摘要:
The invention relates to a thrombolytic enzyme referred to as Thrombinase having a molecular weight of 31,000 to 32,000. Such a thrombolytic enzyme can be used for dissolving blood clots. The process comprises culturing a filtrate of Bacillus sphaericus sero type H5a 5b, removing the cell, subjecting the cell supernatant to filtration, salting out the retentate, subjecting the precipitate to dialysis, reprecipitating the precipitate and then reconstituting in buffer and finally decolourizing, purifying and dialyzing.

摘要:
A process for producing herbicides from a fungus Alternaria alteranata f.sp. lantanae deposited as a pure culture as MTCC 5432 and ITCC-4896, comprising culturing the fungus in a liquid broth; subjecting the broth to the step of filtration to separate the broth containing phytotoxins from mycelium; extracting the phytotoxins from said broth to obtain the phytotoxins; and subjecting the phytotoxins to chemical characterization.
摘要:
In nuclear magnetic resonance spectroscopy spatial localization of the output signal is achieved by using gradient magnetic fields and radio-frequency inversion pulses to define slices through a sample from which a signal is obtained. The use of intersecting slices allows the field of view to be reduced to the region of intersection to study a localized volume of interest in the sample. Conventionally, three orthogonal gradient magnetic fields can be defined by energizing successively three gradient magnetic field coils. With the present invention combinations of the gradient magnetic field coils are energized simultaneously to allow the field of view to be more closely conformed to a described volume of interest. This simultaneous energization allows the field of view to be rotated relative to the axes of the coils and/or allows non-orthogonal intersecting slices to be defined to alter the shape of the field of view at the intersection of the slices. Further, more than three slices may be defined to allow polyhedral fields of view to be defined. The invention is applicable to many modern forms of nuclear magnetic resonance spectroscopy.

摘要:
To combat the accumulation of plaque on dentures, a non self-supporting coating of a non-toxic, negatively charged polysaccharide is applied. The polysaccharide coating is gradually sacrificed or ablated during wear. Ablation appears to remove microorganisms along with coating material. The polysaccharide is further defined by an ability to reduce the adhesion of Streptococcus salivarius cells in a simple in vitro bacterial adhesion test by at least 25% over a control.
