Objective: Equine-assisted activities and therapy (EAA/T) have been used as adjunct treatment options for physical and psychosocial rehabilitation. However, the therapeutic effects on resting-state brain function have not yet been studied. The aim of this study is to investigate the effects of EAA/T on participants with attention-deficit/hyperactivity disorder (ADHD) by comparing resting-state functional magnetic resonance imaging (rs-fMRI) signals and their clinical correlates. Methods: Ten participants with ADHD participated in a 12-week EAA/T program without any medication...

There is no consensus as to whether drainage tube should be used and how long it should remain in use after primary total knee arthroplasty (TKA). As fast-track (FT) program has been implemented in TKA, whether drainage tube could be removed early, and the ideal timing for removal after FT primary TKA has been a new topic. The purpose of this prospective cohort study was to evaluate the safety and feasibility of early removal of drainage tube when FT program was implemented in primary TKA. A total of 101 patients undergoing FT primary TKA were prospectively allocated into three groups...

BACKGROUND: Physical activity (PA) has beneficial, whereas exposure to traffic related air pollution (TRAP) has adverse, respiratory effects. Few studies, however, have examined if the acute effects of TRAP upon respiratory outcomes are modified depending on the level of PA. OBJECTIVES: The aim of our study was to disentangle acute effects of TRAP and PA upon respiratory outcomes and assess the impact of participants TRAP pre-exposure. METHODS: We conducted a real-world crossover study with repeated measures of 30 healthy adults...

OBJECTIVE: We hypothesized that compared to healthy controls, long-term abstinent substance dependent individuals (SDI) will differ in their effective connectivity between large-scale brain networks and demonstrate increased directional information from executive control to interoception-, reward-, and habit-related networks. In addition, using graph theory to compare network efficiencies we predicted decreased small-worldness in SDI compared to controls. METHODS: 50 SDI and 50 controls of similar sex and age completed psychological surveys and resting state fMRI...

Microglia are the resident macrophages of the central nervous system (CNS). Gene expression profiling has identified Sall1, which encodes a transcriptional regulator, as a microglial signature gene. We found that Sall1 was expressed by microglia but not by other members of the mononuclear phagocyte system or by other CNS-resident cells. Using Sall1 for microglia-specific gene targeting, we found that the cytokine receptor CSF1R was involved in the maintenance of adult microglia and that the receptor for the cytokine TGF-β suppressed activation of microglia...

Fetal motility is a widely accepted indicator of the well-being of a fetus. In previous research, it has be shown that fetal motion (FM) is coherent with fetal heart rate accelerations and an indicator for active/rest cycles of the fetus. The most common approach for FM and fetal heart rate (FHR) assessment is by Doppler ultrasound (DUS). While DUS is the most common approach for studying the mechanical activities of the heart, noninvasive fetal electrocardiogram (ECG) and magnetocardiogram (MCG) recording and processing techniques have been considered as a possible competitor (or complement) for the DUS...

: The importance of functional brain connectivity to study physiological and pathological brain activity has been widely recognized. Here, we aimed to 1) review a methodological pipeline to investigate directed functional connectivity between brain regions using source signals derived from high-density EEG; 2) elaborate on some methodological challenges; 3) apply this pipeline to temporal lobe epilepsy (TLE) patients and healthy controls to investigate directed functional connectivity differences in the theta and beta frequency bands during EEG epochs without visible pathological activity...

Transcranial magnetic stimulation (TMS) can be used as an assessment or intervention to evaluate or influence brain activity in children with hemiparetic cerebral palsy (CP) commonly caused by perinatal stroke. This communication report analyzed data from two clinical trials using TMS to assess corticospinal excitability in children and young adults with hemiparetic CP. The results of this communication revealed a higher probability of finding a motor evoked potential (MEP) on the non-lesioned hemisphere compared to the lesioned hemisphere (p = 0...

Stress is considered a risk factor associated with the development of various civilization diseases including cardiovascular diseases, malignant tumors and mental disorders. Research investigating mechanisms involved in stress-induced hypertension have attracted much attention of physicians and researchers, however, there are still ambiguous results concerning a causal relationship between stress and long-term elevation of blood pressure (BP). Several studies have observed that mechanisms involved in the development of stress-induced hypertension include increased activity of sympathetic nervous system (SNS), glucocorticoid (GC) overload and altered endothelial function including decreased nitric oxide (NO) bioavailability...

Objective: Disturbances in functional connectivity have been suggested to contribute to cognitive and emotion processing deficits observed in bipolar disorder (BD). Functional connectivity between medial prefrontal cortex (mPFC) and other brain regions may be particularly abnormal. The goal of the present study was to characterize the temporal dynamics of the default mode network (DMN) connectivity in BD and examine its association with cognition. Method: In a preliminary study, euthymic BD (n = 15) and healthy comparison (HC, n = 19) participants underwent resting-state functional MRI, using high-resolution sequences adapted from the Human Connectome Project, and completed neuropsychological measures of processing speed and executive function...

