A Comparison of Native and Syrian Immigrant Women Students' Genital Hygiene Behaviors: A Cross-Sectional Study
(Univ Sao Paolo, 2025) Icke, Sibel; Cifci, Sema
Objective: This study aims to compare the genital hygiene behaviors of native and Syrian immigrant women students. Method: This was cross-sectional research. The sample size of the study was determined via power analysis and G*Power software. A total sample size of 330 individuals was equally distributed to both groups. Sociodemographic Characteristics Questionnaire" and the 'Genital Hygiene Behaviors Scale' were used as data collection tools. Results: There was a significant difference between the mean scores of the scales of both student groups (p < 0.05). The mean scores of native students were found to be higher. The variables "how to clean the genital area", "material used for genital hygiene", "washing method of underwear", "pretoilet hand washing habits" and "regular menstruation" were found to be most effective in terms of the mean scores of the Genital Hygiene Behaviors Scale and its subscales for immigrant students. Conclusion: Social security status and nationality were the most influential sociodemographic factors affecting genital hygiene behaviors. It would be beneficial to raise awareness and promote behavioral changes regarding genital hygiene through seminars, conferences, workshops, and similar events targeting all women university students.

A Rare Cause of Dysphagia: A Giant Ganglioneuroma in Parapharyngeal Space
(Springer, 2022) Aslan, Mehmet; Dogukan, Fatih Mert
Parafarengeal ganglioneuroma is a very rare benign tumor originating from the sympathetic nervous system that produces mass and functional effects. Ganglioneuroma is most commonly caused by the posterior mediastinal, retroperitoneal area and adrenal glands. Generally, they do not present any additional signs or symptoms other than mass. Horner’s syndrome may sometimes occur due to the compression of the sympathetic chain. A 41-year-old male patient with a long-standing mass in the lateral compartment of the left neck was admitted to our clinic. The patient was operated, and the pathological result of the mass was reported as ganglioneuroma. We present a rare case of ganglioneuroma in paraphryngeal space by reviewing the current literature. © 2022 Elsevier B.V., All rights reserved.

A Rare Cause of Dysphagia: Giant Lipoma in Parapharyngeal Space
(Lippincott Williams and Wilkins, 2020) Aslan, Mehmet; Ozer Ozturk, Ebru; Dogukan, Fatih Mert
Background: Parapharyngeal area is one of the most complex areas of head and neck anatomy. Tumors of the parapharyngeal region are very rare among head and neck tumors. Lipomas also constitute a tiny proportion of parapharyngeal tumors so parapharyngeal area lipomas are very rare in the literature. Due to anatomical location, these tumors treatment is challenging. Clinical Report: A 20-year-old male patient admitted to our department with complaints of swallowing difficulty and a mass on the right side of the neck. Magnetic resonance imaging was performed, and it was reported as a 6 4.5 cm lipoma. He underwent excision of parapharyngeal area lipoma by a transoral approach. Conclusion: Parapharyngeal lipomas are very rare, and difficult to diagnose before they turn out symptomatic. The primary treatment approach in tumors of the parapharyngeal area is surgery and the surgical approach should be chosen according to the anatomical location of the lesion. © 2021 Elsevier B.V., All rights reserved.
Ability of Cha2ds2-vasc/R2cha2ds2-vasc Scores To Predict Complications Related To Cardiac Implantable Electronic Devices
(Wiley, 2025) Aktan, Adem; Kilic, Raif; Guzel, Hamdullah; Tastan, Ercan; Oksul, Metin; Guzel, Tuncay; Soner, Serdar
BackgroundGlobally, the number of cardiac implantable electronic devices (CIEDs) is increasing. In our study, we aimed to investigate whether CHA(2)DS(2)-VASc and R(2)CHA(2)DS(2)-VASc scores are predictive of CIED-related complications. MethodsOur investigation was carried out with a multicenter retrospective design. Patients who underwent CIED surgery at two cardiac centers in Turkey between January 2011 and May 2023, 1676, were evaluated. The patients were divided into two groups according to their R(2)CHA(2)DS(2)-VASc scores. Patients with R(2)CHA(2)DS(2)-VASc >= 5 were included in group 1 (380 patients), and patients with R(2)CHA(2)DS(2)-VASc < 5 (1296 patients) were included in group 2. The primary outcome was defined as the cumulative events. Each component of cumulative events, such as hematoma, pericardial effusion, pneumothorax, and infection, was also defined as a secondary outcome. ResultsThe study's patient population had an average age of 62.9 +/- 14 years. Pneumothorax (1.8% vs. 1.3%, p = 0.444), pericardial effusion or tamponade (0.35% vs. 0.2%, p = 0.659), and clinically significant hematoma (1.1% vs. 0.6%, p = 0.376) were comparable between the groups. Infection-related devices and cumulative events classified as primary outcomes were higher in the R(2)CHA(2)DS(2)-VASc >= 5 group (6.1% vs. 1.2%, p < 0.001; 7.6% vs. 3.2%, p < 0.001, respectively). Modeling analyses showed that the CHA(2)DS(2)-VASc score and HT were also independent predictors of device-related infection and cumulative events. ConclusionIn the R(2)CHA(2)DS(2)-VASc >= 5 groups, infection related to the device system and cumulative events were higher. Patients with an R(2)CHA(2)DS(2)-VASc score of 5 or more and a high CHA(2)DS(2)-VASc score should be evaluated more carefully regarding infection and cumulative events before and after the operation.

