متن کاملStability Analysis of a Fractional Order Model of HIV virus and AIDS Infection in the Community
In this paper a non-linear model with fractional order is presented for analyzing and controlling the spread of HIV virus. Both the disease-free equilibrium and the endemic equilibrium are found and their stability is discussed. The basic reproduction number , which is a function of the constant parameters in the model, plays an essential role in the stability of the ...
متن کاملAIDS virus envelope spike structure.
The envelope (Env) spikes on HIV-1 and closely related SIV define the viral tropism, mediate the fusion process and are the prime target of the humoral response. Despite intensive efforts, Env has been slow to reveal its structural and functional secrets. Three gp120 subunits comprise the 'head' of Env and three gp41 subunits comprise the 'stalk' and other membrane-associated elements. The rece...
متن کاملNucleotide sequence of the AIDS virus, LAV.
The complete 9193-nucleotide sequence of the probable causative agent of AIDS, lymphadenopathy-associated virus (LAV), has been determined. The deduced genetic structure is unique: it shows, in addition to the retroviral gag, pol, and env genes, two novel open reading frames we call Q and F. Remarkably, Q is located between pol and env and F is half-encoded by the U3 element of the LTR. These d...

So many places in the world, especially countries in Asia, are poised to experience a r...
