Isolation und molekulare Charakterisierung des Apoptose-induzierenden Metastasensuppressors C33/CD82 [PDF]

open access: yes, 2003
Die Apoptose ist ein genetisch codiertes Suizidprogramm, das es jeder eukaryontischen Zelle erlaubt, auf bestimmte endogene oder äußere Signale mit einem kontrollierten Degradations- und Absterbeprozess zu reagieren. Auf diese Weise werden dem Organismus

Characterizations of the Symmetric T(θ,q)-Classical Orthogonal q-Polynomials

open access: yes, 2022
In this paper, we give two characterizations for symmetric q-Dunkl-classical orthogonal polynomials. The first one is related to a spectral problem for a second-order linear q-difference differential operator.

Syntheses of C33-, C35-, and C39-Peridinin and Their Spectral Characteristics [PDF]

open access: yesOrganic Letters, 2009
Peridinin, a nor-carotenoid, exhibits an exceptionally high energy transfer efficiency to chlorophyll a in photosynthesis in the sea. This efficiency would be related to the unique structure of peridinin. To answer the question of why peridinin possesses the irregular C37 skeleton, we have achieved the synthesis of three peridinin derivatives.