(IEEE, 2018) Zan, Hasan; Yildiz, Abdulnasir
Phonocardiogram is used for ambulatory diagnostic to assess health status of heart and detect cardiovascular disease. The goal of this study is to develop automatic classification method of PCG recordings collected from different databases and recorded in a different way. For this purpose, after various time and frequency domain features are extracted from PCG recordings obtained from two databases, recordings are subjected to pre-classification in order determine which database they are obtained from. Before final classification, various time, frequency and time-frequency domain features of classified recordings are extracted. These features are fed into four different classification ensembles trained with training dataset. With final decision rule, proposed algorithm achieved an accuracy of 98.9%, a sensitivity of 93.75% and a specify of 99.5%.
Abu Ubayd’s Understanding Of Naskh;
(Hitit Univ, 2022) Yasar, Mehmet Aziz; Nas, Taha
In the period when Islamic sciences were formed, a large number ofscholars with absolute ijtihad capacity were trained. One of the scholars mentioned is Abu `Ubayd al- Qasim ibn Sallam al-Khurasani al-Harawi 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 Ebu Ubeyd as a follower of Imam Shafii. On the other hand, some Hanbali scholars have mentioned Ebu Ubeyd among the class of Hanbali scholars. However, it was concluded that it would be more correct to see Ebu 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. Ebu 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-Nasih ve'l-mensu. fi'l-kur.ani'l-aziz ve ma fihi mine'l-fera'iz ve's-sunen. While revealing Ebu Ubeyd's understanding of naskh, his work en-Nasi. ve'l-mensu. was used as the main source. In addition to this, his other works related to the subject, especially his work called Kitabu'l- emval, 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, Ebu 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. Ebu 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, tabi`in and early convert scholars. However, although Ebu 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 Ebu 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 Ebu 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. Ebu 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 ahad sunnah with its own like, no example has been encountered of the naskh of the ahad sunnah with its own like or with ahad and the ahad sunnah with the mutawatir sunnah. As it can be understood from my statements on the subject, Ebu 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.
Acceptance of Diversity, Social Media Use, and Labeling of Refugees in Türkiye: A Mediation Analysis From a Social Work Perspective
(Routledge Journals, Taylor & Francis Ltd, 2025) Aslan, Yavuz; Kocak, Orhan; Kus, Yagmur; Hizmetci, Nimet Sagir
This study examines the relationships between acceptance of diversity, social media use, and the labeling of refugees in T & uuml;rkiye, focusing on the mediating role of social media use. Grounded in Goffman's Labeling Theory and approached from a social work perspective, the study utilized a cross-sectional, correlational design. Data were collected from 431 participants via an online survey. Confirmatory factor analysis and structural equation modeling were employed to analyze the data. The findings revealed that acceptance of diversity was negatively associated with social media use and the labeling of refugees, while social media use was positively associated with refugee labeling. Moreover, social media use mediated the relationship between acceptance of diversity and labeling. These results underscore the dual role of social media as both a space for intercultural communication and a platform for spreading exclusionary narratives. The study contributes to the literature by highlighting the importance of promoting inclusive digital environments. It provides practical implications for developing anti-discriminatory interventions within social work practice and media literacy programs.

