Özgür Tarık Şen | Murat Durmuş | Nazan Koluman
The aim was to examine the structural features and biosecurity practices of sheep farms operating in Niğde province. For this purpose, 75 farms operating in the region were classified according to size (number of animals) and production system (extensive and intensive) and, they were compared in terms of typology and biosafety. In this context, a face-to-face survey was conducted with the owners or authorized persons of the small, medium and large size farms and the data collected from the farms about technical, sanitation-hygiene and health protection were comparatively presented. According to the findings obtained from the study, manure and wastes produced in 24% of farms were seen randomly throwing into the environment, and the differences observed between farms depending on the farm size were found significant (P<0.05). These farms can become a potential source of environmental and odor pollution. In addition, it was determined that disinfection was not applied to a large extent (97.30%) as a preventive measure at farm and shelter entrances (P>0.05). At the end of the study, it has been concluded that the typology and biosafety practices could be an important support for future strategic programs against disease and other factors which affects the production of the Niğde region.

Büşra Altay | Nurgül Arısoy
Rapid population growth, industrial and technological development, and improvement in the social and economical conditions of people have increased their need for socializing, gathering, and relaxing with various recreational activities and mutual communications. The sustainable development of social life has increased the importance of squares as public spaces, which brings the citizens together for cultural, commercial, and political purposes; thus, giving an identity to the city and becoming the focal point of urban life. The selection of an area as a square is based on certain criteria. The decisions regarding the choice of the location and their use as squares must be per the internationally accepted criteria. We studied four squares, namely Mevlana Square with historical background, Hükümet Square, Anıt Square, and Kılıçarslan City Square with a high demand for social events. The squares are considered to be important and comprehensive titles for evaluating their comparative functions under the selection criteria of visuality, functionality, and accessibility. The Analytical Hierarchy Process (AHP) method was used to determine the importance of the selection criteria of squares in a survey with participants for solving the problem and selecting the best square according to these criteria. By performing the AHP analysis, we found that the most preferred square by the participants was the Mevlana Square with a preference rate of 58.68%, and the most preferred criterion was “visuality” with a preference rate of 64.5%. In this study, we aimed to determine the characteristics of a preferable square to improve the existing squares and to contribute to the stages of a new square design, planning, and implementation.

2023
Pelin Toprak | Ayşe Ezgi Ünlü
Shalgam juice is one of the most popular non-alcoholic beverages in Türkiye and also in many countries. The high amount of production, regarding the high amount of consumption leads to an inevitable amount of solid waste. This amount reaches to almost 12 million kg of fermented black carrot annually. The accumulation of this waste causes fatal environmental pollution. The waste of shalgam juice process, fermented black carrot, retains significant amount of valuable components, such as phenolics, flavonoids, and anthocyanins. In this study new generation green solvents, Natural Deep Eutectic Solvents (NADESs) were screened for the extraction of valuable phenolics from fermented black carrot using ultrasound assisted extraction. The NADESs used were selected from four different groups such as acidic, sugar-based, choline chloride-sugar based and polyol-based. According to the results, the members of polyol and choline chloride sugar NADESs showed up. Choline chloride-glycerol (polyol group), extracted the highest total phenol amount (16.04 mg/g) and also provided the highest antioxidant activity (81.77%). On the other hand, NADESs belonging to choline chloride-sugar group were effective for the extraction of flavonoids and monomeric anthocyanins. Namely, choline chloride-fructose-water extract contained 21.45 mg/g of total flavonoids, while choline chloride-sucrose-water extract contained 1680.51 mg/kg of total monomeric anthocyanins. The performances of NADESs tested were found to be higher than that of water and ethanol showing the high yield recovery of valuable phenolics with NADESs. The results exhibited the significance of the components inside the waste. The remaining valuable content could be easily and efficiently extracted using NADESs and these extracts –as a mixture or after purification- can furtherly be used for different purposes in different fields, such as cosmetics, antioxidant preparations, etc, using a zero-cost waste as the input of the processes.

