Abstract: Bioactive proteins represent an important group of functional agents in medicinal mushrooms. Trametes versicolor (L.) Lloyd is a mushroom frequently used in traditional Chinese medicine for its anti-tumor and immunomodulatory activities. A new immunomodulatory protein from T. versicolor, named TVC, was purified by ammonium sulfate precipitation, ion-exchange chromatography and gel filtration chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of the purified protein revealed a single band with a molecular weight of 15.0 kD. Native polyacrylamide gel analysis revealed a band at 30 kD, indicating that TVC exists in solution as a homodimer. Isoelectric focusing showed that TVC was an acidic protein with an isoelectric point of 4.0. TVC was found to lack carbohydrate modifications (based on periodic acid/Schiff staining) and it does not agglutinate mouse red blood cells, suggesting that TVC is not a lectin-like protein. Biological activity assays demonstrated that TVC can enhance the proliferation of splenocytes, while it has no stimulatory effects on CD4+ and CD8+ T cells. TVC markedly increases the proliferation of human peripheral blood lymphocytes in a dose-dependent manner and enhances the production of both nitric oxide and tumor necrosis factor-alpha by lipopolysaccharide-induced murine macrophages. The results indicate that TVC is an immunostimulant that can boost immune response. Comparison of the N-terminal amino acid residues and mass spectrometry results with the protein database revealed no homologous proteins.

Discussion boards are one method of online asynchronous learning that facilitates active learning and participation. We hypothesized that an online repository of best practice articles with a discussion board would increase journal article reading by emergency medicine residents. Methods: Participants answered three questions weekly on a discussion board: What question does this study address? What does this study add to our knowledge? How might this change clinical practice? A survey regarding perceived barriers to participating was then distributed. Results: Most participants completed an article summary once or twice in total (23/32, 71.9%). Only three were involved most weeks (3/32, 9.4%) whereas 5/32 (15.6%) participated monthly. The most common barriers were lack of time (20/32, 62.5%), difficulty logging on (7/32, 21.9%), and forgetting (6/32, 18.8%). Conclusion: Although subjects were provided weekly with an article link, email, and feedback, journal article reading frequency did not increase.

Effect of Sowing Media and Gibberellic Acid on the Growth and Seedling Establishment of Bougainvillea glabra, Ixora coccinea and Rosa chinensis. 2. Root Characters
AA Fagge, AA Manga
Bayero Journal of Pure and Applied Sciences , 2011,
Abstract: Two pot experiments were carried out in the screen house of the Faculty of Agriculture Bayero University Kano (Latitudes 80 421N and 90301N) during the wet and dry seasons of 2008/2009 to investigate the effects of Sowing Media and Gibberellic acid (GA3) concentrations on the growth and seedling establishment of three ornamental plant species. The treatments consisted of three sowing media (Top soil TS, mixtures of Top soil plus Poultry manure TS+PM and Top soil plus Sawdust TS+SD) in the ratio of 2:1, three GA3 concentrations (0, 100 and 200ppm) and three plant species (Bougainvillea, Ixora and Rose); factorially combined and laid out in a completely randomized design with four repetitions. The results indicated that TS+SD medium gave significantly (P<0.05) higher number of roots and root lengths per plant while the least was with TS+PM medium. TS and TS+SD media were significantly higher than TS+PM medium in terms of root fresh weight and root dry weight per plant. Application of GA3 at 100ppm compared to 0 and 200ppm concentrations gave significantly (P<0.05) better responses for all the root characters. The same trend was true for Bougainvillea compared to Ixora and Rosa. Hence, based on the outcomes of this experiment, combinations of TS+SD medium and GA3 at 100ppm concentration are recommended for better root establishment, growth. and development in relation to the three plants under study.

The results indicated that TS and TS+SD gave significantly (P<0.05) greater number of days to bud break, leaf area, leaf fresh weight and leaf dry weight per plant. Application of GA3 at 100ppm gave higher value of all the characters studied except number of days to bud break, where no significant difference was observed among the different concentrations. Bougainvillea was significantly (P<0.05) higher than the other plants in all the characters except days to bud break. The Combination of TS+SD medium and GA3 at 100ppm concentration is recommended for the good growth and development of the shoot characters.

Abstract: the optimal condition of broiler chickens at the moment of slaughter should be known in order to produce the highest quality meat. several and related pre- and post-slaughter factors are involved in ultimate poultry meat quality. in normal operation, feed is withdrawn from birds 6 to 8 hours before catching, resulting in a feed and water withdrawal total period of 8 to 12 hours prior to slaughter, in order to empty the digestive system and minimise fecal contamination. the most critical points for cross-contamination are scalding, plucking and evisceration, due the great amount of micro-organisms present in skin, feather and feet, and due to intestine breakage during evisceration. however, carcass dehydratation begins immediately after feed withdrawal, and a prolonged period without feed and water can affect ph of the gut, increasing salmonella and other pathogenic micro-organisms. in addition, excessive feed and water withdrawal times increases bile contamination and are often subjectively associated with increased intestinal fragility during automated evisceration. thus, processing schedules need to be established to take in account feed withdrawal on gut integrity and fullness, gall bladder status, birds welfare, shrinkage and subsequent effects on carcass contamination and meat quality. as some effects of feed and water withdrawal are still unknown, research is required in the following area: optimal feed and water withdrawal time in relation to welfare of the birds, carcass contamination, and meat quality parameters; influence of delayed withdrawal on ph and colonization of crop, proventriculus, gizzard, small intestine, colon and ceca by enterobacterias like salmonella; influence of feed and water withdrawal on liver weight and colour. the expected result is an improvement in animal welfare and meat quality, while reducing losses and costs.
The English Primary Auxiliary Verbs: A Linguistic Theoretical Exercise
AA Alagbe
African Research Review , 2009,
Abstract: Obviously, the fact remains that English Language is a sensitive Language that cannot be ignored by any one, most especially, in Nigeria where the said language is used officially for effective communication. This is why speakers of this language need to be conscious of what kinds of sentence they use in communication with other people in the environment which they find themselves. This paper aims at carrying out linguistic theoretical exercise as regards the use of the English primary auxiliary verbs. The paper also aims at exposing the rate at which speakers of English Language misuse the English primary auxiliary verbs. The traditional grammar alongside structural grammar was used to analyze the numerous uses of the English auxiliary verbs by our subjects.
