Microbial signature profiles of periodontally healthy and diseased patients

submitted by: apcolombo
Aim: To determine microbial profiles that discriminate periodontal health from different forms of periodontal diseases. Methods: Subgingival biofilm was obtained from patients with periodontal health (27), gingivitis (11), chronic periodontitis (35) and aggressive periodontitis (24), and analysed for the presence of >250 species/phylotypes using HOMIM. Microbial differences among groups were examined by Mann–Whitney U-test. Regression analyses were performed to determine microbial...

biosights: September 29, 2014 - Cdc42 prompts a change of heart

submitted by: JCB
The Drosophila heart is a simple tubular structure with a central lumen. Vogler et al. reveal that the small GTPase Cdc42 and actin-nucleating formin proteins promote lumen formation by regulating the dynamics of non-muscle myosin in cardioblasts during heart morphogenesis. This biosights episode presents the paper by Vogler et al. from the September 29, 2014, issue of The Journal of Cell Biology and includes an interview with two of the paper's authors, Georg Vogler and Rolf Bodmer...

Jellyfish swarms in the Gulf of Mexico help researchers identify environmental changes in the water. Dr. Monty Graham at the University of Southern Mississippi studies these massive jellyfish swarms that can stretch for up to 100 miles.

biosights: September 1, 2014 - Deploying exosomes in a battle of the sexes

submitted by: JCB
The paired accessory glands of male Drosophila secrete multiple signaling factors into the seminal fluid that promote reproductive success by altering the recipient female's physiology and behavior. Corrigan et al. reveal that the secondary cells of accessory glands secrete membrane-bound exosomes in a BMP-dependent manner that, after being transferred into the female reproductive tract, inhibit the female's inclination to re-mate with other male flies. This biosights episode presents the...
