The impact of some animal products on agricultural gross domestic product in Türkiye: A time series analysis
(REVISTA BRASILEIRA ZOOTECNIA BRAZILIAN JOURNAL ANIMAL SCI, 2024) Acıbuca, Veysi
The relationship between animal products and agricultural gross domestic product (AGDP) in Turkiye was investigated in this study. We used data of eight animal products (cow milk, sheep milk, beef, mutton, poultry meat, eggs, wool, and honey) from 1980 to 2020. After checking the stationarity of the series by the Augmented Dickey-Fuller (ADF) test, the Johansen cointegration test was used to establish the existence of a long-term relationship between animal products and AGDP, and the results were interpreted using The Fully Modified Ordinary Least Squares (FMOLS) analysis. According to the findings, honey, beef, poultry meat, mutton, eggs, and wool had a positive and significant relationship with AGDP in Turkiye, whereas sheep milk and cow milk and AGDP was not significant. The total effect of the examined animal products on AGDP was 0.61%. The results showed that wool was the most important contributor to AGDP among the products analyzed. Therefore, it is suggested that policymakers develop funding strategies to expand the production of these products.
Comparison of growth factor levels in injectable platelet-rich fibrin obtained from healthy individuals and patients with chronic periodontitis: a pilot study
(Springer, 2024) Karcı, Bilge; Savaş, Hasan Basri
Background: This study aimed to assess and compare the concentrations of growth factors, white blood cells (WBCs), and platelets in injectable platelet-rich fibrin (i-PRF) derived from people with healthy periodontal conditions and those with chronic periodontitis.
Methods: Venous blood samples were obtained from 30 patients diagnosed with chronic periodontitis (test group) and 30 participants with healthy periodontal conditions (control group). The i-PRF was then acquired from centrifuged blood. The growth factors (VEGF, IGF-1, TGF-β1, PDGF-BB and EGF) released from the i-PRF samples were compared between groups with ELISA testing. The amounts of WBCs and platelets were also compared.
Results: No significant differences in the concentrations of growth factors were found between the groups (the mean values for the control and test groups were, respectively: IGF: 38.82, 42.46; PDGF: 414.25, 466.28; VEGF: 375.69, 412.18; TGF-β1: 21.50, 26.21; EGF: 138.62, 154.82). The test group exhibited a significantly higher WBC count than the control group (8.80 vs. 6.60, respectively). However, the platelet count did not show a statistically significant difference between the groups (control group 242.0 vs. test group 262.50). No significant correlation was observed between WBC count and growth factor level in either group.
Conclusions: The growth factor levels in i-PRFs did not exhibit significant difference between the two groups. This suggests that the levels of these growth factors may be unaffected by the periodontal disease.
Thirteen-year surveillance results of acute flaccid paralysis cases in Southeast Turkey and the effect of refugee movements on surveillance results
(National Institute of Public Health, 2024) Özgün, Nezir; Kubat, Gülnaz; Turan, Birgül; Özgün, Mert; Toktaş, İzzettin; Korukluoğlu, Gülay
Objective: Acute flaccid paralysis (AFP) is a major neurological problem. Turkey has accepted over 4 million refugees since 2011 due to the wars in neighbouring countries. In the long term, refugees can have adverse effects on the limited resources of health, sanitation, water supply, foodstuff, and shelter services of host countries, precipitating the transmission and spread of enteroviruses causing AFP. This study examines the 13-year surveillance and incidence of AFP cases in southeast Turkey, and questions possible impact of refugee movements on these parameters, comparing the periods before (2007-2010) and after (2011-2019) 2011, when the refugee movements emerged.
Methods: The records of cases reported from southeast part of Turkey with suspected AFP between January 2007 and December 2019 were reviewed retrospectively.
Results: Of the patients, 121 (58.5%) were male. Mean age was 80.36 ± 46.67 months. Eighty-five (41.1%) were aged 60 months or younger. The number of patients under 60 months increased significantly after 2011. Mean incidence was calculated as 0.88 cases/100,000 person years versus 1.58 cases/100,000 person years in the period before and after 2011, respectively. Guillain-Barré syndrome (GBS) was the most common cause of AFP in both periods. As of 2011, however, the incidence of acute transverse myelitis increased approximately 4 times and GBS decreased proportionally. Non-polio enteroviruses were the most frequent isolates, detected from 9.1% of stool samples.
Conclusion: Although refugee movements appear to may have adverse effects on AFP incidence and surveillance outcomes, larger studies involving the whole country, particularly at places where no refugees settled, are needed to achieve more conclusive evidence.
Community displacement challenges in educational tourism
(Routledge, 2024)
This study investigates issues relating to community displacement of the indigenous residents of Famagusta resulting in an increased rate of relocation to the suburbs due to the sudden growth of educational tourism; thus, the main objective of the current study is to obtain perspectives of learners on primary motives. An in-depth interview of 28 Cypriots in Famagusta, through purposive sampling was used to gather data for the current research. Findings reveal that the increase in educational tourism in Famagusta caused the indigenous Cypriots to move into suburban neighbourhoods. Factors including urbanization issues, social issues, economic issues, cultural issues, and environmental issues were revealed to be the most challenging issues resulting in community displacement.
Investigation of yield stability of wheat varieties in different locations by AMMI and GGE-biplot analysis
(Springer, 2024) Tiryakioğlu, Murat; Aktaş, Hüsnü; Akçalı, Cem Tufan; Şahin, Cenk Burak
The aim of the study was to determine the structure of GEI in the investigated parameters and to investigate the performance stability of durum wheat varieties using the GGE biplot and AMMI analysis method. The study was carried out in four different locations (Diyarbakır-1, Diyarbakır-2, Hatay, and Şanlıurfa) using 31 durum wheat genotypes under rainfed conditions. Field experiments were conducted in a randomized complete block design with three replications. As a result of the study, it was determined that there was a significant difference between locations in terms of grain yield. The highest grain yield was obtained from Diyarbakır-1 (6797 kg ha-1) location, followed by Hatay (4584 kg ha-1), Diyarbakır-2 (2512 kg ha-1) and Şanlıurfa (2026 kg ha-1), respectively. Significant variations in grain yield were detected among the examined genotypes, and Artuklu and Zühre had the highest grain yields (4774 and 4501 kg ha-1). Again, Artuklu and Zühre were the most stable varieties in terms of their performance in different locations. Diyarbakır-1 has come to the fore as the location where the variation between genotypes can be best detected. As a result, more data should be provided to plant breeders in the selection studies by considering the irrigated conditions as a factor in the studies to be carried out and determining the stable cultivars in terms of grain yield in both precipitation-based and irrigated conditions.
