Item Incidence of severe glucose-6-phosphate dehydrogenase (G6PD) deficiency in countryside villages of the central city of Manisa, Turkey(TIP ARASTIRMALARI DERNEGI, 2006) Minareci E.; Uzunoǧlu S.; Minareci O.Aim: The primary objective of this study was to determine the incidence of severe G6PD deficiency in selected countryside villages of central city of Manisa in Turkey. Secondarily to inform and protect G6PD deficient people from acute hemolytic crisis and neonatal jaundice by delivery of the updated protective food and drug list prepared in the light of the WHO- G6PD Working Committe reports. Methods: In this study, the incidence of severe G6PD deficiency were screened by Beutler's Fluorescence Spot test among 1604 people living in the contryside villages of central city of Manisa in Turkey. Results: Thirty five out of 1604 tested people were found to have severe G6PD deficiency. The incidence of severe G6PD deficiency were 2.2 % in sampled population. There was a difference for the incidence between male (3.2%) and female (1.14%) as expected due to X-linked heritance. There was no significant differences in the prevalence of severe G6PD deficiency between the countryside villages connected to central city of Manisa. Conclusion: The high incidence of severe G6PD deficiency implies that this inherited metabolite disorder is an important health problem in Manisa region and it is necessary to carry out large-scale screening in the whole population since severe- full G6PD deficiency related health problems are preventable. For this reason it must be included in the pool of genetic screening tests in regional health policy.Item A karyotypic study on Silene, section Siphonomorpha species of Turkey(2008) Yildiz K.; Minareci E.; Çirpici A.; Dadandi M.Y.Karyology of the eight taxa of Silene sect. Siphonomorpha known from Turkey was investigated. Diploid chromosome numbers and the basic chromosome number of the studied taxa were obtained as 2n =24 and x = 12, respectively. A karyotype analysis of the studied taxa was carried out and the chromosome numbers of S. splendens, S. amana and S. phrygia were determined for the first time. The smallest chromosomes were observed in S. fruticosa and the largest in S. italica subsp. italica. Silene splendens showed the highest A 1 index, whereas S. amana had the highest interchromosomal asymmetry coefficient(A 2). The karyologic results of the study and the analysis of chromosomal morphology of each taxon is presented.Item Antimicrobial activity of five endemic Asperula species from Turkey(Brieflands, 2009) Kalyoncu F.; Minareci E.; Minareci O.In this study, methanol and ether extracts of five endemic Asperula species (Rubiaceae) from Turkey (A. antalyensis, A. brevifolia, A. pseudochlorantha, A. purpurea subsp. apiculota and A. serotina), used in the traditional system of medicine, were tested for antimicrobial activity by the agar well diffusion method and the broth dilution method. The most active species were Asperula brevifolia and A. serotina which showed broad-spectrum antimicrobial activity against Gram-positive and Gram-negative bacteria and maximum inhibition was shown by methanol extract of A. antalyensis against Candida albicans as 32 mm. Methanol extracts of Asperula species were among the most active with the MIC values ranging from 7.6 to 14.8 mg/mL.

