Notably, loss of D3 reduced the clearance of systemic TH in vivo, thereby demonstrating the critical requirement for epidermal D3 in the maintenance of TH homeostasis. In conclusion, our results show that the D3 enzyme is a key TH-signaling component in the skin thereby providing a striking example of a physiological context for deiodinase-mediated TH metabolism, as well as a rationale for therapeutic manipulation of deiodinases in patho-physiological contexts.The thyroid stimulating hormone receptor (TSHR) mutation database, consisting of all known TSHR mutations and their clinical characterizations, was established in 1999. The database contents are updated here with the same website (tsh-receptor-mutation-database.org). The new database contains 638 cases of TSHR mutations 448 cases of gain of function mutations (7 novel mutations and 41 new cases for previously described mutations since its last update in 2012) and 190 cases of loss of function mutations (28 novel mutations and 31 new cases for previously described mutations since its last update in 2012). This database is continuously updated and allows for rapid validation of patient TSHR mutations causing hyper- or hypothyroidism or insensitivity to TSH.n/a.Native cardiac tissue is comprised of heterogeneous cell populations that work cooperatively for proper tissue function; thus, engineered tissue models have moved toward incorporating multiple cardiac cell types in an effort to recapitulate native multicellular composition and organization. Cardiac tissue models comprised of stem cell-derived cardiomyocytes require inclusion of non-myocytes to promote stable tissue formation, yet the specific contributions of the supporting non-myocyte population on the parenchymal cardiomyocytes and cardiac microtissues have yet to be fully dissected. This gap can be partly attributed to limitations in technologies able to accurately study the individual cellular structure and function that comprise intact 3D tissues. The ability to interrogate the cell-cell interactions in 3D tissue constructs has been restricted by conventional optical imaging techniques that fail to adequately penetrate multicellular microtissues with sufficient spatial resolution. Light sheet fluorescence microscopy overcomes these constraints to enable single cell-resolution structural and functional imaging of intact cardiac microtissues. Multicellular spatial distribution analysis of heterotypic cardiac cell populations revealed that cardiomyocytes and cardiac fibroblasts were randomly distributed throughout 3D microtissues. Furthermore, calcium imaging of live cardiac microtissues enabled single-cell detection of cardiomyocyte calcium activity, which showed that functional heterogeneity correlated with spatial location within the tissues. This study demonstrates that light sheet fluorescence microscopy can be utilized to determine single-cell spatial and functional interactions of multiple cell types within intact 3D engineered microtissues, thereby facilitating the determination of structure-function relationships at both tissue-level and single-cell resolution.Purpose To explore and describe the experience of people having young-onset dementia.Methods This was a qualitative study that used semi-structured interviews to collect data from nine persons with young-onset dementia (aged 47-65; five men and four women). Data were collected in the spring of 2018. All interviews were conducted at the participants' choice and in their own homes by one interviewer. The collected data were analysed using the six-stage process of reflexive thematic analysis model.Results The analysis revealed three themes Dementia causing loss of control over oneself; becoming a burden to the family while sense of self disappears; and fearing a humiliating future.Conclusions The experience of having and living with young onset dementia affected the persons' thoughts and memory and was experienced through the persons' loss of personality and sense of self. Thoughts about the future were associated with fear, and the risk of changing their personalities to something different from the one which they had experienced as humiliating throughout most of their lives.Neuroinflammation is associated with the pathogenesis of all types of neurological disease, in which microglial cells play a critical role. In response to disturbances in the microenvironment, microglia become activated and differentiate into either an M1 phenotype, which has a pro-inflammatory, damaging effect, or an M2 phenotype, which plays an anti-inflammatory and reparative role. Thus, modulating microglial polarization is a suitable strategy to treat neuroinflammatory disorders. Glial cell-derived neurotrophic factor (GDNF) is a neurotrophic mediator that exerts neuroprotective effects during neurological diseases. In this study, we predicted that adipose-derived stem cells (ADSCs) could produce GDNF and investigated the effects of GDNF on microglial M1/M2 polarization. Furthermore, we determined whether GDNF modulates microglial activation and polarization via the PI3K/AKT signaling pathway. We found that the secretion of inflammatory cytokines in lipopolysaccharide-stimulated microglia was downgrated, while the anti-inflammatory mediators in interleukin-4-stimulated microglia were upgrated obviously, following pretreatment with ADSCs or GDNF. In addition, GDNF produced by ADSCs inhibited the microglia M1 phenotype and promoted the M2 phenotype by upregulating the PI3K/ATK pathway. These results reveal that GDNF produced by ADSCs might be useful for the treatment of neuroinflammatory diseases.Bone marrow-derived mesenchymal stem cells (BMSCs) have the potential to differentiate into osteoblasts or adipocytes, and an imbalance between adipogenesis and osteogenesis causes age-related bone loss. In this study, we determined the influence of TNF receptor-associated factor 3 (TRAF3) on senescence and osteoblastic and adipocytic differentiation of rat BMSCs. TRAF3 expression