در قرن اخیر با رشد روزافزون جمعیت شهرنشین، مشکلات متعددی در زمینۀ آلودگی و کیفیت منابع آبی مطرح شده است. بنابراین، شناخت و مطالعۀ فرایندهای اختلاط و انتقال مواد در رودخانهها از جمله فعالیتهای مهم در برنامههای مدیریت منابع آب به شمار میآید. بین فرایندهای اختلاط، پس از پدیدۀ انتشار طولی، فرایند انتشار عرضی آلودگی، تأثیرگذارترین پارامتر محسوب میشود. با توجه به اهمیت انتقال و چگونگی انتشار آلو...
This experiment was carried out at the Agricultural Research Station of Bu-Ali Sina University to study the effect of different tillage methods on bulk density, yield, and yield components of barley (Hordeum vulgare) cultivars under rainfed conditions. Three levels of tillage (CT: conventional tillage, MT: minimum tillage and NT: no tillage) and five barely cultivars (V1: Local V2: AbidarV3: ...
Statistical analysis of nucleotide sequences of the hemagglutinin gene of human influenza A viruses.
To examine whether positive selection operates on the hemagglutinin 1 (HA1) gene of human influenza A viruses (H1 subtype), 21 nucleotide sequences of the HA1 gene were statistically analyzed. The nucleotide sequences were divided into antigenic and nonantigenic sites. The nucleotide diversities for antigenic and nonantigenic sites of the HA1 gene were computed at synonymous and nonsynonymous s...
background: influenza viruses are a significant cause of morbidity and mortality. the influenza virus pandemics, 1918, 1977, and especially the most recent one, a/h1n1/2009, made evident the need for generating recombinant influenza h1n1 antigens which are essential to develop both basic and applied research programs. among influenza virus proteins, haemagglutinin (ha) is a major surface antige...
Consecutive cases of human infection with H7N9 influenza viruses since 2013 in China have prompted efforts to develop an effective treatment. Subunit vaccines introduced by intranasal administration can block an infection at its primary site; flagellin (fliC) and polyethyleneimine (PEI) have been shown to be potent adjuvants. We previously generated the hemagglutinin (HA)1-2-fliC fusion protein...
Accumulation of hepatic zinc via metallothionein (MT) induction during infection/inflammation is postulated to benefit a range of metabolic processes. The metabolic consequences of two doses of endotoxin (LPS) (1 and 5 mg/kg, intraperitoneally) were examined in normal (MT+/+) and MT-null (MT-/-) mice (all results means =/- S.E.M., n=6). At 16 h after 1 mg/kg LPS, hypozincaemia was pronounced in...
Given the repeated failure of amyloid-based approaches in Alzheimer's disease, there is increasing interest in tau-based therapeutics. Although methylthioninium (MT) treatment was found to be beneficial in tau transgenic models, the brain concentrations required to inhibit tau aggregation in vivo are unknown. The comparative efficacy of methylthioninium chloride (MTC) and leucomethylthioninium ...
Methylmercury (MeHg) is a widespread environmental contaminant that causes reproductive dysfunction in men. Metallothioneins (MTs) are low-molecular-weight proteins that can bind heavy metals and protect the cell from metal toxicity. MT levels are increased by exposure to metals and physiological stressors. Although MTs have been identified in the testis and epididymis, little is known about th...
Development of effective vaccines to prevent influenza, particularly highly pathogenic avian influenza (HPAI) caused by influenza A virus (IAV) subtype H5N1, is a challenging goal. In this study, we designed and constructed two recombinant influenza vaccine candidates by fusing hemagglutinin 1 (HA1) fragment of A/Anhui/1/2005(H5N1) to either Fc of human IgG (HA1-Fc) or foldon plus Fc (HA1-Fdc),...
Information on the antigenic structure of influenza hemagglutinin (HA) has been deduced previously from sequence analyses of laboratory mutant viruses selected, in vitro, with neutralizing monoclonal antibody (mAb) established exclusively from BALB/c (H-2d) mice; and there has been no attempt to investigate the influence of host genetic background, or natural route of infection, on the protecti...
