The purpose of this study was to determine the factors affecting the 305-day milk yield of dairy cattle by using Regression Tree Analysis (RTA). The data set of this study consisted of 8 different cattle breeds grown in Turkey. Breed (B), Province (P), Lactation Length (LL), Service Period (SP), Dry Period (DP), Parity (PR), Calving Year (CY), Calving Age (CA) and Calving Month (CM) were used to predict the 305-day milk yield. Results of RTM showed that the usage of this method might be appropriate for determining the important factors that would be able to affect the 305-day milk yield (R2=71.3%). It was seen that the most important factors affecting the 305-day milk yield were the Breed, Lactation Length, Province, and Parity. Therefore, those selected factors were more efficient than the others in predicting the 305-day milk yield. RTA results also indicated that the lowest milk yield was estimated for Jersey, Jersey Crossbred, and Yerli Kara. Among the highest 305-day milk yield cows, the milk yield estimates of the cows in the second, third, fourth, fifth, and the sixth parities were found significantly higher than that of the cows in the first and seventh parities.

This study aimed to determine and compare aluminum (Al), arsenic (As), cadmium (Cd), and lead (Pb) levels in conventional and organic milk, white cheese, and butter samples which are sold in the markets of Turkey. Within the scope of the study, totally 72 samples (36 for organic, and 36 for conventional) were collected, and analyzed between March 2010 and February 2011. After the samples were burned by microwave burning, element measurements were performed on atomic absorption spectrophotometer (AAS) device. As a result of the study, on the 49 samples (29 conventional, 20 organic) of the 72 collected product, element levels were determined above the limit of detection (LOD) (0.02 ppm). Pb and Al were the most common elements above the LOD. However, milk samples with a Pb level above the LOD still remained below the limit reported by the Turkish Food Codex Regulation for Contaminants. Since Turkish Food Codex Regulation does not have legal limits for Al, As, Cd and Pb for dairy products (cheese and butter), it was accepted as safe in terms of Al, As, Cd and Pb according to food limits in Turkish Food Codex and ADI values of FAO / WHO.

South East Anatolia Region has a large genetic plant diversity due to its physical and different climatic charesteristics. These plants are potential sources of antioxidants that prevent oxidative stress caused by oxygen and photons. In recent years, it has become important to study the antioxidant capacity of many molecules found naturally in foods and biological systems. The reason for this is that it is believed that when the consumption of food rich in antioxidants is increased, the risk of developing different degenerative diseases will be reduced. In this study, it was aimed to measure the antoxidant capacity of Quercus infectoria, G.olivier gal seeds grown in Southeastern Anatolia. Q. infectoria gal seeds from Sanlıurfa province were used in our study. Q. infectoria gal seeds were extracted with water, ethanol and methanol and then antioxidant enzyme activities (catalase and superoxide dismutase) and malondialdehyde levels, which are indicators of oxidative stress were determined by spectrophotometric methods. It was found that the antioxidant capacity (catalase and superoxide dismutase activities) of extracts obtained from ethanol and methanol were higher and their malondialdehyde levels were statistically lower than those obtained from water. However, it was determined that there was no statistically significant difference between the antioxidant capacity and malondialdehyde levels of the extracts obtained from methanol compared to the extracts obtained from ethanol. It has been concluded that Q. infectoria gal seed has a effective antioxidant effect. In addition, it was observed that extracts obtained from ethanol and methanol have higher antioxidant capacity than extracts obtained from water.

This study was conducted to collect local Okra (Abelmoschus esculentus L.) genotypes belonging to Malvaceae (Mallow) family in the Northern Cyprus and morphological characterization of this collected material. On the other hand, due to the limited studies on collection and morphological characterization, which are the first step of breeding; the genetic potential of the local okra genotypes of Northern Cyprus has not been determined before. This research was carried out in two stages as the collection and morphological characterization of genotypes. In the first stage of the study, it was aimed to collect local okra genotypes and a total of 58 different locations were reached in line with this target and 24 samples of okra genotypes were collected from these areas. In the second year of the study, morphological characterization studies of 24 okra genotypes from the collected genetic material were carried out according to UPOV and IPGR criteria. As a result of morphological characterization showed that 24 okra genotypes can be categorized under 6 different groups. The regenerated seeds of these 6 different genotypes were preserved. In conclusion, although morphological characterization analyses performed in this study are the methods used to differentiate new species from each other, but it will be insufficient alone. Therefore, it is concluded that this method will be used in coordination with molecular characterization studies to provide more reliable results.

Family health centers in Turkey started to be implemented for the first time in Düzce in 2004 years within the scope of Law No. 5258. While determining the physical conditions of the places where family health centers are built, the first item in the regulation is that the building should be easily accessible. This situation shows the importance of the subject in terms of accessibility. While determining the features of the places where FHCs will be made, environmental characteristics are also taken into consideration. Environmental features are effective in determining the FHCs location in different ways. These impacts are divided into two groups: the physical features that pavements, roads and parks can include, and the social, cultural and institutional features of neighborhoods that include local social ties and collective activities. From this point of view, the importance of the location of family health centers relative to roads and houses is understood. The aim of this study is to examine the accessibility of Family Health Centers in Konyaaltı, Antalya, on a neighborhood basis using Geographic Information Systems. Konyaaltı has 21 Family Health Centers. As a result of the analyses, it was determined that most of the neighborhoods had problems in terms of accessibility, while a very few of them did not experience problems in terms of accessibility. In terms of the total number of buildings, the ratio of buildings that are 500 meters walking distance from any family health center by using highways is 35.56%. With these rates, 3,634 of the 10,2018 buildings remain within the limits of the regulation. Finally; suggestions were made to increase accessibility to these areas.

