This study aimed to investigate the impact of the Covid-19 pandemic on eating habits, and lifestyles including sleeping and smoking habits, and physical activity of the Turkish population aged >15 years using a web-survey. The survey was conducted from the 5th of August to the 4th of October 2020 by using an online platform and disseminated through institutional and private social networks (Facebook and WhatsApp) and institutional mailing lists. The questionnaire consisted of demographic information, anthropometric data, changes in dietary habits, and changes in lifestyle habits. The total number of participants was 1020 in the study and 71.1% of them are female, and 80% of the participants were in the 20-59 age range. More than half of the participants (67.42%) declared that their eating habits and lifestyles changed during the Covid-19 pandemic. Most of the participants (63%) declared that there is no special food that can improve their immunity against the Covid-19. Contrary to them, most of those who added certain foods to their diets or increased the consumption of certain foods to improve the immunity (39.8%), declared that they got that information from social media such as Twitter, Facebook, and WhatsApp. In particular smoking habits did not change and sleep hours increased during the Covid-19 period. Concerning physical activity, no significant difference was found between the percentage of people before and during the Covid-19 period.

The Corona Virus is the pandemic all over the world. This viral infection attacked all over the world like as disaster of viral infection which causes morbidity and mortality in different regions of world like Asia, Europe, and Africa etc. The different countries control the spread and complications of covid-19 like Acute Respiratory Distress Syndrome in well manner. In second wave there was again out break of covid-19 some regions of world. Here we discuss the causes of reoccurrence and their preventive measurements from our break effects of Covid-19.

This study was conducted to examine the soil fertility of the Büyük Menderes Basin, where wheat is widely cultivated. Soil samples were taken from 50 different points at a depth of 0-30 cm and various physical and chemical properties and amounts of nutrient elements were determined. With regard to the results of the study, the soils were generally sandy-clay-loam in texture, with slightly alkaline reaction, limy, rich in organic matter and showed no risk of salinity. The examined soils were found to be insufficient as 34% for total N, 14% for available K, 26% Mg, 10% Fe, 94% Zn and 98% Mn contents while all of the soils were determined as sufficient in terms of available P, Cu and Ca contents. When relationships between nutrient elements and soil physical-chemical properties were examined, negative correlations were found between soil pH and EC, organic matter, total N, available K, Zn; lime contents and available Mg, Fe, Cu; clay and available K and Mn contents. The positive correlations were found between EC and available K, Ca and Zn; organic matter % and total N, available K, Cu, Zn and Mn; sand % and available Mn; clay % and available Fe contents. Investigation of relationships between plant nutrients demonstrated that, there were positive correlations between total N and available K, Cu, Zn, Mn; available P and Zn; available K and Cu, Zn, Mn; available Ca and Fe; available Mg and Fe, Cu; available Fe and Cu, Mn; available Cu and Mn contents. The results of the study showed that attention should be paid to fertilization programs to fertilization with Zn and Mn, which were found to be insufficient in the greater part of the basin’s soils, and also to nitrogen deficiency is observed, as this directly affects the protein content of wheat.

Fermentation is known as a method that improves the nutritional value of foods in addition to preserving them. Various traditionally produced fermented foods such as yogurt, kefir, kombucha, some cheeses, sausages and pickles have probiotic potential. Hence, consumption of fermented foods plays an important role in modulating of gut microbiota and supplying positive effects on health. With the help of beneficial microorganisms, the intestinal barrier can be improved which induces the activity of the immune cells associated to the gut. In recent years, probiotics have been used in foods in order to produce functional foods that have the potential to improve gastrointestinal health. It is known that intestinal microbiota and probiotics can interact in immune system and these interactions provide positive health effects like reducing risk of hypertension, improving gut microbiota, regulating immune system, preventing diabetes, allergies and diarrhea. In this paper, fermented foods having probiotic potential and the effects of consuming these foods on the immune system are revised.

Iron (Fe) deficiency in plants is one of the widespread problems limiting agricultural production. Generating crops more tolerant to Fe deficiency by genetic engineering or breeding is of great interest but challenging due to the knowledge gaps in general plant Fe homeostasis. Although several genes involved in Fe homeostasis have been identified, characterization of their roles is mainly limited to specific organs at specific developmental stages of the plant, where their mutants show the most striking phenotype. Vacuolar Iron Transporter 1 (VIT1) is a well-known gene that has been characterized for its function in the mature seed of Arabidopsis thaliana. VIT1 is an Fe transporter that determines the correct distribution of Fe storage in this organ. The study aimed to explore new physiological functions for VIT1. As a first step, Arabidopsis thaliana plants that contain PromoterVIT1: GUS constructs were used to study the temporal and spatial expression of the gene throughout the plant’s lifecycle. GUS histochemical staining revealed the VIT1 promoter is active in the mature leaves and mature reproductive organs. VIT1 promoter activity in the stamen increased developmentally and was limited to tapetum and guard cells in the pollen sac. In the female organ, VIT1 promoter activity increased as the pistil developed into a silique. Although all the silique exhibited staining, staining density was higher in the peduncle, replum, and stigma regions. Inside the developing silique, funicles were heavily stained. Furthermore, in silico analyses of VT1 transcriptome and protein levels confirmed flower and the silique are hot spots for VT1 activity. Thus, the results may suggest a possible involvement of VT1 protein in several stages of the reproductive system, specifically in the flowering and in the fruit development.

