Peritoneal dialysis (PD) is limited by glucose-mediated peritoneal membrane (PM) fibrosis, angiogenesis, and ultrafiltration failure. Influencing PM integrity pharmacologically targeting sodium-dependent glucose transporter (SGLT)-mediated uptake has not been studied. In this study, wildtype C57Bl/6N mice were treated with high-glucose dialysate via an intraperitoneal catheter, or without addition of selective SGLT2 inhibitor dapagliflozin. structural changes, capacity, equilibration testing...

Abstract Bone infections are a frequent cause for large bony defects with reduced healing capacity. In previous findings, we could already show diminished capacity after bone infections, despite the absence of causing agent, Staphylococcus aureus. Moreover, these showed osteoblastogenesis and increased osteoclastogenesis, meaning elevated resorption ongoing an B-cell activity. To overcome negative effects this postinfectious inflammatory state, tried to use regenerative mesenchymal stem...

Acute ischemia reperfusion injury in skeletal muscle remains an important issue several fields of regenerative medicine. Thus, a valid model is essential to gain deeper insights into pathophysiological relations and evaluate possible treatment options. While the vascular anatomy mice regularly prevents sufficient vessel occlusion by invasive methods, there multitude existing models induce without surgical procedures. Since no consensus on which prefer, this study aims develop novel,...

<b><i>Background:</i></b> Burn injury leads to a hypercatabolic response and ultimately muscle wasting with drastic implications for recovery of bodily functions, patient’s quality life (QoL), long-term survival. Several treatment options target the body’s initial stress response, but pharmacological approaches specifically address protein metabolism have only been poorly investigated. <b><i>Objective:</i></b> The aim this study was assess role...

Abstract Impaired bone homeostasis caused by osteomyelitis provokes serious variations in the remodeling process, thereby involving multiple inflammatory cytokines to activate healing. We have previously established a mouse model for post-traumatic and studied regeneration after sufficient debridement. Moreover, we could further characterize postinfectious state of bony defects debridement with elevated osteoclasts decreased formation despite absence bacteria. In this study, investigated...

Abstract Ischemia reperfusion (IR) injury plays a pivotal role in many diseases and leads to collateral damage during surgical interventions. While most studies focus on alleviating its severity the context of brain, liver, kidney, cardiac tissue, research as regards skeletal muscle has not been conducted same extent. In past, myostatin (MSTN), primarily known for supressing growth, implicated inflammatory circuits, provided promising results IR mitigation by inhibiting MSTN cell surface...

Tumors, traumata, burn injuries or surgeries can lead to critical-sized bony defects which need be reconstructed. Mesenchymal stem cells (MSCs) have the ability differentiate into multiple cell lineages and thus present a promising alternative for use in tissue engineering reconstruction. However, there is an ongoing debate whether all MSCs are equivalent their differentiation proliferation ability. The goal of this study was assess osteogenic adipogenic characteristic changes...
