Coreceptor-Based Hematopoietic Stem Cell Gene Therapy for HIV Disease.

Combination antiretroviral therapy (cART) has significantly reduced the mortality rate and morbidity, and has increased the life expectancy of the human immunodeficiency virus (HIV) infected patients. However, the current cART is incapable of eradicating viruses from the human body, and HIV remains one of the most notorious viruses mankind has ever faced. HIV-1 enters target cells through the binding of gp120 viral protein to a CD4 receptor and then to a coreceptor, C-C chemokine receptor 5 (CCR5) or C-X-C chemokine receptor type 4 (CXCR4).

[Vertical change of cladoceran ephippial densities in the sediments of Lake Nanyi and its correlation with the nutrients].

We examined the vertical variations of cladoceran ephippia in the sediments (1-28 cm) of Lake Nanyi. Nine cladoceran ephippia (Daphnia similoides sinensis, Daphnia galeata, Daphnia pulex, Ceriodaphnia sp., Moina micrura, Bosmina sp.
