Twitter as a tool for social movement: An analysis of feminist activism on social media communities.

In recent years, social media has been widely used as a tool for feminist social movements, addressing social problems such as sexual assault traumatization. This research aims at understanding how social media users utilized Twitter to describe traumatic sexual assault experiences and reasons victims chose not to disclose their experiences (Study 1), and how users became a part of the digital activism (i.e.

Cloning and heterologous expression of a thermostable pectate lyase from Penicillium occitanis in Escherichia coli.

The entire pectate lyase cDNA (Pel1) of Penicillium occitanis was cloned from a cDNA bank and sequenced. The ORF exhibited a great homology to Penicillium marneffei and conservation of all features of fungal pectate lyases such as the barrel structure with "eight right-handed parallel β-helix" architecture. The structure modeling also showed the interesting resemblance with thermostable pectate lyases since several specific residues were also shared by Pel1 and these thermostable enzymes.
