Genomics of Preaxostyla Flagellates Illuminates the Path Towards the Loss of Mitochondria.

The notion that mitochondria cannot be lost was shattered with the report of an oxymonad Monocercomonoides exilis, the first eukaryote arguably without any mitochondrion. Yet, questions remain about whether this extends beyond the single species and how this transition took place. The Oxymonadida is a group of gut endobionts taxonomically housed in the Preaxostyla which also contains free-living flagellates of the genera Trimastix and Paratrimastix. The latter two taxa harbour conspicuous mitochondrion-related organelles (MROs). Here we report high-quality genome and transcriptome assemblies of two Preaxostyla representatives, the free-living Paratrimastix pyriformis and the oxymonad Blattamonas nauphoetae. We performed thorough comparisons among all available genomic and transcriptomic data of Preaxostyla to further decipher the evolutionary changes towards amitochondriality, endobiosis, and unstacked Golgi. Our results provide insights into the metabolic and endomembrane evolution, but most strikingly the data confirm the complete loss of mitochondria for all three oxymonad species investigated (M. exilis, B. nauphoetae, and Streblomastix strix), suggesting the amitochondriate status is common to a large part if not the whole group of Oxymonadida. This observation moves this unique loss to 100 MYA when oxymonad lineage diversified.

Influence of fentanyl, medetomidine-fentanyl or acepromazine-fentanyl premedication on oesophageal and rectal temperature in dogs under anaesthesia.

OBJECTIVE: To compare changes in oesophageal (T-Oeso) and rectal (T-Rec) temperature in dogs during general anaesthesia and premedicated with fentanyl, medetomidine-fentanyl or acepromazine-fentanyl. STUDY DESIGN: Prospective, randomized, blind clinical study. ANIMALS: A total of 120 healthy dogs, aged 2-10 years and weighing 5-20 kg. METHODS: Dogs were randomly allocated to one of three groups. Animals of F group were premedicated with fentanyl (0.01 mg kg-1), MF group with medetomidine (0.005 mg kg-1) and fentanyl (0.01 mg kg-1) and AF group with acepromazine (0.01 mg kg-1) and fentanyl (0.01 mg kg-1). Anaesthesia was induced with propofol and maintained with isoflurane in oxygen-air mixture. Fentanyl was administered continuously (0.01 mg kg-1 hour-1). The T-Oeso, T-Rec and ambient temperatures were recorded after induction (T0) and subsequently at 10 minute intervals for 60 minutes (T10-T60). Data were analysed using anova or their non-parametric equivalents (p < 0.05). RESULTS: Median T-Oeso was significantly higher in MF group between T0-T20 compared with other groups. Median T-Oeso significantly decreased in F group from 38.0 °C (T0) to 37.4 °C (T30), 37.1 °C (T40), 36.9 °C (T50) and 36.6 °C (T60), in MF group from 38.3 °C (T0) to 37.7 °C (T30), 37.5 °C (T40), 37.2 °C (T50) and 37.1 °C (T60) and in AF group from 37.7 °C (T0) to 37.3 °C (T40), 37.2 °C (T50) and 37.1 °C (T60). The T-Rec significantly decreased in F group from 38.0 °C (T0) to 37.4 °C (T40), 37.2 °C (T50) and 36.9 °C (T60), in MF group from 38.3 °C (T0) to 37.5 °C (T50) and 37.4 °C (T60) and in AF group from 38.2 °C (T0) to 37.6 °C (T40), 37.5 °C (T50) and 37.4 °C (T60). CONCLUSIONS AND CLINICAL RELEVANCE: Premedication with fentanyl, medetomidine-fentanyl or acepromazine-fentanyl in the doses used decreased the T-Oeso and T-Rec. The T-Oeso at the beginning of anaesthesia was higher after premedication with medetomidine-fentanyl. However, this difference was not clinically significant.

A Czech version of the Overall Anxiety Severity and Impairment Scale (OASIS): standardization and psychometric properties.

