BACKGROUND: The consumption of significant amounts of alcohol (ethanol, EtOH) may markedly increase serum triglyceride levels. This study describes a significant increase in fasting serum triglyceride (TG) levels in adult male rats whose mothers consumed EtOH. The hypertriglyceridemia occurred although the offspring never directly consumed EtOH and had consumed only rat chow for the preceding 14 months. Furthermore, both male and female adult offspring had an additional, significant increase in TG levels if their mothers consumed EtOH and experienced stress (restraint) during the pregnancy. METHODS: Harlan-derived Sprague Dawley female rats were dosed during pregnancy with EtOH via a liquid diet, and their offspring were compared with offspring of mothers who were either fed ad libitum or pair-fed the liquid diet without EtOH. At birth, the offspring of EtOH mothers exhibited no visible abnormalities except reduced weight, and all offspring were surrogate fostered within 48 hr of birth to mothers who had consumed commercial rat chow throughout their pregnancy. After weaning, all offspring consumed only commercial rat chow, and they were examined over the next 14 months for changes in triglyceride homeostasis as a function of maternal alcohol intake. RESULTS: Adult male offspring of mothers that consumed EtOH during their pregnancy had significant increases in fasting serum triglycerides associated with an increase in the very low density lipoprotein serum fraction. Acute administration of insulin to the offspring of all maternal dietary groups resulted in a rapid clearing of the serum triglycerides, and there were no differences in basal or heparin-releasable lipoprotein lipase activity between any of the progeny. Castration of the male offspring of EtOH-treated mothers prevented the development of elevated TG levels. Administration of testosterone to littermate female offspring increased circulating TG levels compared with testosterone-treated offspring of pair-fed mothers. EtOH-consuming mothers who also underwent five periods of restraint-induced stress (approximately 10 min each session) produced offspring whose fasting serum TG levels were higher than those whose mothers consumed EtOH but experienced no restraint or who experienced restraint but no EtOH. Maternal stress significantly reduced lipoprotein lipase activity in some offspring treatment groups, but the changes did not correspond to changes in the serum TG levels of the offspring. That is, maternal restraint-induced stress was associated with a loss of heparin-releasable lipoprotein lipase activity by male progeny from pair-fed and EtOH-fed mothers and the female offspring of ad libitum-fed and EtOH-fed mothers. CONCLUSIONS: Although serum triglycerides increased with age in all offspring, the increase was much more pronounced in the progeny of mothers who consumed EtOH during their pregnancy. The hypertriglyceridemia was significantly more pronounced in the male offspring and in female offspring treated with testosterone. Castration of male offspring inhibited the hypertriglyceridemia development, which suggests that male sex hormones may play a role in the development of this condition. Maternal EtOH consumption coupled with maternal restraint-induced stress significantly increased the level of hypertriglyceridemia in both male and female offspring compared with offspring whose mothers experienced restraint but no EtOH or EtOH with no restraint. If this study models the human condition, the results could represent an unrecognized risk factor in a number of adult disease states hypothesized to be associated with hypertriglyceridemia, such as cardiovascular disease, hypertension, and diabetes.

OBJECTIVES: The present study was designed to determine whether clinical and endocrine characteristics assessed on initial screening of normogonadotropic oligo/amenorrhoeic infertile patients could predict ovulation and then conception and successful live birth or miscarriage. STUDY DESIGN: Retrospective cohort study SETTING: Outpatient clinic. POPULATION: Eighty-two consecutive women receiving clomiphene citrate (CC) therapy from 1993 to 1998. RESULTS: A cumulative conception rate of 67% was reached after six or more CC-induced cycles. Patients with failure of ovulation after a full course of CC had more severe oligomenorrhoea (p < 0.001) and greater BMI (p < 0.05) at initial screening. There was no relationship with levels of LH or androgens. In contrast, among women who ovulated in response to CC, conception was associated with less frequent periods, and higher basal levels of LH, free testosterone and androstenedione. Conceptions with subsequent miscarriage were associated with intermediate levels of LH and numbers of spontaneous periods between non-conception and live births. CONCLUSIONS: These observations are consistent with the hypothesis that failure of ovulation after CC is related to different factors (overweight and severe oligomenorrhoea) from those that predispose to non-conception (low basal LH and androgen levels and mild oligomenorrhoea).

