prospective investigation.

  16. Definition of a Twelve-Point Polygonal SAA Boundaryfor the GLAST Mission

    The Gamma-Ray Large Area Space Telescope (GLAST), set to launch in early 2008, detects gamma rays within a huge energy range of 100 MeV - 300 GeV. Background cosmic radiation interferes with such detection resulting in confusion over distinguishing cosmic from gamma rays encountered. This quandary is resolved by encasing GLAST's Large Area Telescope (LAT) with an Anti-Coincidence Detector (ACD), a device which identifies and vetoes charged particles. The ACD accomplishes this through plastic scintillator tiles; when cosmic rays strike, photons produced induce currents in Photomultiplier Tubes (PMTs) attached to these tiles. However, as GLAST orbits Earth at altitudes {approx}550km and latitudes between -26 degree and 26 degree, it will confront the South Atlantic Anomaly (SAA), a region of high particle flux caused by trapped radiation in the geomagnetic field. Since the SAA flux would degrade the sensitivity of the ACD's PMTs over time, a determined boundary enclosing this region need be attained, signaling when to lower the voltage on the PMTs as a protective measure. The operational constraints on such a boundary require a convex SAA polygon with twelve edges, whose area is minimal ensuring GLAST has maximum observation time. The AP8 and PSB97 models describing the behavior of trapped radiation were used in analyzing the SAA and defining a convex SAA boundary of twelve sides. The smallest possible boundary was found to cover 14.58% of GLAST's observation time. Further analysis of defining a boundary safety margin to account for inaccuracies in the models reveals if the total SAA hull area is increased by {approx}20%, the loss of total observational area is < 5%. These twelve coordinates defining the SAA flux region are ready for implementation by the GLAST satellite.

    According to current guidelines, in patients without additional risk factors who underwent aortic valve replacement with a bioprosthesis, anticoagulation in the first 3 months after surgery is still a matter of debate. According to current evidence, aspirin in low doses is a reasonable alternative to vitamin K antagonists (VKA). We compared the incidence of thrombotic and hemorrhagic complications in patients with low thrombotic risk who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico. The hypothesis: aspirin as monotherapy has a beneficial effect compared to VKA. The studied patients were the low thrombotic risk patients who underwent aortic valve replacement with a bioprostesis in the National Institute of Cardiology of Ignacio Chávez of Mexico from 2011 to 2015. The groups studied were: aspirin only, VKA only and the combination of VKA plus aspirin. The patients were retrospectively followed during 12 months and the thrombotic and hemorrhagic complications were documented. Two hundred thirty-one patients were analized. Only one patient presented a hemorrhagic complication in the VKA only group. No thrombotic complications were observed. In the present study no thrombotic complications were observed in patients who did not receive anticoagulation in the first 3 months after a aortic valve replacement with a bioprosthesis after a follow up period of 12 months. This suggests that the use of aspirin only is safe during this period. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A. All rights reserved.

    Pure endoscopic resection has become the most popular surgical approach for pituitary adenoma. Intraoperative magnetic resonance imaging (iMRI) systems have been in use for endoscopic resection of pituitary adenomas. This study aimed to evaluate the effectiveness of iMRI and neuroimaging navigation techniques during endoscopic endonasal transsphenoidal surgery of pituitary adenomas. Data from 137 patients who underwent resection of endoscopic pituitary adenoma under 1.5T iMRI navigation were collected and analyzed. Of patients, 92 underwent complete resection and 45 had residual tumor on real-time iMRI. Twenty-three patients underwent further surgery, and total resection was achieved in 19. Extent of total resection increased from 67.15% to 81.02%. iMRI revealed 3 patients with bleeding in the surgical area, which was successfully treated during the surgery. Review images obtained 3 months after surgery showed 26 patients with residual tumor; 14 patients had the same volume as intraoperatively, and 12 patients had a volume less than that observed intraoperatively. Residual tumor volume in the suprasellar region was less than that seen intraoperatively in 11 of 15 (73.3%) patients. The use of iMRI and neuronavigation not only leads to a higher rate of tumor resection but also helps in detecting and removing hematomas in the surgical area. Follow-up examinations of extent of residual tumor at 3 months postoperatively were consistent with intraoperative results. Residual tumor volume in the suprasellar region was usually less than that observed intraoperatively. Copyright © 2017. Published by Elsevier Inc.

    The lung is a common site of metastases, whose prevalence varies as a function of the primary tumor site, which is usually colorectal cancer (CRC), breast carcinoma, or genitourinary cancers, such as ovary, urinary bladder and renal cell carcinomas. The aim of the present study was to analyze whether the site of primitive tumor affects overall survival (OS) of patients with lung metastases (LMs) who underwent pulmonary metastasectomy. The data of 41 patients with surgically treated CRC (Group A=22 patients) and non-colorectal carcinomas (Group B=19 patients), who developed matachronous LMs and underwent pulmonary metastasectomy with curative intent, were analyzed. The origin of non-colorectal LMs was genitourinary cancer in nine and breast cancer in 10 patients. Overall, there were 22 men and 19 women, with a median age of 65 years (range=31-80); 18 patients had a solitary metastatic tumor, while 23 had two or more LMs. Twenty-nine patients underwent wedge resection, through thoracotomy or video-assisted thoracic surgery, while 12 underwent pulmonary lobectomy. Seventy-five LMs were resected with a 5-tear OS of 48.8%. No difference was found between elderly (≥65 year-old) and younger patients (p=0.26), and between those with solitary or multiple LMs (p=0.62) in terms of survival rate. The female patients had a worse OS (31.6% vs. 63.6%; odds ratio (OR)=3.79, 95% confidence interval (CI)=1.03-13.91, p=0.003) compared to males, independent of the origin of primary cancer. There was no difference in the cumulative survival rates (OR=1.65, 95%CI=0.48-5.69, p=0.42) between Groups and the log-rank test (p=0.75) was not significant. In conclusion, the main pathological characteristics of metastatic lesions and advanced age do not appear to be associated with a poor prognosis in patients with LMs, while the female gender is a negative prognostic factor. Thus, the primary tumor site should not be considered a major criterion in selecting patients for pulmonary

    Dissecting how genetic and environmental influences impact on learning is helpful for maximizing numeracy and literacy. Here we show, using twin and genome-wide analysis, that there is a substantial genetic component to children's ability in reading and mathematics, and estimate that around one half of the observed correlation in these traits is due to shared genetic effects (so-called Generalist Genes). Thus, our results highlight the potential role of the learning environment in contributing to differences in a child's cognitive abilities at age twelve.

    Direct chromosome analysis and FISH were performed on twelve primary gastric carcinomas. Two of them had simple chromosome changes: 48,XX, +8, +20, and 49, XY, +2, +8, +9, and the others had complicated chromosome changes, which includes much more numerical and structural chromosome aberrations. Frequent structural changes in the complicated types involved chromosome 7, 3, 1, 5 and 12 etc. The del 7q was noted in eight cases. The del (3p) and del (1p) were noted in six and five cases, respectively. The results provide some important clues for isolation of the genes related to gastric cancer.

    A culture of learning in providing health services and education for health professionals is a constant challenge for individuals, team and organizations. The importance of such a culture was highlighted by the findings of the Bristol Royal Infirmary Inquiry (2001). This was discussed in the context of the literature on the Learning Organization (Senge, 1990) at the 2004 Association of Medical Education in Europe (AMEE) conference, and reviewed a year later at the 2005 AMEE conference. This paper outlines twelve tips for educational and health service organizations in facilitating a culture of learning for their members and also offers specific advice to individual students and professionals.

    Introduction The role of the speech-language pathology in the multiprofessional team dealing with laryngology and the voice has been recognized for a long time. Scientific studies in this field recommend therapies for laryngeal microsurgeries; few of the studies, however, effectively evaluate the result of postoperative speech therapy. Objective To compare speech therapy evaluation and treatment among patients with phonotraumatic lesions and patients with lesions unrelated to phonotrauma who underwent laryngeal microsurgery. Methods This study was performed at IPO Hospital (Paranaense Institute of Otorhinolaryngology, Curitiba, Paraná, Brazil) between February 2010 and February 2011. Of 254 patients who underwent laryngeal microsurgery, 208 patients were included in the study and divided in two groups: group A with phonotraumatic lesions (n = 131) and group B with lesions unrelated to phonotrauma (n = 77). The number of sessions and the functional result after speech therapy were evaluated. Results The number of postoperative phonotherapy sessions after microsurgery was up to 10 sessions in 89.31% and 87.71% for groups A and B, respectively. Phonotherapy treatment showed a better functional evolution in group A (92.37%). Conclusion A significant difference was observed only in functional evolution, which was better in the group with phonotraumatic lesions (p < 0.0001). PMID:25992078

    Full Text Available Abstract Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74 underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90% were in NYHA class III; 34 (85% patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results: While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion: Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique. Its rate for returning to sinus rhythm is as high as the rate of conventional surgical procedure.

    Background Patients with malignant pleural effusion have a limited life expectancy. An increase in pleural and oncological treatment options and more accurate prognostic evaluation may help individualize treatment strategies. The aim of this study was to identify the prognostic indicators of overall survival (OS) after video‐assisted thoracic surgery (VATS) talc pleurodesis for malignant pleural effusion. Methods We examined the medical records of all consecutive patients with malignant pleural effusion who underwent VATS talc pleurodesis from 2006 to 2008 at the Samsung Medical Center. Univariate and multivariate analyses were used to identify predictors of OS after VATS talc pleurodesis. Results During the study period, 91 patients underwent VATS talc pleurodesis to treat malignant pleural effusion. Early (within 30 days) and late (within 90 days) postoperative mortality rates were 9.9% (9 patients), and 25.3% (23), respectively. Median survival time after VATS talc pleurodesis was 10.5 months. The postoperative respiratory complication rate was 11% (10 patients), and included pneumonia (9) and acute respiratory distress syndrome (4). Multivariate analysis revealed that preoperative chemotherapy (P = 0.012), preoperative radiotherapy (P = 0.003), and Eastern Cooperative Oncology Group (ECOG) performance score 3 or 4 (P = 0.013) were independent risk factors of OS after VATS talc pleurodesis. Conclusions We identified previous chemotherapy or radiotherapy and poor performance status (ECOG 3 or 4) as significant predictors of OS after VATS talc pleurodesis. These prognostic factors can help surgeons select candidates for VATS pleurodesis for malignant pleural effusion. PMID:27385980

    A 2-year-and-4-month-old female infant, 12 kg in weight and 90 cm in height fell off from a table, which was about 1 m height with a toothbrush in her mouth without her parents noticing. Urgent CT scan showed that it penetrated the left side of her oropharyngeal wall to the bifurcation of her right carotid artery. According to the initial assessment, carotid artery seemed intact and there seemed to be no sign of CNS involvement. She underwent general anesthesia for further investigation and operation. We could detect vocal code with ease by inserting Glidescope between her tongue and the toothbrush. After the intubation, we administered fentanyl 25 μg rocuronium 15 mg and sevoflulane 3-5% to her, and then she underwent arteriography. The neurosurgeon found no sign of major arterial injury nor traumatic aneurysm nor CNS involvement. She went to the ICU intubated after the removal of the toothbrush. She was extubated 5 days after operation. One of the benefits of the Glidescope is that we can share the visual image, and we chose it this time. When we expect a difficult airway during management for oropharyngeal trauma, we have to consider the way to manage the airway.

    A workplace's design can have various positive or negative effects on the employees and since the 1970s the advantages and disadvantages of open-plan offices have been discussed. The aim of this study was to investigate perceived health, work environment and self-estimated productivity one month before and at three, six and twelve months after relocation from individual offices to an open-plan office environment. Employees from three departments within the same company group and who worked with relatively similar tasks and who were planned to be relocated from private offices to open-plan offices were invited to participate. Questionnaires comprising items from The Salutogenic Health Indicator Scale, The Work Experience Measurement Scale, the questionnaire by Brennan et al. about perceived performance and one question from the Work Ability Index were sent to participants one month before relocation (baseline) to open-plan offices and then at three, six and twelve months after relocation. At baseline, 82 questionnaires were sent out. The response rate was 85%. At the follow-ups 77-79 questionnaires were sent out and the response-rate was 70%-81%. At follow-ups, perceived health, job satisfaction and performance had generally deteriorated. The results of the study indicate that employees' perception of health, work environment and performance decreased during a 12 month period following relocation from individual offices to open-plan offices.

    We propose an approach to the study of the evolution of high-apogee twelve-hour orbits of artificial Earth's satellites. We describe parameters of the motion model used for the artificial Earth's satellite such that the principal gravitational perturbations of the Moon and Sun, nonsphericity of the Earth, and perturbations from the light pressure force are approximately taken into account. To solve the system of averaged equations describing the evolution of the orbit parameters of an artificial satellite, we use both numeric and analytic methods. To select initial parameters of the twelve-hour orbit, we assume that the path of the satellite along the surface of the Earth is stable. Results obtained by the analytic method and by the numerical integration of the evolving system are compared. For intervals of several years, we obtain estimates of oscillation periods and amplitudes for orbital elements. To verify the results and estimate the precision of the method, we use the numerical integration of rigorous (not averaged) equations of motion of the artificial satellite: they take into account forces acting on the satellite substantially more completely and precisely. The described method can be applied not only to the investigation of orbit evolutions of artificial satellites of the Earth; it can be applied to the investigation of the orbit evolution for other planets of the Solar system provided that the corresponding research problem will arise in the future and the considered special class of resonance orbits of satellites will be used for that purpose.

    Global surface temperature change is one of the most important aspects in global climate change research. In this study, in order to overcome shortcomings of traditional observation methods in meteorology, a new method is proposed to calculate global mean surface temperature based on remote sensing data. We found that (1) the global mean surface temperature was close to 14.35 °C from 2001 to 2012, and the warmest and coldest surface temperatures of the global in the recent twelve years occurred in 2005 and 2008, respectively; (2) the warmest and coldest surface temperatures on the global land surface occurred in 2005 and 2001, respectively, and on the global ocean surface in 2010 and 2008, respectively; and (3) in recent twelve years, although most regions (especially the Southern Hemisphere) are warming, global warming is yet controversial because it is cooling in the central and eastern regions of Pacific Ocean, northern regions of the Atlantic Ocean, northern regions of China, Mongolia, southern regions of Russia, western regions of Canada and America, the eastern and northern regions of Australia, and the southern tip of Africa. The analysis of daily and seasonal temperature change indicates that the temperature change is mainly caused by the variation of orbit of celestial body. A big data model based on orbit position and gravitational-magmatic change of celestial body with the solar or the galactic system should be built and taken into account for climate and ecosystems change at a large spatial-temporal scale.

Incidence and prognosis of tumor deposits in stage I, II, and III colorectal cancer patients has been explored. The aim of this study was to determine the prognostic value of tumor deposits in stage IV colorectal cancer patients who underwent simultaneous resection for synchronous colorectal liver metastases (SCRLM.Methods: Clinicopathological and outcome data of 146 consecutive SCRLM patients who underwent simultaneous R0 resection between July 2003 and July 2013 were collected from our prospectively established SCRLM database. The prognostic value of tumor deposits was evaluated by Kaplan–Meier and Cox regression analysis.Results: Tumor deposits were detected in 41.8% (61/146 of these SCRLM patients. Tumor deposits were significantly correlated with lymph node metastasis and nerve invasion of the primary tumors (P=0.002, P=0.041; respectively. The Kaplan–Meier survival analysis revealed that the overall survival (OS and disease-free survival (DFS of SCRLM patients with tumor deposits were significantly poorer than those with no tumor deposits (P=0.039, P=0.001; respectively. And with multivariate analysis, we found that positive tumor deposits were significantly associated with shorter DFS independent of lymph node status (P=0.002. Subgroup analysis found that of the 57 SCRLM patients with negative lymph node status, the OS and DFS of patients with positive tumor deposits were significantly shorter than those with negative tumor deposits (P=0.002 and P=0.031, respectively.

    Patients who undergo cardiac surgery appear to be at increased risk for the development of Nosocomial infections (NIs). The development of antibiotic-resistant infections has been associated with significantly greater hospital mortality rates compared to similar infections caused by antibiotic-sensitive pathogens. The purpose of this study is survey of Nis and antibiotic resistance patterns of causative bacteria among patients who underwent open heart surgery in the north of Iran during a 2-year period between September 2012 and September 2014. In this cross-sectional study we evaluated 187 patients that underwent open heart surgery with NIs. Demographic feature, clinical characteristics and risk factors of each infection were recorded. The antibiotic susceptibility test was performed using the Minimum inhibitory concentration (MIC) method according to the standard protocol of Clinical & Laboratory Standards Institute (CLSI). Detection of Extended-spectrum beta-lactamase (ESBL) producing bacteria was performed by the double-disk synergy (DDS) test; also Methicillin-resistant Staphylococcus (MRSA) strains were identified by MRSA Screen Agar. The collected data were analyzed using the SPSS software (ver. 16) and, descriptive statistics were used. Out Of total of 2253 hospitalized patients who underwent open heart surgery, 187(5.05%) patients had NIs. 51.9% of the patients were female. The rates of surgical site infection (SSI), respiratory tract infection, endocarditis, Urinary tract infection (UTI), blood Infection and mediastinitis were 27.80, 25.66%, 17.64, 17.11% 8.55% and 3.20% respectively. E.coli and S.aureus were the most causative agents of NIs. The rate of ESBL-producing bacteria was 14.28- 71.42% among enterobacteriaceae and the rate of MRSA was 54.2% among S.aureus strains. All isolated Acinetobacter.spp were Multi-drug resistance (MDR). We showed that the rate of NIs among these high-risk patients was in the average level. But the emergence of MRSA and

    Full Text Available Amiodarone is used commonly and effectively in the treatment of arrhythmia; however, it may cause thyrotoxicosis categorized into two types: iodine-induced hyperthyroidism (type 1 amiodarone-induced thyrotoxicosis (AIT and destructive thyroiditis (type 2 AIT. We experienced a case of type 2 AIT, in which high-dose steroid was administered intravenously, and we finally decided to perform total thyroidectomy, resulting in a complete cure of the AIT. Even though steroid had been administered to the patient (maximum 80 mg of prednisolone, the operation was performed safely and no acute adrenal crisis as steroid withdrawal syndrome was found after the operation. Few cases of type 2 AIT that underwent total thyroidectomy with high-dose steroid administration have been reported. The current case suggests that total thyroidectomy should be taken into consideration for patients with AIT who cannot be controlled by medical treatment and even in those under high-dose steroid administration.

    Posterior reversible encephalopathy syndrome (PRES) usually manifests with severe headaches, seizures, and visual disturbances due to uncontrollable hypertension. A patient (age in the early 60s) with a history of renal cell cancer presented with lower-extremity weakness and paresthesias. Magnetic resonance imaging (MRI) of the thoracic spine revealed a T8 vertebral body metastatic lesion with cord compression at that level. The patient underwent preoperative embolization of the tumor followed by posterior resection and placement of percutaneous pedicle screws and rods. Postoperatively, the patient experienced decreased visual acuity bilaterally. Abnormal MRI findings consisted of T2 hyperintense lesions and fluid-attenuated inversion recovery changes in both occipital lobes, consistent with the unique brain imaging pattern associated with PRES. The patient’s blood pressure was normal and stable from the first day of hospitalization. The patient was kept on high-dose steroid therapy, which was started intraoperatively, and improved within 48 hours after symptom onset. PMID:26858804

    We report a case of 70 years old male who underwent percutaneous nephrolithotomy for renal calculi. After an uneventful recovery from anaesthesia, the patient developed delirium which manifested as restlessness, agitation, irritability and combative behavior. All other clinical parameters including arterial blood gas, chest X-ray and core temperature were normal and the patient remained haemodynamically stable. But 45 min later the patient developed florid manifestations of septic shock. He was aggressively managed in a protocolized manner as per the Surviving Sepsis Guidelines in the Critical Care Unit and recovered completely. There are no case reports showing postoperative delirium as the only initial presentation of severe sepsis, with other clinical parameters remaining normal. Both urosepsis and sepsis associated delirium have very high mortality. High index of suspicion and a protocolized approach in the management of sepsis can save lives.

    Full Text Available Autotransplantation of spleen tissue is an attempt for maintenance of splenic functions when splenectomy is indicated in children. It minimizes the risks of overwhelming postsplenectomy infection and it has been done in children with severe portal hypertension due to hepatosplenic mansonic schistosomiasis that underwent splenectomy. The purposes of this investigation were to study the morphology of the residual splenic tissue; to evaluate the residual filtration function of this splenosis; and to assess the immune response to polyvalent pneumococcal vaccine of these patients. Twenty-three children with portal hypertension from mansonic schistosomiasis who underwent splenectomy, ligature of the left gastric vein, autotransplantation of spleen tissue into an omental pouch were evaluated for residual splenic parenchyma and functions. Tc-99m sulfur colloid liver-spleen scans were used for detection of splenic nodules. The search for Howell Jolly bodies were used for assessing the filtration function and Enzyme-linked immunosorbent assay was used for measuring the relative rise in titter of specific pneumococcal antibodies. Splenosis was evident in all children; however, in two there were less than five splenic nodules in the greater omentum, which was considered insufficient. Howell-Jolly bodies were found in the peripheral blood only in these two patients with less evident splenosis. The immune response was adequate in 15 patients; it was intermediate in 4 patients and inadequate in 4 patients. Autotransplantation of spleen tissue into an omental pouch is efficient in maintaining the filtration splenic function in more than 90% of the cases and the immune response to pneumococcal vaccination in approximately 65% of the children.

    Patients with diabetes mellitus (DM) are at twofold to fourfold higher cardiovascular risk than those without DM. Serum levels of lipoprotein(a) (Lp(a)) can be risk factors for adverse events. However, the clinical implications of Lp(a) in patients with DM who underwent percutaneous coronary intervention (PCI) is unknown. The aim of the study was to determine the role of Lp(a) in patients with DM who underwent PCI. A total of 3,508 patients were treated by PCI from 1997 to 2011 at our institution. Among them, we analyzed consecutive 1,546 patients with DM. Eligible 1,136 patients were divided into 2 groups (high Lp(a) [n = 575] and low Lp(a) [n = 561]) by the median of Lp(a) levels. The number of chronic kidney disease, multivessel disease, and the level of LDL-C were higher in the group with high Lp(a) than with low Lp(a). The median follow-up period was 4.7 years. Event rate of all-cause death was same between the 2 groups (p = 0.37). However, cumulative incidence of cardiac death and acute coronary syndrome was significantly higher in the high Lp(a) than in the low Lp(a) group (p = 0.03). Multivariable analysis selected a high Lp(a) level as an independent predictor of cardiac death and acute coronary syndrome (hazard ratio 1.20; 95% confidence interval 1.00 to 1.42; p = 0.04). In conclusion, a high Lp(a) value could be associated with advanced cardiac events after PCI for patients with DM. Copyright © 2016 Elsevier Inc. All rights reserved.

    The soft and periodontal tissues surrounding dental implants are particularly susceptible to bacteria invasion and inflammatory reactions due to complex histological structures. This study was carried out to investigate the influence of a propolis-containing hygienic agent on selected oral health parameters, oral microflora, and the condition of periodontal health. Sixteen subjects who underwent an oral rehabilitation with dental implants were selected and randomly assigned into two groups, which received a newly formulated propolis-containing toothpaste (3% (CA)) or a negative control without an active ingredient (CC). Approximal plaque index (API), oral hygiene index (OHI, debris component), and sulcus bleeding index (SBI) were assessed in three subsequent stages. During the first and last examinations, the swabs were employed for microbiological inoculation. Propolis-containing toothpaste was found to be distinctively effective in improving oral health and the occurrence of gingivitis triggered by dental plaque. The qualitative and quantitative changes in oral bacteria spectrum were observed. Antibacterial measures containing propolis might be used as a natural adjuvant to other active substances in individuals with a high risk of periodontal problems against pathogenic oral microflora.

    Full Text Available This paper will discuss the aspects of content schemata in second language reading among diploma level students who were taking a reading course in Universiti Teknologi MARA Perlis. In this qualitative case study, the researcher had selected two short stories that are categorized as content-familiar texts, i.e. The Hunted Fox and Twelve and Not Stupid. Six participants were asked to write a 150-word entry response on the short story and a grading criteria was used to assess the participants’ level of comprehension. An in-depth interview was also conducted on each participant. The entry responses and the interview patterns were analyzed to determine whether content schemata had contributed to the learners’ understanding of the text. This study discovered that content schemata had contributed to the learners’ understanding of the text because the learners’ comprehension was facilitated by their background knowledge on the content-familiar texts.

    The genus Porphyra (and its sister genus Pyropia) contains important red algal species that are cultivated and/or harvested for human consumption, sustaining a billion-dollar aquaculture industry. A vast amount of research has been focused on species of this genus, including studies on genetics and genomics among other areas. Twelve novel microsatellite markers were developed here for Porphyra linearis. Markers were characterized using 32 individuals collected from four natural populations of P. linearis with total heterozygosity varying from 0.098 to 0.916. The number of alleles per locus ranged from 2 to 18. All markers showed cross amplification with Porphyra umbilicalis and/or Porphyra dioica. These polymorphic microsatellite markers are useful for investigating population genetic diversity and differentiation in P. linearis and may become useful for other genetic research on the reproductive biology of this important species.

    Human milk is a rich source of bioactive proteins that support the early growth and development of the newborn. Although the major components of the protein fraction in human milk have been studied, the expression and relative abundance of minor components have received limited attention. We examined the expression of low-abundance proteins in the whey fraction of human milk and their dynamic changes over a twelve-month lactation period. The low-abundance proteins were enriched by ProteoMiner beads, and protein identification was performed by liquid chromatography tandem mass spectrometry. One hundred and fifteen proteins were identified, thirty-eight of which have not been previously reported in human colostrum or milk. We also for the first time described differences in protein patterns among the low-abundance proteins during lactation. These results enhance our knowledge about the complexity of the human milk proteome, which constitutes part of the advantages to the breast-fed infant.

    Massive open online courses (MOOCs) are a novel mode of online learning. They are typically based on higher education courses and can attract a high number of learners, often in the thousands. They are distinct from on-campus education and deliver the learning objectives through a series of short videos, recommended readings and discussion fora, alongside automated assessments. Within medical education the role of MOOCs remains unclear, with recent proposals including continuing professional development, interprofessional education or integration into campus-based blended learning curricula. In this twelve tips article, we aim to provide a framework for readers to use when developing, delivering and evaluating a MOOC within medical education based on the literature and our own experience. Practical advice is provided on how to design the appropriate curriculum, engage with learners on the platform, select suitable assessments, and comprehensively evaluate the impact of your course.

    Twelve novel 7'-hydroxy lignan glucosides (1-12), including two benzofuran-type neolignans, two 8-O-4' neolignans, two dibenzylbutyrolactone lignans, and six tetrahydrofuranoid lignans, together with six known lignan glucosides (13-18), were isolated from the fruit of Arctium lappa L. (Asteraceae), commonly known as Arctii Fructus. Their structures were elucidated using spectroscopy (1D and 2D NMR, MS, IR, ORD, and UV) and on the basis of chemical evidence. The absolute configurations of compounds 1-12 were confirmed using rotating frame nuclear overhauser effect spectroscopy (ROESY), the circular dichroic (CD) exciton chirality method, and Rh2(OCOCF3)4-induced CD spectrum analysis. All of the isolated compounds were tested for hepatoprotective effects against D-galactosamine-induced cytotoxicity in HL-7702 hepatic cells. Compounds 1, 2, 7-12, and 17 showed significantly stronger hepatoprotective activity than the positive control bicyclol at a concentration of 1 × 10(-5) M.

    Review of studies published in medical education journals over the last decade reveals that teaching medical professionalism is essential, yet challenging. According to a recent Best Evidence in Medical Education (BEME) guide, there is no consensus on a theoretical or practical model to integrate the teaching of professionalism into medical education. The aim of this article is to outline a practical manual for teaching professionalism at all levels of medical education. Drawing from research literature and author's experience, Twelve Tips are listed and organised in four clusters with relevance to (1) the context, (2) the teachers, (3) the curriculum, and (4) the networking. With a better understanding of the guiding educational principles for teaching medical professionalism, medical educators will be able to teach one of the most challenging constructs in medical education.

  14. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    2011-02-01

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other.

    Background: The aim of this study was to evaluate the efficacy of low-level laser therapy for reducing the acute pain of sternotomy in patients who underwent a coronary artery bypass graft (CABG). Methods: This study was conducted with ninety volunteers who electively submitted to CABG. The volunteers were randomly allocated into three groups of equal size (n = 30): control, placebo, and laser (λ of 660 nm and spatial average energy fluency of 1.06 J/cm2). Pain when coughing was assessed by a visual analog scale (VAS) and McGill Pain Questionnaire, according to sensory, affective, evaluative, and miscellaneous domains. The patients were followed for 1 month after the surgery. Results: The laser group had a greater decrease in pain with analogous results, as indicated by both the VAS and the McGill questionnaire (P ≤ 0.05) on sensory and affective scores, on days 6 and 8 postsurgery compared to the placebo and control groups. Conclusion: Laser seems to be effective promoting pain reduction after coronary-arterial bypass grafting. PMID:28074796

    Patients who underwent resection of maxilla due to benign or malignant tumor, or accident will have defect in palatal area. They get retention, support and stability from remaining tissues which are hardly optimal. The advantage of swing-lock attachment design is having multiple contacts on labial and lingual side of the abutment teeth by retentive strut and palatal bracing component. Because the force is distributed equally to abutment teeth, abutment teeth of poor prognosis can be benefited from it. It is also more advantageous to cover soft tissue defects which are hard to reach with conventional prosthesis. A 56-year-old female patient who had undergone a maxillectomy due to malignant melanoma complaining of loose and unstable surgical obturator. Surveyed crowns were placed on #12, 26, and 27. Teeth #11, 21, 22, and 23 had lingual rest seat and #24 had mesial rest seat to improve stability and support of the obturator. This clinical report presents the prosthetic management of a patient treated with obturator on the maxilla using swing-lock attachment to the remaining teeth. PMID:27826392

    AIM: To asses the relationship between severity of gastroesophageal refluxe disease and Epworth sleepiness scale as an indicator of daytime somnolence.METHODS: One hundred and thirty-four patients underwent an upper panendoscopy as indicated by the typical reflux symptoms and were also investigated with regard to somnolence. Sleepiness was evaluated by Epworth Sleepiness Scale, which was compared to the severity of endoscopic findings (Savary-Miller/modified by Siewert). Patients with psychiatric disorders or being on sedato-hypnotics as well as shift workers were excluded from the study. The relationship between the severity of the reflux disease and daytime somnolence was analyzed with the help of multivariate regression analysis.RESULTS: A positive tendency was found between the severity of the reflux disease and the corresponding Epworth Sleepiness Scale. In the case of the more severe type -Savary-Miller Ⅲ - at least a mild hypersomnia was found.For this group daytime somnolence was significantly higher than in the case of the non-erosive type of Gastroesophageal Reflux Disease representing the mildest stage of reflux disease.CONCLUSION: The severity of Gastroesophageal Reflux Disease influences daytime somnolence.

    To evaluate the effects of preoperative highly sensitive C-reactive protein (Hs-CRP) in serum on the prognostic outcomes of patients with hepatocellular carcinoma (HCC) following hepatic resection in Chinese samples.From January 2004 to December 2008, a total of 624 consecutive HCC patients who underwent hepatic resection were incorporated. Serum levels of Hs-CRP were tested at preoperation via a collection of venous blood samples. Survival analyses adopted the univariate and multivariate analyses.In our study, among the 624 screened HCC patients, 516 patients were eventually incorporated and completed follow-up. Positive correlations were found regarding preoperative serum Hs-CRP level and tumor size, Child-Pugh class, or tumor stage (all P Hs-CRP levels at preoperation (both P Hs-CRP-normal group, the overall survival (OS) and recurrence-free survival rates were evidently decreased in the Hs-CRP-elevated group. Further, preoperative serum Hs-CRP level might be having possible prediction effect regarding survival and recurrence of HCC patients after hepatic section in the multivariate analysis.Preoperative increased serum Hs-CRP level was an independent prognostic indicator in patients with HCC following hepatic resection in Chinese samples.

