Remote-controlled vascular interventional robots (RVIRs) are being developed to increase the accuracy of surgical operations and reduce the number of occupational risks sustained by intervening physicians, such as radiation exposure and chronic neck/back pain. However, complex control of the RVIRs improves the doctor's operation difficulty and reduces the operation efficiency. Furthermore, incomplete sterilization of the RVIRs will increase the risk of infection, or even cause medical accidents. In this study, we introduced a novel method that provides higher operation efficiency than a previous prototype and allows for complete robot sterilization...

Remote-controlled vascular interventional robots (RVIRs) are being developed to increase the overall accuracy of surgical operations and reduce the occupational risks of intervening physicians, such as radiation exposure and chronic neck/back pain. Several RVIRs have been used to operate catheters or guidewires accurately. However, a lack of cooperation between the catheters and guidewires results in the surgeon being unable to complete complex surgery by propelling the catheter/guidewire to the target position...

BACKGROUND AND OBJECTIVE: Fufang Danshen formula, a famous Chinese patent medicine containing Salvia miltiorrhiza, Panax notoginseng and borneol, has been widely used in the treatment of coronary heart disease. The application is restricted by low bioavailability partly due to Panax notoginseng saponins (PNS) instability and low in vivo absorption. Thus, adhesive pellets were developed to improve bioavailability. The objectives of the present study were to evaluate the adhesive preparation by describing PNS's plasma pharmacokinetics in vivo and compare adhesive micro pills with normal preparation...

The thermal reactivity of the heteronuclear metal-oxide cluster cations [XAlO4 ].+ (X=V, Nb, and Ta) towards methane has been studied by using mass spectrometry in conjunction with quantum mechanical calculations. Experimentally, a hydrogen-atom transfer (HAT) from methane is mediated by all the three oxide clusters at ambient conditions. However, [VAlO4 ].+ is unique in that this cluster directly transforms methane into formaldehyde. The absence of this reaction for the Nb and Ta analogues demonstrates a striking doping effect on the chemoselectivity in the conversion of methane...

Solvothermal reactions of AgI with the vulcanization accelerator 2,2'-dibenzothiazolyl disulfide and hydroiodic acid in alcohols afford two hybrid iodoargentates with one-dimensional structures, namely (Et2 mbt)[Ag2 I3 ] (1, Hmbt = 2-mercaptobenzothiazole) and {(Hmbt)[AgI]}n (2). The syntheses of both 1 and 2 involve unprecedented multiple in situ reactions. Specifically, a simultaneous disulfide bond cleavage, N and S donor atoms bialkylation, and self-assembly reaction lead to 1 that contains a discrete N,S-biethylated cation (Et2 mbt)+ and a rare inorganic (Ag2 I3 )- anionic chain, while a simultaneous disulfide bond cleavage, N-protonation and self-assembly reaction affords 2 which features zwitterionic Hmbt molecules coordinating with the opposite side Ag atoms of a neutral inorganic (AgI)n chain via forming Ag-S coordination bonds...

Specific antibodies are essential for the immune detection of small molecule contaminants. In the present study, the heavy and light variable regions (V(H )and V(L)) of the immunoglobulin genes from a hybridoma secreting a chloramphenicol (CAP)-specific monoclonal antibody (mAb) were cloned and sequenced. In addition, the light and heavy chains obtained from the monoclonal antibody were separated using SDS-PAGE and analyzed using Orbitrap mass spectrometry. The results of DNA sequencing and mass spectrometry analysis were compared, and the V(H) and V(L) chains specific for CAP were determined and used to construct a single-chain variable fragment (scFv)...

The reactions between methane and niobium oxide cluster cations were studied and compared to those employing vanadium oxides. Hydrogen atom abstraction (HAA) reactions were identified over stoichiometric (Nb2O5)N(+) clusters for N as large as 14 with a time-of-flight mass spectrometer. The reactivity of (Nb2O5)N(+) clusters decreases as the N increases, and it is higher than that of (V 2O5)N(+) for N ≥ 4. Theoretical studies were conducted on (Nb2O5)N(+) (N = 2-6) by density functional calculations. HAA reactions on these clusters are all favorable thermodynamically and kinetically...

Epigallocatechin‑3‑gallate (EGCG) is an active and major constituent of green tea. As a non‑nucleoside inhibitor of DNA methylation, EGCG is able to inhibit the hypermethylation of newly synthesised DNA, resulting in the reversal of hypermethylation and recovery in expression of the silenced genes. Reversion‑inducing cysteine‑rich protein with Kazal motifs (RECK) is a novel tumour suppressor gene, which negatively regulates matrix metalloproteinases, and inhibits tumour invasion, angiogenesis and metastasis...

Mainstream theories about decision-making under risk suggest that risky decisions are made by choosing the option that offers the highest mathematical expectation. The present event-related potentials (ERPs) study investigated the neurocognitive mechanisms underlying risky choice by contrasting a preferential choice task with an expected value choice task. The ERP data revealed that (1) the computational difficulty, which would be expected to influence a compensatory process, affected the slow wave only when participants were forced to choose the option with the highest expectation; and that (2) the difference in the minimum outcome dimension between two options, which would be expected to be influential in a heuristic process, affected the P300 and slow wave when participants were asked to choose the preferred option...

Glucose-6-phosphate isomerase (GPI) (EC can act as a myofibril-bound serine proteinase (MBSP) inhibitor (MBSPI) in fish. In order to better understand the biological information of the GPI and its functional domain for inhibiting MBSP, the cDNA of GPI was cloned from crucian carp (Carassius carassius) with RT-PCR, nested-PCR and 3'-RACE. The result of sequencing showed that the GPI cDNA had an open reading frame of 1662bp encoding 553 amino acid residues. After constructing and comparing the three-dimensional structures of GPI and MBSP, the middle fragment of crucian carp GPI (GPI-M) was predicted as a functional domain for inhibiting MBSP...
