L-kynurenine is a tryptophan-derived immunosuppressive metabolite and precursor to neurotoxic anthranilate and quinolinate. We evaluated the stereoisomer D-kynurenine as an immunosuppressive therapeutic which is hypothesized to produce less neurotoxic metabolites than L-kynurenine.

L-/D-kynurenine effects on human and murine T cell function were examined in vitro and in vivo (homeostatic proliferation, colitis, cardiac transplant). Kynurenine effects on T cell metabolism were interrogated using [
C] glucose, glutamine and palmitate tracing. Kynurenine was measured in tissues from human and murine tumours and kynurenine-fed mice.

We observed that 1 mM D-kynurenine inhibits T cell proliferation through apoptosis similar to L-kynurenine. Mechanistically, [
C]-tracing revealed that co-stimulated CD4
T cells exposed to L-/D-kynurenine undergo increased β-oxidation depleting fatty acids. Replenishing oleate/palmitate restored effector T cell viability. We administered dietary D-kynurenine reaching tissue kynurenine concentrations of 19 μM, which is close to human kidney (6 μM) and head and neck cancer (14 μM) but well below the 1 mM required for apoptosis. D-kynurenine protected Rag1
mice from autoimmune colitis in an aryl-hydrocarbon receptor dependent manner but did not attenuate more stringent immunological challenges such as antigen mismatched cardiac allograft rejection.

Our dietary kynurenine model achieved tissue concentrations at or above human cancer kynurenine and exhibited only limited immunosuppression. Sub-suppressive kynurenine concentrations in human cancers may limit the responsiveness to indoleamine 2,3-dioxygenase inhibition evaluated in clinical trials.

Evidence-based strategies are needed to support appropriate use of telemedicine for initial outpatient subspecialty consultative visits. To inform such strategies we performed a survey of general pediatricians and pediatric subspecialists about use of telemedicine for patients newly referred for pediatric subspecialty care.

We developed and fielded an e-mail and postal survey of a national sample of 840 general pediatricians and 840 pediatric subspecialists in May and June 2020.

Of 266 completed surveys (17% response rate), 204 (76%) thought telemedicine should be offered for some and 29 (11%) thought telemedicine should be offered for all initial subspecialist visits. Most respondents who indicated telemedicine should be offered for some initial consultations believed this decision should be made by subspecialty attendings (176/204, 86%). Respondents prioritized several data elements to inform this decision, including clinical information and family-based contextual information (e.g., barriers to in-person care, interest in telemedicine, potential communication barriers). Factors perceived to reduce appropriateness of telemedicine for subspecialty consultation included need for interpreter services and prior history of frequent no-shows. Responses from generalists and subspecialists rarely differed significantly.

Survey results suggest potential opportunities to support the appropriate use of telemedicine for initial outpatient pediatric subspecialty visits through structured transfer of specific clinical and contextual information at the time of referral and through strategies to mitigate perceived communication or engagement barriers.

Pediatric physician beliefs about telemedicine for initial outpatient subspecialty consultative visits may inform future interventions to support appropriate telemedicine use.

Considering the projected increase in global demand for this energy storage technology, driven primarily by growth in e-vehicles, and looking at the criticality of some raw materials used in LIBs, the need for an efficient recycling strategy emerges. In this study, current state-of-the-art technologies for LIB recycling are reviewed and future opportunities and challenges, in particular to recover critical raw materials such as lithium or cobalt, are derived. Special attention is paid to the interrelationships between mechanical or thermal pre-treatment and hydro- or pyrometallurgical post-treatment processes. Thus, the unique approach of the article is to link processes beyond individual stages within the recycling chain. It was shown that influencing the physicochemical properties of intermediate products can lead to reduced recycling rates or even the exclusion of certain process options at the end of the recycling chain. More efforts are needed to improve information and data sharing on the exact composition of feedstock for recycling as well as on the processing history of intermediates to enable closed loop LIB recycling. The technical understanding of the interrelationships between different process combinations, such as pyrolytic or mechanical pre-treatment for LIB deactivation and metal separation, respectively, followed by hydrometallurgical treatment, is of crucial importance to increase recovery rates of cathodic metals such as cobalt, nickel, and lithium, but also of other battery components.Emissions of odorous and volatile organic compounds (VOCs) were investigated between two sludge drying methods. A total of 37 chemical compounds were identified and quantified from the off-gases from sludge drying by indirect drying method. The total number of VOCs detected ranged from 3.45 × 10-3 to 4.53 mg/m3, which includes benzene series, volatile organic sulfur, and nitrogenous organic compounds. High emissions were found in the exhaust gas released from drying workshop that used direct drying method. Sulfur dioxide, aromatics, and chlorinated compounds were dominant. Based on the olfactory effect analysis and cancer risk assessment, the main odor-causing gaseous pollutants were methyl mercaptan and methyl sulfide (for indirect sludge drying process) and SO2 (for direct sludge drying process), while the dominant carcinogens were benzene, carbon tetrachloride, chloroform, and methylene. This study provides new insights into the emission characteristics, olfactory effects, and cancer risks of VOCs and odorous compounds in the exhaust gas from thermal sludge drying processes.
The Preschool Speech and Language Program in Ontario, Canada implemented the Focus on the Outcomes of Communication Under Six (FOCUS), an outcome measure, in 2012. This study aimed to investigate commonly experienced facilitators of and barriers to implementing the FOCUS in clinical practice from the perspectives of speech-language pathologists (SLPs).

