The forkhead box subclass O (FoxO) family of proteins is a group of highly evolutionary conserved transcription factors that regulate various cellular processes and embryonic development. Dysregulated expressions of FOXO genes have been identified...

Interest in lysosomal storage disorders, a collection of more than 4 inherited metabolic disorders, has increased because of new therapy options such as enzyme replacement, stem cell transplantation, and substrate reduction therapy. We developed a...

Santos, J.E.; Way, B., 2015: Neutral Black Rings in Five Dimensions are Unstable. We study nonaxisymmetric linearized gravitational perturbations of the Emparan-Reall black ring using numerical methods. We find an unstable mode whose onset lies within the "fat" branch of the black ring and continues into the "thi...

Pre-dispersal seed predation may have important effects on population dynamics and trait evolution in plants. In this review, we first present a conceptual framework of the strength of pre-dispersal seed predation and its variation in space and ti...

Out of 154 genera belonging to 65 families, 38 genera belonging to 12 families were found to be the most interesting, both with regard to chemical composition of the majority of spp. studied and to their medicinal properties which are attributed t...

Logan R.A.; Zachary C.B., 1989: Outcome of carbon dioxide laser therapy for persistent cutaneous viral warts. Twenty-two adults with persistent, symptomatic viral warts on the hands or feet which had failed to respond to conventional therapy were treated by carbon dioxide (CO2) laser ablation under local anaesthesia. Four patients did not return for follo...

Shankar, A.H.; Titus, R.G., 1993: Leishmania major-specific, CD4+, major histocompatibility complex class II-restricted T cells derived in vitro from lymphoid tissues of naive mice. Several studies indicate that the outcome of experimental murine cutaneous leishmaniasis caused by Leishmania major (Lm) is determined by immunological events occurring shortly after infection. These events lead to outgrowth of either protective C...

Gehenn, K.; Reed, J., 2011: Tetrad selectivity in polarity-driven switch peptides: the best turn is not always the best nucleation site. In some naturally occurring protein sequences, an abrupt, concerted refolding from β-sheet to helical conformation occurs when the polarity of the surrounding medium drops below a critical level. This switch-like behaviour was first observed on t...
