during an 11 days mission in february 2000 the shuttle radar topography mission (srtm) collected data over 80% of the earth's land surface, for all areas between 60 degrees n and 56 degrees s latitude. since srtm data became available, many studies utilized them for application in topography and morphometric landscape analysis. exploiting srtm data for recognition and extraction of topographic ...

Postmenopausal women taking oestradiol 17-beta 2 mg daily were randomized to receive either 25 or 50 microg gestodene from day 17 to 28 of the cycle in a double-blind study. Placental protein P14 (PP14) and CA 125 concentrations in uterine flushing, endometrial morphology and irregular bleeding after 12 cycles of study were observed. Eleven and 12 women in the 25 and 50 microg groups respective...

The origins of the main cultivar groups Vitis vinifera, their relationships with wild grapevine populations, and use other Vitaceae are relevant issues for improvement conservation diversity. Morphometric studies, domestication indices, multivariate analyses, Bayesian hypothesis testing have been used. Eight different seed types identified in 24 samples analyzed from materials Upper Euphrates s...

We analyzed the relationship between motor nerve conduction velocity (MCV) and morphological changes in regenerating nerve fibers at different times after sciatic nerve transection to identify reliable indices of functional recovery. Thirty rats were divided into five equal groups, one control group and four groups subjected to sciatic nerve transection and immediate suturing, followed by regen...

Cigarette smoking produces pulmonary hypertension (PHT) through unknown mechanisms. In animal models acute smoke exposure induces cell proliferation in the small arteries adjacent to the alveolar ducts, and chronic exposure results in muscularisation of these vessels, with changes related to the development of PHT. Studies indicate that serine-elastase inhibitors can prevent experimental monocr...

Various indices of capillary supply to the rat heart were studied in neonatal rats injected for 2 or 4 weeks with protamine sulfate in saline (subcutaneously, 60 mg/kg body weight, 2 times/day). Cardiac capillarization was evaluated not only by traditional indices for the capillary supply, such as mean capillary density and myocyte-to-capillary ratio, but also by a more advanced morphometric me...

Rodents of the family Octodontidae, endemic to South America, represent a group with low taxonomic richness (six genera and 14 species) but have great ecomorphological diversity epigean, semi-fossorial, fossorial, subterranean forms. We analyzed morphometric variation in humerus ulna, possible relationship substrate preference use, presence phylogenetic signal forelimbs traits (five biomechanic...

In this study, all the hairs and their follicles characteristics of Iranian Bakhtiari sheep were investigated. A total of 48 healthy Bakhtiari sheep (aged 5-8 months) were selected and categorized on the basis of sex (24 females and 24 males). Samples were taken as small pieces from different regions of the skin, fixed and stained with haematoxylin and eosin. The following indices in each piece...

European perch undergoes several ontogenetic dietary shifts during its lifetime. The present study focused on the variability in otolith shape caused by changes this species. A total of 172 specimens (7.5 to 27.5 cm TL) were caught local fishermen Lake Ladik from April November 2019. Shape indices (SIs) and elliptic Fourier coefficients (EFCs) calculated for each otolith. To detect shape, SIs E...

OBJECTIVE To develop an interpretation procedure which estimates simulation parameters (tumour cell motility, tumour cell adhesion, autocrine and paracrine growth control, stroma destruction) of simulated patterns solely based on morphometric features of the morphologic pattern. METHODS A cellular automaton computer simulation program was developed which produces morphologic patterns by growt...
