Extracellular metallothionein as a therapeutic target in the early progression of type 1 diabetes.

Type 1 diabetes (T1D) is characterized by lymphocyte infiltration into the pancreatic islets of Langerhans, leading to the destruction of insulin-producing beta cells and uncontrolled hyperglycemia. In the nonobese diabetic (NOD) murine model of T1D, the onset of this infiltration starts several weeks before glucose dysregulation and overt diabetes. Recruitment of immune cells to the islets is mediated by several chemotactic cytokines, including CXCL10, while other cytokines, including SDF-1α, can confer protective effects.

Effect of octenidine hydrochloride on planktonic cells and biofilms of Listeria monocytogenes.

Listeria monocytogenes is a food-borne pathogen capable of forming biofilms and persisting in food processing environments for extended periods of time, thereby potentially contaminating foods. The efficacy of octenidine hydrochloride (OH) for inactivating planktonic cells and preformed biofilms of L. monocytogenes was investigated at 37, 21, 8, and 4 degrees C in the presence and absence of organic matter (rehydrated nonfat dry milk).

Minimising inter-laboratory variation when constructing a unified molecular database of plant varieties in an allogamous crop.

The construction of large-scale databases of molecular profiles of plant varieties for variety identification and diversity analyses is of considerable interest. When varieties of an allogamous species such as oilseed rape are analysed and described using molecular markers such as microsatellites, care is needed to represent the variety in a meaningful yet useful way. It is possible to characterise such heterogeneous genotypes by analysing bulked samples comprising more than one individual seed or plant, but this approach may result in complex microsatellite profiles.
