Nitric oxide-sensitive guanylyl cyclase is differentially regulated by nuclear and non-nuclear estrogen pathways in anterior pituitary gland. [PDF]

open access: yesPLoS ONE, 2011
17β-estradiol (E2) regulates hormonal release as well as proliferation and cell death in the pituitary. The main nitric oxide receptor, nitric oxide sensitive- or soluble guanylyl cyclase (sGC), is a heterodimer composed of two subunits, α and β, that ...

Monitoring pharmacodynamic and molecular drug targets in liquid biopsy: Exploratory study in liver cancer with modelling of EGFR Receptor engagement

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Liquid biopsy is minimally invasive (compared with tissue biopsy) and has previously been used to generate systems data regarding drug elimination via hepatic enzymes and transporters. This study extends quantitative assessment of systems parameters in liquid biopsy to pharmacodynamic (PD) and disease markers relevant to cancer development

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Estrogens sensitize anterior pituitary gland to apoptosis

open access: yesAmerican Journal of Physiology-Endocrinology and Metabolism, 2004
Tissue homeostasis results from a balance between cell proliferation and cell death by apoptosis. Estradiol affects proliferation as well as apoptosis in hormone-dependent tissues. In the present study, we investigated the apoptotic response of the anterior pituitary gland to lipopolysaccharide (LPS) in cycling female rats, and the influence of ...

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Anticipatory Stress in Medical Students Before Their First Cadaver Experience: A Physiological Component of Cadaver‐Based Anatomy Education

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Cadaver‐based anatomy education represents a unique biological and sensory experience that may elicit significant physiological responses. However, little is known about the anticipatory phase prior to initial exposure, particularly when evaluated using objective biomarkers.

Lymphocytic infundibuloneurohypophysitis: A rare case report

open access: yesMAMC Journal of Medical Sciences, 2015
Lymphocytic hypophysitis is a neuroendocrine disorder characterized by autoimmune infiammation of the pituitary gland with various degrees of pituitary dysfunction. Coexistence of other autoimmune conditions is reported in the vast majority of cases. The

Developmental Morphometry of the Paranasal Sinuses in Subjects Aged 1–25 Years: A Computed Tomography Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The present study aimed to evaluate the developmental morphometry of the paranasal sinuses using computed tomography (CT) in subjects aged 1–25 years and to characterize age‐related changes in sinus dimensions, volume, and surface area throughout childhood, adolescence, and young adulthood.

Pituitary Adenoma: A Short Illustrative Review

open access: yesIndian Journal of Neurosurgery, 2016
The pituitary gland is located below the brain in a depression of sphenoid bone known as sella turcica. It controls most of the body's endocrine functions via the secretion of various hormones into the circulatory system.

Identification of a Functional CYP2C8 Variant Allele that Alters Splicing, Reduces Protein Expression, and Increases Drug Exposure

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
This study investigated genetic determinants of the pharmacokinetics of the CYP2C8 index drugs repaglinide and gemfibrozil, and their interaction in healthy participants. Sequencing data from a study with montelukast revealed a novel functional CYP2C8 allele (rs2071426, CYP2C8*19), predicted to create an intronic splice donor site.
