A large panorama of lesions is accessible to fine-needle aspiration cytology (FNAC). This chapter focuses on lesions of the salivary glands, as well as tumors of the tongue and oral and nasal cavities. Some unusual lesions of the neck will also be presented. Aspiration cytology of thyroid, parathyroid, and lymph nodes is dealt with in other chapters. When confronted with a mass lesion in the head

Instantaneous wave free ratio (iFR) may be a viable alternative to FFR. iFR is a novel measurement of the hemodynamic relevance of coronary lesions which doesn’t require the use of hyperemic agents.

This chapter describes the different types of non-continent urinary diversions, discusses indications, and summarizes common general and specific complications as well as the issue of quality of life. Non-continent urinary diversions are frequently used for lower urinary tract reconstruction after radical cystectomy. Ileal conduits are the most common form of incontinent diversion, followed by col

In 1952, plans to convert Lake Sanabria (Zamora) into a reservoir for hydroelectric production sparked a press campaign that reached the front pages of the Spanish national press. At the intersection of environmental and political history, this article examines the controversy surrounding the protection of the lake and its designation as a «Picturesque Site» («Paraje Pintoresco») in 1953, under th

Background: Glatiramer acetate (GA) is a well-established treatment option for patients with clinically isolated syndrome and relapsing–remitting multiple sclerosis (MS) with few side effects. The double transgenic mouse model spontaneous opticospinal encephalomyelitis (OSE), based on recombinant myelin oligodendrocyte glycoprotein35-55 reactive T and B cells, mimicks features of chronic inflammat

Neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein-antibody-associated disease (MOGAD) are antibody mediated CNS disorders mostly affecting the optic nerve and spinal cord with potential severe impact on the visual pathway. Here, we investigated inflammation and degeneration of the visual system in a spontaneous encephalomyelitis animal model. We used double-tra

Low-grade superficial connective tumors are a heterogeneous group of benign/reactive, intermediate—locally aggressive and intermediate—rarely metastasizing lesions arising in skin and subcutaneous/superficial soft tissues. The most common targets for fine needle aspiration (FNA) in this group of lesions are schwannomas, desmoids, and “pseudosarcomatous lesions” such as nodular fasciitis. Experienc

Objective: Progressive multiple sclerosis is characterized by chronic inflammation with microglial activation, oxidative stress, accumulation of iron and continuous neurodegeneration with inadequate effectiveness of medications used so far. We now investigated effects of iron on microglia and used the previously identified neuroprotective antipsychotic clozapine in vitro and in chronic experimenta

Hållbarhetskommunikation tar sig an några av samhällets mest angelägna och komplexa utmaningar. Denna avhandling fördjupar området genom att lyfta fram komplexitet som ett definierande kännetecken för strategisk hållbarhetskommunikation, ett perspektiv som i stort sett har försummats. Den utmanar den dominerande organisationscentriska ansatsen som betraktar kommunikation som ett medel för att uppnSustainability communication confronts some of society’s most pressing and complex challenges. This thesis advances the field by highlighting complexity as a defining characteristic of strategic sustainability communication, a perspective that has been largely neglected. It challenges the dominant organization-centric approach that frames communication as an instrument for achieving corporate goal

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune-inflammatory CNS disease affecting spinal cord and optic nerves, mediated by autoantibodies against aquaporin-4 (AQP4) and myelin-oligodendrocyte-glycoprotein (MOG). Effects of those immunoglobulins (Ig) on retina and optic nerve are incompletely understood. We investigated AQP4-IgG and MOG-IgG sera on retina and optic nerve ex vivo a

The main use of splenic fine needle aspirations (FNAs) is to diagnose primary tumors or tumorlike lesions including metastases and to assess splenic involvement of some hematopathological disorders. This chapter deals with disorders likely to be encountered in FNAs from the spleen in everyday practice.

Background: Cranial irradiation is a common therapy for the treatment of brain tumors, but unfortunately patients suffer from side effects, particularly cognitive impairment, caused by neurodegenerative and neuroinflammatory mechanisms. Finding a therapeutic agent protecting hippocampal neurons would be beneficial. Fingolimod (FTY720), a sphingosine-1-phosphate receptor modulator approved for mult

Environmental triggers acting at the intestinal barrier are thought to contribute to the initiation of autoimmune disorders. The transforming growth factor beta inhibitor Smad7 determines the phenotype of CD4+ T cells. We hypothesized that Smad7 in intestinal CD4+ T cells controls initiation of opticospinal encephalomyelitis (OSE), a murine model of multiple sclerosis (MS), depending on the presen

Objective: Dimethyl fumarate (DMF) exerts immunomodulatory and neuroprotective effects in the animal model of experimental autoimmune neuritis (EAN) in the Lewis rat. DMF has been shown to modulate gut microbiota in veterinary medicine, however the effects of oral DMF on the gut-associated lymphoid tissue (GALT) remain unknown. Methods: Lewis rats were treated orally twice daily with DMF up to day

Detta arbete analyserar implementeringen av bestämmelser i EU-förordningen om kritiska råmaterial (CRMA) som fastställer tidsfrister, de strategiska projektens prioritetsstatus samt införandet av en kontaktpunkt i det svenska rättssystemet. Uppsatsen undersöker handläggningstiderna i den svenska tillståndsprocessen, hur processen uppfattas ur ett effektivitetsperspektiv samt vilka delar som av oliThis study examines the implementation of key provisions in the EU Critical Raw Materials Act (CRMA) within the Swedish legal framework, focusing on newly established time limits, the prioritisation status granted to strategic projects, and the introduction of a single national contact point. The thesis investigates the current duration of Swedish permitting procedures, how the process is perceive

Background: Most multiple sclerosis (MS) patients succumb to a progressive phenotype. Continued lymphocyte activity in the brain, microglia-mediated injury, iron deposition, and oxidative stress are characteristics of progressive MS. Objective: As minocycline and hydroxychloroquine have been shown to inhibit microglia, we evaluated their effects on other outcomes relevant for progression. Methods:

In acute lymphoblastic leukemia (ALL), steroid resistance and hypovitaminosis D are both associated with a poor prognosis. We show that methylprednisolone, calcitriol and the AKT-inhibitor MK-2206 have a synergistic effect on the apoptosis of steroid resistant T-ALL cells. Compared to methylprednisolone monotherapy, calcitriol increases methylprednisolone induced apoptosis dose-dependently (1.37–1
