Sahin, Huseyin; Can, Zehra; Gürgen, Ayşenur; Kara, Yakup
Bee pollen plays a significant role in bee nutrition, bee population sustainability, pollination processes, and its health and nutritional benefits for humans. It contains protein, vitamins, minerals, and antioxidants, offering valuable nutritional properties. The total phenolic content (TPC) is an important parameter in determining the nutritional and health value of pollen. The presence of high levels of phenolic compounds in pollen enhances their health benefits and can provide protective effects against diseases by combating oxidative stress. In the study, ultrasonic extraction conditions for pollen were optimized using the Response Surface Method to maximize TPC. The experimental study was designed according to Box-Behnken design: 30–70% ethanol ratio, 5–15 min of extraction time, and 10–20% ultrasonic amplitude modulation (AM). The TPC of the obtained extracts were determined using the Folin-Ciocalteu procedure. The optimal extraction conditions were predicted as 60.012% ethanol ratio, 11.054 min, and 19.160% AM for reaching 9.572 mg/GAE g extract.

لما نزلَ القرآن الكريم على رسول الله ﷺ، احتاج بعض الصحابة الكرام، إلى تفسير بعض آياته الكريمة التي صَعُبَ عليهم فهمها، ولذلك أخذ رسول الله ﷺ على عاتقه تفسير هذه الآيات، فبيّن لهم ما أُشكِل عليهم؛ فلما توفي رسول الله ﷺ اهتم بعض الصحابة بتفسيرها وبيان معانيها وألفاظها؛ ومع توسُّعهم وانتشارهم في الأمصار، نشأت في كلّ بلدٍ مدرسة للتفسير؛ فكان ابن عبّاس في مكّة، وأبيُّ بن كعب في المدينة، وعبد الله بن مسعود في الكوفة، ثم كثرت مدارس التفسير، وكثرت اتجاهاته ومناهجه، في كل الدول الإسلامية. وفي العصر الحديث ظهرت نزعات تفسيريّة جديدة؛ نتيجة لتطور العلوم، حيث ظهرت النزعة العِلميّة في تفسير القرآن، والبحث عن أوجه الإعجاز فيه. ولما كان العصر الحديث هو عصر العلم والتكنولوجيا، فقد ظهر كثير من المفكرين والعلماء، الذين أخذوا في الربط بين العلم وتطوراته، وبين القرآن الكريم، وردوا كل شيء إليه. ولذلك تنوعت كتب التفسير في مصر في القرن العشرين وكثرت، واشتهر كثيرون. وقد اتسمت هذه التفاسير بالسهولة والأسلوب الأدبي البلاغي، حيث طبيعة العصر الذي يحتاج إلى السهولة، ليصل إلى شريحة أكبر؛ ولذلك فإننا نتناول جهود هؤلاء العلماء في خدمة القرآن الكريم، ومناهجهم في تفسيره. وكان من أهم الصعوبات التي واجهت الباحث في هذا البحث هو ذلك الكم الهائل من المفسرين والمفكرين ومؤلفاتهم التي تركوها لنا في كل الاتجاهات المتنوعة والمختلفة، ولكنها تتفق جميعًا حول إعلاء كلمة الله تعالى، وفهم نصوصه الكريمة، وتقريبها إلى الأذهان والأفهام.

Kaya, Fatih
This research aims to examine the opinions of teacher candidates about the DKAB-OABT applied since 2013 and the IHL-OABT exams that have started to be held since 2018. The research was carried out with the case study method, one of the qualitative research designs. The study group of the research consisted of 25 teacher candidates who graduated from various faculties of theology and who took the OABT exam at least twice, determined by the purposive sampling method. In this context, the data of the research were obtained through a semi-structured interview with 3 open-ended questions. In the analysis of the data, themes were created using content analysis. It has been concluded that during the preparation process for the OABT exam, the most frequently used resources by teacher candidates are OABT lecture books, digital content, OABT question banks and trial exams. It has been determined that the majority of the participants are of the opinion that the education given in the undergraduate level is "adequate" in preparation for the exam, since the theology education at the undergraduate level is qualified and the course content is comprehensive. However, it was determined that the participants found the content validity of the OABT sufficient and stated that the OABT questions coincided with the undergraduate education of theology, covered most of the compulsory courses, and the question distribution was suitable for the courses explained in the exam content by OSYM. In addition, it was concluded that the majority of the teacher candidates were of the opinion that the OABT exam should be done in a single session, since the subject and question distribution of the OABT questions were close and the exams were similar.

