Authors: Agustamia Christine , Widiastuti Ani , Sumardiyono Christanti
Published: February 2017

Resistant varieties are more advisable for controlling maize downy mildew compared with fungicides which is not effective and not environmentally friendly. This study is aimed to determine resistance of some varieties of maize against downy mildew. The maize varieties used were BS 0114, BS 0214, BS 0314, PAC 105, Sweet Corn and BISI 2. The parameters measured were disease incidence and intensity, chlorophyll content of leaves, stomatal density and plants dry weight. Data were analyzed by using analysis of variance (ANOVA) and Duncan's Multiple Range Test (DMRT). The results indicated that PAC 105, BS 0214 and BS 0314 were resistant varieties, while BS 0114, Sweet Corn and BISI 2 were susceptible. PAC 105 variety has the lowest stomatal density (65.353/mm2), and Sweet Corn variety has the highest stomatal density (110.79/mm2). Stomatal density was positively correlated with the disease intensity. Higher disease intensity has lower chlorophyll content compared with the lower intensity. PAC 105 variety has the highest chlorophyll content and plant dry weight, while Sweet Corn variety has the lowest chlorophyll content and plant dry weight. Penggunaan varietas tahan bulai lebih dianjurkan digunakan dalam pengendalian penyakit bulai pada jagung dibandingkan dengan penggunaan fungisida karena tidak efektif dan tidak ramah lingkungan. Penelitian ini bertujuan untuk mengetahui ketahanan beberapa varietas jagung terhadap penyakit bulai. Varietas yang digunakan meliputi BS 0114, BS 0214, BS 0314, PAC 105, jagung manis, dan BISI 2. Parameter yang diamati adalah insidensi dan intensitas penyakit, kandungan klorofil setelah inokulasi, kerapatan stomata dan berat kering tanaman. Data yang diperoleh diuji dengan analisis varians (ANOVA) dan uji lanjut dengan Duncan’s Multiple Range Test (DMRT). Hasil penelitian rumah kaca menunjukkan bahwa varietas PAC 105, BS 0214 dan BS 0314 merupakan varietas tahan, sedangkan varietas BS 0114, jagung manis dan BISI 2 merupakan varietas yang rentan. Varietas tahan PAC 105 memiliki kerapatan stomata paling rendah yaitu 65,353/mm2, dan kerapatan stomata paling tinggi dimiliki oleh varietas rentan yaitu jagung manis dengan kerapatan 110,79/mm2. Kerapatan stomata berkorelasi positif dengan intensitas penyakit dengan koefisien korelasi (r) sebesar 0,72526. Semakin rendah intensitas penyakit bulai kandungan klorofil dan berat kering yang semakin tinggi. Varietas PAC 105 yang mempunyai intensitas penyakit paling rendah , mempunyai kandungan klorofil dan berat kering tertinggi, sedangkan varietas jagung manis mempunyai kandungan klorofil dan berat kering terendah.

These thoughts were inspired by the following riddle: A young man asked a maiden, as she was at an open window, when she would go a walk with him; and he got the answer that follows: “When I shall have lifted the linen (or net), lowered the glass, and put the dead to bury the living.” He, thereupon, giving up hope, sailed to foreign parts; and, returning at the end of three years, he heard she was married to another, but was not at all happy. This grieved him, and, on going to see her, he got the solution of her statement, thus: “As soon as I would have lifted the linen off the table, shut the window, and smoored the fire; and that did not long delay me, though you were impatient.”

Los principales resultados fueron: la magnitud del coeficiente de densificado fue comparable a la reportada en la bibliografía; la velocidad de onda no varió significativamente antes y después del densificado; el densificado incrementó la densidad y el módulo dinámico de la madera de G. americanus.
Identificación de especies del género Ischnosiphon utilizadas por dos comunidades Ticuna del Perú para elaborar sus tejidos tradicionales
Authors: Martín Brañas Manuel , Núñez Pérez Cecilia Del Carmen , Zárate Gómez Ricardo
Published: February 2017

