Paper describes new method for studying bacterial infection of orthopedic implants

A research team, co-headed by Dr. Woo Lee and Dr. Hongjun Wang of Stevens Institute of Technology, has published a paper describing a new method that generates three-dimensional tissue models for studying bacterial infection of orthopedic implants. Dr. Joung-Hyun Lee of Stevens, and Dr. Jeffrey Kaplan of the New Jersey Dental School, are co-authors of the research.

Researchers create device to find ways to improve commonly used treatment for 'water on the brain'

Van Andel Research Institute (VARI) scientists participated in a study with researchers from the University of Utah that could help find ways to improve shunt systems used to treat the neurological disorder hydrocephalus, or "water on the brain," the leading cause of brain surgery for children in the United States. Researchers studied the shunt systems under a variety of conditions by creating a bioreactor that mimics the environment inside patients.

Cranberry juice prevents urinary tract infections: Study

Scientists reported new evidence on the effectiveness of that old folk remedy cranberry juice for urinary tract infections at the ACS' 240th National Meeting. "A number of controlled clinical trials these are carefully designed and conducted scientific studies done in humans have concluded that cranberry juice really is effective for preventing urinary tract infections," said Terri Anne Camesano, Ph.D., who led the study.

Researchers create artificial human ovary to yield infertility treatments for cancer patients

Researchers at Brown University and Women & Infants Hospital have invented the first artificial human ovary, an advance that provides a potentially powerful new means for conducting fertility research and could also yield infertility treatments for cancer patients. The team has already used the lab-grown organ to mature human eggs.

WPI researchers: Cranberry juice cocktail blocks strain of S. aureus

Expanding their scope of study on the mechanisms of bacterial infection, researchers at Worcester Polytechnic Institute have reported the surprise finding from a small clinical study that cranberry juice cocktail blocked a strain of Staphylococcus aureus (S. aureus) from beginning the process of infection.

Researchers identify molecule to slow down dysfunctional immune response in hemorrhagic shock

Researchers have isolated a molecule, small enough to be used as a drug, that can shut down a dysfunctional immune response that causes deadly hemorrhagic shock, results in delayed death of heart attack patients, promotes rejection of transplanted organs and destroys joints in patients with rheumatoid arthritis, according to a paper published in Molecular Immunology.

Today's opinions: Rep. Ryan's plan to aid Medicare; The burden on health law supporters in Va.; Evaluating Medicare actuary's estimates

Only in Washington could the government raid one entitlement program to finance a brand-new one and still claim that deficits have been reduced and entitlements have been reformed (Rep. Paul Ryan, 8/13).

Study shows link between fructose and pancreatic cancer proliferation

Pancreatic cancers use the sugar fructose, very common in the Western diet, to activate a key cellular pathway that drives cell division, helping the cancer to grow more quickly, a study by researchers at UCLA's Jonsson Comprehensive Cancer Center has found.

Cancer cells utilize fructose as an alternative to glucose for fueling growth: Study

A study published in the August issue of Cancer Research has resulted in several premature and potentially misleading conclusions when it comes to fructose and its effect on pancreatic tumor cells. Unfortunately, the media covering this story, and even the authors, have been too quick to extrapolate the results of laboratory research on pure fructose to real-world conditions, which is not appropriate or helpful to consumers.

Individual cells react differently to complex signals: Study

Using new technology that allows scientists to monitor how individual cells react in the complex system of cell signaling, Stanford University researchers have uncovered a much larger spectrum of differences between each cell than ever seen before.

Studying cells in 3-D could help develop drugs to prevent cancer from spreading: Researchers

Showing movies in 3-D has produced a box-office bonanza in recent months. Could viewing cell behavior in three dimensions lead to important advances in cancer research? A new study led by Johns Hopkins University engineers indicates it may happen. Looking at cells in 3-D, the team members concluded, yields more accurate information that could help develop drugs to prevent cancer's spread.

UCLA research sheds light on how brain tells time

The ability to tell time is fundamental to how humans interact with each other and the world. Timing plays an important role, for example, in our ability to recognize speech patterns and to create music. Patterns are an essential part of timing. The human brain easily learns patterns, allowing us to recognize familiar patterns of shapes, like faces, and timed patterns, like the rhythm of a song. But exactly how the brain keeps time and learns patterns remains a mystery.

Tel Aviv University researchers invent new tool to control risk of runaway stem cells

Stem cell research holds promise for improving the quality of human life ― especially embryonic stem cells, which can potentially develop into any tissue in the human body. However, basic scientific problems still remain unresolved -- but Tel Aviv University researchers are leading the way to inventive solutions.

Researchers decipher how mast cells set immune defense on right track

In the event of an infection, the immune system releases messenger substances. These molecules can either activate immune cells to defeat invading pathogens, or inhibit them to prevent an excessive immune reaction. For this, the immune system has to decide very quickly what mixture of activating and inhibiting messenger molecules leads to a successful defence.

New synthetic Petri dish harvests human embryonic stem cells

A new synthetic Petri dish coating could overcome a major challenge to the advancement of human embryonic stem cell research, say University of Michigan researchers.

Helicobacter pylori's helical shape helps it colonize the stomach

The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive - and thrive - within the stomach's acid-drenched environment, but until now they have had no proof.

Research work holds promise for biological substitute for dental implants

A technique pioneered in the Tissue Engineering and Regenerative Medicine Laboratory of Dr. Jeremy Mao, the Edward V. Zegarelli Professor of Dental Medicine at Columbia University Medical Center, can orchestrate stem cells to migrate to a three-dimensional scaffold infused with growth factor, holding the translational potential to yield an anatomically correct tooth in as soon as nine weeks once implanted.
