Stream thermal regimes are critical to the stability of freshwater habitats. There is growing concern that climate change will result in stream warming due to rising air temperatures, decreased shading in forested areas due to wildfires, and changes in streamflow. Groundwater plays an important role in controlling stream temperatures in mountain headwaters, where it makes up a considerable portion of discharge. This study investigated the controls on the thermal regime of a headwater stream, and the surrounding groundwater processes, in a catchment on the eastern slopes of the Canadian Rocky Mountains. Groundwater discharge to the headwater spring is partially sourced by a seasonal lake. Spring, stream, and lake temperature, water level, discharge and chemistry data were used to build a conceptual model of the system. Meteorological data was used to set up a stream temperature model. A tracer test was carried out to estimate hyporheic exchange along the study reach. This study presents a unique example of an indirectly lake-headed stream i.e., where the interaction of groundwater and lake water, and the hydraulic gradient determine the resulting stream temperature. Energy balance of the stream is mainly controlled by radiation. Sensible and latent heat fluxes play a secondary role, but their effects generally cancel out. Hyporheic exchange is present but plays only a minor role in the energy balance. During snowfall events, the latent heat associated with melting of direct snowfall onto the water surface was responsible for rapid stream cooling. An increase in advective inputs from groundwater and hillslope pathways did not result in observed cooling of stream water during rainfall events. The results from this study will assist water resource and fisheries managers in adapting to stream temperature changes under a warming climate.

Background: Chemotherapy-induced cardiotoxicity (ChC) is an important complication among patients receiving anthracyclines. Biomarkers and imaging parameters have been studied for their ability to identify patients at risk of developing this complication. Left ventricle global longitudinal strain (LV-GLS) has been described as a sensitive parameter for detecting systolic dysfunction, even in the presence of preserved left ventricle ejection fraction (LVEF). Objective: to evaluate the role of the LV-GLS as a predictor of ChC. Methods: This study is a post-hoc analysis of CECCY trial (Carvedilol for Prevention of Chemotherapy-Related Cardiotoxicity) that evaluated the primary prevention of cardiotoxicity with carvedilol during doxorubicin chemotherapy in a population with breast cancer. Cardiotoxicity was defined as a reduction >10% in LVEF. LV-GLS was obtained before chemotherapy in patients with no prior cardiovascular disease or echocardiogram abnormalities. Results: Thirty-one patients who had a complete echocardiography study including measurement of LV-GLS before chemotherapy were included in this analysis. An absolute LV-GLS <16.9% before chemotherapy showed 100% sensitivity and 73% specificity for predicting cardiotoxicity (AUC=0.85; 95%CI 0.680 – 0.959, p<0.001). In this population, LVEF values before chemotherapy did not predict ChC (95%CI 0.478 to -0.842, p=0.17). The association of low LV-GLS (<17%) and BNP serum levels (>17 pg/mL) two months after chemotherapy increased the accuracy for detecting early onset ChC (100% sensitivity, 88% specificity, AUC=0.94; 95%CI 0.781 – 0.995, p<0.0001). Conclusions: Our data suggest that LV-GLS is a potential predictor of chemotherapy-induced cardiotoxicity. Larger studies are needed to confirm the relevance of this echocardiographic parameter in this clinical setting.

Objective: Inhaled corticosteroids (ICS) are recommended by the Global Initiative for Asthma for the treatment of steps 2-3 childhood asthma. However, the difference in efficacy between these different ICS drugs is not clear. The main purpose of this study was to compare the efficacy of different ICS drugs in the treatment of childhood asthma and to provide effective quantitative information for guiding their use. Methods: We searched PubMed and EMBASE for randomized controlled trials of ICS in the treatment of childhood asthma. Using forced expiratory volume in the first second (FEV1) as the efficacy index, a time-course model of ICS drugs was constructed. Related influencing factors were also investigated. Important pharmacodynamic parameters, such as maximum efficacy and onset time of each ICS, were calculated to reflect their differences in efficacy characteristics. Results: A total of 6 studies involving 2237 children were analyzed, including five arms of BUD (456 subjects), three arms of CIC (876 subjects), two arms of FP (352 subjects), one arm of MF (197 subjects), and three arms of FF (356 subjects). Since the study was limited by the data collected, pharmacodynamic models could only be constructed for BUD and CIC. The results showed that there was no significant difference in the maximum efficacy between BUD and CIC, and that the Emax values of the percentage change in FEV1 were 17.4 (95% CI: 16.9, 17.9)%. The ET50 of CIC and BUD was 1.23 (95% CI: 0.76, 1.70) weeks and 2.97 (95% CI: 1.8, 4.14) weeks, respectively. Compared with the 95% confidence intervals of BUD and CIC, FP had the highest efficacy, MF had the lowest efficacy, and the efficacy of FF was comparable to that of BUD and CIC. Conclusion: In this study, the efficacy of five ICS drugs was quantitatively compared, providing necessary information for the implementation of medication guidelines for steps 2-3 asthma in children.

