Aerial parts of Citrus aurantium L. were subjected to headspace (HS) and hydro-distillation (HD) techniques after drying, and then headspace volatiles and the essential oil were analyzed by GC/MS. Results of GC/MS analysis led to identification seventeen (99.8%) and sixteen (99.9%) constituents in samples extracted by HS methods in leaf and flower, respectively. (E)-β-ocimene (2.5%), Linalool (...
The emergence of antibiotic-resistant Salmonella is of concern to food processors. The objective of this research was to identify antimicrobial activities of cinnamaldehyde and carvacrol against antibiotic-resistant Salmonella enterica in phosphate-buffered saline (PBS) and on celery and oysters. Twenty-three isolates were screened for resistance to seven antibiotics. Two resistant and two susc...
Background: Multiple sclerosis (MS) is the most prevalent central nervous system demyelinating disease. There are known risk factors for MS. However, there is uncertainty in its protective factors. Few studies have demonstrated that some chronic infections may have protective effects on this disease. We carried this study to investigate the relation between Helicobacter pylori (HP) infe...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
objective: multiple sclerosis (ms) is one of the leading neurodegenerative causes of physical disability world-wide. genetic aberrations of autoimmunity pathway components have been demonstrated to significantly influence ms development. cluster of differentiation 58 (cd58) is pertained to a group of genes which had been assayed in several recent association studies. given the significance of c...
Background and objectives: Cichorium intybus products are one of the best sellers in market Because of their effect on treatment of infection, poisoning, diabetes and allergy. This is the first study about Cichorium intybus market samplephytochemical compounds and the aim of this study was to define a method to recognize the original products. Methods:...
The essential oil from the aerial parts of Iranian and British Thymus vulgaris L. were obtained by hydro distillation and analyzed by gas chromatography (GC) and gas chromatographymass spectrometry (GC-MS). Forty two components were identified in the Iranian Th. vulgaris essential oil that represented 99.06% of the oils. The major components were thymol (60.54%), γTerpinene (9.47%), p-cymene (8...
recent studies in scientific education as well as foreign and second language instruction suggest that thinking has rarely been an integral part of education and training in classroom. some scholars decried the lack of emphasis on thinking in the institutes and schools. they noted that memorization and drills were rewarded,while inquiry, reflection, and consideration of alternatives were frowne...
Clostridium difficile is a nosocomial pathogen that causes a serious toxin-mediated enteric disease in humans. Reducing C. difficile toxin production could significantly minimize its pathogenicity and improve disease outcomes in humans. This study investigated the efficacy of two, food-grade, plant-derived compounds, namely trans-cinnamaldehyde (TC) and carvacrol (CR) in reducing C. difficile t...
We conducted field trials to compare the relative repellent activity of two natural product compounds (nootkatone and carvacrol) with commercially available plant-derived (EcoSMART organic insect repellent) and permethrin-based (Repel Permanone) repellents against adult Ixodes scapularis Say and Amblyomma americanum (L.) (Acari: Ixodidae) by using treated coveralls. One day after treatment, noo...