Cu, Fe, Mn, Zn, Cd, Co, Cr, Ni and Pb content of water and sediment samples were investigated. The values obtained in this study were compared with permitted maximum heavy metal concentrations for irrigation. All metal concentrations found were low ( Cu 0.10, Fe 0.28, Mn 0.19, Zn 1.32, Cd 0.004, Co 0.006, Ni 0.12, Pb 0.22 mg L-1) but chromium (0.12 mg L-1) was at limit concentration at some stations. According to these results, the water is acceptable for irrigation. Furthermore, water sample results were compared with inorganic pollution limit amounts announced by the Water Pollution Control Regulation. It is obvious that the water pollution at Gediz River reached levels threatening public health, because of the high chromium (0.12 mg L-1) and lead (0.22 mg L-1) levels.Item Detergent and phosphate pollution in Gediz River, Turkey(2009) Minareci O.; Öztürk M.; Egemen Ö.; Minareci E.The Gediz River, located in western Turkey, drains a region with a high population density and a strong economic activity. These factors, together with a lack of facilities for appropriate treatment of domestic and industrial sewage, are putting increasing pressure on water resources. The aim of the present study was to identify point sources of detergent pollution and to assess the surface water quality in the Gediz River by monitoring physicochemical variables. Point sources of wastewater, including some with a high pollution load, were detected in the most populated and industrialized areas of Manisa and Muradiye municipalities. These sources contribute to increasing degradation of water quality observed in the river. Concentrations of anionic detergents and phosphate were 0.084 - 5.592 g m-3 and 0.0044 - 0.248 g m -3, respectively. Gediz River is a significant contributor of nutrients to the Aegean Sea. © 2009 Academic Journals.Item Determination of heavy metals in fish, water and sediments of avsar dam lake in Turkey(2009) Öztürk M.; Özözen G.; Minareci O.; Minareci E.In the present study, some heavy metals (Cd, Cr, Cu, Fe, Ni and Pb) were seasonally determined in water, sediment and some tissues of Cyprinus carpio from Avsar Dam Lake, which is an important water source for irrigation and drinking in Turkey. Heavy metal levels in water, sediment and fish samples were analyzed by inductively coupled plasma spectroscopy (ICP/AES). The obtained results showed that the average values of Fe in water samples were higher than the respective reference values for fresh water. Results for levels in water were compared with national and international water quality guidelines, as well as literature data reported for the lakes. The analysis of heavy metals in sediments indicated that among the six heavy metals tested, Fe was maximally accumulated, followed by Ni, Cu, Cr, Pb and Cd. Heavy metal concentrations were found to decrease in sequence of the Cyprinus carpio samples, in the muscle and stomach-intestine as Fe > Cu > Pb> Ni > Cr > Cd; in the gill, heart and liver as Fe > Cu > Ni > Pb > Cr > Cd and in the air sac as Fe > Cu > Ni > Pb > Cd >Cr. In the fish samples, cadmium, chromium, nickel and lead concentrations exceeded the tolerable values provided by international institutions.Item Karyological studies in some species of the genus silene (Caryophyllaceae)(2009) Minareci E.; Yildiz K.; Çirpici A.Summary Karyology of the 6 Silene species from Turkey was investigated. Diploid chromosome numbers and the basic chromosome number of the studied taxa were obtained as 2n=24 and x= 12 respectively. The karyotype analysis of S. viscosa, S. eremítica, S. skorpilii and S. confertiflora were carried out for the first time. Also the chromosome numbers of S. eremítica and S. confertiflora were determined for the first time. The largest chromosomes were observed in S. otites and the smallest ones were observed in S. viscosa. S. otites shows the highest A1 index. S. sforpilii represents the highest interchromosomal asymmetry coefficient (A2). The karyologic results of the study and the analysis of chromosomal morphology of each taxon were shown as tables. ©2009 The Japan Mendel Society.Item A karyotypic study on Silene sect. Sclerocalycinae in Turkey(2009) Yildiz K.; Minareci E.; Çirpici A.The karyology of fifteen taxa of Silene sect. Sclerocalycinae from Turkey has been investigated.

Their morphological features showed very minor difference such as internodes length and the vein thickness of leaf, however, the seed and pollen characteristics clearly appear to have taxonomic value. The clavate-reticulate seed surface suture of A. serotina clearly differs from that lineate-sulcate of A. purpurea subsp. apiculata. Similarly, the pollen perforations and number of spines differ in each taxon. Moreover, the two taxa are geographically isolated from each other. Ecological features are also briefly discussed. The seed and pollen micromorphological properties could be used for intra/interspecific classification of Asperula which is taxonomically critical. © 2010 Academic Journals.Item Asperula pseudochlorantha var. antalyensis comb, et stat. nov. (Rubiaceae)(Finnish Zoological and Botanical Publishing Board, 2010) Minareci E.; Yildiz K.Asperula pseudochlorantha Ehrend, and Asperula antalyensis Ehrend, from Turkey were described in 1958. General characteristics, seed structure and micromorphology, pollen measurements and other pollen characteristics were examined to determine the taxonomie status of these taxa. Morphologically, the two taxa cannot be easily distinguished, and the seeds and pollen grains are similar. The chromosome number is 2n = 22 for both taxa. Based on morphological, palynological and cytological similarities, and the fact that both taxa are found in the same habitats, we propose that A. antalyensis should be recognized as A. pseudochlorantha Ehrend, var. antalyensis (Ehrend.)

