Enhancement of Osseointegration via Endogenous Electric Field by Regulating the Charge Microenvironments around Implants.

The regulation of the charged microenvironment around implants is an effective way to promote osseointegration. Although homeostasis of the charged microenvironment plays an integral role in tissues, current research is externally invasive and unsuitable for clinical applications. In this study, functional materials with different surface potential differences are prepared by changing the spatial layout of Ta and Ag on the surface of a Ti-6Al-4V alloy (TC4).

Mitigating Membrane Biofouling in Protein Production with Zwitterionic Peptides.

Biofouling on polymeric membranes poses a significant challenge in protein production and separation processes. We report here on the use of zwitterionic peptides composed of alternating lysine (K) and glutamic acid (E) residues to reduce biomolecular fouling on gold substrates and polymeric membranes within a protein production-mimicking environment. Our findings demonstrate that both gold chips and polymeric membranes functionalized with longer sequence zwitterionic peptides, along with a hydrophilic linker, exhibit superior antifouling performance across various protein-rich environments.

In this study, leveraging the advantages of cell membrane-coated biomimetic nanocarriers, we developed a multifunctional biomimetic nanodelivery system nano-RONS-sacrificial agent for AKI treatment.

LncRNA HOTAIR regulates the expression of MRP1 gene through the mir-6807-5p/Egr1 axis to affect the multidrug resistance of lung cancer cells.

Multi-drug resistance-associated protein 1 (MRP1) plays critical roles in the multi-drug resistance (MDR) of cancer cells, LncRNA HOTAIR is closely related to MDR in lung cancer, however, the effects of HOTAIR on MRP1 expression and MDR in lung cancer cells (A549/DDP) remain unknown. In this study, the effects of HOTAIR on MRP1 gene expression and MDR in A549/DDP cells were monitored. LncRNA HOTAIR was upregulated in A549/DDP cells, and overexpression of HOTAIR promoted MRP1 expression and MDR development.

Chitosan-based injectable porous microcarriers with enhanced adipogenic differentiation and angiogenesis for subcutaneous adipose tissue regeneration.

Chitosan is a promising biomaterial for tissue engineering, but its functionality is limited by a lack of bioactive sites. This study develops chitosan/amniotic membrane microcarriers to enhance vascularization and tissue regeneration for subcutaneous adipose tissue. The incorporation of decellularized amniotic membrane enhances the bioactivities of chitosan in promoting cell differentiation and angiogenesis.

Integration of untargeted lipidomics and targeted metabolomics revealed the mechanism of flavor formation in lightly cured sea bass driven via salt.

Salt enhances flavor and salinity in Chinese curing; however, excessive use can pose health risks, while reducing NaCl may harm taste. This study utilized targeted and untargeted metabolomics to investigate the intrinsic molecular mechanisms that drive flavor formation in cured sea bass subjected to salt. Glycine, succinic acid, lactic acid and uridine significantly contributed to the taste profile of the cured sea bass.

Drp1-Dependent Mitochondrial Fission Contributes to Lactic Acid-Induced Chicken Cardiomyocyte Damage.

Enhanced glycolysis and elevated lactic acid (LA) production are observed during sudden death syndrome (SDS) in broilers. However, the mechanism underlying LA-induced cardiomyocyte damage and heart failure in fast-growing broilers remains unclear. In this study, chicken embryo cardiomyocytes (CECs) were cultured and treated with LA to investigate LA-induced CEC injury and its mechanism, aiming to develop strategies to prevent LA-induced SDS in broilers.

Leaf Dry Matter Content Is Phylogenetically Conserved and Related to Environmental Conditions, Especially Wildfire Activity.

Leaf dry matter content (LDMC) is an important determinant of plant flammability. Investigating global patterns of LDMC could provide insights into worldwide plant flammability patterns, informing wildfire management. We characterised global patterns of LDMC across 4074 species from 216 families, revealing that phylogenetic and environmental constraints influence LDMC.

Nobiletin: a potential erythropoietin receptor activator protects renal cells against hypoxia.

Tangerine peel is a traditional Chinese herb and has been widely applied in foods and medicine for its multiple pharmacological effects. Erythropoietin receptor (EPOR), a member of the cytokine receptor family, is widely expressed in multiple tissues in especial kidney and plays protective effects in adverse physiological and pathological conditions. We hypothesized that it might be EPOR agonists existing in Tangerine peel bring such renal benefits.

Bioinspired thermally conducting packaging for heat management of high performance electronic chips.

Conventional electronic chip packaging generates a huge thermal resistance due to the low thermal conductivity of the packaging materials that separate chip dies and coolant. Here we propose and fabricate a closed high-conducting heat chip package based on passive phase change, using silicon carbide which is physically and structurally compatible with chip die materials. Our "chip on vapor chamber" (CoVC) concept realizes rapid diffusion of hot spots, and eliminates the high energy consumption of refrigeration ordinarily required for heat management.

N2GNet tracks gait performance from subthalamic neural signals in Parkinson's disease.

Adaptive deep brain stimulation (DBS) provides individualized therapy for people with Parkinson's disease (PWP) by adjusting the stimulation in real-time using neural signals that reflect their motor state. Current algorithms, however, utilize condensed and manually selected neural features which may result in a less robust and biased therapy. In this study, we propose Neural-to-Gait Neural network (N2GNet), a novel deep learning-based regression model capable of tracking real-time gait performance from subthalamic nucleus local field potentials (STN LFPs).

Adaptable electro-optic detection of THz radiation using a laser-written bull's-eye antenna.

We report a nonlinear terahertz (THz) detection device based on a metallic bull's-eye plasmonic antenna. The antenna, fabricated with femtosecond laser direct writing and deposited on a nonlinear gallium phosphide (GaP) crystal, focuses incoming THz waveforms within the sub-wavelength bull's eye region to locally enhance the THz field. Additionally, the plasmonic structure minimizes diffraction effects allowing a relatively long interaction length between the transmitted THz field and the co-propagating near-infrared gating pulse used in an electro-optic sampling configuration.

Hotspots of genetic change in Yersinia pestis.

The relative contributions of mutation rate variation, selection, and recombination in shaping genomic variation in bacterial populations remain poorly understood. Here we analyze 3318 Yersinia pestis genomes, spanning nearly a century and including 2336 newly sequenced strains, to shed light on the patterns of genetic diversity and variation distribution at the population level. We identify 45 genomic regions ("hot regions", HRs) that, although comprising a minor fraction of the genome, are hotbeds of genetic variation.
