A soft, ultra-tough and multifunctional artificial muscle for volumetric muscle loss treatment.

The escalating prevalence of skeletal muscle disorders highlights the critical need for innovative treatments for severe injuries such as volumetric muscle loss. Traditional treatments, such as autologous transplants, are constrained by limited availability and current scaffolds often fail to meet complex clinical needs. This study introduces a new approach to volumetric muscle loss treatment by using a shape-memory polymer (SMP) based on block copolymers of perfluoropolyether and polycaprolactone diol.

A novel allosteric driver mutation of β-glucuronidase promotes head and neck squamous cell carcinoma progression through STT3B-mediated PD-L1 N-glycosylation.

Head and neck squamous cell carcinoma (HNSCC) develops and advances because of the accumulation of somatic mutations located in orthosteric and allosteric areas. However, the biological effects of allosteric driver mutations during tumorigenesis are mostly unknown. Here, we mapped somatic mutations generated from 10 tumor-normal matched HNSCC samples into allosteric sites to prioritize the mutated allosteric proteins via whole-exome sequencing and AlloDriver, identifying the specific mutation H351Q in β-glucuronidase (GUSB), a lysosomal enzyme, as a novel allosteric driver mutation, which considerably encouraged HNSCC progression both in vitro and in vivo.

Transcriptional regulation of Rankl by Txnip-Ecd in aging and diabetic related osteoporosis.

Introduction: Bone homeostasis between osteoclast bone resorption and osteoblastic bone formation is tightly regulated by a series of factors such as the receptor activator of nuclear factor-κB ligand (RANKL). Denosumab that neutralizes RANKL is effective and widely applied in the treatment of postmenopausal osteoporosis. However, factors that participated in the RANKL-related bone remodeling process in primary and secondary osteoporosis are less known.

Multiscale Engineered Bionic Solid-State Electrolytes Breaking the Stiffness-Damping Trade-Off.

All-solid-state lithium metal batteries are regarded as next-generation devices for energy storage due to their safety and high energy density. The issues of lithium dendrites and poor mechanical compatibility with electrodes present the need for developing solid-state electrolytes with high stiffness and damping, but it is a contradictory relationship. Here, inspired by the superstructure of tooth enamel, we develop a composite solid-state electrolyte composed of amorphous ceramic nanotube arrays intertwined with solid polymer electrolytes.

Inflammatory adhesion mediates myocardial segmental necroptosis induced by mixed lineage kinase domain-like protein in acute myocardial infarction.

Purpose: Cardiomyocyte death is a major cytopathologic response in acute myocardial infarction (AMI) and involves complex inflammatory interactions. Although existing reports indicating that mixed lineage kinase domain-like protein (MLKL) is involved in macrophage necroptosis and inflammasome activation, the downstream mechanism of MLKL in necroptosis remain poorly characterized in AMI.

Methods: MLKL knockout mice (MLKL), RIPK3 knockout mice (RIPK3), and macrophage-specific MLKL conditional knockout mice (MLKL) were established.

Integrins identified as potential prognostic markers in osteosarcoma through multi-omics and multi-dataset analysis.

Osteosarcoma represents 20% of primary malignant bone tumors globally. Assessing its prognosis is challenging due to the complex roles of integrins in tumor development and metastasis. This study utilized 209,268 osteosarcoma cells from the GEO database to identify integrin-associated genes using advanced analysis methods.

In this study, whole exome sequencing (WES) and genetic linkage analysis across a four-generation lineage presenting with six cases of FPD are conducted.

Bacteria in hypertrophic scars promote scar formation through HSBP1-mediated autophagy.

Bacterial colonisation in hypertrophic scars (HSs) has been reported, yet the precise mechanism of their contribution to scar formation remains elusive. To address this, we examined HS and normal skin (NS) tissues through Gram staining and immunofluorescence. We co-cultured fibroblasts with heat-inactivated Staphylococcus aureus (S.

Autologous Micro-Fat Transplantation for Facial Sunken Treatment: Single-Center Experience.

Background: Facial sunken deformities, congenital or acquired, are common in clinical practice for the reduction of soft or hard tissues. In clinical practice, filler injection and tissue transplantation are often used to improve facial contour. Among these, autologous fat grafting for treating facial contour defects is most common in clinical practice.

The impact of long-term prescription policy on primary care utilisation and costs among hypertensive patients in China: a six-year longitudinal study.

Background: China has recently implemented a long-term prescription policy as a component of the family doctor system in order to strengthen chronic disease management. In this study, we evaluated the net policy impact on health care utilisation and costs at community health centres (CHCs) among hypertensive patients.

Methods: The study population included 164 857 hypertensive patients from a provincial capital city in Eastern China, with an average age of 69.

Histological and Molecular Manifestations of Cleft Myopathy.

Objective: Apart from rupture and displacement of muscle fibers, structural defects exist in cleft muscles but have not been adequately investigated. This study aimed to examine the histological and molecular features of the cleft muscles.

Design: Orbicularis oris (OO) and tensor fasciae latae (TFL) muscle samples were obtained from patients with cleft lip and alveolar.

Association between circulating inflammatory proteins and temporomandibular disorders: insight from a two-sample Mendelian randomization analysis.

Background: Past studies have indicated links between specific inflammatory proteins in the bloodstream and temporomandibular disorders (TMDs). Nonetheless, there remains the need for further solid research pinpointing the exact causes behind these associations. This Mendelian randomization (MR) study aims to examine the association between 91 circulating inflammatory proteins and TMDs.

Middle-aged obesity, characterized by excessive fat accumulation and systemic energy imbalance, often precedes various health complications. Recent research has unveiled a surprising link between DNA damage response and energy metabolism. Here, we explore the role of Eepd1, a DNA repair enzyme, in regulating adipose tissue function and obesity onset.

Sialoblastomas With Solid Pattern Have FGFR2 Mutations and an Unfavorable Prognosis.

Although sialoblastoma (SBL) is defined as a low-grade malignant salivary gland anlage neoplasm in the 2022 World Health Organization (WHO) Classification of Head and Neck Tumors, its histology, genetics, and behavior remain controversial due to the rarity of the tumor. Here, we performed the first comprehensive clinical, histologic, and molecular analyses of 8 SBLs to better understand their pathogenesis and prognosis. This cohort consisted of 5 boys and 3 girls, with ages ranging from birth to 9 years at diagnosis.

Identification of USP2 as a novel target to induce degradation of KRAS in myeloma cells.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity.

Construction and evaluation of a multifactorial clinical model for discriminating benign and malignant breast tumors using LASSO algorithm based on retrospective cohort study.

Breast cancer is one of the malignant tumors that seriously threaten women's health, and early diagnosis and detection of breast cancer are crucial for effective treatment. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is an important diagnostic tool that allows for the dynamic observation of blood flow characteristics of breast tumors, including small lesions within the affected tissue. Currently, it is widely used in clinical practice and has been shown promising prospects.
