    Full Text Available The paper is focused on the evaluation the rates of employment and unemployment of women, men and as a whole in ten associated countries of EU. Rates of employment were evaluated in the period 1996-2002. Rates of unemployment were evaluated in the period 1996-2003. Employment of males in all ten associated countries of EU is higher then employment of females. Unemployment of females in the Czech Republic, Cyprus, Malta, Poland, Slovakia and Slovenia is higher than unemployment of males and in opposite unemployment of females in Estonia, Hungary, Lithuania and Latvia is lower than unemployment of males. Trends of rates of male, female and total employment and unemployment are evaluated. Methods of regression and correlation analysis, development trends and cluster analysis were applied for the mathematical-statistical analysis.

    This paper shows that ten methods of company valuation using discounted cash flows (WACC; equity cash flow; capital cash flow; adjusted present value; residual income; EVA; business's risk-adjusted equity cash flow; business's risk-adjusted free cash flow; risk-free-adjusted equity cash flow; and risk-free-adjusted free cash flow) always give the same value when identical assumptions are used. This result is logical, since all the methods analyze the same reality using the same assumptions; t...

    Full Text Available Abstract Background The Australian Longitudinal Study on Male Health (Ten to Men was established in 2011 to build the evidence base on male health to inform policy and program development. Methods Ten to Men is a national longitudinal study with a stratified multi-stage cluster random sample design and oversampling in rural and regional areas. Household recruitment was conducted from October 2013 to July 2014. Males who were aged 10 to 55 years residing in private dwellings were eligible to participate. Data were collected via self-completion paper questionnaires (participants aged 15 to 55 and by computer-assisted personal interview (boys aged 10 to 14. Household and proxy health data for boys were collected from a parent via a self-completion paper-based questionnaire. Questions covered socio-demographics, health status, mental health and wellbeing, health behaviours, social determinants, and health knowledge and service use. Results A cohort of 15,988 males aged between 10 and 55 years was recruited representing a response fraction of 35 %. Conclusion Ten to Men is a unique resource for investigating male health and wellbeing. Wave 1 data are available for approved research projects.

    Full Text Available In Hymenoptera, homozygosity at the sex locus results in the production of diploid males. In social species, these pose a double burden by having low fitness and drawing resources normally spent for increasing the work force of a colony. Yet, diploid males are of academic interest as they can elucidate effects of ploidy (normal males are haploid, whereas the female castes, the queens and workers, are diploid on morphology and life history. Herein we investigated expression levels of ten caste-related genes in the stingless bee Melipona quadrifasciata, comparing newly emerged and 5-day-old diploid males with haploid males, queens and workers. In diploid males, transcript levels for dunce and paramyosin were increased during the first five days of adult life, while those for diacylglycerol kinase and the transcriptional co-repressor groucho diminished. Two general trends were apparent, (i gene expression patterns in diploid males were overall more similar to haploid ones and workers than to queens, and (ii in queens and workers, more genes were up-regulated after emergence until day five, whereas in diploid and especially so in haploid males more genes were down-regulated. This difference between the sexes may be related to longevity, which is much longer in females than in males.

    Three sublines of C57 Black/6M mice were propagated from three sibling pairs from the same litter. All breeders were weaned at 28+-2 days of age. At each generation in experimental lines weaned male breeders aged 35 days either received a single injection of tritiated thymidine (1 μCi/g of body weight) or were exposed for 5 weeks to tritiated drinking water (10 μCi/ml). At 10 weeks of age all breeders were sibling-mated. The time of delivery, the litter size and sex ratio was recorded. At each generation the offspring in the three lines were sibling-mated in the same sequence as their parents. At the 6th generation total offspring in the sibling line receiving tritiated thymidine numbered 108 versus 336 in the sibling line exposed to tritiated water, in contrast with 721 in the control sibling line. The 6th generation couples (20 in either subline) generated at the 9th generation 624 animals in the control subline versus 386 and 476 in the subline exposed to tritium. The data suggest a trend toward reduction in the subpopulation of offspring propagated from male parents exposed to tritiated water or tritiated thymidine. At the 9th generation 50 couples were assigned to a special study on reproductive fitness. The litter size was decreased and infant mortality was increased in experimental sublines (chi-square test, P<0.05). In control, as well as in experimental lines, at 70 days of age males were sibling-mated with their sisters. All animals received tap water and were not exposed at any time to tritiated thymidine or tritiated water. Preimplantation loss values were significantly increased in experimental versus control sublines (chi-square test, P<0.01). The dose to male sperm over a 35-day period was estimated at 3.7 rads from tritiated water and at 3.9 rads from tritiated thymidine under our experimental conditions

    The President's Emergency Plan for AIDS Relief (PEPFAR) has provided billions of US tax dollars to expand HIV treatment, care, and prevention programs in sub-Saharan Africa. This investment has generated significant health gains, but much less is known about PEPFAR's population-level economic effects. We used a difference-in-differences approach to compare employment trends between ten countries that received a large amount of PEPFAR funding (focus countries) and eleven countries that received little or no funding (control countries). We found that PEPFAR was associated with a 13 percent differential increase in employment among males in focus countries, compared to control countries. However, we observed no change in employment among females. In addition, we found that increasing PEPFAR per capita funding by $100 was associated with a 9.1-percentage-point increase in employment among males. This rise in employment generates economic benefits equal to half of PEPFAR's cost. These findings suggest that PEPFAR's economic impact should be taken into account when making aid allocation decisions. Project HOPE—The People-to-People Health Foundation, Inc.

  9. Point and interval forecasts of mortality rates and life expectancy: A comparison of ten principal component methods

    Full Text Available Using the age- and sex-specific data of 14 developed countries, we compare the point and interval forecast accuracy and bias of ten principal component methods for forecasting mortality rates and life expectancy. The ten methods are variants and extensions of the Lee-Carter method. Based on one-step forecast errors, the weighted Hyndman-Ullah method provides the most accurate point forecasts of mortality rates and the Lee-Miller method is the least biased. For the accuracy and bias of life expectancy, the weighted Hyndman-Ullah method performs the best for female mortality and the Lee-Miller method for male mortality. While all methods underestimate variability in mortality rates, the more complex Hyndman-Ullah methods are more accurate than the simpler methods. The weighted Hyndman-Ullah method provides the most accurate interval forecasts for mortality rates, while the robust Hyndman-Ullah method provides the best interval forecast accuracy for life expectancy.

  12. Epidemiologic methods for investigating male fecundity

    2014-02-01

    Full Text Available Fertility is a couple concept that has been measured since the beginning of demography, and male fecundity (his biological capacity to reproduce is a component of the fertility rate. Unfortunately, we have no way of measuring the male component directly, although several indirect markers can be used. Population registers can be used to monitor the proportion of childless couples, couples who receive donor semen, trends in dizygotic twinning, and infertility diagnoses. Studies using time-to-pregnancy (TTP may identify couple subfecundity, and TTP data will correlate with sperm quality and quantity as well as sexual activity and a number of other conditions. Having exposure data available for couples with a fecund female partner would make TTP studies of interest in identifying exposures that may affect male fecundity. Biological indicators such as sperm quality and quantity isolate the male component of fertility, and semen data therefore remain an important source of information for research. Unfortunately, often over half of those invited to provide a sperm sample will refuse, and the study is then subject to a selection that may introduce bias. Because the most important time windows for exposures that impair semen production could be early fetal life, puberty, and the time of ejaculation; longitudinal data over decades of time are required. The ongoing monitoring of semen quality and quantity should continue, and surveys monitoring fertility and waiting TTP should also be designed.

    2011-01-01

    Full Text Available This study investigated the effect of different traditional cooking methods on glycemic index (GI and glycemic response of ten Sweet potato (Ipomoea batatas cultivars commonly eaten in Jamaica. Matured tubers were cooked by roasting, baking, frying, or boiling then immediately consumed by the ten nondiabetic test subjects (5 males and 5 females; mean age of 27 ± 2 years. The GI varied between 41 ± 5–93 ± 5 for the tubers studied. Samples prepared by boiling had the lowest GI (41 ± 5–50 ± 3, while those processed by baking (82 ± 3–94 ± 3 and roasting (79 ± 4–93 ± 2 had the highest GI values. The study indicates that the glycemic index of Jamaican sweet potatoes varies significantly with the method of preparation and to a lesser extent on intravarietal differences. Consumption of boiled sweet potatoes could minimize postprandial blood glucose spikes and therefore, may prove to be more efficacious in the management of type 2 diabetes mellitus.

    Male urinary incontinence is relatively common complication of radical prostatectomy and of posterior urethroplasty following traumatic pelvic fracture. Here, we investigate the use of pedicled rectus abdominis muscle and fascia flap sling of the bulbar urethra for treatment for male-acquired urinary incontinence. Ten patients with acquired urinary incontinence were included in the study. Urinary incontinence was secondary to TURP in three patients and was secondary to posterior urethroplasty performed following traumatic pelvic fracture in seven patients. Pedicled rectus abdominalis muscle and fascial flaps, approximately 2.5 cm wide and 15 cm long, were isolated. The flaps were inserted into a perineal incision through a subcutaneous tunnel. The free end of the flap was sectioned to form two muscle strips, each 3 cm in length, and inserted into the space between bulbar urethra and corpus cavernosa. After adequate sling tension had been achieved, the two strips of muscle were anastomosed around the bulbar urethra using a 2-zero polyglactin suture. The patients were followed up for between 12 and 82 months (mean 42.8 months). Complete continence was achieved with good voiding in seven of the 10 patients. In other three patients achieved good voiding following catheter removal, but incontinence was only moderately improved. A pedicled rectus muscle fascial sling of the bulbar urethra is an effective and safe treatment for male patients with mild to moderate acquired urinary incontinence, but it may not be suitable for severe incontinence or for patients with weak rectus abdominalis muscles.

    Psychosocial job stressors are known to be associated with poor mental health. This research seeks to assess the relationship between psychosocial working conditions and suicidal ideation using a large dataset of Australian males. Cross-sectional study. Data from wave 1 of the Australian Longitudinal Study on Male Health (Ten to Men) was used to assess the association between suicidal ideation in the past two weeks and psychosocial working conditions using logistic regression. The sample included 11,052 working males. The exposures included self-reported low job control, high job demands, job insecurity and low fairness of pay. We controlled for relevant confounders. In multivariable analysis, persons who were exposed to low job control (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.05-1.26, P = 0.003), job insecurity (OR 1.69, 95% CI 1.44-1.99, P job stressors are highly prevalent in the working population and workplace suicide prevention efforts should aim to address these as possible risk factors.

    The majority of research on contraception has focused on manipulating the female reproductive system. Recent studies have identified novel contraceptives for males, including hormonal- and nonhormonal-based therapeutics. Although these new contraceptives are still undergoing clinical trials, their development and potential future use in society necessitate serious consideration of their implications for reproductive health. Through my analysis of the research conducted on male contraception over time and the current therapeutics available, it is clear that male contraception has the potential to shift societal gender dynamics and provide males with greater control over their own reproduction. This article also identifies the implications of these novel contraceptives for marginalized populations, especially men of color and men of lower socioeconomic positions. To overcome barriers to contraception among these populations, public policy efforts are needed in order to motivate the development of programs that facilitate coverage of these new male contraceptives by health plans and to increase their availability to underserved communities. Health care providers will be responsible for educating patients about these novel male contraception options and the need to continue using existing methods (e.g., condoms) in order to prevent sexually transmitted infections. This article analyzes the research conducted on male contraception and identifies the implications of these novel therapeutics for marginalized groups of men in the United States to identify the interventions that will be necessary to help ensure that all men have access to these promising scientific innovations.

    Murder is the most notorious crime that violates religious, social and cultural norms. Examining the types and number of different killing methods that used are pivotal in a murder case. However, the psychological traits underlying specific and multiple killing methods are still understudied. The present study attempts to fill this gap in knowledge by identifying the underlying psychological traits of different killing methods among Malaysian murderers. The study adapted an observational cross-sectional methodology using a guided self-administered questionnaire for data collection. The sampling frame consisted of 71 Malaysian male murderers from 11 Malaysian prisons who were selected using purposive sampling method. The participants were also asked to provide the types and number of different killing methods used to kill their respective victims. An independent sample t-test was performed to establish the mean score difference of psychological traits between the murderers who used single and multiple types of killing methods. Kruskal-Wallis tests were carried out to ascertain the psychological trait differences between specific types of killing methods. The results suggest that specific psychological traits underlie the type and number of different killing methods used during murder. The majority (88.7%) of murderers used a single method of killing. Multiple methods of killing was evident in 'premeditated' murder compared to 'passion' murder, and revenge was a common motive. Examples of multiple methods are combinations of stabbing and strangulation or slashing and physical force. An exception was premeditated murder committed with shooting, when it was usually a single method, attributed to the high lethality of firearms. Shooting was also notable when the motive was financial gain or related to drug dealing. Murderers who used multiple killing methods were more aggressive and sadistic than those who used a single killing method. Those who used multiple methods or

    2017-07-01

    To review the outcomes of patients treated with the Ilizarov method for an isolated, closed, simple diaphyseal, Tibial fracture at our institution over the last decade. The Ilizarov frame database was used to identify 76 skeletally mature patients who sustained an isolated, closed, extra-articular, simple, diaphyseal Tibial fracture; the injury also known as a "nail-able Tibial fracture." The average age of the patient was 38 (17-70). All 76 patients progressed to union. The average time until union was 148 (55-398) days. The coronal and sagittal alignment was 3° (0-17°) and 4° (0-14°) respectively. No patient suffered from compartment syndrome. No patient developed septic arthritis. No patient had documented anterior knee pain or secondary knee specialist input post frame removal. On average, there were 9(4-29) follow up appointments and 10(5-26) radiographs post frame application. There is a 59% chance of a patient having a difficulty post frame application. The malunion rate was 5%. Persisting pinsite infection post frame removal occurred in 5 patients (6.5%). Drilling of the pinsite sequestrum resolved the infection in four of these patients, giving a deep infection rate of 1.3%. The Ilizarov method has a role to play in the treatment of simple closed Tibial shaft fractures in patients who need to kneel. Patient education is a priority however; the patient must be made aware of the difficulty rate associated with the Ilizarov method when compared to the complication profile of alternative treatments.

    Kardum-Skelin, Ika

    2011-09-01

    Clinical cytology is an interdisciplinary medical diagnostic profession that integrates clinical, laboratory and analytical fields along with final cytologist's expert opinion. Cytology involves nonaggressive, minimally invasive and simple for use procedures that are fully acceptable for the patient. Cytology offers rapid orientation, while in combination with additional technologies on cytologic smear analysis (cytochemistry, immunocytochemistry for cell marker analysis, computer image analysis) or sophisticated methods on cytologic samples (flow cytometry, molecular and cytogenetic analysis) it plays a major role in the diagnosis, subtyping and prognosis of malignant tumors. Ten rules for successful performance in cytology are as follows: 1) due knowledge of overall cytology (general cytologist); 2) inclusion in all stages of cytologic sample manipulation from sampling through reporting; 3) due knowledge of additional technologies to provide appropriate interpretation and/or rational advice in dubious cases; 4) to preserve dignity of the profession because every profession has its advantages, shortcomings and limitations; 5) to insist on quality control of the performance, individual cytologists and cytology team; 6) knowledge transfer to young professionals; 7) assisting fellow professionals in dubious cases irrespective of the time needed and fee because it implies helping the patient and the profession itself; 8) experience exchange with other related professionals to upgrade mutual understanding; 9) to prefer the interest of the profession over one's own interest; and 10) to love cytology.

    Determination of time of death belongs to the most difficult and also the most important issues for the medical examiners, especially those who deal with violent death. Besides the most frequently evaluated postmortal changes it is sometimes possible to perform the evaluation on the basis of less frequently observed findings. One of such findings is for example the fungal multiplication on the body or in the very close vicinity. Knowledge of moulds as well as information about their speed of growth should contribute to confirmation or negation of some information gained during police investigation. In this case report authors describe the macroscopically visible fungal intracardiac multiplication in heart chambers and aorta in an almost totally carbonised body which was missing for only ten days. Based on the molecular examination it was detected that the body belonged to the 64-year-old man who was repeatedly hospitalised in psychiatry for depression with suicidal tendencies. The last hospitalisation was six weeks before death and there was no organic disability. The cause of fire was a naked flame. The cause of death was burn injury or asphyxia. The almost total carbonisation did not allow to perform toxicological investigation. By histological investigation we found the presence of wide long non-septate moulds growing in the heart muscle, which belonged to the order Mucor. Since there was no obvious inflammatory response, we suppose their growth started on the congealed blood after death.

    2008-01-01

    This study aimed at examining the effect of tripolar TENS of vertebral column on the activity of slow and fast motoneurons on 10 healthy non-athlete women aged 22.7 +/- 2.21 yrs. H-reflex recovery curve of soleus (slow) and gastrocnemius (fast) muscles were recorded before and after applying tripolar TENS. For recording of this curve, rectangular paired stimuli were applied on tibial nerve (with 40-520 ISI, frequency of 0.2 Hz and pulse width of 600 micros). Our findings showed that maximum H-reflex recovery in gastrocnemius muscle appeared in the shorter ISI, while in soleus muscle, it appeared in the longer ISI and its amplitude slightly decreased after applying tripolar TENS. It is suggested that tripolar TENS excites not only the skin but also Ia and Ib afferents in the dorsal column. A Synaptic interaction of these afferents in spinal cord causes the inhibition of type I MNs and facilitation of type II MNs. This effect can be used in muscle tone modulation.

    Adolescent males interested in sex with males (AMSM) are an important audience for HIV prevention interventions, but they are difficult to reach due to their age and social stigma. We aim to identify efficient methods to recruit and retain AMSM in online research. Interviews with 14-to-18-year-old AMSM (N=16) were conducted at 2017 Pride events in Boston, MA and Providence, RI. Participants reported that (1) social media platforms are viable recruitment venues; (2) recruitment advertisements should describe the study using colorful/bright pictures, familiar words, and information about compensation; (3) surveys should be recruitment and retention procedures to increase the efficiency of HIV prevention research for this at-risk group. ©Kimberly M Nelson, Jaime J Ramirez, Michael P Carey.

    Full Text Available Abstract Background Release of genetically-modified (GM or sterile male mosquitoes for malaria control is hampered by inability to assess the age and mating history of free-living male Anopheles. Methods Age and mating-related changes in the reproductive system of male Anopheles gambiae were quantified and used to fit predictive statistical models. These models, based on numbers of spermatocysts, relative size of sperm reservoir and presence/absence of a clear area around the accessory gland, were evaluated using an independent sample of mosquitoes whose status was blinded during the experiment. Results The number of spermatocysts in male testes decreased with age, and the relative size of their sperm reservoir increased. The presence of a clear area around accessory glands was also linked to age and mating status. A quantitative model was able to categorize males from the blind trial into age groups of young (≤ 4 days and old (> 4 days with an overall efficiency of 89%. Using the parameters of this model, a simple table was compiled that can be used to predict male age. In contrast, mating history could not be reliably assessed as virgins could not be distinguished from mated males. Conclusion Simple assessment of a few morphological traits which are easily collected in the field allows accurate age-grading of male An. gambiae. This simple, yet robust, model enables evaluation of demographic patterns and mortality in wild and released males in populations targeted by GM or sterile male-based control programmes.

    To study the characteristics and changes in the total Oswestry Disability Index (ODI) and in its ten component items in female and male patients pre- and post-surgery for lumbar disc herniation. Ninety-eight patients [mean (SD) age 43 (13), 61% males] undergoing lumbar disc herniation surgery were selected for this clinical 12-month follow-up. Subjective disability and back and leg pain were assessed by ODI version 1.0 and the visual analog scale. Pre-operatively females had a significantly higher mean (SD) total ODI [59(3)] than males [51(2)] (P = 0.030). Females were more disabled in the walking, sex life, social life and travelling items of the ODI compared to males. The total Oswestry decreased by 38 (95% CI − 44 to − 31) in females and by 34 (− 39 to − 30) in males at the 1-year follow-up. Most of the improvement (88% in females and 80% in males) occurred during the first 6 weeks; thereafter the changes were minor. In males the changes were greatest in pain, social life and travelling and in females in walking, social life and travelling. Internal consistency value of ODI was 0.88 (95% CI 0.82–0.91). Item analysis of the ODI showed that all the items except pain had high corrected item correlation. As recovery following lumbar disc surgery occurred to a great extent during the first 6 weeks, the early post-operative outcome appears to be quite a reliable indicator of the overall post-operative outcome over the 1-year follow-up. The ODI proved to capture a wide range of disability in these lumbar disc surgery patients, thereby supporting the future use of the index. The “pain intensity” component, which collects data on the use of painkillers in version 1.0 of the ODI did not support the item structure of the index in this study. The use of ODI version 2.0 might remove this problem. PMID:16912888

    Haloacetic acids (HAAs) are by-products of the chlorination of drinking water containing natural organic matter and bromide. A simple and sensitive method has been developed for determination of ten HAAs in drinking water. The pressure-assisted electrokinetic injection (PAEKI), an on-line enrichment technique, was employed to introduce the sample into a capillary electrophoresis (CE)-electrospray ionization-tandem mass spectrometry system (ESI-MS/MS). HAAs were monitored in selected reaction monitoring mode. With 3 min of PAEKI time, the ten major HAAs (HAA10) in drinking water were enriched up to 20,000-fold into the capillary without compromising resolution. A simple solid phase clean-up method has been developed to eliminate the influence of ionic matrices from drinking water on PAEKI. Under conditions optimized for mass spectrometry, PAEKI and capillary electrophoresis, detection limits defined as three times ratio of signal to noise have been achieved in a range of 0.013-0.12 μg L(-1) for ten HAAs in water sample. The overall recoveries for all ten HAAs in drinking water samples were between 76 and 125%. Six HAAs including monochloro- (MCAA), dichloro- (DCAA), trichloro- (TCAA), monobromo- (MBAA), bromochloro- (BCAA), and bromodichloroacetic acids (BDCAA) were found in tap water samples collected.

    The Australian species of the Orthocladiinae genus Cricotopus Wulp (Diptera: Chironomidae) are revised for larval, pupal, adult male and female life stages. Eleven species, ten of which are new, are recognised and keyed, namely Cricotopus acornis Drayson & Cranston sp. nov., Cricotopus albitarsis Hergstrom sp. nov., Cricotopus annuliventris (Skuse), Cricotopus brevicornis Drayson & Cranston sp. nov., Cricotopus conicornis Drayson & Cranston sp. nov., Cricotopus hillmani Drayson & Cranston, sp. nov., Cricotopus howensis Cranston sp. nov., Cricotopus parbicinctus Hergstrom sp. nov., Cricotopus tasmania Drayson & Cranston sp. nov., Cricotopus varicornis Drayson & Cranston sp. nov. and Cricotopus wangi Cranston & Krosch sp. nov. Using data from this study, we consider the wider utility of morphological and molecular diagnostic tools in untangling species diversity in the Chironomidae. Morphological support for distinguishing Cricotopus from Paratrichocladius Santo-Abreu in larval and pupal stages appears lacking for Australian taxa and brief notes are provided concerning this matter.

    Tsetse flies are able to emit different acoustic signals. An acoustic method to test the quality of sterilized male tsetse flies was developed. Differences in the sound characteristics between males and females, between sterilized and unsterilized males, and between males sterilized in air and nitrogen, were determined. Also, the acoustic parameters (frequency, time, sound pressure level) of the sounds that are useful as criteria for quality control were determined. It was demonstrated that only the so-called 'feeding sounds' can be used as a quality criterion. Both sexes emitted feeding sounds while feeding on a host. These sounds were also used to find sexual partners, and had an effect on male copulation success. An acoustic sound analysis programme was developed; it automatically measured sound activity (only feeding sounds) under standard conditions (random sample, relative humidity, temperature, light intensity).

    Ten Salvia species, S. amplexicaulis, S. austriaca, S. forsskaolii S. glutinosa, S. nemorosa, S. officinalis, S. pratensis, S. sclarea, S. stepposa and S. verticillata were fractionated using supercritical carbon dioxide and pressurized liquid (ethanol and water) extractions. Fifteen phytochemicals were identified using commercial standards (some other compounds were identified tentatively), 11 of them were quantified by ultra high pressure chromatography (UPLC) with quadruple and time-of-flight mass spectrometry (Q/TOF, TQ-S). Lipophilic CO 2 extracts were rich in tocopherols (2.36-10.07mg/g), while rosmarinic acid was dominating compound (up to 30mg/g) in ethanolic extracts. Apigenin-7-O-β-d-glucuronide, caffeic and carnosic acids were quantitatively important phytochemicals in the majority other Salvia spp. Antioxidatively active constituents were determined by using on-line high-performance liquid chromatography (HPLC) analysis combined with 2,2'-diphenyl-1-picrylhydrazyl (DPPH) assay (HPLC-DPPH). Development of high pressure isolation process and comprehensive characterisation of phytochemicals in Salvia spp. may serve for their wider applications in functional foods and nutraceuticals.

  16. A general method for identifying major hybrid male sterility genes in Drosophila.

    The genes responsible for hybrid male sterility in species crosses are usually identified by introgressing chromosome segments, monitored by visible markers, between closely related species by continuous backcrosses. This commonly used method, however, suffers from two problems. First, it relies on the availability of markers to monitor the introgressed regions and so the portion of the genome examined is limited to the marked regions. Secondly, the introgressed regions are usually large and it is impossible to tell if the effects of the introgressed regions are the result of single (or few) major genes or many minor genes (polygenes). Here we introduce a simple and general method for identifying putative major hybrid male sterility genes which is free of these problems. In this method, the actual hybrid male sterility genes (rather than markers), or tightly linked gene complexes with large effects, are selectively introgressed from one species into the background of another species by repeated backcrosses. This is performed by selectively backcrossing heterozygous (for hybrid male sterility gene or genes) females producing fertile and sterile sons in roughly equal proportions to males of either parental species. As no marker gene is required for this procedure, this method can be used with any species pairs that produce unisexual sterility. With the application of this method, a small X chromosome region of Drosophila mauritiana which produces complete hybrid male sterility (aspermic testes) in the background of D. simulans was identified. Recombination analysis reveals that this region contains a second major hybrid male sterility gene linked to the forked locus located at either 62.7 +/- 0.66 map units or at the centromere region of the X chromosome of D. mauritiana.

    Sperm morphology is still a standard laboratory analysis in diagnosing infertility in men. Manually identification of sperm form is still not accurate, the difficulty in seeing the form of the invisible sperm from the digital microscope image is often a weakness in the process of identification and takes a long time. Therefore, male fertility identification application system is needed Through sperm abnormalities based on sperm morphology (teratospermia). The method used is invariant moment method. This study uses 15 data testing and 20 data training sperm image. That the process of male fertility identification through sperm abnormalities based on sperm morphology (teratospermia) has an accuracy rate of 80.77%. Use of time to process Identification of male fertility through sperm abnormalities Based on sperm morphology (teratospermia) during 0.4369 seconds.

    Screening for male-derived biological material from collected samples plays an important role in criminal investigations, especially those involving sexual assaults. We have developed a loop-mediated isothermal amplification (LAMP) assay targeting multi-repeat sequences of the Y chromosome for detecting male DNA. Successful amplification occurred with 0.5 ng of male DNA under isothermal conditions of 61 to 67 °C, but no amplification occurred with up to 10 ng of female DNA. Under the optimized conditions, the LAMP reaction initiated amplification within 10 min and amplified for 20 min. The LAMP reaction was sensitive at levels as low as 1-pg male DNA, and a quantitative LAMP assay could be developed because of the strong correlation between the reaction time and the amount of template DNA in the range of 10 pg to 10 ng. Furthermore, to apply the LAMP assay to on-site screening for male-derived samples, we evaluated a protocol using a simple DNA extraction method and a colorimetric intercalating dye that allows detection of the LAMP reaction by evaluating the change in color of the solution. Using this protocol, samples of male-derived blood and saliva stains were processed in approximately 30 min from DNA extraction to detection. Because our protocol does not require much hands-on time or special equipment, this LAMP assay promises to become a rapid and simple screening method for male-derived samples in forensic investigations.

    Full Text Available According to WHO statistics 40 % of childless marriage is due to factors of male infertility. One of them is the presence of antisperm antibodies in the male organism, which may be in blood serum, on the surface of spermatozoids and seminal plasma. Aim. Оn the grounds of specialized literature analysis, to show the relevance of this problem in Reproductive Medicine, to descript Basic methods of Modern treatment and diagnosis of this pathology in the body of infertile males. The most common methods of antisperm antibodies identifying are: MAR-test sample Shuvarskiy–Sims–Hyuner, Kurtsrok–Miller test, the method of latex agglutination, solid-phase immunoenzymatic blood test. Indications for antisperm antibodies determining are: modified indices, deviations in post-coital test, a negative test of sperm and cervical mucus interaction in vitro, unexplained infertility in the married couples, failure or low indices during IVF (in vitro fertilization and of course, the exclusion of other causes of infertility. When antisperm antibodies are detected, the strategy of treatment may be destined to reduction of their titer for further pregnancy. Such types of therapy can be used: contraceptive (long-term use contraception barrier to reduce antisperm antibodies titer in women, plasmapheresis, artificial insemination with pretreated from antisperm antibodies husband's sperm, methods of assisted reproductive technologies.

    To evaluate whether single-entry endoscopic vasectomy of male feral pigeons (Columba livia) significantly reduced fertility and would potentially be valuable for control of feral pigeon populations, 252 male feral pigeons were caught in the city of Berne and endoscopically vasectomized. In this procedure, approximately 1 cm of the deferent duct was removed bilaterally. Rapid, uneventful recoveries occurred in 94% (237/252) of the pigeons, whereas 6% (15/252) died because of complications associated with the procedure, consisting of perforation of the ureter (9/15), major hemorrhage (5/15), and respiratory arrest (1/15). Mean anesthesia time was 23±6 minutes. The vasectomized males were habituated to 2 pigeon houses together with fertile females. Another pigeon house with fertile pairs acted as control. All eggs laid were candled weekly to assess fertility. In the 2 pigeon houses with vasectomized males, the mean fertilization rate was 0.9% (5/563), while in the control pigeon house, the rate was 100% (39/39). The results indicate that endoscopic vasectomy of male feral pigeons may be a promising tool for field control of feral pigeon populations, especially in combination with other methods such as pigeon houses.

    Full Text Available Microalbuminuria is associated with hypertension and is a strong risk factor for subsequent chronic disease, both renal and coronary heart disease (CHD, Presently there are several methods available for measurement of microalbuminuria. The aim of this study was to evaluate if the three different methods gave similar information or if one of the assays were superior to the others. Blood pressure, inflammatory markers and cardiovascular mortality and morbidity were correlated with urine albumin analysed with a point-of-care testing (POCT instrument, nephelometric determination of albumin and albumin/creatinine ratio in elderly males. The study population consisted of 103 diabetic and 603 nondiabetic males (age 77 years in a cross-sectional study. We analyzed urine albumin with a HemoCue® Urine Albumin POCT instrument and a ProSpec® nephelometer and albumin/creatinine ratio. There were strong correlations between both systolic and diastolic blood pressure and all three urine albumin methods (p < 0.0001. There were also significant correlations between the different urine albumin measurements and serum amyloid A component, high-sensitivity C-reactive protein and interleukin-6. The three different urine albumin methods studied provided similar information in relation to cardiovascular disease. There was a strong correlation between systolic and diastolic blood pressure and microalbuminuria in both the whole study population and in nondiabetic males emphasizing the role of hypertension in glomerular damage. The good correlation between the studied urine albumin measurements show that all three methods can be used for monitoring urine albumin excretion.

    The hepatic cytochrome P450 enzymes play a central role in the biotransformation of endogenous and exogenous substances. A sensitive high-throughput liquid chromatography with tandem mass spectrometry assay was developed and validated for the simultaneous quantification of the products of ten metabolic reactions catalyzed by hepatic cytochrome P450 enzymes. After the substrates were incubated separately, the samples were pooled and analyzed by liquid chromatography with tandem mass spectrometry using an electrospray ionization source in the positive and negative ion modes. The method exhibited linearity over a broad concentration range, insensitivity to matrix effects, and high accuracy, precision, and stability. The novel method was successfully applied to study the kinetics of phenacetin-O deethylation, coumarin-7 hydroxylation, bupropion hydroxylation, taxol-6 hydroxylation, omeprazole-5 hydroxylation, dextromethorphan-O demethylation, tolbutamide-4 hydroxylation, chlorzoxazone-6 hydroxylation, testosterone-6β hydroxylation, and midazolam-1 hydroxylation in rat liver microsomes. © 2015 WILEY-VCH Verlag GmbH & Co.

    Golden Anne L.

    1999-01-01

    Full Text Available Concerns that chemical exposures in the environment have been detrimental to male sexual development and fertility have been heightened by reports of declining sperm counts over the past 50 years. Marked geographic variation has been found in semen quality and in the incidence of testicular cancer and certain urogenital defects. Debate continues over the existence, magnitude and significance of these trends, and how best to evaluate the hypothesis that in utero and childhood exposures to estrogenic compounds may be to blame. Epidemiologic methods for assessing the impact of hazardous substances on male reproductive health have been developed mainly in the area of occupational medicine, and this paper will review the currently recommended methods. These include questionnaires to determine reproductive history and sexual function; reproductive hormone profiles; and semen analyses such as sperm concentration, motility, and morphology. New research tools that show significant promise from the fields of clinical reproductive medicine and reproductive toxicology are discussed as possible additions to epidemiologic studies, including assays of sperm function and genetic integrity, and biomarkers of DNA damage. For population-based studies involving occupational groups or communities with environmental exposures, issues related to the cost, validity, precision and utility of these methods must be carefully considered.

    The aim of this study was to evaluate the perception of androstenone in pork from entire male pigs with different androstenone levels (High≥2mgkg -1 ; Medium 0.5-0.7mgkg -1 ) applying four different heating methods (vacuum, grill, oven and frying). Androstenone (AND) perception was analysed during and after cooking by a trained panel. During cooking, the highest score for AND odour (greatest perception) was obtained with the grill and vacuum, while frying was the best option for reducing its perception, which was judged to be imperceptible for androstenone medium level (Pperception, making it the best option for reducing both AND odour and flavour. In short, the use of different heating methods strongly affected AND perception. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The results are presented of nuclear geochronological datings of Male Karpaty Mts. granitoids by Rb-Sr isochrone method. Using the method the age of Bratislava massif granitoids was established to be 347+-4 mil. y. at ( 87 Sr/ 86 Sr)=0.7076+-0.0013 and the age of Modra massif granitoids to be 324+-18 mil. y. at ( 87 Sr/ 86 Sr)=0.7075+-0.00032 (2σ). The relative agreement of age of both massifs as well as the agreement of the primary ratio ( 87 Sr/ 86 Sr) 0 not only testifies to their continuity in age but also in genesis. The same relations also confirm the genetic dependence of pegmatites and leucocratic granitoids on fundamental types of granitoids building up the Bratislava and Modra massifs. (author)

    Full Text Available Ao longo dos anos, os programas de planejamento familiar preocuparam-se quase que exclusivamente em atingir apenas a população feminina. Mais recentemente essa atitude vem mudando, pois evidenciou-se que os homens têm forte influência sobre suas parceiras quanto ao uso de anticoncepcionais. Dentro deste contexto, a presente pesquisa teve como objetivo geral identificar a perspectiva e o papel masculino quanto à decisão de usar métodos contraceptivos. O tamanho amostral foi calculado em 776 homens de uma universidade paulista; foram selecionados 467 estudantes de graduação, 314 funcionários e 129 docentes, totalizando 910 sujeitos. Foi utilizado um questionário estruturado e pré-testado. A análise dos dados encontra-se em andamento. Os métodos menos conhecidos pelos homens foram: Billings (29,9%, injetáveis (35,4% e os cremes/geléias (57,8%. Os demais foram mencionados por pelo menos 80% dos entrevistados. A proporção dos que disseram não conhecer qualquer meio de evitar a gravidez esteve em torno de 1,6%. Estes resultados são semelhantes aos encontrados por outros autores.Historically, family planning programs have targeted women almost exclusively. More recently it has become clear that men have a strong influence on their partners' use of contraception, either by opposing the use of any or one specific method, or by deciding that a woman has to either use a given method or be sterilized. In this context, our study aimed to evaluate the male perspective on the role of gender in the decision to use contraceptive methods and to have and raise children. The sample consisted of 776 males from a university in the State of São Paulo: 467 graduate students, 314 employees, and 129 teachers. A structured, previously tested questionnaire was used for the interviews. Data analysis is currently under way. The least familiar contraceptive methods were Billings (29.9%, injectables (35.4%, and jellies (57.8%. Some 80% of the interviewees

    Multidirectional communicative interactions in social networks can have a profound effect on mate choice behavior.Male Atlantic molly Poecilia mexicana exhibit weaker mating preferences when an audience male is presented.This could be a male strategy to reduce sperm competition risk:interacting more equally with different females may be advantageous because rivals might copy mate choice decisions.In line with this hypothesis,a previous study found males to show a strong audience effect when being observed while exercising mate choice,but not when the rival was presented only before the choice tests.Audience effects on mate choice decisions have been quantified in poeciliid fishes using association preference designs,but it remains unknown if patterns found from measuring association times translate into actual mating behavior.Thus,we createl five audience treatments simulating different forms of perceived sperm competition risk and determined focal males' mating preferences by scoring pre-mating (nipping) and mating behavior (gonopodial thrusting).Nipping did not reflect the pattern that was found when association preferences were measured,while a very similar pattern was uncovered in thrusting behavior.The strongest response was observed when the audience could eavesdrop on the focal male's behavior.A reduction in the strength of focal males' preferences was also seen after the rival male had an opportunity to mate with the focal male's preferred mate.In comparison,the reduction of mating preferences in response to an audience was greater when measuring association times than actual mating behavior.While measuring direct sexual interactions between the focal male and both stimulus females not only the male's motivational state is reflected but also females' behavior such as avoidance of male sexual harassment [Current Zoology 58 (1):84-94,2012].

