    Presence of different bacterial species in thermal sources and novelty in their industrial enzyme productions

    Albayrak, Seyda; Genc, Berna; Ozkan, Hakan; Taskin, Mesut; Adiguzel, Ahmet

    In this study, one hundred and thirty isolates were isolated from water and sludge samples taken from hot springs located in different regions of Turkey. Among them, eleven isolates were chosen according to conventional (morphological, physiological and biochemical tests) and molecular methods (rep-PCR and 16S rRNA sequencing). These bacteria were then tested for their capability to produce valuable enzymes. As a result; species belonging to Bacillus, Anoxybacillus, Aeribacillus, Enterococcus, Exiguobacterium and Paenibacillus were identified. Test strains were found to have optimum reproductive potential at pH 5.0-9.0 and 15-65°C, usually at a concentration of 1.0-10.0% (w/v) NaCl. In addition, all thermotolerant bacteria were Gram, endospore (except E. profundum), catalase and oxidase (except E. faecium and E. profundum) positive, and rod-shaped (except E. faecium). It was observed that all isolates had a 99% similarity percentage as a result of 16S rRNA sequence analysis. All of the isolates were capable of producing industrially important enzymes moreover, eight of them could produce at least two of these enzymes. Test strains had high potential of industrial enzyme production, and the enzymes from these thermo-tolerant isolates will be widely used in biotechnological processes.

    Automation in the Mining Industry: Review of Technology, Systems, Human Factors, and Political Risk

    Rogers, W. Pratt; Kahraman, M. Mustafa; Drews, Frank A.; Powell, Kody; Haight, Joel M.; Wang, Yaxue; Baxla, Kritika; Sobalkar, Mohit

    In the opinion of these authors, technology alone can never give an organization an edge over competitors or provide an industry step change. However, history has shown that technology applied with correct logistics and strategy makes a significant difference. Never has the minerals industry faced such daunting challenges and been in such need of a step change. Application of autonomous systems has been steadily increasing in the minerals industry. Automation technology has changed the mining value chain from exploration to mineral processing and refining. The future state will only see additional in-roads of automation into more processes and the whole system design. To better understand the near-future potential of automation, it is useful to explore and review the current state of automation in minerals development. A review of the state of automation research is given. The review will consider three critical areas: automation technology, system’s engineering and management processes around automation, and the role of human factors engineering in automated and semi-automated systems. The review ends with a discussion on the social and political risks of automation in terms of shared value and sustainable development.

    Exploring the value of using data: a case study of continuous improvement through data warehousing

    Rogers, W. Pratt; Kahraman, M. Mustafa; Dessureault, Sean

    The mining industry is adapting data-rich technology. Data management processes and infrastructure require additional investment which, can be difficult to justify. A valuation model for data management infrastructure would necessitate modelling the ‘use’ of data and quantifying the value and the likelihood of success of improvement initiatives. A model is presented which can assess the impacts of a data-driven initiative. The initiatives are shown to be the foundation of improved shift coordination resulting in significant and sustained operational improvements. This paper aims to illustrate the value of using data from source systems in mining operations.

    In response to the 2013 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This study covers a highest-luminosity high-energy lepton collider (FCC-ee) and an energy-frontier hadron collider (FCC-hh), which could, successively, be installed in the same 100 km tunnel. The scientific capabilities of the integrated FCC programme would serve the worldwide community throughout the 21st century. The FCC study also investigates an LHC energy upgrade, using FCC-hh technology. This document constitutes the second volume of the FCC Conceptual Design Report, devoted to the electron-positron collider FCC-ee. After summarizing the physics discovery opportunities, it presents the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan. FCC-ee can be built with today's technology. Most of the FCC-ee infrastructure could be reused for FCC-hh. Combining concepts from past and present lepton colliders and adding a few novel elements, the FCC-ee design promises outstandingly high luminosity. This will make the FCC-ee a unique precision instrument to study the heaviest known particles (Z, W and H bosons and the top quark), offering great direct and indirect sensitivity to new physics.

