Optical and electrically driven single-molecular Raman switch

A team of scientists has developed a single-molecular Raman switch that can be controlled using both electrically driven conformational switching and optical inputs. The study demonstrates the use of near-field-enhanced techniques to manipulate molecular states, enabling highly accurate methods for nano-scale systems.

New research in JNCCN suggests a simple and inexpensive option for reducing a major chemotherapy side-effect

New research suggests that vitamin D supplements can reduce the risk of peripheral neuropathy in patients undergoing paclitaxel treatment. The study found that patients with vitamin D deficiency were more likely to experience severe neuropathy, and that inducing vitamin D deficiency caused similar symptoms in a mice model study.

AGA does not endorse all patients stopping popular diabetes and weight loss drugs prior to endoscopy

The American Gastroenterological Association suggests a balanced approach when treating patients on GLP-1 RAs undergoing endoscopic procedures. AGA recommends proceeding with the procedure as planned for patients who followed standard pre-procedure fasting instructions and do not have symptoms suggesting retained gastric contents.

New issue of Advances in Dental Research offers a comprehensive analysis of aging and oral health research

The new issue of Advances in Dental Research analyzes the link between healthy aging and access to quality oral health services. Key research highlights include the potential role of periodontal microflora in Alzheimer's disease progression and the impact of loneliness on health.

Analysis of firearm-related suicide data reveals elevated risk in younger teens and in states with lax firearm laws

A new study found that age-related patterns in firearm-related suicide have remained stable over decades, except for accelerating rates in younger teens. States with less strict firearm laws experienced significantly higher firearm suicide rates compared to those with more strict gun laws.

A potential target for new anti-cancer agents

The study found that SPT5 plays an important role in the development of MYC-dependent tumors, with reduced levels leading to significant regression of tumors. The researchers suggest that SPT5 could be a potential target for pharmacological inhibitors to combat cancer.

Mouse model of gender-affirming testosterone treatment and fertility finds decrease in egg yield but not quality

A mouse model study found that testosterone treatment decreased egg yield without affecting quality, but outcomes improved with a washout period. This research provides evidence to inform fertility care for transgender and gender diverse people who wish to become parents.

Mountain goats seek snow to shake off insects

Researchers studied mountain goats' behavior in Glacier National Park, finding that ear flicks showed a strong correlation with the presence of snow. The lack of summer snow patches may increase their risk of local extirpation due to increased tick infestations.

Why a surprising discovery, warming seas and the demise of the ‘Meg’ may spell trouble for more and more sharks

A new study has found that a relatively ancient shark species, the smalltooth sand tiger, exhibits anatomic features suggesting regional endothermy. This discovery suggests there may be more warm-blooded sharks than previously believed, and potentially poses significant conservation implications for these species.

Long COVID in women may be linked to inflammation levels at peak of infection, new research suggests

A study of 144 Covid survivors found that women with elevated inflammatory biomarkers during the acute phase were more likely to experience lingering symptoms like fatigue, breathlessness, and sleep disturbance. This research sheds light on a potential link between inflammation and persistent Long Covid symptoms in women.

Software created from ‘building blocks’ could incorporate artificial intelligence, supporting medical staff with workflow and disease management, study finds

A new system of computer software building blocks, EASUL, has been developed to create digital tools that help medical staff prioritize patient care and workloads more effectively. The system was tested using historic data and consultations with clinical teams, and showed promising results in managing community-acquired pneumonia cases.

Obesity linked to neurodegeneration through insulin resistance

Researchers found that a high-sugar diet causes insulin resistance in the brain, reducing its ability to remove neuronal debris and increasing the risk of neurodegenerative diseases. This study provides insight into how obesity-inducing diets contribute to disease risk.

The climate crisis could trigger the outbreak of new and lethal infectious diseases

A team from IRB Barcelona identifies Candida orthopsilosis, a hybrid fungus, as a potential pathogen that could infect humans and cause disease. The study suggests that climate change may have facilitated the emergence of this new microorganism, which has already been linked to several outbreaks and fatalities.

The molecular basis of ventilator-induced diaphragm weakness

Mitochondrial fragmentation is a key mechanism underlying ventilator-induced diaphragm dysfunction (VIDD), leading to excessive reactive oxygen species production and calcium homeostasis impairment. Blocking mitochondrial fission at the initiation of mechanical ventilation with a molecule like P110 could potentially prevent VIDD.

Risk of dying in hospital from respiratory causes is higher in the summer than in the winter

A study published in The Lancet Regional Health - Europe found that ambient temperature is strongly associated with inpatient mortality from respiratory diseases, particularly during the warm season. The research suggests that high temperatures contribute to an increase in fatal hospital admissions, especially in Barcelona.
