It is the application of engineering principles to design and construct new bio-based biologicals, devices and systems that exhibit functions not present in nature or to redesign the existing systems to perform specific tasks. Synthetic biology varies from other disciplines including system biology, biotechnology and genetic engineering. For instance, while system biology focuses on obtaining a quantitative understanding of the naturally existing biology systems, the synthetic biology focuses on engineering, designing, and synthesis of new novel biological functions utilizing the biological information drawn from systems biology analysis. SB utilizes computer algorithms to alter genetic sequence before synthesizing them in the laboratory. Moreover, SB employed gene shuffling and refactoring tools that may alter thousands of genetic elements of an organism at once. In the present article, we aim to discuss the basic approaches of synthetic biology. Furthermore, the application of synthetic biology on biomedical science, drug discovery development, bioenergy and agriculture will also be discussed. Finally the challenges facing the researchers in the field of synthetic biology such as those technical, ethical and safety will be also highlighted.","PeriodicalId":371643,"journal":{"name":"Abasyn Journal Life Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129596245","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}

{"title":"Antifungal resistance modulation of Aspergillus fumigatus isolates from brooder pneumonia affected birds by Eucalyptus globulus extracts","authors":"","doi":"10.34091/ajls.3.2.14","DOIUrl":"https://doi.org/10.34091/ajls.3.2.14","url":null,"abstract":"Brooder pneumonia is a common respiratory problem during brooding period of poultry. It is most frequently caused by Aspergillus fumigatus. Use of azole drugs for treatment and prophylaxis results in resistance. The aim of this study was to determine whether the phytochemicals of Eucalyptus globulus are modulating resistance in Aspergillus fumigatus. Lung samples n = 50 of dead broiler chicks were collected from different farms of Lahore. Out of 50 lung samples 28 % (14) were considered positive for Aspergillus fumigatus after observing their macroscopic, microscopic characteristics and by performing PCR by amplifying ITS1-ITS4 gene (597 base pairs) and RodA gene (313 base pairs). Kirby-Bauer disc diffusion test was performed 14 isolates (100 %) were resistant towards both Fluconazole and Ketoconazole whereas 11 (78.57 %) were resistant towards Itraconazole. Eucalyptus globulus leaves were collected, and these were identified. Three solvent extracts were prepared. Maximum yield was of ethanolic extract. Antifungal activity was evaluated by agar well diffusion method. Highest antifungal activity was shown by Eucalyptus globulus Ethanol followed by chloroform and hexane extract showed no activity against any isolate then minimum inhibitory concentration of plant extracts that previously showed antifungal activity against isolates were evaluated by broth microdilution method. Modulation effect was checked by combining antifungal drug one by one with subinhibitory concentration of plant extract evaluated previously by broth microdilution method. 5 isolates were subjected into this experiment which are all sensitive towards Eucalyptus globulus ethanol and chloroform extracts tested previously in agar well diffusion test and MIC values were also evaluated. It was concluded that when Itraconazole was combined with E. globulus Ethanol extract then resistance was modified. Data of modulation was analyzed by One-way ANOVA and it reported P value of <0.05. It was synergistic inhibitory effect when Itraconazole was combined with Eucalyptus globulus Ethanol extract.","PeriodicalId":371643,"journal":{"name":"Abasyn Journal Life Sciences","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123180343","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}

It is a kind of viral hepatitis. It has naked nucleocapsid virus with a single stranded, positive polarity RNA. It is devoid of virion polymerase and has a single serotype. Transmission is via fecal–oral route. In contrast to Hepatitis B virus and Hepatitis C virus, blood borne transmission of HAV is infrequent because viremia is short-term and of low titer. Mostly instances, have few or no signs, specifically in younger ones. The virus replicates in the gastrointestinal tract and then spreads to the liver during a short-term viremic period. HAV is not cytopathic for the hepatocyte. Hepatocellular injury is triggered by immune attack by the cytotoxic T cells. The time among the infection and signs, in patients that progress them, is among two and six weeks. When the signs occur, they commonly last 8 weeks and might encompass nausea, vomiting, diarrhea, jaundice, pain in abdomen and fever. Around 10 to 15 percent of patients undergo a recurrence of signs at some stage in the six months after the preliminary infection. Acute liver failure may also seldom occur, with this being extra regular in elderly. No antiviral medication is available. The most suitable test to diagnose acute infection is IgM antibody. Isolation of the virus from clinical samples is not done. Vaccine consists of killed virus. Administration of immune globulin in the course of the incubation can alleviate the disease.","PeriodicalId":371643,"journal":{"name":"Abasyn Journal Life Sciences","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126515527","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}

Therefore, the identification of functional and structural polymorphisms in CEBPA is important to study and discover therapeutics targets and potential malfunctioning. For this purpose, several bioinformatics tools were used for the identification of disease-associated nsSNPs, which might be vital for the structure and function of CEBPA, making them extremely important. In silico tools used in this study included SIFT, PROVEAN, PolyPhen2, SNP&GO and PhD-SNP, followed by ConSurf and I-Mutant. Protein 3D modelling was carried out using I-TASSER and MODELLER v9.22, while GeneMANIA and string were used for the prediction of gene-gene interaction in this regard. From our study, we found that the L345P, R333C, R339Q, V328G, R327W, L317Q, N292S, E284A, R156W, Y108N and F82L mutations were the most crucial SNPs. Additionally, the gene-gene interaction showed the genes having correlation with CEBPA’s co-expressions and importance in several pathways. In future, these 11 mutations should be investigated while studying diseases related to CEBPA, especially for AML. Being the first of its kind, future perspectives are proposed in this study, which will help in precision medicine. Animal models are of great significance in finding out CEBPA effects in disease.","PeriodicalId":371643,"journal":{"name":"Abasyn Journal Life Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131291710","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}