Accumulation Potential of Lead and Cadmium Metals in Maize (Zea mays L.) and Effects on Physiological-Morphological Characteristics
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Elik, Ümit; Gul, Zeynep Dumlu
Phytoremediation stands at the forefront of modern environmental science, offering an innovative and cost-effective solution for the remediation of heavy-metal-contaminated soils through the natural capabilities of plants. This study aims to investigate the effects of lead (Pb) and cadmium (Cd) metals on plant growth (e.g., seedling height, stem diameter, fresh and dry weight), physiological properties (e.g., tissue relative water content, tissue electrical conductivity), and biochemical parameters (e.g., chlorophyll content, superoxide dismutase (SOD), catalase (CAT), peroxidase (POD) enzyme activities) of maize compared to the control group under greenhouse conditions at the Atatürk University Plant Production Application and Research Center. The results show that plant height decreased by 20% in the lead (Pb3000) application and by 42% in the cadmium (Cd300) application compared to the control group. The highest Pb dose (Pb3000) caused a 15% weight loss compared to the control, while the highest Cd dose (Cd300) caused a weight loss of 63%. The accumulation rates of heavy metals in soil, roots, and aboveground parts of plants indicated that maize absorbed and accumulated more Cd compared to Pb. © 2025 Elsevier B.V., All rights reserved.

Cancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.

(Soc Argentina Pediatria, 2024) Talay, Mehmet N.; Gungor, Emre; Orhan, Ozhan; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Introduction : Cyanide poisoning, whether it be accidental or intentional, remains a significant danger to adults and children, especially in societies where agriculture is a primary source of income. We examined the clinical follow-up, complications, and results of cyanide poisoning cases that occurred after eating the pits and seeds of plants containing cyanide glycosides, such as apricot kernels and almonds. Methods : Between 01/01/2017 and 01/08/2022, 14 children aged 1-18 years who were followed up with a prediagnosis of cyanide poisoning in our Paediatric Intensive Care Unit (PICU) were retrospectively analysed. Results : Eight of the patients followed with a preliminary diagnosis of cyanide poisoning were female and six were male. The most common admission month was July (42.8%) coinciding with the agricultural season. The most common symptoms at presentation were weakness and fatigue (n = 7). In the PICU, 4 patients presented lip cyanosis; 3, altered level of consciousness. Vomiting, seizure, headache, dizziness and palpitatons were less frequent. Four patients were treated with hydroxocobalamin (Cyanokit (R) ) as an antidote due to acidosis in their blood gases. All patients treated for cyanide poisoning were discharged. Conclusions : Cyanide poisoning should be considered in paediatric patients with suspicious findings, sudden loss of consciousness, increased anion gap acidosis and lactic acidosis. The history of eating the seeds of plants such as apricot and almonds should be investigated .

