We present here the optical properties of humiclike substances (HULIS) isolated from the fine fraction of biomass-burning aerosol collected in the Amazon basin during the LBA-SMOCC (Large scale Biosphere atmosphere experiment in Amazonia – SMOke aerosols, Clouds, rainfall and Climate) experiment in September 2002. From the isolated HULIS, aerosol particles were generated and their scattering an...

Out of the vast array of species in the plant kingdom — variously estimated at from 200,000 to 800,000 — a few have been employed in primitive societies for millennia to induce visual, auditory, tactile, and other hallucinations. Because of their earthly effects that often defy description, they have usually been considered sacred and have played central roles as sacraments in aboriginal religi...

Despite the gaps existing in our contemporary understanding of the origin, the function, the mode of regulation and even the eventual fate of plasma cholesterol, various drugs have been introduced and applied to lower this particular lipid in the blood stream of man. It is perhaps suggestive of the clinical eagerness to accomplish this lowering that the precise modus operandi by which any of th...

OBJECTIVES To describe our experience in the management of patients with osteogenesis imperfect (OI). MATERIAL AND METHODS We conducted a retrospective study of a series of cases affected with OI treated in the Clínica Univesidad de Navarra from 1980 to 2007, with a mean follow up of 17.3 years (7-27 years). We collected descriptive data of the sample, the fractures and the deformities, and t...

Remote sensing has traditionally be done with satellites and manned aircraft. While these methods can yield useful scientific data, satellites and manned aircraft have limitations in data frequency, process time, and real time retasking. Small low-cost unmanned aerial vehicles (UAVs) can bridge the gap for personal remote sensing for scientific data. Precision aerial imagery and sensor data req...

in this study, anion-exchange chromatography was used to purify factor vii and factor ix from prothrombin complex (ppsb), which contains coagulation factors ii, vii, ix and x. for this purpose, deae-sepharose cl-6b gel , pharmacia column xk-26 , high flow rate and two stepwise gradients with phosphate citrate buffer were used. the yield of the two lyophylized products, factor vii and factor ix ...

background: factor v g1691a (fv leiden), fii ga20210, and methylenetetrahydrofolate reductase (mthfr) c677t mutations are the most common genetic risk factors for thromboembolism in the western countries. however, there is rare data in iran about cerebral venous and sinus thrombosis (cvst) patients. the aim of this study was to evaluate the frequency of common genetic thrombophilic factors in c...
