Kisspeptin (KP) is a group of hypothalamic neuropeptides encoded by KISS-1 gene. KP-54, a 54-amino-acid peptide, helps regulate the hypothalamic-pituitary-ovarian axis and plays a potential role in implantation. C57BL/6 J female mice were superovulated via intraperitoneal injection of 5 International Units (IU) pregnant mare serum gonadotrophin (day 1).

However, recent studies reported a development of M-resistance, which prompted us to look for alternatives. Here, we investigate the potency of a mixture of M with spinetoram (Sp) on M-resistant insects.

This Study Aims: To re-assess the efficacy and safety of PRP in the management of chronic leg ulcers due to venous factors.
Although the toxicity/biocompatibility of hydroxyapatite nanoparticles (HAPNPs), a prospective nano-biomaterial, is extensively studied, its interaction on the reproductive system following exposure is less exploited. In the present study, male rats were exposed to HAPNPs (300 mg/kg BW) to determine its possible reproductive toxicity. Also, the protective effects of chitosan (CSNPs, 280 mg/kg BW) and/or curcumin (CurNPs, 15 mg/kg BW) nanoparticles against HAPNPs-induced reproductive toxicity were studied.

However, there are outstanding findings from various studies that question whether these NPs are safe when they are used in the human body. Therefore, a more in-depth toxicity assessment should be carried out to give a clear answer regarding the fate of these particles.

Mechanisms of tissue dissemination in endometriosis may be similar to those involved in tumor metastasis. We hypothesize that dysregulation of kisspeptin (KISS1), a metastasis suppressor in endometrial carcinoma, may contribute to the pathogenesis of endometriosis.

However, the current toxicity data for HAP-NPs regarding human health are limited, and only a few results from basic studies have been published. Therefore, the present study was designed to investigate the beneficial role of chitosan nanoparticles (CsNPs) and curcumin nanoparticles (CurNPs) in alleviating nephrotoxicity induced by HAP-NPs in male rats.

Venous congestion is the most commonly encountered problem after replantation due to the difficulty of venous anastomosis in traumatic injuries. Heparin, among other drugs, is commonly used to facilitate venous drainage and prevent thrombosis.

Background: Facial burns represent between one-fourth and one-third of all burns. The long-term sequelae of periorbital burns include significant ectropion and lagophthalmos as a result of secondary burn contractures in the lower and upper eyelids, in addition to complete or incomplete alopecia of the eyebrows.
Methods: A retrospective study of 14 reconstructive procedures for 12 postburn faces was conducted with all procedures performed since 2010 at the Department of Plastic Surgery, Al-Hussein University Hospital, and at the Craniofacial Unit, Nasser Institute Hospital.

Purpose: To propose a new classification of diabetic cystoid macular edema (CME) based on optical coherence tomography (OCT) findings and cover all new important findings.
Patients And Methods: A retrospective study was carried out in the El-Minia Investigation Eye Center between January 2012 and November 2012. It included 104 eyes of 86 patients, aged between 50 and 71 years, all with type II diabetes mellitus of duration from 5 to 20 years.
Unlabelled: The coming decade will bring new and even more complex advances that will transform oral and maxillofacial surgery practice if the specialty is capable of transferring the advances of basic science into clinical practice. Such advances include those in tissue engineering and nanotechnology. Three groups of eight animals (rats), each was evaluated by grouting bone graft substitutes into 3 mm holes that were made into the anteromedialtibialmetaphyses of rats.

Methods: Married women attending the outpatient clinic of Sohag University Hospital between February 2008 and March 2009 were recruited. Through direct interviews, each woman completed a questionnaire that included questions on sexual dysfunction.
Objective: To evaluate psychiatric morbidity in Egyptian women before and after hysterectomy for benign indications.
Method: A 2-year prospective observational study at Sohag University Hospital, Egypt, in which 96 women scheduled for hysterectomy were assessed for psychiatric comorbidity before and after the operation using the General Health Questionnaire (GHQ-28), Beck Depression Inventory, and Hamilton Anxiety Scale.
Results: Of these, 35 (36.
