İnsanların beslenmesinde gluten içeren besinler önemli yer tutmaktadır. Gluten metabolizması bozukluğuna bağlı oluşan hastalıklar bulunmakta olup bunlar çölyak hastalığı, buğdaya karşı IgE aracılı alerji ve çölyak dışı gluten duyarlılığı olarak sınıflandırılabilir. Bireylerin gluten duyarlılıkları arasında farklılıklar olup gluten duyarlılığı olan bireylerin gluten içeren besinleri tüketmeleri durumunda en başta bağırsak dokusu olmak üzere birçok dokuda histopatolojik yapılarında ve otoimmun sistemlerinde önemli değişiklikler meydana gelebilir. Dokuların histopatolojik yapısındaki değişiklikler dokulara göre değişmektedir. Otoimmun sistemdeki değişiklikler ise Transglutaminaz, Gliadin, IgA, IgG, CD4 ve CD8 gibi parametrelerden en az birinin veya birkaçının incelenmesi ile tespit edilebilir. Gluten metabolizması bozukluğuna bağlı oluşan hastalıklarda etkili tedavi şekli glutensiz/gluten kısıtlı diyet olmakla birlikte bağışıklık sisteminde rol alan mekanizma ve moleküllerin saptanması yeni tedavi yöntemlerini oluşturulmasına yol gösterebilir. Bu çalışmada amaç gluten ve gluten metabolizması bozukluğuna bağlı oluşan hastalıklar arasındaki ilişkinin derlemesidir.

Birçok Avrupa ülkesinde hava kirliliği dolayısıyla çevrenin korunması önemli konuların başında gelmektedir. İsviçre’de yapılan araştırmalar, karayolu dışı taşıt trafiğinin hava kirliliğinin önemli bir bölümünün nedeni olduğunu göstermiştir. Tarım traktörleri de karayolu dışı taşıt trafiğinin önemli bir bölümünü oluşturmaktadır. Gelişmiş ve gelişmekte olan ülkelerde traktör sayılarında hızlı bir artış görülmektedir. Traktör sayılarının bu artışı nedeniyle traktör egzoz emisyonları ve bunların çevreye olan etkileri üzerinde büyüyen bir ilgi vardır. Doğru emisyon değerlerinin belirlenmesi ve kullanılan ölçüm metotları önem kazanmıştır. Traktör motorlarının tip onayı için bir motor test donanımında emisyon ölçümlerine yönelik düzenlemeler mevcuttur, ancak traktörün farklı çalışma koşullarında emisyon ölçümleri için bir prosedür mevcut değildir. Yapılan çalışmalar traktörlerin farklı çalışma koşullarında ölçülen egzoz gazlarının, emisyon test yöntemlerindeki sabit durum koşullarında elde edilen değerlerden daha yüksek olduğunu göstermiştir. Bu sonuçlar, emisyon ölçümünde kullanılan test prosedürlerinin değiştirilmesinin gerekliliğini ortaya çıkarmaktadır. Yeni testlerin geliştirilmesi, traktörlerden kaynaklanan egzoz emisyonlarını azaltacaktır.

This review investigates the effects of heat and drought stress on future food security of Turkish agriculture. Temperature average is expected to rise to 3.2°C at the end of the current century while annual precipitation will decline more than 10% in the west and south and rise by 20% in the north of Türkiye, implying that climate change will affect ecosystem sustainability. It is therefore crucial to develop strategies to mitigate and adapt to climate change such as adjusting the planting schedule, reduced tillage, fertiliser microdosing, pre-sowing seed treatment, and the application of growth promoting bacteria to improve tolerance to stress by comprehending how plants respond physiologically and biochemically under these stress conditions. Long-term heat stress may hinder photosynthetic electron transport, decreasing the plant's ability to make use of energy for photosynthesis. The immediate response of plants under drought stress involves closing stomatal openings to reduce water loss through stomatal conductance. Combined heat and drought stress have a greater adverse effect on plant development and production than their effects in isolation. Plant phenotyping can play a major role in “climate-proofing” Turkish agriculture through the identification and development of crop varities with improved prouctivity, climate resilience and input requirements. Digital agriculture will also improve the efficiency of Turkish agricultural systems as the adapt to a hotter drier climate. To ensure future food security and the viability of the agro-economic system in Türkiye steps must be taken to make Turkish agriculture more robust in preparation for the impacts of climate change.

When the results of the analyses were examined, out of 97 chemical components of Salvia officinalis plant, 50 components were determined from plants grown with conventional farming methods and 78 components were determined from plants grown with organic farming methods. Of the 38 components detected in Origanum onites, 36 components were determined from plants grown with conventional farming methods and 38 components were determined from plants grown with organic farming methods. Out of 60 components of Lavandula officinalis, 40 components were determined from plants grown with conventional farming methods and 60 components were determined from plants grown with organic farming methods. In terms of chemical structure, the components are divided into different classes as hydrocarbons, monoterpenes, monoterpenoids, sesquiterpenes, sesquiterpenoids, diterpenes, diterpenoids, fatty acids and derivatives, and phenolic compounds.

