The influence of transpiration on foliar accumulation of salt and nutrients under salinity in poplar (Populus × canescens)

Increasing salinity is one of the major drawbacks for plant growth. Besides the ion itself being toxic to plant cells, it greatly interferes with the supply of other macronutrients like potassium, calcium and magnesium. However, little is known about how sodium affects the translocation of these nutrients from the root to the shoot. The major driving force of this translocation process is thought to be the water flow through the xylem driven by transpiration. To dissect the effects of transpiration from those of salinity we compared salt stressed, ABA treated and combined salt- and ABA treated poplars with untreated controls. Salinity reduced the root content of major nutrients like K+, Ca2+ and Mg2+. Less Ca2+ and Mg2+ in the roots resulted in reduced leaf Ca2+ and leaf Mg2+ levels due to reduced stomatal conductance and reduced transpiration. Interestingly, leaf K+ levels were positively affected in leaves under salt stress although there was less K+ in the roots under salt. In response to ABA, transpiration was also decreased and Mg2+ and Ca2+ levels decreased comparably to the salt stress treatment, while K+ levels were not affected. Thus, our results suggest that loading and retention of leaf K+ is enhanced under salt stress compared to merely transpiration driven cation supply.
Lower-Extremity Segment-Length Prediction Accuracy of the Sanders Multiplier, Paley Multiplier, and White-Menelaus Formula

Background: Several methods are available to estimate leg lengths at maturity to facilitate the determination of timing of epiphysiodesis. We compared the Paley multiplier, Sanders multiplier, and White-Menelaus methods in an epiphysiodesis-aged cohort. We assessed intra- and interrater reliability for Sanders skeletal stages and Greulich and Pyle atlas skeletal age. Methods: Actual growth was recorded in healthy, unoperated femoral and tibial segments from an epiphysiodesis database. The predicted and actual lengths were compared with use of the Paley multiplier and White-Menelaus methods, Greulich and Pyle skeletal age, and the Sanders multiplier using Sanders stages. Intra- and interrater reliability were assessed in a separate group of 76 skeletal age films. Results: The cohort included 148 femora and 195 tibiae in 197 patients. Femoral length at maturity was slightly underestimated by the Sanders multiplier and staging, was overestimated by the Paley multiplier and skeletal age, and was most accurately predicted with use of the White-Menelaus formula and skeletal age. All methods overestimated tibial length at maturity. The whole-leg prediction accuracy of the Sanders multiplier and White-Menelaus formula were comparable and were more accurate than that of the Paley multiplier. For Sanders skeletal staging, the interrater reliability varied from 0.86 to 0.88 and the intrarater reliability varied from 0.87 to 0.96. For Greulich and Pyle skeletal age, the interrater reliability varied from 0.87 to 0.89 and the intrarater reliability varied from 0.91 to 0.95. Conclusions: Use of the Sanders multiplier and skeletal stages was more accurate than the Paley multiplier and skeletal age in this cohort. Use of the White-Menelaus formula and skeletal age was slightly more accurate in predicting femoral length and slightly less accurate in predicting tibial length compared with the Sanders multiplier. Intra- and interrater reliability were similar between Sanders skeletal stages and Greulich and Pyle atlas skeletal age. The White-Menelaus formula and skeletal age was the recommended method for predicting lower-extremity segment lengths at maturity and epiphysiodesis effect. Although easier to recall without referencing an atlas and not sex-specific, Sanders skeletal staging does not correspond directly to years of growth remaining, and thus cannot be used with the White-Menelaus formula. Clinical Relevance: The Greulich and Pyle atlas to determine skeletal age and the White-Menelaus formula to determine growth remaining are reliable predictors of epiphysiodesis effect in the lower extremities.
Development of a cortical delay discounting assay: a potential biomarker of externalizing disorders

