Two-body wear test of enamel against laboratory polished and clinically adjusted zirconia.

CONCLUSION: Within the constraints of the test method in this experiment, zirconia irrespective of surface preparation, was found to cause less vertical and volumetric enamel wear compared to control enamel. No statistically significant difference was seen between LP zirconia and LP + CA zirconia. PMID: 32469712 [PubMed - as supplied by publisher]

ConclusionsAll fit parameters were in an acceptable range. No differences in fit between Planmeca models suggest no effect of spindle number on accuracy. The detailed setting has no improvement in the marginal or internal fit of the restoration, yet it increases milling time.

Magnetic resonance spectroscopy (MRS) is a non-invasive neuroimaging technique used to investigate in vivo brain metabolites. MRS could provide a sensitive tool for the study of hereditary spastic paraplegia (HSP) by helping to unveil the underlying biochemical mechanisms and monitoring response to treatment. This focused systematic review aimed to summarize the brain metabolite findings in studies performed in genetically determined HSP. The second aim was to provide a critical analysis and recommendations for well-designed protocols for future studies. Fourteen MRS studies have been analyzed with overall 61 HSP patients,...

ConclusionsDetermining whether peritoneal carcinoma is serous carcinoma is important for therapy and prognostic prediction. In this case, we encountered a patient for whom surgery was chosen because of drug therapy resistance inferred through histological type estimation using the cell block method. Inferring the histological type by cell block preparation is useful for diagnosis and treatment selection.

AbstractDante places the sinners who promoted scandals, schism, and discord in the ninth Ditch of the Inferno. Among those is also the Prophet Muhammad. Describing the Prophet ’s punishment, Dante resorts to technical terms and vulgar expressions. This poetic representation highlights Dante’s medical and anatomical knowledge and reflects 14th c. Christian religious beliefs. At that time, autopsies were performed only on prisoners, prostitutes and people without identi ty. By comparing the Prophet to an autopsied corpse, Dante associates Muhammad with those bearing the badge of shame. Moreover, this description ...

Authors: Jiang ZZ, He C, Wang DQ, Shen HL, Sun JL, Gan WN, Lu JY, Liu XT Abstract In December 2019, an outbreak of coronavirus infection emerged in Wuhan, Hubei Province of China, which is now named Coronavirus Disease 2019 (COVID-19). The outbreak spread rapidly within mainland China and globally. This paper reviews the different imaging modalities used in the diagnosis and treatment process of COVID-19, such as chest radiography, computerized tomography (CT) scan, ultrasound examination, and positron emission tomography (PET/CT) scan. A chest radiograph is not recommended as a first-line imaging modality for COVI...