Theobjective of this study is to evaluate the parameters of quality oflife of 23 patients who underwent surgery for anterior cruciateligament reconstruction. Methods: We adopted SF-36, a generichealth-related evaluation questionnaire, to obtain informationregarding several aspects of patients’ health conditions, and theLysholm questionnaire, specific to evaluate the symptoms andfunction of the knee. The questionnaires were applied at two stagesof the treatment: pre- and postoperatively (after the rehabilitationprogram. Results: Before surgery, the Lysholm questionnairepresented the following results: excellent in 4% of the cases, goodin 22%, fair in 22%, and poor in 52%. After surgery (Lysholm e SF-36 the correlation level was approximately 44% (p = 0.041.Discussion: The correlation between the Lysholm and the SF-36questionnaires showed the following: the lower the level of pain,the higher the Lysholm score. The high scores presented by theLysholm questionnaire are directly proportional to physical andemotional aspects, and to functional capacity. Conclusion:Analysis of both questionnaires, as well as of their correlation,showed some improvement in patients´ quality of life. We werealso able to demonstrate the importance and usefulness of applyingthe two questionnaires at three different moments: before, duringand after physiotherapeutic intervention.

    Laser cordectomy (LC) or radiotherapy (RT) is often recommended in the early stage of laryngeal cancer. We conducted perceptual and acoustic analysis to compare sustained vowel and stop consonants since there is no article evaluating both the sustained vowel and stop consonants. Eventually, we might determine which management is superior in terms of speech production. A total of 28 patients who underwent LC and RT for early T1 glottic cancer were selected. The sustained vowel /a/ and bilabial stop consonants were used to assess the perceptual scores. The fundamental frequency (Fo), jitter, shimmer and noise-to-harmonic ratio (NHR) levels for sustained vowels were evaluated. Voice onset time (VOT), vowel duration (VD) and closure duration of the bilabial plosives were analyzed. A receiver operating characteristic curve analysis was used to evaluate significant results statistically. The GRBAS and discrimination scores were not significantly different between two groups. Fo and jitter were significantly higher in the LC than RT. The cut-off value was statistically higher in the LC group and statistically lower in the RT group. The VOT was significantly longer in the LC than RT. The cut-off value of the /pipida/ VOT was statistically longer in the LC group and statistically shorter in the RT group. The differences may have been due to muscular fibrosis after RT. Movements of vocal cords with fibrosis were sluggish, when impulsion developed to pronounce the initial /p/ sound, so the VOT was shortened and the VD was longer after RT.

    Visual deprivation may lead to enhanced performance in other sensory modalities. Whether this is the case in the tactile modality is controversial and may depend upon specific training and experience. We compared the performance of sighted subjects on a Braille character discrimination task to that of normal individuals blindfolded for a period of five days. Some participants in each group (blindfolded and sighted) received intensive Braille training to offset the effects of experience. Blindfolded subjects performed better than sighted subjects in the Braille discrimination task, irrespective of tactile training. For the left index finger, which had not been used in the formal Braille classes, blindfolding had no effect on performance while subjects who underwent tactile training outperformed non-stimulated participants. These results suggest that visual deprivation speeds up Braille learning and may be associated with behaviorally relevant neuroplastic changes.

    The relationship between transthoracic needle biopsy (TTNB) and pleural recurrence of cancer after curative lung resection remains unclear. We aimed to assess whether TTNB increases the ipsilateral pleural recurrence (IPR) rate and identify other potential risk factors for pleural recurrence after surgery. This retrospective study included 392 patients with p-stage I non-small cell lung cancer with solid or part-solid nodules after curative lung resection in 2009-2010. Imbalances among the characteristics were adjusted using an inverse probability-weighted method based on propensity scoring. Multivariate Cox's regression analysis and the Kaplan-Meier method were used to determine independent risk factors for IPR. A total of 243 (62%) patients received TTNB, while 149 (38%) underwent an alternate, or no, diagnostic technique. IPR was significantly more frequent in the TTNB group (p=0.004), while total recurrence was similar between the groups (p=0.098). After applying the weighted model, diagnostic TTNB (hazard ratio [HR], 5.27; 95% confidence interval [CI], 1.49-18.69; p=0.010), microscopic visceral pleural invasion (HR, 2.76; 95% CI, 1.08-7.01; p=0.033) and microscopic lymphatic invasion (HR, 3.25; 95% CI, 1.30-8.10; p=0.012) were associated with an increased frequency of IPR. Among patients who received TTNB, microscopic lymphatic invasion was a risk factor for IPR (HR, 2.74; 95% CI, 1.10-6.79; p=0.030). The diagnostic TTNB procedure is associated with pleural recurrence but may be unrelated to overall recurrence-free survival in early lung cancer. Moreover, microscopic lymphatic invasion could be a risk factor for pleural recurrence. TTNB should be carefully considered before lung resection and close follow-up to detect if pleural recurrence is needed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Few studies of hypospadias repair in childhood have used validated questionnaires to investigate outcomes of cosmesis, urinary function, and sexual function in adulthood. We sought to investigate long-term outcomes in adult patients who had undergone severe hypospadias repair as children using an existing web-based application available to multiple institutions in order to develop an online patient survey of previously validated questionnaires. Patients aged 18 years or older who underwent severe hypospadias repair between 1992 and 1997 at our institution were contacted to complete an online survey. Through medical chart reviews, we analyzed the location of meatus, type of repair, and complications. The online survey included questions about penile appearance, and validated questionnaires to assess urinary and sexual function. Of 58 patients who met the inclusion criteria, we contacted 19, and 13 completed the survey. Fifty-nine percent had complications, with an average of 2.2 procedures per patient. Most (85.0%) were satisfied with penile appearance, although 38.0% had residual penile curvature. Hypospadias patients had mean lower orgasmic function than normal controls. Mean scores for urinary function and other domains of sexual function were similar to normal controls. Although the majority of adult patients were satisfied with the outcomes of penile appearance, urinary function, and sexual function, our online survey suggests decreased lower orgasmic function as measured by validated questionnaire. An online survey accessible to multiple institutions with validated questionnaires may facilitate assessment of long-term hypospadias results. Copyright © 2014 Journal of Pediatric Urology Company.

    Full Text Available Our hypothesis is that the location of the seminal vesicles near the base of the prostate, the more positive cores are detected in the base, the greater the risk of seminal vesicle invasion. Therefore we investigate the clinical outcomes of base dominant prostate cancer (BDPC in transrectal ultrasound (TRUS -guided biopsies compared with anteromiddle dominant prostate cancer (AMPC.From November 2003 to June 2014, a total of 990 intermediate and high risk prostate cancer (PCa patients who underwent radical prostatectomy (RP were enrolled and stratified into two groups according to proportion of positive cores-BDPC group had ≥ 33.3% ratio of positive cores from the prostate base among all positive cores and AMPC group < 33.3% in systemic biopsy. Between two groups, we compared the rate of pathologic outcomes and biochemical recurrence (BCR. We performed multivariate logistic regression model to confirm the significance of BDPC to seminal vesicle invasion (SVI and Cox proportional hazard analysis to BCR.Among these 990 PCa patients, the 487 patients in BDPC group had more advanced clinical stage (p<0.001, a higher biopsy GS (p = 0.002, and a higher rate of extracapsular extension (ECE, SVI and BCR (all p<0.001 than AMPC group. The patients in BDPC group had poor BCR free survival rate via Kaplan-meier analysis (p<0.001. The ratio of the base positive cores was a significant predictor to SVI in multivariate analysis (p < 0.001 and significant predictor of BCR in multivariate Cox proportional analysis (hazard ratio: 1.466, p = 0.004.BDPC in TRUS-guided prostate biopsies was significantly associated with SVI and BCR after adjusting for other clinical factors. Therefore, BDPC should be considered to be a more aggressive tumor despite an otherwise similar cancer profile.

    The clinical practice guidelines recommend measuring serum testosterone in patients with prostate cancer (PC) who undergo castration. The serum testosterone concentration should be <50ng/dL, a level established by using a radioimmunoassay method. The use of chemiluminescent immunoassays (IA) has become widespread, although their metrological characteristics do not seem appropriate for quantifying low testosterone concentrations. The objective of this review is to analyse the methods for quantifying testosterone and to establish whether there is scientific evidence that justifies measuring it in patients with PC who undergo castration, through liquid chromatography attached to a mass spectrometry in tandem (LC-MSMS). We performed a search in PubMed with the following MeSH terms: measurement, testosterone, androgen suppression and prostate cancer. We selected 12 studies that compared the metrological characteristics of various methods for quantifying serum testosterone compared with MS detection methods. IAs are standard tools for measuring testosterone levels; however, there is evidence that IAs lack accuracy and precision for quantifying low concentrations. Most chemiluminescent IAs overestimate their concentration, especially below 100ng/dL. The procedures that use LC-MSMS have an adequate lower quantification limit and proper accuracy and precision. We found no specific evidence in patients with PC who underwent castration. LC-MSMS is the appropriate method for quantifying low serum testosterone concentrations. We need to define the level of castration with this method and the optimal level related to better progression of the disease. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U.

    Full Text Available Abstract Background Tacrolimus (FK506 is associated with renal fibrosis in long-term use. Mycophenolatemofetil (MMF can also inhibit or attenuate the progression of renal fibrosis. This study aimed to determine the different effects of FK506 and MMF on fibrosis-associated genes in the kidney in rats that underwent chronic allograft nephropathy (CAN. Methods Fisher (F344 kidneys were orthotopically transplanted into Lewis rat recipients. All recipients were given Cyclosporin A (CsA 10 mg/kg-1.d-1 × 10 day and were then randomly divided into three oral treatment groups (n = 9 in each group: (1 the vehicle group was given vehicle orally; (2 the FK506 group was given 0.15 mg/kg-1.d-1 FK506; and (3 the MMF group was given 20 mg/kg-1.d-1 MMF. At 4, 8, and 12 weeks post-transplantation, serum creatinine (SCr, collagen deposition, Connective tissue growth factor (CTGF, alpha smooth muscle actin (α-SMA and E-cadherin expressions were determined and hematoxylin-eosin (HE and Periodic acid-Schiff (PAS stains were performed. Results Renal function progressively deteriorated and showed typical CAN morphology in the vehicle and FK506 groups, while SCr and inflammatory infiltration (Banff score showed a significant decrease in the MMF group after 8 weeks post-transplantation compared with those in the other groups (p α-SMA in the MMF group were significantly reduced, and the down-regulated expression of E-cadherin was abated (p  Conclusions MMF showed favorable effects on renal interstitial fibrosis, thus efficiently retarding the progression of CAN.

  9. Twelve-year cyclic surging episode at Donjek Glacier in Yukon, Canada

    Surge-type glaciers exhibit several-fold to orders-of-magnitude speed-up during the short active phase, resulting in km-scale terminus advance. Although there are many surge-type glaciers near the border of Alaska and the Yukon, the generation mechanisms remain uncertain because of limited and few continuous observations. To better understand the surge dynamics and predict the next event, it is essential to examine the entire surge cycles. Here we use Landsat optical imageries to reveal the long-term evolutions, and report three surging episodes at Donjek Glacier in Yukon, Canada. Using the Landsat images, we found three surging events in 1989, 2001, and 2013. In the 2001 event, the surface speed significantly increased by up to 4.5 m/d; during the quiescent phases it was ~0.5 m/d at the terminus. While the duration of active phase is about 4~5 and 2~3 year in the 2001 and 2013 events, the period in the 1989 event is unclear because of the lack of high temporal resolution data. Remarkably, the surging area is limited to the ~20-km section from the terminus instead of the entire glacier. Moreover, we examined the terminus area changes from 1975 to 2014. Although the area has been secularly decreasing probably due to the tread of global warming, it has also revealed four significant fluctuations during the nearly forty years. Comparing the speed and the area changes, the three speed-up events correspond to the terminus area fluctuations with a few time lags. It turns out that the surge event has been quite regularly repeating every twelve years. Although the behavior is rather similar to that in Svalbard glaciers in terms of maximum speed and unclear initiation season, the recurrence interval is much shorter than other nearby surges. Considering that the surge events seem to have initiated around significantly narrower area than upstream, the strong valley constriction may control the regularity as well as the twelve-year recurrence time.

    Objectives To more precisely examine regional and subregional microstructural brain changes associated with preterm birth. Study design We obtained brain volumes from 29 preterm children, age 12 years, with no ultrasound scanning evidence of intraventricular hemorrhage or cystic periventricular leukomalacia in the newborn period, and 22 age- and sex-matched term control subjects. Results Preterm male subjects demonstrated significantly lower white matter volumes in bilateral cingulum, corpus callosum, corticospinal tract, prefrontal cortex, superior and inferior longitudinal fasciculi compared with term male subjects. Gray matter volumes in prefrontal cortex, basal ganglia, and temporal lobe also were significantly reduced in preterm male subjects. Brain volumes of preterm female subjects were not significantly different from those of term female control subjects. Voxel-based morphometry results were not correlated with perinatal variables or cognitive outcome. Higher maternal education was associated with higher cognitive performance in preterm male subjects. Conclusions Preterm male children continue to demonstrate abnormal neurodevelopment at 12 years of age. However, brain morphology in preterm female children may no longer differ from that of term female children. The neurodevelopmental abnormalities we detected in preterm male subjects appear to be relatively diffuse, involving multiple neural systems. The relationship between aberrant neurodevelopment and perinatal variables may be mediated by genetic factors, environmental factors, or both reflected in maternal education level. PMID:18346506

The grammar rules complied by some grammarians will be focused on and induced in a fuller account of the survey, aiming simply at a common- sense justification of traditional sentence analysis. Subject, a familiar grammatical term, is one of the most basic to thetraditional of grammatical analysis. It reports the concept of the subject and its history conducted with learners of English who are involved in making further English programme in the education with deep grammar explorations. Both the teachers and the students face many problems in this area, which need to be made clear and definite.

    Full Text Available Metastatic involvement of gastrointestinal tract from breast cancer is a rare event. We report the case of a 61-year-old woman presenting with bowel obstruction, related to metastasis of a primary breast cancer she had 12 years earlier (a triple-negative invasive ductal carcinoma treated with surgery and chemotherapy. Bowel obstruction was caused by a 20-centimeter tumor in the jejunum, involving also the transverse colon. The patient underwent en bloc resection of tumor with jejunum and transverse bowel segment and received adjuvant chemotherapy with carboplatin and paclitaxel. Twenty months later, she was alive without disease recurrence.

    To evaluate the incidence of Y-chromosome microdeletions in individuals born from vasectomized fathers who underwent vasectomy reversal or in vitro fertilization with sperm retrieval by epididymal aspiration (percutaneous epididymal sperm aspiration). A case-control study comprising male children of couples in which the man had been previously vasectomized and chose vasectomy reversal (n=31) or in vitro fertilization with sperm retrieval by percutaneous epididymal sperm aspiration (n=30) to conceive new children, and a Control Group of male children of fertile men who had programmed vasectomies (n=60). Y-chromosome microdeletions research was performed by polymerase chain reaction on fathers and children, evaluating 20 regions of the chromosome. The results showed no Y-chromosome microdeletions in any of the studied subjects. The incidence of Y-chromosome microdeletions in individuals born from vasectomized fathers who underwent vasectomy reversal or in vitro fertilization with spermatozoa recovered by percutaneous epididymal sperm aspiration did not differ between the groups, and there was no difference between control subjects born from natural pregnancies or population incidence in fertile men. We found no association considering microdeletions in the azoospermia factor region of the Y chromosome and assisted reproduction. We also found no correlation between these Y-chromosome microdeletions and vasectomies, which suggests that the assisted reproduction techniques do not increase the incidence of Y-chromosome microdeletions.

    Building on the classic depiction of the progression from a diatom to a dinoflagellate bloom as a function of nutrients and turbulence, known as the "Margalef mandala", a new conceptual model or mandala is presented here. The new mandala maps twelve response or effects traits, or environmental characteristics, related to different phytoplankton functional types: (1) relative preference for chemically reduced vs chemically oxidized forms of nitrogen; (2) relative availability of inorganic nitrogen and phosphorus; (3) adaptation to high vs low light and the tendency to be autotrophic vs mixotrophic; (4) cell motility; (5) environmental turbulence; (6) pigmentation quality; (7) temperature; (8) cell size; (9) relative growth rate; (10) relative production of bioactive compounds such as toxins or reactive oxygen species (ROS); (11) r vs K strategy; and (12) fate of the production in terms of grazing. The new mandala serves to highlight the differences and trade-offs between traits and/or environmental conditions, and illustrates some traits tend to track each other, a concept that may be helpful in trait-based modeling approaches and in understanding environmental factors associated with harmful algal blooms. It is hoped that this new mandala captures some of our recent insight into phytoplankton physiology and functional traits, and has contemporary relevance in light of anthropogenic changes in nutrient form and ratio.

    Full Text Available Abstract Background The fibrinogen-like (FBG domain consists of approximately 200 amino acid residues, which has high sequence similarity to the C-terminal halves of fibrinogen β and γ chains. Fibrinogen-related proteins (FREPs containing one or more FBG domains are found universally in vertebrates and invertebrates. In invertebrates, FREPs are involved in immune responses and other aspects of physiology. To understand the complexity of this gene family in Drosophila, we analyzed FREPs in twelve Drosophila species. Results Using the genome data from 12 Drosophila species, we identified FBG domains in each species. The results show that the gene numbers in each species vary from 14 genes up to 43 genes. Using sequence profile analysis, we found that FBG domains have high sequence similarity and are highly conserved throughout. By comparison of structure and sequence conservation, some of the FBG domains in Drosophila melanogaster are predicted to function in recognition of carbohydrates and their derivatives on the surface of microorganisms in innate immunity. Conclusion Sequence and structural analyses show that FREP family across 12 Drosophila species contains conserved FBG domains. Expansion of the FREP families in Drosophila is mainly accounted by a major expansion of FBG domains.

    Full Text Available China has been experiencing severe air pollution and previous studies have mostly focused on megacities and a few hot spot regions. Hefei, the provincial capital city of Anhui province, has a population of near 5 million in its metropolitan area, but its air quality has not been reported in literature. In this study, daily PM10 and visibility data in 2001–2012 were analyzed to investigate the air quality status as well as the twelve-year pollution trends in Hefei. The results reveal that Hefei has been suffering high PM10 pollution and low visibility during the study period. The annual average PM10 concentrations are 2~3 times of the Chinese Ambient Air Quality Standard. PM10 shows fluctuating variation in 2001–2007 and has a slightly decreasing trend after 2008. The annual average visibility range is generally lower than 7 km and shows a worsening trend from 2001 to 2006 followed by an improving trend from 2007 to 2012. Wind speed, precipitation, and relative humidity have negative effects on PM10 concentrations in Hefei, while temperature could positively or negatively affect PM10. The results provide a general understanding of the status and long-term trends of PM10 pollution and visibility in a typical second-tier city in China.

    We present an investigation of twelve candidate transiting planets from Kepler with orbital periods ranging from 34 to 207 days, selected from initial indications that they are small and potentially in the habitable zone (HZ) of their parent stars. The expected Doppler signals are too small to confirm them by demonstrating that their masses are in the planetary regime. Here we verify their planetary nature by validating them statistically using the BLENDER technique, which simulates large numbers of false positives and compares the resulting light curves with the Kepler photometry. This analysis was supplemented with new follow-up observations (high-resolution optical and near-infrared spectroscopy, adaptive optics imaging, and speckle interferometry), as well as an analysis of the flux centroids. For eleven of them (KOI-0571.05, 1422.04, 1422.05, 2529.02, 3255.01, 3284.01, 4005.01, 4087.01, 4622.01, 4742.01, and 4745.01) we show that the likelihood they are true planets is far greater than that of a false po...

    This paper presents the procedures for measuring and analyzing the angular velocity variation of twelve-cylinder diesel engine crankshaft on its free end and on the power-output end. In addition, the paper deals with important aspects of the measurement of crankshaft torsional oscillations. The method is based on digital encoders placed at two distances, and one of them is a sensor not inserted directly on the shaft, i.e. a non-contact method with a toothed disc is used. The principle based on toothed disc is also used to measure the actual camshaft angular velocity of in-line compact high-pressure pump the engine is equipped with, and this paper aims to demonstrate the possibility of measuring the actual angular velocity of any rotating shaft in the engine, on which it is physically possible to mount a toothed disc. The method was created completely independently during long-range development and research tests of V46 family engines. This method is specific for its particular adaptability for use on larger engines with extensive vibrations and torsional oscillations. The main purpose of this paper is a practical contribution to all the more interesting research of the use of engine crankshaft angular velocity as a diagnostic tool for identifying the engine irregular running.

    Full Text Available The aim of the study was to explore the patterns of dental health services access in children under twelve years of age in Peru. Data from 25,285 children under 12 years who participated in the Demographic and Family Health Survey of 2014 were reviewed. An exploratory spatial analysis was performed to project the proportions of children with access to dental health services, according to national regions, type of health service and urban or rural place of residence. The results show that of the total sample, 26.7% had access to dental health services in the last six months, 39.6% belonged to the age group 0-4 years, 40.6% lived in the Andean region and 58.3% lived in urban areas. The regions of Huancavelica, Apurimac, Ayacucho, Lima and Pasco had the highest percentages of access nationwide. In conclusion, there is low access to dental health services in the population under 12 years of age in Peru. The spatial distribution of access to dental health services allows regions to be identified and grouped according to similar access patterns, in order to better focus public health actions.

    Objective The Recovery Management paradigm provides a conceptual framework for the examination of joint impact of a focal treatment and post-treatment service utilization on substance abuse treatment outcomes. We test this framework by examining the interactive effects of a treatment for comorbid PTSD and substance use, Seeking Safety, and post-treatment Twelve-Step Affiliation (TSA) on alcohol and cocaine use. Method Data from 353 women in a six-site, randomized controlled effectiveness trial within the NIDA Clinical Trials Network were analyzed under latent class pattern mixture modeling. LCPMM was used to model variation in Seeking Safety by TSA interaction effects on alcohol and cocaine use. Results Significant reductions in alcohol use among women in Seeking Safety (compared to Health Education) were observed; women in the Seeking Safety condition who followed up with TSA had the greatest reductions over time in alcohol use. Reductions in cocaine use over time were also observed but did not differ between treatment conditions nor were there interactions with post-treatment TSA. Conclusions Findings advance understanding of the complexities for treatment and continuing recovery processes for women with PTSD and SUDs, and further support the chronic disease model of addiction.

    Following the works of Ford et al. and Steffen et al. we derived the transit timing of 1960 Kepler objects of interest (KOIs) using the pre-search data conditioning light curves of the first twelve quarters of the Kepler data. For 721 KOIs with large enough signal-to-noise ratios, we obtained also the duration and depth of each transit. The results are presented as a catalog for the community to use. We derived a few statistics of our results that could be used to indicate significant variations. Including systems found by previous works, we have found 130 KOIs that showed highly significant times of transit variations (TTVs) and 13 that had short-period TTV modulations with small amplitudes. We consider two effects that could cause apparent periodic TTV—the finite sampling of the observations and the interference with the stellar activity, stellar spots in particular. We briefly discuss some statistical aspects of our detected TTVs. We show that the TTV period is correlated with the orbital period of the planet and with the TTV amplitude.

    To provide an estimation of how often peer teaching is applied in medical education, based on reports in the literature and to summarize reasons that support the use of this form of teaching. We surveyed the 2006 medical education literature and categorised reports of peer teaching according to educational distance between students teaching and students taught, group size, and level of formality of the teaching. Subsequently, we analysed the rationales for applying peer teaching. Most reports were published abstracts in either Medical Education's annual feature 'Really Good Stuff' or the AMEE's annual conference proceedings. We identified twelve distinct reasons to apply peer teaching, including 'alleviating faculty teaching burden', 'providing role models for junior students', 'enhancing intrinsic motivation' and 'preparing physicians for their future role as educators'. Peer teaching appears to be practiced often, but many peer teaching reports do not become full length journal articles. We conclude that specifically 'near-peer teaching' appears beneficial for student teachers and learners as well as for the organisation. The analogy of the 'journeyman', as intermediate between 'apprentice' and 'master', with both learning and teaching tasks, is a valuable but yet under-recognized source of education in the medical education continuum.

    The C-banding patterns of twelve weevil species are presented. The obtained results confirm the existence of two groups of species: with a small or large amount of heterochromatin in the karyotype. The first group comprises seven species (Apionidae: Holotrichapion pisi; Curculionidae: Phyllobius urticae, Ph. pyri, Ph. maculicornis, Tanymecus palliatus, Larinodontes turbinatus, Cionus tuberculosus). In weevils with a small amount of heterochromatin, tiny grains on the nucleus in interphase are visible, afterwards in mitotic and meiotic prophase appearing as dark dots. The absence of C-bands does not indicate a lack of heterochromatin but heterochromatic regions are sometimes so small that the condensation is not visible during the cell cycle. The second group comprises five species (Otiorhynchus niger, O. morio, Polydrusus corruscus, Barypeithes chevrolati, Nedyus quadrimaculatus) which possess much larger heteropicnotic parts of chromosomes visible during all nuclear divisions. The species examined have paracentromeric C-bands on autosomes and the sex chromosome X, except for Otiorhynchus niger, which also has an intercalary bands on one pair of autososomes. All the species examined differ in the size of segments of constitutive heterochromatin. The y heterochromosome is dot-like and wholly euchromatic in all the studied species.

    Full Text Available Objective: To evaluate antimicrobial activities in methanolic extracts of twelve sponges collected from the Anambas Islands, Indonesia. Methods: The antibacterial activity of methanolic extracts was tested against two Grampositive bacteria, viz. Bacillus subtilis (ATCC 6633 and Staphylococcus aureus (ATCC 25923, and two Gram-negative bacteria, viz. Eschericia coli (ATCC 25922 and Vibrio anguillarum (ATCC 19264 using the disk diffusion assay. The antifungal activity was similarly tested against Candida albicans (ATCC 10231 and Aspergillus niger (ATCC 16404. The minimum inhibitory concentrations of promising sponges extracts were determined by the microdilution technique. Results: All the sponge species in this study showed antimicrobial activities against at least one of the test strains. Antibacterial activities were observed in 66.7% of the sponges extracts, while 30.0% of the extracts exhibited antifungal activities. Among them, the extracts of the sponges Stylissa massa and Axinyssa sp. were the most active against four tested bacteria and the yeast Candida albicans. The sponge Theonella swinhoei and two species of Xestospongia also displayed significant activities against two fungal pathogens Candida albicans and Aspergillus niger. Conclusions: Antimicrobial activities were demonstrated in extracts from various marine sponges collected from the Anambas Islands, Indonesia. The most promising sponges among them were Stylissa massa and Axinyssa sp. This is the first report of antimicrobial activity in extracts of marine sponges from the Indonesian Anambas Islands.

    We present a spectro-photometric survey of 2522 extragalactic globular clusters (GCs) around twelve early-type galaxies, nine of which have not been published previously. Combining space-based and multi-colour wide field ground-based imaging, with spectra from the Keck DEIMOS instrument, we obtain an average of 160 GC radial velocities per galaxy, with a high velocity precision of 15 km/s per GC. After studying the photometric properties of the GC systems, such as their spatial and colour distributions, we focus on the kinematics of metal-poor (blue) and metal-rich (red) GC subpopulations to an average distance of ~8 effective radii from the galaxy centre. Our results show that for some systems the bimodality in GC colour is also present in GC kinematics. The kinematics of the red GC subpopulations are strongly coupled with the host galaxy stellar kinematics. The blue GC subpopulations are more dominated by random motions, especially in the outer regions, and decoupled from the red GCs. Peculiar GC kinematic ...

    Full Text Available Thousands of whole-genome and whole-proteome sequences have been made available through advances in sequencing technology, and sequences of millions more organisms will become available in the coming years. This wealth of genetic information will provide numerous opportunities to enhance our understanding of these organisms including a greater understanding of relationships among species. Researchers have used 16S rRNA and other gene sequences to study the evolutionary origins of bacteria, but these strategies do not provide insight into the sharing of genes among bacteria via horizontal transfer. In this work we use an open source software program called pClust to cluster proteins from the complete proteomes of twelve species of Alphaproteobacteria and generate a dendrogram from the resulting orthologous protein clusters. We compare the results with dendrograms constructed using the 16S rRNA gene and multiple sequence alignment of seven housekeeping genes. Analysis of the whole proteomes of these pathogens grouped Rickettsia typhi with three other animal pathogens whereas conventional sequence analysis failed to group these pathogens together. We conclude that whole-proteome analysis can give insight into relationships among species beyond their phylogeny, perhaps reflecting the effects of horizontal gene transfer and potentially providing insight into the functions of shared genes by means of shared phenotypes.

    Full Text Available The incidence and survival of lipolytic organisms in domestic wastewater and receiving stream were monitored over 12 months. The average total bacterial count in the wastewater samples reduced in April and November by 24.2% and 41.6% respectively. There was also a reduction of 42.3% and 60.1% in the load in the receiving stream in August and July. Subsequently, at 5m downstream from the entry of the wastewater the microbial load reduced in March (19.2% and June (19.2%. However, the occurrence of coliforms was more affected in the months of May (53% to July (87.2%. At 5m and 10m downstream the coliform population reduced by 27.9% and 30.1% respectively. Of the twelve (12 bacterial isolates obtained at the exit of the wastewater into the receiving stream, only four (4 were found to possess lipolytic activity. These include the species of Enterococcus, Klebsiella, Pseudomonas and Staphylococcus. There was no significant difference in the amount of nutrients found in the domestic wastewater and receiving stream during the months. This paper also discusses the implication of disposing large amounts of wastewater effluents into the receiving water and the need to remedy and minimize the overall impact of such pollution on the environment.

    The evolution of knowledge and technology in recent decades has brought profound changes in science policy, not only in the countries but also in the supranational organizations. It has been necessary, therefore, to adapt the scientific institutions to new models in order to achieve a greater and better communication between them and the political counterparts responsible for defining the general framework of relations between science and society. The Federationon of Scientific Societies of Spain (COSCE, Confederación de Sociedades Científicas de España) was founded in October 2003 to respond to the urgent need to interact with the political institutions and foster a better orientation in the process of making decisions about the science policy. Currently COSCE consists of over 70 Spanish scientific societies and more than 40,000 scientists. During its twelve years of active life, COSCE has developed an intense work of awareness of the real situation of science in Spain by launching several initiatives (some of which have joined other organizations) or by joining initiatives proposed from other groups related to science both at the Spanish level and at the European and non-European scenarios.

    The ecological conversion efficiencies in twelve species of fish in the Yellow Sea Ecosystem, i.e., anchovy ( Engraulis japonicus), rednose anchovy ( Thrissa kammalensis), chub mackerel ( Scomber japonicus), halfbeak ( Hyporhamphus sajori), gizzard shad ( Konosirus punctatus), sand lance ( Ammodytes personatus), red seabream ( Pagrus major), black porgy ( Acanthopagrus schlegeli), black rockfish ( Sebastes schlegeli), finespot goby ( Chaeturichthys stigmatias), tiger puffer ( Takifugu rubripes), and fat greenling ( Hexagrammos otakii), were estimated through experiments conducted either in situ or in a laboratory. The ecological conversion efficiencies were significantly different among these species. As indicated, the food conversion efficiencies and the energy conversion efficiencies varied from 12.9% to 42.1% and from 12.7% to 43.0%, respectively. Water temperature and ration level are the main factors influencing the ecological conversion efficiencies of marine fish. The higher conversion efficiency of a given species in a natural ecosystem is acquired only under the moderate environment conditions. A negative relationship between ecological conversion efficiency and trophic level among ten species was observed. Such a relationship indicates that the ecological efficiency in the upper trophic levels would increase after fishing down marine food web in the Yellow Sea ecosystem.

    Chlorine is the most widely used carcass sanitizer in poultry processing in the USA. The objective of this study was to determine the effects of varying concentrations of organic matter on the susceptibility of twelve most prevalent poultry-associated Salmonella serotypes (MPPSTs) to chlorine. To mimic the microenvironment of the water used for immersion chilling, we manipulated organic matter contamination levels in pre-chilled (pH∼6, T∼4 °C) chlorinated (50 ppm) water using varying concentrations (0, 1, 2, 3, 4, and 5%) of chicken-meat-extract (CME) produced from frozen chicken carcasses. This CME-based in vitro model was challenged with ∼1 × 10(5) CFUs of each MPPST isolate and the bacterial survival was tested at 5, 30, 60 and 90 min post-challenge. In this model, the decimal reduction time (D90-values) of each MPPST was linearly correlated with the concentration of CME. Significant inter-serotype differences in the D90-values were observed. The results show that the pH, concentration of total- and free-chlorine were also linearly correlated with the presence of CME in a concentration-dependent manner. The findings of this study indicate that the serotype and the levels of organic matter contamination significantly influence Salmonella survival and that both variables should be included in models that predict effectiveness of chlorine treatment in immersion chilling.