Abstract Background People who tend to impulsively choose smaller, sooner rewards over larger, later rewards are at increased risk for addiction and psychiatric disorders. A neurobiological measure of the tendency to overvalue immediate gratification could facilitate the study of individuals who are susceptible to these mental disorders. The objective of this research was to develop a cortical assay of impulsive choice for immediate rewards. Methods A cortex-based assay of impulsive choice was developed using 1105 healthy adults from the Human Connectome Project, and then cross-validated in two independent samples of adults with elevated rates of psychiatric disorders. Results Study 1: Cortical delay discounting (C-DD) was developed using a multivariate additive model of gray matter thickness across both hemispheres. Higher C-DD corresponded to thinner cortex and greater impulsive choice for immediate rewards. It also predicted cannabis use beyond established risk factors for drug use, including familial substance use, childhood conduct problems, personality traits, and cognitive functioning. Study 2: C-DD replicated the association with delay discounting performance from study 1. Structural equation modeling showed C-DD covaried with symptoms of externalizing, but not internalizing disorders. Study 3: C-DD positively predicted future delay discounting behavior (6–34 months later). Conclusions Across three studies, a cortical assay of impulsive choice evidenced consistent associations with drug use and delay discounting task performance. It was also uniquely associated with psychiatric disorders that share impulsivity as a core feature. Together, findings support the utility of C-DD as a neurobiological assay of impulsive decision-making and a possible biomarker of externalizing disorders.
Perceived Stress Predicts Subsequent Self-Reported Problems With Vision and Hearing: Longitudinal Findings From the German Ageing Survey

Although stress is a risk factor for various diseases in later life, its role for sensory abilities in the second half of life has rarely been empirically addressed. We examined if perceived stress at baseline predicts self-reported difficulties with vision and hearing 3 years later. We also explored whether chronological age is a moderator of associations between stress and sensory difficulties. Our sample was derived from the German Ageing Survey and consisted of n = 5,085 individuals aged 40–95 years (M = 64.01 years, SD = 10.84 years). Controlling for baseline self-reported sensory functioning, socio-demographic indicators, self-rated health and chronic diseases, greater perceived stress at baseline predicted greater self-reported difficulties with vision and hearing 3 years later. The effect of stress did not vary by age. Our findings suggest that, from middle adulthood to advanced old age, stress is a risk factor for increases in self-perceived problems with vision and hearing.
Health-related quality of life of COPD patients aged over 40 years.

Background Chronic obstructive pulmonary disease (COPD) is the fourth most frequent disease globally, and its worldwide prevalence is projected to increase in the following decades. Health-related quality of life (HRQOL) of COPD patients depends on multiple factors. Objective The aim of this study was to identify the most important risk factors affecting HRQOL of COPD patients and to measure how specific clinical parameters can predict HRQOL. Methods A questionnaire-based cross-sectional study combined with clinical data was conducted among patients diagnosed with COPD (n = 321, 52.6% females, mean age 66.4 ± 9.5) at the National Koranyi Institute for Pulmonology, Budapest in 2019-2020. The inclusion criteria were age ≥40 years and existing COPD. Multivariate linear regression analyses were conducted on three components of the COPD-specific Saint George's Respiratory Questionnaire (SGRQ-C) and on the physical (PCS) and mental component scales (MCS) of the 36-Item Short Form Health Survey (SF-36). Multiple linear regression analysis was performed to evaluate the effects of patient and disease characteristics on COPD Assessment Test (CAT) scores. Results We found that frequent exacerbations, multiple comorbidities and tobacco smoking were associated with worse HRQOL. Engaging in more frequent physical activity and better 6-minute walking distance results were associated with better HRQOL. Conclusions Our results indicate that the complex therapy of COPD should focus not only on improving lung functions and preventing exacerbation, but also on treating comorbidities, encouraging increased physical activity, and supporting smoking cessation to assure better HRQOL for patients.
Neutralizing Monoclonal Antibody Treatment Reduces Hospitalization for Mild and Moderate COVID-19: A Real-World Experience

