Does Gonadotropin-Releasing Hormone Agonist Administration Before Assisted Reproduction Techniques Improve Pregnancy Rates in Women With Endometriosis?

Importance: Axial downregulation with a 3- to 6-month administration of gonadotropin-releasing hormone agonists (GnRH-a) prior to assisted reproduction techniques has been proposed in order to improve clinical pregnancy rates in women with endometriosis. Although reduced inflammation, improved oocyte quality, and restored endometrial receptivity have been postulated, further investigation of their actual benefit and mechanism of action is considered essential. In that direction, well-designed clinical trials regarding the role of GnRH-a in IVF are necessary.

The effect of GnRH-a on the angiogenesis of endometriosis.

Purpose: Neoangiogenesis is necessary for adhesion and invasiveness of endometriotic lesions in women affected by endometriosis. Vascular endothelial growth factor (VEGF) is one of the main components of angiogenesis and is part of the major pathway tissue factor (TF)-protease activated receptor-2 (PAR-2)-VEGF that leads to neoangiogenesis. Specificity protein 1 (SP1) is a transcriptional factor that has recently been studied for its crucial role in angiogenesis via a specific pathway.

Severe CMV pneumonitis and the resulting ARDS in a 28-year-old pregnant woman: a case report.

Background: Cytomegalovirus (CMV) is a common virus. In pregnant women, CMV infection is usually mildly symptomatic or asymptomatic but can lead to fetal infection. Here we present a rare case of severe CMV pneumonitis and acute respiratory distress syndrome in a healthy immunocompetent pregnant woman.

Wnt4, Wnt6 and β-catenin expression in human placental tissue - is there a link with first trimester miscarriage? Results from a pilot study.

Background: Demystifying the events around early pregnancy is challenging. A wide network of mediators and signaling cascades orchestrate the processes of implantation and trophoblast proliferation. Dysregulation of these pathways could be implicated in early pregnancy loss.

Structure-activity relationships of 111In- and 99mTc-labeled quinolin-4-one peptidomimetics as ligands for the vitronectin receptor: potential tumor imaging agents.

The integrin receptor alpha(v)beta(3) is overexpressed on the endothelial cells of growing tumors and on some tumor cells themselves. Radiolabeled alpha(v)beta(3) antagonists have demonstrated potential application as tumor imaging agents and as radiotherapeutic agents. This report describes the total synthesis of eight new HYNIC and DOTA conjugates of receptor alpha(v)beta(3) antagonists belonging to the quinolin-4-one class of peptidomimetics, and their radiolabeling with (99m)Tc (for HYNIC) and (111)In (for DOTA).

Parotid mass due to cat scratch disease.

Cat scratch disease (CSD), due to Bartonella henselae, is a self-limited chronic lymphadenopathy. A previously healthy 22-year-old woman presented with a palpable painful swelling in the right submandibular region accompanied by enlarged cervical lymph nodes. A diagnosis of B.

Cytomegalovirus enteritis in an immunocompetent host.

A 60-year-old healthy woman presented with fever, abdominal pain and bloody diarrhea. After initial conservative therapy, enterectomy was performed because of perforation of the jejunum. Histological analysis and high titer of anti-CMV IgM confirmed the diagnosis.

The influence of 5-year therapy with tibolone on the lipid profile in postmenopausal women with mild hypercholesterolemia.

Our objective was to investigate the effects of 5-year therapy with tibolone on the lipid profile in postmenopausal women with mild hypercholesterolemia (total cholesterol, 241 +/- 7 mg/dl; LDL cholesterol, 153 +/- 9 mg/dl). Eighty-two patients were divided into two groups. Group A (53 women) received 2.

Design, synthesis, and evaluation of radiolabeled integrin alpha v beta 3 receptor antagonists for tumor imaging and radiotherapy.

The goal of this research is the development of tumor imaging and radiotherapeutic agents based on targeting of the integrin alpha(v)beta(3) (vitronectin receptor). Macrocyclic chelator DOTA has been conjugated to peptidomimetic vitronectin receptor antagonist SH066 to give TA138. TA138 and (89)Y-TA138 retain antagonist properties and high affinity for integrin alpha(v)beta(3) (IC(50) = 12 and 18 nM, respectively), and good selectivity versus integrin alpha(IIb)beta(3) (IC(50) > 10,000 nM).

Orlistat use in overweight women with mild hypercholesterolemia.

In the present study, we investigated the effects of a 6-month treatment with orlistat on body weight and lipid profile in 27 overweight women (mean body mass index [BMI]: 27.5 kg/m2; median age: 38.4 years) with mild hypercholesterolemia (total cholesterol: 225 mg/dl; low-density lipoprotein cholesterol [LDL-C]: 162 mg/dl).