BACKGROUND: The Overall Anxiety Severity and Impairment Scale (OASIS) is a transdiagnostic measure that assesses severity and impairment associated with anxiety disorders. However, its psychometric properties were primarily examined in English-speaking or western countries. Therefore, this study aims to examine its psychometric parameters in the Czech Republic. METHODS: A large representative sample (n = 1738), a clinical sample (n = 57) and a retest sample (n = 20) were used. In addition to the OASIS, conventional measures of anxiety, depression, personality traits, self-esteem, life satisfaction, and other scales were also administered. Moreover, we examined the latent structure, reliability, validity, and the cut-off score for the Reliable Change Index (RCI) and the Clinically Significant Change Index (CSI). RESULTS: Higher anxiety was found in females, religious non-church members, and students. The Confirmatory Factor Analysis supported the adequate fit of the unidimensional solution: x2(4) = 3.20; p < 0.525; CFI = 1.000; TLI = 1.000;RMSEA = 0, SRMR = 0. The measurement equivalence examination indicated that the OASIS measures anxiety invariantly between males and females. The validity of the OASIS was supported by positive associations with neuroticism, depression, perceived stress, guilt, shame, and the established anxiety measures. The internal consistency was excellent (Cronbach's alpha = 0.96, McDonald's omega = 0.96). The test-retest reliability was acceptable (r = 0.66). The cut-off for the CSI is 6 and the RCI is 5.32. CONCLUSIONS: The OASIS represents a reliable and valid instrument for assessing anxiety in adults. Due to its shortness, excellent psychometric properties, and percentile norms, it is especially useful for short and accurate screening of anxiety and mapping therapeutic changes in clinical practice.

Influence of anaesthetics on aqueous tear production in dogs: a systematic review.

OBJECTIVE: The aim of this systematic review is to summarize outcomes of studies focused on the effects of opioids, injectable sedative and anaesthetic drugs and inhalant anaesthetics on tear production in dogs. This manuscript complements the systematic review describing the effect of anaesthetics on intraocular pressure in dogs (Pierce-Tomlin et al. 2020). Databases used A detailed search of scientific references has been performed. PubMed, Web of Science, Science Direct and Google Scholar databases were used to search for sources using free text terms 'Dog' or 'Canine', 'Anaesthesia' or 'Anaesthetic' or 'Sedative' or 'Opioid' or the name of used opioids, sedative and anaesthetic drugs and 'Tear' or 'Schirmer' or 'Lacrimation'. The time frame searched was from 1960 to October 2021. Any published manuscripts that were concerned with sedative or anaesthetic drugs administered systemically in the dog and tear production were evaluated. CONCLUSIONS: Low doses of α2-adrenoceptor agonists, neuroleptics, benzodiazepines, opioids, propofol or alfaxalone administered alone have no clinically significant effect on aqueous tear production in healthy dogs measured by the Schirmer tear test I (STT-I). Intramuscular injection of ketamine increases STT-I values. Higher doses of α2-adrenoceptor agonists and combinations of anaesthetics, including inhaled anaesthetics, always clinically significantly decrease tear production.

The Oxymonad Genome Displays Canonical Eukaryotic Complexity in the Absence of a Mitochondrion.

The discovery that the protist Monocercomonoides exilis completely lacks mitochondria demonstrates that these organelles are not absolutely essential to eukaryotic cells. However, the degree to which the metabolism and cellular systems of this organism have adapted to the loss of mitochondria is unknown. Here, we report an extensive analysis of the M. exilis genome to address this question. Unexpectedly, we find that M. exilis genome structure and content is similar in complexity to other eukaryotes and less "reduced" than genomes of some other protists from the Metamonada group to which it belongs. Furthermore, the predicted cytoskeletal systems, the organization of endomembrane systems, and biosynthetic pathways also display canonical eukaryotic complexity. The only apparent preadaptation that permitted the loss of mitochondria was the acquisition of the SUF system for Fe-S cluster assembly and the loss of glycine cleavage system. Changes in other systems, including in amino acid metabolism and oxidative stress response, were coincident with the loss of mitochondria but are likely adaptations to the microaerophilic and endobiotic niche rather than the mitochondrial loss per se. Apart from the lack of mitochondria and peroxisomes, we show that M. exilis is a fully elaborated eukaryotic cell that is a promising model system in which eukaryotic cell biology can be investigated in the absence of mitochondria.

Fe-S Cluster Assembly in Oxymonads and Related Protists.

