Characterising the change rule of freshness and inorganic anions in reconstituted tobacco pulp with oscillation time.

In order to study the change rule of freshness and acid ions in reconstituted tobacco slurry, the content changes of 17 organic acids and 5 inorganic anions in reconstituted tobacco slurry with different residence times under confined condition were determined by on-line solid-phase extraction ion chromatography in this study. The results showed that the changes of acetic acid, nitrate ion and isovaleric acid in different reconstituted tobacco slurries with oscillation time were regular and consistent, and the trends of the changes of acetic acid, nitrate ion and isovaleric acid in different reconstituted tobacco slurries with oscillation time were correlated with each other in a highly significant way. Taking the evaluation of olfactory aroma and sensory quality qualities of reconstituted tobacco pulps with different residence times as a benchmark, it was found that the variation patterns of nitrate ions and isovaleric acid in reconstituted tobacco pulps with oscillation time were consistent with the variation patterns of olfactory and sensory qualities in the process of closed oscillation; compared with the fresh pulp, the olfactory aroma and sensory qualities of tobacco pulps had unpleasant odours appearing when the content of nitrate ions was reduced by about 48%.

Difference in fecal and oral microbiota between pancreatic cancer and benign/low-grade malignant tumor patients.

Background: Significant gaps exist in understanding the gastrointestinal microbiota in patients with pancreatic cancer (PCA) versus benign or low-grade malignant pancreatic tumors (NPCA). This study aimed to analyze these microbiota characteristics and explore their potential use in distinguishing malignant pancreatic lesions.

Methods: Between September 2020 and May 2024, fecal and oral samples were collected from 121 patients undergoing surgical resection or diagnostic biopsy of pancreatic lesions, including 75 patients with PCA and 46 patients with NPCA, and 16s rRNA sequencing was performed.

Preparation of Flame-Retardant Glass Fiber-Reinforced Epoxy by Vacuum-Assisted Resin Infusion Process with Deep Eutectic Point Curing Agent.

Enhancing the flame resistance of fiber-reinforced epoxy resins will broaden its potential applications. However, the inclusion of a flame retardant in epoxy resins with a curing agent shortens the process, posing a challenge for the production of flame-retardant composites. In this work, the process performance of flame-retardant epoxy resins was improved by using deep eutectic solvents (DES) as the curing agent.

Strain-induced charge delocalization achieves ultralow exciton binding energy toward efficient photocatalysis.

The exciton effect is commonly observed in photocatalysts, where substantial exciton binding energy ( ) significantly hampers the efficient generation of photo-excited electron-hole pairs, thereby severely constraining photocatalysis. Herein, we propose a strategy to reduce through strain-induced charge delocalization. Taking TaO as a prototype, tensile strain was introduced by engineering a crystalline/amorphous interface, weakening the interaction between Ta 5d and O 2p orbitals, thus endowing a delocalized charge transport and significantly lowering .

One-step high-speed thermal-electric aerosol printing of piezoelectric bio-organic films for wirelessly powering bioelectronics.

Piezoelectric biomaterials hold a pivotal role in the progression of bioelectronics and biomedicine, owing to their remarkable electromechanical properties, biocompatibility, and bioresorbability. However, their technological potential is restrained by certain challenges, including precise manipulation of nanobiomolecules, controlling their growth across nano-to-macro hierarchy, and tuning desirable mechanical properties. We report a high-speed thermal-electric driven aerosol (TEA) printing method capable of fabricating piezoelectric biofilms in a singular step.

Intratumoral CXCL13 CD160 CD8 T cells promote the formation of tertiary lymphoid structures to enhance the efficacy of immunotherapy in advanced gastric cancer.

Background: Stage IV gastric cancer is a highly heterogeneous and lethal tumor with few therapeutic strategies. The combination of programmed cell death protein 1 inhibitors and chemotherapy is currently the standard frontline treatment regimen for advanced gastric cancer. Nevertheless, it remains a great challenge to screen the beneficiaries of immunochemotherapy and expand indications for this treatment regimen.

Comparisons of laparoscopic and robotic pancreaticoduodenectomy using barbed and conventional sutures for pancreaticojejunostomy: a propensity score matching study.

Background: There are limited data on the effect of different sutures and surgical approaches on the quality of pancreaticojejunostomy in minimally invasive pancreaticoduodenectomy (MIPD). This study compares the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) between the use of barbed sutures (BSs) and conventional sutures (CSs).

Methods: A retrospective cohort study was conducted on 253 consecutive patients who had undergone MIPD from July 2016 to April 2023.

A bibliometric analysis of follicular thyroid carcinoma: Current situation, hot spots, and global trends.

Background: Follicular thyroid carcinoma (FTC), the second most prevalent thyroid cancer after papillary thyroid cancer (PTC), tends to metastasize distantly, leading to poorer outcomes. Despite substantial research, a holistic bibliometric analysis of FTC literature is lacking. This study aims to fill this gap by employing bibliometric methods to track FTC research evolution.

Learning curve of robotic pancreatoduodenectomy by a single surgeon with extensive laparoscopic pancreatoduodenectomy experience.

With the development of robotic systems, robotic pancreatoduodenectomies (RPDs) have been increasingly performed. However, the number of cases required by surgeons with extensive laparoscopic pancreatoduodenectomy (LPD) experience to overcome the learning curve of RPD remains unclear. Therefore, we aimed to analyze and explore the impact of different phases of the learning curve of RPD on perioperative outcomes.

In vivo detection of the epimer metabolites of sweroside via ultra-performance liquid chromatography time-of-flight mass spectrometry combined with DNPH derivatization.

The metabolites of sweroside were first investigated in vivo with ultra-performance liquid chromatography time-of-flight mass spectrometry (UPLC-TOF-MS) in combination with 2,4-dinitrophenylhydrazine derivatization. In addition, the mass detection sensitivity of the major metabolites, epinaucledal and naucledal, via UPLC-TOF-MS was significantly enhanced, and the epimer metabolites were distinctly discovered from plasma following gavage of sweroside in rats. The plasma concentration of epinaucledal and naucledal was quantified via UPLC-TOF-MS in negative mode using erythrocentaurin as the internal standard.