Infectious complications after percutaneous transluminal coronary angioplasty are uncommon and can occur at any point of time leading to high morbidity and mortality. We report a case of delayed coronary artery stent infection and rupture, with epicardial infected false aneurysm formation, and right coronary artery to right atrium fistula formation, presenting after one month of pyrexia.

Background: The nonclassic presentation of pediatric celiac disease (CD) becomes increasingly common in daily practice, which requires an awareness of its extraintestinal clinical findings. To evaluate eye involvement and effect of gluten free diet on ocular involvement in pediatric CD patients by measuring the thicknesses of choroid and ganglion cell complex(GCC) composed of retinal nerve fiber layer (RNFL), ganglion cell layer (GCL) and inner plexiform layer (IPL) using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: Forty-three CD patients aged between four and 16 years (mean age;9.9 ± 4.1, 12 boys and 31 girls), and 48 healthy children (mean age; 11.3 ± 4.1,17 boys and 31 girls) were compared. Following comprehensive eye examinations, thicknesses of choroid at three points and GCC layers (RNFL at five points, GCL and IPL) were obtained using EDI-OCT. Measurement of thicknesses of choroid and GCC layers by a trained EDI-OCT technician and an ophthalmologist who were not aware about group of children in pediatric CD patients with one year gluten free diet. Results: All layers of subfoveal, nasal, temporal choroid were significantly thinner in CD than in the control group (p < .001, p < .001, and p < .001, respectively). No significant difference were observed between the CD and control groups in terms of GCC thicknesses (p > .05). Conclusion: Pediatric CD causing thinning of subfoveal, nasal and temporal areas of choroid, and this change is apparent even after one year gluten free diet. This extraintestinal involvement should be more closely screened at diagnosis and long term clinical results of thin choroid should be determined. Thicknesses of GCC layers were not different in CD group may be revealing the effect of diet or not involvement.

Modern bread wheat has a huge genetic potential to adjust its heading date with favorable conditions that has remained largely unexplored so far. In this study, we used an association panel of in Germany adapted cultivars that was tested in multi-location field trials across Germany over three years. The genotypic response to climatic parameters variation depending on location and year uncovered the implication of photoperiod in promoting transition to flowering in higher latitudes, while spring temperature accelerates flowering in lower ones. Spring temperature overdominates other factors in decreasing the days to heading whereas the higher amount of solar radiation is delaying it. Genome wide scan detected a so far unknown stable locus TaHd14 on chromosome 5A. Including non-adapted cultivars, the exotic allele TaHd119 on chromosome 3A could be identified. The later explains up to 33% of the genetic variance and accelerates heading date by 5.63 days. The response to the competition of latitude dependent climatic variables detected fine tuning QTL responding to temperature and photoperiod in lower and higher latitudes, respectively. A novel locus TaHd12 on chromosome 5A showed significant epistatic interactions with 15 known operators of HD regulation when exotic cultivars were included in the analysis

The purpose of this article is to study and investigate statistically probability convergence for the sequence of random variables by virtue of deferred N\“{o}rlund and deferred Euler summability mean. With the aid of MATLAB software, we also graphically exhibits the statistically probability convergence for probability density function of random variables. Further, as an application of our newly form summability mean, we prove Korovkin type approximation theorem via deferred N\”{o}rlund and deferred Euler statistically probability convergence and present compelling instances to illustrate the findings.