Abstract Background Neutralizing monoclonal antibody (NmAb) treatments have received emergency use authorization to treat patients with mild or moderate COVID-19 infection. To date, no real- world data about the efficacy of NmAb has been reported from clinical practice. We assessed the impact of NmAb treatment given in the outpatient clinical practice setting on hospital utilization. Methods Electronic medical records were used to identify adult COVID-19 patients who received NmAbs [bamlanivimab (BAM) or casirivimab and imdevimab (REGN-COV2)] and historic COVID-19 controls. Post-index hospitalization rates were compared. Results 707 confirmed COVID-19 patients received NmAb and 1709 historic COVID-19 controls were included; 553 (78%) received BAM, 154 (22%) received REGN-COV2. Patients receiving NmAb infusion had significantly lower hospitalization rate (5.8% vs. 11.4%, p<0.0001); a shorter length of stay if hospitalized (mean 5.2 days vs. 7.4 days, p=0.02), and fewer ED visits within 30 days post-index (8.1% vs 12.3%, p=0.003) than controls. Hospitalization-free survival was significantly longer in NmAb patients compared to controls (p<0.0001). There was a trend towards a lower hospitalization rate among patients who received NmAb within 2-4 days after symptom onset. In multivariate analysis, having received a NmAb transfusion was independently associated with a lower risk of hospitalization after adjustment for age, sex, race, BMI and referral source: adjusted hazard ratio (95% CI) = 0.54 (0.38 – 0.79), p=0.0012. Overall mortality was not different between the two groups. Conclusions and Relevance NmAb treatment reduced hospital utilization especially when received within a few days of symptom onset. Further study is needed to validate these findings.
Can the native faunal communities be restored from removal of invasive plants in coastal ecosystems? A global meta‐analysis

Coastal ecosystems worldwide are being threatened by invasive plants in the context of global changes. However, how invasive plants influence native faunal communities and whether native faunal communities can recover following the invader removals/controls across global coastal ecosystems are still poorly understood. Here, we present the first global meta‐analysis to quantify the impacts of Spartina species invasions on coastal faunal communities and further to evaluate the outcomes of Spartina species removals on faunal community recovery based on 74 independent studies. We found that invasive Spartina species generally decreased the biodiversity (e.g., species richness), but increased coastal faunal abundance (e.g., individual number) and fitness (e.g., biomass), though the effect on abundance was insignificant. The pattern of influence was strongly dependent on habitat types, faunal taxa, trophic levels, and feeding types. Specifically, Spartina species invasion of mudflats caused greater impacts than invasion of vegetated habitats. Insects and birds at higher trophic levels were strongly affected by invasive Spartina, indicating that invasive plant effects can cascade upward along the food chain. Additionally, impacts of Spartina invasions were more obvious on food specialists such as herbivores and carnivores. Furthermore, our analyses revealed that invader removals were overall beneficial for native faunal communities to recover from the displacement caused by Spartina invasions, but this recovery process depended on specific removal measure and time. For example, the long‐term waterlogging had strong negative impacts on faunal recovery, so it should not be encouraged. Our findings suggest that invasive plants could have contrasting effects on functional responses of native faunal communities. Although invasive plant removals could restore native faunal communities, future functional restorations of invaded ecosystems should take the legacy effects of invasive species on native communities into account. These findings provide insightful implications for future scientific controls of invasive species and ecosystem restoration under intensifying global changes.
Correlation Between QElaXto Techniques and Supersonic Imagine for Liver Stiffness Quantification in Chronic Liver Disease

Intersystem variability in liver stiffness (LS) quantification with ultrasound shear wave elastography (SWE) precludes direct comparison of results obtained with different equipment. The aim of this study was to investigate the agreement between point‐SWE and 2‐dimensional‐SWE with Esaote‐MyLab 9 (p‐QElaXto and 2D‐QElaXto, respectively) and 2D‐SWE with SuperSonic Imagine (SSI) in order to assess specific LS thresholds for fibrosis staging with QElaXto techniques, using SSI as a reference standard.
Effects of dual-task interference on swallowing in healthy aging adults

A wide body of literature has demonstrated that the neural representation of healthy swallowing is mostly bilateral, with one hemisphere dominant over the other. While several studies have demonstrated the presence of laterality for swallowing related functions among young adults, the data on older adults are still growing. The purpose of this paper is to investigate potential changes in hemispheric dominance in healthy aging adults for swallowing related tasks using a behavioral dual-task paradigm. A modified dual-task paradigm was designed to investigate the potential reduction in hemispherical specialization for swallowing function. Eighty healthy right-handed participants in the study were divided into two groups [Group 1: young adults (18–40 years) and Group 2: older adults (65 and above)]. All the participants performed a timed water swallow test at baseline and with two interference conditions (silent word repetition, and facial recognition). The results of the study revealed the following 1) a statistically significant effect of age on swallow performance; 2) statistically significant effect of each of the interference tasks on two of the swallow measures (VPS and VPT) in younger adults; and 3) no significant effect of the interference tasks on the swallowing performance of older adults. These findings suggest that aging substantially affects swallowing in older individuals, and this potentially accompanies a reduction in the hemispheric specialization for swallowing related tasks.
Surgical treatment of peri-implantitis with or without a deproteinized bovine bone mineral and a native bilayer collagen membrane. A randomized clinical trial.

