 | | |  Australian researchers have unlocked the mystery as to why the chemotherapy drug 5-Fluorouracil (5-FU) is not effective at treating certain cancers and have claimed a breakthrough in boosting its efficacy. The research could potentially lead to a laboratory test that could flag up resistance to the drug and thereby reduce unnecessary chemotherapy treatments. | | | | |  Proteins are biological high-performance machines. They can be found in every cell and play an important role in human blood coagulation or as main constituents of hairs or muscles. The function of these molecular tools is obvious from their structure. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a new method to predict this protein structure with the help of artificial intelligence. | | | | |  In ESR, a spin label is added to the target site using cysteine substitution. This is followed by modifying the sulfhydryl group with a paramagnetic nitroxide reagent. The ESR then provides information about the mobility of nitroxide side chain, accessibility of the solvent, distance between nitroxide and other paramagnetic centers. | | | | |  Chronic obstructive pulmonary disease (COPD) is a medical condition where damage to the airway leads to a chronic inflammatory response. In this case study, scientists from Peking and Shanghai identified novel protein biomarkers from exhaled air condensate provided by patients with COPD. These samples were analyzed by liquid chromatography coupled to mass spectrometry (LC-MS). | | | | |  Tel Aviv University and Sheba Medical Center researchers say they have discovered why more than half of patients with metastatic melanoma do not respond to immunotherapy cancer treatments. | |