Background: There are several clinical studies examining the health advantages of several single medicinal herbs utilized in traditional blood glucose-lowering treatments. But very few or no studies on herbal formulations were made as Polyherbal for the same goal. As a result, it is now necessary to confirm that patients with hyperglycemia can benefit from such Polyherbal medicines as Dolabi. Methods: This prospective open-label, herbal coded test drug-controlled, randomized trial was conducted at the Munshiganj and Dhaka area in Bangladesh. We enrolled 108 male and 104 female patients of 30-70 years with primary and moderate hyperglycemia. They were recruited from the OPD of an Unani & Ayurvedic hospital in Munshiganj and different Unani clinics in Dhaka, Bangladesh after fulfilling the inclusion criteria. Patients were randomly assigned to receive metformin hydrochloride 500 mg two times daily and 2 tablets of Dolabi two times daily by using a random numbers table with the help of an assistant. Blood samples, height, weight, blood pressure, and personal data were recorded—laboratory results were obtained at the study baseline, after 1.5 months and after 3 months of intervention. Results: In the case of the test drug, results showed a significant decrease in blood glucose level between the baseline and after 3 months, in males, it was from 9.83±1.17 to 7.72±1.06 mg/dL for fasting glucose, from 16.60±2.35 to 8.23±1.17 mg/dL for 2 hours PP glucose, from 9.33±1.17 to 7.45±2.03 percent for HbA1c and for Insulin it reduces from 183.10±27.59 to 168.10±29.59 pmol/ L. The control drug metformin hydrochloride also showed a significant decrease in blood glucose level between baseline and after 3 months, in the case of males it was from 9.99±2.52 to 6.97±1.76 mg/dL for fasting glucose, from 17.43±5.05 to 7.89±2.42 mg/dL for 2 hours PP glucose, from 10.43±2.36 to 6.87±1.18 percent for HbA1c and for Insulin it reduces from 198.75±30.61 to 183.75±30.61p mol/L. In the case of females the test drug showed a significant reduction in fasting glucose, 2 hours PP glucose, HbA1c and Insulin between the baseline and after 3 months, it was from 10.02±1.11 to 7.78±0.93 mg/dL, from 16.88±2.21 to 8.16±1.11 mg/dL, from 9.84±1.04 to 7.45±1.03 percent and from 199.47±30.90 to 173.47±30.90 mg/dL respectively. In the case of females, the control drug showed a significant reduction in fasting glucose, 2 hours PP glucose, HbA1c and Insulin between baseline and after 3 months, it was from 10.18±1.92 to 6.71±1.59 mg/dL, from 18.70±3.88 to 7.60±3.74 mg/dL, from 10.58±1.08 to 6.98±1.08 percent and from 200.00±31.83 to 188.00±31.83 mg/dL respectively. Conclusions: We can infer the following from the present study’s findings: The polyherbal formulation Dolabi is able to reduce the blood glucose level.

Black soldier fly larvae (BSFL; Hermetia illucens L.) is a proven high-cost protein source replacer and could be grown in a range of bio-degradable waste materials where hardly incorporated into broiler diets locally. The present study was aimed to assess the nutritional composition of BSFL, and apparent metabolizable energy (AME) value of BSFL meal provided to broiler chickens. BSFL full-fat meal produced from kitchen waste as a substrate were examined for their proximate composition, minerals and fatty acid profile. Eighty, 21-d old unsexed Cobb-500 broiler chickens (BW±SD: 665.8 ±14.3 g) were assigned randomly into 16 battery cages (04 replicates, five birds/replicate). A maize-soybean meal-based diet was used as the basal diet which was partially substituted by pre-analyzed BSFL meal at the rates of 5%, 10%, and 15% to produce three test diets. Birds were fed in a completely randomized design for 7-d with a 4-d adaptation period. Excreta were collected for three days from day 25 to 28. The results envisaged that the crude protein (CP) and ether extract (EE) contents of the kitchen waste were 12.3%, and 10.5%, respectively. BSFL meal when analyzed had 34.4% CP and 47.3%, EE. The fatty acid (FA) profile of the kitchen waste was more or less similar to that of BSFL‘s meal. The estimated AME of the BSFL full-fat meal fed for broilers was estimated to be 15.7 MJ/kg. The BSFL full-fat meal can be utilized sustainably in feed formulation and has a high potential to replace costlier feed ingredients.

This study aimed to evaluate the effect of incorporating hydrosoluble Opuntia ficus indica seeds extract in unpasteurized prickly pear juice and monitoring its stability. For this purpose, titratable acidity (TA), total soluble solids (TSS), browning index (BI), total phenolic compounds (TPC), total flavonoids (TF), antiradical activity (DPPH), ferric reducing antioxidant power (FRAP) and microbial analysis were monitored for both enriched and controlled juices during different time and temperature storage. Before storage, the enriched juice values were respectively 0.096±0.001%, 14.1±0.01%, 0.756±0.01, 133.3±3.4mgGAE/100ml, 5.58±0.07mgQE/100ml, 95.89±14.27mgGAE/100ml and 59.34±5.52mgGAE/100ml for TA, TSS, BI, TPC, TF, DPPH and FRAP; while 0.16±0%, 14.1 ±0.001%, 1.2±0.01, 88.39±4.2mgGAE/100ml, 3.98±1.003mgQE/100ml, 51.08±14.27 mgGAE/100ml and 50.33±5.16mgGAE/100ml for the control juice. The microbial analysis revealed the absence of microorganisms even the juices were unpasteurized. Moreover, the results revealed that the enrichment attenuated significantly the effect of storage; indeed, the use of the prickly pear seeds extract in combination with the juices can be a good alternative to enhance the shelf life of unpasteurized prickly pear juice, and improve their quality attributes as well as to minimize the unwanted changes in the nutritional and organoleptic properties.

