Novel 3D human skin tissue model could help detect presence of known skin sensitizers in medical device extracts

New research shows that exposing a 3D human skin tissue model to extracts of medical device materials can detect the presence of sensitizers known to cause an allergic response on contact in some individuals. Conventional skin sensitization testing of medical devices relies on animal testing, whereas human skin models could replace animal methods, according to an article in the new journal Applied In Vitro Toxicology, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

Study sheds light on certain antagonist drugs that block physiological responses

Members of the Consolidated Research Group of Molecular Neurobiology of the Department of Biochemistry and Molecular Biology of the University of Barcelona (UB), affiliated with the Centre for Networked Biomedical Research on Neurodegenerative Diseases (CIBERNED), have published a study in the journal Proceedings of the National Academy of Sciences (PNAS) about the formation of G protein-coupled receptors (GPCRs) which allows understanding the unexpected behaviour of some antagonists that block physiological responses.

Plants send out stress signals normally associated with animals

University of Adelaide research has shown for the first time that, despite not having a nervous system, plants use signals normally associated with animals when they encounter stress.

Balancing cellular aging and cancer risk through biotechnology

In a way, trying to repair age-related heart damage and trying to fight cancer are opposite problems. Your heart cells' ability to regenerate themselves and proliferate into new, young cells degrades as you get older.

Research: Algae’s natural sunscreen molecules absorb UVA and UVB radiation with high efficiency

For consumers searching for just the right sunblock this summer, the options can be overwhelming. But scientists are now turning to the natural sunscreen of algae -- which is also found in fish slime -- to make a novel kind of shield against the sun's rays that could protect not only people, but also textiles and outdoor materials.

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.
