Adipose tissue accumulation by trapping vitamin D and reducing its level may cause serious side effects. The purpose of this study is to determine the effects of vitamin D supplementation on dehydroepiandrosterone (DHEA), paraoxonase 1 (PON 1), insulin, free fatty acid (FFA), apolipoprotein-AI (Apo-AI) and apolipoprotein B (Apo-B) concentration in obese and overweight participants under low-calorie diet (LCD) program.

Healthy overweight and obese individuals (n = 70) with vitamin D deficiency were randomly assigned into 2 groups to receive either vitamin D supplements (an oral 2,000 IU vitamin D supplement) or placebo for 8 weeks.

All the participants were given an LCD program during the intervention. Vitamin D supplementation led to a significant increase in the levels of 25(OH)D (vitamin D vs placebo groups: 36.6 ± 9.8 vs 19.9 ± 3.5 ng/mL, p < 0.001), PON 1 levels (vitamin D vs placebo groups: 80 ± 25 vs 58 ± 23.2 ng/mL, p = 0.001), DHEA concentration (vitamin D vs placebo groups: 2.3 ± 0.7 vs 1.5 ± 0.6 ng/mL, p < 0.001) and Apo-AI levels (vitamin D vs placebo groups 3.7 ± 0.5 vs 3 ± 0.5 mg/dL, p < 0.001). Besides, intake of vitamin D supplements led to a significant decrease in FFA (vitamin D vs placebo groups: 3.1 ± 0.75 vs 3.5 ± 0.5 ng/mL, p = 0.001). After adjusting the analyses based on baseline levels, age and baseline body mass index measures, significant changes were observed in the insulin levels (0.03 ± 0.06 vs −1.7 ± 0.6 µIU/ml, p = 0.04). But the authors did not find any significant difference in the concentration of Apo-B between groups (vitamin D vs placebo groups: 71.5 ± 35.5 vs 66.6 ± 28.5 mg/dL, p = 0.05).

Overall vitamin D supplementation for eight weeks among vitamin D-deficient obese and overweight participants had beneficial effects on serum DHEA PON 1 FFA insulin and Apo- AI while it did not affect the Apo-B concentration.

The importance of anabolism and regeneration is related to lack or loss of control. This chapter discusses the psychophysiological basis for such relationships. In the threat of lost control, energy mobilisation is activated and regeneration is inhibited – since regeneration (repairing) has low priority in emergency situations. This pattern can be traced on several psychophysiological levels, from the brain to most of the cells in the body. Such a mechanism explains why the body becomes vulnerable and increasingly sensitive to load when threat of lost control is excessive and long lasting. In several empirical examples, various indicators of anabolism and regeneration have paralleled improvement versus deterioration in psychosocial conditions, in particular lack or loss of control. In these studies, indicators of anabolism and regeneration (such as concentration of sex hormones with anabolic and regenerative functions in blood and saliva) have been followed in subjects going through deteriorating versus improving life conditions. The demand-support model is used as a theoretical basis for the discussion.

This paper aims to design to evaluate the protective effect of vitamin E to ameliorate the disturbances in testosterone pathway and sperm quality of male rats induced by the glycosides vicine (V) and convicine (C) of Vicia faba.

Forty male albino rats were divided into five equal groups; control, paraffin oil, V (400 mg/kg) C (150 mg/kg)-treated group, vitamin E (100 mg/kg) + VC-treated group, and vitamin E (200 mg/kg) + VC-treated groups which injected intraperioneally (IP) with 0.5-ml saline, 0.5-ml paraffin oil,V (400 mg/kg) and C (150 mg/kg) of Vicia faba, vitamin E (100 mg/kg) + VC-treated groups, and Vitamin E(200 mg/kg) + VC-treated groups, respectively. Blood and testicular tissue were obtained after one month of the study. The male genital organs were calculated. Testosterone (Ts), luteinizing hormone (LH), follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEA-SO4), sex hormone binding globulin (SHBG),?-glutamyl transpeptidase (?-GT), glucose-6-phosphate dehydrogenase (G6PD), 3ß-hydroxysteroid dehydrogenase (3ßHSD), lactate dehydrogenase (LDH), spermatozoa concentration, percent of mortality and abnormal sperms were evaluated.

The VC-treated group showed significant decrease (p < 0.01) in Ts, DHEA-SO4, G6PD, spermatozoa number and mortality percent, as well as, the male genital organs (testes, epidydemis, seminal vesicle, prostate and vasa deferentia) while significant increase (p < 0.01) was found in LH, FSH, SHBG, LDH, ?-GT, sperms monoclonal Ki-67, and abnormal spermatocytes levels compared with control group. Vitamin E co-injection with VC-treated group returned all these parameters to the normal values. The higher dose of vitamin E (200 mg/kg) was more effect than the lower dose (100 mg/kg).

