Platelet-rich fibrin promotes mesothelial cell proliferation and peritoneal repair by up-regulating calretinin to prevent postoperative intestinal adhesion.

As the most common postoperative complication, intestinal adhesions can cause intestinal obstruction, female infertility, and even endanger life. The currently developed materials for preventing intestinal adhesions mainly focus on physical barriers and reducing inflammatory reactions, while neglecting the importance of effectively promoting rapid repair of the peritoneum. We previously found that platelet-rich fibrin (PRF) can prevent postoperative intestinal adhesions.

Editing Benzotrithiophene-Based Covalent Organic Frameworks for Developing New Sonosensitizers.

Recent insights into covalent organic frameworks (COFs) provide an opportunity for developing new sonosensitizers with the advantages of both small molecules and inorganic nanoagents. Herein, we synthesize two benzotrithiophene-based imine-linked COFs (BTT-DPh-COF and BTT-DPy-COF) through density-functional-theory-guided structure editing. The tailored donor-acceptor (D-A) structures optimize the band position of the COFs and endow them with good intrinsic sonodynamic activity, which can efficiently kill cancer cells, showing excellent sonodynamic therapeutic effect.

Characteristics of wetting behavior under unloading in natural granite residual soil.

Excavation of foundation pits induces stress release in the soil, leading to deformation driven by the redistribution of internal stresses and particle adjustment. Rainfall infiltration further increases soil water content, weakening particle bonding through the dissolution of cementing agents, and inducing additional wetting deformation. However, there has only been limited experimental research examining the deformation behavior of soil under the coupled effects of unloading and wetting, especially in water-rich excavation conditions, where these factors interact dynamically.

Field-widened Michelson interferometer with an ultra-wide band and ultra-large field for spectral discrimination in high-spectral-resolution lidar.

A novel field-widened Michelson interferometer (FWMI) with an ultra-wide band and ultra-large field is proposed to act as a spectral discriminator in shipborne oceanic high-spectral-resolution lidar (HSRL). By matching the primary spherical and chromatic aberration, a half field of view (FOV) over 10° throughout a spectral band from visible to near infrared (VIS-NIR) is achieved, which is about three times that of the classic single-wavelength FWMI and 50 times that of the widely used Fabry-Perot interferometer. Fabrication and assembly tolerances are analyzed, demonstrating that the tilt tolerance can be improved by four times as well combined with a pre-focusing system.

Analyzing the interactions between 2-ethylhexyl 4-methoxycinnamate and bovine serum albumin under coexistence and encapsulation of β-cyclodextrin.

2-ethylhexyl 4-methoxycinnamate (EHMC), a UV filter commonly used in sunscreen products, is also an emerging environmental pollutant that interferes with the structure and function of bovine serum albumin (BSA). A study was conducted on the interaction between EHMC and BSA when they coexist and are encapsulated within β-cyclodextrin (β-CD). Multiple spectra demonstrate, both qualitatively and quantitatively, that β-CD coexistence and encapsulation weaken the interaction between EHMC and BSA, resulting in a more difficult binding process between the two and inhibiting EHMC-induced conformational changes in BSA.

Gene therapy in polycystic kidney disease: A promising future.

Polycystic kidney disease (PKD) is a genetic disorder marked by numerous cysts in the kidneys, progressively impairing renal function. It is classified into autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD), with ADPKD being more common. Current treatments mainly focus on symptom relief and slowing disease progression, without offering a cure.

Diagnosis of liver hemangioma using magnetic resonance diffusion-derived vessel density (DDVD) pixelwise map: a preliminary descriptive study.

Background: Liver hemangiomas (HGs) are characterized by cavernous venous spaces delineated by a lining of vascular endothelial cells and interspersed with connective tissue septa. Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

Clinical application of standardization right thoracic incision for thoracoscopic thymic tumor resection.

Background: With the continuous development of minimally invasive thoracic surgery, thoracoscopic thymectomy has become a routine operation. This method, now widely recognized, better protects lung function, reduces intraoperative blood loss and pain, and shortens postoperative hospital stay. We now introduce a standardized right thoracic incision for thoracoscopic thymic tumor resection, which has achieved favorable clinical outcomes.

Skin-interfaced microfluidic biosensors for colorimetric measurements of the concentrations of ketones in sweat.

Ketones, such as beta-hydroxybutyrate (BHB), are important metabolites that can be used to monitor for conditions such as diabetic ketoacidosis (DKA) and ketosis. Compared to conventional approaches that rely on samples of urine or blood evaluated using laboratory techniques, processes for monitoring of ketones in sweat using on-body sensors offer significant advantages. Here, we report a class of soft, skin-interfaced microfluidic devices that can quantify the concentrations of BHB in sweat based on simple and low-cost colorimetric schemes.

Imaging-based surrogate classification for risk stratification of hepatocellular carcinoma with microvascular invasion to adjuvant hepatic arterial infusion chemotherapy: a multicenter retrospective study.

Background: Patients with microvascular invasion (MVI)-positive hepatocellular carcinoma (HCC) have shown promising results with adjuvant hepatic arterial infusion chemotherapy (HAIC) with FOLFOX after curative resection. The authors aim to develop an imaging-derived biomarker to depict MVI-positive HCC patients more precisely and promote individualized treatment strategies of adjuvant HAIC.

Materials And Methods: Patients with MVI-positive HCC were identified from five academic centers and utilized for model development ( n =470).

Synthesis of a catalytic nanomaterial from polypyrrole and a pro-apoptotic peptide to target mitochondria for multimodal cancer therapy.

Development of biocompatible nanomaterials with mitochondria-targeting and multimodal therapeutic activities is important for cancer treatment. Herein, we designed and synthesized a multifunctional pyrrole-based nanomaterial with photothermal effects and mitochondria-targeting properties from polypyrrole and the pro-apoptotic peptide KLA. Different from traditional strategies for the preparation of PPy nanoparticles, we innovatively used the KLA peptide as the template and CuCl as the catalyst to trigger the oxidative polymerization of pyrrole for PPy-KLA-Cu nanoparticle formation.

Fabrication of Nanocatalytic Medicine from Self-Assembling Peptides Containing an ATCUN-Like Copper-Binding Motif for Anticancer Therapy.

Development of nanomaterials with multiple enzymatic activities via a facile approach receives growing interests in recent years. Although peptide self-assembling provides an effective approach for the construction of biomimetic materials in recent years, fabrication of artificial enzymes from self-assembling peptides with multiple catalytic activities for anticancer therapy is still a challenge. Here, we report a simple method to prepare nanocatalysts with multienzyme-like activities from self-assembling peptides containing ATCUN copper-binding motifs.