    In the course of achieving abstinence from alcohol, longstanding members of Alcoholics Anonymous (AA) typically experience a change in their addiction-related attitudes and behaviors. These changes are reflective of physiologically grounded mechanisms which can be investigated within the disciplines of social and cognitive neuroscience. This article is designed to examine recent findings associated with these disciplines that may shed light on the mechanisms underlying this change. Literature review and hypothesis development. Pertinent aspects of the neural impact of drugs of abuse are summarized. After this, research regarding specific brain sites, elucidated primarily by imaging techniques, is reviewed relative to the following: Mirroring and mentalizing are described in relation to experimentally modeled studies on empathy and mutuality, which may parallel the experiences of social interaction and influence on AA members. Integration and retrieval of memories acquired in a setting like AA are described, and are related to studies on storytelling, models of self-schema development, and value formation. A model for ascription to a Higher Power is presented. The phenomena associated with AA reflect greater complexity than the empirical studies on which this article is based, and certainly require further elucidation. Despite this substantial limitation in currently available findings, there is heuristic value in considering the relationship between the brain-based and clinical phenomena described here. There are opportunities for the study of neuroscientific correlates of Twelve-Step-based recovery, and these can potentially enhance our understanding of related clinical phenomena. © American Academy of Addiction Psychiatry.

  15. Deathly silence and apocalyptic noise: Observations on the soundscape of the Book of the Twelve

    2010-03-01

    Full Text Available This paper proposes a reading of the Book of the Twelve (used interchangeably with �Twelve� and �Book� for convenience that concentrates on the sound that is included in the description of the world of the text. Three onomatopoeic devices are singled out. First, the mourning cry h�y is considered. This interjection is used differently in several of the writings: in Amos (5:18; 6:1 the prophet cries out in compassion with the addressees. By contrast, in Nahum 3:1 and Habakkuk 2:6�19, h�y is uttered in a mood of mockery. In Zechariah 2:10 a third, joyful h�y is used. It appears that the different usages cohere nicely with the overall structure of the Book of the Twelve. Secondly, the interjection has likewise shows different usages. In Amos 6:10 and 8:3, it simulates the last breath of Israelites dying when the land is devastated. By contrast, in Habakkuk 2:20, Zephaniah 1:7 and Zechariah 2:17, the addressees are directed to be silent before YHWH. This command should be perceived as an act of reverence. Again, the sequence of the occurrences coheres with the overall structure of the Book of the Twelve. Of special relevance is that the last three instances build a frame around the Babylonian exile, which lies between Zephaniah and Haggai. The third example is the phrase ham�n�m, ham�n�m in Joel 4:14. The author employs an irregular double plural to construe this place as the loudest spot (�apocalyptic noise� within the Twelve.Setu sa go tiba le modumo wa aphokhaliptiki: Ditemogo ka medumo ya Puku ya ba LesomepediPampiri ye e �i�inya go balwa ga Puku ya ba Lesomepedi (yeo e ka nogo bit�wa �Lesomepedi� goba �Puku� go bebofat�a ditaba ka go gatelela modumo wo o lego ka gare ga tlhaloso ya lefase la go tswala dingwalo t�e.

    We report new results on the conformal properties of an important strongly coupled gauge theory, a building block of composite Higgs models beyond the Standard Model. With twelve massless fermions in the fundamental representation of the SU(3) color gauge group, an infrared fixed point (IRFP) of the β -function was recently reported in the theory [A. Cheng, A. Hasenfratz, Y. Liu, G. Petropoulos, and D. Schaich, J. High Energy Phys. 05 (2014) 137] with uncertainty in the location of the critical gauge coupling inside the narrow [6.0 fixed point and scale invariance in the theory with model-building implications. Using the exact same renormalization scheme as the previous study, we show that no fixed point of the β -function exists in the reported interval. Our findings eliminate the only seemingly credible evidence for conformal fixed point and scale invariance in the Nf=12 model whose infrared properties remain unresolved. The implications of the recently completed 5-loop QCD β -function for arbitrary flavor number are discussed with respect to our work.

  17. Twelve tips for creating trigger images for problem-based learning cases.

    Science.gov (United States)

    Azer, Samy A

    2007-03-01

    A trigger is the starting point of problem-based learning (PBL) cases. It is usually in the form of 5-6 text lines that provide the key information about the main character (usually the patient), including 3-4 of patient's presenting problems. In addition to the trigger text, most programs using PBL include a visual trigger. This might be in the form of a single image, a series of images, a video clip, a cartoon, or even one of the patient's investigation results (e.g. chest X-ray, pathology report, or urine sample analysis). The main educational objectives of the trigger image are as follows: (1) to introduce the patient to the students; (2) to enhance students' observation skills; (3) to provide them with new information to add to the cues obtained from the trigger text; and (4) to stimulate students to ask questions as they develop their enquiry plan. When planned and delivered effectively, trigger images should be engaging and stimulate group discussion. Understanding the educational objectives of using trigger images and choosing appropriate images are the keys for constructing successful PBL cases. These twelve tips highlight the key steps in the successful creation of trigger images.

    Background Transmyocardial laser revascularization (TMLR) has been used in the treatment of patients with end-stage coronary artery disease (CAD) since 1990. The aim of this study was to evaluate the long-term effectiveness of TMLR in patients with diffuse CAD.Methods Ninety-four consecutive patients underwent TMLR in one center from July 1997 to December 2000. The follow-up data of these patients were obtained through face-to-face, mail questionnaires, or telephone interviews in July 2004 and December 2004. Four cases failed to respond. Mean follow-up time was (5.5±1.0) years.Results Mean Canadian Cardiovascular Society (CCS) angina scores of TMLR patients were 3.1±0.8 at baseline,1.7±0.9 at 1 year (P<0.05), 1.7±0.9 at 3 years (P<0.05), and 1.9±0.9 at 5 years (P<0.05). At an average of 5 years, 69%of the patients had ≥ 1 angina class reduction, mean NYHA class level (1.9±0.9) ameliorated compared to the baseline (2.5±0.7, P<0.001), the rate of re-hospitalization was 2.7 times/person. Kaplan-Meier survival rate was 87% at 1 year,69% at 3 years and 64% at 5 years. The causes of death were attributed more to heart failure (58.9%) and myocardial infraction (14.7%) after TMLR. The patients with no angina relief, or who died after TMLR, had a higher percentage of preoperative unstable anginas or prior myocardial infraction compared to the survivors. The assorted shapes of myocardial laser channels were detected in some patients by the color Doppler velocity technique.Conclusions TMLR provided a long-term improvement in the quality of life, including CCS angina class or NYHA heart functional class for about 70% of Chinese patients with severely disabling angina pectoris. The various myocardial laser channels would always be visible after TMLR. 5-years after TMLR as a sole therapy, the survival rate of the patients was 64%.

    Objective: To establish the appropriateness of malaria case management at health facility level in four districts in Zambia. Methods: This study was a retrospective evaluation of the quality of malaria case management at health facilities in four districts conveniently sampled to represent both urban and rural settings in different epidemiological zones and health facility coverage. The review period was from January to December 2008. The sample included twelve lower level health facilities from four districts. The Pearson Chi-square test was used to identify characteristics which affected the quality of case management.Results:Out of 4891 suspected malaria cases recorded at the 12 health facilities, more than 80% of the patients had a temperature taken to establish their fever status. About 67% (CI95 66.1-68.7) were tested for parasitemia by either rapid diagnostic test or microscopy, whereas the remaining 22.5% (CI95 21.3.1-23.7) were not subjected to any malaria test. Of the 2247 malaria cases reported (complicated and uncomplicated), 71% were parasitologically confirmed while 29% were clinically diagnosed (unconfirmed). About 56% (CI95 53.9-58.1) of the malaria cases reported were treated with artemether-lumefantrine (AL), 35% (CI95 33.1-37.0) with sulphadoxine-pyrimethamine, 8% (CI95 6.9-9.2) with quinine and 1% did not receive any anti-malarial. Approximately 30% of patients WHO were found negative for malaria parasites were still prescribed an anti-malarial, contrary to the guidelines. There were marked inter-district variations in the proportion of patients in WHOm a diagnostic tool was used, and in the choice of anti-malarials for the treatment of malaria confirmed cases. Association between health worker characteristics and quality of case malaria management showed that nurses performed better than environmental health technicians and clinical officers on the decision whether to use the rapid diagnostic test or not.

    During the past twelve years, NASA's Fermi Gamma-ray Space Telescope has supported a wide range of Education and Public Outreach (E/PO) activities, targeting K-14 students and the general public. The purpose of the Fermi E/PO program is to increase student and public understanding of the science of the high-energy Universe, through inspiring, engaging and educational activities linked to the mission’s science objectives. The E/PO program has additional more general goals, including increasing the diversity of students in the Science, Technology, Engineering and Mathematics (STEM) pipeline, and increasing public awareness and understanding of Fermi science and technology. Fermi's multi-faceted E/PO program includes elements in each major outcome category: ● Higher Education: Fermi E/PO promotes STEM careers through the use of NASA data including research experiences for students and teachers (Global Telescope Network), education through STEM curriculum development projects (Cosmology curriculum) and through enrichment activities (Large Area Telescope simulator). ● Elementary and Secondary education: Fermi E/PO links the science objectives of the Fermi mission to well-tested, customer-focused and NASA-approved standards-aligned classroom materials (Black Hole Resources, Active Galaxy Education Unit and Pop-up book, TOPS guides, Supernova Education Unit). These materials have been distributed through (Educator Ambassador and on-line) teacher training workshops and through programs involving under-represented students (after-school clubs and Astro 4 Girls). ● Informal education and public outreach: Fermi E/PO engages the public in sharing the experience of exploration and discovery through high-leverage multi-media experiences (Black Holes planetarium and PBS NOVA shows), through popular websites (Gamma-ray Burst Skymap, Epo's Chronicles), social media (Facebook, MySpace), interactive web-based activities (Space Mysteries, Einstein@Home) and activities by

    To determine the peripheral refraction of children with different types of ametropias and to evaluate the relationship between central refractive changes, baseline relative peripheral refraction (RPR) and changes in RPR over a 12-month monitoring period. Cycloplegic central and peripheral refraction were performed biannually on the right eyes of children aged 6-9 for 12 months, using an open-view autorefractor. Peripheral refraction were measured along 10°, 20° and 30° from central fixation in both nasal and temporal fields. Refractive data were transposed into M, J0 and J45 vectors for analyses. RPR was determined by subtracting the central measurement from each peripheral measurement. Hyperopic eyes showed relative peripheral myopia while myopic eyes had relative hyperopia across the central 60° horizontal field at baseline. Emmetropic eyes had relative myopia within but showed relative hyperopia beyond the central 30° field. However, there was no significant correlation between central refractive changes and baseline RPR or between changes in central refraction and RPR over twelve months in any refractive groups. Correlations between changes in PR and central myopic shift were found mainly in the nasal field in different groups. In the subgroup analysis on the initially emmetropic and the initially myopic groups, the subgroups with faster myopic progression did not have significantly different RPR from the subgroups with slower progression. The RPR pattern of the initially emmetropic and the initially myopic groups became more asymmetric at the end of the study period with a larger increase in relative hyperopia in the temporal field. RPR patterns were different among hyperopic, emmetropic and myopic eyes. However, baseline RPR and changes in RPR cannot predict changes in central refraction over time. Our results did not provide evidence to support the hypothesis of RPR as a causative factor for myopic central refractive changes in children. Ophthalmic

    Calculations using ab initio Hartree-Fock and Density Functional theories, the latter employing the B3LYP functional, in combination with a number of large standard basis sets ranging from 6-31G** to cc-pVDZ, have been performed on a series of ten and twelve vertex closo-carborane isomer species. Results obtained for optimized structural parameters and molecular properties are presented for 1,2-, 1,6- and 1,10-C{sub 2}B{sub 8}H{sub 10} and 1,2-, 1,7- and 1,12-C{sub 2}B{sub 10}H{sub 12} and compared, where possible, with both earlier theoretical data and experiment. Irrespective of the model chemistry chosen, the para-isomer in each class of carborane cluster is found to be the most stable species, corresponding to a structure in which the cage carbon atoms are positioned at diametrically opposed ends of the respective polyhedron. Boron-hydrogen and carbon-hydrogen bond lengths are found to change little on going from isomers of one particular cage size to another, supporting analogous conclusions previously established for small closo-carborane cages possessing five, six and seven vertices. The calculated vibrational spectra of the isomers of both decacarborane and dodecacarborane are seen to be similar to each other and reflect a high degree of rigidity within each cluster. Key polyhedral skeletal breathing modes along with characteristic boron-hydrogen and carbon-hydrogen stretching frequencies are identified in the spectra and compared with experiment. Thermochemical data relating to each species are also analyzed.

    Trace levels of residual antibiotics in drinking water may threaten public health and become a serious problem in modern society. In this work, we investigated the degradation of twelve sulfonamides (SAs) at environmentally relevant trace level concentrations by three different methods: ultraviolet (UV) photolysis, peroxymonosulfate (PMS) oxidation, and UV-activated PMS (UV/PMS). Sulfaguanidine, sulfadiazine, sulfamerazine, sulfamethazine, sulfathiazole, sulfamethoxydiazine, and sulfadimethoxine were be effectively removed by direct UV photolysis and PMS oxidation. However, sulfanilamide, sulfamethizole, sulfamethoxazole, sulfisoxazole, and sulfachloropyridazine were not completely degraded, despite prolonging the UV irradiation time to 30min or increasing the PMS concentration to 5.0mg·L(-1). UV/PMS provided more thorough elimination of SAs, as demonstrated by the complete removal of 200ng·L(-1) of all SAs within 5min at an initial PMS concentration of 1.0mg·L(-1). UV/PMS promoted SA decomposition more efficiently than UV photolysis or PMS oxidation alone. Bicarbonate concentration and pH had a negligible effect on SA degradation by UV/PMS. However, humic acid retarded the process. Removal of 200ng·L(-1) of each SA from a sample of sand-filtered effluent from a drinking water treatment plant (DWTPs) was quickly and completely achieved by UV/PMS. Meanwhile, about 41% of the total organic carbon (TOC) was eliminated. Scavenging experiments showed that sulfate radical (SO4(-)) was the predominant species involved in the degradation. It is concluded that UV/PMS is a rapid and efficient method for removing trace-level SAs from drinking water. Copyright © 2016 Elsevier B.V. All rights reserved.

  7. A survey of innovation through duplication in the reduced genomes of twelve parasites.

    Full Text Available We characterize the prevalence, distribution, divergence, and putative functions of detectable two-copy paralogs and segmental duplications in the Apicomplexa, a phylum of parasitic protists. Apicomplexans are mostly obligate intracellular parasites responsible for human and animal diseases (e.g. malaria and toxoplasmosis. Gene loss is a major force in the phylum. Genomes are small and protein-encoding gene repertoires are reduced. Despite this genomic streamlining, duplications and gene family amplifications are present. The potential for innovation introduced by duplications is of particular interest. We compared genomes of twelve apicomplexans across four lineages and used orthology and genome cartography to map distributions of duplications against genome architectures. Segmental duplications appear limited to five species. Where present, they correspond to regions enriched for multi-copy and species-specific genes, pointing toward roles in adaptation and innovation. We found a phylum-wide association of duplications with dynamic chromosome regions and syntenic breakpoints. Trends in the distribution of duplicated genes indicate that recent, species-specific duplicates are often tandem while most others have been dispersed by genome rearrangements. These trends show a relationship between genome architecture and gene duplication. Functional analysis reveals: proteases, which are vital to a parasitic lifecycle, to be prominent in putative recent duplications; a pair of paralogous genes in Toxoplasma gondii previously shown to produce the rate-limiting step in dopamine synthesis in mammalian cells, a possible link to the modification of host behavior; and phylum-wide differences in expression and subcellular localization, indicative of modes of divergence. We have uncovered trends in multiple modes of duplicate divergence including sequence, intron content, expression, subcellular localization, and functions of putative recent duplicates that

    Recent findings have reemphasized the importance of epistasis, or gene-gene interactions, as a contributing factor to the unexplained heritability of obesity. Network-based methods such as statistical epistasis networks (SEN), present an intuitive framework to address the computational challenge of studying pairwise interactions between thousands of genetic variants. In this study, we aimed to analyze pairwise interactions that are associated with Body Mass Index (BMI) between SNPs from twelve genes robustly associated with obesity (BDNF, ETV5, FAIM2, FTO, GNPDA2, KCTD15, MC4R, MTCH2, NEGR1, SEC16B, SH2B1, and TMEM18). We used information gain measures to identify all SNP-SNP interactions among and between these genes that were related to obesity (BMI > 30 kg/m(2)) within the Framingham Heart Study Cohort; interactions exceeding a certain threshold were used to build an SEN. We also quantified whether interactions tend to occur more between SNPs from the same gene (dyadicity) or between SNPs from different genes (heterophilicity). We identified a highly connected SEN of 709 SNPs and 1241 SNP-SNP interactions. Combining the SEN framework with dyadicity and heterophilicity analyses, we found 1 dyadic gene (TMEM18, P-value = 0.047) and 3 heterophilic genes (KCTD15, P-value = 0.045; SH2B1, P-value = 0.003; and TMEM18, P-value = 0.001). We also identified a lncRNA SNP (rs4358154) as a key node within the SEN using multiple network measures. This study presents an analytical framework to characterize the global landscape of genetic interactions from genome-wide arrays and also to discover nodes of potential biological significance within the identified network.

    We assessed the thermal environment of eight recently built low-energy houses and twelve conventional Finnish houses. We monitored living room, bedroom and outdoor air temperatures and room air relative humidity from June 2012 to September 2013. Perceived thermal environment was evaluated using a questionnaire survey during the heating, cooling and interim seasons. We compared the measured and perceived thermal environments of the low-energy and conventional houses. The mean air temperature was 22.8 °C (21.9-23.8 °C) in the low-energy houses, and 23.3 °C (21.4-26.5 °C) in the conventional houses during the summer (1. June 2013-31. August 2013). In the winter (1. December 2012-28. February 2013), the mean air temperature was 21.3 °C (19.8-22.5 °C) in the low-energy houses, and 21.6 °C (18.1-26.4 °C) in the conventional houses. The variation of the air temperature was less in the low-energy houses than that in the conventional houses. In addition, the occupants were on average slightly more satisfied with the indoor environment in the low-energy houses. However, there was no statistically significant difference between the mean air temperature and relative humidity of the low-energy and conventional houses. Our measurements and surveys showed that a good thermal environment can be achieved in both types of houses.

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

    Lazar, R

    2001-09-01

    In this article, the author traces the history of the concepts of subject, subjectivity, and intersubjectivity in different psychoanalytic theories in the last decades. She argues that the uniqueness of these concepts and their different implications were not emphasized enough. The author discusses the various implications and contexts of the concept of subject in psychoanalytic theory proper and to relate as to: (1). The need to distinguish between the concepts of subject and subjectivity; (2). The mutual interdependence of the subject and his subjectivity and the intersubjective domain (both in the development of the individual and in theoretical thought pertaining to it). Her point of departure is from the position of the subject as a free creature, the centrality of the experiencing individual, from his/her perspective--the subject in the first person. She tries to explain the paradox implicit in the experiential dimension, the place of the other as participant, as both negating and recognizing--the subject in the third person. She suggests the interdependency of the first-person experience of subjectivity on the intersubjective dimension.

    To determine the prevalence of pathologic findings in asymptomatic knees of marathon runners before and after a competition in comparison with physically active subjects. To compare the diagnostic performance of cartilage-dedicated magnetic resonance imaging (MRI) sequences at 3.0 T. Ten marathon runners underwent 3.0 T MRI 2-3 days before and after competition. Twelve physically active asymptomatic subjects not performing long-distance running were examined as controls. Pathologic condition was assessed with the whole-organ magnetic resonance imaging score (WORMS). Cartilage abnormalities and bone marrow edema pattern (BMEP) were quantified. Visualization of cartilage pathology was assessed with intermediate-weighted fast spin-echo (IM-w FSE), fast imaging employing steady-state acquisition (FIESTA) and T1-weighted three-dimensional (3D) high-spatial-resolution volumetric fat-suppressed spoiled gradient-echo (SPGR) MRI sequences. Eight of ten marathon runners and 7/12 controls showed knee abnormality. Slightly more and larger cartilage abnormalities, and BMEP, in marathon runners yielded higher but not significantly different WORMS (P > 0.05) than in controls. Running a single marathon did not alter MR findings substantially. Cartilage abnormalities were best visualized with IM-w FSE images (P < 0.05). A high prevalence of knee abnormalities was found in marathon runners and also in active subjects participating in other recreational sports. IM-w FSE sequences delineated more cartilage MR imaging abnormalities than did FIESTA and SPGR sequences. (orig.)

    The establishment of prognostic models for Crohn's disease [CD] is highly desirable, as they have the potential to guide physicians in the decision-making process concerning therapeutic choices, thus improving patients' health and quality of life. Our aim was to derive models for disabling CD and reoperation based solely on clinical/demographic data. A multicentric and retrospectively enrolled cohort of CD patients, subject to early surgery or immunosuppression, was analysed in order to build Bayesian network models and risk matrices. The final results were validated internally and with a multicentric and prospectively enrolled cohort. The derivation cohort included a total of 489 CD patients [64% with disabling disease and 18% who needed reoperation], while the validation cohort included 129 CD patients with similar outcome proportions. The Bayesian models achieved an area under the curve of 78% for disabling disease and 86% for reoperation. Age at diagnosis, perianal disease, disease aggressiveness and early therapeutic decisions were found to be significant factors, and were used to construct user-friendly matrices depicting the probability of each outcome in patients with various combinations of these factors. The matrices exhibit good performance for the most important criteria: disabling disease positive post-test odds = 8.00 [2.72-23.44] and reoperation negative post-test odds = 0.02 [0.00-0.11]. Clinical and demographical risk factors for disabling CD and reoperation were determined and their impact was quantified by means of risk matrices, which are applicable as bedside clinical tools that can help physicians during therapeutic decisions in early disease management.

    Full Text Available Jordan imports rice from different countries without any quality preferences. Twelve varieties of cooked rice marketed in Jordan were analyzed. The content per serving of these varieties were computed for energy, protein, carbohydrates, fat, calcium, sodium, potassium, magnesium, manganese, copper, iron and phosphorous. The protein content per serving found to range from 0.49 g for La Cigala rice to 6.2 g for Harvest rice. The fat content for all rice brands was less than 0.37 g per serving. The energy content ranged from 172.12 g/serving for Basmati rice to 212.25 g/serving for Sun White rice. Generally, all rice varieties contain significant amounts of minerals per serving. Ruzzana found to contain the highest level of calcium (38.2 mg/serving and Amber the lowest calcium content (6.7 mg/serving. Magnesium content found to range from 5.7 mg/serving for Royal Umberella rice to 16.3 mg/serving for Ruzzana rice. Consumption of one serving of Harvest cooked rice will cover 13.5% of the daily requirement of protein for females and 11.1% for males. Manganese content of one serving of Harvest, Sun White, Abu bent and La Cigala will cover 22.2% of the daily requirements for females and 14.7% for males, while consumption of one of Basmati, Sos rice or Amber will cover only 11.1% and 8.75 of requirement for females and males respectively.

    2002-04-01

    The American Association for the Advancement of Science and the National Research Council have called for the creation of a scientifically literate populace and introduced science standards and guidelines to direct this process. Science education in traditional school settings plays a key role in reaching this goal, but individuals over their lifetimes will have more exposure to science ideas through informal science experiences such as visits to museums and through diverse media sources. The purpose of this study was to explore the role museums play in this journey to science literacy. This qualitative collective case study examined the experience of 12 children and their families in a children's museum as they interacted with an exhibit designed along the tenets of constructivist theory to introduce children to ideas of science. Twelve children and their families were videotaped interacting with a model of a watershed that included the stream, surrounding land, gravel, and dam building and erosion abatement manipulatives. Children were interviewed to ascertain their stream-related ideas and conceptual understanding prior to and after using the exhibit. Parents completed demographic and post-exhibit experience questionnaires. Two museum staff members who played key roles in the development of the exhibit and surrounding gallery were also interviewed. Individual and cross-case analyses were done to describe the experience of each child and family, and to elucidate the commonalities of these experiences to describe the phenomenon of using a constructivist-based science exhibit. Results of the study indicate (1) the type of experience children and families had at the exhibit depended on child and parent interactions and roles each assumed, and (2) experience with the exhibit encouraged children to think more deeply about water topics, past experiences, and ideas they had previously constructed. Implications of this research include (1) parents should engage children

    2009-12-01

    Full Text Available It has been well documented that for heart transplant recipients (HTrecipient post transplantation exercise capacity does not exceed 60% of healthy age-matched controls. Few studies have been undertaken to determine the cause of exercise limitations following heart transplantation (HT for an elite athlete. Participant was a 39 year old elite male cyclist who suffered an acute myocardial infarction after a cycling race and received a heart transplant (HT four months later. Six weeks prior to his AMI fitness testing was completed and a predicted VO2max of 58 mL·kg-1·min-1 and HRmax of 171 bpm was achieved. The participant underwent maximal exercise testing 6 and 12 months post transplant to determine exercise limitations. His results 6 and 12 months post transplant were a VO2max of 33.8 and 44.2 mL·kg-1·min-1 respectively, and a HR max that was 97% and 96% of HRmax measured. The participant showed an increase in both HRmax and VO2max 12 months post HT compared to previous testing. Results suggest that the limiting factors to exercise following HT are likely due to peripheral function, which became diminished as a result accumulated from 4 months of congestive heart failure, the strain of HT, and immunosuppressive therapy leading up to the exercise testing. Lifestyle before HT and a more aggressive approach to HT recovery should be considered necessary in the improvement of peripheral functioning following HT

    Full Text Available The aim of the current study was to identify the Rugby game- related statistics that discriminated between winning and losing teams in IRB and S12 close games. Archival data reported to game-related statistics from 120 IRB games and 204 Super Twelve games played between 2003 and 2006. Afterwards, a cluster analysis was conducted to establish, according to game final score differences, three different match groups. Only the close games group was selected for further analysis (IRB n = 64 under 15 points difference and Super Twelve n = 95 under 11 points difference. An analysis to the structure coefficients (SC obtained through a discriminant analysis allowed to identify the most powerful game-related statistics in discriminating between winning and losing teams. The discriminant functions were statistically significant for Super Twelve games (Chi-square = 33.8, p < 0.01, but not for IRB games (Chi- square = 9.4, p = n.s.. In the first case, winners and losers were discriminated by possessions kicked (SC = 0.48, tackles made (SC = 0.45, rucks and pass (SC = -0.40, passes completed (SC = 0. 39, mauls won (SC = -0.36, turnovers won (SC = -0.33, kicks to touch (SC = 0.32 and errors made (SC = -0.32. The minus sign denotes higher values in losing teams. Rugby game-related statistics were able to discriminate between winners and losers in Super Twelve close games and suggest that a kicking based game supported by an effective defensive structure is more likely to win matches than a possession based one

    The visual acuity of twelve multi-handicapped, mentally retarded subjects, diagnosed as deaf-blind, was measured on two occasions with the Teller Acuity Cards (TAC). Eight subjects scored above the criterion for legally blind and the results of six of these indicated various degrees of poor to approaching-normal eyesight. To evaluate high-level vision four subjects were tested with the Fagan Test, assessing visual recognition memory for faces subsequent to familiarization with the preferential looking technique. The results for three subjects showed evidence for perceptual recognition. It is concluded that TAC combined with the Fagan Test may detect perceptual capacities unnoticed by clinical observation.

    Full Text Available Considering that the root structure of the Brazilian genera belonging to the Catasetinae subtribe is poorly known, we describe the roots of twelve representatives from this subtribe. For anatomical analysis, the roots were fixed in FAA 50, preserved in ethanol 70% and sectioned at its medium region using razor blades. The sections were stained with 0.05% astra blue and safranin and mounted in glycerin. For the identification of starch we used Lugol's solution; for lignin, floroglucin chloridric; for lipids, Sudan III, and for flavanoids, potassium hydroxide. The relevant aspects were registered using a digital camera joined with an Olympus microspope (BX51 model. The structural similarities of all roots support the placement of the subtribe Catasetinae into the monophyletic tribe Cymbidieae. Some root features are restricted to one or two taxa and can be useful in the systematics of the subtribe. For example, the occurrence of flavonoidic crystals characterizes the genera Catasetum and Cychnodes, and the number of the velamen layers and the shape of the epivelamen cells are useful to confirm the taxonomic position of Clowesia amazonica. The presence of velamen and flavonoidic crystals was interpreted as an adaptation to the epiphytic habit.Considerando que a estrutura das raízes de gêneros brasileiros pertencentes à subtribo Catasetinae é pouco conhecida, descrevemos as raízes de doze representantes desta subtribo. Para análise anatômica, as raízes foram fixadas em FAA 50, preservadas em álcool 70% e seccionadas na sua região média usando lâminas de barbear. Os cortes foram corados com astra blue e Safrablau 0,05% e montados em glicerina. Para a identificação do amido, utilizou-se a solução de Lugol; da lignina, floroglucina clorídrica, dos lipídios, Sudan III e dos flavonóides, hidróxido de potássio.

    Full Text Available Introduction : Fifty percent of cases of peripheral artery disease are caused by chronic total occlusion (CTO of the superficial femoral artery (SFA. Ten–fifteen percent of percutaneous SFA recanalization procedures are unsuccessful. In those cases the retrograde technique can increase the success rate of the procedure, but the long-term follow-up of such procedures is still unknown. Aim : To assess the efficacy and clinical outcomes during long-term follow-up after retrograde recanalization of the SFA. Material and methods: We included patients after at least one unsuccessful percutaneous antegrade recanalization of the SFA. Patients were evaluated for the procedural and clinical follow-up of mean time 13.9 months. Results: The study included 17 patients (7 females, 10 males who underwent percutaneous retrograde recanalization of the SFA from June 2011 to June 2015. The mean age of patients was 63 ±7 years. Retrograde puncture of the distal SFA was successful in all cases. A retrograde procedure was performed immediately after antegrade failure in 4 (23.5% patients and after a previously failed attempt in 13 (76.5% patients. The procedure was successful in 15 (88.2% patients, and unsuccessful in 2 (11.8% patients. Periprocedural complications included 1 peripheral distal embolization (successfully treated with aspiration thrombectomy, 1 bleeding event from the puncture site and 7 puncture site hematomas. During follow-up the all-cause mortality rate was 5.8% (1 patient, non-cardiac death. The primary patency rate at 12 months was 88.2% and secondary patency 100%. Conclusions : The retrograde SFA puncture seems to be a safe and successful technique for CTO recanalization and is associated with a low rate of perioperative and long-term follow-up complications.

    To evaluate the short-term efficacy and safety of intravitreal bevacizumab for the treatment of retinal angiomatous proliferation. Seventeen eyes from 16 patients with newly diagnosed retinal angiomatous proliferation underwent intravitreal injections of bevacizumab, 1.25 mg. The patients were scheduled for three monthly bevacizumab injections. Early Treatment of Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity, central macular thickness on optical coherence tomography, and fluorescein angiographic findings were examined before and after treatment. Patients were followed-up for 12 months. The mean best-corrected visual acuity (+/- standard deviation [SD]) at baseline was 39.53 (+/-10.40) letters (Snellen equivalent: 20/42). At 12 months after treatment the mean best-corrected visual acuity (+/-SD) improved significantly (P = 0.0000001) to 47.88 (+/-11.78) letters (Snellen equivalent: 20/28). Best-corrected visual acuity improved 3 ETDRS lines or more in 3 (17.65%) of 17 treated eyes, 14 (82.35%) eyes were stable, and 15 (88.23%) eyes gained 1 or more ETDRS lines. The mean central macular thickness (+/-SD) at baseline was 297 (+/-60.72) microm. At 12 months after treatment, the mean central macular thickness (+/-SD) reduced significantly (P = 0.00001) to 237 (+/-28.80) microm. At the 12-month follow-up, absence of fluorescein leakage was demonstrated in 14 (82%) of 17 treated eyes. No ocular or systemic adverse effects from treatment were encountered. The 12-month results of intravitreal bevacizumab for retinal angiomatous proliferation are very promising with no apparent short-term safety concerns. Treated eyes had a significant functional and anatomical improvement. Further studies will be needed to better determine long-term efficacy and safety.

