title: Supplementary Material for: Self-Perceived Stigmatization in Female Patients with Anorexia Nervosa - Results from an Explorative Retrospective Pilot Study of Adolescents

description: <b><i>Background:</i></b> The stigma of mental illness has been identified as an important barrier to treatment and recovery. Previous research reported the stigmatization of individuals with eating disorders by both health professionals and the general public. The aim of this pilot study was to empirically assess the previous stigmatization and discrimination experiences of young female patients with anorexia nervosa (AN) using a retrospective explorative approach. <b><i>Methods:</i></b> An in-house questionnaire that was developed to survey experiences of stigmatization was mailed to 75 former adolescent patients with AN. The mean time of assessment after discharge was 5.6 ± 1.2 years. The patients were asked to respond anonymously. The response rate was approximately 48% (n = 36). <b><i>Results:</i></b> Feelings that society held negative stereotypes of individuals with AN, concrete experiences of stigmatization and discrimination, and rejection by peers were reported. A remarkable degree of self-stigmatization, as indexed by high rates of agreement to stigmatizing statements, was detected. Approximately one third of the participants reported delayed initiation of treatment due to fear of stigmatization and discrimination. <b><i>Conclusion:</i></b> Stigmatization plays a decisive role in young patients with AN and impacts their motivation to seek professional help and engage in treatment. Clinicians should be aware of the stigmatization related to eating disorders and its burden for affected patients.

title: Raw data files from Sink limited container volume experiment

description: This folder consists of existing dataset from the container volume experiment which was carried out at the Hawkesbury Forest Experiment site (33°37'S 150°44'E) in Richmond, NSW, Australia. The site and experimental setup have been explained in detail by Campany et al. (2017). <br>In brief, 20 weeks old Eucalyptus tereticornis seedlings in tube stock were chosen from a single local Cumberland plain cohort. Ten additional seedlings of similar age and growth were harvested to measure initial leaf area and dry mass of leaves, stems and roots. A total of 49 Eucalyptus tereticornis seedlings were grown in a range of container sizes (5 L to 35 L) in field conditions, using freely-rooted seedlings as a control for the container size treatments, with the goal to examine how the C balance of the plants are affected to belowground sink limitations. Six container sizes were used with each container experiment had a complete replicate set of six container volumes along with a free seedling. Similar notations are used here as Campany et al. (2017) for the treatments in different pots as 5 L, 10 L, 15 L, 20 L, 25 L and 35 L in respect of their pot sizes. The experiment tracked leaf-level gas exchange, leaf carbohydrate accumulation and seedling allometry over the course of 4 months for all 7 treatments.

title: Supplementary Material for: HIV-1 Nef Interacts with HCV Core, Recruits TRAF2, TRAF5 and TRAF6, and Stimulates HIV-1 Replication in Macrophages

description: Tumor necrosis factor receptor-associated factor (TRAF) signaling plays a central role in many biological activities, such as the regulation of immune and inflammatory responses and control of apoptosis, which are key events in the pathogenesis of the human immunodeficiency virus (HIV)-1 and the hepatitis C virus (HCV) infections. Here we show that TRAF2, TRAF5 and TRAF6 interact with the HIV-1 Nef protein, an immunomodulatory viral protein expressed and released by cells infected by the virus. We also found that TRAF2 and TRAF5 interact with the HCV Core protein. Interestingly, we observed that HIV-1 Nef interacts with HCV Core. The activation of TRAF (2, 5, 6) - mediated by HIV-1 Nef and HCV Core - enhanced the activation of the nuclear factor-kappa B (NF-κB) and increased HIV-1 replication in monocyte- derived macrophages (MDMs). The knockdown of TRAF2, TRAF5 and TRAF6 resulted in decreased NF-κB activation and reduced HIV-1 replication in MDMs. Our results reveal a mechanism by which the activation of the TRAF pathway by HIV-1 Nef and HCV Core favors the replication of HIV-1 in macrophages and could be a critical factor for optimal replication of HIV-1 in macrophages of HIV-HCV-coinfected patients.

