Purpose: The objective of the present study was to evaluate the capacity of the myocardium for energy production by the analysis of mitochondrial respiration in rats with jaundice submitted to bile duct ligature. Methods: Sixteen male Wistar rats were divided into 2 Groups: Group SO submitted to nontherapeutic laparotomy (sham operation) and Group IC (icteric group) submitted to bile duct ligat...

[Purpose] The purpose of this study was to examine the effects of smoking on teenagers' internal oblique (IO) and transverses abdominis (TrA) expiratory muscles and their pulmonary function. [Subjects] A total of 30 healthy teenagers (15 smokers; 15 nonsmokers) voluntarily participated in the study. [Methods] The subjects were instructed to maintain an upright standing posture with their scapul...

Transverse-electric (TE) surface plasmons (SPs) are very unusual for plasmonics phenomenon. Graphene proposes a unique possibility to observe these plasmons. Due to transverse motion of carriers, TE SPs speed is usually close to bulk light one. In this work we discuss conditions of TE SPs propagation in cylindrical graphene-based waveguides. We found that the negativity of graphene conductivity...

The Rudiviridae are a family of rod-shaped archaeal viruses with covalently closed, linear double-stranded DNA (dsDNA) genomes. Their replication mechanisms remain obscure, although parallels have been drawn to the Poxviridae and other large cytoplasmic eukaryotic viruses. Here we report that a protein encoded in the 34-kbp genome of the rudivirus SIRV1 is a member of the replication initiator ...

The Bacterial Endotoxins Test (BET) uses Limulus amoebocyte lysate (LAL) reagents derived from the blood of horseshoe crabs for detection and quantification endotoxins Gram-negative bacteria in parenteral drug products medical devices. Two types recombinant using genes cloned crab genome have become available several suppliers. One is a Factor C reagent (rFC), containing only C, second Cascade ...

We conducted a study to determine if platelet-rich plasma (PRP) enhances the strength of rotator cuff repair (RCR) and if concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) affects PRP efficacy. We also wanted to determine the optimal centrifugation protocol for making PRP from rats. This study used 48 rats, 14 in a centrifugation protocol and 34 in an operative protocol. Six syng...

1 Recursive Context Reasoning for Human Detection and Parts Identi cation Liang Zhao and Chuck Thorpe The Robotics Institute Carnegie Mellon University Pittsburgh, PA 15213 Email: [email protected] Abstract Human detection and body parts identi cation are important and challenging problems in computer vision. High performance human detection depends on reliable contour extraction, but contour ex...

Propagation of genetic information is a fundamental property of living organisms. Escherichia coli has a 4.6 Mb circular chromosome with a replication origin, oriC. While the oriC replication has been reconstituted in vitro more than 30 years ago, continuous repetition of the replication cycle has not yet been achieved. Here, we reconstituted the entire replication cycle with 14 purified enzyme...

Aerobic interval training (AIT) can favorably affect cardiovascular diseases. However, the effects of AIT on post-myocardial infarction (MI)-associated mitochondrial dysfunctions remain unclear. In this study, we investigated the protective effects of AIT on myocardial mitochondria in post-MI rats by focusing on mitochondrial dynamics (fusion and fission). Mitochondrial respiratory functions (a...

In this work we report a relatively simple and fast method for analysing oxygen consumption and therefore mitochondrial functionality, in individual human ejaculates. This oxygraphic method requires a low number of cells, is highly reproducible and linearly correlates with sperm concentration. Our results have shown that oxygen uptake by mitochondria of demembranated sperm cells from normozoosp...
