On January 17, 2014, 50 years after the first Surgeon General’s report on smoking and health, the Surgeon General will release The Health Consequences of Smoking—50 Years of Progress (1). The report will be released at a White House press conference at 9:30 a.m. Eastern on January 17, with a live webcast available at http://whitehouse.gov/live. The report will provide a retrospective of the pas...

The prevalence of renal disease is increasing in the HIV-infected population, likely reflecting increases in renal disease in the general population due to hypertension and diabetes, clustering of HIV cases in black Americans (who have higher frequency of renal risk factors), and toxicities of antiretroviral and other drugs taken by HIV-infected patients. Screening for renal function and regula...

The Internet and web technologies created a new and unprecedented environment to governments, businesses, educational institutions, and individuals enabling them to webcast any information using multimedia tools. University libraries are nowadays using web environment to provide high quality information for their users mostly in digital format. The purpose of this study is to investigate the un...

Computer mediated communication is rapidly assuming an integral role in the university education experience. This is especially true for auditorium-style classes, which may potentially include hundreds of students. In such classes, the instructor may seek a more efficient means of communicating. The two emerging audio-visual media distribution channels, podcast and webcast augment the existing ...

Issues of HIV infection in women include perinatal care to prevent mother-child transmission and screening for cervical dysplasia. Antiretroviral therapy has been very successful in reducing perinatal transmission rates. Ongoing issues in this setting include absense of relevant pharmacokinetics data for new drugs and formulations, implementation of new resistance testing guidelines, and recent...

Data supporting the efficacy of HIV postexposure prophylaxis (PEP) come largely from a small number of older studies and case reports in health care workers, studies of transmission from infected mothers to their infants, and animal studies. These data also provide support for the current recommendations regarding duration of PEP and the window of time within which PEP should be started. Althou...

The antiretroviral treatment goal in highly treatment-experienced patients is now suppression of viral replication to undetectable levels, a goal that can be achieved by strategic use of combinations that include newer antiretroviral drugs. Newer drugs in established classes that improve virologic response when added to optimized background therapy include the protease inhibitors darunavir and ...

Traditional ARQ-based reliable protocols for unicast (e.g., TCP) as well as multicast (e.g., Horus [24], RMTP [15], etc.) use sequential numbering of data units and detect losses from discontinuities in the sequence of received packets. The Application Level Framing (ALF) [7] model encourages application control over loss-detection and recovery. With sequence numbers, the application must expre...

In fact, we believe that much o...

Spontaneous and sustained ("elite," or aviremic) control of HIV infection (ie, maintaining HIV RNA to less than 50 copies/mL in the absence of therapy) appears to occur in approximately 1 in 300 HIV-infected persons, and represents a distinct phenotype among HIV-infected individuals. Through a recently established international collaboration called the HIV Controller Consortium, over 300 elite ...
