Targeting the innate immune response is a critical factor in vaccine success. There are numerous serotypes of Salmonella, and cross-reactivity among different serotypes or even strains within the same serotype is limited. This makes it difficult for vaccines to provide broad protection, posing a challenge to effective prevention and control.

() is a highly detrimental avian pathogen that has resulted in substantial economic losses within the global poultry industry. The existing vaccines, presently in use, fail to offer comprehensive protection. The objective of this study was to create recombinant attenuated vaccine (RASV) strains, namely rSC0130(pS-rRS01790), rSC0130(pS-rBMP), rSC0130(pS-rGrpE), rSC0130(pS-rRS00900), and rSC0130(pS-rRS00275), expressing RS01790, BMP, GrpE, RS00900, and RS00275 proteins, and verify their protective effects.

The run-and-tumble behavior is a simple yet powerful mechanism that enables microorganisms to efficiently navigate and adapt to their environment. These organisms run and tumble alternately, with transition rates modulated by intracellular chemical concentration. We introduce a neural network-based model capable of identifying the governing equations underlying run-and-tumble dynamics.

Sodium-organic batteries (SOBs) are widely recognized as a rising star in large-scale energy storage technology because of their abundant resources, high energy density, and environmental friendliness. However, the poor cyclability and rate performance due to high solubility and poor conductivity with organic electrode materials limit their practical applications. Here, we constructed a new crystalline polymer, poly(tetraaminobenzoquione) (PTABQ), featuring a layered structure with a conjugated backbone and intermolecular hydrogen bonds.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) has recently gained recognition as a rare and fatal disease. Tafamidis, a first-in-class transthyretin stabilizer, has emerged as a promising agent for attenuating disease progression. Nevertheless, how tafamidis alters clinical and imaging parameters remains unclear.

Background: To evaluate the correlation between atrial fibrillation (AF) burden and two-dimensional LA (left atrium) longitudinal reservoir strain (LARS) to explore the potential clinical utility of this novel parameter in patients with AF.

Methods: This cross-sectional study was conducted at the cardiac electrophysiology clinic of a tertiary centre by consecutively enrolling patients with non-valvular AF. The AF burden was evaluated using 14-day patch-based electrocardiography and defined as the percentage of time spent in AF during a 14-day monitoring period.

The transformation of bulk transition-metal dichalcogenide (TMD) particles into ultrathin nanosheets with both an acceptable yield and preserved crystalline integrity presents a substantial challenge in electrochemical exfoliation. This challenge arises from the continuous potential stress that the materials experience in traditional exfoliation setups. Herein, we propose a new fluidized electrochemical exfoliation (FEE) method to efficiently transform TMD powders into high-quality, few-layered TMD nanosheets in the aqueous phase.

Objective: Tafamidis has shown potential in slowing disease progression in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). This study aimed to evaluate serial changes on [Tc]Tc-pyrophosphate (PYP) scintigraphy during tafamidis treatment for hereditary ATTR-CM.

Methods: We retrospectively analyzed a prospectively collected cohort of Ala97Ser (A97S) hereditary ATTR-CM patients treated with tafamidis (61 mg/day) and a control group comprising A97S hereditary ATTR-CM patients who had not received disease-modifying medications.

Nanovaccines have significantly contributed in the prevention and treatment of diseases. However, most of these technologies rely on chemical or hybrid semibiological synthesis methods, which limit the manufacturing performance advantages and improved inoculation outcomes compared with traditional vaccines. Herein, a universal and purely biological nanovaccine system is reported.

Article Synopsis
  • - Researchers explored how changing the coordination environment of single-atom catalysts (SACs) affects their efficiency in electrocatalytic CO reduction, specifically using single-atom Ag on N-doped carbon with different nitrogen arrangements.
  • - By adjusting the proportions of pyrrolic and pyridine nitrogen, they found that a catalyst with 40% pyrrolic N yielded a high Faradaic efficiency (FE) of 69.7% for CO formation, while a catalyst with 70.5% pyridine N achieved a stable FE of 40% for CHOH production.
  • - The study provides insights into the roles of different nitrogen types, suggesting that pyrrolic N enhances CO conversion, while pyridine N

The H9N2 inactivated avian influenza vaccine cannot induce cellular and mucosal immune responses, while the attenuated Salmonella vector as an intracellular bacterium can induce dominant cellular and mucosal immune responses. However, it provides low protection against the virus when delivering viral antigens and needs further optimization. Chicken C-C motif chemokine ligand 5 (chCCL5) is an important CC chemokine associated with immune cell chemotaxis, migration, and viral infection.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta, leading to motor and non-motor symptoms. Emerging evidence suggests that inflammation plays a crucial role in the pathogenesis of PD, with the NLRP3 inflammasome implicated as a key mediator. Nfon-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), have recently garnered attention for their regulatory roles in various biological processes, including inflammation.