    It has been well documented that for heart transplant recipients (HTrecipient) post transplantation exercise capacity does not exceed 60% of healthy age-matched controls. Few studies have been undertaken to determine the cause of exercise limitations following heart transplantation (HT) for an elite athlete. Participant was a 39 year old elite male cyclist who suffered an acute myocardial infarction after a cycling race and received a heart transplant (HT) four months later. Six weeks prior to his AMI fitness testing was completed and a predicted VO2max of 58 mL·kg(-1)·min(-1) and HRmax of 171 bpm was achieved. The participant underwent maximal exercise testing 6 and 12 months post transplant to determine exercise limitations. His results 6 and 12 months post transplant were a VO2max of 33.8 and 44.2 mL·kg(-1)·min(-1) respectively, and a HR max that was 97% and 96% of HRmax measured. The participant showed an increase in both HRmax and VO2max 12 months post HT compared to previous testing. Results suggest that the limiting factors to exercise following HT are likely due to peripheral function, which became diminished as a result accumulated from 4 months of congestive heart failure, the strain of HT, and immunosuppressive therapy leading up to the exercise testing. Lifestyle before HT and a more aggressive approach to HT recovery should be considered necessary in the improvement of peripheral functioning following HT. Key pointsPhysical work capacity following heart transplantation is not limited by cardiac denervation.Heart transplant rehabilitation should focus efforts on endothelial and muscular limitations.

    The Amplatzer Amulet (St. Jude Medical, Minneapolis, MN, USA) is a second gen-eration Amplatzer device for left atrial appendage (LAA) occlusion (LAAO) for stroke prophylaxis in patients with atrial fibrillation. This research sought to assess the clinical performance of the Amplatzer Amulet device and in follow up for 12 months. In this single-center registry patients with atrial fibrillation and contraindication to oral anticoagulation underwent LAAO with the Amplatzer Amulet device. Follow-up was performed before discharge, by transesophageal echocardiography (TEE) after 6 weeks and telephone interview after 3, 6 and 12 months. Between October 2014 and August 2015 50 patients (76.1 ± 8.3 years; 30 male) were en-rolled. Procedural success was achieved in 49 (98%) patients. Major periprocedural adverse events were observed in 4 (8%) of patients: 1 device embolization, 2 pericardial effusions requiring pericardiocente-sis and 1 prolonged hospital stay due to retropharyngeal hematoma from the TEE probe. Follow-up TEE was available in 38 of 50 patients showing complete LAA sealing in all. 2 device-related thrombi were also documented. At 12-month follow-up 7 patients had died unrelated to the device. Ischemic stroke occurred in 3 patients. According to neurological examination two were classified as microangiopathic and not cardio-embolic. The other one could not be classified. Bleeding complications (5 minor, 3 major) were documented in 8 patients. Although minimizing procedure-related complications remains challenging, LAAO with the Amplatzer Amulet device showed high procedural success and excellent LAA sealing.

    Full Text Available The contribution of modern science to the progress of civilization is immeasurable. Even its tendency toward exclusive concentration on the objective world has had salutary effects of great value. Modern science has wiped away much that was merely superstitious or speculative. Its rejection of unfounded opinions and prejudices has helped the thinking mind question conventional beliefs, shed preferences and prejudices, and challenge established authority. But modern systems thinking inherited from natural science is the suppression of the subjective dimension of reality. Many complex systems are an attempt to define and represent all subjective experience in physical terms. The modern man has a bias towards objectivity. The powerful influence of sense impressions on his mind and thinking makes him ignore the subjective experience and consider only objective facts as a valid, legitimate and representation of reality. Observing objective factors that are physical is easier than observing subjective factors that are subtle. The mechanistic view of reality has led to the rejection of the role of the individual in social development as insignificant. The individuals determine the development of society. Their social power has its roots both in subjective factors and objective factors. Economy, politics, society, and culture are inseparable dimensions of a single integrated reality. Subject and object constitute an integrated whole. The mind sees them as separate and independent. Or it views one as completely subordinate to the other. Unbiased approach to the study of all human experiences may prove that subject and object are interdependent dimensions or elements of reality.

    Psychological problems are common in cancer patients. For the purpose of planning psycho-oncological interventions and services tailored to the specific needs of different cancer patient populations, it is necessary to know to what extent psychological problems meet the criteria of mental disorders. The purpose of this study was to estimate the 12-month and lifetime prevalence rates of mental disorders in cancer patients. A representative sample of patients with different tumour entities and tumour stages (n = 2,141) in outpatient, inpatient and rehabilitation settings underwent the standardized computer-assisted Composite International Diagnostic Interview for mental disorders adapted for cancer patients (CIDI-O). The overall 12-month prevalence for any mental disorder was 39.4% (95% CI: 37.3-41.5), that for anxiety disorders was 15.8% (95% CI: 14.4-17.4), 12.5% (95% CI: 11.3-14.0) for mood disorders, 9.5% (95% CI: 8.3-10.9) for somatoform disorders, 7.3% (95% CI: 6.2-8.5) for nicotine dependence, 3.7% (95% CI: 3.0-4.6) for disorders due to general medical condition, and 1.1% (95% CI: 0.7-1.6) for alcohol abuse or dependence. Lifetime prevalence for any mental disorder was 56.3% (95% CI 54.1-58.6), that for anxiety disorders was 24.1% (95% CI: 22.3-25.9), 20.5% (95% CI: 18.9-22.3) for mood disorders, 19.9% (95% CI: 18.3-21.7) for somatoform disorders, 18.2% (95% CI: 16.6-20.0) for nicotine dependence, 6.4% (95% CI: 5.4-7.6) for alcohol abuse or dependence, 4.6% (95% CI: 3.8-5.6) for disorders due to general medical condition, and 0.2% (95% CI: 0.1-0.6) for eating disorders. Mental disorders are highly prevalent in cancer patients, indicating the need for provision of continuous psycho-oncological support from inpatient to outpatient care, leading to an appropriate allocation of direct personnel and other resources. © 2016 S.

  1. Subjective Rationalizability in Hypergames

    Directory of Open Access Journals (Sweden)

    Yasuo Sasaki

    2014-01-01

    Full Text Available A new solution concept for hypergames called subjective rationalizability is proposed. Hypergame theory is a game theoretical framework that deals with agents who may misperceive game structures and explicitly takes into account hierarchy of perceptions, that is, an agent’s view about another agent’s view and so on. An action of an agent is called subjectively rationalizable when the agent thinks it can be a best response to the other’s choices, each of which the agent thinks each agent thinks is a best response to the other’s choices, and so on. Then it is proved that subjective rationalizability is equivalent to the standard notion of rationalizability under a condition called inside common knowledge. The result makes the new solution concept a practical tool in hypergame analyses. Theoretically, it is characterized as such a concept that provides the precise implication, that is, predicted outcomes, of a given hypergame structure.

    Full Text Available The purpose of this article is to analyze the relationship of man with death and its deployment in subjectivity and in aging. With this intent, we first present a brief history of the vision of death over time and after an analysis of the process of aging and dying according to the logic of biopolitical management. With death and old age increasingly distant from the horizons of life, subjectivity has been weakened. Thus, incorporating these aspects as part of existence constitutes one of the challenges to the thought as well as to the building of the self.

    This paper deals with the notions of "subjectivity," "intersubjectivity," and "community" from several different points of view that include subjective and intersubjective agency, a sense of community, the community as a social institution, and the idea of social justice. The context of these considerations can be found in the Community-Social-Psychological approach to social action as it is often practiced in Latin America. A review of these themes is considered important because different models of community intervention and practice may lead to different expressions of community interaction.

    Full Text Available OBJECTIVES: While respiratory distress is accepted as the only indication for diaphragmatic plication surgery, sleep disorders have been underestimated. In this study, we aimed to detect the sleep disorders that accompany diaphragm pathologies. Specifically, the association of obstructive sleep apnea syndrome with diaphragm eventration and diaphragm paralysis was evaluated. METHODS: This study was performed in Süreyyapasa Chest Diseases and Thoracic Surgery Training and Research Hospital between 2014-2016. All patients had symptoms of obstructive sleep apnea (snoring and/or cessation of breath during sleep and/or daytime sleepiness and underwent diaphragmatic plication via video-assisted mini-thoracotomy. Additionally, all patients underwent pre- and postoperative full-night polysomnography. Pre- and postoperative clinical findings, polysomnography results, Epworth sleepiness scale scores and pulmonary function test results were compared. RESULTS: Twelve patients (7 males with a mean age of 48 (range, 27-60 years and a mean body mass index of 25 (range, 20-30 kg/m2 were included in the study. Preoperative polysomnography showed obstructive sleep apnea syndrome in 9 of the 12 patients (75%, while 3 of the patients (25% were regarded as normal. Postoperatively, patient complaints, apnea hypopnea indices, Epworth sleepiness scale scores and pulmonary function test results all demonstrated remarkable improvement. CONCLUSION: All patients suffering from diaphragm pathologies with symptoms should undergo polysomnography, and patients diagnosed with obstructive sleep apnea syndrome should be operated on. In this way, long-term comorbidities of sleep disorders may be prevented.

    AbstractObjectiveTo determine the factors associated with change in bilirubin concentration 12 weeks after the initiation of an atazanavir (ATV)-containing antiretroviral regimen.MethodsWe performed a retrospective case note review of all patients prescribed ATV between January 2004 and October 2007 in a cohort of HIV infected subjects. Data collected included baseline demographics, hepatitis B and C serology, current antiretroviral therapy, baseline and week 12 routine bloods. The primary endpoint was the change in bilirubin concentration at 12 weeks after start of ATV. Multvariable linear regression was performed to assess the relationships between the change in bilirubin and variables of interest. Results: Eighty-three ATV-treated patients were included in the analysis of whom 46 (60.5%) were hepatitis C antibody positive. The median (interquartile range) change in bilirubin by week 12 was 16 (4, 22) umol\\/L; only 1 patient developed grade 4 hyperbilirubinaemia at week 12. After controlling for baseline bilirubin levels, HCV seropositivity and baseline ALP were associated with a smaller change in bilirubin over the 12 weeks with a trend towards lower increases in those receiving tenofovir. Sensitivity analyses reported similar associations with methadone use and injection drug use, when these variables replaced HCV sero-positivity in the model. Conclusion: Patients with hepatitis C co-infection experience smaller changes in bilirubin upon exposure to ATV. Although the underlying mechanism for this association remains unclear, these data support the safe use of this drug in this patient setting. Further research into the clinical predictors of ATV-related hyperbilirubinaemia is warranted.

    The Spent Nuclear Fuel (SNF) Project will transfer metallic SNF from the Hanford 105 K-East and 105 K-West Basins to safe interim storage in the Canister Storage Building in the 200 Area. The initial basis for design, fabrication, installation, and operation of the fuel removal systems was that the basin leak rates which could result from a postulated accident condition would not be excessive relative to reasonable recovery operations. However, an additional potential K Basin water leak path is through the K Basin drain valves. Three twelve-inch drain valves are located in the main basin bays along the north wall. The sumps containing the valves are filled with concrete which covers the drain valve body. Visual observations suggest that only the valve's bonnet and stem are exposed above the basin concrete floor. It was recognized, however, that damage of the drain valve bonnet or stem during a seismic initiating event could provide a potential K Basin water leak path. The objectives of this activity are to: (1) evaluate the risk of damaging the three twelve-inch drain valves located along the north wall of the main basin from a seismic initiating event, and (2) determine the associated potential leak rate from a damaged valve.

  20. [Subjective cognition in schizophrenia].

    2017-02-01

    Given the extent, magnitude and functional significance of the neurocognitive deficits of schizophrenia, growing attention has been paid recently to patients' self-awareness of their own deficits. Thus far, the literature has shown either that patients fail to recognize their cognitive deficits or that the association between subjective and objective cognition is weak in schizophrenia. The reasons for this lack of consistency remain unexplained but may have to do, among others, with the influence of potential confounding clinical variables and the choice of the scale used to measure self-awareness of cognitive deficits. In the current study, we sought to examine the relationships between subjective and objective cognitive performance in schizophrenia, while controlling for the influence of sociodemographic and psychiatric variables. Eighty-two patients with a schizophrenia-spectrum disorder (DSM-IV criteria) were recruited. Patients' subjective cognitive complaints were evaluated with the Subjective Scale to Investigate Cognition in Schizophrenia (SSTICS), the most frequently used scale to measure self-awareness of cognitive deficits in schizophrenia. Neurocognition was evaluated with working memory, planning and visual learning tasks taken from Cambridge Neuropsychological Tests Automated Battery. The Stroop Color-Word test was also administered. Psychiatric symptoms were evaluated with the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia. The relationships between subjective and objective cognition were evaluated with multivariate hierarchic linear regression analyses, taking into consideration potential confounders such as sociodemographic and psychiatric variables. Finally, a factor analysis of the SSTICS was performed. For the SSTICS total score, the regression analysis produced a model including two predictors, namely visual learning and Stoop interference performance, explaining a moderate portion of the variance

    A vital factor conditioning the usage of the pulmonary perfusion (Q) scan in the evaluation of patients suspected of pulmonary embolism is the prevalence of abnormal Q scans in subjects free of cardiopulmonary disease. Because this prevalence has not been well defined, we performed Q scans in 80 nonsmoking subjects 18 to 29 yr of age having no known active cardiopulmonary disease. Each subject underwent a history, physical examination, electrocardiogram, spirometry, and PA chest roentgenogram, followed by a 6-view Q scan. Two subjects in whom a Q defect was suspected underwent a /sup 133/Xe equilibrium-washout ventilation (V) scan. All Q scans were interpreted blindly and independently by 2 experienced readers. Seventy-nine of the 80 Q scans were read as normal. No subject demonstrated a lobar or segmental defect. One of the 80 subjects, who had a mild pectus excavatum, had a left upper lobe subsegmental defect, which was not seen on the V scan. Based on the statistical analysis of these data, no more than 3.68% of normal nonsmoking persons in this age group may have a lobar or segmental Q scan defect and no more than 6.77% may have a subsegmental defect (with 95% confidence). Therefore, our study indicated that Q scan defects, particularly lobar or segmental, are rarely present among normal nonsmokers in this age group.

    Clofibrate, a widely used hypolipidaemic agent was given for twelve weeks to ten subjects with hypertriglyceridaemia. Its effect on lipoprotein-lipids and caeruloplasmin, IgA, IgM, alpha2-microglobulin and transferrin was assessed by comparing analyses at 4, 8 and 12 weeks on therapy with the means of values at two weeks before and at the start of treatment. The normal variation in plasma proteins was assessed in six healthy volunteers during the same period of time. On clofibrate, very low density lipoprotein (VLDL) cholesterol and triglyceride concentrations fell, but the concentrations of cholesterol in low density (LDL) and high density (HDL) lipoproteins showed no consistent change. Caeruloplasmin and IgM concentrations decreased significantly, IgA showed a limited falls (significant only at 8 weeks) and alpha2-macroglobulin did not change. The concentration of transferrin increased on therapy. No relationships were found between the falls in VLDL-lipid concentrations and the alterations in other plasma proteins. No significant variation occurred in the concentrations of lipids or proteins in the normal subjects during the period of study. The results indicate that clofibrate exerts general effects on protein metabolism.

    Statins and renin-angiotensin system (RAS) blockers are key drugs for treating patients with an acute myocardial infarction (AMI). This study was designed to show the association between treatment with statins or RAS blockers and clinical outcomes and the efficacy of two drug combination therapies in patients with ischemic heart failure (IHF) who underwent revascularization for an AMI. A total of 804 AMI patients with a left ventricular ejection fraction <40% who undertook percutaneous coronary interventions (PCI) were analyzed using the Korea Acute Myocardial Infarction Registry (KAMIR). They were divided into four groups according to the use of medications [Group I: combination of statin and RAS blocker (n=611), Group II: statin alone (n=112), Group III: RAS blocker alone (n=53), Group IV: neither treatment (n=28)]. The cumulative incidence of major adverse cardiac and cerebrovascular events (MACCEs) and independent predictors of MACCEs were investigated. Over a median follow-up study of nearly 1 year, MACCEs had occurred in 48 patients (7.9%) in Group I, 16 patients (14.3%) in Group II, 3 patients (5.7%) in Group III, 7 patients (21.4%) in Group IV (p=0.013). Groups using RAS blocker (Group I and III) showed better clinical outcomes compared with the other groups. By multivariate analysis, use of RAS blockers was the most powerful independent predictor of MACCEs in patients with IHF who underwent PCI (odds ratio 0.469, 95% confidence interval 0.285-0.772; p=0.003), but statin therapy was not found to be an independent predictor. The use of RAS blockers, but not statins, was associated with better clinical outcomes in patients with IHF who underwent PCI.

    Background Myocardial revascularization surgery is the best treatment for dyalitic patients with multivessel coronary disease. However, the procedure still has high morbidity and mortality. The use of extracorporeal circulation (ECC) can have a negative impact on the in-hospital outcomes of these patients. Objectives To evaluate the differences between the techniques with ECC and without ECC during the in-hospital course of dialytic patients who underwent surgical myocardial revascularization. Methods Unicentric study on 102 consecutive, unselected dialytic patients, who underwent myocardial revascularization surgery in a tertiary university hospital from 2007 to 2014. Results Sixty-three patients underwent surgery with ECC and 39 without ECC. A high prevalence of cardiovascular risk factors was found in both groups, without statistically significant difference between them. The group "without ECC" had greater number of revascularizations (2.4 vs. 1.7; p <0.0001) and increased need for blood components (77.7% vs. 25.6%; p <0.0001) and inotropic support (82.5% vs 35.8%; p <0.0001). In the postoperative course, the group "without ECC" required less vasoactive drugs, (61.5% vs. 82.5%; p = 0.0340) and shorter time of mechanical ventilation (13.0 hours vs. 36,3 hours, p = 0.0217), had higher extubation rates in the operating room (58.9% vs. 23.8%, p = 0.0006), lower infection rates (7.6% vs. 28.5%; p = 0.0120), and shorter ICU stay (5.2 days vs. 8.1 days; p = 0.0054) as compared with the group with ECC surgery. No difference in mortality was found between the groups. Conclusion Myocardial revascularization with ECC in patients on dialysis resulted in higher morbidity in the perioperative period in comparison with the procedure without ECC, with no difference in mortality though.

    Full Text Available For Plantier, language constitutes reality and is male dominated. Readers of texts, she says, are at a disadvantage because the author imposes a logic that we must accept in order to understand the text. The discourses shaping our social reality have the same effect. Plantier has struggled against individual voices, discourses, and the very fabric of language informed by these discourses. "Subject to Instability" examines the impact on her generic evolution of a changing sense of self, of who her interlocutors are, and of those for whom she is speaking. I argue that her increasing attempt to juggle many different voices destabilizes her "monologic," poetical voice, resulting in a blurring of generic boundaries and eventually the abandonment of poetry. Recognizing that our entry into language is a form of alienation also unsettles Plantier because it undermines the very identity that allows her to speak for others. She concludes that each woman needs to become a Subject in her own right, but she continues to struggle against dominant discourses, modeling "resisting reader" strategies. If she can no longer practice "monologic steadfastness," this does not deter her from attempting to dismantle patriarchal language and striving to make her voice prevail over others.

  15. Twelve positions in a β-lactamase that can expand its substrate spectrum with a single amino acid substitution.

    Hyojeong Yi

    Full Text Available The continuous evolution of β-lactamases resulting in bacterial resistance to β-lactam antibiotics is a major concern in public health, and yet the underlying molecular basis or the pattern of such evolution is largely unknown. We investigated the mechanics of the substrate fspectrum expansion of the class A β-lactamase using PenA of Burkholderia thailandensis as a model. By analyzing 516 mutated enzymes that acquired the ceftazidime-hydrolyzing activity, we found twelve positions with single amino acid substitutions (altogether twenty-nine different substitutions, co-localized at the active-site pocket area. The ceftazidime MIC (minimum inhibitory concentration levels and the relative frequency in the occurrence of substitutions did not correlate well with each other, and the latter appeared be largely influenced by the intrinsic mutational biases present in bacteria. Simulation studies suggested that all substitutions caused a congruent effect, expanding the space in a conserved structure called the omega loop, which in turn increased flexibility at the active site. A second phase of selection, in which the mutants were placed under increased antibiotic pressure, did not result in a second mutation in the coding region, but a mutation that increased gene expression arose in the promoter. This result suggests that the twelve amino acid positions and their specific substitutions in PenA may represent a comprehensive repertoire of the enzyme's adaptability to a new substrate. These mapped substitutions represent a comprehensive set of general mechanical paths to substrate spectrum expansion in class A β-lactamases that all share a functional evolutionary mechanism using common conserved residues.

    Pretest probability of coronary artery disease (CAD) facilitates diagnosis and risk stratification of CAD. Stress myocardial perfusion imaging (MPI) and chronic kidney disease (CKD) are established major predictors of cardiovascular events. However, the role of CKD to assess pretest probability of CAD has been unclear. This study evaluates the role of CKD to assess the predictive value of cardiovascular events under consideration of pretest probability in patients who underwent stress MPI. Patients with no history of CAD underwent stress MPI (n = 310; male = 166; age = 70; CKD = 111; low/intermediate/high pretest probability = 17/194/99) and were followed for 24 months. Cardiovascular events included cardiac death and nonfatal acute coronary syndrome. Cardiovascular events occurred in 15 of the 310 patients (4.8 %), but not in those with low pretest probability which included 2 CKD patients. In patients with intermediate to high pretest probability (n = 293), multivariate Cox regression analysis identified only CKD [hazard ratio (HR) = 4.88; P = 0.022) and summed stress score of stress MPI (HR = 1.50; P probability. In patients with intermediate to high pretest probability, CKD and stress MPI are independent predictors of cardiovascular events considering the pretest probability of CAD in patients with no history of CAD. In assessing pretest probability of CAD, CKD might be an important factor for assessing future cardiovascular prognosis.

    The Forgotten Joint Score (FJS) is a newly developed health-related quality of life (HRQoL) questionnaire designed to evaluate the awareness after total knee arthroplasty (TKA). This study cross-culturally adapted and psychometrically validated a simplified Chinese version of the FJS (SC-FJS). Cross-cultural adaptation was performed according to the internationally recognized guidelines. One-hundred and fifty participants who underwent primary TKA were recruited in this study. Cronbach's α and intra-class correlations were used to determine reliability. Construct validity was analyzed by evaluating the correlations between SC-FJS and the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the short form (36) health survey (SF-36). Each of the 12 items was properly responded and correlated with the total items. SC-FJS had excellent reliability [Cronbach's α = 0.907, intra-class correlation coefficient (ICC) = 0.970, 95% CI 0.959-0.978). Elimination of any one item in all did not result in a value of Cronbach's α of  0.05) correlation with mental subscale of SF-36. SC-FJS demonstrated excellent acceptability, internal consistency, reliability, and construct validity, which can be recommended for patients who underwent joint arthroplasty in Mainland China.

    Iodiated contrast-induced nephropathy (CIN) is a serious complication of contrast-enhanced imaging. The aim of this study was to evaluate the diagnostic sensitivities and specificities of serum cystatin C (sCys C) and serum creatinine (sCr) for CIN and to further investigate difference of the incidence, risk factors, and in-hospital and 3-month prognosis of CIN according to sCys C criteria and sCr criteria. We prospectively evaluated 213 patients who underwent angiography. The sCr and sCys C concentrations were detected before and at 48 hours, 72 hours after the procedure. The incidence, risk factors, and in-hospital and 3-month prognosis of CIN were analyzed. Receiver operating characteristic curve (ROC) analysis was performed for sCr and sCys C 48 hours after procedure. The incidence of CIN was 24.4% (sCys C criteria) and 8% (sCr criteria). Diabetes mellitus, dehydration, and hypoalbuminemia were independent risk factors for CIN. Area under the ROC of sCys C 48 hours after procedure was not superior to sCr (0.715 vs 0.790, P=.178). The mortality of patients with CIN in sCr criteria increased significantly (PC was not superior to sCr for predicting CIN in the patients who underwent angiography. © 2016 Wiley Periodicals, Inc.

    Owing to the increasing population of elderly patients, a large number of patients with degenerative spondylosis are currently being surgically treated. Although basic measures for decreasing postoperative surgical infections (PSIs) are considered, it still remains among the leading causes of morbidity and mortality. The aim of this retrospective analysis is to present possible causes leading to PSI in patients who underwent surgery for lumbar degenerative spondylosis and highlight how it can be avoided to decrease morbidity and mortality. The study included 540 patients who underwent posterior stabilization due to degenerative lumbar stenosis between January 2013 and January 2014. The data before and after surgery was retrieved from the hospital charts. Patients with degenerative lumbar stenosis who were operated upon in this study had >2 levels of laminectomy and facetectomy. For this reason, posterior stabilization was performed for all the patients included in this study. Determining the causes of postoperative infection (PI) following spinal surgeries performed with instrumentation is a struggle. Seventeen different parameters that may be related to PI were evaluated in this study. The presence of systemic diseases, unknown glove perforations, and perioperative blood transfusions were among the parameters that increased the prevalence of PI. Alternatively, prolene sutures, double-layered gloves, and the use of rifampicin Sv (RIS) decreased the incidence of PI. Although the presence of systemic diseases, unnoticed glove perforations, and perioperative blood transfusions increased PIs, prolene suture material, double-layered gloves, and the use of RIS decreased PIs.

    Endometriosis is a complex disease primarily affecting women of reproductive age worldwide. The management goals are to improve the quality of life (QoL), alleviate the symptoms and prevent severe disease. This prospective cohort study was to assess the QoL in women with endometriosis that underwent primary surgery. A pre- and post-operative questionnaire via ED-5Q and general VAS score used for the evaluation for endometrial-like pain such as dysmenorrhoea and dyspareunia. A total of 280 patients underwent intervention; 224 laparoscopically and 56 via laparotomy mostly with stage II disease with ovarian endometriomas. Improvements in dysmenorrhoea pain scores from 5.7 to 4.15 and dyspareunia from 4.05 to 2.17 (p improved; 6.66-4.68 post-operatively (p intervention. There was no correlation between the stage of disease and endometrial pain; (p = .289), method of intervention (p = .290) and usage of post-operative hormonal therapy (p = .632). This study concluded that surgical treatment improved the QoL with added hormonal therapy post-intervention, despite not reaching statistical significance, showed a promising result. Impact statement Surgical intervention does improve the QoL for women with endometriosis however post interventional hormonal therapy is remain inconclusive.

    Full Text Available Abstract Background Training of neuromuscular control has become increasingly important and plays a major role in rehabilitation of subjects with an injury to the anterior cruciate ligament (ACL. Little is known, however, of the influence of this training on knee stiffness during loading. Increased knee stiffness occurs as a loading strategy of ACL-injured subjects and is associated with increased joint contact forces. Increased or altered joint loads contribute to the development of osteoarthritis. The aim of the study was to determine if knee stiffness, defined by changes in knee kinetics and kinematics of gait, step activity and cross-over hop could be reduced through a knee-specific 12-week training programme. Methods A 3-dimensional motion analysis system (VICON and a force plate (AMTI were used to calculate knee kinetics and kinematics before and after 12 weeks of knee-specific training in 12 males recruited from a cohort with ACL injury 16 years earlier. Twelve uninjured males matched for age, sex, BMI and activity level served as a reference group. Self-reported patient-relevant data were obtained by the KOOS questionnaire. Results There were no significant changes in knee stiffness during gait and step activity after training. For the cross-over hop, increased peak knee flexion during landing (from 44 to 48 degrees, p = 0.031 and increased internal knee extensor moment (1.28 to 1.55 Nm/kg, p = 0.017 were seen after training, indicating reduced knee stiffness. The KOOS sport and recreation score improved from 70 to 77 (p = 0.005 and was significantly correlated with the changes in knee flexion during landing for the cross-over hop (r = 0.6, p = 0.039. Conclusion Knee-specific training improved lower extremity kinetics and kinematics, indicating reduced knee stiffness during demanding hop activity. Self-reported sport and recreational function correlated positively with the biomechanical changes supporting a clinical importance of the

    Full Text Available ABSTRACT OBJECTIVE: To correlate spinopelvic balance with the development of degenerative spondylolisthesis and disk herniation. METHODS: This was a descriptive retrospective study that evaluated 60 patients in this hospital, 30 patients with degenerative spondylolisthesis at the L4-L5 level and 30 with herniated disk at the L4-L5 level, all of whom underwent Surgical treatment. RESULTS: Patients with lumbar disk herniation at L4-L5 level had a mean tilt of 8.06, mean slope of 36.93, and mean PI of 45. In patients with degenerative spondylolisthesis at the L4-L5 level, a mean tilt of 22.1, mean slope of 38.3, and mean PI of 61.4 were observed. CONCLUSION: This article reinforces the finding that the high mean tilt and PI are related to the onset of degenerative spondylolisthesis, and also concluded that the same angles, when low, increase the risk for disk herniation.

    Pancreatic cystic lesions (PCLs) are considered precursors of pancreatic cancer. Diabetes mellitus (DM) and obesity are known as risk factors for pancreatic cancer. We investigated the prevalence of PCLs in the general population and the relationship between PCLs and DM/obesity. This cross-sectional analysis included 5296 individuals who underwent a preventive medical examination between October 2006 and June 2013 at our institution. Magnetic resonance imaging, including magnetic resonance cholangiopancreatography, was performed using a 3.0-T system as part of a comprehensive health screening program. We investigated the prevalence and risk factors of PCLs. The prevalence of PCLs was 13.7%, which was increased according to age. Individuals with PCLs were more prone to obesity (body mass index, 24.0 vs 23.7 kg/m [P = 0.015]; waist circumference, 87.4 vs 85.5 cm [P Pancreatic cystic lesions were significantly associated with DM and obesity.

    Research indicates that slow heart rate recovery 1-2 minutes after exercise is a predictor of cardiovascular mortality, sudden mortality as well. It is hardly related to myocardial ischemia; most of all, it is related to impaired activities of the parasympathetic system. The purpose of this study was to assess HRR in subjects after a surgical treatment (percutaneous coronary intervention - PCI) of acute coronary syndromes (ACS), undergoing cardiologic rehabilitation. The study comprised 58 subjects, 42 men and 16 women aged 49-68 (56.8 +/- 7.6) after ACS treated with PCI undergoing cardiologic rehabilitation (stage 2)--group I. The comparative group comprised 34 subjects, 25 men and 9 women aged 46-61 (55.5 +/- 8.9 lat) who were clinically healthy and who underwent a single sub-maximal exercise test--group II. In subjects undergoing rehabilitation, an exercise test was performed twice --before and after stage 2 of rehabilitation. HRR was defined as a difference between the peak heart rate and those after the 1st (HRR1) and 2nd (HRR) minute of recovery. After stationary rehabilitation as a part of stage 2 of cardiologic rehabilitation, HRR2 was 26.3 +/- 10.6/min and was 40.8/min +/- 13.8/min; both these values were not significantly different from values observed in healthy subjects (p > 0.05). Significant increase in HRR1 and HRR2 was observed after the completion of stage 2 of cardiologic rehabilitation in ill subjects (p < 0.05) as compared to initial values. In subjects after ACS treated with PCI, it is observed that HRR changes back to normal values observed in healthy subjects as a result of underwent cardiologic rehabilitation. HRR should become an important factor in assessing effectiveness of conducted cardiologic rehabilitation.

    To evaluate the efficiency and safety of iontophoretic transepithelial corneal crosslinking in pediatric patients with progressive keratoconus underwent general or topical anesthesia in 18 months follow-up. 13 patients (13 eyes) diagnosed with progressive keratoconus underwent corneal CXL with iontophoresis (I-CXL). Riboflavin solution was administered by iontophoresis for 5 min, and then UV-A irradiation (10 mW/cm) was performed for 9 min. Preoperative and post-operative visits at 1, 6, 12, and 18 months assessed the following parameters: uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), slit-lamp biomicroscopy, corneal topography, optical tomography, and pachymetry with Pentacam (Oculus Optikgeräte GmbH, Wetzlar, Germany), endothelial biomicroscopy (Konan Specular Microscope; Konan Medical, Inc., Hyogo, Japan). The paired Student t test was used to compare data during the follow-up. 10 males and 3 females with a mean age of 15.4 ± 1.7 years (range 11-18 years) were included. The results showed a stabilization of the refractive UCVA and BCVA as early as the first post-operative month, with a slight improvement over time. The Kmax remained stable throughout follow-up (p = 0.04). Transepithelial collagen crosslinking by iontophoresis, unlike other transepithelial techniques seems to halt pediatric keratoconus progression over 18 months. This is the second study evaluating CXL with iontophoresis in pediatric patients with progressive keratoconus with 18 months of follow-up using two different ways of anesthesia.

