Growth factor triggers growth of new blood vessels in the heart

The study found that activating hedgehog signals in adult mouse hearts increased blood vessel density, offering an alternative to invasive procedures. The researchers believe a drug treatment targeting hedgehog signaling could provide substantial benefit to patients with ischemic heart disease and myocardial infarctions.

Potentially 1000s of 'brain drain' scientists would help home countries if system to do so created

A study of 60 life science researchers and entrepreneurs from developing countries found a lack of communication and coordination between diaspora members and their home countries. The researchers call for the establishment of mechanisms such as Diaspora Business Initiatives and National Science Corps to facilitate partnerships and col...

Sport should not be used to promote unhealthy behaviour

The 2012 London Olympics will require significant public investment and feature corporate sponsors like McDonald's and Coca-Cola, raising concerns about the promotion of unhealthy behaviors. Dr. Jeff Collin argues that these associations are highly questionable given the significance of obesity as a health problem.

Nilotinib appears to help chronic myelogenous leukemia patients when standard care fails

A phase I clinical trial reveals nilotinib has a relatively favorable safety profile and demonstrates activity against drug-resistant CML, with notable improvements in chronic phase CML patients. However, the agent shows less activity in acute lymphoblastic leukemia patients and may require careful monitoring for cardiac events.

Where the brain organizes actions

Broca's area plays a crucial role in organizing actions and processing hierarchical structures, according to researchers Etienne Koechlin and Thomas Jubault. Their experiments found that this executive function is distinct from the organization of temporal sequences of actions.

RBP4 predicts type 2 diabetes

Researchers found that elevated RBP4 levels are closely associated with insulin resistance, metabolic syndrome, and increased risk of developing type 2 diabetes. Exercise therapy can lower RBP4 levels and improve insulin sensitivity in individuals at risk of diabetes.

ESF task force for clean solar energy

The ESF task force identifies three research avenues to generate clean fuels from solar radiation: extending photovoltaic technology, constructing biomimetic devices, and tuning natural systems. These efforts aim to develop sustainable energy supply, reduce human ecological footprint, and mitigate climate change.

Manual vs device-assisted CPR

The LBD-CPR device's effectiveness is influenced by its use details, including patient population selection and deployment timing. Out-of-hospital cardiac arrests claim over 1,000 daily US lives.
