De flesta associerar förmodligen ordet katalysator med bilkatalysatorer där smutsiga avgaser från fordon renas genom att gasen får reagera med syre och därmed bilda mindre skadliga produkter. Så kallade heterogena katalysatorer är ofta metalloxider och de används i många industrier för att möjliggöra kemiska reaktioner. Ett sådant exempel är Formox-processen, där en katalysator bestående av järnmoIn the Formox-process, methanol is converted to formaldehyde via partial oxidation on a heterogeneous iron-molybdate catalyst. To an extent, the formed formaldehyde (FA) is over-oxidized into carbon monoxide (CO) which cannot be recycled into FA. As CO affects the environment negatively and decreases the process economy, internal attempts have previously been made to decrease the CO formation of t

Abstract in Spanish Tanto el cine como el concepto de género en la teoría queer comparten dos aspectos fundamentales: ambos son performativos y son entendidos como construcciones sociales. La teoría queer hoy en día sigue provocando reacciones adversas en la forma de entender el sexo, el género y la sexualidad y el cine de Almodóvar sigue siendo actual con el paso de los años. Éstas son las causasCinema and gender in queer theory share two fundamental aspects: both are performative and understood as social constructions. Nowadays, queer theory still causes adverse reactions with respect to the understanding of sex, gender and sexuality and Almodóvar's films have remained relevant until today. These two reasons lead us to the idea of looking at the film High Heels (Pedro Almodóvar, 1991) fr

Anhedoni, minskad motivation att uppleva lust, är associerad med förändringar i belöningssystemet. Belägen i ventrala striatum utgör den bilaterala nucleus accumbens (NAcc) den centrala noden i detta nätverk, där dopamin agerar som huvudsaklig excitatorisk neurotransmitter. Studier med funktionell magnetresonanstomografi (fMRI) har visat att aktiviteten i ventrala striatum minskar under belöningsbAnhedonia, reduced motivation to experience pleasure, is associated with alterations in the circuitry of the reward system. Located in the ventral striatum, the bilateral nucleus accumbens (NAcc) is the central hub of this network where dopamine acts as the main excitatory neurotransmitter. Studies using functional magnetic resonance imaging (fMRI) found that activity in the ventral striatum is de

Transfusion-related acute lung injury (TRALI) remains a leading cause of transfusionrelated deaths. In most cases, anti-leukocyte antibodies in the transfusion product trigger TRALI, but not all anti-leukocyte antibodies cause TRALI. It has been shown that the anti-major histocompatibility complex (MHC) class I antibody 34-1-2S (anti-H-2Kd) causes TRALI in BALB/c mice (MHC class I haplotype H-2Kd)

Background and Purpose-We have previously shown that delivery of brain-derived neurotrophic factor (BDNF) through direct intrahippocampal gene transduction with a viral vector suppresses the formation of new dentate granule cells triggered by global forebrain ischemia. Here, we investigated whether inhibition of endogenous BDNF alters ischemia-induced neurogenesis in the dentate gyrus. Methods-Rat
