Surface-Enhanced Raman Spectroscopy (SERS) Substrates Based on Photonic Crystal Embedded Bi-Metallic Nanoparticles for Leptospiral DNA Detection.

Leptospirosis is an acute bacterial febrile disease affecting humans and animals in many tropical and subtropical countries. This work presents an optimization of surface-enhanced Raman spectroscopy (SERS) substrates to probe vibrational spectroscopic detail from deoxyribonucleic acid (DNA). The pathogenic gene of LipL32 was used as a biomarker.

Synthesis of vanillin oxidation of kenaf stalks in the presence of CeO: tuning the catalytic behaviour of CeO nanostructure morphology.

Different CeO nanostructures were synthesized using a hydrothermal method and treated with alkaline NaOH, followed by drying at 120 °C for 16 h and calcined at 400 °C for the direct oxidation of kenaf stalks to vanillin under microwave irradiation. The catalysts were characterized for their physicochemical properties using XRD, BET, Raman spectroscopy, TPR, TPO, and XPS. All synthesized CeO nanostructures show diffraction peaks corresponding to the formation of cubic fluorite, which agrees with Raman spectra of the F mode.

Antifungal activity of synthetic xanthenone against fluconazole-resistant Candida auris and its mechanism of action.

Candida auris, an emerging multidrug-resistant fungal pathogen discovered in Japan in 2009, poses a significant global health threat, with infections reported in about 25 countries. The escalation of drug-resistant strains underscores the urgent need for new treatment options. This study aimed to investigate the antifungal potential of 2,3,4,4a-tetrahydro-1H-xanthen-1-one (XA1) against C.

Impact of spatial separation for respiratory patients on emergency department flow process intervals and length of stay.

Background: Spatial separation in emergency departments (EDs) is empirically practised as part of transmission-based precaution. Despite its potential benefits in segregating potentially infectious patients, the effects of spatial separation on patient flow remain uncertain.

Aim: To explore the impact of spatial separation on ED patient flow and to identify specific clinical factors and flow process intervals (FPIs) influencing ED length of stay (EDLOS).

Ce-Zr-based mixed oxide catalyst for oxidative depolymerization of kenaf stalk (biomass) into vanillin.

Since petroleum became depleted, rapid attention has been devoted to renewable energy sources such as lignocellulosic biomass to produce useful chemicals for industry (for instance vanillin). Three primary components of lignocellulose are lignin, cellulose, and hemicellulose. This paper uses microwave-assisted technology to oxidize the kenaf stalk (lignocellulosic biomass) and extract lignin to produce vanillin.