title: Supplementary Material for: Nox4-Generated Superoxide Drives Angiotensin II-Induced Neural Stem Cell Proliferation

description: Reactive oxygen species (ROS) have been reported to affect neural stem cell self-renewal and therefore may be important for normal development and may influence neurodegenerative processes when ROS activity is elevated. To determine if increasing production of superoxide, via activation of NADPH oxidase (Nox), increases neural stem cell proliferation, 100 nM angiotensin II (Ang II) - a strong stimulator of Nox - was applied to cultures of a murine neural stem cell line, C17.2. Twelve hours following a single treatment with Ang II, there was a doubling of the number of neural stem cells. This increase in neural stem cell numbers was preceded by a gradual elevation of superoxide levels (detected by dihydroethidium fluorescence) from the steady state at 0, 5, and 30 min and gradually increasing from 1 h to the maximum at 12 h, and returning to baseline at 24 h. Ang II-dependent proliferation was blocked by the antioxidant N-acetyl-L-cysteine. Confocal microscopy revealed the presence of two sources of intracellular ROS in C17.2 cells: (i) mitochondrial and (ii) extramitochondrial; the latter indicative of the involvement of one or more specific isoforms of Nox. Of the Nox family, mRNA expression for one member, Nox4, is abundant in neural stem cell cultures, and Ang II treatment resulted in elevation of the relative levels of Nox4 protein. SiRNA targeting of Nox4 mRNA reduced both the constitutive and Ang II-induced Nox4 protein levels and attenuated Ang II-driven increases in superoxide levels and stem cell proliferation. Our findings are consistent with our hypothesis that Ang II-induced proliferation of neural stem cells occurs via Nox4-generated superoxide, suggesting that an Ang II/Nox4 axis is an important regulator of neural stem cell self-renewal and as such may fine-tune normal, stress- or disease-modifying neurogenesis.

title: Supplementary Material for: Do Psychosis Patients with Poor Insight Show Implicit Awareness on the Emotional Stroop Task?

description: <b><i>Background:</i></b> The insight into psychosis can be assessed reliably by clinicians from interviews with patients. However, patients may retain implicit awareness of illness while lacking explicit awareness. <b><i>Sampling and Methods:</i></b> In a sample of first-episode psychosis patients, we used a test of processing of mental illness-related and other negative words as a measure of implicit awareness to see how this varied in relation to insight. An emotional-counting Stroop task tested reaction times to words of three types: psychosis-related (e.g. ‘crazy'), general negative (e.g. ‘cancer') and neutral (e.g. ‘oyster'). Data were available from 43 patients and 23 healthy controls. Patients' insight was assessed using the Schedule for the Assessment of Insight (SAI-E). <b><i>Results:</i></b> Patients reacted slower than controls to words across all conditions, and both patients and controls reacted slower to salient and negative words than neutral words. There was a near significant interaction between word type and group (Wilks' lambda = 0.53, p = 0.055); patients experienced greater interference from negative rather than psychosis-related words (p = 0.003), and controls experienced greater interference from salient rather than negative words (p = 0.01). Within the patient group, there was a correlation between insight and interference on salient words (r = 0.33, p = 0.05), such that those with less insight experienced less interference on psychosis-related words. <b><i>Conclusions:</i></b> Psychosis-related words were less threatening and less self-relevant to psychosis patients with less insight. This suggests that the lack of awareness such patients have of their illness is genuine and more likely to be mediated by lower-level information processing mechanisms than strategies such as conscious, motivated denial.

title: Supplementary Material for: Purging Behavior Modulates the Relationships of Hormonal and Behavioral Parameters in Women with Eating Disorders

