Highly Bioadaptive Scaffolds with Tuned Porous Structure Templated by Xylan Nanocrystal High Internal Phase Pickering Emulsions.

Fabrication of traditional 3D cell culturing scaffolds requires synthetic polymers or additives, posing a risk of poor biocompatibility and low biodegradability. Pickering emulsions stabilized by biobased nanomaterials can be used as templates to produce scaffolds with facile tunable porous structure, excellent cytocompatibility, and biodegradability. In this study, very stable high internal phase Pickering emulsions (HIPPE) with an oil content of 80% were successfully prepared by xylan hydrate nanocrystals (XNC).

Global distribution and genomic characteristics analysis of avian-derived mcr-1-positive Escherichia coli.

The prevalence of avian-derived Escherichia coli (E. coli) carrying mcr-1 poses a significant threat to the development of the poultry industry and public health safety. Despite ongoing in-depth epidemiological research worldwide, a comprehensive macroscopic study based on genomics is still lacking.

Dual function of carboxymethyl cellulose scaffold: A one-stone-two-birds strategy to prepare double-layer hollow ZIF-67 derivates for flame retardant epoxy composites.

Aluminum hypophosphite (AHP) has been used as a flame retardant for a long time. Previous studies about AHP employed in flame retardant materials mostly focus on coating, modification, and complex system. It is valuable to explore simple experimental steps to prepare nano hybrids with AHP and metal-organic frameworks (MOFs).

Synchronous modification of ZIF-67 with cyclomatrix polyphosphazene coating for efficient flame retardancy and mechanical reinforcement of epoxy resin.

Cyclomatrix polyphosphazenes have attracted widespread attention in the field of polymer flame retardancy. Nevertheless, the optimal manifestation of their distinctive structural attributes and flame-retardant properties necessitates a judicious selection of condensation monomers and synergistic templates during the fabrication of polyphosphazene flame retardants. In our previous studies, it was discovered that when ZIF-67 is functionalized with polyphosphazene, the by-product HCl from phosphazene polycondensation causes etching on ZIF-67.

Enhancing char formation of flame retardant epoxy composites: Onigiri-like ZIF-67 modification with carboxymethyl β-cyclodextrin crosslinking.

To enhance char formation of flame retardant epoxy (EP) composites, carboxymethyl β-cyclodextrin (CM-β-CD) is employed as an etchant for or ZIF-67 derivatives. In the early stage, etching plays a dominant role. The mismatch in size between CM-β-CD opening and ZIF-67 pore leads to the stacking of carboxyl cobalt complexes on the shell.

Bioinformatics analysis of CMTM family in pan-cancer and preliminary exploration of CMTM6 in bladder cancer.

Background: The chemokine-like factor (CKLF)-like Marvel transmembrane structural domain (CMTM) family is widely expressed in the tumor and immune systems and is essential in human cancer progression. However, the multi-omic profile of CMTM family genes and their role in tumor patient prognosis and immune microenvironment have not been explored.

Methods: We collected data from 33 cancers and 33 non-cancers and then comprehensively analyzed the basal expression levels of CMTM family genes in normal human tissues as well as abnormal expression in diseases, genomic alterations, diagnostic and prognostic roles, subcellular localization, pathway enrichment, the immune microenvironment, associations with immune checkpoints, and drug sensitivities as well as to predict the immunotherapeutic response of patients to ICIs and targeting of small molecule drugs, the above results were validated by immunohistochemical staining, pathology sections and experiments.

Significantly improve film formability of acetylated xylans by structure optimization and solvent screening.

Acetylated xylans have great potential in fabricating functional film and coating materials, which need a good solubility/dispersibility and film formability in an easily evaporable solvent. However, the changes of film formability with degree of substitution by acetyls (DS) in different solvent systems for xylans have not been extensively studied, which limit the application of acetylated xylans in film materials. In this study, acetylated xylans with DS of 0-2 were prepared and the effects of acetyl groups on solubility/dispersibility, crystallinity and film formability of xylans in water and chloroform solvent systems were investigated.

Cap-assisted endoscopic sclerotherapy is effective for rectal mucosal prolapse associated outlet obstructive constipation.

Background And Study Aims: Outlet obstructive constipation (OOC) is a common type of chronic constipation that is usually caused by internal hemorrhoids (IH) and rectal mucosal prolapse (RMP). Cap-assisted endoscopic sclerotherapy (CAES) was demonstrated to be effective in the treatment of IH and RMP. This study explored the efficacy of CAES in treating OOC associated with IH and RMP.

Transient delayed gastric emptying following laparoscopic Nissen fundoplication for gastroesophageal reflux disease.

Purpose: Although laparoscopic Nissen fundoplication (LNF) is a kind of minimally invasive surgery, some transition time may still be required to allow the fundoplicated stomach to adapt to the new anatomical position. We observed transient delayed gastric emptying (DGE) post-LNF in our preliminary study. This study aimed to investigate the occurrence rate and development of transient DGE post-LNF.

A case report of eosinophilic gastroenteritis misdiagnosed as cholelithiasis.

Eosinophilic gastroenteritis is not only easy to ignore in clinical practice, but also easy to miss in the process of pathological diagnosis. There is a need to consider it in the differential diagnosis of alimentary disease.

The Application of Polysaccharides and Their Derivatives in Pigment, Barrier, and Functional Paper Coatings.

As one of the most abundant natural polymers in nature, polysaccharides have the potential to replace petroleum-based polymers that are difficult to degrade in paper coatings. Polysaccharide molecules have a large number of hydroxyl groups that can bind strongly with paper fibers through hydrogen bonds. Chemical modification can also effectively improve the mechanical, barrier, and hydrophobic properties of polysaccharide-based coating layers and thus can further improve the related properties of coated paper.

Rice Morphogenesis and Chlorophyll Accumulation Is Regulated by the Protein Encoded by and Its Interaction With NAL9.

Rice yield is closely related to plant leaf shape and chlorophyll content. In this study, we isolated and identified a narrow and rolled leaf mutant, temporarily named with darker green leaves. Histological analysis showed that has a reduced number of vascular bundles and undergoes abnormal abaxial sclerenchymatous cell differentiation.

Early responses of silkworm midgut to microsporidium infection--A Digital Gene Expression analysis.

Host-pathogen interactions are complex processes, which have been studied extensively in recent years. In insects, the midgut is a vital organ of digestion and nutrient absorption, and also serves as the first physiological and immune barrier against invading pathogenic microorganisms. Our focus is on Nosema bombycis, which is a pathogen of silkworm pebrine and causes great economic losses to the silk industry.

Detection of Nosema bombycis by FTA cards and loop-mediated isothermal amplification (LAMP).

We successfully established a detection method which exhibited a markedly higher sensitivity than previously developed detection methods for Nosema bombycis by combining glass beads, FTA card, and LAMP. Spores of N. bombycis were first broken by acid-washed glass beads; the DNA was subsequently extracted and purified with the FTA card, and LAMP was performed using primers (LSU296) designed based on the sequence of the LSU rRNA of N.
