This paper reports the influence of sucrose on the preservation of CO2 hydrate crystal samples. The particle diameter of hydrate samples were 1.0 and 5.6-8.0 mm. Mass fraction of sucrose in the sample was 0.16. The samples were stored at the aerated condition under atmospheric pressure and at the temperature of 253 or 258 K. The results indicated that the mass fractions of CO2 hydrate in the sa...

Background. UVA irradiation is one of the most ubiquitous and penetrating environmental stress factor to human skin and it is crucially involved in various forms of skin damages including the photoaging and development of cancer. Mentioned skin damages are connected mainly with imbalance in redox status and consequently with cellular metabolic disturbances including changes in phospholipid medi...

We performed a sequence of tests on a partially water-saturated sand sample contained in an x-raytransparent aluminum pressure vessel that is conducive to x-ray computed tomography (CT) observation. These tests were performed to gather data for estimation of thermal properties of the sand/water/gas system and the sand/hydrate/water/gas systems, as well as data to evaluate the kinetic nature of ...

We have attempted to make the gas hydrate crystal in vegetable in order to extend the shelf life of fresh vegetable as preservation technique instead of freezing. As a result, it was confirmed that gas hydrate can be formed in onion tissue at 5 o C by pressurizing between 0.4 and 0.8 MPa Xe pressure. However, the detail conditions regarding to gas hydrate formation in vegetable tissue and their...

BACKGROUND Cisplatin (CP) is commonly used in the treatment of different types of cancer but nephrotoxicity has been a major limiting factor. Therefore, the present study aimed to study the possible protective effect of rutin against nephrotoxicity induced by cisplatin in rats. METHODS Forty male Wistar albino rats were randomly divided into 4 groups. Rats of group 1 control group intraperito...

OBJECTIVES Rutin, a polyphenolic flavonoid, was reported to have beneficial effect on drug induced nephropathy. The present study aimed to introduce 5/6 nephrectomized rat model to further evaluate its renal protective effect. METHODS Adult Wistar rats were induced to develop chronic renal failure through 5/6 nephrectomy (5/6 Nx). After that, animals were treated orally with saline, rutin at ...

[1] We developed a multicomponent, multiphase, fluid and heat flow model to describe hydrate formation in marine sediments; the oneand two-dimensional model accounts for the dynamic effects of hydrate formation on salinity, temperature, pressure, and hydraulic properties. Free gas supplied from depth forms hydrate, depletes water, and elevates salinity until pore water is too saline for further...

Clathrate hydrates are crystalline compounds composed of hydrogen-bonded water molecules that form polyhedral cavities and trap small guest molecules such as methane, carbon dioxide, cyclopentane (CP), and tetrahydrofuran (THF). Understanding the formation and dissociation of clathrate hydrates is of significant importance to addressing some global challenges such as greenhouse gas mitigation a...

The present study aims to investigate whether rutin and hesperidin could protect against acute doxorubicin (DXR)-induced testicular toxicity. Doxorubicin (DXR)– administered rats (25 mg/ kg; three times interaperitoneally/week for two weeks) were pretreated with rutin and/or hesperidin, (50 mg/ kg body weight) three times per week for three weeks and DXR 25mg/kg b.wt three times per week (at th...
