Abstract
Psychedelics are being increasingly examined for their therapeutic potential in mood disorders. While the acute effects of ayahuasca, psilocybin, and lysergic acid diethylamide (LSD) last over several hours, inhaled N,N-Dimethyltryptamine (DMT) effects last around 10 min, which might provide a cost- and time-effective alternative to the clinical application of oral psychedelics. We aimed at investigating the safety and tolerability of inhaled DMT (BMND01 candidate). We recruited 27 healthy volunteers to receive a first, lower dose and a second, higher dose (5/20 mg, 7.5/30 mg, 10/40 mg, 12.5/50 mg, or 15/60 mg) of inhaled DMT in an open-label, single-ascending, fixed-order, dose-response study design. We investigated subjective experiences (intensity, valence, and phenomenology), physiological effects (blood pressure, heart rate, respiratory rate, blood oxygen saturation, body temperature), biochemical markers (liver, kidney, and metabolic functions), and adverse events during the acute and post-acute effects of DMT. DMT dose-dependently increased intensity, valence and perceptual ratings. There was a mild, transient, and self-limited increase in blood pressure and heart rate. There were no changes in safety blood biomarkers and no serious adverse events. DMT dose-dependently enhanced subjective experiences and positive valence. Inhaled DMT might be an efficient, non-invasive, safe route of administration, which might simplify the clinical use of this substance. This is the first clinical trial to test the effects of inhaled DMT (BMND01 candidate).

Abstract
Voluntary slow breathing (VSB) is used as a prevention technique to support physical and mental health, given it is suggested to influence the parasympathetic nervous system (PNS). However, to date, no comprehensive quantitative review exists to support or refute this claim. We address this through a systematic review and meta-analysis of the effects of VSB on heart rate variability (HRV). Specifically, we focus on HRV parameters indexing PNS activity regulating cardiac functioning, referred to as vagally-mediated (vm)HRV: (1) during the breathing session (i.e., DURING), (2) immediately after one training session (i.e., IM-AFTER1), as well as (3) after a multi-session intervention (i.e., AFTER-INT). From the 1842 selected abstracts, 223 studies were suitable for inclusion (172 DURING, 16 IM-AFTER1, and 49 AFTER-INT). Results indicate increases in vmHRV with VSB, DURING, IM-AFTER1, and AFTER-INT. Given the involvement of the PNS in a large range of health-related outcomes and conditions, VSB exercises could be advised as a low-tech and low-cost technique to use in prevention and adjunct treatment purposes, with few adverse effects expected.

Abstract
Abstract. The aim of this experiment was to test the immediate effects of slow-paced breathing on executive function. Slow-paced breathing is suggested to increase cardiac vagal activity, and the neurovisceral integration model predicts that higher cardiac vagal activity leads to better executive functioning. In total, 78 participants (41 men, 37 women; Mage = 23.22 years) took part in two counterbalanced experimental conditions: a 3 × 5 min slow-paced breathing condition and a television viewing control condition. After each condition, heart rate variability was measured and participants performed three executive function tasks: the color-word match Stroop (inhibition), the automated operation span task (working memory), and the modified card sorting task (cognitive flexibility). Results showed that performance on executive function tasks was better after slow-paced breathing compared to control, with higher scores observed for Stroop interference accuracy, automated operation span score, and perseverative errors, but not Stroop interference reaction times. This difference in executive function between experimental conditions was not mediated by cardiac vagal activity. Therefore, findings only partially align with predictions of the neurovisceral integration model. Slow-paced breathing appears a promising technique to improve immediate executive function performance. Further studies are recommended that address possible alternative underlying mechanisms and long-term effects.

Abstract
INTRODUCTION Immune thrombocytopenia (ITP) durably affects quality of life in patients. Patient education aims at improving their self-care and psychosocial skills, allowing them be more autonomous, to prevent avoidable complications, and to maintain or improve quality of life. The aim of this study was to assess patients' and caregivers' expectations regarding patient education in ITP. METHOD ITP Patients and caregivers were asked about topics that should be addressed in a patient education program through a digital anonymous survey. Their responses were analyzed both qualitatively and quantitatively. A double-blind keyword attribution of the answers was carried out by two physicians and then faced until consensus was found. RESULTS Thirty-eight ITP patients were included: 68% were less than 50 years old and 84% had chronic ITP. On the other hand, twenty-five caregivers were included. Caregivers raised more topics related to the cognitive domain than patients. The psychoaffective and motivational topics tended to be more represented in patients' responses. Only 53% of topics were mentioned by both patients and caregivers. CONCLUSION These discrepancies emphasize the differences between patients and caregivers' expectations regarding a patient education program in ITP, and thus the relevance of patient-caregiver co-construction of such programs.

