Integral field spectroscopy of nitrogen overabundant blue compact dwarf galaxies [PDF]

open access: yes, 2011
We study the spatial distribution of the physical properties and of oxygen and nitrogen abundances in three Blue Compact Dwarf Galaxiess (HS 0128+2832, HS 0837+4717 and Mrk 930) with a reported excess of N/O in order to investigate the nature of this ...

The Trichinella Super‐Pangenome Reveals the Evolution of Encapsulation and Predicted Host–Parasite Protein Interactions

open access: yesAdvanced Science, EarlyView.
ABSTRACT The muscle capsule of Trichinella is a critical structure that impedes immune attacks and drug penetration, yet the molecular mechanisms underlying its formation remain poorly understood. Using a high‐quality super‐pangenome comprising 12 Trichinella species, we compared extensive genomic variations between encapsulating and non‐encapsulating ...

Canthin-6-one Alkaloids and a Tirucallanoid from Eurycoma longifolia and Their Cytotoxic Activity against a Human HT-1080 Fibrosarcoma Cell Line

open access: yesNatural Product Communications, 2010
Phytochemical investigation of the stems of Eurycoma longifolia Jack led to the isolation of two new canthin-6-one alkaloids, 4,9-dimethoxycanthin-6-one (1) and 10-hydroxy-11-methoxycanthin-6-one (2), and a new tirucallane-type triterpenoid, 23,24,25 ...

The first WASP public data release [PDF]

open access: yes, 2010
The WASP (wide angle search for planets) project is an exoplanet transit survey that has been automatically taking wide field images since 2004. Two instruments, one in La Palma and the other in South Africa, continually monitor the night sky, building ...

A Modular and Programmable Cas13d Platform for RNA Single Nucleotide Variant Detection

open access: yesAdvanced Science, EarlyView.
A scenario‐guided Cas13d platform enables configurable single nucleotide variant ribonucleic acid diagnostics through rule‐based guide design and ribonucleic acid binding domain engineering, supporting amplification‐free ultrasensitive detection and amplification‐coupled robust detection for accurate mutation classification in clinical tumor specimens.

Ustrój polityczny Islandzkiej Wolnej Wspólnoty w latach 930-1269

open access: yesCzasopismo Prawno-Historyczne, 2006
„Islandia została zasiedlona przez Norwegów w czasach Haralda Pięknowłosego, syna Haralda Czarnego (...) Było to w 870 roku po narodzeniu Chrystusa. Rozpoczęła się wtedy tak wielka emigracja z Norwegii, że król Harald zabronił jej, gdyż obawiał się, iż ...

Keratinocytes from human skin respond as typical immune cells after the stimulation with _Trichophyton rubrum_ [PDF]

open access: yes, 2007
_Trichophyton rubrum_ is the main agent causing dermatophytosis (1). Keratinocytes are considered to be the first physical barrier of defense against pathogens (2). But not only a physical barrier.

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

open access: yesAdvanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...

Hydrogels Under Superchaotropic Control: Polyoxometalate Stabilization and pH‐Responsive Crosslinking in Cellulose Ether Solutions

open access: yesAngewandte Chemie, EarlyView.
Superchaotropic binding of Keggin polyoxometalates (POMs) to non‐ionic biopolymers like cellulose ethers (CEs) stabilizes otherwise hydrolytically unstable POMs in aqueous solution and allows conversion of pH‐nonresponsive polymers into pH‐responsive soft materials. The pH‐driven conversion from plenary to lacunary POMs switches superchaotropic binding
