Bitkilerden elde edilen ekstrelerin birçoğunun biyolojik etkileri ve etki mekanizmaları hakkındaki bilimsel veriler hala yetersiz olmakla birlikte bu konuya olan ilgi her geçen gün artmaktadır. Bu çalışmada, Rumex crispus (Evelik) bitkisi mevsiminde Sivas yöresinden toplanarak kurutulmuş ve sonrasında yapraklı kısımlarından etanol, metanol ve su ekstraksiyonları elde edilmiştir. Çalışmanın amacı, elde edilen her bir ekstrenin bazı mikroorganizmalar üzerindeki antimikrobiyal aktivitelerinin değerlendirilmesi, toplam antioksidan seviyesi (TAS), toplam oksidan seviyesi (TOS), oksidatif stres indeksi (OSI) değerlerinin ve çeşitli hücre hatları üzerindeki anti-kanserojen niteliklerinin ortaya konulmasıdır. TAS, TOS ve OSI değerlerini tespit etmek için Rel Assay Diagnostics kitler kullanılmıştır. Bitki ekstrelerinin mikroorganizmalara karşı minimum inhibisyon konsantrasyonunu (MIC) belirlemek amacıyla mikrodilüsyon broth yöntemi kullanılmıştır. Çalışmada antimikrobiyal aktivite analizleri, Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922), Bacillus cereus (ATCC 11778), Klebsiella pneumonia (ATCC 13883), Candida albicans (ATCC 10231) ve Candida tropicalis (DSM 11953) mikroorganizmaları kullanılarak yapılmıştır. Normal fare fibroblast hücre hattı ve 3 farklı insan kanser hücre hattında MTT yöntemi ile bitki özütlerinin sitotoksik aktivitesi belirlenmiştir. Sonuç olarak, evelik bitkisinin etanol, metanol ve su ekstraklarının denendiği mikroorganizmalar üzerinde antimikrobiyal aktivitesinin bulunmadığı, yüksek düzeyde antioksidan aktiviteye sahip olduğu ve bazı hücre kültürlerinde sitotoksik aktivitesinin olduğu tespit edilmiştir.

In continuous monitoring and control systems as required by automation, biosensors are greatly advantageous with their precision, stability, ease of use and response rates. In this study, a new amperometric glucose sensor has been fabricated based on a composite film prepared by electrochemical polymerization of carbazole derivative with having free amino group in presence of the Keggin type polyoxometalate (POM) anion, (nBu4N)3[PW9O34(tBuSiOH)3], in order to meet the needs of the sector. The enzymatic biosensor was prepared by immobilizing the Glucose Oxidase (GOx) enzyme to the surface modified with the POM/PAAC composite. Biosensor preparation and working conditions were optimized and analytical characterizations was carried out. The amperometric response of the POM/PAAC-GOx modified electrode versus varying concentrations of glucose was studied at a potential value of −0.7 V (Ag/AgCl). When the data obtained from these surfaces can be prepared in a short time, it was determined that they are sensitive to the presence of glucose in food samples such as cola and fruit juice. One of the innovations of this study is the shortening of the response time and the easy preparation of the biosensor. In addition to high linearity, short response time and long shelf life advantages in determining the glucose content in foods, it is thought that it will be an economical alternative with its easy preparation, ease of application and time and chemicals gain in measurements.

The aim of this study was to determine the macroscopic and microscopic spermatological parameters of the Karayaka rams grown in public hands. Out off-season sperm couldn’t be taken from the rams. During the season, semen was collected from all 2-4 age of Karayaka rams (n = 10). Weight (kg) and circumference of the scrotum (cm) were also recorded. When the collected spermatozoa were examined, it was found that the weight variable correlated only with the pH variable. The correlation coefficient calculated between weight and pH was -0,802 and it was found to be statistically significant. The correlation coefficient, which calculated as 0.680, between the circumference of the scrotum (cm) and mortality (% Dead-Live) shows that one feature increases while the other increases significantly. Viscosity (1-5) was correlated only with mass activity (Mass Activity 0-4), and the degree of this relationship was calculated as -0.655. Variables were not associated with sperm volume (ml), motility (%) and density (109).

Pulses in Pakistan is used in combination with cereals to balance the diet. Its area and production is decreasing for last many years. In the barren and partly arid regions, water shortage is the major component that restricts yield. Using of drought resistance plant is one of the best ways for good cultivation under drought condition. As the pulses have great nutritional and economical values and drought stress affect their morphological features. The legume yield is mostly cultured in rain fed region of the Punjab where they bear a slighter quantity of water situation resulting in low yield of bean. To overcome these problems it is necessary to get knowledge about the performance of different lines of different pulses crops under water stress conditions. That’s why in this paper the information about the previous literature has been discussed.