    Objective:To explore the effect of advanced blood pressure control with nifedipine delayed-release tablets on the blood pressure in patients underwent nasal endoscope surgery and its feasibility.Methods:A total of 80 patients who were admitted in ENT department from June, 2012 to June, 2015 for nasal endoscope surgery were included in the study and randomized into the observation group and the control group with 40 cases in each group. The patients in the observation group were given nifedipine delayed-release tablets for advanced blood pressure control before operation, and were given routine blood pressure control during operation; while the patients in the control group were only given blood pressure control during operation. The changes of blood pressure, mean central arterial pressure, and heart rate before anesthesia (T0), after intubation (T1), during operation (T2), extubation when waking (T3), 30 min after extubation (T4), and 3 h after back to wards (T5) in the two groups were compared. The intraoperative situation and the surgical field quality in the two groups were compared.Results: SBP, DBP, and MAP levels at T1-5 in the two groups were significantly lower than those at T0. SBP, DBP, and MAP levels at T2 were significantly lower than those at other timing points, and were gradually recovered after operation, but were significantly lower than those at T0. The effect taking time of blood pressure reducing, intraoperative nitroglycerin dosage, and postoperative wound surface exudation amount in the observation group were significantly less than those in the control group. The surgical field quality scores in the observation group were significantly superior to those in the control group.Conclusions:Advanced blood pressure control with nifedipine delayed-release tablets can stabilize the blood pressure during the perioperative period in patients underwent nasal endoscope surgery, and enhance the surgical field qualities.

    Although the number of elderly increases disproportionately throughout the industrialised nations and intubation-related cardiovascular compromise is associated with hospital mortality, no emergency medicine literature has reported the direction and magnitude of effect of advanced age on post-intubation hypotension. We seek to determine whether advanced age is associated with an increased rate of hypotension at airway management in emergency departments (EDs). We conducted an analysis of a multi-centre prospective observational study of 13 Japanese EDs from April 2010 to March 2012. Inclusion criteria were all adult non-cardiac-arrest patients who underwent emergency intubation. We excluded patients in whom airway management was performed for shock or status asthmaticus as the principal indication. Patients were divided into two groups defined a priori: age ≥ 65 years old (elderly group) and age airway management at 13 EDs. Among these, the database recorded 3,872 intubations (capture rate 96%). Of 1,903 eligible patients, 975 patients were age ≥ 65 years (51%) and 928 patients were age advanced age had an adjusted OR for post-intubation hypotension of 2.6 (95% CI, 1.3-5.6; P = 0.01). In this large multi-centre study of ED patients who underwent emergent airway management, we found that elderly patients have a significantly higher risk of post-intubation hypotension. These data provide implications for the education and practice of ED airway management that may lead to better clinical outcomes and improved patient safety.

    To determine the effect of intracoronary transfer of superparamagnetic iron oxide (SPIO) labeled heme oxygenase-1 (HO-1) overexpressed bone marrow stromal cells (BMSCs) in a porcine myocardial ischemia/reperfusion model. Cell apoptosis was assayed and supernatant cytokine concentrations were measured in BMSCs that underwent hypoxia/reoxygen in vitro. Female mini-swines that underwent 1 h LAD occlusion followed by 1 h reperfusion were randomly allocated to receive intracoronary saline (control), 1 x 10(7) SPIO-labeled BMSCs transfected with pcDNA3.1-Lacz plasmid (Lacz-BMSCs), pcDNA3.1-human HO-1 (HO-1-BMSCs), pcDNA3.1-hHO-1 pretreated with a HO inhibitor, tin protoporphyrin (SnPP, n = 10 each). MRI and postmortem histological analysis were made at 1 week or 3 months thereafter. Post hypoxia/reoxygen in vitro, apoptosis was significantly reduced, supernatant VEGF significantly increased while TNF-alpha and IL-6 significantly reduced in HO-1-BMSCs group compared with Lacz-BMSCs group (all p < 0.05). Myocardial expression of VEGF was significantly higher in HO-1-BMSCs than in Lacz-BMSCs group at 1 week post transplantation (all p < 0.05). Signal voids induced by the SPIO were detected in the peri-infarction region in all BMSC groups at 1 week but not at 3 months post transplantation and the extent of the hypointense signal was the highest in HO-1-BMSCs group, and histological analysis showed that signal voids represented cardiac macrophages that engulfed the SPIO-labeled BMSCs. Pretreatment with SnPP significantly attenuated the beneficial effects of HO-1-BMSCs. Transplantation of HO-1-overexpressed BMSCs significantly enhanced the beneficial effects of BMSCs on improving cardiac function in this model.

    Cardiac output during right-sided heart catheterization is an important variable for patient selection of advanced therapies (cardiac transplantation and left ventricular assist device implantation). The Fick method to determine cardiac output is commonly used and typically uses estimated oxygen consumption (VO2) from 1 of 3 published empirical formulas. However, these estimation equations have not been validated in patients with heart failure and reduced ejection fraction (HFrEF). The objectives of the present study were to determine the accuracy of 3 equations for estimating VO2 compared with direct measurement of VO2 and determine the extent clinically significant error occurred in calculating cardiac output of patients with HFrEF. Breath-by-breath measurements of VO2 from 44 patients who underwent cardiac catheterization (66% men; age, 65 ± 11 years, left ventricular ejection fraction, 22 ± 6%) were compared with the derived estimations of LaFarge and Miettinen, Dehmer et al, and Bergstra et al. Single-sample t tests found only the mean difference between the estimation of LaFarge and Miettinen and the measured VO2 to be nonsignificant (-10.3 ml/min ± 6.2 SE, p = 0.053). Bland-Altman plots demonstrated unacceptably large limits of agreement for all equations. The rate of ≥25% error in the equations by LaFarge and Miettinen, Dehmer et al, and Bergstra et al occurred in 11%, 23%, and 45% of patients, respectively. Misclassification of cardiac index derived from each equation for 2 clinically important classifications: cardiogenic shock-21%, 23%, and 32% and hypoperfusion-16%, 16%, and 25%; respectively. In conclusion, these findings do not support the use of these empiric formulas to estimate the VO2 at rest in patients with HFrEF who underwent right-sided heart catheterization.

  11. Naming the Ethological Subject.

    Benson, Etienne S

    2016-03-01

    Argument In recent decades, through the work of Jane Goodall and other ethologists, the practice of giving personal names to nonhuman animals who are the subjects of scientific research has become associated with claims about animal personhood and scientific objectivity. While critics argue that such naming practices predispose the researcher toward anthropomorphism, supporters suggest that it sensitizes the researcher to individual differences and social relations. Both critics and supporters agree that naming tends to be associated with the recognition of individual animal rights. The history of the naming of research animals since the late nineteenth century shows, however, that the practice has served a variety of purposes, most of which have raised few ethical or epistemological concerns. Names have been used to identify research animals who play dual roles as pets, workers, or patients, to enhance their market value, and to facilitate their identification in the field. The multifaceted history of naming suggests both that the use of personal names by Goodall and others is less of a radical break with previous practices than it might first appear to be and that the use of personal names to recognize the individuality, sentience, or rights of nonhuman animals faces inherent limits and contradictions.

  12. Chronic subjective dizziness.

    2008-10-01

    Chronic subjective dizziness (CSD) is frequent and affects twice as many women as men. Anxiety is a strong predisposing factor. The pathophysiologic concept of this disorder assumes that balance function and emotion share common neurologic pathways, which might explain that the balance disorder can provoke fear and vice versa, giving rise to a problem in perception of space and motion. In anxious patients this can turn into a space and motion phobia, with avoidance behaviour. CSD is a diagnosis based on the hypothesis of an interaction between the vestibular system and the psychiatric sphere. Patients complain of chronic imbalance, worsened by visual motion stimulation, and frequently suffer from anxiety. Vestibular examination reveals no anomalies. We evaluated the incidence and characteristics of CSD in patients referred to our neuro-otology centre (tertiary hospital outpatient clinic). This was a retrospective study of 1552 consecutive patients presenting with vertigo. CSD was diagnosed in 164 patients (female:male=111:53). CSD represents 10.6% of the dizzy patients in our clinic. Psychiatric disorder, mainly anxiety, was found in 79.3% of the cases. Other frequently associated factors were fear of heights and former vestibular lesion (healed). In all, 79.0% of the patients with CSD had poor balance performance on dynamic posturography testing.

    Full Text Available The specific aspects which determined the way some groups of students conducted their work in a university laboratory, made us understand the articulation of these groups´s dynamics, from elements that were beyond the reach of cognition. In more specific terms the conduction and the maintenance of the groups student´s dynamics were explicited based on a intergame between the non conscious strategies, shared anonymously, and the efforts of the individuals in working based on their most objective task. The results and issues we have reached so far, using a reference the work developed by W.R.Bion, with therapeutical groups, gave us the possibility for understanding the dynamics of the student´s experimental work through a new approach that approximates the fields of cognition and subjectivity. This approximation led us to a deeper reflection about the issues which may be involved in the teaching process, particularly in situations which the teacher deals with the class, organised in groups.

    Introduction To establish the skeletal pattern in subjects with malocclusions and temporomandibular disorders (TMD); to assess the relationship between craniofacial skeletal structures and TMD in subjects with malocclusions. Material and methods Sixty-four subjects with malocclusions, over 18 years of age, were included in the study. Temporomandibular disorders were clinically assessed according to the Helkimo Anamnestic Index. Subjects underwent a lateral cephalogram. Subjects were grouped according to the sagittal skeletal pattern (ANB angle) into class I, II and III. Parametric Student tests with equal or unequal variations were used (variations were previously tested with Levene test). Results Twenty-four patients with TMD (experimental sample); 40 patients without TMD (control group); interincisal angle was higher in class I and II (p overjet was larger in experimental subjects; midline shift and Wits appraisal were broader in the experimental group in all three classes. In class III subjects, the SNB angle was higher in the experimental group (p = 0.01). Joint noises followed by reduced mandible mobility, muscular pain and temporomandibular joint (TMJ) pain were the most frequent symptoms in subjects with TMD and malocclusions. Conclusions Temporomandibular joint status is an important factor to consider when planning orthodontic treatment in patients with severe malocclusions; midline shift, large overjet and deep overbite have been associated with signs and symptoms of TMD.

    Highlights: • Screen dominant plants grown in uranium mill tailings soils. • Quantify the content of {sup 232}Th of soil samples from uranium mill tailings. • Quantify the transfer factor, bioconcentration factor and phytoremediation factor. • Screen out the plant species capable of remediating radionuclide contaminated soils. • Guide the reuse of study area in future. - Abstract: The concentrations of thorium ({sup 232}Th) in soil from a uranium mill tailings repository in South China were analyzed. The results showed that all the soil samples were acidic and the concentrations of {sup 232}Th in all the soil samples were more than the natural radionuclide content in soil of China. Through the field investigation, twelve kinds of dominant plants were discovered. The total quantity of {sup 232}Th in the whole plant is highest in rice flat sedge. We also found that Miscanthus floridulus has the greatest transfer factor (TF) for {sup 232}Th, rice flat sedge has the greatest bioconcentration factor (BF) for {sup 232}Th. At the mean time, M. floridulus has the greatest phytoremediation factor (PF) for {sup 232}Th. On the basis of the above conclusions and the definition for hyperaccumulator, rice flat sedge and M. floridulus could be the candidates of phytoremediation for radionuclide {sup 232}Th in the soil.

    The objective of this study was to describe the oral phase of swallowing in individuals with dental malocclusion and to generate data that would contribute to the rehabilitation of those patients. The study was based on the evaluation of the swallowing system through videofluoroscopy on thirty-four children of both genders, aged eight to twelve years old who present with Angle Class II and III dental malocclusions. Thirteen children of similar age and gender presenting normal dental occlusion formed the control group. The results indicated that the oral phase of swallowing is different between individuals with normal occlusion and malocclusion. Dental occlusion types Angle Class II and III did not present a swallowing pattern, independently of the amount of liquid ingested. The swallowing appeared effective in the oral phase of individuals with dental malocclusion, even though adaptations were identified. The outcome, in the absence of a single pattern and the efficiency of the adapted swallowing demonstrates, first a need for additional research investigating orofacial myofunctional treatment for patients with malocclusion and second how such analyses should focus on contributing positively to the rehabilitation of these patients.

    This paper presents the results of the past seven years of experimental investigation and testing done on the two-stage twelve-axis vibration isolation platform for Advanced LIGO gravity waves observatories. This five-ton two-and-half-meter wide system supports more than a 1000 kg of very sensitive equipment. It provides positioning capability and seismic isolation in all directions of translation and rotation. To meet the very stringent requirements of Advanced LIGO, the system must provide more than three orders of magnitude of isolation over a very large bandwidth. It must bring the motion below 10^(-11) m/(Hz)^0.5 at 1 Hz and 10^(-12) m/(Hz)^0.5 at 10 Hz. A prototype of this system has been built in 2006. It has been extensively tested and analyzed during the following two years. This paper shows how the experimental results obtained with the prototype were used to engineer the final design. It highlights how the engineering solutions implemented not only improved the isolation performance but also greatl...

    Full Text Available With the exception of some French-speaking islands, data on tuberculosis (TB in the Caribbean are scarce. In this study, we report a first assessment of genetic diversity of a convenience sample of Mycobacterium tuberculosis strains received from twelve Caribbean territories by spoligotyping and describe their drug-resistance patterns. Of the 480 isolates, 40 (8.3% isolates showed resistance to at least one anti-TB drug. The proportion of drug-resistant strains was significantly higher in The Bahamas (21.4%; P=0.02, and Guyana (27.5%; P<0.0001, while it was significantly lower in Jamaica (2.4%; P=0.03 than in other countries of the present study. Regarding genetic diversity, 104 distinct spoligotype patterns were observed: 49 corresponded to clustered strains (2 to 93 strains per cluster, while 55 remained unclustered among which 16 patterns were not reported previously. Combining the study results with regional data retrieved from the international SITVIT2 database underlined a connection between frequency of certain M. tuberculosis phylogenetic lineages and the language spoken, suggesting historical (colonial and ongoing links (trade, tourism, and migratory flows with European countries with which they shared a common past.

  20. Measuring performance in off-patent drug markets: a methodological framework and empirical evidence from twelve EU Member States.

    Kanavos, Panos

    2014-11-01

    This paper develops a methodological framework to help evaluate the performance of generic pharmaceutical policies post-patent expiry or after loss of exclusivity in non-tendering settings, comprising five indicators (generic availability, time delay to and speed of generic entry, number of generic competitors, price developments, and generic volume share evolution) and proposes a series of metrics to evaluate performance. The paper subsequently tests this framework across twelve EU Member States (MS) by using IMS data on 101 patent expired molecules over the 1998-2010 period. Results indicate that significant variation exists in generic market entry, price competition and generic penetration across the study countries. Size of a geographical market is not a predictor of generic market entry intensity or price decline. Regardless of geographic or product market size, many off patent molecules lack generic competitors two years after loss of exclusivity. The ranges in each of the five proposed indicators suggest, first, that there are numerous factors--including institutional ones--contributing to the success of generic entry, price decline and market penetration and, second, MS should seek a combination of supply and demand-side policies in order to maximise cost-savings from generics. Overall, there seems to be considerable potential for faster generic entry, uptake and greater generic competition, particularly for molecules at the lower end of the market.

    High-resolution infrared spectra (R=50,000) have been obtained for twelve red-giant members of the LMC with the Gemini South 8.3-meter telescope plus Phoenix spectrometer. Quantitative chemical abundances of carbon-12, carbon-13, nitrogen-14, and oxygen-16 were derived from molecular lines of CO, CN, and OH, while sodium, scandium, titanium, and iron abundances were derived from neutral atomic lines. The LMC giants have masses from about 1 to 4 solar masses and span a metallicity range from [Fe/H]= -1.1 to -0.3. The program red giants all show evidence of first dredge-up mixing, with low 12C/13C ratios, and low 12C correlated with high 14N abundances. Comparisons of the oxygen-to-iron ratios in the LMC and the Galaxy indicate that the trend of [O/Fe] versus [Fe/H] in the LMC falls about 0.2 dex below the Galactic trend. Such an offset can be modeled as due to an overall lower rate of supernovae per unit mass in the LMC relative to the Galaxy, as well as a slightly lower ratio of supernovae of type II to super...

    Full Text Available Background: Due to the presence of radiosensitive organs in the abdominopelvic region and increasing the number of requests for CT scan examinations, concerns about increasing radiation doses in patients has been greatly elevated. Therefore, the goal of this study was to determine the absorbed dose of radiosensitive organs and the effective dose in patients underwent abdominopelvic CT scan using ImPACT CT patient dosimetry Calculator (version 1.0.4, Imaging Performance Assessment on Computed Tomography, www.impactscan.org. Methods: This prospective cross-sectional study was conducted in Imam Reza Hospital from November to February 2015 February 2015 in the Imam Reza Hospital, in Urmia, Iran. The demographic and dosimetric information of 100 patients who underwent abdominopelvic CT scan in a 6-slice CT scanner were obtained through the data collection forms. The demographic data of the patients included age, weight, gender, and BMI. The dosimetric parameters included pitch value, CT dose volume index (CTDIvol, dose-length product (DLP, tube voltage, tube current, exposure time, collimation size, scan length, and scan time. To determine the absorbed dose of radiosensitive organs and also the effective dose in patients, ImPACT CT patient dosimetry calculator was used. Results: The results of this study demonstrated that the mean and standard deviation (SD of patients' effective dose in abdominopelvic CT scan was 4.927±0.164 mSv. The bladder in both genders had the greatest mean organ dose, which was 64.71±17.15 mGy for men and 77.56±18.48 mGy for women (P<0.001. Conclusion: The effective dose values of this examination are in the same range as previous studies, as well as International Commission on Radiological Protection (ICRP recommendations. However, the radiation dose from CT scan has the largest contribution to the medical imaging. According to the ALARA principle, it is recommended that the scan parameters, especially mAs, should be

    objective test has only one correct answer, while subjective test has a range of possible answers. Because of this feature, reliability will not be difficult to achieve in the marking of the objective item, while the marking of the subjective items is reliable. On the whole, a good test must contain both subjective and objective test items.

    This study was aimed to investigate the prophylactic effect of CsA, MTX and MMF combined with ATG on graft versus host disease (GVHD) after unrelated donor peripheral blood hematopoietic stem cell transplantation (URD-PBHSCT). 33 patients underwent URD-PBHSCT with unrelated donor of HLA matched or 1 locus mismatched. The clinical data of all cases were retrospectively analyzed. URD-PBHSCT recipients received cyclosporin A+short term MTX+mycophenolate mofetil (MMF)+antithymocyte globulin to prevent GVHD (URD-ATG group), while 13 out of 33 patients were given additionally anti-CD25 antibody (URD-ATG+CD25 group). The results showed that engraftment was successfully achieved in 100% of all patients. In URD-ATG+CD25 group and URD-ATG group, the incidence of aGVHD were 23.07% and 45%, the incidence of cGVHD were 0 and 47.4% respectively. The latter was significantly higher than the former (pMMF+ATG as the prophylaxis of GVHD for UDR-PBSCT is effective. Reducing the dose of ATG may be good for patient in progression status.

    Keratoconus is a corneal disease in which the cornea assumes a conical shape due to an irregular alteration of the internal structure of the corneal tissue and sometimes is progressive, especially in young people. Anatomically, the main signs of keratoconus are thinning of the cornea in its central or paracentral region, usually accompanied by an increase in this part of a high irregular astigmatism, with a consequent loss of vision. Its diagnosis requires a thorough study including the family history, a complete ophthalmologic examination and imaging studies. This diagnosis allows classifying the type of keratoconus, which allow determining options of management, with what it is possible to establish a visual prognosis of each eye. One of the indicators that help in the diagnosis of keratoconus is an inherited familiar propensity. The literature reports an incidence of keratoconus of 11%1 in first-degree relatives of patients with keratoconus. Results suggest an ethnic dependence, which implies that the knowledge of the tendency of keratoconus in the Mexican population is important. In this work, we present the preliminary results of the study realized to a group of relatives of patients who underwent corneal transplant by advanced keratoconus using Orbscan II topographic diagnosis, to determine the predisposition to Keratoconus in this group.e

    Simultaneous examination of evolutionary history in island forms and closely related mainland relatives can provide reciprocal insight into the evolution of island and mainland faunas. The Cocos Flycatcher (Nesotriccus ridgwayi) is a small tyrant flycatcher (Tyrannidae) endemic to Cocos Island, an oceanic island in the eastern Pacific Ocean. We first established its close relationship to the mainland species Mouse-colored Tyrannulet (Phaeomyias murina) using a phylogeny from genome-wide ultraconserved elements and exons. We then used mitochondrial DNA to explore the relationships between Nesotriccus and Phaeomyias populations from across its distribution in Central and South America. We found that Nesotriccus is nested within the Phaeomyias evolutionary tree, and that Phaeomyias represents a complex of at least four evolutionarily distinct species that differ in plumage, voice, and habitat association. Nesotriccus underwent a population bottleneck subsequent to its divergence from Central American and northern South American Phaeomyias populations in the middle Pleistocene. The 46 UCE loci containing alleles that are fixed between the two species are widely distributed across the genome, which suggests that selective or neutral processes responsible for divergence have occurred genome-wide. Overall, our simultaneous examination of Phaeomyias and Nesotriccus revealed divergent levels of genetic diversity and evolutionary histories between island and mainland forms.

    Breast cancer is the most common cancer in women globally, and tumor size measured as the largest diameter of the tumor focus is currently used in tumor-lymph node-metastasis (TNM) staging for prognosis and treatment decisions. The present study utilized the tumor-to-breast volume ratio (TBR) to evaluate the relative tumor size and determined the prognostic impact of TBR on survival in patients with breast cancer. Two thousand twenty-five consecutive breast cancer patients who underwent modified radical mastectomy between January 2002 and December 2008 at Sun Yat-Sen University Cancer Center were enrolled in this retrospective study. Kaplan-Meier analysis was used to assess the prognostic effect of TBR on cancer-specific survival (CSS), and univariate log-rank test and multivariate Cox proportional hazards regression model were performed to identify independent prognostic factors. The optimal cutoff value of TBR was determined to be 1.70 %, and 1473 and 552 patients were categorized to low-TBR and high-TBR groups, respectively. In the whole patient cohort, CSS was significantly shorter in the high-TBR group (110.2 vs 128.5 months, P breast cancer patients (hazard ratio (HR) 1.489, 95 % CI 1.130-1.961, P = 0.005). High TBR was independently associated with poor prognosis in breast cancer patients. This variable may serve as a valuable parameter to predict the outcomes of breast cancer.

    Recent studies indicate that high-risk breast cancer patients (ie, women who carry mutations in BRCA1/2 genes) who opt for contralateral prophylactic mastectomy (CPM) have a substantially reduced risk of developing contralateral breast cancer. However, the immediate and long-term impact of this decision on women's quality of life and psychosocial functioning is largely unknown. In this study, we compared the impact of BRCA1/2 genetic test result and CPM on these outcomes among newly diagnosed breast cancer patients who opted for CPM at the time of their definitive surgical treatment versus patients who did not. Participants were 149 high-risk women who underwent genetic counseling and testing for alterations in the BRCA1/2 genes. We measured self-reported quality of life, cancer-specific distress, and genetic testing-specific distress using standardized instruments before receipt of genetic test results and again 1 and 12 months later. Compared with patients who chose breast conservation or unilateral mastectomy, those who chose mastectomy of the affected breast and CPM of the unaffected breast did not report diminished quality of life or elevated distress. With respect to quality of life and distress, patients who choose CPM fare as well as those who do not in the first year after surgery.

    Abstract Dexmedetomidine, a selective α2-agonist, reduces cerebral blood flow and has neuroprotective effects against cerebral ischemia/reperfusion injury in experimental animals. We examined whether intraoperative dexmedetomidine would reduce the incidence of postoperative cerebral hyperperfusion syndrome (CHS) after superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis in patients with moyamoya disease. The electronic medical records of 117 moyamoya patients who underwent STA-MCA anastomosis were reviewed retrospectively. The patients were divided into 2 groups: 48 patients received intraoperative dexmedetomidine (Group D), while 69 patients did not (Group ND). The incidence (primary outcome), onset, and duration of postoperative CHS were noted. The incidence of postoperative CHS was 45.8% and 40.6% in groups D and ND, respectively (P = 0.708). The duration of postoperative CHS was shorter in group D than in group ND (median [Q1–Q3], 5 [3–7] vs 8 [5–10] days, P = 0.021). There was no significant difference in the onset of CHS between group D and group ND (0 [0–2] vs 1 [0–3] days, P = 0.226). In conclusion, intraoperative dexmedetomidine did not reduce the incidence of postoperative CHS, although it reduced the duration of CHS, in patients who had undergone direct revascularization surgery for moyamoya disease.

    Introduction Rapid weight loss following bariatric surgery is associated with high incidence of gallstones and complications that may need bilioenteric diversion. This presents a specific challenge in the management of this group of patients. Case presentation A 37 years old female underwent a Roux-en-Y gastric bypass (RYGB) in 2008 for morbid obesity. In 2009 she presented with obstructive jaundice and was diagnosed with choledocholithiasis successfully managed by open cholecystectomy and choledochoduodenostomy. In the following years, she developed recurrent attacks of fever, chills, jaundice, and right upper quadrant pain and her weight loss was not satisfactory. Imaging of the liver showed multiple cholangitic abscesses. Reflux at the choledochoduodenostomy site was suggestive of sump syndrome as a cause of her recurrent cholangitis and a definitive surgical treatment was indicated. Intraoperative findings confirmed sump at the choledochoduodenostomy site and also revealed the presence of a large superficial accessory duct arising from segment four of the liver with separate drainage into the duodenum distal to the choledochoduodenostomy site. A formal hepaticojejunostomy was done after ductoplasty. The Roux limb was created by transecting the jejunum 40 cm distal to the foot anastomosis of the RYGB. The gastric limb was lengthened as part of this procedure which afforded the patient the additional benefit of weight loss. Conclusion Choledochoduodenostomy should be avoided in patients with RYGB due to the risk of sump syndrome which requires conversion to a formal hepaticojejunostomy. PMID:26921534

    Alzheimer's disease (AD) is associated with amyloid accumulation that takes place decades before symptoms appear. Cognitive impairment in AD is associated with reduced glucose metabolism. However, neuronal plasticity/compensatory mechanisms might come into play before the onset of dementia. The aim of this study was to determine whether there is evidence of cortical hypermetabolism as a compensatory mechanism before amyloid deposition takes place in subjects with amnestic mild cognitive impairment (aMCI). Nine AD subjects and ten aMCI subjects had both [{sup 11}C]PIB and [{sup 18}F]FDG PET scans with arterial input in order to quantify the amyloid deposition and glucose metabolism in vivo in comparison with healthy control subjects who underwent either [{sup 11}C]PIB or [{sup 18}F]FDG PET scans. The [{sup 11}C]PIB PET scans were quantified using [{sup 11}C]PIB target region to cerebellum uptake ratio images created by integrating the activity collected from 60 to 90 min, and regional cerebral glucose metabolism was quantified using spectral analysis. In MCI subjects, cortical hypermetabolism was observed in four amyloid-negative subjects and one amyloid-positive subject, while hypometabolism was seen in five other MCI subjects with high amyloid load. Subjects with hypermetabolism and low amyloid did not convert to AD during clinical follow-up for 18 months in contrast to four amyloid-positive hypometabolic subjects who did convert to AD. This preliminary study suggests that compensatory hypermetabolism can occur in aMCI subjects, particularly in those who are amyloid-negative. The increase in metabolic rate in different cortical regions with predominance in the occipital cortex may be a compensatory response to the neuronal damage occurring early in the disease process. It may also reflect recruitment of relatively minimally affected cortical regions to compensate for reduced function in the temporoparietal cortical association areas. (orig.)

  15. Long-term progress of six cases of malignant peripheral nerve sheath tumors of the mediastinum that underwent surgical treatment: Case report series

    Discussion and conclusions: Nerve sheath tumors localized within the membrane offer good long-term prognosis even if malignant. Furthermore, long-term survival is possible even if the tumor has invaded neighboring organs, provided it can be completely excised. In cases where complete excision is difficult, a multidisciplinary approach including radiotherapy and anti-cancer drug treatment may contribute to improved prognosis but this is a subject that requires further study.

    Alkaptonuria (AKU) is an autosomal recessive disorder caused by mutations in homogentisate-1,2-dioxygenase (HGD) gene leading to the deficiency of HGD enzyme activity. The DevelopAKUre project is underway to test nitisinone as a specific treatment to counteract this derangement of the phenylalanine-tyrosine catabolic pathway. We analysed DNA of 40 AKU patients enrolled for SONIA1, the first study in DevelopAKUre, and of 59 other AKU patients sent to our laboratory for molecular diagnostics. We identified 12 novel DNA variants: one was identified in patients from Brazil (c.557T>A), Slovakia (c.500C>T) and France (c.440T>C), three in patients from India (c.469+6T>C, c.650-85A>G, c.158G>A), and six in patients from Italy (c.742A>G, c.614G>A, c.1057A>C, c.752G>A, c.119A>C, c.926G>T). Thus, the total number of potential AKU-causing variants found in 380 patients reported in the HGD mutation database is now 129. Using mCSM and DUET, computational approaches based on the protein 3D structure, the novel missense variants are predicted to affect the activity of the enzyme by three mechanisms: decrease of stability of individual protomers, disruption of protomer-protomer interactions or modification of residues in the region of the active site. We also present an overview of AKU in Italy, where so far about 60 AKU cases are known and DNA analysis has been reported for 34 of them. In this rather small group, 26 different HGD variants affecting function were described, indicating rather high heterogeneity. Twelve of these variants seem to be specific for Italy.

    2016-07-12

    This study introduces dual-resolution Raman spectroscopy as a novel diagnostics approach for measurements of temperature and species in flames where multiple hydrocarbons are present. Simultaneous measurement of multiple hydrocarbons is challenging because their vibrational Raman spectra in the C–H stretch region are closely overlapped and are not well known over the range of temperature encountered in flames. Overlap between the hydrocarbon spectra is mitigated by adding a second spectrometer, with a higher dispersion grating, to collect the Raman spectra in the C–H stretch region. A dual-resolution Raman spectroscopy instrument has been developed and optimized for measurements of major species (N2, O2, H2O, CO2, CO, H2, DME) and major combustion intermediates (CH4, CH2O, C2H2, C2H4 and C2H6) in DME–air flames. The temperature dependences of the hydrocarbon Raman spectra over fixed spectral regions have been determined through a series of measurements in laminar Bunsen-burner flames, and have been used to extend a library of previously acquired Raman spectra up to flame temperature. The paper presents the first Raman measurements of up to twelve species in hydrocarbon flames, and the first quantitative Raman measurements of formaldehyde in flames. Lastly, the accuracy and precision of the instrument are determined from measurements in laminar flames and the applicability of the instrument to turbulent DME–air flames is discussed.

    The aim of this study was to investigate the effect of broken black tea with slightly hyper-normal fluoride content which was near the level of people tea-drinking habits on enamel morphological structure and its content of chemical elements. Thirty six rats were divided randomly into 3 groups: one was control group and another two groups fed with broken black tea infusion with F- content of 8.2 mg/l and 16.4 mg/l, respectively. After 360 days, collected 144 teeth, observed their morphological structure by electron micrograph, Scanning electron micrographs (SEM) and also analyzed concentrations of several chemical elements in tooth by x-ray fluorescence spectrometry (XRF). Chronic dental fluorosis in rats was induced by treatment with broken black tea with slightly hyper-normal fluoride content. Hyper-calcification and hypo-calcification appeared in enamel of those teeth from both broken black tea treated groups in dose-dependent manner. Twelve kinds of chemical elements, such as Ca, Mg, P, Al, Cl were examined. The contents of Ca, P, Mg were reduced and that of Al and Cl were increased significantly. Compared with control group, the levels of Si, S, Fe were lower in those teeth from treated group (broken black tea with the F- content of 8.2 mg/l), while higher in those teeth from treated group (broken black tea with the F- content of 16.4 mg/l). Long-term drinking broken black tea with hyper-normal fluoride content could cause chronic dental fluorosis, and its injury in enamel was related with Hyper-calcification and hypo-calcification mainly. Those changes of several chemical elements level in enamel, such as Ca, P, Al, Cl, were suggested that these chemical elements have influences on the development and mineralization of enamel.