AIM To assess whether the use of deproteinized bovine bone mineral (DBBM) and native bilayer collagen membrane (NBCM) improved healing of peri-implantitis-related bone defects at 12 months. MATERIALS AND METHODS In a multicentre randomized clinical trial, 32 individuals received surgical debridement (CG), and 34 adjunct use of DBBM and NBCM (TG). Radiographic defect fill (RDF), probing pocket depth (PPD), bleeding on probing (BOP) suppuration (SUP), recession (REC), cytokines (IL-1β, IL-1ra, IL-6, IL-8, IL-12, IP10, PDGF-BB, TNF-α, VEGF), and patient-reported outcomes (PROs) were evaluated at 3, 6, 9 and 12 months. RESULTS RDF at deepest site amounted 2.7 ± 1.3 mm in TG and 1.4 ± 1.2 mm in CG (p < 0.0001). PPD was reduced by 1.9 mm in TG and 2.3 mm in CG (p =0.5783). There were no significant differences between groups regarding reductions of BOP, SUP, REC, cytokines levels, or OHIP 14 scores at 12 months. Successful treatment (RDF ≥1.0 mm, PPD ≤5 mm, ≤1/4 site with BOP grade 1, no SUP) were identified in 32% in TG and 21 % in CG. CONCLUSIONS DBBM and NBCM resulted in significantly more RDF than debridement alone. No difference was found in any clinical parameters or PROs between groups.
Additional Value of Peer Informants in Psychological Autopsy Studies of Youth Suicides

In this study, we examined the feasibility and added value of including peer informants in a psychological autopsy study of youth suicides. Peer semi-structured interview data from 16 cases were analyzed qualitatively and compared to parent data. Results show that peers added information to parents’ narratives in general and particularly on social relationships, bullying, school experiences, social media, and family relations. Peers also provided additional information on the presence of certain issues (such as social media contagion) as well as on the emotional impact from certain adverse events that seemed to have functioned as precipitating factors. We conclude that including peers in psychological autopsy studies of youth suicides is feasible and of added value but that more research is desirable. The results initially can be used in the design of psychological autopsies so that the maximum amount of information about each suicide will be learned.
Evaluating Very Deep Convolutional Neural Networks for Nucleus Segmentation from Brightfield Cell Microscopy Images

Advances in microscopy have increased output data volumes, and powerful image analysis methods are required to match. In particular, finding and characterizing nuclei from microscopy images, a core cytometry task, remains difficult to automate. While deep learning models have given encouraging results on this problem, the most powerful approaches have not yet been tested for attacking it. Here, we review and evaluate state-of-the-art very deep convolutional neural network architectures and training strategies for segmenting nuclei from brightfield cell images. We tested U-Net as a baseline model; considered U-Net++, Tiramisu, and DeepLabv3+ as latest instances of advanced families of segmentation models; and propose PPU-Net, a novel light-weight alternative. The deeper architectures outperformed standard U-Net and results from previous studies on the challenging brightfield images, with balanced pixel-wise accuracies of up to 86%. PPU-Net achieved this performance with 20-fold fewer parameters than the comparably accurate methods. All models perform better on larger nuclei and in sparser images. We further confirmed that in the absence of plentiful training data, augmentation and pretraining on other data improve performance. In particular, using only 16 images with data augmentation is enough to achieve a pixel-wise F1 score that is within 5% of the one achieved with a full data set for all models. The remaining segmentation errors are mainly due to missed nuclei in dense regions, overlapping cells, and imaging artifacts, indicating the major outstanding challenges.
Chemical Diversity and Antioxidant Capacity of Essential Oils of Marjoram in Northwest Egypt

