Hypothalamic dysfunction is a key factor in depression; increasing evidence highlights neuroinflammation abnormalities as well as imbalances in neurotransmitters and the purinergic system in the pathophysiology of depression. However, little is known about the metabolomic changes in the hypothalamus of depressed patients with neuroinflammation. Herein, taking advantage of the well-established lipopolysaccharide (LPS)-induced depression mouse model, we measured metabolic changes in the hypothalamus using gas chromatography-mass spectrometry (GC-MS)...

Kai Zhang, Chao Dong, Yuko Fujita, Atsuhiro Fujita, Kenji Hashimoto
Background: Previous reports suggest that 5-hydroxytryptamine (5-HT) might play a role in the antidepressant actions of (R,S)-ketamine. However, its role in the antidepressant actions of (R)-ketamine, which is more potent than (S)-ketamine, is unknown. This study was conducted to examine whether 5-HT depletion affects the antidepressant actions of (R)-ketamine in a chronic social defeat stress (CSDS) model. Methods: An inhibitor of 5-HT synthesis, para-chlorophenylalanine methyl ester hydrochloride (PCPA; 300 mg/kg, twice daily for 3 consecutive days), or vehicle was administered to control and CSDS susceptible mice...

REVIEW
Hallie C Prescott, Deena Kelly Costa
Although acute survival from sepsis has improved in recent years, a large fraction of sepsis survivors experience poor long-term outcomes. In particular, sepsis survivors have high rates of weakness, cognitive impairment, hospital readmission, and late death. To improve long-term outcomes, in-hospital care should focus on early, effective treatment of sepsis; minimization of delirium, distress, and immobility; and preparing patients for hospital discharge. In the posthospital setting, medical care should focus on addressing new disability and preventing medical deterioration, providing a sustained period out of the hospital to allow for recovery...

Recent findings suggest that altered rest-activity circadian rhythms (RARs) are associated with a compromised health status. RARs abnormalities have been observed also in several pathological conditions, such as cardiovascular, neurological, and cancer diseases. Binge eating disorder (BED) is the most common eating disorder, with a prevalence of 3.5% in women and 2% in men. BED and its associate obesity and motor inactivity could induce RARs disruption and have negative consequences on health-related quality of life...

The MPTA (mesopontine tegmental anesthesia area) is a key node in a network of axonal pathways that collectively engage the key components of general anesthesia: immobility and atonia, analgesia, amnesia and loss-of-consciousness. In this study we have applied double retrograde tracing to analyze MPTA connectivity, with a focus on axon collateralization. Prior tracer studies have shown that collectively, MPTA neurons send descending projections to spinal and medullary brain targets associated with atonia and analgesia as well as ascending projections to forebrain structures associated with amnesia and arousal...

Peripheral immune activation can have profound physiologic and behavioral effects. One mechanism through which immune activation may affect physiology and behavior is through actions on brainstem neuromodulatory systems, such as serotonergic systems. To test this hypothesis, in Experiment 1, adult male BALB/c mice were implanted with telemetric recording devices and then immunized with Mycobacterium vaccae NCTC 11659 (0.1 mg, s.c.; Days - 28, - 14; N = 36). On Day 1, mice received an acute challenge with M...

Metabolic and behavioural effects of, and interactions between Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) are influenced by dose and administration route. Therefore we investigated, in Wistar rats, effects of pulmonary, oral and subcutaneous (sc.) THC, CBD and THC+CBD. Concentrations of THC, its metabolites 11-OH-THC and THC-COOH, and CBD in serum and brain were determined over 24h, locomotor activity (open field) and sensorimotor gating (prepulse inhibition, PPI) were also evaluated. In line with recent knowledge we expected metabolic and behavioural interactions between THC and CBD...

We analyzed parameters of parasitism by helminths in a pair of sympatric congeneric lizard species (Tropidurus hispidus and Tropidurus semitaeniatus). Differences in their supracommunities (richness, composition, and abundance) and the influence of helminthic loads on minimum flight initiation distances and body temperatures were evaluated. We reported new findings of Piratuba digiticauda infecting T. hispidus and Oochoristica bresslaui infecting T. semitaeniatus. Parapharyngodon alvarengai was the most abundant helminth in both host species...

