Chemical tracer methods for determining contributions to primary organic aerosol (POA) are fairly well established, whereas similar techniques for secondary organic aerosol (SOA), inherently complicated by time-dependent atmospheric processes, are only beginning to be studied. Laboratory chamber exp...

The short-term response of some soil physical, chemical and biological properties, and the growth of beet, to the application of vermicompost-compost mix and/or bone meal at different doses in an organic system was evaluated in the present work. Fractions of soil organic matter after amendment appli...

Analytic expressions for maximum chemical concentration attained in plants, and time this takes for uptake from surrounding soil were derived from a simple two-compartment soil/water-plant model. To illustrate, for the antibiotic norflxacin undergoing first order loss in the soil/water phase with a...

We investigated whether pediatric AML samples (N=61) were sensitive to the tyrosine kinase inhibitor SU11657 (similar to the clinically available drug sunitinib) in vitro, and whether sensitivity was related to expression of, and mutations in, FLT3 and KIT. Overall, SU11657 showed only moderate cyto...

We studied the interaction of anti-Yo antibodies with Purkinje cells in slice (organotypic) cultures of rat cerebellum. We incubated cultures with immunoglobulin G (IgG)-containing anti-Yo antibodies using titers of anti-Yo antibody equivalent to those found in CSF of affected patients. Cultures wer...

The aim of the present study is to investigate the correlation between microbial activity, i.e., biological stability measured by aerobic (OD20 test) and anaerobic tests (ABP test), and odour emissions of organic fraction of municipal solid waste during anaerobic digestion in a full-scale treatment...

We observed that Labrasol has the ability to solubilize various cationic Eudragits such as Eudragit RSPO, Eudragit RLPO and Eudragit EPO at a concentration as high as 200 mg/ml. We also evaluated the ability of Labrasol to act as a nanoparticle stabilizer due to its amphiphilic nature and high HLB o...

The major POP found in all samples was 1,1-dichloro-2,2-bis(4-chlorophenyl)ethene (4,4'-DDE) followed by 4,4'-DDT. 4,4'-DDE, 4,4'-DDT, PCBs and beta- and gamma-HCH were significantly decreasing over time. The PBDEs were found at low concentrations, with an increasing temporal trend for BDE-153. CONC...

We evaluated the addition of organic solvent as an alternative MS-compatible method to decrease protein adsorption. The effect of the solvent addition was emphasized using classical methods for estimating reversible and irreversible adsorption. In many cases, organic solvents were effective at decre...
