Article Abstract
A neuroanatomical minimal network model was revisited to elucidate the mechanism of salt concentration memory-dependent chemotaxis observed in memorizes the salt concentration during cultivation, manifesting a pronounced taste preference for this concentration. The right-side head sensory neuron, designated ASER, exhibits a response to a decrease in salt concentration. The basal level of glutamate transmission from ASER has been demonstrated to transiently increase and decrease when the current environmental salt concentrations are lower and higher, respectively, than that during previous cultivation. Given the sensitivity of excitatory/inhibitory glutamate receptors expressed on the postsynaptic AIY interneurons, it can be anticipated that the ASER-AIY synaptic transmission will undergo a reversal due to alterations in the basal glutamate release. The neural network, derived from the hypothesis, reproduced the salt concentration memory-dependent preference behavior and revealed that the circuit downstream of ASE functions as a module that is responsible for salt klinotaxis.

Understanding hydrogen bonding and ion-specific interactions in water, sodium sulfate (NaSO), and acetonitrile (ACN) systems remains challenging due to their complex, dynamic nature. Here, Raman spectroscopy is employed to probe hydrogen bonding networks and ion reorganization in NaSO aqueous solutions with different ACN concentrations. The results indicate that, at low ACN concentrations in the ternary solutions, hydrogen bonding between ACN and water molecules disrupts the original hydration structure of the ions, resulting in the formation of small ion clusters via electrostatic interactions.

Case History: In 2023, 160/245 (65%) 2-year-old KiwiCross dairy heifers from a seasonally calving Otago herd developed severe granular vulvovaginitis after calving.
Clinical Findings: Affected heifers presented 3-12 days post-calving with tail elevation, vaginal discharge and, in most cases, vulval swelling. Heifers were afebrile although some were inappetent.

Monoclonal antibodies (mAb) have transformed modern medicine, offering targeted therapies for cancer, autoimmune disorders, and infectious diseases. To enhance patient convenience, subcutaneous administration is increasingly prioritized, requiring highly concentrated formulations. However, high viscosity of these formulations hinders manufacturability, injectability, and stability.

Large-scale anaerobic treatment involves a high risk of antibiotic pollution in anaerobically digested (AD) biosolids, which hinders the efficient utilization of farmland AD biosolids. Herein, a process for the in situ removal of antibiotics from AD biosolids using ethylenediaminetetraacetic acid disodium salt dihydrate as the release agent synergized with sodium persulfate oxidation is reported. The developed process was used to remove antibiotics from actual AD biosolids.

High-performance hydrogel biomaterials hold considerable promise for advanced wound care. However, the suboptimal mechanical properties of conventional hydrogel materials limit their practical application. In this study, Hyaluronic acid sodium salt (HA), xanthan gum (XG), and N-acryloyl-glycinamide (NAGA) hydrogels with porous structures were successfully fabricated using in-situ extrusion 3D printing technology, and a functionalization strategy involving tea polyphenol (TP) immersion was proposed to enhance material properties through additional hydrogen bonding.
