Abluted capitalism: Ali Shariati's critique of capitalism in his reading of Islamic Economy
(Sage, 2015) Şengül, Serdar
Islamic sociologist Ali Shariati is a leading figure of the reconstruction of religious thought in the Islamic world known especially for his anti-capitalist stance and leftist reading of Islamic history. In the philosophy of history that he developed, he classified religions as religions of tawheed (unicity of God) and religions of shirk (multiple gods). According to this new reading of history, the main struggle is not between religion and secularism but between religions of tawheed and of sheerk. The issue of the gaining and the distribution of the property is central to his classification. Shariati argued that followers of tawheed and of sheerk can be found in all religions including Islam. To support his argument Shariati explored how capitalistic understanding of Islam has been developed and legalised while anti-capitalist messages and orders of Islam were marginalised and illegalised just after the death of the Prophet Mohammed. He analysed the rivalry between his close companions over the content of a proper Islamic economic order and how this rivalry gave way to two contradicting understanding of Islam, marks of which can be seen today in the contemporary Muslim world. He coined the term abluted capitalism' to define the economic policies of Muslim sovereigns to make Islam compatible with capitalist economic principles.

(Springer Science and Business Media Deutschland GmbH, 2023) Yiğit, Uğur; Türkkan, Muharrem; İlhan, Hasan; Şimşek, Tuncay; Güler, Ömer; Derviş, Sibel
This study aimed to evaluate the antifungal activity of copper-boron (Cu-B) nanoalloys against a range of Phytophthora species, including P. capsici, P. citrophthora, P. palmivora, P. cinnamomi, P. nicotianae, P. cactorum, P. plurivora, P. inundata, and P. megasperma. The nanoalloys were synthesized via mechanical alloying under an argon atmosphere, resulting in the formation of nanocrystalline Cu-B nanoalloys with irregular morphology and particle sizes ranging from 50 to 240 nm. At a concentration of 250 µg mL−1, the Cu-B nanoalloys demonstrated complete inhibition of mycelial growth, sporangium production, and zoospore germination in all tested Phytophthora species. The EC50 values for mycelial growth ranged from 28.02 to 120.17 µg mL−1, while for sporangium production and zoospore germination, they were below 10 µg mL−1. Furthermore, the nanoalloys exhibited fungicidal activity against specific Phytophthora species, such as P. capsici, P. citrophthora, P. inundata, and P. megasperma, at concentrations of 100, 250, 250, and 250 µg mL−1, respectively. Notably, the Cu-B nanoalloys displayed significant protective and curative effects on tuber rot severity in P. nicotianae-inoculated potatoes, resulting in reductions of 94.13% and 92.61% compared to the control, respectively, at a concentration of 10 µg mL−1 (P < 0.05). These findings highlight the potential of Cu-B nanoalloys as a promising fungicide for the management of plant diseases caused by Phytophthora spp.
Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation
(SPRINGER HEIDELBERG, 2019) Yildiz, Resit; Yıldız, Reşit
2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.
Adsorption Performance of bacillus Licheniformis Sp. Bacteria Isolated From the Soil of the Tigris River on Mercury in Aqueous Solutions
(Taylor & Francis Ltd, 2022) Baran, M. Firat; Yildirim, Ayfer; Acay, Hilal; Keskin, Cumali; Aygun, Husamettin
Mercury is known to be one of the most toxic heavy metals in the environment and is released into the water systems in significant quantities through natural events and industrial process activities. Many chemical materials are used as adsorbents in the removal of toxic metals from the environment and wastewaters. However, using microorganisms as bio-sorbents instead of chemical materials has become common recently due to their low cost, easy availability and presence in nature. In this study, Bacillus licheniformis in the soil isolated from the Tigris River was used as bio-sorbent. The mercury (Hg(II)) absorption behaviour of Bacillus licheniformis bacteria (BLB) was investigated using inductively coupled plasma mass spectrometry. The effects of equilibrium of adsorption time, temperature, adsorbent dosage and pH on the adsorption of Hg (II) onto BLB were determined. The maximum adsorption capacity of Hg (II) onto BLB was determined as 82.12 mg/g (T = 25 degrees C, pH 5, Co = 50 mg/L, m = 25 mg). The BLB was characterised using Fourier transform infrared spectroscopy analysis, thermal gravimetric analysis/differential thermal analysis, scanning electron microscopy analysis and energy-dispersive X-ray spectroscopy analysis. In addition, pseudo-first-order and pseudo-second-order kinetic models were applied. The equilibrium data for the adsorption of Hg(II) onto BLB were examined by the Langmuir and Freundlich isotherm models. The activation energy was calculated using the pseudo-second-order rate constant. These results suggested the BLB can be used as an efficient adsorbent for the removal of Hg(II) metal ions from wastewater. When the results of bio-sorption studies were examined, it was found that the bio-sorbent could be reused easily. The present study suggests that microorganism bio-sorbents are useful for the efficient removal of mercury from aqueous solutions.
