conclusions although significant differences (p < 0.01) were observed in the frequency of ttmdv/sav between healthy controls and each of the hiv positive and hiv/hcv co-infected individuals, no significant difference was observed between hiv positive and hiv/hcv co-infected cases, which may be due to hiv associated immunodeficiency. this is the first time that ttmdv/sav is reported in hiv infec...

biosecurity in the production of broiler chickens is very important but it is hard or even impossible to maintain; hence, promotion of immune responses could control diseases in chickens. at present study, the effect of six levels of oil-extracted propolis (0, 50, 100, 150, 200 and 250 mg/kg ration) on immune system against newcastle virus was studied using a completely randomized design with 3...

human t lymphotropic virus type i (htlv-i) is a retrovirus which is associated with adult t cells leukaemia (atl) and htlv-i-associated myelopathy/tropical spastic paraparesis (ham/tsp) in a minority of htlv-i-infected individuals. it is not clear why a minority of htlv-i-infected individuals develop ham/tsp and majority remains lifelong carriers. it seems that the interaction between the virus...

Seroepidemiological surveys are epidemiological studies carried out by the use of serum tests to detect infection; they can be applied to infections in general and to vaccine-preventable diseases in particular. Among other applications, seroepidemiological studies are useful for determining groups at risk for a specific disease; evaluating transmission mechanisms; and determining population gro...

to improve commercial grapevine cultivars, it is necessary to apply such methods that by cultivation of a certain number of vines in a certain area, higher yield could be harvested. to achieve such a goal, healthy stocks with resistant to pests and diseases, high fructification and high quality of vines are needed. all these properties can be obtained successfully through clonal selection. viti...

Background: Pyroptosis is defined as programmed necrosis executed by gasdermin D or E (GSDMD GSDME), which punches cellular membrane. Morphologically, pyroptosis characterized cell swelling and membrane rupture, leading to the release of contents that triggers intense inflammatory response. More more studies have found may be involved in pathogenesis viral infection, a determinant for inflammat...

Background: Infectious diseases are major public health problems, among which blood-borne ones are the most important infections. Patients who undergo orthopedic surgery are at higher risk of transmitting infectious diseases from and to others, due to repeated blood examinations and injection, drains secretion and receiving blood products. Accordingly, in this study we determined prevalence of ...
