| A new and devastating physiological disorder of Vitis vinifera cv. Merlot was recently reported, known as premature berry dehydration (PBD), which is characterized by plant growth reduction, induction of general senescence and pedicel necrosis in the fruit, causing significant reductions in vineyard production. The causes of this disease remain unclear and previous reports suggest that it may be associated with phloem disruption and water provision. For this reason, any factor causing phloem disturbances could cause an important change in the berry water status. As some micro-organisms have been reported to disrupt phloem flow, we analyzed the occurrence of phytoplasma and viruses in commercial vineyards presenting PBD. In this study, a phytoplasma was... |

| In horses, insulin resistance is associated with several comorbidities such as obesity, laminitis, colic and osteochondrosis. The multifactorial causes of insulin resistance in horses have been addressed, which include genetic and environmental factors. As a consequence of these factors, the cellular signaling pathways responsible for insulin synthesis, the glucose intake in target cells of peripheral tissues and other related processes (e.g., adipocytokine signaling pathways) are affected. In response to insulin, changes in gene expression occur, which are required for the integration of an entire network of metabolic and physiological responses in different organs. The peroxisome proliferator-activated receptors (PPARs) were the particular focus of... |
