Protecting powerhouse of cells could provide better way to treat acute kidney injury

Thu, 12/06/2018 - 13:43
For the first time, scientists have described the body's natural mechanism for temporarily protecting the powerhouses of kidney cells when injury or disease means they aren't getting enough blood or oxygen.

Mapping brain microglia

Thu, 12/06/2018 - 13:37
Microglia are known to be important to brain function. The immune cells have been found to protect the brain from injury and infection and are critical during brain development, helping circuits wire properly. They also seem to play a role in disease -- showing up, for example, around brain plaques in people with Alzheimer's.

Heroin-assisted treatment can offer benefits, reduce harms

Thu, 12/06/2018 - 13:34
Providing supervised access to medical-grade heroin to people whose use continues after trying multiple traditional treatments has been successful in other countries, and should be piloted and studied in the United States, according to a new RAND Corporation study.

Study reveals how the absence of Dna2 enzyme affects chromosome instability

Thu, 12/06/2018 - 13:31
Cells have in place a number of mechanisms to protect the integrity of the genome, including processes that repair mistakes that may occur during DNA replication.

Postmenopausal women who experience tooth loss more likely to develop high blood pressure

Thu, 12/06/2018 - 13:26
Postmenopausal women who have experienced loss of all teeth are at higher risk of developing high blood pressure, according to a recent University at Buffalo study published in the American Journal of Hypertension. Multiple studies have suggested an association between periodontal disease and tooth loss with hypertension, but the relationship with time remains unclear with these associations.

New method could lead to better understanding of complex interactions between human gut microbes

Thu, 12/06/2018 - 13:23
The gut microbiome -- the world of microbes that inhabit the human intestinal tract -- has captured the interest of scientists and clinicians for its critical role in health.

Elevated air pollution associated with increased risk for miscarriage

Thu, 12/06/2018 - 13:20
Air quality has been associated with numerous adverse health outcomes from asthma to pre-term birth. Researchers at University of Utah Health found women living along the Wasatch Front -- the most populous region in the state of Utah -- had a higher risk (16 percent) of miscarriage following short-term exposure to elevated air pollution. The results are available online on December 5 in the journal Fertility and Sterility.

Liraglutide drug associated with lower risk of cardiovascular events

Thu, 12/06/2018 - 13:20
Real world data from a large Nordic study shows that use of liraglutide, a drug for type 2 diabetes, is associated with a lower risk of myocardial infarction, stroke or cardiovascular death.

Study expands knowledge about sexuality and gender gaps in political attitudes

In a web-based study reported in the Canadian Journal of Cardiology, more than three quarters of French-speaking adults in Quebec, Canada, fall short of meeting current dietary guidelines regarding consumption of fruits and vegetables, whole grains, sodium, and saturated fats.

Researchers develop biosensors to detect and measure metastatic potential of cancer cells

Thu, 12/06/2018 - 12:19
The spread of invasive cancer cells from a tumor's original site to distant parts of the body is known as metastasis. It is the leading cause of death in people with cancer. In a paper published online in iScience, University of California San Diego School of Medicine researchers reported engineering sensors that can detect and measure the metastatic potential of single cancer cells.

Thu, 12/06/2018 - 12:08
Stroke patients prescribed a common antidepressant show no improvement compared with those given a dummy drug, a study has found.

Study shows correlation between childhood infections and increased risk of mental disorders

Thu, 12/06/2018 - 11:54
A new study from iPSYCH shows that the infections children contract during their childhood increase the risk of mental disorders during childhood and adolescence. This knowledge expands our understanding of the role of the immune system in the development of mental disorders.

Thu, 12/06/2018 - 11:37
Alzheimer's disease symptoms, such as memory loss or cognitive decline, can present in different ways among people with diverse ethnic backgrounds. Researchers know that a complex mix of social, behavioral, and genetic variables can impact the onset and progression of this disease.

EHR-related stress associated with physician burnout

Thu, 12/06/2018 - 11:30
While electronic health records improve communication and access to patient data, researchers found that stress from using EHRs is associated with burnout, particularly for primary care doctors such as pediatricians, family medicine physicians and general internists.

Financial difficulties add to patients' cancer struggle

Thu, 12/06/2018 - 11:00
One in five cancer patients could be experiencing financial difficulties because of their care needs, according to new research published in the Journal of Cancer Survivorship.

Spinal cord injury disrupts the body's internal clock, study shows

Thu, 12/06/2018 - 10:51
Although paralysis is the most noticeable result of a spinal cord injury, a new study by researchers at The University of Texas at Austin suggests such injuries could throw off the internal clock of the entire body's daily activities, from hormones to sleep-wake schedules.

New therapeutic strategy is emerging for type 2 diabetes

Thu, 12/06/2018 - 10:46
Diabetes is a disease in which blood sugar levels are high over a prolonged period (hyperglycemia). In the case of type 2 diabetes, this phenomenon which is caused by a disruption of the glucose metabolism develops progressively and insidiously.
