Identification of the pathogenic mutations underlying autosomal recessive nonsyndromic hearing loss (ARNSHL) is difficult, since causative mutations in 39 different genes have so far been reported. After excluding mutations in the most common ARNSHL gene, GJB2, via Sanger sequencing, we performed whole-exome sequencing (WES) in 30 individuals from 20(More)
Natural killer (NK) cell activity has been postulated to be an immunologic link between beta-carotene and cancer prevention. In a cross-sectional, placebo-controlled, double-blind study we examined the effect of 10-12 y of beta-carotene supplementation (50 mg on alternate days) on NK cell activity in 59 (38 middle-aged men, 51-64 y; 21 elderly men, 65-86 y)(More)
OBJECTIVE Mutations in the GJB2 gene has been reported as a main cause for autosomal recessive non-syndromic hearing loss (ARNSHL) all over the world. IVS1+1G>A which is splice site mutation have been detected in several populations as disruptive mutation. This study has intended to assess the significance of this mutation, IVS1+1G>A, to the autosomal(More)
Dietary fish oil, vitamin E, and probucol have been considered in a variety of human and experimental models of kidney disease. Using subtotal nephrectomized cholesterol-fed rats as a model for progressive kidney disease, we examined the effect of 5% dietary fish oil, or a combination of 5% dietary fish oil with 500 IU vitamin E/kg diet or 1% probucol on(More)
To determine the effects of long-term beta-carotene supplementation on concentrations of carotenoids and tocopherols in plasma and in blood cells, fasting blood was collected from 73 randomly selected physicians from the Boston area who are participating in the Physicians Health Study (PHS). The PHS is a randomized, placebo-controlled, double-blind study.(More)
BACKGROUND Age related macular degeneration (AMD) is the leading cause of irreversible blindness in the elderly population. Inflammatory mediators play an important role in AMD pathogenesis and immune-related gene polymorphisms are shown to increase the risk. Complement system is an important mediator of the immunity system and several genes encoding(More)
INTRODUCTION Depending on the response to standard steroid therapy, nephrotic syndrome it is classified to steroid-sensitive and steroid-resistant nephrotic syndrome (SRNS). Mutations in several genes including NPHS2 have been implicated in SRNS. Gene R229Q polymorphism (p.R229Q) of NPHS2 is associated with adolescent- or adult-onset SRNS in European and(More)
OBJECTIVE Mutations in GJB2 and GJB6 which comprise DFNB1 locus cause up to half of all cases of the prelingual autosomal recessive non-syndromic hearing loss (ARNSHL) worldwide. This study has intended to assess the spectrum and frequency of GJB2/GJB6 mutations in northwest of Iran. METHODS 508 Patients with presumed ARNSHL were analyzed by applying(More)
BACKGROUND Biliary atresia (BA) is a progressive inflammatory destructive process of the bile ducts. This study evaluated the relationship between single-nucleotide polymorphisms in the promoter region of tumour necrosis factor-alpha (TNF-α) gene and bilaiary atresia. MATERIALS AND METHODS Genomic deoxyribonucleic acid from 16 patients with established(More)
