Latin America facing an alarming increase in cancer rates

Latin America is facing an alarming increase in cancer rates, and unless urgent action is taken to prevent cancers, improve health-care systems and facilities, access to vital medical care, and treatment of poor people, the region threatens to be overwhelmed by the burgeoning epidemic, say the authors of a major new report on cancer control in the region, published in The Lancet Oncology, and launched at the Latin American Cooperative Oncology Group (LACOG) 2013 conference in São Paulo, Brazil.

Study: Blocking certain enzymes in cell may prevent cancer cell division and growth

Blocking certain enzymes in the cell may prevent cancer cell division and growth, according to new findings from researchers at the Graduate School of Biomedical Sciences at the Icahn School of Medicine at Mount Sinai.

Mouse study shows regular exercise reduces the chance of developing liver cancer

Regular exercise has been proven to reduce the chance of developing liver cancer in a world-first mice study that carries hope for patients at risk from hepatocellular carcinoma (HCC).

Study reveals a new way for detecting colorectal cancers

A unique new study led by University of Kentucky Markey Cancer Center researchers Guo-Min Li and Libya Gu, in collaboration with Dr. Wei Yang at National Institutes of Health, reveals a novel mechanism explaining the previously unknown root cause of some forms of colorectal cancers.

Research on alpha-synuclein protein could lead to new therapies for Parkinson's disease

A protein known to be a key player in the development of Parkinson's disease is able to enter and harm cells in the same way that viruses do, according to a Loyola University Chicago Stritch School of Medicine study.

Calcipotriol drug offers a potential treatment option for fibrotic diseases

Liver fibrosis results from an excessive accumulation of tough, fibrous scar tissue and occurs in most types of chronic liver diseases. In industrialized countries, the main causes of liver injury leading to fibrosis include chronic hepatitis virus infection, excess alcohol consumption and, increasingly, nonalcoholic steatohepatitis (NASH).

NAFLD is an independent predictor of cardiovascular risk

A study presented today at the International Liver CongressTM 2013 - which evaluated the relationship between non-alcoholic fatty liver disease (NAFLD), early predictors of atherosclerosis and the 10-year Framingham risk score (FRS) - showed that NAFLD increases the risk of early atherosclerotic lesions independent of established cardiovascular (CV) risk factors.

Metabolic risk factors in overweight children linked with mild artery wall stiffness

Metabolic disorders, such as excess abdominal fat, raised blood pressure, higher levels of insulin, glucose and triglycerides and lower levels of the beneficial HDL cholesterol can be found in children as young as 6 to 8 years of age, according to a study carried out at the University of Eastern Finland.

Hormones regulate sexual desire in women

Feeling frisky? If so, chances are greater your estrogen level -- and, perhaps, fertility -- are hitting their monthly peak. If not, you're more likely experiencing a profusion of desire-deadening progesterone, and the less fertile time in your cycle.

Research on miRNAs offers new therapeutic potential to fight diseases

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes - from development to physiology to stress response.

GI nematode infections combat obesity and improve related metabolic disorders

Researchers at the University of Maryland School of Medicine, Baltimore, have shown in a mouse model that infection with nematodes (also known as roundworms) can not only combat obesity but ameliorate related metabolic disorders.

Post-stroke depression increases risk of suicide and mortality

Antidepressant medications known as SSRIs, such as fluoxetine (Prozac), sertraline (Zoloft), and escitalopram (Lexapro), are effective when given to stroke patients as a preventive measure, the physicians write in the journal Topics in Stroke Rehabilitation.

Norwegian researchers receive Fridtjof Nansen Award for pioneering work in memory research

The Fridtjof Nansen Award for excellence in science and medicine has been awarded to Norwegian University of Science and Technology Professors Edvard I. Moser and May-Britt Moser for pioneering work in memory research.

NIAID findings provide structural basis for developing RSV vaccine

An atomic-level snapshot of a respiratory syncytial virus (RSV) protein bound to a human antibody represents a leap toward developing a vaccine for a common-and sometimes very serious-childhood disease.

Violence and Gender: New refereed journal delves into gender basis of violence

Delving into controversial and unsettling subjects such as the gender basis of violence, the new refereed journal Violence and Gender, launching in fall 2013, will explore the difficult issues that are vital to threat assessment and prevention of the epidemic of violence.

Severe sports-related concussions in children prolong recovery time

Most children who suffer from sports-related concussions recover within a few days. However, in a small number of children, symptoms can last for a month or more. Although there have been numerous theories as to what might predict a longer recovery time, there is no definitive answer as to why it takes some children longer to recover.

Combinations of sEH inhibition and PPARγ activation have beneficial effects on cardiometabolic syndrome

Scientists at the Medical College of Wisconsin and the University of California at Davis, led by Dr. John Imig and Dr. Bruce Hammock have determined the synergistic actions of inhibiting soluble epoxide hydrolase (sEH) with tAUCB (trans-4-(4-[3-adamantan-1-yl-ureid]-cyclohexyloxy)-benzoic acid) and activating peroxisome proliferator-activator receptorγ (PPARγ) with the thiazolidinedione rosiglitazone on the pathological progression of cardiometabolic syndrome.

Microbial population in New York City subway system is nearly identical to that of ambient air on city streets

The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to monitor the subway's air for dispersal of potentially dangerous microbes.

Scientists report loss of dental material may be linked to reduction of tooth wear

Scientists of the Max Planck Institute for Evolutionary Anthropology in Leipzig and the Senckenberg Research Institute in Frankfurt together with dental technicians have digitally analysed modern human teeth using an engineering approach, finite element method, to evaluate the biomechanical behaviour of teeth under realistic loading.

DBS appears to reduce caloric intake and weight loss in obese animal models

Deep brain stimulation (DBS) in a precise region of the brain appears to reduce caloric intake and prompt weight loss in obese animal models, according to a new study led by researchers at the University of Pennsylvania.
