Structural Basis for Monomer-Dimer Transition of Dri1 Upon Heme Binding.

Domain related to iron (DRI) contains approximately 90 residues and is involved in iron and heme metabolism. Recent discoveries have annotated Dri1, a DRI-only protein from the cyanobacterium Synechocystis, as a regulator of succinate dehydrogenase in a b-type heme-dependent manner or as a c-type heme oxygenase. Here, we report high-resolution structures of Dri1 in complex with b-type and c-type hemes, respectively.

A novel annexin dimer targets microglial phagocytosis of astrocytes to protect the brain-blood barrier after cerebral ischemia.

Despite the vital role of astrocytes in preserving blood-brain barrier (BBB) integrity, their therapeutic potential as targets in ischemic stroke-induced barrier disruption remains underexplored. We previously reported externalization of phosphatidylserine (PS) on astrocytic membranes concurrent with the emergence of PS externalization in neurons. PS externalization of astrocytes induced microglial phagocytosis of astrocytes, resulting in reduced astrocyte-vascular coupling and subsequent BBB breakdown.

Objectives: To explore the value of T1 mapping-based whole-liver histogram analysis on gadoxetic acid-enhanced MRI for predicting post-hepatectomy liver failure (PHLF).

Methods: Consecutive patients from March 2016 to March 2018 who underwent gadoxetic acid-enhanced MRI in our hospital were retrospectively analyzed, and 37 patients were enrolled. Whole-liver T1 mapping-based histogram analysis was performed.

[Effect of Pterostilbene Regulating Nuclear Factor E2-Related Factor 2 on Apoptosis of Colon Cancer Cells ].

Objective To investigate the effects of pterostilbene on human colon cancer LoVo cells and study the regulatory mechanism of nuclear factor E2-related factor 2 (Nrf2) in the process of pterostilbene acting on LoVo cells. Methods LoVo cells were treated with different concentrations (5,10,20,40,60,80,100 μmol/L) of pterostilbene.Cell viability,migration,invasion,and apoptosis were examined by CCK-8,scratch,Transwell,and TUNEL assays,respectively.

Global research landscape of Peutz-Jeghers syndrome and successful endoscopic management of intestinal intussusception in patients with recurrent laparotomies.

Background: Peutz-Jeghers syndrome (PJS) has brought significant physical, psychological and economic burdens on the patients and their families due to its early onset, diagnostic and therapeutic challenges and increased recurrence risk.

Aim: To explore the current research status and emerging hotspots of PJS.

Methods: Studies on PJS published during 1994-2023 were gathered based on Web of Science Core Collection.

[Pathogenesis of benign prostatic hyperplasia from the perspective of syndrome differentiation of viscera based on the neuro-endocrine-immune network].

According to the theory of traditional Chinese medicine (TCM), benign prostatic hyperplasia (BPH) belongs to the category of "Jing Long". Clinical management of BPH in TCM is root-aimed and kidney-targeted, in combination with the treatment of other viscera based on the syndrome differentiation of zang-fu organs. The neuro-endocrine-immune network of modern medicine is similar to the holistic concept of TCM.

Cardioprotection of voluntary exercise against breast cancer-induced cardiac injury via STAT3.

Exercise is an effective way to alleviate breast cancer-induced cardiac injury to a certain extent. However, whether voluntary exercise (VE) activates cardiac signal transducer and activator of transcription 3 (STAT3) and the underlying mechanisms remain unclear. This study investigated the role of STAT3-microRNA(miRNA)-targeted protein axis in VE against breast cancer-induced cardiac injury.

Mining the interpretable prognostic features from pathological image of intrahepatic cholangiocarcinoma using multi-modal deep learning.

Background: The advances in deep learning-based pathological image analysis have invoked tremendous insights into cancer prognostication. Still, lack of interpretability remains a significant barrier to clinical application.