Acute Toxicity of Deltamethrin on the Fatty Acid Composition of Phospholipid Classes in Liver and Gill Tissues of Nile Tilapia
(Springer Int Publ Ag, 2017) Cengiz, E. I.; Bayar, A. S.; Kizmaz, V.; Bashan, M.; Satar, A.
Deltamethrin is a pyrethroid pesticide contaminating aquatic ecosystems. The purpose of this study was to clarify the acute toxicity of deltamethrin on the fatty acids of phospholipid (PL) classes in liver and gill of Nile tilapia. The fatty acids of PL classes were analyzed by gas chromatography. Deltamethrin brought about differences in the fatty acids of the PL classes in the liver and gill. In the liver of exposed fish, 16:0, 18:2(n-6), 22:6(n-3) in phosphatidylcholine (PC); 16:0, 18:1(n-9), 18:2(n-6), 20:4(n-6), 22:6(n-3) in phosphatidylethanolamine (PE); 16:0, 18:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) in phosphatidylinositol (PI) and in phosphatidylserine (PS) 16:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) were the affected fatty acids. There were significant alterations in Sigma MUFAs (monounsaturated fatty acids), a(n-3)PUFAs (polyunsaturated fatty acids) and Sigma(n-6)PUFAs in PC; Sigma SFAs (saturated fatty acids), Sigma MUFAs, Sigma PUFAs, Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PE; Sigma SFAs, Sigma MUFAs, Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PI and Sigma SFAs, Sigma MUFAs,Sigma PUFAs and Sigma(n-3)PUFAs in PS. In the gill, 18:2(n-6), 20:4(n-6), 22:6(n-3) in PC; 16:0, 18:1(n-9), 20:4(n-6), 22:6(n-3) in PE; 16:0, 18:0, 18:1(n-9), 18:2(n-6) in PI and in PS 16:0, 18:0,18:1(n-9), 20:3(n-6), 20:5(n-3), 22:6(n-3) affected. The alterations in Sigma SFAs, Sigma MUFAs, Sigma PUFAs and Sigma(n-6)PUFAs in PC; Sigma SFAs, Sigma MUFAs, Sigma PUFAs, Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PE; Sigma(n-3)PUFAs and Sigma(n-6)PUFAs in PI; Sigma SFAs, Sigma MUFAs, Sigma PUFAs, Sigma(n-3) PUFAs and Sigma(n-6)PUFAs in PS were significant in gill. The changes in the fatty acids of the PL classes in response to deltamethrin can influence structure and functions of the membrane systems. Changes in fatty acids may be one defense mechanism against the deltamethrin.

Adaptation of the Vicarious Resilience Scale To Turkish: a Validity and Reliability Study
(Educational Publishing Foundation - American Psychological Assoc, 2025) Topcu, Feyza; Boz, Canahmet; Seneldir Patolo, Ayse; Kitapcioglu, Sureyyanur; Isiker-Bedir, Deniz; Sanyar, Sema
Objective: The 27-item Vicarious Resilience Scale (VRS) is the first tool developed to measure vicarious resilience in mental health professionals working with trauma survivors. Given that the VRS measures the positive impact on therapists resulting from observing the healing process of trauma victims, it is especially significant to evaluate its validity and reliability in Turkish culture. This study aims to adapt the VRS to Turkish and examine its psychometric properties. Method: VRS was adapted and administered via electronic survey to 337 mental health professionals from around the globe working with survivors of severe traumas, such as earthquake survivors. The validity of the VRS was examined using different techniques: confirmatory factor analysis (CFA) and criterion-related validity. Result: CFA yielded seven factors that were consistent with the original form: changes in life goals and perspective, client-inspired hope, increased recognition of clients' spirituality as a therapeutic resource, increased capacity for resourcefulness, increased self-awareness and self-care practices, increased consciousness of power and privilege relative to clients' social location, and increased capacity for remaining present while listening to trauma narratives. The Cronbach's alpha reliability of the VRS was found to be .95; it displayed positive correlations with posttraumatic growth, psychological resilience, and quality of life, indicating convergent validity. However, it had a negative correlation with depression, anxiety, and stress, indicating discriminant validity. Conclusion: The VRS is a valid and reliable measurement scale by professionals working with trauma survivors to aid the recognition and cultivation of vicarious resilience in Turkish mental health professionals.

