The presence of thrust-block naled after a major surge event: Kuannersuit Glacier, West Greenland

Abstract Thrust-block naled in front of Kuannersuit Glacier, West Greenland, appears to have formed during the termination of a terrestrial surge event by a combination of enhanced winter runoff, rapid advance of the glacier terminus, and proglacial stress release by thrusting and stacking of naled blocks. This process is equivalent to the formation of thrust-block moraines. The thrust-block naled consists of at least seven thrust sheets, which are characterized by stratified ice with beds composed of a lower debris-rich lamina, an intermediate dispersed lamina and a top clean-ice lamina, and underlain by frozen outwash deposits. The thrust-block naled differs from basal stratified ice in the absence of internal deformation structures, a relatively low debris concentration, a clay-rich particle-size distribution and a preferential sorting of lighter minerals. The oxygen isotope composition of the thrust-block naled is indistinguishable from δ18O values from meteoric glacier ice and bulk meltwater, but different from basal stratified ice facies. The d–δD relationship indicates that thrust-block naled has been formed by freezing of successive thin layers of bulk waters with variable isotopic composition, whereas basal stratified ice has developed in a subglacial environment with regelation. This work shows that the association between proglacial naled and rapidly advancing glaciers may have significant consequences for the proglacial geomorphology and the interpretation of basal ice layers.
Cutaneous water loss and lipids of the stratum corneum in house sparrows Passer domesticus from arid and mesic environments

SUMMARY Birds that live in hot, dry environments must balance water intake with losses in order to maintain water homeostasis. The outer layer of the integument, called the stratum corneum (SC), consists of corneocytes embedded in a matrix of lipids. The SC serves as a barrier to water vapor diffusion through the skin. We measured cutaneous water loss (CWL) in two populations of house sparrow Passer domesticus L. , one living in a desert environment in Saudi Arabia, and another living in a mesic environment in Ohio, USA. We found that CWL rates at 30°C were lower in desert individuals (11.9±2.2 mg H2O cm-2 day-1; N=11) than in mesic birds (16.0±2.6 mg H2O cm-2 day-1; N=14). We hypothesized that changes in the lipid composition of the SC could affect CWL. We analyzed four classes of lipids in the SC: ceramides, cerebrosides, cholesterol and free fatty acids, by thin layer chromatography. Compared to mesic sparrows, desert birds had a higher amount of ceramides (49.2±10.3 mg g-1 SC dry mass in Saudi Arabia; 38.2±18.0 mg g-1 SC dry mass in Ohio) and cerebrosides (101.2±48.9 mg g-1 SC dry mass in Saudi Arabia; 56.5±34.0 mg g-1 SC dry mass in Ohio), and a lower percentage of cholesterol (4.1±3.6% in Saudi Arabia; 5.4±2.5% in Ohio) in their SC. Although CWL was lower in sparrows from Arabia, and lipid composition of their SC differed, we could not detect differences between rates of water loss through non-living skin attached to glass vials (46.0±15.7 mg H2O cm-2 day-1 for sparrows in Saudi Arabia; 45.8±27.2 mg H2O cm-2 day-1 for sparrows in Ohio). These results suggest that biological control mechanisms interact with layers of lipids in the stratum corneum to adjust CWL to the environment.
Contraceptive technologies: Responding to womens needs.

Seven out of 10 women in Sub-Saharan Africa South Central Asia and Southeast Asia who want to avoid pregnancy but are not using modern contraceptives report reasons for nonuse that indicate currently available methods do not satisfy their needs according to new Guttmacher research. The study found that overcoming method-related reasons for contraceptive nonuse could reduce unintended pregnancy by as much as 59% in these regions and that increased investment in the development of new methods that better address women’s concerns is needed.
Occurrence and Transformation Reactions of Chiral and Achiral Phenoxyalkanoic Acid Herbicides in Lakes and Rivers in Switzerland

The occurrence of chiral and achiral phenoxyalkanoic acid herbicides in lakes and rivers in Switzerland is reported. The compounds most frequently detected were the chiral 2-(4-chloro-2-methylphenoxy)propionic acid (mecoprop, MCPP) and the achiral 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D), and dicamba, a benzoic acid derivative. The compounds were generally present at concentrations well below the ECE recommended drinking water tolerance level (100 ng/L), even in lakes situated in areas with intense agricultural activities. The chiral 2-(2,4-dichlorophenoxy)propionic acid (dichlorprop, DCPP) was hardly present, and none of the compounds was detected in mountain lakes. In case of MCPP, both enantiomers (R and S) were present, although only the technical material with the R enantiomer (mecoprop-P) is registered and used as a herbicide in Switzerland. Previous studies indicated significant enantiomerization of MCPP and DCPP in soil leading to residues enriched in R en.

