Single layer graphene (SLG) was synthesized via high-quality chemical vapor deposition (CVD) on high-quality copper and subsequently transferred onto SiO2 and on n-GaAs substrates with varying doping electron concentrations (n = 1016, 1017, 5 × 1017, 1018, and 5 × 1018 cm-3). The n-GaAs substrates were grown by molecular beam epitaxy. The optical properties of the SLG were investigated through photoluminescence (PL) and Raman spectroscopy measurements.

Aim: To describe the periocular clinical findings in a patient diagnosed with AAPOX, treated successfully by intralesional corticosteroids.
Case Report: A 40-year-old woman presented with bilateral eyelid swelling and adult-onset asthma.
Introduction And Importance: Quadriceps palsy is a sign of femoral nerve injury. Classically it is a compression of the nerve by a haematoma of the iliopsoas muscle in haemophiliacs and patients on anticoagulants. Could this haematoma form after a trauma in a healthy athlete?
Case Presentation: We report a case of 16-year-old kickboxer with no previous history who had been complaining of the left groin for 3 weeks after being struck in the left iliac fossa.
Background: This cross-sectional study aimed to describe and discuss the epidemiology of mucopolysaccharidoses (MPS) in Tunisia.
Methods: Patients diagnosed with a MPS disorder in two referral laboratories in Tunisia between 1999 and 2021 were included. Diagnosis was based on clinical and radiological features and analysis of urinary glycosaminoglycans, and enzyme assay in some of the patients.
