STIM1 and Orai1 regulate Ca microdomains for activation of transcription.

Since calcium (Ca) regulates a large variety of cellular signaling processes in a cell's life, precise control of Ca concentrations within the cell is essential. This enables the transduction of information via Ca changes in a time-dependent and spatially defined manner. Here, we review molecular and functional aspects of how the store-operated Ca channel Orai1 creates spatiotemporal Ca microdomains. The architecture of this channel is unique, with a long helical pore and a six-fold symmetry. Energetic barr...

Inspired by natural ciliary movement, artificial cilia systems have recently been developed to transport microparticles and target biomolecules by the external stimuli-induced bend and twist. However, the directional transportation of cargo meets major challenge. Here we present an artificial asymmetric cilia array of dielectric elastomer and realize the cargo directional transportation under alternating-current (AC) electric field. Such dielectric elastomer is composed of elastomer matrix and dielectric ba...


Control on Dimensions and Supramolecular Chirality of Self-Assemblies through Light and Metal Ions.

Precise control over helical chirality and dimensions of molecular self-assemblies, a remaining challenge for both chemists and materials scientists, is the key to manipulate the property and performance of supramolecular materials. Herein, we report that a cholesterol-azopyridine conjugate could self-assemble into organogels with photo-controllable dimensional transition from 2D microbelts to 1D nanotubes and finally to 0D nanoparticles. The E/Z-Photoisomerization of the 4-azopyridine unit is the major dri...

Pareto Optimality in Multilayer Network Growth.

We model the formation of multilayer transportation networks as a multiobjective optimization process, where service providers compete for passengers, and the creation of routes is determined by a multiobjective cost function encoding a trade-off between efficiency and competition. The resulting model reproduces well real-world systems as diverse as airplane, train, and bus networks, thus suggesting that such systems are indeed compatible with the proposed local optimization mechanisms. In the specific case...

It was also found that the as-prepared autofluorescent protein hydrogel possessed rapid and repetitive self-healing capability. Without any external stimulus, more than 90% recovery of the ...

Biosynthesis and accumulation of 20-hydroxyecdysone in individual male and female spinach plants during the reproductive stage.

The steroid 20-hydroxyecdysone (20E) is a major component of phytoecdysteroid in plants and may play a defensive role against insect pests in higher plants. In spinach, the biosynthesis and accumulation of 20E have been investigated during the vegetative stage; however, these processes have not been clearly studied during the reproductive stage, particularly in male and female individuals. In this study, we analyzed the level and distribution of 20E in individual male and female spinach plants during the re...

Deep soils modify environmental consequences of increased nitrogen fertilizer use in intensifying Amazon agriculture.

Agricultural intensification offers potential to grow more food while reducing the conversion of native ecosystems to croplands. However, intensification also risks environmental degradation through emissions of the greenhouse gas nitrous oxide (NO) and nitrate leaching to ground and surface waters. Intensively-managed croplands and nitrogen (N) fertilizer use are expanding rapidly in tropical regions. We quantified fertilizer responses of maize yield, NO emissions, and N leaching in an Amazon soybean-maize...

A combination of microwave irradiation and flow chemistry has been described as a promising smart and hyphenated technology that can fuse and synergize the benefits of the techniques. The cells and tissues of all living organisms promote a huge number of bioorganic reactions that occur as flow systems and not the batch-type conditions typically used by chemists and biotechnologists. Microwave-assisted chemical conversion carried out in continuous flow mode with micro- or meso-channel reactors can offer sign...

Episodic future thinking and grocery shopping online.

Grocery shopping shapes the home food environment, which can contribute to the development of obesity. Episodic future thinking (EFT) helps adults make healthier decisions by initiating prospective thinking, which guides one to forego smaller immediate rewards in favor of larger delayed rewards. EFT could help parents improve grocery purchases thereby improving the home food environment and family eating behaviors. The effect of EFT on food shopping was evaluated in two studies with mothers who were overwei...

TDCPP protects cardiomyocytes from HO-induced injuries via activating PI3K/Akt/GSK3β signaling pathway.

Tris (1, 3-dichloro-2-propyl) phosphate (TDCPP) is a major type of organophosphorus flame retardants, and long-term exposure to TDCPP to normal cells or tissues under physiological conditions can induce toxic effects. But how TDCPP leads to the adverse effects is not yet clear, and the effect of TDCPP under pathological conditions such as reactive oxygen species assault is not well understood. The present study aimed to explore the potential effect of TDCPP against HO-induced oxidative stress in H9c2 cardio...

Consumers' evaluation of imported organic food products: The role of geographical distance.

Country-of-origin (COO) effects and consumer evaluation of organic food products are rarely studied in combination. The aim of this study was therefore to investigate organic consumers' preferences for imported organic food products from different origins and the underlying reasons for these preferences, including how consumers' COO preferences depend on the geographical distance to the COO. We employed a multi-method, qualitative approach consisting of in-store interviews (N = 255) and focus groups (si...

