Mónika Kovács, Mária Szenes, Tihamér Horváth, Gy?rgy Vajda, Beáta Gasztonyi, Gy?rgy Bártfai
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.42014

AIM: The authors have aimed at confirming or excluding gluten sensitivity in infertile couples. PATIENTS AND METHODS: Between 2004 and 2010, at our outpatient clinics of immunology, both partners of 223 couples, who had striven for having a child unsuccessfully, underwent history taking, physical examination, laboratory and immuno-serologic tests including anti-tissue-transglutaminase antibody (antitTG), as well as deep duodenal biopsy in antibody-carrying patients. RESULTS: Antibodies against tissue transglutaminase were positive in 6/223 female patients of whom the diagnosis of celiac disease was histologically confirmed in 3/223 cases (1.34%). Of the male patients 2/223 (0.9%) have proven to be carriers of the antibody; histology was pathognomonic in both of them. Curiously, one of the male patients with celiac disease has been the partner of a woman who also had celiac disease diagnosed by the authors. In the followup period, a female patient and the female member of the couple with celiac disease gave birth to healthy newborns after spontaneous conception, as the result of a strictly kept gluten-free diet, as well as occasional treatments of acetylsalicylate for antiphos-pholipid syndrome or levothyroxine for latent hypothyroidism due to autoimmune thyroiditis. CONCLUSION: The results underline that it is worth performing a screening for celiac disease in both partners of couples assessed due to the lack of success in having a child, as infertility can be ceased by an appropriate diet.

The purpose of this study is to uncover the perceptions of the elementary school teacher candidates who have related to the concept of “drama” through metaphors. The study group consisted of 129 third-year students taking the “Drama” course during the fall semester of the 2012-2013 academic year in the Department of Elementary School Teaching of Necmettin Erbakan University’s Faculty of Education. 66 of the teacher candidates, who participated in the study, were females and the 63 of them were males. The data of the study was obtained by students completing the sentence of “Drama is like… because…”. To do this, the teacher candidates were given a blank sheet of paper with the aforementioned sentence written at the top of the paper and were asked to express their thoughts by using that statement and by concentrating on only one metaphor. During the analysis of the data, frequency, percentage calculations and content analysis which is a qualitative method, were used. The process of analyzing and interpreting the metaphors developed by the teacher candidates was carried in five phases: (1) naming stage, (2) screening and clarifying phase, (3) compiling and category development phase, (4) proving the validity and reliability phase, (5) transferring the data into the computer. According to the findings of the study, the teacher candidates developed 30 valid metaphors related to the concept of “Drama”. These metaphors were then grouped under five different conceptual categories after examining them in terms of common characteristics.

The purpose of this study was twofold: first to investigate the effect of conceptual change oriented instruction accompanied by concept cartoon worksheet with simulation on students’ conceptual understanding and second to remedy their misconceptions of direct current electric circuits. Participants were 139 pre-service science teachers from four intact classes. A quasi-experimental design was used in the study. The experimental group studied the concept with the application of concept cartoon worksheet and simulation, and the control group studied it with traditional instruction. Students’ conceptual understanding and misconceptions were measured by a tree-tired misconception test. It was administered as pre-and-posttest. There was no significant difference between the means of pre-test scores of experimental and control groups. The main effect of treatment on post-test scores was examined via ANCOVA with pre-test scores used as covariate. The frequency of each misconception was calculated for both groups, from pre to post-tests regarding all tiers of items. The analysis yielded a significant treatment effect on students’ post-test performances. The findings indicated that the conceptual change oriented instruction accompanied by concept cartoon worksheet and simulation is likely to be effective for conceptual understanding and decreasing most of students’ misconceptions in direct current electric circuits.

Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.41007

The direct link between smoking, lung diseases, cancer, cardiovascular disease and poor pregnancy outcomes, such as miscarriage and low birth weight, has been extensively studied. In the past three decades, there has also been an increasing awareness of the impact of smoking on periodontal disease. Smoking is considered the major environmental risk factor in the prevalence, extent and severity of periodontal disease. This review article will attempt to build on previous studies in the periodontal literature in order to present an evidence-based comprehensive literature review on the effects of smoking on periodontal disease.

Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.43022
Abstract: The positive relationship between smoking and major general health diseases such as cancer, cardiovascular disease, pulmonary disease and negative pregnancy outcomes is already established. Moreover, the association between smoking as a major environmental risk factor for periodontal disease has also been established. Smoking is considered to have negative adverse effect on periodontal therapy ranging from non-surgical treatment, periodontal surgery, regenerative procedures and implants. This review article will attempt to build on previous studies in the periodontal literature in order to present an evidence-based comprehensive literature review on the effects of smoking on periodontal therapy.
Some Biological Features of Aphtona whitfieldi Bryant (Coleoptera: Chrysomelidae), an Insect Pest of Jatropha curcas L. in Burkina Faso  [PDF]

