A Bioinspired Design of Protective Al2O3/Polyurethane Hierarchical Composite Film Through Layer-By-Layer Deposition.

Structural materials such as ceramics, metals, and carbon fiber-reinforced plastics (CFRP) are frequently threatened by large compressive and impact forces. Energy absorption layers, i.e., polyurethane and silicone foams with excellent damping properties, are applied on the surfaces of different substrates to absorb energy. However, the amount of energy dissipation and penetration resistance are limited in commercial polyurethane foams. Herein, a distinctive nacre-like architecture design strategy is proposed by integrating hard porous ceramic frameworks and flexible polyurethane buffers to improve energy absorption and impact resistance. Experimental investigations reveal the bioinspired designs exhibit optimized hardness, strength, and modulus compared to that of polyurethane. Due to the multiscale energy dissipation mechanisms, the resulting normalized absorbed energy (≈8.557 MJ m-3) is ≈20 times higher than polyurethane foams under 50% quasi-static compression. The bioinspired composites provide superior protection for structural materials (CFRP, glass, and steel), surpassing polyurethane films under impact loadings. It is shown CFRP coated with the designed materials can withstand more than ten impact loadings (in energy of 10 J) without obvious damage, which otherwise delaminates after a single impact. This biomimetic design strategy holds the potential to offer valuable insights for the development of lightweight, energy-absorbent, and impact-resistant materials.

Photocatalytic degradation of methylene blue by TiO2/Nd2O3 composite thin films.

To improve the photocatalytic property of TiO2 thin films, the composite thin films of TiO2/Nd2O3 structure were fabricated by electron-beam physical vapor deposition method, and the photocatalytic property of the fabricated films was experimentally studied in the present work. The XRD and Raman analyses show that the TiO2/Nd2O3 films are mainly hexagonal crystalline phase of Nd2O3. The XPS analysis for the chemical state changes of Ti, O and Nd of the basic elements in the films is confirming the electron flow in the internal electric field which generated in the TiO2/Nd2O3 films. The surface morphology shows the lattice distortion which affects the changes in the energy band structure. Moreover, the formation of n-n homojunctions improved the separation efficiency of electrons and holes, and enhanced the catalytic activity. The photocatalytic performance for the methylene blue target dye shows that the sample with TiO2 thickness of 20-25 nm has better performance, high degradation efficiency and high reaction rate.

Overexpressing Bcl-2 enhances murine chimeric antigen receptor T cell therapy against solid tumor.

Chimeric antigen receptor T (CART) cell therapy has demonstrated promising potential in the treatment of hematologic malignancies. However, its application to solid tumors is limited due to the restrictive nature of the tumor microenvironment, resulting in functional failure and poor persistence of CART cells. Overexpression of Bcl-2 in human CART cells (hCART) has been found to significantly enhance their anti-apoptotic effects both in vitro and in vivo. Nevertheless, the evaluation of hCART cells in preclinical studies has predominantly relied on immunodeficient mice xenograft tumor models, making it challenging to assess the impact of hCART cells on normal tissues and the immune system. We established a murine CART (mCART) that overexpresses Bcl-2 and targets the epidermal growth factor receptor variant III (EGFRvIII), named EGFRvIII·mCART-Bcl2. It demonstrated superior proliferation, cytotoxicity, and anti-apoptotic capabilities in vitro. In an immunocompetent mouse model of abdominal metastasis of colorectal cancer, EGFRvIII·mCART-Bcl2 exhibited improved survival of CART in the abdomen, increased tumor clearance, and significantly prolonged overall mouse survival. In summary, our study provides evidence that the introduction of Bcl-2 into mCART cells can enhance their therapeutic efficacy against solid tumors while ensuring safety.

Probabilistic Estimation of Airborne Micro- and Nanoplastic Intake in Humans.

