New bacterium discovered -- related to cause of trench fever

... Koehler recalls. They can cause extremely painful lesions and tumors of blood vessels on the skin of immunocompromised patients. But when I saw this patient, this type of infection had never been seen at UCSF, and the bacterium causing the infection was unknown. Koehlers group went on to discover that t...

Agonized death throes probable cause of open-mouthed, head-back pose of many dino fossils

...losaurus, a T rex-like animal, that displayed bone lesions suggestive of a bacterial infection that also can lead to meningitis, a disease that can produce opithotonus. The authors point out that their explanation of the opisthotonic posture in dinosaurs and other animals provides a way to assess the role pl...

Lancet study shows gene therapy for Parkinson's disease is safe and some patients benefit

... the disease. Decades ago, surgeons began to make lesions in parts of the brain involved in the disease, which lessened symptoms. Fetal stem cell surgery was pioneered in Parkinson's patients. And in the past decade, the deep brain stimulation has worked in as many as 70 percent of patients who have opted f...

...xiety. In this new combined approach, any suspect lesions can be studied with MRS, with no need for an invasive biopsy. Spectroscopy can be used to test for any number of chemical compounds. In this case, it is measuring the amount of choline in suspect lesions. Elevated levels of choline are a strong indic...

Here we see both infection and malignancy going on in the presence of THC, offering some serious concerns about the safety of THC a...

Link identified between Alzheimer's disease and glaucoma

... beta-amyloid, which causes the so-called "plaque" lesions in the brains of Alzheimer's patients, also leads to nerve cell death in the retina. The research is published online today in the journal Proceedings of the National Academy of Sciences of the USA. "We've seen for the first time that there is a cl...
