A comparison of clomiphene citrate and human menopausal gonadotropin for use in conjunction with intrauterine insemination.

Objective: To compare the outcome of superovulation using clomiphene citrate (CC) versus hMG in conjunction with IUI.

Design: Sequentially assigned, observational study. Couples initially were assigned to receive either CC or hMG for three cycles.

Formation of immunochemical advanced glycosylation end products precedes and correlates with early manifestations of renal and retinal disease in diabetes.

Elevated levels of advanced glycosylation end products (AGEs) have been found in multiple tissues in association with diabetic vascular complications and during the microalbuminuric phase of diabetic nephropathy. In this study, we have used an AGE-specific enzyme-linked immunosorbent assay (ELISA) to measure skin AGEs to determine whether elevated levels can be detected before the onset of overt microangiopathy. Subjects with type I diabetes (n = 48) were graded for the degree of nephropathy (normal [23], microalbuminuria [12], or macroalbuminuria [12]) and retinopathy (none [13], background [20], or proliferative [15]).

Anabolic-androgenic steroid and adrenal steroid effects on hippocampal plasticity.

Anabolic-androgenic steroids (AAS) are synthetic androgen-like compounds which are taken in high doses by athletes with the intention of enhancing muscular appearance, strength and/or athletic performance. Recent research indicates that high doses of AAS may influence the functions of the hippocampus. This evidence led us to explore the extent to which chronic AAS treatments influence spatial memory and the integrity of the hippocampus in the rat.

The effect of cigarette smoking on adrenal cortical hormones.

We assessed the association between cigarette smoking and basal levels of adrenal cortical hormones in 11 postmenopausal smokers and 11 postmenopausal nonsmokers and measured the acute adrenal effects of cigarettes in the smokers. After an overnight food, alcohol and tobacco fast, participants smoked or sham-smoked every hr for 8 hr and provided serum samples for hormone assay before and after every other cigarette/sham, as well as before and after a corticotropin stimulation test. The postmenopausal smokers had substantially higher basal levels of androstenedione (4.