Inhibition of STIM1-mediated SOCE as a novel strategy for the treatment of acquired imatinib-resistant GIST.

Imatinib has revolutionized the treatment of gastrointestinal stromal tumors (GIST); however, primary and secondary resistance to imatinib is still a major cause of treatment failure. Multiple mechanisms are involved in this progression. In the present study, we reported a novel mechanism for the acquired resistance to imatinib, which was induced by enhanced Ca2 influx via stromal-interacting molecule 1 (STIM1)-mediated store-operated Ca2 entry (SOCE). We found that the STIM1 expression level was related to...

Gain-of-function mutations in STIM1 and ORAI1 causing tubular aggregate myopathy and Stormorken syndrome.

Calcium (Ca) is a key regulator for a large number of cellular functions in all kinds of cells, and small disturbances of Ca homeostasis can severely compromise normal physiology in various tissues and organs. A major mechanism controlling Ca homeostasis is store-operated Ca entry (SOCE), which relies on the concerted action of the reticular Ca sensor STIM1 and the plasma membrane Ca channel ORAI1. Gain-of-function mutations in the respective genes induce excessive Ca entry, and cause tubular aggregate myop...

Calcium stores regulate excitability in cultured rat hippocampal neurons.

Extracellular calcium ions support synaptic activity, but also reduce excitability of central neurons. In the present study, the effect of calcium on excitability was explored in cultured hippocampal neurons. CaCl injected by pressure in the vicinity of a neuron that is bathed only in MgCl as the main divalent cation, caused a depolarizing shift in action potential threshold and a reduction in excitability. This effect was not seen if the intracellular milieu consisted of Cs instead of K-gluconate as the ma...

CdS quantum dots/C60 tubular micromotors with chemical/multi-light-controlled propulsion and "on-the-fly" acceleration capabilities are described. "In-situ" growth of CdS quantum dots on the outer fullerene layer impart them with light-responsive properties in connection to inner Pt, Pd or MnO2 layers. This is the first time that visible-light is used to drive bubble propelled tubular micromotors. The micromotors exhibit broad absorption range from 320 to 670 nm and can be wirelessly-controlled by modulatin...

Smart pH-sensitive Nanogels for Controlled Release in Acidic Environment.

The encapsulation of therapeutic compounds into nanosized delivery vectors has become an important strategy to improve efficiency and reduce side-effects in drug delivery applications. Here, we report the synthesis of pH-sensitive nanogels, which are based on the monomer N-[(2,2-dimethyl-1,3-dioxolane)methyl]acrylamide (DMDOMA) bearing an acid cleavable acetal group. Degradation studies revealed that these nanogels hydrolyze under acidic conditions and degrade completely, depending on the crosslinker, but a...

Exercise prevents HFD- and OVX-induced type 2 diabetes risk factors by decreasing fat storage and improving fuel utilization.

Previous studies suggest that the loss of estrogens increase one's risk for type 2 diabetes (T2D), and combining the loss of estrogens with a high-fat diet (HFD) poses an even greater risk for T2D. The extent to which exercise can ameliorate the deleterious effects of estrogen loss combined with a HFD and the molecular mechanisms accounting for the whole body changes is currently unknown. Therefore, we fed female Wistar rats a standard diet or a HFD for 10 weeks. The rats fed the HFD were either ovariectom...

Addressing Multiple Resistive States of Polyoxovanadates: Conductivity as a Function of Individual Molecular Redox States.

The sustainable development of IT-systems requires a quest for novel concepts to address further miniaturization, performance improvement and energy efficiency of devices. The realization of these goals cannot be achieved without an appropriate functional material. Herein, we target the technologically important electron modification using single polyoxometalate (POM) molecules envisaged as smart successors of materials that are implemented in today's complementary metal-oxide-semiconductor (CMOS) technolog...

Precise Localization of Multiple Noncooperative Objects in a Disordered Cavity by Wave Front Shaping.

Complicated multipath trajectories of waves in disordered cavities cause object localization to be very challenging with traditional ray-tracing approaches. Yet it is known that information about the object position is encoded in the Green's function. After a calibration step, traditional time-reversal approaches retrieve a source's location from a broadband impulse response measurement. Here, we show that a nonemitting object's scattering contribution to a reverberant medium suffices to localize the object...

Snap-Buckling Motivated Controllable Jumping of Thermo-Responsive Hydrogel Bilayers.

Responsive hydrogel actuators have promising applications in diverse fields. Most hydrogel actuators are limited by slow actuation or shape transformations. This work reports on snap-buckling motivated jumping of thermoresponsive hydrogel bilayers. The bilayers are composed of poly(NIPAM-co-DMAPMA)/clay hydrogel with different lower critical solution temperatures (LCST) in each layer, and thus undergoes slow reversible curling/uncurling at temperature changes. The gels are adhesive to numerous materials inc...
