Abstract
DCMU [N-(3,4-dichlorophenyl)-N-dimethylurea] or diuron is a widely used herbicide, which can cause adverse effects on human, especially on immune cells, due to their intrinsic properties and wide distribution. These cells are important for fighting not only against virus or bacteria but also against neoplastic cell development. We developed an approach that combines functional studies and miRNA and RNA sequencing data to evaluate the effects of DCMU on the human immune response against cancer, particularly the one carried out by CD8+ T cells. We found that DCMU modulates the expression of miRNA in a dose-dependent manner, leading to a specific pattern of gene expression and consequently to a diminished cytokine and granzyme B secretions. Using mimics or anti-miRs, we identified several miRNA, such as hsa-miR-3135b and hsa-miR-21-5p, that regulate these secretions. All these changes reduce the CD8+ T cells’ cytotoxic activity directed against cancer cells, in vitro and in vivo in a zebrafish model. To conclude, our study suggests that DCMU reduces T-cell abilities, participating thus to the establishment of an environment conducive to cancer development.

Abstract
BACKGROUND The impact of Minority Stress (MS) upon suicidal ideation and behaviours amongst Transgender and Gender Non-Conforming (TGNC) adults is not sufficiently understood, hence our intervention efforts on an individual and societal level are limited. This review aims to evaluate recent literature that reports on the association between MS and suicidal ideation and behaviours amongst TGNC adults. METHODS PsycINFO, Web of Science, MEDLINE, CINAHL and EMBASE were systematically searched for relevant articles. Peer reviewed and grey literature were considered. Included papers reported quantitative analyses on associations between MS factors and suicidal ideation and behaviours amongst TGNC adults. The quality of papers was assessed. RESULTS 28 papers were identified as eligible. Findings suggested positive associations between external and internal minority stressors and suicidal ideation and behaviour. Dysfunctional individual coping was associated with a greater likelihood of suicide attempts. Community resilience was negatively associated with suicidal outcomes, but did not consistently buffer the effects of minority stress. LIMITATIONS Overall quality of included papers was 'poor'. Almost all papers were cross-sectional by design, therefore causality cannot be inferred. Many papers measured variables using non-standardised measures undermining the reliability and validity of reported results. CONCLUSIONS Findings offer support to the application of MS theory to the understanding of suicidal ideation and behaviour amongst TGNC. Future research should use standardised measures and longitudinal designs to better support the investigation of directionality and causality. More research is needed to understand the complex interactions between minority stress factors and the role of resilience in this population.

Abstract
Neuro-anatomical evidence supports the potential for threat-related factors, such as fear, anxiety and vigilance, to influence brainstem motor nuclei controlling eye movements, as well as the vestibular nuclei. However, little is known about how threat influences human ocular responses, such as eye saccades (ES), smooth pursuit eye tracking (SP), and optokinetic nystagmus (OKN), and whether these responses can be facilitated above normal baseline levels with a natural source of threat. This study was designed to examine the effects of height-induced postural threat on the gain of ES, SP and OKN responses in humans. Twenty participants stood at two different surface heights while performing ES (ranging from 8° to 45° from center), SP (15, 20, 30°/s) and OKN (15, 30, 60°/s) responses in the horizontal plane. Height did not significantly increase the slope of the relationship between ES peak velocity and initial amplitude, or the gain of ES amplitude. In contrast height significantly increased SP and OKN gain. Significant correlations were found between changes in physiological arousal and OKN gain. Observations of changes with height in OKN and SP support neuro-anatomical evidence of threat-related mechanisms influencing both oculo-motor nuclei and vestibular reflex pathways. Although further study is warranted, the findings suggest that potential influences of fear, anxiety and arousal/alertness should be accounted for, or controlled, during clinical vestibular and oculo-motor testing.

