Wnt-5a-Receptor Tyrosine Kinase-Like Orphan Receptor 2 Signaling Provokes Metastatic Colonization and Angiogenesis in Renal Cell Carcinoma, and the Axis Activation Is Suppressed by Prunetin.

Wnt-5a is a protein that is encoded by the WNT5A gene and is a ligand for the receptor tyrosine kinase-like orphan receptor 2 (ROR2). However, its biological impact on clear cell renal cell carcinoma (ccRCC) remains unclear. In this study, the prognostic significance of concurrent WNT5A and ROR2 expression levels was observed to predict unfavorable overall survival and disease-specific survival. High Wnt-5a expression was detected in a ccRCC cell line panel but not in HK-2 cells, a normal proximal tubular cell line. Inhibition of DNA methyltransferase by 5-azacytidine in 786-O and Caki-2 cells resulted in Wnt-5a up-regulation, indicating potential epigenetic modification. Furthermore, the results revealed the repression of cell movement in vitro and metastatic colonization in vivo on WNT5A and ROR2 knockdown. The suppressions of angiogenesis in vivo and tubular-like structure formation in endothelial cells in vitro were also observed after silencing WNT5A and ROR2 expression. In addition, alteration in the downstream gene signature of the Wnt-5a-ROR2 signaling was discovered to be similar to that in metastasis-associated gene 1-ß-catenin axis. Moreover, prunetin treatment was found to reverse the gene signature derived from Wnt-5a-ROR2 signaling activation and to abolish ccRCC cell migration and proliferation. Overall, this study demonstrates the clinical and functional significance of the Wnt-5a-ROR2 axis and identifies prunetin as a potential precision medicine for patients with ccRCC harboring aberrant Wnt-5a-ROR2 signaling pathways.

Liquid-Liquid Phase Separation Mediated Formation of Chiral 2D Crystalline Nanosheets of a Co-Assembled System.

The role of macromolecule-macromolecule and macromolecule-H2O interactions and the resulting perturbation of the H-bonded network of H2O in the liquid-liquid phase separation (LLPS) process of biopolymers are well-known. However, the potential of the hydrated state of supramolecular structures (non-covalent analogs of macromolecules) of synthetic molecules is not widely recognized for playing a similar role in the LLPS process. Herein, LLPS occurred during the co-assembly of hydrated supramolecular vesicles (bolaamphiphile, BA1) with a net positive charge (zeta potential, ζ = +60 ± 2 mV) and a dianionic chiral molecule (disodium l-[+]-tartrate) is reported. As inferred from cryo-transmission electron microscopy (TEM), the LLPS-formed droplets serve as the nucleation precursors, dictating the structure and properties of the co-assembly. The co-assembled structure formed by LLPS effectively integrates the counter anion's asymmetry, resulting in the formation of ultrathin free-standing, chiral 2D crystalline sheets. The significance of the hydrated state of supramolecular structures in influencing LLPS is unraveled through studies extended to a less hydrated supramolecular structure of a comparable system (BA2). The role of LLPS in modulating the hydrophobic interaction in water paves the way for the creation of advanced functional materials in an aqueous environment.

Recent advances in LC-MS-based metabolomics for clinical biomarker discovery.

The employment of liquid chromatography-mass spectrometry (LC-MS) untargeted and targeted metabolomics has led to the discovery of novel biomarkers and improved the understanding of various disease mechanisms. Numerous strategies have been reported to expand the metabolite coverage in LC-MS-untargeted and targeted metabolomics. To improve the sensitivity of low-abundance or poor-ionized metabolites for reducing the amount of clinical sample, chemical derivatization methods are used to target different functional groups. Proper sample preparation is beneficial for reducing the matrix effect, maintaining the stability of the LC-MS system, and increasing the metabolite coverage. Machine learning has recently been integrated into the workflow of LC-MS metabolomics to accelerate metabolite identification and data-processing automation, and increase the accuracy of disease classification and clinical outcome prediction. Due to the rapidly growing utility of LC-MS metabolomics in discovering disease markers, this review will address the recent advances in the field and offer perspectives on various strategies for expanding metabolite coverage, chemical derivatization, sample preparation, clinical disease markers, and machining learning for disease modeling.

