Fabrication of apigenin and adenosine-loaded nanoparticles against doxorubicin-induced myocardial infarction by reducing inflammation and oxidative stress.

The study's goals are to fabricate PLGA nanoparticles (PNPs) loaded with apigenin (AP) and adenosine (AD) using a microfluidic preparation method to a standard emulsification method and investigate the possible heart-protective effects of AP-AD PNPs made using the emulsification method. Compared to microfluidics, the emulsification method fabricated small-size nanoparticles, which are better at encapsulating drugs, retaining more drugs, and having a low viscosity for the myocardial infarction (MI) injection. TheMI model was developed using SD rats injected under the skin with 85 mg/kg doxorubicin (DOX) for 2 days.

STZ-induced gestational diabetes exposure alters PTEN/AKT/mTOR-mediated autophagy signaling pathway leading to increase the risk of neonatal hypoxic-ischemic encephalopathy.

Exposure to gestational diabetes mellitus (GDM) during pregnancy has significant consequences for the unborn baby and newborn infant. However, whether and how GDM exposure induces the development of neonatal brain hypoxia/ischemia-sensitive phenotype and the underlying molecular mechanisms remain unclear. In this study, we used a late GDM rat model induced by administration of streptozotocin (STZ) on gestational day 12 and investigated its effects of GDM on neonatal brain development.

Adaptive radiation strategy with V20 limitation associates with survival benefit and lower incidence of symptomatic radiation pneumonitis in stage III NSCLC patients receiving concurrent immunotherapy and thoracic radiation.

Objectives: To evaluate the efficacy and the incidence of symptomatic radiation pneumonitis (RP) of the adaptive radiation strategy with V20 limitation in stage III non-small cell lung cancer (NSCLC) patients receiving concurrent immunotherapy and radiotherapy Materials and Methods: We retrospectively reviewed stage III NSCLC patients received thoracic radiation with or without immunotherapy from January 2015 to September 2024 in the Third Xiangya Hospital. The overall survival (OS), progression free survival (PFS), objective response rate (ORR), and the incidence of symptomatic RP were compared among patients stratified by the sequential of immunotherapy and radiotherapy.

Results: 45 patients received concurrent immunotherapy and radiotherapy with application of the adaptive radiation strategy (the CIR group).

ANGPTL3 as a target for treating lipid disorders in type 2 diabetes patients.

Type 2 diabetes mellitus (T2DM) is a globally prevalent metabolic disorder, and cardiovascular disease (CVD) is a significant cause of mortality and morbidity in diabetic individuals. In addition to hyperglycemia, lipid abnormalities associated with T2DM play a crucial role in the development of CVD complications. Diabetic dyslipidemia is characterized by elevated levels of triglyceride (TG)-rich lipoproteins and small dense low-density lipoprotein (LDL) particles, reduced high-density lipoprotein (HDL) cholesterol, and impaired HDL function.

Association between physical activity and immunosuppressive medication adherence among renal transplant recipients: a case-control study.

Background: Behavioural interventions are closely associated with immunosuppressive medication (IM) adherence. We aimed to explore the relationship between physical activity and IM adherence among renal transplant patients (RTPs) to determine potential interventions to improve IM adherence.

Design: A case-control study.

Sesamol Alleviated Lipotoxicity-Induced Dysfunction in MIN6 Cells via Facilitating Cellular Senescence Caused by Endoplasmic Reticulum Stress.

Obesity is found to be a significant risk factor for type 2 diabetes mellitus (T2DM), attributed to lipotoxicity-induced β-cell dysfunction. However, the specific mechanism involved in the process remains incompletely unclarified. The current study demonstrated lipotoxicity resulted in the activation of ER stress, which increased the protein level of TXNIP, thereby inducing senescence-assiciated dysfunction in MIN6 cells under high fat environment.

Clinical characteristics of idiopathic inflammatory myopathies related to anti-SRP: a single center experience.

