Preparation of chitosan/lignin nanoparticles-based nanocomposite films with high-performance and improved physicochemical properties for food packaging applications.

Chitosan (CH)-based composite films have attracted increasing attention as promising green food packaging materials due to their biodegradability and ease of fabrication. Additionally, lignin (LN) has been widely used as additive for chitosan-based films to improve their physicochemical properties. In this study, a series of composite films made of chitosan nanoparticles (NCH) as a matrix and alkali lignin nanoparticles (LNPs) as functional filler were prepared.

[Simultaneous Quadruple Therapy In The Treatment Of Helicobacter Pylori During Peptic Ulcer Disease].

Unlabelled: Helicobacter pylori (Hp) infection plays an important role in the genesis of peptic ulcer disease. In the absence of susceptibility testing, concomitant quadruple therapy is one of the most widely used eradication methods. In the absence of a study on four-drug therapy and the difficulty of studying antibiotic susceptibility in our context, we initiated this work in order to evaluate the efficacy of an empirical treatment with concomitant four-drug therapy currently available.

Cross sectional survey of maternal and newborn quality of care in Niger: Selected findings, lessons learned and recommendations.

Comprehensive assessments of quality of care (QoC) are essential for monitoring progress towards meeting global and national maternal and newborn health (MNH) targets. Liverpool School of Tropical Medicine (LSTM) and the Niger Ministry of Public Health adapted a 2014 WHO QoC tool to cover antenatal care (ANC) and postnatal care (PNC) and include client voices through exit interviews. The objectives of the study were to assess quality of MNH care in Niger and to document lessons learnt from implementing the LSTM QoC tool.

Synthesis and Magnetic Properties of Spherical Maghemite Nanoparticles with Tunable Size and Surface Chemistry.

We report the synthesis of uniform populations of spherical maghemite nanoparticles by thermal decomposition of iron precursors with tunable diameters centered at 3.3, 7.5, and 12.