    Full Text Available Collecting accurate and reliable nutritional data from adolescent populations is challenging, with current methods providing significant under-reporting. Therefore, the aim of the study was to determine the accuracy of a combined dietary data collection method (self-reported weighed food diary, supplemented with a 24-h recall when compared to researcher observed energy intake in male adolescent soccer players. Twelve Academy players from an English Football League club participated in the study. Players attended a 12 h period in the laboratory (08:00 h–20:00 h, during which food and drink items were available and were consumed ad libitum. Food was also provided to consume at home between 20:00 h and 08:00 h the following morning under free-living conditions. To calculate the participant reported energy intake, food and drink items were weighed and recorded in a food diary by each participant, which was supplemented with information provided through a 24-h recall interview the following morning. Linear regression, limits of agreement (LOA and typical error (coefficient of variation; CV were used to quantify agreement between observer and participant reported 24-h energy intake.

    Enlisting male partner involvement is perceived as an important component of women's successful uptake of female-initiated HIV prevention methods. We conducted a longitudinal study among a cohort of 955 Zimbabwean women participating in a clinical trial of the effectiveness of a female-initiated HIV prevention method (the diaphragm and lubricant gel) to: (a) describe the extent to which women involved their male partners in the decision to use the study products, and (b) measure the effect perceived male partner support had on their acceptability and consistent use of these methods. Reported levels of male partner involvement in discussions and decisions regarding: joining the study, study activities, the outcome of HIV/STI test results, and product use were very high. In multivariate analyses, regular disclosure of study product use and partner approval for the diaphragm and gel were significantly associated with women's acceptability and consistent use of the products; an essential component for determining efficacy of investigational prevention methods. These results support the need for more sophisticated measurement of how couples interact to make decisions that impact study participation and investigational product use as well as more rigorous adaptations and evaluations of existing strategies to involve male partners in female-initiated HIV prevention trials.

    Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The idea for the film appears to have come from the 1957 book Cosmic View by Kees Boeke. The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative pow...

    Full Text Available Multidirectional communicative interactions in social networks can have a profound effect on mate choice behavior. Male Atlantic molly Poecilia mexicana exhibit weaker mating preferences when an audience male is presented. This could be a male strategy to reduce sperm competition risk: interacting more equally with different females may be advantageous because rivals might copy mate choice decisions. In line with this hypothesis, a previous study found males to show a strong audience effect when being observed while exercising mate choice, but not when the rival was presented only before the choice tests. Audience effects on mate choice decisions have been quantified in poeciliid fishes using association preference designs, but it remains unknown if patterns found from measuring association times translate into actual mating behavior. Thus, we created five audience treatments simulating different forms of perceived sperm competition risk and determined focal males’ mating preferences by scoring pre-mating (nipping and mating behavior (gonopodial thrusting. Nipping did not reflect the pattern that was found when association preferences were measured, while a very similar pattern was uncovered in thrusting behavior. The strongest response was observed when the audience could eavesdrop on the focal male’s behavior. A reduction in the strength of focal males’ preferences was also seen after the rival male had an opportunity to mate with the focal male’s preferred mate. In comparison, the reduction of mating preferences in response to an audience was greater when measuring association times than actual mating behavior. While measuring direct sexual interactions between the focal male and both stimulus females not only the male’s motivational state is reflected but also females’ behavior such as avoidance of male sexual harassment [Current Zoology 58 (1: 84–94, 2012].

    Full Text Available The habit of smoking white cigarettes and clove cigarettes may affect the gustatory function, that is, it will cause damage to taste buds, resulting in an increase in gustatory threshold. This research used the descriptive comparative method and had the purpose of obtaining an illustration of gustatory threshold and compare gustatory threshold in white cigarette smokers and clove cigarette smokers in young, male adults. For gustatory threshold evaluation, the Murphy method was used to obtain a value for perception threshold and taste identification threshold using sucrose solution of 0.0006 M-0.06 M concentration. Research results indicate that the perception threshold and identification threshold of young, male adult smokers are 0.0119 M and 0.0292 M. Young, male adult clove cigarette smokers have a perception threshold and identification threshold of 0.0151 M and 0.0348 M. The conclusion of this research is that the perception threshold of young, male adult white cigarette smokers and clove cigarette smokers are the same, whereas the identification threshold of young, male adult white cigarette smokers and clove cigarette smokers are different, that is, the identification threshold of clove cigarette smokers is higher than that of white cigarette smokers.

    In Korean culture, the names of family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is shown here that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that for married women entering a collection of family books in a certain year, the occurrence of the most common family name 'Kim' should be directly proportional to the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to a high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to the year 500 AD, based on the RGF model, and find about ten thousand Kims.

    Full Text Available Sampling the biodiversity is an essential step for conservation, and understanding the efficiency of sampling methods allows us to estimate the quality of our biodiversity data. Sex ratio is an important population characteristic, but until now, no study has evaluated how efficient are the sampling methods commonly used in biodiversity surveys in estimating the sex ratio of populations. We used a virtual ecologist approach to investigate whether active and passive capture methods are able to accurately sample a population's sex ratio and whether differences in movement pattern and detectability between males and females produce biased estimates of sex-ratios when using these methods. Our simulation allowed the recognition of individuals, similar to mark-recapture studies. We found that differences in both movement patterns and detectability between males and females produce biased estimates of sex ratios. However, increasing the sampling effort or the number of sampling days improves the ability of passive or active capture methods to properly sample sex ratio. Thus, prior knowledge regarding movement patterns and detectability for species is important information to guide field studies aiming to understand sex ratio related patterns.

    Dispersive liquid-liquid microextraction (DLLME) sample preparation and the quick, easy, cheap, effective, rugged and safe (QuEChERS) method combined with DLLME were developed and compared for the analysis of ten pyrethroids in various fruit juices using gas chromatography-electron capture detection (GC-ECD). QuEChERS-DLLME method has found its widespread applications to all the fruit juices including those samples with more complex matrices (orange, lemon, kiwi and mango) while DLLME was confined to the fruit juices with simpler matrices (apple, pear, grape and peach). The two methods provided acceptable recoveries and repeatability. In addition, the applicabilities of two methods were demonstrated with the real samples and further confirmed by gas chromatography-mass spectrometry (GC-MS). Copyright © 2014.

    Full Text Available The aim of our present work was the development of a rapid high-performance liquid chromatography method with electrospray ionization and tandem mass spectrometry detection (LC-ESI-MS/MS for the determination of several corticosteroids in cosmetic products. Corticosteroids are suspected to be illegally added in cosmetic preparations in order to enhance the curative effect against some skin diseases. Sample preparation step consists in a single extraction with acetonitrile followed by centrifugation and filtration. The compounds were separated by reversed-phase chromatography with water and acetonitrile (both with 0.1% formic acid gradient elution and detected by ESI-MS positive and negative ionization mode. The method was validated at the validation level of 0.1 mg kg−1. Linearity was studied in the 5–250 μg L−1 range and linear coefficients (r2 were all over 0.99. The accuracy and precision of the method were satisfactory. The LOD ranged from 0.085 to 0.109 mg kg−1 and the LOQ from 0.102 to 0.121 mg kg−1. Mean recoveries for all the analytes were within the range 91.9–99.2%. The developed method is sensitive and useful for detection, quantification, and confirmation of these corticosteroids in cosmetic preparations and can be applied in the analysis of the suspected samples under investigation.

    Interventions have been carried out to improve the reproductive health and status of women in Turkey. However, these efforts are limited due to lack of male involvement. Lifestyle risks such as partner violence need to be evaluated in terms of any effects on the use of contraception. Data collected from interviews of married women and their husbands for the 1998 Turkish Demographic and Health Survey and 1971 husbands were included in the study. The percentage of husbands who were against partner violence was 20.4%. However, 22 (0.9%) husbands had an attitude toward the use of violence against their wives. The frequency of contraceptive use was increased from the group of men who had unfavorable attitudes towards violence to the group of men who had favorable attitudes. A similar trend was found in the percentages of condom use for men, with multiple factors influencing contraceptive use. The study suggests that further investigations are needed for couple-related issues to improve the status of women in the community and to empower women for sexual health.

    Although female contraceptives are very effective at preventing unintended pregnancy, some women can not use them because of health conditions or side-effects, leaving some couples without effective contraceptive options. In addition, many men wish to take active responsibility for family planning. Thus, there is a great need for male contraceptives to prevent unintended pregnancies, of which 80-90 million occur annually. At present, effective male contraceptive options are condoms and vasectomy, which are not ideal for all men. Therefore, efforts are under way to develop novel male contraceptives. This paper briefly reviews the advantages and disadvantages of condoms and vasectomies and then discusses the research directed toward development of novel methods of male contraception.

  14. Home cage wheel running is an objective and clinically relevant method to assess inflammatory pain in male and female rats

    2016-01-01

    Background The assessment of nociception in preclinical studies is undergoing a transformation from pain-evoked to pain-depressed tests to more closely mimic the effects of clinical pain. Many inflammatory pain-depressed behaviors (reward seeking, locomotion) have been examined, but these tests are limited because of confounds such as stress and difficulties in quantifying behavior. New Method The present study evaluates home cage wheel running as an objective method to assess the magnitude and duration of inflammatory pain in male and female rats. Results Injection of Complete Freund’s Adjuvant (CFA) into the right hindpaw to induce inflammatory pain almost completely inhibited wheel running for 2 days in males and females. Wheel running gradually returned to baseline levels within 12 days despite persistent mechanical hypersensitivity (von Frey test). Comparison with Existing Methods Continuously monitoring home cage wheel running improves on previous studies examining inflammatory pain-depressed wheel running because it is more sensitive to noxious stimuli, avoids the stress of removing the rat from its cage for testing, and provides a complete analysis of the time course for changes in nociception. Conclusions The present data indicate that home cage wheel running is a clinically relevant method to assess inflammatory pain in the rat. The decrease in activity caused by inflammatory pain and subsequent gradual recovery mimics the changes in activity caused by pain in humans. The tendency for pain-depressed wheel running to be greater in female than male rats is consistent with the tendency for women to be at greater risk of chronic pain than men. PMID:26891874

    Objective: “History, Theory, Ethics of Medicine” (German: “Geschichte, Theorie, Ethik der Medizin”, abbreviation: GTE) forms part of the obligatory curriculum for medical students in Germany since the winter semester 2003/2004. This paper presents the results of a national survey on the contents, methods and framework of GTE teaching. Methods: Semi-structured questionnaire dispatched in July 2014 to 38 institutions responsible for GTE teaching. Descriptive analysis of quantitative data and content analysis of free-text answers. Results: It was possible to collect data from 29 institutes responsible for GTE teaching (response: 76%). There is at least one professorial chair for GTE in 19 faculties; two professorial chairs or professorships remained vacant at the time of the survey. The number of students taught per academic year ranges from 350. Teaching in GTE comprises an average of 2.18 hours per week per semester (min: 1, max: 6). Teaching in GTE is proportionally distributed according to an arithmetic average as follows: history: 35.4%, theory 14.7% and ethics 49.9%. Written learning objectives were formulated for GTE in 24 faculties. The preferred themes of teaching in history, theory or ethics which according to respondents should be taught comprise a broad spectrum and vary. Teaching in ethics (79 from a max. of 81 possible points) is, when compared to history (61/81) and theory (53/81), attributed the most significance for the training of medical doctors. Conclusion: 10 years after the introduction of GTE the number of students and the personnel resources available at the institutions vary considerably. In light of the differences regarding the content elicited in this study the pros and cons of heterogeneity in GTE should be discussed. PMID:28584871

We developed a novel method to measure the occlusive force exerted over the perineal arteries and determined perineal artery occlusion by a variety of seat designs. Methods. Doppler ultrasonography facilitated perineal artery localization and determination of the force required for perineal artery occlusion in 20 healthy men. Flexiforce(®) sensors were affixed over the proximal and distal aspects of the perineal arteries bilaterally. Individuals completed bicycle rides in the road- and stationary-settings with six distinct seat designs, including those with and without an anterior "nose." Results. The occlusion time proportion of the total ride time was calculated for each trial. The overall occlusion time proportion was 0.59 (95% CI [0.45-0.73]) across all seats and settings. The "no-nose" bicycle seat and the stationary-setting demonstrated significantly lower occlusion proportion times than the traditional nose bicycle seat and road-setting, respectively. However, all bicycle seats yielded an occlusion time proportion of 0.41 or greater. Discussion. Our method of real-time, non-invasive force measurement localized to the perineal arteries may be used to validate future bicycle seat design. It also underscores the significant risk of perineal artery insufficiency in men who are avid bicyclists. This risk may be minimized by using newer "no-nose" bicycle seats.

    Full Text Available The aim of present study was to evaluate the iodine/iodide status in biological samples (serum and urine of 172 male hypothyroid patients (HPs and their supplemental effects on thyroid hormones. For comparison purpose, non-goitrous subjects (n= 220 of same age group and socioeconomic status were also studied. A simple and rapid iodide-ion selective electrode (ISE was used to measure the concentration of iodine in microwave assisted acid digested serum and urine samples. Quality control for the methodology was established with certified samples and with those obtained by conventional wet acid digestion method on the same certified reference materials (CRMs and real samples. A linear calibration curve was obtained for a reasonable concentration range of the potassium iodide solutions. The mean concentration of iodine in the serum and urine samples of the HPs was significantly reduced as compared to control male subjects (p< 0.01. The low levels of free triiodothyronine and thyroxin were found in HPs than age matched healthy control (p< 0.005 and 0.002 respectively while high levels of thyroid stimulating hormone were observed in HPs (p< 0.008. The proposed method was relatively efficient as well as cost effective by using inexpensive equipment. It was observed that iodine in biological samples of HPs can play an important role in determining the severity of the hypothyroidism.

    The aim of present study was to evaluate the iodine/iodide status in biological samples (serum and urine) of 172 male hypothyroid patients (HPs) and their supplemental effects on thyroid hormones. For comparison purpose, non-goitrous subjects (n= 220) of same age group and socioeconomic status were also studied. A simple and rapid iodide-ion selective electrode (ISE) was used to measure the concentration of iodine in microwave assisted acid digested serum and urine samples. Quality control for the methodology was established with certified samples and with those obtained by conventional wet acid digestion method on the same certified reference materials (CRMs) and real samples. A linear calibration curve was obtained for a reasonable concentration range of the potassium iodide solutions. The mean concentration of iodine in the serum and urine samples of the HPs was significantly reduced as compared to control male subjects (p< 0.01). The low levels of free triiodothyronine and thyroxin were found in HPs than age matched healthy control (p< 0.005 and 0.002) respectively while high levels of thyroid stimulating hormone were observed in HPs (p< 0.008). The proposed method was relatively efficient as well as cost effective by using inexpensive equipment. It was observed that iodine in biological samples of HPs can play an important role in determining the severity of the hypothyroidism. (author)

    The purpose of this study was to evaluate transcutaneous electrical nerve stimulation (TENS) and other common treatment methods used in the process of wound healing in terms of the expression levels of pro-inflammatory cytokines. In the study, 24 female and 24 male adult Wistar-Albino rats were divided into five groups: (1) the non-wounded group having no incision wounds, (2) the control group having incision wounds, (3) the TENS (2 Hz, 15 min) group, (4) the physiological saline (PS) group and (5) the povidone iodine (PI) group. In the skin sections, interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were assessed with enzyme-linked immunosorbent assay and immunohistochemical methods. In the non-wounded group, the expression of IL-1β, IL-6, and TNF-α signaling molecules was weaker in the whole tissue; however, in the control group, significant inflammatory response occurred, and strong cytokine expression was observed in the dermis, granulation tissue, hair follicles, and sebaceous glands (P TENS group, the decrease in TNF-α, IL-1β, and IL-6 immunoreaction in the skin was significant compared to the other forms of treatment (P TENS group suggest that TENS shortened the healing process by inhibating the inflammation phase.

    Metoidioplasty presents one of the variants of phalloplasty in female transsexuals. Urethral lengthening is the most difficult part in this surgery and poses many challenges. We evaluated 207 patients who underwent metoidioplasty, aiming to compare two different surgical techniques of urethral lengthening, postoperative results, and complications. The study encompassed a total of 207 patients, aged from 18 to 62 years, who underwent single stage metoidioplasty between September 2002 and July 2011. The procedure included lengthening and straightening of the clitoris, urethral reconstruction, and scrotoplasty with implantation of testicular prostheses. Buccal mucosa graft was used in all cases for dorsal urethral plate formation and joined with one of the two different flaps: I-longitudinal dorsal clitoral skin flap (49 patients) and II-labia minora flap (158 patients). Results were analyzed using Z-test to evaluate the statistical difference between the two approaches. Also, postoperative questionnaire was used, which included questions on functioning and esthetical appearance of participating subjects as well as overall satisfaction. The median follow-up was 39 months (ranged 12-116 months). The total length of reconstructed urethra was measured during surgery in both groups. It ranged from 9.1 to 12.3 cm (median 9.5) in group I and from 9.4 to 14.2 cm (median 10.8) in group II. Voiding while standing was significantly better in group II (93%) than in group I (87.82%) (P lengthening confirmed combined buccal mucosa graft and labia minora flap as a method of choice for urethroplasty in metoidioplasty, minimizing postoperative complications. © 2013 International Society for Sexual Medicine.

    In southern Malawi, 12.8% of adults are HIV positive. Men are less likely to have been tested than women. We investigated men's HIV knowledge and the attitudes, influencers, facilitators and barriers affecting HIV testing. We conducted an explanatory mixed-methods study with analysis of secondary quantitative data from 425 rural men collected in January 2014 (time 1) and April 2015 (time 2) and qualitative interviews with 50 men in September 2015. All respondents lived in villages receiving HIV education and testing. Quantitative data revealed that comprehensive HIV knowledge increased and was associated with having been tested by time 2. Educational level was positively associated with having been tested. Men's reasons for not getting tested were fear of learning their HIV status, fear of rejection by partners and wives and fear of discrimination. Wives influenced men's opinions about healthcare. The qualitative results demonstrated that men feared being seen at test sites and feared discrimination. Wives had the greatest reported influence on male testing. Men perceived services as female-oriented and stigmatizing. They preferred door-to-door testing. Providers can improve uptake by increasing men's HIV knowledge, leveraging the influence of spouses and offering door-to-door testing with male health workers. © The Author(s) 2017.

    Carbon tetrachloride (CCl 4 ) is a well-known model compound for producing chemical hepatic injury. Cytochrome P450 is an important monooxygenase in biology. We investigated the CYP450 protein expression in the in vivo hepatotoxicity of rats induced by CCl 4 . In this experiment, CCl 4 were administered to male rats, and their livers at 24 h post-dosing were applied to the proteomic analysis. Blood biochemistry and histopathology were examined to identify specific changes. At the same time, a novel acetylation stable isotopic labeling method coupled with LTQ-FTICR mass spectrometry was applied to disclose the changes of cytochrome P450 expression amounts. The quantitative proteomics method demonstrated its correlation coefficient was 0.9998 in a 100-fold dynamic range and the average ratio of the labeled peptides was 1.04, which was very close to the theoretical ratio of 1.00 and the standard deviation (S.D.) of 0.21. With this approach, 17 cytochrome P450 proteins were identified and quantified with high confidence. Among them, the expression amount of 2C11, 3A2, and 2 E1 were down-regulated, while that of 2C6, 2B2, and 2B1 were up-regulated

    Full Text Available Treatment of male urethral trauma is always a challenging problem. In China, as the incidence of urethral trauma keeps rising, more and more studies relating to this are being published. To compare the outcome of different emergency treatments in China and other countries, we searched Chinese and English literature about this topic in the past 16 years. A total of 167 studies involving 5314 patients were included, with 144 in Chinese and 23 in English. All studies were retrospective in nature. Based on the analyses, surgical methods include open realignment, endoscopic realignment and primary repair, and we summarized and compared the success rate and complications (mainly erectile dysfunction and incontinence of each method. We found that realignment of posterior urethra has similar success rate in China and other countries, but the outcome of realignment of anterior urethra is variable. The reason remains unknown. While long abandoned in Western countries, primary repair of anterior urethra is still an option in China and has high success rate.

    Transcutaneous electrical nerve stimulation (TENS) is an electrophysical modality used for pain management. This study investigated the dose response of different TENS intensities on experimentally induced pressure pain. One hundred and thirty TENS naïve healthy individuals (18-64 years old; 65 males, 65 females) were randomly allocated to 5 groups (n = 26 per group): Strong Non Painful TENS; Sensory Threshold TENS; Below Sensory Threshold TENS; No Current Placebo TENS; and Transient Placebo TENS. Active TENS (80 Hz) was applied to the forearm for 30 minutes. Transient Placebo TENS was applied for 42 seconds after which the current amplitude automatically reset to 0 mA. Pressure pain thresholds (PPT) were recorded from 2 points on the hand and forearm before and after TENS to measure hypoalgesia. There were significant differences between groups at both the hand and forearm (ANOVA; P = .005 and .002). At 30 minutes, there was a significant hypoalgesic effect in the Strong Non Painful TENS group compared to: Below Sensory Threshold TENS, No Current Placebo TENS and Transient Placebo TENS groups (P TENS and No Current Placebo TENS groups at the hand (P = .001). There was no significant difference between Strong Non Painful TENS and Sensory Threshold TENS groups. The area under the curve for the changes in PPT significantly correlated with the current amplitude (r(2) = .33, P = .003). These data therefore show that there is a dose-response effect of TENS with the largest effect occurring with the highest current amplitudes. This study shows a dose response for the intensity of TENS for pain relief with the strongest intensities showing the greatest effect; thus, we suggest that TENS intensity should be titrated to achieve the strongest possible intensity to achieve maximum pain relief.

    The study purpose was to determine relationships between results of internal and external match load determining methods. Twenty-one players, who participated in selected badminton championships during the 2014/2015 season served as subjects. The heart rate (HR) values and GPS data of each player were obtained via a fix Polar HR Transmitter Belt and MinimaxX GPS device. Moderate significant Spearman's rank correlations were found between HR and absolute duration (r = 0.43 at a low intensity (LI) and 0.44 at a high intensity (HI)), distance covered (r = 0.42 at a HI) and player load (PL) (r = 0.44 at a HI). Results also revealed an opposite trend for external and internal measures of load as the average relative HR value was found to be the highest for the HI zone (54.1%) compared to the relative measures of external load where average values (1.29-9.89%) were the lowest for the HI zone. In conclusion, our findings show that results of an internal and external badminton match load determining method are more related to each other in the HI zone than other zones and that the strength of relationships depend on the duration of activities that are performed in especially LI and HI zones. Overall, trivial to moderate relationships between results of an internal and external match load determining method in male, singles badminton players reaffirm the conclusions of others that these constructs measure distinctly different demands and should therefore be measured concurrently to fully understand the true requirements of badminton match play.

    2014-01-01

    Background Transcutaneous nerve stimulation (TENS) has been proposed as a means of reducing pain in labour. The TENS unit emits low-voltage electrical impulses which vary in frequency and intensity. During labour, TENS electrodes are generally placed on the lower back, although TENS may be used to stimulate acupuncture points or other parts of the body. The physiological mechanisms whereby TENS relieves pain are uncertain. TENS machines are frequently operated by women, which may increase a sense of control in labour. Objectives To assess the effects of TENS on pain in labour. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (30 April 2011) and reference lists of retrieved papers. Selection criteria Randomised controlled trials comparing women receiving TENS for pain management in labour versus routine care, alternative non-pharmacological methods of pain relief, or placebo devices. We included all types of TENS machines. Data collection and analysis Two review authors assessed for inclusion all trials identified by the search strategy, carried out data extraction and assessed risk of bias. We have recorded reasons for excluding studies. Main results Seventeen trials with 1466 women contribute data to the review. Thirteen examined TENS applied to the back, two to acupuncture points, and two to the cranium. Overall, there was little difference in pain ratings between TENS and control groups, although women receiving TENS to acupuncture points were less likely to report severe pain (average risk ratio 0.41, 95% confidence interval 0.31 to 0.54; measured in two studies). The majority of women using TENS said they would be willing to use it again in a future labour. Where TENS was used as an adjunct to epidural analgesia there was no evidence that it reduced pain. There was no consistent evidence that TENS had any impact on interventions and outcomes in labour. There was little information on outcomes for mothers and babies. No

    Transcutaneous electric nerve stimulation (TENS) is a non-pharmacological method which is widely used by medical and paramedical professionals for the management of acute and chronic pain in a variety of conditions. Similarly, it can be utilized for the management of pain during various dental procedures as well as pain due to various conditions affecting maxillofacial region. This review aims to provide an insight into clinical research evidence available for the analgesic and non analgesic uses of TENS in pediatric as well as adult patients related to the field of dentistry. Also, an attempt is made to briefly discuss history of therapeutic electricity, mechanism of action of TENS, components of TENs equipment, types, techniques of administration, advantages and contradictions of TENS. With this we hope to raise awareness among dental fraternity regarding its dental applications thereby increasing its use in dentistry. Key words:Dentistry, pain, TENS.

    2016-10-01

    Full Text Available Objective(s: Sugar cane molasses is a commonly used ingredient in several food products. Contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. However, little evidence exists that examines the effects of molasses on the different physiological systems. This study investigated the effects of sugar cane molasses on various physiological systems using in vivo and in vitro methods. Materials and Methods: Molasses was administered orally to BALB/c, male mice and animals were randomly assigned into either a treatment or control group. General physiological changes, body weight and molasses intake of animals were monitored. At the end of the exposure period, collected blood samples were evaluated for potential toxicity using plasma biomarkers and liver enzyme activity. Immunised treated and untreated mice were evaluated for antibody titre to determine the effect of molasses on the immune response. To investigate the impact of molasses on testicular steroidogenesis, testes from both treated and control groups were harvested, cultured and assayed for testosterone synthesis.  Results: Findings suggest that fluid intake by molasses-treated animals was significantly increased and these animals showed symptoms of loose faeces. Molasses had no significant effect on body weight, serum biomarkers or liver enzyme activity (P>0.05.  Immunoglobulin-gamma anti-antigen levels were significantly suppressed in molasses-treated groups (P=0.004. Animals subjected to molasses exposure also exhibited elevated levels of testosterone synthesis (P=0.001. Conclusion: Findings suggests that molasses adversely affects the humoral immune response. The results also promote the use of molasses as a supplement to increase testosterone levels.

    Background: Baby-friendly Hospital Initiative (BFHI) is a vital intervention supported by World Health Organization and UNICEF to reduce infant mortality and has been included as a part of the curriculum in nursing and medical courses. To know the extent of knowledge of students about BFHI along with its understanding and to find out the gap in their knowledge about BFHI steps. Methods: A descriptive cross sectional study was carried out among the nursing (4th year) and medical students (3rd year MBBS) about ten steps of BFHI by a pretested and predesigned questionnaire. After ethical clearance, information was collected about their awareness and correct understanding concerning ten steps. Results: A total of 102 (51.6%) medical and 96 (48.4%) nursing students comprising of 57 (28.8%) males and 141 (71.2%) females were interviewed, had similar mean score about the ten steps of BFHI. Female respondents 82.3% had best understood the step 2 (training), as compared to males 80.7%. About step 6 (no supplements) 94.3% females and 86% males had well understood the step. Step 7 (rooming in) was known to 85.8% females and 54.4% males respectively. Step 9 (no pacifiers) was known to 80.1% females while among males 56.1% were aware. There was statistically significant difference in their knowledge about the steps 2 and 4 (skin to skin), 5 (counseling), 7, and 9 as females were more aware about these steps than males. The least understood steps in medical and nursing students were step 1 (written policy) (15.7%, 15.6%), step 3 (prenatal education) (27.5%, 29.2%), step 8 (cues) (10.8%, 24%) and step ten (community support) (8.8%, 11.5%) respectively. Conclusions: BFHI is one of the successful international efforts undertaken to promote, protect and support breast feeding. Acquiring knowledge about the same by medical and nursing students is most crucial tool for better practices by them in the future.

    The purpose of the study is to determine and compare the hydration status with different methods and determine fluid intake, dehydration percentages and sweat rate of 26 young male soccer players (15 ± 1.2 years) before an important competition. More specifically, the study aims at validating the urine strip and advising the players to use it as an easy and practical method. Measurements of urine analysis were taken from the urine sample of the participants before breakfast and conducted for 3 consecutive days before the competition. Hydration status was assessed through analysis of urine color, urine specific gravity (USG) (laboratory, strip, refractometry), and osmolality. The players' dehydration percentages and sweat ratio were calculated. The average values for all samples were 3 ± 1 for color, and 1.021 ± 4 g/cm(3) for USG (laboratory), and 1.021 ± 3 g/cm(3) for USG (strip), and 1.021 ± 4 for USG (refractometry), and 903 ± 133 mOsm/kg for osmolality. USG (strip) was highly correlated with USG (laboratory), USG (refractometry) (r = 0.8; P soccer players were observed as 0.5 % and 582.3 ± 232.0 mL/h, respectively. We found that youth soccer players are under a slight risk of dehydration under moderate weather conditions. As indicated by the research results, determination of hydration status of athletes must be taken into account more carefully under moderate and hot weather conditions. In addition, hydration methods were compatible with one another as measured in this study.

    A mixture of two selenium-containing compounds, 80 wt. % AS657 and 20 wt. % AS620, are studied with two complementary methods, electric-field-induced birefringence (EFIB) and microbeam resonant x-ray scattering (μRXS). The mixture shows the typical phase sequence of Sm-C_{A}^{*}-1/3-1/2-Sm-C^{*}-Sm-C_{α}^{*}-Sm-A, where 1/3 and 1/2 are two prototypal ferrielectric and antiferroelectric subphases with three- and four-layer unit cells, respectively. Here we designate the subphase as its q_{T} number defined by the ratio of [F]/([F]+[A]), where [F] and [A] are the numbers of synclinic ferroelectric and anticlinic antiferroelectric orderings in the unit cell, respectively. The electric field vs temperature phase diagram with EFIB contours indicates the emergence of three additional subphases, an antiferroelectric one between Sm-C_{A}^{*} and 1/3 and antiferroelectric and apparently ferrielectric ones between 1/3 and 1/2. The simplest probable q_{T}'s for these additional subphases are 1/4, 2/5, and 3/7, respectively, in the order of increasing temperature. The μRXS profiles indicate that antiferroelectric 1/4 and 2/5 approximately have the eight-layer (FAAAFAAA) and ten-layer (FAFAAFAFAA) Ising unit cells, respectively. The remaining subphase may be ferrielectric 3/7 with a seven-layer unit cell, although the evidence is partial. These experimental results are compared with the phenomenological Landau model [P. V. Dolganov and E. I. Kats, Liq. Cryst. Rev. 1, 127 (2014)2168-039610.1080/21680396.2013.869667] and the quasimolecular model [A. V. Emelyanenko and M. A. Osipov, Phys. Rev.

    This report documents the authors work as an expert team advising the US Department of Energy on modes of inadvertent intrusion over the next 10,000 years into the Waste Isolation Pilot Project (WIPP) nuclear waste repository. Credible types of potential future accidental intrusion into the WIPP are estimated as a basis for creating warning markers to prevent inadvertent intrusion. A six-step process is used to structure possible scenarios for such intrusion, and it is concluded that the probability of inadvertent intrusion into the WIPP repository over the next ten thousand years lies between one and twenty-five percent. 3 figs., 5 tabs

    A new pictorial assessment was developed to measure aggression-supportive cognitions among young aggressive male students. The assessment was comprised of 17 watercolor ambiguous sketches that could be interpreted in either an aggressive or a benign manner (e.g., two young people facing each other with their arms folded). The results showed that high trait aggressive male students were more likely to make hostile attributions of the pictures, providing significantly more themes of entitlement and power in the stories they generated about the pictures. Aggressive male students also endorsed significantly more aggression-supportive cognitions on a self-report measure and provided some supporting qualitative accounts of physically aggressive encounters. The results of this study are discussed and evaluated with reference to future work with young violent adolescents.

  7. Ten years of nuclear power

    Ten years have elapsed since the world's first nuclear power station began to supply electricity in Russia, and this in turn marked the end of a twelve year stage following the first controlled nuclear chain reaction at Chicago. These periods mark major stages in the development of atomic energy from the realm of abstract ideas to that of everyday industrial application. They followed a period of fundamental research and laboratory work, culminating in Enrico Fermi's demonstration of a system whereby the forces of the atom could be brought under control. Then it was necessary to find ways and means of using the chain reaction for practical purposes and on an industrial scale. And after this had been shown in 1954 to be technically possible, it had still to be developed into an economic process. The nuclear power station has proved itself from the technical and engineering standpoint. The third phase of development has been to bring it to the stage of being economically competitive with alternative sources of energy, and it would appear that we are now reaching that goal - though more slowly than had been envisaged ten years ago

    With the appearance of nano-science the role of local methods has become more and more important. Hard x-ray holography based on the inside reference point concept is a local probe of the atomic order in solids. It gives the 3D real space image of atoms without the phase ambiguity inherent to diffraction methods. In this paper a brief description of the basics of hard x-ray holography is given. The last ten years' experimental and evaluation-related developments are reviewed. We also introduce different variants of the method, such as Bremsstrahlung and gamma ray holography (GRH). The power of the method is illustrated by examples. We outline new directions and future possibilities. (authors)

    Full Text Available Objectives: The aim of present study was to determine the effectiveness of conceptual map training method on the achievement of social-economic skill course in male students with intellectual disability. Methods: This study was semi-experimental and 34 male students with intellectual disability who were educating in 3rd grade at pre-professional level in high school selected randomly from Talash Exceptional Center in Tabriz City. Their academic achievement in social-economic skill course were assessed by teacher-made and performance tests. Subjects were assigned in control and experimental groups randomly and equally. Experimental group participated in 8 sessions and were trained by conceptual map method for one month (8 sessions 2 sessions weekly. At the end of eightieth session and one month later, subjects answered to teacher-made and performance tests again. Data were analyzed by analysis of covariance. Results: Findings showed that the conceptual map training method had positive effect on achievement of social-economic skill in students (P<0.01. But, its effectiveness wasn’t persistent after one month in follow-up test. Discussion: Regarding to positive effects of conceptual map training method on meaningful learning, it seems as an effective method for intellectually disabled male students who require deep learning to understand the content of their lessons.

    Human body finite element models (FEMs) are a valuable tool in the study of injury biomechanics. However, the traditional model development process can be time-consuming. Scaling and morphing an existing FEM is an attractive alternative for generating morphologically distinct models for further study. The objective of this work is to use a radial basis function to morph the Global Human Body Models Consortium (GHBMC) average male model (M50) to the body habitus of a 95th percentile male (M95) and to perform validation tests on the resulting model. The GHBMC M50 model (v. 4.3) was created using anthropometric and imaging data from a living subject representing a 50th percentile male. A similar dataset was collected from a 95th percentile male (22,067 total images) and was used in the morphing process. Homologous landmarks on the reference (M50) and target (M95) geometries, with the existing FE node locations (M50 model), were inputs to the morphing algorithm. The radial basis function was applied to morph the FE model. The model represented a mass of 103.3 kg and contained 2.2 million elements with 1.3 million nodes. Simulations of the M95 in seven loading scenarios were presented ranging from a chest pendulum impact to a lateral sled test. The morphed model matched anthropometric data to within a rootmean square difference of 4.4% while maintaining element quality commensurate to the M50 model and matching other anatomical ranges and targets. The simulation validation data matched experimental data well in most cases.

A batch of 10 superconducting decapole magnets for the LHC has just arrived at CERN from India. These will be used to correct for slight imperfections in the dipole magnets that will steer proton beams around CERN's new accelerator. All magnets have slight imperfections in the fields they produce, and in the LHC dipoles these will be corrected for using sextupoles and decapoles. The sextupoles were the first LHC magnets to be given the production green-light following successful tests of pre-series magnets last year (Bulletin 21/2000, 22 May 2000). Now it is the turn of pre-series decapoles to go on trial at CERN. Of the LHC's 1232 dipole magnets, half will use sextupole correctors only and the other half will use both sextupoles and decapoles. That means that a total of 616 pairs of decapoles are needed. Like the sextupole...

    Thirty male Wistar rats, split into five groups of six rats each, were administered different forms of oil palm tree (Elaeis guineensis) sap samples by gavage based on 1.5% of their weekly body weights. Group 1 which served as control received only water, group 2 received pasteurized palm sap (PPS), group 3 received market palm wine (MPW), group 4 received frozen palm sap (FPS), whereas group 5 received fresh palm sap (FrPS). Chemical composition of the sap samples was determined. Normal feed and water were fed ad libitum. After 2 months of treatment, each male rat group was allowed 7 days to mate with six female Wistar rats. Thereafter, blood and epididymal samples were collected for testosterone assay and sperm count, respectively, before they were humanely sacrificed and testicular tissues taken for testicular histology. Litter weight and size of the pups produced by the females of each group were determined at birth. The sap samples contained carbohydrate (0.01-11.71%), protein (1.56-1.95%), ash (0.22-0.35%), moisture (92.55-98.24%), and alcohol (0.26-3.50%). PPS-treated rat group had significantly (Psap, impacted negatively on the reproductive indices of male animals.

