AIM The virulence-associated protein-A of Staphylococcus aureus, encoded by spa gene shows a variation in length in different strains. In this study, the spa gene variation in S. aureus strains was studied which were isolated from subclinical cases of bovine mastitis. MATERIALS AND METHODS About 38 isolatesof S. aureus were recovered from Holstein-Friesian (HF) crossbred (n=16) and Rathi catt...

Flexible Dual-TCP/UDP Streaming Protocol with Bitstream Prioritization (FDSP-BP) is a new method for streaming H.264-encoded High-definition (HD) video over wireless networks. This paper presents a novel technique to adaptively modify the Bitstream prioritization (BP) parameter based on network conditions. This technique selects the maximum BP value that satisfies the Transmission Control Proto...

The Tibetan Plateau (TP) is primarily influenced by the northern hemispheric middle latitude Westerlies and the Indian summer monsoon (ISM). The extent, long-distance effects and potential long-term changes of these two atmospheric circulations are not yet fully understood. Here, we analyse modern airborne pollen in a transition zone of seasonally alternating dominance of the Westerlies and the...

Marek’s disease (MD) is a lymphoproliferative disease of chickens characterized by lymphocyticinfiltration of various organs. The present study was an attempt to use polymerase chain reaction (PCR) tooptimize a rapid and reliable assay for detection of MDV genome. Detection of serotype 1 of MDV (MDV-1)was confirmed by presence of a 200 bp DNA fragment as a PCR product. Differentiation of MDV-1 ...

OBJECTIVE To study cardiovascular behavior and safety regarding a low-intensity exercise program for heart transplant candidates with severe heart failure. METHODS Twenty-one patients with severe heart failure on the transplant list of the UNIFESP university hospital (Brazil) were studied. Following evaluation, the patients were monitored during an exercise program with six progressive phases...

The upper size limit of solar small-scale magnetic flux concentrations (“G-band bright points”, BP) is reconsidered from speckle-reconstructed images taken at the 1-m SST on La Palma. The size-histogram shows a sharp drop towards 250 km diameter, variation of the noise filter threshold diminishes that value due to segmentation of the elongated structures. A further artificial segmentation of st...

We report experiments designed to test homology dependence for gene conversion between duplicated chromosomal sequences in cultured mammalian cells. The experimental system is such that gene conversion events not associated with reciprocal exchange are recoverable. For this study four plasmids were constructed. Each contains a different duplication of the herpes simplex virus thymidine kinase (...

Custom sequence capture experiments are becoming an efficient approach for gathering large sets of orthologous markers in nonmodel organisms. Transcriptome-based exon capture utilizes transcript sequences to design capture probes, typically using a reference genome to identify intron-exon boundaries to exclude shorter exons (<200 bp). Here, we test directly using transcript sequences for probe ...
