Caspase inhibitors affect the kinetics and dimensions of tracheary elements in xylogenic Zinnia (Zinnia elegans) cell cultures [PDF]

, 2010
Background The xylem vascular system is composed of fused dead, hollow cells called tracheary elements (TEs) that originate through trans-differentiation of root and shoot cambium cells. TEs undergo autolysis as they differentiate and mature.

Discovery of Novel MLSB Resistance Methylase Genes and Their Associated Genetic Elements in Staphylococci [PDF]

, 2016
Erythromycin resistance methylases (Erm) confer resistance to three classes of clinically important antibiotics, the macrolides, the lincosamides, and the streptogramins B (MLSB). Erm methylases are located on acquired genetic elements and are widespread

Identification of genetic elements associated with EPSPs gene amplification.

PLoS ONE, 2013
Weed populations can have high genetic plasticity and rapid responses to environmental selection pressures. For example, 100-fold amplification of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene evolved in the weed species Amaranthus palmeri

Association of trace elements abnormalities with thyroid dysfunction

African Health Sciences, 2021
Background: The metabolic pathways can be affected by dysregulation in thyroid hormone levels which in turn can arise from environmental chemical exposure. This study investigated the association of selected trace elements with thyroid dis- orders in a Saudi population. Methods: Urine samples collected from 100 participants (50 thyroid disorder ...
