Neurotransmitter receptors in the suprachiasmatic nucleus: circadian and developmental studies

The present audiographic study examined ligands for three receptors, chosen on the basis of high abundance of these receptors in the SCN relative to other brain regions([125I)VIP and [125I) angiotensin II) or the ability of pharmacological manipulations to affect the phase and period of circadian rhythms.

Morning and Afternoon Response to Exercise Using Two Test Protocols

The purpose was to investigate time of day on responses to two types of exhaustive cycle ergometer tests. Sixteen males performed six exercise tests: three - constant power protocol and three - incremental protocol. The first test was a learning trial; the other tests were performed one in the morning and one in the afternoon. ANOVA revealed that O2 deficit and lactate were higher in the afternoon than the morning. Regardless of test type, time to exhaustion tended to be higher in the afternoon… more

An Investlarks and Hearts: Circadian Mismatch and Effort Intensity

My experiment concerned the influence of chronobiological (circadian) rhythm on fatigue, effort, and cardiovascular (CV) response. It evaluated responses of morning people (Larks) presented an easy or difficult recognition memory task at a time congruent or incongruent with their rhythm. Based on an extension of a conceptual analysis of fatigue influence, my central prediction was that circadian rhythm would combine interactionally with task difficulty to determine effort and associated CV res… more

Final report

The originally funded project was geared to pursue research on regulation of photosystem II (PSII) in the cyanobacterium Synechococcus elongatus PCC 7942. We characterized a locus, psfR, (psbA stimulating factor) that affects expression of the psbAI gene, which encodes the PSII protein D1. Over-expression of psfR, which encodes a protein with receiver and pseudo-receiver domains, acts at the promoter region to elevate expression of psbAI and a subset of other loci. We reoriented the remainder o… more
