Article Citation - WoS: 2Citation - Scopus: 3Activated Carbon-Coated Iron Oxide Magnetic Nanocomposite (ionps@ctac) Loaded With Morin Hydrate for Drug-Delivery Applications(Frontiers Media Sa, 2024) Dogan, Yusuf; Ozic, Cem; Ertas, Erdal; Baran, Ayse; Rosic, Gvozden; Selakovic, Dragica; Eftekhari, Aziz; Doğan, Yusuf; Baran, Ayşe; Department of Plant Protection / Bitki Koruma BölümüCancer 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.Article Citation - WoS: 0Citation - Scopus: 0Antioxidant Properties of allium Turcicum Özhatay & Cowley Plant Extract, Its Effects on the Proliferation and Migration of Cancer Cells(Frontiers Media Sa, 2024) Baran, Ayşe; Baran, Mehmet Fırat; Cebe, Deniz Baris; Ahmadian, Elham; Eftekhari, Aziz; Baran, Mehmet Firat; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri BölümüCancer is a type of non-communicable disease that is responsible for numerous deaths worldwide. Cancer incidence and mortality rates are on the rise due to a combination of factors, such as a growing population, aging, and poor dietary habits. The Allium turcicum & Ouml;zhatay & Cowley plant is an endemic plant in the area where it grows and is consumed by the public due to its various benefits. This endemic plant, which generally grows in high-altitude regions, is sold in bunches because it is costly, mixed with rock salt, crushed into powder, and consumed as a spice. The cytotoxic and growth-inhibitory effects of A. turcicum & Ouml;zhatay & Cowley herb extract on human glioblastoma U373 cells, human colorectal carcinoma cell HCT-116, and healthy HUVEC cell lines were determined by the MTT method. After 24 and 48 h of application, logIC50 values in HUVEC, HCT-116, and U373 cells were defined as 3.737, 3.765; 3.513, 3.696, 4.476, and 4.104 mu g/mL, respectively. We conducted a cell migration experiment to study the A. turcicum & Ouml;zhatay & Cowley Extract (AT & Ouml;CE) impact on cancer cells' metastatic behavior. Our findings indicate that AT & Ouml;CE has an inhibitory effect on the migration potential of the cells used in the study. We conducted experiments using DPPH, ABTS, CUPRAC, and total phenolic content to assess the antioxidant properties of AT & Ouml;CE. The findings from the antioxidant activity experiments revealed an activity level of 0.20 +/- 0.046 at IC50.

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.

(R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.Article Citation - WoS: 0Citation - Scopus: 0Green Synthesis and Characterization of Silver Nanoparticles Using Anchusa Officinalis: Antimicrobial and Cytotoxic Potential(Dove Medical Press Ltd, 2025) Keskin, Cumali; Baran, Mehmet Fırat; Baran, Ayşe; Baran, Ayse; Eftekhari, Aziz; Adican, Mehmet Tevfik; Mohamed, Ali Jimale; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri BölümüObjective: Anchusa officinalis L. (A. officinalis) is a herbaceous traditional medicinal plant used in the treatment of some diseases. The presence of its medicinal properties suggested that A. officinalis (AO) leaf extract could be used as a coating agent for the environmentally friendly production of silver nanoparticles (AgNPs). Methods: The synthesized biogenic silver nanoparticles (AO-AgNPs) were characterized using different techniques. The antimicrobial activity of AgNPs against common bacterial pathogenic strains was determined by the minimum inhibitory concentration (MIC) method. The presence of phytochemicals was determined by LSMS/MS. The MTT assay was used to investigate AO-AgNPs' cytotoxic activity in malignant (LnCap, Caco2, MDA-MB2, A549) and healthy (HEK-293) cell lines. Results: LC-MS/MS analysis detected the presence of rich phytochemicals that may be responsible for reduction reactions. Biogenic AO-AgNPs exhibited effective inhibition of the growth of pathogenic microorganisms at low concentrations. The most effective antimicrobial activity was measured as 0.5 mu g/mL MIC against S. aureus, E. coli, and C. albicans. Moreover, AO-AgNPs showed significant inhibition on the growth of cancerous cell lines, especially at a concentration of 25 mu g/mL. On the contrary, it was determined that the inhibition rate decreased in the growth of healthy cell lines due to the increase in concentration. The lowest EC50 values were determined as 15.15 mu g/mL in A549 cells. Conclusion: The obtained results showed that AO could be an important source for the synthesis of AgNPs. Especially their ability to inhibit the growth of antibiotic-resistant pathogenic bacteria at low concentrations compared to common antibiotics indicates that AOAgNPs can be used as biomedical agents in various areas. Moreover, their suppressive effect on cancerous cell lines showed that they have the potential to be used as an anticancer agent, but due to their proliferative effect on healthy cell lines, care should be taken in determining the appropriate dose.Article Citation - WoS: 0Citation - Scopus: 0Green Synthesis of Fe3o4-Crataegus Tanacetifolia (Lam.)

