A workflow to assess the recoverability of secondary raw materials via physical separation.

Printed circuit boards represent an extraordinarily challenging fraction for the recycling of waste electric and electronic equipment. Due to the closely interlinked structure of the composing materials, the selective recycling of copper and closely associated precious metals from this composite material is compromised by losses during mechanical pre-processing. This problem could partially be overcome by a better understanding of the influence of particle size and shape on the recovery of finely comminuted and well-liberated metal particles during mechanical separation.

SARS-CoV-2 strains and clinical profiles of COVID-19 patients in a Southern Brazil hospital.

Introduction: The COVID-19 pandemic had a widespread global impact and presented numerous challenges. The emergence of SARS-CoV-2 variants has changed transmission rates and immune evasion, possibly impacting the severity. This study aims to investigate the impact of variants on clinical outcomes in southern Brazil.

Clinicopathological comparison and cytokeratin-10 expression between Lichen planus and oral lichenoid lesions.

Objectives: This study aimed to compare clinicopathological features and immunostaining for cytokeratin-10 between oral lichen planus and oral lichenoid lesions.

Design: This was a retrospective longitudinal study comparing lichen planus and oral lichenoid lesions diagnosed at the Oral Pathological Anatomy Service that analyzed sociodemographic and clinicopathological data and CK10 expression. Chi-square tests, Fisher's exact tests and Mann-Whitney tests or Student's t tests were used when appropriate, and p values < 0.

Orofacial pain models induce impairment in spatial learning and working memory in rodents: A systematic review and meta-analysis.

Orofacial pain is one of the most common causes of chronic pain leading to physical and cognitive disability. Several clinical and pre-clinical studies suggest that chronic pain results in cognitive impairment. However, there is a lack of meta-analyses examining the effects of orofacial pain models on behavioral learning and memory in rodents.

Regulatory Role of Vacuolar Calcium Transport Proteins in Growth, Calcium Signaling, and Cellulase Production in .

Recent research has revealed the calcium signaling significance in the production of cellulases in . While vacuoles serve as the primary calcium storage within cells, the function of vacuolar calcium transporter proteins in this process remains unclear. In this study, we conducted a functional characterization of four vacuolar calcium transport proteins in .