Association between chronic prostatitis and the subsequent benign prostatic hyperplasia: a population-based national cohort study.

PURPOSE: To explore the association between chronic prostatitis (CP) and the subsequent development of benign prostatic hyperplasia (BPH). METHODS: Data analyzed were medical claims of Taiwan's National Health Insurance program. From 2010 to 2017, 3571 patients ≧20 years with CP diagnosed by certified urologists were enrolled. Patients with past BPH diagnosis and diagnosis of prostate cancer, inguinal hernia, interstitial cystitis, and urethritis in the past and within one year after the first CP diagnosis were excluded. Age-matched controls were randomly selected from all non-CP individuals of the same exclusion criteria in the study period with a CP/non-CP ratio of 1:4. The follow-up was made from the first CP diagnosis to death or the end of 2018. The endpoint was the newly diagnosed BPH. Cox proportional hazard regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of BPH in association with CP. RESULTS: Over a maximum of 8 years of follow-up, 287 (8.03%) and 258 (0.43%) BPH events were noted for the CP and non-CP group, respectively, representing a covariate adjusted HR (aHR) of 4.30 (95% CI, 3.61-5.13). Younger patients tended to suffer from higher aHRs, especially those aged 20-39 years (aHR: 11.45, 95% CI, 5.12-25.64). CONCLUSION: The Taiwan national health database indicated that CP patients had a significantly higher risk of developing BPH later than non-CP patients. Interestingly, the younger the CP is diagnosed (under 40), the greater the risk.

Effectiveness of abdominal sandbag training in enhancing diaphragm muscle function and exercise tolerance in patients with chronic respiratory failure.

BACKGROUND: Chronic respiratory failure is a common cause of ventilator dependence in the intensive care unit (ICU). The causes of chronic respiratory failure include primary disease or complications, such as ICU-acquired weakness. Traditional practice requires patients to remain immobile and bedridden; however, recent evidence suggests that early adequate exercise promotes recovery without increasing risks. In this study, we explored the efficacy of planned progressive abdominal sandbag training in promoting the successful withdrawal of patients with chronic respiratory failure from mechanical ventilation. METHODS: This study was conducted between April 2019 and November 2020. Patients were recruited and divided into two groups: abdominal sandbag training group and control group (no training). The training group participated in a 3-month daily pulmonary rehabilitation program, which involved a 30-min session of progressive sandbag loading on the upper abdomen as a form of diaphragmatic resistant exercise. The pressure support level of the ventilator was adjusted to maintain a tidal volume of 8 mL/kg. To investigate the effect of abdominal sandbag training on patients with chronic respiratory failure, we compared tidal volume, shallow breathing index, maximum respiratory pressure, and diaphragm characteristics between the training and control groups. RESULTS: This study included 31 patients; of them, 17 (54.8 %) received abdominal sandbag training and 14 (45.2 %) did not. No significant between-group difference was found in baseline characteristics. Compared with the control group, the training group exhibited considerable improvements in ventilation-related parameters (p < 0.001): the tidal volume markedly increased (p = 0.012), rapid shallow breathing index declined (p = 0.016), and maximum respiratory pressure increased (p < 0.001) in the training group. The diaphragm motion value (p = 0.048) and diaphragm thickness (p = 0.041) were greater in the training group than in the control group. Nine patients (52.9 %) in the training group were removed from the ventilator compared with 1 (7.1 %) in the control group (p = 0.008). CONCLUSIONS: Abdominal sandbag training may be beneficial for patients dependent on a ventilator. The training improves the function of the diaphragm muscle, thereby increasing tidal volume and reducing the respiratory rate and rapid shallow breathing index, thus facilitating withdrawal from ventilation. This training approach may also improve the thickness and motion of the diaphragm and the rate of ventilator detachment.

The Beneficial Effect of the SGLT2 Inhibitor Dapagliflozin in Alleviating Acute Myocardial Infarction-Induced Cardiomyocyte Injury by Increasing the Sirtuin Family SIRT1/SIRT3 and Cascade Signaling.