    Prostate volume effect on Gleason score upgrading in active surveillance appropriate patients

    Çamur, Emre; Coskun, Alper; Kavukoglu, Ovunc; Can, Utku; Kara, Onder; Çamur, Arzu Develi; Sarica, Kemal; Narter, Kamil Fehmi

    Introduction: Gleason Score (GS) upgrading rates in the literature are reported to be around 33-45%. The relationship between prostate volume and GS upgrading should be defined, aiming to reduce upgrading rates in patients with low risk groups who are eligible for active surveillance (AS) or minimally invasive treatment, by varying biopsy cores, or lengths of cores according to prostate volumes. In this regard, the aim of our study was to establish the relationship between prostate volume and GS upgrading. Materials and methods: We retrospectively analyzed the medical records of 78 patients, who were appropriate for AS between 2011-2016 at our hospital. Inclusion criteria were patient age under 65 years, PSA level under 10 ng/ml, GS (3 + 3) or (3 + 4), and 3 or less positive cores, clinical stages <= T2. GS increase in radical prostatectomy specimen was considered as 'upgrading' and in addition, score reported by biopsy as 3 + 4 but in surgical specimen as 4 + 3 were also considered as 'upgrading'. The effect of prostate volume on Gleason grade upgrading was examined by calculating upgrading rates separately for patients with prostate volume 30 ml or less, those with 30 to 60 ml, and those over 60 ml. Results: As a result of the analysis of the data, upgrading was seen in 35 (44.8%) of 78 patients included in the study. In the cohort mean prostate volume was 49.8 (+/- 26.3) ml. Twenty-two patients (28.2%) had prostate volume 30 ml or less, 34 (43.6%) 30 to 60 ml, and 22 (28.2%) 60 ml or more. The patients were divided into two groups as those with and without GS upgrading. Between the groups prostate volume and prostate volume range (0-30/31-60/> 60) were not significantly different (p value > 0.05). Conclusions: Gleason grade upgrading causes patients to be classified in a lower risk group than they actually are, and may lead to inappropriate treatment. This condition has a direct effect on the decision of active surveillance. Therefore, it is important to define the factors that can predict GS upgrading in active surveillance appropriate patients. In this study, we found that prostate volume has no significant effect on upgrading in active surveillance appropriate patients.

    Anticholinergic, antidiabetic and antioxidant activities of cinnamon (cinnamomum verum) bark extracts: polyphenol contents analysis by LC-MS/MS

    Gulcin, Ilhami; Kaya, Ruya; Goren, Ahmet C.; Akincioglu, Hulya; Topal, Meryem; Bingol, Zeynebe; Cakmak, Kader Cetin; Sarikaya, Sevim B. Ozturk; Durmaz, Lokman; Alwasel, Saleh

    Ethanolic (EEC) and aqueous (WEC) extracts of cinnamon (Cinnamomum verum) were evaluated for their antioxidant profiles by eight distinguished bioanalytical antioxidant methods. Their inhibitory effects were tested against some enzymes including acetylcholinesterase, butyrylcholinesterase, alpha-glycosidase and alpha-amylase, which linked to different diseases. Additionally, the antioxidant properties were determined and polyphenolic compositions of the both extracts were evaluated by LC-MS/MS analysis. According to the LC-MS/MS experiments, thirteen compounds were found in WEC and EEC. Also, p-hydroxybenzoic acid (321.1 mg/kg extract), p-coumaric acid (291.4 mg/kg extract), and pyrogallol (142.4 mg/kg extract) were found to be the most abundant ingredients in the WEC. On the other hand, pyrogallol (264.3 mg/kg extract), ferulic acid (224.7 mg/kg extract) and p-coumaric acid (170.2 mg/kg extract) were found as the most plentiful chemicals in the EEC. For the estimation of the antioxidant capacities of the both extracts (WEC and EEC), DPPH center dot and ABTS(center dot+) scavenging activities, as well as Fe3+-Fe2+, and Cu2+-Cu+ reducing assays were studied. The IC50 values of the WEC and EEC indicated that they were potent effective DPPH center dot (21. 25 and 15.71 mu g/mL) and ABTS(center dot+) (6.52 and 5.79 mu g/mL) scavengers, as well as AChE (221.33 and 110.26 mu g/mL), BChE (461.69 and 94.93 mu g/mL), alpha-glycosidase (206.86 and 220.00 mu g/mL) and alpha-amylase (189.86 and 200.86 mu g/mL) inhibitors. As a conclusion, both EEC and WEC had rich phenolic contents and demonstrated effective anticholinergic, antidiabetic and antioxidant effects.

    A novel niosome formulation for encapsulation of anthocyanins and modelling intestinal transport

    Fidan-Yardimci, Melike; Akay, Seref; Sharifi, Fatemeh; Sevimli-Gur, Canan; Ongen, Gaye; Yesil-Celiktas, Ozlem

    The bioavailability of drugs can be improved by regulating the structural properties, particularly lipoid systems, such as niosomes, can increase cellular uptake. Herein, we optimized double emulsion and niosomal formulations for encapsulating anthocyanin-rich black carrot extract. Nanoparticles obtained by selected formulation were characterized in terms of morphology, particle size, drug encapsulation efficiency, in vitro release and cytotoxicity. The optimum conditions for niosomal formulation were elicited as 30 mg of cholesterol, 150 mg of Tween 20 and feeding time of 1 min at a stirring rate of 900 rpm yielding the lowest average particle size of 130 nm. In vitro release data showed the majority of the encapsulated anthocyanins were released at the end of 10 h. A mathematical model was developed to estimate the absorption of anthocyanins released from niosomes and cytotoxicity was assessed against neuroblastoma. Overall, these findings suggest that niosomal vesicles might be suitable delivery systems for anthocyanins.

