Abu Ubayd’s Understanding Of Naskh;
(Hitit University, 2022) Yaşar, M.A.; Nas, T.
In the period when Islamic sciences were formed, a large number of scholars with absolute ijtihad capacity were trained. One of the scholars mentioned is Abu ‘Ubayd al-Qāsim ibn Sallām al-Khurāsānī al-Harawī who was educated by many famous scholars of the period, had a great influence on both the scientific and political circles. For this reason, he could not be shared by different sect biographers. As a matter of fact, some Shafi’i tabaqat writers counted Ebû Ubeyd as a follower of Imam Shafii. On the other hand, some Hanbali scholars have mentioned Ebû Ubeyd among the class of Hanbali scholars. However, it was concluded that it would be more correct to see Ebû Ubeyd as an independent mujtahid rather than a follower of any madhhab. For, in his own works, the fact that he refers more to Imam Malik rather than Imam Shafii and Ahmad ibn Hanbal and sometimes refers to the views of Abu Hanifa and Imamey indicates this. Ebû Ubeyd, who came to the forefront with his faqih and muhaddis aspects, had a deep knowledge of the subject of naskh, which has a close relationship with these two sciences, and in this regard, he wrote a rare work called en-Nâsiḫ ve’l-mensûḫ fi’l-Ḳurʾâni’lʿazîz ve mâ fîhi mine’l-ferâʾiż ve’s-sünen. While revealing Ebû Ubeyd’s understanding of naskh, his work en-Nâsiḫ ve’l-mensûḫ was used as the main source. In addition to this, his other works related to the subject, especially his work called Kitâbu’l-emvâl, were among the first hand sources that were consulted. It has been tried to determine his approach to naskh based on the statements he made on the subject and the examples he gave in this regard. In this context, Ebû Ubeyd’s approach to the nature and framework of naskh and his views on the evidences that can abrogate each other are examined in this study. Ebû Ubeyd discussed the abrogation in a broader sense as “the modification of a shar’i ruling by a later evidence”, not the established meaning in the methodology as “removal of a shar’i ruling with a later shar’i proof”. In this context, naskh is also used for the allocation of public, the denial of the absolute, the statement of conciseness, the correction of a wrong understanding and the exception made from a general rule. This is known as the understanding of naskh among the companions, tābi‘īn and early convert scholars. However, although Ebû Ubeyd is at the same age as Imam Shafii and has copied and benefited from his works, it is noteworthy that he preferred the predecessor’s approach to the subject rather than the naskh understanding he adopted. It is important to investigate this. He adopted the approach of the public regarding the Shari’a evidences of Ebû Ubeyd that could naskh each other. According to him, the verses of the Qur’an can naskh each other. He gave many examples of this. Another point that draws attention here is to ascribe the concept of naskh used for the verse of the Qur’an by Ebû Ubeyd, from the Lawh-i Mahfuz, in the form of a verse whose recitation is lasting and its meaning is naskhed, and a verse that is removed from people’s hearts by canceling both its recitation and used in different meanings. Ebû Ubeyd stated that sunnah can be naskhed with sunnah, without making any distinction between ahad and mutawatir about sunnah and its naskh. However, despite giving many examples of the naskh of the âhâd sunnah with its own like, no example has been encountered of the naskh of the âhâd sunnah with its own like or with âhâd and the âhâd sunnah with the mutawatir sunnah. As it can be understood from my statements on the subject, Ebû Ubeyd saw that it is permissible to naskh both mutawatir and ahad sunnah with the Qur’an. However, while there is an example for the naskh of the ahad sunnah with the Qur’an in his related works, there is no example for the other. Although there is no clear statement on the issue that the Qur’an can be naskhed with the sunnah, it is understood from some examples that he gives permission for this. © Published by Hitit Ü niversitesi İlahiyat Fakültesi – Hitit University Divinity Faculty, Çorum, Turkey.