Methods: We established an integrative prognostic neural network for intrahepatic cholangiocarcinoma (iCCA), towards a comprehensive evaluation of both architectural and fine-grained information from whole-slide images.

Immune cells: potential carriers or agents for drug delivery to the central nervous system.

Drug delivery systems (DDS) have recently emerged as a promising approach for the unique advantages of drug protection and targeted delivery. However, the access of nanoparticles/drugs to the central nervous system (CNS) remains a challenge mainly due to the obstruction from brain barriers. Immune cells infiltrating the CNS in the pathological state have inspired the development of strategies for CNS foundation drug delivery.

Effect of different non-pharmacologic placebo treatments on migraine prevention: a network meta-analysis of randomized controlled trials.

Background: Placebo control plays an important role in evaluating the effectiveness of interventions. Specifying differential effects of various placebo controls on migraine prevention would be essential in the explanation of preventive treatment for migraine and the indirect comparison between different prophylactic therapeutics.

Objectives: To access the impact of different non-pharmacologic placebo types on different outcomes in migraine patients.

Crystallographic and functional studies of a plant temperature-induced lipocalin.

Arabidopsis thaliana temperature-induced lipocalin (AtTIL) is a prototypical member of plant lipocalins and participates in a variety of cellular processes, particularly stress responses. Bioinformatical and physiological studies have proposed its promiscuous ligand-binding ability, but the molecular basis is yet unclear. Here, we report the 1.

International experts consensus guidelines on robotic liver resection in 2023.

The robotic liver resection (RLR) has been increasingly applied in recent years and its benefits shown in some aspects owing to the technical advancement of robotic surgical system, however, controversies still exist. Based on the foundation of the previous consensus statement, this new consensus document aimed to update clinical recommendations and provide guidance to improve the outcomes of RLR clinical practice. The guideline steering group and guideline expert group were formed by 29 international experts of liver surgery and evidence-based medicine (EBM).

Probiotics for the management of irritable bowel syndrome: a systematic review and three-level meta-analysis.

Objective: Previous systematic reviews demonstrated a potentially beneficial effect of probiotics on irritable bowel syndrome (IBS). However, these studies are either affected by the inclusion of insufficient trials or by the problem of dependent data across multiple outcomes, and an overall effect size has not been provided. We aimed to determine the effect of probiotics on IBS through a three-level meta-analysis and clarify potential effect moderators.

AI-predicted mpMRI image features for the prediction of clinically significant prostate cancer.

Purpose: To evaluate the feasibility of using mpMRI image features predicted by AI algorithms in the prediction of clinically significant prostate cancer (csPCa).

Materials And Methods: This study analyzed patients who underwent prostate mpMRI and radical prostatectomy (RP) at the Affiliated Hospital of Jiaxing University between November 2017 and December 2022.

From Centrosymmetry to Noncentrosymmetry: Precise Structural Regulation and Characterization on ZnHPO·2HO Polymorphs.

Polymorphs of ZnHPO·2HO with centrosymmetry () and noncentrosymmetry (2) structures were prepared by modified solution evaporation and seed-crystal-induced secondary nucleation methods. In -ZnHPO·2HO, the zinc atoms are only octahedrally coordinated, while in 2-ZnHPO·2HO, they feature both tetrahedral and octahedral coordination. As a result, -ZnHPO·2HO features a 2D layered structure with lattice water molecules located in the interlayer space, while 2-ZnHPO·2HO features a 3D electroneutral framework of topology connected by Zn(1)O, Zn(2)O, and HPO units.

Efficacy of acupuncture for tension-type headache prophylaxis: systematic review and meta-analysis with trial sequential analysis.

Background: Acupuncture has been shown to reduce tension-type headache (TTH) frequency in previous studies. Nevertheless, repeated significance testing might inflate type I error. We aimed to verify the effectiveness and safety of acupuncture in reducing TTH frequency by meta-analysis and trial sequential analysis (TSA).
