Cell research signals cancer hope

A team of researchers at the University of Manchester has discovered that cell communication signals can be more complicated than previously thought. This breakthrough should help scientists better investigate what happens when these signals go wrong, potentially leading to new cancer treatments.

Poverty in Northern Ireland

A new ESRC report reveals that a higher proportion of families in Northern Ireland are living below the poverty line compared to Britain or the Republic of Ireland. The report also highlights severe child poverty in Northern Ireland, with many households struggling to access basic necessities like heating and clothing.

PGA on a tour under the skin

S. epidermidis produces poly-gamma-glutamate (PGA) to protect itself from innate host defenses during infection. The findings suggest PGA as a promising target for drug development to combat related illnesses.

Optimal treatment of carpal tunnel syndrome

A one-year study found that local steroid injection is as effective as surgery in alleviating CTS symptoms, with improved results in the short term. The study suggested a preference for conservative therapies over surgery.

Public interest advocates question NIH Enhanced Access policy

The NIH Enhanced Access policy lacks a definitive deadline for making research results available, putting grant recipients in a difficult position. Advocates urge the agency to report on progress toward full taxpayer access using metrics such as the proportion of deposited articles and lag time between publication and availability.

Fleshing out the genome

A new method assigns biological functions to unknown genes, enabling genome comparison, by integrating experimental and computational analyses. This approach identifies functional proteins in 97% of hypothetical genes and provides a framework for ranking their precision and confidence.

Pro-inflammatory protein contributes to Crohn's disease according to UCSD School of Medicine study

A study published in Science identified interleukin-1Beta (IL-1â) as a major cause of severe inflammation in mouse models of Crohn's disease, which is a chronic inflammatory bowel disease affecting over 500,000 Americans. High levels of IL-1â were found in mice with mutant NOD2, a genetic defect linked to 50% of Crohn's cases.

New neurons born in adult rat cortex

Scientists at NIMH have discovered newborn neurons in adult rat cortex that communicate via GABA, suggesting potential new treatments for depression and anxiety. The discovery adds to the scientific debate over adult neurogenesis and has implications for understanding brain disorders such as Alzheimer's and schizophrenia.

New component of the 'brakes' on nerve regeneration found

Researchers have found a new protein, TAJ/TROY, that acts as part of the receptor complex in neurons responding to growth-inhibitory molecules. This discovery may provide insights into designing therapeutic strategies to block myelin inhibition and promote regeneration of spinal cord or brain tissue after injury.

Key trigger of opioid withdrawal symptoms found

A study led by Elena Bagley and Macdonald Christie found that a transporter molecule for the neurotransmitter GABA is responsible for opioid withdrawal symptoms. Inhibiting this molecule or protein kinase A eliminates hyperexcitability in PAG neurons.

MRI 'excellent choice' for overcoming challenges of diagnosing pregnant women with abdominal pain

A study published in the American Journal of Roentgenology found that MRI is an excellent choice for diagnosing pregnant women with abdominal pain due to its high accuracy and safety from radiation. The study analyzed 29 patients and diagnosed 14 different causes of abdominal pain, including appendicitis and ovarian cysts.
