2022
Seyfullah Cengiz | Murat Reis Akkaya | Osman Kola
Peanut allergens adversely affect the health and quality of life of millions of consumers worldwide. The seeds of the peanut plant (Arachis hypogaea L.) contain a number of allergens that trigger the production of specific IgE antibodies in allergy-prone individuals. Currently, 18 proteins found in peanuts are accepted as allergens. These allergens are named from Ara h 1 to Ara h 18. Ara h 2, Ara h 6 and Ara h 7 are from albumin, Ara h 1 and Ara h 3 are from globülin. Ara h is the abbreviation of Arachis hypogaea, the Latin name for peanut. A peanut allergy is a reaction that occurs shortly after eating to peanuts or peanut products. It has various symptoms that can go up to swelling of the tongue, itching of the palate, itching and burning in the throat, itching in the eyes and nose, nausea, vomiting, abdominal pain, shortness of breath, wheezing, bruising, chest pain, hives, low blood pressure and shock. In this review, the properties of peanut allergens and the methods of reducing the allergen effect will be reviewed.

The effect of antifreeze protein type III (AFPIII) and human heat shock protein 70 (HHSP70), added to the vitrification medium of mouse embryos, on post-freeze/thaw in vitro embryonic growth rates and cell numbers were investigated. In total 20 female mice were synchronized. After synchronization, 2 females and 1 male were mated in the same cage. Twenty-four h after mating, the embryos were collected at the pronuclear stage. In total 8 groups were established, including a positive control group (C+), a negative control group (C-), and treatment groups that were vitrified in a medium added with 200, 400 and 800 ng/ml of AFPIII (AFPIII200, AFPIII400, AFPIII800), and 1, 2 and 4 µg/ml of HHSP70 (HHSP70-1, HHSP70-2, HHSP70-4). Solid surface vitrification (SSV) medium was prepared for the vitrification of the embryos. Once thawed, in vitro development rates of embryos were followed at 24, 48, 72 and 96 h. Four embryos, which progressed to the full blastocyst stage, were taken from each group and stained with the Hoeschst 33258 and propidium iodine (PI) dyes to determine the inner cell mass (ICM), trophectoderm (TE) and total cell numbers. The groups showed statistically significant difference for in vitro embryonic development rates at 48, 72 and 96 h (p

The identification of plants in which the bees forage is key in establishing bee farms and increasing honey production. In this study pollen analysis of honey samples from the southeastern part of Nigeria was carried out to ascertain their floral sources and ecological origin. The honey samples were acetolyzed and microscopically studied to determine the pollen types. A total of seventy-one pollen types belonging to forty-one families of plants were identified. The honey samples were dominated by pollen grains from the families of Arecaceae, Euphorbiaceae, Myrtaceae, Irvigiaceae, Fabaceae, Combretaceae/Melastomataceae, and phyllanthaceae. Some of the dominant pollen grain identified include Elaeis guineensis, Alchornea cordifolia, Hymenocardia acida, Ocimum gratissimum, Syzygium guineense, Nauclea latifolia and Afzelia africana. Out of the six samples studied Njikoka sample was monofloral having Mimosa pigra as predominant pollen while Ayamelum, Ekwusigo, Nsukka, Ezeagu, and Udenu samples are multifloral containing Elaeis guineensis, Phyllanthus sp., Piliostigma reticulatum, Irvingia sp., Alchornea cordifolia, and Lannea sp. as major secondary pollen. All the samples analyzed have Elaeis guineensis in common except Ezeagu, indicating that these plants are present in all five locations. These results can also be used as a tool in the geographical identification of Southeastern Nigeria honey from other geopolitical zones.

Kani Yavuz
Crop and animal production constitute a large part of the people's livelihoods in Bayburt province. In addition, the province has become one of the important animal husbandry centers of the region due to the fact that it is a transit point between the Eastern Anatolia region and the Black Sea region. But the number of small farms in Bayburt province is still very large, and the number of farms that are members of grower organizations is quite small. In addition, the migration of the young population from villages leads to an increase in the average age of the population engaged in animal husbandry and a decrease in the number of animals that can be raised depending on the labor force. In this review, the general status of cattle and small ruminants livestock in Bayburt province was given and the level of livestock in Bayburt province was revealed with current data.

Kazlarda Selüloz ve Selüloz Fraksiyonlarının Sindirimi Full text
2022
Süleyman Çalışlar
Kanatlı hayvanların sindirim sistemi kısa olduğundan yemlerin sindirim sisteminde kalış süresi kısadır. Buna ilave olarak, kanatlı hayvan türlerinin birçoğunun selüloz, selüloz fraksiyonları (ADF ve NDF) ile nişasta tabiatında olmayan polisakkaritleri sindirebilme ve bunlardan yararlanma yetenekleri düşüktür. Bundan dolayı kanatlı hayvanların beslenmesinde besin madde içeriği yüksek olan daha pahalı yemlerin kullanılması zorunlu hale gelmektedir. Bu durum ise beyaz et ve yumurta gibi hayvansal ürünlerin fiyatlarını yükseltmektedir. Kanatlı hayvan beslemedeki bu dezavantajı avantaja çevirmek için sindirim sistemi daha güçlü, selülozca zengin ucuz yem kaynaklarını daha iyi sindirebilen, kaba yemlerden daha iyi yararlanabilen alternatif kanatlı hayvanlara ihtiyaç duyulmaktadır. Sahip olduğu özellikler açısından değerlendirildiğinde, ucuz yem kaynaklarından daha iyi yararlanabilecek kanatlı hayvanlardan birisinin de kaz olduğu görülecektir. Kazların selülozca zengin kaba yemlerden etkin bir şekilde yararlanabilmesi, yem giderlerini azaltmak suretiyle hayvansal ürünlerin daha ekonomik olması için uygun bir fırsat sunmaktadır. Diğer kanatlı hayvanlara göre kaba yemlerden daha iyi yararlanmasından dolayı beyaz et ve yumurta üretimi için kaz yetiştiriciliğinin yaygınlaştırılması özellikle kırsaldaki nüfus için önemli bir gelir ve geçim kaynağı olabilir. Bu derlemede, kazların mikrobiyal sindirim özellikleri, selüloz başta olmak üzere selüloz fraksiyonlarından ve nişasta tabiatında olmayan yem unsurlarından yararlanabilme yetenekleri incelenmiştir.

