Mechanisms of sulfonylurea's stimulation of insulin secretion in vivo: selective amplification …


NK Pørksen, SR Munn, JL Steers, O Schmitz, … - Diabetes, 1996 - Am Diabetes Assoc
Although sulfonylureas enhance insulin secretion, it is unknown whether these
hypoglycemic chemicals stimulate insulin secretion through the augmentation of
the pulsatile or basal modes of insulin release. Enhanced pulsatile insulin ...

Effects of glucose ingestion versus infusion on pulsatile insulin secretion. The incretin effect …


N Porksen, S Munn, J Steers, JD Veldhuis, PC … - Diabetes, 1996 - Am Diabetes Assoc
In the present studies, we used a recently validated canine model to determine
1) if glucose ingestion stimulates insulin secretion by amplifying the pulsatile
component of insulin release, and if so, 2) whether this effect is achieved ...

Glucagon-like peptide 1 increases mass but not frequency or orderliness of pulsatile insulin …


N Pørksen, B Grøfte, B Nyholm, JJ Holst, SM … - Diabetes, 1998 - Am Diabetes Assoc
Glucagon-like peptide 1 (GLP-1) is a peptide hormone that is released from the
gut after luminal stimulation. The hormone is a potent insulin secretagogue and
is a potential novel pharmaceutical adjuvant in the treatment of NIDDM. ...

Augmented effect of short-term pulsatile versus continuous insulin delivery on lipid …


O Schmitz, SB Pedersen, A Mengel, N … - Metabolism, 1994 - Elsevier
The present study was designed to examine the effect of pulsatile versus
continuous insulin delivery on glucose and lipid metabolism in insulin-resistant
subjects. Six obese women (body mass index, 40.0 ± 2.8 kg/m 2 ) underwent ...

In humans at least 75% of insulin secretion arises from punctuated insulin secretory bursts

- physiology.org
N Porksen, B Nyholm, JD Veldhuis, PC Butler … - American Journal of Physiology- Endocrinology And …, 1997 - Am Physiological Soc
Detection of insulin secretory bursts in peripheral blood is hampered by hepatic
insulin extraction, dilution in the systemic insulin pool, and time-delayed
damping of secretory burst amplitude. Previous studies in dogs in vivo and ...

INSULIN, LIKE THE hypothalamopituitary hormones, is secreted in a pulsatile
manner (4, 18). However, in contrast to pituitary hormones, the optimal sampling
intensity, duration, and vascular site for insulin have not been fully ...