The oxymonad Monocercomonoides exilis was recently reported to be the first eukaryote that has completely lost the mitochondrial compartment. It was proposed that an important prerequisite for such a radical evolutionary step was the acquisition of the SUF Fe-S cluster assembly pathway from prokaryotes, making the mitochondrial ISC pathway dispensable. We have investigated genomic and transcriptomic data from six oxymonad species and their relatives, composing the group Preaxostyla (Metamonada, Excavata), for the presence and absence of enzymes involved in Fe-S cluster biosynthesis. None possesses enzymes of mitochondrial ISC pathway and all apparently possess the SUF pathway, composed of SufB, C, D, S, and U proteins, altogether suggesting that the transition from ISC to SUF preceded their last common ancestor. Interestingly, we observed that SufDSU were fused in all three oxymonad genomes, and in the genome of Paratrimastix pyriformis. The donor of the SUF genes is not clear from phylogenetic analyses, but the enzyme composition of the pathway and the presence of SufDSU fusion suggests Firmicutes, Thermotogae, Spirochaetes, Proteobacteria, or Chloroflexi as donors. The inventory of the downstream CIA pathway enzymes is consistent with that of closely related species that retain ISC, indicating that the switch from ISC to SUF did not markedly affect the downstream process of maturation of cytosolic and nuclear Fe-S proteins.

Arginine deiminase pathway enzymes: evolutionary history in metamonads and other eukaryotes.

BACKGROUND: Multiple prokaryotic lineages use the arginine deiminase (ADI) pathway for anaerobic energy production by arginine degradation. The distribution of this pathway among eukaryotes has been thought to be very limited, with only two specialized groups living in low oxygen environments (Parabasalia and Diplomonadida) known to possess the complete set of all three enzymes. We have performed an extensive survey of available sequence data in order to map the distribution of these enzymes among eukaryotes and to reconstruct their phylogenies. RESULTS: We have found genes for the complete pathway in almost all examined representatives of Metamonada, the anaerobic protist group that includes parabasalids and diplomonads. Phylogenetic analyses indicate the presence of the complete pathway in the last common ancestor of metamonads and heterologous transformation experiments suggest its cytosolic localization in the metamonad ancestor. Outside Metamonada, the complete pathway occurs rarely, nevertheless, it was found in representatives of most major eukaryotic clades. CONCLUSIONS: Phylogenetic relationships of complete pathways are consistent with the presence of the Archaea-derived ADI pathway in the last common ancestor of all eukaryotes, although other evolutionary scenarios remain possible. The presence of the incomplete set of enzymes is relatively common among eukaryotes and it may be related to the fact that these enzymes are involved in other cellular processes, such as the ornithine-urea cycle. Single protein phylogenies suggest that the evolutionary history of all three enzymes has been shaped by frequent gene losses and horizontal transfers, which may sometimes be connected with their diverse roles in cellular metabolism.

Catching bird flu in a droplet.

It is assumed that a timely mass administration of antiviral drugs, backed by quarantines and social distancing, could contain a nascent influenza epidemic at its source, provided that the first clusters of cases were localized within a short time. However, effective routine surveillance may be impossible in countries lacking basic public health resources. For a global containment strategy to be successful, low-cost, easy-to-use handheld units that permit decentralized testing would be vital. Here we present a microfluidic platform that can detect the highly pathogenic avian influenza virus H5N1 in a throat swab sample by using magnetic forces to manipulate a free droplet containing superparamagnetic particles. In a sequential process, the viral RNA is isolated, purified, preconcentrated by 50,000% and subjected to ultrafast real-time RT-PCR. Compared to commercially available tests, the bioassay is equally sensitive and is 440% faster and 2,000-5,000% cheaper.

Neural bases of social deficits in ADHD: A systematic review. Does the Theory of Mind matter?

