Extracellular vesicles reshape the tumor microenvironment to improve cancer immunotherapy: Current knowledge and future prospects.

Tumor immunotherapy has revolutionized cancer treatment, but limitations remain, including low response rates and immune complications. Extracellular vesicles (EVs) are emerging as a new class of therapeutic agents for various diseases. Recent research shows that changes in the amount and composition of EVs can reshape the tumor microenvironment (TME), potentially improving the effectiveness of immunotherapy.

SIRT3-Mediated Deacetylation of SDHA Rescues Mitochondrial Bioenergetics Contributing to Neuroprotection in Rotenone-Induced PD Models.

Mitochondrial dysfunction is critically involved in the degeneration of dopamine (DA) neurons in the substantia nigra, a common pathological feature of Parkinson's disease (PD). Previous studies have demonstrated that the NAD-dependent acetylase Sirtuin 3 (SIRT3) participates in maintaining mitochondrial function and is downregulated in aging-related neurodegenerative disorders. The exact mechanism of action of SIRT3 on mitochondrial bioenergetics in PD pathogenesis, however, has not been fully described.

Efficacy and tolerability of oxcarbazepine in the treatment of focal epilepsy in neonates and infants under 3 months of age: A single-center retrospective analysis.

Objective: The neonatal and infantile period is the age group with the highest incidence of epilepsy, in which gene variants in sodium and potassium channels are an important etiology, so the sodium channel blocker class of antiseizure medications may be effective in the treatment of early onset epilepsy. This study aimed to summarize the efficacy and tolerability of oxcarbazepine (OXC) in the treatment of focal epilepsy in neonates and infants under 3 months of age.

Methods: A retrospective analysis of children with focal epilepsy onset within 3 months of age and treated with OXC in a tertiary pediatric epilepsy center in China was conducted.

: Exploring Understandings and Experiences of Social and Emotional Learning and Meaningful Physical Education Utilizing Democratic and Reflective Pedagogies.

When it comes to teaching social and affective outcomes pertaining to health and physical activity within Physical Education (PE) settings, such learning historically has been observed as manifesting itself as rather than intentionally-taught-for curricular outcomes. The purpose of this study was to explore understandings and experiences of Social and Emotional Learning (SEL) and Meaningful Physical Education (MPE) utilizing democratic and reflective pedagogies. A qualitative case study design was implemented in an alternative high school setting in the USA across 10 months.

Comparison of four neonatal transport scoring methods in the prediction of mortality risk in full-term, out-born infants: a single-center retrospective cohort study.

Unlabelled: Neonatal transport scoring systems can assess severity before and after transport, improve transport efficiency, and predict the occurrence of critical illness. The aim of this study was to compare four neonatal transport scoring methods to predict mortality risk and clinical utility within the first week after transportation. This was a single-center retrospective cohort study.

"This Is Not Gym": Enacting Student Voice Pedagogies to Promote Social and Emotional Learning and Meaningful Physical Education.

The purpose of this study was to explore learners' experiences enacting youth/student voice pedagogies (SVP) to promote Social and Emotional Learning (SEL) and meaningful physical education (MPE) in an alternative education setting. Drawing on social constructivist learning theory in understanding and implementing a MPE approach, and a systemic framework for SEL, two research questions guided the research process: (1) How did students interpret and enact these pedagogies? (2) What contribution did the enactment of these pedagogies have in promoting SEL and MPE? This study implemented a qualitative case study design framed by a participatory action research (PAR) approach spanning 12 weeks from February to May 2021. Participants in this study included 16 ninth grade alternative high school students (eight girls/eight boys) aged 14-15 who had just returned to face-to-face learning in January 2021 for the first time following COVID-19.

Regulation of SIRT3 on mitochondrial functions and oxidative stress in Parkinson's disease.

Sirtuin-3 (SIRT3) is a NAD-dependent protein deacetylase that is located in mitochondria, regulating mitochondrial proteins and maintaining cellular antioxidant status. Increasing evidence demonstrates that SIRT3 plays a role in degenerative disorders including Parkinson's disease (PD), which is a devastating nervous system disease currently with no effective treatments available. Although the etiology of PD is still largely ambiguous, substantial evidence indicates that mitochondrial dysfunction and oxidative stress play major roles in the pathogenesis of PD.

Endobronchial ultrasound-guided transbronchial needle aspiration combined with either endoscopic ultrasound-guided fine-needle aspiration or endoscopic ultrasound using the EBUS scope-guided fine-needle aspiration for diagnosing and staging mediastinal diseases: a systematic review and meta-analysis.

The present systematic review and meta-analysis aimed to evaluate the available evidence base on endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) combined with either endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) or endoscopic ultrasound using the EBUS scope-guided fine-needle aspiration (EUS-B-FNA) for diagnosing and staging mediastinal diseases. PubMed, Web of Science, and Embase were searched to identify suitable studies up to June 30, 2019. Two investigators independently reviewed articles and extracted relevant data.

Novel enhanced GFP-positive congenic inbred strain establishment and application of tumor-bearing nude mouse model.

Transgenic GFP gene mice are widely used.

Chemokine (C-X-C motif) ligand 14 contributes to lipopolysaccharide-induced fibrogenesis in mouse L929 fibroblasts via modulating PPM1A.

Herein, we found that serum chemokine ligand 14 (CXCL14) was significantly enhanced in patients with idiopathic pulmonary fibrosis (IPF). In our current study, mouse L929 fibroblasts were stimulated with lipopolysaccharide (LPS) (100 ng/mL).

A fast clustering algorithm for data with a few labeled instances.

The diameter of a cluster is the maximum intracluster distance between pairs of instances within the same cluster, and the split of a cluster is the minimum distance between instances within the cluster and instances outside the cluster. Given a few labeled instances, this paper includes two aspects. First, we present a simple and fast clustering algorithm with the following property: if the ratio of the minimum split to the maximum diameter (RSD) of the optimal solution is greater than one, the algorithm returns optimal solutions for three clustering criteria.
