Evaluation of post-earthquake late-term trauma levels in dialysis patients and healthcare professionals
No full textAim: To determine and compare the post-earthquake trauma levels of hemodialysis (HD) patients, healthcare professionals working in the HD unit, and peritoneal dialysis (PD) patients in the 11th month of two earthquakes that occurred approximately nine hours apart on February 6, 2023, and affected the east and southeast regions of Turkey. Materials and Methods: The study included a total of 162 individuals, including 87 HD and 35 PD patients who had experienced both earthquakes, and 40 healthcare professionals working in the HD unit. The post-earthquake trauma levels of the participants were assessed using the Scale That Determines the Level of the Trauma After the Earthquake (SDLTAE), consisting of a total of 20 items, developed by Tanhan et al. after the 2011 Van earthquake. The individuals with an SDLTAE score of >52 were considered highly traumatized. Results: The mean age of the participants was 53±16 years, and 79 (49%) were women. The SDLTAE score of the HD patients was found to be higher than that of the PD patients (p=0.006). There were no significant differences between the SDLTAE scores of the healthcare professionals and the HD and PD patients (p=0.419 and p=0.089, respectively). Upon comparing patients with low and high total SDLTAE scores, we observed that the rate of female individuals was higher in all groups (p0.05). Conclusion: We found that HD patients had a higher level of trauma than PD patients. Our study showed that women were more traumatized than men in sensitive groups, such as those receiving dialysis and healthcare professionals. Regularly conducting psychological assessments for dialysis patients and healthcare professionals may increase the likelihood of early intervention
Karşı Ticaretin Özellikleri, Dış Ticaret Açığını Azaltmadaki Yeri ve Türkiye’de Uygulama Alanı
No full textAmaç: Bu çalışmanın amacı Türkiye’de kronik hale gelen dış ticaret açığının azaltılmasını sağlayacak önemli yollardan biri olan karşı ticareti ve özelliklerini inceleyerek, son on yıl içinde karşı ticaretin Türkiye’deki gelişimini ve Türkiye’nin dış ticareti içindeki yerini irdelemektir. Tasarım/Yöntem: Araştırmada TÜİK’in 2014-2023 yılları arasındaki son 10 yıllık verileri kullanılarak karşı ticaretin Türkiye’nin dış ticareti içindeki yeri belirlenmeye çalışılmıştır. Bulgular: Yapılan incelemler neticesinde TÜİK’in verileri incelendiğinde Türkiye’de son on yıl içinde ihracatın ithalatı karşılama ortalamasının %73,8 olduğu görülmektedir. Yani, her 100 USD’lik ithalat için 73.8 USD ihracat bedeli ödenirken, kalan 26.2 USD’lik kısım Merkez Bankasının kısıtlı olan kaynaklarından karşılanmaktadır. Bu noktada özellikle petrol ve petrol ürünlerinin satın alındığı komşu ülkelerle karşı ticaretin artırılması ve bu yolla ülkeden döviz çıkışının önüne geçilmesi, ileriye yönelik atılması gereken önemli adımlardan biridir. Sınırlılıklar: Türkiye’nin dış ticaretinde kullnaıln ödeme sistemlerinin geriye yönelik araştırmasında detaylı verilerin çok daha fazla yıla yayılamaması araştırımın sınırlılıklarıdır. Özgünlük/Değer: Yapılan literatür taramasında karşı ticaretle ilgili sınırlı çalışmaların yapıldığı görülmekle beraber bu çalışmaların daha çok 1980-1990’lı yıllarda yapıldığı ve bu çalışmalarda karşı ticaretin genel yapısının incelendiği, karşı ticaretin dış ticaret açığını azaltmadaki rolüne değinilmediği görülmektedir. Bu çalışmada, karşı ticaret bu açıdan değerlendirilerek, karşı ticaretin dış ticaret açığını azaltmadaki rolü araştırılmıştır

Real-Time RT-PCR analysis was used to investigate the presence of Cherry leaf roll nepovirus (CLRV), Plum pox potyvirus (PPV), Peach latent mosaic pelamoviroid (PLMVd), and Hop stunt hostuviroid (HSVd) in the collected pistachio samples and Pistacia emaravirus B (PiVB) in the walnut samples. Real-Time RT-PCR tests revealed that of 649 pistachio samples, 14.7% had HSVd and 5.4% had PLMVd infection. Furthermore, mixed infections of PLMVd and HSVd were present in 0.9% of the samples. PiVB was not detected in any of the tested samples. Among the 230 walnut samples examined, 11.3% had HSVd, 12.6% had PPV, 42.2% had CLRV, and 5.7% had PLMVd. Additionally, 7.8% of the samples had PPV+CLRV, 1.3% had PPV+HSVd, and 0.4% had mixed infections with PPV+PLMVd, 1.3% had HSVd+PLMVd, 2.2% had HSVd+CLRV, 2.2% had PLMVd+CLRV, and 