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have a variety of cardiovascular and renoprotective effects and have been developed as novel agents for the treatment of heart failure. However, the beneficial mechanisms of SGLT2i on cardiac tissue need to be investigated further. In this study, we established a mouse model of acute myocardial infarction (AMI) using coronary artery constriction surgery and investigated the role of dapagliflozin (DAPA) in protecting cardiomyocytes from hypoxic injury induced by AMI. In vitro experiments were done using hypoxic cultured H9c2 ventricular cells to verify this potential mechanism. Expression of the SIRT family and related genes and proteins was verified by qPCR, Western blotting and immunofluorescence staining, and the intrinsic potential mechanism of cardiomyocyte death due to AMI and hypoxia was comprehensively investigated by RNA sequencing. The RNA sequencing results of cardiomyocytes from AMI mice showed that the SIRT family may be mainly involved in the mechanisms of hypoxia-induced cardiomyocyte death. In vitro hypoxia-induced ventricular cells showed the role of dapagliflozin in conferring resistance to hypoxic injury in cardiomyocytes. It showed that SIRT1/3/6 were downregulated in H9c2 cells in a hypoxic environment, and the addition of dapagliflozin significantly increased the gene and protein expression of SIRT1, 3 and 6. We then verified the underlying mechanisms induced by dapagliflozin in hypoxic cardiomyocytes using RNA-seq, and found that dapagliflozin upregulated the hypoxia-induced gene downregulation, which includes ESRRA, EPAS1, AGTRAP, etc., that associated with SIRTs-related and apoptosis-related signaling to prevent H9c2 cell death. This study provides laboratory data for SGLT2i dapagliflozin treatment of AMI and confirms that dapagliflozin can be used to treat hypoxia-induced cellular necrosis in cardiomyocytes, in which SIRT1 and SIRT3 may play an important role. This opens up further opportunities for SGLT2i in the treatment of heart disease.

Left Atrial Strain Predicts Cardiovascular and All-Cause Mortality.

Background: Left atrial strain can usefully reflect left atrial function. The follow-up periods in previous studies assessing left atrial strain as a survival predictor have been relatively short, and few studies have examined the ability of left atrial strain to predict mortality in patients with borderline diastolic function. This study sought to investigate the survival predictive value of left atrial strain with a longer follow-up duration. In addition, we also evaluated the survival predictive value of left atrial strain in patients with borderline diastolic function. Methods: In total, 652 participants who received routine echocardiography underwent 2-D speckle tracking echocardiography to evaluate left atrial reservoir function by peak atrial longitudinal strain. The study endpoints were all-cause and cardiovascular mortality. Results: The mean left atrial strain was 27.6%, and the median follow-up duration was 92 months. During follow-up, 72 patients died of cardiovascular causes and 181 died of all causes. Univariable Cox regression analysis revealed that lower left atrial strain significantly predicted an increase in all-cause and cardiovascular mortality. After adjusting for common clinical and echocardiographic parameters, lower left atrial strain was still associated with a higher risk of all-cause mortality [hazard ratio (HR) = 0.942, p = 0.011] and cardiovascular mortality (HR = 0.915, p = 0.018) in multivariable Cox-regression analysis. In addition, 293 patients had borderline left ventricular diastolic function. Multivariable analysis still revealed that left atrial strain could predict cardiovascular mortality in this population. Conclusions: Our data showed that left atrial strain could predict all-cause and cardiovascular mortality, even after adjusting for general clinical and echocardiographic parameters.

Taiwan Society of Cardiology Heart Failure Registry 2020: Rationale and Design.

Background: Heart failure (HF) is a significant public health problem worldwide. Death and rehospitalization rates are similar across different HF phenotypes. However, the existing Taiwanese HF registries mainly enrolled inpatients with HF and reduced ejection fraction (HFrEF) before 2019, so their results may not apply to outpatients or patients with HF with mildly reduced ejection fraction (HFmrEF) and HF with preserved ejection fraction (HFpEF) phenotypes. Methods: The Taiwan Society of Cardiology Heart Failure Registry 2020 is a prospective, multicenter, observational registry that will enroll patients with HF from 27 hospitals in Taiwan between 2020 and 2022 and will be followed for two years. Patients eligible for enrollment include those admitted due to acute decompensated heart failure or outpatients with a history of hospitalization for heart failure within the past six months. The registry will collect patient demographics, medical history, HF diagnosis, medication use, examination results, and comorbidities. The registry plans to enroll 3,370 patients, with the distribution of HFrEF/HFmrEF/HFpEF as 59%/13%/28%. Follow-up intervals will occur every six months for up to two years to monitor clinical outcomes and major cardiac interventions. The registry will conclude in December 2024. Conclusions: The Taiwan Society of Cardiology Heart Failure Registry 2020 is a comprehensive and meticulous effort to demonstrate the epidemiology, adherence to guidelines, clinical outcomes, and disease progression of Taiwanese patients with HF in contemporary clinical practice.

