Therapeutic effect of low-dose BMSCs-Loaded 3D microscaffold on early osteonecrosis of the femoral head.

The early treatment of Osteonecrosis of Femoral Head (ONFH) remains a clinical challenge. Conventional Bone Marrow Mesenchymal Stem Cell (BMSC) injection methods often result in unsatisfactory outcomes due to mechanical cell damage, low cell survival and retention rates, inadequate cell matrix accumulation, and poor intercellular interaction. In this study, we employed a novel cell carrier material termed "3D Microscaffold" to deliver BMSCs, addressing these issues and enhancing the therapeutic effects of cell therapy for ONFH.

Tetrandrine targeting SIRT5 exerts anti-melanoma properties via inducing ROS, ER stress, and blocked autophagy.

Tetrandrine (TET), a natural bisbenzyl isoquinoline alkaloid extracted from S. Moore, has diverse pharmacological effects. However, its effects on melanoma remain unclear.

Sulforaphane alleviates membranous nephropathy by inhibiting oxidative stress-associated podocyte pyroptosis.

Objectives: To investigate the natural product sulforaphane (SFN) in protection of membranous nephropathy (MN) by inhibiting oxidative stress-associated podocyte pyroptosis.

Materials And Methods: A passive Heymann nephritis (PHN) model was established and treated with SFN. Clinical manifestations were examined by testing 24-hr urine protein, albumin, total cholesterol, triglyceride, high-density and low-density lipoprotein levels.

Teriparatide as a non-surgical salvage therapy for prolonged humerus fracture nonunion: A case report and literature review.

Background: Fracture nonunion represents a challenging complication during fracture repair, often necessitating surgical intervention. Teriparatide, a recombinant human parathyroid hormone, has demonstrated promise in enhancing fracture healing, although its efficacy in treating established nonunion remains under investigation.

Case Summary: We report a case of a 27-year-old male who presented with a right humerus fracture following a traffic accident.

Mechanically Triggered Protein Desulfurization.

The technology of native chemical ligation and postligation desulfurization has greatly expanded the scope of modern chemical protein synthesis. Here, we report that ultrasonic energy can trigger robust and clean protein desulfurization, and we developed an ultrasound-induced desulfurization (USID) strategy that is simple to use and generally applicable to peptides and proteins. The USID strategy involves a simple ultrasonic cleaning bath and an easy-to-use and easy-to-remove sonosensitizer, titanium dioxide.
