Henry R Allen, Mariya Ptashnyk
The plant hormones brassinosteroid (BR) and gibberellin (GA) have important roles in a wide range of processes involved in plant growth and development. In this paper we derive and analyse new mathematical models for the BR signalling pathway and for the crosstalk between the BR and GA signalling pathways. To analyse the effects of spatial heterogeneity of the signalling processes, along with spatially-homogeneous ODE models we derive coupled PDE-ODE systems modelling the temporal and spatial dynamics of molecules involved in the signalling pathways...

Carbon-based nanomaterials (CBNs) were described as nanomaterials possessing abilities of plant growth regulators. Here, we investigated the effects of long-term exposure of multi-walled carbon nanotubes (MWCNTs) on the growth of three important crops (barley, soybean, corn). The cultivation of all tested species was carried in hydroponics supplemented with 50µg/ml of MWCNTs. After 20 weeks of continuous exposure to the nanomaterials, no significant toxic signs on plant development were observed. Several positive phenotypical changes were recorded in addition to the enhancement of photosynthesis in MWCNTs-exposed crops...

Quantum dot (QD) solids represents a new type of condensed matter that is highly relevant from both fundamental and applied points of view. The properties of QD solids are qualitatively different from those of the traditional solids, and their unique characteristics give rise to promising applications. The combination of quantum confinement in individual QDs with macroscopic scale of the whole material leads to novel features of electronic excitations (excitons) and charge transfer processes, which are of great interest for optoelectronic applications...

INTRODUCTION: Evidence-based practice (EBP) is the conscientious, explicit and judicious use of the current evidence in clinical decision making. The physiotherapy profession has expressed a commitment to the development and use of evidence. However, very little is known about the extent to which EBP is integrated in physiotherapy curricula in India. The purpose of this study was to describe integration of EBP in Indian physiotherapy programs. METHODS: An observational study was conducted where a review of curricula of all Health Science Universities (HSU) in India, offering an undergraduate (UG) and post-graduate (PG) degree program in physical therapy was conducted using a data abstraction sheet...

Hepatopulmonary syndrome (HPS) is a severe complication of advanced liver disease associated with an extremely poor prognosis. HPS is diagnosed in 4-47% of patients with cirrhosis and in 15-20% of candidates for liver transplantation. In addition, severe hypoxia is associated with a high risk of complications of liver transplantation (a 30% chance during the first 90 days) and increases the gap between transplantation and improving arterial oxygenation. The pathogenesis of HPS is not fully understood, and no effective pharmacological treatment has been developed yet...

Monitoring voltage dynamics in defined neurons deep in the brain is critical for unraveling the function of neuronal circuits, but is challenging due to the limited performance of existing tools. In particular, while genetically encoded voltage indicators have shown promise for optical detection of voltage transients, many indicators exhibit low sensitivity when imaged under two-photon illumination. Previous studies thus fell short of visualizing voltage dynamics in individual neurons in single trials. Here, we report ASAP2s, a novel voltage indicator with improved sensitivity...

Proteomics technology aims to map the protein landscapes of biological samples, and it can be applied to a variety of samples, including cells, tissues, and body fluids. Because the proteins are the main functional molecules in the cells, their levels reflect much more accurately the cellular phenotype and the regulatory processes within them than gene levels, mutations, and even mRNA levels. With the advancement in the technology, it is possible now to obtain comprehensive views of the biological systems and to study large patient cohorts in a streamlined manner...

Penetration depth of near infrared laser radiation to costal cartilage is controlled by the tissue absorption and scattering and it is the critical parameter to provide the relaxation of mechanical stress throughout the whole thickness of cartilage implant. To enhance the penetration for the laser radiation on 1.56 μm the optical clearing solutions of glycerol and fructose of various concentrations are tested. The effective and reversible tissue clearance was achieved. However, the increasing absorption of radiation should be concerned: 5-8(ᴼ) C increase of tissue temperature was detected...

BACKGROUND AND OBJECTIVES: Resistant hypertension is an important problem; nearly half of diagnosed hypertensives are not controlled to target blood pressure levels, and approximately 90% of strokes occur among patients with resistant hypertension. Primary aldosteronism accounts for approximately 20% of resistant hypertension, but the role of secondary hyperaldosteronism in resistant hypertension is seldom considered. We assessed the effects of eplerenone in patients with hypertension and either primary or secondary hyperaldosteronism...

Vesicle-templated nanocapsules have emerged as a viable platform for diverse applications. Shell thickness is a critical structural parameter of nanocapsules, where the shell plays a crucial role providing mechanical stability and control of permeability. Here we used small-angle neutron scattering (SANS) to determine the thickness of freestanding and surfactant-stabilized nanocapsules. Despite being at the edge of detectability, we were able to show the polymer shell thickness to be typically 1.0 ± 0.1 nm, which places vesicle-templated nanocapsules among the thinnest materials ever created...

Thirty-two muskrats (Ondatra zibethicus) were captured for surveillance of avian influenza virus in wild waterfowl and mammals near Lake Chany, Western Siberia, Russia. A/muskrat/Russia/63/2014 (H2N2) was isolated from an apparently healthy muskrat using chicken embryos. Based on phylogenetic analysis, the hemagglutinin and neuraminidase genes of this isolate were classified into the Eurasian avian-like influenza virus clade and closely related to low pathogenic avian influenza viruses (LPAIVs) isolated from wild water birds in Italy and Sweden, respectively...

This work addresses the challenge of creating hollow nanocapsules with a controlled quantity of encapsulated molecules. Such nanocontainers or nanorattle-like structures represent an attractive platform for building functional devices, including nanoreactors and nanosensors. By taking advantage of the electrostatic attraction between oppositely charged cargo molecules and the surface of the templating bilayer of catanionic vesicles, formed by mixing single-tailed cationic and anionic surfactants, we were able to achieve a substantial increase in the local concentration of molecules inside the vesicle-templated nanocapsules...

From therapeutic point of view, it is often beneficial to enhance the expression of certain enzymes whose low expression is responsible for the observed ailment. Small molecules as activators of several enzymes have great biological potential as anti-microbial and anti-cancer agents, for the treatment of diabetes, obesity, metabolic disorders, and for the treatment of neurological disorders including Alzheimer's disease. This review covers patents describing small molecules as activators, and provides structural leads for the design of even more potent activators...
