the objective of this study was to evaluate the effect of accell connexus(®) on the quality and rate of healing in experimental defects of rabbit calvarium compared to bio-oss®.twelve 2.5-3.5 kg weighing new zealand white rabbits were used. three defects (3×6 mm) were created in the cranium of the animals subsequently filled with accell connexus(®), bio-oss® or served as controls. the animals w...

the purpose of this study was to evaluate the efficacy of two types of bone substitutes, bio-oss and nuoss, for repair of bone defects.this study was performed on the calvaria of 14 new zealand rabbits. the 6mm critical size defect (csd) models of bone regeneration were used. three csds were created in each surgical site. the first defect was filled with nuoss, the second one with bio-oss and t...

background and aims: bovine leukaemia virus (blv) is an oncogenic member of the genus deltaretrovirus of the family retroviridae. blv is the causative agent of enzootic bovine leukaemia and infects cattle worldwide, imposing economic impact on the dairy cattle industry. the purpose of this study was to estimate the seroprevalence of blv in cattle in some provinces of iran. materials and methods...

background bovine viral diarrhea (bvd) is an economically important disease of cattle with a worldwide distribution. diagnosis of bvd relies on laboratory-based detections of its viral causing agent or virus specific antibodies. the most common laboratory method used for this purpose is the elisa. bovine viral diarrhea virus (bvdv) nonstructural protein 3 (ns3) is one of the most highly conserv...

bovine leukosis virus (blv) is a retrovirus that primarily affects lymphoid tissue of cattle. to determine the seroprevalence of enzootic bovine leukosis virus infection and its effects on some clinical, hematological and flow cytometric indications, this study was conducted on 197 holstein cattle slaughtered in an abattoir in tehran province. elisa gp51 test of the obtained serums of the anima...

In this study, primary and immortalized bovine intestinal epithelial cells (BIECs) were characterized for the expression of surface carbohydrate moieties. Primary BIEC-c4 showed staining greater than 90 % 16 lectins but less 50 four lectins. Immortalized BIECs significantly different lectin binding profile few compared to cells. studied infectivity E. coli, Salmonella enterica, rotavirus, coron...

Gastrointestinal parasites are responsible for heavy economic and production lossesin bovines. The present study was conducted to determine the prevalence of gastrointestinal (GI)helminths bovine in different zones Rawalpindi district. Study area divided into fourdifferent zones. Feacal samples (n=670) were collected examined through coprologicalexamination techniques. Out samples, 158 found be...

Aim: The use of self-adhesive composites in dental treatment relatively a new concept. aim this study was to in-vitro evaluation cytotoxicity Vertise Flow and Nova Compo SF flowable on bovine pulp-derived cells. 
 Material method: Experimental test samples (2×5mm) were prepared. Bovine cells incubated MEM-Alpha (Gibco-Invitrogen). material be tested stored the culture medium for 24 hours t...

The binding of lomefloxacin to bovine lactoferrin (BLf) in a dilute aqueous solution was studied using fluorescence spectra. The binding constant (K) and the number of binding sites (n) were obtained by a fluorescence quenching method. The binding distance (r) and energy-transfer efficiency (E) between lomefloxacin and bovine lactoferrin were also obtained according to the mechanism of Foörster...

In the course of the study on the hemoglobin contained in newborn bovine blood, two major and five minor components which are specific to newborn bovine hemoglobin were detected by the methods of agar-gel electrophoresis, cellulose-acetate membrane electrophoresis and column chromatography. These components were examined on their alkaline resistance , and the results showed that all the compone...