Poor soil fertility is important constraints that limited crop production in Ethiopia. The Masha district was highly prone to phosphorus fixation with ions like Aluminum ion since soil of the area is prone to acidity. This experiment was therefore conducted to investigate the effect of of phosphorus fertilizer with agricultural lime, coffee husk ash and coffee husk charcoal on yield of faba bean and agronomic efficiency of the fertilizer on acidic soils of Masha district. Field experiment involving two rates of phosphorus (23 and 46 kg P2O5/ha) and the three soil amendments was in randomized complete block design with three replication. The result indicated that significantly high grain yield was obtained from integrated application of 46 kg P2O5/ha with the agricultural lime, coffee husk ash and coffee husk charcoal with the observed values of 2265, 1953 and 1943 kg/ha, respectively. Agronomic efficiency significantly great values were obtained from treated with the agricultural lime+23 kg P2O5/ha, agricultural lime+46 kg P2O5/ha, coffee husk ash+23 kg P2O5/ha and coffee husk charcoal+23 kg P2O5/ha with the observed values of 14.86, 14.60 and 10.07, respectively. It can be concluded that 46 kg P2O5 with 2.5 ton agricultural lime, 7.5 ton coffee husk ash or 7.5 ton coffee husk charcoal per hectare on acid soils for high yield and yield components on faba bean at Masha district. When 23 kg P2O5/ha was integrated with the soil amendments, relatively high agronomic efficiency was observed.

The increase of consumer demand for using natural products and reducing the use of non-compostable packaging materials have encouraged research on biodegradable polymers including natural components such as essential oils. Pomegranate seed oil (PSO) has active properties such as antimicrobial and antioxidant activities. The aim of this study was to prepare active polycaprolactone (PCL) films by using PSO. PCL films including PSO emulsions (5-30%), which were stabilized with nanocellulose (NC) particles, were prepared by casting method. The physical and active properties of PCL films were determined by means of water vapor permeability (WVP), mechanical properties, optical properties, release behaviour, and potential antimicrobial activity. The WVP values of PCL films was lower when incorporated with NC-stabilized PSO emulsions. The incorporation of PSO into PCL films in the form of NC-stabilized emulsions significantly reduced the transmittance and lightness values, which resulted in an increase in opacity. In the release tests, the slower release of PSO was observed for NC-stabilized films. The stabilization of PSO with NC showed to be less effective when high concentrations of oil (30%) were used. Film samples showed potential antimicrobial activity against Escherichia coli, and Listeria monocytogenes, however, a clear zone of inhibition around the film samples was not detected. Results also suggested that the antimicrobial effect was dependent on two important factors: the release behaviour of PSO through the film samples and, the direct interaction between PSO and microorganisms. These results showed that the combination PCL films and PSO stabilized with NC could be an interesting approach in active packaging technologies.

Today’s consumers prefer foods with high nutritional value, functional properties and long shelf life. Particularly, interest in fresh fruits and vegetables, which are ready for consumption due to their healthy and nutritious nature, is increasing. However, biological activities such as respiration and transpiration cause loss of water and soluble substances in fruits and vegetables and change the gas concentration in the environment during storage and this situation greatly affects critical quality parameters such as mass loss, nutritional value and shelf life. Minimal processing, such as peeling, cutting or shredding increases the surface area of fresh fruits and vegetables, reduces the shelf life by triggering a variety of enzymatic reactions. The edible film coating is a novel packaging method that is natural, environmental friendly, economic and easily applicable. This innovative technique can be used to produce a product that is closest to fresh fruits and vegetables, maintain the desired quality characteristics, control microbiological spoilage and extend the shelf life. In addition, the use of plant-based materials in film coating applied to minimally processed fruits and vegetables attracts the consumers and increases the confidence in products. In this review, the information about the current applications of edible coating to the minimally processed fruits and vegetables and the effect of this application on some physical, chemical, sensory and microbial changes occurring in the products during the storage period has been presented.

In recent years, the world population, urbanization process and need for natural water resources have increased. Therefore, providing the safe and clean drinking water has become an important topic of our day. This research was carried out to determine the bottled water consumption habits and purchasing behaviours of consumers. Primary data were obtained from 384 consumers living in urban areas of Adana province. The demographic characteristics and consumption habits of consumers were determined by calculating frequencies, ratios and averages. Factor analysis was used to determine the factors that affect the purchasing behaviours of the consumers and the cluster analysis were used to distinguish consumers with different perception levels from those with similar characteristics. Results indicated that 40.4% of participants consumed bottled water and 85.2% of these consumers took into account the brand of bottled water. Factor analysis revealed that 3 factors, product characteristics, packaging and price, and recognition affected purchasing behaviours in this sample. As a result of the K-means clustering analysis consumers in this study were divided into 3 groups. The most important factors for consumers in these observed clusters were shelf life, product freshness and product hygiene.
