This article will reveal how local scientific determination and ambition, in the face of rejection by funders, navigated a path to success and to influence in national policy and international medicine. It will demonstrate that Birmingham, England's 'second city', was the key centre for cutting-edge biological psychiatry in Britain in the 1920s and 1930s. The ambitions of Frederick Mott - doyen of biochemistry, neuropathology and neuropsychiatry, until now celebrated as a London figure - to revolutionize psychiatric treatment through science, chimed with those of the City and University of Birmingham's Joint Board of Research for Mental Diseases. Under Mott's direction, shaped by place and inter-professional working, the board's collaborators included psychiatrist Thomas Chivers Graves and world-renowned physiologist J.S. Haldane. However, starved of external money and therefore fresh ideas, as well as oversight, the 'groupthink' that emerged created the classic UK focal sepsis theory which, it was widely believed, would yield a cure for mental illness - a cure that never materialized. By tracing the venture's growth, accomplishments and contemporary potential for biochemical, bacterial and therapeutic discoveries - as well as its links with scientist and key government adviser Solly Zuckerman - this article illustrates how 'failure' and its ahistorical assessment fundamentally obscure past importance, neglect the early promise offered by later unsuccessful science, and can even hide questionable research.Robert Maxwell Young's first book Mind, Brain and Adaptation in the Nineteenth Century (1970), written from 1960 to 1965, still merits reading as a study of the naturalization of mind and its relation to social thought in Victorian Britain. I examine the book from two perspectives that give the volume its unique character first, Young's interest in psychology, which he considered should be used to inform humane professional practices and be the basis of social reform; second, new approaches to the history of scientific ideas. I trace Young's intellectual interests to the Yale Philosophy Department, the Cambridge Department of Experimental Psychology and a new history and philosophy of science community. Although Young changed his political outlook and historiography radically after 1965, he always remained faithful to ideas about thought and practice described in Mind, Brain.This, the second in a series of articles present a new framework for considering the computation of uncertainty in electron excited X-ray microanalysis measurements, will discuss matrix correction. The framework presented in the first article will be applied to the matrix correction model called "Pouchou and Pichoir's Simplified Model" or simply "XPP." This uncertainty calculation will consider the influence of beam energy, take-off angle, mass absorption coefficient, surface roughness, and other parameters. Since uncertainty calculations and measurement optimization are so intimately related, it also provides a starting point for optimizing accuracy through choice of measurement design.

Chronic rhinosinusitis is associated with altered mucociliary clearance and olfaction. The study aimed to analyse the reversibility of impairment and endoscopic factors predicting changes in mucociliary clearance and olfactory parameters.

This prospective study included patients undergoing functional endoscopic sinus surgery for medically refractory chronic rhinosinusitis. Pre- and post-operative measurements of mucociliary clearance, olfactory thresholds, and identification scores were recorded.

Of the 96 patients, 65.6 per cent had polyposis and 80.2 per cent underwent primary surgery. Improvements in mucociliary clearance and olfaction scores were seen in all patients, with greater reversibility of impairment in patients with polyposis and in those who underwent revision surgery. The presence of polyps correlated significantly with changes in mucociliary clearance and olfaction.

The study highlights improvements in mucociliary clearance, olfactory thresholds and identification scores after functional endoscopic sinus surgery in chronic rhinosinusitis with or without nasal polyposis, as well as for primary and revision surgeries. Adequate post-operative care and prevention of polyps recurrence help to improve mucociliary clearance and olfaction scores.

Whereas numerous experimental and clinical studies suggest a complex involvement of serotonin in the regulation of anxiety, it remains to be clarified if the dominating impact of this transmitter is best described as anxiety-reducing or anxiety-promoting. The aim of this study was to assess the impact of serotonin depletion on acquisition, consolidation, and expression of conditioned fear.

Male Sprague-Dawley rats were exposed to foot shocks as unconditioned stimulus and assessed with respect to freezing behaviour when re-subjected to context. selleck inhibitor Serotonin depletion was achieved by administration of a serotonin synthesis inhibitor, para-chlorophenylalanine (PCPA) (300mg/kg daily×3), (i) throughout the period from (and including) acquisition to (and including) expression, (ii) during acquisition but not expression, (iii) after acquisition only, and (iv) during expression only.

The time spent freezing was significantly reduced in animals that were serotonin-depleted during the entire period from (and including) acquisition to (and including) expression, as well as in those being serotonin-depleted during either acquisition only or expression only. In contrast, PCPA administrated immediately after acquisition, that is during memory consolidation, did not impact the expression of conditioned fear.

Intact serotonergic neurotransmission is important for both acquisition and expression of context-conditioned fear.