    Background Female sex workers (FSWs) may benefit from pre-exposure prophylaxis (PrEP) including microbicides for HIV prevention. Since adherence is a key factor in PrEP efficacy, we explored microbicide acceptability and potential barriers to use within FSWs’ intimate relationships in Tijuana and Ciudad Juárez, Mexico, where HIV prevalence is increasing. Methods FSWs and their verified intimate (non-commercial) male partners completed quantitative and qualitative interviews from 2010–2012. Our complementary mixed methods design followed an iterative process to assess microbicide acceptability, explore related relationship dynamics, and identify factors associated with concern about male partners’ anger regarding microbicide use. Results Among 185 couples (n=370 individuals), interest in microbicides was high. In qualitative interviews with 28 couples, most participants were enthusiastic about microbicides for sex work contexts but some explained that microbicides could imply mistrust/infidelity within their intimate relationships. In the overall sample, nearly 1 in 6 participants (16%) worried that male partners would become angry about microbicides, which was associated with higher self-esteem among FSWs and lower self-esteem and past year conflict causing injury within relationships among men. Conclusions HIV prevention interventions should consider intimate relationship dynamics posing potential barriers to PrEP acceptability and adherence, involve male partners, and promote risk communication skills.

  16. Resolution 1540, ten years on

    2014-06-01

    Adopted on the 28 April 2004 by the United Nations Security Council under Chapter VII of the UN Charter, Resolution 1540 is a composite tool that was hitherto unprecedented. To recap, States are bound to 'refrain from providing any form of support to non-State actors that attempt to develop, acquire, manufacture, possess, transport, transfer or use nuclear, chemical or biological weapons and their means of delivery' (par. 1), and to prohibit and prevent non-State actors from the aforementioned through 'appropriate and effective' (par. 2,3) legal, judiciary, and administrative means. A Committee was established to which States had to submit a first report outlining the steps 'they have taken or intend to take to implement this resolution' (par. 4). This Committee was initially established for two years and has been regularly renewed since, and its mandate was extended in 2011 for ten years. It is not a surveillance mechanism. Finally, with the aim of remedying difficulties that certain States may experience in implementing the Resolution, 'States in a position to do so' are invited to offer assistance (par. 7). The level of the application of Resolution 1540 was originally based on a delicate three-pronged balance of obligation, good will, and partnership. It is not a matter of designating certain States to the rest of the international community, whilst avoiding that the exercise be limited to the submission of national reports, instead aiming to initiate a dynamic. The wager was a risky one. Ten years on, 90% of UN member States have submitted one or several implementation reports. 170 States and 50 international and regional organisations have taken part in outreach and implementation support events. Whatever quantitative or qualitative conclusions that can be reached, we should continue to promote the Re-solution's universal adoption, and to ensure that the implementation of its provisions is undertaken in a lasting manner, taking account of the national

    This paper proposes a profiling method for the tool which generates the helical groove of male rotor, screw compressor component. The method is based on a complementary theorem of surfaces enveloping - "Substitute Family Circles Method”. The specific theorem of family circles of substitution has been applied using AUTOCAD graphics design environment facility. The frontal view of the male rotor, screw compressor component, has been determinate knowing the transverse profile of female rotor, and using this theorem of "Substitute Family Circle". The three-dimensional model of the rotor makes possible to apply the same theorem, leading to the surface of revolution enveloping the helical surface. An application will be also presented to determine the axial profile of the disk cutter, numeric and graphics, following the proposed algorithm.

    Neuropathic pain, which is due to nerve disease or damage, represents a significant burden on people and society. It can be particularly unpleasant and achieving adequate symptom control can be difficult. Non-pharmacological methods of treatment are often employed by people with neuropathic pain and may include transcutaneous electrical nerve stimulation (TENS). This review supersedes one Cochrane Review 'Transcutaneous electrical nerve stimulation (TENS) for chronic pain' (Nnoaham 2014) and one withdrawn protocol 'Transcutaneous electrical nerve stimulation (TENS) for neuropathic pain in adults' (Claydon 2014). This review replaces the original protocol for neuropathic pain that was withdrawn. To determine the analgesic effectiveness of TENS versus placebo (sham) TENS, TENS versus usual care, TENS versus no treatment and TENS in addition to usual care versus usual care alone in the management of neuropathic pain in adults. We searched CENTRAL, MEDLINE, Embase, PsycINFO, AMED, CINAHL, Web of Science, PEDro, LILACS (up to September 2016) and various clinical trials registries. We also searched bibliographies of included studies for further relevant studies. We included randomised controlled trials where TENS was evaluated in the treatment of central or peripheral neuropathic pain. We included studies if they investigated the following: TENS versus placebo (sham) TENS, TENS versus usual care, TENS versus no treatment and TENS in addition to usual care versus usual care alone in the management of neuropathic pain in adults. Two review authors independently screened all database search results and identified papers requiring full-text assessment. Subsequently, two review authors independently applied inclusion/exclusion criteria to these studies. The same review authors then independently extracted data, assessed for risk of bias using the Cochrane standard tool and rated the quality of evidence using GRADE. We included 15 studies with 724 participants. We found a

    We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

  1. The PrePex device is unlikely to achieve cost-savings compared to the forceps-guided method in male circumcision programs in sub-Saharan Africa.

    Walter Obiero

    Full Text Available Male circumcision (MC reduces the risk of heterosexual HIV acquisition in men by approximately 60%. MC programs for HIV prevention are currently being scaled-up in fourteen countries in sub-Saharan Africa. The current standard surgical technique for MC in many sub-Saharan African countries is the forceps-guided male circumcision (FGMC method. The PrePex male circumcision (PMC method could replace FGMC and potentially reduce MC programming costs. We compared the potential costs of introducing the PrePex device into MC programming to the cost of the forceps-guided method.Data were obtained from the Nyanza Reproductive Health Society (NRHS, an MC service delivery organization in Kenya, and from the Kenya Ministry of Health. Analyses are based on 48,265 MC procedures performed in four Districts in western Kenya from 2009 through 2011. Data were entered into the WHO/UNAIDS Decision Makers Program Planning Tool. The tool assesses direct and indirect costs of MC programming. Various sensitivity analyses were performed. Costs were discounted at an annual rate of 6% and are presented in United States Dollars.Not including the costs of the PrePex device or referral costs for men with phimosis/tight foreskin, the costs of one MC surgery were $44.54-$49.02 and $54.52-$55.29 for PMC and FGMC, respectively.The PrePex device is unlikely to result in significant cost-savings in comparison to the forceps-guided method. MC programmers should target other aspects of the male circumcision minimum package for improved cost efficiency.

  3. Compactified vacuum in ten dimensions

    International Nuclear Information System (INIS)

    Wurmser, D.

    1987-01-01

    Since the 1920's, theories which unify gravity with the other fundamental forces have called for more than the four observed dimensions of space-time. According to such a theory, the vacuum consists of flat four-dimensional space-time described by the Minkowski metric M 4 and a compactified space B. The dimensions of B are small, and the space can only be observed at distance scales smaller than the present experimental limit. These theories have had serious difficulties. The equations of gravity severely restrict the possible choices for the space B. The allowed spaces are complicated and difficult to study. The vacuum is furthermore unstable in the sense that a small perturbation causes the compactified dimensions to expand indefinitely. There is an addition a semi-classical argument which implies that the compactified vacuum by annihilated by virtual black holes. It follows that a universe with compactified extra dimensions could not have survived to the present. These results were derived by applying the equations of general relativity to spaces of more than four dimensions. The form of these equations was assumed to be unchanged by an increase in the number of dimensions. The authors illustrate the effect of such terms by considering the example B = S 6 where S 6 is the six-dimensional sphere. Only when the extra terms are included is this choice of the compactified space allowed. He explore the effect of a small perturbation on such a vacuum. The ten-dimensional spherically symmetric potential is examined, and I determine conditions under which the formation of virtual black holes is forbidden. The examples M 4 x S 6 is still plagued by the semi-classical instability, but this result does not hold in general. The requirement that virtual black holes be forbidden provides a test for any theory which predicts a compactified vacuum

    Intestinal stomas have a major impact on Cases' lives. It is essential to better understand the areas in which interventions may help to minimize the negative consequences. This was a case-control survey study using validated instruments (City of Hope Quality of Life-Ostomy and Short Form 36 for Veterans). Cases were accrued from Veterans Affairs Medical Centers in Tucson, Indianapolis, and Los Angeles. Eligibility included a major intra-abdominal surgical procedure that led to an ostomy (cases), or a similar procedure that did not mandate a stoma (controls). Analysis included quantitative and qualitative responses. The response rate was 48 percent (511/1,063). Cases and controls had relatively similar demographic characteristics. Because of low numbers of female respondents (13 cases and 11 controls), only results for males are reported. Based on both the City of Hope Quality of Life-Ostomy and Short Form 36 for Veterans, cases reported significantly poorer scores on scales/domains reflecting psychologic and social functioning and well being. Additionally, cases reported poorer scores on Short Form 36 for Veterans scales reflecting physical functioning and significantly lower scores on multiple items in the social domain of the City of Hope Quality of Life-Ostomy compared with controls. Two-thirds of cases replied to an open-ended question on their "greatest challenge" related to their ostomy, which led to further clarification of major issues. Multiple health-related quality of life problems were reported by male veterans with intestinal stomas. The greatest differences between cases and controls were observed in the social and psychologic domains/scales. Findings from this study provide a greater understanding of the challenges faced by ostomates and will inform the development and evaluation of urgently needed intervention strategies.

    Full Text Available Estimating the age distribution of mosquito populations is crucial for assessing their capacity to transmit disease and for evaluating the efficacy of available vector control programs. This study reports on the capacity of the near-infrared spectroscopy (NIRS technique to rapidly predict the ages of the principal dengue and Zika vector, Aedes aegypti. The age of wild-type males and females, and males and females infected with wMel and wMelPop strains of Wolbachia pipientis were characterized using this method. Calibrations were developed using spectra collected from their heads and thoraces using partial least squares (PLS regression. A highly significant correlation was found between the true and predicted ages of mosquitoes. The coefficients of determination for wild-type females and males across all age groups were R2 = 0.84 and 0.78, respectively. The coefficients of determination for the age of wMel and wMelPop infected females were 0.71 and 0.80, respectively (P< 0.001 in both instances. The age of wild-type female Ae. aegypti could be identified as < or ≥ 8 days old with an accuracy of 91% (N = 501, whereas female Ae. aegypti infected with wMel and wMelPop were differentiated into the two age groups with an accuracy of 83% (N = 284 and 78% (N = 229, respectively. Our results also indicate NIRS can distinguish between young and old male wild-type, wMel and wMelPop infected Ae. aegypti with accuracies of 87% (N = 253, 83% (N = 277 and 78% (N = 234, respectively. We have demonstrated the potential of NIRS as a predictor of the age of female and male wild-type and Wolbachia infected Ae. aegypti mosquitoes under laboratory conditions. After field validation, the tool has the potential to offer a cheap and rapid alternative for surveillance of dengue and Zika vector control programs.

    There are several studies that showed the high prevalence of high-risk sexual behaviors among youths, but little is known how significant the proportion of higher risk sex is when the male and female youths are compared. A meta-analysis was done using 26 countries' Demographic and Health Survey data from and outside Africa to make comparisons of higher risk sex among the most vulnerable group of male and female youths. Random effects analytic model was applied and the pooled odds ratios were determined using Mantel-Haenszel statistical method. In this meta-analysis, 19,148 male and 65,094 female youths who reported to have sexual intercourse in a 12-month period were included. The overall OR demonstrated that higher risk sex was ten times more prevalent in male youths than in female youths. The practice of higher risk sex by male youths aged 15-19 years was more than 27-fold higher than that of their female counterparts. Similarly, male youths in urban areas, belonged to a family with middle to highest wealth index, and educated to secondary and above were more than ninefold, eightfold and sixfold at risk of practicing higher risk sex than their female counterparts, respectively. In conclusion, this meta-analysis demonstrated that the practice of risky sexual intercourse by male youths was incomparably higher than female youths. Future risky sex protective interventions should be tailored to secondary and above educated male youths in urban areas.

    The presented study aimed to evaluate the selenium and zinc status of Korean middle -aged male patients with CHD. The serum concentration of zinc and selenium was measured by Neutron activation analysis method. The mean serum selenium and zinc concentrations of patients were 94.9 μg/l and 826.4 μg/l, respectively compared to the 97.8μg/l, 891.6 μg/l of control group, showing no any difference in selenium status, but showed significant difference for zinc status of middle -aged men. The deficiency of zinc in control group was 9.8%, but that was 31.3% in patient group. Conclusively, this study indicated that zinc status, which is associated with inflammatory reaction, is low in Korean male patients with CHD

    Male pattern baldness or androgenetic alopecia is a common disorder affecting almost 50% of men throughout their lifetime, with androgens and genetics having significant contributing aetiologies. In contrast to the positive regulatory effect of androgens on body hair growth, they are thought to alter scalp hair follicle behaviour pathophysiologically, leading to male pattern baldness. However, the exact mechanisms of this paradoxical action have not yet been elucidated. The role of microRNAs, a novel group of noncoding RNAs impacting almost every aspect of biology, health and human diseases, has been documented in hair follicle formation. In addition, their deregulation in cancer of the prostate, a target organ of androgens, has also been well established. To investigate the possible contribution of microRNAs in the pathophysiology of male pattern baldness. We initially screened microRNA expression profiles of balding and nonbalding hair follicle papillae with a sensitive microRNA cloning method, microRNA amplification profiling, and statistically analysed significant differentially expressed microRNAs in balding relative to nonbalding dermal papillae, with real-time polymerase chain reaction as a confirmatory method to quantify expression in eight individuals affected with the disorder.   We detected the significant upregulation of miR-221, miR-125b, miR-106a and miR-410 in balding papilla cells.   We found four microRNAs that could participate in the pathogenesis of male pattern baldness. Regarding the strong therapeutic potential of microRNAs and the easy accessibility of hair follicles for gene therapy, microRNAs are possible candidates for a new generation of revolutionary treatments. © 2011 The Authors.

  12. Ten years of effective multilateralism?

    International Nuclear Information System (INIS)

    Hautecouverture, Benjamin

    2013-12-01

    successes of multilateralism and international law provide security assurances or do they mask the flaws of an insufficiently intrusive system? While the U.S. signaled their defiance under the guidance of John Bolton, European thinking settled on a conclusion with the air of a slogan: yes to multilateralism, providing it is effective. This was to be the cornerstone of the policies to undertake and the instruments to implement to forge a global role for the Union. Its originality is based simultaneously in realism and in a refusal to resort to force as the foremost means of action on the international stage. Another way of defining the 2003 Strategy is a skillful compromise between differing positions to banish the Iraqi 'cacophony' as quickly as possible. Ten years on, it is now time for 'impact assessments' and other 'scorecards' of public policies. In the midst of the Eurozone economic crisis, evaluating a strategy of 'effective multilateralism' is not easy. The Union's bi-annual reports on its implementation have recently begun to try to provide a quantitative analysis that is not entirely convincing (for instance, the number of ratifications of such-and-such an instrument with regard to the budget allocated by the EU to facilitate its universalization, over such-and-such a period). Fundamentally, the 2003 Strategy is essentially beyond this kind of analysis even if it can prove useful. The strength of the European approach consists in establishing a long-term willingness to maintain and strengthen collective security tools approved by the greatest possible number of States. Its weakness is to occasionally confront a strategic reality that is as contradictory as it is stubborn. Effective multilateralism is linked to voluntarism and vows. (author)

  13. Demand for male contraception.

    2012-10-01

    The biological basis for male contraception was established decades ago, but despite promising breakthroughs and the financial burden men increasingly bear due to better enforcement of child support policies, no viable alternative to the condom has been brought to market. Men who wish to control their fertility must rely on female compliance with contraceptives, barrier methods, vasectomy or abstinence. Over the last 10 years, the pharmaceutical industry has abandoned most of its investment in the field, leaving only nonprofit organisations and public entities pursuing male contraception. Leading explanations are uncertain forecasts of market demand pitted against the need for critical investments to demonstrate the safety of existing candidate products. This paper explores the developments and challenges in male contraception research. We produce preliminary estimates of potential market size for a safe and effective male contraceptive based on available data to estimate the potential market for a novel male method.

    Rodent euthanasia using exposure to increasing concentrations of CO2 has come under scrutiny due to concerns of potential pain during the euthanasia process. Alternatives to CO2, such as isoflurane and barbiturates, have been proposed as more humane methods of euthanasia. In this study, we examined 3 commonly used euthanasia methods in mice: intraperitoneal injection of pentobarbital–phenytoin solution, CO2 inhalation, and isoflurane anesthesia followed by CO2 inhalation. We hypothesized that pentobarbital–phenytoin euthanasia would cause fewer alterations in cardiovascular response, result in less behavioral evidence of pain or stress, and produce lower elevations in ACTH than would the isoflurane and CO2 methods, which we hypothesized would not differ in regard to these parameters. ACTH data suggested that pentobarbital–phenytoin euthanasia may be less stressful to mice than are isoflurane and CO2 euthanasia. Cardiovascular, behavioral, and activity data did not consistently or significantly support isoflurane or pentobarbital–phenytoin euthanasia as less stressful methods than CO2. Euthanasia with CO2 was the fastest method of the 3 techniques. Therefore, we conclude that using CO2 with or without isoflurane is an acceptable euthanasia method. Pathologic alterations in the lungs were most severe with CO2 euthanasia, and alternative euthanasia techniques likely are better suited for studies that rely on analysis of the lungs. PMID:28905718

    It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

    Full Text Available  Aim: To investigate the changes in a training hospital’s surgical patient profile in ten years. To delineate the effects of the transfer of Social Security Institution Hospitals to the Ministry of Health on this process. Material and Method: Ten-year apart, two-year periods were selected and all elective and emergency cases were retrospectively searched. In between periods, the hospital was transferred from Social Security Institution Hospital to the Ministry of Health and then became a trauma center. The indications, techniques, the number of performed surgeries, and the patient related factors were compared. The ratio of the number emergency cases and the number of cases performed by residents in training to the total number of cases were investigated. Results: The number of elective and emergent operations during the former and the latter periods were 2668 and 2041, respectively. The percentage of the decrease was 23.5%. After ten years, the patients were younger, more commonly male, emergency cases were more common, and operations performed primarily by the residents in training were less frequent than the former period (p<0,05. Oncological surgery of stomach, colon-rectum, breast, thyroid and primary-metastatic-malign carcinoma were more frequent during former period whereas urgent operations except peptic ulcer perforation and upper gastrointestinal bleeding and benign anorectal diseases were more common during later period (p<0,05. Discussion: The comparison revealed a significant decrease in the number of operations in ten years. The number of oncological patients increased whereas the number of emergency cases declined. The changes were thought to be related more to the transition in health and becoming a trauma center than to major developments in the country and the world.

    The purpose of this study was to develop a method for applying calibrated manual massage pressures by using commonly available, inexpensive sphygmomanometer parts and validate the use of this approach as a quantitative method of applying massage therapy to rodents. Massage pressures were monitored by using a modified neonatal blood pressure (BP) cuff attached to an aneroid gauge. Lightly anesthetized rats were stroked on the ventral abdomen for 5 minutes at pressures of 20 mm Hg and 40 mm Hg. Blood pressure was monitored noninvasively for 20 minutes following massage therapy at 5-minute intervals. Interexaminer reliability was assessed by applying 20 mm Hg and 40 mm Hg pressures to a digital scale in the presence or absence of the pressure gauge. With the use of this method, we observed good interexaminer reliability, with intraclass coefficients of 0.989 versus 0.624 in blinded controls. In Long-Evans rats, systolic BP dropped by an average of 9.86% ± 0.27% following application of 40 mm Hg massage pressure. Similar effects were seen following 20 mm Hg pressure (6.52% ± 1.7%), although latency to effect was greater than at 40 mm Hg. Sprague-Dawley rats behaved similarly to Long-Evans rats. Low-frequency/high-frequency ratio, a widely-used index of autonomic tone in cardiovascular regulation, showed a significant increase within 5 minutes after 40 mm Hg massage pressure was applied. The calibrated massage method was shown to be a reproducible method for applying massage pressures in rodents and lowering BP. Copyright © 2016. Published by Elsevier Inc.

    This paper is an effort to summarize the way Slovak Bohunice NPP has gone through since the historical change in the Middle and Eastern European countries. Milestones on the way were: 1989 - change of political system; increasing interest of the public appearance; creation of work capacities - personnel and technical; education/exchange with Western countries; 1994 - establishment of Foreign Affairs and PR Department reporting directly to the NPP manager; application of various approaches, some observed from other countries; creation of utility policy - place of PR in the company; establishment of QA system - description of PR activities, goals, interlinks etc.; annual planning process including activities, finance, education (training). Lessons learned are: the NPP managers were not prepared; the public was not (and still is not) prepared to obtain specific information; education is crucial in opinion winning; simple overtake of methods from others is not always applicable; strategy and feedback are necessary. Special case was the early closure Bohunice V1 NPP

    Male baldness is very common. Its effect on individuals is extremely variable, and in some people it will have a significant adverse effect on their quality of life. The objectives of this article are to help general practitioners (GPs) be aware of potential health problems related to male baldness, to have an approach to assessing hair loss and to be aware of treatment options. Male baldness is, most often, a normal occurrence, but it may have significant effects on a man's health. It may also be a pointer to other potential health issues. The GP is in the ideal position to conduct an initial evaluation, consider other health issues and advise on treatment options.

    Ability to influence household decision-making has been shown to increase with improved social capital and power and is linked to better access to household financial resources and other services outside the household including healthcare. To examine the male-female differences in household custody of financial resources, decision-making, and type of healthcare utilised, we used a mixed methods approach of cross-sectional household surveys and focus-group discussions (FGDs). Data was collected between 10 January-28 February 2011. We analyzed a sample of 411 households and a sub-sample of 223 households with a currently married head. We conducted six single-sex FGDs in 3 communities (1 urban, 2 rural) among a random sub-sample of participants in the survey. We performed univariate, bivariate, and logistic regression analyses with a 95% confidence interval. For the qualitative data, we performed thematic analysis where broad themes relevant to the research objective were abstracted. In all households and in those with a married head, sick male members were less likely to forgo healthcare (aOR all 0.87, 95% CI 0.80-0.90; aOR married 0.52, 95% CI 0.18-0.83) and more likely to utilise formal healthcare relative to female sick members (aOR all 3.36, 95% CI 3.20-3.87; aOR married 19.50, 95% CI 9.62-39.52). Formal healthcare providers are medically trained while informal providers are untrained vendors that dispense medications for profit. There were more reports of sole custody of household resources among men within households with married heads. Joint decision-making on healthcare expenditure improved women's access to healthcare but is not reflective of unhindered access to household financial resources. Qualitatively, women spoke of seeking permission from male household head before expenditure was incurred, while male heads spoke of concealing household financial resources from their spouse. Gender constructs and male-female differences have important effects on

    Background and aims Research into work addiction has steadily grown over the past decade. However, the literature is far from unified and there has been much debate on many different issues. Aim and methods This paper comprises a narrative review and focuses on 10 myths about work addiction that have permeated the psychological literature and beyond. The 10 myths examined are (a) work addiction is a new behavioral addiction, (b) work addiction is similar to other behavioral addictions, (c) there are only psychosocial consequences of work addiction, (d) work addiction and workaholism are the same thing, (e) work addiction exclusively occurs as a consequence of individual personality factors, (f) work addiction only occurs in adulthood, (g) some types of work addiction are positive, (h) work addiction is a transient behavioral pattern related to situational factors, (i) work addiction is a function of the time spent engaging in work, and (j) work addiction is an example of overpathogizing everyday behavior and it will never be classed as a mental disorder in the DSM. Results Using the empirical literature to date, it is demonstrated that there is evidence to counter each of the 10 myths. Conclusion It appears that the field is far from unified and that there are different theoretical constructs underpinning different strands of research.

    Suicide attempts and suicides constitute a significant burden on communities and health systems, especially in low income countries. However, many low income countries lack epidemiological information on which to base future preventive strategies. This study reports on gender and age profiles as well as the likely background and means used for suicide attempts and suicides in Bolivia. This study presents 1124 cases from four different sources of information: (i) emergency ward data with suicide attempts by poisoning from the year 2007, (ii) psychiatric ward data including suicide attempts from July 2011 to July 2012, (iii) newspaper articles reporting attempted suicides and suicides from 2009 to 2011, and (iv) the National Statistics on Crime reporting suicides from the years 2010-2011. Data on age was stratified into three age groups: adolescents aged 10-19 years, young adults aged 20-29 years, and older adults aged above 29 years. Data from the hospital wards and Crime Statistics were pooled to compare characteristics of suicide attempts with suicides concerning age and gender. Data on age, gender, methods used, and reasons were analyzed using IBM SPSS version 21. Hospital data showed that more females (403/657, 61%) than males (254/657, 39%) attempted suicide, and females attempted suicide at a younger age than males (pcommitted suicide, and furthermore it was most prevalent among young adults aged 20-29 years of both genders, as observed from the Crime Statistics. The dominant method was pesticide poisoning varying from 400 out of 657 (70.5%) of the hospital poisoning cases to 65 out of 172 (37.8%) of the newspaper cases. Newspaper data showed a higher mortality rate (65/77, 85.1%) among those using violent methods such as hanging and jumping compared to non-violent methods (43/84, 50.9%) such as ingesting chemicals and drugs (psuicide seemed to be hidden due to cultural and religious reasons.

    Recent astronomical observations indicate that the Universe is presently almost flat and undergoing a period of accelerated expansion. Basing on Einstein's general relativity all these observations can be explained by the hypothesis of a dark energy component in addition to cold dark matter (CDM). Because the nature of this dark energy is unknown, it was proposed some alternative scenario to explain the current accelerating Universe. The key point of this scenario is to modify the standard FRW equation instead of mysterious dark energy component. The standard approach to constrain model parameters, based on the likelihood method, gives a best-fit model and confidence ranges for those parameters. We always arbitrary choose the set of parameters which define a model which we compare with observational data. Because in the generic case, the introducing of new parameters improves a fit to the data set, there appears the problem of elimination of model parameters which can play an insufficient role. The Bayesian information criteria of model selection (BIC) is dedicated to promotion a set of parameters which should be incorporated to the model. We divide class of all accelerating cosmological models into two groups according to the two types of explanation acceleration of the Universe. Then the Bayesian framework of model selection is used to determine the set of parameters which gives preferred fit to the SNIa data. We find a few of flat cosmological models which can be recommend by the Bayes factor. We show that models with dark energy as a new fluid are favoured over models featuring a modified FRW equation

    [Purpose] The purpose of the present study was to confirm the relationships between shoulder strength (extensor strength and internal rotator strength) of the abducted position and swimming power during arm-only swimming. [Subjects and Methods] Fourteen healthy male collegiate swimmers participated in the study. Main measures were shoulder strength (strength using torque that was calculated from the upper extremity length and the isometric force of the abducted position) and swimming power. [Results] Internal rotation torque of the dominant side in the abducted external rotated position (r=0.85) was significantly correlated with maximum swimming power. The rate of bilateral difference in extension torque in the maximum abducted position (r=-0.728) was significantly correlated with the swimming velocity-to-swimming power ratio. [Conclusion] The results of this study suggest that internal rotator strength measurement in the abducted external rotated position and extensor strength measurement in the maximum abducted position are valid assessment methods for swimmers.

    The use of bulls rather than steers for beef production offers some considerable advantages; however, the eating quality of bull beef is an issue of marketing concern. This study assessed the physicochemical characteristics of young Holstein-Friesian (HF) bull and steer beef. Steer carcasses were suspended by the Achilles tendon (AS) and by pelvic suspension (PS). HF steer beef had higher redness, yellowness and chroma values, whereas bulls had higher ultimate pH and darker muscle. Warner-Bratzler shear force, cook loss at different ageing times, moisture, and insoluble and total collagen were higher for HF bull beef, whereas intramuscular fat, soluble collagen and collagen solubility were higher for steer beef. HF steer beef had a higher proportion of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA), whereas bull beef had higher proportions of polyunsaturated fatty acids (PUFA), PUFA/SFA and n-6/n-3 PUFA ratios. In comparison to AS, PS increased redness and chroma after 24 h blooming; PS improved tenderness up to 7 days of ageing and accelerated the ageing process. For young dairy cattle, steer beef would likely have superior eating quality but a relatively less favourable nutritional fatty acid profile to bull beef. Suspension method affected the tenderness and colour intensity of dairy steer beef at different ageing times. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

    The Tetrahedral Network(TEN) is a powerful 3-D vector structure in GIS, which has a lot of advantages such as simple structure, fast topological relation processing and rapid visualization. The difficulty of TEN application is automatic creating data structure. Al though a raster algorithm has been introduced by some authors, the problems in accuracy, memory requirement, speed and integrity are still existent. In this paper, the raster algorithm is completed and a vector algorithm is presented after a 3-D data model and structure of TEN have been introducted. Finally, experiment, conclusion and future work are discussed.

    Full Text Available Conducting mail surveys can result in nonresponse error, which occurs when the potential participant is unwilling to participate or impossible to contact. Nonresponse can result in a reduction in precision of the study and may bias results. The purpose of this paper is to describe and make readers aware of a top ten list of mailed survey problems affecting the response rate encountered over time with different research projects, while utilizing the Dillman Total Design Method. Ten nonresponse error problems were identified, such as inserter machine gets sequence out of order, capitalization in databases, and mailing discarded by postal service. These ten mishaps can potentiate nonresponse errors, but there are ways to minimize their frequency. Suggestions offered stem from our own experiences during research projects. Our goal is to increase researchers' knowledge of nonresponse error problems and to offer solutions which can decrease nonresponse error in future projects.

    As part of the regulatory approval process in Europe, comparison of endogenous soybean allergen levels between genetically engineered (GE) and non-GE plants has been requested. A quantitative multiplex analytical method using tandem mass spectrometry was developed and validated to measure 10 potential soybean allergens from soybean seed. The analytical method was implemented at six laboratories to demonstrate the robustness of the method and further applied to three soybean field studies across multiple growing seasons (including 21 non-GE soybean varieties) to assess the natural variation of allergen levels. The results show environmental factors contribute more than genetic factors to the large variation in allergen abundance (2- to 50-fold between environmental replicates) as well as a large contribution of Gly m 5 and Gly m 6 to the total allergen profile, calling into question the scientific rational for measurement of endogenous allergen levels between GE and non-GE varieties in the safety assessment.

    This study was initiated as a component of a larger undertaking designed to study bone healing in microgravity aboard the International Space Station (ISS). Spaceflight experimentation introduces multiple challenges not seen in ground studies, especially with regard to physical space, limited resources, and inability to easily reproduce results. Together, these can lead to diminished statistical power and increased risk of failure. It is because of the limited space, and need for improved statistical power by increasing sample size over historical numbers, NASA studies involving mice require housing mice at densities higher than recommended in the Guide for the Care and Use of Laboratory Animals (National Research Council, 2011). All previous NASA missions in which mice were co-housed, involved female mice; however, in our spaceflight studies examining bone healing, male mice are required for optimal experimentation. Additionally, the logistics associated with spaceflight hardware and our study design necessitated variation of density and cohort make up during the experiment. This required the development of a new method to successfully co-house male mice while varying mouse density and hierarchical structure. For this experiment, male mice in an experimental housing schematic of variable density (Spaceflight Correlate) analogous to previously established NASA spaceflight studies was compared to a standard ground based housing schematic (Normal Density Controls) throughout the experimental timeline. We hypothesized that mice in the Spaceflight Correlate group would show no significant difference in activity, aggression, or stress when compared to Normal Density Controls. Activity and aggression were assessed using a novel activity scoring system (based on prior literature, validated in-house) and stress was assessed via body weights, organ weights, and veterinary assessment. No significant differences were detected between the Spaceflight Correlate group and the

    Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological analgesic method used to control different types of pain. The aim of this study was to evaluate the effects of preoperative TENS on post inguinal hernia repair pain. This randomized, double-blind, placebo-controlled clinical trial was performed on 66 male patients with unilateral inguinal hernias who were admitted to the Shahid Beheshti hospital in Kashan, Iran, from April to October 2014. Participants were selected using a convenience sampling method and were assigned to intervention (n = 33) and control (n = 33) groups using permuted-block randomization. Patients in the intervention group were treated with TENS 1 hour before surgery, while the placebo was administered to patients in the control group. All of the patients underwent inguinal hernia repair by the Lichtenstein method, and pain intensity was evaluated at 2, 4, 6, and 12 hours after surgery using a visual analogue scale. Additionally, the amounts of analgesic administered by pump were calculated and compared between the two groups. The mean estimated postoperative pain intensity was 6.21 ± 1.63 in the intervention group and 5.45 ± 1.82 in the control group (P = 0.08). In the intervention group pain intensity at 2 and 4 hours after surgery were 3.54 ± 1.48 and 5.12 ± 1.41 (P TENS can reduce postoperative pain in the early hours after inguinal hernia repair surgery.

    Disorders of colonic motility may contribute to symptoms in patients with irritable bowel syndrome (IBS), and stress is widely believed to play a major role in developing IBS. Stress increases corticotropin releasing factor (CRF) of the hypothalamus, resulting in acceleration of colonic transit in rodents. In contrast, hypothalamic oxytocin (OXT) has an anti-stress effect via inhibiting CRF expression and hypothalamic-pituitary-adrenal axis activity. Although transcutaneous electrical nerve stimulation (TENS) and acupuncture have been shown to have anti-stress effects, the mechanism of the beneficial effects remains unknown. We tested the hypothesis that TENS upregulates hypothalamic OXT expression resulting in reduced CRF expression and restoration of colonic dysmotility in response to chronic stress. Male SD rats received different types of stressors for seven consecutive days (chronic heterotypic stress). TENS was applied to the bilateral hind limbs every other day before stress loading. Another group of rats did not receive TENS treatment. TENS significantly attenuated accelerated colonic transit induced by chronic heterotypic stress, which was antagonized by a central injection of an OXT antagonist. Immunohistochemical study showed that TENS increased OXT expression and decreased CRF expression at the paraventricular nucleus (PVN) following chronic heterotypic stress. It is suggested that TENS upregulates hypothalamic OXT expression which acts as an anti-stressor agent and mediates restored colonic dysmotility following chronic stress. TENS may be useful to treat gastrointestinal symptoms associated with stress.

    The present study was designed to investigate the bioactive constituents of Xanthoceras sorbifolia in terms of amounts and their antioxidant, DNA scission protection, and α-glucosidase inhibitory activities. Simultaneous quantification of 10 X. sorbifolia constituents was carried out by a newly established ultra-high performance liquid chromatography-quadrupole mass spectrometry method (UHPLC-MS). The antioxidant activities were evaluated by measuring DPPH radical scavenging and DNA scission protective activities. The α-glucosidase inhibitory activities were investigated by using an assay with α-glucosidase from Bacillus Stearothermophilus and disaccharidases from mouse intestine. We found that the wood of X. sorbifolia was rich in phenolic compounds with the contents of catechin, epicatechin, myricetin, and dihydromyricetin being 0.12-0.19, 1.94-2.16, 0.77-0.91, and 6.76-7.89 mg·g(-1), respectively. The four constituents strongly scavenged DPPH radicals (with EC50 being 4.2, 3.8 and 5.7 μg·mL(-1), respectively) and remarkably protected peroxyl radical-induced DNA strand scission (92.10%, 94.66%, 75.44% and 89.95% of protection, respectively, at a concentration of 10 μmol·L(-1)). A dimeric flavan 3-ol, epigallocatechin-(4β→8, 2β→O-7)-epicatechin potently inhibited α-glucosidase with an IC50 value being as low as 1.2 μg·mL(-1). The established UHPLC-MS method could serve as a quality control tool for X. sorbifolia. In conclusion, the high contents of antioxidant and α-glucosidase inhibitory constituents in X. sorbifolia support its use as complementation of other therapeutic agents for metabolic disorders, such as diabetes and hypertension.

