Aflatoxin B (AFB ) is the predominant mycotoxin that originated toxicity in broilers through oxidative damage, intestinal barrier dysfunction, reduced immune system and dysfunction of microorganisms and enzymes in target organs. The intestine is the first AFB target organ destroyed after the bird's body is induced. This review summarises the current knowledge of the negative results of AFB -induced intestinal damage on broiler production. It was conducted in accordance with the relevant studies in the cited literatures being retrieved from PubMed, Google Scholar, Science Direct and Web of Science. First, AFB can change the intestinal barrier function by destroying the intestinal architecture, tissue and cell integrity of the gut epithelium. Second, AFB can damage the immune barrier function of the gastrointestinal mucosa. Third, the microbiota of birds interacts closely with the ingested aflatoxin. Finally, because broilers are tremendously sensitive to AFB contamination, the poisonous and noxious effects of this mycotoxin in the broiler industry cause millions of dollars in losses every year. This review briefly discussed that the AFB , which affects the intestines of broiler chickens, was reduced the immune apparatus, antioxidant protection system, gastric system, and broiler production status and its impact on human health. Therefore, this review will improve our perception of the important intestine in a bird's health and the adverse effect of AFB .

The mycotoxin, aflatoxin B (AFB), is a potent mutagen that contaminates agricultural food supplies. After ingestion, AFB is oxidized into a reactive electrophile that alkylates DNA, forming bulky lesions such as the genotoxic formamidopyrimidine lesion, AFB-Fapy dG. This lesion is mainly repaired by nucleotide excision repair (NER) in bacteria; however, in humans the picture is less clear.

This study addresses a critical limitation in direct bonded copper (DBC) materials used in power electronics by introducing a copper-zirconium (Cu/Zr) alloy interposing layer at the copper-ceramic interface. This novel design aims to mitigate mechanical stress induced by mismatched material properties, such as the coefficient of thermal expansion (CTE) and elastic modulus, during thermal cycling. The key findings of this study are (1) thermal fatigue improvement: Test samples with the Cu/Zr interface layer (Cu-Cu/Zr-AlN) three times enhanced thermal fatigue resistance, surviving 30 thermal cycles from -55 to 300 °C before delamination, while standard DBC substrates without the Cu/Zr layer failed after just 10 cycles, indicating a performance improvement with the Cu/Zr alloy, (2) durability projections: Based on the Coffin-Manson model, if the upper temperature is capped at 150 °C, the Cu-Cu/Zr-AlN substrates are projected to survive approximately 1372 cycles, underscoring their potential for long-term reliability, and (3) stress mitigation: The Cu/Zr alloy layer bridges the CTE disparity between copper and ceramic, reducing mechanical stress and improving structural integrity across a broad temperature range (-55 to 300 °C).

Aluminum nanoparticles (Al NPs) were synthesized via catalyzed thermal reduction of an aluminum precursor in the presence of a capping ligand. A systematic study was conducted to examine the effect of dilution on nanoparticle synthesis by varying the volume of anhydrous toluene across four dilution factors while maintaining constant molar quantities of the aluminum precursor, catalyst, and ligand. This methodology is relevant for scale-up processes, where more dilute conditions can mitigate nanoparticle reactivity and enhance safety.

A dual-mode aptasensor was engineered for aflatoxin B (AFB) detection by functional integration of peroxidase-mimetic Au@CeO core-shell nanostructures with emissive carbon dots (CDs). The Au@CeO nanocomposite, synthesized via spontaneous redox reaction, exhibited enhanced peroxidase-like activity due to abundant Ce/oxygen vacancies facilitating hydroxyl radical generation. The aptasensor utilizes a competitive binding mechanism, where AFB competed with immobilized Au@CeO-CDs-Apt1 probes for binding sites, resulting in inversely proportional colorimetric and fluorescent signals.

Background: The urinary lipoarabinomannan (LAM) assay has emerged as a promising tool for tuberculosis (TB) diagnosis and treatment monitoring. This study aimed to evaluate the diagnostic and monitoring performance of LAM compared to Acid-fast bacilli (AFB), Mycobacteria Growth Indicator Tube (MGIT), and GeneXpert, and to establish its clinical utility in a stratified TB population.
Methods: A prospective cohort study included TB patients stratified by AFB/MGIT status into three groups.
