Article Synopsis
  • Gastric cancer (GC) is a major health issue due to treatment failures, largely influenced by specific subtypes of cancer-associated fibroblasts (CAFs) that hinder T-cell infiltration and promote immunotherapy resistance.
  • Researchers analyzed a large dataset to identify and characterize 17 fibroblast subsets associated with gastric cancer, revealing nine that don't fit established classifications, which vary in their biological and clinical roles.
  • Notably, cluster 6 showed characteristics linked to poor survival and immunotherapy response, linked to an immunosuppressive environment, and was found to promote cancer cell proliferation through a specific signaling pathway.

Irregular bone defects caused by trauma and bone diseases provide a complex implant environment for surgery. Traditional implants often fail to integrate well with the surrounding bone defect interface, therefore, developing an artificial bone scaffold that can adapt to irregular bone defect boundaries is of significant importance for bone defect repair. This study successfully utilized a shape memory ternary copolymer polylactic acid-trimethylene carbonate-hydroxyacetic acid (PLLA-TMC-GA) and dopamine-modified nano-hydroxyapatite (PHA) composite to construct a temperature-responsive bone repair scaffold (PTG/PHA), thereby enhancing the interface compatibility between the implant and the surrounding environment.

Article Synopsis
  • Plant cell walls are like shields for plants against germs, and there’s a constant battle between them and the bad germs.
  • A special protein from a germ weakens the plant walls, but plants have their own protein that helps protect them.
  • Scientists used AI to create a new version of the plant protein that can specifically fight off the germ’s attacks, making plants stronger against these harmful germs.

Variations in chromosome number are occasionally observed among oomycetes, a group that includes many plant pathogens, but the emergence of such variations and their effects on genome and virulence evolution remain ambiguous. We generated complete telomere-to-telomere genome assemblies for Phytophthora sojae, Globisporangium ultimum, Pythium oligandrum, and G. spinosum.

Infected bone defects are one of the most challenging problems in the treatment of bone defects due to the high antibiotic failure rate and the lack of ideal bone grafts. In this paper, inspired by clinical bone cement filling treatment, α-c phosphate (α-TCP) with self-curing properties is composited with β-tricalcium phosphate (β-TCP) and constructed a bionic cancellous bone scaffolding system α/β-tricalcium phosphate (α/β-TCP) by low-temperature 3D printing, and gelatin is preserved inside the scaffolds as an organic phase, and later loaded with a metal-polyphenol network structure of tea polyphenol-magnesium (TP-Mg) nanoparticles. The scaffolds mimic the structure and components of cancellous bone with high mechanical strength (>100 MPa) based on α-TCP self-curing properties through low-temperature 3D printing.

Osteomyelitis is a devastating disease caused by microbial infection in deep bone tissue. Its high recurrence rate and impaired restoration of bone deficiencies are major challenges in treatment. Microbes have evolved numerous mechanisms to effectively evade host intrinsic and adaptive immune attacks to persistently localize in the host, such as drug-resistant bacteria, biofilms, persister cells, intracellular bacteria, and small colony variants (SCVs).

Article Synopsis
  • * A study in the economically developed Yangtze River Delta of China utilized GIS mapping, PMF modeling, and cadmium isotope fingerprinting to identify sources of contamination, revealing that cadmium (Cd) was the most contaminated element.
  • * Findings indicated that industrial activities, particularly from electroplating and non-ferrous metal smelting, accounted for nearly 50% of soil Cd pollution, highlighting the need for targeted pollution control and remediation efforts.

Article Synopsis
  • Fusion genes from the epidermal growth factor (EGF) receptor family are significant players in cancer development, especially in lung cancer, where gene fusion incidence is 0.19 to 0.27%.
  • Common partners for these fusions are CD74 and SLC3A2, and detection methods include RNA-based next-generation sequencing and pERBB3 immunohistochemistry for quick screening.
  • Currently, there are no approved specific drugs for these fusions, but treatment options like pan-ERBB inhibitors and monoclonal antibodies are being explored, with clinical trials aiming to improve outcomes for patients with solid tumors containing these gene fusions.

Article Synopsis
  • The study aims to create a new six-part classification method for intertrochanteric femur fractures using 3D-CT images and fracture stability analysis to enhance diagnostics for unstable fractures.
  • The research involved a retrospective analysis of 320 patients who underwent surgery, comparing the newly proposed classification to the established AO classification based on fracture stability rates.
  • Results indicated that the two classification methods had similar fracture stability rates, with no significant difference found in their effectiveness for assessing stability.

The endometrium is a unique human tissue with an extraordinary ability to undergo a hormone-regulated cycle encompassing shedding, bleeding, scarless repair, and regeneration throughout the female reproductive cycle. The cyclical repair and regeneration of the endometrium manifest as changes in endometrial epithelialization, glandular regeneration, and vascularization. The mechanisms encompass inflammation, coagulation, and fibrinolytic system balance.

In recent years, hydrogels have been widely used in the biomedical field as materials with excellent bionic structures and biological properties. Among them, the excellent comprehensive properties of natural polymer hydrogels represented by sodium alginate have attracted the great attention of researchers. At the same time, by physically blending sodium alginate with other materials, the problems of poor cell adhesion and mechanical properties of sodium alginate hydrogels were directly improved without chemical modification of sodium alginate.

Human bone is composed of cortical bone and cancellous bone. The interior portion of natural bone is cancellous with a porosity of 50%-90%, but the outer layer is made of dense cortical bone, of which porosity was not higher than 10%. Porous ceramics were expected to be research hotspot in bone tissue engineering by virtue of their similarity to the mineral constituent and physiological structure of human bone.

Rapid formation of innovative, inexpensive, personalized, and quickly reproducible artery bioresorbable stents (BRSs) is significantly important for treating dangerous and sometimes deadly cerebrovascular disorders. It is greatly challenging to give BRSs excellent mechanical properties, biocompatibility, and bioabsorbability. The current BRSs, which are mostly fabricated from poly-l-lactide (PLLA), are usually applied to coronary revascularization but may not be suitable for cerebrovascular revascularization.

Construction of metal selenides with a large specific surface area and a hollow structure is one of the effective methods to improve the electrochemical performance of supercapacitors. However, the nano-material easily agglomerates due to the lack of support, resulting in the loss of electrochemical performance. Herein, we successfully design a three-dimensional graphene (3DG) encapsulation-protected hollow nanoboxes (CoSe-SnSe) composite aerogel (3DG/CoSe-SnSe) via a co-precipitation method coupled with self-assembly route, followed by a high temperature selenidation strategy.