Pterostilbene (PTE) (3-5 dimethoxy-4-hydroxy-trans-stilbenes) is an analogue of resveratrol. It is extracted and isolated from a natural source of the heartwood of Pterocarpus marsupium Roxb., red grape skin, and blueberries (Vaccinium spp.). Substantial evidence suggested that PTE displayed numerous preventive and therapeutic properties in many metabolic disorders such as diabetes and obesity. Metabolic diseases result in Insulin resistance (IR) which advances to impaired sensitivity to insulin-mediated glucose disposal. The prominent role of SIRT (silent information regulator proteins) is now getting emphasized in metabolic disorders. SIRT1 represses Uncoupling protein 2 (UCP2) expressions which are further responsible for improving synthesis of ATP from glucose. This results in improving glucose utilization and insulin secretion, thus preventing IR. SIRT1 also exhibits prominent role in facilitating fatty acid mobilization thereby inhibiting adiposity. Metabolic disorders are therefore the consequences of SIRT1 downregulation. Pterostilbene, being a SIRT1 activator, increases insulin sensitivity reduces adiposity, therefore can prove to be beneficial in diabetes as well as obesity. The review summarizes therapeutic effects portrayed by Pterostilbene via the SIRT1 pathway in metabolic diseases.

Recently, most genomic research has focused on genome editing methods to develop new technologies that could be easy, reliable, and feasible to edit plant genomes for highly productive agriculture. Genome editing is based on alternating a specific target DNA sequence by adding, replacing, and removing DNA bases. This newest technology called CRISPR/Cas9 seems to be less time-consuming, more effective and used in many research areas of plant genetic research. CRISPR/Cas9 systems have many advantages in comparison with ZFNs and TALENs and has been extensively used for genome editing to many crop plant species. Around 20 crop species are successfully worked out for trait improvements, for example, yield improvement, disease resistance, herbicide tolerance, and biotic and abiotic stress management. This review paper will overview recent advances in CRISPR/Cas genome editing research in detail. The main focus will be on the use of CRISPR/Cas9 technology in plant genome research.

In this study, in which the effects of different applications of vermicompost on the yield and quality of San Andreas strawberry variety were investigated 15, 30, 45, 60 g vermicompost was applied per plant. First flowering, first and last harvest dates, number of fruits per plant, yield per plant (g/plant), fruit weight (g), fruit flavor, macro and micro nutrient content, organic acid amounts were examined. The results showed that the differences between treatments in yield per plant were statistically significant. The highest total yield per plant was obtained from V45 and V30 applications with 972.8 g and 878.9 g respectively and the lowest yield was obtained from the control application with 384.2 g per plant. The largest fruits were obtained from the V60 (19.5 g) application. It was determined that nitrogen, phosphorus, potassium, magnesium, sulfur, manganese, iron, zinc and boron concentrations in the leaves of strawberry plants fertilized with vermicompost were higher than the control. The highest values in organic acid values were determined in oxalic, propionic, malonic, lactic, fumaric and succinic acids in V60 application (5.62, 11.16, 49.00, 104.98 µg/100 g respectively). It seems that the application of vermicompost fertilizer in strawberry cultivation has a positive effect on yield and quality characteristics.

Since coliform bacteria are common both in the intestine and in nature (soil, plant, etc.), they are considered as a sanitation indicator in the food industry. It is known that the majority of bacteria defined as fecal coliform in the coliform group are Escherichia coli. The presence of E. coli or fecal coliform bacteria in any sample is an indication that the necessary hygienic measures are not taken during production, storage, and sale. That means the sample is directly or indirectly contaminated with faeces, and/or other intestinal pathogens may also exist. In this study, raw milk, freshly squeezed fruit juices, unpackaged ice cream, shaved ice, and ice-cold samples were purchased from the famous touristic destination Fethiye and analyzed for coliform bacteria. For this purpose, the samples were purchased from local marketplaces, buffets, cafes, patisseries, restaurants, and roadsides at Fethiye. In total 60 samples were analyzed using Violet Red Bile (VRB) Agar. The results of coliform bacteria ranged

Covid-19, which affects the whole world and is accepted as a pandemic by the world health organization, caused millions of people to die. The elderly are in the group with the highest risk of losing their lives due to the Covid-19 virus. Stricter restrictive / protective measures have been taken for the elderly in Turkey, as in the whole world. With this research, it is aimed to evaluate the sociological and psychological effects of the "elderly", who are one of the health risk groups of the society, in terms of landscape architecture, during the pandemic days when they had to experience various problems after the outbreak. In the study, face-to-face and online questionnaires were applied to individuals aged 50 and over on a voluntary basis. As a result of the study, it was determined that the implementation of curfews and restrictions for the elderly and the formation of an isolated lifestyle from other age groups caused an increase in loneliness and anxiety levels and negative psychological effects. It has been revealed that the activities that individuals will carry out in the green area, their conversations and socializing with their peers, and walks in the open area have a positive psychological and sociological effect for the elderly. It has been determined that the elderly who become lonely and depressed at home with the restrictions imposed under pandemic conditions want to be in green areas. The sociological and psychological positive effects of being in green areas and spending time, and the changes in the behaviour and emotions of the elderly who have pandemic restrictions paralleled the response of the participants to the questionnaire.