Abstract Origanum majorana “Marjoram” cultivation in Egypt dates back to 3000BC with current global distribution and economic importance in medicinal and herbal products. Plant natural diversity and scattered cultivated populations may harbor chemical diversity useful in agricultural and pharmaceutical industries. To investigate this assumption in Northwest Egypt, leaves essential oil (EO) composition of local accessions of Origanum majoranaL. are examined and in comparison in this study. Antioxidant activities (AA) using both of 2,2′-diphenypicrylhydrazyl (DPPH) and β-carotene-linoleic acid assay were examined for EOs. Main EOs constituent were cis-sabinene hydrate 34.3 %, α-terpinen 18 %, 4-terpineol 15.20 %, terpinolene 11.8 %, and sabinene 7.4 %; α-terpinen 29.2 %, cis-sabinene hydrate 15.40 %, terpinolene 19.50 %, and 4-terpineol 14.40 %; 4-terpineol 35 %, cis-sabinene hydrate 20 %, terpinolene 10.33 %, α-terpinen 8.96 %, and sabinene 8.4 % in the accessions OM550, OM555 and OM560; respectively. Examined accessions were classified into two chemotypes easily using their Eos harboring either sabinene or terpinens as major constituents. High antioxidant capacities were related to high sabinene and terpinens contents. It was concluded that Egyptian marjoram harbor good quality essential oils could be utilized as food additives and for improving human health.
Simultaneous Use of Hypertonic Saline and IV Furosemide for Fluid Overload: A Systematic Review and Meta-Analysis

Supplemental Digital Content is available in the text. OBJECTIVES: To evaluate the efficacy of the simultaneous hypertonic saline solution and IV furosemide (HSS+Fx) for patients with fluid overload compared with IV furosemide alone (Fx). DATA SOURCES: Electronic databases (MEDLINE, EMBASE, CENTRAL, Cochrane Database of Systematic Reviews, PsycINFO, Scopus, and WOS) were searched from inception to March 2020. STUDY SELECTION: Randomized controlled trials on the use of HSS+Fx in adult patients with fluid overload versus Fx were included. DATA EXTRACTION: Data were collected on all-cause mortality, hospital length of stay, heart failure–related readmission, along with inpatient weight loss, change of daily diuresis, serum creatinine, and 24-hour urine sodium excretion from prior to post intervention. Pooled analysis with random effects models yielded relative risk or mean difference with 95% CIs. DATA SYNTHESIS: Eleven randomized controlled trials comprising 2,987 acute decompensated heart failure patients were included. Meta-analysis demonstrated that HSS+Fx was associated with lower all-cause mortality (relative risk, 0.55; 95% CI, 0.46–0.67; p < 0.05; I2 = 12%) and heart failure–related readmissions (relative risk, 0.50; 95% CI, 0.33–0.76; p < 0.05; I2 = 61%), shorter hospital length of stay (mean difference, –3.28 d; 95% CI, –4.14 to –2.43; p < 0.05; I2 = 93%), increased daily diuresis (mean difference, 583.87 mL; 95% CI, 504.92–662.81; p < 0.05; I2 = 76%), weight loss (mean difference, –1.76 kg; 95% CI, –2.52 to –1.00; p < 0.05; I2 = 57%), serum sodium change (mean difference, 6.89 mEq/L; 95% CI, 4.98–8.79; p < 0.05; I2 = 95%), and higher 24-hour urine sodium excretion (mean difference, 61.10 mEq; 95% CI, 51.47–70.73; p < 0.05; I2 = 95%), along with decreased serum creatinine (mean difference, –0.46 mg/dL; 95% CI, –0.51 to –0.41; p < 0.05; I2 = 89%) when compared with Fx. The Grading of Recommendation, Assessment, Development, and Evaluation certainty of evidence ranged from low to moderate. CONCLUSIONS: Benefits of the HSS+Fx over Fx were observed across all examined outcomes in acute decompensated heart failure patients with fluid overload. There is at least moderate certainty that HSS+Fx is associated with a reduction in mortality in patients with acute decompensated heart failure. Factors associated with a successful HSS+Fx utilization are still unknown. Current evidence cannot be extrapolated to other than fluid overload states in acute decompensated heart failure.
