Abstract: A process is provided for making bulk calcium magnesium acetate in a substantially pure crystalline form. The crystalline CMA contains less than about 0.5% of water soluble impurities.

Abstract: A process and medium are disclosed for the lyophilization of red blood cells which comprises the use of solutions including monosaccharide hexoses and pentoses, and/or biocompatible polymers to permit the reconstitution of viable red blood cells.

Abstract: A method is provided for fabricating a shaped article from aqueous collagen-containing materials. A dispersion containing collagen and a surfactant is cast upon a mold of thermoplastic material and dried by a ramped drying profile under controlled conditions of relative humidity and temperature. The controlled drying allows for initial renaturation of the collagen dispersion then drying at high humidity to form a product with minimal residual stress.

Abstract: The invention relates to nucleotide sequences, including a substantially purified gene which codes for an oxygen-binding protein, and a gene promoter/regulator which is useful in subjecting the translation/transcription of DNA sequences to selective regulation by external control, and plasmid vectors containing those nucleotide sequences, which are valuable bioprocessing catalysts for enhancing the growth characteristics of cells, and increasing production of various proteins and metabolites of those cells. Methods for the use of these nucleotide sequences and related plasmids for a range of applications including oxygen supply to cells, growth enhancement, expression of various gene products, enhancement of oxygen-requiring processes, binding and separation of oxygen from liquids and gases, and a range of oxidative reactions are also disclosed.

Abstract: Novel N-haloacetylphenylamino carbonyl oximes represented by the formula ##STR1## wherein Ar is aryl, R.sup.1 is halomethyl, R.sup.2 is hydrogen, alkyl or aryl, R.sup.3 is hydrogen, alkyl or aryl, n is 0 or 1 and R is hydrogen, aryl, alkyl, alkenyl or alkynyl, with the proviso that R.sup.2 and R.sup.3 may be joined together to form a carbocyclic ring of 5 to 6 carbon atoms or a heterocyclic ring of one N, O or S hetero atom and 4 to 5 carbon atoms. The oxime compounds are useful as herbicides and plant growth regulators.