El pueblo ticuna ha ocupado desde tiempos ancestrales el territorio que comprende actualmente la triple frontera entre Brasil, Colombia y Perú, manteniendo, a través de los años y a pesar de la separación limítrofe, ciertos vínculos sociales y culturales, fortalecidos a través del intercambio de saberes y prácticas culturales. En el Perú existe una escueta bibliografía etnobiológica sobre los usos tradicionales que los ticuna dan a las especies vegetales de su entorno, a diferencia de lo que ocurre en Colombia y Brasil.  En ese sentido se llevó a cabo una investigación para identificar las especies del género Ischnosiphon, utilizadas tradicionalmente por dos comunidades ticuna de la cuenca baja del río Amazonas para elaborar sus tejidos utilitarios y rituales. Las comunidades de estudio fueron Bufeo Cocha y Santa Rita de Mochila, ubicadas en el Distrito de Ramón Castilla, Provincia de Mariscal Ramón Castilla, en el Departamento de Loreto (Perú). La investigación permitió determinar el sistema de uso tradicional de las especies del género Ischnosiphon, localmente conocidas como huarumá. Se determinaron tres especies utilizadas por estas comunidades en sus tejidos tradicionales, realizándose la identificación taxonómica de las mismas (I. arouma, I. obliquus, I. puberulus) y registrándose el uso que los ticuna del bajo Amazonas dan a las fibras extraídas de sus tallos.

El método ODIT (Observación, Desarrollo e Ingeniería Turística) y su uso para la planificación estratégica y el desarrollo de los destinos turísticos
Authors: Duarte Pimentel Thiago
Published: February 2017

En el marco de la reciente política brasileña de popularización de la ciencia (scientific alphabetization), este artículo tiene como objetivo presentar y discutir, de manera esquemática, el método de planificación y gestión turística titulado ODIT – Observación, Desarrollo e Ingeniería Turística. Su concepción busca integrar simultáneamente las premisas de sustentabilidad, participación democrática y autogestión con la utilización de procesos y técnicas formales con vistas a alcanzar eficacia técnica y profesionalizar la acción. Para ejecutarlo se hace uso de cuatro dimensiones: económica, social, ética y ambiental, que en suma otorgan una visión general de la visita in situ. Cada una estas dimensiones tiene un rol de indicadores para guiar la recopilación, la sistematización y el análisis de datos. Sin embargo, para tornar más preciso el análisis, la metodología ODIT divide la información en dos niveles: el nivel del territorio y el nivel de las empresas, con el fin de delimitar las escalas de análisis y de acción. En suma, este método se presenta como una de las formas más completas y bien elaboradas de planeación y gestión de los destinos turísticos.

Los peces de Cooper y el género detectivesco: del dominante epistemológico al dominante ontológico
Authors: Alfaro-Vargas Roy
Published: February 2017

Este artículo analiza Los peces de Cooper en relación con los parámetros del género detectivesco clásico y del género detectivesco metafísico, el primero ligado a las poéticas modernistas y el segundo a las postmodernistas. El análisis plantea un choque entre ambas poéticas, a través de la incorporación del elemento ficto-científico de la superconductividad. Asimismo, se interpreta esta novela (Los peces de Cooper) como una literatura experimental anclada en las narrativas innaturales.

The main purpose of this study is explaining the relationship between customers trust, perceived risk and online purchase intention. However, we added e-servicescape as the antecedent of customers trust, perceived risk, and purchase intention. The respondents were 120 online shop customers. The data was processed using SmartPLS 2.0. We found e-Servicescape to be an antecedent of both customer trust and perceived risk, and customer trust to be the antecedent of purchase intention. However, we found that the relationship between customer trust and perceived risk, as well as perceived risk and purchase intention to be insignificant. Our findings and managerial implications are discussed.
Does public spending affect unemployment in an emerging market?

