Use of PET can reduce, may eliminate more strenuous drug development trials with animals
A number of articles explore the use of positron emission tomography (PET) and small animal imaging--nonsurgical techniques that open the door to understanding and treating human diseases--in the April issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine. A major benefit of small animal imaging "is the ability to carry out many studies at various time points with the same...PET/MRI scans may help unravel mechanisms of prenatal drug damage
Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools. Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, whose findings are reported in the February issue of the Society of...Solutions that reduce death of marine life reeled in by International Smart Gear Competition
As the world prepared to observe Earth Day, World Wildlife Fund and its partners in the International Smart Gear Competition announced three new winning solutions to prevent the accidental maiming and killing of marine mammals, juvenile fish, and sea turtles that become ensnared by fishing nets and longlines--a problem known as bycatch--while also improving the efficiency of commercial fishing.</...PET/CT can identify new cancer lesions at early stage, allowing for prompt treatment
A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine. "PET/CT can help find additional...Rhesus monkeys can assess the visual perspective of others when competing for food
Researchers Jonathan Flombaum and Dr. Laurie Santos, both from Yale University, have found that rhesus monkeys consider whether a competitor can or cannot see them when trying to steal food. Working with semi-free-ranging rhesus monkeys on the island of Cayo Santiago in Puerto Rico, Flombaum and Santos set up a food competition game: Lone monkeys were approached by two human "competitors....PET at Biology Products
MCP1-S Pipette Calibration Workstation from Mettler Toledo, Inc.
Description:Unique, compact measuring instrument for calibrating single-channel and multi-channel pipettes. Thanks to its compact design and the robust carrying case, the MCP1-S is ideal for calibrating pipettes both in the laboratory and on-site at the users premises.

Researchers have found that headache stimuli also affect the appetite centre of the brain.It is always been a mystery as to why loss of appetite often accompanies pain. People with migraine, for instance, cannot face food and it is often assumed this must be because one common linked symptom is nausea. Scientists at Beth Israel Deaconess Medical Centre and Harvard Medical School no...
Hormone restrains appetite in man
According to reasearchers, a hormone is released into the blood after a meal, restrain the appetite if given by injection and might be supportive in treating obesity. The reason for feeling full after a meal, that the intestines release a hormone called PYY3-36 //which acts on the brain to produce a feeling of satiety. Researchers at Imperial College, London, now report on the first huma...Nurses competing with junior doctors in some assessments
According to a recent survey, researchers suggests that nurses and junior doctors can both carry out pre-surgery assessments of patients to the same degree of competence.There's a shortage of junior doctors in the UK// and it's been suggested that appropriately trained nurses might be able to take over some of their roles. Researchers in Ireland, UK, have compared the way in which junior...Scientists locate key hormone involved in appetite control
A key hormone involved in appetite control, called ghrelin, has been identified by researchers from the Oregon Health & Science University(OHSU). Scientists have demonstrated the effect of the hormone on the brain and have shown that the hormone activated the specialized neurons in the hypothalamus involved in weight regulation. Ghrelin is a hormone produced in the stomach with the abilit...Extra hormone found to cut appetite by a third
Studies done previously have shown that the hormone could suppress the appetites of lean people. But researchers were worried it would not work in obese people because studies of another appetite-suppressing hormone,// leptin, had proved disappointing. "We had to do a second trial to see if obese people were as sensitive" to the hormone, said researchers. The answer: "Yes, they are. The...PET at Medicine Products