Ahmed Anzavur: Soldier, Governor, and Rebel. a Reevaluation of a Late Ottoman Military Man
(Oriental inst Czech Acad Sci, 2023) Yelbasi, Caner
Following the Russian conquest of the North Caucasus, many Muslims from the region were exiled to the Ottoman Empire from the 1860s onwards. They were settled in different parts of the empire from the Balkans to Anatolia to the Syria and Iraq vilayets. By following this policy, the Ottoman state ensured that many Circassians would become part of the Ottoman army, ruling elites, harems and agricultural workforce. Anzavur Ahmed's family was one of them. Although he did not graduate from military school, he participated in the army during the war in Libya (1911), the Balkan Wars (1912-1913), and the First World War (1914-1918). He was also appointed as the governor of Izmit (1920). Anzavur Ahmet is portrayed as a rebel by Turkish official historiography, but in reality, he was much more than that. He was an Ottoman Governor, and supported by Ottoman administrators such as Damad Ferid and Ali Kemal, who were against the Kuvayi Milliye because they believed that the empire would eventually emerge from the chaotic atmosphere of the post-First World War period and make an agreement with the British. This article argues that although Ahmed Anzavur has been labeled a rebel and a traitor according to the official historiography, it is difficult to use these labels given the circumstances of his time.
Amino Acid Profile, Nutrients Content and Yield of Chickpea (Cicer Arietinum L.) Genotypes
(Scibulcom Ltd., 2015) Dogan, Y.; Doğan, Yusuf
Chickpea has significant amounts of all the essential amino acids except sulphur-containing types. It was found that chickpea is a rich source of protein and minerals. The experiments were conducted in a Randomised Complete Block Design with three replications 2013 and 2014 years in South-Eastern Turkey. A total of fifteen varieties, lines and populations were used as materials. In the study were investigated different parameters such as amino acids of protein, seed yield, protein and fat rate in seed, phosphorus, potassium, calcium, manganese, zinc, copper and iron contents and of seeds. The essential amino acid leucine (8.43 mg/100 g in 2013 and 8.59 mg/100 g in 2014) was found in highest concentration, followed by lysine (7.14 mg/100 g in 2013 and 7.27 mg/100 g in 2014) and phenylalanine (5.99 mg/100 g in 2013 and 6.07 mg/100 g in 2014) in the chickpea. Mineral composition of chickpea genotypes showed that they contribute sufficient amount of Ca, P, K, Cu, Zn and Mg in human diets to meet the recommended dietary allowance. According to the average of two years, the highest grain yield was obtained from Diyar-95 variety with 1618 kg ha–1, the lowest grain yield was obtained from M-1 local population with 1104 kg ha–1. © 2015, Scibulcom Ltd.

An Examination of the Effects of Propolis and Quercetin in a Rat Model of Streptozotocin-Induced Diabetic Peripheral Neuropathy
(Mdpi, 2024) Tueredi, Sibel; Celik, Hakim; Dagli, Seyda Nur; Taskin, Seyhan; Seker, Ugur; Deniz, Mustafa
The purpose of this study was to reveal the combined effects of propolis (P) and quercetin (Q) against diabetic peripheral neuropathy developing with streptozotocin-induced diabetes in rats. Sixty-four adult male rats were divided into eight equal groups: control, P (100 mg/kg/day), Q (100 mg/kg/day), P + Q (100 mg/day for both), diabetes mellitus (DM) (single-dose 60 mg/kg streptozotocin), DM + P, DM + Q, and DM + P + Q. The rats were sacrificed, and blood and sciatic nerve tissues were collected. Blood glucose and malondialdehyde (MDA) levels increased, while IL-6 and total antioxidant status decreased in the DM group (p = 0.016 and p = 0.047, respectively). Ultrastructural findings showed degeneration of the axon and myelin sheath. The apoptotic index (AI %), TNF-alpha, and IL-1 beta immunopositivity increased significantly in the DM group (p < 0.001). Morphological structures approaching those of the controls were observed in the DM + P, DM + Q, and DM + P + Q groups. Morphometric measurements increased markedly in all treatment groups (p < 0.001), while blood glucose and MDA levels, AI (%), TNF-alpha, and IL-1 beta immunopositivity decreased. In conclusion, the combined effects of propolis and quercetin in diabetic neuropathy may provide optimal morphological protection with neuroprotective effects by reducing hyperglycemia, and these may represent a key alternative supplement in regenerative medicine.
