BACKGROUND We hypothesized that coronary blood flow (CBF) reserve could be quantified noninvasively in humans using myocardial contrast echocardiography (MCE). METHODS AND RESULTS Eleven patients with normal epicardial coronary arteries (group I) and 19 with single-vessel coronary stenosis (group II) underwent quantitative coronary angiography, MCE, and CBF velocity measurements at rest and d...
This study was conducted to determine whether pentoxifylline has an in vitro effect on sperm motion characteristics in normozoospermic men. The subjects of the study were 15 male volunteers. After the spermatozoa were washed with mBWW medium, the sperm suspension was divided into two aliquots: one was treated with 1 mg/ml pentoxifylline, the other was used as a control. The sperm motion charact...
BACKGROUND Percutaneous coronary intervention (PCI) aims to increase coronary blood flow by relieving epicardial obstruction. However, no study has objectively confirmed this and assessed changes in flow over different phases of the cardiac cycle. We quantified the change in resting and hyperemic flow velocity after PCI in stenoses defined physiologically by fractional flow reserve and other pa...
The effects of acute restraint stress on sperm motility and reproductive endocrinology were investigated in adult rats. Sperm motility was determined by computer-assisted sperm analysis. Acute restraint stress reduced sperm motility starting after 30 min, and the sperm motility parameters, percentage of motile spermatozoa (%), straight-line velocity, curvilinear velocity, deviation of the sperm...
Aims: Polyketide synthase 13 (Pks13) is an essential enzyme in the synthesis of mycolic acids biosynthesis pathway Mycobacterium tuberculosis (Mtb). Therefore, Pks13 a promising drug target for treatment. Here we report silico design and evaluation novel inhibitors made benzofuran derivatives with favorable predicted pharmacokinetic profiles.
 Methodology: A 3D model Pks13-TAMx complexes w...
Abstract This paper describes trajectory planning for an Autonomous Vehicle (AV) in the freeway path. Three types of driving modes are analyzed. First was free flow, this constitutes that moving at desired speed is determined beginning movement. Second case car following, when overtaking or lane-change impossible, distance adaptation executed using variable acceleration/deceleration strategy. T...
Research on digital collaboration scenarios in Higher Education (HE) is characterized by various approaches that often define the acquisition and development of global skills as learning goals. Virtual Collaborative Learning (VCL) HE represents one approach to facilitating students’ skills. Depending use case, these arrangements can include case study-based group under e-tutorial supervision. T...
in this study, flow characteristics through symmetric stenosis artery are investigated. the shape of eccentricity for stenotic flows is limited by circular-cross sections and plaques are usually assumed as to be oriented concentrically. thegoverningequationsaretheusualnavier-stokesequationsandare numericallysolved by using finite volumemethod in arbitrary orthogonal curvilinear coordinates. in ad...
Aims: The alleviating aspects of liquid vermicompost (VCL) on the seed germination and juvenile seedling growth Hungarian vetch, which is an important fodder plant in Turkey world, under salt stress were evaluated.Methods Results: Two experiments laboratory greenhouse conditions established according to a randomized plot design with three replications. In experiments, levels applied as control ...
A microelectromechanical system (MEMS) is a diminutive machine having electronic and mechanical components with size ranging from 20 µm-1 mm. In this present-day world, MEMS fabrication techniques have remodeled the conventional approaches towards fabrication. Microfluidics an eminent domain of in which small volumes fluids are disciplined micro-channels dimensions submillimeter to achieve desi...