Little research exists on the magnitude, variability, and uncertainty of human exposure to airborne micro- and nanoplastics (AMNPs), despite their critical role in human exposure to MNPs. We probabilistically estimate the global intake of AMNPs through three main pathways: indoor inhalation, outdoor inhalation, and ingestion during indoor meals, for both children and adults. The median inhalation of AMPs is 1,207.7 (90% CI, 42.5-8.48 × 104) and 1,354.7 (90% CI, 47.4-9.55 × 104) N/capita/day for children and adults, respectively. The annual intake of AMPs is 13.18 mg/capita/a for children and 19.10 mg/capita/a for adults, which is approximately one-fifth and one-third of the mass of a standard stamp, assuming a consistent daily intake of medians. The majority of AMP number intake occurs through inhalation, while the ingestion of deposited AMPs during meals contributes the most in terms of mass. Furthermore, the median ANP intake through outdoor inhalation is 9,638.1 N/day (8.23 × 10-6 µg/d) and 5,410.6 N/day (4.62 × 10-6 µg/d) for children and adults, respectively, compared to 5.30 × 105 N/day (5.79 × 10-4 µg/d) and 6.00 × 105 N/day (6.55 × 10-4 µg/d) via indoor inhalation. Considering the increased toxicity of smaller MNPs, the significant number of ANPs inhaled warrants great attention. Collaborative efforts are imperative to further elucidate and combat the current MPN risks.

PTPN7 mediates macrophage-polarization and determines immunotherapy in gliomas: A single-cell sequencing analysis.

BACKGROUND: Protein tyrosine phosphatase non-receptor type 7 (PTPN7) is a signaling molecule that regulates a multitude of cellular processes, spanning cell proliferation, cellular differentiation, the mitotic cycle, and oncogenic metamorphosis. However, the characteristic of PTPN7 in the glioma microenvironment has yet to be elucidated. METHODS: The prognostic value, genomic features, immune characteristics, chemotherapy prediction, and immunotherapy prediction of PTPN7 were systematically explored at the bulk sequencing level. The cell evolution trajectory, cell communication pattern, and cell metabolic activity related to PTPN7 were systematically explored at the single-cell sequencing level. HMC3 and M0 cells were cocultured with U251 and T98G cells, and flow cytometry was carried out to investigate the polarization of HMC3 and M0. Transwell assay and CCK-8 assay were performed to explore the migration and proliferation activity of U251 and T98G. RESULTS: The expression level of PTPN7 is significantly elevated in glioma and indicates malignant features. PTPN7 expression predicts worse prognosis of glioma patients. PTPN7 is associated with genome alteration and immune infiltration. Besides, PTPN7 plays a crucial role in modulating metabolic and immunogenic processes, particularly by influencing the activity of microglia and macrophages through multiple signaling pathways involved in cellular communication. Specifically, PTPN7 actively mediates inflammation-resolving-polarization of macrophages and microglia and protects glioma from immune attack. PTPN7 could also predict the response of immunotherapy. CONCLUSIONS: PTPN7 is critically involved in inflammation-resolving-polarization mediated by macrophage and microglia and promotes the immune escape of glioma cells.

Obese patients with new onset atrial fibrillation/flutter have higher risk of hospitalization, cardioversions, and ablations.

Obesity significantly increases the risk of developing atrial fibrillation (AF) and atrial flutter (AFL) and evidence from randomized trials indicates that weight loss may reduce the burden of AF/AFL in obese patients; however, the relationship between obesity and healthcare resource utilization in AF/AFL patients is lacking. We sought to assess this relationship in patients with newly diagnosed AF/AFL in a nationally representative cohort of the United States by using the MarketScan® claims database. International Classification of Diseases, Tenth Revision [ICD 10] diagnosis codes were used to select individuals with a new diagnosis of AF/AFL in 2017 and 2018, adjudicate baseline variables and to classify them according to obesity status. Patients were followed for two years at which point all data was censored. The primary outcome of the study was hospitalizations due to AF/AFL. Cox proportional hazards regression models were used to assess the adjusted hazard ratio for obese versus non-obese patients. There were 55,271 patients with new onset AF/AFL, which included 43,314 (78.4 %) who were non-obese and 11,957 (21.6 %) who were obese. There were significantly more males than females among non-obese (65.3 % vs. 34.7 %) and obese individuals (62.3 % vs. 37.7 %). The average age (SD) was similar in the non-obese (54.5 (9.7)) and obese cohorts (54.7 (8.4)), respectively. The incidence of Emergency Department visits (4.0 % vs. 6.5 %), hospitalizations (5.5 % vs. 10.7 %), cardioversions (6.6 % vs. 12.7 %), and ablation procedures (5.3 % vs. 8.6 %) were significantly increased among obese patients.

