It is known that leptin, an adipocyte-derived hormone, exerts a stimulatory effect on growth hormone (GH) secretion in various animal species. However, no previous study examined in vivo whether leptin affects the secretion of GH-releasing factor (GRF), somatostatin (SRIH), and some other closely relevant neurohormones in the hypothalamus. Therefore, in this study we investigated the effects of...

Ground reaction force (GRF) data from men and women are commonly pooled for analyses. However, it may not be justifiable to pool sexes on the basis of discrete parameters extracted from continuous GRF gait waveforms because this can miss continuous effects. Forty healthy participants (20 men and 20 women) walked at a cadence of 100 steps per minute across two force plates, recording GRFs. Two s...

Growth hormone (GH) secretory patterns were studied in a patient with ectopic growth hormone releasing factor (GRF) secretion and in normal men given continuous infusions of human growth hormone releasing factor (1-40)-OH (hGRF-40). In the patient with ectopic GRF secretion, GH secretion was pulsatile despite continuously elevated immunoreactive GRF levels. To determine if pulsatile GH secretio...

Central nervous system peptide and amino acid modulation of luteinizing hormone and prolactin secretion in the pig. Influence of opioids on LH secretion in gilts during the estrous cycle. D. Schams: Reg~lation of bovine intra-luteal function by peptide hormones. We have utilized active immunization against growth hormone releasing factor (GRF) to investigate relationships among somatotropin (ST...

In this paper we will investigate the properties of normality and strong normality of lattices and their relationships to zero-one measures. We will eventually establish necessary and sufficient conditions for lattices to be strongly normal. These properties are then investigated in the case of separated lattices.

In mammals, GRF and pituitary adenylate cyclase-activating polypeptide (PACAP) are encoded in separate genes. We report here that in the salmon a 4.5-kilobase gene contains five exons that encode the biologically active part of the GRF-like peptide (amino acids 1-32) on exon 4 and PACAP on exon 5. Analysis of two fish messenger RNAs reveals that a long precursor containing GRF and PACAP and a s...

BACKGROUND Because an excessive use of activator (formaldehyde + glutaraldehyde) is supposed to be responsible for later adverse events after the use of gelatin resorcin formalin (GRF) glue in surgery for acute aortic dissection, we have tried to use a minimum dose of activator when the GRF glue was applied. We compare our midterm surgical results for acute aortic dissection with and without th...

The precise control of gene regulation, and hence, correct spatiotemporal tissue patterning, is crucial for plant development. Plant microRNAs can constrain the expression of their target genes at posttranscriptional levels. Recently, microRNA396 (miR396) has been characterized to regulate leaf development by mediating cleavage of its GROWTH-REGULATING FACTOR (GRF) targets. miR396 is also prefe...

The purpose of this study was to examine the differences in the ground reaction force (GRF) patterns between elite and novice players during two types of handball shots, as well as the relationships between throwing performance and the GRF variables. Ball velocity and throwing accuracy were measured during jump shots and 3-step shots performed by 15 elite and 15 novice players. The GRF pattern ...