Vicia faba contains V and C glycosides. The V and C glycosides in Vicia faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The V and C glycosides induced disturbances in testosterone pathway and sperm quality of male rats and vitamin E ameliorates these disturbances.

We are in the midst of a broad societal change in which women’s sexual problems are becoming increasingly medicalized, characterized as treatable medical conditions and defined and understood as a largely physiologically based disease, called “female sexual dysfunction” (FSD). When a condition is medicalized, a medical framework is used to understand it, and medical interventions are used to treat it. As part of this process, then, over the last several years, researchers and pharmaceutical companies have turned attention to developing medical treatments for FSD. As this medicalization continues to unfold with potentially important impacts, it is crucial that we understand the forces working to shape it.

Schizophrenia is a serious psychiatric disorder characterized by positive symptoms, negative symptoms and neurocognitive deficits. The aim of this study was to estimate relationships between wellness, yoga and quality of life in patients affected by schizophrenia spectrum disorders. Participants were 30 patients with a diagnosis of schizophrenia in care at the Rehabilitative Psychiatry and Research Villa Chiara Clinic in Mascalucia (Catania, Italy), after that randomly assigned to two groups. The first group followed the experimental treatment with sets of yoga exercises conducted by a yoga trainer and a psychiatrist or a clinical psychologist expert in yoga, while a second control group was treated with usual care. The results revealed a significant difference, before and after treatment, between the experimental group and the control group in quality of life.

The ageing process is often discussed as though it is unique to humans. However, it can be observed throughout the plant and animal kingdoms. In every species in which it occurs, the ageing process has common traits. It is a progressive, intrinsic, cumulative and deleterious process that eventually gives rise to physiological frailty, morbidity and death. Historically, biogerontology had a slow start but the last 10 years have seen exceptional progress in understanding both why and how ageing changes occur. As a result of this new knowledge, interventions that could produce longer, healthier human lives are close to becoming clinical realities. Unfortunately, the speed and scale of these advances is not well understood outside the relatively small community of biological gerontologists. This article reviews some of these advances for a non‐specialist audience, speculates on their potential impact and identifies current barriers to future progress.

Depression is one of the most overlooked psychiatric disorders among middle-aged and elderly men. Saffron (Crocus sativus L.) stigmas are a favorite and common spice that is used as an antidepressant, an anti-inflammatory and a sexual stimulant. This systematic review aimed to provide a comprehensive survey of the effects of saffron on depression in middle-aged and elderly men.

The authors searched Web of Science, PubMed, ProQuest, Cochrane, Science Direct, Scopus and Google Scholar databases to gather any relevant studies published from 1980 to September 2022. This review included studies that examined the relationship between depression and testosterone concentration (four studies) or saffron’s effects on testosterone and depression (six studies).

Observational research showed an association between testosterone and depression in middle-aged and elderly men. Furthermore, animal studies have found that saffron increased testosterone levels and decreased depression in males. There is evidence that testosterone may contribute to the mood. Besides its antioxidant and anti-inflammatory properties, this study proposed scientific mechanisms that saffron may also play a protective role against depression through its influence on testosterone, in middle-aged and elderly men. The general use of saffron at high doses or for prolonged periods may cause side effects; therefore, it is important to consult a health-care professional before the recommended dosage and duration of saffron supplementation, especially if a person has any underlying health conditions or is taking medications.

This study provides researchers with an additional perspective for conducting clinical trials on the use of saffron to enhance the mood of elderly men with testosterone deficiency.

In this paper we present preliminary findings from a study of the social, ethical and cultural aspects of ageing science and medicine. The paper draws on a collaborative, ongoing project between life scientists and sociologists, funded by the Economic and Social Research Council's (ESRC) New Dynamics of Ageing Programme1 and the ESRC Centre for the Economic and Social Aspects of Genomics2. The sociological element of this project involves participant observation and interviews with expert scientists who specialise in ageing and age‐related diseases, both in the UK and the US, as well as interviews with sceptics of ageing science and medicine. There has been much critique of how ageing science is anti‐ageing, reinforcing the ageism prevalent in Western culture. Our specific objective in this paper is to suggest how biogerontology can contribute to the social inclusion of older people, particularly in relation to health care. We discuss how agesim is endemic to some aspects of health care, and go on to show how the ways that biogerontology is reconceptualising what it is to age, and to be old, can help reinclude ageing and the aged in health‐care education, policy and practice.
