Transition metal Si-chalcogenides: a new two-dimensional anode material for Na-ion batteries.

Sodium (Na) ion batteries (SIB) hold great importance in energy storage due to their potential to offer a sustainable and cost-effective alternative to traditional lithium-ion batteries. Na is abundantly available and less expensive than lithium, making it an attractive option for large-scale energy storage applications. In the present work, we have predicted a series of 2D transition metal (TM) Si-chalcogenides (TMSiCs), TMXSi (TM = Ta, Nb and X = S, Se), which exhibit metallic characteristics.

Understanding determinants of lung cancer preventive care in at-risk urban American Indians and Alaska Natives: A mixed-methods study.

Introduction: Lung cancer is the leading cause of cancer death among American Indian and Alaska Native (AI/AN) people, and AI/AN people have the highest rate of smoking of any racial or ethnic group in the US. There is limited research to inform culturally-relevant strategies for lung cancer prevention inclusive of lung cancer screening (LCS). The objective of this study was to understand determinants of LCS and tobacco cessation care in at-risk urban-dwelling AI/ANs.

Development of DNA-Based Lateral Flow Assay for Detection of LDLR Gene Mutation for Familial Hypercholesterolemia.

Background: The techniques for detecting single nucleotide polymorphisms (SNP) require lengthy and complex experimental procedures and expensive instruments that may only be available in some laboratories. Thus, a deoxyribonucleic acid (DNA)-based lateral flow assay (LFA) was developed as a point-of-care test (POCT) diagnostic tool for genotyping. In this study, single nucleotide variation (E101K) in the low-density lipoprotein receptor gene leading to familial hypercholesterolemia (FH) was chosen as a model.

Triplin: Mechanistic Basis for Voltage Gating.

The outer membrane of Gram-negative bacteria contains a variety of pore-forming structures collectively referred to as porins. Some of these are voltage dependent, but weakly so, closing at high voltages. Triplin, a novel bacterial pore-former, is a three-pore structure, highly voltage dependent, with a complex gating process.

Detection of SARS-CoV-2 in Environment: Current Surveillance and Effective Data Management of COVID-19.

Since diagnostic laboratories handle large COVID-19 samples, researchers have established laboratory-based assays and developed biosensor prototypes. Both share the same purpose; to ascertain the occurrence of air and surface contaminations by the SARS-CoV-2 virus. However, the biosensors further utilize internet-of-things (IoT) technology to monitor COVID-19 virus contamination, specifically in the diagnostic laboratory setting.
