Vector Transmission Alone Fails to Explain the Potato Yellow Vein Virus Epidemic among Potato Crops in Colombia.

The potato yellow vein disease, caused by the potato yellow vein virus (PYVV), is a limiting potato disease in northern South America. The virus can be transmitted either by the greenhouse whitefly (GWF), (Westwood) (Hemiptera: Aleyrodidae), or through vegetative propagules, such as infected tubers. Recently, GWF populations have been spotlighted as one of the main drivers of PYVV re-emergence, and consequently, PYVV management has been predominantly directed toward vector control, which is heavily based on insecticide use.

Lactobacillus fermentum BR11 and fructo-oligosaccharide partially reduce jejunal inflammation in a model of intestinal mucositis in rats.

Although probiotics are beginning to enter mainstream medicine for disorders of the colon, their effects on the small bowel remain largely unexplored. We investigated the recently identified probiotic, Lactobacillus fermentum (L. fermentum) BR11 (BR11) and the prebiotic, fructo-oligosaccharide (FOS), both individually and in synbiotic combination, for their potential to alleviate intestinal mucositis.

Lyprinol only partially improves indicators of small intestinal integrity in a rat model of 5-fluorouracil-induced mucositis.

Background: Intestinal mucositis is a common and debilitating side-effect of chemotherapy, associated with severe small intestinal inflammation. Marine oils, such as Lyprinol, a lipid extract derived from New Zealand Green-lipped Mussels, rich in long-chain omega-3 polyunsaturated fatty acids (n-3 PUFA), have demonstrated therapeutic potential for the treatment of inflammatory conditions. We assessed the effects of Lyprinol on the severity of 5-fluorouracil (5-FU)-induced mucositis in female Dark Agouti rats.

Identification of a novel mutation in the enamalin gene in a family with autosomal-dominant amelogenesis imperfecta.

Amelogenesis imperfecta (AI) is a heterogeneous genetic disorder that affects the formation of the dental enamel matrix. Mutations in the enamelin (ENAM) gene have been found in patients with this disorder. The objective of this research was to identify the mutations reported in exons 4, 7 and 9 of the ENAM gene in a single Colombian family with autosomal-dominant AI and to establish the phenotype.