Spontaneous Curvature Induction in an Artificial Bilayer Membrane.

Maintaining lipid asymmetry across membrane leaflets is critical for functions like vesicular traffic and organelle homeostasis. However, a lack of molecular-level understanding of the mechanisms underlying membrane fission and fusion processes in synthetic systems precludes their development as artificial analogs. Here, we report asymmetry induction of a bilayer membrane formed by an extended π-conjugated molecule with oxyalkylene side chains bearing terminal tertiary amine moieties (BA1) in water. Autogenous protonation of the tertiary amines in the periphery of the bilayer by water induces anisotropic curvature, resulting in membrane fission to form vesicles and can be monitored using time-dependent spectroscopy and microscopy. Interestingly, upon loss of the induced asymmetry by extensive protonation using an organic acid restored bilayer membrane. The mechanism leading to the compositional asymmetry in the leaflet and curvature induction in the membrane is validated by density functional theory (DFT) calculations. Studies extended to control molecules having changes in hydrophilic (BA2) and hydrophobic (BA3) segments provide insight into the delicate nature of molecular scale interactions in the dynamic transformation of supramolecular structures. The synergic effect of hydrophobic interaction and the hydrated state of BA1 aggregates provide dynamicity and unusual stability. Our study unveils mechanistic insight into the dynamic transformation of bilayer membranes into vesicles.

Total Synthesis of Campylobacter jejuni NCTC11168 Capsular Polysaccharide via the Intramolecular Anomeric Protection Strategy.

The infection of Campylobacter jejuni results in a significant diarrhea disease, which is highly fatal to young children in unindustrialized countries. Developing a new therapy is required due to increasing antibiotic resistance. Herein, we described a total synthesis of a C. jejuni NCTC11168 capsular polysaccharide repeating unit containing a linker moiety via an intramolecular anomeric protection (iMAP) strategy. This one-step 1,6-protecting method structured the challenging furanosyl galactosamine configuration, facilitated further concise regioselective protection, and smoothed the heptose synthesis. The tetrasaccharide was constructed in a [2 + 1 + 1] manner. The synthesis of this complicated CPS tetrasaccharide was completed in merely 28 steps, including the preparation of all the building blocks, construction of the tetrasaccharide skeleton, and functional group transformations.

Association between immune checkpoint inhibitor-induced myocarditis and concomitant use of thiazide diuretics.

Although an association has been reported between diuretics and myocarditis, it is unclear whether the risk of immune checkpoint inhibitor (ICI)-induced myocarditis is affected by concomitant diuretics. Thus, the aim of this work was to evaluate the impact of concomitant diuretics on ICI-induced myocarditis. This cross-sectional study used disproportionality analysis and a pharmacovigilance database to assess the risk of myocarditis with various diuretics in patients receiving ICIs via the analysis of data entered into the VigiBase database through December 2022. Multiple logistic regression analysis was performed to identify risk factors for myocarditis in patients who received ICIs. A total of 90 611 patients who received ICIs, including 975 cases of myocarditis, were included as the eligible dataset. A disproportionality in myocarditis was observed for loop diuretic use (reporting odds ratio 1.47, 95% confidence interval [CI] 1.02-2.04, P = .03) and thiazide use (reporting odds ratio 1.76, 95% CI 1.20-2.50, P < .01) in patients who received ICIs. The results of the multiple logistic regression analysis showed that the use of thiazides (odds ratio 1.67, 95% CI 1.15-2.34, P < .01) was associated with an increased risk of myocarditis in patients who received ICIs. Our findings may help to predict the risk of myocarditis in patients receiving ICIs.

Association between clinical use of nifedipine and the risk of osteoporosis: a nationwide retrospective cohort study.