BACKGROUND: Ursolic acid has been shown to display antidepressant-like effects in mice through the modulation of monoaminergic systems. In this study, we sought to investigate the involvement of signaling pathways on the antidepressant-like effects of ursolic acid. METHODS: Mice were treated orally with ursolic acid (0.1mg/kg) and, 45min later they received the followings inhibitors by intracerebroventricular route: H-89 (PKA inhibitor, 1μg/mouse), KN-62 (CAMK-II inhibitor, 1μg/mouse), chelerythrine (PKC inhibitor, 1μg/mouse), U0126 (MEK1/2 inhibitor, 5μg/mouse), PD98059 (MEK1/2 inhibitor, 5μg/mouse), wortmannin (PI3K irreversible inhibitor, 0...

Plants are used as representative reference biota for the biological assessment of environmental risks such as ionizing radiation due to their immobility. This study proposed a faster, more economical, and more effective method than conventional cytogenetic methods for the biological dosimetry of ionizing radiation in plants (phytodosimetry). We compared various dose-response curves for the radiation-induced DNA damage response (DDR) in Arabidopsis thaliana after relatively "low-dose" gamma irradiation (3, 6, 12, 24, and 48 Gy) below tens of Gy using comet (or single-cell gel electrophoresis), gamma-H2AX, and transcriptomic assays of seven DDR genes (AGO2, BRCA1, GRG, PARP1, RAD17, RAD51, and RPA1E) using quantitative real time PCR...

One problem area regarding animal models for affective disorders is unclear reproducibility, including external validity or generalizability. One way to evaluate external validity is with systematic reviews and meta-analyses. The current study presents a meta-analysis of the effects of prototypic antidepressants in the mouse forced swim test (FST). We identified studies that examined effects of antidepressants in the FST in mice and used standard protocol, male mice and acute drug administration. We calculated Effect sizes using Cohen's d, homogeneity using Q statistic and correlations using Pearson's correlation...

Adverse early life experiences can affect adaptability to chronic stressors and lead to depressive-like behaviors in animal models. We employed an early experience model in which rat pups during postnatal days 10-13 are exposed to a T-maze in which they learn the location of their mother motivated by the rewarding stimulus of maternal contact; one group of rats receives the expected reward, by being allowed contact with the mother upon finding her, while the other group is temporarily denied this contact (Denied Expected Reward, DER), thus experiencing mild adversity...

BACKGROUND: Difficulty turning over in bed is a common night-time symptom in Parkinson's disease (PD). We aimed to quantitatively evaluate overnight turnover movements using a three-axis accelerometer and to investigate whether inability to turn in bed is related to daytime sleepiness, sleep quality, and depressive mood in PD patients. METHODS: We examined 64 patients with PD (mean age, 73.3±8.21 years; modified Hoehn-Yahr [mH-Y] stage, 3.0±1.0; disease duration, 7...

Lithium carbonate is considered an effective drug against mania and acts as a mood stabilizer. It is found that it enhances antidepressants targeting depression, consequently it is prone to have risk factors that leads to adverse effects. The study is devised in confronting depression under nanoscale by preparing nanocomposites which is a matrix of biopolymer chitosan that encapsulates lithium carbonate by ionic gelation method. This facilitates the drug delivery in a regulated manner targeting the therapeutic action with a limited dosage that lessens the side effects in the course of treatment...

Improved identification of children with an increased likelihood of death can support appropriate provision of integrated palliative care. This systematic review aims to consider immobility and the associated likelihood of death in children with disabilities, living in high-income countries. Two reviewers independently searched MEDLINE, Embase, Cochrane Library, OpenGrey and Science Citation Index (1990-2016) for studies that reported hazard ratios (HRs) and relative risk for the likelihood of death related to impaired mobility...

Catatonia is a clinical syndrome characterized by symptoms such as immobility, mutism, stupor, stereotypy, echophenomena, catalepsy, automatic obedience, posturing, negativism, gegenhalten and ambitendency. This syndrome occurs mostly in mood disorder and schizophrenic patients, and is related to neuronal dysfunction involving the frontal lobe. Some cases of frontotemporal dementia (FTD) with catatonia have been reported, but these cases were not examined by autopsy. Here, we report on a FTD case which showed catatonia after the first episode of brief psychotic disorder...