INTRODUCTION: The Attention Deficit Hyperactivity Disorder (ADHD) causes serious interpersonal problems from childhood to adulthood, one of them being problematic social functioning. This phenomenon in ADHD should be associated with impairments in the Theory of Mind (ToM). Therefore, understanding the neural correlates of the ToM could be crucial for helping individuals with ADHD with their social functioning. Thus, we aimed to review published literature concerning neuroanatomical and functional correlates of ToM deficits in children and adolescents with ADHD. METHODS: We reviewed studies published between 1970 and 2023. In accordance with PRISMA guidelines, after data from three databases were collected, two authors (LN and PM) independently screened all relevant records (n=638) and consequently, both authors did the data extraction. The quality of the included studies (n=5) was measured by a modified version of The Newcastle-Ottawa Scale and by measures specific for our study. This systematic review was registered on PROSPERO (CRD42020139847). RESULTS: Results indicated that impairments in performing of the ToM tasks were negatively associated with the grey matter volume in the bilateral amygdala and hippocampus in both, ADHD and control group. In EEG studies, a significantly greater electrophysiological activity during ToM tasks was observed in the, frontal, temporal, parietal and occipital lobes in participants with ADHD as compared to healthy subjects. CONCLUSION: More research is needed to explore the ToM deficits in children with ADHD. Future research might focus on the neural circuits associated with attention and inhibition, which deficits seems to contribute to the ToM deficits in children and adolescents with ADHD.

Effects of the COVID-19 pandemic on Czech citizens: how do depression and anxiety symptoms influence cognitive, behavioral, and emotional changes?

Background: This study examined the impact of anxiety and depression symptoms during the first stage of the COVID-19 pandemic on the behavioral, cognitive, and emotional changes of the Czech population. Methods: The research sample (n = 2363; 48.83 ± 16.53 years; 50.15% men) was obtained using an online survey. Depression and anxiety symptoms were measured using the Overall Depression Severity and Impairment Scale (ODSIS) and the Overall Anxiety Severity and Impairment Scale (OASIS) and associations were adjusted for age, gender, and economic status. Results: The results showed that increased symptoms of anxiety and depression were significantly linked to feelings of loneliness, helplessness, reduced quality of relationship with a partner, higher probabilities of alcohol abuse, food consumption, and contemplation of existential questions. Higher symptoms of anxiety were associated with feelings of being threatened. Higher symptoms of depression symptoms increased tobacco abuse. Conclusion: During the first stage of the COVID-19 pandemic, higher symptoms of anxiety and depression among Czech citizens were associated with behavioral, cognitive, and emotional changes.

Is the concept of personality capacious enough to incorporate virtues?

We will consider four answers to the question about whether the concept of personality is capacious enough to incorporate virtues. The simplest is that the concept of personality encompasses all individual variations in persons. It follows from this answer that virtues would, as individual differences, be incorporated into personality. Unfortunately, definitions of personality do not always invoke such capaciousness, and, in practice, most scholars limit their work to the Big Five or HEXACO models, which do not incorporate virtues. The second answer is that the concept of personality incorporates all trait or dimension level variations across persons, with some exceptions, such as intelligence, attachment style, and psychopathy. Following this definition, virtues, as traits, would be incorporated into such a broad definition of personality. Unfortunately, the boundaries for inclusion and exclusion into personality are fuzzy in this case, and there is no extant definition of personality that solves this problem. The third answer is that personality traits and virtue traits are similar, but distinct concepts. This article presents conceptual and empirical arguments for this similarity in seeing traits as a higher order concept that includes the species of personality and the species of virtue. The fourth answer is that personality and virtue are unrelated. This answer is dismissed because there are many studies that indicate that they are correlated, and few advocate such a clear differentiation. The conclusion is that, pending conceptual and empirical results indicating otherwise, the genus-species relationship seems most fitting where traits are a genus, and personality and virtue are each a species within that genus.

The stability of the twofold multidimensionality of academic self-concept: A study of Chinese secondary school students.

Introduction: The present investigation examined the stability of the twofold multidimensional structure of academic self-concepts (ASCs) in three domains, namely Chinese, math, and general school using four-wave data collected over 2 years among 552 Chinese secondary school students. Method: Adopting both a within-network and a between-network approach, confirmatory factor analyses (CFAs) and factor correlations were performed in Mplus 8.2. Results: The within-network results showed that CFA models wherein competence and affect dimensions were conflated generated unacceptable fit. In contrast, the CFAs in which competence and affect were modeled as separate latent factors consistently produced superior fit to the data. The between-network results demonstrated that in the Chinese and math domains and across the four-time waves, the competence components were more strongly related to the achievements in matching domains than the affect components were. Furthermore, both the competence and affect components of ASCs and achievements were positively correlated in the non-matching domains, which were somewhat contradictory to the internal/external frame of reference model predicting zero or negative relations. Discussion: Such results seem to suggest more involvement in social comparison than in dimensional comparison of Chinese students, which might be attributed to the collectivistic Chinese culture and the common phenomenon of academic social comparisons among Chinese adolescents in schools.

