Antimicrobial susceptibility testing.
This review emphasizes the continued efforts toward standardization of methods for dilution and diffusion testing, particularly in the area of variation in medium performance, methods for detection of ampicillin resistant Haemophilus influenzae, and attempts to develop rapid automated systems for susceptibility testing.

This classic gives you a solid grasp of the significance of etiologic agents, the pathogenic processes, epidemiology, and the basis of therapy for infectious diseases. Expand
Ethics in obstetrics and gynecology.

We are now in an era when everything done in medicine is judged in ethical terms, and this is certainly the case for obstetrics and gynecology, which has had more than its share of morally troublingExpand
Phylogenetic distribution of aromatase and other androgen-converting enzymes in the central nervous system.
Comparisons with previously reported comparative studies indicate that the ability to aromatize and otherwise transform androgen substrates is a primitive characteristic of the brain that has been widely conserved phylogenetically. Expand
The microenvironment of the human antral follicle: interrelationships among the steroid levels in antral fluid, the population of granulosa cells, and the status of the oocyte in vivo and in vitro.
It is tentatively suggested that follicles with a potential for further development are those with more than 50‰ of their full complement of granulosa cells for their respective diameters, and high concentrations of 17β-estradiol in their antral fluid. Expand
The formation of estrogens by central neuroendocrine tissues.
Much of what I will discuss here today relates to brain differentiation in rodents. This subject was the interest of two outstanding British scientists, Geoffrey Harris and Peter MacDonald. HarrisExpand
Insulin stimulates androgen accumulation in incubations of ovarian stroma obtained from women with hyperandrogenism.
The studies suggest that human ovarian stroma may be a target tissue for insulin and IGF-I, and that hyperinsulinemia may be an important factor contributing to ovarian hyperandrogenism. Expand
Hyperandrogenism, insulin resistance, and acanthosis nigricans syndrome: a common endocrinopathy with distinct pathophysiologic features.
The relationship between insulin resistance and hyper androgenism may explain the hyperandrogenemia seen in the following disease processes: obesity, acromegaly, lipoatrophic diabetes, leprechaunism, and Kahn types A and B insulin resistance. Expand

While estrogens are the key to pituitary, breast, and endometrial growth and development, this hormone is one of the few examples of an endogenous steroid that has been implicated as a carcinogen or a stimulant for carcinogenesis. Expand
No association between coffee consumption and adverse outcomes of pregnancy.
It is suggested that coffee consumption has a minimal effect, if any, on the outcome of pregnancy and there was no excess of malformations among coffee drinkers. Expand
