These assays revealed that extrinsic, but not eosinophil-intrinsic, IL7R is required for eosinophil reconstitution by HSCs in the adult lung. To determine which external factors may be influencing eosinophil development and survival, we performed a cytokine array analysis between wild-type and IL7Rα-deficient mice and found several differentially regulated proteins. These findings expand on our previous report that IL7R is required not only for proper lymphoid cell development and homeostasis, but also for myeloid cell homeostasis in tissues.In this work, the increase of the Caenorhabditis elegans (C. elegans) lifespan extension using hyper-branched cyclodextrin-based nanosponges (CD-NS) complexing oxyresveratrol (OXY), and the possible inhibition of C. elegans phosphodiesterase type 4 (PDE4) were evaluated. The titration displacement of fluorescein was used to calculate the apparent complexation constant (KF) between CD-NS and OXY. Moreover, PDE4 was expressed in E. coli, purified and refolded in presence of cyclodextrins (CDs) to study its possible inhibition as pharmacological target of OXY. The apparent activity was characterized and the inhibitory effect of OXY on PDE4 displayed a competitive in vitro inhibition corroborated in silico. A maximum increase of the in vivo life expectancy of about 9.6% of using OXY/CD-NS complexes in comparison with the control was obtained, in contrast to the 6.5% obtained with free OXY. No effect on lifespan or toxicity with CD-NS alone was found. These results as a whole represent new opportunities to use OXY and CD-NS in lifespan products.Thirteen buffers were investigated for their effect on the binding of adamantanol to β-cyclodextrin and hydroxypropyl-β-cyclodextrin. Stability constants for the β-cyclodextrin complex ranged from 14,800 to 46,000 M-1, and the binding enthalpies were between -23.2 and -10.4 kJ/mole. Compared to water, the stability constant in seven carboxylic acid buffers (citric acid, maleic acid, fumaric acid, succinic acid, malonic acid, malic acid and tartaric acid) was reduced. All seven buffers exhibited a competitive mechanism. Binding constants for the interaction between β-cyclodextrin and buffers ranged from 4 to 44 M-1, and binding enthalpies were in the range -19 to -11 kJ/mole. There was a relation between the chemical structures of the buffers and their ability to bind to cyclodextrin. All seven buffers had a carbon chain consisting of more than three carbons in the backbone. Hydroxyl groups on the carbon chain decreased the binding affinity. 1H and ROESY NMR spectroscopy supported inclusion of the citric acid into the cyclodextrin cavity, although the results for succinic and maleic acids were ambiguous. The results demonstrated that some buffers can interact with cyclodextrin complexes, and careful considerations are necessary when choosing a buffer for cyclodextrin research.

Healthcare-acquired infections (HAIs) cause substantial morbidity and mortality. Copper appears to have strong antimicrobial properties under laboratory conditions.

To examine the potential effect of copper treatment of commonly touched surfaces in healthcare facilities.

Controlled trials comparing the effect of copper-treated surfaces (furniture or bed linens) in hospital rooms compared with standard rooms on HAIs were included in this systematic review. Two reviewers independently screened retrieved articles, extracted data, and assessed the risk of bias of included studies. The primary outcome was the occurrence of HAIs.

In total, 638 records were screened, and seven studies comprising 12,362 patients were included. All included studies were judged to be at high risk of bias in two or more of the seven domains. All seven studies reported the effect of various copper-treated surfaces on HAIs. Overall, this review found low-quality evidence of potential clinical importance that copper-treated hard surfaces and/or bed linens and clothes reduced HAIs by 27% (risk ratio 0.73, 95% confidence interval 0.57-0.94; I

= 44%, P=0.01).

Given the clinical and economic costs of HAIs, the potentially protective effect of copper treatment appears to be important. The current evidence is insufficient to make a strong positive recommendation. However, it would appear worthwhile and urgent to conduct larger publicly funded clinical trials into the impact of copper treatment.

Hospital drains may be an important reservoir for carbapenemase-producing Enterobacterales (CPE).

To determine prevalence of CPE in hospital drains exposed to inpatients with CPE, relatedness of drain and patient CPE, and risk factors for drain contamination.

Sink and shower drains in patient rooms and communal shower rooms exposed to 310 inpatients with CPE colonization/infection were cultured at 10 hospitals. Using short- and long-read whole-genome sequencing, inpatient and corresponding drain CPE were compared. Risk factors for drain contamination were assessed using multi-level modelling.

