In this study, heavy metals (Hg,Cd,Pb,Cu,Zn) and metallothionein (MT) biosynthesis were measured in blood of green sea turtles (Chelonia mydas) nesting on the northern coast of the Sea of Oman. Heavy metals concentrations in the sea water, the sediments, the blood samples ranged between 0.02-8.43 μg/l, 0.06-10.32 μg/l, and 0.16-36.78μg/g (ww), respectively.The highest concentration...
Clematis tientaiensis is an ornamental plant with beautiful flowers that belongs to the Ranunculaceae family. C. endemic Zhejiang Province in China. Five different colours of flower have been observed, and explore reason for this colour variation, transcriptome metabolome sequencing analyses were conducted study. The results indicate 32 metabolites participate anthocyanin biosynthesis, 24 diffe...
aflatoxins are secondary toxic metabolites produced by some aspergillus spp. particularly, aspergillus flavus and a. parasiticus that contaminate food and feed. the objective of this study was to evaluate the contamination of feedstuffs with aspergillus spp. and detect genes involved in the aflatoxin biosynthesis pathway of a. flavus and a. parasiticus isolates. a total of 110 cow feed samples ...
Handroanthus and Tabebuia are known for their ornamental medicinal value, which attributed to metabolites. However, the mechanisms underlying synthesis of these metabolites poorly understood. In this study, expression levels secondary mechanism flavonoid biosynthesis in bark leaves chrysantha (Jaq.) were examined using transcriptomic metabolomic techniques. Metabolic analysis identified several...
It has been shown that chronic exposure to cypermethrin (CPM), a pyrethroid pesticide, results in follicular atresia via pathologically affecting angiogenesis, disrupting endocrine potential and enhancing oxidative stress. This study was aimed to uncover the CPM-exposed energy dependent follicular cells apoptosis and to estimate protective effect of vitamin E (VitE) as a potent antioxidant. Thi...
Background and Objective: Present study aimed to investigate response of metallothionein (MT) in oyster Crassostrea sp. to the experimental concentrations of Hg and Cd in order to assess the possibility of MT usage as a biomarker of Hg and Cd contamination in this mollusk. Materials and Methods: Oysters were collected from docks of Imam Khomeini Port. After seven days acclimation period in labo...
3 beta-Hydroxy-Delta-5-steroid dehydrogenase is an important key anzyme of steroid hormone biosynthesis, which is involved in catalyzing the conversion of pregnenolone to progesterone in the biosynthesis of steroid sex hormones. This complex enzyme is the second enzyme in the steroid hormone biosynthesis pathway and it is identified as an autoantigenic target. In this study, a simple ...
Background and purpose: Development of biocompatible and nontoxic methods for synthesis of nanoparticles is important in bio-nanotechnology. This study aimed at biosynthesis of titanium dioxide nanoparticles (TiO2 NPs) using leaf of the native mangrove (Avicennia marina) and investigating its antibacterial activity. Materials and methods: Effect of four different solutions composed of dry extr...
