Mesoporous Silica-Carbon Composites with Enhanced Conductivity: Analysis of Powder and Thin Film Forms.

The resistivity of the silica SBA-15 type can be significantly improved by forming a thin layer of carbon on the pore surface. This is possible through the carbonization reaction of a surfactant used as a structure-directing agent in the synthesis of mesostructured silica materials. The synthesis of this type of silica-carbon composite (SBA-C) is based on the use of sulfuric acid to create a carbon layer from surfactant molecules encapsulated in silica mesopores.

YouTube as a Source of Patient Information for Cervical Spine Fractures: A Content Quality and Audience Engagement Analysis.

This study aimed to assess the quality of YouTube (YT) videos providing medical information on cervical spine fractures; secondly, a comparison of two timeframes has been conducted. Using Google Chrome with privacy settings to minimize personalization, two searches were conducted on 20 July 2021 and the second one on 10 April 2024 using various terms related to cervical spine injuries. Videos were evaluated using the DISCERN (Quality Criteria for Consumer Health Information), GQS (Global Quality Score), and JAMA scoring systems.

Effects of experimental nest treatment with herbs on ectoparasites and body condition of nestlings.

Nest fumigation behavior involves the incorporation of fresh green plant fragments that contain ectoparasite-repellent volatile compounds into birds' nests. This behavior is relatively rare among bird species, and there is ongoing debate about whether it benefits parental breeding success. In this study, we experimentally tested whether the inclusion of aromatic-herbal plant fragments in the nests of great tits affects the physiological condition of nestlings, as indicated by blood levels of hematocrit, hemoglobin, glucose, and body condition indices, such as weight and wing length.

Diffuse large B-cell lymphoma mimicking the cervical epidural hematoma in a patient who underwent spinal manipulation therapy: a case report and literature review.

The diffuse large B-cell lymphoma (DLBCL) mimicking an epidural hematoma in the cervical spine is an extremely unique case. We present a case of a 42-year-old man, who presented to the emergency department with symptoms of tetraparesis after a session of spinal manipulation therapy. magnetic resonance imaging visualized a lesion located at C3-C7 causing spinal cord compression with surrounding soft tissue edema suggesting epidural hematoma.

Synthesis of spherical and rods-like titanium oxide nanoparticles (TiO NPs) and evaluation of their cytotoxicity towards colon cells in vitro.

Titanium oxide nanoparticles (TiO NPs) are currently used as ingredients in medicines and sunscreens. Unfortunately, recent information about TiO NPs indicates their undesirable biological effect on colon cells. Therefore, the aim of this work was to synthesize and evaluate the physicochemical characterization of spherical (TiO NSs) and rods-like (TiO NRs) NPs, followed by assessment their cytotoxicity.
