1.Enhanced coagulation-photocatalytic treatment of Acid red 73 dye and real textile wastewater using UVA/synthesized MgO nanoparticles.
Jorfi S1, Barzegar G2, Ahmadi M3, Darvishi Cheshmeh Soltani R4, Alah Jafarzadeh Haghighifard N5, Takdastan A6, Saeedi R7, Abtahi M8. J Environ Manage. 2016 Apr 14;177:111-118. doi: 10.1016/j.jenvman.2016.04.005. [Epub ahead of print]
Sequencing coagulation - photocatalytic degradation using UVA/MgO nanoparticles process was investigated for Acid red 73dye removal and then treatment of a real textile wastewater. Effective operational parameters including pH and coagulant and photocatalyst dosage were studied in synthetic wastewater and then the process was applied for real wastewater. Both coagulation and photocatalytic processes were pH dependent. At coagulant dosage of 200 mg/L and initial pH of 6, the dye concentration decreased from 200 to 31 mg/L. Complete removal of AR73 was observed with MgO nanoparticles of 0.8 g/L, initial pH of 5 and reaction time of 60 min. Langmuir-Hinshelwood model was well fitted with removal results (R2: 0.939-0.988 for different initial dye concentration). In the case of real textile wastewater, the sequence coagulation-UVA/MgO nanoparticles photocatalytic degradation yielded considerable total COD and TOC removal 98.3% and 86.9%respectively, after 300 min.
2.Crosstalk between liver antioxidant and the endocannabinoid systems after chronic administration of the FAAH inhibitor, URB597, to hypertensive rats.
Biernacki M1, Łuczaj W1, Gęgotek A1, Toczek M2, Bielawska K1, Skrzydlewska E3. Toxicol Appl Pharmacol. 2016 Apr 13. pii: S0041-008X(16)30076-X. doi: 10.1016/j.taap.2016.04.006. [Epub ahead of print]
Hypertension is accompanied by perturbations to the endocannabinoid and antioxidant systems. Thus, potential pharmacological treatments for hypertension should be examined as modulators of these two metabolic systems. The aim of this study was to evaluate the effects of chronic administration of the fatty acid amide hydrolase (FAAH) inhibitor [3-(3-carbamoylphenyl)phenyl]N-cyclohexylcarbamate (URB597) on the endocannabinoid system and on the redox balance in the livers of DOCA-salt hypertensive rats. Hypertension caused an increase in the levels of endocannabinoids [anandamide (AEA), 2-arachidonoyl-glycerol (2-AG) and N-arachidonoyl-dopamine (NADA)] and CB1 receptor and the activities of FAAH and monoacylglycerol lipase (MAGL). These effects were accompanied by an increase in the level of reactive oxygen species (ROS), a decrease in antioxidant activity/level, enhanced expression of transcription factor Nrf2 and changes to Nrf2 activators and inhibitors.
3.Antihyperlipidemic and Antioxidant Activities of Edible Tunisian Ficus carica L. Fruits in High Fat Diet-Induced Hyperlipidemic Rats.
Belguith-Hadriche O1,2, Ammar S3,4, Contreras MD4, Turki M5, Segura-Carretero A4, El Feki A6, Makni-Ayedi F5, Bouaziz M7. Plant Foods Hum Nutr. 2016 Apr 16. [Epub ahead of print]
The phenolic constituents of the aqueous-ethanolic extract of Tunisian Ficus carica (F. carica) fruit (FE) and its antihyperlipidemic and antioxidant activities in high-fat diet-induced hyperlipidemic rats (HFD) were evaluated. The obtained results demonstrated that the FE improved the lipid profile by decreasing the total cholesterol, triglyceride, low-density lipoprotein cholesterol and increasing high-density lipoprotein cholesterol levels. It also reduced the content of thiobarbituric acid-reactive substances and increased the antioxidant enzymes in liver, heart and kidney in HFD-fed rats. These antihyperlipidemic effects and in vivo antioxidative effects correlated with the in vitro phenolic content scavenging ability. Thus, the major phenolic compounds were identified using reversed-phase ultra-high-performance liquid chromatography (RP-UHPLC) coupled with two detection systems: diode-array detection (DAD) and quadrupole time-of-flight (QTOF) mass spectrometry (MS).
4.Dengue outbreak in Swat and Mansehra, Pakistan 2013: An epidemiological and diagnostic perspective.
Suleman M1, Faryal R2, Aamir UB3, Alam MM3, Nisar N3, Sharif S3, Shaukat S3, Khurshid A3, Angez M3, Umair M3, Mujtaba G3, Sufian MM3, Arshad Y3, Rehman L3, Zaidi SS4. Asian Pac J Trop Med. 2016 Apr;9(4):380-4. doi: 10.1016/j.apjtm.2016.03.010. Epub 2016 Mar 9.
OBJECTIVE: To high light some epidemiological, clinical and diagnostic features of dengue fever during an outbreak and the role of different diagnostic techniques to achieve the highest level of accuracy in results.