Boz, Ediz; Türk, Ersin; Togan, Vedat
The construction of the railway, which is needed for the development of the Eastern Black Sea Region, is an issue that has been discussed and unresolved for about 110 years. The geomorphological structure of the region and the developments in the highway played a role in the delay of the railway construction. However, the developing technology in the railway, Turkey's being a part of the Iron Silk Road Project, and the agreements made with international connections have brought the railway construction to the region again. In the Environmental Plan (EP) approved and in force by the Ministry of Environment, Urbanization and Climate Change, four railway routes are planned to integrate the Eastern Black Sea region with the national/international railway network. These routes are; Samsun-Sarp, Trabzon-Erzincan, Of -Erzurum and Tirebolu-Bayburt. However, some of these routes are alternatives to each other and are not feasible and rational since the implementation of all planned routes requires great costs. The aim of this study is to develop a method for prioritizing and selecting the railway routes planned in the EP. Within the scope of this purpose, by using Analytical Hierarchy Process (AHP) and TOPSIS techniques, which are multi-criteria decision making methods, the routes were listed according to 4 criteria and 10 sub-criteria determined with the help of literature and expert team. As a result of the study; In both techniques, the order was the same and it was determined that the Samsun-Sarp railway was the most priority railway route. Trabzon-Erzincan came second, Of-Erzurum came third and Tirebolu-Bayburt came fourth.

Purpose: Type 2 diabetes mellitus (T2DM) is a heterogeneous, chronic, and metabolic disease that affects a significant proportion of the global population. This study aimed to evaluate the effect of NFKB1-94 ATTG ins/del polymorphisms on the expression of apoptosis genes and telomere length (TL) in patients with T2DM compared with healthy individuals.Materials and Methods: Sixty-nine T2DM patients and sixty healthy people were enrolled in the study. DNA and RNA were isolated from the blood samples. NFKB1 genotypes were identified by Sanger sequencing. For TL analyses and to investigate the expression of the caspase-3, caspase-9, bax, and bcl2 genes, RT-PCR was utilized.Results: There was a significant difference between the NFKB1-94 ins/del genotype patients and the control group (OR:0.4792 (0.2345-1.011)). However, the distribution of other genotype/alleles (ins/ins and del/del) showed no difference between T2DM and control groups. The allelic frequency of NFKB1-94 ins/del was 0.455/0.235 for the T2DM group and 0.435/0.165 for the control group. An increase in the mRNA expression of caspase-3, caspase-9 and Bax genes was observed in the T2DM group compared with the healthy group, while a decrease in the Bcl2 gene was found in the T2DM group. TL in T2DM patients was shorter than in healthy individuals.Conclusion: NFKB1-94 ins/del polymorphisms show significant differences in T2DM patients. We observed that apoptosis was activated and TL was shortened in patients with T2DM. However, no relationship between NFKB1 polymorphisms and apoptosis and TL could not be determined.

