Kaposi's Sarcoma- A Detailed Information

The trillions of the cells in the body grow normally, divide, and then die accordingly. Once adulthood is reached cells divide only to replace worn-out or dying cells or to repair injuries.

What happens to cells in cancer?Cancer starts when cells in a certain organ or part of the start to grow out of control. Cells become cancer cells because of damage to DNA. Different types of cancer can behave very differently – some may remain at one location while others spread rapidly to other major organs via blood stream or via lymphatic channels. (1-4) How does Kaposi's sarcoma develop?Kaposi's sarcoma is a cancer that develops from the cell lining the lymph or blood vessels. The cancer appears as red, purple, or brown raised tumors or spots over the skin. These lesions are usually non-symptomatic but may cause painful swelling in some areas like legs, groin or skin around the eyes. Kaposi's sarcoma may become life threatening when it affects major organ like lungs, liver, or the gastr…

Conditions of first sexual encounter can be indicators of future HIV risk and gender-based violence

Adolescent girls and young women in Mombasa, Kenya are more likely to experience Higher risks of HIV and gender-based violence when they are involved with sex work venues or have sexual experiences at a young age, suggests a study co-led by St. Michael's Hospital and the University of Manitoba in Canada.
Published in the Journal of Acquired Immune Deficiency Syndromes (JAIDS), the research suggests that the conditions of a first sexual encounter, such as a woman's age, the man's age, use of condoms, and whether or not the encounter is consensual can be indicators of future risk of HIV infection and gender-based violence.The research team found that adolescent girls and young women in Mombasa, Kenya, who are forced or coerced in their first sexual experience, are four to five times more likely to face ongoing gender-based violence throughout their lifetime. This research also showed that one in four participants experience gender-based violence after their first sexual exper…

Scientists took another step towards creating an HIV vaccine

The scientific group of Peter the Great St.Petersburg Polytechnic University headed by Professor Andrei Kozlov published the results of a study devoted to the search of solutions for creating the HIV vaccine
During two years, with the support of the Russian Science Foundation's grant, researchers studied features of transmitted variants of HIV-1 virus. This type of HIV transmission is most typical for Russian Federation. Within the framework of the project, scientists have studied blood samples of injecting drug users with acute or early stages of HIV infection. The transmission of only one viral variant was detected in 70% of cases. These data were obtained by the method of single genome analysis (SGA), which allows to analyze 20-30 single genomes. In addition, the scientific group used the next-generation sequencing approach (NGS), capable of analyzing up to 5000 genomes. Thus, scientists managed to establish that all viruses are the "descendants" of any one virus part…
