HANGZHOU -- Chinese scientists have come up with a new membrane material which can efficiently separate salt from water and has other water purification functions.A research program led by professor Zhang Lin with the Zhejiang University developed the membrane formed by nanoscale bubbles and tubes. The material allows water to permeate three to four times faster than traditional membrane for water purification.Zhang likened the function of the membranes to the interior of the mammalian intestine as it absorbs water and nutrition.Zhang expects the membranes to have a variety of applications in home water purification, industrial waste water treatment and desalination.The research is ready for commercialization.The study was published in Science magazine on Friday. silicone wristband usb flash driveclear silicone wristbandsbracelet maker rubbernew rubber band braceletscreate wristbands online
HONG KONG - A research team led by scientists of the University of Hong Kong (HKU) announced Thursday the invention of a universal antibody drug against HIV/AIDS that can "kill two birds with one stone."By engineering a tandem bi-specific broadly neutralizing antibody (bNAb), the team found that this novel antibody drug is universally effective not only against all genetically divergent global HIV-1 strains tested, but also promoting the elimination of latently infected cells in a humanized mouse model, the team announced at a press conference.The single gene-encoded tandem bNAb titled "BiIA-SG" strategically ambushes invading HIV-1 particles to protect CD4 positive T cells by attaching to host protein CD4. BiIA-SG not only displays a potent activity against all three panels of 124 genetically divergent global HIV-1 strains tested, but also prevents diverse live viral challenges completely in humanized mice.Moreover, gene transfer of BiIA-SG achieves pro-longed drug availability in vivo, leading to a promising efficacy of eliminating HIV-1 infected cells in humanized mice.With significantly improved breadth and potency, BiIA-SG will hopefully be the first "made in Hong Kong" anti-HIV-1 antibody drug for clinical development, the team said.The research team was led by scientists at AIDS Institute and Department of Microbiology of HKU's Li Ka Shing Faculty of Medicine. The new findings were published in the April issue of Journal of Clinical Investigation, one of the world's leading biomedical journals.