Brucellosis is an infectious bacterial disease that mainly affects ruminants and humans and its detection is still a significant challenge in particular, in the developing countries. At present, methods used to diagnose brucellosis consist of microbiological, biochemical, immunological, and molecular techniques which may be time-consuming, laborious, expensive, and dependent on special equipment, while they may not be suitable for on-site miniaturized detection. Thus, development of novel methods that can characterize Brucella spp with minimal equipment is invaluable for rapid and easy detection of these pathogenic bacteria especially in basic laboratories or even in the farm fields. The nanotechnology-driven approach can be successfully applied using different nanoparticles for the diagnosis of pathogens. Nanobiosensors are therefore, one of those promising solutions in this case. These sensors are efficient tools with diverse biological applications which can identify pathogenic bacteria with relatively high sensitivity and specificity. In this context, new nanobiosensors, developed based on various nanoparticles, for rapid detection of Brucella spp have been discussed.

We report here an assessment of the model refinement category of the 14th round of Critical Assessment of Structure Prediction (CASP14). As before, predictors submitted up to five ranked refinements, along with associated residue-level error estimates, for targets that had a wide range of starting quality. The ability of groups to accurately rank their submissions and to predict coordinate error varied widely. Overall only four groups out-performed a “naïve predictor” corresponding to resubmission of the starting model. Among the top groups there are interesting differences of approach and in the spread of improvements seen: some methods are more conservative, others more adventurous. Some targets were “double-barrelled” for which predictors were offered a high-quality AlphaFold 2 (AF2)-derived prediction alongside another of lower quality. The AF2-derived models were largely unimprovable, their apparent errors being found to reside very largely at domain and, especially, crystal lattice contacts. Refinement is shown to have a mixed impact overall on structure-based function annotation methods to predict nucleic acid binding, spot catalytic sites and dock protein structures.

Signatures of past changes in population size have been detected in genome-wide variation in many species. However, the causes of such demographic changes and the extent to which they are shared across co-distributed species remain poorly understood. During Pleistocene glacial maxima, many temperate European species were confined to southern refugia. While vicariance and range expansion processes associated with glacial cycles have been widely studied, little is known about the demographic history of refugial populations, and the extent and causes of demographic variation among co-distributed species. We used whole genome sequence data to reconstruct and compare demographic histories during the Quaternary for Iberian refuge populations in a single ecological guild (seven species of chalcid parasitoid wasps associated with oak cynipid galls). We find support for large changes in effective population size through the Pleistocene that coincide with major climate events. However, there is little evidence that the timing, direction and magnitude of demographic change are shared across species, suggesting that demographic histories are largely idiosyncratic even at the scale of a single glacial refugium.

Objective: To assess the acceptability, safety and efficacy of the PPH Butterfly, a new uterine compression device, in women with postpartum haemorrhage (PPH). Design: A phase two clinical device trial using matched historical controls, with accompanying grounded theory study. Setting: UK university consultant obstetric unit. Population: women with PPH after vaginal birth unresponsive to initial oxytocin therapy. Outcomes were compared to historical controls matched on blood loss, parity and type of birth. Methods: after oral consent, trained staff used the device in additional to normal care. Main Outcome Measures: The primary outcome was additional blood loss >1000mls. Qualitative interviews assessed device feasibility and acceptability. Results: Of the 57 recruits, two-thirds were primiparous and almost half had undergone operative birth. Two percent of recruited women had additional blood loss of over 1000mls compared to 8% of 113 controls (adjusted odds ratio 0.13, 95% CI (0.02 to 1.09)). Women treated with the device received significantly more additional treatments and had higher rates of exclusive breast-feeding at discharge. There were no serious adverse events related to the device. In 47 interviews, participants, birth partners, clinicians and attending midwives viewed the device positively. Clinicians found it useful to stop blood loss and diagnose the source of bleeding. Conclusions: the PPH Butterfly is acceptable and may have clinical benefits: it is a promising device for PPH management.

Secondly, Existence of the Aboodh transform proved. Then, the two linear delay differential equations are solved by Aboodh transform. This means that Aboodh transform is a powerful tool for solving linear delay differential equations.

Carbon nanotubes (CNTs) have excellent catalytic activity in liquid phase reaction, especially in aerobic oxidation of cumene. In previous work, the conversion of cumene was 41.8% and the selectivity of cumene hydroperoxide was 71.5%, which was catalyzed by CNTs. But a small amount of impurity Zn2+ totally blocked up the aerobic oxidation of cumene that catalyzed by CNTs, which is an unexpected discovery. By analyzing the catalytic mechanism of CNTs, the inhibition effect of Zn2+ is locked on the abstraction of H atom from cumene. The inhibition of Zn2+ is confirmed in two effects by density functional theory (DFT) calculations. Firstly, due to the strongly coordination of active oxygen species (ROS) by Zn2+, the energy barrier of initial reaction increases to 1.90 eV, which is nearly 4 times higher than that of the only ROS promoted-process. Secondly, the interaction of Zn2+ and RO· or ROO· to inhibits the chain propagation reaction of free radicals. This work precisely demonstrates that the inhibition effect of Zn2+ on initial reaction of cumene. The most significant thing is that the effect of metallic heteroatoms is not negligible in organic oxidation reaction.

