Study tracks development of chimp brain and makes comparison to humans

In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, too. Baby chimpanzees don't show the same dramatic increase in the volume of prefrontal white matter in the brain that human infants do.

Researchers to develop new prostate cancer therapy

Prostate cancer that has become resistant to hormone treatment and that does not respond to radiation or chemotherapy requires new methods of treatment. By attacking stem cell-like cells in prostate cancer, researchers at Lund University are working on a project to develop a new treatment option.

Research team reports first genetic sequencing of urothelial carcinoma

In an article published online this week in Nature Genetics, a University of Colorado Cancer Center team in partnership with universities in China and Denmark reports the first genetic sequencing of urothelial (transitional) carcinoma, the most prevalent type of bladder cancer.

Insight into how molecular motor proteins save energy

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets moved around the cell, and when.

G-CSF therapy does not induce chromosomal instability in healthy stem cell donors

According to a study published in Blood, the Journal of the American Society of Hematology (ASH), researchers have reported that administration of granulocyte colony-stimulating factor (G-CSF), a drug that releases stem cells from the bone marrow into the blood, is unlikely to put healthy stem cell donors at risk for later development of abnormalities involving loss or gains of chromosomes that have been linked to hematologic disorders such as myelodysplastic syndromes (MDS) and acute myeloid leukemia.

MYCN amplification can serve as a favorable prognostic indicator for neuroblastoma

Neuroblastoma, a malignant tumor that primarily affects infants and young children, is a leading cause of death for children with cancer. When amplification of the MYCN oncogene is found in the tumor, it usually indicates an aggressive tumor with rapid progression of the disease and a poor outcome. Thus MYCN amplification has come to be used as a prognostic indicator.

NSAIDs like ibuprofen slow the spread of breast cancers

Published online on Aug. 7, 2011, the journal Nature Medicine reports that non-steroidal anti-inflammatory drugs including ibuprofen reduce the severity of postpartum breast cancers in animal models.

Endothelial progenitor cells may repair leaky blood-brain barrier

University of South Florida Department of Neurosurgery and Brain Repair faculty members have received a $2.6 million grant from the National Institutes of Health to investigate the potential for cells derived from human bone marrow to benefit post-stroke patients by repairing the blood-brain barrier.

La Jolla Institute's new RNAi Center to focus on genetics behind myriad diseases

A major Center that will propel scientific efforts to pinpoint the specific genes involved in causing immune diseases, cancer and other diseases will be opened today at the La Jolla Institute for Allergy & Immunology.

Researchers discover key reason why pyrazinamide shortens duration of TB therapy

Pyrazinamide has been used in combination with other drugs as a first-line treatment for people with tuberculosis (TB) since the 1950s, but exactly how the drug works has not been well understood.

NPL scientists mimick the ways viruses infect human cells and deliver genetic material

Scientists at the National Physical Laboratory (NPL) have mimicked the ways viruses infect human cells and deliver their genetic material. The research hopes to apply the approach to gene therapy - a therapeutic strategy to correct defective genes such as those that cause cancer.

Single engineered protein blocks two related angiogenic receptors

Cancer needs blood. In fact, some cancer medications work solely to slow or prevent cancer cells from creating new capillaries, choking off their much-needed blood and nutrient supply to halt the growth of tumors.

Blood test early in pregnancy to detect baby’s gender

While carrying the child, a mother's blood has cell-free fetal DNA floating around in it, and it's possible to use this to test for the baby's sex. In a meta-analysis that covered more, the test was found to be 95% efficient in guessing the sex of the fetus — and it works from as early as seven weeks. As the fetus and the placenta develop, the amount of DNA present in the mother increases, boosting the accuracy of the test, which hits its peak at 20 weeks.