A novel strategy to induce penile erection during penile doppler ultrasound: oral sildenafil administration plus alprostadil injection.

OBJECTIVES: To evaluate the efficacy of a novel approach to achieve the optimal penile erection during the penile doppler ultrasound (PDU) examination, which was oral sildenafil combined alprostadil injection. MATERIALS AND METHODS: A total of 60 ED patients were enrolled in our prospective study, and they were randomly assigned to two group with different PDU order. The approaches assisted the PDU included two models, mode A meaning injection of 15 µg alprostadil and model B meaning oral sildenafil 100 mg plus injection of 15 µg alprostadil. The PDU parameters were measured continuously before induced erection, and 5, 10, 15, 20, 25 min. RESULTS: Each group included 30 ED patients with similar clinical characteristics. After pooling the results together, the PSV, EDV, and RI were all improved significantly, when adding the oral sildenafil administration to assist PDU. Also, the clinical response of oral sildenafil administration plus alprostadil injection was better than that in alprostadil injection alone (p = 0.016). The arterial ED were decreased from 31.67% to 15.00% with the P value 0.031, and the mixed ED was also decreased statistically (23.33% vs 8.33%, p = 0.024). CONCLUSION: Oral sildenafil administration plus alprostadil injection could improve the diagnostic accuracy of PDU.

Progress in Biological Research and Treatment of Pseudomyxoma Peritonei.

Pseudomyxoma peritonei (PMP) is a rare disease characterized by extensive peritoneal implantation and mass secretion of mucus after primary mucinous tumors of the appendix or other organ ruptures. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is currently the preferred treatment, with excellent efficacy and safety, and is associated with breakthrough progress in long-term disease control and prolonged survival. However, the high recurrence rate of PMP is the key challenge in its treatment, which limits the clinical application of multiple rounds of CRS-HIPEC and does not benefit from conventional systemic chemotherapy. Therefore, the development of alternative therapies for patients with refractory or relapsing PMP is critical. The literature related to PMP research progress and treatment was searched in the Web of Science, PubMed, and Google Scholar databases, and a literature review was conducted. The overview of the biological research, treatment status, potential therapeutic strategies, current research limitations, and future directions associated with PMP are presented, focuses on CRS-HIPEC therapy and alternative or combination therapy strategies, and emphasizes the clinical transformation prospects of potential therapeutic strategies such as mucolytic agents and targeted therapy. It provides a theoretical reference for the treatment of PMP and the main directions for future research.

Association between overactive bladder and depression in American adults: A cross-sectional study from NHANES 2005-2018.

BACKGROUND AND AIM: Overactive bladder (OAB) and depression are both common disorders and there is research suggesting an association between the two, but there is a lack of studies with large samples. The aim of this study is to investigate the association between OAB and depressive symptoms. METHODS: We used data from the National Health and Nutrition Examination Survey (NHANES) database for the period 2005 to 2018. OAB was characterized by the Overactive Bladder Symptom Score (OABSS, score > 3) and depression was diagnosed by the Patient Health Questionnaire (PHQ-9, score ≥ 10). There were three models employed in our analysis: (1) Crude model was unadjusted; (2) Model 1 was adjusted for age, sex, race/ethnicity, educational level, and marital status; (3) Model 2 was adjusted for factors in Model 1 plus the remained potential covariates. We used survey-weighted logistic regression models to assess the association between OAB and depression. Subsequently, subgroup analyses and smoothed curve analyses were used to evaluate the reliability of the findings. RESULTS: Finally, a total of 6612 participants were included in our study, consisting of 1005 participants with diagnosis of OAB and 5607 participants without diagnosis of OAB. After adjusting for all covariates, there was a significant positive association between OAB and depression (OR: 2.89, 95 % CI: 1.91, 4.37). The severity of OAB was also positively associated with depression. Compared to participants without OAB, the fully adjusted ORs for depression were 2.76 (95 % CI: 1.64, 4.65) for those with mild OAB, 3.79 (95 % CI: 1.68, 8.55) for those with moderate OAB, and 5.21 (95 % CI: 1.39, 19.53) for those with severe OAB. CONCLUSIONS: This study revealed a strong association between OAB and depression and a progressive increase in the risk of depression as the severity of OAB (mild, moderate, and severe) increased. Therefore, it is important for clinicians to recognize the assessment of OAB symptoms in patients who are at risk for or have developed depressive symptoms, as well as the mental health of patients with OAB.

