Whole blood transcriptomic analysis of beef cattle at arrival identifies potential predictive molecules and mechanisms that indicate animals that naturally resist bovine respiratory disease

Bacteriological and therapeutic studies on Mannheimia haemolytica and Pasteurella multocida in bovine respiratory disease at dairy cattle farms in Tehran

In this study, we performed a bacteriological investigation on bovine respiratory infections. Additionally, the study evaluates the efficacy of florfenicol 30 µg produced by Rooyan Darou Company (test group) as compared to a similar drug produced by Aboraihan Company (control group). Sampling was carried out on 30 calves at two farms with 30-55% incidence rate of respiratory disorders. Nasophar...

Hsp70 sequences indicate that choanoflagellates are closely related to animals

Over 130 years ago, James-Clark noted a remarkable structural similarity between the feeding cells of sponges (choanocytes) and a group of free-living protists, the choanoflagellates. Both cell types possess a single flagellum surrounded by a collar of fine tentacles. The similarity led to the hypothesis that sponges, and, by implication, other animals, evolved from choanoflagellate-like ancest...

Market Impacts of Reducing the Prevalence of Bovine Respiratory Disease in United States Beef Cattle Feedlots

Bovine respiratory disease (BRD) is a common endemic disease among North American feedlot cattle. BRD can lead to significant economic losses for individual beef cattle feedlot producers through mortality and morbidity. With promising new management and technology research that could reduce BRD prevalence, this study evaluates the potential impacts of a reduction of BRD in the US beef cattle fe...

Genetic Mutations that Cause Coronary Artery Disease

Phosphonated polyurethanes that resist calcification.

Cardiovascular implant mineralization involving bioprosthetic materials, such as glutaraldehyde cross linked porcine aortic valves or synthetic materials such as polyurethanes, is an important problem that frequently leads to clinical failure of bioprosthetic heart valves, and complicates long-term experimental artificial heart device implants. Novel, proprietary, calcification resistant polyet...
