Stability and Hopf bifurcation analysis for the hypothalamic-pituitary-adrenal axis model with memory [PDF]

, 2016
This paper generalizes the existing minimal model of the hypothalamic-pituitary-adrenal (HPA) axis in a realistic way, by including memory terms: distributed time delays, on one hand and fractional-order derivatives, on the other hand. The existence of a unique equilibrium point of the mathematical models is proved and a local stability analysis is ...

Associations of Historic Residential Pesticide Proximity With Proinflammatory Cytokine Levels in a Patient Population With and Without Chronic Rhinosinusitis (CRS)

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Residential proximity to commercial pesticide application has been associated with increased odds of developing chronic rhinosinusitis (CRS) with in vitro studies demonstrating cytotoxic dose‐dependent effects on sinonasal epithelia.

Stability and Hopf bifurcation analysis of a four-dimensional hypothalamic-pituitary-adrenal axis model with distributed delays [PDF]

, 2017
A four-dimensional mathematical model of the hypothalamus-pituitary-adrenal (HPA) axis is investigated, incorporating the influence of the GR concentration and general feedback functions. The inclusion of distributed time delays provides a more realistic modeling approach, since the whole past history of the variables is taken into account.

A Novel International Endoscopic Sphenoid Surgery Classification (IESSC): A Delphi Consensus

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Advancements in endoscopic sinus and skull base surgery created a need for standardized terminology to describe sphenoid sinus surgery. Although classification systems exist for other sinuses, one for endoscopic sphenoid sinus surgery is lacking.

Magnetic resonance imaging (MRI) findings in isolated growth hormone deficiency

The Turkish Journal of Pediatrics, 1998
In this study the presence of pituitary-hypothalamic abnormalities was searched by magnetic resonance (MR) imaging in 30 children (18 males and 12 females, aged 7.4 to 23 years) with isolated growth hormone deficiency (IGHD).

Long‐Term Particulate Matter Exposure May Increase Risk of Chronic Rhinosinusitis WIth Nasal Polyposis: Results from an Exposure‐Matched Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Particulate matter ⩽2.5 µm in diameter (PM2.5) and its role in chronic rhinosinusitis (CRS) pathogenesis have gained heightened attention. We previously demonstrated that PM2.5 exposure may bias the nasal mucosa in CRS toward a Type 2 inflammatory pathway.

Development of the anterior pituitary: diverse lineages of the stem/progenitor cells

Endocrine Journal
The pituitary gland is endocrine tissue composed of two distinct parts with different origins: the adenohypophysis (adenohypophyseal placode origin) and the neurohypophysis (neuroectoderm origin). Differentiation of endocrine cells in the pituitary gland
