Development of smart films based on soy protein and cow horn dissolved in a deep eutectic solvent: Physicochemical and environmental assessment.

With the urge to reduce the use of petroleum-based materials, the aim of this work is to valorize biowaste to develop smart films through a sustainable fabrication way. In this regard, choline chloride/urea (1:2) deep eutectic solvent (DES) at different concentrations (25, 40, 50 and 75 wt%) was used to dissolve cow horn, used as reinforcement agent in soy protein films. The film fabrication was carried out by compression molding, a fast and cost-effective.

MultiShapeC, an algorithm to assess concentration in multi-shape nanoparticle samples: nanosilver, a case study.

Shape, size, and dispersity play a crucial role in the calculation of colloidal nanoparticle concentrations, which results in remarkable differences in the determination of parameters like Stern-Volmer constants. In this work, we propose an algorithm named MultiShapeC to include the variability in shapes and polydispersity in the concentration calculation. This algorithm was validated using the quenching of carbazole fluorescence emission by silver nanoparticles.

Case report: Thrombus in transit-a cause of impending paradoxical embolism.

Background: A thrombus in transit (TIT) is a life-threatening condition associated with pulmonary embolism (PE). While TIT was once considered a rare diagnosis, its emergence has risen in recent years mainly through advancement in medical technology. Rare cases of a thrombus in transit crossing a patent foramen ovale in the context of pulmonary embolism have been reported.

Successful initial experience with a novel outpatient total hip arthroplasty program in a public health system in Chile.

Purpose: The aim of the present study was to assess the first experience with outpatient total hip arthroplasty (THA) in a public health environment in Chile.

Methods: Prospective series of the first 69 patients/72 hips. Surgery was performed in a public university-affiliated hospital.

Dermatitis artefacta?

A 35-year-old man presented with a 2-month history of intensely pruritic excoriated and crusted linear lesions on the dorsa of the left hand and left forearm (Fig 1). The patient had worked in construction for 2 years, and his job consisted mainly in covering the facades of buildings with cement. The patient was right-handed and used a black rubber glove as a protective measure only on his left hand (Fig 2).
