Initiated chemical vapor deposition (iCVD) has emerged as a versatile technique for developing functional nanocoatings that address critical food and agricultural challenges. This review highlights the unique capacities of iCVD nanocoatings, which enable precise engineering of surface properties, such as targeted cellular and molecular interactions, antimicrobial activity, and fouling resistance. In addition, the solvent-free nature of iCVD is particularly advantageous for coating sensitive materials and complex geometries commonly used across food and agriculture applications.

Initiated chemical vapor deposition (iCVD) is a versatile technique that enables the direct growth of nanostructures and surface modification of such structures. Unlike traditional CVD methods, iCVD operates under mild conditions, allowing for damage-free processing of delicate substrates. It can produce highly uniform polymer layers, with thicknesses ranging from over 15 μm to sub-10 nm, conformally coating intricate geometries.

Galectins are a member of the β-galactoside binding protein family, which play a pivotal role in the immune defense of vertebrates as a pattern recognition receptor and occupy an important position in the innate immune system of invertebrates. The study of galectins in aquatic organisms has only recently emerged. Galectins in aquatic animals exhibit agglutination activity toward bacteria, inhibit bacterial growth, and enhance phagocytosis of immune cells.

Article Synopsis
  • - This study examines how AMPK signaling affects mitochondrial functions and mitophagy in human trophoblast cells, particularly using next generation RNA-seq to identify relevant genes and pathways.
  • - It found that knocking down specific AMPK genes (PRKAA1/2) resulted in lower ATP production, especially in mitochondria, and identified a total of 1,092 differentially expressed genes.
  • - Analysis revealed clusters of mitochondria-related genes that may play a role in the altered mitochondrial functions due to reduced AMPK signaling, providing insights into the importance of AMPK in cell energy management.

Infiltration of monocyte-derived macrophages plays a crucial role in cardiac remodeling and dysfunction. The serum and glucocorticoid-inducible protein kinase 3 (SGK3) is a downstream factor of PI3K signaling, regulating various biological processes via an AKT-independent signaling pathway. SGK3 has been implicated in cardiac remodeling.

Biomaterial-associated infections caused by bacteria pose a great threat to human health, and therefore, various antibacterial coatings have been developed to control bacterial infections. Povidone iodine (PVP-I) is a broad-spectrum antimicrobial agent without drug resistance to most pathogenic microorganisms and has been widely used in the clinic. However, its applications in the field of coatings are limited due to its strong water solubility.

Background: Syringic acid (SA) is a high-value natural compound with diverse biological activities and wide applications, commonly found in fruits, vegetables, and herbs. SA is primarily produced through chemical synthesis, nonetheless, these chemical methods have many drawbacks, such as considerable equipment requirements, harsh reaction conditions, expensive catalysts, and numerous by-products. Therefore, in this study, a novel biotransformation route for SA production was designed and developed by using engineered whole cells.

Parasitic diseases including malaria, leishmaniasis, and trypanosomiasis have received significant attention due to their severe health implications, especially in developing countries. Marine natural products from a vast and diverse range of marine organisms such as sponges, corals, molluscs, and algae have been found to produce unique bioactive compounds that exhibit promising potent properties, including antiparasitic, anti-Plasmodial, anti-Leishmanial, and anti-Trypanosomal activities, providing hope for the development of effective treatments. Furthermore, various techniques and methodologies have been used to investigate the mechanisms of these antiparasitic compounds.

Background: Knee stability can be safely and reliably restored using medial patellofemoral ligament (MPFL) reconstruction, which is widely recognized in patients with recurrent lateral patellar instability. However, the literature regarding its influence on static balance control is limited. Thus, this study aimed to assess the impact of MPFL reconstruction on balance control and determine its functional significance.

The differential count of white blood cells (WBCs) can effectively provide disease information for patients. Existing stained microscopic WBC classification usually requires complex sample-preparation steps, and is easily affected by external conditions such as illumination. In contrast, the inconspicuous nuclei of stain-free WBCs also bring great challenges to WBC classification.

Benzylamine is a valuable intermediate in the synthesis of organic compounds such as curing agents and antifungal drugs. To improve the efficiency of benzylamine biosynthesis, we identified the enzymes involved in the multi-enzyme cascade, regulated the expression strength by using RBS engineering in Escherichia coli, and established a regeneration-recycling system for alanine. This is a cosubstrate, coupled to cascade reactions, which resulted in E.

Background: Intrauterine growth retardation (IUGR) is one of the major constraints in animal production. Our previous study showed that piglets with IUGR are associated with abnormal bile acid (BA) metabolism. This study explored whether dietary BA supplementation could improve growth performance and colonic development, function, microbiota, and metabolites in the normal birth weight (NBW) and IUGR piglets.

Maternal obesity is associated with a variety of obstetrical outcomes including stillbirth, preeclampsia, and gestational diabetes, and increases the risk of fetuses for congenital heart defects. Obesity during pregnancy represents a major contribution to metabolic dysregulation, which not only plays a key role in the pathogenesis of adverse outcome but also can potently induce endoplasmic reticulum (ER) stress. However, the mechanism associating such an obesogenic metabolic environment and adverse pregnancy outcomes has remained poorly understood.

, the causative agent of alveolar echinococcosis (AE), severely threats human health and livestock farming. The first line of chemotherapeutic drug for AE is albendazole, which limits rapid extension of metacestodes, but is rarely curative for AE, with severe side effects in long-term use, thus development of new anti-echinococcal drugs is mandated. Pseudolaric acid B (PAB) has long been used to treat fungal-infected dermatosis, and exerted anti-tumor, -fertility, -angiogenesis, -tubulin and antiparasitic activity.

Article Synopsis
  • Glioma is a tough brain cancer that doesn't have a good outlook for patients, but berberine (BBR) is a natural compound that can fight these cancer cells.
  • Researchers found that berberine works by blocking a bad protein and causing damage to the cancer cells' energy centers, and it also affects collagen, which is important for cell movement.
  • The study showed that berberine stops glioma cells from spreading by targeting a specific protein (COL11A1), suggesting it could be a helpful treatment for this kind of cancer in the future.

Introduction: Accumulating evidence suggests that mitochondrial structural and functional defects are present in human placentas affected by pregnancy related disorders, but mitophagy pathways in human trophoblast cells/placental tissues have not been investigated.

Methods: In this study, we investigated three major mitophagy pathways mediated by PRKN, FUNDC1, and BNIP3/BNIP3L in response to AMPK activation by AICAR and knockdown of (AKD) in human trophoblast cell line BeWo and the effect of AKD on mitochondrial membrane potential and ATP production.

Results: Autophagy flux assay demonstrated that AMPK signaling activation stimulates autophagy, evidenced increased LC3II and SQSTM1 protein abundance in the whole cell lysates and mitochondrial fractions, and mitophagy flux assay demonstrated that the activation of AMPK signaling stimulates mitophagy via PRKN and FUNDC1 mediated but not BNIP3/BNIP3L mediated pathways.
