Curcumin-loaded cockle shell-derived calcium carbonate nanoparticles ameliorates lead-induced neurotoxicity in rats via attenuation of oxidative stress.

A substantial global health burden is associated with neurotoxicity caused by lead (Pb) exposure and the common mechanism of this toxicity is mainly via oxidative damage. Curcumin has remarkable pharmacological activities but remains clinically constrained due to its poor bioavailability when orally administered. Currently, cockle shell-derived calcium carbonate nanoparticle (CSCaCONP) is gaining more acceptance in nanomedicine as a nanocarrier to various therapeutics.

Emerging application of biochar as a renewable and superior filler in polymer composites.

Biochar is conventionally and widely used for soil amendment or as an adsorbent for water treatment. Nevertheless, the need for transition to renewable materials has resulted in an expansion of biochar for use as a filler for polymer composites. The aim is to enhance the physical, chemical, mechanical and rheological properties of the polymer composite.

Humoral immunological kinetics of severe acute respiratory syndrome coronavirus 2 infection and diagnostic performance of serological assays for coronavirus disease 2019: an analysis of global reports.

As the coronavirus disease 2019 (COVID-19) pandemic continues to rise and second waves are reported in some countries, serological test kits and strips are being considered to scale up an adequate laboratory response. This study provides an update on the kinetics of humoral immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and performance characteristics of serological protocols (lateral flow assay [LFA], chemiluminescence immunoassay [CLIA] and ELISA) used for evaluations of recent and past SARS-CoV-2 infection. A thorough and comprehensive review of suitable and eligible full-text articles was performed on PubMed, Scopus, Web of Science, Wordometer and medRxiv from 10 January to 16 July 2020.

Comparative Analysis of Private Retail Community Pharmacies' Participation in the National Health Insurance Scheme of Nigeria and Ghana: Implications for Access to Essential Medicines.

Background: Frequent stock-out of drugs in the public hospitals causes National Health Insurance Scheme (NHIS) enrollees to purchase most of their medicines out-of-pocket in community pharmacies, thereby imposing financial constraints on them against the main objective of the scheme. The objectives of this study were to determine and compare the level of participation of private retail community pharmacies (PRCPs) in the NHIS of Nigeria and Ghana, to describe their spatial distribution, and to highlight from literature major factors that would influence the participation of these pharmacies in the scheme.

Methods: PRCPs data were collected from the Nigerian NHIS active secondary healthcare providers list of 1st July 2017 and the Ghanaian NHIS active providers online list of 2018.
