Preoperative assessment of tertiary lymphoid structures in stage I lung adenocarcinoma using CT radiomics: a multicenter retrospective cohort study.

Objective: To develop a multimodal predictive model, Radiomics Integrated TLSs System (RAITS), based on preoperative CT radiomic features for the identification of TLSs in stage I lung adenocarcinoma patients and to evaluate its potential in prognosis stratification and guiding personalized treatment.

Methods: The most recent preoperative chest CT thin-slice scans and postoperative hematoxylin and eosin-stained pathology sections of patients diagnosed with stage I LUAD were retrospectively collected. Tumor segmentation was achieved using an automatic virtual adversarial training segmentation algorithm based on a three-dimensional U-shape convolutional neural network (3D U-Net).

Phenotypic vs. Genetic Mismatch of BMI and Type 2 Diabetes: Evidence from Two Perspective Cohort Studies.

Little is known about the population-based mismatch between phenotypic and genetic BMI (BMI-PGM) and its association with type 2 diabetes. We therefore used data from the China Kadoorie Biobank and UK Biobank and calculated BMI-PGM for each participant as the difference between the percentile for adjusted BMI at baseline and the percentile for adjusted polygenic risk score for BMI. Participants were categorized into discordantly low (BMI-PGM< the 1st quartile), concordant (the 1st quartile ≤BMI-PGM View Article and Find Full Text PDF

Carboxymethyl chitosan: Synthesis, functional properties, and applications in sustainable food packaging material.

Global environmental concerns about non-degradable packaging materials are increasing. Carboxymethyl chitosan (CMCS), a polysaccharide widely used in the food industry, has gained attention in the field of food packaging. Due to its biodegradability, film-forming ability, and biocompatibility, CMCS has emerged as a sustainable option for degradable and functional food packaging materials, offering solutions to plastic pollution and food waste issues.

Mechanisms of polygalasaponin F against brain ischemia-reperfusion injury by targeting NKCC1.

Stroke is a serious threat to human health and current clinical therapies remain unsatisfactory. Elevated expression of Na-K-2Cl cotransporter 1 (NKCC1) following stroke can disrupt the blood-brain barrier (BBB) and result in brain edema, indicating that NKCC1 may be a potential therapeutic target for improving stroke outcomes. Polygalasaponin F (PGSF) is a triterpenoid saponin isolated from Polygala japonica Houtt, which has showed neuroprotective effects in previous studies.

CAVIN2 attenuates ventilator-induced lung injury in rats by MAPK/ERK1/2 signaling pathway.

Background: Mechanical ventilation is an important treatment in medical treatment, but it may cause or aggravate lung injury, which is called ventilator-induced lung injury (VILI). Studies have shown that CAVIN2 plays an important role in regulating inflammatory responses and cell death. However, its functional mechanism in VILI remains unclear.

Risk prediction of ischemic heart disease using plasma proteomics, conventional risk factors and polygenic scores in Chinese and European adults.

Plasma proteomics could enhance risk prediction for multiple diseases beyond conventional risk factors or polygenic scores (PS). To assess utility of proteomics for risk prediction of ischemic heart disease (IHD) compared with conventional risk factors and PS in Chinese and European populations. A nested case-cohort study measured plasma levels of 2923 proteins using Olink Explore panel in ~ 4000 Chinese adults (1976 incident IHD cases and 2001 sub-cohort controls).

Objective: To study the influences of LncRNA H19 (H19) on malignant liver tumor cells and elucidate the underlying molecular mechanisms.

Methods: H19 expression in liver tumor tissues, matched normal liver tissues, human liver malignant tumor cell lines and the human hepatocyte line LO2 was assessed via quantitative RT-PCR. Cell viability analysis and Matrigel invasion analysis were performed to evaluate the effects of H19 on cell proliferation and invasion.

Trends of genetic contributions on epigenetic clocks and related methylation sites with aging: A population-based adult twin study.

Several crucial acceleration periods exist during aging process. Epigenetic clocks, serving as indicators of aging, are influenced by genetic factors. Investigating how the genetic contributions on these clocks change with age may provide novel insights into the aging process.

Sorafenib-induced macrophage extracellular traps via ARHGDIG/IL4/PADI4 axis confer drug resistance through inhibiting ferroptosis in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is one of the most common as well as leading causes of mortality worldwide, and sorafenib is the first-line treatment in HCC patients. Unfortunately, drug resistance to sorafenib often develops. However, the underlying mechanism remains unclear.

The Frequency of Meal-Replacement Products Drinking and All-Cause, CVD, and Cancer Mortality.

Objectives: Our study aimed to assess the associations between meal-replacement (MR) drinking and risks of all-cause, cardiovascular and cerebrovascular disease (CVD), and cancer mortality.

Methods: The study was based on 6770 adults aged 20 years or older from the National Health and Nutrition Examination (NHANES) 2003-2006 with linked mortality data from the National Death Index for linked mortality records (until 31 December 2019). Respondents were categorized into four groups according to the frequency of MR drinking: ≤1 time per month (seldom), 2-3 times per month (monthly), 1-6 times per week (weekly), and ≥1 time per day (daily).

A Novel Delivery Approach of Clinical Inner Ear Gene Therapy.

Background: To create and develop a delivery approach for clinical inner ear gene therapy, we conducted a study of trans-round window membrane (RWM) microinjection using a pipetting microneedle via transcanal endoscopic ear surgery (TEES).

Methods: The implementation of the trans-RWM microinjection surgery involved seven cadaveric specimens, and the surgical procedures and the pipetting microneedle were developed and optimized. The TEES procedures included tympanic cavity visualization, RWM exposure, stapes footplate perforation, and trans-RWM microinjection.

Fabrication of Novel Porous Nano-pesticides by Modifying MPN onto Cu-TCPP MOFs to Enhance Bactericidal Efficacy and Modulate Its Bioavailability.

Nano-pesticides have attracted much attention in the field of agriculture, due to existing problems such as decreased bactericidal effect and poor adhesion. An environmentally friendly metal porphyrin (Cu-TCPP)-based nanocarrier pesticide release of diniconazole (DIN) was designed to enhance bactericidal efficacy and modulate its bioavailability in a multidimensional manner by constructing a metal phenolic network (MPN) encapsulation. The introduction of the MPN prevents the DIN from prematurely escaping from the Cu-TCPP@DIN@MPN in the environment and gives it strong interfacial adhesion to resist rain washing.
