Hedgehog signaling proteins keep cancer stem cells alive

Jan 19 2018 - 00:01
Researchers from Charité - Universitätsmedizin Berlin have discovered that the survival of cancer stem cells is dependent on the 'Hedgehog signaling pathway'. Targeting this pathway had previously shown no effect on the growth of colorectal cancer. Now, Charité scientists have demonstrated that using different drugs to target a specific aspect of the pathway may yield better treatment outcomes for patients. Results from this research have been published in the journal Cell Reports*.

National school lunch program aces safety test

Jan 19 2018 - 00:01
The National School Lunch Program's (NSLP) strict safety standards work, according to a new University of Connecticut study that found food safety standards for ground beef supplied to the program are highly effective in keeping harmful bacteria out of school lunches nationwide. However, ground beef that fails NSLP inspection can be sold to other vendors, eventually making its way onto consumers' plates, meaning ground beef sold to schools may be the safest on the market.

How metal scaffolds enhance the bone healing process

Jan 19 2018 - 00:01
In cooperation with colleagues from the Wyss Institute at Harvard, researchers from the Julius Wolff Institute, the Berlin-Brandenburg Center for Regenerative Therapies, and Charité's Center for Musculoskeletal Surgery have shown how mechanically optimized constructs known as titanium-mesh scaffolds help optimize bone regeneration. The researchers' findings have been reported in the current issue of Science Translational Medicine*.

Adaptive immune response: New cofactor of roquin identified

Jan 19 2018 - 00:01
Roquin has a key role in the adaptive immune response. It controls the activation and differentiation of T cells and thus helps to make the decisions whether or not and which type of immune response will be mounted. Now, a team of scientists of Helmholtz Zentrum München in cooperation have identified NUFIP2, a protein with a previously unknown function, as cofactor of Roquin and discovered that NUFIP2 enhances Roquin's regulatory function.

Real-world intercontinental quantum communications enabled by the Micius satellite

Jan 19 2018 - 00:01
A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys with ?kHz rate during the passage of the satellite Micius over a ground station. Using Micius as a trusted relay, a secret key is created between China and Europe at locations separated up to 7,600 km on the Earth.

Beyond drugs for IBD: Improving the overall health of IBD patients

Jan 19 2018 - 00:01
1.6 million Americans suffer from IBD. Identifying the best medical treatment leads to improved disease management, but IBD patients also experience mental, emotional and other physical side effects that need to be understood and managed to improve the overall health of IBD patients. Research presented at the Crohn's & Colitis Congress™ helps health care providers understand how to better manage their patients' overall health and mental well-being to increase the quality of their lives.

New strategies to improve the quality of inflammatory bowel disease (IBD) care

Jan 19 2018 - 00:01
1.6 million Americans suffer. As with many chronic conditions, IBD patients often require frequent hospital visits due to rapid changes in their illness and can struggle with finding the balance between their health and their work/social life. Doctors and researchers will come together at the Crohn's & Colitis Congress™ to explore new strategies to improve the care provided to IBD patients, which will ultimately improve patients' quality of life.

New drugs for inflammatory bowel disease (IBD)

Jan 19 2018 - 00:01
1.6 million Americans suffer from IBD. There is no cure for these chronic, life-long conditions. While several effective treatments are available, 40 to 55 percent of patients have no response to current therapies. There is a dire need for new drugs for all patients that are highly safe and effective. Based on research being presented at the Crohn's & Colitis Congress™, we are hopeful that future IBD patients will have new and effective treatment options.

Scientists discover how treating eczema could also alleviate asthma

Jan 19 2018 - 00:01
Scientists from VIB-UGent have discovered insights for a possible new therapy for eczema that also reduces the severity of asthma. The findings are an important next step in understanding the relationship between the two inflammatory diseases and to developing effective therapies. The results of the study are published in the Journal of Investigative Dermatology.

A nanophenomenon that triggers the bone-repair process

Jan 19 2018 - 00:01
Researchers at the Institut Català de Nanociència i Nanotecnologia have resolved one of the great unknowns in bone self-repair: how the cells responsible for forming new bone tissue are called into action. Their work reveals the role of an electromechanical phenomenon at the nanoscale, flexoelectricity, as a possible mechanism for stimulating the cell response and guiding it throughout the fracture repair process.

Factor that doubles the risk of death from breast cancer identified

Jan 19 2018 - 00:01
Researchers at Karolinska Institutet in Sweden have discovered that the risk of death from breast cancer is twice as high for patients with high heterogeneity of the oestrogen receptor within the same tumour as compared to patients with low heterogeneity. The study, published in The Journal of the National Cancer Institute, shows that the higher risk of death is independent of other known tumour markers and also holds true for Luminal A breast cancer.
