Detecting Pb in aqueous environment and live cells by amphiphilic pillar[5]arene-assembled supramolecular sensor based on host-guest charge transfer mechanism.

Water-soluble fluorescent chemosensors for lead ion are highly desirable in environmental detection and bioimagery. Based on a water-soluble pillar[5]arene WP5 and imidazolium terminal functionalized 2,2'-bibenzimidazole derivative BIHB, we report a host-guest charge transfer assembly BIHB-2WP5 for sensitive and selective detection of Pb in pure aqueous media. As a result of its high electron-rich cavity, WP5 can bind electron-deficiency guest BIHB with various host/guest stoichiometry to easily tune the microtopography of assembly from nanoparticle to nanocube.

Molecular mechanism of salinity and waterlogging tolerance in mangrove .

Mangrove forests are colloquially referred to as "Earth's kidneys" and serve many important ecological and commercial functions. Salinity and waterlogging stress are the most important abiotic stressors restricting the growth and development of mangroves. is the greatest latitudinally-distributed salt mangrove species in China.

Physiological and transcriptomic analysis of the mangrove species Kandelia obovata in response to flooding stress.

Flooding stress on mangroves is growing continually with rising sea level. In this study, the physiology and transcriptome of the mangrove species Kandelia obovata under flooding stress were analyzed. With increasing inundation time, malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), soluble sugar (SS), soluble protein (SP), and proline (Pro) content declined, while peroxidase (POD) and ascorbate peroxidase (APX) activity rose significantly.

Ion recognition properties of 2,2'-bibenzimidazole regulated by ammonium-modified pillar[5]arenes.

With the increasing issues of environmental degradation and health problem, the selective detection of toxic ions has attracted considerable attention from researchers. Chemical fluorescent sensors with the advantages of facile operation, high sensitivity, rapid response, and easy visualization are emerging as powerful detection tools towards ions. However, the selective recognition of ions is always hindered by the presence of other interfering substances.

Role of exogenous abscisic acid in freezing tolerance of mangrove Kandelia obovata under natural frost condition at near 32N.

Background: Mangroves possess substantial ecological, social, and economic functions in tropical and subtropical coastal wetlands. Kandelia obovata is the most cold-resistance species among mangrove plants, with a widespread distribution in China that ranges from Sanya (18° 12' N) to Wenzhou (28° 20' N). Here, we explored the temporal variations in physiological status and transcriptome profiling of K.

IsoSeq and RNA-Seq analyses uncover the molecular response of Dalbergia odorifera T. Chen to low temperature.

In previous studies, we found young plants propagated from acclimated D. odorifera T. Chen trees displayed increased cold tolerance.

Integrative Analyses of Transcriptomics and Metabolomics in Sex Differentiation of Mulberry Flowers.

Sex determination and sex differentiation of plants are important physiological processes of plant development. Mulberry ( L.) is an important economic tree being cultivated in sericulture countries, and mulberry leaf is commonly used for sericulture.

Learning to Extract Building Footprints From Off-Nadir Aerial Images.

Extracting building footprints from aerial images is essential for precise urban mapping with photogrammetric computer vision technologies. Existing approaches mainly assume that the roof and footprint of a building are well overlapped, which may not hold in off-nadir aerial images as there is often a big offset between them. In this paper, we propose an offset vector learning scheme, which turns the building footprint extraction problem in off-nadir images into an instance-level joint prediction problem of the building roof and its corresponding "roof to footprint" offset vector.

RNA-seq and phytohormone analysis reveals the culm color variation of Munro.

Background: The clumping bamboo Munro, known as "green bamboo", is famous for its edible bamboo shoots and fast-growing timber. The green and yellow striped-culm variety, named f. W.

The rhizosphere effect of native legume Albizzia julibrissin on coastal saline soil nutrient availability, microbial modulation, and aggregate formation.

In the coastal zones, numerous ecological shelterbelt projects were conducted to protect against natural hazards. However, it is still not fully understood whether phytoremediation with native legume Albizzia julibrissin plantation can improve saline soil structural development or microbial community structure. In this study, a field experiment was conducted to investigate the responses of rhizosphere soil salinity, nutrients, bacterial community, and aggregate structure to A.

The complete chloroplast genome sequence of (Bambusoideae).

is an excellent sympodial bamboo species, which is cultivated for its shoots in some parts of China. Here, we sequenced and reported the complete chloroplast genome of for the first time. The complete chloroplast genome sequence of was generated by assembly using whole-genome next-generation sequencing.

Nutrient uptake and assimilation in fragrant rosewood (Dalbergia odorifera T.C. Chen) seedlings in growing media with un-composted spent mushroom residue.

The purpose of this study was to detect nutrient uptake and assimilation in woody plants subjected to growing media with some peat replaced by spent mushroom residue (SMR). Fragrant rosewood (Dalbergia odorifera T.C.

Development of an Autonomous Unmanned Aerial Manipulator Based on a Real-Time Oriented-Object Detection Method.

Autonomous Unmanned Aerial Manipulators (UAMs) have shown promising potential in mobile 3-dimensional grasping applications, but they still suffer from some difficulties impeding their board applications, such as target detection and indoor positioning. For the autonomous grasping mission, the UAMs need ability to recognize the objects and grasp them. Considering the efficiency and precision, we present a novel oriented-object detection method called Rotation-SqueezeDet.

Nab-paclitaxel plus S-1 as first-line followed by S-1 maintenance for advanced pancreatic adenocarcinoma: a single-arm phase II trial.

Purpose: We conducted a single-arm prospective phase II study to determine the efficacy and safety of the first-line treatment of advanced pancreatic cancer with nab-paclitaxel and S-1 followed by S-1 maintenance therapy.

Methods: Nab-paclitaxel was administered intravenously on days 1 and 8 at 120 mg/m. S-1 at 120 mg/day (for surface area ≥ 1.

Response of submerged plant (Vallisneria spinulosa) clones to lead stress in the heterogenous soil.

In order to evaluate risk spreading among clones and antioxidant defence response of clonal ramets, turions of Vallisneria spinulosa, the dominant clonal plant of the submerged plant community in most of the lakes in Middle and Lower Reaches of Yangtze Rive, China, were planted in the heterogeneous soils contaminated with 40 and 160 microg g(-1) Pb (dry weight) in a greenhouse. After 100 d, the ranking order of tissue Pb concentrations in organs of the ortets (parental plants) was root>turion>rhizome>leaf, but that of tissue Pb quantities was leaf>turion>rhizome>root, due to their different biomass. Some of Pb was transferred from the ortets exposed in the Pb-supplied soil to leaves of the offspring growing in the favorable patch through rhizome (connective organ).
