INTRODUCTION Intra-operative complications like mechanical damages to the leads, infections and hematomas during generator replacements of implantable pacemakers and defibrillators contribute to additional costs for hospitals. The aim of this study was to evaluate operation room use, costs and budget impact of generator replacements using either a traditional surgical intervention (TSI) with sc...

This study examined the effect of an orally active thromboxane (TXA2) synthetase inhibitor (TSI) on the patency, TXA2 production, and platelet accumulation of reversed autogenous vein grafts. Ten dogs received TSI (U-63557A) 10 mg/kg po q8 hr for 6 weeks, beginning 24 hr prior to surgery, while 15 control dogs were untreated. One jugular vein was harvested and stored in 37 degrees C saline for ...

Abstract The study was conducted to assess the spatial and temporal variations of trophic state condition Lake Bunyonyi between October 2019 September 2020. Secchi depth (SD), total phosphorus (TP) chlorophyll- a (Chl- ) concentration were measured aid quantification lake using Carlson index (CTSI). (TSI) values based on SD, TP Chl- 60.82 ± 5.35, 68.99 11.04 61.74 7.51, respectively. March 2020...

Optical packet switching can seamlessly integrate data networking and optical networking [1]. Recent advances in optical technology make it possible to create systems with the capability to do switching in multiple domains (time, space and wavelength). Time-slot-interchange (TSI) is a form of network switching in time domain. Previous experimental TSI systems involve semiconductor laser amplifi...

PURPOSE To establish an effective system for isolating primary retinal ganglion cells (RGCs) from newborn mice. METHODS The retinas were separated from enucleated eyeballs of Crl:CD-1 mice on postnatal day 1 to 4. RGCs were purified using three different methods, including two-step immunopanning (TSI), direct magnetic separation (DMS), and immunopanning-magnetic separation (IMS). Harvested ce...

Population exposure to multiple chemicals in air presents significant challenges for environmental public health. Air quality regulations distinguish criteria air pollutants (CAPs) (e.g., ozone, PM2.5) from hazardous air pollutants (HAPs)-187 chemicals which include carcinogens and others that are associated with respiratory, cardiovascular, neurological and numerous other non-cancer health eff...

Chapter 2 provides an overview of solar irradiances, the dominant energy input driving Earth’s climate. The uninterrupted 33-year long total solar irradiance (TSI) record from space-borne instruments requires sufficient stability for climate-quality studies, helping determine the global and regional sensitivities of Earth’s climate to solar variability. New instrument calibration capabilities h...

OBJECTIVE This study examined the prevalence and psychological sequelae of childhood sexual and physical abuse in adults from the general population. METHOD A national sampling service generated a geographically stratified, random sample of 1,442 subjects from the United States. Subjects were mailed a questionnaire that included the Traumatic Events Survey (TES) [Traumatic Events Survey, Unpu...

Botulinum neurotoxins are highly effective therapeutic products. Their therapeutic success results from highly specific and potent inhibition of neurotransmitter release with a duration of action measured in months. These same properties, however, make the botulinum neurotoxins the most potent acute lethal toxins known. Their toxicity and restricted target cell activity severely limits their cl...

In human immune deficiency virus (HIV)-seropositive hemophilia patients, a low number of CD4 + lymphocytes is found, as well as a low CD4+/CD8+ ratio. In previous studies, it has been shown that antigen-specific T-helper cell (CD4+) function was present and no excessive antigen-specific T-suppressor cell (CD8+) function could be demonstrated. In this report, we studied another activity of CD4+ ...
