In this investigation, by the time series data of exchange rate and petrochemical industry stock index in the Tehran Stock Market from March 2009 to April 2019, a new Hybrid Model (resulting from the use of Exponential Generalized Autoregressive Conditional Heteroscedasticity, EGARCH, Model and Markov Switching Regime Model) is used. The results of study, in addition to confirming the idea of ...
Background and Objectives: Essential and minor components of the goat milk are unique ingredients in production of various food products. In this study, characteristics of Nodooshan goat milk were investigated and volatile compounds were identified in traditional Nodooshan goat cheese during ripening. Materials & Methods: Physicochemical tests were carried out on raw milk, fresh cheese and ri...
Microwave-assisted extraction of volatile oils (MAE) potentially offers a more efficient and bio-sustainable method than conventional extraction by Clevenger apparatus (CE). This study aimed to optimise the MAE of the volatile oil from Pterodon emarginatus fruits and characterise the volatile compounds. A 2³ full-factorial central composite design and response surface methodology were used to e...
Selective ion flow tube mass spectrometry (SIFT-MS) is a direct mass spectrometric technique that allows qualitative and quantitative analysis of a large number of volatile organic compounds. Because of its speed and ease of use, this nondestructive technique could be considered as a practical tool for quality control. This research focuses on the possibilities of direct headspace sampling by S...
Rosemary is commonly used as a spice and a flavoring agent in food processing. Although the antioxidative properties of its extracts have been investigated, there have been few reports on the volatile components of rosemary. We designed a novel antioxidative system which can generate the volatile constituents in the gaseous phase from a rosemary extract and evaluated the gaseous antioxidative a...
AKI is a major clinical problem with extremely high mortality and morbidity. Kidney hypoxia or ischemia-reperfusion injury inevitably occurs during surgery involving renal or aortic vascular occlusion and is one of the leading causes of perioperative AKI. Despite the growing incidence and tremendous clinical and financial burden of AKI, there is currently no effective therapy for this condition...
OBJECTIVE To evaluate the effects of Rhizoma kaempferiae volatile oil on tumor growth and cell cycle of MKN-45 human gastric cancer cells orthotopically transplanted in nude mice. METHODS One hundred and five nude mice orthotopically transplanted with MKN-45 human gastric cancer cells were randomly divided into seven groups: untreated group, normal saline-treated group, dissolvant-treated gro...
Numerous studies have revealed the extent of genetic and phenotypic variation between both species and cultivars of tomato. Using a series of tomato lines resulting from crosses between a cherry tomato and three independent large fruit cultivar (Levovil, VilB, and VilD), extensive profiling of both central primary metabolism and volatile organic components of the fruit was performed. In this st...
Plant volatiles mediate numerous interactions between plants and insects, yet few studies have examined variation in volatile production within plant populations or the genetic and environmental causes of this variation. Here we document the effects of inbreeding and maternal family on volatile production by horsenettle Solanum carolinense L. (Solanaceae). We collected volatiles from ramets (cl...
