Diagnostic Utility of Nailfold Capillaroscopy using Hand-held Dermoscope in Systemic Sclerosis.

Introduction: The pathogenesis in systemic sclerosis (SSc) mainly involves vascular injury, fibrosis, and immune activation. Visualization of these microvascular changes by nailfold capillaroscopy (NFC) can help in the early diagnosis of the disease. Even though the gold standard for NFC is a videodermoscope, the ease, practicality, and accessibility make the hand-held dermoscope a more versatile and suitable device in the hands of the dermatologists in the busy outpatient department.

Effect of Low-Temperature Plasma Treatment on Starch-Based Biochar and Its Reinforcement for Three-Dimensional Printed Polypropylene Biocomposites.

Uniform dispersion and high interfacial adhesion are two of the most difficult components of creating an ideally reinforced polymer composite. One of the solutions could be surface engineering of reinforcing filler materials utilizing innovative technologies. Low-temperature plasma treatments in the presence of sulfur hexafluoride (SF6) gas are proposed as a sustainable alternative to modify the surface properties of biochar carbon synthesized from sustainable starch-based packaging waste via a high-temperature/pressure pyrolysis reaction in the current study.
