Michael D, Valle B, Cox J, Kalns J, Fogt D
J Clin Sleep Med . 2013 Dec; 9(12):1325-31. PMID: 24340295
Study Objective: Determine whether a salivary biomarker of physical fatigue, referred to as the fatigue biomarker index (FBI), can discriminate a control group from a sleep deprived group when saliva...

Michael D, Daugherty S, Santos A, Ruby B, Kalns J
Accid Anal Prev . 2012 Jan; 45 Suppl:68-73. PMID: 22239935
Fatigue changed the composition of the small-molecular weight (sMW) proteome of saliva during a 10h session of moderate (70% of maximum ventilatory threshold) physical exertion. Saliva samples were collected from...

Fogt D, Cooke W, Kalns J, Michael D
Aviat Space Environ Med . 2011 Dec; 82(12):1104-9. PMID: 22195390
Introduction: Fatigue degrades cognitive performance, yet there is no universally accepted objective measure of fatigue. We tested whether fatigue arising from sleep deprivation can be quantified objectively using heart rate...

Fogt D, Kalns J, Michael D
Mil Med . 2011 Jan; 175(12):939-44. PMID: 21265297
Fatigue is known to impair cognitive performance, but it remains unclear whether concurrent common stressors affect cognitive performance similarly. We used the Stroop Color-Word Conflict Test to assess cognitive performance...

Imoukhuede P, Moss F, Michael D, Chow R, Lester H
Biophys J . 2009 Apr; 96(7):2949-60. PMID: 19348776
A high density of neurotransmitter transporters on axons and presynaptic boutons is required for the efficient clearance of neurotransmitters from the synapse. Therefore, regulators of transporter trafficking (insertion, retrieval, and...

Michael D, Tapechum S, Rohan J, Johnson J, Chow R
Ann N Y Acad Sci . 2009 Jan; 1152:7-17. PMID: 19161372
Fluorescent fusion proteins are an important tool for the study of vesicle trafficking and exocytosis, especially when combined with newer types of microscopy. We previously reported that the design of...

Michael D, Xiong W, Geng X, Drain P, Chow R
Diabetes . 2007 Feb; 56(5):1277-88. PMID: 17317765
In healthy individuals, plasma insulin levels oscillate in both fasting and fed states. Numerous studies of isolated pancreata and pancreatic islets support the hypothesis that insulin oscillations arise because the...

Michael D, Cai H, Xiong W, Ouyang J, Chow R
Trends Endocrinol Metab . 2006 Nov; 17(10):408-15. PMID: 17084640
According to the classical view, peptide hormones are stored in large dense-core vesicles that release all of their cargo rapidly and completely when they fuse with and flatten into the...

Oheim M, Michael D, Geisbauer M, Madsen D, Chow R
Adv Drug Deliv Rev . 2006 Oct; 58(7):788-808. PMID: 17055106
The aim of this article is to review the basic principles of two-photon excitation fluorescence (2PEF) microscopy and to compare the advantages and disadvantages of 2PEF imaging to other microscopy...

Michael D, Ritzel R, Haataja L, Chow R
Diabetes . 2006 Mar; 55(3):600-7. PMID: 16505221
Insulin vesicles contain a chemically rich mixture of cargo that includes ions, small molecules, and proteins. At present, it is unclear if all components of this cargo escape from the...