    Full Text Available Although HIV disease stage at ART initiation critically determines ART outcomes, few reports have longitudinally monitored this within Asia. Using prospectively collected data from a large ART program at Sihanouk Hospital Center of Hope in Cambodia, we report on the change in patient characteristics and outcomes over a ten-year period.We conducted a retrospective analysis including all adults (≥ 18 years old starting ART from March 2003-March 2013 in a non-governmental hospital in Phnom Penh, Cambodia. The cumulative incidence of death, lost to follow-up (LTFU, attrition (death or LTFU and first line treatment failure were calculated using Kaplan-Meier methods. Independent risk factors for these outcomes were determined using Cox regression modeling.Over the ten-year period, 3581 patients initiated ART with a median follow-up time of 4.8 years (IQR 2.8-7.2. The median age was 35 years (IQR 30-41, 54% were female. The median CD4 count at ART initiation increased from 22 cells/μL (IQR 4-129 in 2003 to 218 (IQR 57-302 in 2013. Over the 10 year period, a total of 282 (7.9% individuals died and 433 (12.1% were defined LTFU. Program attrition (died or LTFU was 11.1% (95% CI: 10.1%- 12.4% at one year, 16.3% (95% CI: 15.1%-17.6% at three years, 19.8% (95% CI: 18.5%-21.2% at five years and 23.3% (95% CI: 21.6-25.1 at ten years. Male sex and low baseline body mass index (BMI were associated with increased attrition. Factors independently associated with mortality included a low baseline CD4 count, older age, male sex, low baseline BMI and hepatitis B co-infection. Individuals aged above 40 years old had an increased risk of mortality but were less likely to LTFU. There were a total of 137 individuals with first line ART failure starting second line treatment. The probability of first line failure was estimated at 2.8% (95% CI: 2.3%-3.4% at 3 years, 4.6% (95% CI: 3.9%-5.5% at 5 years and 7.8% (95% CI 4.8%-12.5% at ten years of ART. The probability was

    Full Text Available INTRODUCTION: Prevention of acute HIV infections in pregnancy is required to achieve elimination of pediatric HIV. Identification and support for HIV negative pregnant women and their partners, particularly serodiscordant couples, are critical. A mixed method study done in Southern Mozambique estimated HIV incidence during pregnancy, associated risk factors and factors influencing partner's HIV testing. METHODS: Between April 2008 and November 2011, a prospective cohort of 1230 HIV negative pregnant women was followed during pregnancy. A structured questionnaire, HIV testing, and collection of dried blood spots were done at 2-3 scheduled visits. HIV incidence rates were calculated by repeat HIV testing and risk factors assessed by Poisson regression. A qualitative study including 37 individual interviews with men, women, and nurses and 11 focus group discussions (n = 94 with men, women and grandmothers explored motivators and barriers to uptake of male HIV testing. RESULTS: HIV incidence rate was estimated at 4.28/100 women-years (95%CI: 2.33-7.16. Significant risk factors for HIV acquisition were early sexual debut (RR 3.79, 95%CI: 1.04-13.78, p = 0.04 and living in Maputo Province (RR 4.35, 95%CI: 0.97-19.45, p = 0.05. Nineteen percent of women reported that their partner had tested for HIV (93% knew the result with 8/213 indicating an HIV positive partner, 56% said their partner had not tested and 19% did not know their partner test status. Of the 14 seroconversions, only one reported being in a serodiscordant relationship. Fear of discrimination or stigma was reported as a key barrier to male HIV testing, while knowing the importance of getting tested and receiving care was the main motivator. CONCLUSIONS: HIV incidence during pregnancy is high in Southern Mozambique, but knowledge of partners' HIV status remains low. Knowledge of both partners' HIV status is critical for maximal effectiveness of prevention and treatment services to reach

    Bitterness has been suggested to be the main reason for the limited palatability of several vegetables. Vegetable acceptance has been associated with preparation method. However, the taste intensity of a variety of vegetables prepared by different methods has not been studied yet. The objective of this study is to assess the intensity of the five basic tastes and fattiness of ten vegetables commonly consumed in the Netherlands prepared by different methods using the modified Spectrum method. Intensities of sweetness, sourness, bitterness, umami, saltiness and fattiness were assessed for ten vegetables (cauliflower, broccoli, leek, carrot, onion, red bell pepper, French beans, tomato, cucumber and iceberg lettuce) by a panel (n=9) trained in a modified Spectrum method. Each vegetable was assessed prepared by different methods (raw, cooked, mashed and as a cold pressed juice). Spectrum based reference solutions were available with fixed reference points at 13.3mm (R1), 33.3mm (R2) and 66.7mm (R3) for each taste modality on a 100mm line scale. For saltiness, R1 and R3 differed (16.7mm and 56.7mm). Mean intensities of all taste modalities and fattiness for all vegetables were mostly below R1 (13.3mm). Significant differences (p<0.05) within vegetables between preparation methods were found. Sweetness was the most intensive taste, followed by sourness, bitterness, fattiness, umami and saltiness. In conclusion, all ten vegetables prepared by different methods showed low mean intensities of all taste modalities and fattiness. Preparation method affected taste and fattiness intensity and the effect differed by vegetable type. Copyright © 2016 Elsevier Ltd. All rights reserved.

    It is projected that 17 730 women will be diagnosed with breast cancer in Australia in 2017, with 3114 of these predicted to be fatal. Caregiving for a person with cancer can significantly impact caregivers' physical and mental health. Many caregivers feel ill-prepared for this role, especially when care involves complex medical needs accompanied by the psychological challenges experienced following a cancer diagnosis. This study employs a convergent, parallel, mixed methods design combining an online survey with an optional interview. Eligible, consenting participants will be invited to participate in a survey to examine (1) participants' unmet needs, (2) challenges experienced throughout the cancer journey, (3) perceived self-efficacy to determine participants' level of confidence in undertaking caregiver tasks, (4) views regarding suitable content to include in a caregiver training intervention, (5) preferred method of intervention delivery (ie, website, smartphone application and/or interactive video), and (6) preferences for the timing of delivery of the intervention content (ie, ability to choose a module, access to the entire content or have a set order in which they receive the information). Caregivers will be eligible to participate if they (1) are male, (2) have previously cared for or are currently caring for a woman with breast cancer, (3) are aged over 18 years, and (4) do not currently suffer from a cognitive impairment or mental health condition (ie, depression, anxiety). Data analysis will include examination of differences in psychological outcomes and needs based on demographic variables, and mediation analysis to explore whether self-efficacy mediates the relationship between challenges, unmet needs and distress. Qualitative data will be analysed using thematic analysis. The study was reviewed and approved by two human research ethics committees within Australia. We anticipate two to three publications may be developed from the study.

    What today is still experimental will tomorrow be routine. Use of emission tomography, automatic determination of regions of interest, generalisation of Fourrier phase and amplitude analysis, parametric images these will become routine medical protocols. The next ten years will see a saturation in the field of research and a stabilisation in system development. Equipment renewal will be seen from the same angle as in the automotive industry - more for reasons of wear and tear than for reasons of technical advancement

    The observation that the helical TEN2 laser can effectively be simplified by giving up the use of decoupling elements as well as by abolishing the segmentation of the electrode structure is examined. Although, as a consequence of this simplification, the operating pressure range was slightly decreased, the output power could be improved by roughly 30%, a result which is attributed to the new electrode geometry exhibiting lower inductance and lower damping losses.

    In a 1964 decision the National Health and Medical Research Council recommended that radiological examinations of the lower abdomen and pelvis of women of childbearing age should be confined to the 10-day interval following the onset of menstruation. Recent evidence suggests that the first four weeks from the first day of the last menstrual period is not a critically radiosensitive period and consequently strict adherence to the ten-day rule is no longer indicated

    Energy balance, in relation to energy needs in populations of developing countries is an important issue in terms of nutritional status, health and food policy implications. The objective of this study was to measure the variations in discretionary energy expenditure (DEE) in male adult construction workers of different body mass index (BMI), when challenged to heavy work. Twelve adult volunteers engaged in construction work, 18-30 years, BMI range 16.7 to 28.9 were selected from different low income urban sectors in northern Mexico. These individuals were subjected to a specific work load equivalent to a physical activity index (PAI) ≥ 2.1 x BMR, within a time frame of 6 hours a day, eight out of ten days. The rest of the time including one full weekend was to their discretion. Energy expenditure was measured using the 2 H 2 18 O technique. BMR and the thermic effect of food were evaluated by ventilated hood indirect calorimetry. The energy cost of fixed activities was measured by the Oxylog. A daily activity diary was kept throughout the ten days of the protocol. This study shows no evidence that individuals of different energy status in a range of BMI from 16.7 to 28.9 modify the discretionary component of their total daily expenditure to cope with the equivalent of a heavy work load (PAI ≥ 2.1) 11 refs, 1 fig., 3 tabs

    Pupae of Ceratitis capitata (Wiedemann, 1824) were irradiated with 60 Gy gamma radiation and subsequently the emergent males were crossed with females of recessive mutants on white pupa color (w p/w p). A strain with a translocation between autosomal chromosome number 5, carrier of w p+ dominant gene, and Y chromosome was isolated. By this way the T:Y (w p+) 70 strain with sexual dimorphism based on pupal color was obtained. Cytological examination of the males was carried out to confirm the translocation. The genetic stability was monitored under laboratory conditions during 21 generations. The rates of contaminant females emerged from brown pupae were 0,96 to 4,5% and for males from white pupae these rates were 0,26 to 0,66%. These values presented no definite increase tendency. The origin of contaminant genotypes and the potential for utilization of the sterile male techniques are discussed. (author)

    Compared with the well documented neurophysiological findings on negative emotions, much less is known about positive emotions. In the present study, we explored the EEG correlates of ten different positive emotions (joy, gratitude, serenity, interest, hope, pride, amusement, inspiration, awe, and love). A group of 20 participants were invited to watch 30 short film clips with their EEGs simultaneously recorded. Distinct topographical patterns for different positive emotions were found for the correlation coefficients between the subjective ratings on the ten positive emotions per film clip and the corresponding EEG spectral powers in different frequency bands. Based on the similarities of the participants' ratings on the ten positive emotions, these emotions were further clustered into three representative clusters, as 'encouragement' for awe, gratitude, hope, inspiration, pride, 'playfulness' for amusement, joy, interest, and 'harmony' for love, serenity. Using the EEG spectral powers as features, both the binary classification on the higher and lower ratings on these positive emotions and the binary classification between the three positive emotion clusters, achieved accuracies of approximately 80% and above. To our knowledge, our study provides the first piece of evidence on the EEG correlates of different positive emotions.

    Cytogenetic analysis was conducted of 15 lines of the cabbage root fly with hereditary semisterility in the form of late embryonic lethals (LEL). In 14 lines (93%), the presence of translocations was noted. A high yield of translocations linked with the male sex was obtained, which was caused by the fact that determination of male sex in this species is apparently associated with the largest chromosome 6, and not with chromosome 1, as was believed previously

    Low back pain (LBP) is one of the most common disorders affecting office employees working with a computer, which inevitably leads to lower quality of life. The aim of this study was to analyze the quality of life of patients with LBP after application of TENS (Transcutaneous Electrical Nervous Stimulation). The study group included 30 computer workers (26 females and 4 males) aged 30-60 years (45 +/- 12). The quality of life was assessed using the World Health Organization Quality of Life instrument-Abbreviated version (WHOQOL-Bref) before and after 10 applications of TENS. Outcomes were evaluated with a visual analog score (VAS) for pain and Schober's test to measure the ability of a patient to flex his or her lower back. The mean VAS value decreased significantly from 3.83 +/- 1.31 cm at baseline to 3.36 +/- 1.21 cm after treatment. Patients reported pain relief. The highest quality of life scores in terms of social relationships were found in the social category evaluating personal relationships, social support and sexual activity (15.91 +/- 2.07) and mental health (14.32 +/- 1.59). After treatment a significant increase in the flexion of lower back was observed in the majority of patients. No significant correlations between the quality of life and the intensity of pain and the flexion of lower back before and after treatment were found. TENS therapy is an effective technique for pain relief in patients with LBP. TENS can also be used with other methods of LBP treatment and may improve the patients' quality of life.

    cancer population. The initial review identified two RCTs (64 participants) therefore this review now includes a total of three RCTs (88 participants). These studies were heterogenous with respect to study population, sample size, study design, methodological quality, mode of TENS, treatment duration, method of administration and outcome measures used. In one RCT, there were no significant differences between TENS and placebo in women with chronic pain secondary to breast cancer treatment. In the other RCT, there were no significant differences between acupuncture-type TENS and sham in palliative care patients; this study was underpowered. Despite the one additional RCT, the results of this updated systematic review remain inconclusive due to a lack of suitable RCTs. Large multi-centre RCTs are required to assess the value of TENS in the management of cancer-related pain in adults.

    The old saying that open-quotes an ounce of prevention is worth a pound of cureclose quotes rings particularly true in environmental matters in the 1990s. Environmental problems can potentially lead to expensive fines, costly cleanups, negative public relations, and even criminal sanctions against members of the corporation. A recurring pattern of problems has been noted during the performance of environmental disposition, acquisition, and compliance assessments of many different operators in most of the producing states. The ten most common problems found in oilfield audits are discussed here in an effort to enhance the awareness of operators

  6. TENS (transcutaneous electrical nerve stimulation) for labour pain.

    2012-05-01

    Because TENS is applied inconsistently and not always in line with optimal TENS application theory, this may explain why TENS for labour pain appears to be effective in some individuals and not in others. This article reviews TENS theory, advises upon optimal TENS application for labour pain and discusses some of the limitations of TENS research on labour pain. TENS application for labour pain may include TENS applied to either side of the lower spine, set to 200 mus pulse duration and 100 pulses per second. As pain increases, TENS intensity should be increased and as pain decreases, TENS intensity should be reduced to maintain a strong but pain free intensity of stimulation. This application may particularly reduce back pain during labour.

Quantitative analyses consisted of a cross-sectional study in which participants were asked about the likelihood of PrEP uptake by the HIV-negative member of the couple and level of agreement with health care providers offering PrEP to anyone requesting it.We used multivariable regression to examine associations between PrEP questions and covariates of interest and employed an inductive approach to identify key qualitative themes.Among 328 men (164 couples, 62% had heard about PrEP, but approximately one-quarter were mistaking it with post-exposure prophylaxis. The majority of participants had low endorsement of PrEP uptake and 40% were uncertain if health care providers should offer PrEP to anyone requesting it. Qualitative interviews with 32 men suggest that this uncertainty likely stems from concerns regarding increased risk compensation. Likelihood of future PrEP uptake by the HIV-negative member of the couple was positively associated with unprotected insertive anal intercourse but negatively correlated with unprotected receptive anal intercourse.Findings suggest that those at greatest risk may not be receptive of PrEP. Those who engage in moderate risk express more interest in PrEP; however, many voice concerns of increased risk behavior in tandem with PrEP use. Results indicate a need for further education of MSM communities and the need to determine appropriate populations in which PrEP can have the highest impact.

    Interdisciplinary team work is increasingly prevalent, supported by policies and practices that bring care closer to the patient and challenge traditional professional boundaries. To date, there has been a great deal of emphasis on the processes of team work, and in some cases, outcomes. This study draws on two sources of knowledge to identify the attributes of a good interdisciplinary team; a published systematic review of the literature on interdisciplinary team work, and the perceptions of over 253 staff from 11 community rehabilitation and intermediate care teams in the UK. These data sources were merged using qualitative content analysis to arrive at a framework that identifies characteristics and proposes ten competencies that support effective interdisciplinary team work. Ten characteristics underpinning effective interdisciplinary team work were identified: positive leadership and management attributes; communication strategies and structures; personal rewards, training and development; appropriate resources and procedures; appropriate skill mix; supportive team climate; individual characteristics that support interdisciplinary team work; clarity of vision; quality and outcomes of care; and respecting and understanding roles. We propose competency statements that an effective interdisciplinary team functioning at a high level should demonstrate.

    Full Text Available Background: Human cancers comprise a large group of diseases that despite modern methods of diagnosis and advanced treatment techniques its mortality rate is high. Considering the role of environmental and cultural factors in the prevalence of oral cancer, epidemiological studies have a great importance. Objective: The aim of this research was to determine the prevalence of oral squamous cell carcinoma (OSCC in the province of Qazvin in a period of ten years. Methods: In this descriptive - analytical study, the documents of 88 patients with OSCC that were recorded by the Qazvin Cancer Registry Center during 2003-13, were used. Demographic data including age, sex and location of lesions were extracted from patient records. Data analysis were performed using chi-square, t-test and fisher exact test. Findings: Among the 88 patients, the average age was 64.3±17.7. The male to female ratio was 1 to 1.37 and the most involved area was tongue with 39 cases (63.9%, and the lowest was upper lip with 1 case (1.6%. The most of the patients were in the age between 70-80 years old. Conclusions: Pattern of OSCC in this study was similar to the other studies but the number of females and the mean age of patient had increased. Also, the mean age of patients was increased in eight decades and the most involved area tongue was reported.

    Despite significant advances in contraceptive options for women over the last 50 yr, world population continues to grow rapidly. Scientists and activists alike point to the devastating environmental impacts that population pressures have caused, including global warming from the developed world and hunger and disease in less developed areas. Moreover, almost half of all pregnancies are still unwanted or unplanned. Clearly, there is a need for expanded, reversible, contraceptive options. Multicultural surveys demonstrate the willingness of men to participate in contraception and their female partners to trust them to do so. Notwithstanding their paucity of options, male methods including vasectomy and condoms account for almost one third of contraceptive use in the United States and other countries. Recent international clinical research efforts have demonstrated high efficacy rates (90–95%) for hormonally based male contraceptives. Current barriers to expanded use include limited delivery methods and perceived regulatory obstacles, which stymie introduction to the marketplace. However, advances in oral and injectable androgen delivery are cause for optimism that these hurdles may be overcome. Nonhormonal methods, such as compounds that target sperm motility, are attractive in their theoretical promise of specificity for the reproductive tract. Gene and protein array technologies continue to identify potential targets for this approach. Such nonhormonal agents will likely reach clinical trials in the near future. Great strides have been made in understanding male reproductive physiology; the combined efforts of scientists, clinicians, industry and governmental funding agencies could make an effective, reversible, male contraceptive an option for family planning over the next decade.

    To evaluate if hyaluronic acid (HA)-bound spermatozoa surpassed conventional microscopy-selected spermatozoa in the status of sperm DNA integrity by acridine orange (AO) fluorescence staining. Spermatozoa obtained from couples with indication for the intracytoplasmic sperm injection (ICSI) procedure due to male infertility (n = 34) and control males with normal sperm parameters (n = 12) were analyzed using AO fluorescence staining after density-gradient centrifugation (DGC), polyvinylpyrrolidone (PVP)-microscopic selection, and HA-binding selection to determine sperm DNA integrity. Percentages of DNA intact spermatozoa with green fluorescence were significantly higher in both PVP-microscopic selected spermatozoa (82.1 ± 24.0%) and HA-bound spermatozoa (83.9 ± 21.1%) than in spermatozoa prepared by DGC (66.8 ± 24.0%). However, there was no significant difference between the PVP-sperm and HA-sperm groups. When the percentage of green fluorescent spermatozoa prepared by DGC fell initially below 68%, both PVP-microscopic and HA-binding selection failed to select over 90% spermatozoa with intact DNA for ICSI in the male infertility group. Compared to control males with normal sperm parameters (99.3 ± 1.8%), the proportion of green fluorescence sperm after HA-binding selection from couples with male infertility (83.9 ± 21.1%) did not reach the range of > 99% reported by Yagci et al. The percentages of DNA intact spermatozoa between the PVP-sperm and HA-sperm groups were not significantly different. In an ICSI procedure, a well-trained embryologist will have the same ability to choose sperm with intact DNA by conventional microscopic selection as with HA-bound spermatozoa selection.

    Full Text Available A utilização de técnicas não-destrutivas (NDT pode incrementar o nível de informação tecnológica sobre espécies de madeira conhecidas, bem como daquelas ainda não estudadas. A principal vantagem das técnicas NDT é que são rápidas e várias medidas podem ser feitas, melhorando assim o nível de confiança dos resultados. Nesse contexto, o trabalho objetivou avaliar a viabilidade de utilização da técnica de ondas de tensão na estimativa de propriedades de flexão de seis espécies de madeiras amazônicas. As espécies foram escolhidas com base na sua densidade: Balfourodendron riedelianum, Cedrela fissilis, Cordia goeldiana, Bowdichia virgilioides, Dipteryx odorata and Tabebuia sp. Foram obtidas vinte amostras por espécie nas dimensões segundo ASTM D143-94 para a determinação das propriedades de flexão, totalizando assim 120 amostras. Antes do ensaio destrutivo em flexão estática, as amostras foram avaliadas não-destrutivamente por meio da técnica de ondas de tensão para a determinação do módulo de elasticidade dinâmico e a velocidade de propagação das ondas tensão. De acordo com os resultados, os modelos de regressão foram altamente significativos para a predição das propriedades de flexão do conjunto de espécies. Dessa forma, pode-se concluir que o método é adequado para predizer as propriedades de flexão onde há variação, por exemplo, entre espécies. No entanto, quando a variabilidade é baixa, como dentro da espécie, os modelos apresentaram baixa previsibilidade.The utilization of non-destructive testing (NDT can augment the technological information about well-known wood species, as well as those which have not yet been investigated. The main advantage is that NDT methods are fast, and many measures can be undertaken to improve the confidence level of the evaluation. In this context, the paper aims to study the feasibility of the stress wave method to estimate flexural properties of six

In addition, Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum or Ureaplasma parvum were detected by the conventional PCR methods (TMA or real-time PCR) and data from the clone library and conventional PCR methods were compared. Among 58 urine specimens, 38 were successfully analysed using the clone library method. From the specimens, 2427 clones were evaluated and 95 bacterial phylotypes were detected. N. gonorrhoeae was detected from 6 specimens and as the predominant bacterial species in 5 specimens. M. genitalium was detected from 5 specimens and as the predominant bacterial species in 3 specimens. C. trachomatis was detected from 15 specimens using the TMA method, but was detected from only 1 specimen using the clone library method. U. parvum was detected from only 2 specimens using the clone library method. In addition, Haemophilus influenzae and Neisseria meningitidis were also detected in 8 and 1 specimens, respectively. Gardnerella vaginalis, which is a potential pathogen for bacterial vaginitis in women, was detected in 10 specimens. The clone library method can detect the occupancy rate of each bacteria species among the bacterial flora and may be a new method for bacterial analyses in male urethritis.

    The main objective of the Virtual Observatory (VO) is to guarantee an easy and efficient access and analysis of the information hosted in astronomical archives. The Spanish Virtual Observatory (SVO) is a project that was born in 2004 with the goal of promoting and coordinating the VO-related activities at national level. SVO is also the national contact point for the international VO initiatives, in particular the International Virtual Observatory Alliance (IVOA) and the Euro-VO project. The project, led by Centro de Astrobiología (INTA-CSIC), is structured around four major topics: a) VO compliance of astronomical archives, b) VO-science, c) VO- and data mining-tools, and d) Education and outreach. In this paper I will describe the most important results obtained by the Spanish Virtual Observatory in its first ten years of life as well as the future lines of work.

    1983-01-01

    The history, current status, and future plans of the Spacelab program are reviewed, with a focus on the cooperative relationship between ESA and NASA. The initial decision to undertake the program and the three agreements signed to begin its implementation are examined, and the division of responsibilities and financial contributions is discussed insofar as it affected the management structure. Consideration is given to the major facilities, the 50-mission operational cycle, communications, the currently scheduled activities (through 1985), the prospective later uses, and the ten dedicated discipline laboratories. The importance of continuous mutual support during the planning and development phases is stressed. The program so far is considered a success, in terms of the goals set by the participants and in terms of the resolution of the problems inherent in international technological endeavors.

    Amputations involving ten digits are very rare because of different lengths of the digits. A 34-year-old man working in a printing house presented one hour after guillotine amputation involving all ten digits. Surgery was initiated 80 minutes after admission and took seven hours. Under axillary anesthesia, the operation was performed by two teams each consisting of two microsurgeons and two assistants. Replantation was completed without the use of any skin graft or flap. Fingertip examination showed poor arterial circulation in the second, third, and fourth digits of the left hand after 24 hours of replantation and surgical exploration was performed, during which anastomosis of the ulnar digital artery of the second digit was re-established and a Y-shaped vein graft was placed at the level of the third web to restore revascularization of the third and fourth digits. However, these interventions did not prevent the development of necrosis in the distal segment of the fourth digit which resulted in dry gangrene that required amputation. After 38 months of replantation, radiographic examination showed complete union in all fingers without malunion or damage to the joint surface and about 8 degrees of medial angulation in the proximal phalanx of the fourth digit of the right hand. The patient did not have difficulty in performing daily activities and had a considerably good pinching. Losses of active range of motion of the metacarpophalangeal and interphalangeal joints were within the rage of 10 to 30 degrees in both hands. In the assessment of sensation, static and dynamic two-point discrimination test results were 6.1 mm and 4.0 mm, respectively.

    Evaluation of microvascular endothelial function is essential for investigating the pathophysiology and treatment of cardiovascular and metabolic diseases. Although laser speckle contrast imaging technology is well accepted as a noninvasive methodology for assessing microvascular endothelial function, it has never been used to compare male patients with coronary artery disease with male age-matched healthy controls. Thus, the aim of this study was to determine whether laser speckle contrast imaging could be used to detect differences in the systemic microvascular functions of patients with established cardiovascular disease (n=61) and healthy age-matched subjects (n=24). Cutaneous blood flow was assessed in the skin of the forearm using laser speckle contrast imaging coupled with the transdermal iontophoretic delivery of acetylcholine and post-occlusive reactive hyperemia. The maximum increase in skin blood flow induced by acetylcholine was significantly reduced in the cardiovascular disease patients compared with the control subjects (74 vs 116%; P<0.01). With regard to post-occlusive reactive hyperemia-induced vasodilation, the patients also presented reduced responses compared to the controls (0.42±0.15 vs 0.50±0.13 APU/mmHg; P=0.04). In conclusion, laser speckle contrast imaging can identify endothelial and microvascular dysfunctions in male individuals with cardiovascular disease. Thus, this technology appears to be an efficient non-invasive technique for evaluating systemic microvascular and endothelial functions, which could be valuable as a peripheral marker of atherothrombotic diseases in men.

    Full Text Available Background Fulfilling the learners' "real needs" will improve medical education. There are subjects that are necessary for any clinical residents not considering their field of specialty. Among the subjects ten seems to be the most important: research methodology and data analysis, computer-based programs, medical recording, cardiopulmonary and cerebral resuscitation, clinical teaching programs, communication skills, clinical ethics, laboratory examinations, reporting special diseases and death certification, and prescription. Purpose This cross-sectional study assessed educational needs of clinical residents for ten educational subjects. Methods A questionnaire prepared by board faculty members consisted of 10 close-ended questions, and one open­ ended question was distributed among 1307 residents from 22 clinical disciplines, who registered for preboard or promotion exam in June 2000. Results Among the subjects three were the most needed: computer-based programs 149 (60%, data collecting system 606 (49%, and clinical ethics 643 (46%. The prescription standard was the least required 177(13%. Conclusion Complementary training courses on these subjects can be an answer to the clinical residents needs.

    2010-01-01

    Purpose of review Condoms and vasectomy are male controlled family planning methods but suffer from limitations in compliance (condoms) and limited reversibility (vasectomy); thus many couples desire other options. Hormonal male contraceptive methods have undergone extensive clinical trials in healthy men and shown to be efficacious, reversible and appear to be safe. Recent Findings The success rate of male hormonal contraception using injectable testosterone alone is high and comparable to methods for women. Addition of progestins to androgens improved the rate of suppression of spermatogenesis. Supported by government or non-government organizations, current studies aim to find the best combination of testosterone and progestins for effective spermatogenesis suppression and to explore other delivery methods for these hormones. Translation of these advances to widespread use in the developed world will need the manufacturing and marketing skills of the pharmaceutical industry. Availability of male contraceptives to the developing world may require commitments of governmental and non-governmental agencies. In a time when imbalance of basic resources and population needs are obvious, this may prove to be a very wise investment. Summary Male hormonal contraception is efficacious, reversible and safe for the target population of younger men in stable relationships. Suppression of spermatogenesis is achieved with a combination of an androgen and a progestin. Partnership with industry will accelerate the marketing of a male hormonal contraceptive. Research is ongoing on selective androgen and progesterone receptor modulators that suppress spermatogenesis, minimize potential adverse events while retaining the androgenic actions. PMID:20808223

    Purpose: To study the development of Gardner's syndrome by following up 12 subjects in a family for ten years. Methods: 12 subjects with Gardner's syndrome of 4 generations in a family were studied. Six were male and six female. The age of the patients was from 9 to 74 years, with average of 38 years. The examinations consisted of air-barium double contrast radiography of colon, fiber-optic colonoscopy, plain X-ray and body photography. Results: Triology was present in 8 cases (66.7%) and the double signs in 4 cases (33.3%). 4 patients (33.3%) died of malignant degeneration of colonic polyp in 10 years, all occurring in rectum and sigmoid colon, the oldest one was 74 years and the youngest 35 years. Conclusion: The incidence of malignant degeneration of colonic polyp is very high in patients with Gardner's syndrome and may occur in patients older than 30 years, with the peak incidence in the sixth decade. Preventive resection of colonic polyp is still the best treatment

    Full Text Available Aim: Peripheral vascular injuries are usually associated with fatal injuries. Early diagnosis and intervention are so vital for improving a favorable outcome for traumatic vascular injuries. As a preventable cause of death, we aimed to evaluate peripheral vascular injuries in overall deaths in ten year period, 2003-2012. Material and Method: A retrospective evaluation was made of 2845 death cases which had post-mortem examination and autopsy from the 10-year period of 2003-2012 in Eskisehir, Turkey. The mean age of the cases included in the study was 32.5±7.9 years with the highest rate of cases occurring in the 30-39 years age group. Males constituted 89.2% of the victims. The most frequent manner of death was homicide 83.8%.The femoral artery was the most commonly injured vessel 29 cases (78.4%. In this study it was identified that, 33 patients (89.3% died before any medical intervention could be performed. Discussion: Our study shows that, peripheral vascular injuries most commonly caused by sharp objects. The injuries have a low mortality rate when early intervention is made. Autopsies are conducted is very important to explain not only the cause of death but also the treatment process, which would clear the cases of any potential malpractice or negligence claims.

    Full Text Available Dois instrumentos, um deles baseado no princípio da gota pendente e o outro baseado no método da gota girante, para medir a tensão interfacial entre polímeros, são apresentados e comparados aqui. Com ambos instrumentos foi possível visualizar a gota de polímero "on line". Os instrumentos mostraram-se complementares quanto às suas áreas de aplicação. O método da gota pendente deve ser usado quando as quantidades de polímero são limitadas ou quando o polímero mais denso é opaco. O método da gota girante deve ser usado quando a degradação térmica pode ser um problema ou quando o polímero menos denso é opaco.In this paper two apparatuses, one based on the principle of the pendant drop method and one based on the principle of the spinning drop are presented and compared. With both apparatuses it was possible to view the drop in real time and calculate the interfacial tension on-line. The two equipments were shown to be complementary in their use. The pendant drop method should be used when there are limited quantities of polymer and/or the denser polymer is opaque. The spinning drop method should be used when thermal degradation could be a problem and/or when the lighter polymer is opaque.

  11. Ten years for the public Web

    CERN Multimedia

    2003-01-01

    Ten years ago, CERN issued a statement declaring that a little known piece of software called the World Wide Web was in the public domain. Nowadays, the Web is an indispensable part of modern communications. The idea for the Web goes back to March 1989 when CERN Computer scientist Tim Berners-Lee wrote a proposal for a 'Distributed Information Management System' for the high-energy physics community. The Web was originaly conceived and developed to meet the demand for information sharing between scientists working all over the world. There were many obstacles in the 1980s to the effective exchange of information. There was, for example a great variety of computer and network systems, with hardly any common features. The main purpose of the web was to allow scientists to access information from any source in a consistent and simple way. By Christmas 1990, Berners-Lee's idea had become the World Wide Web, with its first server and browser running at CERN. Through 1991, the Web spread to other particle physics ...

    Full Text Available Availability of complete plastid genomes of ten solanaceous species, Atropa belladonna, Capsicum annuum, Datura stramonium, Nicotiana sylvestris, Nicotiana tabacum, Nicotiana tomentosiformis, Nicotiana undulata, Solanum bulbocastanum, Solanum lycopersicum, and Solanum tuberosum provided us with an opportunity to conduct their in silico comparative analysis in depth. The size of complete chloroplast genomes and LSC and SSC regions of three species of Solanum is comparatively smaller than that of any other species studied till date (exception: SSC region of A. belladonna. AT content of coding regions was found to be less than noncoding regions. A duplicate copy of trnH gene in C. annuum and two alternative tRNA genes for proline in D. stramonium were observed for the first time in this analysis. Further, homology search revealed the presence of rps19 pseudogene and infA genes in A. belladonna and D. stramonium, a region identical to rps19 pseudogene in C. annum and orthologues of sprA gene in another six species. Among the eighteen intron-containing genes, 3 genes have two introns and 15 genes have one intron. The longest insertion was found in accD gene in C. annuum. Phylogenetic analysis using concatenated protein coding sequences gave two clades, one for Nicotiana species and another for Solanum, Capsicum, Atropa, and Datura.

  13. Ten steps to a cooler planet

    International Nuclear Information System (INIS)

    2001-01-01

    The overwhelming scientific consensus is that human activities, especially activities that produce greenhouse gases are accumulating in the atmosphere and are changing the intricate balance that has sustained life on earth for millions of years. The estimate is that in Canada about 35 per cent of the greenhouse gases released to the atmosphere come from personal sources. This booklet provides brief account of the ways that individuals contribute to green house gas emissions and provides some helpful hints on how to reduce this personal contribution to the climate change problem. The ten ways suggested are: (1) use public transport as much as possible, (2) buy smaller cars , (3) use the train instead of flying, make fewer long distance trips by combining business and vacation travel, (4) set the thermostat one degree lower and save 525 kg of carbon dioxide per year, (5) avoid overhousing by choosing a smaller house and by making every square foot count, (6) buy energy efficient appliances, (7) reduce water heater's energy consumption by insulating it, (8) reduce meat intake and buy locally produced food in season, (9) minimize garbage production by reusing and recycling, (10) use green power wherever available and contribute to the development of renewable energy sources

    Ekrem Akdeniz

    2016-01-01

    Full Text Available Purpose: Unilateral or bilateral testicular pain lasting more than 3 months is called as chronic orchialgia. Aproximately 25-50% of chronic orchialgia is idiopatic origin. This study aimed the effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS therapy due to Idiopathic Chronic Orchialgia (ICO. Methods: Five patients were included into this study with ICO that diagnosed with physical examination, urine analyses, urinary system x-ray film, and scrotal doppler ultrasound. Medical history revealed that multiple conservative therapy attempts failed to alleviate the pain. Two of the patients had right sided ICO. Traditional TENS device is placed to the most painful points. TENS applied 3 times in a week with duration 30 minutes for 4 weeks. Before and after TENS application, patients were evaluated by using Visual Analog Scale (VAS at first and third months. Results: Median age of patients was 26.20±2.38 (22-30. Mean VAS value was 6.52 ± 0.89 before the procedure. After 1 month VAS value was 3.82 ± 0.83 (p0.05. None of the patients needed any analgesics after during the one month. No complications, hyperemia or hypoesthesia of the scrotal or penile skin, occurred after the procedure. Conclusion: TENS reduces pain by increasing endorphin release in the spinal cord dorsal horn. TENS is very effective method for first 1 month in patients with ICO but its effect reduces by the time. There is no standard therapeutic protocol for idiopathic chronic orchialgia. Therefore TENS may be an alternative for patients who do not benefit from medical therapy and do not want invasive procedures. Short-term use of TENS and low number of the patients are the limitations of this study. Randomized, placebo-controlled, and longer follow-up period studies are needed to better assess the efficacy of TENS for ICO.

    Cardiac catheterization in Qatar was initiated in July 1982. In ten years, a total of 3900 procedures were performed at Hamad General Hospital. Computerized data registry has been maintained since 1982. Isolated coronary angiography was done in 2911 patients; of these, 2635 (90.5%) were men, and 276 (9.5%) were women, the average age of the patients was 47+/-9.2 years (range, twenty-five to eighty-eight). Patients' nationality was Qatari in 492 (17%), and other Arabs in 610 (21%), and 1512 (52%) were from the Asian subcontinent. Myocardial infarction was the most common indication (43%). Single-vessel disease was found in 638 (22%), two-vessel disease in 630 (22%), three-vessel disease in 950 (33%), and nonsignificant coronary artery disease in 693 (24%) patients. Morbidity related to the coronary angiography was reported in 147 (5%) patients, but there was no mortality related to the procedure. In 822 (28%) patients, the age was forty years or younger. The angiographic findings of these younger patients were compared with those of the older ones. Younger patients were usually men of Asian subcontinental origin with a recent myocardial infarction (MI). Often, they had normal coronary arteries or single-vessel disease. Patients of Asian subcontinent origin were usually young male patients with a recent MI, who receive streptokinase, and have single-vessel disease.

    Multiple and inappropriate medications are often the cause for poor health status in the elderly. Medication reviews can improve prescribing. This study aimed to determine if a ten minute medication review by a general practitioner could reduce polypharmacy and inappropriate prescribing in elderly patients. A prospective, randomised study was conducted. Patients over the age of 65 (n = 50) underwent a 10-minute medication review. Inappropriate medications, dosage errors, and discrepancies between prescribed versus actual medication being consumed were recorded. A questionnaire to assess satisfaction was completed following review. The mean number of medications taken by patients was reduced (p < 0.001). A medication was stopped in 35 (70%) patients. Inappropriate medications were detected in 27 (54%) patients and reduced (p < 0.001). Dose errors were detected in 16 (32%). A high level of patient satisfaction was reported. A ten minute medication review reduces polypharmacy, improves prescribing and is associated with high levels of patient satisfaction.

A prospective, randomised study was conducted. Patients over the age of 65 (n = 50) underwent a 10-minute medication review. Inappropriate medications, dosage errors, and discrepancies between prescribed versus actual medication being consumed were recorded. A questionnaire to assess satisfaction was completed following review. The mean number of medications taken by patients was reduced (p < 0.001). A medication was stopped in 35 (70%) patients. Inappropriate medications were detected in 27 (54%) patients and reduced (p < 0.001). Dose errors were detected in 16 (32%). A high level of patient satisfaction was reported. A ten minute medication review reduces polypharmacy, improves prescribing and is associated with high levels of patient satisfaction.