Influence of Methadone on Intraocular Pressure, Pupil Size, and Aqueous Tear Production in Healthy Dogs.

Intraocular pressure (IOP), pupil size (PS), and tear production are variables important in maintaining eye homeostasis. The purpose of this study was to determine the effects of methadone on IOP, PS, and tear production measured by Schirmer I tear test (STT-I) in healthy nonpainful dogs. A prospective, randomized, "double-blind" clinical study was performed. A total of 40 healthy conscious client-owned dogs were included in the study. Dogs were allocated randomly to 1 of 3 groups and given intravenous methadone 0.3 mg/kg (Met-IV, n = 15), intramuscular methadone 0.3 mg/kg (Met-IM, n = 15), or saline 0.3 mL/kg (SAL, n = 10). IOP, PS, STT-I, heart rate (HR), and mean arterial pressure (MAP) were measured prior to (baseline) and at 2, 5, 10, 20, and 30 minutes after drug administration. Data were analyzed using 1-way and 2-way repeated measures ANOVA or their nonparametric equivalents (P < .05). No significant differences in IOP and PS within or between the groups were detected. In the Met-IV group, the STT-I decreased significantly after 30 minutes (P = .025), however, the values remained within the physiological ranges. In Met-IV group, HR decreased significantly at 5, 10, 20, and 30 minutes, respectively. No other significant differences were observed. Methadone administered at a dose of 0.3 mg/kg intravenously or intramuscularly seems to cause within 30 minutes no clinically important effect on IOP, PS, and STT-I in healthy conscious nonpainful dogs without ocular abnormalities.

Influence of Fentanyl, Ketamine, and Lidocaine on Tear Production in Healthy Conscious Dogs.

Tear production is an important factor in maintaining proper function of the cornea and conjunctiva. The purpose of this study was to determine the effects of bolus followed by infusion of fentanyl, lidocaine, and ketamine on tear production as measured by the Schirmer I Tear Test (STT-I) in dogs. A prospective, randomized, "double-blind" study was performed. A total of 55 healthy conscious client-owned dogs were included in the study. Dogs were randomly allocated to one of four groups and given intravenous fentanyl 0.005 mg kg-1 followed by 0.005 mg kg-1 hour-1 (FEN-group), ketamine 0.6 mg kg-1 followed by 0.6 mg kg-1 hour-1 (KET-group), lidocaine 1 mg kg-1 followed by 1 mg kg-1 hour-1 (LID-group), or saline 0.3 mL kg-1 followed by 2 mL kg-1 hour-1 (SAL-group). The STT-I was performed prior to (baseline) and again 30 minutes (T30) after initiation of drug administration. Data were expressed as the median (minimum - maximum) and analyzed by Wilcoxon and Steel-Dwass tests (P < .05). The STT-I values increased little but were statistically significant in the KET-group from 18 (14-23) to 19 (14-25) (P = .039) and in the LID-group from 21 (14-25) to 20 (17-29) (P = .027). At 30 minutes, STT-I values were significantly higher in LID-group 20 (17-29) than in FEN-group 18 (12-22) (P = .006). Fentanyl, ketamine, and lidocaine administered at the studied doses as a bolus and then followed by an infusion within 30 minutes in healthy conscious dogs demonstrated a clinically insignificant effect on tear production as measured by STT-I.

The Associations of Experiencing the COVID-19 Pandemic With Religiosity and Spirituality: A Cross-Sectional Study in Czech Adults.

Objectives: We investigated the associations between religiosity/spirituality and respondents' changes in their relationships, feelings, thinking, and behaviour during the first wave of the COVID-19 pandemic in the Czech Republic. Methods: A sample of Czech adults (n = 1,434; 48.3 ± 16.4 years; 49.65% women) participated in the online survey. We measured spirituality, religiosity, self-reported changes in relationships, disrupted feelings, and changes in behaviour during the pandemic. Results: Spiritual respondents were more likely to report increased physical activity, sex, reading and self-education, with odds ratios (ORs) ranging from 1.26 (95% confidence interval 1.09-1.46) to 1.56 (1.31-1.86). The combination of spirituality and religiosity led to an increase in the range of ORs to 1.57-2.69. Spiritual and religious participants were less likely to feel the decrease of hope by 70%, while mere spirituality significantly reduced the decrease of hope by only 30%. Religiosity itself led to a lower risk of reporting a disrupted day structure with an OR = 0.74 (0.58-0.95). Conclusion: Religiosity and spirituality separately help people during a pandemic in some areas. Especially their combination has a more positive impact on relationships, feelings, and behaviour.

