Massively parallel barcode sequencing revealed the interchangeability of capsule transporters in .

Multidrug/oligosaccharidyl-lipid/polysaccharide (MOP) family transporters are essential in glycan synthesis, flipping lipid-linked precursors across cell membranes. Yet, how they select their substrates remains enigmatic. Here, we investigate the substrate specificity of the MOP transporters in the capsular polysaccharide (CPS) synthesis pathway in .

Removal of dissolved organic carbon in the West Pacific hadal zones.

The deep oceans are environments of complex carbon dynamics that have the potential to significantly impact the global carbon cycle. However, the role of hadal zones, particularly hadal trenches (water depth > 6 km), in the oceanic dissolved organic carbon (DOC) cycle is not thoroughly investigated. Here we report distinct DOC signatures in the Japan Trench bottom water.

Migration and plugging laws of plugging-selection balls in fine profile control process of layered waterflooding wells.

The ball-pitching plugging-selection profile control technology represents an effective and low-cost means of adjusting the profile of waterflooding well. The technology primarily utilizes polymer balls to plug the perforations, thereby achieving the effect of fine profile control. This paper aims to elucidate the migration and plugging laws of plugging-selection balls in wellbore and perforation plugging processes.

Application of nanomedicines in tumor immunotherapy.

Tumor immunotherapy has emerged as a formidable strategy, demonstrating substantial achievements in the field of cancer treatment. Despite its remarkable success, intrinsic limitations such as insufficient targeting capabilities, side effects, and resistance to immunotherapy hinder its efficacy. To address these challenges, the utilization of nanomedicines in tumor immunotherapy has been broadly explored, capitalizing on their advantages of targeting delivery capability, loading capacity, modifiability, and biocompatibility.

Single-Atom Mo Supported by TiO for Photocatalytic Nitrogen Fixation.

The challenge of achieving efficient photocatalysts for the fixation of ambient nitrogen to ammonia persists. The utilization efficiency of single-metal-atom catalysts leads to an increased number of active sites, while their distinctive geometrical and electronic characteristics contribute to enhancing the intrinsic activity of each individual site. In this study, we present a method using an organic molecule to assist in loading TiO with Mo single atoms for the purpose of photocatalytic nitrogen fixation.

Elastic-plastic fracture analysis of pressure pipelines with axial cracks based on the interaction integral method.

The proposed work aims to demonstrate the significance of the plastic zone at the tip of an axial crack in a pipeline for managing Stress IntensityFactors(SIF). The three-dimensional finite element model of pressure pipeline with axial cracks was built by utilizing the Ramberg-Osgood X80 material model of pipeline. according to Von Mises yield criterion, the size of plastic zone at crack tip was determined, and the fracture parameters were calculated based on interaction integral method, the plastic stress deformation law, determination of elastic-plastic limit load and plastic correction of SIF at crack tip of pressure pipeline with axial crack were discussed.

STING-Activating Polymers Boost Lymphatic Delivery of mRNA Vaccine to Potentiate Cancer Immunotherapy.

The unprecedented success of mRNA vaccines against COVID-19 has inspired scientists to develop mRNA vaccines for cancer immunotherapy. However, using nucleoside modified mRNA as vaccine, though evading innate immune toxicity, diminishes its therapeutic efficacy for cancers. Here, we report a polyvalent stimulator of interferon genes (STING) activating polymer (termed as PD) to bolster the immunogenicity of mRNA vaccine.

Integrative multi-omics analysis reveals a novel subtype of hepatocellular carcinoma with biological and clinical relevance.

Background: Hepatocellular carcinoma (HCC) is a highly heterogeneous tumor, and the development of accurate predictive models for prognosis and drug sensitivity remains challenging.

Methods: We integrated laboratory data and public cohorts to conduct a multi-omics analysis of HCC, which included bulk RNA sequencing, proteomic analysis, single-cell RNA sequencing (scRNA-seq), spatial transcriptomics sequencing (ST-seq), and genome sequencing. We constructed a tumor purity (TP) and tumor microenvironment (TME) prognostic risk model.

Case report: Fecal microbiota transplant for infection in a pregnant patient with acute severe ulcerative colitis.

Ulcerative colitis (UC) is a chronic colonic mucosal inflammation characterized by reduced gut microbial diversity. Patients with UC at pregnancy are prone to suffer from severe disease progression due to the changes of hormone and immune regulation. Fecal microbiota transplant (FMT) is a promising therapy for UC and recurrent infection (CDI).

Design of High-Performance Infrared Nonlinear Optical PAsS with Perfectly Aligned Polar Molecular Cage via a Bipolar-Axis-Symmetry Coupling Strategy.

Strong polar molecular cages have recently emerged as novel functional building units for high-performance infrared nonlinear optical (IR NLO) crystals. However, these highly polar molecular cages often arrange themselves in a way that cancels out their polarity, leading to a more energetically stable state. As a result, most cage crystal formations tend to crystallize in centrosymmetric space groups, which conflicts with the primary requirement for NLO crystals.

Boronic Acid and Phosphoyl Chloride-Mediated Site-Selective Ketalization of Unprotected Saccharides: In Situ Generation of a Proton Catalyst and Multiple Roles of Reagents.

In the chemical synthesis or modification of saccharides, regioselective protection of the many similar OH groups in saccharides is necessary but remains a major challenge. In particular, the regio- and stereoselective conversion of C(1,2)-OH has great synthetic potential in carbohydrate synthesis but has largely remained untapped. Here, an in situ proton-producing system mediated by boronic acid was found and employed for site-selective ketalization of various unprotected saccharides.
