The progression from HIV infection to AIDS and death from AIDS is more rapid in people living in developing countries than those living in the United States and Europe, according to researchers from the Johns Hopkins Bloomberg School of Public Health, the Armed Forces Research Institute of Medical Sciences and Chiang Mai University in Thailand. The researchers tracked the length of time between HIV infection and AIDS among young Thai men. They also studied the death rate of the men 5-7 years after their HIV infection, which was higher when compared to their counterparts in developed countries. The study, “The Natural History of HIV-1 Infection in Young Thai Men After Seroconversion” is published in the May 2004 issue of the Journal of Acquired Immune Deficiency Syndrome.
“The importance of this study is that it demonstrates the survival and progression rates of HIV/AIDS from the time of HIV infection in a developing country and documents that the progression is more rapid than in the U.S. and Europe,” said Kenrad E. Nelson, MD, corresponding author and a professor in the Department of Epidemiology.
The researchers evaluated 235 men, who seroconverted during their two years of military service in the Royal Thai Army from 1991 to 1995. All of the men were drafted at the age of 21. After five to seven years, 156 were alive, 77 had died and 2 could not be located. The five-year survival rate of the study participants was 82 percent.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