In this study, the dynamism of forest areas was tried to be determined by determining the ecological differences between the areas where Fagus orientalis Lipsky. (Eastern beech, Fagaceae), a very important species for forestry in Turkey, and the soils of agricultural fields. lime %, total salt %, pH, texture, field capacity %, C%, N%, C/N ratios, 30-day carbon mineralization of the lands of Eastern beech forests and agricultural fields, which are naturally formed in Sivas province Koyulhisar district, under controlled conditions (28°C, 80 humidity %) was determined by the respiration method, and two areas in two different ecosystems were compared. When the carbon mineralizations of eastern beech soils were examined seasonally, it was determined as 19.54>18.23>17.87>17.18 mg C(CO2)/100g DS/30 day in spring>autumn>summer>winter seasons, while it was determined as 14.46>13.87>13.68>13.65 mg C(CO2)/100g DS/30 day in autumn>summer>spring>winter seasons in agricultural soils, respectively. Significant relationships were found between the C%, N%, 30-day carbon mineralization cumulative values and % carbon mineralization rates between both areas.

This study was conducted to investigate the effects of oak chips-supplementations on phenolic compound profiles of grape vinegar samples. Total acidity, volatile acids, non-volatile acids, pH, dry extract, ash, color, alcohol, total phenolic compound, individual phenolic compounds and aroma compounds of un supplemented control (UC) samples and oak chips-supplemented (OCS) samples were analyzed at the 0th, 1st and 3rd months of ageing. Total phenolic compound of UC vinegar samples was measured as 1256.50 mg GAE/L at the end of the 3rd month. Total phenolic compound of OCS vinegar samples was measured as 1521.03 mg GAE/L at the end of the 1st month and as 1470.67 mg GAE/L at the end of the 3rd month. Gallic acid, catechin and vanillic acid contents of UC vinegar samples were respectively measured as 8.43 mg/L, 22.26 mg/L and 1.78 mg/L at the end of the 3rd month. Gallic acid, catechin and vanillic acid contents of OCS vinegar samples were respectively measured as 19.12 mg/L, 17.98 mg/L and 2.58 mg/L at the end of the 3rd month. The 3-hydroxy-2-butanone, hexadecanoic acid methyl ester, 9,12-octadecadienoic acid methyl ester and 9-octadecanoic acid methyl ester quantities increased at the end of the 3rd month with oak chips-supplementation to ageing process. It was observed that oak chips-supplementation increased total phenolic compound and some individual phenolics of grape vinegar samples.

This study was carried out to investigate the effect of equi-protein replacement of soybean meal with groundnut cake on immune status, haematology and serum biochemical parameters of broiler chickens. A total of One hundred and twenty (120) Cobb’s day old chicks were randomly allocated to five (5) dietary treatments of three (3) replicates and eight (8) chicks per replicate in a completely randomized design. The Diet I was the control diet with 100% SBM as the major plant protein source while in other diets, SBM was replaced with 25, 50, 75 and 100% GNC in equi-protein basis and designated as Diets II, III, IV and V respectively. Feed and water were provided ad-libitum throughout the experimental period of 56 days. Newcastle disease (ND) vaccines were administered following a stipulated regime. At the end of the experiment two birds were randomly selected from each replicate and slaughtered. Blood and serum was collected for haematological analysis, serum bioassay and HA/HI tests to determine antibody titres against ND vaccines. All data collected were subjected to one-way analysis of variance using SPSS software package. Results showed that haematological parameters were significantly influenced by the dietary treatments in which birds fed 50% equi-protein replacement of SBM with GNC had better PCV, basophil, MCH and MCHC values compared to that of birds in the other dietary treatments. The antibody titres of experimental birds were not significantly different among treatment groups. The diet with 50% equi-protein replacement of SBM with GNC elicited the highest antibody titres of Log28 and Log210 after the 1st and 2nd ND vaccinations when compared to the other diets. The serum total protein, globulin, albumin, and glucose were significantly influenced by the dietary treatments. The present result indicate that 50% equi-protein replacement of SBM with GNC in diets is not detrimental to health status of broiler chickens.

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.

In this study effects of Pb and Pb+NTA mixtures on the activity of alkaline phosphatase (ALP) in the blood tissues of Oreochromis niloticus were investigated. The fish were exposed Pb (0.1 mg/L Pb ve 1.0 mg/L Pb) and Pb+NTA ((0.1 mg/L Pb+0.3 mg/L mixtures NTA ve 1.0 mg/L Pb+3.0 mg/L NTA) for 7 and 21 days. ALP activity in the blood tissue was determined by spectrophotometric methods. In both exposure concentrations ALP activity increase with increasing exposure periods. activity in the blood tissues of fish exposed to Pb for 7 and 21 days was lower when compared to those exposed to Pb+NTA: As a result, it is thought that the toxic effect of lead on O. niloticus on biochemical parameters is prevented by NTA.
