Responses of sympathoadrenal and renin angiotensin systems to stress stimuli in humans during real and simulated microgravity.

Journal of gravitational physiology : a journal of the International Society for Gravitational Physiology

Kvetnansky R, Koska J, Ksinantova L, Noskov VB, Blazicek P, Marko M, Macho L, Grigoriev AI, Vigas M.
PMID: 14977002
J Gravit Physiol. 2002 Jul;9(1):P79-80.

Changes of plasma hormone levels were investigated in human subjects after exposure to physical exercise (WL) and insulin induced hypoglycemia (ITT) during space flight or after head down bed rest (HDBR). Exaggerated responses of plasma epinephrine (EPI), norepinephrine (NE)...

Repeated immobilization stress alters tyrosine hydroxylase, corticotropin-releasing hormone and corticosteroid receptor messenger ribonucleic Acid levels in rat brain.

Journal of neuroendocrinology

Mamalaki E, Kvetnansky R, Brady LS, Gold PW, Herkenham M.
PMID: 21554656
J Neuroendocrinol. 1992 Dec;4(6):689-99. doi: 10.1111/j.1365-2826.1992.tb00220.x.

In situ hybridization histochemistry was used to localize and quantify the effects of acute and repeated immobilization stress on mRNA levels of tyrosine hydroxylase (TH) in catecholaminergic neurons in the locus ceruleus and substantia nigra and on mRNA levels...

Glucocorticoid withdrawal affects stress-induced changes of urocortin 2 gene expression in rat adrenal medulla and brain.

Journal of neuroendocrinology

Tillinger A, Horváthová Ľ, Nostramo R, Serova LI, Kvetňanský R, Sabban EL, Mravec B.
PMID: 29604138
J Neuroendocrinol. 2018 Mar 31;e12595. doi: 10.1111/jne.12595. Epub 2018 Mar 31.

Corticotropin-releasing factor is well known activator of the hypothalamic-pituitary-adrenocortical axis, that represents crucial system participating on stress response of the organism. Urocortins are members of the corticotropin-releasing factor family of peptides with proposed effects on neuroendocrine and behavioral stress...

Remote controlled equipment for multiple blood withdrawal in gravitational physiology experiments.

Journal of gravitational physiology : a journal of the International Society for Gravitational Physiology

Frollo I, Banic B, Mravec B, Jurani M, Greksak M, Macho L, Kvetnansky R.
PMID: 15002604
J Gravit Physiol. 2002 Jul;9(1):P339-40.

Electro-mechanical equipment for multiple blood withdrawal from small experimental animals applied to a centrifuge with maximal 6g gravitational overloading has been developed and tested. The equipment consists of a transmitter and receiver equipped by microcomputers. Active rotor stepping motors...

Immobilization Stress Elevates GTP Cyclohydrolase I mRNA Levels in Rat Adrenals Predominantly by Hormonally Mediated Mechanisms.

Stress (Amsterdam, Netherlands)

Serova LI, Nankova B, Kvetnansky R, Sabban EL.
PMID: 9787239
Stress. 1997 May;1(3):135-144. doi: 10.3109/10253899709001103.

GTP cyclohydrolase I (GTPCH) is the rate-limiting enzyme in the biosynthesis of tetrahydrobiopterin, the cofactor for catecholamine, indolamine and nitric oxide biosynthesis. In this study we examined the effect of immobilization stress on GTPCH mRNA levels and the mechanism(s)...
