INTRA-ARTICULAR INJECTION OF HYALURONIC ACID AFTER ARTHROSCOPIC SURGERY FAILS TO PROVIDE ADDITIONAL BENEFIT FOR SYMPTOMATIC DEGENERATIVE ARTHROPATHY PATIENTS: A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMIZED CONTROLLED TRIALS

Knee arthroscopy is the replacement choice for patients with symptomatic degenerative arthropathy who have failed conservative treatment, such as intra-articular loose bodies and meniscal pathology.Postoperative joint pain and swelling are the main problems affecting enhanced recovery after surgery, which is thought to be a disorder of the joint en

Designing of new alloys requires a detailed understanding of the roles played by each alloying element, yet a systematic investigation of the solid-solution strengthening effects in Ni is still missing.High throughput density functional theory calculations were therefore performed to quantitatively assess the strengthening effects of 35 potential a

Tetrazolium salts are widely used in biology as indicators of metabolic activity - hence termed vital dyes - but their reduction site is still debated despite decades of intensive research.The prototype, 2,3,5- triphenyl tetrazolium chloride, which was first synthesized a century ago, often generates a single formazan granule at the old pole of Esc

Ethology (the study of animal behaviour) offers useful insights for better understanding how musical sounds evoke emotions in listeners.Modern ethological research has fused semiotic concepts like signals E-Cigs and indices with evolutionary theory.The concepts are illustrated using empirical research on sadness, grief, smiling, pouting, cuteness,

In this paper, robust control strategies are explored to solve the problem of rendezvous maneuver for rigid spacecraft exposed to the external disturbance, actuator faults and unknown inertial parameters.To pursue the control objective, two adaptive controllers are constructed via the sliding mode control (SMC) technology.Firstly, a basic control s
