Temporal dynamics of intranasal oxytocin in human brain electrophysiology

Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Oxytocin (OT) is a key modulator of human social cognition, popular in behavioral neuroscience. To adequately design and interpret intranasal OT (IN-OT) research, it is crucial to know for how long it affects human brain function once administered. However ...

A tool for mapping microglial morphology, morphOMICs, reveals brain-region and sex-dependent phenotypes

Kathryn Hess Bellwald, Lida Kanari, Martina Scolamiero

Environmental cues influence the highly dynamic morphology of microglia. Strategies to characterize these changes usually involve user-selected morphometric features, which preclude the identification of a spectrum of context-dependent morphological phenot ...

Signatures of life course socioeconomic conditions in brain anatomy

Maria del Carmen Sandi Perez

Socioeconomic status (SES) plays a significant role in health and disease. At the same time, early-life conditions affect neural function and structure, suggesting the brain may be a conduit for the biological embedding of SES. Here, we investigate the bra ...

Simulating the progression of brain structural alterations in Parkinson's disease

Chang-Hyun Park

Considering brain structural alterations as neurodegenerative consequences of Parkinson's disease (PD), we sought to infer the progression of PD via the ordering of brain structural alterations from cross-sectional MRI observations. Having measured cortica ...

Axonal and Dendritic Morphology of Excitatory Neurons in Layer 2/3 Mouse Barrel Cortex Imaged Through Whole-Brain Two-Photon Tomography and Registered to a Digital Brain Atlas

Carl Petersen, Sylvain Crochet, Georgios Foustoukos, Yanqi Liu

Communication between cortical areas contributes importantly to sensory perception and cognition. On the millisecond time scale, information is signaled from one brain area to another by action potentials propagating across long-range axonal arborizations. ...

Magnitude of gluconeogenesis and endogenous glucose production: are they predictable in clinical settings?

Marc Anthony David Habisreutinger

Introduction: Regulation of endogenous glucose production (EGP) is essential for glucose homeostasis. It includes gluconeogenesis (GNG) from non-carbohydrate substrates and hepatic glycogenolysis. Both these pathways are dysregulated in acute stress, but t ...

A Machine-Generated View of the Role of Blood Glucose Levels in the Severity of COVID-19

Henry Markram, Daniel Keller, Emmanuelle Logette, Francesco Casalegno, Jay Coggan, Cyrille Pierre Henri Favreau, Mohameth François Sy, Samuel Claude Kerrien, Anna-Kristin Kaufmann, Pierre-Alexandre Fonta, Enrico Scantamburlo, Charlotte Lorin, Marine Laure Bertschy, Jan Krepl, Emilie Delattre, Stanislav Schmidt, Caitlin Claire Monney

SARS-CoV-2 started spreading toward the end of 2019 causing COVID-19, a disease that reached pandemic proportions among the human population within months. The reasons for the spectrum of differences in the severity of the disease across the population, an ...

Very Selective Detection of Low Physiopathological Glucose Levels by Spontaneous Raman Spectroscopy with Univariate Data Analysis

Christian Enz, Sandro Carrara, Assim Boukhayma, Antonino Caizzone, Ata Jedari Golparvar

After decades of research on non-invasive glucose monitoring, invasive devices based on finger blood sampling are still the predominant reference for diabetic patients for accurately measuring blood glucose levels. Meanwhile, research continues improving p ...

Measuring Glycolytic Activity with Hyperpolarized [2H7, U-13C6] D-Glucose in the Naive Mouse Brain under Different Anesthetic Conditions

Yves Pilloud, Bernard Lanz, Rolf Gruetter, Mor-Miri Mishkovsky, Emmanuelle Ines Flatt, Andrea Capozzi

Glucose is the primary fuel for the brain; its metabolism is linked with cerebral function. Different magnetic resonance spectroscopy (MRS) techniques are available to assess glucose metabolism, providing complementary information. Our first aim was to inv ...

Assessment of Aspartate and Bicarbonate Produced From Hyperpolarized [1-13C]Pyruvate as Markers of Renal Gluconeogenesis

Arnaud Comment, Hikari Ananda Infinity Yoshihara

As both a consumer and producer of glucose, the kidney plays a significant role in glucose homeostasis. Measuring renal gluconeogenesis requires invasive techniques, and less invasive methods would allow renal gluconeogenesis to be measured more routinely. ...

Co-regulation of endothelial and myogenic cell fates through intercellular crosstalk in skeletal muscle

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...

Investigation of the specificity and mechanism of action of the ULK1/AMPK inhibitor SBI-0206965

Katyayanee Neopane

SBI-0206965, originally identified as an inhibitor of the autophagy initiator kinase ULK1, has recently been reported as a more potent and selective AMP-activated protein kinase (AMPK) inhibitor relative to the widely used, but promiscuous inhibitor Compou ...