In vitro effects of some steroidal hormones on the replication of avian pneumovirus.
Al-Afaleq AI, Jones RC, Homeida AM, Savage CE.
Department of Microbiology and Parasitology, College of Veterinary Medicine and Animal Resources, King Faisal University, Al Ahsa, Saudi Arabia.
The effects of testosterone, oestradiol, progesterone and cortisone on the in vitro replication of avian pneumovirus in tracheal organ cultures (TOC) were investigated. Samples of cell-associated and cell-free virus from TOC, grown in medium containing these hormones, were taken at selected intervals. Progesterone and cortisone caused a slight increase in cell-associated virus. Testosterone and oestradiol caused a slight delay and decrease in virus replication when compared with the controls. All groups shared the same time interval to reach peak cell-free virus titre, 96 h post inoculation. In comparison with the controls, only a small drop (0.25-0.50 log10) in the peak of virus titre was observed in the hormone treated groups.

BACKGROUND: Modulation of the expression of retinoic acid receptors (RAR) alpha and gamma in adult rat prostate by testosterone (T) suggests that RAR signaling events might mediate some of the androgen effects on prostate cells. METHOD: In this study, we examined the interactions between T and retinoic acid (RA) in cell growth of human prostate carcinoma cells, LNCaP, and their relationship with the expression of RAR and epidermal growth factor receptor (EGF-R). RESULTS: Both T and RA, when administered alone, stimulated 3H-thymidine incorporation in LNCaP cells in a dose-dependent manner; the effect of each agent was reciprocally attenuated by the other agent. Testosterone treatment of LNCaP cells also resulted in dose dependent, biphasic increases in RAR alpha and gamma mRNAs; increases paralleled that of 3H-thymidine incorporation and were attenuated by the presence of 100 nM RA. These results suggest a link between RAR signaling and the effect of T on LNCaP cell growth. Gel electrophoretic mobility shift assays revealed the presence of putative androgen responsive element (ARE) in the promoter region of RAR alpha gene, suggesting that a direct AR-DNA interaction might mediate the effects of T on RAR alpha gene. Furthermore, treatment of LNCaP cells with 20 nM T resulted in an increase in EGF-R. In contrast, EGF-R was suppressed by 100 nM RA that also suppressed the effect of T. CONCLUSIONS: Current results demonstrate interactions between T and RA in the expression of RARs and cell growth in LNCaP cells. The presence of putative ARE in the promoter of the RAR alpha gene suggests that AR-DNA interaction might mediate the effects of T on RAR alpha gene. The opposite effects of T and RA on the expression of RAR and EGF-R suggest that signal events of these receptors might be involved in the interaction between T and RA in the control of LNCaP cell growth.

Like developmental biology of any part of our body, hair growth is a complicated process. Hence the homework for
modern science to yet unravel the process and mechanism to a completion. There exist a number of traditional and alternative therapeutic methods that include drugs, surgery, suppelements, and even snake oils that have been developed and used for those who lose hair.
No understanding, and there is no solution. Of course, none of these approaches are perfect for all hair loss problems, especially due to the heterogeneity of the causes underlying hair losses. Most of chemical drugs and hair transplantation surgeries are accompanied by undesirable side effects.
DHEA is a natural hormone, and it is produced in our body by the adrenal glands.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
Our bodies produce decreasing amount of DHEA as we get older.
various health benefits: To deter aging,
improve sexual function/erectile dysfunction, treat cognitive decline, enhance athletic performance,
facilitate weight loss, improve strength, prevent osteoporosis, enhance immunomodulation for rheumatic conditions,
and treat depression.