Published: February 2017

The Nigerian economy in the last two decades up until 2013 has been growing at an average of 6% and yet unemployment was equally growing in the region of 20% within the same period. This paradoxical situation has led to a flurry of studies and postulations aimed at providing explanation and solution to the phenomenon. This study making use of a regression model with annual data from 1980 to 2013, empirically determined the impact of public sector expenditures (CEXP and REXP) together with private sector investment (PINV) on unemployment (UNEMP) in Nigeria. Capital expenditure and private sector investment both in the medium to long-run were found to serve as catalyst towards reduction of unemployment, while recurrent expenditure was not statistically strong enough to do same. The R-2 (0.84) showed that greater proportion of the total variations in UNEMP was brought about by variations in the regressors. Further tests like autocorrelation, hetroscedasticity, specification error, and multicollinearity indicated respectively that there is no presence of autocorrelation hence the model produced a parsimonious result; the variance is constant over time; the link test confirmed by Ramsey reset test suggested there was no specification error; and lastly the variance inflation factor (VIF) of the variables implies that there is no evidence of multicollinearity. The study recommends, inter alia, that the proportion of capital expenditure in Nigerian budget profile should be systematically increased while the recurrent expenditure should be reduced; and there is need to stimulate competition among investors through removal of structural and institutional rigidities and government should design clear policy incentives to private sector investment.
The risk of global financial markets: The case of China in a developing country
Authors: Kum Philemon Nji , Iwu Chux Gervase , Umezurike Samuel Augustine
Published: February 2017

Globalization has forced many countries to rely on one another for products and services which they are unable to source locally. More so, trade is used as the channel to procure those. South Africa and China share very close relations which are boosted by South Africa’s neo-liberal policy, and its membership of the BRICS bloc. Often, this relationship has been subjected to different interpretations leading to the inability to reach a consensus on South Africa’s intention and exact benefits from neo-liberalization and membership of BRICS bloc. On this basis, we affirm that a notable gap exists in scholarly literature which has not provided the full-fledged understanding of the impact of Chinese manufactured goods into South Africa. We draw from the concepts of protectionism and free trade to expatiate the concerns raised by many with respect to the nature and benefits of the relationship. The paper relied extensively on secondary sources of data from which the authors then analyzed, interpreted and drew conclusions to provide a contextual explanation of the phenomenon of Chinese invasion of South African market. This method was useful for two reasons; namely its capacity to generate new insights and secondly, access to comparative studies. While the results show that South African clothing firms are increasingly shutting down because of lower prices from international competitors (especially China), and also due to structural issues of the present South African economy, we are equally aware of the extensive pressure from interest groups for the South African government to protect major local industries such as steel and textile. We argue anyway that the South African government is playing its cards carefully to avoid a backlash, especially considering its position within the BRICS bloc.
Gold sales forecasting: The Box-Jenkins methodology
Authors: Tsoku Johannes Tshepiso , Phukuntsi Nonofo , Metsileng Lebotsa Daniel
Published: February 2017

The study employs the Box-Jenkins Methodology to forecast South African gold sales. For a resource economy like South Africa where metals and minerals account for a high proportion of GDP and export earnings, the decline in gold sales is very disturbing. Box-Jenkins time series technique was used to perform time series analysis of monthly gold sales for the period January 2000 to June 2013 with the following steps: model identification, model estimation, diagnostic checking and forecasting. Furthermore, the prediction accuracy is tested using mean absolute percentage error (MAPE). From the analysis, a seasonal ARIMA(4,1,4)×(0,1,1)12 was found to be the “best fit model” with an MAPE value of 11% indicating that the model is fit to be used to predict or forecast future gold sales for South Africa. In addition, the forecast values show that there will be a decrease in the overall gold sales for the first six months of 2014. It is hoped that the study will help the public and private sectors to understand the gold sales or output scenario and later plan the gold mining activities in South Africa. Furthermore, it is hoped that this research paper has demonstrated the significance of Box-Jenkins technique for this area of research and that they will be applied in the future.

Published: February 2017

OBJECTIVE

Insulin resistance (IR) is a hallmark of obesity and metabolic disease. Circulating extracellular RNAs (ex-RNAs), stable RNA molecules in plasma, may play a role in IR, though most studies on ex-RNAs in IR are small. We sought to characterize the relationship between ex-RNAs and metabolic phenotypes in a large community-based human cohort.

