miR-199a-3p mitigates simulated microgravity-induced cardiac remodeling by targeting MEF2C.

Microgravity-induced cardiac remodeling and dysfunction present significant challenges to long-term spaceflight, highlighting the urgent need to elucidate the underlying molecular mechanisms and develop precise countermeasures. Previous studies have outlined the important role of miRNAs in cardiovascular disease progression, with miR-199a-3p playing a crucial role in myocardial injury repair and the maintenance of cardiac function. However, the specific role and expression pattern of miR-199a-3p in microgravity-induced cardiac remodeling remain unclear.

Moral distress, attitude toward death, and palliative care core competencies among ICU nurses: a cross-sectional study.

Background: Palliative care is becoming more widely acknowledged as a crucial part of intensive care for all patients with life-threatening illnesses. Intensive care unit (ICU) nurses regard as a lead role to facilitate this integration, which require nurses to possess professional and comprehensive core competencies. However, there is little knowledge about the palliative care core competencies among ICU nurses.

Integrated GelMA and liposome composite hydrogel with effective coupling of angiogenesis and osteogenesis for promoting bone regeneration.

In clinical scenarios, bone defects stemming from trauma, infections, degenerative diseases, or hereditary conditions necessitate considerable bone grafts. Researchers ardently focus on creating diverse biomaterials to expedite and enhance these intricate restorative processes. These biomaterials play a pivotal role in aiding osteogenesis and angiogenesis factors for reconstructing stable, fully developed bone tissue.

Light-activated photosensitizer/quercetin co-loaded extracellular vesicles for precise oral squamous cell carcinoma therapy.

Oral squamous cell carcinoma (OSCC) is the most common subtype of head and neck malignancies, characterized by a five-year survival rate that remains persistently below 50%, indicative of limited progress in therapeutic interventions. There is an urgent imperative to develop innovative therapeutic strategies, warranting the investigation of advanced treatment modalities. Nanocarriers offer a promising avenue by significantly enhancing drug properties and pharmacokinetics.

Punicalagin inhibits neuron ferroptosis and secondary neuroinflammation to promote spinal cord injury recovery.

Spinal cord injury (SCI) represents a severe type of central nervous system damage, with no effective treatment currently available, partly due to neuronal ferroptosis and subsequent neuroinflammation. Punicalagin, an anti-inflammatory compound extracted from pomegranate peel, has exhibited therapeutic potential for inflammatory diseases. In this study, we present evidence that punicalagin facilitates the recovery of neurological function following SCI by mitigating neuronal ferroptosis.

Youthful Stem Cell Microenvironments: Rejuvenating Aged Bone Repair Through Mitochondrial Homeostasis Remodeling.

Extracellular matrix (ECM) derived from mesenchymal stem cells regulates antioxidant properties and bone metabolism by providing a favorable extracellular microenvironment. However, its functional role and molecular mechanism in mitochondrial function regulation and aged bone regeneration remain insufficiently elucidated. This proteomic analysis has revealed a greater abundance of proteins supporting mitochondrial function in the young ECM (Y-ECM) secreted by young bone marrow-derived mesenchymal stem cells (BMMSCs) compared to the aged ECM (A-ECM).

Epidemiological characteristics of community-acquired pneumoniae in hospitalized children around COVID-19 from Jiangsu Province, China: a multicenter retrospective study.

Background: It has been reported that the emergence of coronavirus disease 2019 (COVID-19) has changed the epidemiological characteristics of many pathogens, but the epidemiological characteristics of (MP) infection in hospitalized children with community-acquired pneumonia (CAP) are not clear. The aim of this study was to answer this question.

Methods: Children with CAP in three tertiary hospitals (hospitals A, B and C) from 2018 to 2023 were selected.

Clinical characteristics and surgical outcomes of 72 cases of intestinal and urinary tract deep infiltrating endometriosis.

The diagnosis and treatment of intestinal and urinary tract deep infiltrating endometriosis (DIE) remain challenging due to its multiple lesions and nonspecific symptoms and signs.

Ketogenic diet and cancer: multidimensional exploration and research.

The ketogenic diet (KD) has attracted attention in recent years for its potential anticancer effects. KD is a dietary structure of high fat, moderate protein, and extremely low carbohydrate content. Originally introduced as a treatment for epilepsy, KD has been widely applied in weight loss programs and the management of metabolic diseases.

Leptin increases chemosensitivity by inhibiting in colorectal cancer cells.

Background: Chemoresistance is a major cause of treatment failure in advanced colorectal cancer (CRC), severely impacting patient survival and quality of life. While conventional chemotherapy regimens can somewhat control tumor progression, their effectiveness is frequently compromised by the development of drug resistance in cancer cells. The aim of this study is to verify and elucidate the specific mechanisms by which leptin enhances chemosensitivity in CRC, providing valuable insights for the development of new combination chemotherapy options.

Endoscope-assisted transcranial surgery for complex pituitary adenoma: a retrospective case series study with propensity score matching.

Surgical treatment of complex pituitary adenomas (PAs) presents a significant challenge. Here in, we compared the surgical outcomes between patients undergoing endoscope-assisted transcranial surgery and microscopic regimens to assess the safety and efficacy of endoscope-assisted transcranial surgery in treating complex PA. This retrospective case-control study was conducted at the First Affiliated Hospital of Soochow University, China.

Targeting FOXM1 condensates reduces breast tumour growth and metastasis.

Identifying phase-separated structures remains challenging, and effective intervention methods are currently lacking. Here we screened for phase-separated proteins in breast tumour cells and identified forkhead (FKH) box protein M1 (FOXM1) as the most prominent candidate. Oncogenic FOXM1 underwent liquid-liquid phase separation (LLPS) with FKH consensus DNA element, and compartmentalized the transcription apparatus in the nucleus, thereby sustaining chromatin accessibility and super-enhancer landscapes crucial for tumour metastatic outgrowth.

CD38-mediated oxytocin signaling in paraventricular nucleus contributes to empathic pain.

Empathy plays a crucial role in social communication and the perception of affective states and behavioral processes. In this study, we observed that empathic interaction with a mouse experiencing pain resulted in decreased mechanical pain thresholds and anxiety-like behaviors in its bystander, though the underlying mechanisms remain unknown. We demonstrated that CD38 expression in the paraventricular nucleus (PVN) was upregulated during empathic pain, and the pain and emotions of CD38 knockout (CD38KO) mice as bystanders were not affected.
