Actinobacteria can be utilized as biofertilizers for sustainable agriculture as they can enhance plant growth and soil health though different plant growth promoting attributes such as solubilization of phosphorus, potassium and zinc, production of Fe-chelating compounds, phytohormones hormones such indole acetic acids, cytokinin, and gibberellins as well as by biological nitrogen fixation. The Actinobacteria also plays an important role in mitigation of different abiotic stress conditions in plants. The members of phylum Actinobacteria such as Actinomyces, Arthrobacter, Bifidobacterium, Cellulomonas, Clavibacter, Corynebacterium, Frankia, Microbacterium, Micrococcus, Mycobacterium, Nocardia, Propionibacterium, Pseudonocardia, Rhodococcus, Sanguibacter and Streptomyces exhibited the multifarious plant growth promoting attributes and could be used as biofertilizers for crops growing under natural as well as under the abiotic stress conditions for plant growth and soil health for sustainable agriculture.","PeriodicalId":15033,"journal":{"name":"Journal of Applied Biotechnology & Bioengineering","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72872494","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}

This implies their continuous release into the environment may facilitate toxic effects both on humans and the environment including development of resistance strains, among others. This research was focused on the synthesis, characterisation and assessment of a tailor- made adsorbent: modified chitosan flakes, using several materials for the modification of chitosan to enhance its sorption properties thereby facilitating a higher percentage of TC removal from a synthetic pharmaceutical wastewater. TC adsorption onto the modified chitosan flakes was relatively fast (equilibrium time = 2h). Sorption studies revealed that TC removal by the adsorbent followed pseudo second order kinetics and Freundlich isotherm models. At higher TC input concentration, the amount of TC removed was also higher, this implied the sorption was concentration dependent. Insight into mechanism of sorption revealed cation exchange was an active means of interaction between the adsorbate and adsorbents moieties.","PeriodicalId":15033,"journal":{"name":"Journal of Applied Biotechnology & Bioengineering","volume":"127 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86679767","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}

Turmeric is a potential therapeutic agent, and used in the management of oxidative, and inflammatory conditions. There has been an immense interest in creatine and turmeric research over the years and they have been extensively studied. However, there have been no studies available on their combined effect at the cellular level. The purpose of this study was to investigate the individual and combined effects of creatine and turmeric on muscle and non-muscle (fibroblast) cells. The differential effect was observed on both cell line in the presence of creatine alone and turmeric alone treatment. When creatine and turmeric were tested separately, creatine increases the proliferation rate of muscle cells and decreases proliferation rate of non-muscle cells at tested concentrations (3.25µg/mL, 32.5µg/mL, and 325µg/mL). On the other hand, turmeric increases the proliferation rate of non-muscle cells compared to muscle cells at tested concentrations (4.62µg/mL, 23.1µg/mL, and 46.2µg/mL). Non-muscle cells showed a decreased proliferation with creatine (325µg/mL) and increased proliferation with turmeric (46.2µg/mL) at maximum tested concentrations. Hence, for testing their combined effect on both cell lines higher concentrations (650µg/mL and 925µg/mL) were used. The combined concentrations of creatine and turmeric at 650µg/mL and 925µg/mL did not show a significant effect on muscle cells. However, the same concentrations increased the proliferation of non-muscle (fibroblast) cells compared to muscle cells. Although creatine alone or turmeric by itself was found to be more effective on the proliferation of non-muscle cells than combining both of them together. The results of this study suggest that creatine and turmeric supplementation together may not be beneficial for post-workout recovery. However, both of them together may be used in skin cosmetics formulation to improve skin cells.","PeriodicalId":15033,"journal":{"name":"Journal of Applied Biotechnology & Bioengineering","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76676676","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}

Recently, an increasing body of research has been evaluating the potential of NNS for alternative uses in healthcare and medicine. Some of these sweeteners, such as stevioside, have been implicated as being anti-hypertensive, anti-carcinogenic, and anti-inflammatory in several contexts. To examine the potential of NNS such as stevioside as an anti-carcinogenic agent, cellular behavior of HFF-1 human foreskin fibroblasts (ATCC SCRC-1041) & COLO-829 human melanoma fibroblasts (ATCC CRL-1974) was observed in the presence of sucrose, sucralose, and stevioside on collagen. This study examined the impact of NNS on initial adhesion, cellular proliferation, and integrin expression on healthy and cancerous fibroblast cell lines. The results indicate that 5 mg/mL stevioside caused more than 2-fold decrease in the initial adhesion of healthy cells but caused more than 4-fold increase in the initial adhesion of cancerous cells. In terms of proliferation, stevioside at 5 mg/mL caused a 13-fold decrease in cancer cell proliferation, proportional to concentration, but a 1.5-fold increase in proliferation for healthy cells.","PeriodicalId":15033,"journal":{"name":"Journal of Applied Biotechnology & Bioengineering","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85316457","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}

Objective: Determine factors associated with the prevalence of dyslipidemia among climacteric women treated in a reference clinic in southern Brazil. Method: Cross-sectional study with 550 women aged 40–65 years treated in a clinic specialized in climacteric therapies and gynecologic surgeries. A precoded and pretested standardized survey with questions about socioeconomic, demographic, behavioral and reproductive features was applied. Laboratory tests needed to define lipid profiles were the analysis of HDL cholesterol, total cholesterol, and triglycerides. Multivariate analysis (p<0.05) was used in the evaluation of data. Results: 550 climacteric women were evaluated. Elevated prevalence of dyslipidemia (83.8%) was found. The group presenting the largest number of dyslipidemic women was the group aged 56–65 years (92.5%). There was no significant association between the occurrence of dyslipidemia and menopausal state. Multivariate analysis revealed that dyslipidemias were 11% more prevalent in women aged 56–65 years (RP 1.11; CI95% 1.01 to 1.21 p=0.03) and 16% more frequent among women with three or more gestational periods (p=0.04). The prevalence of dyslipidemia was also higher among obese women than among the eutrophic ones, however, the significance level remained in a boundary zone (PR 1.12; CI95% 1.00 to 1.26 p=0.06). Conclusion: A higher prevalence of dyslipidemia was found among women with multiple pregnancies, something that may be linked to hormonal and metabolic issues, as well as dietary issues during pregnancy. The menopausal state was not associated with the occurrence of dyslipidemia in this study. Possibly, the aging process and its metabolic changes —more than the menopausal state itself— is the main factor associated with dyslipidemia during the climacteric years","PeriodicalId":15033,"journal":{"name":"Journal of Applied Biotechnology & Bioengineering","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80189678","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}
