They have shown potential in disease treatment. In this study, the activities of Arachis hypogaea , Dolichos biflorus , Erythrina crista-galli , and Glycine max lectins were evaluated (using hemagglutination assays), compared, and their biological activities were examined. Blood-group specificities along with the effects of temperature and pH on lectin activities were also evaluated. The lectins‟ antibacterial and antifungal properties were tested via a disc diffusion assays. An HIV-reverse transcriptase (HIV-RT) colorimetric assay was performed to explore the antiviral properties. A . hypogaea , G. max , and E. crista-galli lectins were observed to be non-blood group specific, while D. biflorus lectin only agglutinated sheep erythrocytes. Using agglutination assay against rabbit erythrocytes, lectin activity of G. max was observed to be significantly higher than those of A. hypogaea and E. crista-galli at all pH levels, 5.2, 7.2, and 9.2. Lectin activity of G. max , A. hypogaea and E. crista-galli decreased as temperature increased from 0°C to 100°C. Although all four leguminous lectins were found to be devoid of antibacterial and antifungal activity, each lectin showed HIV-RT inhibition activity, with G. max having had the highest mean HIV-RT percent inhibition.","PeriodicalId":352493,"journal":{"name":"American International Journal of Biology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124650196","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}

The relationship between prey and predator is shaped around the risk of predation. A non-consumptive impact of predators on their prey seems to be more extensive and diverse, with significant consequences for community structure and function of the ecosystem. Predators have a strong direct and indirect effect on ecological communities by intimidating their prey. Ecological context including habitat structure and identity of species have influenced the strength and nature of nonconsumptive effects and hence it may alter the outcome of intimidation of predator. Further, this study uses secondary data collection methods. The relationship between predation fear and aging behavior of prey, reproduction behavior of prey and territorial defense strategies of prey are detailed in the prior literature review. Since a wide range of wildlife is under existential crisis especially the predators, there is a need to understand the predator-prey relation. In the future, this work can be detailed by collecting the primary data source through a quantitative approach among various investigators.","PeriodicalId":352493,"journal":{"name":"American International Journal of Biology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123764977","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 work aims to show the disproportionate elevation of serum ferritin levels in chronic kidney failure patients. This is a six-month retrospective study. We evaluated iron metabolism, C reactive protein (CRP), and hemogram determination in 2 groups of patients. The first group consisted of 200 chronic kidney failure patients with anemia, the second group consisted of 100 anemic patients with normal kidney function, no inflammation, infection or tumoral disease. The average age in the first group was 60.2±14.08. The mean ferritin level was 385.25ng/mL ±360.52. Serum ferritin level was ≤500 ng/mL in 119 patients, between 500 and 1000 ng/mL in 47 patients, and greater or equal to 1000ng/mL in 34 patients. As for the second group, the mean ferritin level was 28.20ng/mL ±72.13. The prevalence of iron overload was significant in group 1(40%). However, no case of overload was reported in the 2nd group. Through the results of this work, we deduced that there is a statistically significant correlation between chronic kidney failure and serum ferritin increase.","PeriodicalId":352493,"journal":{"name":"American International Journal of Biology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127435858","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}

We described clinical course of male newborn, second in order, with enormous concentration of ammonia, 4000 μmol/l. The first child died in early neonatal period with diagnosis of “severe neonatal sepsis”. Laboratory finding showed no metabolic acidosis, abnormal plasma amino acids, absence of citrulline and increased urinary orotic acid. Despite aggressive treatment including he modyafiltration, hydration with dextrose and salt, dietary regime without proteins, ammonia scavengers as sodium benzoate and arginine repletion, newborn developed severe encephalopathy, multiorgan failure and died on the sixth day following birth. Due to short and catastrophic course of UCD in neonatal period, there is a high possibility of misdiagnosis, especially differential to neonatal sepsis and prompt ammonia measurement is the crucial step. Identifying specific UCD is not available in many countries with limited resources. Laboratory parameters will guide the diagnostic workup of a patient with hyperammonemia for which a specific diagnosis is yet unclear. Since the molecular genetic testing is the method of first choice, in order to confirm the diagnosis it is necessary to preserve frozen fibroblasts and provide genetic counseling.","PeriodicalId":352493,"journal":{"name":"American International Journal of Biology","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115769478","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}
