Preparation and evaluation of oral insulin nanocapsule delivery systems.

Insulin therapy is essential for regulating blood sugar levels. Conventional subcutaneous injection is prone to psychological stress, local tissue damage and severe blood glucose fluctuations, and thus the development of oral insulin technology has become an alternative therapy. However, oral insulin faces challenges such as difficult absorption, poor adhesion, low bioavailability, and short duration of action, due to the large molecular weight, low permeability, and easily degradable by enzymes and gastric acids.

Effects of carbon nanotube and alumina doping on the properties of para-aramids: A DFT and molecular dynamics study.

Because of its superior mechanical and electrical insulation qualities, paramamid insulating paper is frequently used in the electrical industry. However, a significant barrier preventing it from taking a more prominent role is its low heat conductivity. This research modifies aramid by doping it with carbon nanotubes and alumina to balance its insulating qualities and increase its thermal conductivity.

A Study on the 3D Reconstruction Strategy of a Sheep Body Based on a Kinect v2 Depth Camera Array.

Non-contact measurement based on the 3D reconstruction of sheep bodies can alleviate the stress response in sheep during manual measurement of body dimensions. However, data collection is easily affected by environmental factors and noise, which is not conducive to practical production needs. To address this issue, this study proposes a non-contact data acquisition system and a 3D point cloud reconstruction method for sheep bodies.

Curcumin and Baicalin Co-Loaded Nanoliposomes for Synergistic Treatment of Non-Small Cell Lung Cancer.

Currently, the treatment of patients with advanced non-small cell lung cancer (NSCLC) mainly relies on traditional chemotherapeutic drugs; however, most of them have limited therapeutic effects and high toxicity. Some natural products with good therapeutic efficacy and low toxicity and side effects are limited in clinical application due to their low solubility and bioavailability. In this study, a nanoliposome drug-carrying system (Lip-Cur/Ba) was developed for the co-delivery of curcumin (Cur) and baicalin (Ba) using the thin-film hydration method.

INF2-mediated actin polymerization at ER-organelle contacts regulates organelle size and movement.

Proper regulation of organelle dynamics and inter-organelle contacts is critical for cellular health and function. Both the endoplasmic reticulum (ER) and actin cytoskeleton are known to regulate organelle dynamics, but how, when, and where these two subcellular components are coordinated to control organelle dynamics remains unclear. Here, we show that ER-associated actin consistently marks mitochondrial, endosomal, and lysosomal fission sites.

The Value of Neutrophil-to-Lymphocyte Ratio in Predicting Mortality After Transjugular Intrahepatic Portosystemic Shunt Placement.

Background And Aims: The objective of this study was to investigate the effect of neutrophil-to-lymphocyte ratio (NLR) on the survival of cirrhotic patients with esophagogastric variceal bleeding (EGVB) treated with transjugular intrahepatic portosystemic shunt (TIPS).

Methods: A total of 293 patients treated with TIPS were included. The receiver operator characteristic curve (ROC) was used to calculate the optimal cut-off values of parameters such as NLR.

INF2-mediated actin polymerization at ER-organelle contacts regulates organelle size and movement.

Proper regulation of organelle dynamics is critical for cellular function, but the mechanisms coordinating multiple organelles remain poorly understood. Here we show that actin polymerization mediated by the endoplasmic reticulum (ER)-anchored formin INF2 acts as a master regulator of organelle morphology and movement. Using high-resolution imaging, we demonstrate that INF2-polymerized actin filaments assemble at ER contact sites on mitochondria, endosomes, and lysosomes just prior to their fission.

An integrated magnetic separation enzyme-linked colorimetric sensing platform for field detection of Escherichia coli O157: H7 in food.

An intelligent colorimetric sensing platform integrated with in situ immunomagnetic separation function was developed for ultrasensitive detection of Escherichia coli O157: H7 (E. coli O157: H7) in food. Captured antibody modified magnetic nanoparticles (cMNPs) and detection antibody/horseradish peroxidase (HRP) co-functionalized AuNPs (dHAuNPs) were firstly synthesized for targeted enrichment and colorimetric assay of E.

