Study sheds light on Salmonella death at low temperatures

The most economical way to kill bacteria that cause common food-borne illnesses -- mostly caused by Salmonella enterica -- is heat, but, the mechanisms that kill Salmonella at lower temperatures were not fully understood until now, according to a team of researchers.

Cannabis Quality and Contamination Testing

Dr. Bob Clifford has published and presented over 125 papers in the fields of food, pharmaceutical, environmental, energy, geology, material science, photonics, and cannabis. However, his true love is in food. After graduating with his Ph.D., he left his job with the FDA for Shimadzu where he has worked for the last 26 years.

Fluorescence imaging can track vitamin C in the body

Vitamin C is best known as a nutrient. In high enough doses, however, vitamin C also shows potential against many cancers, according to recent studies. To successfully develop vitamin C (chemically named ascorbic acid) as a medication, it is crucial to probe its concentration in the body, thus ensuring safe and effective doses.

RAS dimers essential for causing cancer, study shows

Mutated RAS genes are some of the most common genetic drivers of cancer, especially in aggressive cancers like pancreatic and lung cancer, but no medicines that target RAS are available despite decades of effort.

Choosing The Correct Camera for Fluorescence Microscopy

It is important to select the proper camera for fluorescence microscopy which has high sensitivity and low noise, to avoid photo bleaching your sample. A monochrome camera is also preferred for fluorescence imaging because it does not have a color filter pattern superimposed over the image sensor. Since the microscope’s filter wheel selects which wavelength makes its way to the sensor, a monochrome camera allows equal signal detection on all pixels and increases the overall sensitivity of the camera.

Epigenetics: A New Tool for Forensic Detectives

Developing analytical methods can help the triers of fact, judges and juries, better understand the events surrounding the circumstances of a crime. In forensic analysis, we are talking about determining the identity of unknown individuals through DNA and using DNA and other chemical signatures to determine and clarify the circumstances of the crime.

Spatial deconvolution of marker expression in whole heart subjected to ischemia-reperfusion

When a coronary artery is obstructed by atheroma, blood flow is depressed or even arrested. This causes hypoxia of cardiac cells associated with the deprivation of nutrients. In clinic, the first objective is to restore blood flow. However, this is associated with a burst in oxidation of cellular proteins and lipids. This oxidation enhances cell death and participates to the so-called reperfusion injury.
