In this study, the effect of plant growth regulators (BA and NAA), ripe bananas in combination with potato, humic acid, and silver nanoparticles (AgNPs) were investigated to find a suitable condition for in vitro plant regeneration from R. imschootiana protocorm-like body (PLB). The results showed that after 45 days of culture, MS medium supplemented with 100 g ripe banana/liter and 100 g potato/liter was suitable for regenerating shoots from the protocorm-like body (PLB) (17.56 shoots/PLBs and 100.00% of shoot-regenerating PLBs).

In previous study, we found that the content of medium-chain fatty acid Caprylic Acid (FFA C8:0) may be an important risk factor of obesity-induced prostate cancer (PCa). However, the relationship between FFA C8:0 and PCa has not been reported. In this study, we explored whether the FFA C8:0 can promotes the progression of PCa by up-regulating Krüppel-like factor 7 (KLF7).

This study aimed to evaluate the potential of exosomes from cancer cells to predict chemoresistance in pancreatic cancer (PC) and explore the molecular mechanisms through RNA-sequencing and mass spectrometry. We sought to understand the connection between the exosomal Medium-chain acyl-CoA dehydrogenase (ACADM) level and the reaction to gemcitabine in vivo and in patients with PC.

In the present investigation, GNS have been prepared by an aqueous anodic exfoliation of pencil graphite in an acidic medium at different dc voltages (5 Ve12 V). The GNS prepared at optimum voltage were mixed with polyaniline (PANI) polymer and drop casted on an indium tin oxide (ITO)/Polyethylene terephthalate (PET) substrate to study the I-V characteristics and to measure the band gap of composites.

The present work is a development simple, sensitive and selective spectrophotometric method for determination of amoxicillin in dosage forms. Based on the diazotization of aniline and sulfanilic acid with nitrite ion in acidic medium to colorless diazonium ion, which subsequently coupled with amoxicillin to form a colored azo dye in the alkaline medium.

This study investigated the effects of different PGRs on in vitro plant regeneration of Anthurium scherzerianum Schott and acclimatization in the ex vitro stage. Depending on the objective of each experiment, the in vitro shoots were induced from callus cultured on a modified Murashige and Skoog (MS) medium containing cytokinins and auxins.

A glassy carbon electrode, modified with gold nanoparticles/over-oxidized poly-eriochrome black T film, was fabricated for sensitive determination of As(III) by stripping voltammetry in an acidic medium. The electrode surface properties were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS).

The peak for UA appeared at about –0.15 V in this medium, which responded well to standard additions and high reproducibility was obtained. The validity of the proposed method was tested in serum samples by spiking known concentrations of UA to serum samples and high recovery was obtained. The interference effect of dopamine (DA) and ascorbic acid (AA) was eliminated simply by the addition of Fe(III), in a very fast and quantitative reaction.

On the basis of slope analysis, the compositions of the extracted species were formulated as Pr(NO3)3.2Cyanex 921 and Pr(NO3)3.Cyanex 923. The percentage of extraction of Pr(III) was found to decrease with increases in temperature. The standard enthalpy and entropy changes were negative owing to the complexation with decrease in randomness without a compensatory disruption of the hydration sphere of the metal ion. Mineral acids like hydrochloric acid (0.008 M) and sulfuric acid (0.03/0.02 M) were effective for the stripping of Pr(III) from the loaded organic phase with 0.
