Leishmania are parasitic protozoa with two major stages in their life cycle: flagellated promastigotes that live in the gut of the insect vector and nonflagellated amastigotes that live inside the lysosomes of the vertebrate host macrophages. The Pro-1 glucose transporter of L. enriettii exists as two isoforms, iso-1 and iso-2, which are both expressed primarily in the promastigote stage of the...

A pair of siblings, both of whom had neonatal thrombocytopenic purpura, are described. During the first pregnancy, the mother was given chlorothiazide and the implications of this therapy are considered. At the end of the second pregnancy a platelet iso-antibody was detected in the maternal serum. The possible reason for not detecting this antibody in the serum of the second child is considered.

Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failur...

Catecholamines induce intracellular reactive oxygen species (ROS), thus enhancing diastolic Ca2+ leakage through the ryanodine receptor during heart failure (HF). However, little is known regarding the effect of atrial natriuretic peptide (ANP) on ROS generation and Ca2+ handling in failing cardiomyocytes. The aim of the present study was to clarify the mechanism by which an exogenous ANP exert...

Although several methods have been reported on the analysis of the oxidative stress marker 15(S)-8-iso-prostaglandin-F2alpha (8-iso-PGF2α) in biological fluids, they either involve extensive sample preparation and costly technology or require high sample volume. This study presents a sample preparation method that utilizes low sample volume for 8-iso-PGF2α analysis in plasma and urine by an enz...

Assessment of Urinary F2-Isoprostanes in Experimental and Clinical Studies: Mass Spectrometry Versus ELISA To the Editor: Ojeda and colleagues reported that oxidative stress renal markers contribute to sex differences in blood pressure in adult growth-restricted offspring rats. The antibody used in the ELISA kit used by Ojeda et al isspecificfor15(S)-8-iso–PGF2 , 2 (http://www.oxfordbiomed.com/...

component of a mixed population of erythrocytes is sensitized by treating the mixture with a specific iso-antibody. After washing, the sensitized minor population erythrocytes are treated with antiglobulin serum. After further washing, a suspension of sensitized, washed erythrocytes is introduced into the mixture to provide a source of globulin coated particles with which tile available antiglo...

This study was aimed to determine whether beta-adrenergic receptor (beta-AR) stimulated by isoproterenol (ISO) activates signal transducers and activators of transcription (STAT) in mouse heart and, if so, to examine the underlying mechanism. We found that treatment of adult male mice by ISO (15 mg/kg body weight, intraperitoneal) caused a delayed STAT3 activation (at 60-120 min), which was ful...
