Do altered gut microbes affect risk of attention-deficit/hyperactivity disorder?

2023-04-05
(Press-News.org) New research published in the Journal of Child Psychology and Psychiatry suggests that the microbial composition of the gut may affect a child’s susceptibility to attention-deficit/hyperactivity disorder (ADHD).

The human gastrointestinal tract hosts a large population of microorganisms such as bacteria, viruses, and fungi. When investigators compared fecal samples from 35 children with ADHD and 35 healthy controls, samples from children with ADHD had higher levels of certain species of fungi and lower levels of other species. 

In experiments with cells grown in the lab, one species in abundance in samples from children with ADHD—called Candida albicans—increased the permeability of cells that line the intestine. This could create a “leaky gut” that allows bacteria into the bloodstream, possibly resulting in inflammation throughout the body and brain.

“The human body is home to a complex and diverse microbial ecosystem, and findings from this study suggest that dysbiosis of the fungal mycobiome in ADHD can influence patient health,” the authors wrote.

Can a drug used to treat liver disease help prevent SARS-CoV-2 infections and lessen COVID-19 severity?

2023-04-05
SARS-CoV-2, the virus that causes COVID-19, attaches to a cellular receptor called angiotensin-converting enzyme 2 (ACE2), and activation of the farnesoid X receptor increases ACE2 expression. New research published in the Journal of Internal Medicine suggests that a drug that inhibits the farnesoid X receptor and is used to treat liver disease may decrease SARS-CoV-2 infections and reduce the severity of COVID-19. The study ran from March 2020 to February 2022 and included 3,214 patients with liver disease, half of whom were taking the drug, called ursodeoxycholic acid (UDCA). ...

Can some snakes do cartwheels to escape or startle predators?

2023-04-05
In research published in Biotropica, investigators report that the Dwarf Reed Snake (Pseudorabdion longiceps) performs cartwheels when threatened. This is the first time such an active rolling motion has been documented in snakes, with images and a detailed description. The Dwarf Reed Snake is a nocturnal, small snake that lives in regions of Southeast Asia. Typical defense mechanisms that small snakes use against predators include fleeing, camouflage, coloration, odors, death-feigning, and intimidation. ...

Can phototherapy improve cognitive function in patients with dementia?

2023-04-05
In an analysis of published clinical trials, investigators found that phototherapy—or exposure to sessions of bright light—may be a promising non-pharmacological intervention for lessening symptoms of dementia. The analysis in Brain and Behavior included 12 randomized clinical trials. Results indicated that phototherapy improved cognitive function in patients with dementia, but it did not affect symptoms of depression or sleep quality. “Further well-designed studies are needed to explore the most effective clinical implementation ...

Could a novel small molecule slow or reverse the effects of Duchenne muscular dystrophy?

2023-04-05
In a new study published in The FASEB Journal, investigators demonstrated the potential of a molecule that may help overcome some of the devastating symptoms of Duchenne muscular dystrophy (DMD), the most common life-limiting congenital neuromuscular disorder. The agent promotes the activity of AMP-activated protein kinase (AMPK), an important fuel-sensing enzyme that is present in all mammalian cells. Previous research has shown that stimulating AMPK can mitigate the dystrophy—or wasting—of muscles, but AMPK activators have failed to reach the clinic due to either their lack of potency or toxic off-target effects. In ...

CycPeptMPDB: A database aimed at promoting drug design using cyclic peptides

CycPeptMPDB: A database aimed at promoting drug design using cyclic peptides
2023-04-05
CycPeptMPDB, a novel database—created by Tokyo Tech researchers—focused on the membrane permeability of cyclic peptides, could accelerate the development of drugs based on these promising compounds. This database was created by gathering published information on thousands of cyclic peptides and organizing it neatly in an online-accessible platform. Thanks to its search and visualization capabilities, CycPeptMPDB could pave the way to new computational and machine learning methods for screening and designing drugs with cyclic peptides. One of the ...

Brain injury toolkit helps support domestic violence survivors

2023-04-05
COLUMBUS, Ohio – A new approach to trauma-informed care developed by domestic violence survivor advocates and researchers at The Ohio State University has been found in a new study to improve support organizations’ care for survivors by better recognizing brain injury and addressing its often long-lasting repercussions. The study appears in the Journal of Head Trauma and Rehabilitation. CARE is the first trauma-informed approach that considers brain injury in the complex set of circumstances to be addressed and accommodated in order ...

A cold-specialized icefish species underwent major genetic changes as it migrated to temperate waters, new study finds

2023-04-05
Many animals have evolved to tolerate extreme environments, including being able to survive crushing pressures of ocean trenches, unforgiving heat of deserts, and limited oxygen high in the mountains. These animals are often highly specialized to live in these specific environments, limiting them from moving to new locations. Yet, there are rare examples of species that once lived in harsh environments but have since colonized more temperate settings. Angel Rivera-Colón, a former graduate student now postdoc in the lab of Julian Catchen (CIS/GNDP), an associate professor in the department ...

Bacterial signaling across biofilm affected by surface structure

2023-04-05
Similar to how cells within human tissues communicate and function together as a whole, bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria form after they reach a certain density, and are used to help the colonies scavenge food, as well as defend against threats, like antibiotics.  “QS helps them to build infrastructure around them, like a city,” ...

Researchers discover new class of ribosomal peptide with hemolytic activity

Researchers discover new class of ribosomal peptide with hemolytic activity
2023-04-05
Living organisms produce a myriad of natural products which can be used in modern medicine and therapeutics. Bacteria and other microbes have become the main source for natural products, including a growing family called ribosomally synthesized and post-translationally modified peptides, or RiPPs. The labs of Douglas Mitchell (MMG), John and Margaret Witt Professor of Chemistry, and Huimin Zhao (CABBI/BSD/GSE/MMG), Steven L. Miller Chair of Chemical and Biomolecular Engineering, at the University of Illinois Urbana-Champaign have been working in tandem to identify and analyze new RiPPs that could be good candidates ...
