“Do Not Kill Guinea Pig before Setting up Apparatus”: The Kymograph's Lost Educational Context [PDF]

open access: yes, 2016
The objects of science education are transformed, degraded and disappeared for many reasons, and sometimes take other things with them when they go. This close reading of an undergraduate physiology laboratory report demonstrates how the kymograph was ...

Vagus Nerve and Stomach Synucleinopathy in Parkinson’s Disease, Incidental Lewy Body Disease, and Normal Elderly Subjects: Evidence Against the “Body-First” Hypothesis

open access: yesmedRxiv, 2020
Background: Braak and others have proposed that Lewy-type α-synucleinopathy in Parkinson’s disease (PD) may arise from an exogenous pathogen that passes across the gastric mucosa and then is retrogradely transported up the vagus nerve to the medulla ...

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

open access: yesBMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Intestinal Barrier Glycosylation for Gut Physiology and Pathology

open access: yesBarrier Immunity, EarlyView.
ABSTRACT The intestinal barrier is a selective structure that safeguards the body from external threats while permitting nutrient absorption and immune surveillance. It consists of the outer mucus layer, the intermediate layer of intestinal epithelial cells (IECs), and the inner layer of immune cells. The proteins in the mucus layer and within IECs are

Syntopy of vagus nerve in the carotid sheath: A dissectional study of 50 cadavers

open access: yesLaryngoscope Investigative Otolaryngology, 2019
Background Vagus nerve anatomical position inside the carotid sheath is not clear in the literature. Nevertheless, monitoring laryngeal nerves during thyroid surgeries may damage big vessels in the carotid sheath (jugular vein; carotid artery).

Non recurrent laryngeal nerve with right aberrant subclavian artery in recurrent case of papillary carcinoma of thyroid: an interesting clinical entity. [PDF]

open access: yes, 2013
Background/objectives: A nonrecurrent laryngeal nerve is a rare anatomical variant and a routine preoperative imaging studies are not indicated. NRLN is related with absence of the brachiocephalic trunk and aberrant (mainly retroesophageal) course of ...

Lineage labeling with zebrafish hand2 Cre and CreERT2 recombinase CRISPR knock‐ins

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The ability to generate endogenous Cre recombinase drivers using CRISPR‐Cas9 knock‐in technology allows lineage tracing, cell type‐specific gene studies, and in vivo validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish hand2 Cre and CreERT2 drivers

Hepatoportal Leptin Sensors and Their Reflex Effects on Autonomic Outflow in the Rat

open access: yesJournal of Obesity, 2011
Afferent nerve signals were recorded from a peripheral cut end of the small nerve bundle of the hepatic branch of the vagus nerve in anesthetized rats. An injection of leptin (100 pg, 0.1 mL) into the portal vein facilitated the afferent activity.

Effects of distention of the small intestine on the movements of the gallbladder and the sphincter of Oddi [PDF]

open access: yes, 1969
1. Dogs anesthetized with pentobarbital sodium were mainly used and effects of the distention of the small intestine on the movements of the gall bladder and the sphincter of Oddi were investigated. 2.