Increased risk of HPV-associated genital cancers in men and women as a consequence of 1 pre-invasive disease 2

44 To assess the excess risk of HPV-associated cancer (HPVaC) in two at-risk groups – women with a previous 45 diagnosis of high grade cervical intraepithelial neoplasia (CIN3) and both men and women treated for non- 46 cervical pre-invasive ano-genital disease. 47 All CIN3 cases diagnosed in 1989-2015 in Scotland were extracted from the Scottish cancer registry (SMR06). All 48 cases of pre-invasive penile, anal, vulval, and vaginal disease diagnosed in 1990-2015 were identified within the 49 NHS pathology databases in the two largest NHS health boards in Scotland. Both were linked to SMR06 to extract 50 subsequent incidence of HPVaC following the diagnosis of CIN3 or pre-invasive disease. Standardised incidence 51 ratios were calculated for the risk of acquiring HPVaC for the two at-risk groups compared with the general 52 Scottish population. 53 Among 69714 females in Scotland diagnosed with CIN3 (890360.9 person-years), 179 developed non-cervical 54 HPVaC. CIN3 cases were at 3.2-fold (95% CI: 2.7 to 3.7) increased risk of developing non-cervical HPVaC, 55 compared to the general female population. Among 1235 patients diagnosed with non-cervical pre-invasive 56 disease (9667.4 person-years), 47 developed HPVaC. Individuals with non-cervical pre-invasive disease had a 57 substantially increased risk of developing HPVaC - 15.5-fold (95% CI: 11.1 to 21.1) increased risk for females and 58 28-fold (11.3 to 57.7) increased risk for males. We report a significant additional risk of HPV-associated cancer in those have been diagnosed with pre-invasive HPV-associated lesions including but not confined to the cervix. Uncovering the natural history of pre-invasive disease has potential for determining screening, prevention and treatment.

Investigations of the speciation of phosphorus in coastal and estuarine waters of the Great Barrier Reef, using iron strips and colorimetry

A new method of determining phosphorus in sea water, using iron-impregnated strips of filter paper, was investigated and compared with standard colorimetric methods of phosphorus analysis. Laboratory experiments were undertaken to determine the number of iron strips required to extract phosphorus from sea water, the length of time a strip needed to adsorb all P from solution, the reproducibility of the method, and whether the strips could measure P adsorbed to different particles. Field studies were carried out with iron strips in Cleveland Bay and the Herbert estuary, and comparisons were made with concentrations of dissolved, particulate and organic phosphorus determined by standard techniques. The iron-strip method was shown to work well under laboratory conditions, but the field studies showed varying results for the different environments tested. Generally, most of the dissolved inorganic phosphorus present in sea water was taken up by the strips. The iron strips also took up a proportion of other phosphorus fractions in sea water, but the nature of this uptake appears to vary with environmental conditions.
The MRi-Share database: brain imaging in a cross-sectional cohort of 1,870 university students

We report on MRi-Share, a multi-modal brain MRI database acquired in a unique sample of 1,870 young healthy adults, aged 18 to 35 years, while undergoing university-level education. MRi-Share contains structural (T1 and FLAIR), diffusion (multispectral), susceptibility weighted (SWI), and resting-state functional imaging modalities. Here, we described the contents of these different neuroimaging datasets and the processing pipelines used to derive brain phenotypes, as well as how quality control was assessed. In addition, we present preliminary results on associations of some of these brain image-derived phenotypes at the whole brain level with both age and sex, in the subsample of 1,722 individuals aged less than 26 years. We demonstrate that the post-adolescence period is characterized by changes in both structural and microstructural brain phenotypes. Grey matter cortical thickness, surface area and volume were found to decrease with age, while white matter volume shows increase. Diffusivity, either radial or axial, was found to robustly decrease with age whereas fractional anisotropy only slightly increased. As for the neurite orientation dispersion and densities, both were found to increase with age. The isotropic volume fraction also showed a slight increase with age. These preliminary findings emphasize the complexity of changes in brain structure and function occurring in this critical period at the interface of late maturation and early aging.
Glycogen Synthase Kinase-3β Inhibitors Prevent Cellular Polyglutamine Toxicity Caused by the Huntington's Disease Mutation*

