Das Verhalten des Trabeculum corneo-sclerale nach Implantation in die Augenvorderkammer bei Primaten

1962

Um das reaktive Verhalten des Trabeculum corneo-sclerale unter Bedingungen der Gewebekultur zu prufen, wurden bei Meerkatzen (Cercopithecus aethiops) Auto- und Heterotransplantationen von Kammerwinkelgewebsstucken (Elliot-Trepanate) in die Augenvorderkammer durchgefuhrt. Die lichtmikroskopische und histochemische Aufarbeitung des Materials zeigte, das das normalerweise hochdifferenzierte Trabekelwerk des Implantates vom 3. Tag post operationem zunehmend entdifferenziert. Zuerst gingen die spezialisierten Endothelien der Innenwand des Schlemmschen Kanals, spater die Trabekelmembranen und die intertrabekularen Stromungskanalchen verloren. Die lamellare Ordnung war nicht mehr erkennbar. Das Ge…

Ultrastructure of Human Spinal Trabecular Arachnoid

2014

The arachnoid trabecular layer, located internally to the arachnoid layer, is composed of fibers that form the spider web–like trabecular structure found in the subarachnoid space and in the adventitial layer of blood vessels. The arachnoid trabeculae give shape to tubular structures (arachnoid sheaths) for each nerve root and for the spinal cord. Some of these arachnoid trabeculae extend to the pia mater. The trabecular arachnoid is an extremely fragile structure, which can easily be damaged. Because of its fragility, this membrane may be destroyed during dissection and manipulation, so that it is not frequently seen or systematically described. Trabecular arachnoid limits nerve root movem…

Mechanical rotational thrombectomy with Rotarex system augmented with drug-eluting balloon angioplasty vs. stenting for the treatment of acute thromb…

2018

Introduction Mechanical thrombectomy is an alternative to local thrombolysis for the treatment of severe ischaemia in the femoropopliteal segment, but stent implantation is usually required after this procedure. The use of drug-eluting balloons (DEBs) may overcome long-term problems associated with stents, but it remains unclear how often such a treatment is technically feasible and efficient. Aim This post hoc single-centre study was aimed at assessment of the feasibility, safety and efficacy of mechanical thrombectomy followed by application of DEBs. Material and methods Fifty-one patients, aged 69.1 ±11.6 years, were managed for acute thrombotic or chronic critical ischaemia in the femor…

Delayed brain reexpansion in schizophrenic patient affected by trabecular type chronic subdural hematoma

2021

Background: Chronic subdural hematoma (cSDH) represents a complex and unpredictable disease, characterized by high morbidity and mortality, especially in elderly patients. Factors affecting the postoperative brain reexpansion along to cSDH recurrence have not been yet adequately investigated. The authors presented the case of a schizophrenic patient affected by trabecular type cSDH that presented a delayed brain reexpansion despite a craniotomy and membranotomy. Case Description: A 51-year-old female patient with diagnosis of schizophrenia was admitted to the emergency department with GCS score of 5/15 and right anisocoria. An urgent brain CT revealed a trabecular right cSDH (35 mm in maxi…

Proteome alterations in aqueous humour of primary open angle glaucoma patients.

2019

Aim To unravel the primary open angle glaucoma (POAG) related proteomic changes in aqueous humour (AH). Methods Totally 35 patients listed for cataract surgery (controls: n=12, age: 67.4±13.6y) or trabeculectomy for POAG (n=23, age: 72.5±8.3y) were included. AH samples of those patients were obtained during cataract surgery or trabeculectomy. AH samples were subsequently pooled into the experimental groups under equal contribution in terms of protein amount of each individual patient. Protein samples were analyzed by a linear trap quadrupol Orbitrap Mass Spectrometry device with an upstream liquid chromatography system. The obtained raw data were analyzed using the Maxquant proteome softwar…

Impact of estrogens on atherosclerosis and bone in the apolipoprotein E-deficient mouse model.

2014

Objective The common inflammatory pathophysiology has nourished the hypothesis of a relationship between osteoporosis and cardiovascular disease. Estrogens are key agents in the modulation of both processes. We investigated whether induction of atherosclerosis affects bone and whether estrogens modulate both processes. Methods Female apolipoprotein E-deficient mice (a well-established model of atherogenesis) were ovariectomized or falsely operated and fed either standard diet or high-fat diet (HFD). Six animals were included in each of the four groups. To clarify mechanisms, we treated preosteoblastic MC3T3-E1 cells with mouse serum. Results Physiological levels of estrogens in falsely oper…

Stroke Care Within the COVID-19 Pandemic—Increasing Awareness of Transient and Mild Stroke Symptoms Needed

2020

Background: The COVID-19 pandemic might affect health care resources and alter patient admission to hospital in case of stroke or transient ischemic attack (TIA). We aim to determine whether the COVID-19 pandemic is affecting utilization of recanalization procedures and numbers of patients with stroke and TIA admitted to a primary care stroke center.Methods: In this retrospective observational study, we compared patients admitted from January 2019 until February 2020 with patients admitted during the COVID-19 pandemic (March/April 2020) in Germany. We included patients with stroke (hemorrhagic or ischemic) or TIA as classified by International Statistical Classification of Diseases and Rela…

This multicenter research investigates the effects of dance movement therapy (DMT) on participants diagnosed with depression. In total, 109 persons participated in the study in various locations in Finland. The participants were 39 years old, on average (range = 18-64 years), and most were female (96%). All participants received treatment as usual (TAU). They were randomized into DMT + TAU (n = 52) or TAU only (n = 57). The participants in the DMT + TAU group were offered 20 DMT sessions twice a week for 10 weeks in addition to standard care. The measurement points included pretreatment measurement at the baseline, posttreatment measurement at the end of the intervention, and a follow-up me…

Purpose To compare two surgical approaches for treating encapsulated blebs after trabeculectomy with mitomycin C, in terms of the development of intraocular pressure and progression of glaucoma in a long-term follow up: 1. bleb needling alone vs. 2. a combined approach of needling with additional transconjunctival scleral flap sutures, to prevent early ocular hypotony. Methods Forty-six patients with failing blebs after trabeculectomy with mitomycin C were enrolled in this study. Patients received either needling revision alone (group 1; n = 23) or a combined needling with additional transconjuctival flap sutures, if intraoperatively the intraocular pressure was estimated to be low (group 2…
