The purpose of this study was to test the hypothesis whereby eye movements as such may be an important factor in the development of motion sickness (MS). The horizontal eye movements of 27 subjects were measured during earth vertical axis rotation (EVAR) and during off vertical axis rotation (OVAR). Two groups were set up, one including subjects who suffered severe MS during the test, and the o...

objective: type 1 diabetes mellitus (t1d) is an autoimmune and multifactorial disorder. subsequent analysis on human leukocyte antigen ( hla) region shows that hla-drb1 and -dqb1 genes have the strongest association with t1d. in this study, for the first time, we investigated the influence of gender on the hla-drb1 and -dqb1 association with type 1 diabetes mellitus in iranian patients in order...

The present study was aimed to analyze the frequencies of human leukocyte antigen (HLA)-A, -B, and -DRB1 alleles and A-B-DRB1, A-B, A-DRB1 and B-DRB1 haplotypes in inhabitants of Guizhou province, China. All samples were typed in the HLA-A,-B, and -DRB1 loci using the polymerase chain reaction-reverse sequence specific oligonucleotide probe (PCR-rSSOP) method and HLA polymorphisms were analyzed...

Background Nauseogenicity is determined by exposure time, frequency and acceleration of real motion. Our aim was to determine the nauseogenicity of these parameters for the optokinetic equivalent of OVAR (Off Vertical Axis Rotation). Methods The visual stimulus was a computerised scene of coastline as seen by a 'pilot' at moderate altitude. The scene could be rotated at different frequencies an...

Constant velocity Off-Vertical Axis Rotation (OVAR) imposes a continuously varying orientation of the head and body relative to gravity, which generates a modulation of horizontal (conjugate and vergence), vertical, and torsional eye movements. We introduced the head-turn-on-trunk paradigm during OVAR to examine the extent to whether the modulation of these ocular reflexes is mediated by gravic...

Multiple sclerosis (MS) is a complex trait in which alleles at or near the class II loci HLA-DRB1 and HLA-DQB1 contribute significantly to genetic risk. HLA-DRB1*15 and HLA-DRB1*17-bearing haplotypes and interactions at the HLA-DRB1 locus increase risk of MS but it has taken large samples to identify resistance HLA-DRB1 alleles. In this investigation of 7,093 individuals from 1,432 MS families,...

Human leukocyte antigens class II play an important role in immune response against HCV. We investigated whether HLA class II alleles influence susceptibility to HCV infection and response to interferon therapy. HLA-DRB1 and -DQB1 loci were genotyped using PCR-SSO Luminex technology. According to our regimen, 41 (66%) of patients achieved sustained virological response to combined treatment of ...

BACKGROUND The relationship between HLA-DRB1 alleles and asthma is controversial. The purpose of this study was to evaluate the relationship between HLA-DRB1 alleles and risk of asthma. MATERIAL AND METHODS We searched PubMed, Chinese National Knowledge Infrastructure (CNKI), Wan Fang (Chinese) database, and Chinese Biomedical Medical databases (CBM) to find studies on the relationship between ...
