Changes In Growth, Biochemical Constituents, And Antioxidant Potentials In Radish (Raphanus Sativus L.) Under Cobalt Stress, Kaliyamoorthy Jayakumar, Cheruth Abdul Jaleel, Packirisamy Vijayarengan
Turkish Journal of Biology
The effects of cobalt (Co) stress on seedling vigor, photosynthetic pigment content, biochemical constituents, mineral status, and the activity of antioxidant enzymes in Raphanus sativus L. were studied. The plants were raised in earthen pots containing soils amended with different concentrations of Co (50, 100, 150, 200, and 250 mg kg^{-1}). Growth parameters (root and shoot length, and total leaf area), photosynthetic pigments content (chlorophyll a, chlorophyll b, and total chlorophyll), biochemical constituents (total sugar, amino acid, and protein content), mineral content (macro- and micronutrients), and the activity of antioxidant enzymes (catalase (CAT), peroxidase (POX), and polyphenol oxidase (PPO)) were …

Cadmium-Induced Changes In The Growth And Carbonic Anhydrase Activity Of Chickpea, Syed Aiman Hasan, Barket Ali, Shamsul Hayat, Aqil Ahmad
Turkish Journal of Biology
The seedlings of Cicer arietinum, grown in sand culture, were supplied with 0, 50, 100 or 150 µM of cadmium in the form of cadmium chloride at 5, 15 or 25 day stage and assessed for specific characteristics, 10 days after each treatment. It was a general observation in all the samplings that length, fresh and dry mass of both root and shoot and activity of carbonic anhydrase in leaf decreased, whereas proline content both in leaf and root increased. The intensity of the damage was proportionate with the concentration of the metal but was prominent at the earliest stage …

Effect Of Nigella Sativa Extract And Oil On Aflatoxin Production By Aspergillus Flavus, Anwar Maraqa, Najwa F. Al-Sharo'a, Husni Farah, Wafa M. Elbjeirami, Ashok K. Shakya, Abdul-Karim J. Sallal
Turkish Journal of Biology
: Crude extract of Nigella sativa, N. sativa oil, ground coffee beans and caffeine were tested for their effects on aflatoxin production by Aspergillus flavus. Crude extract of N. sativa inhibited the production of three types of aflatoxins (B1, B2 and G1) at 5% (w/v) concentration, while N. sativa oil inhibited all four types of aflatoxins using 3% (v/v) concentration. However, coffee inhibited the production of B1, G1 and G2 aflatoxins at 6% (w/v), while caffeine inhibited only G1 and G2 aflatoxin. Our results suggest the investigated ingredients may have a significant fungal antitoxic activity which can be exploited as …

The Abundance Of Arbuscular Mycorrhizal Fungi Spores In Rhizospheres Of Different Crops, Ali Akbar Safari Sinegani, Zahed Sharifi
Turkish Journal of Biology
The number of spores of vesicular-arbuscular mycorrhizal (VAM) fungi occurring in the rhizospheric soil of 14 crops was investigated using traditional wet-sieving/decanting methods. The aim of the study was to determine the effect of some agronomy species (Gramineae, Leguminosae, Solanaceae, Labiatae, Cruciferae, Umbellifera, and Alliaceae) on VAM spores numbers in the rhizosphere. The agronomy species were planted under greenhouse conditions in pots containing semiarid soil. The number of spores in the rhizosphere of each species was studied at the middle and end of vegetative plant growth. In the middle of vegetative growth the number of spores increased significantly in the …

Turkish Journal of Biology
Aqueous and ethanol extracts of Avicennia marina (Forsk.) Vierh. plant parts, namely leaves, stem and pneumatophore, were tested for their nematicidal activity against root knot nematode Meloidogyne javanica (Treub) Chitwood. Results showed that A. marina exerted more lethal effect in mortality of juveniles compared to hatching of juveniles. Stem showed more nematicidal effect compared to leaves and pneumatophore in aqueous extract, whereas pneumatophore showed more nematicidal activity in ethanol extract. Soil amendment at the rates of 0.1, 1 and 5% w/w was carried out with dried powder of leaves, stem and pneumatophore of A. marina for the control of root …

