Changes were studied in the standard solubility curve of fresh serum proteins by alterations in pH, temperature, concentration of protein, and nature of the salt used for precipitation. The principal factor affecting the precipitation of protein fractions was a change in temperature. In order to investigate the proteins in their original states low temperatures are necessary. Protein fraction A...

A detailed climatological study shows that the average annual precipitation over Lake Michigan is 6 percent less than that of the land portion of the basin. This is contrary to results of most previous studies which indicated that lake and land precipitation were equal. However, the results of this study are more accurate than the earlier findings because they are based on more detailed informa...

Protein extraction, precipitation, and recovery methods were evaluated by this study using a green alga—Chlorella sorokiniana. A mechanochemical cell disruption process was applied to facilitate protein extraction from microalgal biomass. Optimization of the resulted in milling conditions that achieved 52.7 ± 6.45%. The consequent acid precipitation method optimized recover 98.7% proteins slurr...

Protein aggregation and precipitation is associated with many debilitating diseases including Alzheimer's, Parkinson's, and light-chain amyloidosis. β-Casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. Hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

The austral westerlies strongly influence precipitation and ocean circulation in the southern temperate zone, with important consequences for cultures and ecosystems. Global climate models anticipate poleward retreat of the austral westerlies with future warming, but the available paleoclimate records that might test these models have been limited to South America and New Zealand, are not fully...

A fundamental objective in studies of climate-erosion-tectonics coupling is to document convincing correlation between observable indicators of these processes on the scale of a mountain range. The eastern Himalayas are a unique range to quantify the contribution of tectonics and climate to long-term erosion rates, because uniform and steady tectonics have persisted for several million years, w...

A surface-precipitation-rate retrieval algorithm for 13-channel Advanced Microwave Sounding Unit (AMSU) millimeter-wave spectral observations from 23 to 191 GHz is described. It was trained using cloudresolving fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) simulations over 106 global storms. The resulting retrievals from the U.S. N...

Various mammalian species contain an anionic serum protein that reacts specifically with native DNA. It is considerably less reactive with single-strand DNA and does not react with monodeoxyribonucleotides, homopolyribonucleotides, or duplexes of homopolyribonucleotides. Synthetic dA.dT was an effective inhibitor of the reaction with native DNA, while Micrococcus luteus DNA and dG.dC were not i...

NCOMPLETE RECOVERIES OF CREATININE added to plasma or serum have been reported by investigators who have used a tungstic acid protein precipitation and the picric acid method of analysis (1-7). Controversy exists as to whether the creatinine is lost by adsorption on the protein precipitate or whether the alkaline picrate formed in these circumstances is modified so that less color is formed. Ow...