Huntington's disease is one of nine known neurodegenerative disorders caused by an expanded polyglutamine (poly(Q)) tract in the disease protein. These diseases are associated with intraneuronal protein aggregates. Heat-inducible chaperones like HSP70 and HSP27 suppress poly(Q) aggregation and/or toxicity/cell death. Heat shock transcription factors, including HSF-1, regulate HSP70 and HSP27 expression. HSF-1 activity is reduced by glycogen synthase kinase-3 (GSK-3) and enhanced by GSK-3 inhibitors, like lithium. Thus, we hypothesized that lithium treatment may partially rescue death in Huntington's disease cell models. LiCl reduced poly(Q) toxicity in neuronal and nonneuronal cell lines, but this was not associated with elevation of HSP70 or HSP27. The protective effect of lithium involved GSK-3β inhibition, since poly(Q) toxicity was also reduced by SB216763, a GSK-3β inhibitor, and by overexpression of a dominant-negative GSK-3β mutant. LiCl and SB216763 increased β-catenin-dependent T-cell factor-mediated transcription. Since β-catenin overexpression protected cells from poly(Q) toxicity, we tested whether this pathway was impaired by a poly(Q) expansion mutation. Cells expressing expanded repeats had reduced β-catenin levels associated with a parallel decrease in T-cell factor-mediated transcription, compared with cells expressing wild type constructs. Since LiCl can protect against polyglutamine toxicity in cell lines, it is an excellent candidate for further in vivo therapeutic trials.
Magnetic Sensors for Navigation Applications: An Overview

This paper reviews currently existing electronic magnetic sensor technologies for navigation applications. Magnetic compasses have been used in navigation for centuries. The Earth's geomagnetic field is considered to provide accurate, reliable and economically available information for orientation. Meanwhile, modern magnetometers and compass calibration technologies have allowed the electronic compass to become a crucial navigation tool, even in times of modern satellite navigation using Global Navigation Satellite Systems (GNSS). Magnetic sensor technologies, error modelling and compensating approaches have been reviewed in this paper. Current trends and the outlook for future development of the electronic compass are analysed.
Catheter Ablation of Arrhythmias Originating From the Left Ventricular Out ﬂ ow Tract

The left ventricular out ﬂ ow tract (LVOT) is a frequent source of arrhythmias in patients with and without structural heart disease. An understanding of the anatomic relationship between the aortic valvar lea ﬂ ets and their supporting sinuses, coronary vessels, pulmonary arterial root, right ventricular out ﬂ ow tract, and LVOT is essential for successful treatment of arrhythmias arising from this region. The juxtaposition of aortic valvar lea ﬂ et insertion into the aortic root and the crescents of myocardial tissue incorporated within the aortic sinuses of Valsalva has implications for mapping and ablation above and below the aortic valve lea ﬂ ets. The presence of epicardial fat, coronary arteries, and prominent myocardium in the anteroseptal aspect of the LVOT can present unique challenges for targeting LV summit and intramural ventricular arrhythmias. Advances in ablation techniques that achieve deeper transmural lesions, combined with the knowledge of the complex LVOT anatomy and its adjoining structures, have increased success rates in targeting challenging LVOT arrhythmias.

