(Press-News.org) About The Study: The findings of this systematic review and meta-analysis of 15 randomized clinical trials with an effective population size of 2,786 patients suggest that daily tooth brushing may be associated with significantly lower rates of hospital-acquired pneumonia, particularly in patients receiving mechanical ventilation, lower rates of intensive care unit (ICU) mortality, shorter duration of mechanical ventilation, and shorter ICU length of stay. Policies and programs encouraging more widespread and consistent toothbrushing are warranted.

Secret vulnerabilities of cancer’s ‘death star’ revealed
2023-12-18
Researchers at the Centre for Genomic Regulation in Barcelona, Spain, and the Wellcome Sanger Institute near Cambridge, UK, have comprehensively identified the allosteric control sites found in the protein KRAS. These are highly sought after targets for drug development, representing secret vulnerabilities which can be exploited to control the effects of one of the most important causes of cancer. The study presents the first complete control map for any protein and is published today (18 December) in the journal Nature.

Toronto study identifies new concepts for GLP-1 action in the brain, the 2023 Science magazine breakthrough of the year
2023-12-18
Research pioneer Dr. Daniel Drucker has much to be proud of, as the GLP-1-based diabetes drugs hailing from his early research are named 2023 breakthrough of the year by the Science Magazine.
Not only have millions of people with type 2 diabetes benefitted from GLP-1 agonists, but the drugs also produced wide-ranging health benefits beyond weight loss in two recent patient trials.
For years, GLP-1 agonists have been known to have a fortuitous side effect of improving metabolic health, but how this is regulated in the body remains unclear. Now Dr. ...
Coral atoll islands may outpace sea-level rise with local ecological restoration, scientists say
2023-12-18
Ecological restoration may save coral atoll islands from the rising seas of climate change, according to an international team of scientists, conservationists, and an indigenous leader.
While global carbon emission reduction is imperative, local measures could be the key to the islands outpacing sea levels, they argue today in the journal Trends in Ecology & Evolution.
“Far from being doomed, in their natural state most coral atoll islands could adapt to sea level rise”, says Dr Sebastian Steibl from the University of Auckland ...
NIH researchers create genetic atlas detailing early stages of zebrafish development
2023-12-18
Researchers at the National Institutes of Health have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types. These diverse cells become tissues and organs that form juvenile fish capable of swimming and looking for food. The findings are published in Developmental Cell.
“Perhaps surprisingly, tiny zebrafish provide us with significant insight ...
Unleashing canine travel: Hospitality and tourism sector urged to adapt to dog-friendly travel demands
2023-12-18
Estimated to be worth USD 50.1 billion by 2030, a Surrey team of researchers has uncovered the potential of the growing dog-friendly travel market. The Covid-19 pandemic drove an increase in UK household dog ownership, creating a need for tourism providers to adapt to accommodate these four-legged family members.
The Surrey team set out to understand why people travel with their dogs, how they feel about it, and what challenges they face doing so.
Lori Hoy, PhD Researcher and lead author of the study at the University of Surrey, said:
"Some reports suggest that the UK dog population stands at 11 million, with 29% of UK adults having a dog in their ...
More parallel ‘traffic' observed in human brains than in animals
2023-12-18
In a study comparing human brain communication networks with those of macaques and mice, EPFL researchers found that only the human brains transmitted information via multiple parallel pathways, yielding new insights into mammalian evolution.
When describing brain communication networks, EPFL senior postdoctoral researcher Alessandra Griffa likes to use travel metaphors. Brain signals are sent from a source to a target, establishing a polysynaptic pathway that intersects multiple brain regions “like a road with many stops along the way.”
She explains that structural brain ...
The role of oxidized tryptophan residues in repairing damaged photosystem II protein
2023-12-18
Photosynthesis refers to the fundamental biological process of the conversion of light energy into chemical energy by chlorophyll (a green pigment) containing plants. This seemingly routine process in plants sustains all the biological life and activities on Earth. First reaction of photosynthesis occurs at a site called photosystem II (PSII), present on the thylakoid membrane in the chloroplast where light energy is transferred to chlorophyll molecules. PSII is made up of a complex group of proteins, including the D1 and D2 reaction center proteins.
Light ...
Breaking the mold: Zarbio and Georgia State scientists unveil game-changing theory on Alzheimer's disease
2023-12-18
Despite affecting millions worldwide, Alzheimer's disease (AD) has long lacked effective treatments due to a fundamental inadequacy of our understanding of its etiology and pathogenesis. The absence of an integrative theory connecting the molecular origins of AD with disturbances at the organelle and cell levels, changes in relevant biomarkers, and population-level prevalence has hindered progress. Even though most scientists only hope that an integrative theory of AD will emerge soon, scientists from Zarbio and Georgia State University discovered sufficient data to formulate a framework for such a theory.
The molecular and cellular ...
Scientists collect aardvark poop to understand how the species is impacted by climate in Africa
2023-12-18
CORVALLIS, Ore. – In a first-of-its-kind study of aardvarks, Oregon State University researchers spent months in sub-Saharan Africa collecting poop from the animal and concluded that aridification of the landscape is isolating them, which they say could have implications for their long-term survival.
“Everyone had heard of aardvarks and they are considered very ecologically important but there has been little study of them,” said Clint Epps, a wildlife biologist at Oregon State. “We wanted to see if we could collect enough data to begin to understand them.”

Thalassemia screening in Thailand: Medical Sciences Dean advocates for elevated trust
2023-12-18
- Insights from Professor Sakorn Pornprasert, Dean, Faculty of Associated Medical Sciences at Chiang Mai University, on raising thalassemia awareness in Thailand.
Thalassemia, a genetic disorder affecting hemoglobin production, poses a significant public health challenge in Thailand, with a high prevalence and substantial healthcare costs. According to Thailand's Ministry of Public Health, approximately 18-24 million or 30-40 percent of the Thai population carries the thalassemia gene.
Professor Sakorn Pornprasert, Dean, Faculty of Associated Medical Sciences, Chiang Mai University, shared his views on BGI Genomics Global 2023 State of Thalassemia Awareness ...