Aflatoxin M1 in Human Breast Milk in Southeastern Turkey
(Springer Verlag, 2017) Kılıç Altun, S.; Gürbüz, S.; Ayağ, E.
This study was performed to determine aflatoxin M1 (AFM1) in human breast milk samples collected in Şanlıurfa, located in Southeastern region of Turkey, and to investigate a possible correlation between AFM1 occurrence (frequency and levels) and sampling seasons. Human breast milk samples collected in December 2014 and in June 2015 from a total of 74 nursing women, both outpatient and inpatient volunteers in hospitals located in Şanlıurfa, Turkey, were analyzed using competitive enzyme-linked immunosorbent assay (ELISA) for the presence of AFM1. AFM1 was detected in 66 (89.2%) out of 74 samples at an average concentration of 19.0 ± 13.0 ng/l (min.-max., 9.6–80 ng/l). There was a statistically significant difference between December and June concerning AFM1 levels (p < 0.05). Further detailed studies will be needed to determine the main sources of aflatoxins in food, to establish protection strategies against maternal and infant exposure to these mycotoxins. © 2016, Society for Mycotoxin Research and Springer-Verlag Berlin Heidelberg.
Allelic variations of glutenin subunits and their association with quality traits in bread wheat genotypes
(2017) Aktaş, Hüsnü; Baloch, Faheem Shehzad
The present study was conducted to evaluate the genotype × environment interaction of the yield and quality traits for five bread wheat varieties commonly grown in the Southeastern Anatolia Region of Turkey and 20 advanced lines developed within the framework of the International Winter Wheat Improvement Project. We also determined the allelic pattern of the Glu-1 and Glu-3 loci of these genotypes and examined whether these loci had an effect on the quality traits. There was a significant variation among the genotypes and environments in terms of grain yield, protein content, sedimentation volume (SV), and the extensograph dough energy value (EDEV). The results of the study indicated that genotypic effect was more influential on SV and EDEV than environmental effect; thus, both traits could be used in breeding programs to develop elite cultivars with better quality. Twelve different high-molecularweight (HMW) glutenin alleles were identified at the Glu-A1, Glu-B1, and Glu-D1 loci, resulting in 14 allelic combinations, and 17 different alleles were observed in 19 combinations for low-molecular-weight (LMW) subunits. Furthermore, among all the genotypes, 13 + 16 and 13 + 19 alleles at Glu-B1 and 5 + 12 at Glu-D1 were observed to have the lowest frequency. Our study indicated that the combinations of HMW glutenin alleles with 2* at Glu-A1, 17 + 18 and 13 + 16 at Glu-B1, and 5 + 10 at Glu-D1, as well as the combinations of LMW alleles with subunits c and d at Glu-A3; subunits d, b, c, and g at Glu-B3; and subunits a and b at Glu-D3 had positive effects on the quality traits.
Analyses of Po-Based Fuzzy Logic-Controlled Mppt and Incremental Conductance Mppt Algorithms in Pv Systems
(Mdpi, 2025) Cakmak, Fevzi; Aydogmus, Zafer; Tur, Mehmet Rida
This manuscript aims to increase the utilization of solar energy, which is both environmentally friendly and easily accessible, to satisfy the energy needs of developing countries. In order to achieve this goal, maximum power generation should be provided from photovoltaic panels. Several maximum power point tracking (MPPT) methods are utilized for maximum power generation in photovoltaic panel systems under different weather conditions. In this paper, a novel intelligent hybrid fuzzy logic-controlled maximum power point tracking algorithm founded on the perturb and observe (PO) algorithm is presented. The proposed fuzzy logic controller algorithm and the incremental conductivity maximum power point tracking algorithm were simulated in a MATLAB(2018b version)/Simulink environment and evaluated by comparing the results. Four Sharp ND-F4Q295 solar panels, two in series and two in parallel, were used for the simulation. In this study, the voltage ripple of the proposed hybrid method was measured at 1% compared to the classical incremental conductivity method, while it was 8.6% in the IncCon method. Similarly, the current ripple was 1.08% in the proposed hybrid FLC method, while the current ripple was 9.27% in the IncCon method. It is observed that the proposed smart method stabilizes the system voltage faster, at 25 ms, in the event of sudden weather changes.