RESEARCH DESIGN AND METHODS

We measured circulating plasma ex-RNAs in 2,317 participants without diabetes in the Framingham Heart Study (FHS) Offspring Cohort at cycle 8 and defined associations between ex-RNAs and IR (measured by circulating insulin level). We measured association between candidate ex-RNAs and markers of adiposity. Sensitivity analyses included individuals with diabetes. In a separate cohort of 90 overweight/obese youth, we measured selected ex-RNAs and metabolites. Biology of candidate microRNAs was investigated in silico.

RESULTS

The mean age of FHS participants was 65.8 years (56% female), with average BMI 27.7 kg/m2; participants in the youth cohort had a mean age of 15.5 years (60% female), with mean BMI 33.8 kg/m2. In age-, sex-, and BMI-adjusted models across 391 ex-RNAs in FHS, 18 ex-RNAs were associated with IR (of which 16 were microRNAs). miR-122 was associated with IR and regional adiposity in adults and IR in children (independent of metabolites). Pathway analysis revealed metabolic regulatory roles for miR-122, including regulation of IR pathways (AMPK, target of rapamycin signaling, and mitogen-activated protein kinase).

CONCLUSIONS

These results provide translational evidence in support of an important role of ex-RNAs as novel circulating factors implicated in IR.
Metodologia de análise da percepção tátil em diferentes classes de materiais e texturas para aplicação no design de produtos
Authors: Dischinger Maria do Carmo Torri , Kindlein Jr Wilson
Published: February 2017

A presente pesquisa foi conduzida objetivando tratar das relações que se estabelecem entre usuário e produto, exploradas através de uma análise de seus elementos compositivos: sentidos, percepção e significação, considerando o viés humano, e materiais, acabamentos e superfície, considerando o objeto. Busca-se contribuir com uma metodologia que possa auxiliar no projeto de produtos e interfaces com parâmetros mais objetivos, respaldando a escolha do designer na transposição do abstrato ao material. Através do estudo de técnicas empregadas na Análise Sensorial de alimentos foi possível derivar uma aplicação customizável para a análise do sentido do tato, fazendo uma referência à importância de comprovar as possibilidades de exploração dentro do aprofundamento em um dos sentidos. Esta metodologia foi esquematizada e aplicada em todas as suas etapas. Para tanto, utilizaram-se equipamentos de medição, uma equipe de julgadores treinados e pessoas aleatórias para obter medidas objetivas, subjetivas e afetivas. Exploram-se as possibilidades decorrentes do uso de equipamentos tecnológicos, do treinamento científico de julgadores e a interface mais subjetiva, do afeto, que enfatiza o usuário como foco do design. Tal encontro evidencia caminhos possíveis para uma projetação mais abrangente, mais coerente com o que se deseja transmitir e quem se deseja alcançar.

Ambiente virtual de aprendizagem para ensino de costura: um estudo fundado nas concepções intersubjetivas do conhecimento
Authors: Guimarães Elisangela Manarim , Morgenstern Elenir Carmem
Published: February 2017

O presente artigo, resultado de pesquisa de Mestrado Profissional em Design/UNIVILLE, apresenta possibilidades de ampliação do ensino de costura, por intermédio de ambiente virtual de aprendizagem (AVA), conjeturando acesso ao aprendizado de costura à estudantes do Curso Técnico de Produção e Design de Moda do Instituto Federal de Educação, Ciência e Tecnologia de Santa Catarina (IFSC) do Campus Jaraguá do Sul (SC). A relevância da pesquisa encontra-se na observação da carência de profissionais no setor de confecção, mais especificamente da costura, na falta de qualificação desses profissionais e no desinteresse por essa atividade. Entende-se que, mediante o desenvolvimento de uma plataforma de ensino a distância (EAD), os estudantes não necessitarão exclusivamente posicionar-se perante uma máquina para aprender técnicas e processos da costura, pois terão acesso, por meio de propostas interativas, a um conhecimento coletivo, possibilitado pelo ciberespaço, formador de uma inteligência coletiva. Focalizando as concepções intersubjetivas do conhecimento, trazendo como base teórica a hermenêutica e a dialética, apresentam-se, neste artigo, possibilidades intersubjetivas para a aprendizagem de costura a distância por meio do desenvolvimento de AVA que congregará games de costura, nos quais simular-se-ão montagem de partes de peças do vestuário.  O jogo, configurado a partir de diretrizes resultantes de investigação teórica, intenta ampliar possibilidades de acesso a saberes relacionados a questões técnicas de costura, por intermédio de processos intersubjetivos de aprendizagem.
Ver, compreender e aprender: estudo comparado com guias de uso de apps editoriais para dispositivos móveis
Authors: Dalagnoli Ana Claudia , Dos Santos Flávio Anthero Nunes Vianna
Published: February 2017