Rifat Olgun
The increase in the world population and rapid urbanization cause different types of pollution such as air, water, soil and noise. Today, this situation significantly affects the quality of life in densely populated settlements both in the world and in Turkey. Noise pollution, which is one of the important types of pollution, especially in urban areas, is increasing day by day due to anthropogenic effects. Studies conducted by the European Noise Directive (END) show that noise pollution is one of the important factors that cause health problems. Parks are places that allow children trapped in the structural environment in urban life to get to know nature and play games in open spaces. In particular, the children's playgrounds in the parks allow children to play and socialize in the open area and also allow parents to rest. However, park users may be exposed to noise pollution due to high-level noises originating from vehicle traffic, user density, and children's playgrounds in these places. This situation adversely affects the physical and mental health of the park users. The aim of the research is to determine the noise level in children's playgrounds in parks and to develop suggestions for reducing this noise level. As a result of the preliminary studies carried out in this context, Antalya/Kepez Dokuma Park was determined as a research area. Zones were created at certain intervals around the children's playground in the research area. And noise levels were measured on weekdays and weekends from the noise measurement points determined in these zones. The results obtained show that the noise pollution caused by the children's playgrounds in the parks and environmental factors is at a high level. In this context, landscape design and planning proposals have been developed to reduce noise pollution from children's playgrounds and environmental factors.

In this study, a total of 364 samples were collected and 349 of them belonged to, 349 specimens of Dasyatis pastinaca, 6 of Gymnura altavela, 5 of Torpedo marmorato, 2 of Aetomylaeus bovinus and Mustelus mustelus, were obtained by-catch in trammel nets off the Izmir Bay (Aegean sea coast of Turkey) during period of spring in 2018. Males of D. pastinaca ranged from 28–62 cm and females from 31.5-94 cm total length. The analysis of the angular coefficient (b) demonstrated that growth (in weight) in relation to length was isometric in males and females of D. pastinaca. Morphologic measurements of a total of 60 individuals to represent all individuals of the population, t test in independent groups to determine differences in males and females and all other morphometric measurements were statistically tested by multiple regression analysis (stepwise method). Therefore, difference between mean values obtained according to sexes was not found different. However, A linear correlation between weight- pelvic length for females and weight- preanal length for males according to multiple regression analysis in male and female individuals. Isometric and positive allometric growths were calculated for species of Torpedo marmorata and Gymnura altavela, respectively.

In recent years, it has gained importance to develop models to determine the contribution of parks to reducing the temperature together with their surroundings. ENVI-met, which is used for this purpose, allows simulations for different conditions/materials with projections over many years. This study aims to determine the temperature levels arising from the surface materials and the projections of long years in the near areas of Cumhuriyet Park in Çukurova District of Adana. The study consists of 3 stages. In the first stage, information about the subject was gathered together. In the second stage, modeling was carried out using ENVI-Met 4.4.5 climatic simulation software in order to determine the temperature levels caused by different materials in the study area. The scenario for the future has been put forward. The data obtained in the third stage of the study were evaluated and suggestions were presented. As a result of the study, it was determined that Cumhuriyet Park, which is one of the important green areas of Çukurova district, contributed significantly to the decrease in the temperature level around it. This contribution is felt more intensely especially in the immediate vicinity of the park. It has been shown that the effect decreases with distance from the park. In the scenario put forward at the end of the 28-year period, it is predicted that the temperature level of the parking area will increase by approximately 2.4°C. This study reveals the importance of the selection of soil materials in preventing the warming of cities because of climate change experienced all over the world. In this context, local administrations attach importance to efforts to increase the quality of urban life; developing strategies in this regard is important for achieving results.

Tahini is a food product that is frequently preferred both directly and as a main ingredient in various ready-to-eat food products and is consumed with interest, especially in the Middle East geography. Its reputation has recently spread across continents to countries like Canada and the United States of America. Tahini was subjected to a number of analyses to ascertain its physicochemical and microbiological quality within the context of the study since it is a highly consumed product with high consumption and demand values. In this context, tahini samples of 10 different brands were collected from producers and commercially sold markets in Balikesir and Bursa. Samples were taken from two different lot numbers for each company. As a result of the analyzes made on the tahini samples, it was determined that the total oil amount of the samples changed between 49.76-58.7%, the salt amount changed between 0.001-0.0027%, the ash amount was between 1.02%-1.28%, and the moisture value was between 1.1-1.5%; as a result of microbiological cultivations in which the presence of yeast and mold were analyzed, an average of 75 CFU/g viability was determined, while Escherichia coli, which was screened as an indicator of fecal contamination, Staphylococcus aureus and Salmonella spp, which are pathogenic microorganisms, were not found to be contaminated in all tahini samples. One of the tahini samples was not found in accordance with the Turkish Food Codex Tahini Communiqué (TFC) in terms of the amount of oil. It is concluded that 90% of the samples were manufactured in line with the TFC when the results of the chemical and microbiological analyses were combined.
