The presence of chronic inflammation in benign prostate tissue was associated with high-grade, or aggressive, prostate cancer, and this association was found even in those with low prostate-specific antigen (PSA) levels, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

An analysis of prostate tissue biopsies collected from some participants of the placebo arm of the Prostate Cancer Prevention Trial (PCPT) found that those whose benign prostate tissue had chronic inflammation had 1.78 times higher odds of having prostate cancer, and 2.24 times higher odds of having an aggressive disease (characterized by Gleason sum of seven to 10), compared with those whose benign prostate tissue had no inflammation.
As a plant, rice is particularly prone to absorbing certain toxic metals from the soil.
For the past few years, Mary Lou Guerinot has been keeping watch over experimental fields in southeast Texas, monitoring rice plants as they suck metals and other troublesome elements from the soil.
If the fields are flooded in the traditional paddy method, she has found, the rice handily takes up arsenic. But if the water is reduced in an effort to limit arsenic, the plant instead absorbs cadmium — also a dangerous element.
“It’s almost either-or, day-and-night as to whether we see arsenic or cadmium in the rice,” said Dr. Guerinot, a molecular geneticist and professor of biology at Dartmouth College.

World Health Organization’s (WHO) first global report on antibiotic resistance reveals serious worldwide threat to public health
April 20, 2014 | Geneva
A new report by WHO–its first to look at antimicrobial resistance, including antibiotic resistance, globally–reveals that this serious threat is no longer a prediction for the future, it is happening right now in every region of the world and has the potential to affect anyone, of any age, in any country. Antibiotic resistance–when bacteria change so antibiotics no longer work in people who need them to treat infections–is now a major threat to public health.
“Without urgent, coordinated action by many stakeholders, the world is headed for a post-antibiotic era, in which common infections and minor injuries which have been treatable for decades can once again kill,” says Dr Keiji Fukuda, WHO’s Assistant Director-General for Health Security.