    In 2001, an international surveillance initiative was established, utilising a validated larval development inhibition assay to track the susceptibility of cat flea isolates to imidacloprid. In 2009, an Australian node was incorporated into the programme, joining laboratories in the United States and Europe. Field isolates of Ctenocephalides felis eggs were submitted to participating laboratories and, where egg quantity and quality was sufficient, were placed in the imidacloprid discriminating dose bioassay for evaluation. Between 2002 and 2012, a total of 2,307 cat flea isolates were received across all sites; 1,685 submissions (73 %) were suitable for placement into the bioassay. In the Northern Hemisphere, isolate submission rate was influenced by season, with highest numbers submitted between June and October. In Australia, pets with flea infestations could be sourced year-round, and submission rate was largely influenced by programme factors and not climate. A total of 1,367 valid assays were performed between 2002 and 2012 (assay validity data was not recorded in 2001); adult flea emergence 5 % or greater at 3 ppm imidacloprid was observed in 38 of these assays (2.8 %). For these isolates that reached the threshold for further investigation, re-conduct of the assay using either a repeat challenge dose of 3 ppm of imidacloprid or a dose response probit analysis confirmed their susceptibility to imidacloprid. From 2009 to 2012, the Australian node performed valid assays on 97 field isolates from a total of 136 submissions, with no adult emergence observed at the 3-ppm imidacloprid discriminating dose. In addition to reviewing the data generated by this twelve-year initiative, this paper discusses lessons learned from the coordination and evolution of a complex project across geographically dispersed laboratories on three continents.

    There is no reproducibility study of fractional anisotropy (FA) measurements at 3T using regions of interest (ROIs). Our purpose was to establish the extent and statistical significance of the interrater variability, the variability observed with 2 different b-values, and in 2 separate scanning sessions. Twelve healthy volunteers underwent MR imaging twice. MR imaging was performed on a 3T unit, and FA maps were analyzed independently by 2 observers using ROIs positioned in the corpus callosum, internal capsules, corticospinal tracts, and right thalamus. Changes in FA values (x10(3)) measured with 2 b-values (700 and 1000 s/mm(2)), age-related differences, interobserver agreement, and measurement reproducibility were assessed. In the right internal capsule genu (FA = 702/728; b = 1000/700 s/mm(2)) and the left anterior limb of the internal capsule (AIC; FA = 617/745; b = 1000/700 s/mm(2)), the FA values were significantly different between the 2 b-values (P = .02 and .05, respectively). Significant age-related differences in FA were observed in the genu of the corpus callosum and in the left AIC. Interrater measurements showed fair-to-moderate agreement for most anatomic structures. The lowest significant change for a single subject regarding any FA values between the 2 sessions was in the corpus callosum (4%), whereas the highest one was in the corticospinal tracts (27%). The Bland-Altman plot analysis showed that the 1000-s/mm(2) b-value gave satisfactorily reproducible measurements equally good or better than the 700-s/mm(2) b-value. The reproducibility of FA estimates using ROIs was satisfactory. Measurements with a b-value at 1000 s/mm(2) showed superior reproducibility in most anatomic locations.

    Yarrowia lipolytica possesses twelve ALK genes, which encode cytochromes P450 in the CYP52 family. In this study, using a Y. lipolytica strain from which all twelve ALK genes had been deleted, strains individually expressing each of the ALK genes were constructed and their roles and substrate specificities were determined by observing their growth on n-alkanes and analyzing fatty acid metabolism. The results suggested that the twelve Alk proteins can be categorized into four groups based on their substrate specificity: Alk1p, Alk2p, Alk9p, and Alk10p, which have significant activities to hydroxylate n-alkanes; Alk4p, Alk5p, and Alk7p, which have significant activities to hydroxylate the ω-terminal end of dodecanoic acid; Alk3p and Alk6p, which have significant activities to hydroxylate both n-alkanes and dodecanoic acid; and Alk8p, Alk11p, and Alk12p, which showed faint or no activities to oxidize these substrates. The involvement of Alk proteins in the oxidation of fatty alcohols and fatty aldehydes was also analyzed by measuring viability of the mutant deleted for twelve ALK genes in medium containing dodecanol and by observing growth on dodecanal of a mutant strain, in which twelve ALK genes were deleted along with four fatty aldehyde dehydrogenase genes. It was suggested that ALK gene(s) is/are involved in the detoxification of dodecanol and the assimilation of dodecanal. These results imply that genes encoding CYP52-family P450s have undergone multiplication and diversification in Y. lipolytica for assimilation of various hydrophobic compounds.

    Full Text Available PURPOSE: To evaluate the performance of automated perimetry of elderly subjects naïve to AP after listening to a Mozart sonata. INTRODUCTION: Automated perimetry (AP is a psychophysical test used to assess visual fields in patients with neurological disorders and glaucoma. In a previous study, Fiorelli et al. showed that young subjects who listened to a Mozart sonata prior to undergoing AP performed better in terms of reliability than those who did not listen to the sonata. METHODS: Fifty-two AP-naïve, normal subjects underwent Automated perimetry (SITA 24-2. The study group (25 subjects underwent AP after listening to Mozart's Sonata for Two Pianos in D Major, and the control group (27 subjects underwent Automated perimetry without prior exposure to the music. RESULTS: The study group had significantly lower false negative rates and a lower visual field reliability score than the controls (P=0.04 and P=0.04, respectively. The test time was shorter for the study group (P=0.03. DISCUSSION: This study shows that elderly subjects, when exposed to the Mozart sonata immediately before AP testing, have lower false negative rates and lower visual field reliability scores when compared with an age- and gender-matched control group. Our results differ from those of Fiorelli et al. who found lower false positive rates and less fixation loss in addition to lower false negative rates. CONCLUSION: Listening to a Mozart sonata seems to improve automated perimetry reliability in elderly subjects.

    Full Text Available Background: Many patients show modulation of tinnitus by gaze, jaw or neck movements, reflecting abnormal sensorimotor integration and interaction between various inputs. Postural control is based on multi-sensory integration (visual, vestibular, somatosensory, and oculomotor and indeed there is now evidence that posture can also be influenced by sound. Perhaps tinnitus influences posture similarly to external sound. This study examines the quality of postural performance in quiet stance in patients with modulated tinnitus.Methods: Twenty-three patients with highly modulated tinnitus were selected in the ENT service. Twelve reported exclusively or predominately left tinnitus, eight right and three bilateral. Eighteen control subjects were also tested. Subjects were asked to fixate a target at 40cm for 51s; posturography was performed with the platform (Technoconcept, 40Hz for both the eyes open and eyes closed conditions.Results: For both conditions, tinnitus subjects showed abnormally high lateral body sway (SDx. This was corroborated by fast Fourrier Transformation (FFTx and wavelet analysis. For patients with left tinnitus only, medio-lateral sway increased significantly when looking away from the center. Conclusions: Similarly to external sound stimulation, tinnitus could influence lateral sway by activating attention shift, and perhaps vestibular responses. Poor integration of sensorimotor signals is another possibility. Such abnormalities would be accentuated in left tinnitus because of the importance of the right cerebral cortex in processing both auditory-tinnitus and attention.

    To describe the long-term results, quality of life and chronic pain after chest wall fixation for traumatic rib fracture using a quality of life (QOL) score and a numeric pain score. Retrospective analysis of 10 consecutive patients who underwent surgery for rib fractures after trauma and reconstruction between October 2010 and March 2012. Chest rib fractures were fixed with titanium clips and bars or titanium plates and screws through a posterolateral thoracotomy. Pain was assessed with a numeric pain scale 0-10 and quality of life (QOL) with the EORTC questionnaire QLQ-C30. There were 5 males and 5 females. The median age was 58 years (range 21-80). There were no postoperative deaths. The only postoperative complication observed was a contralateral pleural effusion requiring drainage. Median length of stay of the drain and median length of hospital stay were 2 days (range 0-8) and 4 days (range 1-42 days), respectively. The average follow-up period of operatively managed patients was 14 months (range 8-23.5 months). Seven patients scored the pain as 0, one as 1 (mild), one as 4 (moderate) and one as 8 (severe). Only two patients are taking occasionally pain killers. Only one patient presents severe limitation in his life scoring his QOL as poor. Titanium devices (clips and bars; screws and plates) are effective and safe for repair of rib fractures and showed good long-term results in terms of pain and quality of life after the operation.

    The rs9939609 single nucleotide polymorphism (SNP) in the fat mass and obesity-associated (FTO) gene is involved in obesity. Few studies have been conducted on patients who underwent bariatric surgery. The aim of this study was to evaluate the influence of FTO SNPs on body weight, body composition, and weight regain during a 60-mo follow-up period after bariatric surgery. The rs9939609 was genotyped in 146 individuals using a real-time polymerase chain reaction TaqMan assay. Data for lifestyle, comorbidities, body weight, body mass index (BMI), excess weight loss (EWL), and body composition were obtained before and 6, 12, 18, 24, 36, 48, and 60 mo after surgery. Data were analyzed by comparing two groups of patients according to rs9939609 FTO gene polymorphism. Mixed-regression models were constructed to evaluate the dynamics of body weight, BMI, and EWL over time in female patients. No differences were observed between the groups during the first 24 mo after surgery. After 36, 48, and 60 mo, body weight, fat mass, and BMI were higher, whereas fat-free mass and EWL were lower in the FTO-SNP patient group. Weight regain was more frequent and occurred sooner in the FTO-SNP group. There is a different evolution of weight loss in obese carriers of the FTO gene variant rs9939609 after bariatric surgery. However, this pattern was evident at only 2 y postbariatric surgery, inducing a lower proportion of surgery success and a greater and earlier weight regain. Copyright © 2015 Elsevier Inc.

    Traditional and non-traditional risk factors for atherosclerotic cardiovascular disease (ASCVD) are different between men and women. Gender-linked impact of epicardial adipose tissue volume (EATV) in patients undergoing coronary artery bypass grafting (CABG) remains unknown. Gender-linked impact of EATV, abdominal fat distribution and other traditional ASCVD risk factors were compared in 172 patients (men: 115; women: 57) who underwent CABG or non-coronary valvular surgery (non-CABG). In men, EATV, EATV index (EATV/body surface area) and the markers of adiposity such as body mass index, waist circumference and visceral fat area were higher in the CABG group than in the non-CABG group. Traditional ASCVD risk factors were also prevalent in the CABG group. In women, EATV and EATV index were higher in the CABG group, but other adiposity markers were comparable between CABG and non-CABG groups. Multivariate logistic regression analysis showed that in men, CABG was determined by EATV Index and other ASCVD risk factors including hypertension, dyslipidemia, adiponectin, high sensitive C-reactive protein (hsCRP) and type 2 diabetes mellitus (Corrected R2 = 0.262, p < 0.0001), while in women, type 2 diabetes mellitus is a single strong predictor for CABG, excluding EATV Index (Corrected R2 = 0.266, p = 0.005). Our study found that multiple risk factors, including epicardial adipose tissue volume and traditional ASCVD factors are determinants for CABG in men, but type 2 diabetes mellitus was the sole determinant in women. Gender-specific disparities in risk factors of CABG prompt us to evaluate new diagnostic and treatment strategies and to seek underlying mechanisms.

    Currently the surgical approach for papillary thyroid microcarcinoma (PTMC), particularly the range of lymph node dissection, remains controversial. The present study aims to evaluate the risk factors for central and lateral lymph node metastasis (CLNM and LLNM) for appropriate clinical decision of neck lymph node dissection in PTMC. A total of 66 cases of PTMC that underwent unilateral or bilateral lobectomy plus prophylactic cervical lymph node dissection were collected for clinicopathological evaluation, including age, gender, tumor size, subtypes, extrathyroidal invasion, multifocality, calcifications, loss of cellular polarity/cohesiveness (LOP/C) in the invasive front, CLNM and LLNM, and retrospectively analysis. Univariate analysis revealed that LOP/C was significantly associated with CLNM (P=0.001) and LLNM (P0.5 cm and multifocality were high-risk factors of LLNM (P=0.022, 0.044 and 0.005, respectively). Multivariable analysis revealed that LOP/C was significantly associated with CLNM [P=0.007, odds ratio (OR)=7.765, 95% confidence interval (CI)=1.773-33.996] and LLNM [P=0.029, OR=5.717, 95% CI=1.190-27.470]. Both multivariable analysis and χ(2) test revealed that CLNM was another important high-risk factor of LLNM (P=0.021, OR=5.444, 95% CI=1.290-22.969, χ(2)=17.867, PLOP/C and CLNM, which can be performed by intraoperative frozen section pathological examination. This must be considered discreetly in the case of patients with age 0.5 cm and multifocal lesions.

    Compared with dual antiplatelet therapy including aspirin and clopidogrel, triple antiplatelet therapy including cilostazol has a mortality benefit in patients with ST-segment elevation myocardial infarction. However, whether the mortality benefit persists in elderly patients is not clear. From 2007 to 2014, 1278 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were retrospectively analyzed. The patients were divided into four groups by age (antiplatelet strategy (triple or dual antiplatelet therapy). We compared the mortality rates between the triple and dual antiplatelet therapy groups. There were 1052 (male, 85%; mean age, 56.3 ± 10.4 years) patients in the young group and 241 (male, 52.7%; mean age, 80.3 ± 4.5 years) patients in the elderly group. In the young and elderly groups, 220 (20.9%) and 28 (12.3%) patients were treated with triple antiplatelet therapy. During a 1-year follow-up period, 80 patients died (4.2% in the young group vs. 15.5% in the elderly group). Kaplan-Meier survival analysis revealed that triple antiplatelet therapy was associated with a lower mortality rate in the young group (log-rank, p = 0.005). Although there were more angiographic high-risk patients in the elderly group, similar mortality rates were reported (log-rank, p = 0.803) without increased bleeding rates (1 vs. 3.6% in the elderly group, p = 0.217). Triple antiplatelet therapy might be a better antiplatelet regimen than dual antiplatelet therapy for patients with ST-segment elevation myocardial infarction. Although this benefit was strong in patients aged <75 years, no definite increase in major bleeding was seen for elderly patients (aged ≥75 years).

    Liver resection is an effective treatment in select patients with huge hepatocellular carcinoma (HCC, diameter ≥10 cm). This study aimed to develop nomograms for pre- and postoperative predictions of overall survival (OS) for these patients. There were 464 consecutive patients who underwent liver resection for huge HCC at the Eastern Hepatobiliary Surgery Hospital (EHBH) between January 2008 and December 2009. They were collected and divided into a training cohort (n = 310) and an internal validation cohort (n = 154). Another 90 patients who were operated on at the Fujian Medical University (FMU) between January 2008 and April 2010 served as an external validation cohort. The surgical morbidity, mortality, time to recurrence, and OS were observed. Two prognostic nomograms were developed based separately on the data obtained before and after surgery. Discrimination and predictive accuracy of the models were measured using concordance index (C-index), calibration curves, and validation study. The postoperative 4-year tumor recurrence and OS rates were, respectively, 79.0% and 41.2% in the patients from the EHBH and 78.8% and 37.6% in those from the FMU. Independent predictors of OS on multivariable analysis using pre- and postoperative data were respectively incorporated into the 2 nomograms. In the training cohort, calibration curves for the probability of 4-year postoperative survival fitted well. The C-indexes of the pre- and postoperative nomograms in predicting OS were 0.75 (95% CI 0.72 to 0.78) and 0.78 (95% CI 0.75 to 0.81), respectively. The internal and external validation studies optimally supported these results. The 2 nomograms achieved accurate pre- or postoperative predictions of long-term survival for patients with huge HCC after liver resection. Copyright © 2015 American College of Surgeons.

    Objectives This study evaluates midterm survival rates and risk factors for mortality of chronic dialysis-dependent patients undergoing cardiac surgery. Methods Fifty-three dialysis-dependent patients (34 males, aged 67 ± 12 years) with end-stage renal disease operated within March 2007 and May 2012 were analyzed retrospectively. Survival rates were calculated using Kaplan-Meier methods. Predictors of midterm survival were identified with multivariate Cox-regression analysis. Results Twenty-three patients received isolated coronary artery bypass graft surgery, 17 received isolated valve replacement, and 13 received combined procedures. Thirty-day mortality was 24.5% (n = 13). Follow-up was complete for 94.3% (n = 50). Survival rates at 1, 3, and 5 years were: 82, 50, and 17%, respectively. Neither age, gender, poor ejection fraction, emergency, ECC/X-clamp (cross-clamp) time, nor use of left internal thoracic artery or right internal thoracic artery had any influence on midterm survival. Causes of death within midterm follow-up period were related to cardiac events in 16% and neurological events in 16%. In the majority (47%), cause of death was associated with peripheral arterial disease (PAD).The only comorbidity, which could be identified as a significant risk factor, was PAD (p = 0.035). Five patients underwent successful renal transplantation within the follow-up period. Conclusion Although 30-day mortality in this high-risk patient population was increased, midterm survival rates were comparable to the results described in the literature. Cause of death within midterm follow-up period was mostly noncardiac related. Given the limited number of patients, predictors for enhanced 30-day mortality, such as preoperative myocardial infarction, prolonged extracorporeal circulation, operation time, and diabetes mellitus, did not have an influence on midterm survival.

    Background: Studies have not adequately compared subjective/objective ratings of female dermatology patients including patients presenting for cosmetic procedures. Objective: To examine objective versus subjective facial attractiveness ratings, demographic variables, and how men versus women judge female facial attractiveness. Methods: Sixty-five women (mean 42 years) presenting to a dermatology office. Subjects filled out a demographic and attractiveness questionnaire and were photographed. Four judges (2 male and 2 female) rated the photographs on a predefined 1 to 7 scale. Results: Mean subjective rating (subjects rating themselves) was 4.85 versus 3.61 for objective rating (judges rating subjects) (p<0.001). The mean age of subjects self-rating (subjective rating) who rated themselves in the 5 to 7 range was 39 years; the mean age of subjects self-rating (subjective rating) who rated themselves in the 3 to 4 range was 45 years (p=0.053). The mean age of subjects objectively rated by judges in the 5 to 7 range was 33 years; the mean age of subjects objectively rated by judges in the 3 to 4 range was 43 years (p<0.001); and the mean age of subjects objectively rated by judges in the 1 to 2 range was 50 years (p<0.001). The mean subjective rating (subjects rating themselves) for married women was 4.55 versus 5.27 for unmarried women (p=0.007); the mean objective rating (judges rating subjects) was 3.22 versus 4.15 (p<0.001). The mean objective rating by male judges was 3.09 versus 4.12 for female judges (p<0.001) Conclusion: Female patients presenting to a dermatology office rated themselves more attractive than did judges who viewed photographs of the subjects. Age and marital status were significant factors, and male judges rated attractiveness lower than female judges. Limitations of the study, implications, and suggestions for future research directions are discussed. PMID:21203353

  19. The Subject in Cognitive Psychotherapy

    Full Text Available This paper discusses the various subjects embedded in cognitive psychotherapy. The cognitive model developed by Beck, considered as a rationalist and modernist model, will exemplify these subjects. Cognitive therapy should be placed in the modernist historical context and related to a subject characterized as having rationality and the ability to observe and detect cognitions, emotions and behaviors. The paper develops this background introducing three main subject types. The first is the introspective and conscious subject, who is able to observe what is within oneself, has free access, and is conscious of one's cognitive world. The second is the cognitive miser that describes the subject who enters into therapy. The final subject identified, is the trained scientist who is able to develop a more objective knowledge, changing faulty schemas and cognitive distortions. This subject is the one most looked for in cognitive therapy. We could connect these subjects to some of the main elements of cognitive therapy such as the concept of ABC, assessment procedures, cognitive techniques or the relevance of schemas. Finally, the paper suggests some issues for study that could contribute to the theoretical and clinical evolution of cognitive psychotherapy.

    2013-12-01

    Empirical support for the recovery utility of 12-step mutual-help organizations (MHOs) has led to increased investigation of how such organizations confer benefit. The Twelve Promises of Alcoholics Anonymous (AA) feature prominently in 12-step philosophy and culture and are one of the few documented explications of the cognitive, affective, and behavioral benefits that members might accrue. This study investigated the psychometric properties of a measure of AA's Twelve Promises and examined whether it mediated the effect of 12-step participation on abstinence. Young adults (N=302, M age 20.4 [1.6], range 18-25; 27% female; 95% White) enrolled in an addiction treatment effectiveness study completed assessments at intake and 3-, 6-, and 12-months post treatment including a 26-item, Twelve Promises Scale (TPS). Factor analyses examined the TPS' psychometrics and lagged mediational analyses tested the TPS as a mechanism of behavior change. Robust principal axis factoring extraction with Varimax rotation revealed a 2-factor solution explaining 45-58% of the variance across three administrations ("Psychological Wellbeing"=26-39%; "Freedom from Craving=17-21%); internal consistency was high (alpha=.83-.93). Both factors were found to increase in relation to greater 12-step participation, but significant mediation was found only for the Freedom from Craving factor explaining 21-34% of the effect of 12-step participation in increasing abstinence. The TPS shows potential as a conceptually relevant, and psychometrically sound measure and may be useful in helping elucidate the extent to which the Twelve Promises emerge as an independent benefit of 12-step participation and/or explain SUD remission and recovery.

    We report here the characterization of twelve halobenzoquinones (HBQs) using electrospray ionization (ESI) high resolution quadrupole time-of-flight mass spectrometry. The high resolution negative ESI spectra of the twelve HBQs formed two parent ions, [M + H(+) + 2e(-)], and the radical M(-•). The intensities of these two parent ions are dependent on their chemical structures and on instrumental parameters such as the source temperature and flow rate. The characteristic ions of the HBQs were used to develop an ultra pressure liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method. At the UPLC flow rate (400 μL/min) and under the optimized ESI conditions, eleven HBQs showed the stable and abundant transitions [M + H(+) + 2e(-)] → X(-) (X(-) representing Cl(-), Br(-), or I(-)), while dibromo-dimethyl-benzoquinone (DBDMBQ) showed only the transition of M(-•) → Br(-). The UPLC efficiently separates all HBQs including some HBQ isomers, while the MS/MS offers exquisite limits of detection (LODs) at subng/mL levels for all HBQs except DBDMBQ. Combined with solid phase extraction (SPE), the method LOD is down to ng/L. The results from analysis of authentic samples demonstrated that the SPE-UPLC-MS/MS method is reliable, fast, and sensitive for the identification and quantification of the twelve HBQs in drinking water.

    A rat model of middle cerebral artery permanent occlusion was established using the modified Longa method. Successfully established model animals were treated by blood-letting puncture at twelve Jing-Well points of the hand, and/or by injecting mannitol into the caudal vein twice daily. Brain tissue was collected at 24, 48 and 72 hours after modeling, and blood was collected through the retinal vein before Evans blue was injected, approximately 1 hour prior to harvesting of brain tissue. Results showed that Evans blue leakage into brain tissue and serum nitric oxide synthase activity were significantly increased in model rats. Treatment with blood-letting punctures at twelve Jing-Well points of the hand and/or injection of mannitol into the caudal vein reduced the amount of Evans blue leakage into the brain tissue and serum nitric oxide synthase activity to varying degrees. There was no significant difference between single treatment and combined treatment. Experimental findings indicate that blood-letting punctures at twelve Jing-Well points of the hand can decrease blood-brain barrier permeability and serum nitric oxide synthase activity in rats following middle cerebral artery occlusion, and its effect is similar to that of mannitol injection alone and Jing-Well points plus mannitol injection.

    Objective: To observe the effect of blood-letting puncture at Twelve Well-Points of Hand on consciousness and heart rate in patients with early apoplexy. Method: Under observation were patients with disturbance of consciousness within 3 days after the apoplectic seizure. The patients were divided into a large injury team, a moderate injury team and a mild injury team. Each team was again randomly divided into a puncture group and a control group, with routine treatment in both groups but bloodletting puncture only in the puncture group. Quantitative changes in consciousness, blood pressure and heart rate of the patients were observed. Result: Blood-letting puncture at Twelve Well-Points of Hand can improve the consciousness and raise the systolic pressure in patients of the mild injury team, and accelerate the heart rate in all the patients in the puncture group. Conclusion: Blood-letting puncture at Twelve Well-Points of Hand can improve the consciousness of patients with brain injury in small area.

    Forty-three subjects worked in a private office with switchable electrochromic windows, manually-operated Venetian blinds, and dimmable fluorescent lights. The electrochromic window had a visible transmittance range of approximately 3-60%. Analysis of subject responses and physical data collected during the work sessions showed that the electrochromic windows reduced the incidence of glare compared to working under a fixed transmittance (60%) condition. Subjects used the Venetian blinds less often and preferred the variable transmittance condition, but used slightly more electric lighting with it than they did when window transmittance was fixed.

  15. Is Piaget's epistemic subject dead?

    Science.gov (United States)

    Lawson, Anton E.

    Niaz (1990) presents arguments in favor of the retention of Piaget's epistemic subject as a theoretical construct to guide research and practice in science education and psychology. The intent of this article is to point out the weaknesses of those arguments and to suggest that the weight of evidence argues against the existence of the logical thinker postulated by Piaget. Therefore, contrary to Niaz's conclusion that the acceptance of Piaget's epistemic subject will facilitate the development of cognitive theories with greater explanatory power, the conclusion is reached that Piaget's epistemic subject is dead and that continued acceptance of this aspect of Piagetian theory would be counterproductive.

    There is significant evidence that in the general population there are subjects either with fast or slow pulmonary mucociliary clearance rates. At the moment we do not know the physiological importance of such finding. Slow clearers should be regarded as a subpopulation at risk for bronchopulmonary diseases. Therefore, it would be of considerable interest if their mucociliary function could be stimulated by drugs for preventive purposes. Twelve apparently healthy subjects with slow mucociliary clearance rate, selected in an epidemiologic survey in a non-smokers population were given 0.6 g oral N-acetylcysteine/day/60 days in a double-blind cross-over randomized study. After treatment their mucociliary clearance rates increased by about 35% as compared with baseline values, and returned to pre-treatment values after the washout period. Subjects were unresponsive to placebo treatment. It would seem that slow clearers are protected against lung aggressions by prevention and/or mucus-active drugs.

    Full Text Available Backgrounds and Objective. During the procession of radiofrequency catheter ablation (RFCA in persistent atrial fibrillation (AF, transthoracic electrical cardioversion (ECV is required to terminate AF. The purpose of this study was to determine the impact of additional ECV on cardiac function and recurrence of AF. Methods and Results. Persistent AF patients received extensive encircling pulmonary vein isolation (PVI and additional line ablation. Patients were divided into two groups based on whether they need transthoracic electrical cardioversion to terminate AF: electrical cardioversion (ECV group and nonelectrical cardioversion (NECV group. Among 111 subjects, 35 patients were returned to sinus rhythm after ablation by ECV (ECV group and 76 patients had AF termination after the ablation processions (NECV group. During the 12-month follow-ups, the recurrence ratio of patients was comparable in ECV group (15/35 and NECV group (34/76 (44.14% versus 44.74%, P=0.853. Although left atrial diameters (LAD decreased significantly in both groups, there were no significant differences in LAD and left ventricular cardiac function between ECV group and NECV group. Conclusions. This study revealed that ECV has no significant impact on the maintenance of SR and the recovery of cardiac function. Therefore, ECV could be applied safely to recover SR during the procedure of catheter ablation of persistent atrial fibrillation.

    The aim of this paper was to report the continued mid-term follow-up of the first patients world-wide treated with the GORE(®) TIGRIS(®) Vascular Stent, a dual component stent consisting of a nitinol wire frame combined with a fluoropolymer-interconnecting structure. From December 2011 until November 2012, 32 consecutive patients (20 men, mean age 72.8 years) with 40 atherosclerotic femoropopliteal lesions (5% occlusions) underwent angioplasty and implantation of a GORE(®) TIGRIS(®) Vascular Stent. The patients were scheduled for follow-up at 3, 6 and 12 months after stent implantation for duplex ultrasound and assessment of Rutherford-Becker class (RBC) and Ankle-Brachial Index (ABI). Here we report the completed 6-month follow-up and, for the first time, a 12-month follow-up. The median follow-up was 418 days. During the 12-month follow-up 4 patients died. Restenosis or reocclusion of the stent in this time period was observed in 5 lesions (12.5%), resulting in a cumulative primary patency rate of 85.5±6.0%. The ABI increased pre-interventionally from 0.65±0.18 to 0.91±0.18 (PGORE(®) TIGRIS(®) Vascular Stent showed promising results with high 12-month primary patency rates after femoropopliteal endovascular interventions. These first clinical data are very promising compared to other stent concepts in the superficial femoral and popliteal artery.

    Summary Aim Aim of this study was to evaluate the prevalence of temporomandibular disorders (TMD) in a sample of consecutive subjects. Materials and methods TMDs were recorded in a sample of 580 subjects (279 M, 301 F; mean age: 13.4y). For each subject a case history was compiled to evaluate the social and demographic parameters. An extraoral exam was effected to point out the face proportions, and an intraoral exam was performed to analyze dental occlusion, mandibular deviation during opening, presence of cross-bites, overjet and overbite. A functional exam was carried out to evaluate mandibular movements and to find joint sounds and myofascial pain. The sample was divided into 6 groups according to the: gender, age (ages 6y–11y and 12y–16y), Angle Dental Class, cross-bite, midline deviation and chewing side. For this investigation latex gloves, a millimeter calipers (precision 0,01 mm) and a phonendoscope were used. The percentages of signs and symptoms were compared using the ?2-test with Yates correction to determine the differences among the groups for the rates of TMDs, reduced opening/lateral/protrusive movements, and myofascial pain. Results The prevalence of TMDs in the total sample was 13,9%. Among 6y–11y subjects the percentage of TMD was 7,3% while it was 16,1% among 12y–16y subjects (?2=1.634;; p=0.201). Females showed a percentage of 16,6% of TMDs while males one of 10,8% (?2=0.556;; p=0.456). According to angle malocclusion, the prevalence was 14% in subjects with Class I malocclusion, 15% in sample with Class II and 9% in patients with Class III (?2=0.540;; p=0.763). According to presence or absence of crossbite, prevalence of TMD signs and symptoms was 13,8% among subjects without crossbite and 14,3% among subjects with crossbite, with no significant difference between the two subgroups (?2= 0,047619;; p=0.050). In relation of midline deviation, prevalence of TMDs was 15% in subjects without deviation, 15,8% in functional deviation

    Full Text Available In recent work on null subject languages it has been claimed that preverbal subjects are always (clitic-left dislocated. In this paper, we argue against this claim, on the grounds of empirical evidence from European Portuguese concerning agreement facts, asymmetries between preverbal subjects and clitic-left dislocated XPs with respect to minimality effects, the existence of languages with a mixed system (null expletive subjects and full referential ones, language acquisition data, the behavior of negative QPs and interpretation facts, and propose a non-uniform analysis of preverbal subjects and clitic-left dislocated XPs that derives their topic interpretation from a predication rule stated configurationally (section 2. Our account of the SVO and VSO orders displayed in European Portuguese relies on a specific formulation of the EPP parameter, on the locality constraint Attract Closest X and on the independently motivated claim that V-movement targets T in European Portuguese (section 3. Under our analysis, the computational system generates equally economical SVO and VSO derivations and discourse considerations, at the appropriate interface, rule out the unfelicitous ones.

    To assess the hair surface condition, scanning electron microscope (SEM) is commonly used and it remains an indispensable hair morphology characterization technique. Yet, the technique is criticized for having subjective viewpoints and limitations in distinguishing the appearance of cuticle layers. The aim of this study is to establish an objective classification system and also to subdivide by detailed description of damaged cuticle layers. Hair samples were collected from female subjects (n = 500) who participated in hair efficacy study and Asian hair bunches (n = 180) that were previously collected. Damage to hair was initiated by chemical, heat stress and ultraviolet irradiation. We suggested the grading criterion on a 12-point scale and compared with a wide range grading system on a 5-point scale. We evaluated other hair surface-related parameters such as hair luster-ring and combing load to verify the validity and efficacy of our new grading system. The grading criterion on our 12-point scale revealed an improved discrimination compared to the wide range grading system. Hair surface-related parameters were significantly improved after hair care product, and these tendencies were likely to be determined to be similarly improved using the 12-point scale grading system. The 12-point scale classification system was demonstrated to be a more precise standardization and appropriate evaluation method to investigate the subtle distinction of the hair shaft after hair care product application. © 2016 John Wiley & Sons A/S.

