Directionality and processivity of molecular motors

Current Opinion in Cell Biology, 2002
Analysis of a mutant with altered directionality has led to new insights into motor directionality. The prediction from current models for processivity of a two-heads-bound state has been confirmed by electron microscopy for myosin V and by unbinding experiments for kinesin.

Dynamics of Molecular Photoionization Processes

International Journal of Quantum Chemistry, 1984
Recent theoretical and experimental advances have shown that shape and autoionizing resonances play an important role in the dynamics of molecular photoionization. With the increasing availability of synchrotron radiation and improvements in electron spectrometers, continued progress can be expected in the studies of resonance features in the ...

Splicing systems and molecular processes

Proceedings of 1997 IEEE International Conference on Evolutionary Computation (ICEC '97), 2002
The splicing system concept and its history are reviewed. A proposed laboratory splicing scheme is discussed. This scheme has suggested that splicing schemes be regarded as specifying not only languages, but also dynamical systems. As an example of a new formal result on splicing languages, a theorem is stated that characterizes those regular languages

Antigen processing at the molecular level

Immunology Today, 1987
The recognition of antigen by helper T cells is one of the key steps in the induction of an immune response. Most helper T cells recognize a processed form of antigen; here, Paul Allen reviews the definition of antigen processing and shows that it may take at least three forms which depend upon the antigen and T cells being examined.

The Molecular Inflammatory Process in Aging

Antioxidants & Redox Signaling, 2006
Emerging pathological evidence indicates that major chronic aging-related diseases such as atherosclerosis, arthritis, dementia, osteoporosis, and cardiovascular diseases, are inflammation-related. In this review, inflammation is examined as a possible underlying basis for the molecular alterations that link aging and age-related pathological processes.

Excitation Processes in Molecular Nitrogen

Nature, 1948
IN controlled electron experiments it has been usually assumed1 that in the emission of the triplet bands of molecular nitrogen, transitions to the upper levels of the band systems concerned come about directly as a result of collisions of the first kind between molecules in the ground-state X1Σ+g and fast electrons.

Invertebrate molecular neuroimmune processes

Brain Research Reviews, 2000
During the course of evolution, invertebrates and vertebrates have kept in common similar signaling molecules e.g. neuropeptides, opiates etc... Complete hormonal-enzymatic systems such as the opioid-opiate-cannabinoid systems have been found in both nervous central and immune systems of these animals.

Information processing in molecular systems

Biosystems, 1972
Abstract Information processing, or selective dissipation, is mediated by switching elements in classical systems and by enzyme catalysis in biochemical systems. There are important differences in the character of this dissipation (from the standpoint of energy and control) in self-reproducing systems based on molecular interactions and those based ...