It is critical that Bangladesh faces water scarcity during the dry season, affecting lentil (Lens culinaris Medik.) yield and some yield components during seedling and flowering stages. Thus, a two-factorial pot experiments (The experiment comprises Factor A: three fertilization levels i.e. F1 = Control [inorganic], F2 = poultry litter-based compost [20 ton/ha], F3 = poultry litter-based compost [30 ton/ha]; Factor B: two irrigation levels such as W1 = 100% field capacity [FC] and W2 = 70% FC) were designed at Hajee Mohammad Danesh Science and Technology University, Dinajpur, from November 2018 to April 2019. And it was investigated how the poultry litter-based composts affected the morpho-physiology, yield and yield components of the lentil (BARI Masur-4) variety under different irrigation stress levels. Obtained results revealed that the tallest plant (30.7 cm at 75 DAS) and maximum branch number per plant (14.1 at 65 DAS), leaf chlorophyll a (0.30 mg/g), highest RLWC (70.28%), lowest proline content (1.57 µ moles g-1 FW), maximum number of pods per plant (39.4 at 75 DAS) and total grain yield (3.62 kg/m2) were recorded from compost F3 (poultry litter-based compost 30 tons/ha) with W1 (100% FC). Results also showed that the yield contributing attributes and yield of lentils were drastically reduced by water stress conditions with different rates of fertilization. In drought conditions (W2 = 70% FC), F3 (30 ton/ha poultry litter-based compost) fertilization produced the highest plant height (30.20 cm at 75 DAS), number of branches (11.5 at 65 DAS), stem dry weight (0.35 g), lowest proline (3.88 µ moles g-1 FW), highest pod number per plant (33.1), weight of 100-seed (2.36 g), total grain weight (2.77 kg/m2), harvest index (58.84%) compared to other fertilizations (F1 and F2). In summary, F3 (30 tons), a compost made from poultry litter, provides better soil conditions under drought conditions compared to F1 and F2 in the year of 2018-19 at the 0 and 20 tons/ha, respectively under the field conditions.

Studies on colic, an economically important metabolic disease in horses, have typically emphasized maintenance characteristics. However, recent research has demonstrated that nutrient content also contributes to the development of colic. Microbial fermentation of the diet begins in the stomach and continues through the hindgut. During this process, various substrates are produced, including acetate, propionate, butyrate, and methane. The gut contains bacteria such as Firmicutes and Bacteroidetes, but the dominance of one over the other is influenced by the type of substrate available in the gut, such as oat, barley, wheat, corn, etc. Microbial fermentation in the equine cecum is markedly influenced by the pH balance of the nutrient metabolism. This has varying impacts on the cecal microbiota. Investigations into the effects of different feeding methods and nutrients have yielded diverse outcomes for the etiology of colic and post-colic nutrition. The objective of this review is to assess the impact of nutrition and diet composition on the etiology of colic in horses, investigate the role of additives in preventing colic cases, and analyze the results of several studies.

Watermelon is a widely cultivated cucurbitaceous crop with economic and dietary significance. The plant's ability to reproduce effectively relies on the harmonious growth and maturation of both its male and female flowers. At the farm level, determining the exact amount of ethylene required to regulate the development and sexual expression of individual floral buds remains uncertain, despite the known influence of exogenously applied ethylene on these processes. The goal of the research was to explore how the ethephon doses influence vegetative characteristics, sex expression, and watermelon yield. The experiment, employing a one-factorial Randomized Complete Block Design (RCBD) comprising five treatments and four replications, was conducted in a farmer's field in Buttabari, Jhapa. Using R-stat software, the data were analyzed at a 5% level of significance. Treatment consisted of Ethephon with four doses namely; 100ppm, 200ppm, 300ppm, 400ppm, and a control. Ethephon application was done twice, once at the two true-leaf stages and another at four true-leaf stages. The study revealed that plant height decreased with ethephon compared to the control, reaching a minimum of 280.1 cm at 400 ppm and a maximum of 307.1 cm in the control. Additionally, the highest branch numbers were observed with ethephon at 200 ppm. The plot treated with 200ppm ethephon was found to be more effective than alternative doses at increasing the total number of female flowers, bearing 15.25 female flowers per plant. Control (166.50 per plant) and 400 ppm (150.00 per plant) had the highest and lowest male flower counts per plant, respectively. A maximum yield of 25.12 t/ha and a minimum yield of 19.1 t/ha were determined at 200 ppm and control, respectively. Hence, farmers are found to benefit from ethephon doses of 200 ppm.
