Value-added compounds were obtained from pine wood bio-oil, converting it into a renewable source for several chemicals: acids (acetic acid), sugars (levoglucosan), furan derivatives (furfural) and phenolics (catechol, phenol, 4-propylguaiacol, vanillin). To achieve this, firstly comparison of direct pyrolysis at 500 °C versus two-staged (300 °C) was made. It determined that ensue in the obtain...

The genus Artemisia is estimated to comprise over 800 species with anti-cancer, anti-fungal, anti-oxidant and anti-inflammatory properties. Artemisia fragrans (A. fragrans), a species that belongs to genus Artemisia, is rich in monoterpenes and sesquiterpenes derivatives. Due to anti-inflammatory properties of monoterpenes and sesquiterpenes, we aimed to investigate the effect of A. fragrans es...

Rosmarinus officinalis is one of the most important medicinal and aromatic plants around the world. Essential oil as a weapon against biotic and abiotic stresses plays an important role in essential oil bearing plants. In this study the essential oil content and constituent of plants containing bacterium-gall on the shoots and crown was compared with non-contaminated plants. Essential ...

Background: With the onset of the first wave of COVID-19 in Iran and the general quarantine, children who had to stay at home found themselves in contact with drugs, alcohol, and disinfectants. We aimed to compare the prevalence rates of poisoning for children and adolescents hospitalized during the first wave of COVID-19 versus the previous year (2019; “pre-COVID-19”). Methods: This analytic,...

Enzyme immobilization can promote several advantages for their industrial application. In this work, a lipase from Hypocrea pseudokoningii was efficiently linked to four chemical supports: agarose activated with cyanogen bromide (CNBr), glyoxyl-agarose (GX), MANAE-agarose activated with glutaraldehyde (GA) and GA-crosslinked with glutaraldehyde. Results showed a more stable lipase with both the...

OBJECTIVES This study investigated the postprandial effect of components of the Mediterranean diet on endothelial function, which may be an atherogenic factor. BACKGROUND The Mediterranean diet, containing olive oil, pasta, fruits, vegetables, fish, and wine, is associated with an unexpectedly low rate of cardiovascular events. The Lyon Diet Heart Study found that a Mediterranean diet, which su...

In recent years, numerous research work has been conducted in order to find the most practical and cost-effective solution for corrosion issues oil gas industry. Several studies have revealed that fatty hydrazide derivatives are suitable inhibitor application said These compounds can also act as effective inhibitors acidic medium with inhibition efficiency greater than 95%. This review summariz...

Although these 'tal' bases' are mainly derivatives of pyridine and/or quinoline, other compounds of a pyrrole nature have been reported to occur, for instance Petrie (1905) recorded the presence of pyrrole compounds in the oil obtained from the torbanites of New South "Vales, and aecounts of the shale oil from Colorado giving the same reaction have been reported by McKee (1£125). The first syst...
