UNLABELLED Many previous studies have shown that lesions of the peripheral vestibular system result in spatial memory deficits and electrophysiological dysfunction in the hippocampus. Given the importance of glutamate as a neurotransmitter in the hippocampus, it was predicted that bilateral vestibular deafferentation (BVD) would alter the expression of NMDA and AMPA receptors in this area of th...

Bovine viral diarrhea disease is one of the viral diseases in cattle that were reported 10-90 percent in many countries. The causative RNA virus is a member of the family Flaviviridae and the genus pestivirus which is antigenically closely related with the virus of BD in sheep. Cattle are the most sensitive species to virus and are considered the principal reservoir of BVD viruses. A large prop...

Outbreaks of diarrhoea associated with mucosal erosions of the mouth, tongue and digestive tract, clinically diagnosed as bovine virus diarrhoea-mucosal disease (BVD-MD), have been reported in Argentina and Brazil since the 1960's. However, primary isolation of the virus of BVD-MD is fairly recent, occurring in 1974 for Brazil, 1984 for Argentina, 1985 for Chile and 1981 for Colombia. In Argent...

BACKGROUND In 2008, a program to eradicate bovine virus diarrhea (BVD) in cattle in Switzerland was initiated. After targeted elimination of persistently infected animals that represent the main virus reservoir, the absence of BVD is surveilled serologically since 2012. In view of steadily decreasing pestivirus seroprevalence in the cattle population, the susceptibility for (re-) infection by b...

Nine healthy pregnant does free from BVD neutralizing antibodies were I/V and I/P inoculated with two cytopathic strains of BVD virus (NADL-camel) at about 65 days of gestation. In NADL strain of BVDV group, abortion occurred in 3 out of 5 virus inoculated does on 7, 17 and 21 days post inoculation (PI) . The mean serum progesterone values of pregnant does significantly decreased on days 7(P<0....

BACKGROUND Calf output is a key element in determining the profitability of a suckler beef enterprise. Infectious agents such as Bovine Virus Diarrhoea (BVD) virus, colostrum management and parasitic challenge can all affect calf output. Prior to the national BVD eradication programme, there was little published information on either the prevalence or effect of BVD in Irish beef herds. There is...

Following several clinical cases of suspected bovine virus diarrhoea (BVD) on three Namibian cattle farms, a serological survey was conducted on bovine, ovine, caprine and wild ruminant sera originating from different regions of the country. Neutralizing antibodies to BVD virus (BVDV) were detected in 58% of 1,014 cattle sera, 14% of 618 sheep sera and 4.6% of 1,118 goat sera. Sera from seven o...

Locating the Optic Disc (OD) is of critical importance in a retinal analysis system. This paper presents a fast algorithm for the automatic localization of OD in digital fundus retinal images. OD localization follows the Blood Vessel Detection (BVD). A morphology based approach is proposed for BVD. OD is localized by exploiting the property that it is a bright region and the density of blood ve...

In this paper, we present a novel hybrid nonlinear explicit-compact scheme for shock-capturing based on boundary variation diminishing (BVD) reconstruction. our approach, combine non-dissipative sixth-order central compact interpolation and fifth-order monotonicity preserving (MP5) through the BVD algorithm. For smooth solution, reconstruction chooses highest order possible interpolation, which...
