COLUMBIA, Mo. – Between 1880 and 1920, the Central Interior Highlands (CIH), consisting of Missouri, Oklahoma and Arkansas, saw the height of deforestation that also decreased the habitat for black bears and other forest species. To combat the decline of black bears and repopulate the mountainous region, more than 250 bears from Minnesota and Manitoba were relocated to Arkansas in the 1950s and 1960s.

Scientists at Queen Mary University of London (QMUL) have identified differences in the proteins present in young and old tendons, in new research that could guide the development of treatments to stop tissue breakdown from occurring.
Tendon structure in horses is similar to humans, and both face common injuries. The researchers used a horse model to undertake a thorough analysis of all the proteins and protein fragments present in healthy and injured tendons.
OAK BROOK, Ill. – Mammography-detected breast cancer is associated with a shift to earlier stage diagnosis in older women, subsequently reducing the rate of more advanced, difficult-to-treat cases, according to a new study published online in the journal Radiology. Researchers said the findings lend support to regular mammography screening in women ages 75 and older.
Queen's University scientists are helping to spearhead a new £6 million initiative to find better ways to prevent cancer.The new initiative, led by Cancer Research UK with matching investment from the BUPA Foundation, aims to support cutting-edge research to find better ways to prevent cancer.It is estimated that more than four in ten cancer cases could be prevented by lifestyle changes, such as not smoking, keeping a healthy body weight, cutting back on alcohol, eating a healthy diet, keeping active and staying safe in the sun.Professor Frank Kee, who directs the UKCRC Centre of Excellence
New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) suggests that training with alternating levels of walking intensity (interval training) could be better than walking at a constant speed to help manage blood sugar in people with type 2 diabetes. The research is by Dr Thomas Solomon, University of Copenhagen, Denmark, and colleagues.
Effective new drugs and screening would make hepatitis C a rare disease by 2036, according to a computer simulation conducted by The University of Texas MD Anderson Cancer Center and the University of Pittsburgh Graduate School of Public Health. The results of the simulation are reported in the August 5 edition of the journal Annals of Internal Medicine.
Scientists have uncovered key attributes of so-called "brown carbon" from wildfires, airborne atmospheric particles that may have influenced current climate models that failed to take the material's warming effects into account. The work was described by a collaborative team of researchers from Los Alamos National Laboratory, Carnegie Mellon University and the University of Montana in the journal Nature Geosciences this week.
Researchers from McGill University and the Génome Québec Innovation Centre have achieved a technical breakthrough that should result in speedier diagnosis of cancer and various pre-natal conditions.
Racial differences in life expectancy have declined nationally but still vary substantially across U.S. states, according to a new study by McGill University researchers. The findings, published in the journal Health Affairs, suggest that state policies could play a key role in further reducing racial differences in mortality. The researchers calculated annual state-specific life expectancies for blacks and whites from 1990 to 2009 and found that progress was uneven across states during the past two decades.
Bottom Line: Children and adolescents with an abnormal kidney ultrasonography finding or with a combination of a fever of at least 102 degrees and infection with an organism other than E.coli appear to be at high risk for renal scarring with their first urinary tract infection (UTI).

Bottom Line: Hypertension in middle age (48 to 67 years) was associated with a greater, although still a modest, decline in cognition over a 20-year period compared with individuals who had normal blood pressure.
Author: Rebecca F. Gottesman, M.D., Ph.D., of the Johns Hopkins University School of Medicine, Baltimore, and colleagues.
Background: Evidence suggests hypertension is a risk factor for cognitive change and dementia and midlife hypertension may be the stronger risk factor.
A pilot program intended to implement and test a cost-saving strategy for orthopedic procedures at hospitals in California failed to meet its goals, succumbing to recruitment challenges, regulatory uncertainty, administrative burden and concerns about financial risk, according to a new RAND Corporation study.
PASADENA, Calif., August 4, 2014 — The mantra for treatment for high blood pressure has been "the lower, the better," but that goal can potentially put patients at risk of kidney failure or death, according to a Kaiser Permanente study published today in the Journal of the American College of Cardiology.
Researchers examined the electronic health records of nearly 400,000 Kaiser Permanente patients in Southern California who were taking medications to treat high blood pressure from January 2006 through December 2010. They found that:
WASHINGTON (Aug. 4, 2014) — The polypill, a combination pill taken just once a day that includes key medications for secondary prevention of heart disease, may be an effective low-cost strategy to improve adherence to medication recommendations and reduce costs, according to researchers from Spain and New York, who reviewed research on the polypill.
FRANKFURT. Despite improved therapy, only one out of every two adult patients survive acute myeloid leukaemia (AML). The mean survival time for this disease, which predominantly occurs in the elderly, is less than a year for patients over 65 years. It is assumed that leukaemic stem cells, which cannot be completely eliminated during treatment, are the origin of relapse.
