Oleosins are the most abundant proteins in the monolipid layer surrounding neutral storage lipids that form oil bodies in plants. Several lines of evidence indicate that they are physiologically important for the maintenance of oil body structure and for mobilization of the lipids stored inside. Rice has six oleosin genes in its genome, the expression of all of which was found to be responsive to abscisic acid (ABA) in our examination of mature embryo and aleurone tissues. The 5'-flanking region of OsOle5 was initially characterized for its responsiveness to ABA through a transient expression assay system using the protoplasts from suspension-cultured rice cells...

Much attention has been paid to the availability of arsenic (As) in soils, while few studies were carried out on the comparison between the dry and flooded soils using different methods. In this study, chemical sequential extraction and diffusive gradients in thin films (DGT) techniques were employed to study the availability of As in soils amended with a range of exogenous As followed by one-year incubation under dry and flooded conditions, respectively. The results showed that the proportions of available solid As pools, including non-specifically adsorbed As (F1) and specifically adsorbed As (F2), had consistent increases with the increase of As amendment...

Coping with the increasing environmental issues, niobium oxyfluoride (Nb3O7F) as a novel semiconductor is a kind of promising photocatalyst due to its outstanding electronic and optoelectrinic properties. However, the photocatalytic performance of Nb3O7F is restricted in practical application due to its weak optical absorption and low carrier separation. In this work, novel Nb3O7F/WS2 hybrid nanocomposites with superior optical absorption and photocatalytic activity have been successfully synthesized by a facile two-step sol-hydrothermal technique...

Long-lasting persistent luminescent nanoparticles (PLNPs) with efficient near-infrared (NIR) emission have emerged as a new generation of probes for in vivo optical bioimaging owing to their advantages of zero-autofluorescence benefited from the self-sustained emission after excitation, deep penetration depth, and a high signal-to-noise ratio. However, most of the PLNPs are charged by ultraviolet (UV) or visible light, remarkably limiting their applications for in vivo long-term bioimaging. Here we demonstrate 980 nm laser activated upconversion-PLNPs (UC-PLNPs) with efficient NIR emission...

Cell nanoencapsulation provides a chemical tool for the isolation and protection of living cells from harmful, and often lethal, external environments. Although several strategies are available to form nanometric films, most methods heavily rely on time-consuming multistep processes and are not biocompatible. Here, the interfacial supramolecular self-assembly and film formation of ferric ions (Fe(III) ) and tannic acid (TA) in biphasic systems is reported, where Fe(III) and TA come into contact each other and self-assemble across the interface of two immiscible phases...

Epigenetics play a central role in the regulation of many important cellular processes, and dysregulations at the epigenetic level could be the source of serious pathologies, such as neurological disorders affecting brain development, neurodegeneration, and intellectual disability. Despite significant technological advances for epigenetic profiling, there is still a need for a systematic understanding of how epigenetics shapes cellular circuitry, and disease pathogenesis. The development of accurate computational approaches for analyzing complex epigenetic profiles is essential for disentangling the mechanisms underlying cellular development, and the intricate interaction networks determining and sensing chromatin modifications and DNA methylation to control gene expression...

A 31-year-old woman with a 15-year history of Takayasu's arteritis (TA) and a 13-year history of Hashimoto's thyroiditis presented with hematochezia. She received a diagnosis of Sjögren's syndrome at 1 month before her visit to Kyungpook National University Medical Center. Her colonoscopic findings were compatible with a diagnosis of ulcerative colitis (UC). She was treated with oral mesalazine, and her hematochezia symptoms subsequently disappeared. The coexistence of UC and TA has been reported; however, reports on the coexistence of UC and Sjögren's syndrome, or of UC and Hashimoto's thyroiditis are rare...

Biotic interactions underlie ecosystem structure and function, but predicting interaction outcomes is difficult. We tested the hypothesis that biotic interaction strength increases toward the equator, using a global experiment with model caterpillars to measure predation risk. Across an 11,660-kilometer latitudinal gradient spanning six continents, we found increasing predation toward the equator, with a parallel pattern of increasing predation toward lower elevations. Patterns across both latitude and elevation were driven by arthropod predators, with no systematic trend in attack rates by birds or mammals...

