  Increased ROS in prostate cancer cells has been associated with cellular proliferation; however, the roles of ROS during invasion or metastasis are less well defined. While proliferation leads to higher density, invasive cells leave the cell mass and exist in a lower density state. Our aim was to determine if ROS levels vary with cell density and determine if ROS play a role in motility, adhesion or invasion. We found that ROS are increased in prostate cancer cells grown at low density and that this increase was particularly apparent in migrating cells. Inhibition of ROS reduced cell motility, adhesion to matrix substrates and invasion through Matrigel. Catalase activity was found to be down-regulated at low density but SOD activity and glutathione ratio were unaltered. Reduced catalase activity may contribute mechanistically to increased ROS at low density and this ROS appears to promote motility, adhesion and in vitro invasion.

  A total of 31 selection indices were constructed on five characters in 33 diversed genotypes of sorghum (Sorghum bicolor L.). High heretability couple with high genetic advance expected in the next generation and association of characters were the basis for choosing of the characters for discriminant function analysis. Green fodder yield and grain yield have to be simultaneously improved through selection. Amongst the single character selection indices, grains/panicle offered maximum genetic worth (11.51). In general, inclusion of every character in the function, exerted a progressive relative efficiency over straight selection. The highest relative efficiency over straight selection on grain yield alone was realized while grain yield/plant (x1), fodder cutting maturity (x2), green fodder yield/plant (x3), digestible dry matter/plant (x4) and grains/panicle (x5) were concurrently integrated in the function.

  A trail was conducted to investigate the effect and economic evaluation of feeding urea-molasses and urea-molasses concentrate with green grass on milk yield. Sixteen animals were grouped in to 3 having 5 animals in each of group A and C and 6 animals in group B. Group A was control (farmer practice), B was fed urea-molasses with green grass and C was fed urea-molasses concentrate with green grasses. The average milk yield of group A, B and C were 0.82, 2.67 and 1.87 kg/d and 4% fat corrected milk yield (FCM) of group A, B and C were 2.54, 6.99 and 4.78 kg/d respectively. The both average milk yield and FCM yield of group A was significantly (P<0.001) lower than treated groups B and C. Supplemented group B was significantly higher than supplemented group C. Total feed cost in group B (TK.1140) was lower than that of group C (TK.1305). In contrasts , net return from B (TK.5950) was higher than that of group C (TK.3658). In addition, another metabolic trail was carried out to find out the reason of better performance of urea-molasses supplemented group than urea-molasses concentrate group. Four cannulated animals were fed four types of dietary group, A, B, C and D respectively and was observed the ruminal parameters (NH3, pH) NH3-N was significantly higher (P<0.05) in dietary groups C and D than in dietary groups A and B. Addition of urea increased rumen NH3 level and maintain rumen pH in normal range. This favorable environment of rumen may recovered the deficit nutrients (energy, protein) of normal local grasses and increased milk production.

  This experiment was conducted to estimate the yield and nutritive value of common roadside grasses available in Bangladesh. A land was developed as an experimental plot and made for growing roadside grasses and was partitioned into four quarters each of 200 sq.m. Pasture was established as a grazing land. The average herbage yield (DM and OM) recorded in the month of November was significantly (P<0.05) higher than that of August, September or February. The fresh yield (P<0.05) and CP yield of Phaseolus mungo were significantly higher than that of other grass species. The OM content of Imperata cylindrica was significantly (P<0.05) than other grasses. The DM content of Cynodon dactylon and Imperata cylindrica, NDF content of Cynodon dactylon and CP content of Phaseolus mungo were significantly (P<0.01) higher than other grass species.

  Survey method was used to find the effect of shrimp culture on livestock production. The study area is located in the south-western part of Bangladesh in the tidal flood plain near the large mangrove forest, the sundarbans. The average livestock (cattle, goat, sheep, buffalo) number (per farmer), milk production (kg/day/cow), lactation period (day), birth wt. (kg) are significantly higher before shrimp culture compared to after shrimp culture but mortality percentage are significantly higher after shrimp culture compared to before shrimp culture. Livestock population and its overall conditions were better before shrimp culture compared with after shrimp culture. The study has revealed that the production of livestock have been affected following the shrimp farming practices in the study areas. Shrimp farming interacts with the environment and its expansion destroyed whole ground in coastal region.

