My research has two primary goals. The first is to elucidate the molecular basis of visual excitation and adaptation. The basic approach is to use electrophysiological and pharmacological techniques to study phototransduction of individual photoreceptor cells. Novem –Ap BY JOHN E. DOWLING. BIOLOGY LOST ONE of its towering figures of the twentieth century with the passing of George Wald. A student of Selig Hecht, the major researcher in visual physiology of his generation, Wald unraveled the nature of the light-sensing molecules found in photoreceptor cells and was the dominant force in his field for over forty years.
I am a graduate on molecular biology. My PhD is focused on yeast studies where I did gene knock-out, mutagenesis and screening for potential anti-malaria drugs. Thus, I am familiar with most of the "wet lab" skills for molecular/microbiology. Recently, I start working with a visual informatics team. The ability to store and distribute vitamin A inside the body is the main evolutionary adaptation that allows vertebrates to maintain retinoid functions during nutritional deficiencies and to acquire new metabolic pathways enabling light-independent production of cis retinoids. These processes greatly depend on enzymes that esterify vitamin A as well as associated retinoid binding proteins.

A large body of biochemical and physiological evidence suggests that absorption of a sin- gle photon by rhodopsin initiates the following chain of events (diagrammed in Fig. 11): 1. Excitation, in physics, the addition of a discrete amount of energy (called excitation energy) to a system—such as an atomic nucleus, an atom, or a molecule—that results in its alteration, ordinarily from the condition of lowest energy (ground state) to one of higher energy (excited state).

The subject was discussed initially in. INTRODUCTION. Visual pigments represent a group of G protein-coupled receptors (96, ) that are responsible for the capture of photons and the initiation of visual visual pigment consists of an integral membrane protein, opsin, and a chromophore, either cis-retinal or light sensitivity of the visual pigments is due to the chromophore, which is.
due to the structural modiﬁcation, as anticipated on the basis of DFT calculations. In conclusion, it was demonstrated that extension of the aromatic core of molecular motors is a viable strategy for red-shifting their excitation wavelength.
To this end, a novel molecular motor with a dibenzoﬂuorene lower half was designed and synthesized.
