UCLA cancer researchers develop quality measures for colorectal cancer surgery

A new set of quality indicators has been created to evaluate the quality of care received by patients undergoing colorectal cancer surgery. The guidelines cover aspects of surgical care, including pre-operative evaluation and post-operative management, to provide a valuable tool for improving patient outcomes.

Nearly unbreakable

Researchers at Max Planck Institute found that bone stretches more than its fibers and mineral composition, allowing it to sustain large strains without breaking. The hierarchical structure of bone leads to a hierarchical deformation, with soft layers absorbing most of the strain, protecting the mineral phase from excessive loads.

Quality care assessment examines surgical quality for colorectal cancer patients

Researchers identified 142 candidate indicators of quality care for colorectal cancer surgery, including surgical credentials, preoperative evaluation, and postoperative management. The expert panel rated 92 indicators as valid, suggesting these can be used to measure care quality and create improvement programs.

Jefferson scientists find blood vessel-building protein halts blood vessels from forming in cancer

Researchers at Thomas Jefferson University have found that the protein fragment endorepellin blocks both skin and lung cancer tumors from progressing in animal models by preventing their ability to recruit new blood vessels. Endorepellin has surprisingly powerful effects on halting a cancer tumor's ability to move about and spread.

Adolescent arrest history influences risk of acquiring HIV

Researchers found that adolescents with a history of arrest were more likely to engage in unprotected sex acts and use substances during sex. This increased risk was attributed to higher rates of substance abuse, mental health issues, and unfavorable attitudes towards risky behavior.

A new target for painkillers

Researchers found a new approach to treating chronic and debilitating neuropathic pain by blocking the alpha9alpha10 nicotinic acetylcholine receptor. The study suggests a previously unrecognized molecular mechanism for treating this condition, which affects hundreds of millions of people worldwide.

Malaria poses additional risks for first-time mothers

Research suggests that women in their first pregnancy with placental malaria are three times more likely to develop preeclampsia. High levels of sVEGFR1 and VEGF were found in these mothers, indicating a conflict between the mother's and fetus's immune responses.

Children's Hospital Oakland's new maternal diet study

A new study by Children's Hospital Oakland Research Institute shows that a mother's diet during pregnancy can affect the health of her grandchildren by changing the behavior of a specific gene. The research involved mice fed with or without nutritional supplements, which resulted in changes to their coat color and obesity levels.

Healthier kids just the click of a remote away

A recent study by the University of Toronto found a statistically significant link between TV viewing and physical inactivity in Canadian adolescents. The study, which tracked over 7,982 participants aged 12-19, revealed that more hours spent watching TV were associated with less energy expended on physical activity.

Peer and family support tops needs of young adult cancer survivors

A study published in CANCER reveals that adolescent and young adult cancer patients value social connections with peers as a high priority, contrary to physician beliefs. Researchers found that meeting other young people who share a common experience helps address concerns such as coping with uncertainty and body changes.

What's the difference between mice and men?

Researchers used fruit flies to study the genetic basis of species differences, finding that small changes in control regions of genes can result in morphological differences and potentially even the creation of a new species. The study highlights the importance of regulatory sequences in gene evolution.

SimCity for real

A team of researchers is using data from the 2001 census to build a model of the UK population, which will be used to test the consequences of different demographic trends and policy decisions. The model can be projected into the future to explore how different scenarios may play out.

Inexpensive test detects H5N1 infections quickly and accurately

Scientists have developed an inexpensive gene chip test that can detect H5N1 infections with high accuracy, providing a significant advantage over existing tests. The MChip has the potential to revolutionize laboratory testing for influenza, enabling rapid and accurate identification of flu viruses, including avian influenza H5N1.

Nanoscale microscope sheds first light on gene repair

Researchers have used a new type of light microscope to visualize the distribution of H2AX proteins in the cell nucleus, revealing clusters that direct DNA repair after damage. This discovery provides new insights into the complex process of gene repair and its relationship with other nuclear components.
