conclusions high hvr diversity among the studied mrsa isolates could be a result of insufficient or inadequate infection-control protocols in tabriz hospitals. moreover, the high number of hvr genotypes showed that hvr typing can be used along with other typing methods in epidemiological studies of mrsa as a useful tool for monitoring, tracking contaminations, and controlling infections in hosp...

background: methicillin resistant staphylococcus aureus (mrsa) is a common major human pathogen that causes hospital-acquired infections. characterization and typing of the staphylococcal cassette chromosome has led to a better understanding of mrsa infection cycle in hospital. the meca-associated hypervariable region size classifies mrsa isolates that colonized in nasal carriers. objectives: t...

BACKGROUND Specific HLA class II alleles are associated with systemic sclerosis (SSc) risk, clinical characteristics, and autoantibodies. HLA nomenclature initially developed with antibodies as typing reagents defining DRB1 allele groups. However, alleles from different DRB1 allele groups encode the same third hypervariable region (3rd HVR) sequence, the primary T-cell recognition site, and 3rd...

Human astroviruses (HAstV) are causative agents of viral gastroenteritis worldwide. A hypervariable region (HVR) is located close to the C-terminus of the nsP1a, and recent data support the involvement of the HVR-containing nonstructural protein in viral RNA replication processes, suggesting a correlation between variability in this region and pathogenic properties. The HVR of the C-terminal ns...

In homicides with entomological evidence, it may be important to prove the presumed association of fly larvae to a corpse, especially if it is in doubt whether all maggots used for entomological expertise developed and fed on it. The present study demonstrates for the first time the possibility of analyzing human microsatellite DNA present in the digestive tract of necrophagous larvae that fed ...

Methods for measuring the ventilatory response to hypoxia (HVR) are reviewed. The criteria for success as a high altitude mountaineer are defined as freedom from acute mountain sickness (AMS) and ability to perform well at extreme altitude. The evidence for a brisk HVR being protective against AMS and associated with successful high altitude performance is reviewed. The contrary evidence of blu...

The present study evaluated whether slow-wave sleep and whole-night delta power of the non-rapid eye movement (NREM) sleep electroencephalogram (EEG) decrease during sleep at a simulated altitude of 2000 m, and whether such changes related to measures of hypoxic ventilatory response (HVR). This study consisted of two parts; in the first, HVR was measured in 41 subjects and each seven subjects w...

OBJECTIVES Patients with left atrial isomerism and interrupted inferior vena cava palliated with a superior cavopulmonary connection or Kawashima procedure (KP) have a high incidence of developing pulmonary arteriovenous malformations. The necessity for hepatic vein redirection (HVR) and its timing remains a controversy. We aimed to assess the clinical outcome of patients with left atrial isome...

A hypervariable region (HVR) previously identified in the carboxy-terminal one-third of the Babesia bovis variable merozoite surface antigen family was more extensively analyzed in merozoite surface antigen 1 (MSA-1) from 16 strains and isolates. The MSA-1 HVR is proline rich and contains three semiconserved motifs nearly identical to those described for the related family member MSA-2. Two MSA...
