Background: Less than half of patients with major depressive disorder (MDD) respond to their first antidepressant trial. Our understanding of the underlying mechanisms of selective serotonin reuptake inhibitors (SSRIs) remains poor, and there is no reliable method of predicting treatment response. Methods: Thirty-seven MDD subjects and 41 healthy controls, somatically healthy and medication-free f

The effect of different glutamate‐receptor antagonists on the induction of cortical spreading depression of Leao and of cortical anoxic membrane depolarization were investigated in the anaesthetized rat. Spreading depression (SD), elicited by mechanical stimulation of the cortical surface, was inhibited by the non‐competitive N‐methyl‐d‐aspartate (NMDA)‐receptor blocker, (±)‐5‐methyl‐10,11‐dihydro

The effect of cerebral ischemia on the activity of pyruvate dehydrogenase (PDH) enzyme complex (PDHC) was investigated in homogenates of frozen rat cerebral cortex following 15 min of bilateral common carotid occlusion ischemia and following 15 min, 60 min, and 6 h of recirculation after 15 min of ischemia. In frozen cortical tissue from the same animals, the levels of labile phosphate compounds,

The effect of an α-2 receptor antagonist, idazoxan, on ischemic neuronal damage in the hippocampus and neocortex was studied in rats following 10 min of forebrain ischemia. Idazoxan was given 0.1 mg/kg i.v. immediately after recirculation, followed by 48 h of continuous infusion at a rate of 10 μg/kg/min. A histopathological examination of the CA1 region of the dorsal hippocampus and neocortex fro

Changes in the levels of arachidonic acid during ischemia in selectively vulnerable areas of the hippocampus were studied in the rat brain. Since neurons in the CA1 region are more vulnerable to ischemia than neurons in the adjacent CA3 region, the release of arachidonic acid in these two regions was measured during decapitation ischemia of 4- to 12-min duration. The concentration of free arachido

This study addresses the question of whether the cyclooxygenase inhibitors indomethacin and diclofenac and the glucocorticosteroid dexamethasone ameliorate neuronal necrosis following cerebral ischemia. In addition, since these drugs inhibit the production of prostaglandins and depress phospholipase A2 activity, respectively, the importance of free fatty acids (FFAs) on the development of ischemic

The recent Company of Biologists workshop 'Growth, Division and Differentiation: Understanding Developmental Control', which was held in September 2011 at Wiston House, West Sussex, UK, brought together researchers aiming to understand cell proliferation and differentiation in various metazoans, ranging from flies to mice. Here, we review the common themes that emerged from the meeting, highlighti

This is an overview article regarding artificial intelligence (AI) and its potential normative implications. Technology has always had inherent normative consequences not least due to AI and the use of algorithms. There is a crucial difference between algorithms in a technical sense and from a social-science perspective. It is a question of different orders of normativity - the first related to th

Den andra av två artiklar rörande det fängelse, den s k proban, som Lunds universitet hade under den tid lärosätet ägde egen jurisdiktion över anställda och studenter. Denna andra del behandlar studentoroligheter under tidigt 1800-tal, den oklara frågan var proban var placerad under 1800-talet samt några av de sista studenterna att spärras in häri under 1830- och 1840-talen, dels för brott, dels s

This paper examines virtual manifestations of “sad girls” on the media platform Tumblr. Here users write about their struggles with mental illness, revealing a set of shared experiences that encompass both psyche and body. Predominant narratives of what it means to be mentally ill are questioned, and alternative conceptualizations of the psyche are introduced. I argue that the sad girls legitimize

Utbildningsstyrelsen har i samarbete med undervisnings- och kulturministeriet börjat utveckla rektorsutbildningarna mera målmedvetet än tidigare, i synnerhet de utbildningsprogram för läroanstalternas ledning som finansieras via programmet Kunnig (Osaava). En åtgärd som ansetts vara nödvändig som underlag för utvecklingsarbetet har varit att kartlägga olika länders praxis för utbildning av läroansThe Finnish National Board of Education, in collaboration with the Ministry of Education and Culture, has started to develop the training of rectors in a more systematic way by utilizing the funds which were allocated for the Osaava programme. One of the pre-liminary measures in this regard included a survey concerning the continuing education practices of school leaders on a worldwide basis. The

This study follows on from a network-based assessment redesign project at a Canadian university, to investigate factors relating to academic engagement and sustained implementation. The project was designed with mini-grants, embedded support and a community of practice. Assessment facilitators worked in discipline clusters to achieve mutual goals for assessment reform targeted at authentic develo

I am not convinced that the challenge for self-adaptive software is how to handle unexpected changes. I believe that the real challenge is how to characterise the uncertainty that the self-adaptive software has to handle. Once a proper characterisation of the uncertainty is in place, I think handling unanticipated changes and situations becomes a lot simpler. What is difficult is to know what rang
