DNA Origami‐Cyanine Nanocomplex for Precision Imaging of KRAS‐Mutant Pancreatic Cancer Cells

Advanced Science, EarlyView.
DNA origami‐cyanine (Do‐Cy) nanocomplexes are synthesized to selectively image KRAS‐mutant pancreatic cancer cells in the highly desmoplastic tumors. This study shows that the Do‐Cy nanocomplexes are preferentially internalized by cancer cells over other stroma cells via KRAS‐dependent macropinocytosis.

The changes in levels of blood cortisol, glucose, and oxygen saturation in type 2 diabetic patients during tooth extraction

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1449-1455, December 2022., 2022
Abstract Objectives The extraction of a tooth exacerbates the stress in diabetic patients leading to diabetic complications so the aim was to evaluate the changes in blood cortisol, glucose, and oxygen saturation in type 2 diabetic patients during tooth extraction to pay special attention during a routine surgical procedure.

Cholesterol-activated stress granules reduce the membrane localization of DRD2 and promote prolactinoma dopamine agonists resistance

Acta Neuropathologica Communications
Prolactinoma is the most prevalent pituitary neuroendocrine tumor and dopamine agonists (DAs) targeting dopamine D2 receptor (DRD2) are recommended as the first-line treatment. However, varying degrees of DA resistance limit patient benefit.

Generation of isogenic and homozygous MEN1 mutant cell lines from patient-derived iPSCs using CRISPR/Cas9

Stem Cell Research, 2023
MEN1, an autosomal dominant disorder caused by mutations in the tumor suppressor gene MEN1, manifests with co-occurrence of multiple endocrine/neuroendocrine neoplasms. An iPSC line derived from an index patient carrying the mutation c.1273C>T (p.Arg465*)

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.

Model predictive control for the prescription of antithyroid agents [PDF]

arXiv, 2023
Although hyperthyroidism is a common disease, the pharmaceutical therapy is based on a trial-and-error approach. We extend a mathematical model of the pituitary-thyroid feedback loop such that the intake of one antithyroid agent, namely methimazole (MMI), can be considered and use a model predictive control (MPC) scheme to determine suitable dosages.

DynPeak : An algorithm for pulse detection and frequency analysis in hormonal time series [PDF]

PLoS ONE 7, 7 (2012) e39001, 2011
The endocrine control of the reproductive function is often studied from the analysis of luteinizing hormone (LH) pulsatile secretion by the pituitary gland. Whereas measurements in the cavernous sinus cumulate anatomical and technical difficulties, LH levels can be easily assessed from jugular blood.

Clinical and Pathological Aspects of Silent Pituitary Adenomas

Journal of Clinical Endocrinology and Metabolism, 2018
Context Silent pituitary adenomas are anterior pituitary tumors with hormone synthesis but without signs or symptoms of hormone hypersecretion. They have been increasingly recognized and represent challenging diagnostic issues.

Coordinated Role of Autophagy and ERAD in Maintaining Neuroendocrine Function by Preventing Prohormone Aggregation

Advanced Science, EarlyView.
By studying the maturation mechanisms of vasopressin (AVP), this manuscript identifies FAM134B‐mediated ER‐phagy as a critical pathway for degrading both aggregated proAVP and the key ERAD component, HRD1. HRD1 induction mitigates proAVP aggregation and support AVP neuron function in the absence of autophagy.