description: <b><i>Background/Aims:</i></b> There is ample consensus that there is a neurophysiological basis for eating disorders (ED). Traits of personality translate into behavioral traits, purging being a well-defined transversal example. The direct implication of steroid hormones on ED has seldom been studied, despite their effects on behavior. <b><i>Methods:</i></b> After psychological interview analysis, 57 ED female patients (31 purgative and 26 nonpurgative) and 17 female controls were studied. Metabolic parameters and analysis of androgen, estrogen and glucocorticoid hormones were determined in parallel to the psychopathological profile (EDI-2 and SCL-90-R) and anthropometric measurements. <b><i>Results:</i></b> Psychometric tests showed clear differences between ED and controls, but there were few hormonal-metabolic significant differences. In purgative ED there were repeated (significant) positive correlations with corticosteroid-binding globulin (CBG) and negative correlations with sex hormone-binding globulin (SHBG) versus eating and general psychopathology. In nonpurging ED there were positive correlations for deoxycortisol, free fatty acids and albumin and negative for aspartate aminotransferase and psychopathological traits. <b><i>Conclusion:</i></b> The data suggest that CBG/corticosteroids and sexual hormones/SHBG are involved in purging behavior and its psychopathology and severity scores. Correlations of selected psychometric data and the CBG/SHBG levels in purging may eventually result in clinical markers. This approach may provide additional clues for understanding the pathogenesis of ED.

title: Supplementary Material for: Internalization of CCR4 and Inhibition of Chemotaxis by K777, a Potent and Selective CCR4 Antagonist

description: CC chemokine receptor 4 (CCR4) is a G protein-coupled receptor that regulates the chemotaxis of Th2 lymphocytes, which are key players in allergic diseases. K777 is a small compound identified in a binding assay using a CCR4 ligand, CCL17. K777 inhibited both CCL17 binding and CCL17-induced chemotaxis in Hut78 cells (IC<sub>50</sub>: 57 and 8.9 nmol/l, respectively). The K777-mediated inhibition of chemotaxis was potent even in the presence of a 10-fold higher concentration of CCL17. The imaging and flow cytometric analyses revealed that K777 induced CCR4 internalization, with a ∼50% reduction of cell surface CCR4. K777 did not inhibit CXCR4-induced chemotaxis or internalization and did not bring about Ca<sup>2+</sup> mobilization by itself. A Scatchard plot analysis of the binding assay using radiolabeled K777 revealed a single high-affinity binding site on the CCR4 molecule. These results indicate that K777 is a selective CCR4 antagonist featuring the potent chemotaxis inhibition, to which the internalization-inducible ability of K777 to hide a part of cell surface CCR4 may contribute.

title: Supplementary Material for: Involvement of the Orexin System in Adrenal Sympathetic Regulation

description: Orexin (hypocretin) is a neuropeptide secreted from hypothalamic neurons that is known to be activated during motivated behaviors and active waking. Presently, our knowledge of orexin is mainly limited to the central nervous system, and the involvement of the orexin system in peripheral tissues has received little attention. In the present study, we analyzed the existence of the orexin system in the adrenal medulla, which is part of the sympathetic nervous system. Orexin and its receptors are expressed in the bovine adrenal medulla. Orexins stimulated intracellular calcium changes and epinephrine release from cultured bovine adrenal medullary cells. Applied orexin decreased expression of prepro-orexin, orexin receptor-1 and orexin receptor-2, suggesting negative feedback regulation in the adrenal gland. Our results indicate involvement of the orexin system in the sympathetic regulation of the adrenal medulla.

title: Supplementary Material for: Secondary Mitral Regurgitation in Heart Failure with Reduced or Preserved Left Ventricular Ejection Fraction

description: Secondary mitral regurgitation (MR) has been extensively studied in heart failure due to reduced ejection fraction. In contrast, the occurrence and the pathogenesis of secondary MR are much less known in heart failure with preserved ejection fraction (HFpEF). The present review aimed at describing this common but ignored feature of HFpEF.

