Replacement of methane with carbon dioxide in hydrate has been proposed as a strategy for geologic sequestration of carbon dioxide (CO(2)) and/or production of methane (CH(4)) from natural hydrate deposits. This replacement strategy requires a better understanding of the thermodynamic characteristics of binary mixtures of CH(4) and CO(2) hydrate (CH(4)-CO(2) mixed hydrates), as well as thermoph...

Rutin has anti-inflammatory, antioxidant, anti-viral, anti-tumor and immune regulatory effects. However, the neuroprotective effects of rutin in spinal cord injury are unknown. The p38 mitogen activated protein kinase (p38 MAPK) pathway is the most important member of the MAPK family that controls inflammation. We assumed that the mechanism of rutin in the repair of spinal cord injury is associ...

Accumulation of intracellular sorbitol due to increased aldose reductase (ALR2 or AKR1B1) activity has been implicated in the development of various secondary complications of diabetes. Previously we have reported that some common dietary sources such as spices, fruits and vegetables have the potential to inhibit ALR2 under in vitro conditions and in animal models. In this study, we describe th...

conclusions it seems that the preventive effects of rutin against damages caused by ida can be attributed to its ability to reduce apoptosis, which may be mediated by underexpression of caspase3 and overexpression of bcl2 genes. also, it could increase the expression of dazl that may be important in spermatogenesis. methods in the current experimental study, balb/c mice were divided into 8 grou...

We present an experimental study on the formation and dissociation characteristics of carbon dioxide (CO2) gas hydrates using Raman spectroscopy. The CO2 hydrates were formed from sodium chloride/water solutions with salinities of 0-10 wt %, which were pressurized with liquid CO2 in a stirred vessel at 6 MPa and a subcooling of 9.5 K. The formation of the CO2 hydrate resulted in a hydrate gel w...

The study examined the comparative rutin contents and antioxidant potentials of the two closely related Moringa species: the Ethiopian (Moringa stenopetala) and Indian Moringa (M. oleifera). It is demonstrated that M. stenopetala leaves extract was a far superior (more than five-fold better) antioxidant than M. oleifera. Rutin was the principal constituent of M. stenopetala leaves while the com...

The electrochemical behavior of ascorbic acid and rutin using a poly(L-arginine)-graphene oxide modified glassy carbon electrode (PLA-GO/GCE) has been studied by cyclic voltammetry and chronoamperometry. The modified electrode succeeds in distinguishing the electrochemical responses of ascorbic acid and rutin in a mixture solution due to its high electron transfer rate and good catalytic abilit...

Rutin is available in some foods, fruits, and vegetables. It has various beneficial medical effects making it useful in the treatment of various diseases. Rutin is available in different oral dosage forms such as tablets or capsules, widely available in the market. Rutin and many herbal medicines lack quality control due to unavailability of analytical methods. In this study, we formulated ruti...

Growth rate of a hydrate layer at the guest/liquid-water interface is analyzed considering the conjugate process of the mass-transfer and hydrate crystal growth. Hydrate-layer growth rate data in the literature are often compiled according to the system subcooling (∆T ≡ Teq − Tex, where Teq is the equilibrium dissociation temperature of the hydrate and Tex is the system temperature), suggesting...

This study aimed to construct the hydrate three-phase equilibrium curves for two typical Iranian gas reservoir samples using a high-pressure visual cell. To do so, complete analysis of the reservoir fluids was obtained by different techniques of composition analysis i.e. gas chromatography (GC) and detailed hydrocarbon analysis (DHA). Using high-pressure visual cell the hydrate phase equili...
