Impairments of attention in RRMS patients: the role of disease duration.

Introduction: The extent to which different types of attention are affected in RRMS based on disease duration has not been extensively analyzed. Therefore, the aim of this study was to determine whether MS patients differ compared to healthy individuals in a homogeneous sample of RRMS patients in terms of attention types and from which year of MS attention deficit starts. Another aim of the study was to examine the effect of MS duration and stimulus onset asynchrony on dual task performance.

Comprasion of ovarian stromal blood flow measured by color Doppler ultrasonography in polycystic ovary syndrome patients and healthy women with ultrasonographic evidence of polycystic.

Objective: To compare ovarian stromal artery blood flows measured by Doppler ultrasonography of polycystic ovary syndrome (PCOS) patients and healthy women with polycystic ovarian image in ultrasonography.

Methods: Forty-two patients diagnosed with PCOS according to the criteria of 2003 Rotterdam Concencus Conferance on PCOS and 38 healthy volunteers with polycystic ovarian image in ultrasonography were included in the study. Ovarian volumes and ovarian stromal artery blood flows were measured by 3-dimensional (3-D) ultrasonography and Doppler ultrasonography in all patients.

Serum galectin-3 levels in women with PCOS.

Aim: Galectin-3 (Gal-3) plays a role in modulation of adiposity, glucose hemostasis and inflammation. The association between Gal-3 and the polycystic ovary syndrome (PCOS), is not investigated. We aimed to evaluate galectin-3 levels in serum and their relation with hyperandrogenism and insulin resistance (IR) in women with polycystic ovary syndrome (PCOS) and in control subjects.

Parvalbumin-containing interneurons of the human cerebral cortex express nicotinic acetylcholine receptor proteins.

Cholinergic fibers from the basal forebrain are known to contact cholinoceptive cortical pyramidal neurons. Recent electrophysiological studies have revealed that nicotinic acetylcholine receptors are also present in human cerebrocortical interneurons. A direct visualization of nicotinic receptor subunits in cortical interneurons has, however, not yet been performed.