Nifedipine is one of the common calcium channel blockers (CCBs) for hypertension that induce peroxisome-proliferator-activated receptor γ coactivator 1-α, which is envisioned as a potential therapeutic target in bone disease. The findings of this retrospective cohort study suggest that patients who receive nifedipine may have a potential protective effect on osteoporosis in comparison to other CCBs. INTRODUCTION: Nifedipine was one L-type dihydropyridine calcium channel blocker (CCB) that can improve bone loss. However, epidemiological studies on the association between the use of nifedipine and osteoporosis risk are limited. Thus, this study aimed to evaluate the association between the clinical use of nifedipine and the risk of osteoporosis. METHODS: This retrospective cohort was conducted using the National Health Insurance Research Database of Taiwan from 2000 to 2013. The study includes 1225 patients receiving nifedipine (the exposed cohort) and 4900 patients receiving other CCBs (the comparison cohort). The primary outcome was the diagnosis of osteoporosis. The hazard ratios (HRs) and 95% confidence intervals (CIs) were used to assess the association between the use of nifedipine and the risk of osteoporosis. RESULTS: Patients receiving nifedipine treatment had a reduced risk of osteoporosis as compared with those undergoing other CCB treatments (adjusted HR, 0.44; 95% CI, 0.37-0.53). Moreover, this inverse association is evident in both sexes and various age groups. CONCLUSIONS: This population-based cohort study demonstrated that nifedipine may have potential protective effect on osteoporosis compared with other CCBs. The clinical implications of the present study need further investigation.

Structural characterization of the optical isomers esomeprazole and omeprazole using the JADER and FAERS databases.

BACKGROUND: It is unclear whether the s (-) form of esomeprazole (EPZ) has an improved safety profile when compared with its racemic form omeprazole (OPZ). We assessed the potential complications of these optical isomers when combined with cilostazol, clopidogrel, and prasugrel, which are frequently used concomitant medications. METHODS: Using two adverse event spontaneous reporting databases, Japanese Adverse Drug Event Report (JADER) and FDA Adverse Event Reporting System (FAERS), adverse event names for hemorrhage, venous/arterial embolization, and thrombus were obtained from the Medical Dictionary for Regulatory Activities. Reported odds ratios were calculated using a 2 × 2 contingency table, and a signal was considered present if the lower limit of the 95% confidence interval was >1. RESULTS: In combination with cilostazol, a hemorrhagic signal for OPZ in JADER and arterial emboli and thrombus signals for EPZ were detected in both databases. In combination with clopidogrel, OPZ showed arterial emboli and thrombus signals in JADER and venous/arterial emboli and thrombus signals in FAERS, while EPZ displayed arterial emboli and thrombus signals in FAERS. In contrast, when in combination with prasugrel, there were no adverse event signals in either database. CONCLUSION: This study has confirmed using big data, that EPZ, the optical isomer and racemic form of omeprazole, has the beneficial characteristics of being less sensitive to CYP, as was intended by its design.

Up-regulated small-conductance calcium-activated potassium currents contribute to atrial arrhythmogenesis in high-fat feeding mice.

AIMS: Metabolic syndrome (MetS) is associated with arrhythmias and cardiovascular mortality. Arrhythmogenesis in MetS results from atrial structural and electrical remodelling. The small-conductance Ca2+-activated K+ (SK) currents modulate atrial repolarization and may influence atrial arrhythmogenicity. This study investigated the regulation of SK current perturbed by a high-fat diet (HFD) to mimic MetS. METHODS AND RESULTS: Thirty mice were divided into two groups that were fed with normal chow (CTL) and HFD for 4 months. Electrocardiography and echocardiography were used to detect cardiac electrical and structure remodelling. Atrial action potential duration (APD) and calcium transient duration (CaTD) were measured by optical mapping of Langendorff-perfused mice hearts. Atrial fibrillation (AF) inducibility and duration were assessed by burst pacing. Whole-cell patch clamp was performed in primarily isolated atrial myocytes for SK current density. The SK current density is higher in atrial myocytes from HFD than in CTL mice (P ≤ 0.037). The RNA and protein expression of SK channels are increased in HFD mice (P ≤ 0.041 and P ≤ 0.011, respectively). Action potential duration is shortened in HFD compared with CTL (P ≤ 0.015). The shortening of the atrial APD in HFD is reversed by the application of 100 nM apamin (P ≤ 0.043). Compared with CTL, CaTD is greater in HFD atria (P ≤ 0.029). Calcium transient decay (Tau) is significantly higher in HFD than in CTL (P = 0.001). Both APD and CaTD alternans thresholds were higher in HFD (P ≤ 0.043), along with higher inducibility and longer duration of AF in HFD (P ≤ 0.023). CONCLUSION: Up-regulation of apamin-sensitive SK currents plays a partial role in the atrial arrhythmogenicity of HFD mice.

