Research study finds that higher intake of fruits and vegetables may reduce the risk of bladder cancer in women

2013-08-23

(Press-News.org) HONOLULU, HI – University of Hawaii Cancer Center Researcher Song-Yi Park, PhD, along with her colleagues, recently discovered that a greater consumption of fruits and vegetables may lower the risk of invasive bladder cancer in women.

The investigation was conducted as part of the Multiethnic Cohort (MEC) Study, established in 1993 to assess the relationships among dietary, lifestyle, genetic factors, and cancer risk. Park and her fellow researcher's analyzed data collected from 185,885 older adults over a period of 12.5 years, of which 581 invasive bladder cancer cases were diagnosed (152 women and 429 men).

After adjusting for variables related to cancer risk (age, etc.) the researchers found that women who consumed the most fruits and vegetables had the lowest bladder cancer risk. For instance, women consuming the most yellow-orange vegetables were 52% less likely to have bladder cancer than women consuming the least yellow-orange vegetables. The data also suggested that women with the highest intake of vitamins A, C, and E had the lowest risk of bladder cancer. No associations between fruit and vegetable intake and invasive bladder cancer were found in men.

"Our study supports the fruit and vegetable recommendation for cancer prevention, said Park. "However, further investigation is needed to understand and explain why the reduced cancer risk with higher consumption of fruits and vegetables was confined to only women."

### Their findings that greater consumption of fruits and vegetables may lower the risk of invasive bladder cancer among women are published in the August 2013 issue of The Journal of Nutrition.

Sea ice decline spurs the greening of the Arctic

2013-08-23

Fairbanks, Alaska— Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists. Uma Bhatt, an associate professor with UAF's Geophysical Institute, and Skip Walker, a professor at UAF's Institute of Arctic Biology, contributed to a recent review of research on the response of plants, marine life and animals to declining sea ice in the Arctic. "Our thought was to see if sea ice decline contributed to greening of the tundra along the coastal areas," Bhatt said. "It's a relatively ...

Underwater intelligence

VIDEO: This shows confidence regions (grey contours) for the location of a fish at Palmyra Atoll, along with home range (green line) estimated by the state-space model. Click here for more information. There's no "Google Maps" for finding fish. The radio signals that are the backbone of traditional GPS cannot pass through seawater. But sound travels remarkably well, so scientists often use acoustic telemetry to estimate an individual fish's location. That means attaching ...

Architecture of chromosomes: A key for success or failure

2013-08-23

In a pioneer study published in the latest issue of the scientific journal Nature Communications*, a research team at the Instituto Gulbenkian de Ciência (IGC; Portugal), led by Miguel Godinho Ferreira in collaboration with Isabel Gordo, show for the first time that chromosomes rearrangements (such as inversions or translocations) can provide advantages to the cells that harbor them depending on the environment they are exposed. This study contributes to better understand different biological problems such as: how cancer cells that have chromosomal rearrangements can outgrow ...

Out of Africa? New bamboo genera, mountain gorillas, and the origins of China's bamboos

2013-08-23

African mountain bamboos are something of a mystery, as nearly all bamboos are found in Asia or South America. Hidden away up mountains in the tropics where they provide food for gorillas, just as China's bamboos provide food for the Giant Panda, there are apparently only 2 species, and they had not been examined in very great detail, except by the gorillas, Fig. 1. It had been thought that they were very closely related to the hundreds of similar bamboos in Asia, but their respective ranges are separated by thousands of miles. As flowering in bamboos is such a rare ...

New technique to help brain cancer patients

2013-08-23

A new scanning technique developed by Danish and US researchers reveals how susceptible patients with aggressive brain cancer are to the drugs they receive. The research behind the ground-breaking technique has just been published in Nature Medicine. Each year sees 260 new cases of the most aggressive type of brain cancer in Denmark. Some patients survive only a few months, while others survive for 18 months. Only very few, 3.5%, are alive five years after their diagnosis. A new scanning technique can now reveal how the brain tumour responds to the drug administered: "We ...

Gut taste mechanisms are abnormal in diabetes sufferers

2013-08-23

Researchers at the University of Adelaide have discovered that the way the gut "tastes" sweet food may be defective in sufferers of type 2 diabetes, leading to problems with glucose uptake. This is the first time that abnormal control of so-called "sweet taste receptors" in the human intestine has been described by researchers. The work could have implications for a range of health and nutrition problems experienced by diabetes patients. Dr Richard Young, Senior Postdoctoral Researcher in the University of Adelaide's Nerve-Gut Research Laboratory, says taste buds aren't ...

LSUHSC study reports racial/ethnic differences in young people with cancer

Gene combinations and interactions affect risk of Crohn's disease

2013-08-23

Philadelphia, Pa. (August 22, 2013) – A statistical model accounting for dozens of different genes in combination—and the interactions between them—is an important step forward in understanding the genetic factors affecting the risk of Crohn's disease (CD), reports a study in Inflammatory Bowel Diseases, official journal of the Crohn's & Colitis Foundation of America (CCFA). The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. It's not just how many risk genes are present but how those genes interact with each other that determines ...

Unprecedented control of genome editing in flies promises insight into human development, disease

2013-08-23

MADISON — In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function. A paper from the University of Wisconsin–Madison in the August issue of the journal GENETICS takes genome editing to a new level in fruit flies, demonstrating a remarkable level of fine control and, importantly, the transmission of those engineered genetic changes across generations. Both features are key for driving the utility and spread of an approach that promises to give ...

Who uses social networking sites to monitor their romantic partners?

2013-08-23

New Rochelle, NY -- With the widespread popularity of social networking sites such as Facebook, it is increasingly common for people to use interpersonal electronic surveillance to monitor the activities of current and former romantic partners. They can gather information on partners anonymously, view past and current photos and audio and video clips, and look for clues to explain any "suspicious" behaviors. Why some individuals engage in this type of behavior more than others is the subject of an article in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed ...
