Endocannabinoid LTD in Accumbal D1 Neurons Mediates Reward-Seeking Behavior
2020
Summary The nucleus accumbens (NAc) plays a key role in drug-related behavior and natural reward learning. Synaptic plasticity in dopamine D1 and D2 receptor medium spiny neurons (MSNs) of the NAc and the endogenous cannabinoid (eCB) system have been implicated in reward seeking. However, the precise molecular and physiological basis of reward-seeking behavior remains unknown. We found that the specific deletion of metabotropic glutamate receptor 5 (mGluR5) in D1-expressing MSNs (D1miRmGluR5 mice) abolishes eCB-mediated long-term depression (LTD) and prevents the expression of drug (cocaine and ethanol), natural reward (saccharin), and brain-stimulation-seeking behavior. In vivo enhancement…
The role of extracellular calcium in bone metastasis
2016
AbstractThis review summarizes the role of extracellular calcium, as found present in the bone tissue, in the process of bone metastasis.
Distinct Osteomimetic Response of Androgen-Dependent and Independent Human Prostate Cancer Cells to Mechanical Action of Fluid Flow: Prometastatic Im…
2016
BACKGROUND AND METHODS Prostate cancer frequently expresses an osteomimetic phenotype, but it is unclear how it is regulated and what biological and clinical implications it confers. Because mechanical forces physiologically regulate bone-remodeling activity in osteocytes, we hypothesized that mechanical action of fluid flow (MAFF) at the cancer microenvironment may similarly foster prostate cancer cell osteomimicry. RESULTS We showed that in vitro MAFF on androgen-dependent (LNCap) and androgen-independent (PC3) prostate cancer cells remarkably increased OPG, VEGF, RunX2, PTH1R, and PTHrP gene expression in both cell lines irrespective of their androgen dependency. MAFF also altered the cy…
Early reductive stress and late onset overexpression of antioxidant enzymes in experimental myocardial infarction.
2020
Reductive stress is defined as a pathophysiological situation in which the cell becomes more reduced than in the normal, resting state. It represents a disturbance in the redox state that is harmful to biological systems. Our aim was to study the occurrence of reductive stress in the early phases of experimental myocardial infarction and to determine the mechanisms leading to such stress using a swine model. During the ischemic period, we found a decrease in the oxidized to reduced glutathione ratio (GSSG/GSH) (0.7-0.3), in the lactate to pyruvate ratio (42.7-132.4), in protein glutathionylation (111.8-96.1), and in p38 phosphorylation (0.9-0.4). This was accompanied by a significant increa…
Detection of temporal clusters of health care-associated infections or colonizations with Pseudomonas aeruginosa.
2016
International audience; We investigated temporal clusters of Pseudomonas aeruginosa cases between 2005 and 2014 in 1 French university hospital, overall and by ward, using the Kulldorff method. Clusters of positive water samples were also investigated at the whole hospital level. Our results suggest that water outlets are not closely involved in the occurrence of clusters of P aeruginosa cases.
Administrative Coding in Electronic Health Care Record‐Based Research of NAFLD: An Expert Panel Consensus Statement
2021
BACKGROUND AND AIMS: Electronic health record (EHR)-based research allows the capture of large amounts of data, which is necessary in nonalcoholic fatty liver disease (NAFLD), where the risk of clinical liver outcomes is generally low. The lack of consensus on which International Classification of Disease (ICD) codes should be used as exposures and outcomes limits comparability and generalizability of results across studies. We aimed to establish consensus among a panel of experts on ICD codes that could become the reference standard and provide guidance around common methodological issues.APPROACH AND RESULTS: Researchers with an interest in EHR-based NAFLD research were invited to collect…
Protective Effects of Statins Administration in European and North American Patients Infected with COVID-19: A Meta-Analysis
2021
AbstractSevere acute respiratory syndrome coronavirus 2 has spread rapidly throughout the world, becoming an overwhelming global health emergency. The array of injuries caused by this virus is broad and not limited to the respiratory system, but encompassing also extensive endothelial and systemic tissue damage. Since statins effectively improve endothelial function, these drugs may have beneficial effects in patients with coronavirus disease 2019 (COVID-19). Therefore, this investigation aimed to provide an updated overview on the interplay between statins and COVID-19, with particular focus on their potentially protective role against progression toward severe or critical illness and deat…
“New Kids on the Block” — The Game Changers. The Role of Immune Check Point Blockade in Personalised Treatment of Prostate, Urinary Bladder and Kidne…
2021
Abstract Early detection and diagnosis of cancer followed by a personalised approach to treatment is a key and can save lives. It has been an important issue in both the medical and social fields. The search for instruments and/or diagnostics tools able to detect cancers at an early stage has led to consideration of the usage of various approaches, such as exhaled air, biomarkers in blood, urine testing as well as imaging techniques. This actual time and everything that is happening around us could be characterised as a strange and very unpredictable time. This comparison could be made not only due to the actual coronavirus situation, but also the same can be noticed in the personalised med…
Assessing Command-Following and Communication With Vibro-Tactile P300 Brain-Computer Interface Tools in Patients With Unresponsive Wakefulness Syndro…
2018
Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor disablities, and thus assessing their spared cognitive abilities can be difficult. Recent research from several groups has shown that non-invasive brain-computer interface (BCI) technology can provide assessments of these patients' cognitive function that can supplement information provided through conventional behavioral assessment methods. In rare cases, BCIs may provide a binary communication mechanism. Here, we present results from a vibrotactile BCI assessment aiming at detecting command-following and communication in 12 unresponsive wakefulness syndrome (UWS) patients. Two different paradigms were admi…
Factors associated with nocturia-related quality of life in men with lower urinary tract symptoms and treated with tamsulosin oral controlled absorpt…
2020
Nocturia impairs quality of life (QoL). We have performed a non-interventional study in which men with lower urinary tract symptoms (LUTS) were treated for at least 3 months with tamsulosin oral controlled absorption system (0.4 mg q.d.). Other than observing efficacy and tolerability of this drug formulation, the study was designed to explore the relative roles of number of nocturia episodes and of non-urological causes of nocturia on nocturia-related QoL at baseline and treatment-associated changes thereof. The study enrolled 5775 men seeking treatment of their LUTS. Tamsulosin improved LUTS, e.g. International Prostate Symptom Score from 19.5 +/- 5.9 to 10.1 +/- 4.9 (means +/- SD). This …
