Item Antimicrobial activity of two wild mushrooms Clitocybe alexandri (Gill.) Konr. and Rhizopogon roseolus (Cords) T.M.!Fries collected from TurkeySolak, MH; Kalmis, E; Saglam, H; Kalyoncu, FTwo edible wild mushrooms, namely Clitocybe alexandri (Gill.) Konr. (Tricholomataceae) and Rhizopogon roseolus (Cords) T.M. Fries (Rhizopogonaceae), collected from the southwest of Turkey, were tested for their antimicrobial activity by using the disc diffusion method. The ethanol, methanol, diethyl ether, water, ethylacetate and n-hexane extracts from the fruit bodies of mushrooms were assayed against 13 microorganisms. In comparison with the test antibiotics penicillin, novobiocin, nalidixic acid and ampicillin, the methanol extract obtained from the two mushrooms presented significant activity against E. coli, Bacillus subtilis and Enterobacter aerogenes. On the other hand, the ethylacetate extract from C. alexandri was found to be active against Candida albicans and Saccharomyces cerevisiae, whereas the ethanol extract of Rhizopogon roseolus was active against Saccharomyces cerevisiae. This research has shown that various extracts obtained from two macrofungi could be used in vitro to inhibit the growth of some important bacteria and fungi.

For determination of antimicrobial activities of these mushrooms, ethanol extracts were examined with 11 test microorganisms by the agar well diffusion method. P. ostreatus and M. giganteus were the most active species against both bacteria and yeast. Antioxidant properties of ethanol extracts were studied by the 1,1-diphenyl-2-picrylhydrazyl free radical scavenging method. Among the mushroom extracts, M. elata showed the most potent radical scavenging activity. This research has shown that these 10 wild macrofungi have potential as natural antioxidants and antibiotics.Item Antimicrobial activity of common madder (Rubia tinctorum L.)Kalyoncu, F; Cetin, B; Saglam, HIn this study, ethanol, methanol, ethyl acetate and water extracts of Rubia tinctorum L. (Rubiaceae) were tested for antimicrobial activity by the disc diffusion method. From the present study it was found that Rubia tinctorum L. revealed antimicrobial activity against some Gram (+) and Gram (-) bacteria, yeasts, filamentous fungi and actinomycetes.

In addition to the in vitro activities of the ethanol, acidified and alkaloid extracts and furoquinoline alkaloids skimmianine and gamma-fagarine, in vivo antileishmanial activitiy of the acidified extract of Haplophyllum myrtifolium Boiss. (Rutaceae) were investigated against Leishmania tropica (L. tropica), a causative agent of cutaneous leishmaniasis. All the extracts and pure compounds showed in vitro inhibitory activity against the promastigotes of. L. tropica. The in vitro 50% inhibitory concentrations of gamma-fagarine, acidified extract, ethanol extract, skimmianine and alkaloid extract against promastigotes were determined as 8.7, 9.4, 10.9, 25.7 and 25.8 mu g/ml respectively. In vivo results of Haplophyllum myrtifolium acidified extract showed that this plant has a limited effect on decreasing the lesion size of experimental mice infected with Leishmania tropica. To the best of our knowledge, this is the first time both the in vitro and in vivo antileishmanial activity of Haplophyllum mrytifolium have been reported in the same research.Item Anthropometric findings from birth to adulthood and their relation with karyotpye distribution in Turkish girls with Turner syndromeSari, E; Bereket, A; Yesilkaya, E; Bas, F; Bundak, R; Aydin, BK; Darcan, S; Dündar, B; Büyükinan, M; Kara, C; Adal, E; Akinci, A; Atabek, ME; Demirel, F; Çelik, N; Öakan, B; Özhan, B; Orbak, Z; Ersoy, B; Dogan, M; Atas, A; Turan, S; Göksen, D; Tarim, Ö; Yüksel, B; Ercan, O; Hatun, S; Simsek, E; Ökten, A; Abaci, A; Döneray, H; Özbek, MN; Keskin, M; Önal, H; Akyürek, N; Bulan, K; Tepe, D; Emeksiz, HC; Demir, K; Kizilay, D; Topaloglu, AK; Eren, E; Özen, S; Demirbilek, H; Abali, S; Akin, L; Eklioglu, BS; Kaba, S; Anik, A; Bas, S; Unuvar, T; Saglam, H; Bolu, S; Özgen, T; Dogan, D; Çakir, ED; Sen, Y; Andiran, N; Çizmecioglu, F; Evliyaoglu, O; Karagüzel, G; Pirgon, Ö; Çatli, G; Can, HD; Gürbüz, F; Binay, Ç; Bas, VN; Fidanci, K; Gül, D; Polat, A; Acikel, C; Cinaz, P; Darendeliler, FTo evaluate the anthropometric features of girls with Turner syndrome (TS) at birth and presentation and the effect of karyotype on these parameters. Data were collected from 842 patients with TS from 35 different centers, who were followed-up between 1984 and 2014 and whose diagnosis age ranged from birth to 18 years. Of the 842 patients, 122 girls who received growth hormone, estrogen or oxandrolone were excluded, and 720 girls were included in the study. In this cohort, the frequency of small for gestational age (SGA) birth was 33%. The frequency of SGA birth was 4.2% (2/48) in preterm and 36% (174/483) in term neonates (P<0.001). The mean birth length was 1.3cm shorter and mean birth weight was 0.36kg lower than that of the normal population. The mean age at diagnosis was 10.1 +/- 4.4 years. Mean height, weight and body mass index standard deviation scores at presentation were -3.1 +/- 1.7, -1.4 +/- 1.5, and 0.4 +/- 1.7, respectively. Patients with isochromosome Xq were significantly heavier than those with other karyotype groups (P=0.007). Age at presentation was negatively correlated and mid-parental height was positively correlated with height at presentation. Mid-parental height and age at presentation were the only parameters that were associated with height of children with TS. The frequency of SGA birth was found higher in preterm than term neonates but the mechanism could not be clarified. We found no effect of karyotype on height of girls with TS, whereas weight was greater in 46,X,i(Xq) and 45,X/46,X,i(Xq) karyotype groups.