0.4% had HSVd+CLRV+PLMVd factors. Molecular characterization studies were carried out by randomly cloning one PLMVd, HSVd, CLRV, and PPV isolate from the isolates detected as single infections in each province. Nucleic acid sequences from the isolates revealed similarities with other isolates found worldwide, with rates ranging from 89.5–100% for HSVd isolates, 87.1–98.6% for CLRV isolates, and 91.4–99.3% for PPV isolates. These similarities were found in the isolates from which nucleic acid sequences were obtained. This study reports the first-ever detection of PLMVd in pistachios and HSVd in walnuts. Molecular evidence for PPV was discovered in walnuts for the first time ever

In the process of data analysis, document analysis method was used. Within the scope of the research, previous academic studies, articles and reports on financial sustainability, football economics, European Football Associations Association practices and financial management of football clubs were analysed. In addition, official documents such as sector reports and Financial Fair Play reports that address the financial situation and financial performance of football clubs were utilised. It has been determined that revenue diversification, budget management and financial discipline strengthen the financial stability of clubs and provide competitive advantage. Infrastructure investments and digital financial instruments are found to contribute to long-term success by reducing the costs of clubs. Regulations such as Financial Fair Play are critical for maintaining the economic stability of clubs and attracting investors. In addition, strategic partnerships and investor support have been found to strengthen the financial sustainability of clubs and increase competitiveness in the international market. As a result, a comprehensive budget management and financial discipline are required to ensure the financial sustainability of football clubs. However, strategic partnerships and digital financial tools contribute to long-term success by increasing the clubs’ international competitiveness and economic stability
Sandfly Fever-Related Acute Hepatitis Outbreak After Kahramanmaraş Earthquake
No full textIntroduction: Sandfly fever virus, a member of the Phlebovirus (Bunyaviridae family), can cause sandfly fever, also known as “Pappataci fever”. This vector-related disease occurs primarily in endemic regions during the summer months. Epidemics may develop in different regions if favorable environmental conditions and vector transport are present. Laboratory changes, such as elevated transaminases and creatine kinase levels, leukopenia, and thrombocytopenia, may be observed in sandfly fever. In this study, we aimed to evaluate the laboratory results and progression of sandfly fever cases, which were concentrated in the conditions developing in the earthquakeaffected region. Materials and Methods: Seventeen sandfly fever cases who were followed up in our clinic between August and October 2023 were included in the study. These cases were patients who presented with non-specific complaints related to infection in the earthquakeaffected area after the February 6 Kahramanmaraş earthquake and had acute hepatitis with elevated transaminases, creatine kinase, and C-reactive protein (CRP). The study retrospectively evaluated the laboratory results and findings of cases positive for the sandfly fever virus. Results: Of the cases, 58.8% were male (n= 10), 41.2% were female (n= 7), with a mean age of 40.88 ± 19.59. The mean aspartate aminotransferase (AST) was calculated as 325.53 U/L, alanine aminotransferase (ALT) as 311.88 ± 282.36 U/L, alkaline phosphatase (ALP) as 109.64 ± 49.59 U/L, gamma-glutamyl transferase (GGT) as 80.82 ± 71.05 U/L, lactate dehydrogenase (LDH) as 564.47 ± 404.57 IU/L and creatine kinase (CK) as 872.38 U/L. Of the 17 cases, nine had leukopenia (53%), nine had neutropenia (53%), and five had lymphopenia (29.4%). Thrombocytopenia was observed in seven cases (41.1%). The mean CRP level was high at 3.78 mg/dL. Acute renal failure was also present in three cases. The cases were discharged after supportive treatment and observation, with improvements in both clinical and laboratory findings. Conclusion: Our study showed that sandfly virus-related epidemics may occur, particularly during warm months, when suitable conditions develop, such as after an earthquake. Additionally, it was determined that an acute hepatitis presentation, characterized by a significant increase in transaminases and creatine kinase, can be observed in sandfly virus infection. Our study also indicates that caution should be exercised regarding the potential for larger and more serious epidemics that may affect the region, especially during the summer months, if current conditions persist
