New approach allows researchers to trap and watch highly motile cells

Optical imaging of highly motile cells or cells in suspension, such as bacterial systems, yeast cells, and immune cells, is a challenging task, in many cases it is just not possible. The human immunodeficiency virus (HIV), for example, can spread very efficiently from an infected T cell to an uninfected T cell through direct cell-cell contact.

Researchers solve secret of mysterious reverse-wired eyeball

From a practical standpoint, the wiring of the human eye - a product of our evolutionary baggage - doesn't make a lot of sense. In vertebrates, photoreceptors are located behind the neurons in the back of the eye - resulting in light scattering by the nervous fibers and blurring of our vision.

Leica Microsystems offers preview of light sheet module for confocal microscope at ASCB annual meeting

At the annual meeting of the American Society for Cell Biology (ASCB) in Philadelphia, PA, USA, from December 6 to 10, 2014, Leica Microsystems offers visitors a preview of its latest development: a light sheet module as an optional add-on to the Leica TCS SP8 confocal microscope for the observation of developing organisms in real time and 3D. The synergy of light sheet and confocal microscopy opens novel fields of application.

New techniques offer insight into cell-by-cell makeup of organisms

In general, our knowledge of biology-and much of science in general-is limited by our ability to actually see things. Researchers who study developmental problems and disease, in particular, are often limited by their inability to look inside an organism to figure out exactly what went wrong and when.

Leica Application Suite Advanced Fluorescence 4.0 now launched for advanced life science research

Leica Microsystems has launched the Leica Application Suite Advanced Fluorescence (LAS AF), the software platform for advanced life science research in widefield and confocal microscopy, in its 4.0 version.

Corneal nerve fiber assessment has potential to monitor peripheral neuropathy induced by HIV

Corneal nerve fiber assessment has great potential as a tool to diagnose and monitor peripheral neuropathy induced by HIV, say scientists at the Johns Hopkins University School of Medicine.

NIBIB-funded researchers develop microscopic technique to improve Mohs surgery

A common surgery for non-melanoma skin cancer, known as Mohs surgery typically achieves excellent results but can be a long process, as the surgeon successively removes the area of concern until the surrounding tissue is free of cancer.

Parkin and PINK1 function in vesicular trafficking pathway regulates mitochon-drial quality control

Scientists from the Montreal Neurological Institute and Hospital in Canada have discovered that two genes linked to hereditary Parkinson's disease are involved in the early-stage quality control of mitochondria.

MIT researchers develop microfluidic device that mimics flow of cancer cells through blood vessels

Cancer cells metastasize in several stages -- first by invading surrounding tissue, then by infiltrating and spreading via the circulatory system. Some circulating cells work their way out of the vascular network, eventually forming a secondary tumor.

New optical imaging tool enables scientists to observe tumors and uncover inner workings

Scientists seeking new ways to fight cancer often try to understand the subtle, often invisible, changes to DNA, proteins, cells, and tissue that alter the body's normal biology and cause disease.

Research suggests clingy blood platelets may offer hope for people with rheumatoid arthritis

No one likes clingy people, but "clingy" blood platelets may offer hope for millions of people with rheumatoid arthritis. According to new research findings published in The Journal of Leukocyte Biology, a sub population of immune cells (lymphocytes) known to play a significant role in rheumatoid arthritis has platelets attached to their surface.

Study shows ABL kinases have enhanced expression and activity in CML

Chronic Myelogenous Leukemia (CML) is a cancer of the white blood cells that is most commonly found in adults and in the elderly. Its incidence has been estimated to be 1 to 2 in 100,000 people. CML was the first cancer to be associated with a genetic abnormality, known as the Philadelphia Chromosome, which 95% of all CML patients carry in their cells.

New research reveals how endothelium maintains highly efficient barrier function

The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system.

WUSTL's Wang receives NSF grant to study oxygen consumption rates of individual cells

When scientists study cells, they need to know how much oxygen each cell consumes to determine its metabolism. However, existing technology limits this study to groups of cells, not individual cells. Lihong Wang, PhD, plans to change that.

Two renowned SCCP scientists earn national recognition from Society of Toxicology

Two renowned scientists at the South Carolina College of Pharmacy (SCCP) have garnered national recognition from the Society of Toxicology (SoT), which named them recipients of two of its individual annual awards. It is the first time these awards have gone to individuals from the same College.

New research examines role of PKC in airway smooth muscle contraction

New research examines the role of PKC in airway smooth muscle contraction and raises the possibility that this enzyme could be a therapeutic target for treating asthma, COPD, and other lung diseases.

Confocal light sheet microscopy yields high-resolution views of brain’s neural pathways

Shortly after the Hubble Space Telescope went into orbit in 1990 it was discovered that the craft had blurred vision. Fortunately, Space Shuttle astronauts were able to remedy the problem a few years later with supplemental optics. Now, a team of Italian researchers has performed a similar sight-correcting feat for a microscope imaging technique designed to explore a universe seemingly as vast as Hubble's but at the opposite end of the size spectrum—the neural pathways of the brain.

Study identifies how RNA viruses hijack a host cell to multiply

By discovering how certain viruses use their host cells to replicate, UC Irvine microbiologists have identified a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold.
