The issue of adverse human health effects due to exposure to electromagnetic fields is still unclear, and congenital anomalies are among the outcomes that have been inconsistently associated with such exposure. We conducted a population-based, case-control study to examine the risk of congenital anomalies associated with maternal exposure to magnetic fields (MF) from high-voltage power lines during pregnancy in a community in northern Italy. We identified 228 cases of congenital malformations diagnosed in live births, stillbirths, and induced abortions among women living in the municipality of Reggio Emilia during the period 1998-2006, and a reference group of healthy newborns was matched for year of birth, maternal age, and hospital of birth. We identified maternal residence during early pregnancy and used Geographic Information System to determine whether the residences were within geocoded corridors with MF ≥0.1μT near high-voltage power lines, then calculated the relative risk (RR) of congenital anomalies associated with maternal exposure. One case and 5 control mothers were classified as exposed, and the RR associated with MF ≥0.1μT was 0.2 (95% CI: 0.0-2.0) after adjusting for maternal education. While small or moderate effects may have gone undetected due to low statistical power, the results of this study overall do not provide support for major effects of a teratogenic risk due to exposure to MF during early pregnancy. © 2011 Wiley Periodicals, Inc.

A small, 24V powered, portable mass spectrometer system, named ULISSES, for the study and visualization of gaseous volcanic emission is described. First deployments of the system have focused on both ground and airborne in situ measurement to monitor the awakening of the Turrialba Volcano in Costa Rica. Key gas measurements were acquired prior and after its eruption on 5 January 2010, confirming the presence of gas chemistry precursors typical of volcanic eruptions. Ground and airborne measurements were acquired to gain volcanological insight and as the first step towards the use of unmanned aerial vehicles (UAVs) as future airborne platforms and to confirm its unique capability to serve as a calibration/validation tool for satellite remote sensing data. Low parts per million (ppm) levels of helium and a large concentration of sulfur dioxide were measured in situ after the initial eruption. In particular, the SO2 data correlated with satellite remote sensing data. © 2010 Elsevier B.V.

To determine the distribution patterns and population status of Himalayan Grey Langur (Semnopithecus ajax) in Machiara National Park (34o-31 N; 73o-37 E), Azad Jammu and Kashmir (Pakistan), surveys were conducted from April, 2006 to April, 2007 using 'All Count Method during transect walks. Langur troops were confined to about 4,890ha area, at 1,790-4,000m above mean sea level. Each langur troop maintained its area of distribution and movement with a little overlapping. Census revealed that the population of langur in the National Park was organized in seven uni-male bisexual troops, two multi-male bisexual troops and three all-male bands with a population density of 0.160 (individuals/ha) (n=783), comprising 10.22% adult males, 22.35% adult females, 7.28% sub-adult males, 15.96% sub-adult females, 7.79% juvenile males, 28.99% juvenile females and 7.41% infants.

Grey langurs (Semnopithecus spp.) occupy a variety of habitats, ranging from lowland forests and semi-desert to alpine forests. Little is known about their foraging and ranging in alpine forests, which appear to contain less food than lowland forests. We conducted a 1-year study of Himalayan grey langurs (Semnopithecus ajax) in Machiara National Park, Pakistan, where they occur at relatively high altitudes (range 2000-4733 m). We followed three groups of different sizes and compositions and examined the effects of ecological and social factors on ranging and feeding. The home-range sizes of a small bisexual group (SBG), a large bisexual group (LBG), and an all-male group (AMG) were 2. 35 ± 0. 92 (mean ± SD; average of four seasons), 3. 28 ± 0. 55, and 3. 52 ± 1. 00 km2, respectively, and were largest in winter for all groups. The daily path lengths of the SBG, LBG, and AMG were 1. 23 ± 0. 28 (mean ± SD; average of four seasons), 1. 75 ± 0. 34, and 1. 84 ± 0. 70 km, respectively; that of the LBG was longer in winter, while that of the AMG was shorter in summer. Both the home-range size and daily path length of the AMG were larger than those of the other groups, even after partialling out the effect of group size differences. The mean altitude used by the langurs and the proportion of animals seen feeding did not differ among seasons or group types. As the mean temperature increased, the altitude used by langurs significantly increased for the SBG and LBG, but not for the AMG. On the other hand, as the temperature increased, the home-range sizes significantly decreased for the SBG and AMG, but not for the LBG. Rainfall did not show any correlation with ranging or feeding in any of the groups. Our results suggested that grey langurs in Machiara National Park employ a high-cost, high-return foraging strategy in winter, and that the ranging of the AMG also reflects its reproductive strategy. © 2013 Japan Monkey Centre and Springer Japan.

Morphological and morphometrical study was conducted on blood stream forms of Trypanosoma danilewskyi strain F Cc-1, isolated from laboratory-infected single breed juvenile common carp. A group of ten fish was intraperitoneally inoculated with 1000 live trypanosomes per fish. At the peak of parasitemia thin blood smears were prepared on precleaned glass slides on days 20, 30, 40 and 50 post infections (p.i). Blood smear was air dried, fixed with methanol and stained with May-Grünwald Giemsa stain. Stained trypanosomes were examined under light microscope at X 1000 magnification in the immersion oil. Morphology of trypanosome was recorded with a camera mounted on the microscope. From well stained slides 200 good specimens of T. danilewskyi FCc-1 were selected. For morphometric parameters, linear measurements in microns and nuclear area in square microns were taken by using Videoplan (Image Analysis System Kontron Bildanalyse, Germany). Morphometric measurements of T. danilewskyi strain FCc-1 were compared with reference strain of T. danilewskyi (Caa-1) already described earlier. The data revealed that T. danilewskyi strains FCc-1 and Caa-1 are the same.
