The effect of different temperatures, inoculum size, glucose concentration, yeast extract concentration, pH, and culture media on the β-glucan production from saccharomyces cerevisiae was studied. In addition, the dry weight of biomass containing β-glucan was measured. The results showed that the optimum conditions for β-glucan production were when the cells were grown at 30 ºc for 48 hours and pH = 7 with 10 % inoculum size, 2% glucose, and 0.1% yeast extract. Furthermore, the best culture medium for β-glucan production was yeast extract-glucose medium with a dry weight of glucan 2.5mg/5ml. In addition, this study aimed to determine the best method for β-glucan extraction with acceptable purity and concentration. Β-glucan was extracted using two methods autolysis and alkali-acids extraction. The dried and weighed crude β-glucan was 6 gm/l, and 8 gm/l for autolysis of yeast cells, and alkali-acids extraction, respectively. The analysis of glucan by FT-IR and HPLC showed that the method of extraction by autolysis of yeast cells was successful to obtain β-glucan without the presence of the α-glucan with a concentration of β-glucan 10.8mg/gm, while in the extraction by alkali-acid were obtained mixtures of α-glucan and β-glucan with the concentration of β-glucan 7.4 mg/gm. The current study revealed that the optimum conditions of β-glucan production and the best culture medium for β-glucan production was yeast extract-glucose medium and the best method for β-glucan extraction was autolysis extraction.","PeriodicalId":7867,"journal":{"name":"Al-Mustansiriyah Journal of Science","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87178622","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}

These packages have non-real-time interfaces that are hard to use. ChatGPT is a chatbot-specific GPT-3 language paradigm. It lets developers create chatbots that respond intelligently to natural language user input, creating a more engaging user experience. This article shows that ChatGPT, Python, and API wrapper technology may be used to develop a smart chatbot. We show how to use the OpenAI API library to add ChatGPT to Python programs. This makes it easier for developers to make chatbots that sound and act more like real people when they talk. Our contribution to this field is showing that it is possible to make smart chatbots with ChatGPT and API wrapper technology. To reach this goal, we use a system that combines the OpenAI API with ChatGPT and Python. This gives us valuable information about how to make smart chatbots. The efficiency of the system has been tested many times while applying it to different environments, and the results are satisfactory.","PeriodicalId":7867,"journal":{"name":"Al-Mustansiriyah Journal of Science","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84662645","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}

A field emission scanning electron microscope, x-ray diffractometer, energy dispersive x-ray, and UV-VIS spectroscopy were used to examine the morphology and crystallinity of a CuO film. The synthesized CuO film displays a monoclinic phase with average crystallite sizes of around (18–25) nm. CuO is composed of NRs aggregating together to construct flower and flower bud-like shape structures with a diameter between (20-80) nm and a thickness of the CuO film is about (158.5-285.7) nm. The energy gap of CuO NRs was 2.55 eV. The I-V characteristics of the biosensors were measured and evaluated at various glucose concentrations to determine their sensitivity. The electrocatalytic performance of the CuO for the detection of glucose was outstanding. With a very low limit of detection (LOD) of 0.45 μM and a sensitivity of 799 µA cm-2 Mm-1, the electrode attained a wide linear range from 0.5 to 2 mM. This result highlights the sensor's tremendous potential as a high-performance non-enzymatic glucose sensor that makes use of an original, cost-effective, and straightforward sensor design.\u0000 ","PeriodicalId":7867,"journal":{"name":"Al-Mustansiriyah Journal of Science","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89504027","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 happens when \"plaque,\" or cholesterol or other fatty deposits that accumulate on the inner wall of the artery, narrows or blocks the arteries that deliver blood to the heart. Over time, chest pain might develop as a result of the reduction in blood flow to the heart caused by this plaque accumulation. The study was designed to find if Arginase acts as a biomarker for diagnosing Coronary Artery Disease (CAD). A total of 90 individual samples were included in the present study, the control group consist of 40 healthy individual samples, while the CAD patients were 50 individual samples. Some biochemical parameters such as fasting blood glucose (FBG), troponin I(TnI), high sensitivity C-reactive protein (hs-CRP), lipid profile, lactate dehydrogenase (LDH), and Arginase activity were analyzed. The results of the current study showed no significant differences in the average age of patients (67.00±6.78) when compared with the control group (61.10±6.46), P>0.05. A significant increase Was found in the FBI level, cholesterol, triglycerides, very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), TnI, hs-CRP, LDH, and Arginase activity in the patient's group when compared with the control group. While significant decrease (P<0.05) was revealed in the high-density lipoprotein (HDL) level in CAD patients in comparison to the control group. Also, there was a positive significant correlation between Arginase activity with each age and FBG. As for the ROC operator curve for Arginase, it was found that the area under the curve (AUC) was 0.953 with a sensitivity of 90%, and specificity of 95%. The results in the present study indicate a possible use of Arginase as a diagnostic marker for CAD.","PeriodicalId":7867,"journal":{"name":"Al-Mustansiriyah Journal of Science","volume":"114 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77762182","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}
