Argentina has detected its first case of a British-identified coronavirus variant that appears to be more infectious, authorities said Saturday. The infection was discovered in a man who arrived from Britain in Argentina in late December without symptoms of the disease. Authorities “detected the variant of SARS-CoV-2 from the United Kingdom in a traveler,” science […]
A simple saliva test developed by QUT biomedical scientists has detected early throat cancer in a person who had no symptom and no clinical signs of cancer. In what is believed to be a world-first, the non-invasive test picked up HPV-DNA in a saliva sample from an infected healthy person. Persistent human papillomavirus (HPV) infection […]
The immune system must learn from early in life to tolerate bacteria that normally populate healthy skin, while still defending against more dangerous “bugs,” but how immune cells make this distinction has long been a mystery. In a study of young mice, UC San Francisco scientists found that an early-life window of immune tolerance available […]
An international group of researchers working with Erasmus University Medical Center (Erasmus MC) in the Netherlands determined that SkinVision—the first CE-marked skin cancer application based on extensive clinical trials—has a sensitivity of 95.1% in detecting the most common forms of skin cancer. The research published in the Journal of the European Academy of Dermatology and […]
Pioneering blood test can detect if breast cancer will return almost a YEAR before secondary tumours appear on hospital scans The pioneering ‘liquid biopsy’ is almost 80 per cent accurate, tests have found It analyses a patient’s blood for DNA fragments released by their own tumours Charities have praised the ‘extremely exciting’ results of the […]
Antimalarial drugs appear to follow a typical pattern, with early effectiveness eventually limited by the emergence of drug resistance. A report in the Journal of Molecular Diagnostics describes a new assay using whole blood that simplifies the genetic analysis of malarial parasites by completely eliminating processing steps. This provides rapid access to critical information associated […]
A new diagnostic tool has been developed by researchers at The University of Texas at Austin that can easily, quickly and cheaply identify whether a mosquito belongs to the species that carries dangerous diseases such as Zika virus, dengue, chikungunya or yellow fever. It can also determine whether the bug has come into contact with […]
Scientists at Scripps Research have developed a urine diagnostic to detect the parasitic worms that cause river blindness, also called onchocerciasis, a tropical disease that afflicts 18 to 120 million people worldwide. Described in the journal ACS Infectious Diseases, the new, non-invasive test may provide an inexpensive method of determining in real time whether a […]
