Evaluation of the antibacterial and antifungal properties of oleuropein, olea Europea leaf extract, and thymus vulgaris oil.

Background: Although synthetic preservatives and antioxidants may have high antimicrobial and antioxidant activity, they are usually associated with adverse effects on human health. Currently, there is a growing interest in natural antimicrobial and antioxidant agents. This study aimed to evaluate the antimicrobial activity of two medicinal plant extracts and one active compound.

Evaluation of the effectiveness of natural extract as a substituent for synthetic preservatives and antioxidants in pharmaceutical preparations.

Background: Despite the fact that synthetic preservatives and antioxidants have strong antibacterial and antioxidant activity, they are frequently associated with negative health consequences. Currently, there is an increasing interest in pharmaceutical products that are excellent in quality and free of synthetic preservatives.

Methods: As a result, the purpose of this research is to assess the antibacterial and antioxidant activities of olive leaf extract, oleuropein, and thymol in various pharmaceutical products.

Assessment of antioxidant, antimicrobial, and anticancer activities of plant extract.

The most efficient and safe source of medications is the natural and traditional medications which are produced from plants and herbs. In this study, () was tested to explore its total phenolic and flavonoids contents. Antioxidant, antimicrobial, and anticancer activities were assessed as well.

Biosynthesized silver nanoparticle-coated electro-membrane extraction of perchlorate in different seafood samples.

In this work we developed a rapid and straightforward technique in which biosynthesized silver nanoparticles (Ag-NPs) were coated on a porous membrane utilizing electrical potential to extract perchlorate from seafood samples. The biosynthesized Ag-NPs were well characterized using UV-Vis. spectrophotometry, X-ray diffraction, and scanning electron microscopy.

Determination of N-nitrosamines by automated dispersive liquid-liquid microextraction integrated with gas chromatography and mass spectrometry.

An automated dispersive liquid-liquid microextraction integrated with gas chromatography and mass spectrometric procedure was developed for the determination of three N-nitrosamines (N-nitroso-di-n-propylamine, N-nitrosopiperidine, and N-nitroso di-n-butylamine) in water samples. Response surface methodology was employed to optimize relevant extraction parameters including extraction time, dispersive solvent volume, water sample pH, sodium chloride concentration, and agitation (stirring) speed. The optimal dispersive liquid-liquid microextraction conditions were 28 min of extraction time, 33 μL of methanol as dispersive solvent, 722 rotations per minute of agitation speed, 23% w/v sodium chloride concentration, and pH of 10.

Prevalence and types of articulation errors in Saudi Arabic-speaking children with repaired cleft lip and palate.

Objectives: The purpose of this study was to assess prevalence and types of consonant production errors and phonological processes in Saudi Arabic-speaking children with repaired cleft lip and palate, and to determine the relationship between frequency of errors on one hand and the type of the cleft. Possible relationship between age, gender and frequency of errors was also investigated.

Methods: Eighty Saudi children with repaired cleft lip and palate aged 6-15 years (mean 6.

Application of electro-enhanced solid-phase microextraction for determination of phthalate esters and bisphenol A in blood and seawater samples.

The electro-enhanced solid-phase microextraction (EE-SPME) method was developed for the determination of endocrine disruptor compounds such as phthalate esters and bisphenol A in human blood and seawater samples. After EE-SPME, samples were analyzed by gas chromatography-mass spectrometry (GC-MS). In this approach, commercial SPME fiber was used in direct-immersion mode with an applied potential to extract di-ethyl phthalate, di-butyl phthalate, benzyl butyl phthalate and bisphenol A.

Determination of phthalate esters in bottled water using dispersive liquid–liquid microextraction coupled with GC-MS.

Dispersive liquid-liquid microextraction method was developed for the determination of the amount of phthalate esters in bottled drinking water samples and dispersive liquid-liquid microextraction samples were analyzed by GC-MS. Various experimental conditions influencing the extraction were optimized. Under the optimized conditions, very good linearity was observed for all analytes in a range between 0.

Consonant profile of Arabic-speaking school-age children in Jordan.

The paper provides a detailed consonant profile of 100 Jordanian children at the onset of formal schooling. The data were elicited through a modified version of Amayreh's (1994) articulation test. The findings showed that all consonants of Jordanian Spoken Arabic were acquired.

Completion of the consonant inventory of Arabic.

This study is a follow-up of previous research on the acquisition of Arabic consonants in normally developing children between the ages of 2 and 6 years. The purpose of this study was to provide normative data on the acquisition of late consonants that had not been acquired by the age of 6;4 (years;months). Speech samples from 60 Arabic-speaking children between ages 6;6 and 8;4, in Amman, Jordan, were analyzed to determine the age at which 10 late consonants had been acquired and to determine the error patterns and sound changes used.
