Blueberries have been drawn more attention in recent years for their antioxidant capacities and proposed health benefits. Pulsed ultraviolet (PUV) light is known for its disinfection effects on the surface of fresh fruits. This study’s aim was to examine the effects of PUV light on naturally present microbial load, antioxidant capacity, and antioxidant enzyme activity of fresh blueberries. Fresh blueberry samples were treated for 30, 60, 90, and 120 s. Samples were stabilized at 13 cm away from the PUV lamp before treatment. Total Aerobic Plate Count (TAPC) and yeast and mold count reduction were observed the highest in samples treated for 90 s, 1.97 and 1.27 log CFU/g, respectively. Antioxidant capacity levels were significantly different for treated samples for 60 and 90 s in FRAP analysis, whereas no differences were observed in results of DPPH analysis. Superoxide dismutase (SOD) activity as antioxidant enzyme had no difference, however, glutathione peroxidase (GPx) increased by 50% with PUV treatment for 120 s. PUV light treatment of fresh blueberries for 90 s was determined as ideal exposure time among tested time intervals of this study. PUV light illumination can generally enhance antioxidant capacity and antioxidant enzyme activity of fresh blueberries and decrease the population of natural microorganisms of fresh blueberries and similar small fruits.

The aim of study were to present relationships between birth weight of 94 Holstein calves with genotype structures of each sample’s Growth Hormone (GH) determined through PCR-RFLP method and to detect the population’s genetic variation by determining the genotype and allel frequency distribution. In the study, according to the analysis result, it was determined that Growth Hormone gene LL genotype was 41.9 kg, LL was 40.8 kg, and VV was 42.2 kg for the birth weight. A significant relationship between birth weight with GH genotypes could not be found. It was seen that the calf population is not stable according to Hardy-Weinberg genetic balance test.

Since the national farmers' day on May 12, 2017 in Kaya, Burkina Faso, the debate on agriculture has been to establish the agricultural entrepreneurship through the concept of agriculture as a family business (ACEF). And it is from this perspective that this study was conducted to analyse the financing possibilities open to family farming and to deduce the constraints of the transition from family farming to enterprise farming. To do this, we used the exegetical method to characterize the existing agricultural formations, to identify the means of financing and the constraints of the agricultural transition. The agricultural sector is strongly dominated by family farming with low physical and financial capital. The means of financing are self-financing and external financing. However, the transition will not be without problems because there are technical and political constraints to overcome.

Developing alternative control methods such as using beneficial microorganisms and their metabolites to control the plant diseases has gained so much importance along recent years and research on this area are increasing day by day. In this study the possibilities of using microorganisms which have antimicrobial effects on controlling soil-borne fungi at strawberry production were investigated. Effects of different lactic acid bacteria (LAB) strains were studied in vitro and in vivo against the development of several soil-borne fungi. LAB were screened for antifungal activity by using cell free supernatant against Fusarium sp., Rhizoctonia sp., Macrophomina sp., Botrytis sp., Phtopythium sp., Cylindrocarpon sp. and Pestalotiopsis sp. Cell free supernatant of LAB isolates showed antifungal activity against fungi. In vitro effective strains of LAB were used in pot experiments to search their effects on fungal development and the development of the plant. While the antifungal effects of all LAB strains tested in vitro experiments exhibited promising results, in vivo experiments revealed similar effects on different fungi genera.

One of the alternative therapeutic methods is herbal medicine. Leontice leontopetalum belongs to Berberidaceae family. The aim of study was investigated the extract of LL on human pancreatic beta cell-treated with STZ. Materials and methods: The human pancreatic beta cell (1.1B4) line was used the current study. LL’s extracts (1, 10, 100, and 1000 ug/ml) were supplemented in media for twenty-four hours and/or after STZ treatment (10 and 20 mM). Cells survivals (MTT), cells proliferation were shown by using xCelligence. Insulin content and releasing were measured at 1.1, 8.4 and 16.7 mM glucose concentrations. Results: The result of MTT was shown that cell survival was decreased, based on dose-dependent. When looked at xCelligence results, cell proliferation in STZ groups and the lowest and highest concentrations of LL were attenuated in a dose-dependent manner. Also, cotreatments of LL and STZ were decreased as well. The result of insulin-releasing on glucose induction was shown that STZ concentration gave rise to reduce insulin content at low and high glucose levels. Also, co-treatment of LL and STZ attenuated insulin content based on dose. Conclusion: It was considered that LL treatment led to increased insulin realizing, resulting from decreasing insulin content in diabetic beta cells, but decrease cell survival.

Bu çalışmada kiraz ve kayısı ağaçlarından sızan reçineler yenilebilir kaplama materyali olarak kullanıldı. Reçinelerin yenilebilir kaplama olarak uygun olup olmadıkları bazı kimyasal özellikleriyle incelendi. Karbon, hidrojen, azot ve kükürt yüzdeleri elementel analiz ile belirlendi. Yapılan analizler sonucunda her iki reçinenin de fenolik madde bakımından zengin olduğu bulundu ve antioksidan kapasitelerinin yüksek olduğu tespit edildi. Termal analizlerle reçinelerden elde edilen filmlerin ısıya karşı davranışları ve ağırlık kayıpları belirlendi. Bu analizlere göre, filmlerin 400°C’ye kadar ısıya dayanıklı oldukları bulundu. Filmlerin SEM ile elde edilen yüzey görüntülerinin homojen ve düzgün bir yapıda oldukları görüldü. Daha sonra, reçinelerden elde edilen film çözeltileriyle çilek ve yenidünya meyveleri kaplandı. 4±1°C’de buzdolabında muhafaza edilen kaplamalı/kaplamasız meyveler; raf ömrü, organoleptik ve mikrobiyolojik özellikler bakımından karşılaştırıldı. Filmlerin kaplanmış meyvelerin raf ömrünü uzattığı görüldü. Depolama sonunda kaplamasız örneklerin toplam bakteri, maya-küf ve koliform bakteri düzeyleri en yüksek seviyedeydi. Ayrıca, kaplamalar meyvelerin organoleptik özelliklerini olumlu etkiledi. Duyusal analiz testine göre kaplamalı meyveler, kaplamasız meyvelerden daha yüksek puanlara sahip oldular. Kiraz ve kayısı ağacı reçineleri yenilebilir kaplama olarak kullanıma uygun materyallerdir.
