Dimension-engineered synthesis of atomically thin II-VI nanoplatelets (NPLs) remains an open challenge. While CdSe NPLs have been made with confinement ranging from 2 to 11 monolayers (ML), CdTe NPLs have been significantly more challenging to synthesize and separate. Here we provide detailed mechanistic insight into the layer-by-layer growth kinetics of the CdTe NPLs.

Introduction: Fetal scalp blood sampling (FSBS) can be used as an adjunctive test, in the presence of a pathological intrapartum fetal heart rate trace, to provide evidence of fetal acidaemia. The role of FSBS remains controversial, this study evaluates the diagnostic accuracy of FSBS at determining various adverse neonatal outcomes.

Method: A retrospective cohort analysis of FSBS undertaken < 1 h from birth in a single UK centre in 2016 and 2017.

Objectives: To explore outcomes after tibial rigid intramedullary nailing (RIMN) in skeletally immature patients, with a focus on post-operative complications and iatrogenic changes in tibial slope due to anterior physeal arrest.

Methods: Design: Retrospective case series.

Setting: A large, tertiary care health system in the rural Mid-Atlantic United States, including two Level 1 trauma centers and one Level 2 trauma center.

Fertilizing maize at an optimum nitrogen rate is imperative to maximize productivity and sustainability. Using a combination of long-term (n = 379) and short-term (n = 176) experiments, we show that the economic optimum nitrogen rate for US maize production has increased by 2.7 kg N ha yr from 1991 to 2021 (1.

This study introduces novel cospray-dried (Co-SD) formulations of simvastatin, a Nrf2 activator ROCK inhibitor, with l-carnitine as molecular mixtures in various molar ratios for targeted pulmonary inhalation aerosol delivery in pulmonary hypertension, optimized for excipient-free dry powder inhalers (DPIs). The two components were spray-dried at various molar ratios by using different starting feed solution concentrations and process parameters. In addition to comprehensive physicochemical characterization, in vitro aerosol dispersion performance as DPIs using two FDA-approved DPI devices with different shear stress properties, in vitro viability as a function of dose on 2D human pulmonary cellular monolayers and on 3D small airway epithelia human primary cultures at the air-liquid interface (ALI), and in vitro transepithelial electrical resistance (TEER) at the ALI were conducted.
