Aspirin is linked with increased risk of heart failure
- Details
- Category: Research
Aspirin use is associated with a 26% raised risk of heart failure in people with at least one predisposing factor for the condition. That’s the finding of a study published today in ESC Heart Failure, a journal of the European Society of Cardiology (ESC). Predisposing factors included smoking, obesity, high blood pressure, high cholesterol, diabetes, and cardiovascular disease.
Exposure to harmless coronaviruses boosts SARS-CoV-2 immunity
- Details
- Category: Research
The population's immunity to SARS-CoV-2, achieved either through infection or vaccination, is crucial to overcome the COVID-19 pandemic. A team of researchers led by the University of Zurich (UZH) has now discovered another component that contributes to SARS-CoV-2 immunity - previous antibody responses to other, harmless coronaviruses.
Repurposing a familiar drug for COVID-19
- Details
- Category: Research
For the past year and a half, the COVID-19 pandemic has continued to engulf the globe, fueled in part by novel variants and the uneven distribution of vaccines. Every day, hundreds of thousands of new COVID-19 cases and thousands of new deaths are still being reported worldwide, creating a need for drugs that can combat the disease caused by SARS-CoV-2.
Scientists identify new types of a blood cancer and potential targeted treatments
- Details
- Category: Research
Mount Sinai researchers have developed a new model that uses DNA and RNA sequencing data from hundreds of patients to identify specific genes and genetic alterations responsible for never-before-defined subtypes of a blood cancer called multiple myeloma. They also identified potential targeted treatments based on the findings, as reported in Science Advances in November.
Coffee and tea drinking may be associated with reduced rates of stroke and dementia
- Details
- Category: Research
Drinking coffee or tea may be associated with a lower risk of stroke and dementia, according to a study of healthy individuals aged 50-74 publishing November 16th in the open-access journal PLOS Medicine. Drinking coffee was also associated with a lower risk of post-stroke dementia.
'Dancing molecules' successfully repair severe spinal cord injuries
- Details
- Category: Research
Northwestern University researchers have developed a new injectable therapy that harnesses “dancing molecules” to reverse paralysis and repair tissue after severe spinal cord injuries.
In a new study, researchers administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk.
New target for COVID-19 vaccines identified
- Details
- Category: Research
Next generation vaccines for COVID-19 should aim to induce an immune response against 'replication proteins', essential for the very earliest stages of the viral cycle, concludes new research carried out by UCL scientists.
By designing vaccines that activate immune memory cells, known as T cells, to attack infected cells expressing this part of the virus’s internal machinery, it may be possible to eliminate SARS-CoV-2 at the very outset, thereby helping stop its spread.
