8 of the World ’s Most Dangerous Volcanoes, According to Experts

Dozens of people have died, hundreds are missing and many more homes were destroyed after separate volcanic eruptions in Hawaii and Guatemala that made headlines worldwide in recent months. And although those volcano eruptions are not part of a trend, experts have said, the volcanoes in question are far from the only dangerous ones in the world. When assessing which volcanoes are the most dangerous in the world, however, several factors come into play, including population density surrounding active volcanoes, the types of magma that emerge during eruptions and each volcano’s eruption history. For example, an explosive volcanic eruption in a remote area is not as dangerous as one in a populous region that requires mass evacuations. And volcanoes that go a long time without erupting pose a higher risk for eruption because of mounting pressure inside them. Magma content is one way to assess a particular volcano’s danger level, according to Stanley Mertzman, a geosciences professor at Franklin &Marshall College in Lancaster, Pa. Mertzman says experts will look at the level of silica, a rock-forming compound that affects the thickness of lava and a volcano’s overall shape, according to the USGS. Silica can indicate how dangerous an eruption can be because it tends to crystallize into chains in cooling lava, increasing its viscosity, in turn creating thicker magma that can make a volcano erupt more explosively. “The degree of danger increases dramatica...

LoweAbstractDNA sequencing has been characterised by scholars and life scientists as an example of ‘big’, ‘fast’ and ‘automated’ science in biology. This paper argues, however, that these characterisations are a product of a particular interpretation of what sequencing is, what I call ‘thin sequencing’. The ‘thin sequencing’ perspective focuses on the determinatio...

RaghavamenonAbstractThermal oxidation products of edible oils including aldehydes, peroxides and polymerized triglycerides formed during the cooking process is increasingly debated as contributory to chronic degenerative diseases. Depending on the oil used for cooking, the source of fatty acids and its oxidation products may vary and would have a differential influence on the physiological process. Coco...

In this study, control and 5-LO-expressing HEK293 cells were stimulated in the presence of 20:4 n-3. Metabolites were characterized by LC-MS/MS and their anti-inflammatory properties assessed using AA-induced autocrine neutrophil stimulation and leukotriene B4-mediated chemotaxis. 8-hydroxy-9,11,14,17-eicosatetraenoic acid (Δ17-8-HETE) and 8,15-dihydroxy-9,11,13,17-eicosatetraenoic acid (Δ17-8,15-diHETE) were identified as novel metabolites. Δ17-8,15-diHETE production was inhibited by the leukotriene A4 hydrolase inhibitor SC 57461A. Autocrine neutrophil leukotriene stimulation and neutrophil chemotaxis, ...

In this study, whether autocrine IL‑10 regulates Op18/stathmin signaling in NCI‑H1299 cells was examined by neutralizing IL‑10 using a targeted antibody. In vitro neutralization of IL‑10 by anti‑IL‑10 antibody impaired the capacities of the NCI‑H1299 cells to proliferate, form colonies and migrate. Furthermore, the expression levels of caspase‑3 and ‑8, and sensitivity to Taxol were increased. Neutralizing IL‑10 downregulated Op18/stathmin expression and its phosphorylation at Ser25 and Ser63 sites, and suppressed the activities of upstream kinases, extracellular signal‑regulated kinase (ERK...

For this purpose, a prospective cohort of 103 pathologically confirmed patients with PCNSL was enrolled in this study. Ophthalmologic examinations were performed both at diagnosis and during follow‑up. The patients with PCNSL with suspected intraocular involvement underwent vitrectomy for confirmation. Patients who prese...

Targeting LRH‑1 in hepatoblastoma cell lines causes decreased proliferation. Oncol Rep. 2018 Oct 15;: Authors: Jin J, Jin J, Woodfield SE, Patel RH, Jin NG, Shi Y, Liu B, Sun W, Chen X, Yu Y, Vasudevan SA Abstract Hepatoblastoma is the most common malignant liver tumor in children. Since it is often unresectable and exhibits drug resistance, the treatment of advanced hepatoblastoma is challenging. The orphan nuclear receptor liver receptor homolog‑1 (LRH‑1) serves prominent roles in malignancy; however, to the best of our knowledge, the role of LRH‑1 in hepatoblastoma remains unknown. In the pr...
