Cancer 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. Additionally, the total phenolic content was measured to be 0.26 +/- 0.044 mg GAE/g.

Background: Corrosion occurs wherever metal and its alloys exist. Protection of metals with corrosion inhibitor is a popular topic. Considering environmental concerns and human health, it is more favorable to use green corrosion inhibitors than traditional corrosion inhibitors. Methanol extract of Arum dioscoridis (AD) becomes a potential green corrosion inhibitor and it can be used in industrial areas. Methods: Corrosion efficiency, corrosion behavior and corrosion mechanism of Arum dioscoridis leaf extract on mild steel (MS) are illuminated in 1 M HCl by Tafel curves, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), zero charge potential, structural and surface morphological analysis and density functional theory (DFT). Significant findings: The extract function as mixed-type corrosion inhibitor with predominantly cathodic action. Inhibition efficiency was reached the value of 97 %. Polarization resistance is measured as 761 Omega cm2 at 1000 ppm of AD. The high inhibition efficiency was attributed to phytochemicals in the AD extract. A high activation energy (70.34 kJ/mol) for inhibited solution than that of in blank solution (49.66 kJ/mol). Both physisorption and chemisorption are responsible for formation of a protective layer on MS surface to inhibit the electrochemical reactions. Optimized molecular structures in phytochemicals confirmed the inhibitive properties via DFT.

Background: Potentilla fulgens, , a highly valued indigenous medicinal herb grown in high altitudes of the Himalayan region with anticancer, hypoglycaemic, antibacterial, anti-inflammatory, and antiulcerogenic properties, are used in traditional systems of medicine. This study was aimed to investigate the effect of P. fulgens root extract, as one of the natural alternatives to chemotherapeutic drugs used in cancer treatment, on proliferation, apoptosis, and autophagy of human non-small cell lung cancer cell line (A549), human ovarian cancer cell line (SKOV-3), and healthy human umbilical vein endothelial cell line (HUVEC). Methods: Anti-proliferative effect was assessed by MTT assay. The expression of autophagy and apoptosis-related proteins was evaluated by western blotting. Total oxidant status (TOS) and total antioxidant capacity (TAC) test were determined using standard kit methods. Results: Our results showed that the extract inhibited proliferation of HUVEC, A549, and SKOV-3 cells in a dose- dependent manner. MTT assay analysis revealed that the extract significantly (P<0.05) P <0.05) induced mortality in HUVEC, A549, and SKOV-3 cells. Western blot results revealed increased expression of NF-kappa B after the extract treatment but led to the down-regulation in Beclin-1, Bax, extracellular-signal-related kinase 1 and 2, Sequestosome-1, and cleaved Casp-3 levels. Treatment groups showed an increase in TOS and TAC values in A549 and SKOV-3 cell lines, while HUVEC cell line showed an increase in TAC and a decrease in TOS values, compared to the control group. Conclusions: Our findings indicated that P. fulgens root extract inhibited the proliferation of healthy cells and cancer cells through cell cycle arrest, representing its limited application as therapeutic agent in cancer treatment.

Vocational School of Health Services / Sağlık Hizmetleri Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Purpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (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.

Objective: 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.

As global agricultural demands continue to rise amidst increasing environmental stressors, enhancing plant resilience has become a critical necessity. Heavy metals (HMs), especially arsenic (As), severely impact crop productivity and quality, threatening global food security and human health. Arsenic toxicity disrupts normal physiological, biochemical and molecular processes in food crops due to its eco-toxicological effects. Nano-enabled biochar (Nano-BC) has emerged as a promising soil amendment capable of mitigating As-induced oxidative stress in horticultural crops by modulating stress responses, enhancing detoxification pathways and improving plant resilience. This review comprehensively examines the interactions of Nano-BC with soil matrices and microbial communities, highlighting its dual role in influencing soil health and plant growth. While Nano-BC improves soil structure, increases nutrient retention and supports beneficial microbial populations, its potential long-term ecological impacts and interactions with native microbial communities require further evaluation. Furthermore, we discuss the mechanisms by which Nano-BC modulates As bioavailability, phyto-toxicity and detoxification pathways in horticultural crops. Advances in Nano-BC applications have demonstrated its potential in producing "pollution-safe" crops, yet challenges remain regarding its environmental fate and persistence. Future research should focus on optimizing Nano-BC formulations to enhance its efficiency while minimizing unintended ecological consequences. By integrating Nano-BC into sustainable agricultural practices, we can move closer to achieving food security, mitigating HM stress in crops and aligning with global sustainable development goals (SDGs).

