Subsequent exposure to atmospheric oxygen upon oviposition initiates recommencement of embryonic development. Arrest can be artificially extended for several days after oviposition by incubation of the egg under hypoxic conditions, with development recommencing in an apparently normal fashion after subsequent exposure to normoxia. To examine the transcriptomic events associated with embryonic arrest in green sea turtles (Chelonia mydas), RNA-sequencing analysis was performed on embryos from freshly laid eggs and eggs incubated in either normoxia (oxygen tension ~159 mmHg) or hypoxia ( less then 8 mmHg) for 36 h after oviposition (n = 5 per group). The patterns of gene expression differed markedly among the three experimental groups. Normal embryonic development in normoxia was associated with upregulation of genes involved in DNA replication, the cell cycle, and mitosis, but these genes were commonly downregulated after incubation in hypoxia. Many target genes of hypoxia inducible factors, including the gene encoding insulin-like growth factor binding protein 1 (igfbp1), were downregulated by normoxic incubation but upregulated by incubation in hypoxia. Notably, some of the transcriptomic effects of hypoxia in green turtle embryos resembled those reported to be associated with hypoxia-induced embryonic arrest in diverse taxa, including the nematode Caenorhabditis elegans and zebrafish (Danio rerio). Hypoxia-induced preovipositional embryonic arrest appears to be a unique adaptation of turtles. However, our findings accord with the proposition that the mechanisms underlying hypoxia-induced embryonic arrest per se are highly conserved across diverse taxa.
Many survivors of severe or critical COVID-19 have required rehabilitation during the pandemic. The primary objective was to compare characteristics and outcomes of survivors of severe or critical COVID-19 admitted to the inpatient rehabilitation facility (IRF) during the first two waves of the pandemic. Our secondary objective was to identify the factors contributing to functional dependence on admission, discharge and length of stay.

Retrospective cohort study of 138 patients admitted to an IRF in two waves following hospitalization for severe or critical COVID-19 illness between April 1, 2020 and May 3, 2021.

IRF patients in wave 2 had significantly greater functional independence (GG scores) on admission (52, IQR44-58 versus 41, IQR 28-52), lower incidence of dysphagia and anemia. Patients in both waves experienced similar functional improvement efficiencies with a median GG score change of 3.6 per day and similar discharge GG scores. Neurological sequela (OR 0.12, P < 0.001) and anemia (OR 1.35, P < 0.002) were identified as independent predictors of functional independence on admission.

Patients with functional deficits after COVID-19 should be considered for acute inpatient rehabilitation as both patient cohorts benefited from their IRF stays with similar length of stays (11-12 days) and discharge to home rates (88- 90%).

Even in limiting structure space to a single structure type, many different compositions and configurations are possible. In this work, we attempt to address this problem using an extension to the existing ChemDASH code in which variable compositions can be explored. We show that ChemDASH is an efficient method for exploring a fixed-composition space of spinel structures and build upon this to include variable compositions in the Mn-Fe-Zn-O spinel phase field. This work presents the first basin-hopping crystal structure prediction method that can explore variable compositions.
Denim sandblasting-induced silicosis is a recently identified occupational disease.

In this study, we aimed to evaluate pulmonary and radiological changes in the long-term follow-up of former denim sandblasters.

Ninety former denim sandblasters were followed from 2007 to 2018. Chest X-rays were evaluated according to the International Labour Organization (ILO) classification. Baseline and final data were compared. Silicosis prevalence, radiological progression and pulmonary dysfunction were evaluated.

All of the sandblasters were men. Their mean age was 34 ± 5 years, mean follow-up time was 9 ± 2 years (mean time since initial exposure 17 ± 2 years) and mean duration of exposure was 34 ± 25 months. Rates of radiological progression and decline in pulmonary during follow-up were 63% and 39%, respectively. During follow-up, all patients were diagnosed with silicosis. All workers who were ILO category 0 at baseline (n = 26, 29%) progressed to higher categories. The number of patients in Category 2 doubled and the number of patients in Category 3 increased by 2.5-fold. Eleven patients developed new large opacities and the number of patients with category C opacity increased from 4 to 13. selleck compound Exposure time was an independent determinant of radiological progression (OR 1.0, P = 0.036) and decline in pulmonary function (OR 1.3, P = 0.019).

The prevalence of silicosis in denim sandblasters increases steadily even after exposure is discontinued. Radiological progression was observed in a higher proportion of workers than a decline in lung function. Duration of exposure was the major determinant of disease progression in our study.