(Taylor & Francis Ltd, 2022) Kizmaz, Veysi
This study was carried out to determine the distribution of total, phospholipid and triacylglycerol fatty acid composition in salted and fresh fish of pearl mullet. Fatty acid analyses were performed in muscle tissues of the fish samples. Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA), Omega-3 (n-3), Omega-6 (n-6) which are important for health, were determined in the analyses. The distribution of total and TAG fatty acids in males and females was similar. It was determined that the changes were in the Phospholipid. N-3/n-6 ratio showed a similar distribution in both female and male individuals. In particular, the results obtained may benefit the fisheries industry, nutritionists and researchers, as the nutritional value of the fish is high.
Anoxybacillus sp. SO B1-Immobilized Amberlite XAD-16 for Solid-Phase Preconcentration of Cu(II) and Pb(II) and Their Determinations by Flame Atomic Absorption Spectrometry
(TAYLOR & FRANCIS INC, 2015) Oral, Elif Varhan; Ozdemir, Sadin; Dolak, Ibrahim; Okumus, Veysi; Dundar, Abdurrahman; Ziyadanogullari, Berrin; Aksoy, Zehra; Onat, Ruken
A new method for the determination of Cu(II) and Pb(II) by flame atomic absorption spectrometry (FAAS) after preconcentrating on a column containing Anoxybacillus sp. SO B1-immobilized Amberlite XAD-16 was developed. The functional groups of Anoxybacillus sp. SO B1 immobilized on Amberlite XAD-16 were characterized in KBr tablets by Fourier transform infrared (FT-IR) spectrometry. Various parameters such as pH, amount of the adsorbent, eluent type and volume, and flow rate of the sample solution were studied. The optimum pH values of quantitative sorption for Cu(II) and Pb(II) were found to be pH 7.0 and 5.0 and Cu(II) and Pb(II) ions could be quantitatively eluted with 5.0ml of 1.0mol L-1 HCI and 10.0ml of 0.25mol L-1 HNO3, respectively. Recoveries of Cu(II) and Pb(II) were found to be 100.9 +/- 1.57% and 100.3 +/- 0.49% (N = 5), the limits of detection of Cu(II) and Pb(II) in the determination by FAAS (3s, N = 10) were found to be 0.8 and 1.6 mu g L-1, respectively. The proposed enrichment method was applied for metal ion determination from water samples such as two parts of Tigris River water in Diyarbakir and Elazig, Lake of Hazar in Elazig, and tap water in Diyarbakir. Furthermore, the accuracy of the proposed method was verified by studying the analytical recovery and by analyzing certified reference material (NCS-DC 73350 leaves of poplar).

(TAYLOR & FRANCIS INC, 2013) Dundar, Abdurrahman; Okumus, Veysi; Ozdemir, Sadin; Yildiz, Abdunnasir
The ethanolic extracts of dried cultured mycelia of Pleurotus ostreatus, Pleurotus eryngii, Pleurotus florida, and Pleurotus sajor-caju were analyzed for antioxidant activity in different systems. Tests used are as follows: reducing power, free radical scavenging, superoxide anion radical scavenging, total antioxidant activity, metal chelating activitiy, etc.; total phenolic content was determined. The percentage inhibition of P. ostreatus, P. eryngii, P. florida, and P. sajor-caju at 20 mg/mL concentration on peroxidation in a -carotenelinoleic acid system was 57.19, 60.68, 62.12, and 58.81%, respectively. The reducing power of P. eryngii was higher than the other samples, and its value was 0.86 at 10 mg/mL concentration. P. ostreatus and P. sajor-caju proved to be better at scavenging superoxide anion radicals than the P. eryngii and P. florida. In the scavenging effect of DPPH radical test, P. ostreatus showed the highest activity potential and P. sajor-caju showed the strongest metal chelating capacity.

