Disturbance of each of the three hypothalamic-pituitary-end organ systems [hypothalamic-pituitary-thyroid (HPT), -adrenal (HPA), and -gonadal (HPG)] has been reported in depressive disorders. Little is known about potential reciprocal interaction among the three HP-end organ systems in patients with depressive disorders. The present pilot study examined selective HPA and HPG hormones in a detai...
Purpose: The present work describes the development and in vitro and in vivo evaluation of a mucoadhesive nanoparticulate docetaxel (DTX) formulation for intravesical bladder cancer therapy. Experimental Design: Mucoadhesive formulations based on hyperbranched polyglycerols (HPG), hydrophobically derivatized with C8/C10 alkyl chains in the core andmodified withmethoxy-polyethylene glycol (MePEG...
Annexin A5 (ANXA5), a member of the structurally related family of annexin proteins, is expressed in pituitary gonadotropes. We previously reported that ANXA5 expression is stimulated by gonadotropin-releasing hormone (GnRH). In the present study, we investigated ANXA5 expression in the anterior pituitary gland of GnRH-deficient mutant hypogonadal (hpg) mice. RT-PCR demonstrated that luteinizin...
The mechanism whereby fragments of streptokinase (SK) derived from its N terminus (e.g., SK1-59 or SK1-63) enhance the low plasminogen (PG)-activating ability of other fragments, namely SK64-386, SK60-414, SK60-387, and SK60-333 (reported previously), has been investigated using a synthetic peptide approach. The addition of either natural SK1-59, or chemically synthesized SK16-59, at saturation...
BACKGROUND Glycosylated hemoglobin, HbA 1c is the most acceptable measure of chronic glycemia. It is not widely available and/or affordable in Nigeria. The mean of the monthly fasting plasma glucose (MFPG) of the preceding 3 months is often used as surrogate for assessing chronic glycemia. OBJECTIVE To determine the relationships among fasting plasma glucose (FPG), 2-hour post-prandial glucos...
BACKGROUND Whereas an increase of neck circumference (NC) had been recently identified as a new independent cardiovascular disease (CVD) and metabolic syndrome risk factor, similar assessments concerning screen-detected diabetes mellitus (SDDM) have not been made. Thyroid gland volume (ThV) can potentially affect NC however the significance of this influence concerning the risk of NC-related di...
The present thesis deals with different aspects of population pharmacokinetic/ pharmacodynamic (PK/PD) modelling of the male hypothalamic-pituitary-gonadal (HPG) axis. The thesis consists of a summary report and five scientific research papers. An overview of the main topics covered in the thesis is provided in the summary report including PK/PD modelling in drug development, the pathological, ...
The kisspeptins are KiSS-1 gene-derived peptides that signal through the G protein-coupled receptor-54 (GPR54) and have recently been shown to be critical regulators of reproduction. Acute intracerebroventricular or peripheral administration of kisspeptin stimulates the hypothalamic-pituitary-gonadal (HPG) axis. This effect is thought to be mediated via the hypothalamic gonadotropin-releasing h...
Gonadotropin-inhibitory hormone (GnIH) is a hypothalamic neuropeptide that decreases gonadotropin synthesis and release by directly acting on the gonadotrope or by decreasing the activity of gonadotropin-releasing hormone (GnRH) neurons. GnIH is also called RFamide-related peptide in mammals or LPXRFamide peptide in fishes due to its characteristic C-terminal structure. The primary receptor for...
In many vertebrates, social interactions regulate reproductive capacity by altering the activity of the hypothalamic-pituitary-gonadal (HPG) axis. To better understand the mechanisms underlying social regulation of reproduction, we investigated the relationship between social status and one main component of the HPG axis: expression levels of gonadotropin-releasing hormone receptor (GnRH-R). So...
