INTRODUCTION Pityriasis rubra pilaris is an uncommon inflammatory and hyperproliferative dermatosis of juvenile or adult onset. The etiology of the disease is still unknown. CASE PRESENTATION We present the cases of two Caucasian men aged 53 and 48 who presented with pityriasis rubra pillaris type 1; both patients also exhibited an abnormal immunological profile. CONCLUSION Pityriasis rubra...

Since European settlement, hardwood dominated forests of the Upper American Midwest have undergone compositional changes due to fire suppression and changes in land use. It is not clear how these changes affect songbirds during spring migration. In 2009 and 2010, we quantified foraging behavior by migratory songbirds during spring migration and collected data on tree and sapling diversity in th...

Numerous parameters affect the quality of honey from different beehive types (Albert – Žindaršić AŽ, Langstroth – Roott LR i Dadant – Blatt DB), i.e. the material of beehives are made of, the origin of queen bees (natural and selected), etc. Our research focuses on the influence of the botanic origin of honey plants (Tilia sp. L. (lime), Amorpha fructirosa L. (desert false indigo), Helianthus a...

Ulmus pumila is an elm species, non-native to the USA that hybridizes with Ulmus rubra. In order to study the genetic structure and hybridization patterns between these two elm species, we developed 15 primer pairs for microsatellite loci in U. rubra and tested their cross-amplification in U. pumila. All 15 primers amplified in both species, 11 of which possessed species-specific alleles. Eight...

The endosperm cells of the American basswood Tilia americana are favorable experimental material for investigating the birefringence of living plant spindles and anaphase movement of chromosomes. The behavior of the chromosomes in anaphase and the formation of the phragmoplast are unique. The numerous (3 n equals 123), small chromosomes move in precise, parallel rows until midanaphase when they...

The etiologic agent of plague, Yersinia pestis, includes two subspecies, of which Y. pestis subsp. microtus contains the strains that cause only occasional diseases in humans that are not accompanied by human-to-human transmission. Here, we report the draft genome sequences of 19 Y. pestis strains (across 6 biovars of Y. pestis subsp. microtus).

Incursion of the urchin Centrostephanus rodgersii into Tasmania, Australia, and its establishment at high densities raises questions about its potential interactions with another large herbivore on subtidal rocky reefs, the commercially fished abalone Haliotis rubra. Surveys on the southeast coast of Australia show a negative relationship between densities of C. rodgersii and H. rubra at severa...

in this study, we measured the composition and free radical scavenging activity of several species of nuts, namely, torreya grandis, carya cathayensis,and myrica rubra. the nut kernels of the aforementioned species are rich in fatty acids, particularly in unsaturated fatty acids, and have 51% oil content. t. grandis and c. cathayensis are mostly produced in zhejiang province. the trace elements...

Peritoneal exÃodate cells (PEC) harvested from mice after i.p. injection of squalene-treated cell wall skeleton of Nocardia rubra (N. rubra-CWS) demonstrated vigorous cytolytic activity in vitro toward tumor target cells. Fractionation of these PEC by adherence to plastic dishes showed that the cytolytic activity in PEC was associated with an adherent phagocytic cell. In duction of the cytolyti...
