Background

Previous studies have shown that the practice of yoga reduces perceived stress and negative feelings and that it improves psychological symptoms. Our previous study also suggested that long-term yoga training improves stress-related psychological symptoms such as anxiety and anger. However, little is known about the beneficial effects of yoga practice on somatization, the most common stress-related physical symptoms, and stress-related biomarkers. We performed a prospective, single arm study to examine the beneficial effects of 12 weeks of yoga training on somatization, psychological symptoms, and stress-related biomarkers.

Methods

We recruited healthy women who had no experience with yoga. The data of 24 participants who were followed during 12 weeks of yoga training were analyzed. Somatization and psychological symptoms were assessed before and after 12 weeks of yoga training using the Profile of Mood State (POMS) and the Symptom Checklist-90-Revised (SCL-90-R) questionnaires. Urinary 8-hydroxydeoxyguanosine (8-OHdG), biopyrrin, and cortisol levels were measured as stress-related biomarkers. The Wilcoxon signed-rank test was used to compare the stress-related biomarkers and the scores of questionnaires before and after 12 weeks of yoga training.

Results

After 12 weeks of yoga training, all negative subscale scores (tension-anxiety, depression, anger-hostility, fatigue, and confusion) from the POMS and somatization, anxiety, depression, and hostility from the SCL-90-R were significantly decreased compared with those before starting yoga training. Contrary to our expectation, the urinary 8-OHdG concentration after 12 weeks of yoga training showed a significant increase compared with that before starting yoga training. No significant changes were observed in the levels of urinary biopyrrin and cortisol after the 12 weeks of yoga training.

Conclusions

Yoga training has the potential to reduce the somatization score and the scores related to mental health indicators, such as anxiety, depression, anger, and fatigue. The present findings suggest that yoga can improve somatization and mental health status and has implications for the prevention of psychosomatic symptoms in healthy women.

Background

Male infertility is a widespread condition among couples. In about 50% of cases, couple infertility is attributable to the male partner, mainly due to a failure in spermatogenesis. In recent times, the crucial role that modifiable lifestyle factors play in the development of infertility have generated a growing interest in this field of study, i.e. aging, psychological stress, nutrition, physical activity, caffeine, high scrotal temperature, hot water, mobile telephone use. Several studies have investigated associations between semen quality and the presence of lifestyle stressors i.e. occupational, life events (war, earthquake, etc.) or couple infertility; overall, these studies provide evidence that semen quality is impaired by psychological stress. In this review, we will discuss the impact of quality of life (modifiable lifestyle factors) and psychological stress on male fertility. In addition, the role that increased scrotal temperature along with inappropriate nutritional and physical exercise attitudes exert on male fertility will be presented.

Conclusion

The decline of male fertility, particularly associated with advancing age, incorrect lifestyles and environmental factors plays an important role on natality, and its consequences on the future on human population makes this an important public health issue in this century. Thus, modification of lifestyle through a structured program of educational, environmental, nutritional/physical exercise and psychological support, combined with the use of nutraceutical antioxidants can prevent infertility and therefore, may help couples to obtain better quality of life and improved possibility to conceive spontaneously or optimize their chances of conception.

Although anthropologists have paid little attention to popular American psychological discourse about addiction and recovery, the cultural politics of its engagement by Native North American communities warrant closer examination. By ethnographically contextualizing personal narratives, this paper describes how addiction/recovery discourse has been selectively engaged by younger generations of women in a northern Plains reservation community. Sobriety is not only a therapeutic transformation but also a socially negotiated identity change in this community and, therefore, engages ongoing local identity politics. Many community members evaluate the legitimacy of claims to Native identity by essentializing boundaries between Native and non-Native, as well as between past and present-a discursive convention that O'Nell has called "the rhetoric of the empty center" (Disciplined Hearts: History, Identity and Depression in an American Indian Community. Berkeley: University of California Press, 1996, p. 55). Yet by selectively appropriating elements of addiction/recovery discourse, younger women in the 1990s increasingly positioned emotional experience and expression as central arbiters of the legitimacy of Native identity. In so doing, they reconfigured the rhetoric of the empty center, eliciting both controversy and support from the larger community. This analysis highlights new dimensions of the social life of addiction/recovery discourse in contemporary Native North America, and calls for increased ethnographic attention to how localized cultural politics can orient the ways in which communities engage therapeutic discourses.  相似文献

