AbstractAbstract
[en] Olive pomace, which is considered as one of the worst agro-industrial wastes in Mediterranean countries was tested for bioactive compounds production through the solid state fermentation of Kluyveromyces marxianus. Because they present potent biological activities, phenolic compounds from both unfermented and fermented pomace were extracted with simultaneous evaluation of their antioxidant and anticancer activities. Conditions for optimum total phenolic recovery with maximum antioxidant activity were optimized using methanol as the extracting solvent with a sample to solvent ratio of 1:10 at 50 °C for 2 hours. The in-vitro anticancer activity of both extracts was assessed against different human cancer cell lines. The results revealed that both extracts exerted anticancer effects close to the value of doxorubicin drug against liver HepG2 and breast MCF-7 cell lines, and moderate activity against prostate PC3 and colon HCT116 cell lines. Nevertheless, the fermented extract was more potent than the unfermented one. No effect against lung A549, cervix Hela cancer cell lines or normal HFB4 cells was observed for both extracts. A GC/MS analysis was carried out to determine the compounds responsible for antioxidant and anticancer activities. The results showed the presence of methyl palmitate, methyl oleate, and ethyl oleate in the methanolic extract of unfermented olive pomace, while that of the fermented one showed the production of carvacrol, thymol, eugenol, caryophyllene oxide and methyl isopalmitate.

El orujo de oliva considerado como uno de los peores residuos agroindustriales en los países mediterráneos fue ensayado para la producción de compuestos bioactivos mediante fermentación en estado sólido de Kluyveromyces marxianus. Se extrajeron los compuestos fenólicos de orujos fermentados y no fermentados ambos con potentes actividades biológicas y se evaluaron sus actividades antioxidantes y anticancerígenas. Se optimizaron las condiciones para la recuperación fenólica óptima con actividad antioxidante máxima, estas se lograron usando metanol como disolvente de extracción con una relación de muestra a disolvente de 1:10 a 50 °C durante 2 horas. La actividad anticancerígena in vitro de ambos extractos se evaluó frente a diferentes líneas celulares de cáncer humano. Los resultados revelaron que ambos extractos ejercen un efecto anticancerígeno cercano al valor del fármaco doxorrubicina contra líneas celulares hepáticas HepG2 y MCF-7 de mama, y actividad moderada contra líneas celulares de PC3 de próstata y HCT116 de colon, sin embargo, el extracto fermentado fue más potente que el no fermentado. No se observó ningún efecto contra las líneas celulares A549 de cáncer el pulmón, de cuello de útero o células HFB4 normales, para ambos extractos. El análisis GC/MS se llevó a cabo para determinar los compuestos responsables de las actividades antioxidantes y anticancerígenas. Los resultados mostraron la presencia de palmitato de metilo, oleato de metilo y oleato de etilo en el extracto metanólico de orujo de oliva no fermentado, mientras que el fermentado mostró la producción de carvacrol, timol, eugenol, óxido de cariofileno e isopalmitato de metiloOriginal Title

AbstractAbstract
[en] In this paper, we investigate the (2+1)-dimensional Chiral nonlinear Schrödinger equation (CNLSE) via two random sources. Namely, we solve this equation forced by multiplicative noise in Itô sense and the spatio-temporal coefficient or the wave transition follows beta random variable. We present some new stochastic solutions. These stochastic solutions are of great importance for investigation vital complex phenomena in optical fiber communication, computer industry, plasma physics, etc. We introduce the graphical simulations for some of the acquired solutions via the choice of suitable parameters through the MATLAB software for investigating the real significance of the CNLSE. Finally, our new motivation can be extended to further models arising in natural science. (author)

AbstractAbstract
[en] In this article, analytical and numerical solutions to the simplified modified Camassa–Holm (MCH) equation by using the Riccati–Bernoulli (RB) sub-ODE method and moving mesh method are obtained. Some new solutions are given. The discrtisation of the presented model is introduced in the form of finite difference operators. Some 3D graphs for the presented solution are plotted with the aid of the Matlab software for suitable values of parameters. We introduce the comparison between numerical and exact solutions.

AbstractAbstract
[en] In this article, we applied the unified solver method to extract stochastic solutions of a new stochastic extension of nonlinear Schrödinger equation. This solver gives the closed formula in explicit form. The acquired stochastic solutions may be applicable for explaining some phenomena in many fields of applied sciences. The presented results illustrate that the proposed solver is efficient and adequate. Moreover, the constraint conditions are utilised to verify the existence of solutions. Chi-square statistical distribution is chosen to represent the dispersion random input. In order to illustrate the dynamical behaviour of random solutions, the expectation value and their variance are depicted graphically using suitable parameters. (author)

AbstractAbstract
[en] The unstable nonlinear Schrödinger equation (UNLSE) characterises the time evolution of disturbances through unstable or marginally stable media. We study the stochastic UNLSE and stochastic modified UNLSE (mUNLSE). We apply the unified solver to provide some new stochastic solutions via Rayleigh distribution. The gained stochastic solutions play a crucial role in nonlinear sciences. Rayleigh distribution is used to depict the dispersion random input. In light of description of the behaviour of stochastic solutions, their mean and variance are illustrated. We show the influence of random parameters on the gained stochastic solutions. With the aid of Maple software, various profile pictures are introduced to exhibit the dynamical behaviour of the stochastic solutions. (author)

AbstractAbstract
[en] In this paper, we look at higher-order nonlinear Schrö dinger equation (HONLSE) through stochastic sense. This equation is examined in the presence of Brownian motion and noise term. Using the robust solver, we generate several new crucial stochastic solutions for the HONLSE. During fibre transmissions, the HONLSE coefficients, such as nonlinearity, dispersion and noise term, influenced the solitonic picture. The solitary properties of communication fibers were altered by higher-order features. To illustrate how these optical solutions behave physically, certain representations of the acquired solutions as super and shock-like shapes are introduced. The presented research can be extended to other nonlinear equations with comparable properties. (author)
