Induction of Gastrin Expression in Gastrointestinal Cells by Hypoxia or Cobalt Is Independent of Hypoxia-Inducible Factor (HIF)
(ENDOCRINE SOC, 2012-07-27)
Gastrin and its precursors have been shown to promote mitogenesis and angiogenesis in gastrointestinal tumors. Hypoxia stimulates tumor growth, but its effect on gastrin gene regulation has not been examined in detail. ...
p21-activated kinases and gastrointestinal cancer
(ELSEVIER SCIENCE BV, 2013-01-01)
p21-activated kinases (PAKs) were initially identified as effector proteins downstream from GTPases of the Rho family. To date, six members of the PAK family have been discovered in mammalian cells. PAKs play important ...
Melatonin supplementation in patients with complete tetraplegia and poor sleep.
People with complete tetraplegia have interrupted melatonin production and commonly report poor sleep. Whether the two are related is unclear. This pilot study investigated whether nightly supplementation of 3 mg melatonin ...
Prevention of hypothermia in patients undergoing orthotopic liver transplantation using the humigard (R) open surgery humidification system: a prospective randomized pilot and feasibility clinical trial
(BIOMED CENTRAL LTD, 2017-01-23)
BACKGROUND: Perioperative thermal disturbances during orthotopic liver transplantation (OLT) are common. We hypothesized that in patients undergoing OLT the use of a humidified high flow CO2 warming system maintains higher ...
Spatial morphological and molecular differences within solid tumors may contribute to the failure of vascular disruptive agent treatments
(BIOMED CENTRAL LTD, 2012-11-15)
BACKGROUND: Treatment of solid tumors with vascular disrupting agent OXi4503 results in over 90% tumor destruction. However, a thin rim of viable cells persists in the tumor periphery following treatment, contributing to ...
Comparative Evaluation of Crystalloid Resuscitation Rate in a Human Model of Compensated Haemorrhagic Shock
(LIPPINCOTT WILLIAMS & WILKINS, 2016-08-01)
INTRODUCTION: The most effective rate of fluid resuscitation in haemorrhagic shock is unknown. METHODS: We performed a randomized crossover pilot study in a healthy volunteer model of compensated haemorrhagic shock. Following ...
Long-Term Persistence of Hormonal Adaptations to Weight Loss
(MASSACHUSETTS MEDICAL SOC, 2011-10-27)
BACKGROUND: After weight loss, changes in the circulating levels of several peripheral hormones involved in the homeostatic regulation of body weight occur. Whether these changes are transient or persist over time may be ...
A common mechanism of clinical HIV-1 resistance to the CCR5 antagonist maraviroc despite divergent resistance levels and lack of common gp120 resistance mutations
(BIOMED CENTRAL LTD, 2013-04-20)
BACKGROUND: The CCR5 antagonist maraviroc (MVC) inhibits human immunodeficiency virus type 1 (HIV-1) entry by altering the CCR5 extracellular loops (ECL), such that the gp120 envelope glycoproteins (Env) no longer recognize ...
Ketosis and appetite-mediating nutrients and hormones after weight loss
(NATURE PUBLISHING GROUP, 2013-07-01)
BACKGROUND/OBJECTIVES: Diet-induced weight loss is accompanied by compensatory changes, which increase appetite and encourage weight regain. There is some evidence that ketogenic diets suppress appetite. The objective is ...
