    Evaluation of female athlete triad and gynecological complaints in young Turkish female athletes
    (I R O G Canada, Inc, 2016) Hasdemir, P. Solmaz; Oral, O.; Calik, E.; Ulusoy, M.; Varol, R.; Ozcakir, H. Tayfun
    Purpose: Female athlete triad (FAT) is a serious healthcare concern in the young female population. The aim of this study was to determine the prevalence and clinical characteristics of FAT and its relationship with gynecologic complaints of young Turkish female athletes. Materials and Methods: This was a cross-sectional survey and included 87 female athletes involved in a variety of sports as a case group and 85 sedentary female university students from Ege and Celal Bayar Universities. All subjects completed a questionnaire consisting of 32 separate questions assessing eating behavior, menstrual status, gynecologic and systemic complaints, psychological problems, and sexual history. SPSS 21.0 was used for statistical analysis. Results: This survey involved 172 females in between to 30 years of age. The age of menarche was found to be significantly lower in the sedentary group (p = 0.00). Late menstruation and oligo-amenorrhea were notable complaints among the athletes, and body mass index (BMI) was found to be statistically lower in the athletic group (p = 0.00). Cold hands and hair loss were seen more often in the sedentary group compared to the athletic group (p < 0.05). According to a logistic regression analysis, independent variables (BMI, menstrual status, and bone fractures) were found to be statistically insignificant (p > 0.05). Conclusions: Excessive sports activity can be hazardous in young female population. Lower BMI might be related to menstrual irregularity. Young female population should be informed about this relationship, especially athletes who are particularly at risk. Certain precautions should be taken into consideration in this population in order to get benefits of sports activity.

    Molecular typing of Candida albicans strains isolated from denture wearers by repetitive sequence-based PCR
    (Springer, 2011) Abaci, O.; Haliki-Uztan, A.; Ozturk, B.; Toksavul, S.; Ulusoy, M.; Boyacioglu, H.
    Long-term use of prosthesis is the most important risk factor for the colonization of Candida species on the mucosal surfaces, which can lead to the development of denture-related stomatitis (DRS). Some individuals wearing prosthesis develop DRS and others do not. C. albicans strains isolated from both groups were genotypically compared. The purpose of this study was to determine whether the strain causing prosthesis stomatitis was different from the other strains genotypically. The study included 90 individuals wearing different prostheses and 20 control individuals with natural teeth. In the study 109 C. albicans strains were used which were isolated from the saliva samples and the mucosal surfaces of the tongues and palates of 51 individuals and then defined phenotypically. Phenotypic diagnosis of the isolates was genotypically verified by using species-specific PCR. For molecular typing, repetitive extragenic palindromic sequence polymerase chain reaction (REP-PCR) was employed. The results of the study revealed that REP-PCR had the capability to separate 109 C. albicans strains and six reference strains into 44 genotypes. Whereas C. albicans strains showed heterogenic distribution, C. albicans strains isolated from the individuals suffering from prosthesis stomatitis showed no specific genotypes. REP-PCR is a simple, fast and low-cost method and helped work on a great number of samples.

    Thermal studies of Co(II), Ni(II) and Cu(II) complexes of N,N'-bis(3,5-Di-t-butylsalicylidene)ethylenediamine
    (Springer, 2009) Dogan, F.; Ulusoy, M.; Ozturk, O.-F.; Kaya, I.; Salih, B.
    The thermal decomposition kinetics of sterically hindered salen type ligand (L) and its metal complexes [M=Co(II), Ni(II), Cu(II)] were investigated by thermogravimetric analysis. A direct insertion probe-mass spectrometer (DIP-MS) was used for the characterization of metal complexes of L and all fragmentations and stable ions were characterized. The thermogravimetry and differential thermogravimetry (TG-DTG) plots of salen type salicylaldimine ligand and complexes showed a single step. The kinetic analysis of thermogravimetric data was performed by using the invariant kinetic parameter method (IKP). The values of the invariant activation energy, E (inv) and the invariant pre-exponential factor, A (inv), were calculated by using Coats-Redfern (CR) method. The thermal stabilities and activation energies of metal complexes of sterically hindered salen type ligand (L) were found as Co(II)> Cu(II)> Ni(II)> L and E (Cu)> E (Ni)> E (Co)> L. Also, the probabilities of decomposition functions were investigated. The diffusion functions (D (n)) are most probable for the thermal decomposition of all complexes.