Association between severe headache or migraine and erectile dysfunction in American adults: a cross-sectional of data study from the NHANES.

Currently, few studies have explored the relationship between severe headache or migraine and erectile dysfunction (ED). The aim of our study was to assess the association between severe headache or migraine and ED in adult men in the US from the National Health and Nutrition Examination Survey (NHANES). We used data from two separate NHANES datasets for the analysis: 2001-2002 and 2003-2004. We used multiple logistic regression, subgroup analysis, and sensitivity analyses to assess the relationship between severe headache or migraine and ED. From 2001 to 2004, 3117 adult male participants (582 ED patients, 2535 non-ED patients) were identified. Categorical and continuous variables are described using counts and frequencies and means and standard errors, respectively. For continuous variables, the two groups were compared using survey-weighted linear regression, while for categorical variables, survey-weighted chi-square tests were performed. Multiple logistic regression analysis showed that in the fully adjusted Model 3, severe headache or migraine was statistically significantly associated with ED (OR 1.51; 95% CI 1.14-1.99; P = 0.0036). In the fully adjusted Model 3, the results of the subgroup analysis showed that an age of 40-60 years (OR = 1.55, 95% CI: 1.05, 2.31, P = 0.029), a body mass index (BMI) < 25 kg/m2 (OR = 1.68, 95% CI: 1.02, 2.75, P = 0.0406) or ≥30 kg/m2 (OR = 1.65, 95% CI: 1.07, 2.54, P = 0.022), hypertension (OR = 1.78, 95% CI: 1.22, 2.60, P = 0.0029), diabetes mellitus (OR = 1.71, 95% CI: 1.26, 2.31, P < 0.001), CVD (OR = 1.54, 95% CI: 1.12, 2.10, P = 0.011) and hyperlipidemia (OR = 1.83, 95% CI: 1.07, 3.13, P = 0.028) were associated with ED with severe headache or migraine. This study demonstrated a statistically significant association between severe headache or migraine and ED among adult men in the US. However, the results of the study should be interpreted with caution due to the failure to assess the effects of depression and anxiety on the outcomes.

A molecular view of single-atom catalysis toward carbon dioxide conversion.

Carbon dioxide (CO2) conversion has attracted much interest recently owing to its importance in both scientific research and practical applications, but still faces a bottleneck in selectivity control and mechanism understanding owing to diversified active sites. Single-atom catalysts (SACs) featuring isolated and well-defined active centers are proved to not only exhibit unparalleled performances in various processes of CO2 conversion but also provide excellent research paradigms by circumventing the heterogeneity of active sites. Herein, we will not only critically review recent progress on the application of SACs in chemical CO2 conversion based on previous comprehension of general thermodynamics and kinetics, but also try to offer a multi-level understanding of SACs from a molecular point of view in terms of the central atom, coordination environment, support effect and synergy with other active centers. Meanwhile, crucial scientific issues of research methods will be also identified and highlighted, followed by a future outlook that is expected to present potential aspects of further developments.

Transcription factors in chimeric antigen receptor T-cell development.

