SARS-CoV-2 infection demonstrated in a human lung bronchioalveolar tissue model

Heidelberg/Germany, 11 January 2021 – Development of an in vitro human-derived tissue model for studying virus infection and disease progression in the alveolar cells of the lungs responsible for oxygen and carbon dioxide exchange with the blood might enable the study of possible therapies for acute respiratory distress syndrome (ARDS) triggered by SARS-CoV-2. Researchers in […]

Large US study confirms COVID-19 complications: lung, kidney and cardiovascular issues

A large study of patients in the United States who contracted coronavirus disease 2019 (COVID-19) confirms many complications of the disease, according to new research in CMAJ (Canadian Medical Association Journal). “Understanding the full range of associated conditions can aid in prognosis, guide treatment decisions and better inform patients as to their actual risks for […]

Medicine-carriers made from human cells can cure lung infections

SPOKANE, Wash. – Scientists used human white blood cell membranes to carry two drugs, an antibiotic and an anti-inflammatory, directly to infected lungs in mice. The nano-sized drug delivery method developed at Washington State University successfully treated both the bacterial growth and inflammation in the mice’s lungs. The study, recently published in Communications Biology, shows […]

Cooking with wood may cause lung damage — ScienceDaily

Advanced imaging with CT shows that people who cook with biomass fuels like wood are at risk of suffering considerable damage to their lungs from breathing in dangerous concentrations of pollutants and bacterial toxins, according to a study being presented at the annual meeting of the Radiological Society of North America (RSNA). Approximately 3 billion […]

Teen contracts ‘hot tub lung’ from indoor swimming pool

Severe breathing difficulties sent a 17-year-old in Queensland, Australia, to the emergency room with “hot tub lung” — inflammation caused by inhaling microbes in steam, usually contracted from hot tubs.  But the teen picked up the lung infection not from a hot tub, but from his family’s humid indoor swimming pool, after they started using […]

Jänne New results from early clinical trials of a drug that targets a cancer-causing mutation in the KRAS gene have shown that it can shrink tumours and is well-tolerated by patients. In two presentations […]

Targeted inhibitor of mutated KRAS gene shows promise in lung, bowel, & other solid tumors

IMAGE: Pasi A. Jänne, MD, PhD view more  Credit: Dana-Farber Cancer Institute A novel agent that targets a mutated form of the KRAS gene – the most commonly altered oncogene in human cancers and one long considered “undruggable” – shrank tumors in most patients in a clinical trial with manageable side effects, researchers reported today at […]

ASTRO: Proton therapy for lung cancer may help reduce risk of heart diseases

PHILADEPHIA–Treating lung cancer patients with proton therapy may help reduce the risk of radiation-induced heart diseases, suggests a new study from Penn Medicine. In a retrospective trial of more than 200 patients, mini-strokes were significantly less common among patients who underwent proton therapy versus conventional photon-based radiation therapy. Proton therapy patients also experienced fewer heart […]
