Findings concerning selective slow pathway radiofrequency ablation for atrioventricular nodal reentrant tachycardia (AVNRT) using the slow pathway potential (SPP) guided method are reported. The electrogram at the SPP recording site showed double potentials consisting of the atrial potential (A) and SPP. However, SPP is usually recorded widely in the right atrial posteroseptal region. To examin...

BACKGROUND Pollen allergens are one of the main contributors to the development and/or aggravation of allergic rhinitis, allergic conjunctivitis, and asthma. OBJECTIVE An examination of the airborne pollen in residential areas should be conducted to aid the diagnosis and treatment of allergic diseases. METHODS Airborne pollen samples were collected from 2 sites in Incheon and 2 in Seoul fro...

This study was carried out on 1600 rectal swabs from children under 5 years of age admitted at the health centre in Islamshahr, Tehran province, Islamic Republic of Iran, during 1998-99. The specimens were examined for various bacterial pathogens. Isolation rates were: enteropathogenic Escherichia coli 6.8%, Shigella spp. 3.4%, Salmonella spp. 2.9%, Campylobacter spp. 0.9%, Yersinia spp. 0.7%. ...

conclusions the reason for difference in the detected snail genera in sampling sites may be due to various physicochemical factors. according to the current study, medically important snails exist in miangran lake and they could be a source of trematode infections for the local people. controlling measures after comprehensive studies should be applied. background some freshwater snails are acti...

We screened 768 tick pools containing 6,962 ticks from Khammouan Province, Laos, by using quantitative real-time PCR and identified Rickettsia spp., Ehrlichia spp., and Borrelia spp. Sequencing of Rickettsia spp.-positive and Borrelia spp.-positive pools provided evidence for distinct genotypes. Our results identified bacteria with human disease potential in ticks in Laos.

The aim of the study was to assess microbial quality of water in dental unit waterlines in a dental school at Mangalore. Methodology: Water samples were taken from tap water for control, air/water syringe and the high speed hand piece of 20 dental units. The samples were transferred to the laboratory and streaked on the culture media namely Mac Conkey agar, Sabourauds dextrose media, Buffered c...

A stromal processing peptidase (SPP) cleaves a broad range of precursors targeted to the chloroplast, yielding proteins for numerous biosynthetic pathways in different compartments. SPP contains a signature zinc-binding motif, His-X-X-Glu-His, that places it in a metallopeptidase family which includes the mitochondrial processing peptidase. Here, we have investigated the mechanism of cleavage b...

Weissella spp. are non-spore forming, catalase-negative, gram-positive coccobacilli. They are often misidentified by traditional and commercial phenotypic identification methods as Lactobacillus spp. or Lactobacillus-like organisms. Weissella spp. were previously grouped along with Lactobacillus spp., Leuconostoc spp., and Pediococcus spp. Utilization of more sensitive methods like DNA sequenci...