Antioxidant, Ache Inhibitory, and Anticancer Effects of Verbascum Thapsus Extract
(C M B Assoc, 2023) Zhang, Na; Baran, Ayse; Valioglu, Ferzane; Teng, Lei; Atalar, Mehmet Nuri; Keskin, Cumali; Beilerli, Aferin
Verbascum thapsus (Mullein) is a medicinal plant used in folk medicine to treat various ailments. For this study, the biological functions of Verbascum thapsus (VT) methanol extract were determined in vitro. The plant's methanol extract was created through the maceration process. The phytochemical composition of plant extracts was investigated using liquid chromatography-electrospray ionization tandem mass spectrometry. The antioxidant capacity of the extract was determined using the 2,2-diphenyl-1-picrylhydrazil (DPPH radical) and 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS radical). Cell lines Caco-2 (human colorectal adenocarcinoma cells), LNCaP (Lymph Node Carcinoma of Prostate), and HEK293 (Human embryonic kidney 293 cells) were used to model colon, prostate, and non-cancerous cells. The cytotoxic activity of the plant extract on the proliferation of these cells was determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole) assay protocol. VT extract showed moderate DPPH and ABTS radical scavenging activities at 30 mg/ml concentration. With this, VT extract was determined to inhibit acetylcholinesterase (AChE) enzyme and had strong cytotoxic activity on cancerous cell lines. In addition, our findings clearly showed that the plant extract had greater cytotoxic activity on the viability of cancerous cells compared to non-cancerous (Human embryonic kidney cells; HEK293) cells. The current findings showed that V. thapsus might be a promising anti-cancer medication candidate for the treatment of human colorectal adenocarcinoma and colon cancer, as well as a good source antioxidans.

Armillaria Species Causing Kiwifruit Vine Decline and Root Rot in Northeastern Türkiye: a Growing Concern for Kiwifruit Health
(Wiley, 2024) Turkkan, Muharrem; Bozoglu, Tugba; Dervis, Sibel; Erper, Ismail; Ozer, Goksel
Kiwifruit (Actinidia deliciosa) production in northeastern T & uuml;rkiye is facing an emerging threat from Armillaria root rot. Surveys conducted in August 2021 and 2022 revealed that 10.5%-17.5% of the 200-500 vines within each of 35 kiwifruit orchards in the Per & scedil;embe, G & uuml;lyal & imath; and Alt & imath;nordu districts of Ordu province exhibited symptoms of Armillaria root rot, including complete defoliation. Diseased plants exhibited diagnostic signs on their root collars and woody roots, including white mycelial fans, extensive wood rot and rhizomorphs. A single Armillaria isolate was obtained from each of the 35 symptomatic orchards. Molecular identification, employing DNA sequencing of the large subunit (LSU) region of rDNA, the translation elongation factor subunit 1-alpha (TEF1) gene and the second largest RNA polymerase II B-subunit (RPB2) gene, identified 20 isolates as Armillaria gallica and 15 as A. mellea. Phylogenetic analyses, based on TEF1 alignments, further supported the species identification with a 100% bootstrap value. To examine genetic diversity, start codon targeted (SCoT) marker 13 was used, successfully differentiating the two Armillaria species and revealing three distinct clades. Clades I and II comprised 15 and 5 isolates of A. gallica, respectively, while Clade III contained all 15 A. mellea isolates. Pathogenicity testing on kiwifruit seedlings (cv. Hayward) revealed the ability of both A. gallica and A. mellea isolates to induce disease. Rhizomorph-producing isolates in kiwifruit seedlings displayed high virulence, inducing severe leaf necrosis and seedling mortality, while isolates lacking these structures were non-pathogenic. This study identifies the first global instance of A. gallica causing kiwifruit root rot. This finding, along with the identification of A. mellea as a causal agent in the country, highlights the emerging threat of Armillaria root rot to kiwifruit production in the region.

(Burhan Caglar, 2024) Ciftci, Erdal
This monograph examines the imperial nation-building process in the latter half of the nineteenth century, centering on tent-dwelling Bedouin tribes of inner Syria, predominantly in the Transjordan region. Investigating interactions among Bedouin chiefs, commercial-capitalists, urban elites, and Ottoman officials from the eighteenth to the early twentieth century, it illustrates the central role of Bedouin bureaucrats in fostering mutually beneficial relationships within or outside the state sphere.