Este estudo foi construído a partir da percepção de que a evolução das tecnologias e, sobretudo, o aprimoramento da comunicação em dispositivos móveis, impacta diretamente no processo de desenvolvimento de aplicativos (apps) e softwares e na relação do ser humano com as novas interfaces. A pesquisa apresenta uma análise comparativa entre os aplicativos para iPad das revistas de decoração e design de interiores Casa Claudia (Editora Abril) e Casa e Jardim (Editora Globo), a partir de testes de usabilidade dos mesmos em tablets Apple. O objetivo foi verificar se os guias de uso disponíveis em aplicativos (apps) de revistas para dispositivos móveis, construídos por textos e imagens, estão cumprindo a função de comunicar, efetivamente, o modo de uso desses apps. As informações foram coletadas junto a mulheres com idade entre 25 e 54 anos que testaram e comentaram o funcionamento das versões atuais dos apps. Foram selecionadas 24 mulheres para fazerem atividades individuais monitoradas em ambos os apps, com dados coletados por meio de observações e think aloud. Os dados obtidos foram analisados, e com base nos resultados foi proposto um ajuste nos requisitos para o desenvolvimento de interfaces de guias para aplicativos com vistas à maior satisfação das usuárias. Foram percebidas falhas severas na apreensão e aplicação das orientações disponíveis nos guias de uso. Os pesquisadores verificaram que os requisitos básicos para aumentar a satisfação e melhorar a usabilidade estão relacionados à facilidade de compreensão e à simplicidade no uso, o que pode ser obtido por meio de melhorias relacionadas à aplicação da tecnologia, ao conhecimento dos processos cognitivos dos usuários e à aplicação de conceitos semióticos de comunicação. O estudo pode servir de base para o desenvolvimento e análise de guias de uso de outros apps com características similares, em diversos sistemas operacionai

Since early November 2016, the number of laboratory-confirmed norovirus infections reported in Germany has been increasing steeply. Here, we report the detection and genetic characterisation of an emerging norovirus recombinant, GII.P16-GII.2. This strain was frequently identified as the cause of sporadic cases as well as outbreaks in nine federal states of Germany. Our findings suggest that the emergence of GII.P16-GII.2 contributed to rising case numbers of norovirus gastroenteritis in Germany.
God's Moral Obligation to Hide
Authors: Gerrie James Brian
Published: February 2017

The following is a response to J.L. Schellenberg's argument from the fact of divine hiddenness for unbelief in God. If God is capable of making a vast number of distinct universes, then God might be justified in allowing universes to exist that are fundamentally natural in how they can appear to a great many sentient beings in those universes. A reductio ad absurdum argument is presented, based on the assumption of the moral principle that it is wrong for God, or anyone else, to allow universes to exist that are ambiguous in regard to the question of whether they are naturally or divinely originated. Adopting such a principle implies that one must either contradictorily assert that we cannot know God's existence, or that we have a moral obligation to prevent the continuation of sentient life in this universe by any ethical means available.
What Has the University of Toronto to Do with the Toronto School of Theology? A Postliberal Approach
Authors: Graham David A.
Published: February 2017

This article explores the relationship between the contemporary Western university and Christian theological studies from a postliberal perspective. First, it highlights the manner in which the Toronto School of Theology has construed theology within its new conjoint PhD program. Second, it analyzes Hans Frei's typology of modern theology, focusing on the variety of ways in which theology as such incorporates non-theological disciplines. Third, it locates theological studies as defined by the Toronto School of Theology within two categories that appear in Frei's typology. Fourth, it explores the nature of the contemporary Western university, both postmodern ideological trajectories and the functional residue of modernity. Finally, it argues that the metaphor of “conjoining” represents an apt proposal for the relationship of theology to the university, in particular the intellectual activity undertaken within the Toronto School of Theology and what occurs within the University of Toronto.