The efficiency and potential of green Rumex acetosella extract (RAE) RAE ) on the inhibition of the mild steel (MS) corrosion were investigated in the acidic environment. The high inhibitive capability of RAE on the mild steel was studied by electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) techniques. In addition, potentiodynamic (PD) polarization measurements were carried out to examine corrosion mechanism. The achieved electrochemical tests showed that RAE has a significant inhibition effect on mild steel corrosion. The results of surface analysis recorded by scanning electron microscopy (SEM), and atomic force microscopy (AFM) depicted that RAE provide strong protective layer on the steel surface via adsorptive groups. The inhibition efficiency was calculated as 99.7 %, and 99.6 % from LPR and EIS after 120 h exposure time. Adsorption free energy ( Delta G oads ) value is found as-29.79 kJ mol-1,- 1 , indicating that both physical and chemical adsorptions occur. Furthermore, the obtained experimental findings were supported with quantum chemical calculation results.

Metal nanoparticles are very valuable products due to their wide range of uses. 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.

Some industrial applications such as oil well acidification, steel pickling, acid descaling and chemical cleaning are carried out in acid environments. During these processes, corrosion of steel is inevitable. This study focuses on the extraction and corrosion behavior of Polygonum aviculare L. (PA) leaf extract as a novel corrosion inhibitor and developing a highly effective, eco-system friendly corrosion inhibitor for mild steel (MS). Corrosion behavior and mechanism of PA leaf extract are revealed on MS in 1 M HCl by Tafel curves, electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), zero charge potential, structural and surface analysis and density functional theory (DFT). According to findings, FT-IR results reflected some groups such as -OH, -CH, C-O, C=C, C=O and ether. LC-ESI-MS/MS detected the phenolic acids, flavonoids, phytosteroids and phenolic aldehyde characterized as phytochemicals. PDP, EIS and LPR underscored that corrosion current densities decreased to 0.06 mA cm-2, polarization resistances increased to 457 ohm cm2 and inhibition efficiency increased to 96 %. In the comparison of the inhibition efficiency with the literature, PA extract exhibited outstanding corrosion inhibition efficiency (96 %). The adsorption property of PA extract matched the Langmuir process. PA extract showed an adsorption layer even at high temperatures. This behavior is confirmed by a high value of Ea (53.04 kJ/mol). Almost smooth, more compact, and homogenous surfaces were revealed by SEM. Molecules of phytochemicals in PA extract showed both physical and chemical adsorption. These interactions reduced the MS deterioration from corrosion. According to quantum chemical calculation, chlorogenic acid had the highest corrosion inhibitor efficiency among the other phytochemicals. The findings obtained from this study have the potential to contribute to the advancement of sustainable corrosion protection strategies and can provide basic guidance for industrial applications.

The use of nanoparticles (NPs) as an amendment to reduce salt toxicity has gained much attention. Keeping in mind, this research work was done to evaluate the effect of zinc oxide NPs (ZnO-NPs) to mitigate the salt stress in rice (Oryza sativa) plant. Rice plants were subjected to salt stress (150 mM of NaCl) at 15 days of sowing through the soil. ZnO-NPs were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) and were applied foliar at concentration of 100 mg/L for five consecutive days (26-30 DAS). The results confirmed the salt toxicity and reduced shoot length (27 %), root fresh weight (31 %), SPAD chlorophyll (29 %), net photosynthetic rate (24 %), and nitrogen (N), phosphorus (P), potassium (K) and zinc (Zn) uptake by 9 %, 11 %, 13 % and 17 % respectively, while salinity increased the activity of antioxidant enzymes, proline, hydrogen peroxide (H2O2), and malondialdehyde (MDA) content in rice plants. However, in plants grown under salt stress, foliar application of ZnONPs significantly improved growth, photosynthesis, nutrient uptake and antioxidant enzymes activity. Beside, ZnO-NPs reduced salinity-induced oxidative stress by lowering H2O2 and MDA content. Therefore, our research showed that ZnO-NPs is useful and efficient in encouraging growth and lessening salinity stress in rice plants.
