Loss of Dickopf-1 restores neurogenesis and memory in animal model

Loss of the molecule Dickopf-1 in the hippocampus in older animals increases neurogenesis, research shows.

Wnt-induced Lgr5 expression marks stem cell production in the liver

For decades scientists around the world have attempted to regenerate primary liver cells known as hepatocytes because of their numerous biomedical applications, including hepatitis research, drug metabolism and toxicity studies, as well as transplantation for cirrhosis and other chronic liver conditions. But no lab in the world has been successful in identifying and growing liver stem cells in culture -- using any available technique - until now.

Researchers improve NanoVelcro device to better grab cancer cells as blood passes by them

Researchers at UCLA report that they have refined a method they previously developed for capturing and analyzing cancer cells that break away from patients' tumors and circulate in the blood. With the improvements to their device, which uses a Velcro-like nanoscale technology, they can now detect and isolate single cancer cells from patient blood samples for analysis.

Study finds major risk factor behind increased risk of adverse outcomes in IVF pregnancies

Massachusetts General Hospital (MGH) researchers have identified what may be a major factor behind the increased risk of two adverse outcomes in pregnancies conceived through in vitro fertilization (IVF).

Recombinant Newcastle disease virus kills all kinds of prostate cancer cells

A recombinant Newcastle disease virus kills all kinds of prostate cancer cells, including hormone resistant cells, but leaves normal cells unscathed, according to a paper published online ahead of print in the Journal of Virology.

Cleveland Clinic receives $1.97M NIMH grant for innovative autism research

The National Institute of Mental Health (NIMH) has awarded $1.97 million for innovative autism research to Bruce Trapp, Ph.D., Chairman of Neurosciences at Cleveland Clinic's Lerner Research Institute.

DHA supplementation during pregnancy reduces very low birth weight and early preterm delivery

University of Kansas researchers have found that the infants of mothers who were given 600 milligrams of the omega-3 fatty acid DHA during pregnancy weighed more at birth and were less likely to be very low birth weight and born before 34 weeks gestation than infants of mothers who were given a placebo. This result greatly strengthens the case for using the dietary supplement during pregnancy.

Experts analyse biological function of Shewanella-like protein phosphatase

Experts have disabled a unique member of the signalling proteins which are essential for the development of the malaria parasite. They have produced a mutant lackingthe ancient bacterial Shewanella-like protein phosphatase known as SHLP1 (pronounced shelph). This mutant is unable to complete its complex life cycle and is arrested in its development in the mosquito.

Insight into cellular operations that give extraordinary staying power to S. mansoni

From the point of view of its ultimate (human) host, the parasitic flatworm Schistosoma mansoni has a gruesome way of life. It hatches in feces-tainted water, grows into a larva in the body of a snail and then burrows through human skin to take up residence in the veins. Once there, it grows into an adult, mates and, if it's female, starts laying eggs. It can remain in the body for decades.

HDAC-mediated mechanisms play critical role in regulating lung repair and regeneration

Lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) are on the rise, according to the American Lung Association and the National Institutes of Health.

Survey finds 65% of Missouri salons would allow pre-teens to use tanning beds

A survey of tanning salon operators in Missouri shows that 65 percent would allow children as young as 10 to 12 years old to use tanning beds. That's despite evidence that any tanning bed use increases the risk of all skin cancers, including melanoma, the deadliest form of skin cancer, later in life.

Early lymphoid progenitors thrive in an osteoblastic niche: Study

The Children's Medical Center Research Institute at UT Southwestern has deepened the understanding of the environment within bone marrow that nurtures stem cells, this time identifying the biological setting for specialized blood-forming cells that produce the infection-fighting white blood cells known as T cells and B cells.

Distinct bone marrow niches can nurture different types of blood stem cells

In research that could one day improve the success of stem cell transplants and chemotherapy, scientists have found that distinct niches exist in bone marrow to nurture different types of blood stem cells.

Better representation of elderly patients in phase III trials can improve evidence-based treatment

The median age of patients diagnosed with advanced non-small-cell lung cancer (NSCLC) has steadily increased over the recent years and is presently 70 years. Despite this, the elderly are significantly underrepresented in clinical trials.

Mechanisms of HPV-associated tumor spread under scrutiny

In patients with human papillomavirus-associated tonsillar carcinoma, second tumors in the contralateral tonsil are typically caused by the same viral variant, a case series indicates.

Kaposi’s sarcoma risk factors revealed

Scientists have uncovered an intriguing relationship between the risk for Kaposi’s sarcoma, smoking, and the use of highly active antiretroviral therapy.