The objectives of this study were to evaluate the effects of pavement surface type, tack coat material, and application rate on the interface bond strength between a hot-mix asphalt overlay and underlying pavement layers in the field. The effects of interface bonding on short-term pavement performance were also investigated. Three field projects that included 14 in-service test sections were constructed with four types of emulsified tack coats applied at different residual application rates. Specimens were cored from the test sections, and the interface shear strength (ISS) was measured at different service times with a direct shear test device, the Louisiana interlayer shear strength tester. The results of the study showed that, with respect to surface type, the ISS was largely dependent on the type of pavement surface receiving tack coat materials and surface texture. With respect to tack coat material type, the use of a nontracking (rapidly setting) tack coat resulted in a greater ISS than the use of slowly setting (SS-1 and SS-1H) tack coats, a result that was primarily attributed to the stiffer base asphalt cement used in the nontracking tack coat material. With respect to the effects of service time, the interface bonding strength increased with service time in all field projects and for all surface types. This phenomenon was primarily attributed to tack coat curing, which was more pronounced with slowly setting tack coat materials. Laboratory ISS test results correlated well with short-term field performance. All test sections except those that did not meet the minimum ISS threshold of 40 psi, recommended by NCHRP Project 9-40, exhibited satisfactory cracking performance.

OBJECTIVE

Patients with ventriculoperitoneal (VP) shunts with programmable valves who would benefit from osseointegrated hearing devices (OIHDs) represent a unique population. The aim of this study was to evaluate the magnetic field strengths of 4 OIHDs and their interactions with 5 programmable VP shunt valves.

METHODS

Magnetic field strength was measured as a function of distance for each hearing device (Cochlear Baha 5, Cochlear Baha BP110, Oticon Ponto Plus Power, and Medtronic Sophono) in the following modes: inactive, active in quiet, and active in 60 decibels of background noise in the sound booth. The hearing devices were introduced to each shunt valve (Aesculap proGAV, Aesculap proGAV 2.0, Codman Hakim, Codman Certas, and Medtronic Strata II) also as a function of distance in these identical 3 settings. Each trial was repeated 5 times. Between each trial, the valves were assessed for a change in setting. Finally, using a skull model, the devices were introduced to each other in standard anatomical locations and the valves were assessed for a change in settings.

RESULTS

The maximum magnetic field strengths generated by the Cochlear Baha 5, BP110, and Oticon OIHDs were 1.1, 36.2, and 48.7 gauss (G), respectively. The maximum strength generated by the Sophono device was > 800 G. The magnetic field strength of the hearing devices decreased markedly with increasing distance from the device. The strength of the Sophono's magnetic attachment decreased to 34.8 G at 5 mm. The Codman Hakim, Codman Certas, and Medtronic Strata II valve settings changed when rotating the valves next to the Sophono abutment. No other changes in valve settings occurred in the distance or anatomical models for any other trials.

CONCLUSIONS

This is the first study evaluating the interaction between OIHDs and programmable VP shunt valves. The findings suggest that it is safe to use these devices together without having to switch to a nonprogrammable valve or move the shunt valve to a more distant location. Still, care should be taken if the Sophono device is used to ensure that the valve is ≥ 5 mm away from the magnetic attachment.

OBJECTIVE

Fusiform cerebral aneurysms represent a small portion of intracranial aneurysms; differ in natural history, anatomy, and pathology; and can be difficult to treat compared with saccular aneurysms. The purpose of this study was to examine the techniques of treatment of ruptured and unruptured fusiform intracranial aneurysms and patient outcomes.

METHODS

In 45 patients with fusiform aneurysms, the authors retrospectively reviewed the presentation, location, and shape of the aneurysm; the microsurgical technique; the outcome at discharge and last follow-up; and the change in the aneurysm at last angiographic follow-up.