(Bmc, 2025) Soner, Serdar; Aktan, Adem; Kilic, Raif; Guzel, Hamdullah; Tastan, Ercan; Oksul, Metin; Guzel, Tuncay
Objective The triglyceride glucose (TyG) index is a biomarker of insulin resistance and is associated with an increased risk of cardiovascular events. Contrast-induced nephropathy (CIN) is an important complication that causes poor outcomes in patients undergoing percutaneous coronary intervention (PCI). In this study, we aimed to investigate the relationship between the TyG index and CIN and mortality in patients who underwent PCI due to chronic total coronary occlusion (CTO). Methods Two hundred eighteen individuals from three separate medical centers who underwent procedural PCI between February 2010 and April 2012 and had a CTO lesion in at least one coronary artery were recruited. According to the TyG index, patients were divided into two groups. Patients with a TyG index >= 8.65 were included in Group 1, and patients with a TyG index < 8.65 were included in Group 2. Patients were followed up for 96 months. The main outcome was the development of CIN and mortality. Results The mean age of the patients (65.8 +/- 10.94 vs. 61.68 +/- 11.4, P = 0.009), diabetes mellitus (60 [44.8%] vs. 11 [13.1%], P < 0.001), and dyslipidemia rates (52 [38.8%] vs. 21 [25%], P = 0.036) were higher in group 1. In multivariable logistic regression analysis, it was seen that age (OR = 1.04, 95% CI = 1.01-1.08, P = 0.020), chronic kidney disease (OR = 2.34, 95% CI = 1.02-5.33, P = 0.044), peripheral artery disease (OR = 5.66, 95% CI = 1.24-25.91, p = 0.026), LVEF (OR = 0.95, 95% CI = 0.92-0.99, P = 0.005), LDL cholesterol levels (OR = 1.00, 95%CI = 1.00-1.02, P = 0.024) and TyG index (OR = 2.17, 95% CI = 1.21-3.89, P = 0.009) were independent predictors of the development of CIN. Conclusion Our study demonstrates a correlation between the TyG index and the prevalence of CIN in patients with CTO undergoing PCI. Adding the TyG index to the routine clinical evaluation of patients with CTO undergoing PCI may help protect patients from the development of CIN.
Association with Leptin Gene c.-2548 G > A Polymorphism, Serum Leptin Levels, and Body Mass Index in Turkish Obese Patients
(HUMANA PRESS INC, 2013) Say Şahin, Deniz; Tümer, Cemil; Demir, Cemil; Çelik, M. Murat; Çelik, Mustafa; Uçar, Edip; Güneşaçar, Ramazan
Leptin is a protein hormone which plays a critical role in the regulation of both body-weight through reducing food intake and stimulating energy expenditure. Several polymorphisms in leptin gene (LEP), which encodes for leptin, have been described. However, its association with obesity is still controversial. Therefore, in the present study, we aimed to investigate whether LEP c.-2548 G > A polymorphism was associated with serum leptin levels, lipid parameters, and body mass index in Turkish obese patients. Forty-seven obese patients and 48 healthy individuals were included in the study. Blood samples were collected for DNA extraction. LEP c.-2548 G > A polymorphism were detected using polymerase chain reaction-restriction fragment length polymorphism technique. Serum leptin levels and lipid parameters were measured by ELISA and enzyme colorimetric assay techniques, respectively. GA or AA genotypes and A allele carrier frequencies of the c.-2548 G > A polymorphism in the LEP were higher in obese (38.3, 34.0 and 72.3 %) when compared with controls (14.6, 12.5, and 27.1 %; p = 0.011, 0.016, and 0.002, respectively). On the other hand, AA or AG genotypes were also related to increased serum leptin levels (p < 0.001) and body mass index (p < 0.0001). All these consequences showed that LEP -2548 AA or AG genotypes are important predictors for increased levels of leptin and BMI in Turkish obese patients and it may be a useful marker for obesity risk in our population.

