inhibitor development is a lifelong challenge for patients with bleeding disorders who received replacement therapy. most commonly, inhibitor formation was observed in hemophilia a patients but patients with rare bleeding disorders (rbd) especially patients with deficiency of factor xiii (fxiii) and factor v (fv) can develop an inhibitor against exogenous factors. several factors considered as ...

Invasive Alien Plants occur in numbers differing by orders of magnitude at subsequent invasion stages. Effective sampling and quantifying niches of rare invasive plants are quite problematic. The aim of this paper is an estimation of the influence of invasive plants frequency on the explanation of their local abundance. We attempted to achieve it through: (1) assessment of occurrence of self-re...

The paper presents data on the occurrence and secondary spreading of rare and threatened vascular plant species in railway habitats of Slovakia. We recorded 17 threatened vascular plant species and other 9 species that we considered to be rare in Slovakia. They grew at railway stations, mainly directly in the rail yard and also at the platforms or other similar facilities. Records of further 39...

The analysis of genetic structure and variability of isolated species is of critical importance in evaluating whether stochastic or human-caused factors are affecting rare species. Low genetic diversity compromises the ability of populations to evolve and reduces their chances of survival under environmental changes. Petunia secreta, a rare and endemic species, is an annual and heliophilous her...

The meiotic chromosome counts are reported in 10 species of the genus Cousinia including: C. adenostegia, C. antonowii, C. chaetocephala, C. dasylepis, C. eriobasis, C. freynii, C. prasina, C. rechingerorum, C. termei and C. trachyphyllaria from Iran. Specimens have been collected from different parts of Iran out of which, eight species are considered to be new and two provide confirmation of t...

Developing supernumerary limbs is a rare congenital condition that only a few cases have been documented. Depending on the cause and developmental conditions, they may be single, multiple or complicated, and occur as a syndrome or associated with other anomalies. Polymelia is defined as the presence of extra limb(s) which have been reported in human, mouse, chicken, calf and lamb. It seems that...

The chromosome number and karyotype formula of interesting five genera six species Araceae from Thailand were studied, including Lasia spinosa —uncommon local Thai vegetable (2n=26, L6sm+L2st+Mm14+M4sm), Pistia stratiotes—common aquatic plant (2n=28, Lm10+Mm18), Pycnosphata palmata—rare endemic to Laos Lm12+L4sm+M6m+M2sm+M2st), Scittomaglottis calyptrata—rare in Lm6+L2sm+Mm6+Msm12), Typhonium g...

the analysis of net catches made in absheron gulfs of the caspian sea during 2011-2012 is provided. the ichthyofauna of absheron gulfs, including 26 species found in the north gulf, and 33 species and subspecies found in the south gulf was studied for the first time. a taxonomical and ecological diversity of the fish fauna of north and south absheron gulfs is characterized. the peculiarities of...
