Femoral Skeletal Growth in Early Infancy Assessed by Radiofrequency Echographic Multi‐Spectrometry

Journal of Clinical Ultrasound, EarlyView.
Radiofrequency echographic multi‐spectrometry (REMS) acquisition of raw ultrasound radiofrequency signals from neonatal bone. Signals undergo preprocessing and frequency‐domain analysis to extract spectral features reflecting bone properties. A software‐guided procedure then identifies and selects standardized regions of interest (ROIs).

Son of Sevenless Directly Links the Robo Receptor to Rac Activation to Control Axon Repulsion at the Midline

, 2006
SummarySon of sevenless (Sos) is a dual specificity guanine nucleotide exchange factor (GEF) that regulates both Ras and Rho family GTPases and thus is uniquely poised to integrate signals that affect both gene expression and cytoskeletal reorganization.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Growth phase variation in cell and nucleoid morphology in a Bacillus subtilis recA mutant

, 2001
The major role of RecA is thought to be in helping repair and restart stalled replication forks. During exponential growth, Bacillus subtilis recA cells exhibited few microscopically observable nucleoid defects.

Evolutionary Genomics of Staphylococcus aureus Reveals Insights into the Origin and Molecular Basis of Ruminant Host Adaptation [PDF]

, 2010
Phenotypic biotyping has traditionally been used to differentiate bacteria occupying distinct ecological niches such as host species. For example, the capacity of Staphylococcus aureus from sheep to coagulate ruminant plasma, reported over 60 years ago ...