    There is a high cardiac mortality in patients on long-term renal dialysis. No studies have reported long-term outcomes relating to both high-sensitivity cardiac troponin T (hs-cTnT) and high-sensitivity cardiac troponin I (hs-cTnI) in these patients. Patients who underwent long-term dialysis at the Canberra Hospital had blood samples collected for both cardiac and other biomarkers. Samples were stored at -80°C until analysis. Mortality data were collected at 5 years, and univariate and multivariate analyses were performed to identify which biomarkers were predictive of mortality at 5 years. After multivariate analysis, albumin, C-reactive protein (CRP), and hs-cTnT remained independently predictive of all-cause mortality, with hs-cTnT having the highest hazard ratio. If hs-cTnT was excluded from the analysis, then hs-cTnI was independently predictive of mortality. For hs-cTnT, for both genders, the ninety-ninth percentile, derived from a population with subjects with subclinical disease excluded, served as an excellent partition between survivors and nonsurvivors. Receiver-operating characteristic curve analysis for hs-cTnT had area under the curve of 0.798 and for hs-cTnI of 0.774. Kaplan-Meier curves for the aggregation of albumin, CRP, and hs-cTnT showed a stronger predictive power with receiver-operating characteristic area under the curve of 0.805. The addition of echocardiographic data in an analysis of all patients who had an echocardiogram for clinical reasons (n = 105) did not alter the final observations in this subgroup. In conclusion, hs-cTnT retains a superior predictive power in a dialysis-dependent population for identifying those at risk for death and when aggregated with albumin and CRP also has substantial additive value for identifying mortality risk in a renal-dialysis population.

    This study explored psychologic and physiologic factors differentiating patients with temporomandibular disorders (n = 23) from sex-, age-, and weight-matched asymptomatic control subjects. Each subject completed several standard psychologic questionnaires and then underwent two laboratory stressors (mental arithmetic and pressure-pain stimulation). Results indicated that patients with temporomandibular disorders had greater resting respiration rates and reported greater anxiety, sadness, and guilt relative to control subjects. In response to the math stressor, patients with temporomandibular disorders reacted with greater anger than did control subjects. There were no differences between patients with temporomandibular disorders and control subjects on pain measures or any other measured variable for the pressure-pain stimulation trial. In addition, there were no differences in electromyography levels between patients with temporomandibular disorders and control subjects. The results are discussed in terms of their implications for the etiology and treatment of this common and debilitating set of disorders.

    Reproducibility of subjective refraction measurement is limited by various factors. The main factors affecting reproducibility include the characteristics of the measurement method and of the subject and the examiner. This article presents the results of a study on this topic, focusing on the reproducibility of subjective refraction measurement in healthy eyes. The results of previous studies are not all presented in the same way by the respective authors and cannot be fully standardized without consulting the original scientific data. To the extent that they are comparable, the results of our study largely correspond largely with those of previous investigations: During repeated subjective refraction measurement, 95% of the deviation from the mean value was approximately ±0.2 D to ±0.65 D for the spherical equivalent and cylindrical power. The reproducibility of subjective refraction measurement in healthy eyes is limited, even under ideal conditions. Correct assessment of refraction results is only feasible after identifying individual variability. Several measurements are required. Refraction cannot be measured without a tolerance range.

    Full Text Available Purpose: To evaluate changes in choroidal thickness (CT in inherited retinal diseases and its relationship with age, spherical equivalent, visual acuity, and macular thickness. Methods: Retrospective analysis of 51 eyes with features of retinal dystrophy of 26 subjects, who underwent enhanced depth imaging using spectral domain (SD optical coherence tomography (OCT, were included. The CT measurements were made at the fovea and at 5 points with an interval of 500 microns in both directions, nasal and temporal from the fovea and were compared with age-matched healthy subjects. Step-wise regression was used to find the relationship between age, spherical equivalent, best-corrected visual acuity (BCVA, central macular thickness (CMT, and subfoveal CT. Results: Disease distribution was as follows: Stargardt′s disease 18 eyes (9 subjects; Best disease 5 eyes (3 subjects; cone-rod dystrophy 26 eyes (13 subjects; and Bietti′s crystalline dystrophy 2 eyes (1 subject. Mean subfoveal CT was 266.33 ± 76 microns. On regression analysis, no significant correlation was found between subfoveal CT and any other variable such as age (P = 0.9, gender (P = 0.5, CMT (P = 0.1, spherical equivalent (P = 0.3 and BCVA (P = 0.6. While comparing with age-matched healthy subjects, no significant statistical difference was noted (P < 0.05 among all age groups. Conclusion: Our study reports quantitative changes in CT in various common inherited retinal diseases seen in Indian populations. To validate changes in choroid, a longitudinal study with larger sample size is warranted.

  11. Twelve years' experience with direct-to-consumer advertising of prescription drugs in Canada: a cautionary tale.

    Directory of Open Access Journals (Sweden)

    Barbara Mintzes

    Full Text Available BACKGROUND: Direct-to-consumer advertising (DTCA of prescription drugs is illegal in Canada as a health protection measure, but is permitted in the United States. However, in 2000, Canadian policy was changed to allow 'reminder' advertising of prescription drugs. This is a form of advertising that states the brand name without health claims. 'Reminder' advertising is prohibited in the US for drugs that have 'black box' warnings of serious risks. This study examines spending on DTCA in Canada from 1995 to 2006, 12 years spanning this policy shift. We ask how annual per capita spending compares to that in the US, and whether drugs with Canadian or US regulatory safety warnings are advertised to the Canadian public in reminder advertising. METHODOLOGY/PRINCIPAL FINDINGS: Prescription drug advertising spending data were extracted from a data set on health sector spending in Canada obtained from a market research company, TNS Media Inc. Spending was adjusted for inflation and compared with US spending. Inflation-adjusted spending on branded DTCA in Canada grew from under CAD$2 million per year before 1999 to over $22 million in 2006. The major growth was in broadcast advertising, accounting for 83% of spending in 2006. US annual per capita spending was on average 24 times Canadian levels. Celebrex (celecoxib, which has a US black box and was subject to three safety advisories in Canada, was the most heavily advertised drug on Canadian television in 2005 and 2006. Of 8 brands with >$500,000 spending, which together accounted for 59% of branded DTCA in all media, 6 were subject to Canadian safety advisories, and 4 had US black box warnings. CONCLUSIONS/SIGNIFICANCE: Branded 'reminder' advertising has grown rapidly in Canada since 2000, mainly due to a growth in television advertising. Although DTCA spending per capita is much lower in Canada than in the US, there is no evidence of safer content or product choice; many heavily-advertised drugs in Canada

    Full Text Available El artículo sostiene la futilidad del Botox cuando éste se aplica en pacientes menores de doce años de edad con espasticidad, basándose principalmente en estudios realizados por diversos investigadores que plantean el actuar del fármaco sobre el cuerpo. Al tiempo que propone ampliar la visión en la atención de la discapacidad, partiendo de la persona como un ser integral, ubicándolo en su historia personal, en sus capacidades y etapa de la vida en que se encuentra, sin que se restrinja solo a la corporeidad del paciente. Plantea que los pacientes menores de doce años con espasticidad son personas que se encuentran en proceso de desarrollar sus capacidades y potencializarlas, la espasticidad se manifiesta por una triada: hipertonía, hiperrreflexia y reflejos patológicos, lo que limita la movilidad pero no la obstruye. Es resultado de la secuela de una lesión en las vías córtico espinales, por lo que el tratamiento debe de ir más allá de las expresiones corporales que el paciente hace evidente durante la realización de movimientos voluntarios.The following article presents the research of multiple investigators about the futility of Botox when this drug is applied on patients younger than twelve years old and the effects of the body of the subjects. At the same time invites to amply the vision on the attention of disability, taking the person as a complete being, placing his or hers personal history, his or hers capacities and the life phase he or she is living actually. Also shows that the patients with spasticity younger than twelve years old are people who is on process of developing his or hers capabilities and potencialize them, the spasticity is a sequel of injury on cortical spinal routes that manifest hypertonic, hiperreflex and pathologic reflexes that limit the mobility but do not impede it, so the treatment must be beyond corporal expressions that the patient made evident during the voluntary movement realization.

    The objective was to describe test-retest reliability and feasibility of the six minute walk test in adult subjects with myotonic dystrophy type 1. Twelve subjects (28-68 years, mean 44) performed three six minute walk tests on two occasions, one week apart. Relative reliability was high (ICC(2.1)=0.99) and absolute reliability values were low (standard error of measurement 12 m, repeatability 33 m). Feasibility was investigated in a sample of 64 subjects (19-70 years, mean 43). Fifty-two subjects were able to perform two tests on the same day. Subjects with severe proximal weakness had difficulties performing repeated tests. A practice trial followed by a second test on the same day can be recommended for most subjects, and the best test should be used for evaluations. In conclusion, even though the study sample was small, the present study indicates that the six minute walk test is reliable and feasible in subjects with myotonic dystrophy type 1.

  15. Psychoanalysis And Politics: Historicising Subjectivity

    Science.gov (United States)

    Layton, Lynne

    2013-01-01

    In this paper, I compare three different views of the relation between subjectivity and modernity: one proposed by Elisabeth Young-Bruehl, a second by theorists of institutionalised individualisation, and a third by writers in the Foucaultian tradition of studies of the history of governmentalities. The theorists were chosen because they represent very different understandings of the relation between contemporary history and subjectivity. My purpose is to ground psychoanalytic theory about what humans need in history and so to question what it means to talk ahistorically about what humans need in order to thrive psychologically. Only in so doing can one assess the relation between psychoanalysis and progressive politics. I conclude that while psychoanalysis is a discourse of its time, it can also function as a counter-discourse and can help us understand the effects on subjectivity of a more than thirty year history in the West of repudiating dependency needs and denying interdependence.

    The issue of the proper goals of science education and science teacher education have been a focus of the science education and philosophy of science communities in recent years. More particularly, the issue of whether belief/acceptance of evolution and/or understanding are the appropriate goals for evolution educators and the issue of the precise nature of the distinctions among the terms knowledge, understanding, belief, and acceptance have received increasing attention in the 12 years since we first published our views on these subjects. During that time, our own views about these issues have evolved, and this article presents a reconsideration of both these distinctions and the propriety of these goals. In particular, the present paper continues our discussion of the nature of belief as it relates to science education, and more specifically to evolution education. We extend that work to consider the import of the distinction between belief and acceptance.

  17. Visual perception of spatial subjects

    Principally, any imaging technology consists of two consecutive, though strictly separated processes: data acquisition and subsequent processing to generate an image that can be looked at, either on a monitor screen or printed on paper. Likewise, the physiological process of viewing can be separated into vision and perception, though these processes are much more overlapping. Understanding the appearance of a subject requires the entire sequence from receiving the information carried e.g. by photons up to an appropriate processing leading to the perception of the subject shown. As a consequence, the imagination of a subject is a result of both, technological and physiological processes. Whenever an evaluation of an image is critical, also the physiological part of the processing should be considered. However, an image has two dimensions in the first place and reality is spatial, it has three dimensions. This problem has been tackled on a philosophical level at least since Platon's famous discussion on the shadow image in a dark cave. The mere practical point is which structural details can be perceived and what may remain undetected depending on the mode of presentation. This problem cannot be resolved without considering each single step of visual perception. Physiologically, there are three 'tools' available to understanding the spatial structure of a subject: binocular viewing, following the course of perspective projection and motion to collect multiple aspects. Artificially, an object may be cut in various ways to display the interior or covering parts could be made transparent within a model. Samples will be shown how certain details of a subject can be emphasised or hidden depending on the way of presentation. It needs to be discussed what might help to perceive the true spatial structure of a subject with all relevant details and what could be misleading. (authors)

  18. Subject position affects EEG magnitudes.

    2013-01-01

    EEG (electroencephalography) has been used for decades in thousands of research studies and is today a routine clinical tool despite the small magnitude of measured scalp potentials. It is widely accepted that the currents originating in the brain are strongly influenced by the high resistivity of skull bone, but it is less well known that the thin layer of CSF (cerebrospinal fluid) has perhaps an even more important effect on EEG scalp magnitude by spatially blurring the signals. Here it is shown that brain shift and the resulting small changes in CSF layer thickness, induced by changing the subject's position, have a significant effect on EEG signal magnitudes in several standard visual paradigms. For spatially incoherent high-frequency activity the effect produced by switching from prone to supine can be dramatic, increasing occipital signal power by several times for some subjects (on average 80%). MRI measurements showed that the occipital CSF layer between the brain and skull decreases by approximately 30% in thickness when a subject moves from prone to supine position. A multiple dipole model demonstrated that this can indeed lead to occipital EEG signal power increases in the same direction and order of magnitude as those observed here. These results suggest that future EEG studies should control for subjects' posture, and that some studies may consider placing their subjects into the most favorable position for the experiment. These findings also imply that special consideration should be given to EEG measurements from subjects with brain atrophy due to normal aging or neurodegenerative diseases, since the resulting increase in CSF layer thickness could profoundly decrease scalp potential measurements.

    Analysis of psychological problems of the thalassemic subject shown with these following tests: Der Baumtest, drawing of the human figure. Moreover, we made meetings with all boys and their parents during their stay in the day-hospital. These tests have shown subjective conflicts (fear and uncertainty of future due to illness felt as aggression and fault, depressive moods and loneliness, problems of communication, hope in a magic recovery opposite to the constant discomfort of the therapeutic dependence) and relational conflicts (ambivalence towards parents, difficulties in becoming a part of the social and school environment).

Additionally, recent studies have shown beneficial effects of weight loss through diet and exercise in ghrelin concentrations in obese subjects. The aim of this study was to evaluate the effects of a 5% weight loss on lipid profile, resting metabolic rate (RMR, and acylated ghrelin (AG using two different methods of intervention (diet or diet plus exercise. Materials and methods: Eighteen subjects (twelve women and six men aged 20–40 years with a body mass index of 30–34.9 kg/m2 (grade 1 obesity were randomized into two intervention groups: diet (n=9 or diet plus exercise (n=9. Both groups underwent treatment until 5% of the initial body weight was lost. At baseline and upon completion, RMR and AG were analyzed. Results: Both groups showed a significant decrease in body fat percentage and fat mass. The diet-plus-exercise group showed a decrease in AG (pre: 54.4±25.3 pg/mL and post: 33.2±19.1 pg/mL and an increase in RMR (pre: 1,363±379 kcal/day, post: 1,633±223 kcal/day. Conclusion: These data suggest that diet plus exercise induced weight loss and had beneficial effects on AG concentration and RMR, essential factors to ensure the benefits of a weight-loss program.

    Poor sleep quality and orthostatic hypotension are common complaints in an older population, and both are related to factors such as polypharmacy and depression. However, it is not known whether there is a direct association between the two. Our objective is to investigate a potential association between orthostatic blood pressure response and subjective sleep quality in older people. A within-subjects, cross-sectional design embedded in a larger longitudinal study design. Participants were recruited from the community to visit the TRIL clinic at St James's Hospital, where they underwent a structured medical and psychosocial assessment. A total of 505 community dwelling adults aged 60+ (321 females, mean age 72.44) were participated in this study. Orthostatic blood pressure responses were recorded during an active stand using Finometer equipment, and health-related factors such as pain ratings, co-morbidities, polypharmacy, timed up and go, Mini-Mental State Examination score, body mass index, as well as depression, anxiety, age and gender, were also recorded. Self-reported sleep quality was also assessed using the Pittsburgh Sleep Quality Index. The results showed that timed up and go, polypharmacy, depression, anxiety, gender and delayed recovery of blood pressure at orthostasis were associated with subjective poor sleep quality. There is an association between subjective sleep quality and delayed recovery of blood pressure at orthostasis, independent of mental health or polypharmacy effects, in older adults. This link may have implications for the management of sleep disorders in older people.

    The quest for advancing scientific knowledge through human experimentations using vulnerable groups is traced back to ancient history, when Herophilus performed vivisections on prisoners. The violation of the rights of human subjects through the 20th century led to the formulation of the Nuremberg Code in 1947 and the Declaration of Helsinki in 1964. In the United States, the most infamous was the Tuskegee public health study that resulted in the enactment of the National Research Act that authorized the creation of the National Commission for the Protection of Human Subjects in Biomedical and Behavioral Research in 1974. In spite of existing federal regulations, the system of protecting human subjects is still flawed. Transparency of conflict ofinterest, clarity, and strict adherence to institutional guidelines are critical in safeguarding the rights and safety of human subjects and the integrity of research. Education on ethics and emerging complex ethical issues, global awareness, and governmental cooperation and sanctions are important steps in addressing the inadequacies in protecting the most vulnerable populations in experimentations worldwide. Investigators must always remember that the primary safeguards of protecting human life rest in their hands.

  11. Russia needs the Subjective Philosophy

    2012-01-01

    Full Text Available Based on the comparative analysis of different kinds of philosophic thinking, the paper reveals the advantages of subjective philosophy – the most adequate universal essentiality of socialized human being, opening the prospects for Russia as the creative society of cultural spontaneous activity. Objective principle of thinking is limited by the logic of outward definition. According to the above logic, people are regarded as tiny parts of social mechanism, the objects of manipulation. Separating action from spontaneous activity, object changes from self-alteration of human subject, executive functions from norm-creating ones brings about alienated practices and such social situation that makes individuals perceive their own existence as alien non- existence, or opposing existence.Subjectivity is a form of social activity regarding individuals and groups according to their ability in self-definition, self-organizing, self-control, norm-creating, as well as their actual rights and duties in social spheres of needs and objectives, and their feasible power over forces of nature and society. Subjective philosophy perceives the material production as the means for cultivating wholesome and spontaneously active individuals due to educational fundamentality and cultural prosperity. Accordingly, accumulation of capital turns into accumulation of culture and personal creativity growth. The results of the undertaken analysis and its conclusions can be implemented in developing creative anthropological bases for philosophy, pedagogy, psychology, economics, political science, as well as the relating discipline teaching.

    Full Text Available Considering the hypothesis that Bakhtin and his Circle‟s reflections can help us think about issues involving the field of Language Acquisition, in addition to the fact that there are only a few works developed within this perspective in Brazil, in this article, we intend to discuss the notions of “subject”, “subjectivity”,“individuality” and “singularity”, drawing on Bakhtin‟s theory. Thus, in order to make this discussion clearer, we bring data from the speech of young children, from 1.8 to 3 years old, who were filmed in natural contexts interacting with their parents and relatives. From these data, we could verify, among other things, that children, as individuals who constitute themselves as subjects in and throughlanguage, bring marks to their discourse, revealing their subjectivity (through lexical, morphological, syntactic or genre choices.

    Magnetoencephalography (MEG) was used to determine the neuroanatomical location of working memory (WM) processes. Differences between subjects with dyslexia (SD; n=5) and normal readers (NR; n=5) were studied during two WM tasks. A spatial WM task (SMW) consisted of blocks visually presented in one of 12 positions for 2 s each. Subjects were to determine if the current position matched the position presented 2 slides earlier (N-Back Test). The verbal task (VMW) consisted of presentation of a single letter. The location of cortical activity during SWM in NR (determined with MR-FOCUSS analysis) was in the right superior temporal gyrus (STG) and right angular gyrus (AG). Similar activation was seen in SD with a slight delay of approximately 20 ms. During VWM activity was seen in LEFT STG and LEFT AG in NR. In contrast for SD, activation was in the RIGHT STG and RIGHT AG. This study demonstrates the possibility to differentiate WM processing in subjects with and without learning disorders.

    The aim of the study was to analyse the effects of smoking, in particular to show its causal role in the development of airflow obstruction, and to look at changes in smoking habits. The study was conducted among 556 men, aged 30 to 54 in 1960, surveyed twice, in 1960 and 1972. The hypothesis of tobacco as a causal factor of airflow obstruction is strengthened, following this study, by three results: 1) FEV1 slope was related to tobacco consumption, even after adjustement for FEV1 level (42 ml/yrs for non-smokers, 51 ml/yrs for heavy smokers); 2) FEV1 loss with age increased with the amount of tobacco consumption: one pack a day smoked for 25 years was equivalent to an aging of 5 years; 3) FEV1 loss decelerated if the subject gave up smoking, thus preventing any further risk. What appeared to be a spontaneous regulation in smoking habits was observed. The men who stopped smoking were those with low respiratory status. In this population, men who were ex-smokers in 1960 and maintained this status until 1972 had a FEV1 slope similar to that of the non-smokers.

Aims: Our objective is to study the therapeutic options including psychotherapy, hormone, and surgical treatments used for alleviating GD in male–to–female (MTF transgender subjects in Eastern India. Subjects and Methods: This is a retrospective study of treatment preferences and outcome in 55 MTF transgender subjects who were presented to the endocrine clinic. Statistical Analysis Used: Descriptive statistical analysis is carried out in the present study, and Microsoft Word and Excel are used to generate graphs and tables. Results: The mean follow-up was 1.9 years and 14 subjects (25.5% were lost to follow-up after a single or 2–3 contact sessions. Rest 41 subjects (74.5% desiring treatment had regular counseling and medical monitoring. All 41 subjects were dressing to present herself as female and all of them were receiving cross-sex hormone therapy either estrogen only (68%, or drospirenone in combination with estrogen (12% or gonadotropin-releasing hormone agonist (GnRH in combination with estrogens (19.5%. Most of the subjects preferred estrogen therapy as it was most affordable and only a small number of subjects preferred drospirenone or GnRH agonist because of cost and availability. 23.6% subjects underwent esthetic breast augmentation surgery and 25.5% underwent orchiectomy and/or vaginoplasty. Three subjects presented with prior breast augmentation surgery and nine subjects presented with prior orchiectomy without vaginoplasty, depicting a high prevalence of poorly supervised surgeries. Conclusions: Standards of care documents provide clinical guidance for health professionals about the optimal management of transsexual people. The lack of information among health professionals about proper and protocolwise management leads to suboptimal physical, social, and sexual results.

    Functional MRI (fMRI) has become one of the most commonly used neuroimaging tools to assess the cortical effects associated with rehabilitation, learning, or disease recovery in subjects with stroke. Despite this, there has been no systematic study of the reliability of the fMR signal in this population. The purpose of this study was to examine the within- and between-session reliability of fMRI in cortical and cerebellar structures in subjects with stroke during a complex, continuous visual motor task performed with the less affected hand. Nine subjects with stroke underwent four testing trials during two sessions separated by three weeks. Subjects performed a drawing task using an MRI compatible joystick while in the MRI. Methods of analysis evaluated included: percent signal intensity change, active voxel count and a voxel by voxel stat value analysis within and between testing sessions. Reliability was determined with Interclass correlation coefficients (ICC) in the following regions of interest: primary motor (M1), primary sensory (S1), premotor cortex (PMC), medial cerebellum (MCB), and lateral cerebellum (LCB). Results indicate that intensity change has superior reliability to the other methods of analysis (Average ICC across brain regions and trials: intensity change: 0.73, voxel count: 0.58, voxel by voxel: 0.67) and that generally with any analysis method, within-session reliability was higher than between-session, as indicated by higher ICC values across brain regions. Overall, when comparing between-session results, moderate to good reliability was obtained with intensity change (ICC: M1: 0.52, S1: 0.80, SMA: 0.78, PMC: 0.94, MCB: 0.86, and LCB: 0.59). These results show good reliability in subjects with stroke when performing a continuous motor task. These findings give confidence for interpreting fMRI test/retest research in subjects with stroke.

    Subjects with Down syndrome (DS) have an increased susceptibility to infections and autoimmune disorders. ATP, adenosine, and acetylcholine contribute to the immune response regulation, and NTPDase, adenosine deaminase (ADA) and acetylcholinesterase (AChE) are important enzymes in the control of the extracellular levels of these molecules. We evaluated the activities of these enzymes and the cytokine levels in samples of DS individuals. The population consisted of 23 subjects with DS and 23 healthy subjects. Twelve milliliters of blood was obtained from each subject and used for lymphocyte and serum preparation. Lymphocytes were separated on Ficoll density gradients. After isolation, NTPDase and AChE activities were determined. The NTPDase activity using ADP as substrate was increased in lymphocytes of DS patients compared to control (P<0.05); however, no alterations were observed in the ATP hydrolysis. An increase was observed in the AChE activity in lymphocytes and in ADA activity in serum of DS patients when compared to healthy subjects (P<0.05). In DS subjects, an increase in the levels of IL-1β, IL-6, TNF-α and IFN-γ and a decrease in the IL-10 levels were also observed (P<0.05). Alterations in the NTPDase, ADA and AChE activities as well changes in the cytokine levels may contribute to immunological alterations observed in DS. Copyright © 2014 Elsevier B.V.

    Full Text Available We have investigated the relationship between fetal hemoglobin (HbF levels and metabolic control in subjects with insulin-dependent (N = 79 and non-insulin-dependent diabetes mellitus (N = 242. HbF and hemoglobin A1c (HbA1c levels were increased in subjects with type 1 and type 2 diabetes as compared to levels in nondiabetic individuals (P<0.0001, and were significantly higher in type 1 than in type 2 diabetes subjects. Lower levels of HbA1c and HbF were observed in type 2 diabetes subjects treated by diet, intermediate levels in those treated with oral hypoglycemic agents, and higher levels in those treated with insulin. HbF and HbA1c levels were correlated in type 1 diabetes (R2 = 0.57, P<0.0001 and type 2 diabetes (R2 = 0.58, P<0.0001 subjects. Following intense treatment, twelve diabetic patients showed significant improvement both in HbA1c and HbF values. We conclude that increased HbF levels reflect poor metabolic control in subjects with diabetes mellitus.

  3. Can subjective characteristics of benign headache predict manipulative physiotherapy treatment outcome?

    Science.gov (United States)

    Niere, Ken

    1998-01-01

    This study aimed to identify whether particular subjective reports of headache sufferers were predictive of outcome with manipulative physiotherapy treatment. One hundred and twelve subjects presenting for manipulative physiotherapy completed questionnaires relating to headache frequency, intensity, duration, pain quality, area, history and aggravating factors. Classification of treatment response was made using data collected two months after the initial visit. Diet as an aggravating factor, affective and autonomic pain descriptors, unilateral headaches and low frequencies each predicted a negative response to treatment. High frequencies predicted a positive response. If it is assumed that the treatment addressed cervical dysfunction then the cervical spine could have a varying component in a range of headache types rather than occupying a strict diagnostic category.

    In this article, we examine the recent shift in financial markets toward high-frequency trading (HFT). This turn is being legitimized with reference to how algorithms are allegedly more rational and efficient than human traders, and less prone to emotionally motivated decisions. We argue...... that although HFT does not render humans irrelevant, it is leading to a reconfiguration of both the ideal trading subject and the human–machine relations. Drawing on interviews with and ethnographic observations of high-frequency traders, as well as HFT ‘how to’ books, we analyze the subjectivity and self......-techniques of the ideal high-frequency trader. We demonstrate that these traders face the challenge of avoiding emotional interference in their algorithms and that they deploy a set of disciplinary self-techniques to curb the importance of emotional attachment....

    The aim of this work was to analyze muscle strength in Pilates novices who used the Reformer equipment during twelve training sessions. Twenty-four healthy young female volunteers, who were non-smokers and did not exercise regularly, were split into a control group (mean age 28 ± 4 years and BMI 24.55 ± 3.21 kg/m(2)) and a training group (mean age 29 ± 4 years and BMI 22.69 ± 2.87 kgm(2)). The data were checked for normality using the Kolmogorov-Smirnov test, and were then analyzed using the t-test (p Pilates group). The corresponding values for the lumbar muscles were 53.83 ± 11.66/53.28 ± 11.14 (control group) and 54.75 ± 10.27/64.80 ± 10.20 (Pilates group). After twelve sessions of Pilates with the Reformer equipment, there were improvements in lumbar extensor and scapular stabilizer strength. Several benefits are reported by practitioners of Pilates, but until now, there has been limited scientific evidence of the improvement of strength in the trunk and limbs after application of the technique.

    In a population of veterans with co-occurring substance use disorders and concomitant major depressive disorder, the current study compared mechanisms of change and therapeutic effects relevant to both disorders between integrated, dual disorder-specific cognitive behavioral therapy (ICBT) and twelve-step facilitation (TSF). Veterans (N = 148) were given standard pharmacotherapy for depression and were randomly assigned to receive 24 weeks of either TSF or ICBT. Process measures were selected to quantify (1) changes in self-efficacy in ICBT, (2) changes in ability to terminate negative affect in ICBT, (3) twelve-step affiliation (TSA) in TSF, and (4) changes in social support in both conditions. Measures of depression and substance use were administered to all participants before treatment, during treatment, and at the end of treatment. Self-efficacy increased among both TSF and ICBT participants during treatment, whereas self-reported ability to regulate negative affect did not change. Consistent with predictions, TSF participants increased community TSA during treatment, whereas those receiving ICBT reduced TSA. Changes in self-efficacy and TSA were associated with improvement in substance use outcomes at the end of treatment. Hypothesized changes in social support were not supported. Both ICBT and TSF produce improvements in self-efficacy, and these changes are related to substance use outcomes for depressed substance abusers. In TSF, intervention-specific changes in TSA occur during the course of treatment and are related to substance use outcomes.

    Full Text Available This study was undertaken to assess dietary crude protein (CP concentration for optimum growth performance and carcass characteristics of Lueyang black-boned chicken. In total, six hundred 42-day-old Lueyang black-boned chicks were randomly assigned to five treatments, each with six replicate pens with ten males and ten females. The birds fed experimental diets with different levels of protein concentration of 120, 140, 160, 180 and 200 g kg-1 from seven to twelve weeks of age respectively. On day of 84, weight gain, feed intake, and feed:gain ratio were measured, and two chickens (one male and one female close to the average weight of all birds in each treatment were selected from each pen and sacrificed to evaluate carcass traits and selected serum biochemical indexes. Dietary CP concentration did not have any significant influence on feed intake (p>0.05. The birds fed the diet with 180 or 160 g kg-1 CP concentration exhibited greater (p<0.05 growth rate, better feed conversion ratio, relative breast weight and albumin concentration in serum than that of those fed other dietary CP concentrations. According to the results of regression analysis, the CP requirements of Lueyang black-boned chicken from seven to twelve weeks of age for optimal weight gain and feed:gain ratio were 174 and 170 g kg-1, respectively.

However, there are no epidemiological data concerning this postural disorder. Defined by a posterior position of the centre of mass with respect to the base of support, backward disequilibrium is abnormal postural behavior, usually characterized by a posterior trunk tilt in standing and sitting positions, which predisposes subjects to backward falls. Many afflictions whether they are somatic (degenerative, ischemic and traumatic brain lesions, psychosomatic (psychomotor disadaptation syndrome, confinement to bed, nonuse situations or psychological (depression can cause backward disequilibrium. A vicious circle of falls, and loss of autonomy can arise and this is the main consequence of backward disequilibrium. Thus, in this paper, we review backward disequilibrium in elderly subjects with regard to the causes, consequences, assessment, and management.Keywords: backward disequilibrium, balance, elderly subject, falls, posture

    Tinnitus is the perception of sound with no external stimulus and idiopathic subjective tinnitus is the most common type in adults. Mean platelet volume (MPV) alterations were shown in some inflammatory diseases and were evaluated as a clinically useful marker. Our aim was to investigate MPV alterations in idiopathic subjective tinnitus patients. A total of 101 patients and 54 age- and sex-matched healthy control subjects were enrolled in the study. Patients included in the study had complaints of tinnitus for at least 3 months. All patients underwent detailed otolaryngologic examination, blood sampling, pure tone audiometry, magnetic resonance imaging of ear, and vertebrobasilar artery Doppler ultrasonography to make the differential diagnosis of tinnitus. Blood sampling consisted of renal-liver-thyroid function tests, lipid profile, and complete blood count. All tests and examinations except the imaging modalities were also performed for the control group. There were no differences in age and sex distribution of groups. Mean platelet volume values were significantly increased in tinnitus patients when compared with controls (p = 0.001). We think that MPV can be qualified as a useful marker in tinnitus patients.

