RESUMEN
BACKGROUND: Adherence to antiparkinsonian drugs (APDs) is critical for patients with Parkinson's disease (PD), for which medication is the main therapeutic strategy. Previous studies have focused on specific disorders in a single system when assessing clinical factors affecting adherence to PD treatment, and no international comparative data are available on the medical costs for Chinese patients with PD. The present study aimed to evaluate medication adherence and its associated factors among Chinese patients with PD using a systematic approach and to explore the impact of adequate medication adherence on direct medical costs. METHODS: A retrospective analysis was conducted using the electronic medical records of patients with PD from a medical center in China. Patients with a minimum of two APD prescriptions from January 1, 2016 to August 15, 2018 were included. Medication possession ratio (MPR) and proportion of days covered were used to measure APD adherence. Multiple linear regression analysis was used to identify factors affecting APD adherence. Gamma regression analysis was used to explore the impact of APD adherence on direct medical costs. RESULTS: In total, 1,712 patients were included in the study, and the mean MPR was 0.68 (± 0.25). Increased number of APDs and all medications, and higher daily levodopa-equivalent doses resulted in higher MPR (mean difference [MD] = 0.04 [0.03-0.05]; MD = 0.02 [0.01-0.03]; MD = 0.03 [0.01-0.04], respectively); combined digestive system diseases, epilepsy, or older age resulted in lower MPR (MD = -0.06 [-0.09 to -0.03]; MD = -0.07 [-0.14 to -0.01]; MD = -0.02 [-0.03 to -0.01], respectively). Higher APD adherence resulted in higher direct medical costs, including APD and other outpatient costs. For a 0.3 increase in MPR, the two costs increased by $34.42 ($25.43-$43.41) and $14.63 ($4.86-$24.39) per year, respectively. CONCLUSIONS: APD adherence rate among Chinese patients with PD was moderate and related primarily to age, comorbidities, and healthcare costs. The factors should be considered when prescribing APDs.

BACKGROUND: Cough variant asthma (CVA) is one of the most common causes of chronic cough in children worldwide. The diagnosis of CVA in children remains challenging. This study aimed to assess the diagnostic utility of impulse oscillometry (IOS) pulmonary function in children with CVA. METHODS: This study included children aged 4 to 12 years diagnosed with CVA who underwent IOS pulmonary function and bronchodilation (BD) tests. A control group of healthy children was matched. Pre- and post-BD IOS parameters were recorded and presented as mean ± standard deviation or median. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC) was calculated to evaluate the discriminatory potential of the IOS parameters for diagnosing CVA. RESULTS: A total of 180 patients with CVA and 65 control subjects were included. The baseline IOS parameters in the CVA group, except X5%pred, were significantly greater compared to the control group. After inhalation of salbutamol sulfate, all IOS parameters improved significantly in the CVA group. However, Z5%pred, R5%pred, and R20%pred remained greater in the CVA group compared to the control group. The improvement rates of IOS parameters in the CVA group significantly surpassed those in the control group. The ROC curve results for pre-BD IOS parameters and the improvement rate during the BD test showed that the combinations of pre-Z5%pred+â³Z5% and pre-R5%pred+â³R5% achieved the highest AUC value of 0.920 and 0.898, respectively. The AUC values of these combined parameters surpassed those of individual ones. CONCLUSIONS: This study highlights that children with CVA exhibit greater IOS parameters compared to healthy children. The changes in IOS parameters during the BD test provided valuable diagnostic information for CVA, and the combination of various parameters can help pediatricians accurately identify CVA in children.

