BACKGROUND Biliopancreatic gallstone disorders (BPD) manifesting during pregnancy are relatively rare. The management of these conditions remains controversial. Although perioperative problems and fetal loss have been reported, recent publications have advocated an early surgical approach. PATIENTS AND METHODS Thirty-two pregnant women underwent operation(More)
Lipoprotein lipase is an enzyme in adipose tissue that hydrolyzes circulating triglycerides and thereby generates the fatty acids used in the synthesis of triglyceride in fat cells. To determine whether the activity and expression of lipoprotein lipase are affected by weight loss, we studied lipoprotein lipase in the adipose tissue of nine very obese(More)
The p53 gene is altered in approximately 50% of human cancers and is considered to be important in the pathogenesis of these malignancies. The p53 protein product regulates the transition from G1 to S phase of the cell cycle and entry to the DNA damage repair pathway. As alterations in this pathway appear to be important in a variety of human cancers,(More)
Few molecular genetic alterations have been identified in endometrial cancers that are associated with poor clinical outcome. Overexpression of HER-2/neu, transforming growth factor alpha, and p53 proteins have all been associated with poor prognosis in women with endometrial cancer. In this study, the level of HER-2/neu gene amplification and expression(More)
Previous studies have demonstrated that in vitro treatment of adipocytes with catecholamines results in a decrease in the activity of the enzyme lipoprotein lipase (LPL). To examine the mechanism of this effect, primary cultures of rat adipocytes were cultured in the presence of various concentrations of epinephrine (10(-9)-10(-5) M). Epinephrine yielded a(More)
Lipoprotein lipase (LPL) is an enzyme found in adipose tissue that is important in the hydrolysis of triglyceride rich lipoproteins, and in the uptake of FFA lipid into the adipocyte. To examine the effects of glucocorticoids on adipose tissue LPL, male Sprague-Dawley rats were injected with dexamethasone (1 mg/kg) every other day for 10 days, followed by(More)
Macrophages are important cells in the pathogenesis of atherosclerosis because of their tendency to accumulate lipid and become transformed into foam cells. Cultured human monocyte-derived macrophages spontaneously secrete lipoprotein lipase (LPL), and LPL has been linked to increased lipid uptake by these cells. Because secretion of various macrophage(More)
Patients with diabetes commonly manifest hypertriglyceridemia along with decreased adipose tissue lipoprotein lipase (LPL) activity, and improved diabetes control tends to reverse these abnormalities. To better understand the mechanism of regulation of LPL in diabetes, 11 diabetic patients (3 type I, 8 type II) were brought under improved glycemic control,(More)
Lipoprotein lipase (LPL) is an important enzyme in lipid metabolism, and adipose LPL activity is increased in rats that are deficient in thyroid hormone. To examine the mechanism of thyroid hormone's effect on LPL, LPL gene expression was assessed in the epididymal fat pads of hypothyroid rats. When compared to control rats, LPL activity, mass, and(More)