Neural correlates of compassion - An integrative systematic review.

Compassion is a psychological construct that has received increasing attention in recent years. Even though a lot of work has been done to identify neural correlates of empathy across studies, such work has not been properly done on neural correlates of compassion. Therefore, the aim was to systematically review the literature on neural correlates of compassion. We have searched through PsycINFO, PubMed and Web of Science for relevant articles published between 1985 and 2020. We included the studies (n = 35) examining the relationship between brain structure or function and compassion. Screening was performed by two authors, between whom a level of agreement was calculated. The quality of the studies was assessed by measures used in other studies as well by measures specific for our study aims. This study was conducted under PRISMA guidelines. Our analysis revealed that the most frequent neural associations with compassion across all analysed studies can be found in the orbital part of the left inferior frontal gyrus, in the right cerebellum, the bilateral middle temporal gyrus, in the bilateral insula and the right caudate nucleus. Our findings suggest that people displaying a lower compassion tend to have either lower neural activity or a grey matter volume in neural areas associated with reward.

Religious Conspiracy Theories About the COVID-19 Pandemic Are Associated With Negative Mental Health.

Objectives: Together with the COVID-19 pandemic, conspiracy theories have begun to spread. Evidence is lacking for religious conspiracy theories (RCT) related to COVID-19 in a non-religious environment. This study aimed to assess links between religiosity and spirituality (R/S) and RCT about COVID-19, and to examine their associations with mental health. Methods: A sample of Czech adults (n = 1,273, mean age = 47.5, SD = 16.4; 51.5% male) participated in the survey. We measured R/S, RCT, negative religious coping (NRC), feelings impairment and mental health symptoms. Results: We found R/S were significantly associated with RCT with ß 0.71 (95% confidence interval [CI] 0.59-0.82) for the strongest association. Moreover, RCT and NRC were strongly associated with paranoia, anxiety and depression. The most frequent association was found for NRC and paranoid ideation, with ß of 0.35 (95% CI 0.26-0.44). Conclusion: Our findings showed associations between religiosity/spirituality and beliefs in religious conspiracy theories about COVID-19. Moreover, these RCT and negative religious coping were linked to higher possibility of mental health problems. Understanding these associations may help prevent this negative impact and contribute to the effectiveness of psychotherapeutic help.

Sensory Processing Sensitivity Questionnaire: A Psychometric Evaluation and Associations with Experiencing the COVID-19 Pandemic.

Sensory processing sensitivity (SPS) is a common human neurobiological trait that is related to many areas of human life. This trait has recently received increased public interest. However, solid scientific research on SPS is lagging behind. Progress in this area is also hindered by a lack of comprehensive research tools suitable for a rapid assessment of SPS. Thus, the aim of this study was to offer a newly developed tool, the Sensory Processing Sensitivity Questionnaire (SPSQ), and to assess its psychometric properties and associations with emotional and relational variables measured during the first wave of the COVID-19 pandemic. We found the tool to have good psychometric characteristics: high temporal stability (r = 0.95) and excellent internal consistency (Cronbach's α = 0.92; McDonald's ω = 0.92). The fit of the SPSQ bi-factor model was satisfactory: χ2 (88.0) = 506.141; p < 0.001; CFI = 0.993; TLI = 0.990; RMSEA = 0.070; SRMR = 0.039. Testing of configural, metric, scalar and strict invariance suggested that the SPSQ assesses SPS equivalently between males and females. The scale's validity was supported via a strong association with an existing SPS measure. Further, we observed higher total SPSQ scores among women, students and religious respondents, and we found that more sensitive respondents reported higher feelings of anxiety and more deterioration in relationships during the COVID-19 pandemic. Thus, this study also identifies people with this trait as being potentially more vulnerable during periods of an increased presence of global stressors.
