  • Publication number: 20210100929
    Abstract: Disclosed is a fibrinogen composition. The fibrinogen composition comprises denatured fibrinogen hydrogel having a fibrinogen concentration ranging from 0.1 to 15 wt.-% and a fibrinogen hydrogel forming salt at a concentration less than a threshold concentration to form the fibrinogen hydrogel. In some examples, the fibrinogen composition is dehydrated denatured fibrinogen hydrogel, where the fibrinogen composition comprises salt at a concentration no greater than 20 wt.-%.

  • Patent number: 10940233
    Abstract: Provided is a method of forming a fibrinogen hydrogel composition, the method including providing a fibrinogen hydrogel or precursor thereof, comprising fibrinogen hydrogel forming salt. The fibrinogen hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrinogen hydrogel. The method further includes denaturing the fibrinogen hydrogel such as by heating. The method optionally further includes combining the fibrinogen hydrogel with a carrier material. When present, the concentration of the carrier material typically ranges from 0.1 to about 50 wt.-%. The method further includes reducing the salt concentration below the threshold concentration to form a fibrinogen hydrogel.
    Type: Grant

  • Patent number: 5274635
    Abstract: A method and apparatus for aligning a digital communication data stream across a cell network, wherein plurality of timeslot samples are generated by sampling the digital communication data stream transferred over a first circuit-switching communication link. The timeslot samples are assembled into a series of communication cells in a bit or byte skewed arrangement. An align flag in the header of a communication cell indicates that the communication cell contains an aligned timeslot sample.
