Recently, there has been a great demand for boron-containing compounds (BCCs) with unique biological properties. The demand for the use of these compounds not alone but as additives in composite materials is increasing day by day. In this study, the effect of adding B2O3 compound to the blend of PLA and PEG polymers, which is an important biocompatible shape memory polymer, was investigated. In order to examine the effect of increasing B2O3 additive on the thermal properties of PLA-PEG blend, it was determined by using a Differential Scanning Calorimetry (DSC) and thermogravimetric analyzer (TGA), and it was seen that while the melting temperature of PEG decreased, the melting temperature of PLA increased. In addition, when the thermal stability of the composites was examined, increasing of thermal stability was observed with the addition of B2O3 and a three-step degradation occurred. It was determined that the B2O3/PLA-PEG composite was homogeneous by taking X-ray measurements and SEM measurements. The antimicrobial property of the PLA-PEG blend improved with the increasing B2O3 contribution were observed from the antimicrobial activity measurements of the composite against 4 different bacteria. However, it was determined that the PLA-PEG blend preserved its shape memory effect with increasing diboron trioxide contribution.

İncele - MakaleAçık Erişim2020Reviewing Phlomis rigida Labill From Turkey as a Antimicrobial Efficacy
Sönmez, Pınar Erecevit; Kirbağ, Sevda; Çakilcioğlu, Uğur
This work researched the inhibitory properties of the extract of Phlomis rigida Labill plant including chloroform on gram-negative and positive bacteria, yeasts and dermatophyta; the related plant is used for therapeutic purpose in public. For the disk diffusion method, this extract is effective on Pseudomonas aeruginosa that is one of the negative bacterias by 11.33 ± 0.57 mm inhibition areas. Regarding other bacterias, the effect of the related extract is so low in avoiding the improvement of Escherichia coli, Staphylococcus aureus and Bacillus megaterium by 8.33 ± 0.57 mm inhibition area. It has highly effective on Trichopyton sp. and Candida albicans that are from dermatophytes fungis and yeast by 16.33 ± 0.57 mm inhibition area. About yeast and dermatophytes fungi it has a remarkable impact on Candida glabrata (14.33 ± 0.57 mm inhibition area), Epidermophyton sp. (12.33 ± 0.57 mm inhibition area). Antimicrobial activity of this natural extract against all the microorganisms that were tested by MIC method by concentrations vary by 100 uL and 6.25 uL. Acording to this; the results showed good inhibitory effect with 6.25 μL for C. albicans, Trichophyton sp. with 12.25 μL for C. glabrata. In the other hand it is effective with 25 μL for P. aeruginosa, Epidermophyton sp. with 50 μL for E. coli, S. aureus, B. megaterium. Being used plants for medical purposes as from since the early ages show that these plants can be used as alternatives of available antibiotics; including important medical components is the other reason for being an alternative at the same time. Concerning results, P. rigida can be utilized as a therapeutic drug for the healing of infections caused by microorganisms. In this study, we believe that the P. rigida is important in the search for new antibiotics and will contribute to the literature and the world of drug as it affects different types of microorganisms at the lowest level for the first time.

Sönmez, Pınar Erecevi t; Kuzgun, Nermin Karaton; Kirbağ, Sevda
Ginger (Zingiber officinale) essential oil is considered safe. In this study, ginger (Zingiber officinale) essential oil was used to extend storage life of common carp (Cyprinus carpio) and detect its protective effects. The following tests were performed to assess the shelf life of carp (C:control) treated with ginger essential oil (G). The microbiota growth of the carp, sensory properties, pH, TVB TBA values, the shelf life of the carp changed positively by adding ginger oil in different concentrations to the carp (C1, C2, C3: 0.1%, 0.25%, 0.5%ginger essential oil was added to carp samples). On the other hand; ginger essential oil has a positive effect on TVB-N and TBA values of carp fillets. With reference to the results of microbiota growth, carp sample (C: control) showed the highest value (P < 0.05) on the 6th storage day. The results show the importance of the use of Zingiber officinale essential oil to prevent food spoilage.

Erecevit Sönmez, Pınar; Kirbağ, Sevda; İnci, Şule
Dodder is a plant used for the hepatitis treatment in new born infants in and around Mardin. The aim of this research to determine the antifungal and antibacterial effects of traditionally used dooder is known as a regional folk remedy. Thus and so, the efficacy of the drug has been demonstrated by the inclusion of natural therapeutic antimicrobial agents such as anti-inflammatory and wound healing, including infectious diseases. The antimicrobial effects of these plant was analyzed against bacteria, yeast and dermatopyta fungi by the agar disc diffusion method. The nominal concentration of the plant to prevent from the development of microorganisms was detected with the broth microdulitions method. It was determined that it had sensitive and moderately sensitive antimicrobial effect against all of microrganisms (13-19.66 mm/inhibition zone), growth of tested microrganisms were inhibited at 50-6.25 µL.It is though that this natural herbal resource can light the way for treatment of several diseases and direct the next studies because of having the potential for being used as a new antimicrobial agent.
