Abstract Species distribution modeling was used to determine factors among the large predictor candidate data set that affect of Muscari latifolium , an endemic bulbous plant species Turkey, quantify relative importance each factor and make a potential spatial map M. . Models were built using Boosted Regression Trees method based on 35 presence 70 absence records obtained through field sampling in Gönen Dam watershed area Kazdağı Mountains West Anatolia. Large variables monthly seasonal...
To evaluate the efficacy of myo-inositol (MI) pretreatment in OHSS. In this experimental OHSS rat model, 42 immature Wistar albino female rats were divided into 6 groups: (1) control group, (2) ovarian stimulation (3) (4) + Metformin (5) MI (6) group. was established after treatment with metformin and for 14 days, meanwhile also continued. All animals killed 48 h hCG administration compared terms vascular permeability, weight diameter, VEGF, COX-2 PEDF expression (immunohistochemistry),...
Lichens have important ecological functions in black pine forests, such as nitrogen fixation and nutrient cycling. Understanding lichen diversity could provide a better understanding of ecosystems. The aim this study was to identify the factors affecting composition communities their specific Mediterranean forests. Research conducted 48 sampling plots. For analysis, presence–absence frequency data species were used. stand level four community tables created. We used bioclimate, topography,...
Ethanolic (EEAA) and sesquiterpene lactone (SEAA) extracts of the aerial parts Anthemis aciphylla var. Boiss. (Asteraceae) were evaluated for anti-inflammatory activity on carrageenin-induced paw edema (acute model) cotton pellet-induced granuloma (chronic in rats. In edema, EEAA SEAA at intraperitoneal doses 50, 100, 200 mg/kg dose-dependently inhibited edema. granuloma, oral administration dosages was also found to significantly inhibit tissue formation.
Objective: The aim of this study is to investigate the effects resveratrol in a rat model ovarian hyperstimulation syndrome (OHSS) and compare with cabergoline.Design: Randomized controlled, animal study.Animal(s): Female Wistar rats.Material methods: A OHSS was used cabergoline administration for preventing OHSS. Body weight, ovary diameter, vascular permeability (VP), endothelial growth factor (VEGF), cyclooxygenase-2 (COX-2) expression (immunohistochemistry), serum estradiol (E2) levels...
Intellectual capital is among the new, advanced management notions developed to overcome inadequacy of previous administrations, adapt new situations and forge ahead competition. means information, experience skills that offer advantage in competition reveal values existing within structure an enterprise. These also exist relationship between enterprise environment with employees. Although some research studies on intellectual (IC) have been conducted, date no has carried out effects IC...
The spatial interpolation and multi-criteria decision analysis (MCDA) capabilities of geographic information systems have the potential to create new approaches forest management. In this study heterogeneously structured stand maps, use regularized spline with tension (RST) method ELECTRE TRI MCDA was investigated. For each species diameter class, one map predicted volume per ha produced RST method. used data from a total 1050 circular sample plots. By repeating same process for eight...
Understanding the distribution of individual species and factors affecting their is a key issue in biogeography, ecology conservation. This study was carried out to determine bioclimatic two pedunculate oak subspecies ( Quercus robur L. subsp. Q. pedunculiflora (K.Koch) Menitsky ) Turkey tolerances these factors. Mean Temperature Coldest Quarter (Bio 11), Month 6), Annual Range 7), Seasonality (Bio), Precipitation 15), Isothermality 3), (Bio1) are highly correlated variables that effect...
In disciplines such as agriculture, forestry and horticulture, it is customary to make use of various hardiness zone maps intended for the selection plant species be cultivated within specific regions. The most widely used these USDA Plant Hardiness Zone (PHZ) map. Recently, American Horticultural Society also created Heat (AHZ) Map. PHZ AHZ have not yet been produced Turkey. To overcome deficiencies compare distribution major forest tree over zones, data from 260 meteorological stations...
Il est proposé une nouvelle interprétation de données Rb-Sr portant sur le socle ancien du massif Bitlis dans Sud-Est la Turquie. La série métamorphique à amphibolites, paragneiss et gneiss blancs a été métamorphisée faciès amphibo-lite almandin, limite Protérozoique -Cambrien. Son âge réel donc supérieur. Les ortholeptynites les granites sont très albitisés. L'âge cette recristallisation se situe entre 110 70 MA, l'imprécision étant due qualité des mesures au caractère incomplet...
Abstract The River Buyukmelen is located in the province of Duzce northwest Turkey and its water basin approximately 470 km 2 . Aksu, Kucukmelen Ugursuyu streams flow into Buyukmelen. It flows Black Sea with an output 44 m 3 s −1 geological succession comprises limestone dolomitic Yılanlı formation, sandstone, clayey marls Akveren clastics volcano‐clastics Caycuma cover units comprised river alluvium, lacutrine sediments beach sands. expected to be a source that can supply drinking needs...
Better understanding of the competitive interaction at early development stages stand is crucial to help schedule silvicultural treatments for young stands and better management future stands. We used scale-dependent analysis improve our sapling dynamics in pure Taurus cedar (Cedrus libani A. Rich.) Southern Turkey. Using data from nine plots established western Mountains, diameter, height, crown radii saplings were compared, spatial point pattern analyses performed. found significant...
The purpose of the study is to find effects different growing site conditions on trees with vessel features in woods Quercus ilex L. regions through Turkey, and evaluate results respect forestry. A total 102 wood samples were collected from sampling plots (as 20 m × 10 plots) 9 distribution areas Turkey. Environmental, climate stand data obtained for each plot. Standard anatomical studies performed. show that, while element lengths are almost stable all regions, most changeable feature...
It is known that hypoxic pulmonary vasoconstriction increases as a result of intermittent regional challenges. The aim this study was to compare the effects sevoflurane and propofol on oxygenation shunt fraction during one-lung ventilation in novel model preconditioning before ventilation.Sixteen Wistar-albino rats were anesthetized intra-peritoneally venous arterial cannulations tracheotomized. animals randomly allocated receive either 2% or 10mg/kg/h infusion ventilated with 100% oxygen at...
Türkiye’de üç herdem yeşil meşe türü [pırnal meşesi (Quercus ilex L.), kermes coccifera L.) ve boz pırnal aucheri Jaub. &amp; Spach)] doğal yetişmektedir. Bu türlerin adları bilimsel kaynaklar geleneksel kullanımda yer önemli farklılıklar içermektedir. Makalenin amacı, Türkiye’deki meşelerin halk arasındaki adlarının bir değerlendirmesini yapmak bu Türkçe kullanımına yönelik ortak dil geliştirme adına öneriler sunmaktır. kapsamda yapılan değerlendirmelerde, Quercus için “çakpelit kaba...
