Structural, Optical, Surface, and Gas-Sensing Properties of rGO/Sn1–xZnxO₂ Nanocomposites
Abstract: rGO/Sn₁–ₓZnₓO₂ nanocomposites with x = 0.00–0.75 were synthesized by sol–gel auto-combustion followed by wet impregnation with reduced graphene oxide. The adopted synthesis route enabled homogeneous Zn incorporation into the SnO₂ matrix and uniform distribution of rGO, leading to improved structural integrity and interfacial contact between the two components. XRD confirmed a dominant tetragonal cassiterite SnO₂ structure, while FTIR, FESEM, EDS, UV–visible, and BET analyses verified oxide–rGO coupling, Zn-dependent structural modification, …

A Short Review on Long-Term Effects of Botox on Neuronal Sprouting: Mechanisms and Its Clinical Implications
Abstract: Botulinum toxin (Botox) is extensively used for its ability to induce temporary muscle paralysis through inhibition of acetylcholine release at neuromuscular junctions. While its short-term effects are well documented, emerging evidence suggests that chronic use of Botox may trigger neuronal sprouting, a process that could have significant long-term implications. This review synthesizes current research on the mechanisms by which Botox induces nerve sprouting and evaluates the clinical outcomes associated with …

Thrombotic thrombocytopenic purpura: A Narrative Review of Diagnosis and Treatment by drugs and novel agents.
Abstract: Thrombotic thrombocytopenic purpura (TTP) is an infrequent but fatal disease, is primarily caused by autoantibodies against the von Willebrand factor (VWF) cleaving metalloprotease ADAMTS13. Overall, severe deficiency of plasma ADAMTS13 action (< 10 IU dL-1) with or without noticeable inhibitory autoantibodies counter to ADAMTS13 supports the diagnosis of TTP. The International Working Group for TTP released a consensus statement on the standardization of terminology in these disorders which we use …