increased during osteogenic differentiation but decreased during adipocytic differentiation of rat BMSCs, and compared with day 0 cultures, on day 14, the differences were significant. Overexpression of TRAF3 significantly promoted BMSC osteogenic differentiation and suppressed adipogenic differentiation and senescence. Furthermore, Traf3 was determined to be a target gene of miR-363-3p in BMSCs, and TRAF3 expression in BMSCs was reduced by miR-363-3p overexpression. This overexpression attenuated the effects of TRAF3 on BMSC adipogenic differentiation, osteogenic differentiation, and senescence. Taken together, these results uncovered the mechanism by which TRAF3 promotes BMSC osteogenic differentiation and suppresses adipogenic differentiation and senescence, indicating that the miR-363-3p-TRAF3 axis might be a novel therapeutic target for BMSC-based bone tissue engineering in osteoporosis.The literature refers extensively to the ramifications of the mother's care on her infant. However, little attention has been paid to the effects of maternal caregiving on the emotional experience of the mother herself. Using grounded theory methodology, we sought to contribute to fill this gap, and conducted open indepth interviews with 20 Israeli mothers of infants up to 3 months of age. Three core categories emerged from the interviews Difficulty, Pleasure and Satisfaction, and Concern for Personal Needs. We found these categories to parallel three theoretical concepts relating to caregivers in general compassion fatigue, compassion satisfaction, and self-compassion. Consequently, we propose a new inclusive theoretical concept termed Maternal Compassion Preoccupation. The findings and conceptualization can contribute to the theoretical knowledge associated with early maternal caregiving, and to a new perspective on interventions aimed at helping women to cope with the high care demands of early motherhood.Evidence suggests that pediatric traumatic brain injury (TBI) may be causally related to alcohol misuse later in life; however, the nature and extent of the association has not been well described. This study examined the relationship between pediatric TBI and adult alcohol misuse in a population sample aged ≥20 years. We sought to determine (1) whether first self-reported incidence of TBI with loss of consciousness (LOC) before the age of 20 increased the risk for alcohol misuse later in life; and (2) whether sex, injury severity, and age at time of injury modified the association. We found a greater likelihood of binge but not heavy drinking for those whose first self-reported TBI with LOC occurred before the age of 20 when compared to those whose first occurred later in life (28.5% vs. 20.4%, p = 0.003. When limited to those with only mild TBI, the relationship for binge drinking remained significant (31.9% vs. 19.3%, p less then 0.001) and was evident for both males (38.4% vs. 25.6%, p = 0.016) and females (20.9% vs. 12.4%, p = 0.044). When controlling for sex, age and race/ethnicity, reporting a first TBI with LOC before age 20 was associated with binge drinking only for those with mild TBI (AOR=1.32; 95% CI=1.00-1.74). Results also showed that those with first TBI with LOC occurring between the ages of 10-19 years were more likely to binge drink as adults than those first injured earlier in life, regardless of TBI severity. Further research is needed at both the epidemiological and preclinical levels to better understand this relationship.Purpose To characterize the potential therapeutic effects of idebenone on Leber hereditary optic neuropathy (LHON) in terms of visual acuity (VA), visual field (VF) defects, visual evoked potential (VEP) and retinal nerve fibre layer (RNFL) thickness using optical coherence tomography (OCT) measurements.Methods This was a retrospective case-controlled study of the effect of idebenone (900 mg/d) on 30 patients with LHON due to m.3460 G > A, m.11778 G > A and m.14484 T > C mutations. The primary end-point was the recovery in VA after 3 and 6 mon. The main secondary end-point was the change in VF, VEP and RNFL thickness. The other secondary end-point was the correlation between visual changes after 6 mon and the VF, VEP and RNFL thickness at baseline of the groups.Results Idebenone was shown to be safe and well tolerated. The primary end-point reached statistical significance. The VA in the idebenone group improved in both the best eye and worst eye. see more The mean defect of VF decreased and amplitude of VEP increased. There was no significant difference in latency and RNFL thickness between the groups. The treatment, together with the VA and amplitude at baseline, had a significant effect on the improvement in VA at 6 mon.Conclusion This case-controlled study of LHON provides evidence that idebenone treatment may be beneficial in cases of LHON and that the influential factors governing outcomes are the VA and amplitude of the VEP at baseline.What are the consequences of lay beliefs about how things are made? In this article, we describe a Western folk theory of artifact creation, highlighting how intuitive dualism regarding mental and physical labor (i.e., folk psychology) can lead to the perceived transmission of properties from makers to material artifacts (i.e., folk physics), and affect people's interactions with material artifacts. We show how this folk theory structures the conceptual domain of material artifacts by differentiating the contemporary lay concepts of art/craft and industrial production, and how it influences people's evaluations of different types of artifacts and their makers. We propose that the folk theory and lay concepts of art/craft and industrial production are best understood within a specific sociohistorical context, and review potential sources of cross-cultural and cross-temporal variation. We conclude by making recommendations for future research and examining the implications for promoting environmental sustainability and social justice in production systems.
