Hybrid cells cause chaos around cancers Like all cells, those in tumors need access to the body's fine network of blood vessels to bring them oxygen and carry away waste. Tumors have learned to game the process called angiogenesis in which new vessels sprout from existing ones, like branches from a tree. Now, researchers have built a simulation to understand how cancerous tumors manipulate blood-vessel growth
Multiple myeloma hides in bones like a wolf in sheep's clothing Multiple myeloma uses a trick akin to a wolf in sheep’s clothing to grow in and spread to new bone sites. By overexpressing Runx2, a gene that normally is a master regulator of bone formation, the cells of this largely incurable cancer produce proteins that mimic the normal bone-resident cells.
New technique for precise light-activated chemotherapy drugs A new technique that uses light to activate chemotherapy drugs in specific cells shows promise as a way to improve the effectiveness of cancer therapies while preventing severe side effects, according to a study. The approach could be used to treat a range of tumors with unprecedented precision by making existing cancer drugs sensitive to light
Super graphene can help treat cancer Silver is often used as a coating on medical equipment used for chemotherapy. The problem is that this silver coating can break down drugs. Now, researchers have found a graphene coating that will help boost chemotherapy's effects.
Cell structure discovery advances understanding of cancer development A cell structure has been discovered that could help scientists understand why some cancers develop. For the first time, a structure called 'the mesh' has been identified which helps to hold together cells. This discovery changes our understanding of the cell's internal scaffolding.
Human stem cells may improve bone healing in diabetics Adding stem cells from human bone marrow to a broken diabetic bone enhances the repair process, increasing the strength of the newly formed bone. The work could potentially lead to more effective treatments for broken bones.
High risk of sleep apnea in young veterans with PTSD The probability of having a high risk of obstructive sleep apnea increased with increasing severity of PTSD, a new study of young US veterans shows. The study involved 195 Iraq and Afghanistan veterans who visited a Veterans' Affairs outpatient PTSD clinic for evaluation. Results show that 69.2 % had a high risk for sleep apnea, and this risk increased with PTSD symptom
How will astronauts keep in shape for extended periods? Run far or run fast? That is one of the questions NASA is trying to answer with one of its latest studies -- and the answers may help keep us in shape on Earth, as well as in space. Even with regular exercise, astronauts who spend an extended period of time in space experience muscle weakening, bone loss, and decreased cardiovascular conditioning.
Printing 3D graphene structures for tissue engineering . With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many applications in medicine. Now a new ink formulation has been created that allows for the 3-D printing of large, robust graphene structures with unique mechanical and biological properties
Research boosts evidence for a new class of treatments to help preserve vision A substantial percentage of patients with diabetic macular edema do not have high levels of the VEGF protein in the fluid inside their eyes but do have high levels of a protein called PKal (plasma kallikrein) and associated molecules that are key players in an inflammatory molecular pathway involved in the disease, research concludes. This finding could lead to a new class of treatments to help preserve vision.
Hidden hazards found in 'green' products Common consumer products, including those marketed as 'green,' 'all-natural,' 'non-toxic' and 'organic' emit a range of compounds that could harm human health and air quality, researchers have found. But most of these ingredients are not disclosed to the public.Continue Reading
Dairies found illegally using antibiotics A small number of dairy farms have been found using animal antibiotics in ways not approved by law, according to a new study by the U.S. Food and Drug Administration’s Center for Veterinary Medicine. Continue Reading
Onion extract may improve high blood sugar and cholesterol The extract of onion bulb, Allium cepa, strongly lowered high blood glucose (sugar) and total cholesterol levels in diabetic rats when given with the antidiabetic drug metformin, according to a new study.Continue Reading
Study contaminated food causes 14%: of norovirus outbreaks According to new work by researchers from the Netherlands, New Zealand and the U.S. Centers for Disease Control and Prevention about 14 % of all norovirus outbreaks are attributed to contaminated food. Noroviruses are one of the leading causes of gastroenteritis worldwide. Continue Reading
Graphene: A new tool for fighting cavities Dental diseases, which are caused by the overgrowth of certain bacteria in the mouth, are among the most common health problems in the world. Now scientists have discovered that a material called graphene oxide is effective at eliminating these bacteria, some of which have developed antibiotic resistance Continue Reading