Rethinking of Government Institutions and Governance Quality Indicators on Economic Growth in Sub-Saharan African Countries
No full textThe study aims to investigate the effect of governance quality on economic growth and government consumption in Sub-Saharan African countries. Balanced dynamic panel data for 36 Sub-Saharan African countries from 2011 to 2022 were analyzed using GMM and Driscoll-Kraay regressions. In addition to the fact that there is no study in the literature that examines the effect of state governance indicators on economic growth in SSA countries, the addition of government consumption variable as a second dependent variable adds originality to the study. The empirical analysis revealed that government institutions have a positive effect and are significant in SSA countries' economic growth. In addition, according to the Driscoll-Kraay regression, it is seen that governments' development of institutions increases government consumptions. The governance indicators threshold that strengthens the government institution in Sub-Sahara Africa must be reached to increase the economic growth of Sub-Sahara Africa. For economic growth, effective government institutions and governance quality policies should be practiced and maintained among the Sub-Saharan African countries
A RESEARCH ON ELECTRODE APPLICATIONS: SYNTHESIS OF NICKEL-DOPED GRAPHENE OXIDE
No full textIn today's technology, carbon-based materials (such as graphene, graphene oxide, carbon nanotubes, etc.) have become one of the most important research areas due to a large number of applications. Graphene oxide (GO) is being investigated in many applications, especially in the energy field. In this study, GO was synthesized by a modified Hummer’s method. After the synthesis of GO, nickel addition to the struc-ture was made by the hydrothermal method. The morphological and structural prop-erties of the synthesized GO were characterized by scanning electron microscope (SEM), X-ray powder diffraction (XRD) and Brunauer–Emmett–Teller (BET). Ac-cording to the BET results, the surface areas of untreated GO and Ni-doped graphene oxide after heat treatment at 360°C (Ni-doped GO 360) were calculated as 3.22 m2 g-1 and 228 m2 g-1, respectively. Electrochemical properties of GO and Ni-doped GO 360 were analyzed using cyclic voltammetry (CV), long term charge/discharge analysis and impedance spectroscopy. At the end of 1000 cycles, it was determined that the Ni-doped GO 360 electrode retained 76% of its initial capacitance

Weeds in the cotton growing areas in the Southeastern Anatolia Region
No full textThe Southeast Anatolia Region plays an important role, as it accounts for around sixty percent of Türkiye's cotton production. One of the most important factors limiting cotton cultivation is weeds. The aim of this study was to determine the weed species, their frequency and population density in the cotton growing areas of the Southeast Anatolia region. For this purpose, surveys were conducted in 152 cotton growing areas in Diyarbakır, Mardin and Şanlıurfa provinces in 2020 and 2021. The surveys were conducted using the segmented sampling method. As a result of the studies, 43 weed species belonging to 16 families were identified. When the weed species found in cotton are evaluated by family, the Poaceae family ranks first with 7 species, followed by Asteraceae with 6 species, Euphorbiaceae and Amaranthaceae with 5 species. redroot pigweed (Amaranthus retroflexus L.), field bindweed (Convolvulus arvensis L.), purple nutsedge (Cyperus rotundus L.), jungle rice (Echinochloa colonum (L.) Link), ground cherry (Physalis spp.), common purslane (Portulaca oleracea L.), black night shade (Solanum nigrum L.), johnson grass [Sorghum halepense (L.). Pers] and common cocklebur (Xanthium strumarium L.) were identified as the most common weed species. These weeds are widespread in many summer crops, especially in cotton. The development of effective management methods against these weeds in cotton will contribute to higher yields
