Managing Epidemic: Cost-effective HIV testing for India

Posted: 10 Jun 2013 06:29 AM PDT

Using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) International model, a sophisticated statistical tool, a colloborative study found that India's population could be tested for HIV. By testing every five years, the epidemic could be managed and the testing could be expanded to high risk groups. The study model projects the dollar cost per year of extended lifespan by testing the general population.

How do you feed 9 billion people?

An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.

Women Can Be Screened Years Later than Men with “Virtual Colonoscopy”

A new study has found that women can be screened for colorectal cancer at least five to 10 years later than men when undergoing an initial “virtual colonoscopy.” Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may help establish guidelines for the use of this screening technique, which is less invasive than a traditional colonoscopy.

Partial Livers from Deceased Donors Saving the Lives of Infants

New research reveals that transplantation of partial livers from deceased adult and teen donors has become less risky for infants and young children, helping to save these young lives. Findings published online in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, indicate that risk of organ failure and mortality from partial or split liver transplant was comparable to whole organ transplant in this pediatric population.

The Role of Arc in Homeostatic Scaling by Which Brain Cells Form Long-Term Memories

Scientist at UCSF have made a breakthrough discovery by pointing out the role of Arc protein in long-term memory formation. It has been long known that Arc protein helps in long-term memory but it is now found that Arc act as a master regulator through a process called homeostatic scaling. The synaptic connections are strengthened without overstimulation and there by learning is translated into long-term memories.