Objective: The study aims to assess and compare the outcomes of modified radical surgery, preserving the nipple-areola complex, against radical mastectomy in patients with triple-negative breast cancer. Emphasis is placed on the clinical significance of this comparison, including its potential impact on patient outcomes, quality of life, and healthcare resources. Methods: Relevant literature from January 2017 to January 2022 was searched in the following databases: PubMed, Embase, MEDLINE, Science Citation Index, Web of Science, China National Knowledge Internet, CCD, and CSPD with keywords. The electric search yielded 613 relevant articles, including 351 from Pubmed, 187 from Embase, 5 from MEDLINE, 21 from CNKI, 4 from CCD, and 45 from CSPD. After duplicate screening, 185 items were eliminated, leaving 428 articles. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated with RevMan 5.3, and sensitivity analysis, cumulative meta-analysis, and publication bias analysis were also performed. A total of 613 relevant articles were collected from the above databases, among which 428 articles remained after the initial screening and were further screened based on the established inclusion and exclusion criteria. The efficacy of modified radical surgery and breast-conserving surgery in the treatment of early breast cancer was assessed by analyzing outcome indicators, including recurrence rate, distant metastatic rate, and three-year survival rate. The methods section details a systematic approach to data collection and analysis, specifying the databases and time frame for the literature search and the statistical tools used for the meta-analysis. The selection process, from the initial number of articles to the final inclusion based on defined criteria, is transparent, ensuring the study's methodological robustness in evaluating the efficacy of surgeries for early breast cancer. Results: Finally, ten articles were found to match the criteria and included in this study. According to the meta-analysis, there was no statistically significant difference between the breast-conserving therapy (BCT) and modified radical mastectomy (MRM) groups in terms of the recurrence rate (OR = 0.76, 95%CI = 0.39, 1.55, P > .05) and distant metastatic rate (OR = 0.81, 95%CI = 0.46, 1.31, P > .05). Nevertheless, the three-year survival rate was 85.2% in the BCT group and 91.7% in the MRM group; a statistically significant difference was observed in the three-year survival rate (OR = 1.47, 95%CI = 1.01, 2.37, P = .03) between the BCT and MRM groups. Accordingly, breast-conserving surgery and modified radical surgery produced comparable clinical outcomes for the treatment of early breast cancer. Conclusion: In the treatment of early breast cancer, breast-conserving surgery has the advantages of less bleeding, fewer clinical complications, and favorable cosmetic outcomes compared with modified radical surgery. Furthermore, patients with breast-conserving surgery showed comparable recurrence and distant metastatic rates to those with modified radical surgery in postoperative follow-up, which, therefore is a suitable treatment option for the widespread recommendation. The study's findings hold significant clinical relevance, implying that while BCT remains a viable option, MRM may offer a survival advantage. This insight empowers both patients and clinicians in making informed, personalized treatment decisions tailored to individual circumstances.
RESUMEN
Atherosclerosis, a multifaceted and persistent inflammatory condition, significantly contributes to the progression of cardiocerebrovascular disorders, such as myocardial infarctions and cerebrovascular accidents. It involves the accumulation of cholesterol, fatty deposits, calcium and cellular debris in the walls of arteries, leading to the formation of plaques. Our aim is to investigate the potential of sinomenine to counteract atherosclerosis in mice lacking Apolipoprotein E (ApoE-/-) Mice. We employed the high-fat diet-induced method to induce atherosclerosis in ApoE-/- mice, and the mice were treated with sinomenine (5, 10, and 15 mg/kg) and simvastatin (0.5 mg/kg) for 12 weeks. Body weight, water intake, and food intake were assessed. Lipid parameters, oxidative stress, inflammatory cytokines, and mRNA levels were estimated. Sinomenine treatment remarkably (P < 0.001) suppressed body weight, along with food and water intake. Sinomenine altered the levels of total cholesterol (TC), high-density lipoprotein (HDL), triglyceride (TG), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL), which were modulated in the atherosclerosis group. Sinomenine treatment also altered the levels of oxidative stress parameters such as glutathione peroxidase (GPx), catalase (CAT), malonaldehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH). In addition, it modulated cardiac parameters like C-reactive protein (CRP), endothelin-1 (ET-1), thromboxane B2 (TXB2), nitric oxide (NO), cardiac troponin I (cTnI), lactate dehydrogenase (LDH), and creatinine kinase isoenzymes (CK-MB). Inflammatory cytokines interleukin (IL)-1α, IL-1ß, TNF-α, IL-6, and IL-10 were also affected. Sinomenine further suppressed the mRNA expression of IL-6, IL-17, IL-10, tumor necrosis factor-α (TNF-α), Il-1ß, monocyte chemoattractant protein-1 (MCP-1), MCP-2, MCP-3, transforming Growth Factor-1ß (TGF-1ß), vascular cell adhesion molecule 1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1). The results suggest that sinomenine remarkably suppressed the development of atherosclerosis in the early stage.