Of 1209 exposed patient room and communal shower room drains, 53 (4%) yielded 62 CPE isolates in seven (70%) hospitals. Of 49 CPE isolates in patient room drains, four (8%) were linked to prior room occupants. Linked drain/room occupant pairs included Citrobacter freundii ST18 isolates separated by eight single nucleotide variants (SNVs), related bla

-containing IncN3-type plasmids (different species), related bla

-containing IncN-type plasmids (different species), and related bla

-containing IncL/M-type plasmids (different species). In one hospital, drain isolates from eight rooms on two units were Enterobacter hormaechei separated by 0-6 SNVs. Shower drains were more likely to be CPE-contaminated than hand hygiene (odds ratio 3.45; 95% confidence interval 1.66-7.16) or patient-use (13.0; 4.29-39.1) sink drains. Hand hygiene sink drains were more likely to be CPE-contaminated than patient-use sink drains (3.75; 1.17-12.0).

Drain contamination was uncommon but widely dispersed. Drain CPE unrelated to patient exposure suggests contamination by undetected colonized patients or retrograde (drain-to-drain) contamination. Drain types had different contamination risks.

To promote healthy eating, nutrition labels have been mandated to certain foods in many countries. To test how different designs of nutrition labels affect consumer behavior, eye tracking technique has been increasingly used to overcome the limitations of subjective report which are susceptible to different biases and a poor indicator of nutrition label use in reality. In this review, we reviewed 45 eye-tracking studies on nutrition label processing. Besides a summary of eye tracking methodology, we found three emerged topics from these studies attention capture, nutrition label comprehension and food choice. Overall, updated designs of nutrition labels improve attention capture and nutrition label comprehension, but it does not necessarily lead to healthier food choices. The discrepancy between attention capture and food choice also indicate potential limitation in promoting healthy food choice via the indirect attention route (exposure - attention - nutrition label processing - food choice). Instead, actual food choice may be a consequence of a direct heuristic route and modulated by person-, product- and context-related factors. These findings can not only guide future studies, but also have implications on making nutrition label policy and improving human health in eastern developing countries.Understanding consumer perceptions of meat alternatives is key to facilitating a shift toward more sustainable food consumption. Importantly, these perceptions may vary according to the characteristics of the consumer (e.g., preferences, motivations), the product (e.g., sensory attributes) and the encounter (e.g., how the meat alternative is presented/framed). Qualitative and quantitative methods were applied to examine consumer perceptions of five proposed alternatives to meat legumes, tofu, seitan, lab-grown meat, and insects. In Study 1, 138 participants provided free associations with regards to conventional animal proteins (e.g., red/white meat, fish) and the five alternatives. Three profiles of consumers were identified (1) hedonically motivated meat eaters uninterested in meat substitutes; (2) health-oriented meat eaters open to some meat substitutes; and (3) ethically conscious meat avoiders positively oriented to most meat alternatives. In Study 2, the presentation of the product was experimentally manipulated 285 participants evaluated the same five meat alternatives along several dimensions (e.g., edibility, healthiness), either when framed as an individual product or as part of a larger meal. Overall, most meat alternatives benefited from a meal framing, with the notable exception of legumes, which benefited from an individual framing, and insects which were evaluated quite negatively regardless of framing. The present findings suggest that there is not a single way to frame all meat alternatives that will improve their appeal to all consumers.

The effectiveness of intracanal cryotherapy for reducing postoperative pain is unclear. The objective of this systematic review was to evaluate the effect of intracanal cryotherapy on postoperative pain after root canal therapy in patients with pulpal or periradicular pathosis.

We searched PubMed, Embase, Scopus, and the Cochrane Library as well as the top 3 endodontic journals for relevant articles. We included randomized controlled trials that included adults. Our main outcome was postoperative pain intensity measured with a validated scale. We assessed the risk of bias using the Cochrane criteria and the quality of the included studies using Grading of Recommendation Assessment, Development, and Evaluation. We used a random-effects model for meta-analysis.

Eight studies involving 810 patients were included. The overall risk of bias was moderate. Seven of 8 studies used a visual analog scale to measure pain intensity. Compared with controls, intracanal cryotherapy significantly reduced postoperative pain at 6 (mean difference = -1.37; 95% confidence interval [CI], -0.61 to -2.14; P < .05; I

= 76%; moderate-quality evidence) and 24 hours after the procedure (mean difference = -1.43; 95% confidence interval, -0.70 to -2.15; P < .05; I

= 89%; moderate-quality evidence). There was no significant effect on pain at 48 and 72 hours and 7 days after the procedure.

Moderate-quality evidence suggests that intracanal cryotherapy (ie, using cold saline irrigation as a final irrigant) significantly reduces the intensity of pain at 6 and 24 hours after root canal therapy. Future clinical trials assessing the effectiveness of intracanal cryotherapy are advocated.
