Transcriptional responses of three slc39a/zip members (zip4, zip5 and zip9) and their roles in Zn metabolism in grass carp (Ctenopharyngodon idella).

In order to explore the regulatory mechanism of zip4, zip5 and zip9 in zinc metabolism of grass carp (Ctenopharyngodon idella), the effects of zinc (Zn) on the mRNA expression of zip4, zip5 and zip9 were investigated. Compared to the control, the mRNA levels of zip4 and zip9 were significantly reduced under low and high zinc in L8824 cells; the mRNA expression level of zip5 was significantly increased under low and high zinc incubation. Then, their promoter sequences were cloned, which were 2361 bp, 2004 bp and 2186 bp sequences for zip4, zip5 and zip9 promoters, respectively.

Disinfection by-product formation potential in response to seasonal variations in lake water sources: Dependency on fluorescent and molecular weight characteristics.

Seasonal fluctuations present significant challenges to drinking water treatment by altering the properties of Dissolved Organic Matter (DOM) within watersheds, thereby influencing the potential for disinfection by-product (DBP) formation. DOM is a complex mixture of organic matter that serves as a critical DBP precursor and is closely linked to adverse health outcomes. The prediction of DBP formation is complicated by the variability in DOM concentrations and compositions in lake source water, a situation exacerbated by seasonal changes in water systems.

A trinity STING-activating nanoparticle harnesses cancer cell STING machinery for enhanced immunotherapy.

The cGAS-STING axis is a promising therapeutic target against cancer. However, most activators require STING signaling in the host, especially within antigen-presenting cells, which are rare in a cold tumor microenvironment. The cGAS-STING cascade is also present within cancer cells but with suppressed activity.

"Anchoring Capture" Effect Mimicking Proline in Hardy Deep-Sea Fish to Stabilize the Zinc Anode with Lower Operating Temperature.

The low plating/stripping efficiency of zinc anodes, dendrite growth, and high freezing points of aqueous solutions hinder the practical application of aqueous zinc-ion batteries. This paper proposes a zwitterionic permeable network solid-state electrolyte based on the "anchor-capture" effect to address these problems by incorporating proline (Pro, a biological antifreeze agent) into the electrolyte. Extensive validation tests, Quantum Chemistry (QC) calculations, Molecular Dynamics (MD) Simulations, and ab initio molecular dynamics simulations consistently indicate that the amino groups in proline adsorb onto the Zn metal surface, stabilizing the zinc anode-electrolyte interface, suppressing side reactions from water decomposition, and homogenizing zinc-ion flux.

Organoelectrocatalytic cyclopropanation of alkenyl trifluoroborates with methylene compounds.

Cyclopropanes are not only privileged motifs in many natural products, agrochemicals, and pharmaceuticals, but also highly versatile intermediates in synthetic chemistry. As such, great effort has been devoted to the cyclopropane construction. However, novel catalytic methods for cyclopropanation with two abundant substrates, mild conditions, high functional group tolerance, and broad scope are still highly desirable.

Improving Triethylamine-Sensing Performance of WO Nanoplates through In Situ Heterojunction Construction.

Surface engineering techniques can be used to develop high-performance gas sensing materials and advance the development of sensors. In this study, we improved the gas sensing performance of two-dimensional (2D) WO nanoplates by combining surface Zn modification and the in situ formation of ZnWO/WO heterojunctions. Introducing Zn atoms by surface modification can reconstruct the atomic surface of 2D WO nanoplates, creating additional active sites.

Zinc-Ferricyanide Flow Batteries Operating Stably under -10 °C.

Alkaline ferri/ferro-cyanide-based flow batteries are well suited for energy storage because of their features of high electrochemical activity, good kinetics and low material cost.

How mitochondrial dynamics imbalance affects the progression of breast cancer:a mini review.

Despite the high incidence of breast cancer in women worldwide, there are still great challenges in the treatment process. Mitochondria are highly dynamic organelles, and their dynamics involve cellular energy conversion, signal conduction and other processes. In recent years, an increasing number of studies have affirmed the dynamics of mitochondria as the basis for cancer progression and metastasis; that is, an imbalance between mitochondrial fission and fusion may lead to the progression and metastasis of breast cancer.

DMXL2 Is Required for Endocytosis and Recycling of Synaptic Vesicles in Auditory Hair Cells.

Ribbon synapses of inner hair cells (IHCs) are uniquely designed for ultrafast and indefatigable neurotransmission of the sound. The molecular machinery ensuring the efficient, compensatory recycling of the synaptic vesicles (SVs), however, remains elusive. This study showed that hair cell knock-out of murine , whose human homolog is responsible for nonsyndromic sensorineural hearing loss DFNA71, resulted in auditory synaptopathy by impairing synaptic endocytosis and recycling.

The construction of a prognostic model by apoptosis-related genes to predict survival, immune landscape, and medication in cholangiocarcinoma.

Background: Cholangiocarcinoma (CCA) is a highly aggressive and invasive malignant tumor of the bile duct, with a poor prognosis and a high mortality rate. Currently, there is a lack of effective targeted treatment methods and reliable biomarkers for prognosis.

Methods: We downloaded RNA-seq and clinical data of CCA from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases as training and test sets.

Modal Parameter Recursive Estimation of Concrete Arch Dams under Seismic Loading Using an Adaptive Recursive Subspace Method.

Modal parameter estimation is crucial in vibration-based damage detection and deserves increased attention and investigation. Concrete arch dams are prone to damage during severe seismic events, leading to alterations in their structural dynamic characteristics and modal parameters, which exhibit specific time-varying properties. This highlights the significance of investigating the evolution of their modal parameters and ensuring their accurate identification.

Thermosensitive Micelles Gel to Deliver Quercetin Locally for Enhanced Antibreast Cancer Efficacy: An In Vitro Evaluation.

Although quercetin is low cytotoxicity to normal human cells, quercetin is effective against the growth of some tumors. Given the poor blood stability in vivo, insolubility, low delivery efficiency, and poor medicinal properties of quercetin, we developed a local drug delivery system comprising quercetin core's polymer micelles and F127 hydrogel stroma. In vitro evaluation revealed that quercetin core's polymer micelles have excellent antitumor activity and could inhibit the multiplication of 4T1 breast cancer cells through the apoptosis pathway.

The risk of viable but non-culturable (VBNC) enterococci and antibiotic resistance transmission during simulated municipal sludge composting.

Sludge composting is a sludge resource utilization method that can reduce pollutants, such as pathogens. Enterococci are regarded as more reliable and conservative indicators of pathogen inactivation than fecal coliforms, which are typically used as indicators of fecal pollution. Non-spore pathogenic bacteria may enter a viable but non-culturable (VBNC) state during composting, leading to residual risk.

Control of chlorination disinfection by-products in drinking water by combined nanofiltration process: A case study with trihalomethanes and haloacetic acids.

Enhancing Extracellular Electron Transfer of a 3D-Printed Bioanode with Riboflavin-Modified Carbon Black Bioink.

3D printing of a living bioanode holds the potential for the rapid and efficient production of bioelectrochemistry systems. However, the ink (such as sodium alginate, SA) that formed the matrix of the 3D-printed bioanode may hinder extracellular electron transfer (EET) between the microorganism and conductive materials. Here, we proposed a biomimetic design of a 3D-printed bioanode, wherein riboflavin (RF) was modified on carbon black (CB) to serve as a redox substance for microbial EET.
