Gendered Violence Online : Hate Speech as an Intersection of Misogyny and Racism
2020
Social media has been adopted by radical right populists and alt-right demagogues as a platform for circulating misogynous and racist hate speech and affectively mobilising supporters. This chapter examines hate speech as a form of gendered and racist violence, focusing on social media posts by two influential right-wing populist politicians: Jussi Halla-aho, the leader of the Finns Party, and Donald Trump, the president of the United States. It demonstrates how these politicians intertwine misogyny and racism in blog posts and tweets that target women in particular. Their affective online communication is interpreted as a new form of violence. This digitally mediated violence, although a r…
Structure and Function of Desmosomes
2007
Desmosomes are prominent adhesion sites that are tightly associated with the cytoplasmic intermediate filament cytoskeleton providing mechanical stability in epithelia and also in several nonepithelial tissues such as cardiac muscle and meninges. They are unique in terms of ultrastructural appearance and molecular composition with cell type-specific variations. The dynamic assembly properties of desmosomes are important prerequisites for the acquisition and maintenance of tissue homeostasis. Disturbance of this equilibrium therefore not only compromises mechanical resilience but also affects many other tissue functions as becomes evident in various experimental scenarios and multiple diseas…
Mechanisms of Cell-Volume Regulation in the Central Nervous System
2017
Function and viability of every cell is dependent on the proper control of its shape and volume. In the brain, which is protected by a rigid outer shell, cell-volume regulation is of particular importance, since large volume changes affect cerebral perfusion and, hence, function. Neuronal activation leads to constant changes of the ionic and metabolic composition of the brain’s extracellular space. These changes are buffered by astrocytes on the expense of constant changes in cell volume. Under pathological conditions, the ability of astrocytes to maintain the homeostasis of the brain is overwhelmed and permanent cell swelling, cytotoxic edema, occurs. The current chapter describes the prin…
Superfood for axons: Glial exosomes boost axonal energetics by delivery of SIRT2
2021
Axon integrity depends on support by glia facilitating axonal maintenance and energy homeostasis, but the molecular mechanisms are not well understood. In this issue of Neuron, Chamberlain et al. (2021) provide evidence that oligodendrocyte-to-axon transfer of SIRT2 via extracellular vesicles (exosomes) enables deacetylation of mitochondrial proteins, enhancing axonal energy production.
Functional In Vitro Studies Of Buffy Coat Pooled Platelets Cryopreserved In Dimethyl-Sulphoxide With a New System
2013
Abstract Introduction Cryopreservation for long term storage of platelets (PLTs) represents a clinical useful method for avoiding platelet shortage. Many studies have tried to define, in vitro and in vivo, the entity and weight of storage-related PLTs lesions with discordant results related to different methods. We have performed an in vitro prospective study to evaluate PLTs count, viability and function of buffy coat derived pooled platelet concentrates (BC-PLTs) treated with dimethyl-sulphoxide (DMSO) and cryopreserved at -80°C with an innovative patented system not requiring laminal flow hoods and external manipulations. Materials and methods Each BC-PLTs was obtained from 5 buffy coats…
Aldara-Induced Psoriasis-Like Skin Inflammation: Isolation and Characterization of Cutaneous Dendritic Cells and Innate Lymphocytes
2014
Psoriasis is a chronic auto-inflammatory skin disease of unknown etiology affecting millions of people worldwide. Dissecting the cellular networks and molecular signals promoting the development of psoriasis critically depends on appropriate animal models. Topical application of Aldara cream containing the Toll-like receptor (TLR)7-ligand Imiquimod induces skin inflammation and pathology in mice closely resembling plaque-type psoriasis in humans. The particular power of the Aldara model lies in examining the early events during psoriatic plaque formation, which is difficult to achieve in patients. Hence, recent reports using this model have challenged currently prevailing concepts concernin…

2017
We have read with great interest the article published by Tiwari et al, “Computer-Extracted Texture Features to Distinguish Cerebral Radionecrosis from Recurrent Brain Tumors on Multiparametric MRI: A Feasibility Study.”[1][1] In their article, they refer to our work regarding brain metastasis
Monoclonal antibody 3H8: A useful tool in the diagnosis of candidiasis
1999
In a previous series of experiments six mAbs were obtained against cell wall extracts of Candida albicans ATCC 26555. After several studies only one of them, designated 3H8, has been used to produce a commercial kit for the rapid diagnosis of candidiasis, Bichro-latex albicans (Fomouze Diagnostics). The present study involved the generation and characterization of this mAb as an immunoglobulin G1 which recognizes mannoproteins of high molecular mass present in the C. albicans cell wall. ELISA assays showed that the presence of the epitope recognized by mAb 3H8 was similar in both yeast and mycelial cell walls of C. albicans, in contrast to the epitope for mAb 1B12, which is mainly expressed…
The C-terminal antibody binding domain ofCandida albicansmp58 represents a protective epitope during candidiasis
2003
The 58-kDa surface mannoprotein of Candida albicans (mp58) elicits strong antibody responses during infection. Epitope mapping with sera from patients with candidiasis and control individuals indicated the presence of multiple IgG-reactive continuous epitopes on the protein, expanding both the amino- and carboxy-terminal domains and several internal regions. These immunoreactive regions were similar to the ones previously identified using sera from immunized animals. Two of the epitopic regions (including the C-terminal domain) showed increased reactivity with antibodies present in sera from patients with candidiasis as compared to control individuals. Patients who survived the infection di…
Enzephalopathie nach Intoxikation mit einem Anticholinergikum
2008
A 55-year-old chemical laboratory technician developed mydriasis and ocular hypertension, which lasted for 6 weeks, after synthesizing several kilograms of a scopolamine-related test agent with anticholinergic action and then decanting a powdery intermediary substance, the dust of which he may have inhaled. Six weeks later he suddenly had symptoms of an acute intoxication while synthesizing a scopolamine-related substance. The anticholinergic delirium regressed completely within one day requiring no treatment. But subsequently he developed symptoms of a toxic encephalopathy. This only partially regressed over the following 3 years. Its probable cause is thought to have been either the manif…
