    Alyssum filiforme Bitkisinin Antimikrobiyal, Antibiyofilm, Antioksidan Aktivitesinin ve Fenolik Profilinin Belirlenmesi
    (2023) Orçan, İlayda; Bülbül, Ali Savaş; Kara, Yakup
    Öz ? Bakteriler antibiyotiklere ve türevlerine karşı günden güne direnç kazanmaktadır ve bu küresel bir sorun haline gelmektedir. Bitkilerde bulunan sekonder metabolitlerin (fenolik bileşikler, flavonoidler, alkoloidler gibi) antioksidan ve antimikrobiyal gibi çeşitli aktiviteleri sebebiyle bu küresel sorunun önüne geçilebileceği düşünülmektedir. Bu kapsamda çeşitli çalışmalar yapılmış ve halen de yapılmaktadır. Bitkisel kaynaklardan antioksidan, antimikrobiyal ve anti-biyofilm gibi etki gösteren bileşenlerin belirlenmesi ile antibiyotik ve türevlerine karşı oluşan direnç aşılabilir. B vitamini ve magnezyum açısından zengin olan Brassicacea ailesinin bir üyesi de Alyssum filiforme türüdür. Alyssum filiforme bu kapsamda değerlendirilebilecek potansiyele sahip bir endemik türdür. Bu çalışmada; endemik olarak yetişen türün antimikrobiyal, anti-biyofilm, antioksidan ve RP-HPLC-PDA ile fenolik profili belirlendi. Elde edilen ekstre antimikrobiyal aktivite için Minimum İnhibisyon Konsantrasyonu (MIC) ve Minimum Bakterisidal Konsantrasyonu (MBC) yöntemleri uygulandı, antioksidan aktiviteyi belirlemek için ise 2,2-difenil-1-pikrilhidrazil (DPPH) radikalini temizleme aktivitesi ve demir indirgeme antioksidan güç (FRAP) metodları kullanıldı. Biyofilm oluşumunu önlemedeki etkinliği gözlemleyebilmek için kristal viyole bağlama yöntemi kullanıldı. Tüm bakterilerde olumlu sonuçlar elde edildi. FRAP ve DPPH sonuçları sırasıyla 13.070 ?mol FeSO4.7H2O/g ve SC50 5.190 mg/ml olarak belirlendi. Elde edilen fenolik analiz sonucunda bitkinin kafeik asit ve krisin yönünden zengin olduğu bulundu. Elde edilen sonuçlar ışığında Alyssum filiforme türünün sağlık açısından değerli bir tür olduğu düşünülmektedir.

    ANTIBACTERIAL, ANTIFUNGAL, ANTIBIOFILM, ANTIOXIDANT, AND ANTICANCER PROPERTIES OF METHANOL EXTRACTS OF SOME ACANTHOLIMON BOISS (PLUMBAGINACEAE) SPECIES
    (2023) Bostancı, Maside Temiz; Bülbül, Ali Savaş; Uygun, Cihangir; Bekmezci, Muhammed; Bayat, Ramazan; Şen, Fatih
    Therapeutic properties of plants have been used since the existence of mankind. To benefit from this feature, the discovery of the active components of plants has gained momentum today. One of these plant species is Acantholimon Boiss. This plant extract has antifungal, antimicrobial, and anticancer properties. In this article, antimicrobial, antifungal and antioxidant capacities and antibiofilm properties of Acantholimon Boiss plant extract on 15 bacterial and 2 fungal species were evaluated. Antimicrobial properties were evaluated by Agar Well Diffusion method. It was observed that the plants formed a zone diameter of 12-18 cm. Minimum Inhibition Concentration (MIC) and Minimum Bactericidal Concentration (MBC) tests were used to determine the minimum active property. Biofilms of almost all bacteria were reduced by 10-50% by Acantholimon species at doses of 8 mg/ml-16 mg/ml. For MCF-7 cells, the IC50 values for A. acerosum subsp. brachystachyum (Boiss. ), A. acenum var. balansae, A. armenum var. balansae and A. kotschyi were 0.143 mg/ml, 0.63 mg/ml, 0.63 mg/ml, 0.63 mg/ml, 0.63 mg/ml, 0.63 mg/ml and 0.107 mg/ml, respectively. The same doses did not show a cytotoxic effect on HUVEC cell lines. With this article, it has given important results in terms of having a wide range of bacterial studies and examining its activities in fungi and cell lines. These findings suggest that extracts of Acantholimon Boiss species may be a potential source of natural medicines and antibacterial, antifungal, antibiofilm, antioxidant, and anticancer activities may support their therapeutic use.