    Catalonia is located in the north-east corner of Spain, on the Mediterranean coast and bordering with France in the north. It is one of the most industrialized and developed regions of Spain, with a per capita income of 10879 ECU per year (1989), 21.9% higher than the Spanish average. It contributes to 20.3% of the Spanish GDP. Primary energy consumption was 16.5 M toe in 1989, covered by the following sources: 3.5% coal, 51.8% oil, 9.4% natural gas, 3.6% hydro, 30.8% nuclear, 0.1% electrical import/export balance and 0.8% waste residuals. Oil dependence is distorted by the existence of a major petrochemical industry that uses more than 2.6 Mtoe of oil derivatives for non-energy purposes. Final energy demand in 1989 was 8.8 Mtoe, 40.9% for industry, 36.9% for transportation and 22.3% for the domestic and services sector. In the 60's, Catalonia's socio-economic development was accompanied by a spectacular increase in the demand for primary energy: from slightly above 2.5 million toe in 1960 to 5.6 Mtoe ten years later. If this decade can be characterized by a steady increase in the total value of consumption, the 70's also constitute years of major changes in the field of energy on an international scale (the oil crisis) and in politics in the Spanish State. 6 refs., 3 figs., 6 tabs

    Kabsch, W; Sander, C; Trifonov, E N

    1982-01-01

    On the assumption that the twist angles between adjacent base-pairs in the DNA molecule are additive a linear system of 40 equations was derived from experimental measurements of the total twist angles for different pieces of DNA of known sequences. This system of equations is found to be statistically consistent providing a solution for all ten possible twist angles of B-DNA by a least squares fitting procedure. Four of the calculated twist angles were not known before. The other six twist angles calculated are very close to the experimentally measured ones. The data used were obtained by the electrophoretic band-shift method, crystallography and nuclease digestion of DNA adsorbed to mica or Ca-phosphate surface. The validity of the principle of additivity of the twist angles implies that the angle between any particular two base-pairs is a function of only these base-pairs, independent of nearest neighbors.

  4. Ten years of the uranium mines at Hamr na Jezere

    International Nuclear Information System (INIS)

    Stehlik, J.

    1976-01-01

    The ten-year long history of the uranium mine at Hamr na Jezere near Ceska Lipa (Czechoslovakia) is briefly discussed. The deposit is of the sedimentary-epigenetic origin and is located in complex hydrogeologic conditions in the so-called Lusatian Cretaceous system in the Bohemian Cretaceous Plateau. The deposit is characteristic of a considerable proportion of zirconium which forms complex minerals with uranium. The ore is exploited using two mining procedures. In areas with favourable geologic and hydrogeologic conditions it is the conventional mining method, in other parts chemical in-situ leaching is employed. The main demands placed on the two mining technologies include the undisturbed Turonian drinking water aquifer, minimum intrusion into the landscape and the treatment of radioactive waters before discharge into public water supplies. The importance of the Hamr deposit and the further development of the Uranium Mines Concern are indicated. (B.S.)

    2014-09-01

    Full Text Available Whole trees from energy thinnings constitute one of many forest fuel sources, yet ten widely applied supply chains could be defined for this feedstock alone. These ten represent only a subset of the real possibilities, as felling method was held constant and only a single market (combustion of whole tree chips was considered. Stages included in-field, roadside landing, terminal, and conversion plant, and biomass states at each of these included loose whole trees, bundled whole trees or chipped material. Assumptions on prices, performances, and conversion rates were based on field trials and published literature in similar boreal forest conditions. The economic outcome was calculated on the basis of production, handling, treatment and storage costs and losses. Outcomes were tested for robustness on a range of object volumes (50–350 m3solid, extraction distances (50–550 m and transport distances (10–70 km using simulation across a set of discrete values. Transport was calculated for both a standard 19.5 m and an extended 24 m timber truck. Results showed that the most expensive chain (roadside bundling, roadside storage, terminal storage and delivery using a 19.5 m timber truck at 158 € td−1 was 23% more costly than the cheapest chain (roadside chipping and direct transport to conversion plant with container truck, at 128 € td−1. Outcomes vary at specific object volumes and transport distances, highlighting the need to verify assumptions, although standard deviations around mean supply costs for each chain were small (6%–9%. Losses at all stages were modelled, with the largest losses (23 € td−1 occurring in the chains including bundles. The study makes all methods and assumptions explicit and can assist the procurement manager in understanding the mechanisms at work.

    2014-02-01

    Although the twentieth century has seen great strides in the development of female contraception, not a single new agent has been introduced as an approved method for common use for male contraception. Condoms (considered uncomfortable by some) and vasectomy (a permanent invasive procedure) are the only options provided to men, leaving an undue burden on women to bear contraceptive responsibility. Significant developments have, however, been made with regard to hormonal and nonhormonal contraception, and minor, reversible, procedural contraception. This article reviews the currently available, soon to be available, and theoretically possible methods of male contraception. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Time-effective protocols may potentially increase people’s compliance with exercise. The purpose of this paper was to compare the relative effects of 16 weeks of high intensity (resistance training (HIT with and without protein supplementation (HIT&P and HVHIT (high volume/high intensity training versus a nontraining control group on cardiometabolic risk factors. One hundred and twenty untrained males 30–50 years old were randomly assigned to 3 subgroups: (a a HIT group; (b a HIT&P group, and (c a waiting-control group (phase I that crossed over to (d high volume/high intensity training (HVHIT during the second study phase. HIT was defined as “single set to failure protocol” while HVHIT consistently applied two sets. Protein supplementation provided an overall intake of 1.5 g/kg/body mass. Primary study endpoint was the metabolic syndrome Z-Score (MetS-Z-Score. MetS-Z-Score significantly improved in all exercise groups (p≤0.001 with no significant difference between HIT, HIT&P, and HVHIT (p≥0.829. However, all the exercise groups differed significantly from the CG (p<0.001 which deteriorated significantly (p=0.039. In conclusion, all exercise protocols were similarly effective in improving cardiometabolic risk factors. Thus, HIT may be the best choice for people with low time budgets looking to improve their cardiometabolic health.

    2003-01-01

    Femoral shaft fractures are a common and temporarily disabling injury in children. Recent advances in orthopedic traumatology have led us at the Hospital Universitario del Valle, in Cali, Colombia, to perform a case series observational study with the use of a more aggressive approach with the new endomedullar titanium nails (TENs) in children suffering femur shaft fractures, in a closed procedure performed under image intensification. The main purpose of this study was to evaluate the outcome of 30 children treated with these nails. Pediatric femoral shaft fractures are more common in males with approximately a 2.75:1 male to female ratio. The age distribution is bimodal, with peaks in the younger than 5 years and mid-teenage groups (10-14 years) because of the increased incidence of high-energy trauma in teenage children (mean age: 9 years). Overall, TENs allowed rapid mobilization with few complications. The results were excellent or satisfactory in our cases. No child lost rotational alignment in the postoperative period. Irritation of the soft tissue near the knee by the nail tip occurred in one patient. As indications, implantation technique, and aftercare are refined, TENs may prove to be the ideal implant to stabilize most pediatric femur shaft fractures, avoiding the prolonged immobilization and complications of traction and spica cast

    How did the universe begin? Where do galaxies come from? How do stars and planets form? Where do the material particles we are made of come from? How did life begin? Today we have only provisional answers to such questions. But scientific progress will improve these answers dramatically over the next ten years, predicts John Gribbin in this riveting book. He focuses on what we know—or think we know—about ten controversial, unanswered issues in the physical sciences and explains how current cutting-edge research may yield solutions in the very near future. With his trademark facility for engaging readers with or without a scientific background, the author explores ideas concerning the creation of the universe, the possibility of other forms of life, and the fate of the expanding cosmos. He examines “theories of everything,” including grand unified theories and string theory, and he discusses the Big Bang theory, the origin of structure and patterns of matter in the galaxies, and dark mass and dark ene...

    Transcutaneous electrical nerve stimulation (TENS) reduces hyperalgesia and pain. Both low frequency (LF) and high frequency (HF) TENS, delivered at the same intensity (90% motor threshold (MT)) daily, result in analgesic tolerance with repeated use by the 5th day of treatment. Thecurrentstudytestedif 1) increasingintensityby 10% per daypreventsthedevelopmentoftolerance to repeated TENS, and 2) iflowerintensity TENS (50 % MT) produces an equivalentreduction in hyperalgesia when compared to 90% MT TENS. Sprague-Dawley rats with unilateral knee joint inflammation (3% carrageenan) were separated according to the intensity of TENS used: Sham, 50% LF, 50% HF, 90% LF, 90% HF, and increased intensity by 10% per day (LF and HF). The reduced mechanical withdrawal threshold following the induction of inflammation was reversed by application of TENS applied at 90% MT and increasing intensity for the first 4 days. On the 5th day, the groups that received 90% MT intensity showed tolerance. Nevertheless, the group that received an increased intensity on each day still showed a reversal of the mechanical withdrawal threshold with TENS. These results show that the development of tolerance can be delayed by increasing intensity of TENS. PMID:22858165

    Full Text Available Objective. To determine male vaccination rates with quadrivalent human papillomavirus vaccine (HPV4 before and after the October 2011 national recommendation to routinely immunize adolescent males. Methods. We reviewed HPV4 dose 1 (HPV4-1 uptake in 292 adolescent males in our urban clinic prior to national recommendations and followed-up for HPV4 series completion rates. After national recommendation, 248 urban clinic and 247 suburban clinic males were reviewed for HPV4-1 uptake. Factors associated with HPV4-1 refusal were determined with multiple logistic regression. Results. Of the initial 292 males, 78% received HPV4-1 and 38% received the 3-dose series. After recommendation, HPV4-1 uptake was 59% and 7% in urban and suburban clinics, respectively. Variables associated with HPV4-1 uptake/refusal included time period, race, type of insurance, and receipt of concurrent vaccines. Conclusions. HPV4-1 vaccination rates in our urban clinic were high before and after routine HPV vaccine recommendations for adolescent males. Our vaccination rates were much higher than in a suburban practice.

    2008-06-01

    Full Text Available Background: Acute lymphoblastic leukemia (ALL is the most common cancer in the pediatric population. With modern treatments, the chance of the complete recovery is nearly 100%. The most important prognostic factors are appropriate treatment protocol and determination of patient risk factors based on clinical, morphological, immunological and cytological characteristics. In this study we reviewed frequency of these factors, like as age, gender, the primary white blood cell number, sub- group on the base of FAB classification, immunophenotype and the clinical progress. Methods: In this retrospective study, we reviewed 877 pediatric patients with the diagnosis of ALL between the years of 1994 and 2004. In these patients the age, gender, primary WBC count, sub-group based on the FAB classification, immunophenotype and the clinical progress in 177 patient with acute lymphoblastic leukemia at Imam Khomeini Hospital between the years of 1994 to 2004 were determined. Results: Of these patients, 1.6% was younger than one year, 24.8% more than ten years old and 73.6% were between the ages of one and ten years; 63.8% were male. WBC counts were above 50,000/ul in 28.8% of the patients. FAB classifications included L1 in 80.2%, L2 in 17.5% and L3 in 2.3% of the patients. Immunophenotypes included pre-B cell in 63.8%, early pre-B cell in 23.1%, T cell in 12.3% and mature B cell in 0.8% of the patients. Marker CD10+ was detected in 88.1% of the B cell cases. In this study group, 74% of the patients recovered, 16.3% died and 16.5% relapsed.Conclusions: The prevalence of FAB-L1 and pre-B cell cases in this study is greater than a previous study, while the prevalence of FAB-L2 and early pre-B cell cases is less than that of the previous study.

    This multicenter study assessed the feasibility of conducting a phase III trial of transcutaneous electrical nerve stimulation (TENS) in patients with cancer bone pain recruited from palliative care services. Eligible patients received active and placebo TENS for 1 hour at site of pain in a randomized crossover design; median interval between applications 3 days. Responses assessed at 30 and 60 minutes included numerical and verbal ratings of pain at rest and on movement, and pain relief. Recruitment, tolerability, adverse events, and effectiveness of blinding were also evaluated. Twenty-four patients were randomised and 19 completed both applications. The intervention was well tolerated. Five patients withdrew: 3 due to deteriorating performance status, and 2 due to increased pain (1 each following active and placebo TENS). Confidence interval estimation around the differences in outcomes between active and placebo TENS suggests that TENS has the potential to decrease pain on movement more than pain on rest. Nine patients did not consider that a placebo was used; the remaining 10 correctly identified placebo TENS. Feasibility studies are important in palliative care prior to undertaking clinical trials. Our findings suggest that further work is required on recruitment strategies and refining the control arm before evaluating TENS in cancer bone pain. Cancer bone pain is common and severe, and partly mediated by hyperexcitability. Animal studies suggest that Transcutaneous Electrical Nerve Stimulation can reduce hyperalgesia. This study examined the feasibility of evaluating TENS in patients with cancer bone pain in order to optimize methods before a phase III trial. Copyright 2010 American Pain Society.

    Low back pain (LBP) affects a large proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an alternative therapy to pharmacological treatments for chronic pain. However, despite its widespread use, the effectiveness of TENS is still controversial. The aim of this systematic review was to determine the efficacy of TENS in the treatment of chronic LBP. We searched MEDLINE, EMBASE, PEDro and the Cochrane Controlled Trials Register up to June 1, 2000. Only randomized controlled clinical trials of TENS for the treatment of patients with a clinical diagnosis of chronic LBP were included. Abstracts were excluded unless further data could be obtained from the authors. Two reviewers independently selected trials and extracted data using predetermined forms. Heterogeneity was tested with Cochran's Q test. A fixed effects model was used throughout for continuous variables, except where heterogeneity existed, in which case, a random effects model was used. Results are presented as weighted mean differences (WMD) with 95% confidence intervals (95% CI), where the difference between the treated and control groups was weighted by the inverse of the variance. Standardized mean differences (SMD) were calculated by dividing the difference between the treated and control by the baseline variance. SMD were used when different scales were used to measure the same concept. Dichotomous outcomes were analyzed with odds ratios. Five trials were included, with 170 subjects randomized to the placebo group receiving sham-TENS and 251 subjects receiving active TENS (153 for conventional mode, 98 for acupuncture-like TENS). The schedule of treatments varied greatly between studies ranging from one treatment/day for two consecutive days, to three treatments/day for four weeks. There were no statistically significant differences between the active TENS group when compared to the placebo TENS group for any outcome measures

    Zeta-function regularization is a powerful method in perturbation theory. This book is meant as a guide for the student of this subject. Everything is explained in detail, in particular the mathematical difficulties and tricky points, and several applications are given to show how the procedure works in practice (e.g. Casimir effect, gravity and string theory, high-temperature phase transition, topological symmetry breaking). The formulas some of which are new can be used for accurate numerical calculations. The book is to be considered as a basic introduction and a collection of exercises for those who want to apply this regularization procedure in practice.

    2010-04-01

    Toxic epidermal necrolysis (TEN) is a rare but life-threatening, allergic drug reaction. Skin blistering with epidermal and mucosal necrolysis with subsequent detachment from an inflamed underlying dermis is a hallmark of the condition. The pathogenesis of TEN is not well understood, accounting for controversies about its management and significant delay in initiating potentially beneficial therapy. There are no management protocols based on a robust evidence base. Prompt recognition of the diagnosis and consensus on early management initiatives are necessary in order to improve outcomes and survival in TEN. To date, TEN management has been directed at arresting the allergic reaction and treating the complications. We have identified a need for specific medical interventions to accelerate wound regeneration. This approach has not previously been adopted in the management of TEN. We observed that in two cases of severe TEN, dramatic re-epithelialization and recovery coincided with the introduction of granulocyte colony-stimulating factor (G-CSF) for neutropenia. We explain how addition of the G-CSF promotes recovery from TEN by enhanced bioregeneration of the damaged tissues through accelerated re-epithelialization. G-CSF has been used for severe neutropenia in TEN, but we recommend and explain why, as in our Chelsea and Westminster protocol, G-CSF should be considered in treating severe TEN irrespective of the severity of neutropenia.

    The Department of Energy created the Human Interference Task Force (HITF) in 1980 to investigate the problems connected with the postclosure, final marking of a filled nuclear waste repository. The task of the HITF is to devise a method of warning future generations not to mine or drill at that site unless they are aware of the consequences of their actions. Since the likelihood of human interference should be minimized for 10,000 years, an effective and long-lasting warning system must be designed. This report is a semiotic analysis of the problem, examining it in terms of the science or theory of messages and symbols. Because of the long period of time involved, the report recommends that a relay system of recoding messages be initiated; that the messages contain a mixture of iconic, indexical, and symbolic elements; and that a high degree of redundancy of messages be employed.

    Elizalde, Emilio

    2012-01-01

    Zeta-function regularization is a powerful method in perturbation theory, and this book is a comprehensive guide for the student of this subject. Everything is explained in detail, in particular the mathematical difficulties and tricky points, and several applications are given to show how the procedure works in practice, for example in the Casimir effect, gravity and string theory, high-temperature phase transition, topological symmetry breaking, and non-commutative spacetime. The formulae, some of which are new, can be directly applied in creating physically meaningful, accurate numerical calculations. The book acts both as a basic introduction and a collection of exercises for those who want to apply this regularization procedure in practice. Thoroughly revised, updated and expanded, this new edition includes novel, explicit formulas on the general quadratic, the Chowla-Selberg series case, an interplay with the Hadamard calculus, and also features a fresh chapter on recent cosmological applications, inclu...

    This study aims to examine the influence of inquiry-based instruction on eighth-grade male and female students' motivation and engagement in science learning in two public junior high schools in central Taiwan. Mixed-methods methodology was adopted with 60 students (32 males and 28 females) in the experimental group and 56 students (28 males and 28 females) in the control group. The study lasted for one semester and six units using inquiry-based teaching (90-180 min each) were implemented in the experimental group. Questionnaires used for measuring students' motivation and engagement in science learning were administered as pre- and post-tests. In addition, eight to ten male and female students from both experimental and control groups, as well as two instructors were interviewed four times throughout the semester. Quantitative data were analyzed with t test and the interview data were fully transcribed and coded. Results show that male and female students under intervention expected to do more experiments because it improved their understanding. Male and female students under intervention also used more learning strategies. However, males benefited more than females from the intervention in regard to their motivation and engagement in learning science. Males improved more in motivational constructs, recognized the value of learning science, and increased their cognitive, behavioral, and emotional engagement because what they learned applied to real life. In contrast, females had higher exam anxiety and lower cognitive engagement due to mathematics fear, stronger sense of pride in class, and caring too much about the right answers.

    2014-01-01

    Summary Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological intervention that activates a complex neuronal network to reduce pain by activating descending inhibitory systems in the central nervous system to reduce hyperalgesia. The evidence for TENS efficacy is conflicting and requires not only description but also critique. Population-specific systemic reviews and meta-analyses are emerging, indicating both HF and LF TENS being shown to provide analgesia, specifically when applied at a strong, nonpainful intensity. The purpose of this article is to provide a critical review of the latest basic science and clinical evidence for TENS. Additional research is necessary to determine if TENS has effects specific to mechanical stimuli and/or beyond reduction of pain and will improve activity levels, function and quality of life.

    Document seasonality occurrence and epidemiologic characteristics of Cyclospora cayetanensis infections during a 10-year period from patients consulting at the University Hospital, Honduras. Retrospective non interventional hospital-based study analyzed laboratory results from the period 2002 to 2011 of fresh and Ziehl-Nielsen carbolfuchsin stained routine stool samples received for parasitologic examination. Sporadically a sample with numerous oocysts was allowed to sporulate in 2.5 % potassium dichromate confirming the presence of bi-cystic bi-zoic oocysts. A total of 35,157 fecal samples were examined during a ten-year span, of which a third (28.4 %) was stained by the Ziehl-Neelsen carbolfuchsin method diagnosing a total of 125 (1.3 %) C.cayetanensis infections. A statistically significant apparent seasonality was observed most years during May to August (range p < 0.036-0.001), with 83.3 % of 125 cases occurring in those rainy months. All C. cayetanensis cases came from urban poor neighborhoods; male/female relation was 1:1 except in 2006, when all patients were females (p = 0.05; r(2) = 22,448). Forty four point eight percent of the stool samples were diarrheic or liquid and 65.6 % infections were identified in children 10 years old or less. Enteric helminths and protozoa co-infected Cyclospora positive patients in 52 instances.: 8 % Ascaris lumbricoides, 8 % Giardia duodenalis, 23.2 % Blastocystis spp. and less frequently Entamoeba histolytica/E. dispar, Strongyloides stercoralis, and Trichuris trichiura. Results suggest a seasonal pattern for Cyclospora infections diagnosed in a clinical setting during the rainy months in Tegucigalpa and surrounding areas. Community studies should be conducted to support or dispute these observations.

    To assess the immediate effect of conventional and burst transcutaneous electrical nerve stimulation (TENS) in combination with cryotherapy on pain threshold and tolerance in healthy individuals. Randomised, controlled trial. University laboratory. One hundred and twelve healthy women. Volunteers were allocated at random to seven groups (n=16): (1) control, (2) placebo TENS, (3) conventional TENS, (4) burst TENS, (5) cryotherapy, (6) cryotherapy in combination with burst TENS, and (7) cryotherapy in combination with conventional TENS. Pain threshold and tolerance were measured by applying a pressure algometer at the lateral epicondyle of the humerus, before and after each intervention. The primary outcome measure was pressure pain threshold. A significant increase in pain threshold and tolerance at the 5% level of significance was recorded as follows: burst TENS {pain threshold: mean difference 1.3 [95% confidence interval (CI) 1.4 to 1.2]; pain tolerance: mean difference 3.8 (95% CI 3.9 to 3.7)}, cryotherapy [pain threshold: mean difference 1.3 (95% CI 1.4 to 1.2); pain tolerance: mean difference 1.9 (95% CI 1.8 to 2.0)] and cryotherapy in combination with burst TENS [pain threshold: mean difference 2.6 (95% CI 2.4 to 2.8); pain tolerance: mean difference 4.9 (95% CI 5.0 to 4.8)]. Cryotherapy in combination with burst TENS provided greater analgesia compared with the other groups (Pcryotherapy in combination with burst TENS to reduce induced pain, and suggest a potentiating effect when these techniques are combined.

    2017-12-01

    First coined by Howe in 2006, the field of crowdsourcing has grown exponentially. Despite its growth and its transcendence across many fields, the definition of crowdsourcing has still not been agreed upon, and examples are poorly indexed in peer-reviewed literature. Many examples of crowdsourcing have not been scaled-up past the pilot phase. In spite of this, crowdsourcing has great potential, especially in global health where resources are lacking. This narrative review seeks to review both indexed and grey crowdsourcing literature broadly in order to explore the current state of the field. This is a review of reviews of crowdsourcing. Semantic searches were conducted using Google Scholar rather than indexed databases due to poor indexing of the topic. 996 articles were retrieved, of which 69 were initially identified as being reviews or theoretically-based. 21 of these were found to be irrelevant and 48 articles were reviewed. This narrative review focuses on defining crowdsourcing, taxonomies of crowdsourcing, who constitutes the crowd, research that is amenable to crowdsourcing, regulatory and ethical aspects of crowdsourcing and some notable examples of crowdsourcing. Crowdsourcing has the potential to be hugely promising, especially in global health, due to its ability to collect information rapidly, inexpensively and accurately. Rigorous ethical and regulatory controls are needed to ensure data are collected and analysed appropriately and crowdsourcing should be considered complementary to traditional research methods.

  18. Laryngeal chondrosarcoma - Ten years of experience

    Directory of Open Access Journals (Sweden)

    José Fernando dos Santos Oliveira

    2014-07-01

    Full Text Available INTRODUCTION: Laryngeal involvement by cartilaginous tumors is rare. However, although accounting for only 1% of laryngeal tumor pathology, they are the most frequently occurring non-epithelial neoplasms. The most probable location is the endolaryngeal surface of the cricoid cartilage. Their symptoms are variable, depending on the size and location, and may include hoarseness, stridor, and dyspnea. Treatment is based on surgical excision. Some centers take into account the degree of differentiation and whether it is a case of relapse when deciding to perform a radical resection. AIM: To evaluate this disease in a sample of the Portuguese population. METHODS: A review of the medical records from 2002 to 2012 by assessment of clinical processes was performed. Data on demographics, clinical treatments, and outcomes were collected. RESULTS: Six patients were included in the study. Five of them underwent total laryngectomy, and in one case, partial excision of the thyroid cartilage was performed. None of the patients had either metastases or tumor-related death. CONCLUSION: Laryngeal chondrosarcomas remain a rare disease of unknown etiology, with slow and insidious symptoms. The treatment is surgical, with favorable prognosis, and metastases rarely occur. The main concern regards their propensity to relapse.

    To review the progress made over the past decade with regard to the treatment of enuresis and encopresis, as well as advances in the understanding of etiological mechanisms. Separate computerized literature (English language only) searches of Medline and PsycINFO databases were conducted under the parameter of enuresis and children-adolescents, as well as encopresis and children-adolescents. There has been a substantial decrease in published research concerning the use of imipramine to treat enuresis compared with the prior two decades, accompanied by a corresponding increase in the number of papers concerning desmopressin acetate (DDAVP), which has become the primary pharmacological treatment. Genetic studies of large pedigrees have further confirmed the importance of heritable factors. With regard to encopresis, the research has focused primarily on pathophysiological factors related to the colon and anal sphincter. The widespread use of DDAVP has been the primary addition to treatment strategies over the past decade. The bell-and-pad method of conditioning, the only major treatment that has enduring benefit after being withdrawn, is the most cost-effective and appears to be underutilized. Research into etiological mechanisms has focused primarily on the mechanism of action of DDAVP and advances in the understanding of genetic factors. Advances in the treatment and etiological understanding of encopresis have been less impressive.

    2016-05-01

    Nearly half of all pregnancies worldwide are unplanned, despite numerous contraceptive options available. No new contraceptive method has been developed for men since the invention of condom. Nevertheless, more than 25% of contraception worldwide relies on male methods. Therefore, novel effective methods of male contraception are of interest. Herein we review the physiologic basis for both male hormonal and nonhormonal methods of contraception. We review the history of male hormonal contraception development, current hormonal agents in development, as well as the potential risks and benefits of male hormonal contraception options for men. Nonhormonal methods reviewed will include both pharmacological and mechanical approaches in development, with specific focus on methods which inhibit the testicular retinoic acid synthesis and action. Multiple hormonal and nonhormonal methods of male contraception are in the drug development pathway, with the hope that a reversible, reliable, safe method of male contraception will be available to couples in the not too distant future.

    Skull-photo superimposition is a technique used to identify the relationship between the skull and a photograph of a target person: and facial reconstruction reproduces antemortem facial features from an unknown human skull, or identifies the facial features of unknown human skeletal remains. These techniques are based on soft tissue thickness and the relationships between soft tissue and the skull, i.e., the position of the ear and external acoustic meatus, pupil and orbit, nose and nasal aperture, and lips and teeth. However, the ear and nose region are relatively difficult to identify because of their structure, as the soft tissues of these regions are lined with cartilage. We attempted to establish a more accurate method to determine the position of the nasal tip from the skull. We measured the height of the maxilla and mid-lower facial region in 55 Japanese men and generated a regression equation from the collected data. We obtained a result that was 2.0±0.99mm (mean±SD) distant from the true nasal tip, when applied to a validation set consisting of another 12 Japanese men.

    Fibromyalgia is characterized by a range of symptoms that include muscle pain, fatigue and sleep disorders. Transcutaneous electrical nerve stimulation (TENS) is an established method for pain relief. The purpose of the study was to evaluate the effectiveness and safety of the use of two simultaneously new TENS devices for fibromyalgia pain. After Ethics approval and informed consent, 39 patients were prospectively divided into three groups to evaluate TENS device, applied simultaneously in each patient: (1) at the lower back (perpendicular to the vertebrae canal, at the level of the 5th lumbar vertebrae) and (2) centrally above and below the space between the C7 and T1 spinous processes. The devices were applied for 20 min at 12-h interval during 7 consecutive days. For the placebo group (PG), the devices did not transmitted electrical stimulus. The single-TENS group (STG) (n = 13) had one active and one placebo TENS. The DTG applied both active TENS devices at the low back and cervical areas. Diclofenac was used as rescue analgesic. The efficacy measures were pain relief, reduction in use of daily analgesic tablets, quality of sleep and fatigue. The evaluation within groups revealed that patients from DPG refereed no pain relief when compared to their previous VAS pain score (8 cm, p > 0.05), while patients from the STG refereed improvement of 2.5 cm in the pain VAS (previous 8.5 cm compared to 6 cm after treatment) (p pain (previous 8.5-4.3 cm) (p STG > PG (p TENS improved pain relief in fibromyalgia pain, pain and fatigue were further improved when two active devices were simultaneously applied at the low back and cervical area, with no side effects.

    Full Text Available Introduction Cephalgia or cephalalgia is one of the most common symptoms in the general population. Objective To compare the efficacy of physical therapy modalities, through manual therapy and the effect of Transcutaneous Nerve Stimulation (TENS for tension-type cephalalgia. Materials and methods The study was compounded by 60 subjects, but only 40 of them completed it, due to the exclusion criteria. These were divided into control group and intervention group. The control group received treatment — manual therapy. The intervention group received TENS Burst. Patients underwent ten sessions of treatment, made at every two days on a week, lasting 30 minutes each session. Results The characteristics related to lifestyle, postural issues and range of motion are responsible for the main causes of tension-type cephalalgia. Discussion treatments showed effective results in all cases in relation to pain intensity, but the use of manual therapy techniques give the patient a better quality of life compared to the use of TENS. Final considerations The treatment of this condition deserves analysis and studies; however, there are only a few studying physical therapy techniques, especially regarding to the use of TENS.

    In 2008, 400 males ≥18 years old who paid or traded for sex with a female sex worker (FSW) in Tijuana, Mexico, in the past 4 months completed surveys and HIV/STI testing; 30 also completed qualitative interviews. To analyze environmental sources of HIV vulnerability among male clients of FSWs in Tijuana, we used mixed methods to investigate correlates of clients who met FSWs in nightlife venues and clients' perspectives on venue-based HIV risk. Logistic regression identified micro-level correlates of meeting FSWs in nightlife venues, which were triangulated with clients' narratives regarding macro-level influences. In a multivariate model, offering increased pay for unprotected sex and binge drinking were micro-level factors that were independently associated with meeting FSWs in nightlife venues versus other places. In qualitative interviews, clients characterized nightlife venues as high risk due to the following macro-level features: social norms dictating heavy alcohol consumption; economic exploitation by establishment owners; and poor enforcement of sex work regulations in nightlife venues. Structural interventions in nightlife venues are needed to address venue-based risks. Copyright © 2011 Elsevier Ltd. All rights reserved.

  14. Male depression in females?

    2010-02-01

    Scientific evidence for a male-typed depression ("male depression") is still limited, but mainly supports this concept with respect to single externalizing symptoms or symptom clusters. In particular, studies on non-clinical populations including males and females are lacking. The present study aims at assessing general well-being, the risk and the symptoms of male depression dependent on biological sex and gender-role orientation on instrumental (masculine) and expressive (feminine) personality traits in an unselected community sample of males and females. Students (518 males, 500 females) of the Ludwig-Maximilians-University of Munich, Germany, were asked to participate in a "stress study" and complete the following self-report questionnaires: the WHO-5 Well-being Index [Bech, P., 1998. Quality of Life in the Psychiatric Patient. Mosby-Wolfe, London], the Gotland Scale for Male Depression [Walinder, J., Rutz, W., 2001. Male depression and suicide. International Clinical Psychopharmacology 16 (suppl 2), 21-24] and the German Extended Personal Attribute Questionnaire [Runge, T.E., Frey, D., Gollwitzer, P.M., et al., 1981. Masculine (instrumental) and feminine (expressive) traits. A comparison between students in the United States and West Germany. Journal of Cross-Cultural Psychology 12, 142-162]. General well-being of the students was significantly lower compared to population norms. Contrary to expectations, female students had a greater risk of male depression than male students (28.9% vs. 22.4%; p<0.05). Overall, prototypic depressive symptoms as well as externalizing symptoms were more pronounced in females. In the subgroup of those at risk for male depression, biological sex and kind of symptoms were unrelated. Principal component analyses revealed a similar symptom structure for males and females. Low scores on masculinity/instrumentality significantly predicted higher risk of male depression, independent of biological sex. The study sample is not

    2001-03-01

    Based on the experiences of the Gotland Study that education of general practitioners about depressive illness resulted in a statistically significant reduction in the number of female suicides, leaving the rate of male suicides almost unaffected, we propose the concept of a male depressive syndrome. This syndrome comprises a low stress tolerance, an acting-out behavior, a low impulse control, substance abuse and a hereditary loading of depressive illness, alcoholism and suicide. This notion is supported by data from The Amish study as well as the concept of van Praag of a stress-precipitated, cortisol-induced, serotonin-related and anxiety-driven depressive illness most often seen in males. In order to identify depressed males, the Gotland Male Depression Scale has been developed. Some preliminary data using the scale in a group of alcohol-dependant patients are presented.

  16. [Male contraception and its perspectives].

    Science.gov (United States)

    Belaisch, J

    1982-11-01

    Doctors specializing in male contraception are aware of the very real difficulties hindering the development of an effective method in this field. Others believe that the reason this type of contraception is lagging behind is male chauvinism or a certain fear that men have of losing their virility along with their fertilizing capacity. Since available methods of contraception (condom, vasectomy) have low levels of acceptability and reversibility, research has proceeded along other avenues. 1) Gossypol reduces the number and motility of spermatozoa but its general side effects are not exceptional. 2) Restraining hormonal action (progrestogens, LH-RH agonists) also reduce testicular function and for this reason, require simultaneous administration of androgens. Thus far this has not been resolved; azoospermia is not obtained in every case and when it is, it does not necessarily last. 3) A method involving the epididymis, with a view to preventing spermatozoa from acquiring their normal motility and fertilizing capacity by affecting protein and enzyme synthesis, is also being studied. Perhaps, as has been suggested by the Bicetre Hospital research team, we should be content with methods applicable to certain categories of men. Male contraception would then develop step by step rather than by huge bounds as female contraception. full text

    Full Text Available Objective: To examine the potential effects of lifestyle factors on male reproductive health. Evidence of a global decline in human sperm quality over recent decades has been accumulating. Environmental, occupational, and modifiable lifestyle factors may contribute to this decline. This review focuses on key lifestyle factors that are associated with male infertility such as smoking cigarettes, alcohol intake, use of illicit drugs, obesity, psychological stress, advanced paternal age, dietary practices, and coffee consumption. Other factors such as testicular heat stress, intense cycling training, lack of sleep and exposure to electromagnetic radiation from mobile phone use are briefly discussed. Materials and method: A comprehensive literature search was performed to identify and synthesise all relevant information, mainly from within the last decade, on the major lifestyle factors associated with male infertility and semen quality. Database searches were limited to reports published in English only. A manual search of bibliographies of the reports retrieved was conducted to identify additional relevant articles. Results: In all, 1012 articles were identified from the database search and after reviewing the titles and abstract of the reports, 104 articles met the inclusion criteria. Of these, 30 reports were excluded as the full-text could not be retrieved and the abstract did not have relevant data. The remaining 74 reports were reviewed for data on association between a particular lifestyle factor and male infertility and were included in the present review. Conclusion: The major lifestyle factors discussed in the present review are amongst the multiple potential risk factors that could impair male fertility. However, their negative impact may well be mostly overcome by behaviour modification and better lifestyle choices. Greater awareness and recognition of the possible impact of these lifestyle factors are important amongst couples seeking

  4. Benign papilloma of the male breast following chronic phenothiazine therapy.

    Sara, A S; Gottfried, M R

    1987-05-01

    Benign intraductal papilloma is a rare lesion in the male breast. The authors report the occurrence of an intraductal papilloma in a male with more than a ten-year history of phenothiazine therapy (Mellaril and Prolixin). Phenothiazines have been demonstrated to cause elevated serum prolactin levels. The literature regarding the relationship between prolactin and mammary tumors in rodents and in humans remains controversial. The occurrence of this rare male breast tumor in the setting of chronic phenothiazine therapy raises further questions as to the role of prolactin in the development of mammary tumors.

    Motivation has long been associated with sports engagement. However, to date no research has been performed to understand the domain of motivation among ten-pin bowlers. The purpose of this study was to investigate different types of motivation (i.e., intrinsic vs. extrinsic) based on self-determination theory from the perspective of gender and the bowler type (competitive vs. casual). A total of 240 bowlers (104 male, 136 female; 152 competitive, 88 casual) with a mean age of 16.61 ± 0.78 years were recruited in Kuala Lumpur. The Sport Motivation Scale, a 28-item self-report questionnaire measuring seven subscales (i.e., intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, extrinsic motivation to identify regulation, extrinsic motivation for introjection regulation, extrinsic motivation to external regulation, and amotivation) was administered. Results showed significant differences (t=10.43, df=239, p=0.01) between total scores of intrinsic and extrinsic motivation among ten-pin bowlers. There were significant gender differences with respect to intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, and extrinsic motivation to identify regulation. However, no significant bowler type differences were found for either the intrinsic (t=-1.15, df=238, p=0.25) or extrinsic (t=-0.51, df=238, p=0.61) motivation dimensions. In conclusion, our study demonstrated substantial intrinsic motivation for gender effects, but no bowler type effects among adolescent ten-pin bowlers.

