Flavanols help smokers repair blood vessel function

Phytochemicals known as flavanols, which are found in chocolate, fruits and vegetables, can boost the levels of nitric oxide in the blood of smokers and reverse some of their smoking-related impairment in blood vessel function, according to a new study in the Oct. 4, 2005, issue of the Journal of the American College of Cardiology.

Potatoes found to help reduce blood pressure and other diseases

UK scientists have identified bioactive plant chemicals in the most practical of staple foods, the potato. These natural chemicals have been associated with reduced blood pressure and they selectively affect a chemotherapeutic target for trypanosomes and similar diseases such as sleeping sickness.

New research raises the possibility that the risk of developing arsenic-related disease is not the same for everybody

Children with a particular variation in the CYT19 gene metabolize arsenic differently than adults with the same genetic variant, according to a new research report. The findings have important implications for the safety of drinking water worldwide and the use of arsenic as a cancer drug.

Pregnant women's exposure to phthalates has adverse effects on genital development in their male children

For the first time, researchers have identified an association between pregnant women’s exposure to a nearly ubiquitous class of chemicals known as phthalates and adverse effects on genital development in their male children.

Researchers determine mechanism of action of chemotherapy drug motexafin gadolinium

The chemotherapy drug motexafin gadolinium (brand name: Xcytrin, manufactured by Pharmacyclics, Inc.) works to thwart cancer cells by disrupting key enzymes involved in cellular metabolism, according to a team of researchers led by Joseph Hacia, Ph.D., assistant professor of biochemistry and molecular biology at the Keck School of Medicine of the University of Southern California.

Low levels of oral cannabis induces psychosis

Recreational cannabis use has previously been associated with psychotic reactions even in clinical situations where cannabis is administered orally at low doses, now Swiss researcher Dr. Bernard Favrat and colleagues at Institut Universitaire de Medicine Legale in Lausanne have confirmed this in the first such report, in closely monitored subjects participating in a clinical trial.

Cannabis-based medicines given in a highly-controlled clinical environment unexpectedly lead to strong psychotic effects

Volunteers taking cannabis-based therapeutic drugs as part of a controlled trial, which had been approved by an ethics board as safe for the subjects, experienced psychotic effects just as strong as if they had smoked cannabis. These findings, highly unexpected in such a controlled environment, are published today in the peer-reviewed, Open Access journal BMC Psychiatry.

Green alga closes wounds by means of enzymatic activation of a cross-linking protein

A small wound is painful, but is normally not a problem. Like all multicellular organisms, our bodies form new tissue around the damaged cells. Single-celled organisms cannot do this. In order to survive an injury, they have to quickly repair the cell itself. Large single-celled organisms, such as the green alga Caulerpa taxifolia, which can be several meters long, are especially at risk for injuries.

New way to assess the potentially damaging effects of prenatal drug exposure

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.

Low level exposure to Benzene causes lower blood cell counts

A new study found that white blood cell counts were lowered in workers exposed to less than 1 ppm of the chemical benzene (part benzene per million parts air).

Magnetic resonance spectroscopy may prove to be the definitive diagnostic test for bipolar disorder

Magnetic resonance (MR) spectroscopy may prove to be the definitive diagnostic test for bipolar disorder, a serious brain illness characterized by an alternating pattern of extreme emotional highs and lows, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

Study highlights importance of pesticide worker dermal exposure

Agricultural pesticide workers are not only exposed to pesticides from inhalation, but also through their skin. The dermal route of exposure to chlorpyrifos, a common agricultural pesticide, is known to contribute substantially to workers’ total exposure

Celebrex may one day be used to prevent and even treat breast tumors

The anti-inflammatory drug Celebrex, or celecoxib, reduces tumor mass by encouraging cell death and discouraging both cell proliferation and the sprouting of new blood vessels that feed growing tumors, according to a study reported in the November issue of Molecular Cancer Research.

Flame retardants may cause brain damage

Reduced adaptability, hyperactivity, and disturbances in memory and learning functions. These are deficiencies mice and rats evince when exposed to bromide flame retardants, such as those found in computers, textiles, and other materials in our surroundings, during the period when the brain develops most rapidly.

Study will evaluate arsenic exposure from the environment and its potential carcinogenic effects

The National Cancer Institute has awarded the Arizona Cancer Center at the University of Arizona Health Sciences Center a three-year grant to evaluate associations between elevated arsenic exposure and cancer incidence in Arizona and Mexico.

First sliver-sized sensor to monitor glucose level for diabetics and other bodily fluid levels

It's a good thing that the now eight-year-old son of Miklos Gratzl, a Case Western Reserve University biomedical engineer, got a splinter in his finger one day – at least for the sake of science. With apologies to his son – instead of an "Ouch!" moment, for Gratzl it was more of an "A-ha!" moment.