    Hendek, Muge; Bektaş, Müberra

    The most of plant foods, nuts and cereals contain antinutrient compounds. They reduce to mineralbioavailability and protein absorption of foods thanks to their chelating properties. They causes tomicronutrient malnutrition and mineral deficiencies. The micronutrient malnutrition is a widespreadglobal health problem not only in developing but also in many countries. Increasing micronutrientintake in food through food processing based approaches is a sustainable method of prevention ofmicronutrient malnutrition which should be achieved through food diversification. There are traditionaland technological methods that provide reducing of antinutrient compounds.The pretreatmentand processing techniques as soaking, fermentation, germination, debranning, and autoclaving areeven traditional methods which use generally in consumption of foods.Removing antinutrients, thebioavailability of some cation (Ca, Fe and Zn) and the absorption of proteins make to increase andconsequently nutrition value of food increase. It is possible to reduce antinutrient factors by usingdomestic or industrial basic food processing techniques alone or in combination.This review focusedon various methods to reduce antinutrients in food such as phytic acid, tannin, and oxalate in foodgrain to improve nutritional quality of foods.

    During the 1929 Economic Crisis, prices of agricultural products decreased muchmore than industrial products. Turkey, as an agricultural product exporter could not affordits importation under these new conditions. For the financial structure of Turkey, selfsufficiencywas seen as the most convenient solution. In this period, the Turkish governmentaimed at importing substitution in sugar production. But for achieving this, Turkey neededsome additional investments. For the capital needs of these investments, governmentprimarily evaluated foreign contribution. But Turkish banks provided necessary capital tosugar industry, with the leadership of İş Bankası. German and Czechoslovak contributionalso supplied machinery and technical assistance to Turkish sugar industry. Governmentdeeply investigated possible investment places, to reach the most appropriate conditions.At last, Turkey founded two new sugar factories with their own financial sources in 1933and 1934. Eskişehir Sugar Factory was the third factory in Turkey and Turhal Sugar Factorybecame fourth investment in this field. Government unified the whole sugar production ofTurkey in 1935, in order to reduce production costs. From this date, Turkey experienced rapidexpansion in both beet agriculture and sugar industry. In this article, the state centered sugarproduction investments were evaluated under the different financial conditions of the 1929Economic Crisis. For the time period, subject would be investigated up to the early 1940’s.

    Antidiabetic Potential: Effect of Resorcinol on α-Glycosidase and α-Amylase Enzymes

    Topal, Fevzi

    The vast majority of the carbohydrates in the biomolecule class are formed by photosynthesis using sunlight. One of the important enzymes in this class is α-glycosidase. This enzyme converts complex carbohydrates to monosaccharides. On the other hand, another important enzyme species is the α-amylase enzyme. Which directly related to starch. Starch is a type of polymer formed by the oxygen binding of glucose units to each other at the C1 position with glycosidic bonds. α-Amylase is an enzyme that catalyzes the hydrolysis of glycosidic bonds in starch, and this enzyme is purified from a wide variety of animals, plants, and microorganisms. Resorcinol, a phenol derivative, is an important organic chemical substance in the production of textile, medicine, hair dye, plastic and agricultural products of many industrial materials. Resorcinol, a phenol derivative, is present as white crystals, and resorcinol consists of two hydroxyl molecules attached to the benzene ring, and also was defined as α-glycosidase and α-amylase inhibitor to detect antidiabetic properties. Resorcinol was used as 𝛼-glycosidase and 𝛼-amylase inhibitor. Accordingly, IC50 values of α-amylase and α-glycosidase were calculated as 1.34 μM and 77.00 nM, respectively. On the other hand, Ki value for α-glycosidase was found as 30.16 nM. It has been observed that α-amylase and α-glycosidase enzymes can inhibit by resorcinol compound. It has the properties of inhibiting carbohydrate absorption by inhibiting α-glycosidase enzymes in the small intestine. For both metabolic enzymes, resorcinol may be preferred as an inhibitor. In this case, resorcinol may be used as an inhibitor against to healty problems like Diabetes mellitus and antiobesity.