    Chronic low-back pain (LBP) affects a significant proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an adjunct to the pharmacological management of pain. However, despite its widespread use, the usefulness of TENS in chronic LBP is still controversial. The aim of this systematic review was to determine the effectiveness of TENS in the management of chronic LBP. We searched the Cochrane Central Register of Controlled Trials (Issue 2, 2005), MEDLINE, EMBASE and PEDro up to April 1, 2005. Only randomized controlled clinical trials (RCTs) evaluating the effect of TENS on chronic LBP were included. Abstracts were excluded unless further data could be obtained from the authors. Two reviewers independently selected trials and extracted data using predetermined forms. Heterogeneity was tested with Cochrane's Q test. A fixed effect model was used throughout for calculating continuous variables, except where heterogeneity existed, in which case, a random effects model was used. Results are presented as weighted mean differences (WMD) with 95% confidence intervals (95% CI), where the difference between the treated and control groups was weighted by the inverse of the variance. Standardized mean differences (SMD) were calculated by dividing the difference between the treated and control by the baseline variance. SMD were used when different scales were used to measure the same concept. Dichotomous outcomes were analyzed with odds ratios. The only two RCTs (175 patients) meeting eligibility criteria differed in study design, methodological quality, inclusion and exclusion criteria, type and method of TENS application, treatment schedule, co-interventions and final outcomes. In one RCT, TENS produced significantly greater pain relief than the placebo control. However, in the other RCT, no statistically significant differences between treatment and control groups were shown for multiple outcome measures. Pre

  7. Male Body Practices.

    2017-03-01

    The pressure on boys and men to engage in extensive body practices (e.g., closely monitored eating and exercise habits) and achieve ideal male bodies has grown significantly over the past 20 years. Central to the depiction of ideal male bodies and body practices are both the pursuit and achievement of lean and well-defined muscles. The labels "pitches," "purchases," and "performativities" were inductively derived from the literature, and used to describe the multifaceted connections between masculinities, muscularity, and idealized male body practices. "Pitches" distil how popular culture posture norms of masculinity, and manly bodies and behaviors attainable and necessary. "Purchases" refer to men's diverse buy-in to dominant discourses about acceptable male bodies and practices. "Performativities" chronicle how men embody and navigate gender norms as they evaluate their own bodies, behaviors, and eating habits and those of their peers. Based on findings from the current scoping review, future research could benefit from fully linking masculinities with the drive for muscularity to address health and social risks associated with the pursuit of the idealized male body. In highlighting the plurality of masculinities and the complexity of men's diverse identities, health care providers can better reach and support men. Focusing on, and celebrating, a wider range of male bodies could help recenter dominant discourses about how and whose bodies and experiences are idealized. The current scoping review article offers an overview of how masculinities and muscularity have been linked to male body practices, and recommendations to advance this emergent field.

    Ten percent of all homicide perpetrators are female and homicidal acts committed by women are mostly a result of interpersonal conflicts. We carried out a retrospective psychosocial analysis of ten homicide cases committed by women with an urban mid-European background. We evaluated characteristic determinants regarding 1) deed circumstances and motives, 2) the perpetrators, and 3) the victims. Results were compared with the literature on female and male homicides. Autopsy records of the Institute of Legal Medicine of the University Hospital of Düsseldorf, Germany, during the time period from 2006 to 2011 were searched for homicides committed by female perpetrators. Prosecution files were reviewed for further information. The sample comprised N = 10 female homicide perpetrators and eleven victims. The mentioned determinants of the homicide were fairly consistent. All deeds occurred in the domestic context; they were mostly unplanned. All perpetrators were socially isolated and faced socially challenging situations. Most perpetrators were of low socioeconomic status. Furthermore, all victims were helpless and/or dependent on the perpetrator. The presence of a major psychiatric disorder was uncommon and, in contrast to male perpetrators, most women had no previous convictions. The potential value of these core findings in our sample regarding prevention is discussed. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    Chotirmall, S H

    2011-04-05

    Infertility rates among males with cystic fibrosis (CF) approximate 97%. No information is currently available within Ireland determining an understanding of fertility issues and the best methods of information provision to this specialized group. This study aimed to determine understanding and preferred approaches to information provision on fertility issues to Irish CF males. A Descriptive Study utilizing prospective coded questionnaires was mailed to a male CF cohort (n=50). Sections included demographics, fertility knowledge & investigation. Response rate was 16\\/50 (32%). All were aware that CF affected their fertility. More than two-thirds (n=11) were able to provide explanations whilst only one-third (n=5) provided the correct explanation. Significant numbers stated thoughts of marriage and a future family. Half have discussed fertility with a healthcare professional (HCP). Mean age of discussion was 21.9 years. One third preferred an earlier discussion. The commonest first source for information was written material which was also the preferred source. Three-quarters requested further information preferring again, written material. Significant gaps in sex education of Irish CF males exist. Discussion should be initiated by HCPs and centre-directed written material devised to address deficiencies.

    Full Text Available Background: There is scarcity of data of the epidemiology of leukaemia in Arab countries including Yemen. Understanding patterns of leukaemia underpins epidemiology and can provide insight into disease etiology. The aim of this research is to determine the epidemiologic pattern of adult leukaemia in Yemen. Methods: The research is a descriptive cross-sectional study. We analyzed the data of 702 adult patients with leukaemia, who were newly diagnosed over a ten-year period between October 1999 and October 2009 at the referral haematology centre in Sana’a at Al-Jomhori Teaching Hospital, according to type of leukaemia, age, sex, geographic distribution and time of diagnosis. Results: Acute Myeloid Leukaemia (AML was found to be the most common (45.1% followed by Chronic Myeloid Leukaemia (CML (26.5%, Acute Lymphoid Leukaemia (ALL (17.7% and Chronic Lymphoid Leukaemia (CLL (10.7%, respectively. There was an almost equal prevalence of AML and CML for males and females but males had significantly more cases of ALL and CLL (p =0.008. A significant variation in geographic pattern showed that the highest number of cases is seen the Central mountainous region and the least number of cases in the South-eastern region which is coastal and lowland (p<0.001. The seasonal variation showed that higher number of ALL cases was seen in the summer months (33% compared with other seasons (21% in the spring, 24.2% in autumn and 21.8% in winter. Conclusions: The pattern of adult leukaemia in Yemen is different from that seen in western countries which could be attributed to different environmental exposure. The geographic pattern indicates a possible role of certain environmental factors which warrant further investigations. The pattern of seasonal variation needs further studies for evaluating the seasonality.

    Full Text Available Infertility by definition, is not to get pregnant within one year of regular sexual relationship without protection, affects 15-20% of reproductive age couples. Approximately 30% of infertility cases are male originated. Male infertility is caused by endocrine-related genetic defects affecting urogenital system function. These defects adversely affect subsequent spermatogenesis, sexual function, fertility, early embryonic stage of sexual maturation. Autosomal and gonosomal, numerical and structural chromosome abnormalities and related syndromes rank at the top causes of male infertility. Similar chromosome abnormalities are detected in male infertility and as the rate of these abnormalities increase, it was found to reduce sperm count especially in azospermic and oligozoospermic men.

    Full Text Available Male reproduction is governed by the classical hypothalamo-hypophyseal testicular axis: Hypothalamic gonadotropin releasing hormone (GnRH, pituitary luteinizing hormone (LH and follicle stimulating hormone (FSH and the gonadal steroid, principally, testosterone. Thyroid hormones have been shown to exert a modulatory influence on this axis and consequently the sexual and spermatogenic function of man. This review will examine the modulatory influence of thyroid hormones on male reproduction.

  15. Supersymmetric gauged scale covariance in ten and lower dimensions

    2004-01-01

    We present globally supersymmetric models of gauged scale covariance in ten, six, and four dimensions. This is an application of a recent similar gauging in three dimensions for a massive self-dual vector multiplet. In ten dimensions, we couple a single vector multiplet to another vector multiplet, where the latter gauges the scale covariance of the former. Due to scale covariance, the system does not have a Lagrangian formulation, but has only a set of field equations, like Type IIB supergravity in ten dimensions. As by-products, we construct similar models in six dimensions with N=(2,0) supersymmetry, and four dimensions with N=1 supersymmetry. We finally get a similar model with N=4 supersymmetry in four dimensions with consistent interactions that have never been known before. We expect a series of descendant theories in dimensions lower than ten by dimensional reductions. This result also indicates that similar mechanisms will work for other vector and scalar multiplets in space-time lower than ten dimensions

    Full Text Available Abstract Background The development of alternative approaches in ectoparasite management is currently required. Essential oils have been demonstrated to exhibit fumigant and topical toxicity to a number of arthropods. The aim of the present study was to assess the potential efficacy of ten essential oils against Sarcoptes scabiei. Methods The major chemical components of the oils were identified by GC-MS analysis. Contact and fumigation bioassays were performed on Sarcoptes mites collected from experimentally infected pigs. For contact bioassays, essential oils were diluted with paraffin to get concentrations at 10, 5, and even 1% for the most efficient ones. The mites were inspected under a stereomicroscope 10, 20, 30, 40, 50, 60, 90, 120, 150, and 180min after contact. For fumigation bioassay, a filter paper was treated with 100 μL of the pure essential oil. The mites were inspected under a stereomicroscope for the first 5min, and then every 5min until 1h. Results Using contact bioassays, 1% clove and palmarosa oil killed all the mites within 20 and 50min, respectively. The oils efficacy order was: clove > palmarosa > geranium > tea tree > lavender > manuka > bitter orange > eucalyptus > Japanese cedar. In fumigation bioassays, the efficacy order was: tea tree > clove > eucalyptus > lavender > palmarosa > geranium > Japanese cedar > bitter orange > manuka. In both bioassays, cade oil showed no activity. Conclusion Essential oils, especially tea tree, clove, palmarosa, and eucalyptus oils, are potential complementary or alternative products to treat S. scabiei infections in humans or animals, as well as to control the mites in the environment.

  1. Genetically conditioned male sterility

    International Nuclear Information System (INIS)

    Gottschalk, W.

    1976-01-01

    A survey is given of two different types of genetically controlled male sterility in higher plants. 'Functional' male sterility is due to the action of mutated genes causing a misdifferentiation of the growing points in different specific ways. Under the influence of the genes of this group either the stamens or the archespore tissues are not differentiated. In other mutants functionable male germ cells are produced but cannot be used for fertilizing the egg cells because the anthers remain closed or anthers and stigma become spatially separated from each other. Other genes of the group are responsible for the transformation of stamens into carpels, i.e. for a change of the hermaphrodite flower into a unisexually female one. A second type of male sterility is due to the action of ms genes influencing the course of micro-sporogenesis directly. They cause the breakdown of this process in a specific meiotic stage characteristic for each gene of the group. This breakdown is introduced by the degeneration of PMCs, microspores, or pollen grains preventing the production of male germ cells. The female sex organs remain uninfluenced. (author)

  2. Male sterility in chestnuts

    Omura, Mitsuo; Akihama, Tomoya

    1982-01-01

    A tentative plan was proposed for chestnuts based on their pollination system, male sterility and restoration. The studies on the male sterility of 1,063 cultivars and clones suggested that there were three types of male sterility. The first type (S-1) was characterized by antherless florets. In the second type (S-2), the catkins fell before anthesis, and the third type (S-3) appeared to develop normally in gross floral morphology, but the pollen grains were abnormal in shape and did not have germinating power. In an interspecific hybrid clone CS which belonged to S-1, fertility was restored in an open pollinated progeny. The use of CS and CSO-3 with its restored fertility, permitted the planning of breeding the chestnut hybrid cultivars propagated by seeds. The inbred clones with either male sterility or restorer genes are first bred mainly by back crossing with parents with favorable pollen. The clones are selected individually for early bearing, wasp and disease resistance, and restoration. Then, the hybrid seedling lines between male sterile and restorer inbreds are evaluated for homogenity in nut characters and tree habits. Next, the hybrid seedling lines selected will be examined for crop yield, vigor and cross compatibility. The superior seedling lines are finally selected, and the parental inbreds are grafted to be propagated for seed production orchards. (Kaihara, S.)

    Full Text Available Compared to periodic crystals, quasicrystals have higher point group symmetry and are more favorable in achieving complete band-gaps. In this report, a top-cut prism interferometer is designed to fabricate ten-fold photonic quasicrystalline structures. By optimizing the exposing conditions and material characteristics, appropriate quasicrystals have been obtained in the SU8 photoresist films. Atomic Force Microscopy and laser diffraction are used to characterize the fabricated structures. The measurement results show the consistence between the theoretical design and experiments. This will provide guidance for the large-area and fast production of ten-fold quasicrystalline structures with high quality.

    The ten day rule recommends that non-urgent diagnostic radiography of the abdomen in women of child-bearing capacity should be confined to the pre-ovulatory phase of the menstrual cycle. Arguments for and against this rule are reviewed. The attitudes and organization of radiographic practice in the UK differ from those in the USA. Assessment of the evidence for the hazards involved leads to the conclusion that the continued application of the ten day rule should be strongly recommended as an essential part of good radiological and radiographic practice.

    The aim of this study was to analyze the demographic and clinical characteristics of male breast cancer patients in Serbia, and furthermore to determine overall survival and predictive factors for prognosis. In the period of 1996-2006 histopathological diagnosis of breast cancer was made in 84 males at the Institute for Oncology and Radiology of Serbia. For statistical analyses the Kaplan-Meier method, long-rank test and Cox proportional hazards regression model were used. The mean age at diagnosis with breast cancer was 64.3±10.5 years with a range from 35-84 years. Nearly 80% of the tumors showed ductal histology. About 44% had early tumor stages (I and II) whereas 46.4% and 9.5% of the male exhibited stages III and IV, respectively. Only 7.1% of male patients were grade one. One-fifth of all patients had tumors measuring ≤2 cm, and 14.3% larger than 5 cm. Lymph node metastasis was recorded in 40.4% patients and 47% relapse. Estrogen and progesterone receptor expression was positive in 66.7% and 58.3%, respectively. Among 14.3% of individuals tumor was HER2 positive. About two-thirds of all male patients had radical mastectomy (66.7%). Adjuvant hormonal (tamoxifene), systematic chemotherapy (CMF or FAC) and adjuvant radiotherapy were given to 59.5%, 35.7% and 29.8% patients respectively. Overall survival rates at five and ten years for male breast cancer were 55.0% and 43.9%, respectively. According to the multivariate Cox regression predictive model, a lower initial disease stage, a lower tumor grade, application of adjuvant hormone therapy and no relapse occurrence were significant independent predictors for good overall survival. Results of the treatment would be better if disease is discovered earlier and therefore health education and screening are an imperative in solving this problem.

    Full Text Available A systematical evaluation work was performed on ten widely used and high-efficient QRS detection algorithms in this study, aiming at verifying their performances and usefulness in different application situations. Four experiments were carried on six internationally recognized databases. Firstly, in the test of high-quality ECG database versus low-quality ECG database, for high signal quality database, all ten QRS detection algorithms had very high detection accuracy (F1 >99%, whereas the F1 results decrease significantly for the poor signal-quality ECG signals (all 95% except RS slope algorithm with 94.24% on normal ECG database and 94.44% on arrhythmia database. Thirdly, for the paced rhythm ECG database, all ten algorithms were immune to the paced beats (>94% except the RS slope method, which only output a low F1 result of 78.99%. At last, the detection accuracies had obvious decreases when dealing with the dynamic telehealth ECG signals (all <80% except OKB algorithm with 80.43%. Furthermore, the time costs from analyzing a 10 s ECG segment were given as the quantitative index of the computational complexity. All ten algorithms had high numerical efficiency (all <4 ms except RS slope (94.07 ms and sixth power algorithms (8.25 ms. And OKB algorithm had the highest numerical efficiency (1.54 ms.

    Pain reduction can be achieved by lowering proinflammatory cytokine levels in the blood. Transcutaneous electrical nerve stimulation (TENS) is a non-invasive physiotherapeutic resource for pain management, but evidence on the effectiveness of this device at reducing proinflammatory cytokines in the blood is unclear. This study systematically reviews the literature on the effect of TENS on proinflammatory cytokines. A systematic review protocol was developed based on searches of articles in six electronic databases and references of retrieved articles, contact with authors, and repositories of clinical trials. Eligibility criteria: publication in peer-reviewed journals, randomized clinical trials, use of TENS in the experimental group, and pre- and post-measurements of proinflammatory cytokines in the blood. Selection of the studies and extraction of the data will be carried out by two reviewers independently. Characteristics of the study, participants, interventions and outcomes were extracted and described. Assessments were performed on the risk of bias, level of evidence and the size of the intervention effect in the studies, according to GRADE guidelines and the Cochrane Handbook for Systematic Reviews. Clinical and statistical assessments compared the effects of the interventions (meta-analysis), taking into consideration any influencing characteristics of the studies (e.g., methods and application sites). We anticipate that this review will strengthen evidence-based knowledge of the effect of TENS on proinflammatory cytokines and, as a result, direct new studies to benefit patients with specific pathologies.

  14. Male gametogenesis without centrioles.

    Science.gov (United States)

    Riparbelli, Maria Giovanna; Callaini, Giuliano

    2011-01-15

    The orientation of the mitotic spindle plays a central role in specifying stem cell-renewal by enabling interaction of the daughter cells with external cues: the daughter cell closest to the hub region is instructed to self-renew, whereas the distal one starts to differentiate. Here, we have analyzed male gametogenesis in DSas-4 Drosophila mutants and we have reported that spindle alignment and asymmetric divisions are properly executed in male germline stem cells that lack centrioles. Spermatogonial divisions also correctly proceed in the absence of centrioles, giving rise to cysts of 16 primary spermatocytes. By contrast, abnormal meiotic spindles assemble in primary spermatocytes. These results point to different requirements for centrioles during male gametogenesis of Drosophila. Spindle formation during germ cell mitosis may be successfully supported by an acentrosomal pathway that is inadequate to warrant the proper execution of meiosis. Copyright © 2010 Elsevier Inc.

    Tortoiseshell coat color is normally restricted to female cats due to X-linkage of the gene that encodes the orange coat color. Tortoiseshell male cats do, however, occur at a low frequency among tortoiseshell cats because of chromosome aberrations similar to the Klinefelter syndrome in man...... tissue from a tortoiseshell male cat referred to us. Chromosome analysis using RBA-banding consistently revealed a 39,XXY karyotype. Histological examinations of testis biopsies from this cat showed degeneration of the tubules, hyperplasia of the interstitial tissue, and complete loss of germ cells....... Immunostaining using anti-vimentin and anti-VASA (DDX4) showed that only Sertoli cells and no germ cells were observed in the testicular tubules. As no sign of spermatogenesis was detected, we conclude that this is a classic case of a sterile, male tortoiseshell cat with a 39,XXY chromosome complement. © 2013 S...

    2014-01-01

    Objective: To underline the status of male gender and gall bladder wall thickness as significant risk factors for acute cholecystitis complications. Methods: The retrospective study, with purposive sampling of the patients of acute cholecystits in age above 18 years, who were operated within 10 days of onset of symptoms, was conducted at the Department of Surgery, Dow University Hospital, Karachi, by reviewing the patients' medical record from March 2010 to August 2012. Correlation of incidence of acute cholecystitis complications (empyema and gangrene) to male gender and to the sonographic gall bladder wall thickness more than 4.5mm was analysed using SPSS 16. Result: Out of 62 patients, 8 (13%) patients had gangrene while 10 (16.12%) had empyema. Overall, there were 21 (33.87%) males in the study. Ten (47.6%) of the male patients developed empyema or gangrene of the gall bladder as a complication of acute cholecystitis. Of the 41 (66.12%) female patients, only 8 (19.5%) developed these complications. There were 22 (35.48%) cases of gall bladders with sonographic wall thickness more than 4.5mm who were operated for acute cholecystitis. Of them, 16 (72.7%) had empyema or gangrene. Conclusion: Male gender and sonographic gall bladder wall thickness more than 4.5mm were statistically significant risk factors for suspicion of complicated acute cholecystitis (empyema/gangrene) and by using these risk factors, we can prioritise patients for surgery in the emergency room.

  16. Male contraception: another Holy Grail.

    Murdoch, Fern E; Goldberg, Erwin

    2014-01-15

    The idea that men should participate in family planning by playing an active role in contraception has become more acceptable in recent years. Up to the present the condom and vasectomy have been the main methods of male contraception. There have been and continue to be efforts to develop an acceptable hormonal contraceptive involving testosterone (T) suppression. However the off target affects, delivery of the analogs and the need for T replacement have proven difficult obstacles to this technology. Research into the development of non-hormonal contraception for men is progressing in several laboratories and this will be the subject of the present review. A number of promising targets for the male pill are being investigated. These involve disruption of spermatogenesis by compromising the integrity of the germinal epithelium, interfering with sperm production at the level of meiosis, attacking specific sperm proteins to disrupt fertilizing ability, or interfering with the assembly of seminal fluid components required by ejaculated sperm for acquisition of motility. Blocking contractility of the vas deferens smooth muscle vasculature to prevent ejaculation is a unique approach that prevents sperm from reaching the egg. We shall note the lack of interest by big pharma with most of the support for male contraception provided by the NIH. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

  18. Lycopene and male infertility

    Science.gov (United States)

    Durairajanayagam, Damayanthi; Agarwal, Ashok; Ong, Chloe; Prashast, Pallavi

    2014-01-01

    Excessive amounts of reactive oxygen species (ROS) cause a state of oxidative stress, which result in sperm membrane lipid peroxidation, DNA damage and apoptosis, leading to decreased sperm viability and motility. Elevated levels of ROS are a major cause of idiopathic male factor infertility, which is an increasingly common problem today. Lycopene, the most potent singlet oxygen quencher of all carotenoids, is a possible treatment option for male infertility because of its antioxidant properties. By reacting with and neutralizing free radicals, lycopene could reduce the incidence of oxidative stress and thus, lessen the damage that would otherwise be inflicted on spermatozoa. It is postulated that lycopene may have other beneficial effects via nonoxidative mechanisms in the testis, such as gap junction communication, modulation of gene expression, regulation of the cell cycle and immunoenhancement. Various lycopene supplementation studies conducted on both humans and animals have shown promising results in alleviating male infertility—lipid peroxidation and DNA damage were decreased, while sperm count and viability, and general immunity were increased. Improvement of these parameters indicates a reduction in oxidative stress, and thus the spermatozoa is less vulnerable to oxidative damage, which increases the chances of a normal sperm fertilizing the egg. Human trials have reported improvement in sperm parameters and pregnancy rates with supplementation of 4–8 mg of lycopene daily for 3–12 months. However, further detailed and extensive research is still required to determine the dosage and the usefulness of lycopene as a treatment for male infertility. PMID:24675655

    Full Text Available Rapid prototyping of microchannel gain lots of attention from researchers along with the rapid development of microfluidic technology. The conventional methods carried few disadvantages such as high cost, time consuming, required high operating pressure and temperature and involve expertise in operating the equipment. In this work, new method adapting xurography method is introduced to replace the conventional method of fabrication of microchannels. The novelty in this study is replacing the adhesion film with clear plastic film which was used to cut the design of the microchannel as the material is more suitable for fabricating more complex microchannel design. The microchannel was then mold using polymethyldisiloxane (PDMS and bonded with a clean glass to produce a close microchannel. The microchannel produced had a clean edge indicating good master mold was produced using the cutting plotter and the bonding between the PDMS and glass was good where no leakage was observed. The materials used in this method is cheap and the total time consumed is less than 5 hours where this method is suitable for rapid prototyping of microchannel.

    Cancer pain is difficult to treat, often requiring a multimodal approach. While medication management remains the mainstay for the treatment of cancer pain, medications are often associated with undesired side effects. Transcutaneous electrical nerve stimulation (TENS) provides a potential adjunctive method for treating cancer pain with minimal side effects. Few studies have been performed evaluating the efficacy of TENS on cancer pain. We sought to examine the usefulness of TENS on all cancer patients and to specifically look at the use of TENS as a goal-directed therapy to improve functionality. Retrospective cohort study. Since 2008, patients with chronic cancer pain and on multimodal pain regimens were trialed with TENS. Those patients who showed an improvement in pain symptoms or severity were educated about and provided with a TENS unit for use at home. Pain symptoms and scores were monitored with the visual analog scale (VAS), the numerical rating pain (NRP) scale, and Short-Form McGill Questionnaire at the start of TENS treatment and at 2 months follow-up. TENS proved beneficial in 69.7% of patients over the course of 2 months. In TENS responsive patients, VAS scores decreased by 9.8 on a 0-100 mm scale (P TENS provides a beneficial adjunct for the treatment of cancer pain, especially when utilized as a goal-directed therapy.

    2002-01-01

    The objective of this study was to review ten years of extremity exposure in a growing nuclear pharmacy company and determine those practices that have been most effective in keeping exposures ALARA. The focus of this study was specifically on extremity exposure since whole body exposures have not been as significant. Methods: More than 400 dispensing employees are monitored weekly for extremity exposure. Currently, these employees handle and dispense more than 9,000 Curies (333,000 GBq) of activity ready for use in nuclear medicine procedures each week. The quarterly and annual extremity exposure histories were examined and compared with the introduction of different initiatives to limit these exposures. Changes in the total activity per unit dose were considered as well as the introduction of different compounding practices during this time. An attempt was made to also determine specifically which activities contribute most to the extremity exposure of a dispenser. Procedural changes were reviewed as well as engineering controls such as new shielding materials and designs. Results: A significant conversion of cardiac doses occurred during the time period evaluated. Tc-99m heart agents became the preferred radiopharmaceutical replacing a significant portion of Tl-201 that had been used previously. Tl-201 is still used often in conjunction with a Tc-99m agent. The significance of the switch is the high percentage of dispensed doses for cardiac studies and the higher activities of the Tc-99m agents. A combination of procedural changes and engineering controls (primarily tungsten shielding devices) have been effective in preventing the extremity exposure increase one might expect based on higher activities dispensed per unit dose and the higher energy of Tc-99m compared to Tl-201. One procedural change, the mandatory use of tongs for handling unshielded syringes of radiopharmaceuticals, resulted in a 17% reduction in the average exposure to the extremities

    2002-01-01

    Aim: Since ten years sclerotherapy with ethanol is proposed for the treatment of Plummer's disease (unifocal autonomy). Hence, it was the aim of this study to evaluate critically all the sclerotherapies performed in our institution. Special attention should be given to the long-term results. Material and Methods: In the study enrolled were 47 consecutive patients with Plummer's disease, who were referred to sclerotherapy with ethanol since 1991 (10 men, 37 women, aged 24-79 years). The diagnosis of unifocal autonomy was proven in all patients by scintigraphy under TSH-suppressed conditions. 31 patients had latent, 16 manifest hyperthyroidism, 12 of these under antithyroid medication. All patients received ultrasound guided infiltrations of 0.5-2 ml 96 % ethanol into the autonomy. The procedure was repeated at intervals (individually between 1 week and 3 months) until there was A) sufficient success, B) partial success or C) the patient refused further infiltrations. Results: Overall, 407 infiltrations were performed. The number of infiltrations per patient reached from 1 to 63 (mean 7). The side effects included 2 cases of a (transient) paresis of the recurrent nerve and pain/discomfort in 32 %. The therapy was finished successfully (group A; normal TSH, normalisation of the scintigraphic pattern) in 17 patients, partially successfully (group B; change from manifest to latent hyperthyroidism and/or TSH > 0.1 mU/l, scintigram not completely normalized) in 12 patients, and without success (group C) in 16 patients - 2 changed to surgery, 4 to radioiodine therapy, 3 continued antithyroid medication and 4 refused therapy without further comments. Excluding 2 patients from group B (with 35 and 61 infiltrations, respectively) there was no significant difference between A, B, and C in the parameters uptake under suppression, volume of the autonomy, laboratory values, number of infiltrations, age or sex. Conclusion: The sclerotherapy with ethanol, consequently performed, is

    Located in South central Pacific and despite of its far field situation, the French Polynesia is very much concerned by the tsunamis generated along the major subduction zones located around the Pacific. At the time of writing, 10 tsunamis have been generated in the Pacific Ocean since 2006; all these events recorded in French Polynesia, produced different levels of warning, starting from a simple seismic warning with an information bulletin, up to an effective tsunami warning with evacuation of the coastal zone. These tsunamigenic events represent an invaluable opportunity of evolutions and tests of the tsunami warning system developed in French Polynesia: during the last ten years, the warning rules had evolved from a simple criterion of magnitudes up to the computation of the main seismic source parameters (location, slowness determinant (Newman & Okal, 1998) and focal geometry) using two independent methods: the first one uses an inversion of W-phases (Kanamori & Rivera, 2012) and the second one performs an inversion of long period surface waves (Clément & Reymond, 2014); the source parameters such estimated allow to compute in near real time the expected distributions of tsunami heights (with the help of a super-computer and parallelized codes of numerical simulations). Furthermore, two kinds of numerical modeling are used: the first one, very rapid (performed in about 5minutes of computation time) is based on the Green's law (Jamelot & Reymond, 2015), and a more detailed and precise one that uses classical numerical simulations through nested grids (about 45 minutes of computation time). Consequently, the criteria of tsunami warning are presently based on the expected tsunami heights in the different archipelagos and islands of French Polynesia. This major evolution allows to differentiate and use different levels of warning for the different archipelagos,working in tandem with the Civil Defense. We present the comparison of the historical observed tsunami

    Radionuclide perfusion studies of myocardium are being performed using planar and tomographic (SPECT) procedures. The latter method enables better detection as well as assessment of localisation and severity of scintigraphically visualised perfusion defects. On the other hand, lower cost of planar procedures using 99m Tc-MIBI as the tracer and their much wider availability in countries of Central and Eastern Europe could significantly increase the diagnostic potential of nuclear cardiology in this region.The aim of the study was an assessment of normal distribution of 99m Tc-MIBI in the myocardium and generation of normative basis for quantitative planar scintigraphic procedure, aiming at detection of CAD in patients of both sexes.The study was based on 250 patients. The reference (control) group consisted of 53 individuals (29 men, 24 women) with the low ( 0 and LAO 70 0 ). These mean curves differed significantly between both sexes. In LAO 45 0 projection the differences affected mostly the region of the septum and postero-lateral wall of the left ventricle (LV). In LAO 70 0 projection differences were most pronounced in the antero-septal wall of the LV. Sensitivity, specificity and accuracy of CAD detection using the elaborated method, taking into account inter-sex differences, amounted to 86, 87 and 86% respectively in males, and correspondingly 81, 84 and 83% in females. The differences between corresponding indices for two sexes were statistically insignificant. For the whole group of patients the sensitivity, specificity and accuracy was 85, 86 and 85%, respectively. (author)

    Full Text Available Background: Development of the new methods of treatment of primary male hypogonadism is an urgent medical problem. Its solution requires a suitable experimental model of the disease. Aim: The creation of new experimental model of primary male hypogonadism. Materials and methods: The study was conducted on the male Wistar rats, hypogonadism was modeled by temporary ligation of the distal part of the spermatic cord. Results: It was shown that three-day ligation of the spermatic cord led to persistent disturbance of the testosterone-producing and reproductive functions. These manifestations were reversible at shorter duration of the exposure. Conclusion: The created model of primary male hypogonadism is characterized by the persistent testosterone-producing and reproductive functions disturbance, technical availability, non-toxicity to the other organs and systems. Availability of the model provides new opportunities for the development of approaches to treating diseases of the reproductive organs in men.

    Full Text Available This paper presents an interior point algorithm to solve the multiperiod hydrothermal economic dispatch (HTED. The multiperiod HTED is a large scale nonlinear programming problem. Various optimization methods have been applied to the multiperiod HTED, but most neglect important network characteristics or require decomposition into thermal and hydro subproblems. The algorithm described here exploits the special bordered block diagonal structure and sparsity of the Newton system for the first order necessary conditions to result in a fast efficient algorithm that can account for all network aspects. Applying this new algorithm challenges a conventional method for the use of available hydro resources known as the peak shaving heuristic.

    2012-03-01

    Full Text Available Abstract Background Androgens induce male characters by activating androgen receptors (AR. Previous quantitative studies on AR in fishes have been limited to few tissues and/or a single season/reproductive state. The aim of this investigation was to study the possible role of AR-beta expression levels in the control of male traits in the three-spined stickleback. To that end, AR-beta expression levels in major tissues in breeding and post-breeding male and female sticklebacks were examined. Methods AR-beta mRNA levels were quantified in ten tissues; eye, liver, axial muscle, heart, brain, intestine, ovary, testis, kidney and pectoral muscle in six breeding and post-breeding males and females using reverse transcription quantitative PCR. Results Breeding in contrast to post-breeding males built nests and showed secondary sexual characters (e.g. kidney hypertrophy and elevated androgen levels. Post-breeding females had lower ovarian weights and testosterone levels than breeding females. AR-beta was expressed in all studied tissues in both sexes and reproductive states with the highest expression in the gonads and in the kidneys. The kidney is an androgen target organ in sticklebacks, from which breeding males produce the protein spiggin, which is used in nest-building. There was also high AR-beta expression in the intestine, an organ that appears to take over hyperosmo-regulation in fresh water when the kidney hypertrophies in mature males and largely loses this function. The only tissue that showed effects of sex or reproductive state on AR-beta mRNA levels was the kidneys, where post-breeding males displayed higher AR-beta mRNA levels than breeding males. Conclusion The results indicate that changes in AR-beta mRNA levels play no or little role in changes in androgen dependent traits in the male stickleback.

    Motivation has long been associated with sports engagement. However, to date no research has been performed to understand the domain of motivation among ten-pin bowlers. The purpose of this study was to investigate different types of motivation (i.e., intrinsic vs. extrinsic) based on self-determination theory from the perspective of gender and the bowler type (competitive vs. casual). A total of 240 bowlers (104 male, 136 female; 152 competitive, 88 casual) with a mean age of 16.61 ± 0.78 years were recruited in Kuala Lumpur. The Sport Motivation Scale, a 28-item self-report questionnaire measuring seven subscales (i.e., intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, extrinsic motivation to identify regulation, extrinsic motivation for introjection regulation, extrinsic motivation to external regulation, and amotivation) was administered. Results showed significant differences (t=10.43, df=239, p=0.01) between total scores of intrinsic and extrinsic motivation among ten-pin bowlers. There were significant gender differences with respect to intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, and extrinsic motivation to identify regulation. However, no significant bowler type differences were found for either the intrinsic (t=−1.15, df=238, p=0.25) or extrinsic (t=−0.51, df=238, p=0.61) motivation dimensions. In conclusion, our study demonstrated substantial intrinsic motivation for gender effects, but no bowler type effects among adolescent ten-pin bowlers. PMID:25964827

    Full Text Available Considering the fact that one of the most fundamental tasks of training is developing motoric dimensions of sportsmen, the common goal of this work was to achieve relevant knowledge on the infl uence of ten-day-skiing course on students`* development and to establish their level. The special aim of this work was diagnosing the amount of some of the students` motoric abilities. According to the subjects, problems and goal of the research, there was a hypothesis put: motoric and morphological dimensions of students are coherent with their chrono logical growth and development ten-day-skiing course has signifi cant infl uence on developing some of the students` motoric abilities Besides remaining, the choice of examined samples was put under limits of organizational capacities for realizing researching procedure.It was necessary to insure required devices and standardized conditions under which planned research was supposed to be realized. The sample is taken from students` population implied in regular skiing course. Examined sample consists of thirty male students, each of which is twenty years old. Because of technical and organizational reasons it was not possible to diagnose the whole motoric range of tested students. Due to that a specifi c selection of tests was done and only six variables (that reliably predict levels of motoric abilities on which the training affects were taken: foot tapping, medicine ball throwing, pull-ups with undertaking, trunk lifting in 60 seconds and deep forward band. The level of students` motoric abilities after ten-day-skiing course is on a higher level then initial measuring, and we can certainly claim that it is the result of programmed training process during skiing course. According to the data gained from control and fi nal measuring you can fi nd out the effects of applied resources towards initial measuring.

    Full Text Available Concerns that chemical exposures in the environment have been detrimental to male sexual development and fertility have been heightened by reports of declining sperm counts over the past 50 years. Marked geographic variation has been found in semen quality and in the incidence of testicular cancer and certain urogenital defects. Debate continues over the existence, magnitude and significance of these trends, and how best to evaluate the hypothesis that in utero and childhood exposures to estrogenic compounds may be to blame. Epidemiologic methods for assessing the impact of hazardous substances on male reproductive health have been developed mainly in the area of occupational medicine, and this paper will review the currently recommended methods. These include questionnaires to determine reproductive history and sexual function; reproductive hormone profiles; and semen analyses such as sperm concentration, motility, and morphology. New research tools that show significant promise from the fields of clinical reproductive medicine and reproductive toxicology are discussed as possible additions to epidemiologic studies, including assays of sperm function and genetic integrity, and biomarkers of DNA damage. For population-based studies involving occupational groups or communities with environmental exposures, issues related to the cost, validity, precision and utility of these methods must be carefully considered.Varios artículos publicados informan acerca de una declinación en la concentración de espermatozoides durante los últimos 50 años; lo anterior ha motivado una preocupación creciente en el sentido de que las exposiciones ambientales a diversos químicos actúen en detrimento del desarrollo sexual y de la fertilidad masculina. Se ha observado una marcada variación geográfica en la calidad del semen y en la incidencia del cáncer testicular y diversas malformaciones urogenitales.