Proton Pump Inhibitors and Rhabdomyolysis: Analysis of Two Different Cross-Sectional Databases.

BACKGROUND: It is unclear whether use of a proton pump inhibitors (PPIs) increases the risk of rhabdomyolysis. OBJECTIVE: To clarify whether use of PPIs increases the risk of rhabdomyolysis. METHODS: This cross-sectional study analyzed data entered into the Medical Data Vision (MDV) database in Japan and into the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). The MDV data were analyzed to evaluate the association between use of PPIs and rhabdomyolysis. Then, the FAERS data were analyzed to evaluate whether the risk of rhabdomyolysis was increased further when a statin or fibrate was used concomitantly with a PPI. In both analyses, histamine-2 receptor antagonist was set as a comparator because it is used to treat gastric disease. In the MDV analysis, Fisher's exact test and multiple logistic regression analysis were performed. In the FAERS analysis, a disproportionality analysis using Fisher's exact test and multiple logistic regression analysis were performed. RESULTS: Multiple logistic regression analysis of both databases showed a significant association between use of PPIs and an increased risk of rhabdomyolysis (odds ratio [OR] = 1.74-1.95, P ≤ 0.01). However, use of a histamine-2 receptor antagonist was not significantly associated with increased risk of rhabdomyolysis. In the sub-analysis of the FAERS data, use of a PPI did not increase the risk of rhabdomyolysis in patients receiving a statin. CONCLUSION AND RELEVANCE: The data in 2 separate databases consistently suggest that PPIs may increase the risk of rhabdomyolysis. The evidence for this association should be assessed in further drug safety studies.

Inflammation and renal function decline in chronic coronary syndrome: a prospective multicenter cohort study.

BACKGROUND: Renal function decline is a frequently encountered complication in patients with chronic coronary syndrome. Aside from traditional cardiovascular risk factors, the inflammatory burden emerged as the novel phenotype that compromised renal prognosis in such population. METHODS: A cohort with chronic coronary syndrome was enrolled to investigate the association between inflammatory status and renal dysfunction. Levels of inflammatory markers, including high-sensitivity C-reactive protein (hs-CRP), tumour necrosis factor-α (TNF-α), adiponectin, matrix metalloproteinase-9, interleukin-6, lipoprotein-associated phospholipase A2, were assessed. Renal event was defined as > 25% decline in estimated glomerular filtration rate (eGFR). Inflammatory scores were calculated based on the aggregate of hs-CRP, TNF-α, and adiponectin levels. RESULTS: Among the 850 enrolled subjects, 145 patients sustained a renal event during an averaged 3.5 years follow-up. Multivariate analysis with Cox regression suggested elevations in hs-CRP, TNF-α, and adiponectin levels were independent risk factors for the occurrence of a renal event. Whereas, Kaplan-Meier curve illustrated significant correlation between high TNF-α (P = 0.005), adiponectin (P < 0.001), but not hs-CRP (P = 0.092), and eGFR decline. The aggregative effect of these biomarkers was also distinctly correlated with renal events (score 2: P = 0.042; score 3: P < 0.001). CONCLUSIONS: Inflammatory burden was associated with eGFR decline in patients with chronic coronary syndrome.

Rating System for Phytophthora Root Rot Influences Quantitative Trait Locus Detection and Reveals Incomplete Dominance and Duplicative Recessive Epistatic Gene Action in Capsicum annuum.

