SYNTHESIS AND STRUCTURAL FEATURES OF COPPER(II) COMPLEXES OF BENZOIC ACID AND METHYL SUBSTITUTED BENZOIC ACID HYDRAZIDES AND X-RAY STRUCTURE OF Cu[C6H5CONHNH2]2(NO3)2

Abstract: The synthesis, spectroscopic, magnetic and biological activities of copper(II) complexes of benzoic acid hydrazides (BAH) and o, m, and p-substituted methylbenzoic acid hydrazides (MBAH) and the single crystal X-ray structure for bis(benzoic acid hydrazide)copper(II) nitrate {Cu[BAH]2-(NO3)2} (BAH=Benzoic acid hydrazide) are reported. The composition of the ligands was established by elemental analyses, 1H NMR, and GC-MS. Magnetic susceptibility, electronic and infrared spectral data are consistent with a mononuclear square-planar geometry with bidentate coordination of the hydrazide ligands to give essentially a CuN2 2 chromophore. Cu[BAH]2(NO3)2 crystallizes from methanol solution under ambient temperature in a monoclinic system with a P21/c space system. The copper atom has a nearly regular, four-coordinated, square-planar arrangement with the nitrate anions being uncoordinated in the crystal lattice. The compounds did not show significant activity against selected bacteria and fungi.

Prevalence of multiple antibiotic resistance among bacterial isolates from selected poultry waste dumps in Southwestern Nigeria

Abstract: The prevalence of multiple antibiotic resistant bacteria in the waste dumpsite of ten poultry farms in Southwestern Nigeria was investigated. The susceptibility of 195 organisms isolated from the study sites to eight antimicrobial agents were tested using disc diffusion method and the minimum inhibitory concentration of cloxacillin and amoxicillin determined by the agar dilution method. Resistance to the test antibiotics ranged between 0% for gentamicin and 100% for tetracycline and ampicillin among the organisms. Overall, 70 and 90% of the isolates from Okuku, 65.2 and 95.6% from Ogbomoso, and 46.1 and 84.6% from Oyo had MIC above 512 μg/ml for amoxicillin and cloxacillin. Generally, drugs used in high volumes in the studied farms are the least active against the bacterial isolates. Results of this study shows that poultry waste can serve as environmental reservoirs of multiple antibiotic resistant bacteria and their indiscriminate dumping in the environment can expose surrounding human populations to health risks from drug resistant zoonotic pathogens.

Tomato (Lycopersicon esculentum) prevents lead-induced testicular toxicity.

Abstract: Background: Lead, an example of heavy metals, has, for decades, being known for its adverse effects on various body organs and systems such that their functions are compromised. Aim: In the present study, the ability of lead to adversely affect the male reproductive system was investigated and tomato ( Lycopersicon esculentum : Source of antioxidants) paste (TP) was administered orally to prevent the adverse effects of Pb. Materials and Methods: Fifteen Sprague Dawley rats, randomised into three groups (n = 5), were used for this study. Animals in Group A served as the control and were drinking distilled water. Animals in Groups B and C were drinking 1% Pb (II) acetate (LA). Group C animals were, in addition to drinking LA, treated with 1.5 ml of TP/day. All treatments were for 8 weeks. Statistical Analysis Used: A Mann-Whitney U -test was used to analyse the results obtained. Results: The obtained results showed that Pb caused a significant reduction in the testicular weight, sperm count, life-death ratio, sperm motility, normal sperm morphology, and plasma and tissue superoxide dismutase and catalase activity, but a significant increase in plasma and tissue malondialdehyde concentration. But, Pb did not cause any significant change in the serum testosterone level. TP, however, significantly reduced these adverse effects of Pb. Conclusion: These findings lead to the conclusion that TP significantly lowered the adverse effects of Pb exposure on the kidney as well as Pb-induced oxidative stress.

Value added cassava waste management and environmental sustainability in Nigeria: A review

Abstract: Nigeria is the highest producer of cassava in the World with concomitant generation of millions of tons of solid and liquid wastes. These wastes are indiscriminately disposed into the environment causing degradation with attendant serious health hazards to both flora and fauna. There is need, therefore, to properly manage these wastes for sustainable environment. In this review, research efforts focusing on effective management of cassava solid and liquid wastes are highlighted. Laboratory-scale successes so far recorded in the application of cassava peels as adsorbent for the treatment of various grade of industrial wastewater as well as its potential use as animal supplement are analyzed. Studies showing the potentials of cassava peels and wastewater in the production of biofuels, bio-electricity via the microbial fuel cell (MFC) and value added bio-based chemical by-products are enumerated. Current research works on the viability of the dual role of cassava wastewater based microalgae cultivation; the shortcomings and suggestion for improvement of the technology are equally reviewed. However, to maximize these research findings for environmental sustainability, it is suggested that the Nigerian government and relevant stakeholders should invest more on research and development (R&D) in the area of cassava waste management and encourage investors to venture into the sector