Electron Affinities, Solvation Energies And Redox Potentials Of Some Chalcones: Substituents` Effect And Correlation With Semi-Empirical Mo Energies, Abdur Rahman, Rumana Qureshi, Mehvish Kiran, Farzana Latif Ansari
Turkish Journal of Chemistry
Experimental and theoretical investigations were carried out on 2 sets of chalcones. Set 1 has an OH group on ring A and Set 2 does not, and both have different substituents on ring B at different positions. The experimental investigations comprised cyclic voltammetric (CV) studies to determine the reactivity in terms of redox potentials in DMF at room temperature (23 \pm 1 °C). Electrochemical parameters from cyclic voltammograms were used to evaluate the reversibility of electron transfer, standard reduction potentials, solvation energies, electron affinities, diffusion coefficients, critical scan rates and heterogeneous electron transfer rate constants. Heterogeneous electron transfer rate constants …

An Electrochemical Dna Biosensor For The Detection Of Dna Damage Caused By Radioactive Iodine And Technetium, Pinar Kara, Kağan Dağdevi̇ren, Mehmet Özsöz
Turkish Journal of Chemistry
A DNA damage process by radioactive iodine (I-131) and technetium (Tc-99m) is described. The procedure relies on a label-free electrochemical DNA biosensor. Fish sperm double stranded DNA was immobilized onto a carbon paste electrode (CPE) by electro deposition and the changes to the guanine oxidation signal were observed upon exposure to radioactive I-131 and Tc-99m by differential pulse voltammetry (DPV). The changes to the signal of guanine after exposure to therapeutic doses of Tc-99m and I-131 showed conformational changes in DNA molecules.

Turkish Journal of Chemistry
Di-(1, 3, 8) and triorganotin(IV) complexes (2, 5, 7) with the general formula R_nSnL_{4-n}, where R = Me, Et, n-Bu, n-Oct, Ph, and Bz, and L = the n-C_4H_9OCOC_6H_4COO^- monoanionic ligand have been synthesized by the reaction of the silver salt of the n-butylhydrogen phthalate with di- and triorganotin chloride in dry chloroform. However, di-n-butyl- and di-n-octyltin(IV) derivatives (4 and 6, respectively) were synthesized by the reaction of the corresponding organotin(IV) oxide with n-butylhydrogen phthalate in dry toluene. All the synthesized complexes were characterized by elemental analysis, FT-IR, multinuclear (^1H, ^{13}C, ^{119}Sn) NMR, and mass spectrometric techniques to assess the …

Selenium And Trace Element Distribution In Astragalus Plants: Developing A Differential Pulse Polarographic Method For Their Determination, Güler Somer, A. Cengi̇z Çalişkan
Turkish Journal of Chemistry
Astragalus plants have a wide range of applications in pharmaceuticals (gum tragacanth), as thickening agents in foods, and may have applications in controlling cancer cells. They are used as feed for animals and they are indicator plants for selenium. Because of their use in health-related areas it is very important to determine their selenium and trace element content with high accuracy. A new differential pulse polarographic method was established for trace element determination (10 elements) and their distribution in these plants. The Astragalus plants investigated in this work are Astragalus microcephalus and Astragalus lusitanicus, which grow almost everywhere. Their roots, …

Preparation, Spectroscopy, Antimicrobial Assay, And X-Ray Structure Of Dimethyl Bis-(4-Methylpiperidine Dithiocarbamato-S,S`)-Tin(Iv), Zia-Ur Rehman, Saira Shahzadi, Saqib Ali, Guo-Xin Jin
Turkish Journal of Chemistry
Dimethyl bis(4-methylpiperidine dithiocarbamato-S,S')-tin(IV) was synthesized and characterized by elemental analysis, IR and mass spectrometry, multinuclear NMR (^1H- and ^{13}C-NMR), and X-ray single crystal analysis. IR data showed that the ligand acts as a bidentate in the solid state. X-ray data showed the unsymmetrical nature of the ligand towards coordination to tin. It crystallized in the monoclinic P2_1/n space group. Its geometry is distorted octahedral. Antimicrobial activity data shows that the complex exhibits significantly more activity than the free ligand.

The Synthesis Of 2-(Chloromethyl)-6-Hydroxy-2h-Pyran-3 (6h)-One Via Achmatowicz Rearrangement, Zuhal Gerçek
Turkish Journal of Chemistry
Achmatowicz rearrangement was carried out with 2-chloro-1-(furan-2-yl) ethanol, which was synthesized starting from 1-(furan-2-yl) ethanone. It was shown that the oxidation of 2-chloro-1-(furan-2-yl) ethanol with m-CPBA produced 2-(chloromethyl)-6-hydroxy-2H-pyran-3 (6H)-one in good yield (70%).
