Schiff base complexes of general formula [M(MDES)2X2] where M = Co(II), Ni(II) and Cu(II), MDES = 1-methyl- 2, 6 diethyl piperidone semicarbazone and X = Cl-, Br-, I- and NO3 -, have been synthesized. The ligand as well as metal complexes were characterized by elemental analyses, IR spectra, electronic spectra, molar conductivity and magnetic susceptibility measurements. On the basis of above observations it has been observed that ligand acts as neutral bidentate manner and coordination proposed through azomethine nitrogen and carbonyl oxygen of semicarbazone moiety. The remaining coordination centres are satisfied by anions such as Cl-, Br-, I- and NO 3 -. On the basis of electronic spectral data and magnetic susceptibility data the gometry of the complexes tentatively proposed octahedral. Antibacterial activity of ligand and complexes were also determined. Source

A series of complexes of the type [M(EHPQH)2X2] where M = Co(II), Ni(II) and Cu(II), EHPQH=2-ethyl, [3(hydroxypropyl)]-3, 1 4H quinazoline -4-hydrazone, X= Cl-, Br-, I- and No-3 -. The geometry of the complexes have been elucidated in the light of molar mass, elemental analysis, IR, electronic Spectra, molar conductance and magnetic susceptibility. The measured molar conductance value indicates that the complexes are non-electrolytic in nature. The above observation indicates that Schiff bases EHPQH behave as bidentate ligand and coordination proposes through azomethine N and oxygen atom of alcoholic group of ligand. The remaining coordination sites are satisfied by negative ion such as Ci-, Br-, I- and NB-. The geometry of the Co(II) and Ni(II) were proposed to be octahedral in geometry whereas Cu(II) complexes were proposed to be distorted octahedral. The Schiff bases and its complexes have been evaluated for their antibacterial activity. The complexes show enhanced antibacterial activity than ligand. Source

Colorectal cancer is a common disease in both men and women (being the third most common cancer in men and the second most common among women) and thus represents an important and serious public health issue, especially in the western world. Although it is a well-established fact that cancers of the large intestine produce symptoms relatively earlier at a stage that can be easily cured by resection, a large number of people lose their lives to this deadly disease each year. Recent times have seen an important change in the incidence of colorectal cancer in different parts of the world. The etiology of colorectal cancer is multifactorial and is likely to involve the actions of genes at multiple levels along the multistage carcinogenesis process. Exhaustive efforts have been made out in the direction of unraveling the role of various environmental factors, gene mutations, and polymorphisms worldwide (as well as in Kashmir-"a valley of gastrointestinal cancers") that have got a role to play in the development of this disease so that antitumor drugs could be developed against this cancer, first, and, finally, the responsiveness or resistance to these agents could be understood for combating this global issue. © 2014 International Society of Oncology and BioMarkers (ISOBM).

To carryout surface water quality of the area, samples from 4 different ponds were taken during monsoon season, post-monsoon, winter season and pre-monsoon in year 2012-13. The studied water bodies (ponds) are located near about an integrated steel and power plant in new Raipur area, Chhattisgarh. The water quality parameters, like pH, TDS, total hardness, alkalinity, chloride, fluoride, sulphate, nitrate, calcium, magnesium and iron were analyzed in the present study. The pH, TDS, total hardness, alkalinity, chloride, sulphate, nitrate, calcium and magnesium were analysed in the the prescribed norms. Fluoride concentration in sample SW1, SW2 and SW4 found slightly higher than desired limit but under permissible limit as prescribed by Bureau of Indian Standard (2012). Iron was found in range between 0.54 to 1.24 mg/L which is higher than permissible limit in all the samples. The higher concentration of iron may be due to deposition of iron mixed suspended particulate matter from atmosphere to surface, that is emitted from nearest an integrated steel and power plant. Maximum iron concentration found in the sample SW1 (Serikheri pond) which is located in the downwind direction with respect to the plant where dispersion of air pollutants may be greater than other location. ©2015 - Kalpana Corporation.

Organophosphate pesticides widely used all over the world to control pest. They ultimately make their way into aquatic habitat and proved harmful to fishes and other aquatic flora and fauna. Organophosphate insecticides that kills insects by disrupting their nervous system and is effective against a wide range of plant eating insects. In the present study effect of sub lethal concentration of chlorpyrifos on oxygen carrying capacity of blood in fish, Channa punctatus (Bloch.). The study showed a significant decrease in the oxygen carrying capacity of blood after 24hrs. 48hrs.,72hrs. and 96hrs. respectively, when compared to control group. Source
