Predicted Three-Dimensional Structure of the GCR1 Putative GPCR in and Its Binding to Abscisic Acid and Gibberellin A1.

GCR1 has been proposed as a plant analogue to animal G-protein-coupled receptors that can promote or regulate several physiological processes by binding different phytohormones. For instance, abscisic acid (ABA) and gibberellin A1 (GA1) have been shown to promote or regulate germination and flowering, root elongation, dormancy, and biotic and abiotic stresses, among others. They may act through binding to GCR1, which would put GCR1 at the heart of key signaling processes of agronomic importance.

The ÓMICAS alliance, an international research program on multi-omics for crop breeding optimization.

The OMICAS alliance is part of the Colombian government's Scientific Ecosystem, established between 2017-2018 to promote world-class research, technological advancement and improved competency of higher education across the nation. Since the program's kick-off, OMICAS has focused on consolidating and validating a multi-scale, multi-institutional, multi-disciplinary strategy and infrastructure to advance discoveries in plant science and the development of new technological solutions for improving agricultural productivity and sustainability. The strategy and methods described in this article, involve the characterization of different crop models, using high-throughput, real-time phenotyping technologies as well as experimental tissue characterization at different levels of the omics hierarchy and under contrasting conditions, to elucidate epigenome-, genome-, proteome- and metabolome-phenome relationships.

Preparation of vibrational quasi-bound states of the transition state complex BrHBr from the bihalide ion BrHBr.

Efficient strategies that allow the preparation of molecular systems in particular vibrational states are important in the application of quantum control schemes to chemical reactions. In this paper, we propose the preparation of quasi-bound vibrational states of the collinear transition state complex BrHBr, from vibrational states of the bihalide ion BrHBr, that favor the bond selective breakage of BrHBr. The results shown complement the investigation that we reported in a previous paper, [A.

Pneumothorax After a Fall in a Healthy Adolescent Athlete.

A pneumothorax is a pathological collection of air in the pleural space within the thoracic cavity. Pneumothoraxes are classified by the underlying etiology as spontaneous or traumatic, with spontaneous pneumothoraxes being further categorized into primary and secondary causes. Management historically involved admission with possible administration of oxygen or chest tube placements based on severity.

Validation by Molecular Dynamics of the Major Components of Sugarcane Vinasse, On a Surface of Calcium Carbonate (Calcite).

There is ongoing interest in the alcohol industry to significantly reduce and/or add value to the liquid residue, vinasse, produced after the distillation and rectification of ethanol from sugar cane. Vinasse contains potassium, glycerol, and a protein component that can cause environmental issues if improperly disposed of. Currently, some industries have optimized their processes to reduce waste, and a significant proportion of vinasse is being considered for use as an additive in other industrial processes.

Heuristic optimization of analytic laser pulses for vibrational stabilization of ultracold KRb.

We proposed a methodology that allows to maximize the population transfer from a high vibrational state of the Σ triplet state to the vibrational ground state of the Σ singlet state though the optimization of one pump and one dump laser pulses. The pump pulse is optimized using a fitness function, heuristically improved, that includes the effect of the spin-orbit coupling of the KRb [b-A]-scheme. The dump pulse is optimized to maximize the population transfer to the ground state.

How much for a broken heart? Costs of cardiovascular disease in Colombia using a person-based approach.

The shift of the Noncommunicable Diseases (NCDs) epidemic, including cardiovascular disease, from developed to Low and Middle Income Countries (LMIC), creates new challenges in contexts where there is poor information on healthcare costs. Clearly this information is essential for planning, and its relevance is even more valuable as a driver for prevention and control of NCDs. This paper begins to address that handicap by estimating the healthcare cost of Cardiovascular Disease (Coronary Heart Disease and Stroke) in Colombia, using a person-based approach.

Molecular Dynamics of a Water-Absorbent Nanoscale Material Based on Chitosan.

Although hydrogels have been widely investigated for their use in materials science, nanotechnology, and novel pharmaceuticals, mechanistic details explaining their water-absorbent features are not well understood. We performed an all-atom molecular dynamics study of the structural transformation of chitosan nanohydrogels due to water absorption. We analyzed the conformation of dry, nanoscaled chitosan, the structural modifications that emerge during the process of water inclusion, and the dynamics of this biopolymer in the presence of nature's solvent.

Analytical optimal pulse shapes obtained with the aid of genetic algorithms.

We propose a methodology to design optimal pulses for achieving quantum optimal control on molecular systems. Our approach constrains pulse shapes to linear combinations of a fixed number of experimentally relevant pulse functions. Quantum optimal control is obtained by maximizing a multi-target fitness function using genetic algorithms.

Objective: To estimate, according to the states of disease (remission or relapse) and her level of progression (EDSS), the cost of treatment of Multiple Sclerosis (MS) in Colombia.

Methods: From the perspective of the third payer, a cost study of MS was performed using two-way estimation techniques: a) "Top down" to estimate the costs during relapses from clinical registers of 304 patients; b) "bottom-up" to estimate the cost in remission from a questionnaire (Kobelt 2006) applied to 137 patients, located in different regions of Colombia.

Results: The mean of patient's age was 43,7 years and 73% of those were women.

Communication: Conditions for one-photon coherent phase control in isolated and open quantum systems.

Coherent control of observables using the phase properties of weak light that induces one-photon transitions is considered. Measurable properties are shown to be categorizable as either class A, where control is not possible, or class B, where control is possible. Using formal arguments, we show that phase control in open systems can be environmentally assisted.
