The crosstalks between vascular endothelial cells, vascular smooth muscle cells, and adventitial fibroblasts in vascular remodeling.

Pathological vascular remodeling (VR) is characterized by structural and functional alterations in the vascular wall resulting from injury, which significantly contribute to the development of cardiovascular diseases (CVDs). The vascular wall consists primarily of endothelial cells (ECs), vascular smooth muscle cells (VSMCs), and adventitial fibroblasts (AFs), whose interactions are crucial for both the formation of the vascular system and the maintenance of mature blood vessels. Disruptions in the communication between these cell types have been implicated in the progression of VR.

Effectiveness of low-load resistance training with blood flow restriction vs. conventional high-intensity resistance training in older people diagnosed with sarcopenia: a randomized controlled trial.

Low-load resistance training with blood flow restriction (LRT-BFR) has shown potential to improve muscle strength and mass in different populations; however, there remains limited evidence in sarcopenic people diagnosed with sarcopenia criteria. This study systematically compared the effectiveness of LRT-BFR and conventional high-intensity resistance training (CRT) on clinical muscle outcomes (muscle mass, strength and performance), cardiovascular disease (CVD) risk factors and sarcopenia-related biomarkers of older people with sarcopenia. Twenty-one older individuals (aged 65 years and older) diagnosed with sarcopenia were randomly assigned to the LRT-BFR (20%-30% one-repetition maximum (1RM), n = 10) or CRT (60%-70% 1RM, n = 11) group.

A clinicopathological and molecular series of five TFEB-altered renal cell carcinoma (RCC) cases: highlighting an aggressive subset of TFEB-rearranged RCC concomitant with TFEB amplification/gene copy number gains.

The classification of TFEB-altered renal cell carcinoma (RCC) has been revised to include TFEB-rearranged RCC and TFEB-amplified RCC in the 2022 World Health Organization (WHO) Classification of Tumors of the Urinary System. Given the wide spectrum of TFEB-altered RCC in terms of morphology and clinical behavior, an accurate diagnosis is challenging yet crucial, particularly in aggressive cases. Moreover, the concurrence of TFEB gene rearrangement and amplification/gene copy number (GCN) gains was also observed, but there was limited knowledge of these cases.

3D printed cell-free bilayer porous scaffold based on alginate with biomimetic microenvironment for osteochondral defect repair.

Despite significant progress in repairing osteochondral injuries using 3D printing technology, most cartilage layer scaffolds are made of degradable materials, making it difficult to simultaneously provide extracellular matrix functionality while replicating the mechanical properties of natural cartilage layers. Additionally, their degradation rate is challenging to align with cartilage regeneration. Furthermore, double-layer scaffolds commonly used for repairing osteochondral often exhibit inadequate bonding between the cartilage layer scaffolds and bone layer scaffolds.

Nanozyme-enhanced injectable hyaluronic acid-based hydrogel for the treatment of osteoarthritis.

The progression of osteoarthritis (OA) is dramatically accelerated by excessive reactive oxygen species (ROS)-induced apoptosis of chondrocytes and the inflammatory response of synovial macrophages. In this study, we developed an injectable hydrogel with a catalase-mimicking nanozyme activity as a therapeutic agent for OA. In vitro experiments confirmed that the HA and peroxide-mimetic nanoenzyme-enhanced hydrogel, containing ε-polylysine/MnCoO (ε-PLE/MnCoO) nanoparticles, continuously eliminated ROS and inflammatory cytokines while promoting the polarization of inflammatory macrophages (M1 phenotype) towards anti-inflammatory macrophages (M2 phenotype) in dysfunctional microenvironments.
