Abstract Background Although laparoscopic hepatectomy (LH) is associated with improved short-term outcomes compared to open (OH), it unknown whether frail patients also benefit from LH. The aim of this study was evaluate the impact frailty on postoperative after LH and OH. Methods Consecutive who underwent OH between January 2011 December 2018 were identified a prospective database. Frailty ass...

Abstract Meckel’s diverticulum (MD) is the most common congenital abnormality of gastrointestinal tract resulted from incomplete closure omphalomesenteric tube between 5th-7th intrauterine week. The incidence MD reported to be around 2% in general population. generally asymptomatic during life and symptoms are observed 1% patients. rarely found within hernial sac which known as Littre hernia (L...

LH* generalizes Linear Hsshing to parallel or distributed RAM and disk files. An LH* file can be created from objects provided by any number of distributed and autonomous clients. It can grow gracefully, one bucket at a time, to virtually any number of servers. The number of messages per insertion is one in general, and three in the worst case. The number of messages per retrieval is two in gen...

Patient A was a 30-year-old white woman with a longstanding history of primary amenorrhea and infertility. By age 18 the patient had neither menstruated nor demonstrated evidence of normal breast development. At that time she was given oral contraceptives for four cycles and responded with normal vaginal bleeding. Laboratory evaluation at age 18 demonstrated a serum FSH (follicle-stimulating ho...

Immunization of adult male rabbits with a synthetic luteinizing hormone-receptor peptide (LH-RP; representing amino-acids 21-41 of the extracellular domain of the rat LH receptor) resulted in production of high-titer antibodies capable of interacting with particulate and cell-based LH receptors. The antibody produced was able to inhibit binding of 125I-labeled human chorionic gonadotropin (hCG)...

We have measured the size of the releasable pools of LH and FSH in the pituitary glands of ovariectomized ewes in which the pituitary was isolated surgically from the hypothalamus. The ewes were given GnRH pulses (250 ng) every hour (N = 3) or every 2 h (N = 3) for 1 week and then given a high dose GnRH infusion (0.5 micrograms/min) for 4 h. Blood samples were collected to characterize the LH a...

BACKGROUND High circulating luteinizing hormone (LH) level is a typical biochemical feature of polycystic ovary syndrome (PCOS) whose pathophysiology is still unclear. Certain mutations of LH and LH receptor (LHR) may lead to changes in bioactivity of these hormones. The aim of this study was determine the role of the LH and LHR polymorphisms in the pathogenesis of PCOS using a genetic approach...

Serum LH concentrations were less than 1 ng/ml immediately prior to castration of four 5-month-old Holstein bulls. A significant increase occurred 7 hr post-castration and serum LH remained elevated thereafter, interspersed with non-rhythmic episodic fluctuations of this gonadotropin. Single injections of testosterone or dihydrotestosterone, given iv or im, did not depress post-castration serum...

Although it is well established that the secretory activity of the corpus luteum absolutely depends on the presence of pituitary-derived luteinizing hormone (LH), it is unknown why the life span of the corpus luteum is extended during early pregnancy by the placental production of chorionic gonadotropin (CG) but regresses in the presence of LH despite the fact that CG and LH have similar action...

Gonadotropin-releasing hormone (GnRH) stimulated the formation of two major metabolites of the 5-lipoxygenase pathway, leukotriene (LT) B4 and LTC4, as well as luteinizing hormone (LH) release in primary cultures of rat anterior pituitary cells. Several lines of evidence suggested the presence of a GnRH-dependent pituitary endocrine system in which LTs act as second messengers for LH release: (...