Advances in Entomology (AE) , 2016, DOI: 10.4236/ae.2016.44024
Abstract: Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is a major insect pest of Jatropha curcas L. (Euphorbiacae) in Burkina Faso and other countries in West Africa. The insect pest feeds on the roots and the leaves of the plant. When the attacks are heavy, the plant may lose all its leaves and die off. Unfortunately, little information is available on the biology of this insect pest. A study was conducted on the biology of this insect pest in the Sissili province, South Burkina Faso and resulted in the knowledge of some of the biological features of the insect pest. Aphthona whitfieldi was reared from 13th July to 22th October 2015. Larvae and pupae were collected in J. curcas plantations near Léo, the capital city of the Sissili province, and brought to the laboratory for rearing. The insects were observed daily and the dimensions and the duration of each stage were recorded. We recorded two larval stages (1st and 3rd): a pre-pupa and a pupal stage. The pupa was free and white milk-like. Both the pre-pupa and the pupal stages lasted for five days. The 1st instar larva was smaller than the third one.
The Effect of Aphthona whitfieldi (Coleoptera: Chrysomelidae) Populations’ Density on the Growth of Jatropha curcas in Burkina Faso  [PDF]

Advances in Entomology (AE) , 2017, DOI: 10.4236/ae.2017.54013
Abstract: Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is a major insect pest of Jatropha curcas L. in Burkina Faso. This study aimed at evaluating the effect of the insect pest populations’ density on the growth of the plant. To achieve this purpose, 90-day aged single plants were caged in a randomized complete block design experiment with 5 treatments and 5 replicates. The treatments consisted of increasing numbers of adults of A. whitfieldi used to infest the caged plants: T0 (0 adult = check), T1 (100 adults), T2 (200 adults), T3 (300 adults), T4 (400 adults). All caged plants were infested 21 days after transplantation and the evaluation started 14 days later one on every 2-week basis from September 18, 2014 to February 19, 2015. The growth parameters of the plant were assessed. The results showed that the intensity of damage caused by A. whitfieldi on the growth of young plants of J. curcas varied according to the treatment (i.e., according to the number of adult individuals infesting the plant at the beginning). The higher the number, the heavier the level of damage caused by the pest. So, the growth of the J. curcas plant was inversely proportional to the number of A. whitfieldi infesting individuals. There was also a positive linear correlation between the defoliation rate and the height of the seedlings. The status of this insect pest was confirmed by the results of this study.

African Health Sciences , 2012,
Abstract: Objective: To determine the incidence of eclampsia and examine the maternal and fetal outcome. Methods: A hundred and twenty consecutive admissions with eclampsia managed in Aminu Kano Teaching Hospital, Kano, Nigeria, were prospectively collated and analysed. Maternal and fetal morbidity and mortality were recorded. Results: The incidence of eclampsia was 1.2% of deliveries. Most (69.2%) of the patients had no antenatal care. In 93 (77.5%), the convulsions were controlled with diazepam, and 22.5% magnesium sulphate. Maternal complications rate was 39.2%, and use of Diazepam for control of convulsions increases complications (RR 3.12, 95% CI = 1.23-7.92, p= 0.02). Case fatality rate was 11.7%, diazepam use failed to achieve significant association with maternal death (RR 8.64, 95% CI = 0.53-140.29, p= 0.13). Stillbirth rate was 22.5% with significant association with diazepam use (RR 7.55, 95% CI= 1.07-53.09, p=0.04). Birth asphyxia was recorded in 39.1% and low birth weight in 25.8%. Conclusion: The incidence of eclampsia in our hospital was very high, with corresponding high maternal and perinatal morbidity and mortality. Increased antenatal screening and use of magnesium sulphate to control convulsions will reduce the incidence and associated morbidity and mortality for both mother and fetus.
Challenges of sustainable rural tourism development in KwaZulu-Natal

Inkanyiso: Journal of Humanities and Social Sciences , 2010,
Abstract: Tourism has emerged as one of the strategic instruments and policy tools for community and regional development in Southern Africa (Rogerson, 2007 in Saarinen, et al. 2009). Gradually, tourism is rotating to the political centre stage as an instrument of social and economic empowerment (Binns & Nel, 2002). Consequently, local government authorities have instituted initiatives for promoting tourism as a sustainable economic driver in their municipalities. Sustainable rural tourism development is widely supported because it does not threaten the integrity of the ecological and social systems upon which communities and societies are dependent. Marien & Pizam in Wahab & Pigram (2004:165) argue that since communities are constantly changing, like the nature of tourism, evaluating community’s sensitivity and associated impacts should not be regarded as an temporary event but as an ongoing process. This study focuses on the strategic development of sustainable rural tourism in the rural areas of KwaZulu-Natal, more specifically Ntambanana Municipality. The objectives of the study were as follows: (a) To identify natural and sociocultural resources that can be used for rural tourism development. (b) To assess the participation level of local communities in tourism development. (c) To establish the extent to which the tourism policies and strategies are implemented. (d) To identify the capacity of the local communities to develop tourism products. (e) To reveal the challenges that impede sustainable rural tourism development. Data from a sample size of 320 were collected and analysed using the SPSS programme. The findings of the study indicated that there is potential for natural, cultural and heritage tourism due to the existence of a variety of related resources. The findings, however, indicated that local people are not aware of these resources hence the lack of participation in tourism development. Various strategies were suggested for raising social awareness and the promotion of cultural and heritage resources in the rural area.
