Enhanced photocatalytic performance in seawater of donor-acceptor type conjugated polymers through introduction of alkoxy groups in the side chain.

Previous studies have demonstrated that the donor (D)-acceptor (A) structure enables conjugated polymers (CPs) to effectively inhibit charge recombination, reduce exciton binding energy to a minimum, and broaden the light absorption spectrum, ultimately enhancing photocatalytic activity. Besides, side chain engineering is an effective approach to enhance photocatalytic performance by regulating surface chemistry and energy band structure of CPs. Herein, three D-A type CPs, namely TPD-T, TPD-MOT and TPD-DOT, were designed and synthesized using thieno[3,4-c]pyrrole-4,6-dione (TPD) as A units and thiophene with different alkyl/alkoxy groups side chain (as 3-octylthiophene (T), 3-methoxythiophene (MOT) and 3,4-ethylenedioxythiophene (DOT)) as D units, via an atom- and step-economic CH/CH cross-coupling polycondensation.

Releasing characteristics and risk of micro/nanoplastics from Chinese herbal decoction packages under daily usage scenarios.

The single-use plastic packaging for traditional Chinese herbal decoction is prevalent for its convenience. However, concerns have been raised regarding the biosafety implications of dissolved plastic particles from such food contact materials and their potential impact on drug efficacy. To initially investigate the release characteristics of micro/nanoplastics (M/NPs) from Chinese herbal decoction packages under different usage scenarios, 100 mL of water was filled at temperatures ranging from 40 ℃ to 100 ℃ and stored at 4 ℃ for 1 to 14 days before reheating at 60 ℃ prior to consumption.

Cr-doped NiFe sulfides nanoplate array: Highly efficient and robust bifunctional electrocatalyst for the overall water splitting and seawater electrolysis.

To replace precious metals and reduce production costs for large-scale hydrogen production, developing stable, high-performance transition metal electrocatalysts that can be used in a wide range of environments is desirable yet challenging. Herein, a self-supported hybrid catalyst (NiFeCrS/NF) with high electrocatalytic activity was designed and constructed using conductive nickel foam as a substrate via manipulation of the cation doping ratio of transition metal compounds. Due to the strong coupling synergy between the metal sulfides NiS, FeS, and CrS, as well as their interaction with the conductive nickel foam (NF), the energy barrier for catalytic reactions is reduced, and the charge transfer rate is enhanced.

Ultrasensitive InO-Based Nanoflakes for Lung Cancer Diagnosis and the Sensing Mechanism Investigated by Spectroscopy.

Rapid gas sensing with high sensitivity and selectivity is pivotal in advanced production, in smart living, and increasingly in medical health applications. This study presents a novel Pt@InNiO nanoflake isoprene sensor that achieves an exceptionally low limit of detection (LOD) at 2 ppb, the lowest reported for isoprene sensors to date. Notably, it exhibits high selectivity and remarkable antihumidity capacity, thus meeting the stringent requirements for lung cancer screening.

Constructing a nomogram to predict overall survival of colon cancer based on computed tomography characteristics and clinicopathological factors.

Background: The colon cancer prognosis is influenced by multiple factors, including clinical, pathological, and non-biological factors. However, only a few studies have focused on computed tomography (CT) imaging features. Therefore, this study aims to predict the prognosis of patients with colon cancer by combining CT imaging features with clinical and pathological characteristics, and establishes a nomogram to provide critical guidance for the individualized treatment.

The Correlation Between Essential Amino Acid Tryptophan, Lysine, Phenylalanine and Chemotherapy of Breast Cancer.

To investigate the differences in serum tryptophan, lysine, and phenylalanine levels in breast cancer patients, the correlation between the three amino acids with the chemotherapy regimen, and their significance in the clinical diagnosis and treatment of breast cancer.Clinical data were collected from the Department of Breast Surgery at Yunnan Cancer Hospital, encompassing 216 cases from July to December 2020, including 91 healthy individuals, 38 with benign tumors, and 87 with cancer. Amino acid levels were measured using liquid chromatography-tandem mass spectrometry.

Neural Representations of Emotions in Visual, Auditory, and Modality-Independent Regions Reflect Idiosyncratic Conceptual Knowledge.

Growing evidence suggests that conceptual knowledge influences emotion perception, yet the neural mechanisms underlying this effect are not fully understood. Recent studies have shown that brain representations of facial emotion categories in visual-perceptual areas are predicted by conceptual knowledge, but it remains to be seen if auditory regions are similarly affected. Moreover, it is not fully clear whether these conceptual influences operate at a modality-independent level.

Rapid yet Controlled Synthesis of 2D Covalent Organic Framework Nanocapsules as High-Performance Photocatalytic Carriers.

Synthesis and assembly of two-dimensional (2D) polymeric materials present a tricky trade-off between the high reaction rate and precise morphology control. Here we report a nanoconfined synthesis of imine-based 2D covalent organic frameworks (COFs) at the interface of oil-in-water (O/W) emulsion droplets stabilized by cationic surfactants. Highly uniform nanocapsules (NCs) could be prepared without adding extra catalysts at room temperature in just 4.

Effectiveness of electro-acupuncture for cognitive improvement on Alzheimer's disease quantified via PET imaging of sphingosine-1-phosphate receptor 1.

Introduction: Electro-acupuncture (EA) has demonstrated potential in improving mild-to-moderate dementia in clinics, but the underlying scientific target remains unclear.

Methods: EA was administered to APP/PS1 Alzheimer's disease (AD) mice, with untreated AD, and wild type (WT) mice serving as controls. The efficacy of EA was assessed by the Morris water maze cognitive functional tests.

Temporal trend and attributable risk factors of Alzheimer's disease and other dementias burden in China: Findings from the Global Burden of Disease Study 2021.

Introduction: We examined the burden of Alzheimer's disease and other dementias (ADOD) and attributable factors at the national and provincial levels in China.

Methods: Using the Global Burden of Diseases Study 2021, we estimated incidence, prevalence, mortality rate, disability-adjusted life years (DALYs), and the ratio of years lived with disability (YLD) to DALYs for ADOD in China. Estimated annual percentage changes (EAPCs) were used to quantify the temporal trends from 1990 to 2021.

GBFNN: Generalized geodesic basis function neural network.

Real-world data is typically distributed on low-dimensional manifolds embedded in high-dimensional Euclidean spaces. Accurately extracting spatial distribution features on general manifolds that reflect the intrinsic characteristics of data is crucial for effective feature representation. Therefore, we propose a generalized geodesic basis function neural network (GBFNN) architecture.