  A total of 15 young rabbits (kits) of 35 days old were randomly allocated to same concentrate mixture (T2) in a completely randomized design. All the rabbits were offered ad-libitum green grass with same concentrate mixture. All the animals were kept in the same management. The feed intake, live weight changes and feed conversion efficiency was recorded. DM intake in three different groups (A, B, C) were 350.53?46.57, 403.62 ± 41.89 and 389.30 ± 53.71 (g/wk) which were not significant. The average daily gains in group A, B and C were 11.25 ± 8.71, 15.20 ± 8.33 and 14.43 ± 9.84 respectively and the differences among groups were not significant. The differences in growth velocity among different groups were not significant. Feed conversion efficiency were 4.45, 3.79 and 3.85 for group A, B and C respectively and the values were found non-significantly different. The result indicated that feeding of mother in terms of energy did not have any significant effect on DM intake, live weight changes, growth velocity and feed conversion efficiency upon their kits.

  Patterns of morphological variation in Hordeum species were determined by metroglyph analysis which revealed apparently four clusters comprising more than one line out of 15 studied. Cluster I was comprised of Centinella and Conquest of H. vulgare. Cluster II was comprised of single line of H. nudum and four lines (API-19, BEL-34, BEL-72 and BTON-10) of H. vulgare. Cluster III and IV were consisted of BEL-4, BTYN-8 and BTYN-37 and BEL-16, BHV-1, BHV-91, BHV-95 and BHV-105 of H. vulgare respectively. These clusters showed distinct graduation for breadth of flag leaves i.e., low (cluster I), relatively low (cluster III), intermediate (cluster II) and high (cluster IV). The ray`s pattern for 11 morphological characters on the glyph among the clusters revealed a marked variation for the presence or absence of rays.

  A total of 144 day old straight run Arber Acres broiler chicks were fed ad libitum up to 42 days of age on 4 isonitrogenous and isoenergetic diets formulated by replacing dietary fishmeal (FM) by silkworm pupae (SWP) up to 42 days of age. Four diets; D0 (6% FM + 0% SWP), D1 (4% FM + 2% SWP), D2 (2% FM + 4% SWP) and D3 (0% FM + 6% SWP) were fed to observe the effect of dietary SWP on performance. The growth rate, feed conversion, livability, meat yield and profitability increased almost linearly on increasing level of SWP.

  Floral biology and yield performance of different Snake gourd (Tricosanthes cucumerina L. syn. T. anguina L.) genotypes were investigated to develop high quality and yielding variety/ies. There were differences between the snake gourd genotypes in respect of floral biology and yield potentiality. Starting of the anthesis occurred within 7 to 8 pm in male flowers and required 19 to 33 minutes for full blooming. The anthesis of the female flower started from 7 to 8 pm and completed their full blooming within 1 to 2 h. Time of anther dehiscence started from 4 pm to 5 pm i.e. about 3 h before anthesis and completed at 7 to 8 pm. The fresh pollen viability percentage was around 99.00 and no pollen grain was germinated before 5 h at field condition. The stigma became receptive about 15 h before anthesis and it remained receptive upto 27 h after anthesis. SG 04 was more cross compatible than the self compatible

  This study was undertaken to find out the milk fat production trend both in qualitative and quantitative aspect and seasonal effect on it at Sree-Nagor Milk Shed Area (MSA) under Milk Vita in Munshigonj, Bangladesh. The experiment was conducted during the period of 1995 to 1999. Season had the tremendous effect on milk yield (l/d). The milk production showed highest in the month of June, lowest in January, August, September and December; but in other months of the year it seemed almost similar. However, the average fat value of milk at Sree-Nagor MSA followed almost a specific trend throughout the year. Furthermore, the average fat value of Sree-nagor MSA was in-significant (P>0.05) between different months of the experimental period, but that of each year (1995-1999) between different months were highly significant (P<0.01), which means that season has large effect on fat value.

  The present study examines the consumption pattern of milk and milk products among different income groups in some selected areas in Bangladesh. Family budget data were collected through household survey during September` 01 to May 2002 for 179 selected households from the three different areas of Bangladesh, comprising 44 from Rural, 61 from Municipality town and 74 from Metropolitan city households formed the basis. The sample households were post classified into 5 income groups based on monthly household income as follows: (I) < Tk. 3000; (II) Tk. 3001-6000; (III) Tk. 6001-9000; (IV) Tk. 9001-12000 and (V) >Tk. 12000. Among milk and milk products, the major allocation of expenditure was devoted to liquid milk followed by sweetmeats and powder milk and `other milk products`. The municipality town households consume more milk, sweetmeats and dahi than Rural and Metropolitan city. On the other hand, Metropolitan households consume more powder milk, condensed milk, ghee and ice cream. Milk and some milk products consumption and expenditure on it increased substantially, with the increase of income in all the areas.
