Abstract In this work, we measured the I-V characteristics of silica nanoparticles (SNPs) extracted from Pleurosira laevis diatom and deposited on top a p-type Si(111) wafer. The electric response SNPs-based diode is found to be more sensitive thermal optical power than fresh frustules-based by about 3 5 times, respectively. Moreover, chemically processed SNPs exhibit better parameters, i.e. fo...

background hepatitis b virus (hbv) infection is a serious public health problem in china and worldwide. mother-to-child transmission is one of hbv’s main transmission routes in highly endemic regions. genome-wide association studies (gwas) identify single nucleotide polymorphisms (snps) at hla loci as associated with hbv infection. however, the mechanisms of hbv perinatal transmission and break...

Tomato Fusarium wilt caused by oxysporum f.sp. lycopersici (Fol) constrains tomato production worldwide. Three hundred forty accessions were evaluated for resistance and single nucleotide polymorphisms (SNPs) associated with resistance. The disease evaluation revealed that 15, 13, 15 identified as resistant in Test 1, 2, Mean data, respectively, the severity index (DSI) ranging from 0-16.7%. A ...

Background: Unexplained recurrent spontaneous abortion (URSA) has been suggested being associated with the failure of fetal-maternal immunologic tolerance in which the regulatory T lymphocytes (Tregs) play a crucial role. Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is expressed transiently on activated T cells and constitutively on Tregs. CTLA-4 interacts with the B7 cell surface molec...

The main goal of our study was to determine whether biosynthesized silver nanoparticles (SNPs) could be used as a novel antibacterial material in order control soft rot vegetables. Exudates from oak fruit were the green synthesis SNPs. Postharvest disease vegetables has resulted significant crop losses all over globe. Because managing Pectobacterium carotovorum subsp. (Pcc), causal agent diseas...

background: multiple sclerosis (ms), a chronic inflammatory demyelinating disorder with neurodegenerative aspects, is more common among young adults, particularly women. methods: this molecular study was designed to investigate the il-7r α chain gene in iranian ms patients. we studied 60 ms patients, diagnosed based on 2005 r-mcdonald criteria and 60 apparently healthy individuals as the contro...

The objective of this study was to evaluate the imputation accuracy of parent-offspring trios under different scenarios. By using simulated datasets, the performance Bayesian LASSO in genomic prediction was also examined. The genome consisted of 5 chromosomes and each chromosome was set as 1 Morgan length. The number of SNPs per chromosome was 10000. One hundred QTLs were randomly distributed a...

evidences indicate that angiogenesis  is an important process in the development of destructive synovial tissue in rheumatoid  arthritis (ra). recently, it has been shown that the polymorphism of the integrin-αv subunit encoded by the itgav gene plays a role in angiogenesis and is considered  as ra susceptibility loci. this study investigated association of four single nucleotide polymorphisms ...