Characterization of Durum Wheat (triticum durum L.) Landraces Regarding To Some Agronomic Traits
(Univ Namik Kemal, 2023) Durmaz, Abdurrahman; Aktas, Husnu
This research was conducted in 2019-20 wheat growing season under rainfall condition of Mardin - Artuklu province. 80 durum wheat landraces originated from Southeast Anatolia and 10 registered durum wheat cultivars were evaluated according to Augmented Trail Design. 20 landraces and 10 cultivars were used for each bloc. We determined large variations in durum wheat landraces for observed traits. Results indicated that mean of observed traits of landraces and varieties were ranged between 229 kg/da - 371 kg/da for grain yield; 1313 kg/kg - 1218 kg/kg for biomass, 18.02 % - 14.94 % for grain protein content. Mean thousand kernel weight of landraces and standard varieties changed between 42.9 g and 40.15 g; heading days ranged from 117.8 to 111 days respectively. According to observed data, landraces had longer heading days and grain stage and also higher grain protein content and biomass compare to standard varieties. Results of this study showed that landraces has high potential to increase biomass and grain protein content and they can be used as a genitor in wheat breeding programs to improving desirable durum wheat genotypes. Observation according to GGE biplot methodology (which-wonwhere) indicated that ST8 (Check) and G80 (landrace) have high values for grain yield, number of seed pers spike, seed weight per spike while G8 (landrace) showed high values for thousand grain weight, length of peduncle, plant height, grain protein content, biomass and heading days. Obtained results from this study indicated that landraces should be preserved for sustainable agriculture activities specially for marginal areas, also they have high diversity and useful traits for national and international wheat breeding programs.
Different peripheral substituted phthalocyanines: Synthesis, characterization, aggregation behavior, antioxidant and antibacterial activity
(PLEIADES PUBLISHING INC, 2015) Celebi, M.; Agirtas, M. S.; Dundar, A.
In this study, a novel phthalonitrile, 4-chloro-5-(2-((2-hydroxyethyl)(p-tolyl)amino)ethoxy)phthalonitrile (3), and its metallophthalocyanine derivatives (4-6) are prepared by cyclotetramerization with appropriate metal salts in dimethylformamide. The newly prepared compounds have been characterized by several spectroscopic techniques. All compounds are evaluated for their antioxidant and antibacterial potential. For the antioxidant studies, three tests are applied; DPPH (2,2-diphenyl-1-picrylhydrazylradical) scavenging, metal chelating and reducing power activity. Compound 4 exhibits the best DPPH scavenging activity as 35.2% at 100 mg/L concentration. The metal chelating activities of compounds 3 and 4 are 69.7% and 56.4%, respectively. Reducing power activities of compounds 3 and 4 are higher than alpha-tocopherol which is used as positive control. All compounds show moderate antibacterial activity when compared to the standard antibiotics, amikacin and tetracycline.
distribution of Oxa-Type Carbapenemase Genes in Carbapenem-resistant Acinetobacter Baumannii strains: an Investigation by Real-Time Polymerase Chain Reaction Method
(Doc design informatics Co Ltd, 2019) Demirci, Mehmet; Yigin, Akin; Demir, Cemil
Objective: Carbapenems are the most important broad spectrum antimicrobials used in the treatment of Acinetobacter baumannii infections, but resistance to carbapenems is increasing worldwide. In this study, we aimed to investigate the distribution of OXA-type carbapenemase genes observed in carbapenem-resistant A. baumannii strains by real-time polymerase chain reaction (PCR) method and to provide epidemiological data. Methods: Between January 2016 and January 2018, 20 carbapenem-resistant A. baumannii strains from clinical specimens were included in the study. DNA isolations were performed, and distribution of OXA-type carbapenemase genes were examined using primers and TaqMan probes specific to genes of OXA-23, OXA-24, OXA-51 and OXA-58 carbapenemases by real-time PCR method. Results: Tigecycline was the best choice for carbapenem-resistant A. baumannii strains, of which 16 (80%) were susceptible to this antimicrobial. bla(OXA-51) was detected in all strains, while bla(OXA-24) was detected in only 1 (5%) strain. Of 20 strains, 10 showed the presence of bla(OXA-23) and bla(OXA-51) simultaneously. Conclusions: Simultaneous occurence of bla(OXA-23) and bla(OXA-51 )is remarkable in terms of distribution of OXA-type carbapenemases in carbapenem-resistant A. baumannii strains. Valuable epidemiological data can be obtained by performing routine surveillance of such strains by means of techniques that can produce fast and reliable results such as real-time PCR.

(Springer Publishing Co, 2024) Yesil, Yesim; Oner, Serap; Celik, Gulbiye Dinc; Bay, Habibe; Eksioglu, Aysun; Turfan, Esin Ceber
Objective: This study aims to evaluate the effect of the delivery method on breastfeeding status of primiparous mothers during the first 24 hours. Methods: In this descriptive and analytical study, the sample consisted of 126 primiparous mothers with vaginal (n = 54) and cesarean (n = 72) deliveries. The research data were collected in a hospital through a personal information form and LATCH. Breastfeeding was assessed at the 6th, 12th, and 24th hours within the first 24 -hour period after the delivery. Results: A total of 83.3% of mothers with vaginal delivery started out breastfeeding in the first hour, while the rate was 43.1% for mothers with cesarean delivery. A total of 94.4% of mothers who had vaginal birth gave their babies colostrum, whereas the rate was 80.6% for mothers who had a cesarean birth. While there were no statistically significant differences in Applications 1 and 3 between the LATCH scores of mothers with vaginal and cesarean deliveries, Application 2 produced a significant difference (p < .05). Conclusions: Delivery method influenced the breastfeeding behavior and had an impact particularly on initiation of breastfeeding in the first hour.