Radiation therapy (RT) is a modality for TNBC management. Radiosensitizers can mitigate the adverse effects of RT. Applying green-synthesized silver nanoparticles (Ag-NPs) from biological sources such as plants is a potential strategy to sensitize cancer cells to radiotherapy due to the low toxicity. Therefore, identifying novel natural sources for synthesizing stable and broadly applicable green-Ag-NPs has gained more attention in cancer therapy. In the present study, we synthesized green- Ag-NPs from pumpkin peel extract and elucidated the impact of green-synthesized Ag-NPs as a radiosensitizer in MDA-MB 231 cells (a model of TNBC). Results: The prepared Ag-NPs had a spherical shape with an average size of 81 nm and a zeta potential of - 9.96 mV. Combination of green-synthesized Ag-NPs with RT exhibited synergistic anticancer effects with an optimum combination index (CI) of 0.49 in MDA-MB-231 cells. Green-synthesized Ag-NPs synergistically potentiated RT-induced apoptosis in MDA-MB-231 cells compared to the corresponding monotherapies. Morphological features of apoptosis were further confirmed by the DAPI-TUNEL staining assay. HIF-1 alpha expression was decreased in cells subjected to combination therapy. Bax and p53 expression increased, whereas Bcl-2 genes decreased. Combination therapy significantly increased the protein level of PERK and CHOP while decreasing cyclin D1 and p-ERK/total ERK levels compared to monotherapies. Conclusion: These findings indicate the potential effect of green-synthesized Ag-NPs as a radiosensitizer for TNBC treatment.Article Citation - WoS: 11Citation - Scopus: 13Phytochemical Analysis and Biological Activity of corchorus Olitorius L.: Quantitative Analysis of Bioactive Compounds by Lc-ms/Ms, Antibacterial, Enzyme Inhibition, and Cytotoxic Activities(Elsevier Science inc, 2023) Baran, Ayşe; Erenler, Ramazan; Turkan, Fikret; Alma, Mehmet Hakki; Demirtas, Ibrahim; Baran, Ayse; Saltan, Fatma ZerrinIntroduction: Corchorus olitorius L. is a significant plant in folk medicine, therefore, research on phytochemistry with biological activity may reveal its potential use in drug development.

Among these silver nanoparticles are beneficial products used in many fields, especially in medicine, due to their antibacterial properties. This research aimed to produce silver nanoparticles (Ag NPs) that are both affordable and environmentally friendly. For this purpose, Ag NPs were quickly obtained from domestic waste components of the carrot plant (Daucus carota L.). The UV-vis spectrophotometric, TEM, AFM, FE-SEM, STEM, EDX, XRD, and DLS analyses were performed to determine the properties of the obtained Ag NPs. It has been found that their surface charge is -21.8 mV, with a maximum absorbance at a wavelength of 421.37 nm, spherical appearance, and an average size distribution of 85.41 nm. The anticancer and antibacterial activities of the produced Ag NPs were investigated by MTT and microdilution. The synthesized Ag NPs showed the most significant antimicrobial effect on Pseudomonas aeruginosa ATCC 27833 with microdilution and low concentration. However, they were also determined to be effective on Bacillus subtilis ATCC 11774 and on Candida albicans ATCC 10231 pathogenic strains. In fact, the effective concentrations of Ag NPs on these strains were significantly lower than the antibiotics used. Furthermore, aside from exhibiting a superior anticancer impact on CaCO-2 cancer cells, it was established that Ag NPs also had remarkable efficacy in inhibiting U118 and Skov-3 cancer cells.Article Citation - WoS: 0Citation - Scopus: 0A Study To Assess the Pharmacological Agent Potential of Gold Nanoparticles and Their Effects on Human Cancer Cells and Hospital Pathogens Using in Vitro Methods(Frontiers Media Sa, 2025) Baran, AyşeInterest in metal nanoparticles synthesised using green methods is growing steadily.

