Enantiodivergent Synthesis of Both ()- and ()-Heteroaryl Aldols by Rationally Engineered Aldolases.

Aldolases, especially 2-deoxyribose-5-phosphate aldolase (DERA) enzymes, have been widely employed to access key chiral precursors for various active pharmaceutical ingredients (APIs). This has been enabled by expanding their substrate scope toward non-natural acceptors and donors via protein engineering. In this study, we endeavored to broaden the acceptor substrate scope of DERA from sp.

Secure channel estimation model for cognitive radio network physical layer security using two-level shared key authentication.

Physical Layer Security (PLS) in Cognitive Radio Networks (CRN) improves the confidentiality, availability, and integrity of the external communication between the devices/ users. The security models for sensing and beamforming reduce the impact of adversaries such as eavesdroppers in the signal processing layer. To such an extent, this article introduces a Secure Channel Estimation Model (SCEM) using Channel State Information (CSI) and Deep Learning (DL) to improve the PLS.

MoS nanoflowers surface decorated with CuS nanorods and carbon dots for fluorescent and ultrasound imaging in cancer therapy.

In recent years, the design of various ultrasound responsive echogenic nanomaterials offers many advantages such as deep tissue penetration, high signal intensity, colloidal stability, biocompatibility and less expensive for ultrasound-based cancer cell imaging while providing the option to monitor the progress of tumor volume during the treatment. Further, the ability of nanomaterials to combine photo-thermal therapy (PTT) and chemotherapy has opened a new avenue in the development of cancer theranostics for synergistic cancer therapy. Herein, we report MoS nanoflowers (NFs) surface decorated with CuS nanorods (NRs) and folic acid-derived carbon dots (FACDs) using cystine-polyethyleneimine (PEI) linker for PTT-chemotherapy.

Rapid Synthesis of Carbon-Supported Ru-RuO₂ Heterostructures for Efficient Electrochemical Water Splitting.

Development of high-performance electrocatalysts for water splitting is crucial for a sustainable hydrogen economy. In this study, rapid heating of ruthenium(III) acetylacetonate by magnetic induction heating (MIH) leads to the one-step production of Ru-RuO₂/C nanocomposites composed of closely integrated Ru and RuO₂ nanoparticles. The formation of Mott-Schottky heterojunctions significantly enhances charge transfer across the Ru-RuO interface leading to remarkable electrocatalytic activities toward both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in 1 m KOH.

Unraveling the Mysteries of Sleep: Exploring Phylogenomic Sleep Signals in the Recently Characterized Archaeal Phylum Lokiarchaeota near Loki's Castle.

Sleep is a universally conserved behavior whose origin and evolutionary purpose are uncertain. Using phylogenomics, this article investigates the evolutionary foundations of sleep from a never before used perspective. More specifically, it identifies orthologs of human sleep-related genes in the Lokiarchaeota of the Asgard superphylum and examines their functional role.

Microwave-synthesized NiZrO@GNP and NiZrO3@MWCNT nanocomposites: enhanced antimicrobial efficacy against biofilms and .

Unlabelled: The persistent challenge posed by antibiotic-resistant bacteria and tuberculosis necessitates innovative approaches to antimicrobial treatment. This study explores the synthesis and characterization of NiZrO₃ nanoparticles integrated with graphene nanoplatelets (GNP) and multi-walled carbon nanotubes (MWCNT), using a microwave-assisted green synthesis route, employing fenugreek () seed extract as a gelling agent. The synthesised nanocomposites were systematically analyzed using XRD, FT-IR, Raman spectroscopy, HR-SEM and HR TEM analysis to assess structural, optical, and morphological properties.

Fluorescent N-Doped Carbon Dots as a Biocompatible Sensor for Thiophanate-Methyl Detection.

An eco-friendly nitrogen-passivated carbon dot (N-CDs)-based fluorescent sensor was designed for the selective and sensitive detection of thiophanate-methyl, a widely applied fungicide in agriculture. The synthesized N-CDs exhibited robust fluorescence and remarkable photostability, which contributed to the sensor's performance. Notably, the sensor achieved a detection limit as low as 4.

Molecular and Functional Significance of Growth Differentiation Factor-15: A Review on Cardiovascular-Kidney-Metabolic Biomarker.

Cardiovascular-kidney-metabolic (CKM) syndrome is the association between obesity, diabetes, CKD (chronic kidney disease), and cardiovascular disease. GDF-15 mainly acts through the GFRAL (Glial cell line-derived neurotrophic factor Family Receptor Alpha-Like) receptor. GDF-15 and GDFRAL complex act mainly through RET co-receptors, further activating Ras and phosphatidylinositol-3-kinase (PI3K)/Akt pathways through downstream signaling.