    Impaired insulin action, frequently found in essential hypertension (HT), is modified by other factors, such as higher age, accumulation of body fat, dyslipidaemia, impaired glucose metabolism and endothelial dysfunction. In addition, antihypertensive and insulin-sensitizing medication itself may significantly affect cardiovascular and metabolic milieu. The aim of this study was to assess insulin sensitivity, acute insulin response, lipidaemic status and the adipokines' concentrations with regard to abdominal fat distribution in young, lean male subjects with treatment-naïve essential HT and in matched healthy normotensive (NT) subjects. We studied 27 HT patients (age: 19.9±0.6 years; body mass index (BMI): 22.9±0.5 kg m(-2)) and 15 NT controls (age: 22.3±1.0 years; BMI: 23.7±0.6 kg m(-2)). The subjects underwent an oral and an intravenous glucose tolerance test (OGTT, IVGTT) on separate days in random order. Higher fasting insulin (P<0.001), non-esterified fatty acids (P<0.05) and plasminogen activator inhibitor factor 1 concentrations (P<0.05) were found in HT patients when compared with NT patients. Despite comparable anthropometric parameters and body fat distribution assessed by magnetic resonance imaging in both groups, newly diagnosed untreated young hypertensive male subjects showed decreased insulin sensitivity, augmented insulin response to both oral and intravenous glucose load (P<0.01; P<0.05 respectively) and 'higher still normal' 2-h plasma glucose levels during OGTT. Untreated, young, lean hypertensive male subjects, with distribution of abdominal adipose tissue and lipid profile comparable with their healthy NT matched counterparts, showed considerable signs of insulin resistance and hyperinsulinaemia. We hypothesize that insulin resistance is the initial feature, which is influenced by several environmental factors, and HT is one of their common consequences.

  2. Risk assessment of K Basin twelve-inch and four-inch drain valve failure from a postulated seismic initiating event

    The Spent Nuclear Fuel (SNF) Project will transfer metallic SNF from the Hanford 105 K-East and 105 K-West Basins to safe interim storage in the Canister Storage Building in the 200 Area. The initial basis for design, fabrication, installation, and operation of the fuel removal systems was that the basin leak rate which could result from a postulated accident condition would not be excessive relative to reasonable recovery operations. However, an additional potential K Basin water leak path is through the K Basin drain valves. Three twelve-inch drain valves are located in the main basin bays along the north wall. Five four-inch drain valves are located in the north and south loadout pits (NLOP and SLOP), the weasel pit, the technical viewing pit, and the discharge chute pit. The sumps containing the valves are filled with concrete which covers the drain valve body. Visual observations indicate that only the valve's bonnet and stem are exposed above the basin concrete floor for the twelve-inch drain valve and that much less of the valve's bonnet and stem are exposed above the basin concrete floor for the five four-inch drain valves. It was recognized, however, that damage of the drain valve bonnet or stem during a seismic initiating event could provide a potential K Basin water leak path. The objectives of this analysis are to: (1) evaluate the likelihood of damaging the three twelve-inch drain valves located along the north wall of the main basin and the five four-inch drain valves located in the pits from a seismic initiating event, and (2) determine the likelihood of exceeding a specific consequence (initial leak rate) from a damaged valve. The analysis process is a risk-based uncertainty analysis where each variable is modeled using available information and engineering judgement. The uncertainty associated with each variable is represented by a probability distribution (probability density function). Uncertainty exists because of the inherent

    The relative lack of data on the dynamic posturography led us to start a study in order to give our contributions to the standardization of M1, M2, M3, response parameters in normal subjects. Our research was carried out on 35 normal subjects aged 21 to 50. All of them were standing in Romberg's position on a Tönnies model board in a normally lit and ventilated room. We performed two tests: the first one open-eyed staring at no point, the second, 5 minutes later, closed-eyed. The EMG signals were obtained by surface electrodes on triceps sural and front tibial muscles. The EMG recording was determined by a "tilt" movement of the board at a steady speed of 50 per sec. and 4 wide. We use a XT 286 IBM computer with "T POST" software for checking and testing the data. Our results showed a significant variation in the value of the duration parameter in open-eyed and closed-eyed tests. Latency and area values were inferior to those obtained by other authors, except for Diener and Dichgans (3) whose results differ in latency value only.

  4. Subjective measures of unconscious knowledge.

    Dienes, Zoltán

    2008-01-01

    The chapter gives an overview of the use of subjective measures of unconscious knowledge. Unconscious knowledge is knowledge we have, and could very well be using, but we are not aware of. Hence appropriate methods for indicating unconscious knowledge must show that the person (a) has knowledge but (b) does not know that she has it. One way of determining awareness of knowing is by taking confidence ratings after making judgments. If the judgments are above baseline but the person believes they are guessing (guessing criterion) or confidence does not relate to accuracy (zero-correlation criterion) there is evidence of unconscious knowledge. The way these methods can deal with the problem of bias is discussed, as is the use of different types of confidence scales. The guessing and zero-correlation criteria show whether or not the person is aware of knowing the content of the judgment, but not whether the person is aware of what any knowledge was that enabled the judgment. Thus, a distinction is made between judgment and structural knowledge, and it is shown how the conscious status of the latter can also be assessed. Finally, the use of control over the use of knowledge as a subjective measure of judgment knowledge is illustrated. Experiments using artificial grammar learning and a serial reaction time task explore these issues.

    2012-08-01

    From mid ´50s onwards, we witness a change of paradigm in the Western world: the expression of a historical shift from modernity to postmodernity. This new era includes a strong influence of the media on the population, a change from a lineal sense of time to a virtual, punctual one, and a flooding of overwhelming amount of information, mostly irrelevant, broadcasted in a de-contextualized, synchronic, fragmented and senseless fashion. This new age is characterized, above all, by the destitution of the State, the meta- institution source of legitimacy of all modern institutions: citizenship, factory, and mainly, School, an essential determinant this last one in the construction process of child subjectivity. Having lost its modeling power, the School loses its modern meaning, becoming thus a mere physical space in which pupils meet, but where general, transcendent rules, norms and values cannot be built, as in fact happened in modern times. According to Corea and Lewkowicz, school becomes an empty shed in which rules have to be built all the time, and become valid only for a particular occasion. These changes necessarily influence child subjectivity, the way they feel, they behave, and they "live" in contemporary society. Pediatricians have to be aware and try to understand these changes, so that we can help children, and, in doing so, to build a better world for them.

    Transdermal delivery is an advantageous method of drug administration, particularly for an elderly population. Microneedles (MNs) allow transdermal delivery of otherwise skin-impermeable drugs by creating transient micropores that bypass the barrier function of the skin. The response of aging skin to MNs has not been explored, and we report for the first time that micropore closure is delayed in elderly subjects in a manner that is dependent upon MN length, number, and occlusion of the micropores. Twelve control subjects (25.6±2.8years) and 16 elderly subjects (77.3±6.8years) completed the study. Subjects were treated with MNs of 500μm or 750μm length, in arrays containing 10 or 50 MNs. Impedance measurements made at baseline, post-MN insertion, and at predetermined time points demonstrated that restoration of the skin barrier is significantly slower in elderly subjects under both occluded and non-occluded conditions. This was confirmed via calculation of the total permeable area created by the micropores (which would approximate the area available for drug delivery), as well as calculation of the micropore half-life. This pilot study demonstrates that longer timeframes are required to restore the barrier function of aged skin following MN insertion, suggesting that drug delivery windows could be longer following one treatment with a MN array.

    Acipenseriformes is an endangered primitive fish group, which occupies a special place in the history of ideas concerning fish evolution, even in vertebrate evolution. However, the classification and evolution of the fishes have been debated. The mitochondrial DMA (mtDNA) ND4L and partial A7D4 genes were first sequenced in twelve species of the order Acipenseriformes, including endemic Chinese species. The following points were drawn from DNA sequences analysis: (i) the two species of Huso can be ascribed to Acipenser; (ii) A. dabryanus is the mostly closely related to A. sinensis, and most likely the landlocked form of A. sinensis; (iii) genus Acipenser in trans-Pacific region might have a common origin; (iv) mtDNA ND4L and ND4 genes are the ideal genetic markers for phylogenetic analysis of the order Acipenseriformes.

    Full Text Available Cassava brown streak disease is caused by two devastating viruses, Cassava brown streak virus (CBSV and Ugandan cassava brown streak virus (UCBSV which are frequently found infecting cassava, one of sub-Saharan Africa's most important staple food crops. Each year these viruses cause losses of up to $100 million USD and can leave entire families without their primary food source, for an entire year. Twelve new whole genomes, including seven of CBSV and five of UCBSV were uncovered in this research, doubling the genomic sequences available in the public domain for these viruses. These new sequences disprove the assumption that the viruses are limited by agro-ecological zones, show that current diagnostic primers are insufficient to provide confident diagnosis of these viruses and give rise to the possibility that there may be as many as four distinct species of virus. Utilizing NGS sequencing technologies and proper phylogenetic practices will rapidly increase the solution to sustainable cassava production.

    Subjective wellbeing and health are closely linked to age. Three aspects of subjective wellbeing can be distinguished-evaluative wellbeing (or life satisfaction), hedonic wellbeing (feelings of happiness, sadness, anger, stress, and pain), and eudemonic wellbeing (sense of purpose and meaning in life). We review recent advances in the specialty of psychological wellbeing, and present new analyses about the pattern of wellbeing across ages and the association between wellbeing and survival at older ages. The Gallup World Poll, a continuing survey in more than 160 countries, shows a U-shaped relation between evaluative wellbeing and age in high-income, English speaking countries, with the lowest levels of wellbeing in ages 45-54 years. But this pattern is not universal. For example, respondents from the former Soviet Union and eastern Europe show a large progressive reduction in wellbeing with age, respondents from Latin America also shows decreased wellbeing with age, whereas wellbeing in sub-Saharan Africa shows little change with age. The relation between physical health and subjective wellbeing is bidirectional. Older people with illnesses such as coronary heart disease, arthritis, and chronic lung disease show both increased levels of depressed mood and impaired hedonic and eudemonic wellbeing. Wellbeing might also have a protective role in health maintenance. In an analysis of the English Longitudinal Study of Ageing, we identify that eudemonic wellbeing is associated with increased survival; 29·3% of people in the lowest wellbeing quartile died during the average follow-up period of 8·5 years compared with 9·3% of those in the highest quartile. Associations were independent of age, sex, demographic factors, and baseline mental and physical health. We conclude that the wellbeing of elderly people is an important objective for both economic and health policy. Present psychological and economic theories do not adequately account for the variations in patterns

    Full Text Available CONTEXT: For the diagnosis of the diseases which affect the terminal ileum, the colonoscopy allows macroscopic evaluation and the performing of biopsies. Studies with criteria for the endoscopic and histological characterization of this segment are scarce and there are still some doubts about the need of biopsies in patients with normal ileoscopy. OBJECTIVE: Study the terminal ileum of patients who underwent colonoscopy considering: endoscopic and histological correlation; agreement between results of the initial histological evaluation and slides review, and the chance of subjects with normal ileoscopy with abdominal pain and/or chronic diarrhea to show histological alterations. METHODS: In a prospective study, 111 patients who presented smooth mucosa without enanthema in the endoscopic exam of the terminal ileum were selected. Biopsies of the ileal mucosa of such patients were performed, being the slides routinely examined and reviewed afterwards. RESULTS: The correlation between patients with normal ileoscopy and ileum with preserved histological architecture was of 99.1%. The agreement between initial histological evaluation and slides review calculated by the Kappa test was 0.21. In patients with abdominal pain and/or chronic diarrhea, the chance of showing histological alterations was 2.5 times higher than the others. CONCLUSIONS: The correlation between endoscopic and histological findings was high. The agreement between the initial histologic evaluation and slides review was not satisfactory. The chance of subjects with normal ileoscopy with abdominal pain and/or chronic diarrhea, showing histological alterations was higher in relation to the asymptomatic ones or with other symptoms, although the clinical importance of this datum was not evaluated.CONTEXTO: Para o diagnóstico de doenças que afetam o íleo terminal, a colonoscopia permite avaliação macroscópica e realização de biopsias.

    In France, the 2011–2012 influenza epidemic was characterized by the circulation of antigenically drifted influenza A(H3N2) viruses and by an increased disease severity and mortality among the elderly, with respect to the A(H1N1)pdm09 pandemic and post-pandemic outbreaks. Whether the epidemiology of influenza in France differed between the 2011–2012 epidemic and the previous outbreaks is unclear. Here, we analyse the age distribution of influenza like illness (ILI) cases attended in general practice during the 2011–2012 epidemic, and compare it with that of the twelve previous epidemic seasons. Influenza like illness data were obtained through a nationwide surveillance system based on sentinel general practitioners. Vaccine effectiveness was also estimated. The estimated number of ILI cases attended in general practice during the 2011–2012 was lower than that of the past twelve epidemics. The age distribution was characteristic of previous A(H3N2)-dominated outbreaks: school-age children were relatively spared compared to epidemics (co-)dominated by A(H1N1) and/or B viruses (including the 2009 pandemic and post-pandemic outbreaks), while the proportion of adults over 30 year-old was higher. The estimated vaccine effectiveness (54%, 95% CI (48, 60)) was in the lower range for A(H3N2) epidemics. In conclusion, the age distribution of ILI cases attended in general practice seems to be not different between the A(H3N2) pre-pandemic and post-pandemic epidemics. Future researches including a more important number of ILI epidemics and confirmed virological data of influenza and other respiratory pathogens are necessary to confirm these results. PMID:23755294

    cross-country studies on the institution-happiness association. Our findings suggest that their conclusions are qualitatively rather insensitive to the specific measure of 'happiness' used, while the associations between formal institutions and subjective well-being differ among poor and rich countries....... Separating different types of institutional quality, we find that in low-income countries the effects of economic-judicial institutions on happiness dominate those of political institutions, while analyses restricted to middle- and high-income countries show strong support for an additional beneficial effect......A long tradition in economics explores the association between the quality of formal institutions and economic performance. The literature on the relationship between such institutions and happiness is, however, rather limited, and inconclusive. In this paper, we revisit the findings from recent...

    The overwhelming events that lead to posttraumatic stress disorders and similar states are commonly understood to arise from noxious external events. It is however the unmasterable subjective experiences such events provoke that injure the mind and ultimately the brain. Further, traumatic over-arousal may arise from inner affective deluge with minimal external stimulation. Affects that promote suicide when sufficiently intense are reviewed; we propose that suicidal crises are often marked by repetitions (flashbacks) of these affects as they were originally endured in past traumatic experiences. Further, recurrent overwhelming suicidal states may retraumatize patients (patients who survive suicide attempts survive attempted murders, albeit at their own hands). We propose that repeated affective traumatization by unendurable crises corrodes the capacity for hope and erodes the ability to make and maintain loving attachments.

    Full Text Available Objective: To analyze postural control in acquired and congenitally blind adults. Methods: A total of 40 visually impaired adults participated in the research, divided into 2 groups, 20 with acquired blindness and 20 with congenital blindness - 21 males and 19 females, mean age 35.8 ± 10.8. The Brazilian version of Berg Balance Scale and the motor domain of functional independence measure were utilized. Results: On Berg Balance Scale the mean for acquired blindness was 54.0 ± 2.4 and 54.4 ± 2.5 for congenitally blind subjects; on functional independence measure the mean for acquired blind group was 87.1 ± 4.8 and 87.3 ± 2.3 for congenitally blind group. Conclusion: Based upon the scale used the results suggest the ability to control posture can be developed by compensatory mechanisms and it is not affected by visual loss in congenitally and acquired blindness.

    This paper describes of a set of subjective tests that the authors have carried out to assess the end user perception of video encoded with High Dynamic Range technology when viewed in a typical home environment. Viewers scored individual single clips of content, presented in High Definition (HD) and Ultra High Definition (UHD), in Standard Dynamic Range (SDR), and in High Dynamic Range (HDR) using both the Perceptual Quantizer (PQ) and Hybrid Log Gamma (HLG) transfer characteristics, and presented in SDR as the backwards compatible rendering of the HLG representation. The quality of SDR HD was improved by approximately equal amounts by either increasing the dynamic range or increasing the resolution to UHD. A further smaller increase in quality was observed in the Mean Opinion Scores of the viewers by increasing both the dynamic range and the resolution, but this was not quite statistically significant.

    The static subjective visual horizontal (SVH) test correlates with the dynamic ocular vestibular-evoked myogenic potential (oVEMP) test in healthy and pathological ears, and further confirms that both tests may, at least in part, share the same utricular reflex pathway. This study correlated the SVH test results with those of the oVEMP and cervical VEMP (cVEMP) tests to investigate their relationships. Twenty healthy subjects underwent the SVH test at a view pattern angle of 30° or 70° horizontal tilt under various background distractions to establish the optimal stimulation mode for SVH test. Thereafter, 20 patients with unilateral Meniere's disease underwent the SVH test using the optimal mode. In addition, oVEMP and cVEMP tests were performed in all subjects. The preliminary study in 20 healthy subjects at a view pattern angle of 70° under counterclockwise square background distraction revealed that the mean deviation degree of the SVH test was -0.61 ± 1.17°. Based on the criteria, abnormal percentages of SVH in 20 Meniere's patients were 40%. All healthy subjects had normal oVEMPs and cVEMPs. In contrast, eight patients (40%) showed abnormal oVEMPs and nine (45%) revealed abnormal cVEMPs. The SVH test results correlated significantly with oVEMP results, but not with cVEMP results.

    1985-08-01

    This study was undertaken to compare the myoelectric activity of the upper trapezius muscle before, during, and after intermittent, supine cervical traction. Twelve people with diagnosed disease or injury of the cervical spine served as subjects. Electromyographic recordings were taken from the upper trapezius muscle with bipolar surface electrodes. The subjects were treated with 20 minutes of intermittent, cervical traction at a force of 8% of their body weight. Recordings were taken with the subjects in the supine position before the traction, during one pull and release phase of the 10th and 20th minutes of traction, and after completion of the traction treatment. An analysis of variance with repeated measures showed no significant differences in the myoelectrical activity during the six time periods measured. The results of this study do not support the clinical use of intermittent, supine traction to produce cervical muscle relaxation.

  5. Different effects of growth hormone-releasing hormone (GRH) and somatostatin on growth hormone and stable metabolite of prostaglandin E2, 13, 14-dihydro-15-keto-prostaglandin E2 (PGE2-M) in normal subjects.

    Twenty four healthy subjects were placed in two treatment groups: 1. The first group consisted of twelve subjects in whom growth releasing hormone (GRH) (1 microgram/kg.BW) resulted in a marked and sustained elevation of serum growth hormone (GH) and a slight and delayed increase in plasma prostaglandin E2-M. In the second group, consisting also of twelve subjects, somatostatin infusion (500 micrograms/250 ml) was initiated and maintained for 60 min. Serum GH significantly decreased at 30 and 60 min during infusion and 15 min thereafter. We did not observe any changes in plasma prostaglandin E2-M during or after somatostatin infusion. The results obtained confirm previous in vitro studies and suggest a possible link between growth releasing hormone and prostaglandin E2 in their action on growth hormone secretion. It seems that somatostatin does not play a role in the control of prostaglandin E2 release.

  7. Conceptual change, subjectivity and Psychoanalysis

    Full Text Available We present the Conceptual Change Model (Posner et al., 1982 and detach how the presence of student’s subjectivity deeply marks the four conditions for the accomodation. The fundamental metaphor which supports the model, student as a little scientist, is limited, because does not consider the subjet’s relation with his community via language. We propose another metaphor: the learning process is similar with the psychoanalytic process. The analogy allow us to delineate in a sufficiently precise manner the functions and the importance of inicial diagnostic. Its goal are to problematize the unknown, to establish a pedagogical transfer and to categorize the basic structures of student’s thought by his relations with scientific principles. Finally, to mantain the envolvment of the student in the process, is fundamental the teacher’s attitude and ability to listen with attention, to create a school environment that allows the student to be free to speak, making his/her point of view explicit and to tackle challenges and conflicts.

  8. Authentic subjectivity and social transformation

    Directory of Open Access Journals (Sweden)

    Michael O'Sullivan

    2016-05-01

    Full Text Available Holiness in the Christian tradition has often been understood in a way that devalues embodiment and practical engagement with the world of one’s time. The latter understanding, for example, led to Marx’s critique and repudiation of Christianity. Both interpretations of holiness can be understood as mistaken efforts to express the dynamism for authenticity in contextualised human subjectivity. Vatican 2 opposed both views by addressing itself to all people of good will, declaring that everyone was called to holiness, and that authentic Christian identity involved solidarity with the world of one’s time, especially those who are poor. Vatican 2, therefore, provided an authoritative faith foundation for holiness expressed through social commitment and for viewing social commitment on the part of people of good will in whatever state of life as a form of holiness. This vision was also the conviction of leading spirituality writers of the period, like Thomas Merton, and inspired liberation theologians and the Latin American Catholic bishops at their conference in Medellín a few years after the Council. The argument of this article is that the emergence and development of a non-dualist Christian spirituality is grounded methodologically in the correct appropriation of the common innate dynamism for authenticity in concrete human persons and lived spiritual experiences consistent with and capable of enhancing this dynamism.

    This preliminary study determined if subjects with memory loss problems demonstrate changes in memory and cerebral blood flow (CBF) after a simple 8-week meditation program. Fourteen subjects with memory problems had an IV inserted and were injected with 250 MBq of Tc-99m ECD while listening to a neutral stimulus CD. They then underwent a pre-program baseline SPECT scan. Then subjects were guided through their first meditation session with a CD, during which they received an injection of 925 MBq ECD, and underwent a pre-program meditation scan. Subjects completed an 8-week meditation program and underwent the same scanning protocol resulting in a post-program baseline and meditation scan. A region of interest (ROI) template obtained counts in each ROI normalized to whole brain to provide a CBF ratio. Baseline and meditation scans and neuropsychological testing were compared before and after the program. The meditation program resulted in significant increases (pmemory showed improvements after training. This preliminary study evaluated whether an 8-week meditation program resulted in improvements in neuropsychological function and differences in CBF in subjects with memory loss. While the findings are encouraging, there are a number of limitations that can be addressed in future studies with more participants and more detailed analyses.

    The aim of this study was to determine the association of dental health behavior with health awareness, oral condition, and subjective symptoms in Japan. The present study included 1699 individuals who underwent dental checkups at the public health center of Miura City. All those who underwent dental checkups were asked to fill out a questionnaire. The correlation between having a regular dentist and each of the other items was analyzed. Undergoing regular checkups was significantly related to having a regular dentist. To analyze the correlation of dental health behavior with Subjective symptoms and Health awareness, structured equation modeling was performed following factor analysis. As a result, only the regression weight between dental health behavior and health awareness was found to be statistically significant. The present survey indicates that dental health behavior was significantly related to Health awareness but not to Subjective symptoms.

    Normotensive subjects with family history of hypertension (FHT) have been reported to have increased left ventricular mass index and reduced ventricular compliance. Of interest is whether blood pressure variability (BPV), which has been associated with target organ damage, is then part of this complex inherited syndrome? The objectives of this study are to determine whether there are any significant differences in BPV, arterial compliance and humoral factors in subjects with FHT as compared to controls. Thirty-five subjects with self reported FHT and 35 matched controls underwent 24 hour BP monitoring (BR-102, Schiller Inc. Germany). Arterial compliance was measured using systolic pulse wave tonometry (HDI/Pulsewave Cardiovascular Profiling Instrument, Hypertension Diagnostic Inc. USA). None of the subjects were hypertensive or diabetic. Out of these numbers, 25 subjects with FHT and 26 controls had measurements of plasma catecholamines, plasma renin and serum aldosterone. Catecholamines were assayed with high performance liquid chromatography, while both renin and aldosterone measurements were by radioimmunoassay. Subjects with FHT have higher night time BPV. There was no significant difference in arterial compliances between both groups. There were increased level of norepinephrine (NE) in subjects with FHT but epinephrine (E), renin and aldosterone levels were similar in both groups. There were no correlations between NE and BPV but E was negatively associated with daytime and mean arterial systolic BPV. In conclusion subjects with FHT demonstrated a higher night time BPV and NE level as compared to controls.

A prior study has suggested a dorsal horn modulated effect; however, the role of subject expectation was not considered. The purpose of the current study was to determine the effect of subject expectation on hypoalgesia associated with SMT. Methods Sixty healthy subjects agreed to participate and underwent quantitative sensory testing (QST to their leg and low back. Next, participants were randomly assigned to receive a positive, negative, or neutral expectation instructional set regarding the effects of a specific SMT technique on pain perception. Following the instructional set, all subjects received SMT and underwent repeat QST. Results No interaction (p = 0.38 between group assignment and pain response was present in the lower extremity following SMT; however, a main effect (p Conclusion The current study replicates prior findings of c- fiber mediated hypoalgesia in the lower extremity following SMT and this occurred regardless of expectation. A significant increase in pain perception occurred following SMT in the low back of participants receiving negative expectation suggesting a potential influence of expectation on SMT induced hypoalgesia in the body area to which the expectation is directed.

    The study investigated the extent to which approaches to work, workplace climate, stress, burnout and satisfaction with medicine as a career in doctors aged about thirty are predicted by measures of learning style and personality measured five to twelve years earlier when the doctors were applicants to medical school or were medical students. Prospective study of a large cohort of doctors. The participants were first studied when they applied to any of five UK medical schools in 1990. Postal questionnaires were sent to all doctors with a traceable address on the current or a previous Medical Register. The current questionnaire included measures of Approaches to Work, Workplace Climate, stress (General Health Questionnaire), burnout (Maslach Burnout Inventory), and satisfaction with medicine as a career and personality (Big Five). Previous questionnaires had included measures of learning style (Study Process Questionnaire) and personality. Doctors' approaches to work were predicted by study habits and learning styles, both at application to medical school and in the final year. How doctors perceive their workplace climate and workload is predicted both by approaches to work and by measures of stress, burnout and satisfaction with medicine. These characteristics are partially predicted by trait measures of personality taken five years earlier. Stress, burnout and satisfaction also correlate with trait measures of personality taken five years earlier. Differences in approach to work and perceived workplace climate seem mainly to reflect stable, long-term individual differences in doctors themselves, reflected in measures of personality and learning style.

    Full Text Available Beans are important dietary components with versatile health benefits. We analysed the extracts of twelve ecotypes of Phaseolus vulgaris in order to determine their phenolic profiles, antioxidant activity, and the in vitro antiproliferative activity. Ultra-performance liquid chromatography with diode array detector (UPLC-DAD admitted us to detect and quantify some known polyphenols, such as gallic acid, chlorogenic acid, epicatechin, myricetin, formononetin, caffeic acid, and kaempferol. The antioxidant activity (AA ranged from 1.568 ± 0.041 to 66.572 ± 3.197 mg necessary to inhibit the activity of the 2,2-diphenyl-1-picrylhydrazyl (DPPH radical by 50% (EC50. The extracts, except those obtained from the nonpigmented samples, were capable of inhibiting the proliferation of the human epithelial colorectal adenocarcinoma (Caco-2 cells, human breast cancer cells MCF-7, and A549 NSCLC cell line. Cultivars differed in composition and concentration of polyphenols including anthocyanins; cooking affected the antioxidant activity only marginally. Qualitative and quantitative differences in phenolic composition between the groups of beans influenced the biological activities; on the other hand, we did not find significant differences on the biological activities within the same variety, before and after cooking.

    Background Cocaine use remains a major problem within methadone maintenance programs. Disulfiram’s efficacy in reducing cocaine use has been demonstrated in several trials, but its relative efficacy among individuals who use versus abstain from alcohol remains unclear Treatment approaches which seek to enhance substance users’ involvement in self-help activities (Twelve Step Facilitation, TSF) have been associated with better outcomes among alcohol and cocaine users, but have rarely been evaluated among methadone-maintained cocaine-opioid users. Methods We conducted a randomized, placebo controlled, double blind (for medication condition), factorial (2×2) trial with 4 treatment conditions: Disulfiram plus TSF, disulfiram plus standard counseling only, placebo plus TSF, and placebo plus standard counseling in the context of a community-based methadone maintenance program. Participants (N=112) received either disulfiram (250 mg/d) or placebo in conjunction with daily methadone maintenance. Results Assignment to TSF was associated with less cocaine use throughout treatment and a higher number of cocaine-negative urines. While there were no significant main effects of disulfiram versus placebo, individuals without an alcohol use disorder demonstrated greater reductions in cocaine use over time when assigned to disulfiram. Conclusions TSF appears feasible in this methadone maintenance program and was associated with modest reductions in cocaine use, an often intractable problem in this setting. Support for the efficacy of disulfiram was weaker, as it appeared effective only for those without a current alcohol use disorder for this sample. PMID:22695473

    Current customers' demands focus on the nutritional and sensory quality of cattle meat. Candidate gene approach allows identification of genetic polymorphisms that have a measurable effect on traits of interest. The aim of this work is to identify new molecular markers for beef production through an association study using 27 candidate genes and 314 purebred bulls from 11 European cattle breeds. Twelve genes were found associated with different lipid and meat quality traits, and among these stand out the considerable effect of CAST on fatness score, CGGBP1 on growth traits, HSPB1 on the percentage of lauric acid (12:0) and phospholipid docosahexaenoic acid (DHA 22:6 n - 3), RORA on the ratio of light absorption (K) to light scattering (S) (K/S), and TNFA on lightness (L*). Most of these traits are related to post-mortem muscle biochemical changes, which are key factors controlling meat quality and consumers' acceptance. Also, the variations produced on muscle fatty acid profiles, such as those of AANAT, CRH, CSN3, HSPB1, and TNFA, give insights into the genetic networks controlling these complex traits and the possibility of future improvement of meat nutritional quality.

    In this work, a barley husk biomaterial was successfully carbonized by hydrothermal method. The carbon had a high specific surface area and good stability. It was coated onto a stainless steel wire through sol-gel technique to prepare a solid-phase microextraction fiber for the extraction of trace levels of twelve pesticides (tsumacide, fenobucarb, indoxacarb, diethofencarb, thimet, terbufos, malathion, thiamethoxam, imidacloprid, buprofezin, acetamiprid, thiamethoxam) from vegetable samples prior to gas chromatography-mass spectrometric (GC-MS) detection. The main experimental parameters that could influence the extraction efficiency such as extraction time, extraction temperature, sample pH, sample salinity, stirring rate, desorption temperature and desorption time, were investigated. Under the optimized conditions, the linearity was observed in the range of 0.2-75.0μgkg(-1) for tomato samples, and 0.3-60.0μgkg(-1) for cucumber samples, with the correlation coefficients (r) ranging from 0.9959 to 0.9983. The limits of detection of the method were 0.01-0.05μgkg(-1) for tomato samples, and 0.03-0.10μgkg(-1) for cucumber samples. The recoveries of the analytes for the method from spiked samples were in the range of 76%-104%, and the precision, expressed as the relative standard deviations, was less than 12%.

    It has been proposed to split the genus Burkholderia into two genera according to phylogenetic clustering: (1) a genus retaining this name and consisting mainly of animal and plant pathogens and (2) the genus Paraburkholderia including so-called environmental bacteria. The latter genus name has been validly published recently. During the period between the effective and valid publications of the genus name Paraburkholderia, 16 novel species of the genus Burkholderiawere described, but only two of them can be classified as members of this genus based on the emended genus description. Analysis of traits and phylogenetic positions of the other 11 species shows that they belong to the genus Paraburkholderia, and we propose to transfer them to this genus. The reclassified species names are proposed as Paraburkholderia dipogonis comb. nov., Paraburkholderia ginsengiterrae comb. nov., Paraburkholderia humisilvae comb. nov., Paraburkholderia insulsa comb. nov., Paraburkholderia kirstenboschensis comb. nov., Paraburkholderia metalliresistens comb. nov., Paraburkholderia monticola comb. nov., Paraburkholderia panaciterrae comb. nov., Paraburkholderia rhizosphaerae comb. nov., Paraburkholderia solisilvae comb. nov. and Paraburkholderia susongensis comb. nov. The remaining three species are transferred to the new genus Caballeronia gen. nov. proposed to accommodate twelve species of the genera Burkholderia and Paraburkholderia forming a distinctive clade in phylogenetic trees. The new genus members are Caballeronia choica comb. nov., Caballeronia cordobensis comb. nov., Caballeronia glathei comb. nov., Caballeronia grimmiae comb. nov., Caballeronia humi comb. nov., Caballeronia megalochromosomata comb. nov., Caballeronia jiangsuensis comb. nov., Caballeronia sordidicola comb. nov., Caballeronia telluris comb. nov., Caballeronia terrestris comb. nov., Caballeronia udeis comb. nov., and Caballeronia zhejiangensis comb. nov.