Adolescent Transport and Unintentional Injuries: a Systematic Analysis Using the Global Burden of Disease Study 2019
(Elsevier Sci Ltd, 2022) Peden, Amy E.; Cullen, Patricia; Francis, Kate Louise; Moeller, Holger; Peden, Margaret M.; Ye, Pengpeng; Ivers, Rebecca Q.
Background Globally, transport and unintentional injuries persist as leading preventable causes of mortality and morbidity for adolescents. We sought to report comprehensive trends in injury-related mortality and morbidity for adolescents aged 10-24 years during the past three decades. Methods Using the Global Burden of Disease, Injuries, and Risk Factors 2019 Study, we analysed mortality and disability-adjusted life-years (DALYs) attributed to transport and unintentional injuries for adolescents in 204 countries. Burden is reported in absolute numbers and age-standardised rates per 100 000 population by sex, age group (10-14, 15-19, and 20-24 years), and sociodemographic index (SDI) with 95% uncertainty intervals (UIs). We report percentage changes in deaths and DALYs between 1990 and 2019. Findings In 2019, 369 061 deaths (of which 214337 [58%] were transport related) and 31.1 million DALYs (of which 16.2 million [52%] were transport related) among adolescents aged 10-24 years were caused by transport and unintentional injuries combined. If compared with other causes, transport and unintentional injuries combined accounted for 25% of deaths and 14% of DALYs in 2019, and showed little improvement from 1990 when such injuries accounted for 26% of adolescent deaths and 17% of adolescent DALYs. Throughout adolescence, transport and unintentional injury fatality rates increased by age group. The unintentional injury burden was higher among males than females for all injury types, except for injuries related to fire, heat, and hot substances, or to adverse effects of medical treatment. From 1990 to 2019, global mortality rates declined by 34.4% (from 17.5 to 11.5 per 100 000) for transport injuries, and by 47.7% (from 15.9 to 8.3 per 100000) for unintentional injuries. However, in low-SDI nations the absolute number of deaths increased (by 80.5% to 42 774 for transport injuries and by 39.4% to 31 961 for unintentional injuries). In the high-SDI quintile in 2010-19, the rate per 100 000 of transport injury DALYs was reduced by 16.7%, from 838 in 2010 to 699 in 2019. This was a substantially slower pace of reduction compared with the 48.5% reduction between 1990 and 2010, from 1626 per 100 000 in 1990 to 838 per 100 000 in 2010. Between 2010 and 2019, the rate of unintentional injury DALYs per 100 000 also remained largely unchanged in high-SDI countries (555 in 2010 vs 554 in 2019; 0.2% reduction). The number and rate of adolescent deaths and DALYs owing to environmental heat and cold exposure increased for the high-SDI quintile during 2010-19. Interpretation As other causes of mortality are addressed, inadequate progress in reducing transport and unintentional injury mortality as a proportion of adolescent deaths becomes apparent. The relative shift in the burden of injury from high-SDI countries to low and low-middle-SDI countries necessitates focused action, including global donor, government, and industry investment in injury prevention. The persisting burden of DALYs related to transport and unintentional injuries indicates a need to prioritise innovative measures for the primary prevention of adolescent injury.

The Adsorption and Inhibition Efficiency of 2-Amino for Corrosion of Mild Steel in Hydrochloric Acid Solution
(Emerald Group Publishing Ltd, 2023) Okten, Veysi; Yildiz, Resit; Sigircik, Goekmen; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
PurposeThis study aims to prevent mild steel (MS) against corrosion in 0.5 M HCl solution, 2-amino-4-methoxy-6-methyl-1,3,5-triazine was used. The effectiveness of the compound as a corrosion inhibitor was studied via electrochemical, surface and theoretical calculation techniques. Design/methodology/approachFor concentrations ranging from 0.5 to 10.0 mM, almost similar polarization resistances were obtained from electrochemical impedance spectroscopy (EIS) and linear polarization resistance tests. It also investigated inhibitive activity of 2-amino-4-methoxy-6-methyl-1,3,5-triazine on the steel surface using scanning electron and atomic force microscope instruments. Langmuir adsorption is the best matched isotherm for the adsorption of the inhibitor to the steel surface. FindingsEIS method was used to determine inhibition efficiency, which was determined to be 95.7% for 10.0 mM inhibitor containing acid solution. Density functional theory's predictions for quantum chemistry agreed well with the other experimental results. Originality/valueThe methods used in this study are effective and applicable; the used organic inhibitor is 2-amino-4-methoxy-6-methyl-1,3,5-triazine; and protective effectiveness is important, which is crucial for the task of MS corrosion prevention.

