#1
Huijun Li, Yu Jun Tan, Kah Fai Leong, Lin Li
A robust alginate/methylcellulose (Alg/MC) blend hydrogel, with a strategy to improve adhesion between printed layers, has been fabricated for the first time for 3D bioprinting. The optimized Alg/MC blend hydrogel exhibits highly thixotropic property, great extrudability and stackability. With treatment by a trisodium citrate (TSC) solution, the interfacial bonding between printed layers is significantly improved. The TSC solution acts as a chelating agent to remove the superficial calcium ions at each layer...

BACKGROUND: In situ pinning of slipped capital femoral epiphysis (SCFE) results in various degrees of deformity of the femoral head-neck junction. Repetitive trauma from cam-type femoroacetabular impingement (FAI) can lead to labral tears and injury to the articular cartilage causing loss of function. Arthroscopic osteoplasty is an alternative to open procedure and to Southwick/Imhäuser-type osteotomies in symptomatic selected cases. SURGICAL TECHNIQUE: The amount of bone to be resected has to be carefully planned pre-operatively...

BACKGROUND: Management of moderately displaced slipped capital femoral epiphysis (SCFE) is debated, mostly because of the risks related to open reduction on one hand, and subsequent evolution toward femoroacetabular impingement (FAI) on the other. METHOD: All SCFE cases treated with in situ fixation (ISF) and a minimum of ten years of follow-up beyond skeletal maturity were analysed in a retrospective multicentre study. Coxometry parameters were measured. Long-term results of ISF were meanwhile analysed at our Institution...

Polycystic ovary syndrome (PCOS) affects up to 18% of reproductive-aged women with reproductive and metabolic complications. While lipidomics can identify associations between lipid species and metabolic diseases, no research has examined the association of lipid species with the pathophysiological features of PCOS. The aim of this study was to examine the lipidomic profile in women with and without PCOS. This study was a cross-sectional study in 156 age-matched pre-menopausal women (18-45 years, BMI>25 kg/m2; n=92 with PCOS, n=64 without PCOS)...