(Tubitak Scientific & Technological Research Council Turkey, 2024) Dahnoun, Kheira; Djadouni, Fatima; Essghaier, Badiaa; Naccache, Chahnez; Zitouna, Nadia; Zehdi-Azouzi, Salwa; Bourguiba, Hedia
Heavy metal pollution is a major environmental issue that has a negative impact on soil quality and food security. As result, heavy metal removal or remediation from hazardous sites has become mandatory. Bioremediation based on microorganisms is promising method to remediate heavy metal-contaminated areas due to its ecofriendly, cost-effective, and highly efficient characteristics. This study aimed to isolate, identify, and characterize rhizospheric bacteria able to resist, reduce, and detoxify heavy metals [chromium (Cr), nickel (Ni), and aluminum (Al)] from agricultural soil. Two isolates were chosen due to their high level of heavy metal resistance and could serve as potential in situ remediation agents at the site of isolation. On the basis of morphological, cultural, biochemical, and molecular characterization, these two isolates were identified as Pseudomonas aeruginosa (S1) and Bacillus cereus (S2). The results revealed a minimum inhibitory concentrations (MICs) of the three heavy metals studied, ranging from 1000 to 1400 mu g/mL for the two bacterial isolates. Atomic absorption spectroscopy analysis was used to evaluate the degrading potential. B. cereus was able to reduce Cr and Al more than P. aeruginosa (42% and 67.78% vs. 38.44% and 58.85, respectively). On the other hand, P. aeruginosa showed a higher capacity to degrade Ni than B. cereus (62.33% and 50.76%, respectively). The findings of the analysis revealed information regarding the use of these heavy metal-resistant bacterial isolates as potential bioremediation agents in contaminated environments. Microbial bioremediation offers sustainable alternatives to the traditional physical or chemical remediation technologies of agricultural land.
Comparative Analysis of Carbon Footprints From Away and Home Matches: a Study on Leading Basketball and Football Teams in Türkiye
(Mdpi, 2024) Cetin, Arif; Pekel, Aydin; Ozman, Cemal; Ozgur, Beyhan; Demir, Ayse
Problem: Basketball and football teams in T & uuml;rkiye have the capacity to travel hundreds of kilometres for league matches. In general, such major leagues and leading teams travelling from T & uuml;rkiye have not been sufficiently researched in the context of T & uuml;rkiye's leading leagues and teams. In this context, the aim of this study is to assess and compare the carbon footprint of the transport activities of basketball and football teams in T & uuml;rkiye for their home and away matches for the 2023-2024 season. Methods: The research is based on EN 16258 and ICAO carbon emissions methodologies. This study aims to calculate and compare the carbon footprint of different transport methods, including bus and plane, used by five basketball and football teams in T & uuml;rkiye. Results: The findings show that there are significant differences between the teams in terms of travelling distances and carbon footprints. Trabzonspor from the Black Sea region released the highest CO2 emissions from air travel with a total of 91,667.1 kgCO2e, while Fenerbah & ccedil;e Beko had the lowest CO2 emissions with 5316.72 kgCO2e. In terms of bus travel, Gaziantep FK led the CO2 emissions with 4356.45 kgCO2e, while T & uuml;rk Telekom was the team with the lowest CO2 emissions with 1233.225 kgCO2e. The findings also reveal a notable difference in the number of trees teams need to plant to offset their carbon emissions. Because of their travel patterns, Antalyaspor would need to plant 3481 trees, whereas Fenerbah & ccedil;e Beko would only need to plant 348 trees. Conclusions: Air travel is emerging as the dominant source of CO2 emissions and has a greater impact on the environmental impact of teams that rely heavily on airplanes. In this study, the league structure and duration play a critical role in shaping the carbon footprint of sports teams. The football season, which is longer compared to basketball, requires more frequent travel, especially for teams in more remote regions, resulting in higher carbon emissions than basketball. The dominance of Marmara region teams in basketball has a negative impact on the carbon footprint since these teams generally have shorter travel distances.

(SPRINGER, 2018) Ozdemir, Sadin; Oduncu, M. Kadir; Kilinc, Ersin; Soylak, Mustafa
Bacillus vallismortis and Bacillus mojavensis were loaded onto Amberlite XAD-4 resin and used for solid phase extraction (SPE) of uranium(VI). A quick and simple UV-Vis spectrophotometric method was used to determine U(VI) ion. The best experimental conditions were determined as being a pH of 5.0; a sample flow rate of 2.0 mL min(-1); 200.0 mg of biosorbent; 800 mg of Amberlite XAD-4, and 5.0 mL of 1 mol L-1 HCl as desorption solution for both immobilized bacteria. The preconcentration factors were achieved as 80 for both solid phase extractor. The developed methods were validated by applying to reference water and tea samples.
