New insights into rodent brain microstructure and metabolism in hepatic encephalopathy

Type C hepatic encephalopathy (HE) is a severe neuropsychiatric complication of chronic liver disease, for which the prognosis is poor in the absence of liver transplantation. Cirrhosis in type C HE leads to a toxic accumulation of ammonia in the blood, wh ...

PIRACY: An Optimized Pipeline for Functional Connectivity Analysis in the Rat Brain

Rolf Gruetter, Ileana Ozana Jelescu, Ting Yin, Yujian Diao

Resting state functional MRI (rs-fMRI) is a widespread and powerful tool for investigating functional connectivity (FC) and brain disorders. However, FC analysis can be seriously affected by random and structured noise from non-neural sources, such as phys ...

A new rat model of creatine transporter deficiency reveals behavioral disorder and altered brain metabolism

Maria del Carmen Sandi Perez, Cristina Ramona Cudalbu, Jocelin Grosse, Dunja Simicic

Creatine is an organic compound used as fast phosphate energy buffer to recycle ATP, important in tissues with high energy demand such as muscle or brain. Creatine is taken from the diet or endogenously synthetized by the enzymes AGAT and GAMT, and specifi ...

Multidisciplinary Approach to Treat Erectile Dysfunction

Mikaël Nils Sturny

Erectile dysfunction (ED) is a widespread disease affecting approximately 20% of men. With a rising incidence due to the global ageing of the world population, it is estimated that over 322 million patients will be affected in 2025. While not being a lifet ...

Synchronous nonmonotonic changes in functional connectivity and white matter integrity in a rat model of sporadic Alzheimer's disease

Bernard Lanz, Carole Poitry-Yamate, Katarzyna Pierzchala, Ileana Ozana Jelescu, Ting Yin, Yujian Diao

Brain glucose hypometabolism has been singled out as an important contributor and possibly main trigger to Alzheimer's disease (AD). Intracerebroventricular injections of streptozotocin (icv-STZ) cause brain glucose hypometabolism without systemic diabetes ...

Cbp-dependent histone acetylation mediates axon regeneration induced by environmental enrichment in rodent spinal cord injury models

Grégoire Courtine, Quentin Barraud, Kay Alexander Bartholdi, Claudia Kathe, Thomas Haynes Hutson

After a spinal cord injury, axons fail to regenerate in the adult mammalian central nervous system, leading to permanent deficits in sensory and motor functions. Increasing neuronal activity after an injury using electrical stimulation or rehabilitation ca ...

Inhaling xenon ameliorates l -dopa-induced dyskinesia in experimental parkinsonism

Tomislav Milekovic, Grégoire Courtine, Eduardo Martin Moraud, Shiqi Sun

Parkinson's disease motor symptoms are treated with levodopa, but long‐term treatment leads to disabling dyskinesia. Altered synaptic transmission and maladaptive plasticity of corticostriatal glutamatergic projections play a critical role in the pathophys ...

Mesenchymal stem cell-derived extracellular vesicles ameliorate inflammation-induced preterm brain injury

Yohan Van de Looij

Objective Preterm brain injury is a major cause of disability in later life, and may result in motor, cognitive and behavioural impairment for which no treatment is currently available. The aetiology is considered as multifactorial, and one underlying key ...

IGF-1-containing multi-layered collagen-fibrin hybrid scaffolds for bladder tissue engineering

Jeffrey Alan Hubbell, Peter Frey, Priscilla Suhasna Maithili Briquez, Hans Mattias Larsson, Elif Vardar, Kalitha Pinnagoda

Clinical success of bladder reconstructive procedures could be promoted by the availability of functional biomaterials. In this study, we have developed a multi-layered scaffold consisting of a bioactive fibrin layer laminated between two collagen sheets a ...

Long Term Hippocampal and Cortical Changes Induced by Maternal Deprivation and Neonatal Leptin Treatment in Male and Female Rats

Erika Myrna Borcel Novoa

Maternal deprivation (MD) during neonatal life has diverse long-term behavioral effects and alters the development of the hippocampus and frontal cortex, with several of these effects being sexually dimorphic. MD animals show a marked reduction in their ci ...

Photobiomodulation Suppresses Alpha-Synuclein-Induced Toxicity in an AAV-Based Rat Genetic Model of Parkinson's Disease

Hubert van den Bergh, Georges Wagnières, Hilal Lashuel, Blaise Lovisa, Abid Oueslati, John Perrin

Converging lines of evidence indicate that near-infrared light treatment, also known as photobiomodulation (PBM), may exert beneficial effects and protect against cellular toxicity and degeneration in several animal models of human pathologies, including n ...

alpha-Synuclein-induced dopaminergic neurodegeneration in a rat model of Parkinson's disease occurs independent of ATP13A2 (PARK9)

Liliane Glauser, Bernard Schneider, Darren Moore, Alessandra Musso, Elpida Tsika, Aris Nikolaos Fiser, Guillaume Daniel

Mutations in the ATP13A2 (PARK9) gene cause early-onset, autosomal recessive Parkinson's disease (PD) and Kufor-Rakeb syndrome. ATP13A2 mRNA is spliced into three distinct isoforms encoding a P5-type ATPase involved in regulating heavy metal transport acro ...

Ex situ evaluation of the composition of protein corona of intravenously injected superparamagnetic nanoparticles in rats

Heinrich Hofmann, Morteza Mahmoudi, Usawadee Sakulkhu, Lionel André Maurizi, Marie-Gabrielle Chantal Brigitte Ollivier Beuzelin

It is now well recognized that the surfaces of nanoparticles (NPs) are coated with biomolecules (e. g., proteins) in a biological medium. Although extensive reports have been published on the protein corona at the surface of NPs in vitro, there are very fe ...

Involvement of autophagy in hypoxic-excitotoxic neuronal death

Nikita Rudinskiy

Neuronal autophagy is increased in numerous excitotoxic conditions including neonatal cerebral hypoxia-ischemia (HI). However, the role of this HI-induced autophagy remains unclear. To clarify this role we established an in vitro model of excitotoxicity co ...

Interaction of inflammation and hyperoxia in a rat model of neonatal white matter damage

Yohan Van de Looij

Intrauterine infection and inflammation are major reasons for preterm birth. The switch from placenta-mediated to lung-mediated oxygen supply during birth is associated with a sudden rise of tissue oxygen tension that amounts to relative hyperoxia in prete ...

Evidence for a role of oxytocin receptors in the long-term establishment of dominance hierarchies

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Marjan Timmer

Exposure to stress can affect the establishment of dominance hierarchies. In our model, a social hierarchy established by two male rats during a first encounter is not maintained 1 week later. If one of the two rats is stressed, the stressed rat becomes su ...
