Lifelong Learning Tendencies of Prospective Teachers

Stunning developments in this era have brought different meanings in both educational conditions and time and space in education. Developing technologies have made education applicable everywhere. In other words, education has been taken outside of the known space (classic school walls). Individuals’ constant innovation has caused the development of the concept of “lifelong learning”, which is among the primary concepts in today’s educational studies. However, teachers play a key role in accepting and accurately perceiving this approach. Because approaches and tendencies of teachers concerning this subject will be effective upon forming a relevant perception in their environment. Education received by teachers in the preservice period plays an important role in the formation of a positive or a negative tendency. Thus, the determination of lifelong learning tendencies of prospective teachers is very important in terms of educational strategies to be developed in this direction. The objective of this study is to determine lifelong learning tendencies of prospective teachers according to different variables. Target population of the study consisted of students studying in different grades of Gazi University Gazi Faculty of Education. As the group where the study data would be collected was very intense; no sample was selected to represent the population. In this context, 350 students studying in different grades were included in the sample. In the study, the data were collected via a scale that was developed by Coskun Diker (2009). The collected data were analyzed and tabulated via the SPSS package software. Examining the data; it was observed that lifelong learning tendencies of prospective teachers differed according to gender, academic achievement, grade and the state of participating in a personal development course.

The effects of cadmium chloride on secondary metabolite production in Vitis vinifera cv. cell suspension cultures

BACKGROUND: Plant secondary metabolites are possess several biological activities such as anti-mutagenic, anti-carcinogenic, anti-aging, etc. Cell suspension culture is one of the most effective systems to produce secondary metabolites. It is possible to increase the phenolic compounds and tocopherols by using cell suspensions. Studies on tocopherols production by cell suspension cultures are seldom and generally focused on seed oil plants. Although fresh grape, grape seed, pomace and grape seed oil had tocopherols, with our best knowledge, there is no research on tocopherol accumulation in the grape cell suspension cultures. In this study, it was aimed to determine the effects of cadmium chloride treatments on secondary metabolite production in cell suspension cultures of grapevine. Cell suspensions initiated from callus belonging to petiole tissue was used as a plant material. Cadmium chloride was applied to cell suspension cultures in different concentration (1.0 mM and 1.5 mM) to enhance secondary metabolite (total phenolics, total flavanols, total flavonols, trans-resveratrol, and α-, β-, γ- δ-tocopherols) production. Cells were harvested at two days intervals until the 6th day of cultures. Amounts of total phenolics, total flavanols and total flavonols; trans-resveratrol and tocopherols (α-, β-, γ- and δ-tocopherols) and dry cell weights were determined in the harvested cells. RESULTS: Phenolic contents were significantly affected by the sampling time and cadmium concentrations. The highest values of total phenolic (168.82 mg/100 g), total flavanol (15.94 mg/100 g), total flavonol (14.73 mg/100 g) and trans-resveratrol (490.76 µg/100 g) were found in cells treated with 1.0 mM CdCl2 and harvested at day 2. Contents of tocopherols in the cells cultured in the presence of 1.0 mM CdCl2 gradually increased during the culture period and the highest values of α, β and γ tocopherols (145.61, 25.52 and 18.56 µg/100 g) were detected in the cell cultures collected at day 6. CONCLUSIONS: As a conclusion, secondary metabolite contents were increased by cadmium chloride application and sampling time, while dry cell weights was reduced by cadmium chloride treatments

Role of serum metalloproteinases 2 and 9 to assess the severity of COVID-19 in pregnant women: a prospective cross-sectional study

Objectives: To investigate the relationship between blood matrix metalloproteinases -2 and -9 levels and disease severity in pregnant women with COVID-19 infection. Material and methods: A prospective cohort study was conducted at the Kanuni Sultan Suleyman Education and Research Hospital in Istanbul, Turkey. We measured serum MMPs-2 and-9 levels of the healthy pregnant controls and pregnant women with COVID-19 and sought to assess the status of these MMPs in pregnant women with COVID-19, especially in women with a severe form of COVID-19 as diagnosed by abnormal computed tomography (CT) findings in addition to severe clinical and laboratory findings. Results: Of the healthy pregnant controls and pregnant women with COVID-19, the serum MMP-2 levels were comparable, but the MMP-9 level was lower in the pregnant women with COVID-19. Although the serum MMP2 level was somewhat lower in the women with COVID-19 with abnormal CT findings. The serum MMP-9 level of pregnant women with COVID-19 with abnormal CT was meaningfully lower. Conclusions: In the pregnant women, COVID-19 decreases the serum MMP-9 but does not change the serum MMP-2. COVID-19 with abnormal CT findings causes minimal decrease in the serum MMP-2 but decreases the serum MMP-9 with abnormal CT findings. Considering the study variables of current study, the probability of LMWH-related MMP alterations needs to be a study topic to clarify the possible contribution of LMWH to the status of serum MMPs in pregnant women with COVİD-19 especially in the women with COVID-19 with abnormal CT findings

The effect of a calisthenic exercise bout on oxidant and antioxidant status in middle-aged and postmenopausal women

Exercise increases the generation of oxygen free radicals and lipid peroxidation. The aim of this study was to investigate the oxidant and antioxidant status in sedentary middle-aged (36.8 +/- 5.4 years, n = 20) and postmenopausal women (51.4 +/- 3.3 years, n = 11) before and after acute calisthenic exercise. Both subject groups performed an acute calisthenic exercise for 55 minutes. The intensity of the exercise was 60-70% of maximal heart rate, as determined by Karvonen et al. Plasma malondialdehyde (MDA), gluathione (GSH), ascorbic acid (AA) and nitric oxide (NOx) levels were determined spectrophotometrically

Heparin Infusion to Prevent Umbilical Venous Catheter Related Thrombosis in Neonates

Objective: To investigate umbilical venous catheter (UVC) related thrombosis by Doppler echocardiographic evaluation of neonates infused with heparin or placebo

Detectability of microscopic findings of fracture healing in the early stages of the healing process at various postmortem intervals and evaluation of wound vitality

In our study, it is aimed how long do the microscopic findings of fracture healing in postmortem interval can be detected and whether the detected findings can be used in differentiation of fractures occur in the period of antemortem or postmortem or not. In our study, microscopic findings of 10 study groups included manually fractured bone samples that were created in antemortem period in New Zealand White rabbit fibulas. The specimens, in a closed environment under constant temperature and humidity that exposed to 15-day process of putrefaction, microscopic signs of inflammation, fibrin, granulation tissue and periosteal new bone formation in fracture edges were evaluated. In the control group, none of the evaluated parameters were detected microscopically. In microscopic evaluation of the study groups; fibrin was detected in the all study groups including postmortem 360th hour samples. As a result in our study; in bone fractures, inflammation findings, fibrin, granulation tissue and the presence of periosteal new bone formation, have indicated even in cases where advanced processes of autolysis and putrefaction or soft tissue has disappeared, it revealed significant findings in terms of vitality by histopathological examination.