• Telephone interviews were conducted with 19 MACRO trial participants from 5 ENT sites across the UK. • Trial participants experienced mixed levels of communication during the COVID period and some felt uninformed about the trial status and their clinical situation. • Participants were most concerned about getting COVID through interactions with other patients in hospital settings. Conversely, there was a high level of trust in healthcare professionals. • Pre-visit COVID-safety information, minimising contact with other patients, and strict waiting room management can facilitate the restart of the MACRO trial from the patient perspective. • Patient confidence in trial participation is likely to continue improving with COVID vaccination roll out.

1. The use of a drone to count the flock sizes of 33 species of waterbirds during the breeding and non-breeding periods was investigated. 2. In 96% of 343 cases, drone counting was successful. 18.8% of non-breeding birds and 3.6% of breeding birds exhibited adverse reactions: in the former, the birds were flushed, whereas the latter attempted to attack the drone. 3. The automatic counting birds was best done with the microbiology software - ImageJ / Fiji: the average bird counting rate was 100 birds in 82 seconds. 4. Machine learning using neural network algorithms proved to be an effective and fast way of counting birds – 100 birds in 23 seconds. However, as the preparation of images and machine learning time are time-consuming, this method is recommended only for large data sets and large bird assemblages. 5. The responsible study of wildlife using a drone should only be carried out by persons experienced in the biology and behaviour of the animals concerned.

In 1990, a well-known model to predict pure component properties of triglycerides was presented by Wesdorp in “Liquid-multiple solid phase equilibria in fats: theory and experiments” and has been shown to perform well despite making thermodynamically inconsistent predictions for certain test cases. In this study, the underlying parameter set is improved to deliver more physically consistent predictions, i.e., increasing melting point and enthalpy of fusion with increasing stability of the polymorphs, without deterioration of the primary model quality to describe the available experimental data. Interestingly, when a curated dataset containing only thermodynamically consistent data is compared to a broader dataset, it appears that the model’s efficacy is highly dependent on the quantity of data, specifically the number of unsaturated triglycerides data. Quality and thermodynamic consistency of model predictions and the condition of a reliable description of monoacid triglycerides as a subset is discussed, addressing a potential interdependence.

Glycoside hydrolase family 57 glycogen branching enzymes (GH57GBE) catalyze the formation of an α-1,6 glycosidic bond between α-1,4 linked glucooliogosaccharides. As an atypical family, a limited number of GH57GBEs have been biochemically characterized so far. This study aimed at acquiring a better understanding of the GH57GBE family by a systematic sequence-based bioinformatics analysis of almost 2,500 gene sequences and determining the branching activity of several native and mutant GH57GBEs. A correlation was found between a very low or even no branching activity with the absence of a flexible loop, a tyrosine at the loop tip, and two β-sheets.

Objective: To study complications, within six weeks postpartum, after planned caesarean section (CS) compared with planned vaginal delivery, among women without formal indication for caesarean section. Design: Retrospective cohort study. Setting: Swedish national registries. Population: 714 326 deliveries, 2008-2017. Methods: The risks of complications were compared between planned caesarean section and planned vaginal delivery among women without formal medical indication for planned CS. Adjusted Risk Ratios (ARR) were obtained using modified Poisson-regression models adjusting for; maternal age, parity, body mass index, smoking, country of birth, and county. Main outcome measure: infections, haemorrhage and thromboembolism. Results:. In the planned CS group (n=22 855), 15% had a postpartum infection compared with 10% in the planned vaginal group (n=691 471) (ARR=1.6; 95%CI 1.5-1.6), 8.4% vs 0.6% had haemorrhage >1 litre (ARR=13.4; 95%CI 12.7-14.2), and 0.08% vs 0.05% had a postpartum pulmonary embolism (ARR=1.7; 95%CI 1.0-2.6). The obtained risk estimates correspond to a Number-Needed-to-Harm estimate of 17, 14, and 3448, respectively. When dividing the infections into subgroups, an increased risk of endometritis (ARR 1.2; 95%CI 1.1-1.3), wound infection (ARR 2.7 95%CI 2.4-3.0), urinary tract infections (ARR 1.5 95%CI 1.3-1.7), and mastitis (ARR 2.0; 1.9-2.2) was found after planned CS. Conclusion: The risks of short-term maternal complications were higher in women delivered by planned CS compared with planned vaginal delivery among women without formal medical indication for planned CS. Funding: Gorthon Foundation. Key words: caesarean section, puerperal infection, haemorrhage, thromboembolism.