Chimeric antigen receptor (CAR) T-cell therapy is a new and innovative approach to treating cancers that has shown promising results in the treatment of lymphoma. However, it has been found to be less effective in the treatment of solid tumors. To overcome the limitation, researchers have explored the use of combined CAR-T therapy with other complementary regimens that target specific genes or biomarkers, which would enhance the synergistic therapeutic effects. Transcription factors (TFs) have been identified as potential markers that can regulate gene expression in CAR-T cells to enhance their cytotoxicity and safety. TFs are known to bind DNA specifically and recruit cofactor proteins to regulate the expression of target genes. By targeting TFs, it is possible to improve the anti-tumor response of CAR-T cells by altering their phenotype and transcriptional map, thereby increasing their effector function, such as reducing the exhaustion, enhancing the survival, and cytotoxicity of CAR-T cells. This review summarizes the application of transcription factors in CART therapy to enhance the synergistic therapeutic effect of CAR-T cells in the treatment of solid tumors and improve their anti-tumor responses.

Association Between Monocyte-to-High-Density Lipoprotein Ratio and Prediabetes: A Cross-Sectional Study in Chinese Population.

Background: The monocyte-to-high-density lipoprotein cholesterol (MHR) ratio has been linked to metabolic disorders. However, there is limited research on the predisposition to MHR and prediabetes. Hence, we conducted a study to investigate the relationship between MHR and the prevalence of prediabetes. Methods: In total, 85,293 participants were included in our cross-sectional observational study. Multivariable regression analysis, subgroup analyses, and interaction testing were used to determine the relationship between MHR and prediabetes. To explore the non-linear association of MHR with prediabetes risk, generalized additive model (GAM) and smoothing splines were applied. The threshold effect analysis of MHR on the risk of prediabetes was further employed to identify the turning point. Results: After controlling for covariates, the results indicated that a positive correlation persisted between MHR and prediabetes (odds ratio (OR) =1.64, 95% confidence interval (CI), 1.48-1.82), and subgroup analyses found a more robust correlation between MHR and prediabetes in individuals with lower age, SBP, DBP, TG, TC and higher values of BMI and LDL-C than in their counterparts. Additionally, the correlation between MHR and the risk of prediabetes was found to be non-linear, with a turning point of -0.4 (Log-Likelihood Ratio, P< 0.001). The impact of variables on the two sides of the turning point were 1.94 (1.72, 2.19) and 0.88 (0.69, 1.14). Conclusion: The positive correlation between MHR and the risk of prediabetes in Chinese participants was observed to be non-linear, and MHR ≤ -0.4 was strongly positively correlated with prediabetes risk.

Associations between alcohol taxes and varied health outcomes among women of reproductive age and infants.

OBJECTIVE: No studies have examined whether alcohol taxes may be relevant for reducing harms related to pregnant people's drinking. METHOD: We examined how beverage-specific ad valorem, volume-based, and sales taxes are associated with outcomes across three data sets. Drinking outcomes came from women of reproductive age in the 1990-2020 US National Alcohol Surveys (N = 11 659 women $\le$ 44 years); treatment admissions data came from the 1992-2019 Treatment Episode Data Set: Admissions (N = 1331 state-years; 582 436 pregnant women admitted to treatment); and infant and maternal outcomes came from the 2005-19 Merative Marketscan® database (1 432 979 birthing person-infant dyads). Adjusted analyses for all data sets included year fixed effects, state-year unemployment and poverty, and accounted for clustering by state. RESULTS: Models yield no robust significant associations between taxes and drinking. Increased spirits ad valorem taxes were robustly associated with lower rates of treatment admissions [adjusted IRR = 0.95, 95% CI: 0.91, 0.99]. Increased wine and spirits volume-based taxes were both robustly associated with lower odds of infant morbidities [wine aOR = 0.98, 95% CI: 0.96, 0.99; spirits aOR = 0.99, 95% CI: 0.98, 1.00] and lower odds of severe maternal morbidities [wine aOR = 0.91, 95% CI: 0.86, 0.97; spirits aOR = 0.95, 95% CI: 0.92, 0.97]. Having an off-premise spirits sales tax was also robustly related to lower odds of severe maternal morbidities [aOR = 0.78, 95% CI: 0.64, 0.96]. CONCLUSIONS: Results show protective associations between increased wine and spirits volume-based and sales taxes with infant and maternal morbidities. Policies that index tax rates to inflation might yield more public health benefits, including for pregnant people and infants.

