In vitro cytocompatibility evaluation of nanostarch reinforced polyaniline-polyvinyl alcohol conductive bionanocomposites for skin tissue engineering application
Springer Science and Business Media LLC - Tập 9 - Trang 252-259 - 2023
D. Switha, S. Khaleel Basha, V. Sugantha Kumari
In this study, we aimed to fabricate nanostarch (NS) reinforced polyaniline/polyvinyl alcohol (PANI-PVA) bionanocomposite of polyaniline-polyvinyl alcohol-nanostarch for skin tissue engineering application. The microstructure of the bionanocomposite was analyzed using TEM and the particle size ranged from 35 to 37 nm. The swelling degree was increased with the increase in the concentration of nano...... hiện toàn bộ
An eco-friendly ultrasound-assisted deep eutectic solvent-based liquid–phase microextraction method for enrichment and quantification of nickel in environmental samples
Springer Science and Business Media LLC - Tập 8 - Trang 57-68 - 2022
Ahmed M. Hameed
An eco-friendly and easy ultrasound-assisted liquid phase microextraction approach using deep eutectic solvent (UA-DES-LPME) was established to preconcentrate and separate trace amount of nickel (Ni(II)) in various environmental samples before flame atomic absorption spectrometric estimation. In this method, Ni(II) was complexed with 2-(benzothiazolyl azo) orcinol reagent. The impacts various para...... hiện toàn bộ
Anti-aging trait of whey protein against brain damage of senile rats
Springer Science and Business Media LLC - Tập 8 - Trang 8-20 - 2022
Mohamed E. El-Beeh, Ashraf A. El-Badawi, Ali H. Amin, Sameer H. Qari, Mohamed Fawzy Ramadan, Wessam M. Filfilan, Hassan I. H. El-Sayyad
Aging mammalian results in impaired bio-functions and neurological disorders. The current study investigated whether whey protein (WP) syrup supplementation may improve age-related changes in diseased brain indicators like tau protein, β-amyloid and α-amylase. The study was carried out in conjunction with immunohistochemistry, histology, and flow cytometry of apoptosis. At the ages of 8 and 30 mon...... hiện toàn bộ
Clay-based materials for enhanced water treatment: adsorption mechanisms, challenges, and future directions
Springer Science and Business Media LLC - - 2023
Shahab Khan, Sanila Ajmal, Tanveer Hussain, Mudassir Ur Rahman
Water treatment is of paramount importance to ensure the availability of clean and safe drinking water. In recent years, clay-based materials have gained significant attention as promising adsorbents for water treatment applications. This review provides a comprehensive analysis of different clay types and their surface adsorption properties for water treatment. This review begins by introducing t...... hiện toàn bộ
Synthesis and characterization of liquid crystal methyl methacrylic monomers
Springer Science and Business Media LLC - Tập 10 Số 1 - Trang 129-135 - 2024
Olusegun Amos, Georg H. Mehl, Rami Adel Pashameah
AbstractThree liquid crystalline monomers were systematically designed, synthesised and characterised. Methyl methacrylic unit was linked to the mesogenic compound, 4′-Undecycloxybiphenyl-4-yl 4-octyloxy-2-(pent-4-en-1-yloxy) benzoate, (Me), using disiloxane, ester and siloxane units respectively. In the first compound, 4′-(undecyloxy)-[1,1′-...... hiện toàn bộ
Application of geothermometric and hydrochemical methods to the investigation of thermal water of sources in the Northeastern of Algeria case of Setif city
Springer Science and Business Media LLC - Tập 8 - Trang 69-78 - 2022
Djemmal Samir, Chamekh Khemissi
Thermal water in northeastern Algeria (Setif) is a promising, sustainable resource of energy. To date, thermal water has not been used as a source of renewable energy in Algeria as no clear strategy has yet been developed for its use. In this study, eight samples of thermal water springs distributed within the area of Setif city were assessed, and their physical and chemical parameters (such as te...... hiện toàn bộ

AbstractThe fully relativistic multiconfiguration Dirac–Hartree–Fock (MCDHF) approach was used to calculate the excitation energies and lifetimes for the lowest 272 levels that belonging to the $$2{s}^{2}2{p}^{3}$$ 2 s 2 2 p 3 , $$2s2{p}^{4}$$ 2 s 2 p 4 , $$2{p}^{5}$$ 2 p 5 , $$2{s}^{2}2{p}^{2}3l$$ 2 s 2 2 p 2 3 l , $$2s2{p}^{3}3l$$ 2 s 2 p 3 3 l , and $$2{p}^{4}3l$$ hiện toàn bộ
Up-to-date studies regarding the determination of sertraline by different analytical methods
Springer Science and Business Media LLC - - Trang 1-16 - 2024
Hussain Alessa, Nasser Algethami
Sertraline (SER), aka Zoloft, is one of modern antidepressant, it belongs to the selective serotonin reuptake inhibitor class, which functions to raise serotonin levels in the nervous system. SER has both mood-boosting and depressive effects but has bad influence on the gastrointestinal system. The monitor of SER and its major metabolites, desmethyl-SER (DSER) provides useful information that may ...... hiện toàn bộ

AbstractCancer and inflammation are important challenges and leading causes of death worldwide. Development of nanomaterial based therapeutic compounds obtained from natural products is thought to be a pillar in drug discovery. The present research describes the cytotoxicity, anti-inflammatory and antioxidant activities of cerium oxide (CeO2) a...... hiện toàn bộ
Certain results associated with mixed integral equations and their comparison via numerical methods
Springer Science and Business Media LLC - Tập 9 Số 1 - Trang 57-66 - 2023
Sharifah E. Alhazmi
AbstractIn this article, we consider existence and unique of solutions of linear mixed integral equations of third, second and first kinds. Then, we use the collection method to discuss numerical solutions by employing Chebyshev and Legendre polynomials. To support our results, we use Mable 18 to compute errors in all existing cases.
