NEW OCCURRENCES OF PHYTOTELMATA-INHABITING MOSQUITOES SPECIES IN NORTHWESTERN ARGENTINA.

The potential risk areas for emerging or reemerging diseases are determined by the presence, abundance, and distribution of mosquitoes. Here new records and geographical distribution extension of mosquito species in phytotelmata are updated for Argentina. We report for the first time Toxorhynchites bambusicola in Aechmea distichantha in Salta and Tucumán provinces, in the northwest region of Argentina.

Virus-induced vesicular acidification enhances HIV immune evasion.

To inhibit endocytic entry of some viruses, cells promote acidification of endosomes by expressing the short isoform of human nuclear receptor 7 (NCOA7) which increases activity of vacuolar ATPase (V-ATPase). While we found that HIV-1 infection of primary T cells led to acidification of endosomes, NCOA7 levels were only marginally affected. Contrastingly, levels of the 50 kDa form of the sodium/hydrogen exchanger 6 (NHE6) were greatly reduced.

Neuroprotective Effect of Curcumin-Metavanadate in the Hippocampus of Aged Rats.

Brain aging is a multifactorial process that includes a reduction in the biological and metabolic activity of individuals. Oxidative stress and inflammatory processes are characteristic of brain aging. Given the current problems, the need arises to implement new therapeutic approaches.

sp. nov., a member of the isolated from badland surfaces in the Red Desert, Wyoming, USA.

A novel Gram-stain-positive, black-pigmented bacterium, designated as WL48A , was isolated from the surface of badland sedimentary rock in the Red Desert of Wyoming and characterized using a polyphasic taxonomic approach. Good growth occurred at 28-32 °C, pH 7-9, and NaCl less than 1% (w/v). Colonies, growing well on International Streptomyces Project media (ISP) 3 and ISP 7, were black and adhering to the agar.
