Abstract:

This study was conducted to investigate the effects of different levels of a water-soluble polysaccharide extract from brown algae, Padina australis (WPP) on growth, antioxidant enzymes activities and nonspecific immune responses of shrimp, Litopenaeus vannamei . Three replicate groups of shrimp (1 ± 0.1g) were fed four isonitrogenous and isolipidic diets containing four levels, 0 or control, 0.5, 1.0, and 1.5 g kg-1 of WPP for 8 weeks. Results show that the diet containing 1.0 g kg-1 of WPP had a significant positive effect on growth performance of shrimp. In addition, the activities of antioxidant enzymes including superoxide dismutase, glutathione peroxidase, catalase and malondialdehyde improved by feeding 0.5 and 1 g kg-1 of WPP. Also, the lysozyme and phenoloxidase activities in those of shrimp fed 0.5 and 1 g kg-1 of WPP were significantly higher than those fed control and 1.5 g kg-1 WPP. These results suggested that the use of 1.0 g kg-1 of water-soluble polysaccharides of P. australis can be beneficial for growth, antioxidant and nonspecific immune of L. vannamei.

Title: Effect of dietary supplementation of Chlorella vulgaris on growth, antioxidant defense and immune status of grey mullet, Mugil cephalus
Biography:

Abstract:

The objective of the study was to examine the effects of dietary supplementation of Chlorella vulgaris powder (CP) on growth, antioxidant enzyme activity, immune responses of juvenile Mugil cephalus. Fish (15 ± 0.1g) were fed diets enriched with 0 (control), 5, 10 and 15 g CP per kg feed for 8 weeks. After the feeding trial, fish were challenged against pathogenic bacteria (Photobacterium damselae) infection to evaluate disease resistance of infected fish. Fish growth performance was significantly improved with increasing CP levels at CP10 and CP15. Antioxidant-stimulated activity was observed with dietary CP where total antioxidant capacities (TAC), superoxide dismutase (SOD) and glutathione (GSH) increased, while malondialdehyde (MDA) decreased significantly in fish fed CP. Furthermore, serum lysozyme activity of fish fed three levels of CP was significantly higher than control group. In addition, CP supplementation at 10 and 15 g dose induced kidney phagocytic and respiratory burst activity which was maximized at 15 g CP. Meanwhile, feeding 10 and 15 g of CP diets decreased mortality in M. cephalus after challenge with P. damselae.

Abstract:

Statement of the Problem: Tuberculosis (TB) is one of the top 10 causes of death worldwide. The severity of pulmonary TB symptoms is affected by the immune status which is strongly influenced by nutrition. Immunonutrient can be defined as the effect of the provision of specific nutrients on immune function. Vitamin D is known to enhance immune response to mycobacteria. In addition, protein products cytokine which help body defense to mycobacteria. The aim of this study was to determine the effect vitamin D and protein intake as the immunonutrient on severity of pulmonary tuberculosis clinical symptoms. Methodology & Theoretical Orientation: The method of this study is cross sectional study of 52 pulmonary tuberculosis patients. They were interviewed with questionnaire of FFQ. The amount of vitamin D and protein intake is calculated by using the nutrisurvey. Clinical symptoms of TB patients are measured by using Bandim TBScore. Statistical analysis of the two variables is allegedly linked using SPSS. Findings: The average intake of vitamin D is 5.86 mcg/day, SD 5.45 . The average intake of protein is 78,477 gram/day, SD 29,30. The respondents who have degree TBScore I is 92.3% (48 persons), TBScore II is 7.69% (4 persons),  TBScore III is 0% (0 persons). The average of TBScore is 2,04 ± 1,89. Conclusion & Significance: Based on the statistical analysis, vitamin D and protein intake are not significantly affect the severity of pulmonary TB clinical symptoms. However, the average intake of TBScore II group is much lower than the intake of TBScore I group.

Abstract:

This work was instigated by a certain comparative study drawn on immunogenic biological therapy and its clinical relevance on Psoriatic Arthritis delivered in a conference in 2016. The work which projected a comparative biological understudy of anti-inflammatory biologic activities as a catalysis on significant determinant in addressing diseases life activities in Psoriatic arthritis (PsA) especially, emphatic in the cases of joint infection, held that the residues of protein presences in biologics pre-disposes the capacities to re-create anti-drug antibodies (ADAbs) which may stimulate clinical investigation result. However, a critique look on the disparity of levels and frequencies of occurrences of ADAb formations, potentiate effects on safety and efficacy of texts, journals and articles sighted, theirs and others demonstrated a different level of result and outcome throwing up reason for further questions.
