BACKGROUND Dendritic cells (DC) linking innate and adaptive immune responses are present in human lungs, but the characterization of different subsets and their role in COPD pathogenesis remain to be elucidated. The aim of this study is to characterize and quantify pulmonary myeloid DC subsets in small airways of current and ex-smokers with or without COPD. METHODS Myeloid DC were characteriz...

This study was conducted to evaluate the antimicrobial and antioxidant activities of the hexane and methanol extracts of the aboveground parts and roots of some Astragalus species grown in the vicinity of Erzurum, located in the eastern Anatolia, Turkey. The methanol extract, which was obtained from the aboveground parts of Astragalus species, exhibited mild free radical scavenging activity pro...

Rodzaj Equisetum L. jest obecnie jedynym żyjącym przedstawicielem, niegdyś bardzo licznej w gatunki rodziny Equisetaceae. Do dziś przetrwało zaledwie około 15 gatunków. Jednym z nich skrzyp błotny. Skrzypy nie były dotąd szczegółowo badane pod względem cytochemicznym. Niniejsza praca przedstawia krótką charakterystykę morfologiczną i anatomiczną gatunku, jego zróżnicowanie taksonomiczne, rozmie...

Regressions of ex post changes in floating exchange rates on appropriate interest differentials typically imply that the high-interest rate currency tends to appreciate, the "forward discount puzzle". Using data from the European Monetary System, we find that a large part of the forward discount puzzle vanishes for regimes of fixed exchange rates. That is, deviations from uncovered interest par...

We employed a glycogen-depleting session of exercise followed by a low-carbohydrate (CHO) diet to investigate modifications that occur in muscle sarcoplasmic reticulum (SR) Ca(2+)-cycling properties compared with low-CHO diet alone. SR properties were assessed in nine untrained males [peak aerobic power (Vo(2 peak)) = 43.6 +/- 2.6 (SE) ml.kg(-1).min(-1)] during prolonged cycle exercise to fatig...

B7-DC molecules are known to function as ligands on antigen-presenting cells (APCs), enhancing T cell activation. In this study, cross-linking B7-DC with the monoclonal antibody sHIgM12 directly potentiates dendritic cell (DC) function by enhancing DC presentation of major histocompatibility complex-peptide complexes, promoting DC survival; and increasing secretion of interleukin (IL)-12p70, a ...

The effects of exercise and diet on sarcoplasmic reticulum Ca(2+)-cycling properties in female vastus lateralis muscle were investigated in two groups of women following four different conditions. The conditions were 4 days of a low-carbohydrate (Lo CHO) and glycogen-depleting exercise plus a Lo CHO diet (Ex + Lo CHO) (experiment 2) and 4 days of normal CHO (Norm CHO) and glycogen-depleting exe...

The article is part of the series, devoted to studies on Equisetum species occurring in Poland. described here, arvense L. – field horsetail, regarded as typical for entire genus. Among others, some morphological and anatomical characteristics species, its taxonomic diversity, distribution association with specihc habitat types, well threats, traditional use life cycle are presented below. phyt...
