Selenium Biofortification Impacts the Tomato Fruit Metabolome and Transcriptional Profile at Ripening.

In the present work, the effects of enriching tomatoes with selenium were studied in terms of physiological, metabolic, and molecular processes in the last stages of fruit development, particularly during ripening. A selenium concentration of 10 mg L with sodium selenate and selenium nanoparticles was used in the spray treatments on the whole plants. No significant effects of selenium enrichment were detected in terms of ethylene production or color changes in the ripening fruit.

Se-Enrichment Pattern, Composition, and Aroma Profile of Ripe Tomatoes after Sodium Selenate Foliar Spraying Performed at Different Plant Developmental Stages.

Foliar spray with selenium salts can be used to fortify tomatoes, but the results vary in relation to the Se concentration and the plant developmental stage. The effects of foliar spraying with sodium selenate at concentrations of 0, 1, and 1.5 mg Se L at flowering and fruit immature green stage on Se accumulation and quality traits of tomatoes at ripening were investigated.

[In-hospital outcomes of endarterectomy and coronary artery bypass grafting in multiple diffuse lesions of coronary arteries].

Background: According to a series of studies, performing coronary endarterectomy in direct myocardial revascularization increases the risk of myocardial infarction and in-hospital mortality. There are no commonly accepted indications for carrying out endarterectomy, and in clinical practice this technique is used in severe diffuse lesions of coronary arteries.

Aim: The study was aimed at assessing in-hospital clinical outcomes of coronary artery bypass grafting (CABG) with the use of endarterectomy in patients with severe multiple diffuse lesions of coronary arteries.

A dynamic human motion: coordination analysis.

This article is concerned with the generic structure of the motion coordination system resulting from the application of the method of virtual holonomic constraints (VHCs) to the problem of the generation and robust execution of a dynamic humanlike motion by a humanoid robot. The motion coordination developed using VHCs is based on a motion generator equation, which is a scalar nonlinear differential equation of second order. It can be considered equivalent in function to a central pattern generator in living organisms.

[Capacities of multidetector spiral computed tomography in the planning and postoperative examination of patients undergoing coronary artery bypass surgery].

Multiple investigations show that multidetector spiral computed tomography (MSCT) bypass grafting becomes an alternative to invasive coronary angiography in detecting coronary graft stenoses and occlusions. The investigation retrospectively estimated the patency of aortocoronary and mammary coronary artery anastomoses by MSCT bypass grafting. Examinations were made in 85 (326 anastomoses) patients who had undergone aortocoronary and mammary coronary artery bypass surgery and had MSCT bypass grafting within 3 years after the surgery.
