Study on marine snails could help better understand underlying mechanisms of age-related memory loss

A new research study on marine snails uncovered the first cells in the nervous system to fail during aging. The University of Miami Rosenstiel School of Marine and Atmospheric Science researchers' findings are important to better understanding the underlying mechanisms of age-related memory loss in humans.

New chemical reaction breaks strongest bond in molecules instead of weakest

Researchers at Princeton have developed a new chemical reaction that breaks the strongest bond in a molecule instead of the weakest, completely reversing the norm for reactions in which bonds are evenly split to form reactive intermediates.

New research shows promising progress in use of anti-inflammatory cytokine for T1D treatment

New research from Uppsala University shows promising progress in the use of anti-inflammatory cytokine for treatment of type 1 diabetes. The study, published in the open access journal Scientific Reports (Nature Publishing Group), reveals that administration of interleukin-35 (a protein made by immune cells) to mice with type 1 diabetes, reverses or cures the disease by maintaining a normal blood glucose level and the immune tolerance.

Bioenergetic analysis of pancreatic beta-cells shows impaired metabolic signature in type 2 diabetes patients

Impaired activation of mitochondrial energy metabolism in the presence of glucose has been demonstrated in pancreatic beta-cells from patients with type 2 diabetes. The cause of this dysfunction has been unknown. Publishing online in Endocrinology, Buck Institute assistant research professor Akos Gerencser, PhD, shows that in patients with type 2 diabetes the balance between supply and demand of the mitochondrial membrane potential (ΔψM) is altered causing a decrease in the signaling that turns on insulin secretion.

Detailed molecular analyses reveal new treatment options for aggressive childhood leukemia

Acute lymphoblastic leukemia (ALL) leukemia is the most common type of cancer in children. It can occur in various forms, differing not only by specific changes in the genetic material of the leukemia cells but also by their response to therapies. Now, an international team of scientists from Berlin, Düsseldorf, Hannover, Heidelberg, Kiel, and Zurich have succeeded in decoding the molecular characteristics of an as yet incurable subtype of leukemia, paving the way for new therapeutic approaches.

Articles explore mechanisms of repetitive thinking that contributes to mental health, illness

The ability to engage in mental time travel -- to delve back into past events or imagine future outcomes -- is a unique and central part of the human experience. And yet this very ability can have detrimental consequences for both physical and mental well-being when it becomes repetitive and uncontrolled.

Cancer Research UK scientists identify five distinct types of prostate cancer

Cancer Research UK scientists have for the first time identified that there are five distinct types of prostate cancer and found a way to distinguish between them, according to a landmark study published today in EBioMedicine.

Smaller doses of resveratrol more effective at preventing bowel cancer

Resveratrol, a chemical found in red grapes, is more effective in smaller doses at preventing bowel cancer in mice than high doses, according to new research published today (Wednesday) in the journal Science Translational Medicine.

New study reports creation of genetic porcine model of cancer

With many types of cancers, early detection offers the best hope for survival. However, research into new early-detection screenings, as well as possible interventional radiology and surgical treatments, has been hindered by the lack of a large animal model that would accurately reflect the types of cancers seen in human cells.

Scientists study role of protein oxidation in the ageing process

Research published in the journal Cell Reports challenges the most popular theory about why our bodies deteriorate in old age. Scientists know that as we grow older our cells accumulate particles, called free radicals.

Blocking the expression of certain gene reduces excessive fat in patients

By blocking the expression of a certain gene in patients, University of Montreal researchers have contributed to the demonstration of great decreases in the concentration of triglycerides in their blood, even in various severe forms of hypertriglyceridemia and regardless of the base values or the treatment the patient usually receives.

UIC, Northwestern University researchers create first artificial ribosome

Researchers at the University of Illinois at Chicago and Northwestern University have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.

Low blood level of 4 proteins can help diabetics protect against immune attack

Patients with type 1 diabetes have significantly lower blood levels of four proteins that help protect their tissue from attack by their immune system, scientists report.

Protecting gastrointestinal system during radiation or chemotherapy allows patients to tolerate cancer treatments

The stem cells in our gut divide so fast that they create a completely new population of epithelial cells every week. But this quick division is also why radiation and chemotherapy wreak havoc on the gastrointestinal systems of cancer patients - such therapies target rapidly dividing cells.

Discovery could put individuals with relapsing UTIs on fast track for new therapeutic regimen

It's one thing to grow bacteria in a test tube, perform a screen in the lab, and find a mutation in the pathogen's genes. It's a whole other thing, and much rarer, to find the exact same mutation in nature--in this case, in E. coli in urine samples from some 500 patients suffering from relapsing urinary tract infections.

Researchers demonstrate direct connection between NOX proteins and liver fibrosis

Researchers at the University of California, San Diego School of Medicine have demonstrated a direct connection between two signaling proteins and liver fibrosis, a scarring process underlying chronic liver disease, the 12th leading cause of death in the United States.

Understanding the workings of error correction mechanism in cell division

Cell biologists led by Thomas Maresca at the University of Massachusetts Amherst, with collaborators elsewhere, report an advance in understanding the workings of an error correction mechanism that helps cells detect and correct mistakes in cell division early enough to prevent chromosome mis-segregation and aneuploidy, that is, having too many or too few chromosomes.

Natural protein fragment produced in the brain can inhibit enzyme implicated in Alzheimer's disease

For the first time, UCLA researchers have shown that a natural protein fragment produced in the brain can act as an inhibitor of a key enzyme implicated in the onset of Alzheimer's disease, a finding that could lead to the development of new drugs to treat the disease.