Effect of Hmw and Lmw Glutenin Alleles on Quality Traits of Bread Wheat
(Serbian Genetics Soc, 2020) Aktas, Husnu; Sener, Okan
This study was performed to investigate impact of HMW and LMW glutenin alleles on quality traits of bread wheat cultivars. Fifteen bread wheat varieties were used for field trails during 2012-13 and 2013-14 under irrigated conditions of Diyarbakir and Mardin locations, Turkey. We investigated the quality of varieties that have same HMW-GS (High molecular weight subunits) and different LMW-GS (Low molecular weight subunits) or vice versa. Results indicated that GluA3-c > d > e, GluB3-g > b' = i, and GluD3-b = c > a for LMW-GS, and GluB1-7+8 > GluB1-17+18; GluD1-5+10 > GluD1-2+12 for HMW-GS have higher extensograph dough energy, extensibility, resistance, also higher farinograph stability time, gluten index and grain hardness values. The overall evaluation of the results obtained from this study demonstrated that GluA1-1 or 2*, GluB1-7+8 and GluD1-5+10 for HMW glutenin alleles and GluA3-d, GluB3-g and b, GluD3-c for LMW glutenin alleles are associated with a strong gluten structure and accordingly selection of lines harboring these alleles can contribute to the development of genotypes with high quality in wheat breeding programs.
Effects of Concomitant Use of N-acetylcysteine and Cyclosporine A on Acetaminophen-induced Acute Kidney Injury in Mice
(Agricultural Research Communication Centre, 2024) Kocamueftueoglu, Gonca Ozan; Tektemur, Nalan Kaya; Guzel, Elif Erdem; Tektemur, Ahmet; Ozan, Ibrahim Enver
Background: Acetaminophen (APAP), a commonly used analgesic, causes acute kidney injury (AKI) in overdose although it is rare. Mitochondrial dysfunction plays a major role in the pathophysiology of renal damage, although the exact molecular mechanism is unknown. This study aimed to evaluate the potential therapeutic effect of cyclosporin A (CsA), a mitochondrial membrane permeability Methods: Male BALB/c mice were divided into Control, APAP, APAP+NAC, APAP+CsA and APAP+NAC+CsA groups (n=6). A single dose of APAP (400 mg/kg) was administered intraperitoneally. All other treatments (1200 mg/kg NAC, 50 mg/kg CsA) were performed intraperitoneally 3 h after APAP administration. All animals were decapitated and blood samples and kidney tissue samples were collected for evaluation. Serum creatinine (Cr) and blood urea nitrogen (BUN) levels were measured. The kidney tissue 8-hydroxydeoxyguanosine (8-OHdG), cytochrome c (Cytc) and 3-nitrotyrosine (3-NT) levels and cytochrome c (Cytc) expressions were determined. Result: Increased Cr and BUN levels, histopathological examinations and expressions of 8-OHdG, 3-NT and Cytc were detected in the APAP group. Combined NAC+CsA treatment sufficiently reversed oxidative stress, serum Cr and BUN levels and histopathological alterations induced by APAP. Moreover, cytc levels and renal tubular injury were remarkably reduced by combined drug treatment compared to the APAP+NAC group. These data suggest that the therapeutic effect of combined NAC+CsA treatment in mice with APAP-induced nephrotoxicity can be related to the combination of the antioxidant effect of NAC and the mitochondrial MPTP inhibitor effect of CsA.
