Fluorescence Microscopy News and Research

RSS

Fluorescence microscopy is an imaging technique used to examine cells and their internal components. Specific cellular components can be labeled with fluorophores.

Biomedical spectroscopy suggests excess copper may be neurotoxic in Alzheimer's patients

Metals such as iron, copper, and zinc are important for many biological processes. In recent years, studies have shown that these nutritionally-essential metals are elevated in human Alzheimer's disease (AD) brains and some animal models of AD. Scientists are now exploring whether these metals are causing the neurodegeneration seen in AD or are indicative of other ongoing pathologic processes.

STED-RICS microscopy method records rapid movements of molecules in live samples

The newly developed STED-RICS microscopy method records rapid movements of molecules in live samples. By combining raster image correlation spectroscopy (RICS) with STED fluorescence microscopy, researchers of Karlsruhe Institute of Technology (KIT) opened up new applications in medical research, e.g. analyzing the dynamics of cell membranes at high protein concentrations.

New chemical probe confirms that hydrogen sulfide is generated by body's growing cells.

A new study confirms directly what scientists previously knew only indirectly: The poisonous "rotten egg" gas hydrogen sulfide is generated by our body's growing cells.

UNM scientists identify chemical compound that appears to control cell metastases

It's the spread of the original cancer tumor that kills most people. That's why cancer researchers vigorously search for drugs that can prevent metastases, the spread of cancer. The research team co-led by Angela Wandinger-Ness, PhD, and Larry Sklar, PhD, at the University of New Mexico Cancer Center has found a chemical compound that appears to control cell migration and adhesion, two important characteristics of metastatic cancer cells.

Bioelectric signals can identify cells that are likely to develop into tumors

Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes.

Salk scientists' discovery explains how a class of chemotherapy drugs works

The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews restitch anything that resembles a broken chromosome. If repair is impossible, the crew foreman calls in executioners to annihilate a cell. As unsavory as this last bunch sounds, failure to summon them is one aspect of what makes a cancer cell a cancer cell.

Researchers observe how cholera decimates competing bacteria and human cells

Bacteria live in a state of perpetual warfare, with different species battling for dominion over their competitors and when pathogen, over their infected host. New research suggests that the human pathogen Vibrio cholerae, which causes the disease cholera, kills off its microbial rivals by jabbing them with a spring-loaded poison dagger.

Fluorescence microscopy reveals 3-D picture of myoV's transport capacity

A new study in the Journal of General Physiology uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track.

New assay simultaneously visualize gene number, protein expression in individual cells

Researchers have discovered a method for simultaneously visualizing gene number and protein expression in individual cells. The fluorescence microscopy technique could permit a detailed analysis of the relationship between gene status and expression of the corresponding protein in cells and tissues, and bring a clearer understanding of cancer and other complex diseases, according to researchers who led the study

Efficient, economical molecule could speed evaluation of some anti-cancer treatments

Researchers from Boston College have developed a new class of small molecule receptors capable of detecting a lipid molecule that reveals the telltale signs of cellular death, particularly cancer cells targeted by anti-cancer drugs, the team reports in the current electronic edition of the Journal of the American Chemical Society.

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.

Super microscopes help scientists identify exact molecular 'switch' that spurs T-cells into action

Using the only microscope of its kind in Australia, medical scientists have been able for the first time to see the inner workings of T-cells, the front-line troops that alert our immune system to go on the defensive against germs and other invaders in our bloodstream.

Researchers identify new mechanism underlying MS

Multiple sclerosis is a disabling autoimmune disease in which nerve fibers are attacked by the patient's own immune system. Researchers at Ludwig-Maximilians-Universitaet in Munich have identified a new mechanism that contributes to nerve fiber damage - and shown that this damage can be reversed.
