Study Design: Pigs were subjected to management treatments that may promote stress, like Original Research Article Oliván et al.; BBJ, 11(1): 1-13, 2016; Article no.BBJ.22402 2 mixing unfamiliar animals on farm and/or during transport and lairage before slaughter. Three preslaughter treatments were applied: UF-UTL (Unmixed on Farm Unmixed during Transport and at Lairage), MF-UTL (Mixed in Farm Unmixed during Transport and at Lairage) and MF-MTL (Mixed in Farm Mixed during Transport and at Lairage). Methodology: Fifteen entire male pigs were used in this experiment. At slaughter, blood samples were taken for biochemical analysis. Meat quality traits (pH, electrical conductivity, drip loss, meat colour) were measured and muscle samples from the Longissimus thoracis were taken within the first 24 h post-mortem and used for analysis of total antioxidant activity (TAA) and sarcoplasmic protein profile study by SDS-PAGE. Results: Mixing treatments (MF-UTL and MF-MTL) provoked faster muscle pH post-mortem decline (P= .009), lower total antioxidant activity (P< .001) and changes in some key proteins, like the heat shock 70kDa protein-1B (P= .040), glyceraldehyde-3-phosphate dehydrogenase “GAPDH” (P= .047), lactate dehydrogenase-A “LDH-A” (P< .001) and adenylate kinase isoenzyme-1 “AK-1” (P< .001). Furthermore, serum molecules related to fat metabolism (LDL-cholesterol and triglycerides) and changes of muscle proteins involved in the adenine nucleotide metabolism (AK-1) and glycolysis regulation (piruvate kinase “PK” and GAPDH) allowed accurate prediction of muscle pH and discriminated correctly 87% of meat samples into “no-mixing” or “mixing” treatments. Conclusions: Early monitorization (within 24 h after slaughter) of selected biomarkers could be used in the meat industry as a tool for detection of situations of pre-slaughter stress related to animal mixing practices. However more research is needed in order to validate these results on a broader animal population.","PeriodicalId":90120,"journal":{"name":"British biotechnology journal","volume":"11 1","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71164102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: Aerial parts of S. nigrum and C. gynandra collected from wild populations were extracted in water and methanol solvents using the cold maceration procedure. Chemical tests to identify different phytochemicals and antinutrients were carried out using specified reagents. Toxicity of the plant extracts was tested using the Brine Shrimp (Artemia salina) lethality bioassay procedure. Results: Phytochemical tests indicated presence of alkaloids, steroids, flavonoids, cardiac glycosides, saponins, phenols and tannins in both S. nigrum and C. gynandra. Anthraquinones were only found in C. gynandra, whereas terpenoids and coumarin glycosides were found only in Original Research Article Sango et al.; BBJ, 13(3): 1-11, 2016; Article no.BBJ.25164 2 S. nigrum. The anti-nutrient levels in the vegetables were high; tannins (3.580 and 1.820 mg/ 100 g), oxalates (21.560 and 24.97±0.156 g/100 g), saponins (71 and 42%), alkaloids (15.160 and 3.44%) and phytates (0.099±0.046 and 0.250±0.013%) in S. nigrum and C. gynandra respectively. The Brine Shrimp LC50 values obtained were 0.67 and 1.84 mg/ml for methanol and water extracts of S. nigrum and 1.09 and 4.9 mg/ml for C. gynandra, respectively. Conclusion: The vegetables, C. gynandra and S. nigrum are rich sources of diverse phytochemicals. However, some phytochemicals are present in high levels and might act as anti nutritional factors interfering with absorption of food. C. gynandra is safe for consumption but S. nigrum contains some toxic phytochemicals and should not be taken regularly.","PeriodicalId":90120,"journal":{"name":"British biotechnology journal","volume":"13 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71164619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: Halobacterium sp. NRC-1 was used as halophilic species and Gram-positive bacterium Bacillus subtilis, and radiation resistant bacterium Deinococcus radiodurans were used as non-halophilic species. The three species were selected because their proteins were closely Original Research Article Nakashima et al.; BBJ, 14(2): 1-12, 2016; Article no.BBJ.25207 2 related each other. The amino acid compositions were compared and the amino acid substitutions were counted for the orthologous protein pairs between Halobacterium and B. subtilis. Similar comparison was done for the proteins between Halobacterium and D. radiodurans. Results: The Asp and Glu residues are determinant whether a protein of Halobacterium sp. NRC-1 is acidic or basic. Amino acid substitutions to increase the Asp residues in the acidic proteins of Halobacterium from the corresponding proteins of non-halophilic species were almost identical whether the corresponding proteins were acidic or basic. This result suggested that the change of protein charges from basic proteins to acidic ones was same as from acidic proteins to acidic ones. The proteins of Halobacterium showed a tendency to have residues with smaller side chain than the proteins of B. subtilis / D. radiodurans.","PeriodicalId":90120,"journal":{"name":"British biotechnology journal","volume":"14 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71164681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