title: Supplementary Material for: Influence of Exclusive Enteral Nutrition Therapy on Bone Density and Geometry in Newly Diagnosed Pediatric Crohn's Disease Patients

description: <b><i>Background and Aims:</i></b> Exclusive enteral nutrition (EEN) induces remission in patients with Crohn's disease (CD). We investigated the short-term impact of EEN on bone quality and muscle mass in children with CD. <b><i>Methods:</i></b> Ten newly diagnosed CD patients (7 male, 10.6-17.7 years of age) were assessed by peripheral quantitative computed tomography (pQCT) at the forearm before starting an 8-weeks treatment with EEN, and after 12 and 52 weeks. No steroids or biologicals were applied. Trabecular and cortical bone mineral density, total bone, and muscle cross-sectional area (CSA) were measured by pQCT and expressed as age- and sex-specific z-scores; size-dependent CSAs were corrected for low height for age. Wilcoxon rank sum test was applied. <b><i>Results:</i></b> Remission at week 12 was achieved in 8 patients; 2 still had mild disease. Initially low trabecular density z-scores improved (+0.3; p = 0.006) at week 12; simultaneously, the increased cortical density z-scores normalized (-0.4; p = 0.027). The low z-score for muscle CSA corrected for height (median -2.5, range -3.49 to -0.97) increased within 12 weeks (+1.0; p = 0.002) with no further improvement thereafter. <b><i>Conclusions:</i></b> The results indicate disturbed bone remodeling and severely impaired muscle mass in newly diagnosed CD children. Bone metabolism and muscle mass improved within 3 months after starting EEN with no further normalization thereafter.

title: Supplementary Material for: Impairment in Natural Killer Cells Editing of Immature Dendritic Cells by Infection with a Virulent <b><i>Trypanosoma cruzi</i></b> Population

description: Early interactions between natural killer (NK) and dendritic cells (DC) shape the immune response at the frontier of innate and adaptive immunity. Activated NK cells participate in maturation or deletion of DCs that remain immature. We previously demonstrated that infection with a high virulence (HV) population of the protozoan parasite <i>Trypanosoma cruzi</i> downmodulates DC maturation and T-cell activation capacity. Here, we evaluated the role of NK cells in regulating the maturation level of DCs. Shortly after infection with HV <i>T. cruzi</i>, DCs in poor maturation status begin to accumulate in mouse spleen. Although infection induces NK cell cytotoxicity and cytokine production, NK cells from mice infected with HV <i>T. cruzi</i> exhibit reduced ability to lyse and fail to induce maturation of bone marrow-derived immature DCs (iDCs). NK-mediated lysis of iDCs is restored by in vitro blockade of the IL-10 receptor during NK-DC interaction or when NK cells are obtained from <i>T. cruzi</i>-infected IL-10 knockout mice. These results suggest that infection with a virulent <i>T. cruzi</i> strain alters NK cell-mediated regulation of the adaptive immune response induced by DCs. This regulatory circuit where IL-10 appears to participate might lead to parasite persistence but can also limit the induction of a vigorous tissue-damaging T-cell response.

title: Supplementary Material for: Effects of Inulin-Type Fructans on Appetite, Energy Intake, and Body Weight in Children and Adults: Systematic Review of Randomized Controlled Trials

description: <b><i>Aim:</i></b> To systematically evaluate the effects of inulin-type fructan (ITF) supplementation on appetite, energy intake, and body weight (BW) in children and adults. <b><i>Methods:</i></b> The MEDLINE, EMBASE, and Cochrane Library databases were searched up to December 2012 for randomized controlled trials (RCTs) that compared the effects of supplementation with well-defined ITF with placebo or no intervention. <b><i>Results:</i></b> For the pediatric population, 4 RCTs (n = 232) met the inclusion criteria. In infants, very limited evidence (1 RCT, n = 62) showed no effect of ITF supplementation on energy intake and BW. One RCT involving 97 nonobese adolescents aged 9 to 13 years found a reduced increase in BW in the oligofructose + inulin (8 g/day) group compared with the control group after 1 year. For the adult population, 15 RCTs (n = 545) met the inclusion criteria. Five RCTs found no effect of ITF supplementation on appetite sensations. Eleven RCTs found no effect of ITF supplementation on daily energy intake or energy intake during a meal tolerance test. Among 3 RCTs that assessed the effect of ITF supplementation on BW, 2 RCTs showed a (significant) reduction in BW. Of 3 RCTs that evaluated body mass index (BMI), 1 RCT showed a significant reduction in BMI in subjects supplemented with ITF. <b><i>Conclusion:</i></b> Limited data suggest that long-term administration of ITF may contribute to weight reduction.
