'Steroid hormones are essential for the growth, differentiation and function of many tissues in both animaIs and humans. It has been established by animal experimentation that modification of the hormonal environment by surgical removal of endocrine glands, by pregnancy or by exogenous administration of steroids can increase or decrease the spontaneous occurrence of tumours or the induction of ...

In this second overview of the current management of infertility we discuss anovulatory infertility and polycystic ovary syndrome. This syndrome (formerly known as Stein-Leventhal syndrome) is the most common hormonal disturbance in women—around one fifth of women in the United Kingdom are affected. It is also themost common reason for women not to ovulate, and the combination of being overweig...

In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

Olfaction is an important determinant of attractiveness, possibly even more so than vision when judgments are made by women. However, research that directly compares these cues using actual stimuli (e.g., t-shirt odors) is lacking. In this study, 44 women rated the attractiveness of t-shirt odors and facial photographs of 21 men either independently (i.e., first rated t-shirts, then rated photo...