Comparing the Efficacy of Regorafenib and 5-Fluorouracil Rechallenge Chemotherapy in the Third-Line Treatment of Metastatic Colorectal Cancer
(Bmc, 2024) Tasci, Elif Seno; Oyan, Basak; Sonmez, Ozlem; Mutlu, Arda Ulas; Atci, Muhammed Mustafa; Sakin, Abdullah; Bozkurt, Mustafa
Background The optimal treatment for metastatic colorectal cancer (mCRC) after the second line is still controversial. Regorafenib has been the standard of care in this setting as it improved overall survival (OS) compared to placebo. In real-world practice chemotherapy rechallenge is also a preferred option even though supporting evidence is not enough. We aim to compare the efficacy of regorafenib and 5-fluorouracil-based (5-FU) rechallenge treatment in the third line setting of mCRC.Methods In this retrospective multi-institutional trial, mCRC patients from 21 oncology centers who progressed after 2 lines of chemotherapy were analyzed. Patients who were treated with regorafenib or rechallenge therapy in the third-line setting were eligible. Rechallenge chemotherapy was identified as the re-use of the 5-FU based regimen which was administered in one of the previous treatment lines. OS, disease control rate (DCR), progression free survival (PFS) and toxicity were analyzed.Results Three hundred ninety-four mCRC patients were included in the study. 128 (32.5%) were in the rechallenge, and 266 (67.5%) were in the regorafenib group. Median PFS was 5.82 months in rechallenge and 4 months in regorafenib arms (hazard ratio:1.45,95% CI, p = 0.167). DCR was higher in the rechallenge group than regorafenib (77% vs 49.5%, respectively, p = < 0.001). Median OS after the third-line treatment was 11.99 (95% CI, 9.49-14.49) and 8.08 months (95% CI, 6.88-9.29) for rechallenge and regorafenib groups, respectively (hazard ratio:1.51, 95% CI, p < 0.001). More adverse effects and discontinuation were seen with regorafenib treatment.Conclusion Our study revealed that higher disease control and OS rates were achieved with rechallenge treatment compared to regorafenib, especially in patients who achieved disease control in one of the first two lines of therapy.
Comparison of Breastfeeding Behaviors of Mothers Toward Infants by Ethnic Groups: an Example of a Multicultural City
(Mary Ann Liebert, inc, 2025) Butun, Ahmet; Deger, Vasfiye Bayram
Introduction: Breastfeeding practices vary widely among different ethnic groups and are influenced by cultural, social, economic, and educational factors. The aim of this study was to compare the breastfeeding behaviors of mothers toward infants in different ethnic groups.Methods: This descriptive cross-sectional study included women of four ethnic groups (Assyrian, Turkish, Arab, and Kurdish) living in Mardin, Turkey. The study was completed with 180 Assyrian, 184 Turkish, 175 Arab, and 169 Kurdish women. In total, 708 women participated in this study. Data were collected between August 12, 2024, and September 22, 2024.Results: The highest rate of traditional breastfeeding practices was seen in Kurdish (99.4%), whereas this rate was 97.3% in Turkish, 96% in Arab, and 84.4% in Assyrian. The highest rate of giving breast milk immediately after birth was in Assyrian (71.7%), while this rate was 69.3% in Turkish, 61.9% in Kurdish, and 47% in Arab (p = 0.000). The rate of those who waited for three calls to prayer to feed the baby was 13.1% in Kurdish, 11.3% in Arab, 9.5% in Turkish, and 7.9% in Assyrian. The rate of those who did not give the first milk (colostrum) to the baby was 15.8% in Assyrian, 11.7% in Turkish, 6.5% in Kurdish, and 6% in Arab. The rate of those who give sugared water as the baby's first nutrient was 37.5% in Arab, 20.8% in Kurdish, 11.7% in Turkish, and 9.2% in Assyrian. Increased education levels were associated with decreased rates of the presence of traditional practices.Conclusion: This study provides novel results regarding the comparison of breastfeeding behaviors among ethnic groups living in the same city. Comparing breastfeeding practices across the four ethnic groups allowed us to better understand different breastfeeding practices, which could lead to the development of culturally sensitive interventions to improve the health of children and mothers. Educating the community about the benefits of breastfeeding and the risks associated with some traditional practices could contribute to public health.