Summary: This study evaluates through modeling the possible individual and combined effect of three populational parameters of pathogens (reproduction rate; rate of novelty emergence; and propagule size) on the colonization of new host species – putatively the most fundamental process leading to the emergence of new infectious diseases. The results are analyzed under the theoretical framework of the Stockholm Paradigm using IBM simulations to better understand the evolutionary dynamics of the pathogen population and the possible role of Ecological Fitting. The simulations suggest that all three parameters positively influence the success of colonization of new hosts by a novel parasite population but contrary to the prevailing belief, the rate of novelty emergence (e.g. mutations) is the least important factor. Maximization of all parameters result in a synergetic facilitation of the colonization and emulates the expected scenario for pathogenic microorganisms. The simulations also provide theoretical support for the retention of the capacity of fast-evolving lineages to retro-colonize their previous host species/lineage by ecological fitting. Capacity is, thus, much larger than we can anticipate. Hence, the results support the empirical observations that opportunity of encounter (i.e. the breakdown in mechanisms for ecological isolation) is a fundamental determinant to the emergence of new associations – especially Emergent Infectious Diseases - and the dynamics of host exploration, as observed in SARS-CoV-2. Insights on the dynamics of Emergent Infectious Diseases derived from the simulations and from the Stockholm Paradigm are discussed.

Background Timing of aortic valve intervention is dependent on the accuracy and reproducibility of echocardiographic (ECHO) parameters. We aimed to assess haemodynamic subsets of aortic stenosis (AS), their change over time, and variability of ECHO parameters. Method This retrospective, longitudinal study compared sequential ECHO over 15 months to identify concordant or discordant aortic valve area (AVA) and mean pressure gradient (MPG). Results We included 143 patients with a mean age of 76.0 years. The median length of time between studies was 112 days (IQR 38-208). Initially participants were classified as 10 (7.0%) mild, 49 (34.3%) moderate and 84 (58.7%) severe AS. In 80 (55.9%) AVA and MPG were concordant; stroke volume index (SVi) was <35ml/m2 in 53 (74.6%). AS severity was downgraded in 33 (23.1%) patients. MPG was most consistent and AVA was the least consistent between successive investigations (intraclass correlation coefficients R=0.86 and R=0.76, respectively). Even small variations in left ventricular outflow tract (LVOT) measurement of 1 standard deviation reclassified up to 67% of participants from severe to non-severe. Conclusion Almost half of patients with AS have valve area/gradient discordance. Variations in LVOT diameter measurement commensurate with clinical practice reclassified AS severity in up to 2/3 of cases. Change in AS severity should only be accepted following careful scrutiny of all available ECHO data.

Pathogen-mediated selection (PMS) is thought to maintain the high level of allelic diversity observed in the major histocompatibility complex (MHC) class II genes. A comprehensive way to demonstrate contemporary selection is to examine associations between MHC variation and individual fitness. As individual fitness is hard to measure, many studies examine associations between MHC diversity and phenotypic traits which include direct or indirect measures of adaptive immunity thought to contribute to fitness. Here, we tested associations between MHC class II variation and five representative phenotypic traits measured in August: weight, strongyle faecal egg count, and plasma IgA, IgE and IgG immunoglobulin titres against the gastrointestinal nematode parasite Teladorsagia circumcincta in a free-living population of Soay sheep. We found no association between MHC class II variation and August weight or strongyle faecal egg count. We did however find associations between MHC class II variation and immunoglobulin levels which varied with age, isotype and sex. Our results suggest associations between MHC and phenotypic traits are more likely to be found for traits more closely associated with pathogen defence than integrative traits such as body weight and highlight a useful role of MHC-antibody associations in examining selection on MHC genes.