In-depth discovery and taste presentation mechanism studies on umami peptides derived from fermented sea bass based on peptidomics and machine learning.

Umami peptides originating from fermented sea bass impart a distinctive flavor to food. Nevertheless, large-scale and rapid screening for umami peptides using conventional techniques is challenging because of problems such as prolonged duration and complicated operation. Therefore, we aimed to screen fermented sea bass using peptidomics and machine learning approaches.

Nix interacts with WIPI2 to induce mitophagy.

Nix is a membrane-anchored outer mitochondrial protein that induces mitophagy. While Nix has an LC3-interacting (LIR) motif that binds to ATG8 proteins, it also contains a minimal essential region (MER) that induces mitophagy through an unknown mechanism. We used chemically induced dimerization (CID) to probe the mechanism of Nix-mediated mitophagy and found that both the LIR and MER are required for robust mitophagy.

Two mutations at KRT74 and EDAR synergistically drive the fine-wool production in Chinese sheep.

Introduction: Fine-wool sheep are the most common breed used by the wool industry worldwide. Fine-wool sheep have over a three-fold higher follicle density and a 50% smaller fiber diameter than coarse-wool sheep.

Objectives: This study aims to clarify the underlying genetic basis for the denser and finer wool phenotype in fine-wool breeds.

Effect of Controlling Light on Cashmere Growth and Harmful Gas Parameters in Shanbei White Cashmere Goats.

The quality and yield of cashmere closely affect the economic benefits of cashmere goat farming. Studies have shown that controlling light can have an important impact on cashmere but can also affect the concentration of harmful gases. In order to explore the impact of a short photoperiod on the growth of cashmere and harmful gases in goat houses, 130 female (non-pregnant) Shanbei white cashmere goats, aged 4-5 years with similar body weights, were randomly divided into a control group and a treatment group, with 65 goats in each group.

TNIP1 inhibits selective autophagy via bipartite interaction with LC3/GABARAP and TAX1BP1.

Mitophagy is a form of selective autophagy that disposes of superfluous and potentially damage-inducing organelles in a tightly controlled manner. While the machinery involved in mitophagy induction is well known, the regulation of the components is less clear. Here, we demonstrate that TNIP1 knockout in HeLa cells accelerates mitophagy rates and that ectopic TNIP1 negatively regulates the rate of mitophagy.

Nano Functional Food: Opportunities, Development, and Future Perspectives.

A functional food is a kind of food with special physiological effects that can improve health status or reduce illness. However, the active ingredients in functional foods are usually very low due to the instability and easy degradation of some nutrients. Therefore, improving the utilization rate of the effective ingredients in functional food has become the key problem.

Safe and efficient pesticide formulations have attracted great attention for the prevention and control of diseases and pests. In recent years, improving the effectiveness and duration of pesticides through nanotechnology has become a research hotspot in the field of pesticide formulations. Here, we develop a novel hydrophilic lambda-cyhalothrin nanospheres encapsulated with poly(styrene-co-maleic anhydride) (PSMA) via the ultrasonic emulsification-solvent evaporation method, which exhibited better particle size uniformity and dispersion in comparison with the traditional method.

Mitochondria and peroxisomes are NIXed for clearance.

A recent report shows that the iron chelator DFP induces both mitophagy and pexophagy in a BNIP3/NIX-dependent manner. Previously known as a mitophagy receptor, NIX was also independently localized to peroxisomes to promote pexophagy in several physiological conditions, illustrating the significance of this novel function.

Nano-EMB-SP improves the solubility, foliar affinity, photostability and bioactivity of emamectin benzoate.

Background: Emamectin benzoate (EMB), a frequently used biopesticide, is poorly soluble in water, making it difficult to wet the leaf surface, is prone to degrade in sunlight and readily loses its bioactivity. Traditional methods such as organic solvent application, pH adjustment and addition of photoprotectants either increase the economic and environmental costs or barely achieve the desired goal. We hypothesized that nanotechnology could improve the solubility, foliar affinity, photostability and bioactivity of EMB.
