In this study, we investigate the catalytic performance of molybdenum sulfide (MoS) modified with either nickel (Ni) or platinum (Pt) nanoparticles as catalysts for the hydrogen evolution reaction (HER). The MoS was prepared on the TiO nanotube substrates via a facile hydrothermal method, followed by the deposition by magnetron sputtering of Ni or Pt nanoparticles on the MoS surface. Structural and morphological characterization confirmed the successful incorporation of Ni or Pt nanoparticles onto the MoS support.

In breast cancer, fibrosis is a histopathologic criterion for invasive cancer and poor survival that results from inflammatory factors and remodeling of the extracellular matrix to produce an immune tolerant microenvironment. To determine whether tolerance is associated with the immune checkpoint, Programmed Cell Death 1 (PD-1), NeuT/ATTAC mice, a conditional model of mammary fibrosis that we recently developed, were administered a murine-specific anti-PD-1 mAb related to pembrolizumab, and drug response was monitored by tumor development, imaging mass cytometry, immunohistochemistry and tumor gene expression by RNAseq.

Methods: In this multicenter, randomized, double-blind, double-dummy study, 127 young children aged 1-5 years with hypertension (MSBP ≥95th percentile) were randomized (1:1) to receive valsartan 0.25 or 4 mg/kg/day for 6 weeks, followed by a 20 week open-label phase, where patients received valsartan 1 mg/kg/day for 4 weeks, and then optionally titrated to 2 mg/kg/day or up to 4 mg/kg/day.
