The discovery of programmed -1 frameshifting at the hexanucleotide shift site CGA_AAG, in addition to the classical X_XXY_YYZ heptanucleotide shift sequences, prompted a search for instances among eubacterial insertion sequence elements. IS1222 has a CGA_AAG shift site. A genetic analysis revealed that frameshifting at this site is required for transposition.

Intensive Tests und Betriebserfahrungen an AWI und IPP erlauben die Aufstellung von Qualitätsanforderungen für Videokonferenzen als Arbeitsmittel in der Programm-und Projektplanung in HGF und MPG. Diese werden gegliedert nach Anforderungen, medientechnischer und netzwerktechnischer Realisierung detailliert beschrieben. Empfehlungen für weitere Aktivitäten werden gegeben.

We suggest new pseudopolynomial and subexponential algorithms for Mean Payoff Games (MPGs). The algorithms are based on representing the MPG decision problem in the forms of non-standard and standard Linear Complementarity Problems (LCPs): find w, z ≥ 0 satisfying w = Mz + q and w · z = 0, (1.1) and monotonic iterative propagation of slack updates.

BACKGROUND Preconditioning with brief periods of ischemia protects the coronary endothelium against acute and chronic reperfusion injury, but the mechanisms of this endothelial protection remain unknown. We hypothesized that preconditioning protects endothelial cells through a decreased production of endothelial adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1), leading to a...

OBJECTIVES To evaluate the effect of mesenchymal stem cells (MSCs) and MSCs mixed with Matrixen as a cell carrier on the erectile dysfunction caused by bilateral cavernous nerve crushing injury. MATERIALS AND METHODS White male Sprague-Dawley rats were divided into 4 groups: sham-operated control group (n = 5), bilateral cavernous nerve crushing group (BCNC group, n = 10), BCNC administered w...

Although habitat restoration can play a key role in the conservation of imperiled species, for animals that demonstrate long migrations and complex life histories, reliance on physical restoration of isolated habitat patches comes with considerable uncertainty. Nevertheless, within freshwater ecosystems, stream restoration has become a major conservation focus, with millions of dollars spent an...

Overexpression of N-methylpurine DNA glycosylase (MPG) has been suggested as a possible gene therapy approach to sensitize tumor cells to the cell-killing effects of temozolomide, an imidazotetrazine-class chemotherapeutic alkylating agent. In the present study, we show that both elevated MPG expression and short hairpin RNA-mediated loss of DNA polymerase beta (Pol beta) expression in human br...