The dynamic surface evolution of halide perovskites induced by external energy stimulation.

Tracking the dynamic surface evolution of metal halide perovskite is crucial for understanding the corresponding fundamental principles of photoelectric properties and intrinsic instability. However, due to the volatility elements and soft lattice nature of perovskites, several important dynamic behaviors remain unclear. Here, an ultra-high vacuum (UHV) interconnection system integrated by surface-sensitive probing techniques has been developed to investigate the freshly cleaved surface of CH3NH3PbBr3  in situ under given energy stimulation. On this basis, the detailed three-step chemical decomposition pathway of perovskites has been clarified. Meanwhile, the evolution of crystal structure from cubic phase to tetragonal phase on the perovskite surface has been revealed under energy stimulation. Accompanied by chemical composition and crystal structure evolution, electronic structure changes including energy level position, hole effective mass, and Rashba splitting have also been accurately determined. These findings provide a clear perspective on the physical origin of optoelectronic properties and the decomposition mechanism of perovskites.

Relationships Between Alcohol Policies and Infant Morbidities and Injuries.

INTRODUCTION: Previous research has found that policies specifically focused on pregnant people's alcohol use are largely ineffective. Therefore, the purpose of this study is to analyze the relationships between general population policies regulating alcohol physical availability and outcomes related to pregnant people's alcohol use, specifically infant morbidities and injuries. METHODS: Outcome data were obtained from Merative MarketScan, a longitudinal commercial insurance claims data set. Policy data were obtained from the National Institute on Alcohol Abuse and Alcoholism's Alcohol Policy Information System, the National Alcohol Beverage Control Association, and Liquor Handbooks and merged using policies in effect during the estimated year of conception. Relationships between state-level policies regulating sites, days/hours, and government monopoly of liquor sales and infant morbidities and injuries were examined. Analyses used logistic regression with individual controls, fixed effects for state and year, state-specific time trends, and SEs clustered by state. The study analysis was conducted from 2021 to 2023. RESULTS: The analytic sample included 1,432,979 infant-birthing person pairs, specifically people aged 25-50 years who gave birth to a singleton between 2006 and 2019. A total of 3.1% of infants had a morbidity and 2.1% of infants had an injury. State government monopoly on liquor sales was associated with reduced odds of infant morbidities and injuries, whereas gas station liquor sales were associated with increased odds of infant morbidities and injuries. Allowing liquor sales after 10PM was associated with increased odds for infant injuries. No effect was found for allowing liquor sales in grocery stores or on Sundays. CONCLUSIONS: Findings suggest that limiting alcohol availability for the general population may help reduce adverse infant outcomes related to pregnant people's alcohol use.

On cognitive epidemic models: spatial segregation versus nonpharmaceutical interventions.

Fick's law and the Fokker-Planck law of diffusion are applied to manifest the cognitive dispersal of individuals in two reaction-diffusion SEIR epidemic models, where the disease transmission is illustrated by nonlocal infection mechanisms in heterogeneous environments. Building upon the well-posedness of solutions, threshold dynamics are discussed in terms of the basic reproduction numbers for the two cognitive epidemic models. The numerical investigation reveals that the Fokker-Planck law can better describe the diffusion of individuals by taking different dispersal strategies of exposed individuals in our cognitive epidemic models, and provides some insights on spatial segregation and nonpharmaceutical interventions: (i) spatial segregation occurs in the random diffusion model when the nonlocal infection radius is small, while it appears in the symmetric diffusion model when the radius is large; (ii) nonpharmaceutical interventions on restricting the dispersal of exposed and infected individuals do not contribute to reducing the infection proportion, but rather eliminate the disease in a region, which expands as the nonlocal infection radius increases. We additionally find that the final infection size in the random diffusion model is significantly smaller than that in the symmetric diffusion model and decreases as the nonlocal infection radius increases.