Phenotype‐linked fertility hypothesis (PLFH) predicts that male secondary sexual traits reveal honest information about male fertilization ability. However, PLFH has rarely been studied in humans. The aim of the present study was to test PLFH in humans and to investigate whether potential ability to select fertile partners is independent of sex or cultural background. We found that on the contrary to the hypothesis, facial masculinity was negatively associated with semen quality. As increased levels of testosterone have been demonstrated to impair sperm production, this finding may indicate a trade‐off between investments in secondary sexual signalling (i.e. facial masculinity) and fertility or status‐dependent differences in investments in semen quality. In both sexes and nationalities (Spanish and Colombian), ranked male facial attractiveness predicted male semen quality. However, Spanish males and females estimated facial images generally more attractive (gave higher ranks) than Colombian raters, and in both nationalities, males gave higher ranks than females. This suggests that male facial cues may provide culture‐ and sex‐independent information about male fertility. However, our results also indicate that humans may be more sensitive to facial attractiveness cues within their own populations and also that males may generally overestimate the attractiveness of other men to females.  相似文献

Transsexual patients can only be diagnosed and treated at functional gender identity Units with provision of high quality care, development of clinical practice guidelines, and interdisciplinary working groups. The therapeutic process has three mainstays: initial psychological diagnostic evaluation and psychotherapy, endocrinological evaluation and hormone therapy, and sex reassignment surgery. Cross-sex hormone therapy is essential for the anatomical and psychological transition process in duly selected patients. Hormones help optimize real-life sex identity, improve quality of life, and limit psychiatric co-morbidities often associated to lack of treatment. Development of this clinical practice guideline addresses the need for implementing a coordinated action protocol for comprehensive health care for transgender people in the National Health System.  相似文献

Females of the grasshopper Chorthippus biguttulus invest much more in the offspring than do males. As a consequence, females are the more selective sex and exert a sexual selection on males by responding to the songs of certain conspecific males while rejecting others. What kind of information about the sender may a female obtain from a male’s song, in addition to its species identity? We searched for correlations between a series of song features and morphometric parameters of individual males. In addition, also the immunocompetence of males was assessed by implanting small pieces of nylon thread. We found significant, positive correlations between certain song characteristics and indicators of male size and immunocompetence. Thus, grasshopper females may—in principle—be able to judge a male’s condition and health from the acoustic signals he produces.  相似文献

Psychological terms, such as 'mind', 'memory', 'emotion' and indeed 'psychology' itself, have a history. This history, I argue, supports the view that basic psychological categories refer to historical and social entities, and not to 'natural kinds'. The case is argued through a wide ranging review of the historiography of western psychology, first, in connection with the field's extreme modern diversity; second, in relation to the possible antecedents of the field in the early modern period; and lastly, through a brief introduction to usage of the words 'soul', 'mind', 'memory' and 'emotion'. The discussion situates the history of psychology within a large historical context, questions assumptions about the continuity of meaning, and draws out implications for the philosophical and social constitution of 'psychology' and 'the psychological' from the existing literature. The historical evidence, this paper concludes, does not support the conventional presumption that modern psychological terms describe 'natural kinds'.  相似文献

Background and Objectives

Experimental models show a male bias in murine malaria; however, extant literature on biases in human clinical malaria is inconclusive. Studies in hyperendemic areas document an absence of sexual dimorphism in clinical malaria. Data on sex bias in clinical malaria in hypoendemic areas is ambiguous—some reports note a male bias but do not investigate the role of differential mosquito exposure in that bias. Moreover, these studies do not examine whether the bias is age related. This study investigates whether clinical malaria in hypoendemic regions exhibits a sex bias and whether this bias is age-dependent. We also consider the role of vector exposure in this bias.

Methods

Retrospective passive clinical malaria datasets (2002–2007) and active surveillance datasets (2000–2009) were captured for the hypoendemic Mumbai region in Western India. To validate findings, passive retrospective data was captured from a primary malaria clinic (2006–2007) in hypoendemic Rourkela (Eastern India). Data was normalized by determining percent slide-positivity rates (SPRs) for males and females, and parasite-positivity distributions were established across age groups. The Mann–Whitney test, Wilcoxon Signed Rank test, and Chi-square analysis were used to determine statistical significances.

Results

In both the Mumbai and Rourkela regions, clinical malaria exhibited an adult male bias (p<0.01). A sex bias was not observed in children aged ≤10. Post-puberty, male SPRs were significantly greater than females SPRs (p<0.01). This adult male bias was observed for both vivax and falciparum clinical disease. Analysis of active surveillance data did not reveal an age or sex bias in the frequency of parasite positivity.

