In this study, bit error rate (BER) performance of multiple input multiple output (MIMO) systems employing transmit antenna selection with maximal ratio combining (TAS/MRC) and orthogonal space time block codes (OSTBC) is analysed and compared. Analysis has been done for several modulation schemes in equicorrelated Rayleigh fading channels. Novel infinite series expressions for BER of TAS/MRC a...

We report a detailed study of electrical and thermal transport properties in 2H-M$_x$TaS$_2$ (M = Mn, Co) magnets where M atoms are intercalated the van der Waals gap. The intercalation induces ferromagentism with an easy-plane anisotropy 2H-Mn$_x$TaS$_2$, but ferromagnetism strong uniaxial 2H-Co$_{0.22}$TaS$_2$, which finally evolves into three-dimensional antiferromagnetism 2H-Co$_{0.34}$TaS$...

PURPOSE Investigators are currently conducting phase II trials on TAS-108, a novel oral steroidal antiestrogenic agent. The purpose of this study is to investigate the molecular and pharmacologic properties of TAS-108 compared with other antiestrogenic agents such as tamoxifen,raloxifene, and fulvestrant. EXPERIMENTAL DESIGN The antagonistic or agonistic activities of these agents against bot...

OBJECTIVES To compare the mean total antioxidant status (TAS) among 3 glaucoma types, namely: pseudoexfoliation glaucoma (PEG), primary open angle glaucoma (POAG), and primary angle closure glaucoma (PACG), and study its potential association with various clinical glaucoma-parameters.   METHODS In this case-control study, plasma samples were obtained between September 2013 and October 2014 fr...

BACKGROUND An imbalance between reactive oxygen species (ROS) generation in sperm and antioxidant capacity of seminal plasma has been linked to male infertility. The antioxidant power of biological fluids can be evaluated either by measurement of individual antioxidants or total antioxidant capacity (TAC). The aim of this study was to assess whether TAS Randox can also be used for seminal plasm...

The purpose of this study was to determine the efficacy and the possible mechanism of action of a recently synthesized drug, TAS-301 [3-bis(4-methoxyphenyl)methylene-2-indolinone], on stenosis after balloon overstretch injury of porcine arteries. We measured the diameter of vessels by angiography and conducted histological analysis. The oral administration of TAS-301 kept dilated the angiograph...

A lot of studies showed the role of oxidative stress in more than 100 diseases, many neurodegenerative diseases and also in ischemic stroke. Objective: to assess the variation of oxidative stress in the acute phase of ischemic stroke and to find if there is any correlation with the clinical status or with any other biochemical parameter. Methods: We prospectively studied markers of oxidative st...

Toxin-antitoxin systems (TAs) are ubiquitous among bacteria and play a crucial role in the dissemination and evolution of antibiotic resistance, such as maintaining multi-resistant plasmids and inducing persistence formation. Generally, activities of the toxins are neutralised by their conjugate antitoxins. In contrast, antitoxins are more liable to degrade under specific conditions such as str...

INTRODUCTION Oxidative stress is now recognized as being the cause and the consequence of cardiovascular diseases. OBJECTIVE The role that oxidative stress parameters and inflammatory markers may play in diabetes and related cardiovascular disease (CVD) among Tunisian coronary diabetic patients. PATIENTS AND METHODS We measured the erythrocyte glutathione peroxidase (GPX), the superoxide di...

In many organisms, an increasing number of proteins seem to play two or more unrelated roles. Here we report that maize sucrose synthase (SUS) is distributed in organelles not involved in sucrose metabolism and may have novel roles beyond sucrose degradation. Bioinformatics analysis predicts that among the three maize SUS isoforms, SH1 protein has a putative mitochondrial targeting peptide (mTP...