Thirty-seven SLPs participated in semi-structured interviews to share their experiences adopting the FOCUS in clinical practice. A deductive content analysis of interview transcripts was conducted using the Theoretical Domains Framework (TDF), followed by an inductive analysis to identify sub-themes within each domain.

SLPs frequently encountered barriers within three TDF domains Environmental Context and Resources (e.g., difficulties integrating the FOCUS into assessment sessions and intervention schedules), Beliefs about Consequences (e.g., beliefs that data collected using the FOCUS lack relevance to clinical practice), and Social Influences (e.g., administration of the FOCUS harmed rapport with families). Commonly reported facilitators were found in the Behavioural Regulation (e.g., reminder system) and Environmental Context and Resources (e.g., availability of administrative personnel and technology support) domains.

SLPs identified barriers and facilitators to implementing an evidence-based outcome measure into practice. Insights drawn from SLPs' perspectives will support the design of new methods to improve the implementation of functional outcome measurement tools within programs.

A rapidly expanding body of evidence indicates that excessive activation of the complement system is critically involved in the development of miscarriages. In the CBA/J × DBA/2 murine model of recurrent miscarriage, exaggerated and unrestrained complement activation is reported to be the underlying cause of angiogenic factor imbalance and persistent inflammation. We have previously shown that mesenchymal stem cell (MSC) therapy can significantly reduce the abortion rate in abortion-prone mice through regulating the feto-maternal immune response. In the present study, we hypothesized that MSCs might improve the balance of angiogenic factors at the feto-maternal unit of CBA/J × DBA/2 mice by restraining complement activation and deposition. To explore this hypothesis, autologous adipose tissue-derived mesenchymal stem cells (AD-MSCs) were administered intra-peritoneally to abortion-prone mice on the 4.5th day of gestatrst time that adoptive transfer of MSCs rectifies the disturbed balance of angiogenic factors observed at the feto-maternal unit of CBA/J × DBA/2 mice, in part at least, through inhibiting excessive complement activation and promoting the production of angiogenic factors. Collectively, these alterations seem to play a pivotal role in reducing the abortion rate and improving the intrauterine condition for the benefit of the fetus.MicroRNAs (miRNAs) play important roles in the regulation of cell proliferation, differentiation, apoptosis, and inflammatory responses. MiR-142-5p is an important inflammation-associated miRNA, whose abnormal expression has been associated with a variety of inflammation-related diseases. However, the role and signaling pathways targeted by miR-142-5p in acquired middle ear cholesteatoma (AMEC) have not been fully elucidated. Cyclin-dependent kinase 5 (CDK5), a special member of the CDK family compared with classic cyclins that plays a critical role in the inflammatory response. In this study, we investigated the roles of miR-142-5p and CDK5 in inflammatory responses in AMEC. Our results revealed that the expression of miR-142-5p was significantly reduced in AMEC, and was negatively correlated with the expression of CDK5 (r=-0.5451). We also found that miR-142-5p can inhibit CDK5 expression by directly target 3' untranslated region (UTR) of CDK5. Flavopiridol chemical structure Additionally, our findings indicated that the increased expression of CDK5 induces the secretion of inflammatory cytokines. In order to further confirm the involvement of miR-142-5p in the regulation of the inflammatory response in AMEC through its inhibitory effect on CDK5 expression, we studied the inflammatory response in HaCaT cells transfected with small interfering RNA against CDK5 (si-CDK5) and a miR-142-5p inhibitor. The results confirmed that miR-142-5p regulates the inflammatory response in AMEC by downregulating CDK5. In summary, miR-142-5p directly inhibits the CDK5-mediated upregulation of inflammatory cytokines in AMEC, which makes it a potential therapeutic target in this disease.
