Lignocellulose dissociation with biological pretreatment towards the biochemical platform: A review.

Lignocellulose utilization has been gaining great attention worldwide due to its abundance, accessibility, renewability and recyclability. Destruction and dissociation of the cross-linked, hierarchical structure within cellulose hemicellulose and lignin is the key procedure during chemical utilization of lignocellulose. Of the pretreatments, biological treatment, which can effectively target the complex structures, is attractive due to its mild reaction conditions and environmentally friendly characteristics.

[Role and mechanism of motilin in colonic motility disorder].

Objective: To explore the role and mechanism of motilin in colonic motility disorder.

Methods: A total of 20 male Wistar rats (180 - 200 g) were randomly divided into 2 groups: water avoidance stress (WAS, n = 10) and sham water avoidance stress (SWAS, n = 10). Rats were exposed to 1 h WAS or SWAS daily for 10 consecutive days.