As such, we know very little about the number of species present, nor the evolutionary forces responsible for generating this diversity. One hypothesis is that trait diversity in the gall wasps, including the morphology of the galls they induce, has evolved in response to selection imposed by the parasitoid community, with reciprocal selection driving diversification of the parasitoids. Using a rare, continental-scale data set of Sycophila parasitoid wasps reared from 44 species of cynipid galls from 18 species of oak across the USA, we combined mitochondrial DNA barcodes, ultraconserved elements (UCEs), morphological and natural history data to delimit putative species. Using these results, we generate the first large-scale assessment of ecological specialization and host association in this species-rich group, with implications for evolutionary ecology and biocontrol. We find most Sycophila target specific subsets of available cynipid host galls with similar morphologies, and generally attack larger galls. Our results suggest that parasitoid wasps such as Sycophila have adaptations allowing them to exploit particular host trait combinations, while hosts with contrasting traits are resistant to attack. These findings support the tritrophic niche concept for the structuring of plant-herbivore-parasitoid communities.Portable gas exchange analysers provide critical data for understanding plant-atmosphere carbon and water fluxes, and for parameterising Earth system models that forecast climate change effects and feedbacks. We characterised temperature measurement errors in the Li-Cor LI-6400XT and LI-6800, and estimated downstream errors in derived quantities, including stomatal conductance (gsw ) and leaf intercellular CO2 concentration (Ci ). The LI-6400XT exhibited air temperature errors (differences between reported air temperature and air temperature measured near the leaf) up to 7.2°C, leaf temperature errors up to 5.3°C, and relative errors in gsw and Ci that increased as temperatures departed from ambient. This caused errors in leaf-to-air temperature relationships, assimilation-temperature curves and CO2 response curves. Temperature dependencies of maximum Rubisco carboxylation rate (Vcmax ) and maximum RuBP regeneration rate (Jmax ) showed errors of 12% and 35%, respectively. These errors are likely to be idiosyncratic and may differ among machines and environmental conditions. The LI-6800 exhibited much smaller errors. Earth system model predictions may be erroneous, as much of their parametrisation data were measured on the LI-6400XT system, depending on the methods used. We make recommendations for minimising errors and correcting data in the LI-6400XT. We also recommend transitioning to the LI-6800 for future data collection.The first water-soluble B-ring-indole-substituted flavonol-based cysteine (Cys) fluorescent probe, MICA (2-(1-methyl-1H-indol-3-yl)-4-oxo-4H-chromen-3-yl-acrylate), was developed, which simultaneously serves as a precursor of photoCORM. In PBS buffer (only 15% DMF), MICA can perform rapid (330 s), highly chemoselective (particularly for homocysteine and glutathione) and sensitive (limit of detection 92 nM) sensing and visualization of exogenous and endogenous Cys in live HeLa cells and zebrafish over a wide linear concentration range (0-12 μM/2.4 equiv.). The fluorophore HMIC (3-hydroxy-2-(1-methyl-1H-indol-3-yl)-4H-chromen-4-one), actuated and quantitatively generated via the sensing reaction of the precursor MICA with Cys, was designed as a photoCORM. By modulating the light illumination intensity or illumination duration or photoCORM dosage, HMIC can provide precisely controlled quantitative and linear CO gas by visible light illumination in aerobic environments. For live HeLa cells, MICA and all reaction for clinical diagnosis and CO gas therapy.
Healthcare research, planning, and delivery with minimal community engagement can result in financial wastage, failure to meet objectives, and frustration in the communities that programmes are designed to help. Engaging communities - individual service-users and user groups - in the planning, delivery, and assessment of healthcare initiatives from inception promotes transparency, accountability, and 'ownership'. Health systems affected by conflict must try to ensure that interventions engage communities and do not exacerbate existing problems. Engaging communities in interventions and research on conflict-affected health systems is essential to begin addressing effects on service delivery and access.

This review aimed to identify and interrogate the literature on community engagement in health system interventions and research in conflict-affected settings.

We conducted a scoping review using Arksey & O'Malley's framework, synthesising the data descriptively.

We included 19 of 2,355 potential soue particularly difficult in conflict-affected settings, where priorities may not be easy to identify, and many other factors, such as safety, power relations, and entrenched inequalities, must be considered.
Community engagement in identifying and setting priorities, decision-making, implementing, and evaluating potential solutions helps people share their views and encourages a sense of ownership and increases the likely success of healthcare interventions. However, engaging communities can be particularly difficult in conflict-affected settings, where priorities may not be easy to identify, and many other factors, such as safety, power relations, and entrenched inequalities, must be considered.
