Über spezialisierte Verbreitungseinrichtungen anatolischer Galieae
1971
Summary Some annual species of the Rubiaceae native in Anatolia are specialized in their methods of seed dispersal. Contrary to other members of the genus, the frucitficence of Cruriata articulata with its persisting bracts falls to pieces which act as ‘surface:rollers’ transported by the wind. Valantia hispida and Callipeltis cucullaria are heterodissmeniate. Some of the mericarps arc dispersed by different agents, the other ones stay attached to the plant, showing a form of atelechory, a common phenomenon in arid regions. Other aberrant forms of dissemination are studied.
Analysis of linear alkylbenzene samples with a camera-based equipment
2017
Nestemäisiä tuikeaineita hyödyntävät ilmaisimet ovat saaneet jalansijaa neutriinofysiikassa viime vuosikymmeninä. Perinteisiin Cherenkovin ilmaisimiin niiden etu on suurempi hiukkasten vuorovaikutuksesta aiheutuvan valon tuotto. Lisäksi edullisten, suhteellisen ympäristöystävällisten ja optisesti kirkkaiden tuikeaineyhdisteiden (bentseenin alkyylijohdannaiset) saatavuus mahdollistaa yhä suurempien ilmaisimien rakennuksen. Nestemäisten tuikeaineiden ongelmana on kuitenkin niiden taipumus kerätä epäpuhtauksia itseensä ja niiden muutosalttius UV-säteilyn ja korkeiden lämpötilojen vaikutuksesta. Muutokset heikentävät tuikeaineiden valon tuottoa, ja siksi nestemäisten tuikeaineiden puhdistusta j…
Callistemon citrinus and Cistus salvifolius, Two New Hosts of Phytophthora taxon niederhauserii in Italy.
2009
Bottlebrush (Callistemon citrinus (Curtis.) Skeels., Myrtaceae) and rock rose (Cistus salvifolius L., Cistaceae) are evergreen shrubs native to Australia and the Mediterranean Region, respectively. In the spring of 2003, approximately 2% of a nursery stock of 12-month-old potted plants of C. citrinus and 8% of a nursery stock of 12-month-old potted plants of Cistus salvifolius grown in the same nursery in Sicily, showed symptoms of leaf chlorosis, defoliation, and wilt associated with root and collar rot. A Phytophthora species was consistently isolated from roots and basal stems on BNPRAH selective medium (2). One isolate from rock rose (IMI 391708) and one from bottlebrush (IMI 391712) w…
Dynamic Changes in the Neurogenic Potential in the Ventricular–Subventricular Zone of Common Marmoset during Postnatal Brain Development
2020
AbstractEven after birth, neuronal production continues in the ventricular–subventricular zone (V–SVZ) and hippocampus in many mammals. The immature new neurons (“neuroblasts”) migrate and then mature at their final destination. In humans, neuroblast production and migration toward the neocortex and the olfactory bulb (OB) occur actively only for a few months after birth and then sharply decline with age. However, the precise spatiotemporal profiles and fates of postnatally born neurons remain unclear due to methodological limitations. We previously found that common marmosets, small nonhuman primates, share many features of V–SVZ organization with humans. Here, using marmosets injected wit…
Both Short- and Long-Acting D-1/D-2 Dopamine Agonists Induce Less Dyskinesia than l-DOPA in the MPTP-Lesioned Common Marmoset (Callithrix jacchus)
2002
Abstract The current concept of dyskinesia is that pulsatile stimulation of D-1 or D-2 receptors by l -DOPA or short-acting dopamine agonists is more likely to induce dyskinesia compared to long-acting drugs producing more continuous receptor stimulation. We now investigate the ability of two mixed D-1/D-2 agonists, namely pergolide (long-acting) and apomorphine (short-acting), to induce dyskinesia in drug-naive MPTP-lesioned primates, compared to l -DOPA. Adult common marmosets ( Callithrix jacchus ) were lesioned with MPTP (2 mg/kg/day sc for 5 days) and subsequently treated with equieffective antiparkinsonian doses of l -DOPA, apomorphine, or pergolide for 28 days. l -DOPA, apomorphine, …
CAMELINA SATIVA AS A CROP FOR DIVERSIFICATION OF AGRICULTURE AND AS A PRODUCER OF HIGH QUALITY OIL
2007
‘Camelina sativa’ is one of the oldest oil crops in Europe. Growing areas were reduced dramatically in 20-40-ties of the last century. Low price of rape oil and unclear composition of camelina oil were primary reasons of this process. Nevertheless, last years ‘Camelina sativa' attracted a great interest of scientists and oil processors as a crop for diversification of agriculture and, in the same time, for producing of the high quantity and quality oil for biofuel, feeding, food, and pharmacy (source of a-linolenic acid, linoleic acid and vitamins, especially E). In Latvia ‘Camelina sativa' is spread as a wild form but for the agriculture it is a new crop.The potential of me of ‘Camelina sa…
Assessment of computational methods for the analysis of single-cell ATAC-seq data
2019
Abstract Background Recent innovations in single-cell Assay for Transposase Accessible Chromatin using sequencing (scATAC-seq) enable profiling of the epigenetic landscape of thousands of individual cells. scATAC-seq data analysis presents unique methodological challenges. scATAC-seq experiments sample DNA, which, due to low copy numbers (diploid in humans), lead to inherent data sparsity (1–10% of peaks detected per cell) compared to transcriptomic (scRNA-seq) data (10–45% of expressed genes detected per cell). Such challenges in data generation emphasize the need for informative features to assess cell heterogeneity at the chromatin level. Results We present a benchmarking framework that …

Quaternary and subunit structure of Calliphora arylphorin as deduced from electron microscopy, electrophoresis, and sequence similarities with arthro…
1992
Arylphorin was purified from larvae of the blowfly Calliphora vicina and studied in its oligomeric form and after dissociation at pH 9.6 into native subunits. In accordance with earlier literature, it was electrophoretically shown to be a 500 kDa hexamer (1 x 6) consisting of 78 kDa polypeptides (= subunits). Electron micrographs of negatively stained hexamers show a characteristic curvilinear, equilateral triangle of 12 nm in diameter (top view) and a rectangle measuring 10 x 12 nm (side view). Alternatively, particles in the top view orientation exhibit a roughly circular shape 12 nm in diameter. Crossed immunoelectrophoresis revealed the presence of a major subunit type; the nature of a …
