Study of carcinogenic activity of carnosic acid and rosmarinic acid in cancer cell line of Hep- G2

Study of carcinogenic activity of carnosic acid and rosmarinic acid in cancer cell line of Hep- G2

In this experimental study, Hep -G2 cells were cultured in DMEM supplemented containing bovine fetal serum and antibiotics. Cells with double dilution were then cultured from 0 to 00 mu;M for 22 h and viability of cells was determined by MTT method. In order to evaluate activity of caspase3 and 9 enzymes after 22 hours of incubation of the cells with treated materials, cells were centrifuged and cell lysis solution was added. This mixture was centrifuged and then an appropriate substrate was ...

Acid rain and environmental problems

Acid rain and environmental problems

Acid rain is an outcome of air pollution which was first discovered in 1581. Acid rain formation is due to the atmospheric discharge of sulfur and nitrogen oxides which are mainly the outcome of burning the fossil fuels. Acid rain can cause environmental disruptions like; damaging the forests, lakes, groundwater, and soils. The damage caused by acid rain depends on the level of acid deposition and the natural sensitivity of soils and water bodies. There are set of solutions suggested which some ...

Removal of acid red 151 dye from aqueous solution using palm shell by adsorption: Isotherm Adsorption studies

Removal of acid red 151 dye from aqueous solution using palm shell by adsorption: Isotherm Adsorption studies

The objective of this research is removal of Acid Red 151(A.R.151) from aqueous solutionusing palm shell as low-cost adsorbent. The operating parameters such as pH solution, doseof adsorbent, initial dye concentration were investigated. Results showed that pH: 3, dose ofadsorbent: 2g/L and initial dye concentration: 20mg/L were the most suitable. In this study,the best fit of the adsorption isotherm data was obtained using the Langmuir model and showfavorable adsorption of A.R.151 dye with ...

The pH of the reaction mixture affects bio-production of lactic acid by loofa immobilized Rhizopus oryzae PTCC 5263

The pH of the reaction mixture affects bio-production of lactic acid by loofa immobilized Rhizopus oryzae PTCC 5263

Lactic acid production by Rhizopus oryzae PTCC 5263 was evaluated in the present study and the strain rsquo;s ability in production of this organic acid was carried out at various pH ranges of the culture media. Lactic acid production was optimized upon the fermentation being controlled at pH 4.5 by adding calcium carbonate slurry and maximum lactic acid concentration was 41 g/l. Additionally, the production of lactic acid by loofa immobilized R. oryzae was compared with free cells and the ...

ACETIC ACID BY THE CHIYODA/UOP ACETICA™ PROCESS (PEP Process Module, 19 Aug 1999)

فایل شبیه سازی Aspen بر اساس مجموعه SRI به همراه فایل pdf شرح فرآِیند

This Aspen Plus model simulates the production of acetic acid by low pressure methanol carbonylation in the presence of a heterogeneous rhodium (Rh) catalyst and the promoter methyl iodide. It is intended to resemble the Chiyoda/UOP Acetica™ process, a novel heterogeneous methanol process for the production of acetic acid. This technology is based on a heterogeneous Rh catalyst in which the active Rh complex is chemically immobilized on a polyvinylpyridine resin. In the Aspen Plus model, the plant (base case) is designed to produce 800 million lb/yr (363,000 t/yr) of acetic acid from methanol carbonylation. The process consists of both the carbonylation and purification sections. Results from the Aspen Plus simulation shows that the purity of acetic acid obtained is 98.4%. Vent gas (4,304 lb/hr) from two absorbers and heavy by-products (1,150 lb/hr) from the bottom of the heavy-ends stripper are sent to incinerator. The process also generates approximately 65,000 lb/hr of low-pressure (150 psig) steam that supplies a significant portion of the plant energy requirements.