The inhibitory effects of Au NPs with these properties on hospital pathogens and human cancer cells were evaluated by microdilution, disk diffusion and MTT techniquesAs a result of the findings, it was determined that Au NPs have antibacterial, antifungal and anticancer potential as pharmacological agents under in vitro conditions.Article Citation - WoS: 0Citation - Scopus: 1Synthesis and Characterization of Activated Carbon-Supported Magnetic Nanocomposite (mnps-Olac) Obtained From Okra Leaves as a Nanocarrier for Targeted Delivery of Morin Hydrate(Frontiers Media Sa, 2024) Baran, Mehmet Fırat; Baran, Ayşe; Baran, Mehmet Firat; Baran, Ayse; Ahmadian, Elham; Eftekhari, Aziz; Yildiztekin, Mahmut; Department of Medical Services and Techniques / Tıbbi Hizmetler ve Teknikleri BölümüIntroduction The method of encapsulating the drug molecule in a carrier, such as a magnetic nanoparticle, is a promising development that has the potential to deliver the medicine to the site where it is intended to be administered. Morin is a pentahydroxyflavone obtained from the leaves, stems, and fruits of various plantsmainly from the Moraceae family exhibiting diverse pharmacological activities such as anti-inflammatory, anti-oxidant, and free radical scavenging and helps treat diseases such as diabetes, myocardial infarction and cancer.Methods In this study, we conducted the synthesis of a nanocomposite with magnetic properties by coating biocompatible activated carbon obtained from okra plant leaves with magnetic nanoparticles.Results Characterization of the synthesized activated carbon-coated magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, dynamic light scattering, and zeta potential. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (Colorectal), MCF-7 (breast), U373 (brain), T98-G (Glioblastoma) cancer cell lines, and human umbilical vein endothelial cells healthy cell line.Discussion We studied the loading and release behavior of morin hydrate in the activated carbon-coated magnetic nanocomposite. Activated carbon-coated magnetic nanocomposite carriers can show promising results for the delivery of Morin hydrate drugs to the targeted site.Article Citation - WoS: 0Citation - Scopus: 0Ultrastructural Characteristics Of Leishmania (l.)tropica (wright, 1903) and Cell-Parasite Relationships in Cutaneous Leishmaniasis. Light and Electron Microscopic Study(Academic Press inc Elsevier Science, 2025) Baran, Ayşe; Gasimov, Eldar K.; Mahmudov, Farid R.; Rzayev, Fuad H.; Khalilov, Rovshan; Eftekhari, Aziz; Baran, AyseA light and electron microscopic study of skin biopsies taken from 9 patients with ulcerative leishmaniasis of both sexes aged from 14 to 26 years in the territory of the Republic of Azerbaijan was carried out. Based on clinical, morphological and electron microscopic parameters, all patients were diagnosed with ulcerative cutaneous anthroponotic leishmaniasis (Leishmania (L.) tropica). Stained and unstained ultrathin (50-70 nm) sections were viewed and photographed using a JEM-1400 transmission electron microscope at an accelerating voltage of 80-120 kV. Analysis of data from light and electron microscopic studies at the ultrastructural level made it possible to describe the structure and identify the morphometric parameters of the amastigote form of the intracellular parasite. Besides, it was found that the distance between the plasmalemmas of the parasitophorous vacuoles and the parasite L. (L.) tropica is only 1 nm. This facilitates the passage of the necessary nutrients for the survival of this parasite. One of the important factors in the chronic course and relapse of leishmaniasis caused by L.(L.) tropica is the penetration of the amastigote stage into the cytoplasm along with macrophages, and also into fibroblasts with low phagocytic activity. Pathological changes (deformed nucleus, damage to plasmalemma, focal destruction of the cytoplasm structures, vacuolization, etc.) in the parasite L. (L.) tropica, localized in macrophages, were identified and described.