Many countries have population-specific growth charts for TS. Considering national and ethnic differences, we undertook this multicenter collaborative study to construct growth charts and reference values for height, weight and body mass index (BMI) from 3 years of age to adulthood for spontaneous growth of Turkish girls with TS. Methods: Cross-sectional height and weight data of 842 patients with TS, younger than 18 years of age and before starting any therapy, were evaluated. Results: The data were processed to calculate the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for defined ages and to construct growth curves for height-for-age, weight-for-age and BMI-for-age of girls with TS. The growth pattern of TS girls in this series resembled the growth pattern of TS girls in other reports, but there were differences in height between our series and the others. Conclusion: This study provides disease-specific growth charts for Turkish girls with TS. These disease-specific national growth charts will serve to improve the evaluation of growth and its management with growth-promoting therapeutic agents in TS patients.Item Turner Syndrome and Associated Problems in Turkish Children: A Multicenter StudyYesilkaya, E; Bereket, A; Darendeliler, F; Bas, F; Poyrazoglu, S; Aydin, BK; Darcan, S; Dündar, B; Büyükinan, M; Kara, C; Sari, E; Adal, E; Akinci, A; Atabek, ME; Demirel, F; Çelik, N; Özkan, B; Özhan, B; Orbak, Z; Ersoy, B; Dogan, M; Atas, A; Turan, S; Göksen, D; Tarim, Ö; Yüksel, B; Ercan, O; Hatun, S; Simsek, E; ÖOkten, A; Abaci, A; Döneray, H; Özbek, MN; Keskin, M; Önal, H; Akyürek, N; Bulan, K; Tepe, D; Emeksiz, HC; Demir, K; Kizilay, D; Topaloglu, AK; Eren, E; Özen, S; Abali, S; Akin, L; Eklioglu, BS; Kaba, S; Anik, A; Bas, S; Ünüvar, T; Saglam, H; Bolu, S; Özgen, T; Dogan, D; Çakir, ED; Sen, Y; Andiran, N; Çizmecioglu, F; Evliyaoglu, O; Karagüzel, G; Pirgon, Ö; Çatli, G; Can, HD; Gürbüz, F; Binay, C; Bas, VN; Fidanci, K; Polat, A; Gül, D; Açikel, C; Demirbilek, H; Cinaz, P; Bondy, CObjective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014. Results: The most common karyotype was 45, X (50.7%), followed by 45, X/46, XX (10.8%), 46, X, i(Xq) (10.1%) and 45, X/46, X, i(Xq) (9.5%). Mean age at diagnosis was 10.2 +/- 4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45, X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%. Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan.
