Abstract The anticancer activity of silver nanoparticles (AgNPs) is well known to be synthesized using green-synthesized methods, although its mechanism action not understood fully. Moringa oleifera leaves were used as reducing and stabilizing agents synthesize AgNPs. Green-synthesized AgNPs characterized ultraviolet-visible spectroscopy, dynamic light scattering, transmission electronic microscopy, scanning Fourier transform infrared, energy-dispersive X-ray spectroscopy analyses. then by...
Abstract Background Recently, a new generation of high-strength flowable dental composites has been introduced by manufacturers. The manufacturers claim that these materials have enhanced mechanical and physical properties are suitable for use in wide range direct anterior posterior restorations, even high-stress bearing areas. Aim objective this study was to assess certain recently comparison conventional multipurpose composites. Methods Four types (Genial Universal FLO, Gaenial Injectable,...
The aim of the study reported here was to evaluate performance a self-adhesive flowable composite and two self-etching adhesive systems, when subjected cyclic loading, in preventing nanoleakage Class V restorations.Wedge-shape cavities were prepared (4×2×2 mm [length × width depth]) on buccal surfaces 90 sound human premolars. Cavities divided randomly into three groups (n=30) according used (Xeno(®) [self-etching system]) BOND-1(®) SF (solvent-free system) conjunction with Artiste(®) Nano...
To investigate the effect of two acidic agents on microhardness nanofilled and microhybrid resin composite materials.70 discs (10 mm diameter 2 thick) were prepared from composites (35 each type), (Z350XT) (Z250), 3M/ESPE. Ten (5 group) used as control (tested at 1 h before immersion). Each group was divided into 3 subgroups (n = 10) according to storage media: distilled water (control), box-type cola orange juice. subgroup further subdivided divisions 5) testing 24 7days after immersions....
Fungal plant pathogens cause huge losses in agricultural production by decreasing crop yield and quality. To reduce loss from fungal damage, various synthetic fungicides are applied indiscriminately practice. The majority of non-biodegradable, several critical human health risks associated with them. Green synthesis nanotechnology offers an effectual, cost-effective, ecofriendly, innocuous method for the green nanofungicides, excellent replacement chemical fungicides. Origanum majorana is...
Abstract Green synthesized nanoparticles from plant extracts are being used in various biomedical applications, particularly because of their bactericidal and cytotoxic activities. In this study, silver (AgNPs) were successfully the Rosmarinus officinalis aqueous leaf extract. Different spectroscopic microscopic analyses such as ultraviolet-visible (UV-vis) spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy, energy-dispersive X-ray performed to verify...
Background This study was designed to evaluate the efficacy of standard at-home bleaching agents in comparison new over-the-counter (OTC) products on human enamel regarding color change, stability, and surface roughness. Methodology A total 80 extracted adult maxillary central incisors were prepared arbitrarily divided into following four equal groups (N =20): group A: opalescence boost containing 15% carbamide peroxide (CP); B: crest whitening strips 6% hydrogen (HP); C: light-emitted diode...
Evidence suggests that metformin, an antidiabetic drug, possesses antitumor effects in breast cancer.Although metformin is known to induce metabolic reprogramming, a detailed description of the metabolites altered by cancer cells limited.In this study, we aimed investigate metformin's anti-tumor effect on cell lines and conduct untargeted analysis those post-metformin treatment.Metformin's viability MCF-7 MDA-MB-231 was done using CCK-8 kit, apoptosis assay conducted Annexin V staining.HPLC...
Objectives: The aim of the current study was to compare accuracy different restorative materials currently used in porcelain laminate veneers (PLV) fabrication, terms external and internal adaptation, evaluate longevity PLV seal response thermocycling, microleakage. Methods: 30 preparations were performed on maxillary central incisor be restored with restorations fabricated by milling ceramic blocks using a CAD/CAM system. Samples divided randomly into three groups (n=10) according material...
Continuous advancements in composite resin materials have revolutionized and expanded its clinical use, improving physical mechanical properties. Attaining retaining surface texture gloss are crucial for the long-term durability of material. This study investigated supra-nanospherical filler material compared with different immersed beverages. The evaluated their roughness subsequent adhesion bacteria.
In Saudi Arabia, limited studies have evaluated factors including epidemiologic, clinical, and laboratory findings that are associated with COVID-19 disease. The aim of this paper was to identify parameters used in King Abdulaziz University Hospital which show an association disease severity patient outcome the form mortality.Age, gender, medical history, were all retrospectively assessed concerning a total 111 patients at between July 2020 August 2020. Patients categorized into mild if they...
Objectives:The aim of the current study was to evaluate resin-dentin micro-tensile bond strength (μ-TBS) using 2 types universal adhesives with etch-and-rinse and self-etch approaches after 24 hours 6 months water storage. Materials Methods:A total 20 extracted non-carious human molars were used in this study.Teeth equally randomly divided into groups (N= 10 teeth) according type adhesive used; Group I; Adhese® Universal II; Single Bond Universal.Each group further subdivided equal subgroups...
Text Cylindrotheca closterium alga belongs to family Bacillariaceae, order Bacillariales, class Bacillariophyceae and phylum Bacillariophyta.In this study was isolated from Alexandria coastal region (Eastern Harbor) using two methods: dilution method streak spray plating technique.Isolated algal cells were cultured on Guillard F2 liquid medium.Morphological identification carried out by light microscope scanning electric microscope.Algal found be wrapped the raphe canal of valves, which is a...
Background: This study was designed to assess the efficacy of standard home bleaching in comparison new over-the-counter (OTC) products on human enamel terms color change, stability, and surface roughness. Methods: A total eighty extracted adult maxillary central incisors were prepared randomly divided into four groups ( N=20 ) Group (at-home ): opalescence boost contains 15% carbamide peroxide (CP), B: crest whitening strips contain 6% hydrogen (HP), C: light emitted diode (LED) tray with...
Objectives: To investigate the marginal seal of new dentin substitutes using environmental SEM and evaluate longevity after being subjected to thermal stresses. Methods: Four different substitute materials (SDR, DENTSPLY; Sonic Fill, Kerr; Filtek Bulk 3M ESPE; Fuji II LC, GC Corporation) were tested in this study. MOD cavities (4mm depth half intercuspal distance width) prepared on eighty human sound extracted premolars. Teeth divided randomly into four groups according material. Each group...