    To describe ganglion cysts arising close to the origin of the medial and lateral head of gastrocnemius as identified on magnetic resonance (MR) imaging. We present a series of ten cases of ganglion cysts arising close to the gastrocnemius origin from the medial and lateral femoral condyles. These were collected over a 6-year period from our imaging database. All patients attended for routine MR imaging of the knee with a variety of clinical presentations. Data collected included patient demographics, ganglion size, ganglion site, clinical presentation and ancillary MR imaging findings. The ten patients in this series consisted of seven males and three females, five right and five left knees, age range 27-68 years, mean age 40.6 years. The mean maximal dimension of the ganglion cysts was 26 mm, range 15-40 mm. The medial gastrocnemius origin was involved in eight patients and the lateral origin in two patients. The MR imaging findings consisted of both uni- and multi-loculated cysts, often containing numerous septations with fluid signal characteristics. The cysts were extra-capsular with no clear communication with the joint. One patient presented with a popliteal soft tissue mass and none of the cases required surgical intervention for cyst removal. MR imaging may identify ganglion cysts arising in an intra- or extra-articular site around the knee. This series documents the MR imaging characteristics of ganglion cysts arising close to the gastrocnemius origin and discusses the relevance of this imaging finding. (orig.)

    To review the specific radiological signs of male breast pathology observed in our center over the past five years, as well as the pertinent medical literature. A retrospective study was carried out of the 47 mammographic studies performed in 41 men. Oblique mediolateral and craniocaudal views were employed. The distribution of different types of male breast pathology among our patients was as follows: gynecomastia was detected in 30 cases (73.1%), pseudogynectomastia in 4 (9.7%), carcinoma in 3(7.3%), abscess in 2 (4.9%), lipoma in 1 (2.5%) and epidermoid cyst in the remaining patient (2.5%). The results obtained agree with those reported in the literature reviewed. The most significant findings were the low incidence of carcinoma and the high rate of gynecomastia. (Author) 26 refs

    Full Text Available Ten Fisher rats 50 to 55 days of age made up the pubertal group, and ten rats 90 to 95 days of age served as the controls. The testicular and epididymal weights and volumes of the pubertal males were lower than those of the controls (P0.05. At the beginning of gestation, the pubertal dams weighed less than the controls (P<0.001 but following uterectomy the body weights were equal. Pubertal dams delivered fewer pups than the controls (8.1 ± 2.5 vs 10.4 ± 1.3, P<0.05. There was no difference in the body weights of their offspring or in the weights of their placentas. The results suggest that, in contrast to their female counterparts, pubertal male rats are not fully mature and have not reached complete reproductive capacity at 50-55 days of age.

    1985-07-01

    An 83-year-old man with an endometrioma of the lower abdominal wall has been reported. This occurred following the administration of 25 mg of TACE for a period of about 10 years for what was thought to be carcinoma of the prostate. A second transurethral resection done by Dr. R. C. Thompson proved to be adenocarcinoma. Subsequent to this he was continued on TACE. A review of the more commonly accepted theories of the development of endometriosis in the female has been presented. It is pointed out that the separation between the male and female urogenital systems occurs in the embryo between the eighth week and the fourth month. There is always a possibility for remnants of the opposite sex to remain in individuals. No such was seen in the case which is herein reported. Normal phenotype male was demonstrated in the chromosomal evaluation. A review of the literature on endometriosis in the male reveals several cases which have occurred; the origin of which is though to be from the prostatic utricle which is a remnant of the uterus existing in the male. After a prolonged course the patient reported was followed until he died in 1979. There was no recurrence of the abdominal wall mass but persistent low grade carcinoma of the prostate remained. The terminal process was related to cardiovascular disease and not carcinoma of the prostate. There was delay in publication of this unusual case. The original plan was to await final confirmation of the exact pathologic nature of this condition; unfortunately this was never done since a postmortem examination was not performed.(ABSTRACT TRUNCATED AT 250 WORDS)

    2015-09-01

    Men are increasingly turning to dermatologists and plastic surgeons to request procedures that correct or enhance physical features. With the advent of this emerging new patient population, alterations in preexisting aesthetic techniques, gender-specific uses of existing devices and overall approaches need to be revisited and adapted to obtain results that are suitable for the male patient. Recently, body contouring has become one of the most sought out procedures by men. Although the majority of clinical studies involving body contouring esthetics are performed with female patients, gains from such studies can be extrapolated to men. Body contouring can be broadly classified as non-invasive or invasive, depending on the modality used. Non-invasive contouring is most frequently performed with devices that target subcutaneous adipose with focused electrical or thermal energy, including low-level laser, cryolipolysis, ultrasonography, and radiofrequency. Invasive body contouring modalities useful for male body contouring include liposuction, pectoral and abdominal wall etching, jawline fillers, synthetic deoxycholic acid injections, and solid silicone implants. The purpose of this review is to bring attention to the unique aspects, strategies, and modalities used in aesthetic body contouring for the male patient.

  3. Gender-disturbed males.

    Levine, S B

    1993-01-01

    Adolescent and adult cross-dressing or "transvestism" is the most common antecedent behavioral pattern among those who request sex reassignment surgery. Transvestites are actually a diverse group of men who differ in their gender identities, orientation, and intention. They do, however, have in common a soothing image of themselves as women. Because of this, whether cross-dressing occurs among masculine or feminine males or heterosexuals, homosexuals, bisexuals, or asexuals, or among those with paraphilia, the behavior should be considered the expression of their consciously felt femininity. The confusing differences among cross-dressing males may be explained by their diversity along three dimensions: 1) the ambition for heterosexual intercourse; 2) the natural history of their sexual arousal to female clothing; 3) their current capacity to integrate their masculine and feminine strivings into separate compartments. When cross-dressers give up all vestiges of male gender role behaviors and successfully live and work full time as women, the appropriate descriptive term for them becomes "transsexual."

    Based on the daily price data of spot prices of West Texas Intermediate (WTI) crude oil and ten CSI300 sector indices in China, we apply multifractal detrended cross-correlation analysis (MF-DCCA) method to investigate the cross-correlations between crude oil and Chinese sector stock markets. We find that the strength of multifractality between WTI crude oil and energy sector stock market is the highest, followed by the strength of multifractality between WTI crude oil and financial sector market, which reflects a close connection between energy and financial market. Then we do vector autoregression (VAR) analysis to capture the interdependencies among the multiple time series. By comparing the strength of multifractality for original data and residual errors of VAR model, we get a conclusion that vector auto-regression (VAR) model could not be used to describe the dynamics of the cross-correlations between WTI crude oil and the ten sector stock markets.

    Objective: To investigate the clinical effect of permanent 125 I seeds interstitial implants for metastatic cervical cancer. Methods: Under the guidance of the B-sonography, 125 I seeds were implanted into the eleven cervical lymph nodes of ten patients who had been given tumor resection. The pain relief and tumor size were observed in regular follow-up after one-month treatment. Results: All the patients were followed up for 6-14 months,and the postoperative recovery was good with no complication. One month after the implantation, the pain symptom was alleviated entirely in two nodes and partly in nine nodes. The tumor size shrank in ten nodes while there was no change in one node after one month. Conclusion: Permanent 125 I seeds interstitial implants for metastatic cervical cancer is a safe, minimally invasive and effective treatment. (authors)

    The concentrations and isotopic composition of noble gases have been determined in all ten stone meteorites recovered in Antarctica during 1976-1977 by a U.S.-Japanese expedition. From a comparison of spallogenic and radiogenic gas components it is concluded that the chondrites Mt. Baldr (a) and Mt. Baldr (b) belong to the same fall but that all other stone meteorites are individual finds. (orig.)

    In a 1964 decision the National Health and Medical Research Council recommended that radiological examinations of the lower abdomen and pelvis of women of childbearing age should be confined to the 10-day interval following the onset of menstruation. Recent evidence suggests that the first four weeks from the first day of the last menstrual period is not a critically radiosensitive period and consequently strict adherence to the ten-day rule is no longer indicated.

  18. Elliot Lake uranium mine reclamation, the first ten years

    2000-01-01

    In 1989, Rio Algom Limited finalized its plans for the closure and subsequent decommissioning of two of its then three operating mines in Elliot Lake as a result of market conditions. These two mines closed in August 1990. These mine closures had significant impacts. The principal mining operations of Rio Algom at that time were still in Elliot Lake and had been the very foundation of the company for about 40 years. The business impact on the Corporation was regarded as possibly severe. The resultant layoff of over 1,500 long-term, highly qualified, skilled and well-paid employees, a devastating blow to the affected employees and their families, would have a significant financial impact on the municipal economy, particularly as this announcement was seen as the first step in the early closure of all four operating mines in the region. At that time there was little precedence for such a high profile mine closure program and consequently the many unknowns relating to the mine decommissioning process, legislative requirements and society's expectations resulted in a perception of a significant yet ill-defined liability. In this atmosphere of understandable company, stakeholder and public concern, Rio Algom Limited embarked on what has turned out to be a long, rigorous, challenging yet ultimately reasonable and rewarding process of progressive reclamation of all its Elliot Lake mines, some ten in total (nine uranium, one copper). Over the past ten years, reclamation of all ten mines has been successfully completed, some $70 m plus has been expended in direct site reclamation works and the workforce has been reduced from over 2,500 to just 4. After ten years, the focus of attention is now on the long-term care, maintenance, monitoring and reporting required for the decommissioned mine sites, and the accomplishment of this in the best interests of all the stakeholders.

    Full Text Available Macular amyloidosis is an important cause for cutaneous pigmentation, the aetiology of which is poorly understood. Friction has recently been implicated the causation of early lesions, referred to as frictional amyloidosis. Confirmation of diagnosis by the detect on of amyloid using histochemical stains is inconsistent. Ten patients with pigmentation suggestive of macular amyloidosis were studied with detailed history, clinical examination, biopsy for histochemistry and electron microscopy. Nine out of ten patients had a history of prolonged friction with various objects such as bath sponges, brushes, towels, plant sticks and leaves. Amyloid was demonstrated by histochemical staining in only six out of ten cases. In the remaining four cases, amyloid was detected by electron microscopy. These consisted of aggregates of non-branching, extracellular, intertwining fibres measuring between 200-500 nm in length and between 20-25 nm in diameter. The study confirms the role of friction in the causation of this condition. Histochemical stains are not always successful in the detection of amyloid and electron microscopy is helpful for confirming its presence. The term frictional amyloidosis aptly describes the condition.

    Logic and technical subjects require students to understand basic knowledge in mathematic. For instance, addition, minus, division and multiplication operations need to be mastered by students due to mathematic complexity as the learning mathematic grows higher. Weak foundation in mathematic also contribute to high failure rate in mathematic subjects in schools. In fact, students in primary schools are struggling to learn mathematic because they need to memorize formulas, multiplication or division operations. To date, this study will develop a puppet prototyping for learning mathematic for six to ten digits multiplication. Ten participants involved in the process of developing the prototype in this study. Students involved in the study were those from the intermediate class students whilst teachers were selected based on their vast knowledge and experiences and have more than five years of experience in teaching mathematic. Close participatory analysis will be used in the prototyping process as to fulfil the requirements of the students and teachers whom will use the puppet in learning six to ten digit multiplication in mathematic. Findings showed that, the students had a great time and fun learning experience in learning multiplication and they able to understand the concept of multiplication using puppet. Colour and materials of the puppet also help to attract student attention during learning. Additionally, students able to visualized and able to calculate accurate multiplication value and the puppet help them to recall in multiplying and adding the digits accordingly.

    2015-03-01

    'Exact' quantum dynamics (EQD) calculations of the vibrational spectrum of acetonitrile (CH3CN) are performed, using two different methods: (1) phase-space-truncated momentum-symmetrized Gaussian basis and (2) correlated truncated harmonic oscillator basis. In both cases, a simple classical phase space picture is used to optimize the selection of individual basis functions-leading to drastic reductions in basis size, in comparison with existing methods. Massive parallelization is also employed. Together, these tools-implemented into a single, easy-to-use computer code-enable a calculation of tens of thousands of vibrational states of CH3CN to an accuracy of 0.001-10 cm-1.

    Full Text Available Aims and Background: Iron deficiency is one of the most common nutritional disorders worldwide and blood donation may cause iron depletion. Limited studies with large sample size have been done on male donors. The aim of this study is to determine the prevalence of iron deficiency and iron deficiency anemia among male donors in the Kurdistan Organization of Blood Transfusion in Iran. Materials and Methods: This was a cross-sectional study. Sample size was 1184 blood donors selected by systematic random sampling. Hemoglobin, serum iron, serum ferritin, total iron banding capacity (TIBC and transferin saturation were measured in donors. Iron depletion, lack of iron stores, iron deficiency, iron deficiency anemia and anemia were evaluated among them. Data was analyzed with SPSS software and X΂, one-way ANOVA, and LSD test. Results: Iron deficiency, anemia, iron deficiency anemia, iron depletion and lack of iron resources were seen in 2.3, 4.08, 2.14, 22.76 and 4.66 percent respectively. There was a significant relationship of iron deficiency and iron deficiency anemia with instances of donation and interval from last donation (P < 0.05. A significant relationship was seen between iron deficiency and iron deficiency anemia among blood donors with more than ten times blood donation (P < 0.05. Conclusions: This study showed regular male donors require especial attention. Therefore, serum ferritin is recommended as a more adequate index to use for iron deficiency screening and planning purposes for iron supplementation among them.

  10. THE CHERNOBYL ACCIDENT, THE MALE TO FEMALE RATIO AT BIRTH AND BIRTH RATES

    Directory of Open Access Journals (Sweden)

    Victor Grech

    2014-01-01

    Full Text Available Introduction: The male:female ratio at birth (male births divided by total live births – M/T has been shown to increase in response to ionizing radiation due to gender-biased fetal loss, with excess female loss. M/T rose sharply in 1987 in central-eastern European countries following the Chernobyl accident in 1986. This study analyses M/T and births for the former Soviet Republics and for the countries most contaminated by the event. Methods: Annual birth data was obtained from the World Health Organisation. The countries with the highest exposure levels (by 137Cs were identified from an official publication of the International Atomic Energy Agency. All of the former Soviet states were also analysed and the periods before and after 1986 were compared. Results: Except for the Baltic States, all regions in the former USSR showed a significant rise in M/T from 1986. There were significant rises in M/T in the three most exposed (Belarus, Ukraine and the Russian Federation. The birth deficit in the post-Soviet states for the ten years following Chernobyl was estimated at 2,072,666, of which 1,087,924 are accounted by Belarus and Ukraine alone. Discussion: Chernobyl has resulted in the loss of millions of births, a process that has involved female even more than male fetuses. This is another and oft neglected consequence of widespread population radiation contamination.

  11. Patterns of interventions and the effect of coalitions and sociality on male fitness.

    2012-02-01

    In group living animals, especially among primates, there is consistent evidence that high-ranking males gain a higher reproductive output than low-ranking males. Primate studies have shown that male coalitions and sociality can impact male fitness; however, it remains unclear whether males could potentially increase their fitness by preferentially supporting and socializing with females. Here we investigate patterns of male interventions and the effect of coalitions and sociality on male fitness in rhesus macaques (Macaca mulatta) with particular focus on male-female interactions. We combined behavioural observations collected on Cayo Santiago with genetic data analysed for male reproductive output and relatedness. Our results revealed that the ten top-ranking males provided the majority of all male support observed. In contrast to other primates, male rhesus macaques mainly formed all-down coalitions suggesting that coalitions are less likely used to enhance male dominance. Males supporting females during and before their likely conception were not more likely to fertilize those females. We also found no evidence that males preferably support their offspring or other close kin. Interestingly, the most important predictor of male support was sociality, since opponents sharing a higher sociality index with a given male were more likely to be supported. Furthermore, a high sociality index of a given male-female dyad resulted in a higher probability of paternity. Overall, our results strengthen the evidence that sociality affects fitness in male primates, but also suggest that in species in which males queue for dominance, it is less likely that males derive fitness benefits from coalitions. © 2011 Blackwell Publishing Ltd.

    Full Text Available Objective: To explore the evaluation, treatment and impact of hyperprolactinaemia on male infertility and testicular function, as hyperprolactinaemia is commonly detected during the evaluation of infertile men. Methods: A literature search was performed using MEDLINE/PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines to identify all studies exploring hyperprolactinaemia in male infertility. Results: Elevated levels of serum prolactin have a detrimental effect on male reproduction through inhibition of the pulsatile release of gonadotrophins from the anterior pituitary gland, and a direct effect on spermatogenesis. Treatment of confirmed hyperprolactinaemia with dopamine agonists leads to significant improvements in both semen parameters and hormone levels. Conclusion: Hyperprolactinaemia, both directly and indirectly, has a negative effect on sperm production, and its detection and management in men seeking fertility is mandatory.

    Gynecomastia is defined as an enlargement of the male breast. It is often benign, and can be the source of significant embarrassment and psychological distress. A general medical history and careful physical examination are essential to distinguish normal developmental variants from pathological causes. Treatment is geared toward the specific etiology when identified. In the majority of cases of pubertal gynecomastia, observation and reassurance are the mainstays of therapy as the condition usually resolves naturally. Pharmacological treatment and surgery are recommended only in selected cases. PMID:24872741

    Jannini, Emmanuele A; Blanchard, Ray; Camperio-Ciani, Andrea; Bancroft, John

    2010-10-01

    Debate continues on whether or not male homosexuality (MH) is a result of biological or cultural factors. The debate persists despite the fact that these two sides have different abilities to create a scientific environment to support their cause. Biological theorists produced evidence, however, that these are not always robust. On the other hand, social theorists, without direct evidence confirming their positions, criticize, with good argument, methods and results of the other side. The aim of this Controversy is to understand the reasons of both perspectives. Two scientists (R.B. and A.C.C.) with expertise in the area of biology of MH were asked to contribute their opinions. The nurture position is discussed by a third expert in sexology (J.B.). Expert opinion supported by the critical review of the currently available literature. The role of the Controversy's editor (E.A.J.) is to highlight the strengths and weaknesses of both sides. The two experts of the biological issue answer with their data to the questions: “Is male homosexuality partly explainable by immunology?” and “How is male homosexuality a Darwinian paradox?”, respectively. Genetic and immunological factors, birth order, and fertility of relatives are largely discussed. Finally, the expert sustaining the idea that culture and experiences are important determining factors in sexual orientation used a psychosocial and holistic perspective to explain his position. The JSM's readers should recognize that there are several biological factors in MH. However, these findings do not seem to be able to explain all cases of homosexuality. Some others may be due to particular environmental factors. The issue is complicated and multifactorial, suggesting that further research should be undertaken to produce the final answer to the question raised in this Controversy section.

    Full Text Available Introduction & Objective: Since the elimination of poliomyelitis from Iran, Guillain–Barre Syndrome (GBS has been the leading cause of acute flaccid paralysis. There are a few studies concerning clinical and epidemiologic features of Guillain-Barré syndrome in our country, therefore we evaluated ten years clinical and epidemiologic features of GBS in Sina hospital, Hamadan, Iran.Materials & Methods: In a retrospective descriptive study, we reviewed 80 records of patients with GBS who were hospitalized in Sina Hospital (Hamadan, Iran during 1993-2003. Because of incomplete data we excluded 29 patients from the study. We evaluated clinical and epidemiologic features, risk factors, lab data and management protocols. Complete remission defined as complete improved patient four weeks after the GBS treatment and partial remission as the continuation of the symptom after that time. All the data extracted manually and analyzed with SPSS software.Results: From 51 patients, 36 (70.59% were men and 15 (29.41% women, with a proportion of 2.4 men to 1 woman. The age ranged from 3 to 85 years. The highest frequency was observed in patients aged 11 to 20 (35.28%. 13 patients were student, 11 were house keeper, 11 were farmer, 7 were worker. 29 patients (56.84% had risk factors like respiratory and gastrointestinal track infection, surgery and fever before the disease onset. Complete and partial remission occurred in 17 and 28 patients respectively and 5 patients did not improve. Management failure occurred in 3 (8.83%, 2 (22.23% and 5 (62.5% patients who underwent IVIG, plasmapheresis and corticosteroids respectively.Conclusion: Our data was not similar to other studies in term of male to female proportion, age distribution and management protocols, therefore geographical pattern of the disease should be concerned for better patients’ management.

  18. Ten scenarios from early radiation to late time acceleration with a minimally coupled dark energy

    We consider General Relativity with matter, radiation and a minimally coupled dark energy defined by an equation of state w. Using dynamical system method, we find the equilibrium points of such a theory assuming an expanding Universe and a positive dark energy density. Two of these points correspond to classical radiation and matter dominated epochs for the Universe. For the other points, dark energy mimics matter, radiation or accelerates Universe expansion. We then look for possible sequences of epochs describing a Universe starting with some radiation dominated epoch(s) (mimicked or not by dark energy), then matter dominated epoch(s) (mimicked or not by dark energy) and ending with an accelerated expansion. We find ten sequences able to follow this Universe history without singular behaviour of w at some saddle points. Most of them are new in dark energy literature. To get more than these ten sequences, w has to be singular at some specific saddle equilibrium points. This is an unusual mathematical property of the equation of state in dark energy literature, whose physical consequences tend to be discarded by observations. This thus distinguishes the ten above sequences from an infinity of ways to describe Universe expansion.

Two of these points correspond to classical radiation and matter dominated epochs for the Universe. For the other points, dark energy mimics matter, radiation or accelerates Universe expansion. We then look for possible sequences of epochs describing a Universe starting with some radiation dominated epoch(s) (mimicked or not by dark energy), then matter dominated epoch(s) (mimicked or not by dark energy) and ending with an accelerated expansion. We find ten sequences able to follow this Universe history without singular behaviour of w at some saddle points. Most of them are new in dark energy literature. To get more than these ten sequences, w has to be singular at some specific saddle equilibrium points. This is an unusual mathematical property of the equation of state in dark energy literature, whose physical consequences tend to be discarded by observations. This thus distinguishes the ten above sequences from an infinity of ways to describe Universe expansion

    Orchid taxonimy lags several decades behind the taxonomy of most other large interisting groups of plants. New methods and techiniques, like scanning and transmission electron microscope are rarely applied in orchid's taxonomy. It would be most benefical to orchid taxonomy if a better understanding of the pollinia could be obtained. The main purpose of this research is to study the ultrastructure pollinia of ten species of Aeridinae (Orchidaceae). The scanning electron microscope (SEM) has been used to study the pollinia of ten species of orchids in the substribe Aeridina. This work shows that the ultrastructure of the pollinias are different. Regarding at the number and the surface of pollinia in one flowe, the ten species of Aeridinae can be devided mto three main group: (1) the first group is the flowe with two pollinia with it surface porate : Ascocentrum miniatum; (2) the second group has the same number of pollinia, but with surface cleft : Phalaenopsis. Ph. amboinensis, Ph.cornu-cervi, Ph. Fuscata, Ph. Venosa, Rhychostylis retusa, Vanda limbota, and Vanda insignis: and the third (3)is the flower with four pollinia, unequel : Kingidium deliciosum

  1. Experiencing Male Infertility

    Full Text Available This article examines the qualitative research literature that exists in relation to men’s experiences of male infertility. Since men have often been marginalized in the realm of reproduction, including academic research on infertility, it is important to focus on any qualitative research that gives voices to male perspectives and concerns. Given the distress documented by studies of infertile women, we focus in particular on the emotive responses and lived experiences of men in relation to infertility. In this article then, we present an analysis of the core themes across 19 qualitative articles, which include “infertility as crisis”; “emoting infertility- men as “being strong”’ “infertility as a source of stigma”; and the “desire for fatherhood.” In light of these insights, we identify key areas for future research and development including men’s emotional responses to infertility, how men seek support for infertility, the intersection between masculinity and infertility, the relationship between the desire to father and infertility, and the outcomes of infertility for men in terms of other aspects of their lives. We suggest that such research would facilitate making the experiences of men more central within our understandings of infertility within a field that has primarily been female focused.

    The male urethral imaging and pathology is not widespread in the radiology literature because this part of the urinary tract is easily studied by urologists with clinical or endoscopic examinations. Ultrasonography and MR imaging are increasingly being used in association with voiding cystourethrography and retrograde urethrography. The posterior urethra is being studied with voiding cystourethrography or voiding sonography which allows the detection of bladder neck pathology, post-surgical stenosis, and neoplasms. The functional aspects of the bladder neck and posterior urethra can be monitored continuously in patients with neuromuscular dysfunction of the bladder. The anterior urethral anatomy and pathology is commonly explored by retrograde urethrography, but recently sonourethrography and MR imaging have been proposed, distending the lumen with simple saline solution instead of iodinated contrast media. They are being used to study the urethral mucosa and the periurethral spongy tissue which can be involved in the urethral pathologies such as strictures, diverticula, trauma, and tumors. Imaging has an important role to play in the study of the diseases of the male urethra since it can detect pathology not visible on urethroscopy. The new imaging techniques in this area, such as sonography and MR, can provide adjunct information that cannot be obtained with other modalities. (orig.)

    To analyze the radiological and ultrasonographic signs that contribute to the diagnosis of male breast cancer to establish its differential diagnosis with regard to the most common pathologies involving the male breast. We studied 14 patients diagnosed as heaving breast cancer over the past 23 years. We reviewed their medical records, personal and familial history disease, use of pharmacological agents and the mammographic and ultrasonographic findings. The literature on this subject was also reviewed. Given the fact that his lesion is rare and unexpected in men, a large percentage of the cases, especially those studied in the early years of the study period, involved very advanced stages of the disease at diagnosis. The most common clinical finding was retroarelar mass. Mammography usually reveals a well.defined mass and ultrasound shows a well-defined, hypoechoic, heterogeneous mass. The most frequent histological type is, an in women, the infiltrating ductal carcinoma. A palpable breast mass in a man should suggest possible malignant disease. Thus, mammographic and ultrasonographic studies should be performed early, accompanied, if necessary, by aspiration biopsy; with these measures the prognosis may approximate that of women.

  5. Sexual Selection on male cuticular hydrocarbons via male-male competition and female choice.

    Traditional views of sexual selection assumed that male-male competition and female mate choice work in harmony, selecting upon the same traits in the same direction. However, we now know that this is not always the case and that these two mechanisms often impose conflicting selection on male sexual traits. Cuticular hydrocarbons (CHCs) have been shown to be linked to both social dominance and male attractiveness in several insect species. However, although several studies have estimated the strength and form of sexual selection imposed on male CHCs by female mate choice, none have established whether these chemical traits are also subject to sexual selection via male-male competition. Using a multivariate selection analysis, we estimate and compare sexual selection exerted by male-male competition and female mate choice on male CHC composition in the broad-horned flour beetle Gnatocerus cornutus. We show that male-male competition exerts strong linear selection on both overall CHC abundance and body size in males, while female mate choice exerts a mixture of linear and nonlinear selection, targeting not just the overall amount of CHCs expressed but the relative abundance of specific hydrocarbons as well. We discuss the potential implications of this antagonistic selection with regard to male reproductive success. © 2016 The Authors.

  7. Variation in male mate choice in Drosophila melanogaster.

    Directory of Open Access Journals (Sweden)

    Dominic A Edward

    Full Text Available Male mate choice has been reported in the fruit fly, Drosophila melanogaster, even though males of this species were previously thought to maximise their fitness by mating with all available females. To understand the evolution of male mate choice it is important to understand variation in male mating preferences. Two studies, using different stock populations and different methods, have reported contrasting patterns of variation in male mate choice in D. melanogaster. Two possible explanations are that there are evolved differences in each stock population or that the methods used to measure choice could have biased the results. We investigated these hypotheses here by repeating the methods used in one study in which variable male mate choice was found, using the stock population from the other study in which choice was not variable. The results showed a significant resource-independent male preference for less fecund, smaller females, which contrasts with previous observations of male mate choice. This indicates that different selection pressures between populations have resulted in evolved differences in the expression of male mate choice. It also reveals phenotypic plasticity in male mate choice in response to cues encountered in each choice environment. The results highlight the importance of variation in male mate choice, and of identifying mechanisms in order to understand the evolution of mate choice under varying ecological conditions.

    Extraskeletal mesenchymal chondrosarcoma (EMC) is a rare soft-tissue tumor that most arises in young adults. Because of its rarity, few imaging studies have been reported to date. The purpose of this study was to elucidate the imaging features of this tumor. We conducted a multi-institutional study in cooperation with five referral cancer centers in Japan. Imaging findings of ten new EMC cases, including conventional radiography, computed tomography (CT), and magnetic resonance imaging (MRI), performed at each institute, were reviewed along with clinical features. Ten patients with EMC, who had been treated at each hospital from 1990 to 2001, participated in this study. Soft-tissue masses with well-demarcated, dense and granular calcification were most frequently observed on plain radiographs and CT scans. T2-weighted MR images most clearly depicted a two-component structure composed of calcified and uncalcified areas, and enhanced MRI showed inhomogeneous enhancement in both areas. Although the sensitivity and specificity of these findings are unknown, they might be characteristic and have diagnostic value for this rare tumor. (orig.)

    In 1990, DOE initiated a nationwide evaluation of its Weatherization Program, with assistance from Oak Ridge National Laboratory and an advisory group of 40 weatherization professionals, program managers, and researchers. The evaluation is comprised of three impact studies covering the Program`s major market segments: Single-family homes, mobile homes, and dwellings in small (2 to 4-unit) multifamily buildings (the Single-Family Study), Single-family homes heated primarily with fuel oil (the Fuel-Oil Study), and Dwellings in buildings with five or more units (the Multifamily Study). The Single-Family Study, the subject of this report, is a critical part of this coordinated evaluation effort. Its focus on single-family dwellings, mobile homes, and dwellings in small multifamily buildings covers 83% of the income-eligible population and 96% of the dwellings weatherized during Program Year 1989. The first phase of the Single-Family Study involved the analysis of a massive data base of information collected from 368 local weatherization agencies and 543 electric and gas utilities. This analysis resulted in energy-saving and cost-effectiveness estimates for the Weatherization Program and the identification of a set of ten high-performing agencies located throughout the country. The second phase, which is the subject of this report, involves a ``process`` evaluation of these ten high performers, aimed at identifying those weatherization practices that explain their documented success.

    Omalizumab, an anti-immunoglobulin E monoclonal antibody, has now been used for ten years as an add-on therapy for severe adult atopic asthma, poorly controlled by high-doses inhaled steroids and long-acting beta-agonists. This innovative therapy has been the first biotherapy used on a large scale in severe asthma. It has shown clinical benefits, especially in the prevention of severe exacerbation, with a satisfactory safety profile. Despite its cost, it is an interesting alternative to continuous oral steroids, which cause more long-term side effects. After ten-years of prescription of omalizumab, we review here the mechanism of action, the benefits, the main side effects, the cost-effectiveness and also the alternative indications of this interesting molecule. We also consider the practicalities of using omalizumab, particularly the importance a rigorous assessment of its efficacy after 16 weeks of treatment, and possible future therapeutic indications. Omalizumab has proven its efficacy in large randomized studies but also in real life practice in severe allergic asthma. Copyright © 2015 SPLF. Published by Elsevier Masson SAS. All rights reserved.

  12. Sport and male sexuality.

    Sgrò, P; Di Luigi, L

    2017-09-01

    The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

    2012-02-01

    Full Text Available Abstract Background Central sensitization has recently been documented in patients with knee osteoarthritis (OAk. So far, the presence of central sensitization has not been considered as a confounding factor in studies assessing the pain inhibitory effect of tens on osteoarthritis of the knee. The purpose of this study is to explore the pain inhibitory effect of burst tens in OAk patients and to explore the prognostic value of central sensitization on the pain inhibitory effect of tens in OAk patients. Methods Patients with knee pain due to OAk will be recruited through advertisements in local media. Temporal summation, before and after a heterotopic noxious conditioning stimulation, will be measured. In addition, pain on a numeric rating score, WOMAC subscores for pain and function and global perceived effect will be assessed. Patients will be randomly allocated to one of two treatment groups (tens, sham tens. Follow-up measurements will be scheduled after a period of 6 and 12 weeks. Discussion Tens influences pain through the electrical stimulation of low-threshold A-beta cutaneous fibers. The responsiveness of central pain-signaling neurons of centrally sensitized OAk patients may be augmented to the input of these electrical stimuli. This would encompass an adverse therapy effect of tens. To increase treatment effectiveness it might be interesting to identify a subgroup of symptomatic OAk patients, i.e., non-sensitized patients, who are likely to benefit from burst tens.

    This paper investigates the concern that green buildings may promote energy efficiency and other aspects of sustainability, but not necessarily the health and well-being of occupants through better indoor air quality (IAQ). We ask ten questions to explore IAQ challenges for green buildings as well...... as opportunities to improve IAQ within green buildings and their programs. Our focus is on IAQ, while recognizing that many factors influence human health and the healthfulness of a building. We begin with an overview of green buildings, IAQ, and whether and how green building certifications address IAQ. Next, we...... examine evidence on whether green buildings have better IAQ than comparable conventional buildings. Then, we identify so-called green practices and green products that can have unintended and unfavorable effects on IAQ. Looking ahead, we offer both immediate and longer-term actions, and a set of research...

    Ten organic chemicals were tested for toxicity to four earthworm species: Allolobophora tuberculata, Eisenia fetida, Eudrilus eugeniae and Perionyx excavatus, using the European Economic Community's (EEC) earthworm artificial soil and contact testing procedure. The phenols were the most toxic chemicals tested, followed by the amine, substituted benzenes, halogenated aliphatic hydrocarbon, polycyclic aromatic hydrocarbon and phthalate as the least toxic chemical tested. Correlations among species within each type of test for a given chemical were extremely high, suggesting that the selection of earthworm test species does not markedly affect the assessment of a chemical's toxicity. The correlation between the two tests was low for all test species. The contact test LC50 for a given chemical cannot be directly correlated to an artificial soil test LC50 for the same earthworm species.

    The inability to effectively halt or cure Alzheimer's disease (AD), exacerbated by the recent failures of high-profile clinical trials, emphasizes the urgent need to understand the complex biochemistry of this major neurodegenerative disease. In this paper, ten central, current challenges of the major paradigm in the field, the amyloid hypothesis, are sharply formulated. These challenges together show that new approaches are necessary that address data heterogeneity, increase focus on the proteome level, use available human patient data more actively, account for the aging phenotype as a background model of the disease, unify our understanding of the interplay between genetic and non-genetic risk factors, and combine into one framework both the familial and sporadic forms of the disease.

    The northern part of the Ten Mile and Taunton River basins is an area of about 195 square miles within Norfolk, Plymouth, and Bristol Counties in southeastern Massachusetts. The northern boundary of the area (plate 1) is the drainage divide separating these basins from that of the Charles, Neponset, and Weymouth River basins. The western boundary is, for the most part, the divide separating the basins from the Blackstone River basin. The eastern boundary is at the edge of the Brockton-Pembroke area (Petersen, 1962; Petersen and Shaw, 1961). The southern boundary in Seekonk is the northern limit of the East Providence quadrangle, for which a ground-water map was prepared by Allen and Gorman (1959); eastward, the southern boundaries of the city of Attleboro and the towns of Norton, Easton, and West Bridgewater form the southern boundary of the area.

    Full Text Available According to the empirical and theoretical research in past ten years, the General Factor of Personality (GFP was interpreted as the highest-order (most general personality dimension, which occupies the apex of the structural hierarchy of personality traits. Thus, the GFP is the central concept in the new structural paradigm of personality (the Pyramidal Model of Personality. In the majority of the studies, the GFP was conceptualized as a general factor with substantial psychological (cognitive and behavioural content reflecting the general social and personal adjustment or effectiveness. The alternative explanations of the GFP emphasize the role of the semantic factors, response styles and other biases. This study reviews the main results of the GFP research including the nature, the biological bases, the strength and cultural universality of GFP, its relations to intelligence and other prominent psychological variables, and its predictive power and practical importance.

    2002-03-01

    World-altering discoveries that reveal a universe of uncertainty and constant change Whether probing the farthest reaches of the vast universe or exploring the microscopic world of genetics and the subatomic world of quantum mechanics, Instability Rules is a remarkably informative and engaging look at ten milestone discoveries and their discoverers-a wide range of very human personalities whose insights have dramatically altered our most basic assumptions about human existence during the last century. The stories include Edwin Hubble and the expanding universe, Alfred Wegener and continental drift, Neils Bohr and quantum mechanics, Alan Turing and artificial intelligence, and James Watson and Francis Crick and DNA. Also covering discoveries of the twenty-first century that are already refining these and other ideas, Instability Rules is an exhilarating, sometimes amusing encounter with the defining scientific discoveries of our age.

    The purpose of our study was to compare various aspects of radiology training schemes in ten countries. A questionnaire was sent to senior residents in the UK, USA, Canada, Australia, New Zealand, Italy, Egypt, India, Malaysia and Greece. The questions concerned length of training, required pre-training experience, the organization of the training scheme, teaching, resources, stages at which residents can independently perform and report examinations, fellowships, and progression to jobs. A wide variety of training, ranging from highly scheduled programs with detailed aims and objectives, to self-learning occurs across the world. Examinations and assessments are also variable. There are lessons to be learned from varying practices; more exchanges of ideas should be encouraged. In view of the ''internationalization'' of radiology services and the variation in training styles an international qualification for quality assurance purposes may be desirable. (orig.)

