New case series section in European Urology

A new case series in European Urology introduces a purely intrafascial approach for robot-assisted laparoscopic prostatectomy, aiming to avoid damage to critical structures. The study reports promising results with no perioperative major complications, but highlights the need for well-designed studies to evaluate its advantages.

An IRCM researcher pinpoints the cellular mechanism responsible for modulating the permeability of blood vessels

A new cellular mechanism has been identified for modulating blood vessel permeability, which could have a significant impact on the treatment of cancerous tumours. Nitrosylation of beta-catenin protein by nitric oxide increases vascular permeability, potentially leading to the blockage of tumour growth.

Trusting people make better lie detectors

Researchers discovered that trusting people are more accurate at detecting lies and make better hiring decisions. They were also less likely to be deceived themselves. High trust individuals formed a more accurate impression of interviewees and chose honest candidates over dishonest ones.

Potential novel genetic pathway for alcoholism

Researchers have identified a novel mutation in a mouse gene that may contribute to the genetic roots of alcoholism. The mutation, called Lightweight, affects sensitivity to alcohol and voluntarily consumed more alcohol by mutant mice. Further studies are needed to determine if this pathway is relevant to humans.

Use of specialist retrieval teams to transport sick children to pediatric intensive care units is associated with reduced mortality

A study published in The Lancet found that specialist retrieval teams significantly reduce mortality rates among children transferred to pediatric intensive care units. Children admitted from other hospitals had better outcomes and lower mortality rates when transferred by specialist teams compared to non-specialist transfers.

Menstrual cramps may alter brain structure

A new study found that menstrual cramps can cause alterations in the brain's gray matter, even when pain is not present. Researchers discovered abnormal changes in specific brain areas involved in pain transmission and regulation, suggesting that the adolescent brain may be vulnerable to menstrual pain.

Seeing melanoma

A new imaging technique, combining photoacoustic tomography and a smart contrast agent, produces three-dimensional images of melanoma with high accuracy. This enables surgeons to remove only the malignant tissue while maintaining clean margins.

Energy storage system deals with sudden draws on the grid

Researchers at the University of Leeds have developed an integrated system that stores excess energy and uses it to supply electricity during peak demand. This innovative system cuts greenhouse gas emissions by reducing nitrogen oxide emissions and capturing carbon dioxide in solid form for storage.

Using bone marrow stem cells to treat critically ill patients on verge of respiratory failure

A team led by Drs. Michael A. Matthay and Jae W. Lee found that bone marrow stem cells secreted a protein that restored the lung barrier, preventing fluid and other elements from entering the lungs. The study suggests that this therapy may be a viable option for preventing respiratory failure in critically ill patients.

Research links huntingtin to neurogenesis

New research reveals that abnormal huntingtin protein plays a crucial role in neurogenesis, challenging previous understanding of its function in adult neurons. The study demonstrates htt's involvement in cell division and neurogenesis, shedding light on the pathogenic mechanisms underlying Huntington's disease.

Advance toward earlier detection of melanoma

Scientists have developed a substance to enhance visibility of skin cancer cells during scans, potentially leading to earlier detection and improved survival rates for patients with melanoma. The new technique uses photoacoustic tomography and a bioconjugated gold nanoparticle agent that targets skin cancer cells.

Best way to pour champagne? 'Down the side' wins first scientific test

A scientific study reveals that pouring champagne down the side of an angled glass preserves more carbon dioxide than pouring straight down the middle. The researchers also found that chilling champagne to 39 degrees Fahrenheit reduces carbon dioxide loss, making 'down-the-side' a winning method for preserving champagne's taste and fizz.
