Immune mechanisms, resistance genes, and their roles in the prevention of mastitis in dairy cows.

Mastitis is one of the most important diseases of the mammary gland. The increased incidence of this disease in cows is due to the breeding of dairy cattle for higher yields, which is accompanied by an increased susceptibility to mastitis. Therefore, the difficulty involved with preventing this disease has increased.

Comparative Analysis of Selected Chemical Parameters of , from Cascara to Silverskin.

Nowadays, there is an increased interest in coffee derivatives (green beans, roasted beans, and coffee by-products (Cascara and Silverskin)) due to their particular chemical composition. This study aimed to compare the content of dry matter, total fat, fatty acids, and fiber (ADF, NDF) of coffee by-products (Cascara and Silverskin) and coffee beans (green and roasted under different conditions). Coffee beans and their by-products were obtained from 100% coffee cherries from Panama by dry process.

Impact of Nutrients on the Hoof Health in Cattle.

Lameness is currently one of the most important and economically demanding diseases in cattle. It is manifested in a change in locomotion that is associated with lesions, especially the pelvic limbs. The disease of the hoof is painful, affecting the welfare of dairy cows.

Umbilical cord blood cells CD133+/CD133- cultivation in neural proliferation media differentiates towards neural cell lineages.

Background And Aims: Umbilical cord blood (UCB) has been identified as a good source of hematopoietic and nonhematopoietic stem cells that can be easily isolated. In the present study we investigated the possibility of whether stem cells in mononuclear UCB grown under defined conditions can produce progeny with neural phenotype.

Methods: A combination of antigen-driven magnetic cell sorting (MACs) method and defined culture conditions specific for cells of neural lineages were used for isolation, expansion and differentiation of CD133+/- cells from UCB.

Repetitive intrathecal catheter delivery of bone marrow mesenchymal stromal cells improves functional recovery in a rat model of contusive spinal cord injury.

Transplantation of bone marrow mesenchymal stromal cells (MSCs) has been shown to improve the functional recovery in various models of spinal cord injury (SCI). However, the issues of the optimal dose, timing, and route of MSC application are crucial factors in achieving beneficial therapeutic outcomes. The objective of this study was to standardize the intrathecal (IT) catheter delivery of rat MSCs after SCI in adult rats.

Response of ependymal progenitors to spinal cord injury or enhanced physical activity in adult rat.

Ependymal cells (EC) in the spinal cord central canal (CC) are believed to be responsible for the postnatal neurogenesis following pathological or stimulatory conditions. In this study, we have analyzed the proliferation of the CC ependymal progenitors in adult rats processed to compression SCI or enhanced physical activity. To label dividing cells, a single daily injection of Bromo-deoxyuridine (BrdU) was administered over a 14-day-survival period.
