Structural and Functional Imaging of Pancreatic Islets using Optical Coherence Microscopy

In diabetes, pancreatic beta-cells play a key role. These cells are organized within structures called islets of Langerhans inside the pancreas and produce insulin. Insulin is one of the main hormones contributing to glucose homeostasis, which is the hallm ...

Effect of manganese chloride on the neurochemical profile of the rat hypothalamus

Rolf Gruetter, Cristina Ramona Cudalbu, Nathalie Just, Hongxia Lei

Manganese (Mn 2+)-enhanced magnetic resonance imaging studies of the neuronal pathways of the hypothalamus showed that information about the regulation of food intake and energy balance circulate through specific hypothalamic nuclei. The dehydration-induce ...

Perinatal Exposure to Bisphenol A Increases Adult Mammary Gland Progesterone Response and Cell Number

Cathrin Brisken, Jacques Rougemont, Ayyakkannu Ayyanan, Tamara Tanos, Christina Schrick

Bisphenol A [BPA, 2,2,-bis (hydroxyphenyl) propane] is one of the highest-volume chemicals produced worldwide. It is detected in body fluids of more than 90% of the human population. Originally synthesized as an estrogenic compound, it is currently utilize ...

Neurochemical profile of the mouse hypothalamus using in vivo1H MRS at 14.1T

Rolf Gruetter, Hongxia Lei, Carole Poitry-Yamate

The hypothalamus plays an essential role in the central nervous system of mammals by among others regulating glucose homeostasis, food intake, temperature, and to some extent blood pressure. Assessments of hypothalamic metabolism using, e.g. 1H MRS in mous ...

The rate-limiting step for glucose transport into the hypothalamus is across the blood–hypothalamus interface

Rolf Gruetter, Hongxia Lei, Carole Poitry-Yamate

Specialized glucosensing neurons are present in the hypothalamus, some of which neighbor the median eminence, where the blood–brain barrier has been reported leaky. A leaky blood–brain barrier implies high tissue glucose levels and obviates a role for endo ...
