Maintaining the Cartilage Phenotype of Late-Passage Chondrocytes Using Salidroside, TGF-β, and Sulfated Alginate for Cartilage Tissue Engineering Applications.

The limited self-repair capacity of cartilage due to its avascular and aneural nature leads to minimal regenerative ability. Autologous chondrocyte transplantation (ACT) is a popular treatment for cartilage defects but faces challenges due to chondrocyte dedifferentiation in later passages, which results in undesirable fibroblastic phenotypes. A promising treatment for cartilage injuries and diseases involves tissue engineering using cells (e.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Pseudo-Perception: A New Concept for Resolving the Problems of Long Instruments in Neurosurgical Interventions.

Long surgical instruments, particularly in brain endoscopy, often compromise precision and control due to the physical distance between the surgeon's hand and the instrument's tip, increasing the likelihood of tremors. Various technological solutions, including robotics, have been proposed to address this issue. This report outlines the development of a pseudo-perception system aimed at improving control over long instruments in neurosurgical procedures by manipulating visual feedback to enhance the surgeon's sense of proximity to the instrument's tip.

The flute: A new microsurgical instrument performing the work of three instruments simultaneously.

Background: The surgical suction, irrigator, and retractor are vital instruments in all operative neurosurgical interventions. Several trials previously tried to combine these instruments to reduce the number of working hands in the surgical field and make them more controllable by the surgeon. An instrument combined the suction and irrigation used, and others added suction with the dissector, which was also invented but with many drawbacks.

Efficacy of Autologous Platelet-Rich Plasma Injections for Treating Plantar Fasciitis.

Introduction Plantar fasciitis, a common cause of heel pain, is often treated conservatively. Platelet-rich plasma (PRP) injections have emerged as a promising treatment option. This study aimed to evaluate the efficacy of autologous PRP injections for plantar fasciitis.
