By UBALDO RIFi , FELIX MILGROM AND SIDNEY SHULMAN M ANY METHODS have been used to purify human plasminogen, including selective denaturation,1 salting out with ammonium sulfate,2 zone electrophoresis,3 and various types of column chromatography,48 among others.9’#{176} The resultant preparations have still shown physical heterogeneity. Similar heterogeneity has been seen in the corresponding pl...

Revistin, a substance that strongly inhibits the reverse transcriptase activity of murine leukemia virus in our screening system, was obtained from a cultured broth of a soil streptomyces which was closely related to Streptomyces filipinensis. The assay method for the activity was based on the inhibition by a test material of the incorporation of 3H-dTMP into DNA synthesized by the reverse tran...

STUDY oi’ THE SERUM protein patterns in patients with chronic rheumatic diseases has already been reported in an earlier publication (1). In that work the proteins were separated by a salting-out technic and the fractions estimated by the biuret reaction. The results confirmed that hyperglobulinemia is a frequent finding in chronic rheumatic conditions, being often accompanied also, though in l...

A new study in the Journal of Alzheimer's Disease finds a strong link between some food preservatives and an increased risk of death from Alzheimer's, Parkinson's and diabetes. These food additives have previously been linked with several different types of cancer, including prostate, colon and rectum. Sodium and potassium nitrates are used in the processes of salting, pickling and curing foods...

The aldehyde 3-methylbutanal is a key aroma compound for many types of cheeses. Intracellular enzymes cheese starter cultures are predominantly responsible the conversion leucine into 3-methylbutanal. Environmental conditions during manufacturing also play role in production Our work shows that salting has detrimental effect on capacity Lactococcus lactis subsp. DS84445 to produce In respect, p...

The effect of concentrated NaCl (200 g L−1) on CWO oxalic acid and acetic over MnCeOx was investigated at 110 °C 0.5 MPa O2 to explore the potential using for shale gas wastewater treatment. presence hindered conversion, which from ATR-IR spectroscopy attributed salting out increasing surface coverage with formation strongly adsorbed intermediates, slowing mineralisation. In addition, weak adso...
