The aim of the present study was to investigate the effect of dexpanthenol on nerve healing following neurorrhaphy in lacerated peripheral nerves. A total of 30 mature Sprague Dawley rats were used. Surgical sciatic nerve dissection and repair was performed on an experimental group of 20 rats. The remaining 10 rats were designated as the control group. The experimental group was divided into 2 subgroups. The surgery + saline group (SSLE; n=10) was given 1 ml/kg 0.9% sodium chloride saline intraperitoneally. The surgery + dexpanthenol group (SDPL; n=10) rats were given 500 mg/kg/day dexpanthenol intraperitoneally. Histological evaluation of the sciatic nerve tissue revealed that the fibrosis score was significantly lower in the SDPL group than in the SSLE group (P<0.001). Electrophysiological evaluation of compound muscle action potential (CMAP) indicated that the CMAP level in the SDPL group was significantly higher than that of the SSLE group (P<0.001), and the CMAP latency period was lower in the SDPL group compared with the SSLE group (P<0.001). In addition, the SDPL group malondialdehyde level was significantly lower than that of the SSLE group (P<0.001). Functional evaluation with an inclined plane test revealed a significant difference between the SSLE (39.6 +/- 5.5 degrees) and SDPL (79.1 +/- 6.93 degrees) groups (P<0.001). Dexpanthenol was observed to have a positive effect on nerve tissue repaired with neurorrhaphy in a rat sciatic model of laceration-type injuries similar to those frequently encountered in the clinic. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5407-04-5, you can contact me at any time and look forward to more communication.

The additive drag reduction technology has wide application and high economic value in drag reduction of oilfield water injection system. With CTAC/NaSal (cetyltrimethyl ammonium chloride/sodium salicylate) aqueous solution as the research object, this paper explores the effects of oilfield water component on its rheological characteristics under the experimental condition of 10-60 degrees C, .1-1 000 s(-1), and 0.01-0.21 wt %. The experimental results reveal that the oil cannot inhibit the formation of shear-induced structure in the solution and strengthen the temperature resistance of the solution; NaHCO3 and CaCl2, two types of salts, have similar effects on rheological characteristics of the CTAC/NaSal solution. The solution viscosity increases first and then decreases with the increase of salt concentration. And the viscosity peak gradually moves to the left lower with the increase of temperature, which means that the salt tolerance of the solution decreases with the increase of temperature. Moreover, the Giesekus model has the best performance for describing the rheological characteristics of surfactant solutions. Within the experimental concentration range, the relative error is +/- 25%.

In preparing polymer capsules by vesicle templated emulsion polymerization, the initial size and morphology of the biomimetic vesicle template dictate the final size and morphology of the capsules. The presence of salts (NaCl, NaBr and LiCl) influences the size, dispersity (PDI) and morphology of dimethyldioctadecylammonium bromide or chloride (DODAX, X = Br-; or Cl-) vesicles, prepared via membrane extrusion. DODAX vesicles in pure water exhibit broad size distributions with PDI of 0.5 and 0.3 for DODAB and DODAC, respectively. Addition of salts in water before (pre-addition) and after (post addition) extrusion reduces the size and PDI of the vesicles significantly and results in various morphology investigated with cryo-TEM. It is observed that at low salt concentration (<= 0.5 mM) in pre-addition, DODAX exists as a nice quasi spherical unilamellar vesicle, suitable for vesicle templated polymerization whereas in post-addition of salt at any concentration, the morphology is dominated by structures not suitable for templating application. The information obtained here is crucial for vesicle templated emulsion polymerization and it will be shown that there is a relationship between vesicle template morphology and final polymer capsule morphology.

In this work, different electrochemical measurements were employed to investigate the electrochemical behavior of La(III) on W and liquid aluminum electrodes, respectively. In LiCl-KCl melts, the diffusion coefficients of La(III) on W electrode at different experimental temperatures were determined by chronopotentiometry. The cyclic voltammetry results obtained on liquid aluminum electrode revealed only one pair of redox signal corresponding to the formation of Al-La intermetallic compound in LiCl-KCl-LaCl3 melts. The diffusion coefficient of La atom on the liquid Al-La alloy electrode was evaluated by anodic chronopotentiometry at 973 K. The electrochemical extraction of La was realized by galvanostatic electrolysis on a liquid aluminum electrode in LiCl-KCl-LaCl3 melts at 973 K, and the phases of Al11La3 and Al were identified by XRD. The SEM images disclosed needlelike precipitates in alloy, and the element La mainly distribute in the needlelike precipitates. After electrolysis, the extraction efficiency of element La was evaluated to be 99.4%, indicates that the electrochemical extraction of lanthanum with the help of liquid aluminum cathode is feasible in practice.

The effect of adding D-fructose to simulated body fluid (SBF) on the corrosion behavior of AZ31 magnesium (Mg) alloy at 37 degrees C and at a pH of 7.4 was studied by potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), potentiostatic polarization and hydrogen (H 2 ) collecting techniques, Raman spectroscopy technique, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), X-ray photoelectron spectroscopy analysis (XPS) and Fourier transformed infrared (FTIR). The results demonstrated that the addition of fructose enhanced the deposition of phosphates forming thick and compact corrosion products, which inhibited the transmission of aggressive ions into the Mg substrate. As a result, both the anodic dissolution of Mg and negative difference effect (NDE) were suppressed. Thus, the corrosion resistance of AZ31 Mg alloy in SBF was significantly improved.

