  • Tendons are known to have a profound impact on the overall function of the musculoskeletal system in their role as a structural link and force transmitter between muscle and bone. Their unique viscoelastic response under tension allows efficient use and recycling of stored energy during stretch involved in locomotion, modulating joint position control, and providing protection from muscle injuries through reduction of mechanical oscillation and shock.

  • Addressing the health needs of women living with HIV/AIDS presents special challenges, including that of screening for cervical cancer. These women are at increased risk of HPV infection, and thus, of developing cervical cancer, 26, 27 an AIDS-defining condition. 28 While the current document cannot review this topic in detail, studies are available with information on whether there is a need for specific screening guidelines for HIV- positive women.

  • Diethylstilbestrol (DES) acting as an estrogen at the level of the hypothalamus to downregulate hypothalamic luteinizing hormone (LH) production results in decreased elaboration of testosterone by the testicle. For this reason, orchiectomy is equally as effective as moderate-dose DES, inducing responses in 80% of previously untreated patients with prostate cancer but without the prominent cardiovascular side effects of DES, including thrombosis and exacerbation of coronary artery disease.

  • Fourth, our analysis of consultation patterns for the management of specific pregnancy- related conditions suggests pregnant women are making discretionary decisions regarding whom to consult depending on their immediate health concerns. Chiropractors are frequently consulted for back pain and sciatica, massage therapists consulted more commonly for neck pain, and naturopaths and acupuncturists more likely to be consulted for pregnancy-related nausea. Women are consulting with CAM practitioners most commonly for management of pain-related conditions.

  • Gprotein-coupled receptor 30 (GPR30) has previously been described tobe important in steroid-mediatedgrowthand to inhibit cell proliferation. Here we investigated whether the effect of GPR30 on cell growth is dependent on steroid hormone receptors. We stably introduced GPR30 in immortalizednormalmammaryepithelial (HME) cellsusing retroviruses for gene delivery. GPR30 inhibited the growth and proliferation of the cells. They expressed glucocorticoid receptor, but not estrogen or progesterone receptor....

  • Dehydroepiandrosterone (DHEA) has a protective role against epithelial-derived carcinomas; however, the mechanisms remain unknown. We deter-mined the effect of DHEA on cell proliferation, the cell cycle and cell death in three cell lines derived from human uterine cervical cancers infected or not with human papilloma virus (HPV).

  • Contraceptive methods can be divided into two subgroups as hormonal and non-hormonal. Hormonal contraceptives include combined-oral contraceptives, progestin only pills, hormonal implants, progestin releasing intrauterine systems, depomedroxyprogesterone acetate injections, and vaginal rings. Non-hormonal contraceptive methods include male and female condoms, copper intrauterine device, tubal ligation and vasectomy of the companion. Combined oral contraceptives are a widely used and well accepted form of contraception.

  • An intensive weight loss program in Slovenia including behavioral, psychological, cognitive and physical ele- ments has shown promising long-term results on 48 sub- jects [21]. Median weight loss of completers when they left the program was 11.5 kg. At least 5 years later, 13 of them still maintained the reduced weight. It is important to note that only participants who had successfully completed at least 4 months of treatment were included in the analysis.

  • Estrogen acts as a proconvulsant in several animal models of epilepsy, including amygdalal kindling and pentylenetetrazol administration in ovariectomized rats (Hom and Buterbaugh, 1986). Estrogen induces the formation of new excitatory synapses in the CA1 region of the hippocampus; and further, this estrogenic induction involves activation of Nmethyl- Daspartate (NMDA) receptors (McEwen, 2002). Increasing the complexity of hippocampal synaptic density is likely a mechanism for the proconvulsant activity of estrogen.

  • Depression is more common in women than in men and is known to be mediated by serotonin receptor levels [43,63]. Specifically, depression is linked to decreased density of serotonin receptors and decreased efficacy of serotonin in the brain. The increased risk, timing of onset, and effectiveness of treatment of depression in women may be mediated by estrogen's effect on serotonin recep- tors.

  • The current literature documents a wide range of individ- ual effects of both estrogen and serotonin, which have been successfully used to explain both normal and patho- logical processes. E2, for example, initiates the develop- ment of the female reproductive system, influences the deposition of body fat, regulates the production of prolac- tin and other hormones, and increases sodium and water retention [41]. Independent of estrogen, serotonin regu- lates urination, influences the production of cerebrospi- nal fluid, and relaxes vascular smooth muscle [42].

  • A: high-fat diet can increase the risk of many cancers, including endometrial cancer. Because fatty foods are also high-calorie foods, a high-fat diet can lead to obesity, which is also an endometrial cancer risk factor. Some doctors think that fatty foods may have a direct effect on estrogen levels, which can increase risk, too. Exercise protects against endometrial cancer. Studies found that women who exercised more had a lower risk of this cancer, while one study showed that women who spent more time sitting had a higher risk....

  • COMBINED ORAL CONTRACEPTIVES Mechanism of action The combined oral contraceptive (COC) pills currently available in the UK are shown in Table 2. They combine an estrogen (ethinylestradiol (EE) in all cases but one) with one of seven progestogens. Aside from secondary contraceptive effects on the cervical mucus and to impede implantation, COCs primarily prevent ovulation. This makes the method highly effective in ‘perfect’ use (Table 1), but it removes the normal menstrual cyle and replaces it with a cycle that is user-produced and based only on the end-organ, i.e. the endometrium.

  • The choice of a specific oral contraceptive should be predicated on the progestational component, as progestins vary in their suppressive effect on SHBG levels and in their androgenic potential. Ethynodiol diacetate has relatively low androgenic potential, whereas progestins such as norgestrel and levonorgestrel are particularly androgenic, as judged from their attenuation of the estrogen-induced increase in SHBG. Norgestimate exemplifies the newer generation of progestins that are virtually nonandrogenic.

  • Estrogen receptors and serotonin receptors coexist in cells in a wide variety of tissues, and this critical review of the literature suggests that many of E2's effects may be medi- ated by changes in the actions of serotonin (5HT). Serot- onin is usually considered to be a neurotransmitter, but surprisingly, only 1% of serotonin in the human body is found in the CNS [4].