Idiopathic inflammatory myopathy (IIM) with autoantibodies recognizing the signal recognition particle (SRP) is characterized by prominent proximal weakness, infrequent extramuscular involvement, dramatically elevated creatine kinase levels, and myofiber necrosis with few inflammatory cell infiltrates in muscle tissue. To enhance understanding of the clinically used diagnosis and treatment of this disease, this study presents a single-center experience and analysis of a Chinese cohort with anti-SRP IIM. The most recent European Neuromuscular Center criteria were used to include Anti-SRP IIM patients from September 2016 to November 2019.

Xanthohumol overcomes osimertinib resistance via governing ubiquitination-modulated Ets-1 turnover.

Non-small cell lung cancer (NSCLC) is a prevalent and fatal malignancy with a significant global impact. Recent advancements have introduced targeted therapies like tyrosine kinase inhibitors (TKIs) such as osimertinib, which have improved patient outcomes, particularly in those with EGFR mutations. Despite these advancements, acquired resistance to TKIs remains a significant challenge.

Beyond clinical trials: CDK4/6 inhibitor efficacy predictors and nomogram model from real-world evidence in metastatic breast cancer.

Background: CDK4/6 inhibitors (CDK4/6i) have shown promising results in the treatment of hormone receptor-positive (HR+) metastatic breast cancer (MBC) when combined with endocrine therapy (ET). It is crucial to evaluate the actual effectiveness and safety of CDK4/6i in clinical practice, as well as to analyze the factors that can predict their outcomes.

Methods: Patients with HR+ MBC who received CDK4/6i-based therapy between May 2016 and May 2023 at Hunan Cancer Hospital were evaluated for progression-free survival (PFS).

The miR-665/SOST Axis Regulates the Phenotypes of Bone Marrow Mesenchymal Stem Cells and Osteoporotic Symptoms in Female Mice.

Osteoporosis is a common degenerative skeletal disease among older people, especially postmenopausal women. Bone marrow mesenchymal stem cells (BMSCs), the progenitors of osteoblasts, are essential to the pathophysiology of osteoporosis. Herein, targeting miRNAs with differential expression in dysfunctional BMSCs was accomplished by bioinformatics analysis based on public databases.

Long-term efficacy and safety of stapokibart for moderate-to-severe atopic dermatitis: 52-week results from a phase 3 trial.

Background: Management of moderate-to-severe atopic dermatitis (AD) needs long-term therapy. Stapokibart is a humanized monoclonal antibody targeting interleukin-4 receptor α subunit (IL-4Rα), a shared receptor for IL-4 and IL-13 which are key pathogenic drivers of AD. In a pivotal phase 3 trial (NCT05265923), significant higher proportions of adult AD patients receiving stapokibart than placebo achieved ≥75% improvement from baseline in Eczema Area and Severity Index (EASI-75; 66.

Widespread Gene Editing in the Brain via In Utero Delivery of mRNA Using Acid-Degradable Lipid Nanoparticles.

In utero gene editing with mRNA-based therapeutics has the potential to revolutionize the treatment of neurodevelopmental disorders. However, a critical bottleneck in clinical application has been the lack of mRNA delivery vehicles that can efficiently transfect cells in the brain. In this report, we demonstrate that in utero intracerebroventricular (ICV) injection of densely PEGylated lipid nanoparticles (ADP-LNPs) containing an acid-degradable PEG-lipid can safely and effectively deliver mRNA for gene editing enzymes to the fetal mouse brain, resulting in successful transfection and editing of brain cells.

Acquired Bortezomib Resistance in Multiple Myeloma: From Mechanisms to Strategy.

Multiple myeloma (MM) is a heterogeneous plasma cell tumor with a survival period of several months to over ten years. Despite the development of various new drugs, MM is still incurable and recurs repeatedly. Bortezomib, a landmark event in the history of MM treatment, has dramatically improved the prognosis of patients with MM.