Conclusion

This study demonstrates an age-dependent sex bias in clinical malaria in hypoendemic regions and enhanced incidence of clinical malaria in males following puberty. Possible roles of sex hormones, vector exposure, co-infections, and other factors in this enhanced susceptibility are discussed.  相似文献

Summary We describe a new type of desynapsis observed in the semen samples and/or testicular biopsies from four subfertile patients. The desynaptic anomaly affects one or more bivalents in each cell. The incidence of this meiotic anomaly in our series of subfertile males (925 meiotic studies by May 1981) is about 0.43%.The different types of oligochiasmatic meiotic mutation described in human subfertile males are classified according to our data and those published in the literature.  相似文献

Several lines of circumstantial evidence suggest that we may be seeing adverse changes in male reproductive health. A possible decline in semen quality has attracted most attention, but there are stronger indications of a rising incidence of testicular cancer, with increases observed in both Europe and the USA. There are striking geographic variations in both the incidence of testis cancer and in the observed rate of increase, and it is noteworthy that testis cancer is much more common in Denmark, where low sperm counts have been reported, than in Finland, where semen quality seems to be better. Another cause for concern is the rising incidence of congenital malformations of the male genital tract — cryptorchidism and hypospadias. In the UK, for example, rates of cryptorchidism have increased by as much as 65 to 77%. The data are harder to interpret on semen quality. In a meta-analysis, Carlsen et al. (1992) identified significant decreases over time in sperm concentration, corresponding to a fall of almost 50% between 1940 and 1990. Several groups have since examined secular trends in semen quality, with some reporting a downward trend and others no change. However, evidence has emerged of striking regional differences in semen quality, whether due to ethnic, genetic, environmental, or lifestyle factors remains to be determined.  相似文献

This study assessed the effect of alternate nostril yoga breathing (nadisuddhi pranayama) on P300 auditory evoked potentials compared to a session of breath awareness of equal duration, in 20 male adult volunteers who had an experience of yoga breathing practices for more than three months. Peak amplitudes and peak latencies of the P300 were assessed before and after the respective sessions. There was a significant increase in the P300 peak amplitudes at Fz, Cz, and Pz and a significant decrease in the peak latency at Fz alone following alternate nostril yoga breathing. Following breath awareness there was a significant increase in the peak amplitude of P300 at Cz. This suggests that alternate nostril yoga breathing positively influences cognitive processes which are required for sustained attention at different scalp sites (frontal, vertex and parietal), whereas breath awareness brings about changes at the vertex alone.  相似文献

Over the last couple of generations, we have been exposed to an increasing number of endocrine disrupters in our environment, including dichlorodiphenyltrichloroethane (DDT), PCB, certain pesticides, the phthalate DBP, synthetic steroids in meat and many other agents (table 1), which act as agonists or antagonists of sex steroids. Although biologists working with wildlife have been concerned about the possible effects of these chemical agents on animal reproduction, it appears that clinicians have been less concerned about possible health effects in humans. However, the increasing incidence of hormone-dependent cancers, including cancer of the breast, prostate and testis, and signs of an increasing incidence of male reproductive health problems should alert us to the possible association between exposure to endocrine disrupters and the current high frequency of reproductive problems. In Denmark, for example, 5% of all children are now born after assisted reproduction (intracytoplasmic sperm injection, in vitro fertilization, donor insemination and intrauterine insemination) and 1% of all (mostly young) men develop testicular cancer. Evidence exists to support the concept that hypospadias, undescended testis, poor semen quality and testicular cancer are symptoms of an underlying testicular dysgenesis syndrome, which may be becoming increasingly common due to adverse environmental effects. Experimental and epidemiological evidence suggests that testicular dysgenesis syndrome is a result of disruption of foetal programming and gonadal development during foetal life.  相似文献

The concept "functional state" is discussing with attraction notion about fundamental components of live organism: substance, structure, production of energy and information, entropy. In the specified terms is giving working definition of functional condition. From such of positions the normal functional state, and its making--physiological state and psychological state, is considered.  相似文献

OBJECTIVE--To determine whether the sex differences in access to cardiac surgery observed in the United States exist in the United Kingdom. DESIGN--Retrospective analysis of routinely collected data. SETTING--South West Thames and North West Thames regional health authorities. SUBJECTS--8564 patients discharged from hospital with a principal diagnosis of coronary heart disease in 1987-8 in South West Thames region and 15243 discharges in North West Thames region in 1990-1. MAIN OUTCOME MEASURES--Performance of angiography or coronary artery bypass surgery. RESULTS--In all age groups and among patients with a principal diagnosis of either angina or chronic ischaemia men were significantly more likely than women to undergo revascularisation in both regions. Using multiple logistic regression to control for potential clinical and demographic confounders, the male to female odds ratio for revascularisation among all cases was 1.59 (95% confidence interval 1.25 to 2.03) in South West Thames region and 1.47 (1.32 to 1.63) in North West Thames region. CONCLUSION--There appears to be a systematic difference in the treatment received by men and women in the United Kingdom. The reasons for this are uncertain.  相似文献

