In this work, a novel structure of an all-optical biosensor based on glass resonance cavities with high detection accuracy and sensitivity in two-dimensional photon crystal is designed simulated. The free spectral range which the performs well about FSR = 630 nm. This sensor measures concentration glucose human urine. Analyses to determine urine for normal (0~15 mg/dL) despite concentrations 0.625, 1.25, 2.5, 5 10 g/dL wavelength 1.326404~1.326426 μm have been conducted. RIU 0.2 × 10−7....
Abstract In this study, magnetic spinel copper ferrite (CuFe 2 O 4 ) nanostructures were eco-friendly synthesized using Nasturtium officinale extract. Physicochemical properties of these determined by transmission electron microscopy, field emission scanning microscopy (FE-SEM), X-ray diffraction (XRD), vibrating sample magnetometry, and energy dispersive mapping analysis. XRD patterns conform to the CuFe formation. SEM results demonstrated ceramic with spherical surface morphologies. The...
This paper presents the first quantitative ethnobotanical study of flora in semi-arid region southwest part Algeria. The aim this survey El Bayadh situated Algeria was to identify main medicinal plants used by local inhabitants treat different diseases and collect all data on their therapeutic characteristics. One hundred informants ages were interviewed for (69 women 31 men). Both qualitative information collected through open semi-structured face-to-face interviews with people. Data...
Abstract In this work, novel Gd 2 O 3 /SrFe 12 19 @Schiff base chitosan (Gd/SrFe@SBCs) nanocomposite was prepared, and characterized using FT‐IR, XRD, DSC, VSM, FE‐SEM, X‐ray energy dispersive spectrum (EDS), map analyses. All results confirm that the nanocomposite/Schiff successfully prepared. EDS analyses predict all elements are well distributed to compound. VSM shows title compound has high saturation magnetic of 17.35 emu/g with coercivity 4,664 Oe. addition, Gd/SrFe@SBCs were used as...
Breast cancer is the most prevalent among females with different molecular subtypes. Corosolic acid a pentacyclic triterpenoid anti-cancer properties.The MTT assay was used to assess cytotoxic activity of corosolic on MDA-MB-231 and MCF7 cell lines. To determine apoptotic cells, flow cytometry technique utilized. The expression levels apoptosis-related genes proteins were quantified using quantitative real time-PCR (qRT-PCR) Western blotting methods. caspase enzymes measured by...
Abstract In this study, modified chitosan with epichlohydrin and bidentate Schiff base ligand (CEP) was successfully synthesized characterized using Fourier transform infrared spectroscopy (FT‐IR), differential scanning calorimetry (DSC), X‐ray powderdiffraction (XRD), electron microscopy (SEM). addition, its removal ability of Pb 2+ Cd ions studied the effect various parameters such as pH solution, sorbent dose, contact time on adsorption were investigated optimized. At optimal conditions...
Xylan-type polysaccharides were isolated from the leaves of Argania spinosa (L.) Skeels collected in Tindouf area (southwestern Algeria). Xylan fractions obtained by sequential alkaline extractions and purified on Sepharose CL-4B. The xylan structure was investigated enzymatic hydrolysis with an endo-β(1→4)-xylanase followed chromatography resulting fragments Biogel P2, characterization sugar analysis matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF MS )....
The pectin polysaccharides from leaves of Argania spinosa (L.) Skeels, collected Stidia area in the west coast northern Algeria, were investigated by using sequential extractions and resulting fractions analysed for monosaccharide composition chemical structure. Water-soluble pectic (ALS-WSP) chelating-soluble (ALS-CSP) obtained, de-esterified fractionated anion-exchange chromatography characterized sugar analysis combined with methylation (1)H (13)C NMR spectroscopy. data reveal presence...
The present study aimed to examine the composition of essential oil extracted from flowers Algerian Artemisia judaica L. (ssp. sahariensis) and its possible used as a natural cosmetic preservative. A. (AJEO) was by hydrodistillation determined gas chromatography (GS) GC coupled with mass spectrometry. Twenty-nine compounds, corresponding 93.2 % total AJEO were identified, piperitone dominant component (71.1 %). antioxidant activity estimated 2,2-diphenyl-1-picrylhydrazyl (DPPH) test reducing...
This study was performed to investigate the chemical composition of essential oil in leaves Eucalyptus globulus from Saïda region, southwest Algeria, as this has not been investigated date. We through gas chromatography coupled with mass spectrometry. The extraction by hydrodistillation provided a yield 2.64 %. A total 75 compounds were identified, among which dominant constituents p-cymene (20.24 %), spathulenol (14.10 %) and eucalyptol (11.30 %). Other notable identified extracted...
The objective of this study was to analyse the chemical composition and antibacterial activity essential oils derived from leaves A. spinosa (ASEO), found in Stidia region on western coast northern Algeria. Among 36 terpenic compounds identified, cubenol (31.02%) 1,10-di-epi-cubenol (22.50%) were most abundant, followed by camphor (8.22%), viridiflorol (7.10%), linalool (5.60%), eucalyptol (5.40%). To best knowledge authors, is first identify as major constituents spinosa-derived oil, with...
