BACKGROUND The genetic and antigenic characteristics of influenza A viruses (IAV) within and between species change over time due to antigenic shift and drift. Although pigs are known to play a key role in the epidemiology of IAV between species, little is known about the molecular evolution of IAV hemagglutinin (HA) in pigs. OBJECTIVES The aim of this study was to evaluate the HA drift of an...

The eff ects of Dangguibuxue Tang (DBT) on growth performance and immunity response in immunosuppressed broiler chicks were investigated in this study. 240 one-d-old broiler chicks (DaHeng S01) were randomly divided into 4 groups, 2.0% DBT-treatment (A), 0.5% DBT-treatment (B), cyclophosphamide-control (C), and control group (D). From 4 d to 7 d of age, chicks in group A, B and C were given cyc...

Objectives: The aim of the present study was to investigate immunotoxic effect of safranal (SAF), a main component of Crocus sativus essential oil, using Balb/c mice. Materials and Methods: SAF was administered intraperitoneally at doses of 0.1, 0.5 and 1 ml/kg for 3 weeks. Hystopathological examination of spleen and bone marrow, cellularity of spleen, delayed type of hypersensitivity (DTH) res...

Background: Hydatid cyst is the larval stage of the tape worm parasite, Echinococcus granulosus. Human is infected by ingestion of parasite ova excreted in dog feces. The anticancer activity of different antigens of hydatid cyst has been reported in the previous works. In this research, the role of immune system in induction of this anticancer activity has been investigated.Materials and Method...

Pengendalian pandemi dengan penerapan protokol kesehatan telah membantu melandaikan kurva epidemi, namun belum dapat mengontrol penyebaran COVID-19 sehingga diperlukan strategi kekebalan kelompok (herd immunity) melalui program vaksinasi. Keraguan vaksin dan informasi yang salah menyebabkan hambatan besar untuk mencapai cakupan Herd Immunity di banyak negara. Tujuan penelitian ini adalah mengan...

Covid-19 had been the global pandemic cases across world since WHO declared it as diseases. It has crisis which impacted globally on health and economic sector at a time. This review article covered detail of COVID-19 in brief detail, its epidemiological data, herd immunity vaccination program, vaccine development status. Also this nanotechnology used process future prospective. concerned over ...

rubella or german measles is a mild contagious disease in non-pregnant women, but in pregnant affected mother’s possibility of fetus infection in the first twelve weeks of gestation is 80%. between 13-14 weeks of gestation is 54% and by the end of the second trimester is 25%. if fetus gets infected severe anomalies will progress. at present no vaccination against rubella is begin envisaged by t...

to evaluatethe effects of supplementing diets of growing japanese quails (n=450; 7 days old) with chromium (cr) yeast and / or mannan oligosaccharides (mos) on productive performance, carcass traits and the immune system are reported. diets were a basal diet (control) or the basal diet supplemented with 600 mg cr-yeast/kg (cr 1), 1200 mg cr-yeast/kg (cr 2), 1.0 g mos/kg, cr 1 + mos or cr 2 + mo...

background:class ii transactivator (ciita) is a dominanttranscriptional element, controlling numerous genes in theimmune system. ciita is expressed in a constitutive pattern inantigen presenting cells although its expression can occur inother cell types. since the revelation of ciita, there have beenconsiderable advances toward understanding its role as anactivator of mhc ii genes in humans and...
