Wessely-type immune ring following collagen cross-linking.

A woman in her early 20s with progressive keratoconus underwent corneal collagen cross-linking using the sub400 protocol. The central 5.5 mm of the epithelium was removed after the application of 20% alcohol.

Effects of maturity status on the rate of torque development in young male soccer players.

Background: The rate of torque development (RTD) has been associated with sports performance and can be improved during the biological maturation process of young soccer players. The aim of this study was to compare the effects of maturity status on the knee extensors' RTD of soccer players after appropriate normalization.

Methods: Twenty-seven young male soccer players aged 13-18 years old were allocated into two groups: pubescent (PUB, n = 11) and postpubescent (POSP, n = 16).

Amputations Resulting From Systemic Sclerosis: The Role of Multidisciplinary Cooperation.

Systemic sclerosis (SSc) is a complex connective tissue disease involving microvasculopathy, immune dysregulation, and extensive organ fibrosis. It affects various systems including the skin, lungs, heart, and gastrointestinal tract. Management is challenging due to the disease's heterogeneity and often requires more than just pharmacological treatment.

Mechanical and Corrosion Behaviour in Simulated Body Fluid of As-Fabricated 3D Porous L-PBF 316L Stainless Steel Structures for Biomedical Implants.

Laser powder bed fusion (L-PBF) is one of the most promising additive manufacturing technologies for creating customised 316L Stainless Steel (SS) implants with biomimetic characteristics, controlled porosity, and optimal structural and functional properties. However, the behaviour of as-fabricated 3D 316L SS structures without any surface finishing in environments that simulate body fluids remains largely unknown. To address this knowledge gap, the present study investigates the surface characteristics, the internal porosity, the corrosion in simulated body fluid (SBF), and the mechanical properties of as-fabricated 316L SS structures manufactured by L-PBF with rhombitruncated cuboctahedron (RTCO) unit cells with two distinct relative densities (10 and 35%).
