title: Chiral discrimination of amlodipine from pharmaceutical products using capillary electrophoresis

description: The present work describes the development of a capillary electrophoresis (CE) method for the chiral discrimination of amlodipine (AML) enantiomers using cyclodextrine (CD) derivatives as chiral selectors. A large number of native and derivatized, neutral and ionized CD derivatives were screened to find the optimal chiral selector; and carboximethyl-β-CD (CM-β-CD) was selected for the enantiomeric discrimination. A factorial analysis study was performed by orthogonal experimental design in which several factors were varied at the same time to optimize the separation method. The optimized method (25 mM phosphate buffer, pH = 9.0, 15 mM CM-β-CD, 15 ºC, + 25 kV, 30 mbar/1 second, detection wavelength 230 nm) was successfully applied for the baseline separation of AML enantiomers within 5 minutes. Successful validation and application of the proposed CE method suggest its routine use in enantioselective control of AML in pharmaceutical preparations.

title: Finasteride promotes worsening of the cardiac deleterious effects of nandrolone decanoate and protects against genotoxic and cytotoxic damage

description: Metabolism of anabolic androgenic steroids is important for its physiological effects. The aim was to investigate the effects of finasteride (a 5α-reductase inhibitor - 5αR) on cardiac and mutagenic effects promoted by ND. Male Wistar rats were separated into three groups: CONT, received the vehicles of ND and finasteride (Peanut oil+Saline); DECA group, received ND (20 mg.kg.week-1, i.m.), and DECAF received ND and finasteride (100 µg.kg-1, i.p.), for four weeks. After, hypertrophy, cytokines and Angiotensin Converting Enzyme (ACE) activity was determined in heart. Bone marrow was used for micronucleus evaluation. Treatment with ND promotes increase in cardiac hypertrophy, ACE activity and disbalance among pro- and anti-inflammatory cytokines, and combination with finasteride worsened those effects. Association with finasteride ameliorates the toxic effects of ND on bone marrow cells, as was observed by a normalization of the number of micronucleate polychromatic erythrocytes and the mitotic index. Our data demonstrates that deleterious effects promoted by ND are depend, at least in part, of its metabolization. Also, inhibition of 5αR by finasteride present variated effects dependent on organ studied. It can promote increase on cardiac damage and a reduction on mutagenic effects of ND, which demonstrated that dehydronandrolone has diverse role on ND effects..

title: Synergistic effect of microRNA and albumin-bound nanoparticles for inhibition of glioblastoma cancer cell proliferation

description: The functional significance of upregulation miR-34a in combination with albumin-bound paclitaxel nanoparticles in U251 glioblastoma cell line has been evaluated. The MTT assay determined that miR-34a and albumin-bound paclitaxel nanoparticles can reduce cell viability, but the combination of both factors has a stronger effect on cell viability. The application of qRT-PCR has demonstrated that the transduction of miR-34a could lead to exogenous upregulation of miR-34a level and downregulation of SURVIVIN. Moreover, treatment of U251 cells with miR-34a and nanoparticles together considerably inhibit SURVIVIN expression compared to miR-34a and nanoparticles alone. Flow cytometry showed that upon miR-34a overexpression cell cycle arrested in G1 phase, while treatment with nanoparticles increased the cell population in G2 phase. Upregulation of miR-34a along with treatment with nanoparticles elevated the number of cells arrested in G1/ G2 phases of the cell cycle. Expression of miR-34a with albumin-bound paclitaxel nanoparticles reduced cell viability, downregulated SURVIVIN and enhanced cell cycle arrest in G1/G2 phases. Thus, the upregulation of miR-34a with these nanoparticles are potential candidates therapeutic for glioblastoma cancer.

title: Protective effects of Urtica dioica L. seed extract on liver tissue injury and antioxidant capacity in irradiated rats

description: Radiotherapy is often used for the treatment of cancer. However, it causes some side effects in patients. This study aimed to determine the hepatoprotective effects of Urtica dioica L. seed-extract (UDSE) in radiation-induced liver injury. Thirty-two male rats were randomly divided into 4 groups (n=8): control(C) group: no action was taken; radiation (R) group: irradiation was administrated at 5Gy single-fraction, radiation with UDSE(R+UDSE) group: irradiation was administrated at 5 Gy single-fraction and animals were fed pellets with 30 mL UDSE/kg; UDSE group: animals were fed pellets with 30 mL UDSE/kg. All of the experiments were performed in all of the groups over 10 days. Malondialdehyde (MDA) and reduced-glutathione (GSH) levels and superoxide-dismutase (SOD), catalase (CAT), glutathione-peroxidase (GSH-Px), aspartate-transaminase (AST), and alanine-aminotransferase (ALT) activities were determined. Histopathological findings were also evaluated in liver tissues. SOD, CAT and GSH-Px activities and GSH levels in the serum and liver were significantly increased, while MDA levels decreased in the R+UDSE group compared with the R group (P&lt;0.05). Moreover, AST and ALT serum activities in the R+UDSE group were lower than those in the R group (P&lt;0.05). In addition, radiation induced degenerative/necrotic changes in the R group were significantly compensated in the R+UDSE group. The results showed that radiation increased oxidative stress and decreased antioxidant capacity, as well as degeneration in the liver. However, UDSE attenuated these degenerative changes.

title: Adequacy of glyphosate doses in the Merremia cissoides (Lam.) Hallier f. control as a function of light intensity in the growth environments

description: Shading interferes with the weed's biology, which can change their sensitivity to post-emergence herbicides. The objective was to evaluate the control of Merremia cissoides with glyphosate in full sunlight and shade conditions in two plant growth stages (30 and 73 days after sowing (DAS)). Shading promoted 50 and 40% reductions in glyphosate doses at 30 and 73 DAS, respectively. At 73 DAS, M. cissoides is 177.77 and 131.48% more tolerant to glyphosate than 30 DAS in shading and full sunlight, respectively. Due to the increase in glyphosate tolerance as the plant grows, the management of M. cissoides should be carried out until the stage of six fully expanded leaves. Increasing glyphosate doses reduced the quantum yield of photosystem II and electron transport rate (ETR) in both growth environments, with ETR data showing a high negative correlation with the control. The doses reductions promoted by shading and glyphosate application in the initial growth stage of M. cissoides reduces costs and the negative environmental impacts of this herbicide use.

title: Ion-pairing liquid chromatographic method determination of ketoconazole and stress degradation in pharmaceutical formulations with fluorescence detection

description: Ion-pairing liquid chromatographic method was validated for determination of ketoconazole in shampoo and cream samples as per ICH guidelines. The chromatographic conditions were carried out in the isocratic mode using a mixture of methanol and 8 mM sodium dodecyl sulfate (pH 5.5) in a ratio of 45:55 v/v %, as mobile phase. The flow rate was set at 1.0 mL min-1. Chromolith RP-18e (100×4.6 mm) was used as the analytical column with a fluorescence detection at an excitation wavelength of 260 nm and an emission wavelength of 375 nm. The average percentage recovery of shampoo A, shampoo B, shampoo C, cream A and cream B were 99.88, 97.06, 99.58, 96.77 and 97.26, respectively. The limit of detection was 0.12 mg L-1. The drug decomposition under acid degradation, base degradation and oxidative degradation were found to be in the range of 91.63-94.70% indicating that the drug is resistant towards acidic conditions. The drug decomposition under thermal condition and photolysis condition were found to be in the range of 69.05-87.15% and 47.31-66.83% respectively, indicating that the drug decomposition is more sensitive under photolysis conditions. This method is suitable for the quality control of ketoconazole in commercial shampoo and creams.