Recycled aggregate concrete (RAC) made with recycled concrete aggregates (RCA) is different from conventional concrete cast with natural aggregates due to the adhered cement mortar on RCAs to the former. Hence, the properties of concrete especially durability are expected to be affected when the RCAs are incorporated in the concrete mix. In this paper, two surface pretreatment methods were investigated to enhance the properties of RCAs and the durability performance of mixes was studied. The RCAs were coated by silica fume slurry manually and in the desiccator, namely RACCM and RACCD methods, respectively. The replacement level of coarse RCAs was considered at 100% in the mixes. Furthermore, three effective water-to-cement ratios (0.30, 0.35, and 0.40) were used. Tests were undertaken to establish the compressive strength, ultrasonic pulse velocity (UPV), electrical resistivity (ER), and chloride ion penetration resistance of each mix. Results indicated that compressive strength declined with the incorporation of RCAs and both pretreatment methods obviously enhanced the ER and chloride ion penetration resistance, which was significantly governed by silica fume slurry. More interestingly, test results indicated that the surface treatment methods were effective in reducing total charge passed. The RACCM method showed relatively more efficient results than RACCD.

Finding a suitable method for estimating soil and crop specific potassium (K) bioavailability under variable range of soil fertility has been a mighty challenge. To undermine this, a field experiment was conducted under varying levels of fertilizer application on pre-established fertility gradient strips in the Indo-Gangetic plains of West Bengal, India for predicting crop response and to assess the K availability in winter growing broccoli by employing six acclaimed chemical extractants viz. ammonium bicarbonate-diethylenetriaminepentaacetic acid (AB-DTPA), calcium chloride (CaCl2), Kelowna, Mehlich-III, ammonium acetate (NH4OAc), and sodium tetraphenylborate (NaTPB4). The availability study of K followed the pattern as, CaCl2 < AB-DTPA < Kelowna < NH4OAc < Mehlich-III < sodium tetraphenylborate (NaTPB4). A higher extractability of K was envisaged under the conjoint application of higher doses of K fertilizers along with the organics. Among the extractants, NaTPB4 showed the highest correlation sum (3.98) and also yielded a significant relationship with plant tissue K concentration (0.858) and uptake (0.715). The NaTPB4, Mehlich-III, and NH4OAc extractants were found to be significantly related to most of plant indices. The Euclidean distance based cluster analysis and linear regression study further proved the relatively higher efficiency of NaTPB4 extractant followed by Mehlich-III and NH4OAc to estimate plant K response in broccoli under the Gangetic alluvial soils of West Bengal, India.

The precise regulation of the deep eutectic solvents (DESs) system has an important influence on its structure, performance and application. In this work, choline chloride (ChCl) and three kinds of butanediols are used as hydrogen bond acceptors and donors, respectively. The research focuses on the influence of two hydroxyl positions in butanediols on the structure and properties of DES systems with various characterization techniques. The results show that the DES system composed of 1, 2-butanediol and ChCl (the distance of two hydroxyl group is closest) possesses the largest conductivity (1.26 mS cm(-1)) and the lowest viscosity (56.99 cP). Moreover, using ChCl and 1, 2-butanediol as the electrolyte, the corresponding voltage of activated carbon (AC) based supercapacitor can reach 2 V, the specific capacitance can reach 116 F g(-1) and the highest energy density is 16.14 Wh kg(-1). More importantly, this work uses the DFT model to design and verify the DES systems in detail, and then explain the mechanism of the influence of the hydroxyl position on the structure and electrochemical performance of the DES system from a theoretical perspective. Obviously, the DES systems having difference structures and DFT calculation proposed in this article provide a significant way and reference for in-depth understanding of DES electrolytes and applications.

Hydroxymethylfurfural (HMF) is one of the important renewable platform compounds that can be obtained from biomass feedstocks through glucose conversion catalyzed by Bronsted and Lewis acids. However, it is challenging to enhance the HMF yield due to side reactions. In this study, a systematic approach combining theory and experiment was performed to investigate the influence of Lewis acids and organic solvents on the HMF yield. For the Lewis acid effect, a relationship between chemical hardness and experimental HMF yields was found in the rate-limiting step of glucose-to-fructose isomerization for six metal chlorides; HMF production was promoted when the metal chloride and a substrate had a similar chemical hardness. To study the organic solvent effect, a multivariate model was developed based on the insights gained from the mechanistic study of fructose dehydration, to predict HMF yields in a given water-organic cosolvent system. It showed a reliable accuracy in evaluating HMF yields with a mean absolute error (MAE) of 3.0% with respect to experimental HMF yields for 13 solvents, and also predicted HMF yields with a MAE of 10.7% for four new solvents. Chemical interpretation of the model revealed that it is desirable to use a solvent capable of stabilizing the carbocation intermediates with low proton transfer activity and high hydrogen bond basicity, to maximize the HMF yield. This multivariate model informs experimentalists about rational selection of solvents with very low computational costs needed to calculate only six variables for each solvent. It can be expanded to other catalytic systems such as heterogeneous Bronsted-Lewis bifunctional catalysts and enables optimization of reaction conditions to obtain other useful platform molecules through biomass conversion.
