p75 neurotrophin receptor positive dental pulp stem cells: new hope for patients with neurodegenerative disease and neural injury.

Neurodegenerative diseases and neural injury are 2 of the most feared disorders that afflict humankind by leading to permanent paralysis and loss of sensation. Cell based treatment for these diseases had gained special interest in recent years. Previous studies showed that dental pulp stem cells (DPSCs) could differentiate toward functionally active neurons both in vitro and in vivo, and could promote neuranagenesis through both cell-autonomous and paracrine neuroregenerative activities.

Dlx2 over-expression: a possible mechanism for first branchial arch malformation.

The first branchial arch malformation (FBAM) is a rare congenital defect associated with anomalous development of the first and second branchial arches. Cause of FBAM still remains unknown, and is thought in most cases to be multifactorial, involving both genetic and enviromental factors. Dlx2 as a member of the Dlx homeobox gene family, plays a crucial role in the development of the first branchial arch.

[Study on oral Candida albicans apoptosis in vitro].

Purpose: Candida albicans is one of the main opportunistic pathogen for human , the aim of this study is to investigate the phenomena of apoptosis in oral Candida albicans induced by acetic acid.

Methods: The Candida albicans of clinical strains were induced to apoptosis by using a weak acid acetic acid.The apoptosis was detected by flow cytometry and TEM.
