Altered blood flow in the brain may cause symptoms of Parkinson's disease

Patients who suffer from REM sleep behavior disorder have altered blood flow in the brain, which can lead to a lack of oxygen in the brain tissue. In the long term, this may cause symptoms of Parkinson's disease. This is shown by research from Aarhus University and Aarhus University Hospital.

Repurposed gout medication (probenecid) shows potent inhibition of SARS-CoV-2 replication

New research by a team of scientists in the USA describes the potential utility of a drug called probenecid, commonly used to treat gout, to treat this devastating viral illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative virus of COVID-19.

Are COVID-19-related complications in children explained by abnormal immune responses?

A common theme in reports on COVID-19 around the world has been the large number of children who have not been infected or shown signs of disease. However, though the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes less acute infection in this age group, it is associated with a severe immune-mediated multisystemic illness called multisystem inflammatory syndrome in children (MIS-C).

Toll-like receptor 2 (TLR2) detects the SARS-CoV-2 envelope protein and generates inflammatory cytokines

Researchers at St Jude Children’s Research Hospital found that toll-like receptor 2 detects the SARS-CoV-2 envelope protein-producing inflammatory cytokines.

Study: No major difference in mortality between patients treated with drug-coated and non-drug-coated devices

Peripheral artery disease (PAD), or blockages in the arteries outside of the heart, affects more than 200 million people worldwide and 12.5 million people in the United States. Patients with this circulatory disorder may develop severe leg pain or unhealing wounds that require a minimally invasive revascularization procedure to open the blood vessels to improve blood flow.

Dendritic cells can take a shortcut to reach the lymph nodes more quickly

In its response to pathogens and vaccines, our immune system relies on dendritic cells. These white blood cells patrol the body's tissues, collect components of pathogens and vaccines and transport them via lymphatic vessels to the nearest lymph node.

New technology tricks tumors to eliminate itself through the production of anti-cancer agents

Scientists at the University of Zurich have modified a common respiratory virus, called adenovirus, to act like a Trojan horse to deliver genes for cancer therapeutics directly into tumor cells. Unlike chemotherapy or radiotherapy, this approach does no harm to normal healthy cells.

A look at how coronavirus disease (COVID-19) affects Parkinson's

Earlier, herpes simplex virus (HSV), influenza virus A, measles virus, cytomegalovirus (CMV), and mumps virus have all been associated with after-effects of the virus that includes Parkinson's disease (PD). This list may now include SARS-CoV-2.

Study reveals acute immunologic changes in children with long COVID

Many reports are beginning to emerge on the ‘long COVID’ phenomenon. But a new study, released as a preprint on the medRxiv* server, describes, for the first time, immunologic changes observed in children with PASC.

New filling method to treat cerebral aneurysms

Cerebral aneurysms are malformations caused by abnormalities on the walls of blood vessels in the brain. When these blood vessels rupture, about 30% of the sufferers die on the spot, giving these the rightful label of 'ticking bombs in the head'.