This study was aimed to (1) investigate the failure surface mechanism occurring behind the wall supporting narrow backfill with experimental and numerical approaches; (2) determine the effect of internal friction angle (phi), friction (delta), heel length (beta), foundation thickness (alpha), backfill inclination (psi), and backfill width (theta) parameters on lateral earth thrust coefficients; and (3) derive finite-element analysis (FEM)-response surface method (RSM)-based lateral earth thrust coefficient equations for inverted T-type retaining walls supporting narrow backfill. The study was performed for granular backfill. A small-scale test was performed to investigate the failure surface mechanism in the narrow granular backfill. The particle image velocimetry method was employed to determine failure surface patterns for various heel lengths and backfill widths. Finite-element (FE) analyses were also performed to verify the experimental results. From the analyses, it was seen that two characteristic soil blocks formed behind the horizontally translated wall. Due to these soil blocks, the wall was divided into three characteristic regions. Lateral active earth thrust coefficients were derived for the regions. RSM was employed to derive FE-based lateral earth thrust coefficient estimation equations for each region. In this context, three design matrices were created, comprising 76 runs. In the design, parameters phi, delta, beta, alpha, psi, and theta were used as independent variables. A total of 76 FE analyses were performed for various parameter combinations. The results of the FE analyses were used as a response. From the statistical analyses, lateral active earth thrust estimation equations for narrow backfill were derived. The suggested equations were compared with the results of experimental, numerical, and analytical studies, and it was seen that the method gives reliable results. The effects of independent variables and their interactions on lateral earth pressure coefficients were examined.

Uzunçakmak, Sevgi Karabulut; Sahin, Abdulkadir; Özçelik, Aysegul Tavaci; Halici, Zekai
Purpose: Nasal polyps (NPs), usually occurring together with chronic rhinosinusitis (CRS), are benign masses of mucosal origin arising from inflammation. The transmembrane protein known as leucine-rich repeats and immunoglobulin-like domains 1 (Lrig1) is a member of the Lrig family. Lrig1 is frequently expressed in the respiratory tract and epithelial tissues and can inhibit several signaling pathways involved in cell proliferation. The aim of this study was to determine Lrig1 levels in NP tissues of patients with CRS. Material and Methods: This study included 36 patients with CRS and NPs and 15 patients who underwent rhinoplasty as the control group. The Lrig1 levels of all participants were measured by the ELISA method.Results: This study revealed that Lrig1 levels were significantly lower in NP tissues than in tissues of the control group. The mean level of Lrig1 of the NP tissues was 22.2 ng/ml, while the mean level of the control group was 28.5 ng/ml. According to the results of ROC analysis, Lrig1 levels have the power to distinguish polyp tissues from control tissues (AUC=0.794). Lrig1 levels were higher in tissues with scores of 4-8 than in tissues with scores of 16-20 based on the results of computed tomography scoring. According to endoscopic evaluations, Lrig1 levels of tissues with scores of 5-8 or 9-11 were relatively lower than those of tissues with scores of 2-4.Conclusion: Lrig1 levels were found to be decreased in NP tissues. Thus, Lrig1 may be used to confirm the presence of NPs. Lrig1 may also be helpful in NP grading. Increasing the Lrig1 levels in cases of NPs has the potential to become a targetable treatment modality.

This study seeks to determine the role of cynicism in the relationship between the perceived spiritual leadership of university employees and their organizational commitment. Because of the international nature of the problem at hand-university staff in Turkey and Indonesia who are engaged in ongoing educational activities-a comparison strategy predicated on cultural differences was favored. The study utilized correlation analysis and normal distribution determination in SPSS, and structural equation modeling in AMOS to reveal regression relations. Findings suggest that academics in Turkey and Indonesia are more committed to their institutions when they have a positive perception of the organization's spiritual leadership. Likewise, when university employees perceive cynicism in the organization, their commitment to spiritual leadership and the organization reduces. In other words, cynicism appears to partially mediate the relationship between spiritual leadership perception and organizational commitment in both countries.