The prospects for establishing synchroneity in the early postglacial pollen peak of Juniperus in the British Isles

Tipping, Richard M. 1987 06 01: The prospects for establishing synchroneity in the early postglacial pollen peak of Juniperus in the British Isles. Boreas, Vol. 16, pp. 155–163. Oslo. ISSN 0300–9483. Seventy radiocarbon assays on the early postglacial Juniperus pollen peak in the British Isles are collated in order to test the hypothesis that the expansion of Juniperus was synchronous in the British Isles. The necessity of screening this data base is discussed, as are the screening procedures adopted. A number of problems concerned with screening are highlighted, which are related to the paucity of information available from which to assess the reliability of a date. The accepted radiocarbon dates are analysed by computer-generated histograms. No clear pattern of synchroneity is found. The possibility of a diachronous distribution across the British Isles is examined. The methods employed in this study illustrate the problems of using large samples of radiocarbon dates, and exemplify the stringent procedures required in handling such data.
Surface changes in solar irradiance due to aerosols over central Himalayas

During a comprehensive aerosol field campaign as a part of the ISRO‐GBP, extensive measurements of radiative fluxes at the surface were made during December 2004 at Manora Peak, in the Shivalik ranges of the Central Himalayas. The surface radiative fluxes were used to estimate aerosol radiative forcing. Our analysis clearly shows that during the clean atmospheric conditions over Manora Peak, the observed aerosol radiative forcing is in good agreement to those of modeled ones, while for the higher aerosol optical depths (AODs), modeled values are significantly smaller than the observed ones. It was observed that at Manora Peak, the anthropogenic aerosols (from valley below) transported upwards by evolution of boundary layer during the daytime provide an atmosphere conducive for ‘mixed’ aerosols. Focused efforts are needed to address this issue for which simultaneous observations at high altitude site with those in nearby valley are essential.
Association of Longitudinal Changes in Left Ventricular Structure and Function with Myocardial Fibrosis the Multi-ethnic Study of Atherosclerosis Study Methods Population Characteristics Cardiac Magnetic Resonance Statistical Analysis Venkatesh Et Al Association of Lv Structure/function with Fibrosi

L eft ventricular (LV) structural and functional changes in response to, or in association with, myocardial fibrosis are important components of cardiac disease. Myocardial fibro-sis is considered as 1 of the chief factors that influence the process of cardiac remodeling, 1,2 conceptualized as the structural and functional cardiac alterations that accompany exposure to pathogenic processes and cardiovascular risk factors. 3 Previous studies have shown the association of myocardial fibrosis with alterations of myocardial structure and function, as well as with indices of impaired myocardial tissue deformation in varied cardiomyopathies. Sex dependency of these alterations of structure and function has also been demonstrated , 8 reflecting different mechanisms of cardiac morbidity and associated LV remodeling. Cardiac magnetic resonance (CMR) imaging can be used to quantify LV mass and volume accurately throughout the cardiac cycle and is considered as the standard of reference for assessment of structure and function. CMR has also been used to characterize focal and diffuse myocardial fibrosis through late gadolinium enhancement (LGE) and longitudinal relaxation time (T1) mapping, respectively. In previous studies, T1 mapping times and related parameters have been shown to correlate well with collagen content of the myocardium as measured through biopsy, 9,10 whereas LGE has long been used to measure replacement myocardial fibrosis. 11 The goals of this study were to understand how LV structure and function and its 10-year change relate to diffuse and replacement myocardial fibrosis measured at the end of the follow-up period in a multiethnic population. We relate CMR measures Abstract—The association of longitudinal changes in left ventricular (LV) structure and function with myocardial fibrosis is unclear. We relate temporal changes in body size–indexed LV mass (LVMi) and end-diastolic volume indexed to body surface area , LV mass-to-volume ratio, and LV ejection fraction (LVEF) from cine cardiac magnetic resonance for 10 years, with replacement scar assessed from late gadolinium enhancement, and lower postcontrast T1 times reflecting greater diffuse myocardial fibrosis measured at the end of the follow-up period. All participants (n=1813) who underwent cardiac magnetic resonance twice as part of the Multi-Ethnic Study of Atherosclerosis 10 years apart were included. Multivariable logistic and linear regression models adjusted for cardiovascular risk factors measured the association of 10-year changes in LV structure and function, with fibrosis measured at follow-up. The presence of LV scar at year 10 was cross-sectionally associated with higher LVMi (≈10 g/m 2), higher mass-to-volume ratio (0.1–0.2 g/mL), but lower …