Increasing alcohol consumption among older individuals is a public health concern. Lay understandings of health risks and stigma around alcohol problems may explain why public health messages have not reduced rates of heavy drinking in this sector. A qualitative study aimed to elucidate older people''s reasoning about drinking in later life and how this interacted with health concerns, in order to inform future, targeted, prevention in this group. In 2010 a diverse sample of older adults in North East England (ages 50–95) participated in interviews (n = 24, 12 male, 12 female) and three focus groups (participants n = 27, 6 male, 21 female). Data were analysed using grounded theory and discursive psychology methods. When talking about alcohol use older people oriented strongly towards opposed identities of normal or problematic drinker, defined by propriety rather than health considerations. Each of these identities could be applied in older people''s accounts of either moderate or heavy drinking. Older adults portrayed drinking less alcohol as an appropriate response if one experienced impaired health. However continued heavy drinking was also presented as normal behaviour for someone experiencing relative wellbeing in later life, or if ill health was construed as unrelated to alcohol consumption. Older people displayed scepticism about health advice on alcohol when avoiding stigmatised identity as a drinker. Drinking patterns did not appear to be strongly defined by gender, although some gendered expectations of drinking were described. Identities offer a useful theoretical concept to explain the rises in heavy drinking among older populations, and can inform preventive approaches to tackle this. Interventions should engage and foster positive identities to sustain healthier drinking and encourage at the community level the identification of heavy drinking as neither healthy nor synonymous with dependence. Future research should test and assess such approaches.  相似文献

This article explores Arab American "invisibility" as a central theme in the historical narrative of Arab immigrants and their descendants in North America. "Invisibility" is primarily addressed in terms of Arab Americans' paradoxical positioning within the US racial/ethnic classification system. The article argues that four central paradoxes shape Arab American identity. The first paradox is that Arab Americans are a complex, diverse community, but are represented as a monolith in popular North American media images. The second paradox is that Arab Americans are simultaneously racialized as whites and as non-whites. The third paradox is that Arab Americans are racialized according to religion (Islam) rather than biology (phenotype). The fourth paradox involves the intersection between religious forms of identity that Arab immigrants bring to the US and racial forms of identity that structure US society. Overall, the article claims that each paradox of Arab American identity reinforces the difficulties associated in classifying this population.  相似文献

An autochthonous case of epididymal histoplasmosis masquerading as tuberculosis in a 55-year-old male patient is reported from India. It was diagnosed by culture ofHistoplasma capsulatum from semen and by demonstration of the fungus upon re-examination of epididymal biopsy sections previously misinterpreted as tuberculous granuloma. The patient's main complaints were painful epididymal swelling, occasional fever and cough. He was treated successfully by excision of epididymis and vas deferens combined with amphotericin B therapy. This is believed to be the first case of epididymal histoplasmosis to be reported outside the American continent and the fourth of its type reported in the English literature. The case is also noteworthy in thatH. capsulatum was isolated for the first time from semen, and it underlines the importance of mycological culture of semen specimens for diagnosis of genitourinary infections of obscure etiology.Presented at the XII Congress of the International Society for Human and Animal Mycology, Adelaide, Australia, March 13–18, 1994.  相似文献

A study has been made of the probabilities of marriage of females and males aged 15-49 (either as a whole or in 5-year age groups) in two Outer Hebridean islands, Harris and Barra. The results were compared with ages of marriage and with the frequencies of permanent celibacy. The marriages took place between 1861 and 1990. Median ages of marriage rose to maxima in the 1930s and 1940s, then fell steeply, levelling out latterly. Permanent celibacy was consistently high among females, but rose from much lower levels in males to maxima in the 1970s and 1980s. It is concluded that in these populations age at marriage and the extent of permanent celibacy are largely independent of one another. In both islands the overall probabilities of females marrying fell until the 1920s, and then rose. The last decades showed stability (Barra) and a fall (Harris). Males showed only slight falls to about 1910; data were absent for between 1911 and 1960, but subsequently there was little rise in probability. These overall changes seemed to be associated with reciprocal variations in probabilities in the younger and older age groups. Declining overall probabilities were associated with declines in younger and increases in older age-group probabilities, and vice versa. Non-parametric correlations between median ages of marriage and probability of marriage were negative and generally significant for the 15-19 age group. Among the older age groups coefficients were generally positive. There was some evidence of an association between probability of marriage and sex ratio in any group of potential mates. The effect appeared more marked among 15- to 19-year-old females. Local factors which might explain at least part of the decline in nuptiality for the greater part of the period under study include the decline in the fishing industry and the 'land hunger' which existed until the late 1920s. This decline is interpreted as a 'Malthusian' response to economic and social conditions, but it coexisted with a 'neo-Malthusian' strategy, in the shape of declining marital fertility. The 'Malthusian' strategy seems to have been largely abandoned around the 1950s, but it may have reappeared during the 1980s.  相似文献
