UC Davis researchers discover how HIV turns food-poisoning into lethal infection

... HIV. In a 2006 study, she found that HIV continued to replicate in the gut mucosa and suppress immune function in patients being treated with antiretroviral ... between an individuals immune system and HIV is happening in the gut mucosa where there is massive destruction of immune cells, Dandekar said. ...

Skin-like tissue developed from human embryonic stem cells

... Tufts have harnessed the pluripotency of human embryonic stem cells (hESC) to generate complex, multilayer tissues that mimic human skin and the oral mucosa (the moist tissue that lines the inside of the mouth). The proof-of-concept study is published online in advance of print in Tissue Engineering Part ...

Nanotechnology holds promise for STD drug delivery

... found that the particles, loaded with the drug agent, moved effectively in two important ways, penetrating to reach cells below the surface of the mucosa and distributing throughout the vaginal, cervical, and uterine regions. Furthermore, the siRNAs stayed in the tissues for at least a week and ...

Breakthrough optical technology to assess colon cancer risk, accuracy

... was elevated 75.3 percent above control levels (comparable region from patients with no adenomas) at the adenoma site and persisted in the uninvolved mucosa (microscopically normal) area. Moreover, tissue sites located within 10 and 30 centimeters away from an adenoma also manifested a highly ...

Anti-herpes treatment reduces HIV levels in women infected with both viruses

... HSV-2 enhances the risk of HIV-1 acquisition by around three-fold2. HSV-2 infection may also increase HIV-1 infectiousness by disrupting the genital mucosa and increasing the levels of HIV in the genital tract3, allowing easier transmissibility of the virus. In addition, the HIV viral load in the blood ...
