Proton Beam Therapy for a Rare Anaplastic Pleomorphic Xanthoastrocytoma: Case Report and Literature Review.

Anaplastic pleomorphic xanthoastrocytoma (PXA) is a rare, aggressive WHO grade III tumor that primarily affects children and young adults. Despite surgery being the primary treatment, achieving complete tumor removal is often difficult due to its infiltrative nature, necessitating additional therapies like proton beam therapy (PBT). PBT, known for its precision in targeting tumors while minimizing damage to surrounding healthy tissue, has shown promise in treating malignant gliomas.

Constructing Robust Interfaces in CoSe/Nitrogen-Doped Carbon for Superior Long-Life Sodium-Ion Storage.

Robust interfaces in anodes play a crucial role in boosting sodium-ion battery (SIB) performance. However, the fragile interfaces constructed by a two-step synthesis or artificial stack are prone to be destroyed during the charging/discharging processes, which significantly reduces the lifetime of SIBs. Here, a facile construction strategy is developed to produce robust interfaces in hollow sphere-like CoSe/nitrogen-doped carbon (HS-CoSe/NC) using intrinsic Co, N, C in metal-organic framework as precursors, which enhance the electron/ion diffusion kinetics.

Hesperidin enhanced anti-breast cancer effect and alleviated cisplatin induced nephrotoxicity through silk fibroin delivery system.

The incidence rate and mortality rate of breast cancer remain high, and there is an urgent need for safe and effective drugs. The excellent biological activity of hesperidin (HE) is a potential drug for the treatment of breast cancer. In this study, silk fibroin peptides (SFP) were used as delivery carriers and HE loaded SFP nanofibers (SFP/HE NFs) was prepared.

Effect of polypropylene microplastics on the performance of membrane bioreactors in wastewater treatment.

Membrane bioreactors (MBRs) can effectively remove microplastics (MPs) because of their good rejection performance. However, the influence of MP concentration and particle size on the short-term and long-term operation efficiency of MBRs remains unclear. To address this issue, this study investigated the effects of short-term stress and long-term accumulation of polypropylene microplastics (PP-MPs) with different particle sizes on the operational efficiency of MBRs by running three MBR systems at four concentration stages.

Systematic review and meta-analysis of photon radiotherapy versus proton beam therapy for pediatric intracranial ependymoma: TRP-ependymoma 2024.

However, it is difficult to evaluate whether the actual therapeutic effect is truly equivalent to that of photon radiotherapy. To compare photon radiotherapy and PBT, a meta-analysis and systematic review were performed.

Cholesteric Cellulose Liquid Crystal Fibers by Direct Drawing.

Polymer fibers are attracting increasing attention as a type of fundamental material for a wide range of products. However, to incorporate novel functionality, a crucial challenge is to simultaneously manipulate their structuring across multiple length scales. In this research, a facile and universal approach is proposed by directly drawing a pre-gel feedstock embedding a cellulose cholesteric liquid crystal (CLC).

Ellagic acid ameliorates alcohol-induced cognitive and social dysfunction through the gut microbiota-mediated CCL21-CCR7 axis.

Chronic alcohol consumption disrupts the balance of the gut microbiome, resulting in alcohol-induced cognitive and social dysfunction (AICSD), and serves as a primary etiological factor for early-onset dementia. Ellagic acid (EA) is a polyphenolic compound belonging to the ellagitannin family, showing potential as a dietary intervention for alleviating cognitive impairments. Nonetheless, the protective effects and underlying mechanisms of EA on AICSD remain unclear.

Genetics of Female Pelvic Organ Prolapse: Up to Date.

Pelvic organ prolapse (POP) is a benign disease characterized by the descent of pelvic organs due to weakened pelvic floor muscles and fascial tissues. Primarily affecting elderly women, POP can lead to various urinary and gastrointestinal tract symptoms, significantly impacting their quality of life. The pathogenesis of POP predominantly involves nerve-muscle damage and disorders in the extracellular matrix metabolism within the pelvic floor.

Somatic Mutations in Myometrial Cells.

Over 70% of leiomyoma (LM) harbor mutations, primarily in exon 2 at c.130-131 (GG). Myometrial cells are the cell origin of leiomyoma, but the MED12 mutation status in non-neoplastic myometrial cells is unknown.

Lipid metabolism reprogramming in endometrial cancer: biological functions and therapeutic implications.

Background: Endometrial cancer is one of the major gynecological cancers, with increasing incidence and mortality in the past decades. Emerging preclinical and clinical data have indicated its close association with obesity and dyslipidemia. Metabolism reprogramming has been considered as the hallmark of cancer, to satisfy the extensive need of nutrients and energy for survival and growth.

Platelet indices and the risk of pulmonary arterial hypertension: a two-sample and multivariable Mendelian randomization study.

Background: Recent epidemiological studies have indicated a correlation between platelet indices and pulmonary arterial hypertension (PAH), yet the causality between them remains unclear. To explore the causal relationship between four platelet indices and PAH, with the aim of providing a theoretical basis for clinical prevention and treatment.

Methods: Single-nucleotide polymorphisms (SNPs) associated with platelet-related traits were selected as exposure factors from published genome-wide association studies (GWAS), including: platelet count (PLT), plateletcrit (PCT), mean platelet volume (MPV), and platelet distribution width (PDW).

Toll-Like Receptors Mediate Opposing Dendritic Cell Effects on Treg/Th17 Balance in Mice With Intracerebral Hemorrhage.

Background: Dendritic cells (DCs) regulate the immune response associated with T lymphocytes, but their role in stroke remains unclear. In this study, we investigated the causal relationship between DCs and T-cell response in intracerebral hemorrhage (ICH) by focusing on TLRs (toll-like receptors) that may modulate the function of DCs.

Methods: We studied the effects of TLR4, TLR2, and TLR9 on DC-mediated T-cell response and the outcomes of ICH using male C57BL/6 and CD11c-DTx (diphtheria toxin) receptor mice.

Pan-cancer analysis of the disulfidptosis-related gene and its potential biological function and prognostic significance in gliomas.

Background: Numerous studies have shown a strong correlation between disulfidptosis and various cancers. However, the expression and function of , a crucial gene in disulfidptosis, remain unclear in the context of cancer.

Methods: Gene expression and clinical information on lung adenocarcinoma were obtained from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases.

Late Changes in Renal Volume and Function after Proton Beam Therapy in Pediatric and Adult Patients: Children Show Significant Renal Atrophy but Deterioration of Renal Function Is Minimal in the Long-Term in Both Groups.

To compare late renal effects in pediatric and adult patients with malignancies after PBT involving part of the kidney.
