HIV Detection Made Easier with Cellphone Technology

The management of human immunodeficiency virus 1 (HIV), an autoimmune disorder that cripples the immune system by attacking healthy cells, remains a major global health challenge in developing countries that lack infrastructure and trained medical professionals.

Investigators from Brigham and Women's Hospital have designed a portable and affordable mobile diagnostic tool, utilizing a cellphone and nanotechnology, with the ability to detect HIV viruses and monitor its management in resource-limited regions. The novel platform is described in a paper published recently in Nature Communications.

Hepatitis B Virus and its High Stability, Study

At room temperature, hepatitis B virus (HBV) remains contagious for several weeks and can even withstand temperatures of four degrees centigrade over the span of nine months. When applied properly, disinfectants are effective – but only undiluted. These are the results obtained by a German-Korean research team in a study using a novel HBV infection system in human liver cells.

Salmonella Resistant to Different Classes of Antibiotics, Study

Common bacteria that causes foodborne diseases are resistant to antibiotics, according to research that identified 39 genes responsible for this resistance. Brazil's Ministry of Health received reports of 11,524 outbreaks of foodborne diseases between 2000 and 2015, with 219,909 individuals falling sick and 167 dying from the diseases in question.

Bacteria caused most outbreaks of such illnesses, including diarrhea and gastroenteritis. The most frequent were Salmonella spp., With 31,700 cases diagnosed in the period (14.4% of the total), Staphylococcus aureus (7.4%), and Escherichia coli (6.1%).

COPD: For Treatment, Tailored Approaches for Deadly Lung Disease are Considered

Valerie Chang kept waking up breathless in the middle of the night. As a regular swimmer and non-smoker, she figured it was a fluke, a remnant of her childhood asthma, perhaps. But after a lung test, doctors told her that she had the chronic obstructive pulmonary disease (COPD); her lung function was only 30% and she had done irreversible damage to her lungs. Unfortunately, they said, there was nothing they could do to improve her lung function, and she would likely need a transplant in a year.

Novel Treatment Approach With Largest Parasitic Worm Genetic Study

The largest genomic study of parasitic worms to date has identified hundreds of thousands of new genes and predicted many new potential drug targets and drugs. The research could help scientists understand how these parasites invade us, evade the immune system and cause disease. Reported in Nature Genetics, the study could lead to new de-worming treatments to help prevent and treat the diseases caused by parasitic worms worldwide.