Comparison of New Secondgeneration H1 Receptor Blockers With Some Molecules; a Study Involving Dft, Molecular Docking, Admet, Biological Target and Activity
(Bmc, 2025) Unsal, Velid; Oner, Erkan; Yildiz, Resit; Mert, Basak Dogru; Yıldız, Reşit
Although the antiallergic properties of compounds such as CAPE, Melatonin, Curcumin, and Vitamin C have been poorly discussed by experimental studies, the antiallergic properties of these famous molecules have never been discussed with calculations. The histamine-1 receptor (H1R) belongs to the family of rhodopsin-like G-protein-coupled receptors expressed in cells that mediate allergies and other pathophysiological diseases. In this study, pharmacological activities of FDA-approved second generation H1 antihistamines (Levocetirizine, desloratadine and fexofenadine) and molecules such as CAPE, Melatonin, Curcumin, Vitamin C, ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) profiles, density functional theory (DFT), molecular docking, biological targets and activities were compared by calculating. Since drug development is an extremely risky, costly and time-consuming process, the data obtained in this study will facilitate and guide future studies. It will also enable researchers to focus on the most promising compounds, providing an effective design strategy. Their pharmacological activity was carried out using computer-based computational techniques including DFT, molecular docking, ADMET analysis, biological targeting, and activity methods. The best binding sites of Desloratadine, Levocetirizine, Fexofenadine, CAPE, Quercetin, Melatonin, curcumin, Vitamin C ligands to Desmoglein 1, Human Histamine H1 receptor, IgE and IL13 protons were determined by molecular docking method and binding energy and interaction states were analyzed. Fexofenadine and Quercetin ligand showed the most effective binding affinity. Melatonin had the best Caco-2 permeability PPB values of Quercetin, CAPE and Curcumin were at optimal levels. On the OATP1B1 and OATP1B3 of curcumin and CAPE, Quercetin was found to have strong inhibition effects on BCRP. Melatonin and CAPE were found to have the highest inhibition values on CYP1A2, while CAPE had the highest inhibition values on CYP2C19 and CYP2C9. Vitamin C and Quercetin were found to be safer in terms of cardiac toxicity and mutagenic risks, while Desloratadine and Levocetirizine carried high risks of neurotoxicity and hematotoxicity, while CAPE was noted for its high enzyme inhibitory activities and low toxicity profiles, while the hERG blockade, DILI, and cytotoxicity values of other compounds pointed to various safety concerns. This study demonstrated the potential of machine learning methods in understanding and discovering H1 receptor blockers. The results obtained provide important clues in the development of important strategies in the clinical use of H1 receptor blockers. In the light of these data, CAPE and Quercetin are remarkable molecules.
Comparison of Orexigenic and Anorexigenic Neuropeptide Levels in Hyperemesis Gravidarum Patients With Normal Pregnant Women: a Prospective Cohort Study
(Lippincott Williams & Wilkins, 2024) Yilmaz, Mehmet; Aksin, Serif; Balsak, Deniz; Aboalhasan, Yasmin; Batmaz, Ibrahim
Background: The aim of this study was to determine whether orexigenic neuropeptides, orexin and galanin, and anorexigenic neuropeptides, alpha-melanocyte-stimulating hormone (alpha-MSH) and cocaine- and amphetamine-regulated transcript (CART), are implicated in hyperemesis gravidarum (HG). Methods: Fifty pregnant women who had been diagnosed with HG between April 2022 and February 2023 at the Siirt University Faculty of Medicine Training and Research Hospital (tertiary center) were recruited for this study. An equal number of pregnant women without an HG diagnosis were included in the study as the control group. Participants' age, pregnancy history, medical history, thyroid function test results, complete blood count results, and electrolyte levels were recorded, and their orexin, galanin, alpha-MSH, and CART serum levels were analyzed using an enzyme-linked immunosorbent assay. Results: No statistically significant differences in orexigenic neuropeptides (orexin and galanin) were observed between the HG and control groups. A statistical difference was found between an anorexigenic neuropeptide (alpha-MSH) and the control group (P = .012). Based on a receiver operating characteristic analysis, the alpha-MSH parameter was statistically significant for distinguishing between participants with an HG diagnosis and those without, with a sensitivity of 63.6%, specificity of 65.9%, and cutoff value of 11769.3 pg/mL (P = .012, area under curve: 0.655). Based on the severity classification of ketonuria (ketonuria levels of +1 or +2 were classified as mild, whereas levels of +3 or +4 were classified as moderate to severe), the anorexigenic CART neuropeptide was found to be a statistically significant diagnostic indicator of severe ketonuria (P = .020). Conclusion: alpha-MSH and CART levels were found to be related in HG patients and in HG patients with severe ketonuria.
