The aim of the present study was to compare assessments of sperm concentration and sperm motility analysed by conventional semen analysis with those obtained by computer-assisted semen analysis （CASA）（Copenhagen Rigshospitalet Image House Sperm motility Analysis System （CRISmAS） 4.6 software） using semen samples from 166 young Danish men. The CRISmAS software identifies sperm concentration and classifies spermatozoa into three motility categories. To enable comparison of the two methods, the four motility stages obtained by conventional semen analysis were, based on their velocity classifications, divided into three stages, comparable to the three CRISmAS motility categories： rapidly progressive （A）, slowly progressive （B） and non-progressive （C＋ D）. Differences between the two methods were large for all investigated parameters （P〈0.001）. CRISmAS overestimated sperm concentration and the proportion of rapidly progressive spermatozoa and, consequently, underestimated the percentages of slowly progressive and non-progressive spermatozoa, compared to the conventional method. To investigate whether results drifted according to time of semen analysis, results were pooled into quarters according to date of semen analysis. CRISmAS motility results appeared more stable over time compared to the conventional analysis; however, neither method showed any trends. Apparently, CRISmAS CASA results and results from the conventional method were not comparable with respect to sperm concentration and motility analysis. This needs to be accounted for in clinics using this software and in studies of determinants of these semen characteristics.

Recovery of carbon monoxide from flue gases by reactive absorption in ionic liquid imidazolium chlorocuprate(I): mass transfer coefficients

引用

Chinese Journal of Chemical Engineering 2015年第5期23卷 769-774页

作者： Gabriel Zarca Inmaculada Ortiz ane Urtiaga Department of Chemical and Biomolecular Engineering Universidad de Cantabria Av. Los Castros s/n.

Recovery of carbon monoxide from flue gases by selective absorption of carbon monoxide in an imidazolium chlorocuprate（l） ionic liquid is considered in this work as an alternative to the use of molecular volatile solvents such as aromatic hydrocarbons. The present work evaluates the CO mass transfer rates from the gas phase to the ionic liquid solutions in the absence of chemical reaction. To that end, carbon dioxide was employed as an inert model gas and absorption experiments were performed to assess the influence of different process variables in a batch reactor with fiat gas-liquid interface. The experimental mass transfer coefficients showed significant var- iation with temperature, （3.4-10.9） × 10^-7 m·s^-1 between 293 and 313 K; stirring speed, （10.2- 33.1）× 10^-7 m.s 1 between 100 and 300 r·min^-1; and concentration of copper（1）, （6.6-10.2） × 10^-7 m·s^-1 between 0.25 and 2 mol· L^- 1. In addition, the mass transfer coefficients were eventually found to follow a poten- tial proportionality of the type kL ∝μ^-0.5 and the dimensionless correlation that makes the estimation of the mass transfer coefficients possible in the studied range of process variables was obtained： Sh=10^-2.64 Re^1.07 , Sc^0.75,These results constitute the first step in the kinetic analysis of the reaction between CO and imidazolium chlorocuprate（I） ionic liquid that determines the design of the separation units.

Characterisation of Na-metasomatism in the Sveconorwegian Bamble Sector of South Norway

引用

Geoscience Frontiers 2014年第5期5卷 659-672页

作者： ane K.Engvika Peter m.Ihlena Hakon Austrheimb Geological Survey of Norway.P.O.Box 6315 Sluppen.N-7491 TrondheimNorway Department of Geosciences.University of Oslo P.O.Box 1047 BlindernN-0316 OsloNorway

Na-metasomatism in the form of albitisation is regionally extensive in the Precambrian crust of southern Scandinavia and is particularly widespread in the Bamble Sector, the Kongsberg-modum Sector and the Norwegian part of the mylonite Zone. Sites of albitisation outside these belts are associated with hy- drothermal breccia pipes and fracture-bound alteration. The albitites are composed of near end-member sodic plagioclase （Ano 5Ab94-99） with minor carbonate （calcite and dolomite）, rutile, clinopyroxene （En30Fs21-23W047 49）, amphibole （edenite-pargasite）, quartz, titanite, tourmaline, epidote （Fe3＋ - 0.20 -0.85 a.p.f.u） and chlorite （mg# = 0.81-0.89）. The albitites have been studied in detail in the region around the town of Kragem, and are described as albitisation along veins, as breccias, alhitic felsites, massive carbonate-bearing albitites and megascale clinopyroxene-titanite-bearing albitite. The strong fluid control on their formation is illustrated by the veining and mineral replacement reactions, showing fluid transport by a H20-CO2 fluid rich in Na, depleting Fe and mg from the host rock, in accordance with calculated mass transfer. A study of the mineralogical replacement reactions in combination with a regional compilation has demonstrated the relationship between metasomatic processes and the for- mation of apatite, ruti｜e and Fe deposits. The albitites occur spatially associated with other metasomatic rocks such as scapolitised metagabbros. We document that metasomatism is an important mineral- and rock-forming process in the continental crust, which in the Bamble Sector is a part of the tectonome- tamorphic evolution of the Sveconorwegian orogen.