Inal, Ibrahim Hakki; Sever, Mehmet
Wahhabism, which emerged in the mid-18th century, is a movement that draws attention with its reactivity in Islamic thought. The views of its founder, Muhammad b. 'Abd al-Wahhab, were built to deny the centuries-old religious understanding of the Muslim community, based on a bida'-centered thought. In this direction, Wahhabism has transformed the elimination of institutions and structures that it regards as signs of disbelief into a structural character. This study examines the critical treatise on Wahhabism by the Iraqi poet Jamil Sidqi al-Zahawi (d. 1936), who was disturbed by its activities in Iraq. Zahawi wrote al-Fajr al-Sadiq to reveal the historical origins of Wahhabism and criticise its political and religious activities, and tried to explain the unknown aspects of this religious movement. The work, in terms of its content, has examined the issues that occupy the agenda of Muslim society such as shirk (polytheism), bida' (heretical innovation), tawassul (request), and takfir (excommunication). The work, which is a refutation, draws attention as an important source in scholarly studies on Wahha-bism in terms of its content. In this study, the theoretical and historical criticism put forward by Zahawi will be tried to be revealed by using the textual analysis method. According to Zahawi, Wahhabism is a movement instrumentalised for political rather than religious pur-poses. The sociological basis of this structure, which is based on Kharijite thought, is based on tribalism and contains reactionism against the other.

This study aimed to determine the yield and yield components and quality features (oil ratio and fatty acid composition according to GC-MS) of six different tarragon (Artemisia dracunculus L.) local breeds grown organically in Bayburt province, Turkey. For this purpose, the data obtained by growing the plants in the experimental area during the two crop years, 2018 and 2019, were evaluated. As for the yield values, the highest values for green herb yield (275.41 kg ha-1), drug herb yield (99.89 kg ha-1), drug-herb percentage (44.00%), green leaf yield (208.97 kg ha-1), green leaf percentage (75.09%) and drog leaf yield (72.48 kg ha-1) were found in the local breed from Bayburt Central location. It was found that the oil percentages, evaluated to determine the quality traits, ranged from 5.39% to 7.02%. The most important fatty acid was alpha-linolenic acid (9.49%-23.1%), followed by linoleic acid (4.18%-13.89%) and palmitic acid (4.05-13.89%). As far as we know, this is the first study investigating tarragon's total oil content and fatty acid composition. The results show that the total oil content of this plant, which has remarkable pharmacological effects, is present in useful quantities compared to the leafy green and does not contain fatty acids that prevent its consumption as food. Therefore, this plant is expected to be used directly in various food products.

Propolis, owing to its antibacterial and anti-inflammatory properties, acts as a cariostatic agent, capable of preventing the accumulation of dental plaque and inhibiting inflammation. The anti-inflammatory properties of propolis are attributed to caffeic acid phenethyl ester (CAPE), which is present in European propolis. The objective of the conducted study was to assess the anti-inflammatory effects of the Polish ethanolic extract of propolis (EEP) and isolated CAPE on stimulated with LPS and IFN-alpha, as well as the combination of LPS and IFN-alpha. The cytotoxicity of the tested compounds was determined using the MTT assay. The concentrations of specific cytokines released by the HGF-1 cell line following treatment with EEP (25-50 mu g/mL) or CAPE (25-50 mu g/mL) were assessed in the culture supernatant. In the tested concentrations, both CAPE and EEP did not exert cytotoxic effects. Our results demonstrate that CAPE reduces TNF-alpha and IL-6 in contrast to EEP. Propolis seems effective in stimulating HGF-1 to release IL-6 and IL-8. A statistically significant difference was observed for IL-8 in HGF-1 stimulated by LPS+IFN-alpha and treated EEP at a concentration of 50 mu g/mL (p = 0.021201). Moreover, we observed that CAPE demonstrates a stronger interaction with IL-8 compared to EEP, especially when CAPE was administered at a concentration of 50 mu g/mL after LPS + IFN-alpha stimulation (p = 0.0005). Analysis of the phenolic profile performed by high-performance liquid chromatography allowed identification and quantification in the EEP sample of six phenolic acids, five flavonoids, and one aromatic ester-CAPE. Propolis and its compound-CAPE-exhibit immunomodulatory properties that influence the inflammatory process. Further studies may contribute to explaining the immunomodulatory action of EEP and CAPE and bring comprehensive conclusions.