INTRODUCTION: Stump appendicitis is the remaining appendicular tissue inflammation after a variable length of time. It is a very infrequent pathology with a paucity in pediatric publications, and given the fact that a delay in its diagnosis could lead to an increased morbidity, this is the reason of its clinical relevance. CLINICAL CASE: A 10 years old girl who had laparoscopic excision of a flemonous-gangrenous appendicitis and who 45 days after surgery showed new clinical symptoms compatible with a diagnosis of acute appendicitis...

BACKGROUND: As interventions have expanded beyond clinical treatment to include brief interventions for persons with less severe alcohol problems, predicting who can achieve stable moderation drinking has gained importance. Recent behavioral economic (BE) research on natural recovery has shown that active problem drinkers who allocate their monetary expenditures on alcohol and saving for the future over longer time horizons tend to have better subsequent recovery outcomes, including maintenance of stable moderation drinking...

What I uttered in Athens moved with apparent emotion [that seem to have not escaped Jules Angst's concern] was spontaneous, except for what is printed in the program book, which has somehow vanished from my office, unlike him with his larger than life figure whose memory will live for as long as he lives in the minds and hearts of all those who were privileged to be his family, colleagues, patients, friends, and… countless others, plus those whose email addresses I cannot locate right now sitting in the sunshine of La Jolla-far away from my loved ones-and wondering what ethnic, genetic and environmental factors-perhaps even several Greek gods combined-to produce the original mind and heart of our Athenian friend who, nonetheless, lived in Rome-and now resting not in the 'atheist' cemetery [it took me 5 minutes to spell this word]-but in our hearts for as long as they will beat-perhaps eventually in another realm, 'from whose bourn'-according to Hamlet-no one has ever returned-that's the promise of the Eternal City-where Athanasios is lying...

This study tested the relation between cortical-subcortical functional connectivity and alcohol consumption in adolescents using an accelerated longitudinal design, as well as normative developmental patterns for these measures. Participants between ages 8 and 27 completed resting-state neuroimaging scans at two time points separated by two years (N = 274 at T1, N = 231 at T2). In addition, participants between ages 12 and 27 reported on recent and lifetime alcohol use (N = 193 at T1, N = 244 at T2)...

Impaired cognitive empathy is a core social cognitive deficit in schizophrenia associated with negative symptoms and social functioning. Cognitive empathy and negative symptoms have also been linked to medial prefrontal and temporal brain networks. While shared behavioral and neural underpinnings are suspected for cognitive empathy and negative symptoms, research is needed to test these hypotheses. In two studies, we evaluated whether resting-state functional connectivity between data-driven networks, or components (referred to as, inter-component connectivity), predicted cognitive empathy and experiential and expressive negative symptoms in schizophrenia subjects...

The default mode network (DMN) has been identified reliably during rest, as well as during the performance of tasks such as episodic retrieval and future imagining. It remains unclear why this network is engaged across these seemingly distinct conditions, though many hypotheses have been proposed to account for these effects. Prior to generating hypotheses explaining common DMN involvement, the degree of commonality in the DMN across these conditions, within individuals, must be statistically determined to test whether or not the DMN is truly a unitary network, equally engaged across rest, retrieval and future imagining...

OBJECTIVES: Propolis is a natural product with a complex chemical composition. Its isolated compounds exert biological activities; however, its synergistic effects are unknown. The involvement of phenolic acids (caffeic - Caf, dihydrocinnamic - Cin and p-coumaric - Cou) alone or in combination was investigated in the action of propolis in human monocytes. METHODS: Cell viability was analysed by MTT assay; TNF-α, IL-6 and IL-10 production by enzyme-linked immunosorbent assay (ELISA); cell markers expression by flow cytometry; colony-forming units were counted to assess the microbicidal activity; and H2 O2 production was analysed by colorimetric assay...

PURPOSE: Anesthesia is a major confounding factor in functional MRI (fMRI) experiments attributed to its effects on brain function. Recent evidence suggests that parameters obtained with resting-state fMRI (rs-fMRI) are coupled with anesthetic depth. Therefore, we investigated whether parameters obtained with rs-fMRI, such as functional connectivity (FC), are also directly related to blood-oxygen-level-dependent (BOLD) responses. METHODS: A simple rs-fMRI protocol was implemented in a pharmacological fMRI study to evaluate the coupling between hemodynamic responses and FC under five anesthetics (α-chloralose, isoflurane, medetomidine, thiobutabarbital, and urethane)...