    Investigation of the relationship between orthorexic tendencies and some anthropometric measurements and variables in university students
    (2024) Erkılıç, Tugçe Orkun; Bayraktar, Bülent; Erkılıç, Ali Ozan; Ozcan, Gulbahar Boyuk; Bozok, Ümmü Gülşen; Bülbül, Ali Savaş; Turan, Merve
    Orthorexia nervosa (ON) is a type of eating disorder marked by an excessive preoccupation with eating healthily to preserve and promote health, which surpasses normal levels of concern. This study aims to investigate the correlation between orthorexic tendencies, anthropometric measurements, and several other characteristics among university students. A cross-sectional study was done with a sample size of 307 university students from various departments, consisting of 228 females and 79 males. The data-gathering process consisted of administering a demographic information form and the ORTO-11 questionnaire. Anthropometric measurements, such as weight, height, waist circumference, hip circumference, and chest circumference, were measured. In addition, Body Mass Index (BMI) was calculated. The TANITA BC-418 equipment was used to measure the weight of the participants, while a flexible tape measure was used to measure their height, waist circumference, hip circumference, and chest circumference. The BMI was calculated by the individual's weight (in kilograms) by the square of their height (in meters). The data analysis encompassed the utilization of descriptive statistics, t-tests, variance analysis, and Pearson correlation analysis. A score of 25 or lower on the ORTO-11 scale was categorized as orthorexic, whereas a score higher than 25 was deemed normal. The average age and orthorexia scores of the subjects were 20.81±1.86 and 27.76±4.42 for females, and 21.38±4.14 and 28.11±4.37 for males, respectively. It was determined that 29.3% of the participants were found to display orthorexic tendencies, while the remaining 70.7% did not. There were no statistically significant variations in age, hip circumference, and orthorexia scores across genders (p>0.05). No statistically significant relationship was found between the total orthorexia scores and BMIs of the individuals (r=-.051, p>0.05). ON is associated with psychological and social complications, which in turn contribute to the development of disordered eating patterns. The results of this study indicate that determining the frequency of orthorexic tendencies among university students may contribute to the development of strategies for its prevention.

    Silver nanoparticle synthesis by biogenic reduction method and investigation of antimicrobial, antibiofilm, anticancer activities
    (2023) Karakaya, Funda; Bülbül, Ali Savaş; Bekmezci, Muhammed; Şen, Fatih
    In this study, R. aculeatus plant extract and biogenically formed AgNPs were investigated for their potential antibacterial, antibiofilm and anticancer abilities. AgNPs were characterised using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and UV-vis spectroscopy (UV-VIS). According to the Debye Scherrer formula, the particle size was found to be 32.56 nm. Disc diffusion and microdilution methods were used to investigate the antibacterial activity. In the disc diffusion study, the best results were obtained from the extract and AgNP. In the tests using plant extracts, Staphylococcus aureus ATCC 25923 showed the lowest antibiofilm activity, while Bacillus subtilis and Enterobacter aerogenes ATCC 13048 showed the highest activity. Salmonella infantis was most affected by AgNP, while Escherichia coli CFAI ATCC 25922 was least affected. Biogenically synthesised AgNPs were also investigated in cytotoxic activity studies. It was found to have the lowest concentration value on MCF-7 and HUVEC cell lines at the determined concentrations. The extract did not have any cytotoxic effect on MCF-7 cell line. HUVEC cell line showed the lowest cytotoxic activity of $10^{-3}$ g/mL. The antibacterial, antibiofilm and anticancer properties of R. aculeatus plant extract and biogenically produced AgNPs have been the subject of an important study. Furthermore, the comparison of the effects of plant extract and AgNPs on breast cancer cell lines and healthy cell lines provides a rich scientific material.
