Research Progress of M6A Methylation Modification in Immunotherapy of Colorectal Cancer.

Among the Poly(ADP-ribose) Polymerase (PARP) family in mammals, PARP1 is the first identified and well-studied member that plays a critical role in DNA damage repair and has been proven to be an effective target for cancer therapy. Here, we have reviewed not only the role of PARP1 in different DNA damage repair pathways, but also the working mech-anisms of several PARP inhibitors (PARPi), inhibiting Poly-ADP-ribosylation (PARylation) processing and PAR chains production to trap PARP1 on impaired DNA and inducing Tran-scription-replication Conflicts (TRCs) by inhibiting the PARP1 activity. This review has sys-tematically summarized the latest clinical application of six authorized PARPi, including olaparib, rucaparib, niraparib, talazoparib, fuzuloparib and pamiparib, in monotherapy and combination therapies with chemotherapy, radiotherapy, and immunotherapy, in different kinds of cancer.

A prognostic model for lung adenocarcinoma based on cuproptosis and disulfidptosis related genes revealing the key prognostic role of FURIN.

Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer. Despite advances in treatment, the prognosis remains poor due to late diagnosis. Cuproptosis (driven by copper ion accumulation) and disulfidptosis (driven by disulfide bond accumulation) are novel forms of programmed cell death, closely linked to tumor initiation, progression, and resistance.

Incidental diagnosis of familial hypercholesterolaemia in a mother-daughter pair: the underdiagnosis of the disease highlighting the need for universal screening.

Familial hypercholesterolaemia (FH) is a common yet underdiagnosed genetic disorder of low-density lipoprotein metabolism leading to premature cardiovascular disease. Most FH individuals are only diagnosed later in their adulthood, missing the critical window for pre-emptive treatment. The absence of clinical manifestations until adulthood and poor awareness by medical and general communities contribute to this unmet clinical need.

Targeting deubiquitinase USP7-mediated stabilization of XPO1 contributes to the anti-myeloma effects of selinexor.

Background: Targeting exportin1 (XPO1) with Selinexor (SEL) is a promising therapeutic strategy for patients with multiple myeloma (MM). However, intrinsic and acquired drug resistance constitute great challenges. SEL has been reported to promote the degradation of XPO1 protein in tumor cells.

The interconnective role of the UPS and autophagy in the quality control of cancer mitochondria.

Uncontrollable cancer cell growth is characterized by the maintenance of cellular homeostasis through the continuous accumulation of misfolded proteins and damaged organelles. This review delineates the roles of two complementary and synergistic degradation systems, the ubiquitin-proteasome system (UPS) and the autophagy-lysosome system, in the degradation of misfolded proteins and damaged organelles for intracellular recycling. We emphasize the interconnected decision-making processes of degradation systems in maintaining cellular homeostasis, such as the biophysical state of substrates, receptor oligomerization potentials (e.

Omnipotent antibacterial cotton fabrics with superhydrophobic and photothermal properties.

Due to the outbreak of global public health emergency, antibacterial fabrics such as face masks are in great demand. However, common antibacterial fabrics cannot kill bacteria in minutes and they are easy to be contaminated and lost biological activity. In this work, omnipotent antibacterial cotton fabrics with superhydrophobic and photothermal properties are developed by the combination of dopamine with copper sulfide (CuS) and silver nanoparticles on cotton fabrics, and post-modification with PDMS.

However, the quantitative assessment of MR is intricate and time-consuming, posing challenges for physicians in ensuring the precision of the results. Thus, our objective was to create an automated and reproducible artificial intelligence (AI) system.

Impaired Muscle Parameters in Individuals With Premature Ovarian Insufficiency: A Pilot Study.

Context: Although bone loss is a recognized consequence of premature ovarian insufficiency (POI), the impact on skeletal muscle health is less well-defined.

Objective: To compare muscle mass and function parameters between women with POI and controls.

Methods: Cross-sectional study from a tertiary health network and community between 2017 and 2023.

SMURF1 mediates damaged lysosomal homeostasis by ubiquitinating PPP3CB to promote the activation of TFEB.

The calcium-activated phosphatase PPP3/calcineurin dephosphorylates TFEB (transcription factor EB) to trigger its nuclear translocation and the activation of macroautophagic/autophagic targets. However, the detailed molecular mechanism regulating TFEB activation remains poorly understood. Here, we highlighted the importance of SMURF1 (SMAD specific E3 ubiquitin protein ligase 1) in the activation of TFEB for lysosomal homeostasis.

Identification of the Vulnerability of Atherosclerotic Plaques by a Photoacoustic/Ultrasonic Dual-Modal cRGD Nanomolecular Probe.

Objective: To explore the feasibility of using cRGD-GNR-PFP-NPs to assess plaque vulnerability in an atherosclerotic plaque mouse model by dual-modal photoacoustic/ultrasonic imaging.

Methods: A nanomolecular probe containing gold nanorods (GNRs) and perfluoropentane (PFP) coated with the cyclic Arg-Gly-Asp (cRGD) peptide were prepared by double emulsion solvent evaporation and carbodiimide methods. The morphology, particle size, potential, cRGD conjugation and absorption features of the nanomolecular probe were characterized, along with its in vitro phase transformation and photoacoustic/ultrasonic dual-modal imaging properties.