    The switching into actual service of the Chooz plant, the first pressurized water reactor ever built in France, occurred on 3rd april 1967. Ten years later, one can establish a highly positive balance schedule of plant's operation whose availability is satisfactory, except the mechanical failure which occurred during the startup. The behavior of the equipment, in particular of the components of the primary loop, was satisfactory in its whole since it allowed the gradual increase in capacity by 15% with respect to the initial design. It allowed also the achievment of noticeable progress in the design of equipment intended for the new power stations. Interesting results have also been obtained in radioprotection, working conditions of the staff and environment protection fields. Finally, the training of the operating teams has been closely followed, whether it concerned the operators directly affected by plant operation or the trainees gathered in a school specially organized for this purpose and transferred since to a training Center [fr

    This report is intended to discuss the results from the complete technical audit of the vessel effected in 1976 at the Ardennes reactor (CNA 305 MWe). This audit had a special character as far as this power plant has never been inspected before: the start-up had taken place in 1967 and was then prior to the development of French regulations (and even to the first version of the ASME code, Section XI). In that time, no inspection was expected; it has yet been possible to have a complete audit in ten days. The automatic start-up of focused ultrasonic testing so appeared to have reached the required reliability and a good sensitivity [fr

  13. Safe havens in Europe: Switzerland and the ten dwarfs

    Full Text Available Eleven safe havens exist in Europe providing offshore banking and low taxes. Ten of these states are very small while Switzerland is moderately small. All 11countries are richer than their large neighbors. It is shown that causality is from small to safe haven towealth, and that theoretically equilibriums are likely to exist where a certain regulation is substantially lower in a small country than in its big neighbor. This generates a large capital inflow to the safe havens. The pool of funds that may reach the safe havens is shown to be huge. It is far in excess of the absorptive capacity of the safe havens, but it still explains, why they are rich. Microstates offer a veil of anonymity to funds passing through, and Switzerland offers safe storage of funds.

    Full Text Available This paper gives ten best practices for designing mobile applications that have social-networking functions. The need for such an approach is given by the rapid growth in impor-tance of both social networks and mobile applications. In order to make it easy to follow where the best practices come from, the paper starts with a look at why social networks are more than just a buzz word and at how the field of mobile applications is evolving. It also shows how and why the two fields go together so well. To further make the point, there is a case study of four interesting mobile applications that are textbooks examples of successful applications. The best practices are based on research done for this article and on the extensive knowledge of the author.

    The nature of the jets and the role of magnetic fields in gamma-ray bursts (GRBs) remains unclear. In a baryon-dominated jet only weak, tangled fields generated in situ through shocks would be present. In an alternative model, jets are threaded with large-scale magnetic fields that originate at the central engine and that accelerate and collimate the material. To distinguish between the models the degree of polarization in early-time emission must be measured; however, previous claims of gamma-ray polarization have been controversial. Here we report that the early optical emission from GRB 090102 was polarized at 10 +/- 1 per cent, indicating the presence of large-scale fields originating in the expanding fireball. If the degree of polarization and its position angle were variable on timescales shorter than our 60-second exposure, then the peak polarization may have been larger than ten per cent.

    2002-01-01

    The information System on Occupational Exposure (ISOE) was created in 1992 to provide a forum for radiation protection experts from both utilities and national regulatory authorities to discuss, promote and co-ordinate international co-operative undertakings in the area of worker protection at nuclear power plants. The ISOE System is jointly managed by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). This report provides an overview of the experience gained from, and benefits provided by, the ISOE System over the past ten years. Active participation of a large number of utilities in ISOE has contributed to a reduction in occupational exposure at nuclear power plants worldwide. (authors)

    2018-02-01

    This paper develops a methodology to assess the resource requirements of inclusive urban development in India and compares those requirements to current community-wide material and energy flows. Methods include: (a) identifying minimum service level benchmarks for the provision of infrastructure services including housing, electricity and clean cooking fuels; (b) assessing the percentage of homes that lack access to infrastructure or that consume infrastructure services below the identified benchmarks; (c) quantifying the material requirements to provide basic infrastructure services using India-specific design data; and (d) computing material and energy requirements for inclusive development and comparing it with current community-wide material and energy flows. Applying the method to ten Indian cities, we find that: 1%-6% of households do not have electricity, 14%-71% use electricity below the benchmark of 25 kWh capita-month-1 4%-16% lack structurally sound housing; 50%-75% live in floor area less than the benchmark of 8.75 m2 floor area/capita; 10%-65% lack clean cooking fuel; and 6%-60% lack connection to a sewerage system. Across the ten cities examined, to provide basic electricity (25 kWh capita-month-1) to all will require an addition of only 1%-10% in current community-wide electricity use. To provide basic clean LPG fuel (1.2 kg capita-month-1) to all requires an increase of 5%-40% in current community-wide LPG use. Providing permanent shelter (implemented over a ten year period) to populations living in non-permanent housing in Delhi and Chandigarh would require a 6%-14% increase over current annual community-wide cement use. Conversely, to provide permanent housing to all people living in structurally unsound housing and those living in overcrowded housing (social policies that seek to provide basic infrastructure provisioning for all residents would not dramatically increasing current community-wide resource flows.

  18. Ten major trends now emerging in the United States

    1978-01-01

    Using a special analytical procedure for tracking and assessing events reported in the nation's newspapers, the Center for Policy Process has identified ten emerging trends in the United States that are having a major impact on all our lives and on all businesses and industries--and especially on the electric utility industry. Although the trends may move in contradictory directions and have different degrees of significance, all have been carefully monitored for a considerable length of time. All are firmly established--and are not to be viewed as the momentary interests of certain radical elements of the population. The ten trends are: the fast-emerging clash between nuclear fuel and coal as an environmental health issue; displacement of racism and sexism by ''ageism'' as society's most prominent anti-discrimination preoccupation, and the complete elimination soon of mandatory retirement; in government and technology, the phenomenon of ''appropriate scale'' replacing economies of scale, emergence of single-issue political organizations; coming-of-age of the recycling ethic; emergence of ''access to capital'' as the new equity issue--the new rights issue; continuing shift from centralization to decentralization; movement of society in the dual directions of high technology/high touch; business' increasing involvement with the well-established accountability trend; and shift from a representative democracy to a participatory democracy--this profound change in American democracy actually began about a decade or so ago.

    The number of websites for the critical care provider is rapidly growing, including websites that are part of the Free Open Access Med(ical ed)ucation (FOAM) movement. With this rapidly expanding number of websites, critical appraisal is needed to identify quality websites. The last major review of critical care websites was published in 2011, and thus a new review of the websites relevant to the critical care clinician is necessary. A new assessment tool for evaluating critical care medicine education websites, the Critical Care Medical Education Website Quality Evaluation Tool (CCMEWQET), was modified from existing tools. A PubMed and Startpage search from 2007 to 2017 was conducted to identify websites relevant to critical care medicine education. These websites were scored based on the CCMEWQET. Ninety-seven websites relevant for critical care medicine education were identified and scored, and the top ten websites were described in detail. Common types of resources available on these websites included blog posts, podcasts, videos, online journal clubs, and interactive components such as quizzes. Almost one quarter of websites (n = 22) classified themselves as FOAM websites. The top ten websites most often included an editorial process, high-quality and appropriately attributed graphics and multimedia, scored much higher for comprehensiveness and ease of access, and included opportunities for interactive learning. Many excellent online resources for critical care medicine education currently exist, and the number is likely to continue to increase. Opportunities for improvement in many websites include more active engagement of learners, upgrading navigation abilities, incorporating an editorial process, and providing appropriate attribution for graphics and media.

    Six regional medical associations in Shiga prefecture agreed to cooperate in an investigation of medical care for male gonococcal and chlamydial urethritis. In June 2011, we sent a questionnaire to 372 medical offices in Shiga prefecture, and analyzed replies of respondents. Ten urologists and 175 non-urologists responded to the survey (response rate 49.7%). Among 185 physicians, 52 (10 urologists and 42 nonurologists) have treated male patients with gonococcal and chlamydial urethritis. More than 20% (42/175) of non-urological clinics are involved in the medical management. At initial diagnosis for sexually transmitted male urethritis, all urologists select the nucleic acid amplification method (100%), whereas many non-urologists do not (35%). For the treatment of chlamydial urethritis, non-urologists select levofloxacin (LVFX, 52.8%) rather than azithromycin (AZM, 22.0%), whereas urologists use AZM (78.0%) mostly but do not use LVFX (0%) (p = 0.023). For the treatment of gonococcal urethritis, non-urologists prefer oral new quinolones (53.1%) compared to urologists (25.0%) (p = 0. 74). For cure judgment of gonoccocal and chlamydial urethritis, many non-urologists rely on the improvement of subjective symptoms (50 and 47%), but urologists do not (10 and 0%) (p = 0.022 and 0.026, respectively). As for recognition of the clinical guideline for sexually transmitted disease, most urologists (90%) know it, but few non-urologists (13%) do (p urethritis in Shiga prefecture. It is important to standardize the medical care for sexually transmitted male urethritis by familiarizing non-urological practitioners with the clinical guideline.

  3. Coaching the alpha male.

    2004-05-01

    Highly intelligent, confident, and successful, alpha males represent about 70% of all senior executives. Natural leaders, they willingly take on levels of responsibility most rational people would find overwhelming. But many of their quintessential strengths can also make alphas difficult to work with. Their self-confidence can appear domineering. Their high expectations can make them excessively critical. Their unemotional style can keep them from inspiring their teams. That's why alphas need coaching to broaden their interpersonal tool kits while preserving their strengths. Drawing from their experience coaching more than 1,000 senior executives, the authors outline an approach tailored specifically for the alpha. Coaches get the alpha's attention by inundating him with data from 360-degree feedback presented in ways he will find compelling--both hard-boiled metrics and vivid verbatim comments from colleagues about his strengths and weaknesses. A 360-degree assessment is a wake-up call for most alphas, providing undeniable proof that their behavior doesn't work nearly as well as they think it does. That paves the way for a genuine commitment to change. In order to change, the alpha must venture into unfamiliar--and often uncomfortable--psychological territory. He must admit vulnerability, accept accountability not just for his own work for others', connect with his underlying emotions, learn to motivate through a balance of criticism and validation, and become aware of unproductive behavior patterns. The goal of executive coaching is not simply to treat the alpha as an individual problem but to improve the entire team dynamic. Initial success creates an incentive to persevere, and the virtuous cycle reverberates throughout the entire organization.

    Full Text Available Introduction: Despite a recent focus on intimate partner violence (IPV among men who have sex with men (MSM, the male-male couple is largely absent from the IPV literature. Specifically, research on dyadic factors shaping IPV in male-male couples is lacking.Methods: We took a subsample of 403 gay/bisexual men with main partners from a 2011 survey of approximately 1,000 gay and bisexual men from Atlanta. Logistic regression models of recent (,12 month experience and perpetration of physical and sexual IPV examined dyadic factors, including racial differences, age differences, and social network characteristics of couples as key covariates shaping the reporting of IPV.Results: Findings indicate that men were more likely to report perpetration of physical violence if they were a different race to their main partner, whereas main partner age was associated with decreased reporting of physical violence. Having social networks that contained more gay friends was associated with significant reductions in the reporting of IPV, whereas having social networks comprised of sex partners or closeted gay friends was associated with increased reporting of IPV victimization and perpetration.Conclusion: The results point to several unique factors shaping the reporting of IPV within male-male couples and highlight the need for intervention efforts and prevention programs that focus on male couples, a group largely absent from both research and prevention efforts.

    1982-03-01

    The mechanisms causing male sterility in higher plants were classified into two major categories: genetic and non-genetic. The former was further divided into six classes: 1) Anomality in spindle mechanism during meiosis, 2) chromosomal anomality such as haploidy, polyploidy, aneuploidy, chromosome some deficiency, inversion and reciprocal translocation, 3) presence of male sterile genes, 4) cytoplasmic abnormality, 5) the combination of some specific cytoplasm with particular genes, and 6) infections of microorganisms or viruses. Each mechanism was briefly explained, and the methods for the maintenance of parent lines for heterosis breeding and hybrid seed production were described. The non-genetic male sterility was classified into four types, which are caused by 1) low or high temperature, 2) water deficiency, 3) application of chemicals, and 4) radiation, with a brief explanation given for each of them.

    Varicocele is a fairly common condition in male individuals. Although a minor disease, it may cause infertility and testicular pain. Consequently, it has high health and social impact. Here we review the current status of interventional radiology of male varicocele. We describe the radiological anatomy of gonadal veins and the clinical aspects of male varicocele, particularly the physical examination, which includes a new clinical and ultrasound Doppler maneuver. The surgical and radiological treatment options are also described with the focus on retrograde and antegrade sclerotherapy, together with our long experience with these procedures. Last, we compare the outcomes, recurrence and persistence rates, complications, procedure time and cost-effectiveness of each method. It clearly emerges from this analysis that there is a need for randomized multicentre trials designed to compare the various surgical and percutaneous techniques, all of which are aimed at occlusion of the anterior pampiniform plexus.

    Full Text Available Aim: Halitosis is an unpleasant alteration of the halitus. The aim of the study is to assess the quality of sexual life of males with and without halitosis. Material and Method: Males between 20-50 years old; with a complaint of halitosis; married and able to complete the study were included in the study. The control group were healthy, adult, married males who have normal otorhinolaryngologic examination. The International Index of Erectile Function questionnaire(IIEF were used to assess the quality of sexual life  of males with halitosis and the results were compared with a similar group of healthy men. Results: A total of 80 adult subjects completed the study. When the groups were compared in terms of age, body mass index(BMI and duration of marriage, they were similar (p=0.65, p= 0.20, p= 0.08 respectively.The halitosis group had significantly lower scores for all function domains (p=0.0001.There was no correlation between degree of halitosis and the scores of IIEF (p< 0.05. Discussion: This is the first study investigating the sexual health of males with halitosis. Halitosis not only effects oral health status but also strongly declines quality of life. The otorhinolaryngologist must not only treat halitosis but also help the patient to stand up to social and sexual problems concomitting halitosis.

    This study aims to design a transcutaneous electrical nerve stimulation Application (TENS App) according to the suggestions from potential users. To the best of our knowledge, this is the first App including meridian and acupoints for TENS. After its development, there are eight participants recruited for evaluating the usability. Despite two out of eight users reporting that the typical TENS system requires lower cost and has better functionality than TENS App, the results show that almost seventy percent of participants have a better perception of TENS App on price, functionality, convenience, operational ability, and quality. However, participants still reported concerns about the safety issue of adopting TENS App. Therefore, for people who are the first time or unfamiliar with TENS App, instructions from occupational or physical therapists are recommended. We conclude that by using TENS App, users can not only use the portable electrotherapy devices at anyplace, but also reduce their outpatient visits.

    Over the past decade, critical care ultrasound has gained its place in the armamentarium of monitoring tools. A greater understanding of lung, abdominal, and vascular ultrasound plus easier access to portable machines have revolutionised the bedside assessment of our ICU patients. Because ultrasound is not only a diagnostic test, but can also be seen as a component of the physical exam, it has the potential to become the stethoscope of the 21st century. Critical care ultrasound is a combination of simple protocols, with lung ultrasound being a basic application, allowing assessment of urgent diagnoses in combination with therapeutic decisions. The LUCI (Lung Ultrasound in the Critically Ill) consists of the identification of ten signs: the bat sign (pleural line); lung sliding (seashore sign); the A-lines (horizontal artefact); the quad sign and sinusoid sign indicating pleural effusion; the fractal and tissue-like sign indicating lung consolidation; the B-lines and lung rockets indicating interstitial syndromes; abolished lung sliding with the stratosphere sign suggesting pneumothorax; and the lung point indicating pneumothorax. Two more signs, the lung pulse and the dynamic air bronchogram, are used to distinguish atelectasis from pneumonia. The BLUE protocol (Bedside Lung Ultrasound in Emergency) is a fast protocol (respiratory failure. With this protocol, it becomes possible to differentiate between pulmonary oedema, pulmonary embolism, pneumonia, chronic obstructive pulmonary disease, asthma, and pneumothorax, each showing specific ultrasound patterns and profiles. The FALLS protocol (Fluid Administration Limited by Lung Sonography) adapts the BLUE protocol to be used in patients with acute circulatory failure. It makes a sequential search for obstructive, cardiogenic, hypovolemic, and distributive shock using simple real-time echocardiography in combination with lung ultrasound, with the appearance of B-lines considered to be the endpoint for fluid therapy

    Complying with the European and French laws, each year, RTE prepares and publicizes a Ten-Year Network Development Plan (NDP) to meet the expectations of its stakeholders and customers. The NDP lists the network development projects that RTE plans to complete and commission over a 3-year period and presents the main power transmission infrastructure work envisaged for the next Ten-years. Beyond, it outlines the possible network adaptation needs for a variety of energy transition scenarios. Over the next 10 years, the network investments will make it possible to: - Meet the goals of the Regional Climate Air Energy Plans, - Create 4 GW of extra offshore wind generation integration capacity and 10 GW of additional interconnection capacity, 2/3 more than the current capacity, - Enable the development of economically and demographically dynamic areas, with safe and high-standard electricity supply. In the coming decade, RTE plans: - 1,200 km of new underground and sub-sea DC links, along with their associated converter stations; - 600 km of existing equipment upgrades or new overhead 400 kV AC circuits substituting existing power lines. - and, at the same time, nearly 900 km of underground lines and just over 400 km of overhead 225 kV AC lines should be built. 400 projects are listed in this NDP: - 21% of the operations are on overhead lines (for 3/4 new lines or upgrade and for 1/4 dismantling of existing assets) - 27% concern new underground lines; - 52% on substation adaptations (about 20 new RTE substations and 100 new customer substations connected). Globally, nearly 80% of the network is developed underground or sub-sea. This edition of the Network Development plan is further enriched. In particular, it explains more thoroughly the link between the integration of renewable energy and the entailed development of the transmission network. It also provides a focus on smart grids.

    alpha estradiol have been synthesized some of which show selectivity for the central nervous system. CNS effects have been demonstrated in female and male animals. Cardiovascular protection by estrogens has been shown in animal and human studies. Atherosclerotic plaque size was reduced after estrogen injections in cholesterol-fed rabbits. Phytoestrogen-fed monkeys had lower total cholesterol and LDL cholesterol and higher HDL cholesterol. Apart from atherosclerotic lesions, coronary artery vascular reactivity was improved. Some of these experimental findings were confirmed in human studies in postmenopausal women with and without estrogen treatment. Whether all of the described estrogenic effects can be seen in men remains to be investigated. (Med J Indones 2001; 10: 127-33Keywords : aging, andropause, testosterone, estrogens

  15. Use of the sterile male technique as an adjunct to insecticidal and physical methods for stable fly control on the island of St. Croix, U.S.V.I

    A three-year feasibility study was conducted on the island of St. Croix, U.S.V.I., on the use of the sterile male technique as an adjunct to insecticidal and physical measures to control the stable fly, Stomoxys calcitrans L. The native stable fly population cycled in relation to moisture; it was the highest during the rainy season in the autumn (1.9x10 6 ) then gradually declined to a low point (0.7x10 5 ) during the summer in the dry season. The releases were carried out with an indigenous strain of flies reared on the island. The adult flies (24-28-h old) were exposed to 2 kR of gamma irradiation in a cobalt source. This treatment plus marking reduced the competitiveness by about 15%. The sterile flies were released in lots of 4000 at prearranged points throughout the island. Approximately 1x10 5 sterile males/day for 18 months were released at 2 km intervals over the 218 km 2 island. This reduced the native population by about 50%. On selected farms where insecticide or sterile males could not be released, the fly pupal parasite, Spalangia endius Walker, was released. Sanitation and cleanup of breeding habitats were recommended to all farmers, but were practised by very few. When all control techniques were in practice, the native stable fly population was reduced by 99.9%. A few fertile flies were found during the last six months of this experiment. These came from isolated breeding sites, flies immigrating from other islands about 40 km away or were introduced with imported livestock and/or pets. During this period no larval breeding was observed indicating that immigration was probably the main cause of the fertile flies on the island. (author)

  16. Germination and early plant development of ten plant species ...

    Science.gov (United States)

    Ten agronomic plant species were exposed to different concentrations of nano titanium dioxide (nTiO2) or nano cerium oxide (nCeO2) (0, 250, 500 and 1000 mg/L) to examine potential effects on germination and early seedling development. We modified a standard test protocol developed for soluble chemicals (OPPTS 850.4200) to determine if such an approach might be useful for screening engineered nanomaterials (ENMs) and whether there were differences in response across a range of commercially important plant species to two common metal oxide ENMs. Eight of 10 species responded to nTiO2, and 5 species responded to nCeO2. Overall, it appeared that early root growth may be a more sensitive indicator of potential effects from ENM exposure than germination. The observed effects did not always relate to the exposure concentration, indicating that mass-based concentration may not fully explain developmental effects of these two ENMs. The results suggest that nTiO2 and nCeO2 have different effects on early plant growth of agronomic species, which may alter the timing of specific developmental events during their life cycle. In addition, standard germination tests, which are commonly used for toxicity screening of new materials, may not detect the subtle but potentially more important changes associated with early growth and development in terrestrial plants. Engineered nanoparticles (ENMs) have been recognized as valuable components of new technologies and are current

  17. Ten years of KRB Gundremmingen demonstration power station

    Facius, H. von; Ettemeyer, R.

    1976-01-01

    In August 1976 the first large nuclear power station in the Federal Republic, the KRB Gundremmingen plant with a net power of 237 MWe, has been in operation ten years. The construction of KRB as a demonstration plant was a major step forward on the way to the economic utilization of nuclear power for German utilities. Design and operation of the plant have decisively influenced the further development of the technology of light water reactors in the Federal Republic. Unlike the Kahl Experimental Nuclear Power Station (VAK), which was a test facility designed to generate experience and to train personnel, the decision to build KRB from the outset was conditional upon the fulfillment of economic criteria. Here are some of the aspects in which KRB has greatly influenced the development of nuclear power station technology: first application of internal steam-water separation instead of a steam drum with a water content of the steam of less than 1%; construction of a reactor buildung with all the necessary safety factors; solution of the corrosion and erosion problems linked with the use of a saturated steam turbine; special measures taken to prevent the turbine from speeding up due to post-evaporation effects after shutdown. Detailed comments are devoted to the subjects of availability, causes of failure and repair work. (orig.) [de

  18. Strategic Purchasing in Practice: Comparing Ten European Countries.

    2018-02-05

    Strategic purchasing of health care services is widely recommended as a policy instrument. We conducted a review of literature of material drawn from the European Observatory on Health Systems and Policies Health Systems in Transition series, other European Observatory databases, and selected country-specific literature to augment the comparative analysis by providing the most recent healthcare trends in ten selected countries. There is little evidence of purchasing being strategic according to any of the established definitions. There is little or no literature suggesting that existing purchasing mechanisms in Europe deliver improved population health, citizen empowerment, stronger governance and stewardship, or develop purchaser organization and capacity. Strategic purchasing has not generally been implemented. Policymakers considering adopting strategic purchasing policies should be aware of this systemic implementation problem. Policymakers in systems with strategic purchasing built into policy should not assume that a purchasing system is strategic or that it is delivering any expected objectives. However, there are individual components of strategic purchasing that are worth pursuing and can provide benefits to health systems. Copyright © 2018. Published by Elsevier B.V.

    Full text: In this year, our group celebrates ten years of incursions in four-dimensional (3+1) Born and Infeld Electrodynamics (BIE). As is well known, BIE is a classical and nonlinear theory and it predicts a maximum finite value for the electric field, preventing the occurrence of classical singularities. It gives also finite energy for a point-like electric charge. In this period, our main effort was on BIE magnetic sector and the most significant results were: 1. the finite and well behaved magnetostatic field solution for a point-like electric charge at rest, 2. the intrinsic angular momentum (spin) as a self interaction among electric and magnetic field, 3. the cohesive resultant force, using the same natural and simple mechanism, giving stability to the electric charge. Another BIE incursion line stands for three-dimensional (2+1). We investigated the consequences of the space-time dimensionality on the existence of magnetostatic fields generated by electric charges at rest in an inertial frame, which were present in our four-dimensional version. A magnetostatic field associated with an electric charge at rest does not appear in this case. Interestingly, the addition of the topological term (Chern-Simons) to BIE yields the appearance of the magnetostatic field. Finally, we are looking for the hydrogen-like atom spectrum under the BI electrostatic potential, as well the muonic atom spectrum. (author)

  20. WIPP: a perspective from ten years of operating success - 16189

    Gregory, Phillip C.

    2009-01-01

    The Waste Isolation Pilot Plant (WIPP), located 35 miles east of Carlsbad, New Mexico, USA is the first and, to the author's knowledge, only facility in the world for the permanent disposal of defense related transuranic (TRU) waste. Soon after plutonium was first synthesized in 1940 by a team of scientists at the University of California Berkeley Laboratory, the need to find a permanent repository for plutonium contaminated waste was recognized due to the more than 24,000 year half-life of Plutonium-239 ( 239 Pu). In 1957 the National Academy of Sciences published a report recommending deep geological burial in bedded salt as a possible solution. However, more than 50 years passed before the solution was achieved when in 1999 WIPP received the first shipment of TRU waste from Los Alamos National Laboratory. Ten years later, more than 7,600 shipments of TRU waste have been disposed of in rooms mined in an ancient salt bed more than 2,000 feet underground. This paper provides a brief history of WIPP with an overview of the technical, regulatory, and political hurdles that had to be overcome before the idea of a permanent disposal facility became reality. The paper focuses primarily on the safe, uneventful transportation program that has moved 100,000- plus containers of TRU waste from various U.S. Department of Energy (DOE) generator and/or storage sites across the Unites States to southeastern New Mexico.

    Following the radiological accident that happened in Goiania, Brazil, in late 1987, the Brazilian National Nuclear Energy Commission (CNEN) was able to turn to the international community for assistance under the terms of the 1986 IAEA sponsored Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency; this marked the first time the convention was invoked. Additionally, to prevent the loss of useful information, CNEN and the IAEA designated a panel of international experts to investigate the causes and consequences of the accident and draw up a comprehensive report, `The Radiological Accident in Goiania`, which the IAEA published in 1988. Under its nuclear safety programme, it is the IAEA`s intention to follow up serious radiological accidents with review and analysis, to document the causes and circumstances and to disseminate conclusions, lessons to be learned and recommendations from which all States may benefit. A decade after the Goiania accident, the CNEN convened the international conference `Goiania, Ten Years Later` in co-operation with the IAEA. The purpose of this conference was to share with the local population and the international community the knowledge gained during this tragic event and in the following years. The conference attracted some 400 participants from 17 countries (Argentina, Austria, Brazil, Canada, Cuba, El Salvador, Estonia, Germany, Israel, Italy, Mexico, Peru, Russian Federation, Spain, Uruguay, United States of America and Venezuela).

    Dental care of pregnant patients is a demanding task. On one hand, clinicians are facing patients with an altered physiology that may cause a greater need for treatment. On the other hand, pregnancy in itself as well as the unborn child involves potential contraindications to dental interventions. It is therefore essential that dentists be knowledgeable of the ramifications pregnancy has on medical findings and therapy. Also, clinicians must be able to conduct their treatment based on well-grounded data to avoid any harm to the pregnant woman and her unborn child. This article focuses on facts specifically relevant to clinicians. Based on most current scientific data, we aim to answer the following ten questions: 1. What are the physiological changes during pregnancy? 2. What is the adequate lying position for a pregnant patient? 3. Is there a pregnancy-related gingivitis? 4. What is the association between periodontitis, pregnancy and preterm birth? 5. Are there oral manifestations of pregnancy-related therapies? 6. Are caries and erosions inevitable during pregnancy? 7. Should the intake of fluoride be advocated? 8. Is it permissible to x-ray pregnant patients? 9. Is orthodontics contraindicated during pregnancy and 10. Which medication should be administered with caution?

  4. Chern-Simons gauge theory: Ten years after

    1999-01-01

    A brief review on the progress made in the study of Chern-Simons gauge theory since its relation to knot theory was discovered ten years ago is presented. Emphasis is made on the analysis of the perturbative study of the theory and its connection to the theory of Vassiliev invariants. It is described how the study of the quantum field theory for three different gauge fixings leads to three different representations for Vassiliev invariants. Two of these gauge fixings lead to well known representations: the covariant Landau gauge corresponds to the configuration space integrals while the non-covariant light-cone gauge to the Kontsevich integral. The progress made in the analysis of the third gauge fixing, the non-covariant temporal gauge, is described in detail. In this case one obtains combinatorial expressions, instead of integral ones, for Vassiliev invariants. The approach based on this last gauge fixing seems very promising to obtain a full combinatorial formula. We collect the combinatorial expressions for all the Vassiliev invariants up to order four which have been obtained in this approach

    Disposable cups can be made from conventional petro-plastics, bioplastics, or paperboard (coated with petro-plastics or bioplastics). This study compared ten life cycle assessment (LCA) studies of disposable cups with the aim to evaluate the robustness of their results. The selected studies have only one impact category in common, namely climate change with global warming potential (GWP) as its category indicator. Quantitative GWP results of the studies were closer examined. GWPs within and across each study show none of the cup materials to be consistently better than the others. Comparison of the absolute GWPs (after correction for the cup volume) also shows no consistent better or worse cup material. An evaluation of the methodological choices and the data sets used in the studies revealed their influence on the GWP. The differences in GWP can be attributed to a multitude of factors, i.e., cup material and weight, production processes, waste processes, allocation options, and data used. These factors basically represent different types of uncertainty. Sensitivity and scenario analyses provided only the influence of one factor at once. A systematic and simultaneous use of sensitivity and scenario analyses could, in a next research, result in more robust outcomes. -- Highlights: • Conflicting results from life cycle assessment (LCA) on disposable cups • GWP results of LCAs did not point to a best or worst cup material. • Differences in GWP results are due to methodological choices and data sets used. • Standardized LCA: transparency of LCA studies, but still different in approaches.

    The Holistic System of Care for Native Americans in an Urban Environment is a community-focused intervention that provides behavioral health care, promotes health, and prevents disease. This approach is based on a community strategic planning process that honored Native American culture and relationships. Substance abuse, mental illness, homelessness, poverty, crime, physical illness, and violence are symptoms of historical trauma, family dysfunction, and spiritual imbalance. The holistic model links treatment, prevention, and recovery. The link between prevention and treatment is early intervention. Peer support is the link between treatment and recovery. Recovering individuals serve as role models linking recovery to prevention. Culture and spirituality build a strong and resilient foundation for recovery. This article documents the effectiveness of the holistic model over a ten-year period that it has been implemented at the Family & Child Guidance Clinic of the Native American Health Center in the San Francisco Bay Area. The holistic model has produced statistically significant reductions in substance abuse among adult Native American women, men, reentry, and homeless populations; reductions in substance abuse among Native American adolescents; reductions in HIV/AIDS high-risk behavior among Native American men, women, and adolescents; and decreases in acting out behavior among Native American severely emotionally disturbed children.

  7. Lateral patellar retinacular release: changes over the last ten years

    Directory of Open Access Journals (Sweden)

    Leonardo Pini Rosalem Marciano da Fonseca

    Full Text Available ABSTRACT Lateral retinacular release is a useful resource in knee surgery that can be used for disorders of the extensor mechanism. For many years, it was indiscriminately used in the treatment of the various patellofemoral joint alterations, with conflicting functional results. This study aimed to analyze the changes that have occurred in the indications and clinical effectiveness of lateral retinacular release by reviewing the relevant literature of the past ten years, comparing it to the classic literature on the subject. It was found that less extensive releases decompress the lateral patellar facet, helping with pain control, while decreasing the risks of medial subluxation. Nowadays, there is clear evidence for its indication in the lateral patellar hypercompression syndrome associated with anterior knee pain, as long as there is no related instability; furthermore, it will normally play an adjuvant role in extensor mechanism alignment surgeries for cases of recurrent patellar instability. The initial results for symptomatic patellofemoral osteoarthritis are promising when lateral release is combined with cartilage debridement; in total knee replacement, it is more commonly used for the correction of valgus deformity in order to improve the components’ congruency. Finally, distinguishing the different patellofemoral joint pathologies is seen as crucial in order to indicate this procedure. Further randomized control trials that compare surgical techniques with long-term results are still needed.

    Full Text Available Background: This paper analyzes progress made toward the integration of the French health care system for the older and chronically ill population. Policies: Over the last ten years, the French health care system has been principally influenced by two competing linkage models that failed to integrate social and health care services: local information and coordination centers, governed by the social field, and the gerontological health networks governed by the health field. In response to this fragmentation, Homes for the Integration and Autonomy for Alzheimer patients (MAIAs is currently being implemented at experimental sites in the French national Alzheimer plan, using an evidence-based model of integrated care. In addition, the state's reforms recently created regional health agencies (ARSs by merging seven strategic institutions to manage the overall delivery of care. Conclusion: The French health care system is moving from a linkage-based model to a more integrated care system. We draw some early lessons from these changes, including the importance of national leadership and governance and a change management strategy that uses both top-down and bottom-up approaches to implement these reforms.

    1996-11-01

    Changes which have taken place in the Canadian natural gas market in the ten years since the gas market was de-regulated, were reviewed. A 1985 agreement created conditions for a competitive natural gas market. However, the National Energy Board ensured that the pipeline transmission sector of the gas industry would continue to be regulated because of its natural monopoly characteristics. Open non-discriminatory access was to be provided to all shippers on inter-provincial gas pipelines. One objective of this report was to provide the Board with the means of assuring itself that the market was operating in such a way that Canadian requirements for natural gas were being met at fair market prices. The report also provided a review of the major changes in the gas producing and transmission sector, and reviewed developments in gas markets and sales practices. The overall assessment was that the natural gas industry was efficient and responsive to the demands of the marketplace. 5 tabs., 30 figs

    Paediatric tracheobronchomalacia is a rare but potentially serious condition. Severe tracheobronchomalacia requires intervention or operation. This is an evaluation of a ten-year experience at an institution. In this retrospective study all patients were included that required an intervention for severe tracheobronchomalacia from 2003 to 2012. Symptoms, aetiology, comorbidities, localisation of the malacia, age at diagnosis, therapeutic measures and associated complications were evaluated. Forty-four patients with severe tracheobronchomalacia underwent intervention/operation. The predominant aetiology was vascular compression in 48%. The majority of patients had complex comorbidities, most importantly cardiac pathology in 66%. The median age at diagnosis was 3 months. A total of 17 aortopexies, 21 tracheostomies and 25 stent placements were performed. The mean follow-up was 2.6 years. Severe complications occurred in 12 patients. The most common complications were stent obstruction/fracture and tracheostomy tube obstruction. The management of severe tracheobronchomalacia is complex and the population of patients is very heterogeneous. Therefore the treatment has to be adapted for each patient individually. The decision strategies are discussed in this article. The surgical techniques for placement and safe removal of expandable bare metallic stents employed in our institution are presented. A multidisciplinary team of ENT surgeons, Intensivists, Cardiologists and Cardiac surgeons is of great importance. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available The widely held constructivist view of learning advocates student engagement via interactivity. Within the physics education research community, several specific interactive strategies have been developed to enhance conceptual understanding. One such strategy, the Interactive Lecture Demonstration (ILD is designed for large lecture classes and, if measured using specific conceptual surveys, is purported to provide learning gains of up to 80%. This paper reports on learning gains for two different Projects over ten years. In Project 1, the ILDs were implemented from 1999 to 2001 with students who had successfully completed senior high school physics. The learning gains for students not exposed to the ILDs were in the range 13% to 16% while those for students exposed to the ILDs was 31% to 50%. In Project 2, the ILDs were implemented from 2007 to 2009 with students who had not studied senior high school physics. Since the use of ILDs in Project 1 had produced positive results, ethical considerations dictated that all students be exposed to ILDs. The learning gains were from 28% to 42%. On the one hand it is pleasing to note that there is an increase in learning gains, yet on the other, we note that the gains are nowhere near the claimed 80%. This paper also reports on teacher experiences of using the ILDs, in Project 2.

    2018-03-01

    Producing microchannels with diameters between 10 and 20 μm and with lengths in the tens of centimeters is reported. The method can be modified to obtain diameters as narrow as 350 nm. Length-to-diameter aspect ratios that surpass 104 can be produced for a fraction of current production costs. The controllable channel is produced by applying a flame to the narrow end of a commercial pipette that is made from a soda-lime silicate. In combination with a pulling mechanism, applying heat to the composite material lengthens the pipette in a highly uniform way. Given that the materials and methods in this research are cost-effective when compared to femtosecond laser micromachining on 2D silicon-based surfaces, further research into producing microchannels from soda-lime silicates may revolutionize access to 3D controllable microchannels.

It shows how the commonplace connection of John Christie to abortion and Beryl Evan's death was not a given in the wider public, legal, political, and forensic imagination of the time, reflecting the multi-layered and shifting meanings of abortion from the date of the original trials in the late 1940s and 1950s, through the subsequent judicial and literary reinvestigations of the case in the 1960s, to its cinematic interpretation in the 1970s. Exploring the language of abortion used in these different contexts, the article reveals changes in the gendering of abortionists, the increasing power and presence of abortion activists and other social reformers, the changing representation of working-class women and men, and the increasing critique of the practice of backstreet abortion. The case is also made for a kind of societal blind spot on abortion at the time of both the Evans and Christie trials; in particular, a reluctance to come to terms with the concept of the male abortionist, which distorted the criminal investigations and the trials themselves. Only when public acceptance for legalizing abortion grew in the more liberal climate of the 1960s and beyond did a revisionist understanding of the murder of Beryl Evans, in which abortion came to be positioned as a central element, gain a sustained hearing.

    Considerable research on African American males (AAMs) in American schools over the past ten years shows that they are underrepresented in every positive measure of educational outcomes, and overrepresented in every negative measure.