Effects of Zno Nanoparticules Produced by Green Synthesis on Germination and Seedling Of Salvia Officinalis L. Seeds
(Polish Society Magnesium Research, 2021) Gunes, Zubeyir; Toncer, Ozlem; Eren, Abdullah
Nanotechnology is a research subject in many interdisciplinary engineering fields today. Nanoparticles have important effects on seed germination and seedling growth of plants. The aim of this study has been to produce a 54.68 nm-sized ZnO nanoparticle obtained from the Nigella sativa L. plant by green synthesis. The effect of medicinal sage (Salvia officinalis L.) on germination of plant seeds and seedling growth was investigated. The trial was set up under controlled conditions and conducted for 14 days according to a factorial trial design with 5 replications for each dose (0, 0.5, 1.5 and 2.5 mg ZnO NP kg-1). As a result of ZnO NP application in different doses, germination of Salvia officinalis L. seeds varied between 90-94%, stem length was 1.86-2.92 cm and shoot length was between 1.01-1.98 cm. The highest root and shoot length was obtained after the application of 2.5 mg ZnO kg-1 NP. In the light of the results, ZnO nanoparticles are thought to be useful for seed development and agricultural applications.
An Evaluation of Abrogated Verses From the Perspectives of Acceptance and Rejection
(Cumhuriyet Univ, Fac theology, 2024) Ensari, Abdurrahman
Within the works on Qur'anic sciences, the sections of abrogation in the Qur'an embody an explicit classification among the three categories: 'Abrogated Verses with Persistent Ruling,' 'Persistent Verses with Abrogated Ruling,' and 'Verses Abrogated both in Recitation and Ruling.' The verses that are abrogated both in recitation and ruling are not extant in Qur'an's corpus. The indication of the existence of such verses is based on isolated narrations (ahad hadiths) on this matter. It must be noted that the existence of isolated narrations can't be deemed as a valid indicator of abrogation in recitation of any Qur'anic verse in literal terms. Likewise, verses that are abrogated in recitation are not eligible for being classified as Qur'anic verse in literal terms as they lack the criteria of mass transmission. This situation has led some researchers to strive to prove that there are no verses that are abrogated in recitation. Another group asserts the presence of abrogated recitation verses based on authentic hadiths. In both cases, a problem arises that needs to be addressed. To claim that there are no abrogated recitation verses necessitates rejecting the authentic hadiths on this matter due to the argument that they are isolated (ahad). On the other hand, asserting the existence of abrogated recitation verses also requires referring to a non-mass transmitted (mutawatir) and not present in verbatim of Qur'an. The research has revealed that no study has been conducted to provide a solution to this problem. Hence, this study aims to address and resolve the aforementioned problem. As a conclusion of this study, it is understood that those who deny the existence of abrogated recitation verses are concerned that accepting them could potentially harm the conceptual integrity of the Qur'an. As a result, they make efforts to reject the evidence presented by others. However, it has been observed that none of those who claim the existence of abrogated recitation verses assert that these verses are Qur'anic verses in a conceptual sense. It is understood that what they mean by the recitation of abrogated verses includes the portion of the Book, from its revelation until it is compiled into the Mushaf." It is understood that some verses from this Book have been abrogated in recitation, and the ones mentioned in the hadiths are these verses. The existence of these verses is established by authentic hadiths, and since they are not conceptual Qur'anic verses, the condition of mass transmission (tawatur) is not required for their validity. Hence, it is observed that the verses that are titled "verses abrogated in recitation" are not Qur'anic verses in literal terms that bears authenticity through mass transmission. Instead, their authenticity is proved through authentic sunna, and they are abrogated through sunna as well. It is concluded that two distinct approaches remarkably stem from the difference in authors' discourse depending on the conceptual/terminological application or the lexical meaning of the vocable "verse".
Evaluation of Visceral Adipokines: Omentin, Vaspin, and Visfatin in Patients With Gestational Diabetes Mellitus
(Imr Press, 2024) Yilmaz, Mehmet; Aksin, Serif; Bozbay, Nizamettin; Balsak, Deniz; Aboalhasan, Yasmin; Kurnuc, Fatma Zehra; Batmaz, Ibrahim
Background: Gestational diabetes mellitus (GDM) is a common metabolic disorder characterized by glucose intolerance that develops during pregnancy. The underlying pathophysiological mechanisms of GDM involve complex interactions between genetic, environmental, and hormonal factors, including adipokines secreted by visceral adipose tissue. Omentin, vaspin, and visfatin are adipokines believed to influence insulin sensitivity and inflammation, though their precise relationship with GDM remains unclear. This study aimed to examine the association between these adipokines and GDM. Methods: This single-center, prospective controlled cohort study included 87 pregnant patients diagnosed with GDM via an oral glucose tolerance test (OGTT) between the 24th and 28th weeks of gestation, along with 87 control subjects without GDM. Serum levels of omentin, vaspin, and visfatin were measured using enzyme-linked immunosorbent assay (ELISA), and their association with GDM was analyzed. Results: Our results demonstrated that omentin levels were significantly higher in the GDM group compared to the control group (p = 0.012), while no significant differences were observed in vaspin and visfatin levels (p > 0.05). An omentin cut-off value of 29.0 ng/mL predicted GDM with 59.1% sensitivity and 59.1% specificity, suggesting its potential as a biomarker for GDM. Conclusions: This study underscores the unique role of omentin in GDM, in contrast to the non-significant changes observed in vaspin and visfatin levels. The elevated omentin levels in GDM patients suggest its potential as a biomarker for diagnosing and managing GDM. Further research is needed to elucidate the mechanisms through which omentin contributes to the pathophysiology of GDM.