Sediment cores were taken from twelve stations. Twenty-eight dinoflagellate cyst types, representing nine genera, were identified. The most common cysts were those of Lingulodinium machaerophorum, Polykrikos kofoidii, Quinquecuspis concreta and Dubridinium caperatum. Potentially toxic species were widely distributed in the study area. This finding is also important to know the seed-bank areas in the Bay of Izmir. © 2010 Academic Journals.Item Karyotype characterization of Turkish taxa of the genus Asperula L. - Section Thlipthisa (Rubiaceae)(2011) Minareci E.; Yildiz K.Karyotype studies were performed in five taxas of Asperula viz., Asperula brevifolia, A. pseudochlorantha var. pseudochlorantha, A. pseudochlorantha var. antalyensis, A. serotina and A. purpurea subsp. apiculata from the section Thlipthisa, and their diploid (2n), and the basic (x) chromosome numbers were determined as 2n=22 and x=11, respectively. Chromosome length varied from 0.80 μm (A. serotina) to 2.40μm (A. brevifolia). Chromosomes are principally metacentric except for A serotina, which has submetacentric chromosomes. A. serotina showed the highest intrachromosomal assymetry coefficient (A 1) index and A. pseudochlorantha var. antalyensis represented the highest interchromosomal asymmetry coefficient (A 2). The chromosome numbers of A. brevifolia, A. serotina and A. purpurea subsp. apiculata were reported for the first time.Item Pollen morphology of sections Siphonomorpha and Lasiostemones of the genus Silene from Turkey; [Türkiye'de yayılış gösteren Silene cinsi Siphonomorpha ve Lasiostemones seksiyonlarının polen morfolojisi](Turkiye Klinikleri, 2011) Yildiz K.; Dadandi M.Y.; Minareci E.; Çirpici A.The pollen morphology of 16 taxa belonging to the sections Siphonomorpha Otth and Lasiostemones Boiss. from the genus Silene L. (Caryophyllaceae) was examined via scanning electron microscopy (SEM). Pollen types among all of the examined taxa were spheroidal, ornamentations were generally microechinate-microperforate (punctate), but perforate in Silene viridiflora L., structures were mostly tectate but were observed to be semitectate only in S. viridiflora, the highest pore numbers were found in S. fruticosa L. and S. viridiflora, the lowest pore numbers were those of S. gigantea L. subsp. rhodopea (Janka) Greuter and S. marschallii C.A.Mey., and interpore distance was greatest in S. gigantea subsp. rhodopea and smallest in S. amana Boiss. The widest perforation was observed in S. Viridiflora, whereas the lowest value was observed in S. olympica Boiss. As a result of these detailed examinations, some Silene species with significant taxonomic problems were reviewed in terms of palynology, and suggestions are provided about their positions. S. viridiflora was determined to be the taxon with the most different pollen morphology according to general characters. According to pore number and perforation, the most advanced taxon was S. Viridiflora, while the most primitive taxa were found to be S. olympica, S. gigantea subsp. rhodopea, and S. olympica. © TÜBİTAK.Item A new record from Turkey: Consoli̇da sami̇a P.H. davi̇s (Ranunculaceae)(2011) Minareci E.; Altan Y.; Aktan T.Consolida samia P.H.Davis (Ranunculaceae) is one of the "Top 50 Plants" of IUCN Species Survival Commission. C. samia, as a new record for the Flora of Turkey is described and illustrated from West Anatolia in this study. The specimens were collected from a gravel-like substrate with the largest pebbles in the Balikesir border of Manisa. The description of the species has also been expanded, following collection of specific plant materials. In this study, the detailed morphological characteristics and palynological properties were determined and compared with the closely related taxon C. hellespontica (Boiss.) Chater. Also, line drawing, photographs and a distribution map of C. samia species of Turkey were presented. Our studies led us to recommend it as CR B1ab (iii,v)+2ab(iii,v), according to the 2001 IUCN categories.Item Chemical compositions and antioxidant activities of five endemic Asperula taxa(2011) Minareci E.; Ergönül B.; Kayalar H.; Kalyoncu F.In this study, the proximate chemical composition, total flavonoid and α-tocopherol amounts and antioxidant activities of five endemic Asperula taxa (Rubiaceae) (A. brevifolia, A. pseudochlorantha var. antalyensis, A. pseudochlorantha var. pseudochlorantha, A. purpurea subsp. apiculata and