For this reason, the observation of such …             Thermal post-treatment alters nutrient release from a controlled-release fertilizer coated with a waterborne polymer ▶     Zijun Zhou, Changwen Du, Ting Li et al.     Controlled-release fertilizers (CRF) use a controlled-release technology to enhance the nutrient use efficiency of crops. Many factors affect the release of nutrients from the …             Bacterial inhibition potential of 3D rapid-prototyped magnesium-based porous composite scaffolds–an in vitro efficacy study ▶     Rui Ma, Yu-xiao Lai, Long Li et al.     Bone infections are common in trauma-induced open fractures with bone defects. Therefore, developing anti-infection scaffolds for repairing bone defects is desirable. This study …             Structural and Thermodynamic Characteristics of Amyloidogenic Intermediates of β-2-Microglobulin ▶     Song-Ho Chong, Jooyeon Hong, Sulgi Lim et al.     β-2-microglobulin (β2m) self-aggregates to form amyloid fibril in renal patients taking long-term dialysis treatment. Despite the extensive structural and mutation studies …             A Simple and Sensitive Method to Quantify Biodegradable Nanoparticle Biodistribution using Europium Chelates ▶     Lindsey Crawford, Jaclyn Higgins, David Putnam     The biodistribution of biodegradable nanoparticles can be difficult to quantify. We report a method using time resolved fluorescence (TRF) from a lanthanide chelate to minimize …             Activation of bacterial channel MscL in mechanically stimulated droplet interface bilayers ▶     Joseph S. Najem, Myles D. Dunlap, Ian D. Rowe et al.     MscL, a stretch-activated channel, saves bacteria experiencing hypo-osmotic shocks from lysis. Its high conductance and controllable activation makes it a strong candidate to …             Effects of Carbon Dioxide Aerosols on the Viability of Escherichia coli during Biofilm Dispersal ▶     Renu Singh, Ajay K. Monnappa, Seongkyeol Hong et al.     A periodic jet of carbon dioxide (CO2) aerosols is a very quick and effective mechanical technique to remove biofilms from various substrate surfaces. However, the impact of the …             Physical Intimacy of Breast Cancer Cells with Mesenchymal Stem Cells Elicits Trastuzumab Resistance through Src Activation ▶     Amita Daverey, Allison P. Drain, Srivatsan Kidambi     The development of resistance to trastuzumab is a major obstacle for lasting effective treatment of patients with ErbB2-overexpressing tumors. Here, we demonstrate that the …             Probing cytochrome c in living mitochondria with surface-enhanced Raman spectroscopy ▶     Nadezda A. Brazhe, Andrey B. Evlyukhin, Eugene A. Goodilin et al.     Selective study of the electron transport chain components in living mitochondria is essential for fundamental biophysical research and for the development of new medical …                 Nature Publishing Group offers a free open access funding support service to enable authors to discover and apply for article processing charge funding available to them.