RESULTS

Overall, 48 fusiform aneurysms were treated in 45 patients (18 male, 27 female) with a mean age of 49 years (median 51 years; range 6 months–76 years). Twelve patients (27%) had ruptured aneurysms and 33 (73%) had unruptured aneurysms. The mean aneurysm size was 8.9 mm (range 6–28 mm). The aneurysms were treated by clip reconstruction (n = 22 [46%]), clip-wrapping (n = 18 [38%]), and vascular bypass (n = 8 [17%]). The mean (SD) hospital stay was 19.0 ± 7.4 days for the 12 patients with subarachnoid hemorrhage and 7.0 ± 5.6 days for the 33 patients with unruptured aneurysms. The mean follow-up was 38.7 ± 29.5 months (median 36 months; range 6–96 months). The mean Glasgow Outcome Scale score for the 12 patients with subarachnoid hemorrhage was 3.9; for the 33 patients with unruptured aneurysms, it was 4.8. No rehemorrhages occurred during follow-up. The overall annual risk of recurrence was 2% and that of rehemorrhage was 0%.

CONCLUSIONS

Fusiform and dolichoectatic aneurysms involving the entire vessel wall must be investigated individually. Although some of these aneurysms may be amenable to primary clipping and clip reconstruction, these complex lesions often require alternative microsurgical and endovascular treatment. These techniques can be performed with acceptable morbidity and mortality rates and with low rates of early rebleeding and recurrence.

Published: February 2017

The field of Alzheimer’s disease (AD) research has grown exponentially over the past few decades, especially since the isolation and identification of amyloid-β from postmortem examination of the brains of AD patients. Recently, the Journal of Alzheimer’ s Disease (JAD) put forth approximately 300 research reports which were deemed to be the most influential research reports in the field of AD since 2010. JAD readers were asked to vote on these most influential reports. In this 3-part review, we review the results of the 300 most influential AD research reports to provide JAD readers with a readily accessible, yet comprehensive review of the state of contemporary research. Notably, this multi-part review identifies the “hottest” fields of AD research providing guidance for both senior investigators as well as investigators new to the field on what is the most pressing fields within AD research. Part 1 of this review covers pathogenesis, both on a molecular and macro scale. Part 2 review genetics and epidemiology, and part 3 covers diagnosis and treatment. This part of the review, pathology, reviews amyloid-β, tau, prions, brain structure, and functional changes with AD and the neuroimmune response of AD.

Background: The association of central arterial stiffness and pressure pulsatility with mild cognitive impairment (MCI) and dementia is not well characterized in the population-based setting.

Objective: The aim of this study was to quantify the cross-sectional association of arterial stiffness and pressure pulsatility with MCI and dementia among 4,461 older white and black adults from the population-based Atherosclerosis Risk in Communities Study-Neurocognitive Study.

Methods: We used race-stratified multinomial logistic regression to evaluate associations of percentile cut points of carotid-femoral pulse wave velocity, central systolic blood pressure, central pulse pressure, and pulse pressure amplification with MCI and dementia versus no cognitive impairment.

Results: Among whites, those with carotid-femoral pulse wave velocity or central systolic blood pressure ≥75th percentile had a higher prevalence of MCI compared to participants <75th percentile (conditional odds ratio (OR); 95% confidence interval (CI): 1.27 (1.02, 1.56) and 1.28 (1.04, 1.57), respectively) and those with central pulse pressure ≥75th percentile had a higher prevalence of MCI (OR 1.27 (95% CI: 1.03, 1.58)) and dementia (OR 1.76 (95% CI: 1.06, 2.92) compared to participants <75th percentile. Also among whites, those with pulse pressure amplification ≤25th percentile had a higher prevalence of dementia compared to participants >25th percentile (OR 1.65; (95% CI: 1.01, 2.70). Weaker associations were seen among black participants.

Conclusion: Higher arterial stiffness and pulsatility were associated with MCI and dementia in white participants. Longitudinal characterization of the observed associations is warranted to assess whether arterial stiffness and pressure pulsatility predict MCI and dementia among older adults.
