The global escalation in tuberculosis (TB) cases accompanied by the emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains of ( emphasizes the critical requirement for novel potent drugs. The demonstrates extraordinary adaptability, thriving in diverse conditions, and always finds itself in win-win situations regardless of whether the environment is favorable or unfavorable; no matter the magnitude of the challenge, it can endure and survive. This review aims to uncover the role of multiple stress sensors of that assist bacteria in remaining viable within the host for years against various physiological stresses offered by the host.

S-adenosylmethionine (SAM)-dependent histamine N-methyltransferase (HNMT) is a crucial enzyme involved in histamine methylation, playing an important role in the epigenetic modification of biology. It entails the addition of methyl groups to histamine molecules, thereby regulating gene expression, cellular signal transduction, and other biological processes. Therefore, gaining a profound understanding of the detailed mechanism underlying HNMT-mediated methylation reactions is instrumental in elucidating the role of histamine methylation in biology.

Two-dimensional layered materials (2DLMs) have received increasing attention for their potential in bioelectronics due to their favorable electrical, optical, and mechanical properties. The transformation of the planar structures of 2DLMs into complex 3D shapes is a key strategic step toward creating conformal biointerfaces with cells and applying them as scaffolds to simultaneously guide their growth to tissues and enable integrated bioelectronic monitoring. Using a strain-engineered self-foldable bilayer, we demonstrate the facile formation of predetermined 3D microstructures of 2DLMs with controllable curvatures, called microrolls.

Hydrogel-based sensors typically demonstrate conspicuous swelling behavior in aqueous environments, which can severely compromise the mechanical integrity and distort sensing signals, thereby considerably constraining their widespread applicability. Drawing inspiration from the multilevel heterogeneous structures in biological tissues, an antiswelling hydrogel sensor endowed with high strength, rapid self-recovery, and low swelling ratio was fabricated through a water-induced phase separation and coordination cross-linking strategy. A dense heterogeneous architecture was developed by the integration of "rigid" quadridentate carboxyl-Zr coordination bonds and "soft" hydrophobic unit-rich regions featuring π-π stacking and cation-π interactions into the hydrogels.

Deep eutectic solvents (DESs) have attracted significant attention in recent years due to its environment friendly characteristics and its participation in the multi-heteroatom doping of carbon quantum dots (CQDs). In this work, we present a simple, fast, and environment-friendly microwave synthesis approach for the synthesis of DES-assisted nitrogen and chloride co-doped CQDs (N,Cl-CQDs) using a choline chloride-urea based DES. A biomass-based precursor, i.