MdSnRK1.1 interacts with MdGLK1 to regulate abscisic acid-mediated chlorophyll accumulation in apple.

Abscisic acid (ABA), as a plant hormone, plays a positive role in leaf chlorosis; however, the underlying molecular mechanism is less known. Our findings provide ABA treatment reduced the chlorophyll accumulation in apple, and Malus × domestica Sucrose Non-fermenting 1-Related Protein Kinase 1.1 (MdSnRK1.1) participates in the process. MdSnRK1.1 interacts with MdGLK1, a GOLDEN2-like transcription factor that orchestrates development of the chloroplast. Furthermore, MdSnRK1.1 affects MdGLK1 protein stability through phosphorylation. We found that Ser468 of MdGLK1 is target site of MdSnRK1.1 phosphorylation. MdSnRK1.1-mediated phosphorylation was critical for MdGLK1 binding to the target gene MdHEMA1 promoters. Collectively, our results demonstrate that ABA activates MdSnRK1.1 to degrade MdGLK1 and inhibit the accumulation of chlorophyll. These findings extend our understanding on how MdSnRK1.1 balances normal growth and hormone response.

Comparative Impact of Asthma Biologics: A Nationwide US Claim-Based Analysis.

BACKGROUND: Biologic modifiers targeting type 2 (T2) airway inflammation are effective in reducing asthma exacerbation. However, real-world and comparative effectiveness studies remain limited. OBJECTIVE: To examine and compare the real-world impact of anti-T2 asthma biologics. METHODS: In this retrospective, new user cohort study, we used the MarketScan, a Commercial Claims and Encounters Database, to identify adult patients with asthma who began to receive an anti-T2 biologic agent (anti-IL-5s, dupilumab, or omalizumab). We examined the influence of the biologic class on asthma exacerbation by comparing the average number of asthma exacerbation 1 year before and after biologic initiation. We conducted multivariable regression analyses to compare the effectiveness of these asthma biologics on reducing the incidence of asthma exacerbations within 18 months of the initial administration of biologics while controlling for demographic variables, comorbidities, and asthma severity. RESULTS: We identified 5,538 asthma patients who were new to taking an anti-T2 biologic [mean age [±SD], 45.6 (12.78) years; 65.8% female). Asthma biologics reduced asthma exacerbation by 11% to 47%, particularly among patients with two or more asthma exacerbations in the year preceding biologic initiation (31% to 65% reduction). Biologics were especially effective in reducing asthma-related hospitalizations (44.6% to 60%). After adjusting for baseline demographics, asthma medication, and comorbidities, dupilumab was associated with a lower estimated mean number of asthma exacerbation per year and lower adjusted odds ratio for developing an asthma exacerbation relative to other biologics (50% to 80% less likely). CONCLUSIONS: Anti-T2 asthma biologics reduced asthma exacerbation in real-word settings. Evidence supports growing literature reporting that dupilumab might have a more favorable impact on asthma exacerbation relative to other asthma biologics.

Effect of starch and protein on eating quality of japonica rice in Yangtze River Delta.

This study examined four types of japonica rice from Yangtze River Delta, categorized based on amylose content (AC) and protein content (PC): high AC with high PC, high AC with low PC, low AC with high PC, and low AC with low PC. It systematically explored the effect of starch, protein and their interactions on eating quality of japonica rice. Rheological analysis revealed that increased amylose, long chains amylopectin or protein levels during cooking strengthen starch-protein interactions (hydrogen bonding), forming a firm gel network. Scanning electron microscopy showed that increased amylose, long chains amylopectin or protein levels made protein and starch more stable in combination during cooking, limiting starch structure cleavage. Therefore, the eating quality of high AC in similar PC japonica rice and high PC in similar AC japonica rice were poor. Further, correlation and random-forest analysis (RFA) identified amylose as the most influential factor in starch-protein interactions affecting rice eating quality, followed by amylopectin and protein. RFA also revealed that in high AC japonica rice, the interactions of Fb3 and albumin with amylose were more conducive to forming good eating quality. In low AC japonica rice, the interactions of Fb2 and prolamin with amylose were more beneficial.
