Elderly emergency patients less likely to receive pain medication than middle-aged patients

A new study by the University of North Carolina Health Care found that elderly patients are less likely to receive pain medication in hospital emergency departments compared to middle-aged patients. The study suggests that physicians may be cautious about potential side effects in older adults, leading to a significant gap in pain mana...

Diseased hearts to heal themselves in future

Researchers identify oncostatin M as a key player in the self-healing powers of the heart, allowing damaged heart muscle cells to reversion and produce new cells. This discovery holds promise for treating heart disease, but further research is needed to pinpoint the precise window of application.

Take care with pain meds

Chronic opioid users have longer hospital stays, more post-surgical pain and complications, and are less likely to recover fully after knee replacement surgery. Researchers recommend strategies such as weaning patients off strong opioids prior to surgery to improve patient outcomes.

Flexible rack systems sort molecules

A new method has been developed to separate enantiomers, which are pairs of molecules with a mirror-inverted structure. The method uses porous molecular organic frameworks (MOFs) to sort molecules, allowing for rapid and efficient separation of enantiomers in pharmaceutical production.

Researchers closer to the super bug puzzle

A new study published in PLoS Pathogens reveals that Staphylococcus aureus can develop resistance to the last-line antibiotic vancomycin by acquiring a single mutation in its DNA. This discovery highlights the high adaptability of Staph and emphasizes the need to improve antibiotic treatment strategies for serious bacterial infections.

Scientists defuse the 'Vietnam time bomb'

An international team of scientists discovered how a bacterial pathogen kills cells by preventing protein synthesis, paving the way for novel therapies to combat melioidosis. The study, led by the University of Sheffield, used intense X-rays to solve the structure of a protein from Burkholderia pseudomallei.

Attention and awareness uncoupled

A recent study using functional magnetic resonance imaging has found that attention, rather than awareness, modulates the activity in the primary visual cortex. This suggests that these two mental processes may be dissociated and affect nerve cells differently. The findings have implications for philosophy and psychology.

Protein love triangle key to crowning bees queens?

A team of scientists at Arizona State University has made new discoveries about the role of insulin pathways and partner proteins in determining a honey bee's caste fate. They found that blocking certain proteins can force larvae to develop into workers, but also allowed them to develop into queens by providing hormone treatments.

First large-scale study of pain reveals risk factors

A comprehensive clinical assessment has been developed to identify individuals at risk of developing jaw pain disorders. The UB researchers found that people who develop jaw pain disorders exhibit specific characteristics, including more trauma to the jaw, limitations, and noises in the jaw, headaches, and generally worse medical status.

Citrus indica Tanaka - a progenitor species of cultivated Citrus

Researchers from North Eastern Hill University investigate the karyomorphological data of Citrus species, revealing that C. indica has an intermediate asymmetry index value, making it a true progenitor of cultivated Citrus. This study supports the classification of three true species of Citrus: C. grandis, C. reticulata, and C. medica.
