Abstract

The objective of the present study was to evaluate the in-vitro anti- cancer effects of methanolic extract of jackfruit (Artocarpus integrifolia) latex against MCF-7 human breast cancer cell lines by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazoliumbromide (MTT) method. The assay provides a convenient, sensitive, quantitative and reliable assay for determining the cytotoxic activity of test sample. The activity was evaluated at different concentration (100 μg, 250 μg, 500μg, 1000μg) of test material. Human breast cancer cell line MCF-7 was taken to see the cytotoxic activity of latex extract. Extract were added in different concentration from 100 μg, 500 μg, 750 μg, 1000 μg to MCF-7 Human breast cancer cell line. Twenty-four-hour exposure to Artocarpus integrifolia extract inhibits cell proliferation as compared with untreated cell. Growth Inhibition was noted 68.3 %, 74.4 %, 77.5 %, 79.9 % against the concentration 100 μg, 500 μg, 750 μg, 1000 μg of test sample respectively. Our results indicate that the plant has a promising anti-cancer activity. Further investigation for active compound present in Artocarpus integrifolia required for cancer management and for the development of new anti-cancer drugs.

Abstract

This paper gives a comprehensive account of the development of library and information science education in Africa. Ghana was first to start any kind of library education in 1944 but the formal education started at Ibadan, Nigeria in 1959. By 1970 there were 6 library schools; 4 new schools started during 1970s and another 6 during 1980s. Two Regional schools with Master's Programme in Information Science started in 1990. Two new schools are likely to start soon. Nigeria alone has 8 schools providing professional education at all levels including PhD (which is available only in Nigeria) and an exclusive programme of Master in Information Science at ARCIS, Ibadan. Several schools, realising the importance of new developments in information science and technology, are planning to incorporate this component into their curriculae. The existing programmes need to be assessed in the context of information needs of Africa.

Abstract

Biomass variation, secondary production and turn-over of the earthworm Drawida willsi (Michaelsen) was assessed from a tropical agroecosystem site at Ranchi for 18 months. The total biomass ranged between 0.88 ± 0.33 and 29.55 ± 3.15 g dry weight m^-2. Secondary production of 53.37 g dry weight m^-2 yr^-1 was obtained which in terms of calorific value amounts to 246.57 kcal m^-2 yr^-1. Biomass turnover value was 4.99.

Abstract

Fluctuation of population density of the earthworm Drawida willsi (Michaelsen) in relation to some climatic and edaphic factors was assessed from a tropical cropland agroecosystem site at Ranchi for a period of eighteen months. The total density ranged between 75 ± 25.49 (April 2010) to 2115 ± 189.87 m^-2 (August 2010). Of the various factors studied rainfall, relative humidity, soil moisture, organic carbon and nitrogen content of the soil showed a significant positive correlation with the total earthworm density. Moisture content of the soil was considered to be the most important single factor responsible for the population fluctuation of the earthworm.

Abstract

Moisture dependent physical properties of Bhatt (Black soybean) were evaluated in the moisture range from 8.67 to 25 per cent (d.b). The moisture content had significant effect on the physical properties of Bhatt. The length, width and thickness varied in the range of 4.87 to 7.8 mm, 3.12 to 5.5 and 2.34 to 4.02mm at moisture content of 8.67 per cent (db) to 25.00 per cent (db). The geometric mean diameter, sphericity, surface area and volume of the grain were in the range of 4.565 to 5.011mm, 0.704 to 0.723, 65.105 to 75.116mm² and 10.847 to 12.515mm³, respectively. Thousand Kernel weight varied from 59.89 to 66.84 g along with the associated standard deviation in the range of 1.562 to 7.739 at moisture content range of 8.67 per cent to 25.00 per cent (db). The bulk density and true density decreased with increase in the moisture content and were in the ranges of 646.48 to 695.35 kg/m³ and 1169.60 to 1193.40 kg/m³ along with associated standard deviation in the range of 1.300 to 2.479 for bulk density and 2.157 to 6.730 for true density, respectively. The value of porosity was found 0.417 at 8.67 per cent moisture content and 0.445 at 25.00 per cent moisture content.
