Exploding lakes in Vanuatu ＂Surtseyan-style＂ eruptions witnessed on Ambae Island

After a long silence, Lake Vui on Ambae Island burst into spectacular life on November 28, 2005, disrupting the lives of the 10,000 inhabitants on this sleepy tropical island in the SW Pacific. ＂Surtseyan-style＂ explosions burst through the Island＇s summit lake waters, forming a new tuff-cone, and threatening to form deadly lahars or volcanic floods. Such eruptions are rarely well observed, and these fleeting opportunities provide a chance to match volcanic processes with rock-sequences common in the geologic record...

Greenhouse gases fluxes and soil thermal properties in a pasture in central Missouri

引用

Journal of Environmental Sciences 2010年第7期22卷 1029-1039页

作者： Nsalambi Vakanda Nkongolo shane Johnson kent Schmidt Frieda Eivazi Department of Agriculture and Environmental Sciences College of Agriculture and Natural Science Lincoln University Harvard Forest Faculty of Arts and Sciences Harvard University

Fluctuations of greenhouse gases emissions and soil properties occur at short spatial and temporal scales, however, results are often reported for larger scales studies. We monitored CO2, CH4, and N2O fluxes and soil temperature （T）, thermal conductivity （k）, resistivity （R） and thermal diffusivity （D） from 2004 to 2006 in a pasture. Soil air samples for determination of CO2, CH4 and N2O concentrations were collected from static and vented chambers and analyzed within two hours of collection with a gas chromatograph. T, k, R and D were measured in-situ using a kD2 probe. Soil samples were also taken for measurements of soil chemical and physical properties. The pasture acted as a sink in 2004, a source in 2005 and again a sink of CH4 in 2006. CO2 and CH4 were highest, but N2O as well as T, k and D were lowest in 2004. Only k was correlated with C02 in 2004 while T correlated with both N2O （r = 0.76, p = 0.0001） and CO2 （r = 0.88, p = 0.0001） in 2005. In 2006, all gases fluxes were significantly correlated with T, k and R when the data for the entire year were considered. However, an in-depth examination of the data revealed the existence of month-to-month shifts, lack of correlation and differing spatial structures. These results stress the need for further studies on the relationship between soil properties and gases fluxes. k and R offer a promise as potential controlling factors for greenhouse gases fluxes in this pasture.

Bone density, microarchitecture and stiffness in Caucasian and Caribbean Hispanic postmenopausal American women

Bone Research 2014年第3期2卷 194-202页

Hispanic Americans of Caribbean origin are a fast-growing subset of the US population, but there are no studies on bone density, microstructure and biomechanical integrity in this minority group. In this study, we aimed to compare Caucasian and Caribbean Hispanic postmenopausal American women with respect to these characteristics. Thirty-three Caribbean Hispanics were age-matched to thirty-three Caucasian postmenopausal women. At the lumbar spine, the Hispanic women had significantly lower areal bone mineral density （aBMD）. At the radius by high-resolution peripheral quantitative computed tomography （HR-pQCT）, there were minimal differences between Hispanic and Caucasian women. At the tibia, Hispanic women had lower trabecular volumetric bone density and trabecular number, and higher trabecular separation. Individual trabecula segmentation （ITS） analyses indicated that at the tibia, Hispanic women not only had significantly lower bone volume fraction, but also had significantly lower rod bone volume fraction, plate trabecular number, rod trabecular number and lower plate-plate, plate-rod and rod-rod junction densities compared to Caucasian women. The differences in bone quantity and quality contributed to lower whole bone stiffness at the radius, and both whole bone and trabecular bone stiffness at the tibia in Hispanic women. In conclusion, Hispanic women had poorer bone mechanical and microarchitectural properties than Caucasian women, especially at the load-bearing distal tibia.

Neurotrophic factors: from neurodevelopmental regulators to novel therapies for Parkinson's disease

引用

Neural Regeneration Research 2014年第19期9卷 1708-1711页

作者： shane V.Hegarty Gerard W.O’keeffe Aideen M.Sullivan Department of Anatomy and Neuroscience Biosciences InstituteUniversity College Cork

Neuroprotection and neuroregeneration are two of the most promising disease-modifying ther- apies for the incurable and widespread Parkinson＇s disease. In Parkinson＇s disease, progressive degeneration of nigrostriatal dopaminergic neurons causes debilitating motor symptoms. Neurotrophic factors play important regulatory roles in the development, survival and maintenance of specific neuronal populations. These factors have the potential to slow down, halt or reverse the loss of nigrostriatal dopaminergic neurons in Parkinsoffs disease. Several neurotrophic fac- tors have been investigated in this regard. This review article discusses the neurodevelopmental roles and therapeutic potential of three dopaminergic neurotrophic factors： glial cell line-derived neurotrophic factor, neurturin and growth/differentiation factor 5.

Targeting transcriptional regulators to regenerate midbrain dopaminergic axons in Parkinson's disease

引用

Neural Regeneration Research 2017年第11期12卷 1814-1815页

作者： shane V.Hegarty Aideen M.Sullivan Gerard W.O'keeffe Department of Anatomy and Neuroscience Western Gateway BuildingUniversity College CorkCorkIreland

Introduction： Parkinson＇s disease （PD） is a chronic, age-re- lated neurodegenerative disorder that affects 1-2% of the population over the age of 65. PD is characterised by the progressive degeneration of nigrostriatal dopaminergic （DA） neurons. This leads to disabling motor symptoms, due to the striatal DA denervation. Despite decades of research, there is still no therapy that can slow, stop or regenerate the dying midbrain DA neurons in PD.