Phytophthora capsici is one of the most devastating pathogens facing pepper (Capsicum annuum) producers worldwide. Numerous factors, such as the race of the pathogen, the growing environment, and the source of resistance, have resulted in an overall lack of widely applicable molecular markers associated with resistance. Our objective was to determine the effect of the rating system on quantitative trait locus (QTL) detection and understand inheritance patterns of host resistance that can influence selection and molecular marker accuracy. We evaluated an F2:11 recombinant inbred line population screened against the highly virulent strain (Pc134) and scored using two widely used methods, developed by Bosland and Lindsey and by Black. The rating system developed by Bosland and Lindsey resulted in slightly higher logarithm of odds for the QTL on chromosome 5, and we detected a QTL on chromosome 12 uniquely using this rating system. A QTL on chromosome 10 was detected using both rating systems, but Black resulted in considerably higher logarithm of odds for this QTL compared with the Bosland and Lindsey system. Molecular markers developed were nominally better at accurately predicting the phenotype than previously published molecular markers but did not completely explain resistance in our validation populations. The inheritance pattern of resistance in one of our F2 populations did not significantly deviate from a 7:9 segregation ratio, indicating duplicative recessive epistasis. However, these results could be confounded by the presence of incomplete gene action, which was found through the improved selection accuracy when the phenotypes of heterozygous individuals were grouped with those with susceptible alleles.

Revealing the energy paradox: Assessing the asymmetric impact of pandemic uncertainty on consumption of renewable and nonrenewable energy.

Uncertainties have grown around the world during the last few decades. Pandemic uncertainty has a substantial impact on economic activities, which may have a big influence on energy consumption. The goal of this investigation is to appraise the asymmetric influence of pandemic uncertainty on nonrenewable and renewable energy consumption in the top 10 energy consumer economies of the European Union (Germany, Poland, Spain, Netherlands, France, Italy, Belgium, Sweden, Czech Republic, and Finland). Previously, panel data approaches were utilized to obtain reliable outcomes on the pandemic-energy consumption nexus, regardless of the fact that various nations did not autonomously exhibit similar relationship. This investigation, on the other hand, implements a special technique "Quantile-on-Quantile" that supports us to appraise time-series interdependence in each economy by providing international yet nation-specific perceptions of the connection among the variables. Estimates show that pandemic uncertainty reduces both nonrenewable and renewable energy consumption in most selected nations at stated quantiles of the data distribution. Nonrenewable energy consumption is much more influenced by pandemic uncertainty than renewable energy consumption. Furthermore, the rank of asymmetries across our variables differentiates by the economy, emphasizing the need for decisionmakers to pay much attention to pandemics-related uncertainty and the energy sector.

The sufficient multidisciplinary specialists under a government-led health care system associated with the downward mortality trend of Fournier's gangrene in Taiwan.

OBJECTIVES: To explore the trends in Fournier's gangrene (FG) incidence and mortality rate in Taiwan and to investigate the contributing factors to such changes. METHODS: Between 2002 and 2016, hospitalized FG patients who underwent subsequent surgical intervention were included in this retrospective study. Incidence, outcomes, age-adjusted Charlson Comorbidity Index (ACCI), hospitalization cost, surgical timing, and the number of multidisciplinary specialists involved in the first-line management of FG in each year were collected. Simple linear regression and Pearson correlation coefficient (r) were used for the subsequent analysis. RESULTS: The national cohort enrolled 2183 FG patients from 2002 to 2016 in Taiwan. The age-standardized incidence rate of FG was between 0.4 and 0.8 per 100 000 population, and overall mortality was 7.8% in these 15 years. We illustrated the downward trendline of FG mortality with a 0.62 coefficient of determination. The mortality of FG patients who underwent surgery within 24 h and after 24 h were found to be 8.3 ± 3.9% and 14.6 ± 25.2%, respectively (p = 0.02). The numbers of urologists, anesthesiologists, emergency doctors, and physicians per 100 000 population had a strong negative linear correlation with FG mortality (r = 0.8, p < 0.001). ACCI score had a moderate linear relationship with FG mortality (r = 0.57, p = 0.027). The hospitalization cost showed a weak linear correlation with FG mortality (r = -0.03, p = 0.92). CONCLUSIONS: We demonstrated the downward trend of the FG mortality rate in Taiwan from 2002 to 2016. Besides underlying comorbidities and surgical timing, sufficient multidisciplinary specialists are essential for the survival benefit of FG patients in Taiwan experience.
