New chemical compound demonstrates potential in nerve regeneration
2023-05-24
Research led by UCL, in partnership with the MRC Laboratory of Molecular Biology (MRC LMB) and AstraZeneca, has identified a new compound that can stimulate nerve regeneration after injury, as well as protect cardiac tissue from the sort of damage seen in heart attack.
The study, published in Nature, identified a chemical compound, named ‘1938’, that activates the PI3K signalling pathway, and is involved in cell growth. Results from this early research showed the compound increased neuron growth in nerve cells, and in animal models, it reduced heart tissue damage after major trauma and regenerated lost motor function in a model of nerve injury.

New research finds dramatic increase in illegal ketamine seized by authorities, sparking concern about potential dangers of rising recreational use
2023-05-24
A new analysis led by NYU Grossman School of Medicine and the National Drug Early Warning System (NDEWS) at the University of Florida found a 349 percent rise in seizures of illicit ketamine by drug enforcement throughout the United States from 2017 through 2022.
The study findings suggest that rising use of ketamine, a short-acting dissociative anesthetic commonly prescribed off-label to treat chronic pain and depression, can increase the likelihood that people who use recreationally or who use inadvertently may encounter an adulterated and potentially harmful version of the drug. The study publishes online May 24 in JAMA Psychiatry.

COVID-19 and risk for mental disorders among adults in Denmark
2023-05-24
About The Study: In this Danish nationwide cohort study, overall risk of new-onset mental disorders in SARS-CoV-2–positive individuals did not exceed the risk among individuals with negative test results (except for those age 70 and older). However, when hospitalized, patients with COVID-19 had markedly increased risk compared with the general population, but comparable to risk among patients hospitalized for non–COVID-19 infections. Future studies should include even longer follow-up time and preferentially ...
Association of community vulnerability and state gun laws with firearm deaths in children and adolescents
2023-05-24
About The Study: In this study including 5,813 youths ages 10 to 19 who died of an assault-related firearm injury, socially vulnerable communities in the U.S. experienced a disproportionate number of assault-related firearm deaths among youths. Although stricter gun laws were associated with lower death rates in all communities, these gun laws did not equalize the consequences on a relative scale, and disadvantaged communities remained disproportionately impacted. While legislation is necessary, it may not be sufficient to solve the problem of assault-related firearm deaths among children and adolescents.

Fewer suicides among boys in regions with more bipolar diagnoses
2023-05-24
Bipolar disorder underlies roughly five percent of all suicides among young people. Previous studies also show that there is often a long delay between the onset of bipolarism and its correct diagnosis and treatment. Researchers at Karolinska Institutet now show that fewer boys commit suicide in Swedish regions where bipolar diagnoses are more common. The study, which is published in JAMA Psychiatry, could contribute to more proactive care for reducing the number of suicides.
“Bipolar disorder is often more distressing for people who develop it early in life and is one of the psychiatric disorders most associated with suicide risk,” says ...

In resistance training, focusing on load or number of repetitions leads to same muscle growth
2023-05-24
Which kind of resistance training promotes more muscle growth: low load with many repetitions or high load with fewer repetitions? According to a study conducted at the State University of Campinas (UNICAMP) in São Paulo state, Brazil, it makes no difference.
The study lasted eight weeks and involved 18 volunteers in two different training protocols. One group performed high-load (HL) exercises with fewer repetitions, while the other did low-load (LL) exercises with more repetitions. Muscle mass was measured in the first and last exercise sessions. A comparison of the two groups did not show any difference in muscle growth or metabolic stress, measured in an ...
Why do some long Covid patients continue to have difficulty exercising?
2023-05-24
While some patients recover from the effects of SARS-CoV-2 infection, others have experienced the aftereffects of COVID-19 long after the initial infection. One of these long COVID symptoms is reduced exercise capacity. But questions remain about the mechanisms underlying why some COVID patients continue to experience diminished exercise capacity while others recover without this condition.
In a study recently published in the Journal of Infectious Diseases, a team of researchers from UC San Francisco found that lower than expected exercise capacity was common ...

CHOP researchers comprehensively assess the safety of using your head in youth soccer
2023-05-24
Philadelphia, May 24, 2023 – Repeatedly heading a soccer ball has been previously associated with negative long-term brain health for professional players. However, in a new study from researchers at the Minds Matter Concussion Program at Children’s Hospital of Philadelphia (CHOP), a small number of repeated soccer headers equivalent to a throw-in did not cause immediate neurophysiological deficits for teens, suggesting that limited soccer heading exposure in youth sports may not result in irreversible harm if players are properly trained.

Use of AI: Placebo effect increases risk-taking
2023-05-24
Human augmentation technologies refer to technological aids that enhance human abilities. They include things like exoskeletons, but also augmented reality headsets. A study at the Chair of Human-Centered Ubiquitous Media at LMU has now shown that users have high expectations of the effects of these technologies. As soon as they believe that AI is enhancing their cognitive abilities, they increase their risk-taking. And they do this independently of whether the AI is actually assisting them.
“The hype around AI applications affects the expectations of users. This can lead to riskier behavior,” says Steeven Villa, doctoral researcher ...
