A Theoretical Approach to Artificial Intelligence in Consumer Behavior

The main purpose of this research is to investigate the effects of artificial intelligence, which has increased its popularity in recent years, on the purchasing behaviors of consumers, which have existed since the first ages, in order to meet their needs. In the study, primarily consumer behaviors are explained. Afterward, a literature search was conducted on the emergence and development of artificial intelligence. Finally, the effects of these two concepts on each other were analyzed

In vivo alterations in glutathione-related processes, lipid peroxidation, and cholinesterase enzyme activities in the liver of diazinon-exposed Oreocbromis niloticus

WOS: 000248505100002PubMed ID: 20020955Although its usage is partially banned in developed countries, organophosphate (OP) pesticide diazinon finds extensive agricultural application in our country (Turkey). This study was conducted to evaluate the effects of diazinon on total glutathione (tGSH), GSH-related enzymes, cholinesterase (ChE) enzyme activities, and lipid peroxidation in the liver of Oreochromis niloticus, a freshwater fish, as a model organism. Fish were exposed to 0.1, 1, and 2 mg/L sublethal concentrations of diazinon for 1, 7, 15, and 30 days. Total GSH levels, GSH-related enzyme and ChE-specific activities, and malondialdehyde (MDA) levels were analyzed using spectrophotometric methods. tGSH levels are decreased at 1 day, while they were increased in the long-term period. GSH-related enzyme activities are affected by diazinon exposure, except glutathione reductase (GR; EC 1.6.2.4). Diazinon displayed an oxidative stress-inducing potential and it increased lipid peroxidation. Similar inhibition levels were observed in acetylcholinesterase (AChE; EC 3.1.1.7) and butyrylcholinesterase (BChE; EC 3.1.1.8.) enzyme activities, and these inhibitions were not dose dependent. ChE inhibition-related oxidative stress was observed using its correlation with elevated tGSH levels and increased glutathione S-transferase (GST; EC 2.5.1.18) enzyme activities; that reflects the diazinon-induced oxidative stress in the liver of O. niloticus. According to the results of the present study, tGSH level and GST-specific activity are suitable for reflecting the toxic effects of diazinon in fish

Fibrous dysplasia as a rare cause of nasolacrimal duct obstruction

Fibrous dysplasia of the paranasal sinuses is mostly asymptomatic, but sometimes may cause signs and symptoms de- pending on its location. We report two cases of maxillary fibrous dysplasia obstructing the lacrimal drainage system as a reason of chronic dacryocystitis, and reviewed the related literature. The first case underwent an endonasal endoscopic approach combined with external dacryocystorhinostomy. He had a patent lacrimal system at one-year follow-up. The le- sion was completely removed via an endonasal endoscopic approach in the second case, wherein the patient was asymp- tomatic of the six-month follow-up period.

Endoscopic Transnasal Transpterygoid Approach For Parasphenoidal Myxoma

The parasphenoidal region is a difficult location to gain access to and contains a lot of vital neurovascular structures that have risk of injury during surgery. The transnasal endoscopic approach for this region has been described in several cadaveric studies in recent years. Herein we present a case of parasphenoidal myxoma, extending to the anteroinferior border of the cavernous sinus in a 48-year-old woman. The tumor was completely removed by the endoscopic transnasal transpterygoid approach. No postoperative complication was seen. The endoscopic transnasal transpterygoid approach may be a good alternative to external approaches in selective skull base tumors

The Effect of Vermiculite on Flame Retardancy, Physical and Mechanical Properties of Wood Plastic Composites

The effect of expanded vermiculite (e-VMT) was evaluated relative to the physical, mechanical, and flame retardancy performance of flat-pressed wood plastic composites (WPCs). Various contents of e-VMT (2.5, 5, 7.5, 10, 15%) were added instead of wood flour (WF) to the matrix. Due to the hydrophilic nature of the WF, water absorption (WA) and thickness swelling (TS) of WPCs increased as compared to neat polymer-based panels. Meanwhile, e-VMT incorporation limited the WA and TS values. As expected, the lowest WA and TS values were obtained from the highest e-VMT-reinforced WPCs. The addition of e-VMT was also found to enhance the mechanical properties of WPCs. As the e-VMT content increased and the WF content decreased, there was an improvement in flexural strength, modulus of elasticity (MOE), and tensile strength. Compared to the neat polymer panels, the MOE of WPCs increased by up to 77%. Additionally, the flame retardancy performance of WPCs improved with e-VMT reinforcement, with limiting oxygen index (LOI) values increasing up to 24%. Scanning electron microscopy (SEM) images also demonstrated the favorable integration of e-VMT with matrix, thereby improving the mechanical properties. The inconsistency between WF and polymer was also well-observed, highlighting the tendency of WF to interact easily with water

