Possibility of hidden damages with temporary uterine artery occlusion device Sir, I read the article of Vilos et al. (2006) with interest, but I need to give some opinions about the use of this Doppler-guided transvaginal clamp. First, it is possible that the pelvic ureter will be occluded (Al-Awadi et al., 2005) when the transvagi-nal clamp closes. In this case, the ureter could be damaged, an...

Tamoxifen is a widely used in anti-oestrogen treatment of breast cancer. Previous reports showed that tamoxifen is associated with proliferative endometrial lesions. We herein reported an unusual case of concurrent hyperplastic lesions in the uterine cavity and right ovary in a 45-year-old woman with tamoxifen therapy. Regular vaginal ultrasonography showed the progressive endometrial thickenin...

Introduction: Polycystic ovary syndrome is a complex disorder characterized by elevated androgens, chronic anovulation, and polycystic picture on ultrasound it is one of the most common hormonal disorders, affecting 5%–10% of women of reproductive age. Despite many diagnostic criteria, controversies still exist in definition, evaluation and management of PCOS. Aims and Objective: To investigate...

The ovary receives a finite pool of follicles during fetal life. Atresia remains the major form of follicular expenditure at all stages since development of ovary. The follicular reserve, however, declines at an exponential rate leading to accelerated rate of decay during the years preceding menopause. We examined if diminished follicle reserve that characterizes ovarian aging impacts the attri...

Aromatase CYP19 catalyzes the synthesis of estrogen from androgens in a tissue-specific manner. This enzyme is present in several tissues, including gonads, brain and fatty tissue. More recently, its presence has been described in vessels. Here, we describe the expression of aromatase in human uterine artery and compare its expression with that found in arteries of estrogen-dependent uterine le...

pseudomonas aeruginosa ef2, atcc 9027 and atcc 19660 were grown in a continuous culture under tween 80 (polyoxyethylene sorbitan monooleate) limitation and optimum conditions (ph 6.5, 37°c at dilution rate of 0.05/h). culture supernatants were carefully removed and stored at -20°c. to purify the lipases, the culture supernatant was reduced in volume to approximately 10 ml by an ultrafiltration ...

Acetone powder extracts prepared from cultured pig aortic smooth muscle cells and the culture medium from these cells (particularly when incubated with heparin) were shown to contain a lipolytic enzyme which was identified as lipoprotein lipase by the following criteria: 1) stimulation by apolipoprotein C-II; 2) an optimal activity at approximately pH 8.0; 3) inhibition by NaCl, and 4) binding ...

Antigenic components were solubilized from a participate fraction of mouse lymphosarcoma 6C3HED at pH 9.0-9.5. Protein, lipid, and carbohydrate were present. Three measures of antigenicity were employed. Mouse cytotoxicity tests re vealed that the tumor fraction adsorbed a greater amount of rabbit antitumor antibody than did similar fractions of normal C3H mouse lymphoid tissues. In Schultz-Dal...

In recent publications (l-3), the clearing factor of postheparin plasma has been identified with a lipoprotein lipase obtained from rat, rabbit, and calf heart and rat and rabbit adipose tissue. This enzyme catalyzes the hydrolysis of the triglyceride moiety of chylomicrons and low density @-lipoproteins. The hydrolysis of simple triglyceride emulsions is also catalyzed by lipoprotein lipase bu...