Adsorption Behaviors of Malachite Green by Using Crosslinked Chitosan/Polyacrylic Acid/Bentonite Composites with Different Ratios
(Elsevier, 2020) Yildirim, Ayfer; Bulut, Yasemin
In this study, by using different quantities of methylenebisacrylamide (MBA) and acrylic acid (AA), chitosan/polyacrylic acid/bentonite composites (CCS/PAA/BNTs) were synthesized and used for the adsorption of malachite green (MG). The fourier transmission infrared spectra, thermogravimetric analysis-differential thermal analysis and scanning electron microscopy techniques were used to determine synthesized composites. The effects of initial concentration, contact time, temperature and pH were investigated. Kinetic studies indicated that, due to the pseudo-second order model, correlation coefficients (R-2 >0.98) were the best fit thus, by using k(ps), the activation energies (E-a) were calculated (19.06, 15.64, 19.49, 8.29, 24.53 kJmol(-1)). The equilibrium data of MG agreed with the Langmuir model. The highest adsorption capacity calculated was found as 384.62-454.55 mgg(-1) for MG adsorption at 298-318 K. Thermodynamic studies demonstrated that MG adsorption was endothermic, caused spontaneous reaction and increased the entropy between 298-318 K. The adsorption reactions of MG were revealed as physisorption (Delta H<80 kJmol(-1)). The optimum pH was found as 6. The CCS/PAA/BNT2 composite indicated the highest adsorption capacity and best thermal stability compared to the other composites. (C) 2019 Elsevier B.V. All rights reserved.

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.

Adsorptive Performance of Magnetic Nano-Biosorbent for Binary Dyes and Investigation of Comparative Biosorption
(Springer international Publishing Ag, 2019) Tarhan, Tuba; Tural, Bilsen; Boga, Kenan; Tural, Servet
The individual and competitive biosorption capacities of Metanil Yellow (MY) and Reactive Black 5 (RB5) by glutaraldehyde cross-linked magnetic chitosan nanoparticles (GMCNs) were studied. Competitive biosorption of the MY and RB5 dyes by the GMCNs has never been reported previously. Fourier transform infrared technique has been used to show the biosorbed MY and RB5 dyes onto GMCNs. During the studies, various essential factors influencing the biosorption, like adsorbate concentration, pH of the solution and contact time have been monitored.The equilibrium was achieved within 17 h for single dyes and 3 h for binary mixture at pH 3. The biosorption capacities were 620 mg/g for dye MY and 2549 mg/g for dye RB5 at pH 3, 30 degrees C. The second-order kinetic model has good compatibility with the dynamical biosorption behavior of a single dye and binary mixture. In order to study the competition biosorption of the RB5 and MY dyes in mixture solutions, the intraparticle diffusion model was used. Competition biosorption through analysis of the intraparticle diffusion model apparently favored the RB5 dye more than the MY dye on the GMCNs in mixture solutions. The biosorbent was regenerated efficiently through the alkaline solution and was then reused ten times for biosorption-desorption cycles.

Nanovaccines are considered a new approach in vaccination methodology specially for Covid-19 infection. Nanovaccines are more effective than conventional vaccines; Because ofhumoral and cellular immune responses which are simultaneously induced. Nano vaccines are assumed to upregulate the immune system as well as infection prevention. They are probably promising candidates for chronic autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, AIDS, and COVID-19 infectious. Based on this, we will describe the different working mechanisms of nanoparticles. In addition, applicable nano vaccines which have been approved for COVID-19 therapy Covid 19 are described. Antigen-carrying nanoparticles can affect the immune response and significantly enhance cell-T cytotoxic response. Nanoscale particles can improve vaccine efficiency because of their biomedical benefits. These properties include Small size, which allows better penetration into tumors and more half-life tumor cells. Current vaccines, however, are required to re-formulate almost because of gradual antigen modifications. More ever these vaccines do not protect against mutations and the low half-life of current vaccines due to limitations of current technologies. Nano vaccine formulation improvements have been required to induce a widespread and potent immune response. In this review, we provide an overview ofthe types and applications of nanoparticles in vaccines and their outstanding properties that made them alternatives for Covid-19 treatment. © 2023, Bentham Books imprint.

Aflatoxin M1 in Human Breast Milk in Southeastern Turkey
(Springer Heidelberg, 2017) Altun, Serap Kilic; Gurbuz, Semra; Ayag, Emin
This study was performed to determine aflatoxin M-1 (AFM(1)) in human breast milk samples collected in AanlA +/- urfa, located in Southeastern region of Turkey, and to investigate a possible correlation between AFM(1) 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 AanlA +/- urfa, Turkey, were analyzed using competitive enzyme-linked immunosorbent assay (ELISA) for the presence of AFM(1). AFM(1) 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 AFM(1) 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.