Research on Fatty Acids, ?-tocopherol and Total Pigment Content of the Ulva spp. (Sinop-Turkey, Black Sea)

Deniz yosunları yüksek miktarda protein, yağ asitleri ve mineral maddeler içerir. Makro-alglerin biyokimyasal içerikleri tür, ışık, sıcaklık v.b. koşullara bağlı olarak değişir. Tuzluluk ve sıcaklık koşullarına bağlı olarak Karadeniz, makro-algler bakımından yüksek tür çeşitliliğine sahiptir. Bu çalışmada Karadeniz'in Sinop kıyılarından toplanan Ulva spp. 60C etüvde kurutuldu, toz haline getirildi ve analizler yapılıncaya kadar 20C'de muhafaza edildi. Örneklerdeki pigmentler (klorofil a ve toplam karotenoyit) spektrofotometrik yöntem ile analiz edildi, yağ asitleri Varian GC kullanılarak belirlendi ve ?-tokoferol tespiti için Jasco HPLC kullanıldı. Örneklerde toplam doymuş yağ asitleri (SAT) % 37.2, toplam çoklu doymamış yağ asitleri (PUFA) %32.0, toplam tekli doymamış yağ asitleri (MUFA) % 23,2 olarak tayin edildi. PUFA grubundan 18:3(n-3) % 5.4, 18:3(n-6) % 1.6, 18:4 (n-3) % 6.5 ve 20:5 (n-3) % 4.4 gibi yağ asitlerinin yüksek değerlerde olduğu tespit edildi. Ulva spp.'de ?-tokoferol değeri 9.1 0.5 µg g-1 kuru ağırlık (dw) olarak tespit edildi. Toplam karoten ve toplam klorofil a düzeyleri ise sırasıyla 311.0 0.3 µg g-1 dw ve 706.8 0.7 µg g-1 dw olarak saptandı. Makro-alg türleri ve bunlar arasında Ulva spp. Türk sularında en yaygın dağılıma sahip ve yüksek biyomaslara ulaşan bir Chlorophyceae üyesidir. Yüksek düzeyde pigment, yağ asidi ve vitamin değerlerine sahip olan bu türün olası tüketim yollarının aranması, Türk sularının bu değerli biyolojik kaynağının çok daha etkin bir şekilde kullanılmasını sağlayacaktırMarine algae contain large amounts of protein, fatty acids and minerals. Biochemical composition of macro algae depends on the species, on conditions like light, temperature and so on. Black Sea has a high variety of species with respect to macro-algae because of salinity and temperature conditions. In this study, Ulva spp. which was collected from Black Sea on the coast of Sinop was dried in an oven at 60C, grinded as a powder and kept at 20C until analyses were carried out. Pigments (chlorophyl a and total carotenoid) of samples were analysed with spectrophotometric method, fatty acids were analysed using Varian GC, and HPLC was used for the estimation of ?- tocopherol. Total saturated fatty acids (SAT) were determined to be 37.2 %, total polyunsaturated fatty acids (PUFA) to be 32.0 %, and total monounsaturated fatty acids (MUFA) were determined to be 23.2 %. Within the PUFAs, fatty acids such as; 18:3(n-3) 5.4 %, 18:3(n-6) 1.6 %, 18:4(n-3) 6.5 % and 20:5(n-3) 4.7 % exhibited high values. ?-tocopherol value for Ulva spp. was measured as 9,1 0,5 µg g-1 dw. Total carotenoid and total chlorophyl a levels were measured as 311.0 0.3 µg g-1 dw and 706.8 0.7 µg g-1 dw, respectively. Macro-algae species, and among them Ulva spp., are a member of Chlorophyceae which have the highest distribution in Turkish waters and which attain high biomass. Research into possible ways of use for this species which has high levels of fatty acid, vitamin and pigment will bring about more effective use of this biological source of Turkish waters