Sunulan çalışmada solunum yolu hastalığı belirtileri gösteren koyunlarda genel fiziksel ve özel klinik muayene bulgularının, tam kan sayımı sonuçlarının ve nazofarengial sürüntü örneklerinin incelenmesi amaçlandı. Çalışmada solunum yolu hastalığı şikâyeti bulunan bir İvesi koyun sürüsünde (n:62) alt solunum yolu hastalığı belirtileri tespit edilen 18 adet dişi koyun kullanıldı. Hasta koyunların yaş kayıtları tutuldu, genel fiziksel muayeneleri gerçekleştirildi. Özel klinik muayene parametrelerinin her biri kendi içinde skorlandı. Hasta koyunlar akciğer oskultasyon skor sonuçlarına göre “Hafif Hasta (n:11)” ve “Orta Hasta (n:7)” şeklinde iki gruba ayrıldı. Hasta hayvanlar da dahil bütün koyunlardan antikoagülantlı ve antikoagülantsız kan örnekleri alındı. Antikoagülantlı kan örneklerinden tam kan sayımı yapıldı. Hasta (n:18) ve sağlıklı (n:6) koyunlardan mikrobiyolojik ve virolojik analizler için steril swap ile nazofarengial sürüntü örnekleri alındı. Kan (n:62) ve nazofarengial sürüntü (n:24) örneklerinden Bovine herpesvirus tip 1, Respiratorik sinsityal virus (RSV), Parainfluenza 3 (PI-3) ve Pestivirus varlığına yönelik analizler gerçekleştirildi. Hafif hasta ve orta hasta koyunlar karşılaştırıldığında, yaş, dakikadaki kalp atım sayısı, klinik durum gözlem skoru, MCH Pg, MCHC g/dL verilerinde gruplar arasında anlamlı farklılık (P<0,05) tespit edildi. Sağlıklı ve hasta olan koyunların nazofaringeal örneklerinde baskın olarak sırasıyla Staphylococcus spp., Streptococcus spp. ve E. coli bakteri türleri izole edildi. Klinik olarak sağlıklı görünen bir koyundan Klebsiella spp. izole edilirken, yalnızca bir hasta koyundan M. haemolytica izole edildi. Sağlıklı görünen bir koyunda serolojik olarak BoHV-1-spesifik antikor tespit edildi. Sonuç olarak saha şartlarında uygulanabilecek en kolay ve en hızlı yöntemler arasında yer alan akciğer oskultasyon bulguları ve nazofarengial sürüntü sonuçları ile muhtemel etiyolojik etken ve hastalık durumu hakkında öngörüde bulunulabilir. Bu sayede ekonomik değere sahip bu hayvanlarda erken muhtemel tanı ile tedaviye başlanarak ekonomik kayıplar azaltılabilir.

Show more [+] Less [-]Determination of Yield and Quality Parameters in Pickling Hot Peppers Grown under Different Water Stress Conditions
2023
Okan Erken | Fatma Çolak Levent
Plants are exposed to various adverse environmental conditions throughout their growth period. In recent years, drought, which has occurred and necessitated different measures, ranks among these adverse conditions. At the same time, plants synthesize certain biochemical compounds in response to the adverse conditions they will encounter. These compounds not only strengthen the immune system but also provide resistance against various diseases, and they tend to increase under adverse environmental conditions that plants will face during cultivation. This study was conducted to determine the changes in yield and some biochemical components in pickling hot peppers (Capsicum Annuum L.) grown under different water stress conditions. Two different levels of water stress (%70 and %30 irrigation) were applied in addition to full irrigation (%100 irrigation). At the end of the research, while a yield of 269.42 g per plant was obtained in the control group (%100 irrigation), 150.14 g and 93.33 g of pickling hot peppers were harvested in each water stress treatment, respectively. Total phenolic compound levels increased with water stress; it was determined to be 0.827 mg-1g in the trial irrigated with full irrigation water, 1.170 mg-1g in plants exposed to mild water stress, and up to 1.536 mg-1g in the trial subjected to severe water stress. In addition, total flavonoids and antioxidant compound levels also increased with increasing water stress. The amounts of flavonoid compounds obtained from the trial groups were 0.146, 0.373, and 0.412 mg-1g, respectively, while the antioxidant levels determined by the DPPH method increased in quantity with increasing water stress, similar to other biochemical compounds. According to these results, it was determined that the yield of pickling hot peppers decreased in the case of water shortage that the plants would face in cultivation, but there was an increase in some biochemical compounds.
