Surgical management of an extensive nasal mass in an adolescent: insights from diagnostic imaging and histopathology.

A 17-year-old female presented with a mass in the right nasal fossa and eye protrusion. Imaging revealed a large osseous mass originating from the right turbinates, causing exophthalmos without tissue invasion. A partial resection via the Caldwell-Luc approach was performed, but hemodynamic instability halted the procedure, leaving a residual mass.

Venom composition, toxicity and cross-neutralization by PoliVal-ICP antivenom, of Mesoamerican jumping pitvipers genus Metlapilcoatlus (Viperidae: Crotalinae).

Background: The genus Metlapilcoatlus was recently erected to include six species of stout venomous snakes, known as the jumping pitvipers, which inhabit mountainous areas of Mesoamerica. This group maintains affinity with Atropoides picadoi, another jumping pitviper with restricted distribution in Costa Rica and Panama. Although the venom of A.

Jumping Dynamics of Cyanomethyl Radicals on Corrugated Graphene/Ru(0001) Substrates.

Graphene adsorbed on Ru(0001) has been widely used as a template for adsorbing and isolating molecules, assembling organic-molecule structures with desired geometric and electronic properties and even inducing chemical reactions that are challenging to achieve in the gas phase. To fully exploit the potential of this substrate, for example, by being able to tune a graphene-based catalyst to perform optimally under specific conditions, it is crucial to understand the factors and mechanisms governing the molecule-substrate interaction. To contribute to this effort, we have conducted a combined experimental and theoretical study of the adsorption of cyanomethyl radicals (-CHCN) on this substrate below room temperature by performing scanning tunneling microscopy experiments and density functional theory simulations.

Performance of the VITEK® MS system for the identification of filamentous fungi in a microbiological laboratory in Chile.

Filamentous fungi are an emergent cause of severe infections in immunocompromised patients. Timely and accurate identification is crucial to initiate appropriate therapy. Traditional identification methods are time-consuming, labor-intensive, and operator-dependent.
