Viral Communications Hacking: Boosts Leishmania Infections

Leishmania are ancient eukaryotes that have retained the exosome pathway through evolution. Leishmania RNA virus 1 (LRV1)-infected Leishmania species are associated with a particularly aggressive mucocutaneous disease triggered in response to the double-stranded RNA (dsRNA) virus. However, it is unclear how LRV1 is exposed to the mammalian host cells. In higher eukaryotes, some viruses are known to utilize the host…

Ultrasonography Of Calcaneus Offers Comparable results

In a study that could lead to wide use of inexpensive ultrasound screenings for osteoporosis, researchers found data from ultrasonography of the calcaneus (heel bone) was equal to data gathered using dual-energy x-ray absorptiometry (DXA), which is considered the gold standard for assessing bone health. The findings could lead to lower costs and increased screening…

Model To Study A Lethal Complication

Adult secondary hemophagocytic lymphohistiocytosis (sHLH) is a fulminant hyperinflammatory syndrome with mortality exceeding 80% in spite of state-of-the-art medical care. The pathogenesis of sHLH, unlike primary HLH, which is primarily genetic, is poorly understood. Here we describe a model of sHLH that recapitulates many aspects of human sHLH. Pathogenesis are unknown We found that the…

Folate Levels Decrease Significantly When Solar Radiation Is Higher

For the first time, researchers from the University of Malaga have evidenced this relationship, confirming that ultraviolet radiation affects directly in proportion to folate in blood. Thus, this team of scientists have determined a seasonal risk threshold among patients with folate deficiency, since; according to this study; folate levels decrease significantly in those months when…

To Prevent, Treat Alcoholism: New Target Identified

;Alcohol use disorder (AUD) is a chronic condition with devastating health and socioeconomic effects. Still, pharmacotherapies to treat AUD are scarce. In a prior study aimed at identifying novel AUD therapeutic targets, we investigated the DNA methylome of the nucleus accumbens core (NAcc) of rhesus macaques after chronic alcohol use. Developing medication to prevent and…
