Phylogenetic analysis of pandemic influenza A/H1N1 virus
Biologia - Tập 67 - Trang 14-31 - 2012
The principle of the present study was to determine the evolution of pandemic novel influenza A/H1N1 2009 virus (NIV) by phylogenetic, comparative and statistical analyses. The phylogenetic trees of eight genomic segments illustrate that, so far, the sequences of the NIVs (outbreak group A) are relatively homogeneous and derived by the event of multiple genetic reassortment of Eurasian and North A......
Scaffolds from biomaterials: advantages and limitations in bone and tissue engineering
Biologia - Tập 71 - Trang 353-366 - 2016
Nowadays, there has been immense progress in developing materials to support transplanted cells. Nevertheless, the complexity of tissues is far beyond what is found in the most advanced scaffolds. This article reviews the types of biomaterials and their resulting scaffolds in the bio-engineering of bone and tissues by presenting an overview of the characteristics of ideal scaffold in tissue engine......
Community composition and cold tolerance of soil Collembola in a collapse karst doline with strong microclimate inversion
Biologia - Tập 70 - Trang 802-811 - 2015
The study compared communities of soil Collembola along the inversed microclimatic gradient of the collapse doline of the Silická ľadnica Ice Cave (Slovakia) in spring and autumn of 2005. Kruskal-Wallis ANOVA and the Mann- Whitney test revealed significant differences in abundance between sites and both seasons. Significantly higher abundance means and species richness were observed at most sites ......
Correction to: Sordaria fimicola-like ascomycete isolated from Pinus coulteri. Needles in Slovakia
Biologia - Tập 73 - Trang 561-561 - 2018
The original version of this article has been corrected to reflect the proper rendering of Fig. 1 after it was reported by the author that Fig. 1 was not loaded properly and did not show all of the necessary information. The original article has been corrected.
Morphometric aspects and growth modeling of exotic bivalve blood cockle Scapharca inaequivalvis from the Black Sea, Turkey
Biologia - Tập 69 - Trang 1707-1715 - 2015
This study was planned to determine biometric features and relationships between them in blood cockle, Scapharca inaequivalvis, a benthic exotic bivalve species of the Black Sea, Turkey during a period of 12 months. Over the study, 4,543 samples were collected and their shell length (SL), width (SWi), thickness (ST) and weight (SWe), as well as total (TW) and meat weights (MW) were measured. SL ch......
Analyses of sexual reproductive traits in Dactylorhiza majalis: a case study from East Germany
Biologia - Tập 75 - Trang 507-521 - 2020
The orchid species Dactylorhiza majalis is endangered by continuing habitat destruction and fragmentation. This requires more detailed information with respect to its sexual reproduction, which is especially relevant for Germany, where from 10 % to 30 % of the world-wide remaining populations grow. In the present study, we determined both the numbers of growing and flowering individuals per stand ......
Pollen and seed morphology of the genus Cistanche (Orobanchaceae) in Iran
Biologia - Tập 65 - Trang 615-620 - 2010
The pollen grains and seeds in six species of Cistanche distributed in Iran were examined. Detailed morphological descriptions of pollen and seed are given for each species. Four microsculpturing patterns are recognized on pollen surface among the species studied: microhammulate, microscabrate, microornate and microgemmate. The seed coat sculpturing among the studied species is constantly alveolat......
Morpho-histological study on shoot bud regeneration in cotyledon cultures of pepper (Capsicum annuum)
Biologia - Tập 62 - Trang 704-710 - 2007
Adventitious organogenetic structures were produced in vitro using cotyledon explants excised from 14 day-old pepper seedlings. The best response was observed on MS medium containing 5.7 μM indole-3-acetic acid and 8.8 μM 6-benzylaminopurine. However, when transferred onto elongation medium (MS + 2.8 μM gibberellic acid), these structures frequently developed into leaf-like features rather than in......
