Stem diameter variations as a versatile research tool in ecophysiology

Changes in stem diameter of herbaceous and woody plants as a measure of internal water balance

Secretory microRNAs as a versatile communication tool.

The physiological role of microRNAs (miRNAs) is widely appreciated as a fine-tuner to post-transcriptionally regulate the expression of multiple genes in the cells of origin. Here, we highlight two significant characteristics of miRNAs: (1) they are secreted from the producing cells and (2) they can deliver the gene silencing signals between living cells in vitro and in vivo. The circulation of...

The chest diameter as a diagnostic tool.

The expressions “barrel chest” and “increased antero-posterior diameter of the chest” are frequently encountered in physical diagnosis. These terms are often considered indicative of emphysema.” Several authors3’4 feel, however, that barrel chest is not found exclusively in emphysema and that it may be part of the natural aging process. One group4 points out that in the older ages patients with...

Iranian Stem Cell Research Trends: Bibliometric Analysis as a Tool

This Bibliometric study was carried out to investigate the trends in stem cell research in Iran from 1995 to 2010. Original research and review articles were considered and publications were identified with the keyword "stem cell" and an affiliation to an Iranian institution. Data were obtained from the Institute for Scientific Information (ISI) Web of Science databases and Scopus. We found 491...

Human Engineered Heart Tissue as a Versatile Tool in Basic Research and Preclinical Toxicology

Human embryonic stem cell (hESC) progenies hold great promise as surrogates for human primary cells, particularly if the latter are not available as in the case of cardiomyocytes. However, high content experimental platforms are lacking that allow the function of hESC-derived cardiomyocytes to be studied under relatively physiological and standardized conditions. Here we describe a simple and r...
