Background: Selective mutism (SM) is a childhood onset anxiety disorder, and the main symptom is not speaking in certain social situations. Knowledge about the duration and long-term outcomes of SM have been lacking and the aim of this systematic literature review was to address this gap in the literature. We investigated how long SM symptoms persisted as well as other psychiatric outcomes associated with SM in later life.

The global emergence of methicillin-resistant (MRSA) that unsusceptible to a wide selection of antimicrobial agents and any newly introduced antimicrobial over the past decades has triggered more extensive holistic measures to put an end to this situation. Molecular surveillance of MRSA clones is important to understand their evolutionary dynamics for investigating outbreaks, propagating precautionary measures, as well as planning for appropriate treatment. This review includes peer-reviewed reports on the molecular characterisation of clinical isolates within Malaysian hospitals from year 2008 to 2020.

Chlorine gas is extensively utilised in industries as both a disinfectant and for wastewater treatment. It has a pungent and irritating odour that is comparable with that of bleach and can cause serious health issues such as headaches and breathing difficulties. Hence, efficiently, and accurately monitoring chlorine gas is critical to ensure that no undesirable incidents occur.

Inspired by nature, cellulose extracted from plant wastes has been explored, due to its great potential as an alternative for synthetic fiber and filler that contributes to structural performance. The drive of this study was to extract, treat, and evaluate the characteristics of rice straw (RS) ( L.) cellulose as a biodegradable reinforcement to be utilized in polymer base materials.

Article Synopsis
  • Residual hemicellulose in cellulose nanofibers (CNF) can prevent agglomeration and aid in faster processing, but its impact on CNF's reinforcement abilities in materials like polypropylene (PP) is uncertain.
  • Two types of CNF were studied: one with about 11% hemicellulose (SHS-CNF) and another with complete removal of hemicellulose (KOH-CNF), both showing similar increases in mechanical properties when incorporated into PP.
  • The study found that having some hemicellulose did not significantly alter the CNF properties, suggesting that less intensive processing for CNF preparation could lead to more sustainable nanocomposite production.