Introduction: Genetic variants associated with nicotine dependence have previously been identified, primarily in European-ancestry populations. No genome-wide association studies (GWAS) have been reported for smoking behaviors in Hispanics/Latinos in the U.S. and Latin America, who are of mixed ancestry with European, African, and American Indigenous components. Methods: We examined genetic associations with smoking behaviors in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) [N=12,741 with smoking data, 5,119 ever smokers], using ~2...

Chemical systems find similarities in different sociological and biological processes where the entities compete or cooperate for a favourable outcome. This stochastic innovation mechanism of structural and functional adaptation especially in catalysis is based on factors like abundance of substrates, stability of transition state and structural/functional attributes of catalysts. Here we show how catalytic fibres of two self-sorting hydrogelators compete for the same resources to bring down the overall selectivity of Mannich reaction...

Using a seed layer-free hydrothermal method, ZnO nanorods (NRs) were deposited on ST-cut quartz surface acoustic wave (SAW) devices for ammonia sensing at room temperature. For a comparison, a ZnO film layer with a thickness of 30 nm was also coated onto an ST-cut quartz SAW device using a sol-gel and spin-coating technique. The ammonia sensing results showed that the sensitivity, repeatability and stability of the ZnO NR-coated SAW device were superior to those of the ZnO film-coated SAW device due to the large surface-to-volume ratio of the ZnO NRs...

Barium-strontium titanate (BST) Ba0.6Sr 0.4 TiO3 and lanthanum-lithium titanate (LLT) La0.5Li0.5TiO3 nanopowders and thin films have been obtained via the modified Pechini route. Polyesterification and complexation processes of gel formation have been examined. Hypothetical models of coordinative polymers formed in sol-gel system have been suggested. It has been shown that BST and LLT solid solutions form in one step at relatively low temperature. X-ray diffraction confirms that the final products, which are single phases and have cubic shape, are formed at 600 and 700 °C for BST and LLT respectively...

Kappa-carrageenan (kC) is a polyelectrolyte biopolymer that forms gels if the kC concentration, the salt and the temperature are adequately chosen. Actually, under certain conditions, kC gels release water in a process called syneresis. In this contribution, the syneresis of gels containing 2g/L of kC has been studied as a function of potassium chloride concentration [KCl]. The syneresis decreases if the [KCl] is increased in the biopolymer solution (sol) before the gelation but increases if the [KCl] is increased after gelation by immersing the gels in KCl solution...

Flexible batteries are essential for wearable electronic devices. To meet practical application, it is needed to be mechanically robust and stable. However, strong or multiple bending may sever the interfacial contact between electrode and electrolyte, causing capacity fading or even battery failure. Herein we present a new "cooling-recovery" concept for flexible batteries, which involves a temperature-sensitive sol-gel transition behavior of the thermoreversible polymer hydrogel electrolyte. Once batteries suffered from strong mechanical stresses, a simple cooling process can refresh the electrode-electrolyte interface...

Supramolecular hydrogel formed by the self-assembly of therapeutic agents have received considerable attention due to its high drug payload, carrier-free features. Herein, we constructed a dexamethasone sodium phosphate (Dex) supramolecular hydrogel in combination of Dex and calcium ion (Ca(2+)) and further demonstrated its therapeutic efficacy in the control of ocular inflammation. The developed supramolecular hydrogel was thoroughly characterized by rheology, TEM, FTIR and XRD. Calcium ions and Dex concentration had markedly influence on the sol-gel transition behavior of hydrogel and the proposed Dex supramolecular hydrogel displayed thixotropic property...

BACKGROUND & AIM: Esophagogastroduodenoscopy (EGD) is commonly used to detect upper gastrointestinal (GI) neoplasms. However, there is little evidence that longer examination time increases rate of detection of upper GI neoplasia. We investigated the association between length of time spent performing a normal screening EGD and rate of neoplasm detection. METHODS: We performed a retrospective analysis of data from 111,962 subjects who underwent EGD as part of a comprehensive health-screening program from January 2009 to December 2015 in Korea...
