Zhizhu pills (ZZP) is a Traditional Chinese Medicine that has been extensively applied in the treatment of spleen deficiency and constipation for many years. As a commonly used prescription in Traditional Chinese medicine, there had been a controversy over whether to use raw Rhizoma Atractylodis Macrocephalae (RRAM) or Bran-Fired Rhizoma Atractylodis Macrocephalae (BRAM) in ZZP. In this study, a specific, sensitive, fast and accurate liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed to analyze the main active components in ZZP.

Article Synopsis
  • Automated polyp segmentation in colonoscopy images is critical for detecting colorectal cancer but faces challenges like the variability of polyps and limited annotated data, along with difficulties from concealed polyps blending into surrounding tissues.
  • To address these issues, the Highlighted Diffusion Model Plus (HDM+) framework has been developed, which consists of two stages: the first focuses on training with highlighted ground-truth data to improve segmentation accuracy, while the second utilizes features from the trained model to enhance efficiency.
  • Experiments on multiple polyp segmentation benchmarks show that the HDM+ significantly improves the effectiveness of polyp detection, tackling the problems posed by domain gaps and enhancing performance in segmentation tasks.

  • The study aimed to compare the long-term quality of life (QoL) between survivors of nasopharyngeal carcinoma (NPC) who were children versus adults, and to identify clinical factors influencing QoL.
  • A total of 420 NPC survivors (195 paediatric and 225 adult) participated, all having survived at least 8 years post-treatment with intensity-modulated radiotherapy (IMRT).
  • Results indicated that paediatric survivors reported better QoL scores across several areas, such as global health, physical function, and social function, but had lower cognitive function compared to adults; different clinical factors were linked to QoL in each group.*

The electroless nickel spent tank liquid (ENSTL), as a typical hazardous waste, contains a variety of refractory organic substances as well as heavy metals and inorganic salts. Generally, ENSTL is delegated for disposing by qualified hazardous waste disposal departments in China. However, the temporary storage, transportation, and higher entrusted disposal expenses increase the burden on enterprises producing the hazardous ENSTL.

  • Traditional methods for designing superhalogens involve modifying clusters to control electron count, which can be complex and difficult to manage in experiments.
  • This study introduces the concept of using oriented external electric fields (OEEF) to increase the electron affinity of aluminum-based metal clusters without changing their internal structure.
  • The findings present a new, less invasive way to create superhalogens and superalkalis, expanding possibilities for practical applications of functional clusters.

  • The TaO cluster, a non-noble metal, shows potential as an alternative to noble metals like gold, enabling the development of customized materials through the superatom concept.
  • Density functional theory calculations reveal that TaO clusters have the highest electron affinity at 2.14 eV, with enhancements through the integration of CO ligands and oriented external electric fields (OEEF).
  • By applying OEEF, researchers increased the electron affinity of CO-ligated TaO clusters significantly, highlighting a new strategy for creating superhalogens, which can potentially revolutionize material engineering.

Motivation: Enhanced by contemporary computational advances, the prediction of drug-target interactions (DTIs) has become crucial in developing de novo and effective drugs. Existing deep learning approaches to DTI prediction are frequently beleaguered by a tendency to overfit specific molecular representations, which significantly impedes their predictive reliability and utility in novel drug discovery contexts. Furthermore, existing DTI networks often disregard the molecular size variance between macro molecules (targets) and micro molecules (drugs) by treating them at an equivalent scale that undermines the accurate elucidation of their interaction.

The variety of highly efficient red/near-infrared (NIR) materials with thermally activated delayed fluorescence (TADF) feature is extremely limited so far, and it is necessary to expand the candidate pool of excellent red/deep-red emitters. However, how to control the energy level alignment of the CT (singlet charge transfer) state and the LE (triplet local excitation) state to improve the emission efficiency of materials remains a challenge. Herein, based on our previously reported green fluorescent material 67dTPA-FQ, three new donor-acceptor type TADF materials (TQ-oMeOTPA, TsQ-oMeOTPA and SQ-oMeOTPA) were designed by introducing 4,4'-dimethoxy triphenylamine (MeOTPA) as the donor, and introduced S atoms on the acceptors to enhance the spin-orbit coupling (SOC) and CT effects.

Growing evidence has found the health protective effects of greenness exposure on tuberculosis (TB) and the impact of ambient air pollutants on TB drug-resistance. However, it remains unclear whether residential greenness is also beneficial to reduce TB drug-resistance, and whether air pollution modify the greenness-TB resistance relationship. We enrolled 5006 newly-diagnosed TB patients from Shandong, China, during 2014 to 2021.

Coastal wetlands are important carbon sinks, and they contribute to reducing the effects of global warming. This study used the eddy covariance method to detect the CO flux in the restoration wetland of the Liaohe River estuary in 2021 and investigate the characteristics of ecosystem CO exchange and its environmental control factors. The aim was to assess the carbon source/sink capacity of salt marshes in the restored area and to provide data support and theoretical basis for evaluating the effectiveness of ecological restoration projects.

Remote Photoplethysmography (rPPG) has been attracting increasing attention due to its potential in a wide range of application scenarios such as physical training, clinical monitoring, and face anti-spoofing. On top of conventional solutions, deep-learning approach starts to dominate in rPPG estimation and achieves top-level performance. However, most of them try to integrate preprocessing steps such as the ROI selection into an end-to-end network, which may diverge the attention and also limit the generalization in other scenarios with different input skin regions.

Programmed cell death protein 1 (PD-1) immune checkpoint blockade therapy has revolutionized cancer treatment. Although PD-1 blockade is effective in a subset of patients with cancer, many fail to respond because of either primary or acquired resistance. Thus, next-generation strategies are needed to expand the depth and breadth of clinical responses.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) disrupts the blood-testis barrier (BTB), resulting in alterations in spermatogenesis. However, whether BTB-related proteins (such as ZO-1, claudin11, N-cadherin, and CX43) are targeted by SARS-CoV-2 remains to be clarified. BTB is a physical barrier between the blood vessels and the seminiferous tubules of the animal testis, and it is one of the tightest blood-tissue barriers in the mammalian body.

Laser ablation ICP-MS (LA-ICP-MS) is a powerful microbeam technique capable of rapid and precise determination for a large spectrum of trace elements at ppm or sub-ppm levels. Micrometer-scale minerals and inclusions are very common in geological materials, for which direct measurement is restricted by the spot size using LA-ICP-MS (generally 20-50 μm). In this study, ilmenite lamellae intergrown with magnetite were selected as an example to describe a practical algorithm that applies regression analysis to extract the chemical compositions of binary phases from mixed LA-ICP-MS signals.

Phaeocystis is a globally distributed Prymnesiophyte genus and usually forms massive harmful colony blooms, which impact marine ecosystem, mariculture, human health, and even threaten coastal nuclear power plant safety. However, the mechanisms behind the colony formation from the solitary cells remain poorly understood. Here, we investigated metabolic processes of both solitary and non-flagellated colonial cells of Phaeocystis globosa at different colony bloom stages in the subtropical Beibu Gulf using a metaproteomic approach.
