Russian scientists have synthesized chemical compounds that can stop the degeneration of neurons in Alzheimer's, Parkinson's, and other severe brain pathologies. These substances can provide a breakthrough in the treatment of neurodegenerative pathologies. New molecules of pyrrolyl- and indolylazine classes activate intracellular mechanisms to combat one of the main causes of "aged" brain diseases - an excess of so-called amyloid structures that accumulate in the human brain with age. The essence of the study was published in the European Journal of Medicinal Chemistry.
Tokyo, Japan - Chronic obstructive pulmonary disease (COPD) causes illness and death worldwide. It is characterized by destruction of the walls of tiny air sacs in the lungs, known as emphysema, and a decline in lung function. Little has been known about the mechanisms by which it begins to develop. But now, researchers from Japan have found a protein that promotes the development of the early stages of emphysema, with the potential to be a therapeutic target.
Research led by the University of Southampton into the uptake of the COVID-19 vaccine in Ghana, West Africa has concluded that vaccine hesitancy has seen a small, but significant increase over the last three months. This research is in collaboration with youth-led not-for-profit organisation PACKS Africa.
In the latest survey of 1,295 unvaccinated people, in May/June 2021, willingness to be vaccinated remained relatively high at just over 71.4 percent. However, this figure is down 11 percent on results from March 2021 when an earlier version of the same survey was conducted.
Some COVID-19 patients who experience acute respiratory failure respond by significantly increasing their respiratory effort - breathing faster and more deeply
There is concern among some doctors that this level of respiratory effort can lead to further damage to these patients' lungs.
Oncotarget published "Caspase-11 and AIM2 inflammasome are involved in smoking-induced COPD and lung adenocarcinoma" which reported that cigarette smoking is the leading risk factor for COPD and lung cancer establishment.
Epidemiologically, COPD patients are 6.35 times more likely to develop lung cancer.
Researchers are using computer models to simulate COVID-19 infections on a cellular level - the basic structural level of the human body.
The models allow for virtual trials of drugs and vaccines, opening the possibility of pre-assessment for drug and vaccine efficacy against the virus.
The research team at the University of Waterloo includes Anita Layton, professor of applied mathematics and Canada 150 Research Chair in mathematical biology and medicine, and Mehrshad Sadria, an applied mathematics PhD student.
Reno, Nev. (July 15, 2021) - Wildfire smoke may greatly increase susceptibility to SARS-CoV-2, the virus that causes COVID-19, according to new research from the Center for Genomic Medicine at the Desert Research Institute (DRI), Washoe County Health District (WCHD), and Renown Health (Renown) in Reno, Nev.
A new study by Vanderbilt University Medical Center researchers of more the 400,000 Medicare patients taking medications for insomnia found that the risk of death is increased when either benzodiazepines or "z-drugs" are taken with opioids.
Highlights
The sodium-glucose co-transporter 2 inhibitor dapagliflozin reduced kidney, cardiovascular, and mortality risks in patients with advanced chronic kidney disease, similar to benefits seen in individuals with normal or moderately impaired kidney function.
Rates of serious side effects were similar in patients with advanced chronic kidney disease who received dapagliflozin or placebo.
All cancers fall into just two categories, according to new research from scientists at Sinai Health, in findings that could provide a new strategy for treating the most aggressive and untreatable forms of the disease.
In new research out this month in Cancer Cell, scientists at the Lunenfeld-Tanenbaum Research Institute (LTRI), part of Sinai Health, divide all cancers into two groups, based on the presence or absence of a protein called the Yes-associated protein, or YAP.
A UC San Francisco study has found that the antibiotic azithromycin was no more effective than a placebo in preventing symptoms of COVID-19 among non-hospitalized patients, and may increase their chance of hospitalization, despite widespread prescription of the antibiotic for the disease.
"These findings do not support the routine use of azithromycin for outpatient SARS-CoV-2 infection," said lead author Catherine E. Oldenburg, ScD, MPH, an assistant professor with the UCSF Proctor Foundation. SARS-CoV-2 is the virus that causes COVID-19.
The COVID-19 pandemic knocked many women off schedule for important health appointments, a new study finds, and many didn't get back on schedule even after clinics reopened. The effect may have been greatest in areas where such care is already likely falling behind experts' recommendations.
Vaccine negativity and reluctance didn't just emerge during the COVID-19 pandemic. In a recent study published in the Disaster Medicine and Public Health Preparedness journal, authors from Loyola University Maryland and Johns Hopkins Bloomberg School of Public Health explored the appearance of negative dominance - a concept in which negative messages outweigh positive, solution-oriented messages in audiences' perceptions - in the context of COVID-19 vaccine-related information and activity online.
New research from the RIKEN Center for Brain Science (CBS) in Japan shows that a deficit in histone methylation could lead to the development of autism spectrum disorders (ASD). A human variant of the SUV39H2 gene led researchers to examine its absence in mice. Published in Molecular Psychiatry, the study found that when absent, adult mice exhibited cognitive inflexibility similar to what occurs in autism, and embryonic mice showed misregulated expression of genes related to brain development. These findings represent the first direct link between the SUV39H2 gene and ASD.