Abstract
BACKGROUND Intellectual disabilities often create a state of chronic stress for both the person concerned and their significant others (family, caregivers). The development of stress management methods is therefore important for the reduction of stress in persons with intellectual disability. The aim of this experiment was to investigate the effect of slow-paced breathing on stress symptoms experienced by adolescents with intellectual disabilities during a cognitive task under time pressure. METHOD Fourteen adolescents with intellectual disabilities (Mage = 17.39 years, range 15-19 years) took part in two laboratory sessions - a slow-paced breathing session (experimental condition) and an audiobook session (control condition) - the order of which was counterbalanced across participants. Vagal tone was measured through heart rate variability to index stress management. RESULTS No difference in vagal tone was observed at baseline between experimental and control conditions. Compared with the control condition, vagal tone was significantly higher during the experimental condition. CONCLUSIONS The slow-paced breathing task enhanced stress management to a greater extent than did listening to an audiobook. Slow-paced breathing seems to be an easy to learn stress management technique that appears as an effective auxiliary method of lowering stress in adolescents with intellectual disabilities.

Abstract
This review targets emotional intelligence (EI) in sport and physical activity. We systematically review the available literature and offer a sound theoretical integration of differing EI perspectives (the tripartite model of EI) before considering applied practice in the form of EI training. Our review identified 36 studies assessing EI in an athletic or physical activity context. EI has most often been conceptualized as a trait. In the context of sport performance, we found that EI relates to emotions, physiological stress responses, successful psychological skill usage, and more successful athletic performance. In the context of physical activity, we found that trait EI relates to physical activity levels and positive attitudes toward physical activity. There was a shortage of research into the EI of coaches, officials, and spectators, non-adult samples, and longitudinal and experimental methods. The tripartite model proposes that EI operates on three levels - knowledge, ability, and trait - and predicts an interplay between the different levels of EI. We present this framework as a promising alternative to trait and ability EI conceptualizations that can guide applied research and professional practice. Further research into EI training, measurement validation and cultural diversity is recommended.

Abstract
AIM Contamination by Mollicutes is a significant challenge for research laboratories and biopharmaceutical industry. It leads to alteration of results or production quality as well as loss of time, materials and revenue. These organisms can czoriginate from mammalian, avian, insect, plant or fish cells. Culture-based methods may require 28 days to detect Mollicutes. Traditional microbiology could advantageously be replaced by nucleic acid testing for earlier detection. METHODS AND RESULTS A membrane filtration-based concentration of the Mollicutes has been coupled to real-time transcription-mediated amplification (real-time TMA) to demonstrate these advantages. The eight species required by European Pharmacopoeia have been tested and were detected with sensitivity below 100 CFU per 20-ml sample. Co-culture experiments, in which Mollicutes are grown with CHO-S (suspension) or HEK 293 (adherent) cells, were also performed to respectively mimic a bioreactor or flask contamination. Despite the fact that Mollicutes can attach to or invade mammalian cells, they were consistently detected over multiple days. CONCLUSIONS the sample preparation and amplification method used in this study increases sensitivity and reduces time-to-result for detection of Mollicutes. SIGNIFICANCE AND IMPACT OF THE STUDY the described system allows real-time monitoring for microbial contamination of cell-based processes and products for the biopharmaceutical industry.

Abstract
The proteins present in the thylakoid lumen of higher plant chloroplasts have not been rigorously examined. In this communication we present a simple and rapid procedure for the isolation of the soluble proteins and extrinsic membrane proteins present in the thylakoid lumen from spinach. Our procedure involves extensive washing of the thylakoid membranes followed by Triton X-114 phase partitioning. When analyzed by one-dimensional polyacrylamide gel electrophoresis (PAGE), we obtain results which are very similar to those obtained by Kieselbach et al. using more classical methods [T. Kieselbach, A. Hagman, B. Andersson, W.P. Schroder, J. Biol. Chem. 273 (1998) 6710-6716]. About 25 major proteins are observed upon Coomassie blue staining. Upon two-dimensional isoelectric focusing-sodium dodecyl sulfate-PAGE and either Coomassie blue or silver staining, however, numerous other protein components are resolved. Our findings indicate that the total number of proteins (soluble and extrinsic membrane) present in the lumen may exceed 150.
