Abstract Aims Since December 2019, the novel coronavirus SARS‐CoV‐2 has spread rapidly throughout China and keeps world in suspense. Cardiovascular complications with myocarditis embolism due to COVID‐19 have been reported. genome detection heart muscle not demonstrated so far, underlying pathophysiological mechanisms remain be investigated. Methods results Endomyocardial biopsies (EMBs) of 104 patients (mean age: 57.90 ± 16.37 years; left ventricular ejection fraction: 33.7 14.6%, sex: n =...
Abstract Basing on histomorphological evaluations and morphometrical quantifications in a standardized model experiment, comparison is made between the reactions of skeletal tissues to various glasses, glassceramics enamels. On surface these so‐called reactive biomaterials either direct bonding mineralized bone or also different amounts osteoid chondroid tissue formation can be observed, depending composition material. It shown that (1) solubility glasses cannot directly related reactivity...
Myocarditis in response to COVID-19 vaccination has been reported since early 2021. In particular, young male individuals have identified exhibit an increased risk of myocardial inflammation following the administration mRNA-based vaccines. Even though first epidemiological analyses and numerous case reports investigated potential relationships, endomyocardial biopsy (EMB)-proven cases are limited. Here, we present a comprehensive histopathological analysis EMBs from 15 patients with reduced...
Abstract The interface of alkali‐poor glass ceramic implanted in femora male Sprague‐Dawley rats shows soft tissue, chondroid, osteoid, and bone connection with the implant. ultrastructure tissue mainly exhibits a corrosion process, during which dissolution crystalline phase precedes glassy phase. Macrophages are involved this process phagocytosing debris removing as well dissolving remainders ceramic. Under circumstances not yet fully understood, stops, ground substance like material is...
Abstract A direct physicochemical bond between alkali‐rich bioglass or glass ceramic (45 S 5 and B, Hench) alkali‐poor (KG S, Brömer) bone has been well documented. Since long‐term studies have revealed the interface to be subjected remodeling of increased focal disintegration implant, ceramics reduced solubility developed by lowering Na 2 O content adding Al 3 , Ta TiO Sb . Implants KG different compositions with studied histologically 14, 29, 30, 60, 119, 245 days after implantation in...
Current light microscopic methods such as serial sectioning, confocal microscopy or multiphoton are severely limited in their ability to analyse rather opaque biological structures three dimensions, while electron optical offer either a good three-dimensional topographic visualization (scanning microscopy) high-resolution imaging of very thin samples (transmission microscopy). However, sample preparation commonly results significant alteration and the destruction integrity specimen....
A simple new method is described for the histological evaluation of bones containing alloplastic implants ceramic and/or metallic materials. undecalcified bone embedded in acrylic resin and section at 50-200 μm using a sawing microtome. One surface preparation stained up to 10 deep by floating on Giemsa stain. Other staining procedures are possible. Microscopic detail Satisfactory morphometric evaluation.
Abstract Parvovirus B19 (PVB19) is a member of the human erythrovirus family detected frequently in endomyocardial biopsies from patients with dilated cardiomyopathy. Human erythroviruses cluster into three genotypes 1–3 which share high degree homology between major structural proteins and may cause indistinguishable infections clinically serologically. In cardiac tissue other than PVB19 have not yet been reported. Three hundred seventeen consecutive symptomatic cardiomyopathy (median left...
AimsImprovement of clinical diagnostics idiopathic giant cell myocarditis (IGCM) and cardiac sarcoidosis (CS), two frequently fatal human myocardial diseases. Currently, IGCM CS are diagnosed based on differential patterns inflammatory infiltration non-caseating granulomas in histological sections endomyocardial biopsies (EMBs), after heart explantation or postmortem. We report a method for improved diagnosis by gene expression profiling EMBs.
In this study, rat bone marrow cells (RBM) were used to evaluate two biodegradable calcium phosphate cements and bioactive ceramics. The substances investigated were: novel cements, Biocement F H, tricalcium (TCP), surface-modified alpha-tricalcium [TCP (s)] a rapid resorbable ceramic consisting of CaKPO(4) (sample code R5). RBM cultured on disc-shaped test substrates for 14 days. culture medium was changed daily also examined calcium, phosphate, potassium concentrations. Specimens evaluated...
This article reports on the reaction of bone to a new family nanocrystalline hydroxyapatite biomaterials with crystal sizes similar those human bone. Pure nanoapatite cylinders and organoapatite containing synthetic nanopeptide were analyzed 28 days after implantation into spongy Chinchilla rabbits. The experimental techniques used for analysis light microscopy, scanning electron transmission microscopy. Both implant types well incorporated, interface events found be observed surfaces regard...
