All abiotic and biotic stresses induce or involve oxidative stress to some degree, and the plant ability to control oxidant levels is highly correlated with stress tolerance. Polyamines (PAs) have antioxidant properties and their induction in response to stress is well known. Mesembryanthemum crystallinum L., Thellungiella halophila Mey., Plantago major L. and Geum urbanum L. plants were grown ...
BACKGROUND Transseptal puncture with a conventional mechanical technique can fail because of a resistant interatrial septum. We evaluated the efficacy and safety of a new method to cross-resistant septae by transmitting radiofrequency (RF) energy through the transseptal needle. METHODS AND RESULTS Among 269 consecutive transseptal punctures, 13 (5%) were unsuccessful in 12 different patients ...
Exposure of the moderately halophilic bacterium, Deleya halophila, to high NaC1 concentrations (2 or 2.5 M) resulted in a transient cessation of cell division. The time taken for the cells to adapt and grow depended on the final salt concentrations. During the initial phases of adaption to high salt both the rate of protein synthesis and amino acid uptake were transiently inhibited. The extent ...
THE reciprocal effect of two neighbouring structures of different origins on each other during development is of considerable interest to the embryologist. Such a relationship exists between the columella auris and the auditory capsule in the vicinity of the fenestra ovalis. This particular relationship, in addition, embraces an aspect of fundamental importance to the morphologist viz. the poss...
Intracardiac echocardiography (ICE) serves as an adjunct to fluoroscopy for electrophysiological procedures by identifying critical anatomic landmarks and confirming catheter-endocardial contact. In the present study, we investigated the usefulness of ICE for radiofrequency catheter ablation. ICE was utilized to guide transseptal puncture in 19 patients undergoing radiofrequency catheter ablati...
AIMS Transseptal (TS) puncture during atrial fibrillation (AF) ablation is a relatively safe procedure in experienced hands. However, major and minor complications cannot be completely ruled out. Real-time three-dimensional transeosophageal echocardiography (RT 3D TEE) is a novel imaging technology that permits direct visualization of the fossa ovalis in a 3D perspective, thereby sensibly lower...
Seagrasses around the world are threatened by human activities that degrade water quality and reduce light availability. In this study, light requirements were determined for four common and abundant seagrasses along the Gulf coast of peninsular Florida using a threshold detecting algorithm. Light requirements ranged from 8% to 10% of surface irradiance for Halophila engelmannii to 25-27% of su...