Abstract
We investigated how vestibulo-spinal reflexes (VSRs) and vestibulo-ocular reflexes (VORs) measured through vestibular evoked myogenic potentials (VEMPs) and video head impulse test (vHIT) outcomes, respectively, are modulated during standing under conditions of increased postural threat. Twenty-five healthy young adults stood quietly at low (0.8 m from the ground) and high (3.2 m) surface height conditions in two experiments. For the first experiment (n = 25) VEMPs were recorded with surface EMG from inferior oblique (IO), sternocleidomastoid (SCM), trapezius (TRP), and soleus (SOL) muscles in response to 256 air-conducted short tone bursts (125 dB SPL, 500 Hz, 4 ms) delivered via headphones. A subset of subjects (n = 19) also received horizontal and vertical head thrusts (∼150°/s) at each height in a separate session, comparing eye and head velocities by using a vHIT system for calculating the functional VOR gains. VEMP amplitudes (IO, TRP, SOL) and horizontal and vertical vHIT gains all increased with high surface height conditions (P < 0.05). Changes in IO and SCM VEMP amplitudes as well as horizontal vHIT gains were correlated with changes in electrodermal activity (ρ = 0.44-0.59, P < 0.05). VEMP amplitude for the IO also positively correlated with fear (ρ = 0.43, P = 0.03). Threat-induced anxiety, fear, and arousal have significant effects on VSR and VOR gains that can be observed in both physiological and functional outcome measures. These findings provide support for a potential central modulation of the vestibular nucleus complex through excitatory inputs from neural centers involved in processing fear, anxiety, arousal, and vigilance.

Abstract
AIM The purpose of this investigation was to determine the effects of 3 d of creatine supplementation on thermoregulation and isokinetic muscular performance. METHODS Fourteen males performed two exercise bouts following 3 d of creatine supplementation and placebo. Subjects exercised for 60 min at 60-65% of VO2max in the heat followed by isokinetic muscular performance at 60, 180, and 300°·s(-1). Dependent variables for pre- and postexercise included nude body weight, urine specific gravity, and serum creatinine levels. Total body water, extracellular water and intracellular water were measured pre-exercise. Core temperature was assessed every 5 min during exercise. Peak torque and Fatigue Index were used to assess isokinetic muscular performance. RESULTS Core temperature increased during the run for both conditions. Total body water and extracellular water were significantly greater (P<0.05) following creatine supplementation. No significant difference (P>0.05) was found between conditions for intracellular water, nude body weight, urine specific gravity, and serum creatinine. Pre-exercise scores for urine specific gravity and serum creatinine were significantly less (P<0.05) versus post-exercise. No significant differences (P>0.05) were found in peak torque values or Fatigue Index between conditions for each velocity. A significant (P<0.05) overall velocity effect was found for both flexion and extension. As velocity increased, mean peak torque values decreased. CONCLUSION Three d of creatine supplementation does not affect thermoregulation during submaximal exercise in the heat and is not enough to elicit an ergogenic effect for isokinetic muscle performance following endurance activity.

Abstract
BACKGROUND Flow cytometric immunophenotpying (FCI) of cerebrospinal fluid (CSF) and other paucicellular fluids has been demonstrated to have increased sensitivity in detection of lymphoma and leukemia when compared to cytomorphology [(1) de Graaf et al., Cytometry Part B 2011, 80B:271-281; (2) Szamosi et al., CLSI Document H56-A-Body Fluid Analysis for Cellular Composition; Approved Guideline, Wayne, PA: Clinical and Laboratory Standards Institute, 2006; (3) Kraan et al., Flow Cytometric Immunophenotyping of Cerebrospinal Fluid. Current Protocols in Cytometry, Hoboken, NJ: Wiley, 2008]. However, low cellularity has been an historical problem with these samples. Several studies indicate that immediate addition of a stabilization media (e.g., RPMI with fetal calf serum (FCS)) to CSF improves the cell yield for FCI [(1) de Graaf et al.]. Such stabilization medias can, however, significantly increase cost. METHODS We compared FCI results in CSF stabilized with RPMI 1640 (without additional additives) to results obtained using non-stabilized CSF. Samples were processed according to published CLSI guidelines [(2) Szamosi et al.]. RESULTS About 98/105 (93%) CSF specimens stabilized with RPMI had adequate numbers of viable cells (>100) for performing FCI. About 65/217 (30%) CSF specimens without stabilization had adequate numbers of viable cells for analysis (70% either quantity not sufficient (QNS) or specimen viability below analytical limits). CONCLUSIONS Utilizing RMPI without FCS as a stabilization media results in increased cell yield and improved FCI results. We have found FCS is not required to achieve high quality results in FCI of paucicellular CSF specimens.