An Evaluation on Metaphorical Definitions of Mu'tazila Methodologists
(Cumhuriyet Univ, Fac theology, 2024) Akan, Yasin
Some concepts discussed in the field of religion have been the subjects of more than one discipline; and these concepts have been studied from different perspectives in each discipline. Literal meaning and metaphor, which have an important place in understanding the religious rules (religious nas), are such concepts. Although literal meaning and metaphor seem to be solely linguistic concepts, they have substantially become the subjects of many religious disciplines. Jurisprudence methodology is one of the basic religious disciplines that intensively use these concepts. Although there was no definition of metaphor in the early language sources, it has been generally accepted as "the use of words other than the meaning given in the language". Imam Shafii (d. 204/820), the author of the first work of Islamic jurisprudence methodology that has survived to the present day, and Jahiz (d. 255/869), Abu Ali al-Jubbai (d. 303/916) and Abu Hashim al-Jubbai (d.. 321/933) also used metaphor without defining the concept while basing their views. Two definitions about metaphor were narrated from Abu Abdullah al-Basri (d. 369/979-80), one of the kalam methodologists, and who first made a definition of metaphor. Although the definitions made by Abu Abdullah had a significant impact on the definitions of later jurisprudence methodologists, his close methodology scholar followers did not accept these definitions. While Jessas (d. 370/981) and Baqillani (d. 403/1013), made a simple definition that does not include intellectual considerations, Abu l-Husayn al-Basri(d. 436/1044), one of the Mu'tazila methodologists, developed a complex definition that includes theological considerations regarding metaphor. In his definition, Abu l-Husayn first pointed out that the type of address is one of the basic determining factors in order to reveal that the word is used in a metaphorical sense. In his definition, Abu l-Husayn, secondly, pointed out that the metaphoric meaning of the word, as well as its literal meaning, is made within the linguistic rules. In addition, although Abu l-Husayn did not express it clearly in his definition, in his evaluations within the framework of the subject, he emphasized that the presumption is one of the main determining factors in order to reveal that the word is used in a metaphorical sense. According to him, only if there is a presumption that prevents the use of the word in its literal sense, is the word taken to have a figurative meaning. In this study, which is about the metaphor definitions of Mu'tazila methodologists, first of all, the metaphor definitions put forward by linguists and jurisprudence methodology scholars other than Mu'tazila in the first five centuries were examined. Then, the metaphoric definitions of Mu'tazila methodologists were evaluated. Among the metaphorical definitions of Mu'tazila scholars, the definition of Abu'l-Husayn al-Basri, which takes into account the intellectual considerations of the school, was closely examined. Since the definition of Qadi Abd al-Jabbar, one of the Mu'tazila thinkers, reflecting his understanding of metaphor has not survived to the present day, his views were also examined while examining Ebu'l-Husayn's definition. Thus, it was revealed that Ebu'l-Husayn's definition of metaphor, which contains intense theological considerations in the field of jurisprudence, is basically based on Qadi Abd al-Jabbar. Finally, in our study, the effect of the definition of metaphor conveyed by Abu'l-Husayn on the methodologists of other schools was also revealed. It was stated that this definition was accepted by Fakhr al-din al-Razi (d. 606/1210), one of the methodologists in question, and Razi's views within the framework of this definition were discussed on the intellectual basis of Mu'tazila.
