The Role of Peroxisome Proliferator-Activated Receptors in PGF-Induced Luteolysis in the Bovine Corpus Luteum.

The participation of peroxisome proliferator-activated receptors (PPARs) in ovarian function in cattle is still not fully understood. The aim of this in vitro study was to determine: (i) the immunolocalization, mRNA expression and tissue concentration of PPARα, PPARδ and PPARγ in the bovine corpus luteum (CL) ( = 40) throughout the estrous cycle, and (ii) the involvement of PPAR in PGF-induced processes related to luteolysis. CL ( = 9) explants were cultured in the presence of PPAR antagonists (10 M) in combination with or without PGF receptor antagonist (10 M) and PGF (10 M).

The influence of experimentally induced endometritis on the PPAR expression profile in the bovine endometrium.

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors of the nuclear receptor superfamily. The PPARs activity can be modified e.g.

Primary hydatid cyst of the pancreas.

Hydatid cyst of the pancreas is a rare location of this disease. We study the case of a female patient with primary hydatid cyst of the pancreas coming from and endemic area and presenting pain and palpable tumor in epigastrium and right upper abdomen. The patient was studied with ultrasound scanning and CT scan in which it was interpreted as hydatid liver cyst.

[Mannheim index in acute perforated abdomen in patients 65 years].

We present a prospective and protocolizeted study of 98 patients over 65 years, underwent emergency surgery for perforated acute abdomen in the Hospital Nacional de Clínicas during the period from April/2007 to April/2013. The purpose was to determine the morbidity and mortality of this entity in the elderly. Mainly affected were women between 65 and 75 years.

[Retroperitoneal Tumor: Neurofibroma.].

The neurofibroma is a benign tumor that grows from the sheath of the peripheral nerves, which is often localized on superficial tissues, especially in isolated forms. The neurofibromas can be of two types, localized or diffuse, the last one closely related to Von Recklinghausen disease or NF-1. We described a 37 years old male e patient, 37 years without symptoms, and the computed tomography scan (CT), and magnetic resonance imaging showed a tumor in proximity to the right kidney, the psoas muscle, the spine and compressing the cava vein, but cannot be accurately determinate the invasion of these structures.

[Mini-laparoscopy vs. laparoscopy for the gallblader stone treatment. Prospective and comparative study].

Background: Laparoscopic cholecystectomy is considerated as the gold standard for the gallbaldder stones treatment, however, in the international literature the adapted smaller incisions is still an alternative procedure. Objetives: To compare the results of the laparoscopic cholecystectomy with the cholecystectomy by adapted smaller incisions.

Design: Prospective and comparative protocolized study.

Apparent diffusion coefficient histogram analysis stratifies progression-free and overall survival in patients with recurrent GBM treated with bevacizumab: a multi-center study.

We have tested the predictive value of apparent diffusion coefficient (ADC) histogram analysis in stratifying progression-free survival (PFS) and overall survival (OS) in bevacizumab-treated patients with recurrent glioblastoma multiforme (GBM) from the multi-center BRAIN study. Available MRI's from patients enrolled in the BRAIN study (n = 97) were examined by generating ADC histograms from areas of enhancing tumor on T1 weighted post-contrast images fitted to a two normal distribution mixture curve. ADC classifiers including the mean ADC from the lower curve (ADC-L) and the mean lower curve proportion (LCP) were tested for their ability to stratify PFS and OS by using Cox proportional hazard ratios and the Kaplan-Meier method with log-rank test.

[Splenic cystic lymphagioma].

Splenic cystic lymphangioma is a very rare benign neoplasia characterized by cystic dilation of the lymphatic vessels of the splenic parenchyima. It may occur in the spleen only or in multiple organs. We describe the case of a 46 year-old female, with he diagnosis of splenic cystic lymphangioma.

The use of the Alvarado score in the management of right lower quadrant abdominal pain in the adult.

Aim Of The Study: The Alvarado score is a validated test in clinical adult surgery practice which can be helpful in the diagnosis of acute appendicitis. This study aimed to assess the reliability and the reproducibility of this score for patients presenting in the emergency room with acute right lower quadrant abdominal pain.

Material And Methods: A prospective monocenter study included all adults who presented in the emergency room with right lower quadrant abdominal pain.

Comparing the reliability of responses to telephone-administered versus self-administered Web-based surveys in a case-control study of adult malignant brain cancer.

Introduction: To determine whether a Web-based survey was an acceptable method of data collection for a clinic-based case-control study of adult brain cancer, the authors compared the reliability of paired responses to a main and resurvey for participants completing surveys by telephone (n=74) or self-administered on the Web (n=465) between 2003 and 2006.