Application of preset coronary artery orifice patch in Bentall surgery.

Background: Bentall surgery is the main method for treating aortic root lesions, but traditional Bentall method is very difficult for patients with mild aortic sinus dilation to directly anastomose the coronary artery orifice with graft.

Case Presentation: A 41-year-old man was admitted to hospital after severe chest pain. Computed tomography angiography(CTA)revealed a type A aortic dissection.

Healthcare system resilience and adaptability to pandemic disruptions in the United States.

Understanding healthcare system resilience has become paramount, particularly in the wake of the COVID-19 pandemic, which imposed unprecedented burdens on healthcare services and severely impacted public health. Resilience is defined as the system's ability to absorb, recover from and adapt to disruptions; however, despite extensive studies on this subject, we still lack empirical evidence and mathematical tools to quantify its adaptability (the ability of the system to adjust to and learn from disruptions). By analyzing millions of patients' electronic medical records across US states, we find that the COVID-19 pandemic caused two successive waves of disruptions within the healthcare systems, enabling natural experiment analysis of the adaptive capacity of each system to adapt to past disruptions.

Identification of microbial communities and multi-species biofilms contamination in seafood processing environments with different hygiene conditions.

Biofilms formed by spoilage and pathogenic bacteria increase microbial persistence, causing an adverse influence on the quality of seafood. The mono-species biofilms are widely reported, however, the contamination of multi-species biofilms and their matrix in food environments are still not fully understood. Here, we assessed the contamination of multi-species biofilms in three seafood processing environments with different hygiene levels by detecting bacterial number and three biofilm matrix components (carbohydrates, extracellular DNA (eDNA), and proteins).

Generative adversarial network-based synthesis of contrast-enhanced MR images from precontrast images for predicting histological characteristics in breast cancer.

. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a sensitive tool for assessing breast cancer by analyzing tumor blood flow, but it requires gadolinium-based contrast agents, which carry risks such as brain retention and astrocyte migration. Contrast-free MRI is thus preferable for patients with renal impairment or who are pregnant.

Optimizing motion imagery classification with limited channels using the common spatial pattern-based integrated algorithm.

The extraction of effective classification features from electroencephalogram (EEG) signals in motor imagery is a popular research topic. The Common Spatial Pattern (CSP) algorithm is widely employed in this field. However, the performance of the traditional CSP method depends significantly on the choice of a specific frequency band and channel number of EEG data.

Occult urothelial carcinoma with mediastinal metastasis: A case report.

Occult urothelial carcinoma (UC), particularly with mediastinal metastases, is an uncommon clinical occurrence. The present study describes the unusual case of a 70-year-old male patient who developed mediastinal metastases from an occult UC. Histological evaluations and immunohistochemical features of the mediastinal tumor were indicative of UC; however, extensive imaging failed to identify the primary urological lesion.

Predicting lung cancer survival prognosis based on the conditional survival bayesian network.

Lung cancer is a leading cause of cancer deaths and imposes an enormous economic burden on patients. It is important to develop an accurate risk assessment model to determine the appropriate treatment for patients after an initial lung cancer diagnosis. The Cox proportional hazards model is mainly employed in survival analysis.

Carnosine supplementation improves glucose control in adults with pre-diabetes and type 2 diabetes: A randomised controlled trial.

Background And Aims: Type 2 diabetes (T2DM) is a major cause of morbidity and mortality globally. Carnosine, a naturally occurring dipeptide, has anti-inflammatory, antioxidant, and anti-glycating effects, with preliminary evidence suggesting it may improve important chronic disease risk factors in adults with cardiometabolic conditions.

Methods And Results: In this randomised controlled trial, 43 adults (30%F) living with prediabetes or T2DM consumed carnosine (2 g) or a matching placebo daily for 14 weeks to evaluate its effect on glucose metabolism assessed via a 2-h 75 g oral glucose tolerance test.

Development and Validation of a Bayesian Network-Based Model for Predicting Coronary Heart Disease Risk From Electronic Health Records.

Background: Traditional risk evaluation models have been applied to guide public health and clinical practice in various studies. However, the application of existing methods to data sets with missing and censored data, as is often the case in electronic health records, requires additional considerations. We aimed to develop and validate a predictive model that exhibits high performance with data sets that contain missing and censored data.

Radiogenomic analysis of cellular tumor-stroma heterogeneity as a prognostic predictor in breast cancer.

Background: The tumor microenvironment and intercellular communication between solid tumors and the surrounding stroma play crucial roles in cancer initiation, progression, and prognosis. Radiomics provides clinically relevant information from radiological images; however, its biological implications in uncovering tumor pathophysiology driven by cellular heterogeneity between the tumor and stroma are largely unknown. We aimed to identify radiogenomic signatures of cellular tumor-stroma heterogeneity (TSH) to improve breast cancer management and prognosis analysis.

Carnosine Did Not Affect Vascular and Metabolic Outcomes in Patients with Prediabetes and Type 2 Diabetes: A 14-Week Randomized Controlled Trial.
