Fabrication of a Microfluidic-Based Device Coated with Polyelectrolyte-Capped Titanium Dioxide to Couple High-Performance Liquid Chromatography with Inductively Coupled Plasma Mass Spectrometry for Mercury Speciation.

Mercury (Hg) is a toxic element which impacts on biological systems and ecosystems. Because the toxicity of Hg species is highly dependent on their concentration levels and chemical forms, the sensitive identification of the chemical forms of Hg-i.e.

Telomere-to-telomere genome assembly of melon ( L. var. ) provides a high-quality reference for meta-QTL analysis of important traits.

Melon is an important horticultural crop with extensive diversity in many horticultural groups. To explore its genomic diversity, it is necessary to assemble more high-quality complete genomes from different melon accessions. Meanwhile, a large number of QTLs have been mapped in several studies.

Inflammatory cytokines and two subtypes of breast cancer: A two-sample mendelian randomization study.

Background: Breast cancer is a common cancer type that leads to cancer-related deaths among women. HER2-positive breast cancer, in particular, is associated with poor prognosis due to its high aggressiveness, increased risk of recurrence, and metastasis potential. Previous observational studies have explored potential associations between inflammatory cytokines and the risk of two breast cancer subtypes (HER2-positive and HER2-negative), but the results have been inconsistent.

Study on lightening of coal tar with metal oxide supported γ-AlO catalyst.

In this experiment, a fixed bed of pyrolysis was used to conduct pyrolysis with coal and a mixture of coal and catalyst, and the distribution and composition of tar products were studied. The pyrolysis of raw coal was carried out at different temperatures and at different constant temperature times, and the effects of pyrolysis temperature and constant temperature pyrolysis time on tar product formation from raw coal pyrolysis were studied. γ-AlO was used as the carrier, and 4 kinds of alkaline earth metal oxides (MgO, CaO, SrO, BaO), 3 kinds of subgroup metal oxides (FeO, CoO, NiO) and 5 kinds of VIII metal oxides (CrO, MnO, CuO, ZnO, MnO) were selected as active components.

Study on Mechanical Behavior of Hollow-Core Slab Bridge with Pinned Reinforcement.

Joints connect prefabricated hollow-core slabs, the key elements of force transmission of hollow-core slab bridges. The joints are easily damaged, which affects the integrity and safety of the hollow-core slab bridge. This paper uses MIDAS FEA NX finite element analysis software to simulate the deep hinge joint segment model, comparing and analyzing the finite element simulation analysis results with the test results, and proposes the critical parameters of the hinge joint interface and concrete damage plasticity.

Study on Load Transfer Mechanism of Local Curved Prestressed Hollow-Core Slab Bridge.

The assembled hollow-core slab bridge is the most widely used beam bridge in China. With the increasing traffic volume and traffic load in China, the joints of the hollow-core slab bridge are prone to damage. In this paper, a hollow-core slab bridge with locally curved prestressed tendons is proposed.

Impacts of stand density on diversity of understory plant and soil seed banks in a plantation.

Stand density is a critical factor impacting the diversity of understory plants. We analyzed the diversity of understory plants and soil seed banks, as well as their relationship by setting up three planting densities in a plantation, including low density (1575 trees·hm, D), medium (2474 trees·hm, D), and high (3550 trees·hm, D). It aimed to provide a scientific basis for the implementation of the multi-objective sustainable development of plantations.

Mitochondrial ATP synthase regulates corpus cavernosum smooth muscle cell function and .

Adenosine triphosphate (ATP) levels are closely associated with diabetes-related erectile dysfunction (DMED). Mitochondrial ATP synthase serves a key role in ATP production. The present study aimed to investigate the relationship between F-ATP synthase and DMED and .

Comparative analysis of volatile compounds in thirty nine melon cultivars by headspace solid-phase microextraction and gas chromatography-mass spectrometry.

The types and amounts of volatiles in the fruits of 39 melon cultivars were determined. We identified 146 volatiles, including 55 esters, 23 aldehydes, 30 alcohols, 15 ketones, 6 acids and 17 others. Ethyl acetate, (Z)-6-nonenal and 3,6-(E,Z)-nonadien-1-ol were the most three abundant volatiles (average content > 50 µg/kg FW).

Study on the Preparation of Plasma-Modified Fly Ash Catalyst and Its De⁻NO Mechanism.

Fly ash and bentonite were mixed in a certain proportion as raw materials to prepare a denitration catalyst. In previous studies, it has been concluded that fly ash-type catalysts can provide significant catalytic activity for denitrification after being modified with oxygen. In this study, the effect of plasma conditions on the denitration performance of the catalyst was investigated from the aspects of plasma modification power, modification time, and the flow rate of the gas.

Study on the NO removal efficiency of the lignite pyrolysis coke catalyst by selective catalytic oxidation method.

Selective catalytic oxidation (SCO) method is commonly used in wet denitration technology; NO after the catalytic oxidation can be removed with SO2 together by wet method. Among the SCO denitration catalysts, pyrolysis coke is favored by the advantages of low cost and high catalytic activity. In this paper, SCO method combined with pyrolysis coke catalyst was used to remove NO from flue gas.

Post-Operative Complications in Living Liver Donors: A Single-Center Experience in China.

The gap between the growing demand for available organs and the cadaveric organs facilitates the adoption of living donor liver transplantation. We retrospectively identified and evaluated the post-operative complications as per the modified Clavien classification system in 152 living liver donors at at the First Affiliated Hospital, College of Medicine, Zhejiang University between December, 2006 and June, 2014. Post-operative complications were observed in 61 patients (40.