A. serotina) were determined. Antioxidant properties of methanol extracts were studied by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. Among the all Asperula extracts A. brevifolia showed the most potent radical scavenging activities.Item Distribution of dinoflagellate cysts in recent sediments from Izmir Bay (Aegean Sea, Eastern Mediterranean)(2011) Aydin H.; Matsuoka K.; Minareci E.To determine the species composition, abundance and horizontal distribution of dinoflagellate cysts in recent marine sediments, samples were collected at 13 stations in Izmir Bay, Aegean Sea. At least thirty-six dinoflagellate cyst types were identified, with the assemblages mainly dominated by Lingulodinium machaerophorum, Polykrikos kofoidii, Operculodinium centrocarpum, Gymnodinium cf. nolleri and Quinquecuspis concreta. Total cyst concentrations ranged from 41 to 3292cystsg-1 dry weight sediment. The majority of the cysts occurred in the inner and middle parts of the bay, where higher cyst concentrations were observed. According to the One Way Anova test, the difference between stations was significant statistically (p<0.05). Two of the dinoflagellate cyst species have not been recorded previously as cysts or motile stages in Aegean marine waters; Gymnodinium cf. nolleri and Oblea acanthocysta. Alexandrium minutum and Alexandrium affine type cyst were observed at almost all stations although the cyst type of the Alexandrium catenella/tamarense complex was only found in the outer bay. These findings indicate potential seedbeds for initiation of future blooms and outbreaks of potentially toxic species in Izmir Bay. © 2011 Elsevier B.V.Item A palynological study of the genus Smyrnium (Umbelliferae) from Turkey(2011) Mungan F.; Yildiz K.; Minareci E.; Kiliç M.In this study, the pollen morphology and exine structure of six taxa of the genus Smyrnium L. (Umbelliferae) were investigated using light microscopy and scanning electron microscopy (SEM). Eight micromorphological characters (pollen shape, apocolpium, mesocolpium, polar length, equatorial width, exine thickness, colpus length and colpus width) of pollen grains of Smyrnium have been identified. The palynological observations revealed that pollen grains of all studied taxa of Smyrnium were prolate in shape and posses tricolporate aperture. Tectal surface sculpture was not a good criterion to identify particular taxa from Smyrnium. The pollen of which is characterized by rugulate, the pollen ornamentation was similar in all studied taxa. In addition the taxa could be included in subrectangular pollen type as classified by Cerceau - Larrival. © 2011 Academic Journals.Item Rosularia globulariifolia var. pallidiflora comb. et stat. nov. (Crassulaceae)(2012) Minareci E.; Yildiz K.; Gucel S.; Kuh M.Rosularia globulariifolia (Fenzl) A. Berger and R. pallidiflora (Holmboe) Meikle were originally described as species in Umbilicus DC. in 1842 and 1914, respectively. In the present study, morphological and palynological features were examined in detail to determine the status of these taxa. The general characteristics, seed structure and micromorphology, pollen measurements and pollen characteristics were established. Morphologically, the two taxa cannot easily be distinguished. Pollen grains of both species are tricolporate, subspheroidal and eutectate, ornamentation is psilate and exine structures are similar. Based on morphological and palynological similarities, and the fact that both taxa are found in the same habitats, we propose that R. pallidiflora should be reduced to the rank of variety as Rosularia globulariifolia (Fenzl) A.

Gobius niger were sampled from two stations of the Izmir Bay, and gills and liver were examined histopathologically. The presence of pathological lesions in gills and liver of the fish as possible result of pollutant exposure was evaluated by semiquantitative analyses. The only histopathological changes found were hyperplasia, hypertrophy (12.5%, 18.8%), epithelial degeneration (18.8%, 25%) in gill and fatty livers (12.5%, 25%) of the fishes from both study sites, respectively. The moderate manifestation of pathological lesions in organs of Gobius niger from the presumably Bostanh site may be either the result of substantial protective and detoxification capabilities of this fish species, or from recent measures to reduce water pollution in Izmir Bay such as the installment of wastewater treatment plants.
