Superabsorbent, antibacterial, and antioxidant nanocellulose aerogels: Preparation, characterization, and application in beef preservation.

Herein, we prepared a new aerogel-based preservation pad using soy hull nanocellulose (SHNC), polyvinyl alcohol (PVA), whey protein isolate (WPI), and cinnamon essential oil (CEO) as raw materials. The physicochemicals of the aerogel preservation pads were studied, and their effects on beef preservation were evaluated. The results showed that the aerogel monomers were crosslinked by hydrogen, ester bonds, and electrostatic interactions in the aerogels, and there were three-dimensional pores in the aerogels.

A novel aptamer-based photoelectrochemical sensor for zearalenone detection: Integration of g-CN/BiOBr with in situ growth AgS quantum dots.

Zearalenone (ZEN), a secondary metabolite mycotoxin primarily synthesized by Fusarium species and prevalent in cereal grains, exerts estrogenic effects that could induce reproductive toxicity and teratogenic outcomes. To enhance the precision of ZEN detection, we have developed an innovative photoelectrochemical (PEC) aptamer-based sensor employing in situ growth silver sulfide (AgS) quantum dots-sensitized graphitic carbon nitride/bismuth oxybromide (g-CN/BiOBr) heterojunction. The g-CN/BiOBr composite exhibits robust structural stability and straightforward synthesis.

PLAC1 augments the malignant phenotype of cervical cancer through the mTOR/HIF-1α/Snail signaling pathway.

Myosin-binding protein 13 mediates primary seed dormancy via abscisic acid biosynthesis and signaling in Arabidopsis.

Dormancy is an essential characteristic that enables seeds to survive in unfavorable conditions while germinating when conditions are favorable. Myosin-binding proteins (MyoBs) assist in the movement of organelles along actin microfilaments by attaching to both organelles and myosins. In contrast to studies on yeast and metazoans, research on plant MyoBs is still in its early stages and primarily focuses on tip-growing cells.

Genetically encoded green fluorescent sensor for probing sulfate transport activity of solute carrier family 26 member a2 (Slc26a2) protein.

Genetically encoded fluorescent biosensors became indispensable tools for biological research, enabling real-time observation of physiological processes in live cells. Recent protein engineering efforts have resulted in the generation of a large variety of fluorescent biosensors for a wide range of biologically relevant processes, from small ions to enzymatic activity and signaling pathways. However, biosensors for imaging sulfate ions, the fourth most abundant physiological anion, in mammalian cells are still lacking.

Novel Electrochemical Sensor Based on One-Step Encapsulation of Metal-Organic Framework (MOF) for Simultaneous Detection of SARS-CoV and SARS-CoV-2.

This study investigates three metal-organic frameworks (MOFs) with distinct Brunauer-Emmett-Teller (BET) surface areas and pore sizes: MOF (1274 m/g, <0.7 nm), MOF (371 m/g, 1.5 nm), and MOF (1917 m/g, 2 nm).

NeIle, a Genetically Encoded Indicator for Branched-Chain Amino Acids Based on mNeonGreen Fluorescent Protein and LIVBP Protein.

Branched-chain amino acids (BCAAs) play an important role in the functioning of mammalian cells and the central nervous system. However, available genetically encoded indicators for BCAAs are based on Förster resonance energy transfer and have a limited dynamic range. We developed a single fluorescent protein-based sensor for BCAAs, called NeIle, which is composed of circularly permutated mNeonGreen protein inserted into the leucine-isoleucine-valine binding protein (LIVBP) from bacteria.

Rab3B Proteins: Cellular Functions, Regulatory Mechanisms, and Potential as a Cancer Therapy Target.

RAB3 proteins, a pivotal subgroup within the Rab protein family, are known to be highly expressed in brain and endocrine gland tissues, with detectable levels also observed in exocrine glands, adipose tissue, and other peripheral tissues. They play an indispensable role in the trafficking of cellular products from the endoplasmic reticulum (ER) to the Golgi apparatus and ultimately to secretory vesicles, participating in vesicle transport, mediating cell membrane adhesion, and facilitating membrane fusion during exocytosis. Among these, Rab3B, a specific subtype of RAB3, is a low-molecular-weight (approximately 25 kD) GTP-binding protein (GTPase) characterized by its typical GTPase fold, composed of seven β-strands (six parallel and one antiparallel) surrounded by six α-helices.

Anomalous Raman Response in 2D Magnetic FeTe Under Uniaxial Strain: Tetragonal and Hexagonal Polymorphs.

2D Fe-chalcogenides emerge with rich structures, magnetisms, and superconductivities, which spark the growing research interests in the torturous transition mechanism and tunable properties for their potential applications in nanoelectronics. Uniaxial strain can produce a lattice distortion to study symmetry breaking induced exotic properties in 2D magnets. Herein, the anomalous Raman spectrum of 2D tetragonal (t-) and hexagonal (h-) FeTe is systematically investigated via uniaxial strain engineering strategy.

Melatonin alleviates LPS-induced depression-like behavior in mice by inhibiting ferroptosis by regulating RNA methylation-mediated SIRT6/Nrf2/HO-1 pathway.

Purpose: The objective of this study is to investigate the impact of ferroptosis on depression and elucidate the molecular mechanism underlying melatonin's inhibitory effect on ferroptosis in the treatment of depression.

Methods: In this study, a depression-like behavior model was induced in mice using LPS, and the effect of melatonin on depression-like behavior was evaluated through behavioral experiments (such as forced swimming test (FST) and sucrose preference test (SPT)). Additionally, molecular biological techniques (including real-time fluorescence quantitative PCR, Western blotting, immunoprecipitation) were employed to detect the expression levels and interactions of METTL3, SIRT6 and ferroptosis-related genes in mouse brain tissue.

Exploring the influence of different enzymes on soy hull polysaccharide emulsion stabilization: A study on interfacial behavior and structural changes.

The interfacial behavior of soy hull polysaccharide (SHP) at the oil-water interface and the stabilization mechanism of high internal phase emulsion (HIPE) with three enzymes (α-amylase, trypsin and papain) were investigated. The diameter of the α-amylase-treated emulsion was the minimum at 40 min, indicating that the carbohydrate portions of SHP form a thick layer on the surface of the droplet to prevent aggregation. Moreover, Raman spectroscopy revealed significantly higher levels of disordered content of SHP emulsion treated with α-amylase at 60 min, potentially affecting the directional movement of SHP molecules in the emulsion.
