Essential oil of the leaves of L.: chemical composition, antioxidant, anti-inflammatory, and cytotoxic properties.

This study is focused on investigating the chemical composition and bioactive properties of the essential oil extracted from L., a plant species known for its medicinal properties. Utilising gas chromatography-mass spectrometry (GC-MS) analysis, the essential oil from was found to contain 53 distinct constituents.

Polythiophene-wrapped Chitosan Nanofibrils with a Bouligand Structure toward Electrochemical Macroscopic Membranes.

Exploring structural biomimicry is a great opportunity to replicate hierarchical frameworks inspired by nature in advanced functional materials for boosting new applications. In this work, we present the biomimetic integration of polythiophene into chitosan nanofibrils in a twisted Bouligand structure to afford free-standing macroscopic composite membranes with electrochemical functionality. By considering the integrity of the Bouligand structure in crab shells, we can produce large, free-standing chitosan nanofibril membranes with iridescent colors and flexible toughness.

Assistance from Automated ASPECTS Software Improves Reader Performance.

Purpose: To compare physicians' ability to read Alberta Stroke Program Early CT Score (ASPECTS) in patients with a large vessel occlusion within 6 hours of symptom onset when assisted by a machine learning-based automatic software tool, compared with their unassisted score.

Materials And Methods: 50 baseline CT scans selected from two prior studies (CRISP and GAMES-RP) were read by 3 experienced neuroradiologists who were provided access to a follow-up MRI. The average ASPECT score of these reads was used as the reference standard.

Radiation therapy and PD-1/PD-L1 blockade: the clinical development of an evolving anticancer combination.

Several inhibitors of programmed cell death-1 (PD-1) and programmed death ligand-1 (PD-L1) have been approved as a form of immunotherapy for multiple cancers. Ionizing radiation therapy (RT) has been shown to enhance the priming and effector phases of the antitumor T-cell response rendering it an attractive therapy to combine with PD-1/PD-L1 inhibitors. Preclinical data support the rational combination of the 2 modalities and has paved way for the clinical development of the combination across a spectrum of cancers.

Radiologists Are Actually Well Positioned to Innovate in Patient Experience.

Patient experience is becoming increasingly prioritized, most notably as a component of recently passed health care legislation that aims to link physician reimbursement to quality of care and cost-effectiveness. For several reasons, radiologists are better positioned to seize opportunities to enhance patient experience than is readily apparent. We propose that discrete components along the imaging value chain can be evaluated specifically for their effect on patient experience and improved to this end.

Water-soluble chitosan-derived sustainable materials: towards filaments, aerogels, microspheres, and plastics.

Bioinspired materials have aroused great interest as their inherent biocompatible and structural characteristics have given rise to sustainable applications. In this work, we have reported the phase and morphology transformation of chitosan from crystalline nanofibrils into amorphous sheets for fabricating sustainable materials. Acetylation-induced aqueous dissolution of native chitosan nanofibrils affords water-soluble chitosan as a biopolymeric liquid.

Improving Access to Image-guided Procedures at an Integrated Rural Critical Access Hospital: Ultrasound-guided Thyroid Biopsy Program.

Purpose: Critical access hospitals face difficulty providing all services locally and may need to refer patients off-site for additional care. Providing on-site minimally invasive biopsies, may obviate visits to tertiary or quaternary care centers. This study aims to assess feasibility and outcomes of an ultrasound-guided thyroid biopsy program in a critical access hospital.

Left Colonic Bleeding Secondary to Inferior Mesenteric Vein Stenosis.

Lower gastrointestinal bleeding is most commonly associated with diverticulosis, ischemic colitis, vascular ectasia, and anorectal disease and less commonly associated with colonic malignancy. Infrequently, it is associated with mesenteric varices, a rare etiology that is not well documented in the radiology literature. We present a case of a 50-year-old man diagnosed as having intermittent left colonic bleeding from mesenteric varices due to a critical stenosis at the portal vein-inferior mesenteric vein confluence.

MR angiography can guide ED management of suspected acute aortic dissection.

Background: Aortic dissection is typically evaluated with computed tomography angiography (CTA). However, the feasibility of using magnetic resonance angiography (MRA) in the ED is unclear. This study examined the indications and outcomes of MRA in suspected aortic dissection evaluation in the ED.

Incidental findings and recommendations are common on ED CT angiography to evaluate for aortic dissection.

Purpose: The aim of this study was to assess the outcomes, incidental findings, recommendations, and adherence to recommendations on computed tomography angiography (CTA) studies obtained in the emergency department (ED) to evaluate for aortic dissection.

Methods: The institutional database of ED patients was retrospectively reviewed to identify CTA examinations for dissection during 2014. The radiology report and electronic medical records were reviewed to assess outcomes, radiology report incidental findings, and recommendations, as well as adherence to these recommendations.
