NKTreg white blood cells migrate into liver, suppress immune responses: Research

After a transplant - and to assure that the new organ is not rejected - patients are put on life-long therapy to suppress their immune system, which, nevertheless, needs to be left intact enough to be able to defend the body against all kinds of disease. A tricky balance as the many rejected organs attest. But a discovery by Maria Monteiro and Luis Graça, two Portuguese scientists, could change all this, at least for the liver.

GoTaq 2-Step RT-qPCR System allows researchers to detect target genes

The new Promega GoTaq 2-Step RT-qPCR System allows researchers to detect target genes expressed at low levels even with hard-to-amplify samples. Enhanced sensitivity of the two-step system extends the broad dynamic range of RNA quantitation and provides a robust, gene expression analysis tool.

Healthy eggs require tremendous amount of zinc to reach maturity for fertilization: Research

Scientists as well as fertility doctors have long tried to figure out what makes a good egg that will produce a healthy embryo. It's a particularly critical question for fertility doctors deciding which eggs isolated from a woman will produce the best embryos and, ultimately, babies.New research reveals healthy eggs need a tremendous amount of zinc to reach maturity and be ready for fertilization,a finding that may ultimately help physicians assess the best eggs for fertility treatment, according to a study from Northwestern University.

UCSF researchers discover new technology purifying special types of stem cells

UCSF researchers are reporting the first success in very rapidly purifying one type of embryonic stem cell from a mix of many different types of embryonic stem cells in the culture dish. The technique, which avoids the need to genetically alter the cells to distinguish them, is a key advance, the researchers say, for obtaining the appropriate cells for repairing specific damaged tissues.

Scientists invent Global Focus microscope for tuberculosis diagnosis

A compact microscope invented at Rice University is proving its potential to impact global health. In a paper published online today in the journal PLoS ONE, Rice alumnus Andrew Miller and co-authors show that his portable, battery-operated fluorescence microscope, which costs $240, stacks up nicely against devices that retail for as much as $40,000 in diagnosing signs of tuberculosis.

Scientists develop laser probe for early detection of oral cancer

UC Davis researchers have developed a laser probe for the early detection of oral cancer. A trial with human subjects shows that the device could also be used during surgery to locate the edges of a tumor.

New study of breast cancer survivors may help physicians ease side effect of treatments

A new study of breast cancer survivors may help physicians ease a common side effect of cancer treatments. The collaborative research by Eva Sevick, Ph.D., Director of the Center for Molecular Imaging at the University of Texas Health Science Center in Houston, and Caroline Fife, M.D., Director of the Memorial Herman Wound Care Clinic at UTHSC, could bring relief to millions.

New FEI software package increases electron microscope throughput, ease-of-use

FEI Company ,a leading scientific instrumentation company providing electron microscopy systems for nanoscale applications across many industries, released today a set of software applications that increase the throughput and ease-of-use of its electron microscopes for biological research. The four software packages make electron microscopes more useful for life science researchers involved in structural, cellular and tissue biology as they build the full solution from sample to biological answer.

Exercise, restricted-calorie diets help to stave off mental, physical degeneration of aging: Research

Harvard University researchers have uncovered a mechanism through which caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating connections between nerves and the muscles that they control.

Researchers develop techniques to identify evolution of drug resistance strains of malaria

Researchers at Case Western Reserve University developed techniques to quickly identify evolution of drug resistance in strains of malaria. Their goal is to enable the medical community to react quickly to inevitable resistance and thereby save lives while increasing the lifespan of drugs used against the disease.Currently, disease monitoring requires months of clinical trials. The new methods can provide more information in just days, and far cheaper.

Researchers develop new fluorescent biosensor for drug development

Researchers at Carnegie Mellon University have developed a new fluorescent biosensor that could aid in the development of an important class of drugs that target a crucial class of proteins called G protein-coupled receptors (GPCRs).

Tel Aviv University discovers molecular power behind memory

Neuroscientists have long wondered how individual connections between brain cells remain diverse and "fit" enough for storing new memories. Reported in the prestigious science journal Neuron, a new study led by Dr. Inna Slutsky of the Sackler School of Medicine at Tel Aviv University describes what makes some memories stick.

Scientists develop nanoprobe to detect blood vessel growth in tumors

Formation of new blood vessels, also known as angiogenesis, is crucial for sustained tumor growth and cancer metastasis. Recently, clinically available therapies to suppress the growth of these vessels have been available to improve patient survival in some cancer types. Accurate detection and quantification of blood vessel growth using nonsurgical methods would greatly complement current therapies and allow physicians to quickly assess treatment regimens and adjust them as necessary. In the work published in the August issue of Experimental Biology and Medicine, Kessinger and coworkers have incorporated nanotechnology, material science, and the clinical imaging modality MRI, to create a nanosized probe capable of noninvasively visualizing and quantifying the blood vessel growth in tumors in a preclinical model.

New biophotonic imaging method monitors transformations of cellular macromolecules during apoptosis in real-time

Apoptosis, programmed cell death, is essential to normal development, healthy immune system function, and cancer prevention. The process dramatically transforms cellular structures but the limitations of conventional microscopy methods have kept much about this structural reorganization a mystery.

Circulating aberrant cells increase as non-small cell lung cancer progresses

A novel approach detects genetically abnormal cells in the blood of non-small cell lung cancer patients that match abnormalities found in tumor cells and increase in number with the severity of the disease, a research team led by scientists at The University of Texas MD Anderson Cancer Center report in the journal Clinical Cancer Research.
