Anthropological inquiry has often been considered an agent of intellectual secularization. Not least is this so in the sphere of religion, where anthropological accounts have often been taken to represent the triumph of naturalism. This metanarrative however fails to recognise that naturalistic explanations could sometimes be espoused for religious purposes and in defence of confessional creeds. This essay examines two late nineteenth-century figures – Alexander Winchell in the United States, and William Robertson Smith in Britain – who found in anthropological analysis resources to bolster rather than undermine faith. In both cases these individuals found themselves on the receiving end of ecclesiastical censure and were dismissed from their positions at church-governed institutions. But their motivation was to vindicate divine revelation, in Winchell’s case from the physical anthropology of human origins and in Smith’s from the cultural anthropology of Semitic ritual.

INTRODUCTION:Cerebral small-vessel disease has been implicated in the development of Alzheimer’sdisease (AD). The retinal microvasculature enables non-invasive visualization andevaluation of the systemic microcirculation. We evaluated retinal microvascular parametersin a case-control study of AD patients and cognitively-normal controls.
METHODS:Retinal images were computationally analyzed and quantitative retinal parameters (caliber,fractal dimension, tortuosity, and bifurcation) measured. Regression models were used tocompute odds ratios (OR) and confidence intervals (CI) for AD with adjustment forconfounders.
RESULTS:Retinal images were available in 213 AD participants and 294 cognitively-normal controls.Persons with lower venular fractal dimension (OR per standard deviation [SD] increase, 0.77[CI: 0.62–0.97]) and lower arteriolar tortuosity (OR per SD increase, 0.78 [CI: 0.63–0.97])were more likely to have AD following appropriate adjustment.
DISCUSSION:Patients with AD have a sparser retinal microvascular network and retinal microvascularvariation may represent similar pathophysiological events within the cerebralmicrovasculature of patients with AD.

Background: Late-onset Alzheimer's disease (AD) is heritable with 20 genes showing genome-wide association in the International Genomics of Alzheimer's Project (IGAP). To identify the biology underlying the disease, we extended these genetic data in a pathway analysis.
Methods: The ALIGATOR and GSEA algorithms were used in the IGAP data to identify associated functional pathways and correlated gene expression networks in human brain.
Results: ALIGATOR identified an excess of curated biological pathways showing enrichment of association. Enriched areas of biology included the immune response (P = 3.27 X 10(-12) after multiple testing correction for pathways), regulation of endocytosis (P = 1.31 X 10(-11)), cholesterol transport (P = 2.96 X 10(-9)), and proteasome-ubiquitin activity (P = 1.34 X 10(-6)). Correlated gene expression analysis identified four significant network modules, all related to the immune response (corrected P = .002-.05).
Conclusions: The immime response, regulation of endocytosis, cholesterol transport, and protein ubiquitination represent prime targets for AD therapeutics. (C) 2015 Published by Elsevier Inc. on behalf of The Alzheimer's Association.

To assess factors influencing the success of whole-genome sequencing for mainstream clinical diagnosis, we sequenced 217 individuals from 156 independent cases or families across a broad spectrum of disorders in whom previous screening had identified no pathogenic variants. We quantified the number of candidate variants identified using different strategies for variant calling, filtering, annotation and prioritization. We found that jointly calling variants across samples, filtering against both local and external databases, deploying multiple annotation tools and using familial transmission above biological plausibility contributed to accuracy. Overall, we identified disease-causing variants in 21% of cases, with the proportion increasing to 34% (23/68) for mendelian disorders and 57% (8/14) in family trios. We also discovered 32 potentially clinically actionable variants in 18 genes unrelated to the referral disorder, although only 4 were ultimately considered reportable. Our results demonstrate the value of genome sequencing for routine clinical diagnosis but also highlight many outstanding challenges.

O presente trabalho é o resultado duma investigação heurística sobre os efeitos do estudo da Técnica Alexander (TA) na prática e no ensino da flauta. Submeti-me a uma centena de aulas de Técnica Alexander e procedi a uma análise reflexiva da minha aprendizagem e prática individual e pedagógica, registando a sua evolução através da progressiva incorporação dos princípios e metodologias daquela técnica. A primeira parte descreve os princípios e procedimentos da TA enquadrando-a na problemática das relações entre conhecimento tácito e explícito, nos processos de controlo motor voluntário e involuntário, e na eficácia e eficiência dos automatismos neuromusculares. A segunda parte constitui a descrição e análise do processo transformador catalisado pelo estudo da TA: modificações na coordenação muscular; na técnica respiratória; no empunhar da flauta e na preparação para a emissão da primeira nota, e na relação entre o equilíbrio do instrumento e o movimento dos dedos. Vários procedimentos e exercícios desenvolvidos para a resolução de problemas pessoais são apresentados justificando a sua eficácia. A TA não proporciona apenas alterações na coordenação muscular mas pode modificar os processos mentais. Por isso alguns princípios para uma organização eficiente da prática são discutidos e concretizados nalguns exercícios que promovem maior variabilidade, alternância entre análise e integração e clareza na concepção do gesto técnico-musical. Por último, a evolução da minha abordagem pedagógica, incorporando procedimentos inspirados na TA e desenvolvidos ao longo da investigação são ilustrados com alguns alunos. A tese argumenta que a TA pode desempenhar um papel fundamental na melhoria do desempenho dum músico e revela-se uma ferramenta pedagógica que merece ser explorada mais sistematicamente num ensino mais baseado numa experimentação guiada que promova uma maior autoconsciência dos processos neuromusculares do que na instrução prescritiva e explícita.
