Method of Preparing Sterilised Catgut

An improved method of preparing nisin.

1. Weights and ,-glucuronidase activity have been determined in lymphatic organs ofrats (lymph nodes of the neck, thymus and spleen) from 4 hr. to 15 days after total-body irradiation (200, 400 and 600 r.). 2. The activity of the enzyme increased in the first period after the irradiation (from 4 hr. to 5 days) when the tissues underwent a rapid decrease in weight. Histological examination showe...

Silk, Catgut, and Wound Infections *

Whether absorbable or non-absorbable suture material should be used in the repair of wounds has long been a highly controversial subject. Popular favor has swung from one extreme to the other repeatedly in the last century. Lord Lister was responsible for the initial popularity of catgut, just as Kocher was one of the first to abandon its use in favor of a non-absorbable material, i.e., silk. H...

A novel method for preparing microplastic fibers

Microscopic plastic (microplastic, 0.1 µm-5 mm) is a widespread pollutant impacting upon aquatic ecosystems across the globe. Environmental sampling has revealed synthetic fibers are prevalent in seawater, sediments and biota. However, microplastic fibers are rarely used in laboratory studies as they are unavailable for purchase and existing preparation techniques have limited application. To f...

des 6tudes r6alis6es sur cette glycoprot6ine r6duite et alkyl6e ~ en pr6sence d'ur6e et diff6rents pH, il n'est pas possible d'obtenir des pr6parations de poids mol6culaire plus faible que celui de l'orosomucoide natif. Ainsi, un peptide ac6tyl6 est pr6sent dans l'orosomucoide et puisqu'aucun amino acide N terminal n'a jamais 6t6 d6cel6 dans cette glycoprot6ine native ou d6natur6e, il paralt tr...