Experimental and theoretical investigation of adsorption and inhibition properties of 2-Amino-1,3,5-triazine-4,6-dithiol against corrosion in hydrochloric acid solution on mild steel
(Elsevier, 2023) Arslanhan, Selim; Yıldız, Reşit; Döner, Ali; Yıldız, Reşit
In this work, 2-Amino-1,3,5-triazine-4,6-dithiol (2-ATD) as novel and high efficiency corrosion inhibitor has been investigated for mild steel (MS) corrosion in 0.5 M HCl solution using electrochemical methods, scanning electron microscopy (SEM), energy disperse X-ray spectroscopy (EDX), atomic force microscopy (AFM) and quantum chemical calculation methods. Potentiodynamic polarization (PDP) curves indicate that 2-ATD is mixed type inhibitor, corrosion inhibition efficiency increased with increasing inhibitor concentration and reached its value of 96.5%. Evolution of exposure time versus corrosion behavior of 2-ATD is examined in corrosive medium. While corrosion potential (Ecorr) shifted more negative values, polarization resistances (Rp) decreased after 120 h exposure time due to the corrosion process. H2 volume is measured in uninhibited and inhibited solutions (10 mM 2-ATD) after 120 h exposure time. Very low volume (3.6 mL cm-2) of H2 is obtained on MS electrode in inhibited solution after 120 h of exposure, indicating that 2-ATD covers the entire surface against aggressive attack and retards the both anodic dissolution of MS and cathodic hydrogen evolution reactions. The adsorption process proposal is the Langmuir isotherm which is most suitable. Adsorption and thermodynamic parameters show that 2-ATD has a strong adsorption effect onto MS surface and includes mixed adsorption style (physical and chemical). Corrosion current density increases with increasing temperature and high activation energy (Ea) proves the strong adsorption of 2-ATD on the MS surface. Anti-corrosion mechanism of 2-ATD is described more detail with the potential of zero charge method. SEM, EDX and AFM analysis support the obtained results of electrochemical methods and confirm the existence of protective layer and strong adsorption of 2-ATD on the MS surface. Chronoamperometry test shows that current densities are almost constant whole experiment in the presence of organic film. Finally, quantum chemical calculation method of 2-ATD in blank solution is performed to investigate the active sites for possible attachment with MS surface.
Exposure To High-Molecular Polyvinyl Chloride Alters Bacterial Diversity in the Gut Microbiota of the Wistar Rat
(Middle Pomeranian Sci Soc Env Prot, 2024) Pekmezekmek, Ayper Boga; Emre, Mustafa; Kalay, Betuel; Tunc, Erdal; Kocahan, Sayad; Emre, Nesrin; Emre, Toygar
The physical and chemical characteristics of microplastics make it easier for contaminants to adhere to the surface of the particles, acting as a vehicle for toxins to reach organisms after ingestion. The "most microbiome" comprises all the microorganisms present in our bodies as a whole because it has a big surface area and provides nutrient-rich components for the digestive system's germs. In this investigation, metagenome analysis was used to determine the impact of long-term administration of High-Molecular Weight-Polyvinyl Chloride microplastics to young Wistar rats on the gut microbiota. Forty adult rats in total were employed, with 15 first-group and 15 second-group experimental groups and 10 controls. Pellets made specifically for feeding rats are produced. Following the procedure, the rats were anaesthetised with ketamine and xylasine before being dissected. Due to the small number of samples, alpha diversity in the gut metagenome study did not demonstrate statistically significant variations, but it did illustrate differences in bacterial diversity and density. In particular, it has been discovered that bacterial diversity is higher in experimental groups. According to the control groups, in the assay groups, the intestinal microbiome, dominated by Escherichia coli, Shigella, and Lactobacillus, was assessed as an increase in metabolic pathways related to microplastic exposure and pathogenicity in general. The findings demonstrate the necessity for extreme caution in the manufacture and use of plastics that pose a risk to the welfare of living things.
The Flesh Cannot See the Word: 'Nestorianising' Chalcedonians in the Seventh to Ninth Centuries AD
(BRILL ACADEMIC PUBLISHERS, 2013) Krausmueller, Dirk
Towards the end of the eighth century the Nestorian Patriarch Timothy convened a council, which condemned several mystics for having held the belief that Christ's humanity could see his divinity. This article draws attention to a Chalcedonian sermon on the Annunciation whose author shared Patriarch Timothy's views. Through comparison with the Questions and Answers of Pseudo-Athanasius and with Theodore of Stoudios' sermon on the Angels it shows that the author of the sermon on the Annunciation participated in a wider Chalcedonian debate about the ability of human beings to see God and the equally invisible angels and souls. Having presented the evidence it makes the case that as regards this topic the Eastern Christian religious discourse had not yet fragmented along sectarian and political boundaries and that throughout the East Christians were experiencing the same anxieties and responding to them in remarkably similar ways.