Background: Built environments that are designed to provide accessible, attractive, and convenient locales promote regular physical activity(PA).Norway has great variability in its geographic, natural, and built environment features. Urban areas have well-developed built environment features, whereas the rural areas are less walkable and this may influence the mode of transport. In general, active transport is more common in urban centers. Further, public transportation is more developed in urban areas, whereas motorized transport may be more widespread in the rural areas. Despite this, in Sogn & Fjordane, a rural county in western Norway, high PA levels are frequently observed. Thus, the aims of this study were to(1) explore perceived built environment features and characterize their associations with objectively measured PA levels in Norwegian adults and(2) explore the differences in these correlates between Sogn & Fjordane and the rest of ***: In this cross-sectional study, participants used questionnaires to rate perceptions of their built environments, and their PA was objectively measured for 7 consecutive days using the Acti Graph GT1 m accelerometer. There were 972 Norwegian adults who were included in the study. The average age was 46.9 ± 6.5 years and 43.8% of participants were men. Data were analyzed using multiple linear ***: Total PA and moderate-to-vigorous physical activity(mVPA) were both associated with perceived walkability, the community perception score, and active transport for commuting(all p ≤ 0.004). We also observed geographic-area-specific associations: the community perception score was negatively associated with total PA and mVPA in the rest of Norway(p ≤ 0.012) but not in Sogn & Fjordane. Public transport for commuting was positively associated with mVPA in Sogn & Fjordane(p = 0.03) but not in the rest of ***: Total PA level and mVPA were associated with built environment factors, such as perceptio

引用

Open Journal of Ophthalmology 2012年第4期2卷 119-121页

作者： José Andonegui José Ramón maya ane Zurutuza mónica Pérez de Arcelus Ophthalmology Department Complejo Hospitalario de Navarra Pamplona Spain

Purpose: To describe the clinical, angiographic, and Optical Coherence Tomography (OCT) findings in a patient with Unilateral Acute Idiopathic maculopathy (UAIm) and to discuss a possible pattern of OCT findings in patients with this disease. methods: Case report. Results: A 34-year-old man with UAIm was evaluated. During the acute phase fundus examination revealed a yellow thickening in the macular area of the right eye, Fluorescein Angiography (FA) showed early alternating patches of hypofluorescence and hyperfluorescence and late hyperfluorescence and OCT showed thickening of the outer retina in the foveal zone. Six weeks later, the macula had pigmentary mottling, FA showed an area of central hypofluorescence surrounded by a hyperfluorescent ring that remained unchanged during the angiogram and the OCT examination was normal. Conclusion: OCT is a useful diagnostic tool for UAIm. OCT evaluation of patients with this disease will exhibit the heterogeneous hyperreflectivity and thickening of the outer retina and Retinal Pigment Epithelium (RPE). A serous macular detachment may not be a prominent finding in UAIm.

在成年大脑中,活动依赖性髓鞘可塑性是正确学习和记忆巩固所必需的。因此,髓鞘的丢失、改变,甚至细微的结构变更都会损害神经网络活动,导致功能障碍。在多发性硬化症中,虽然自发的髓鞘修复过程是可能的,但患者之间存在异质性。髓鞘修复有时会导致功能恢复,这通常在运动水平比在认知水平更明显。在铜宗处理的小鼠模型中,大量脑脱髓鞘随后发生自发且强烈的髓鞘再生。然而,重组髓鞘虽然具有功能,但可能不会表现出与发育髓鞘相同的形态特征,这可能会对神经网络的活动产生影响。基于此,本研究使用铜腙处理的小鼠模型来分析短暂性脱髓鞘对脑结构、功能和认知的长期影响。本研究结果表明,尽管脱鞘事件后存在髓鞘再生,但仍会导致长期认知障碍,例如空间工作记忆、社交记忆、认知灵活性和多动症的缺陷。这些缺陷与内侧前额叶皮质(m PFC)和海马体(HPC)髓鞘含量的减少以及结构髓鞘修饰有关,表明这些结构中的髓鞘再生过程可能不完善。在体电生理记录表明,脱髓鞘事件改变了HPC-mPFC活动的同步性,这对于记忆过程至关重要。总而言之,本研究数据表明,短暂脱髓鞘后的髓鞘修复过程不允许完全恢复皮质结构中的初始髓鞘特性。这些细微的变更改变了神经网络特征并导致小鼠长期认知缺陷。
