In hypothyroid patients, altered microvascular structure and function may affect mood and cognitive function. We hypothesized that adult male hypothyroid rats will have significantly lower forebrain blood vessel densities (BVD) than euthyroid rats and that treatment with 3,5-diiothyroprionic acid (DITPA) (a thyroid hormone analog) or thyroxine (T(4)) will normalize BVDs. The euthyroid group rec...

BACKGROUND Lymphatic vessels are major routes for metastasis in head and neck squamous cell carcinoma (HNSCC), but lymphatic endothelial cells (LECs) are difficult to recognize in tumor histological sections. D2-40 stains podoplanin, a molecule expressed in LECs, however, the potential prognostic usefulness of this molecule is not completely understood in HNSCC. We aimed to investigate the valu...

A mysterious disease affecting calves, named bovine neonatal pancytopenia (BNP), emerged in 2007 in several European countries. Epidemiological studies revealed a connection between BNP and vaccination with an inactivated vaccine against bovine virus diarrhea (BVD). Alloantibodies reacting with blood leukocytes of calves were detected in serum and colostrum of dams, which have given birth to ca...

Endemic diseases of cattle, such as bovine viral diarrhea, have significant impact on production efficiency of food of animal origin with consequences for animal welfare and climate change reduction targets. Many modeling studies focus on the local scale, examining the on-farm dynamics of this infectious disease. However, insight into prevalence and control across a network of farms ultimately ...

Hereditary or acquired cerebellar hypoplasia (CH) is commonly diagnosed in Holstein, Guernsey, Shorthorn and Jersey cattle. Bovine viral diarrhea (BVD) has been associated to acquired CH due to viral infection during the second trimester of pregnancy. Stricken calf usually shows ataxia, hypermetria, opisthotonus, intentional tremor and wide-based stance when in standing position. Three newborn ...

We recently showed that mTOR attenuation blocks progression and abrogates established cognitive deficits in Alzheimer's disease (AD) mouse models. These outcomes were associated with the restoration of cerebral blood flow (CBF) and brain vascular density (BVD) resulting from relief of mTOR inhibition of NO release. Recent reports suggested a role of mTOR in atherosclerosis. Because mTOR drives ...

Antigenic and genomic relationships between five pairs of non-cytopathic and cytopathic bovine viral diarrhoea (BVD) viruses isolated from cattle with mucosal disease were examined. Antigenic similarity was evaluated by studying the binding characteristics of 10 monoclonal antibodies (MAbs) directed against the gp53 BVD virus glycoprotein. The MAb binding match between members of the same virus...

Two hundred and thirty-nine cattle from Gauteng Province in South Africa were tested for various pathogens causing reproductive diseases includingbovine viral diarrhoea/mucosal disease (BVD/MD) virus, infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) virus, Neospora caninum and Brucella abortus usingvarious tests. For BVD/MD virus, 49.37% tested positive, 74.47% for...

Available diagnostic tests for bovine viral diarrhea virus (BVDV) and the persistently infected (PI) BVDV carrier state are reviewed and presented in table format. The test of choice will depend on the age of animal being tested, whether the animal is alive or dead and whether the veterinarian is only interested in identifying PI animals or if transiently infected (TI) animals are also of inter...

CCTV cameras installed for continuous surveillance generate enormous amounts of data daily, forging the term Big Video Data (BVD). The active practice BVD includes intelligent and activity recognition, among other challenging tasks. To efficiently address these tasks, computer vision research community has provided monitoring systems, recognition methods, many computationally complex solutions ...
