Objectives: The 2022 global outbreak of monkeypox virus (MPXV), previously confined to Central and West Africa, necessitates an enhanced understanding of its spread. Comprehensive genomic surveillance to understand the virus's evolution and spread is needed, particularly in Asia.
Methods: Genomic data from 169 MPXV genome sequences in Asia were analysed. Through advanced genomic sequencing of clinical samples, we analysed the distribution and mutations of MPXV lineages in Asia.
Results: Phylogenetic analysis revealed a distinct clustering of C.1 strains rise in Northeast Asia in 2023, while genomic examination identified specific consensus mutations like R84K, R665C and L16F in C.1 strains. The mutations, coupled with an increased rate of apolipoprotein B mRNA-editing catalytic polypeptide-like 3 motif G-to-A mutations in C.1 (OR 24.87±8.81), indicate a potential adaptation mechanism.
Conclusions: Our findings underscore the need for ongoing surveillance and provide vital insights into MPXV's evolving dynamics, aiding in public health strategy formulation against this emerging infectious threat.

N-Heterocyclic Carbene Deposition on a Copper Powder Surface Using Mechanochemistry.

Metal powders are crucial precursors for manufacturing surfaces through thermal spraying, cold spraying, and 3D printing methods. However, surface oxidation of these precursors poses a challenge to the coherence of the metallic materials during manufacturing processes. Herein, we introduce a method for surface modification of copper powder with N-heterocyclic carbenes (NHCs) using mechanochemistry to mitigate surface oxidation.

The proliferation of micro/nanoplastics (MNPs) has emerged as a pivotal environmental issue, largely due to their potential for human exposure. Consequently, the development of sensitive and efficient detection methodologies is paramount for elucidating their environmental footprint. Here, we report a novel three-dimensional (3D) surface-enhanced Raman scattering (SERS) sensor, which integrate TiCT/TiO/WO semiconductor heterostructure, for the rapid and sensitive detection of MNPs in environmental matrices.

Department of Geology, R R Lalan College, Bhuj, India.
The Great Rann of Kachchh is a sabkha terrain with a thick succession of Quaternary to Late Holocene sediments, deposited during high sea level after the Last Glacial Maxima. Geomorphologically, the Great Rann of Kachchh is subdivided into Bet Zone, Linear Trench Zone, Great Barren Zone, and Banni Plain. The Bet zone is a slightly elevated flat surface comprising a complex network of bets and interbet channels-the geomorphic entities developed as complex interplay of sea level and coseismic tectonic activity during the Holocene.

Volatile organic compounds (VOCs) are an ever-growing hazard for health and environment due to their increased emissions and accumulation in the air. Quantum cascade laser-based infrared (QCL-IR) sensors hold significant promise for gas monitoring, thanks to their compact, rugged design, high laser intensity, and high molecule-specific detection capabilities within the mid-infrared spectrum's fingerprint region. In this work, tunable external cavity QCLs were complemented by an innovative germanium-on-silicon integrated optics waveguide sensing platform with integrated microlenses for efficient backside optical interfacing for the tunable laser spectrometer.