The linearity of synaptic plasticity of single-walled carbon nanotube field-effect transistor (SWCNT FET) was improved by CdSe quantum dots decoration. The linearity of synaptic plasticity in SWCNT FET with decorating QDs was further improved by reducing the P-type doping level from the atmosphere. The synaptic behavior of SWCNT FET is found to be dominated by the charging and discharging processes of interface traps and surface traps, which are predominantly composed of H2O/O2redox couples. The improved synaptic behavior is mainly due to the reduction of the interface trap charging process after QDs decoration. The inherent correlation between the device synaptic behavior and the electron capture process of the traps are investigated through charging-based trap characterization. This study provides an effective scheme for improving linearity and designing new-type SWCNT synaptic devices.
RESUMEN
This paper reports a highly tunable photoelectric response of graphene field-effect transistor (GFET) with lateral P-N junction in channel. The poly(sulfobetaine methacrylate) (PSBMA) provides strong N-type doping on graphene due to the dipole moment of pendent groups after ultraviolet annealing in high vacuum. A lateral P-N junction is introduced into the channel of the GFET by partially covering the graphene channel with PSBMA. With such P-N junction in the channel, the GFET exhibits a highly tunable photoelectric response over a wide range of exciting photon wavelength. With a lateral P-N junction in the channel, the polarity of photocurrent (Iph) of the GFET switches three times as the back-gate voltage (VBG) scan over two Dirac-point voltages. The underlying physical mechanism of photoelectric response is attributed to photovoltaic and photo-induced bolometric effect, which compete to dominatingIphat variousVBG. This provides a possible strategy for designing new phototransistors or optoelectronic device in the future.
RESUMEN
BACKGROUND: Although previous studies have evaluated the prognostic role of the systemic immune-inflammation index (SII) in patients with breast cancer, the results were inconsistent. Therefore, in this context, we aimed to identify the prognostic and clinicopathological value of the SII in patients with breast cancer by performing a meta-analysis. METHODS: A literature search was using PubMed, Web of Science, EMBASE, and Cochrane Library databases for relevant articles, from their inception to May 12, 2020. The prognostic value of the SII in breast cancer was assessed by pooling the hazard ratios (HRs) with 95% confidence intervals (CIs). The clinical outcomes included the overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS), and distant metastasis-free survival (DMFS). The methodological quality of all the included studies was evaluated using the Newcastle-Ottawa quality assessment scale. The odds ratios (ORs) with 95% CIs were combined to evaluate the correlation between the SII and clinicopathological characteristics of patients with breast cancer. Publication bias was evaluated using the Begg funnel plot and the Egger linear regression test. All statistical analyses were performed using Stata software, version 12.0 (Stata Corporation, College Station, TX, USA). A p value of < 0.05 was considered statistically significant. RESULTS: Eight studies involving 2642 patients were included in the current meta-analysis. The combined data showed that patients with a high SII had worse OS (HR = 1.79, 95% CI 1.33-2.42, p < 0.001), poorer DFS/RFS (HR = 1.79, 95% CI 1.31-2.46, p < 0.001), and inferior DMFS (HR = 1.64, 95% CI 1.32-2.03, p < 0.001) than patients with a low SII. In addition, a high SII was correlated with the presence of lymph node metastasis (OR = 1.38, 95% CI 1.12-1.69, p = 0.002), higher T stage (OR = 1.49, 95% CI 1.17-1.89, p < 0.001), advanced TNM stage (OR = 1.37, 95% CI 1.07-1.77, p = 0.014), and higher histological grade (OR = 3.71, 95% CI 1.00-13.73, p = 0.049). However, there was no significant association between the SII and the pathological type (OR = 0.82, 95% CI 0.55-1.23, p = 0.345) or lymphatic invasion (OR = 1.30, 95% CI 0.82-2.08, p = 0.266). CONCLUSIONS: The results of our meta-analysis suggest that an elevated SII predicts poor survival outcomes and is associated with clinicopathological features that indicate tumor progression of breast cancer.
RESUMEN
The aprotic Li-O2 battery has attracted a great deal of interest because, theoretically, it can store far more energy than today's batteries. Toward unlocking the energy capabilities of this neotype energy storage system, noble metal-catalyzed high surface area carbon materials have been widely used as the O2 cathodes, and some of them exhibit excellent electrochemical performances in terms of round-trip efficiency and cycle life. However, whether these outstanding electrochemical performances are backed by the reversible formation/decomposition of Li2O2, i.e., the desired Li-O2 electrochemistry, remains unclear due to a lack of quantitative assays for the Li-O2 cells. Here, noble metal (Ru and Pd)-catalyzed carbon nanotube (CNT) fabrics, prepared by magnetron sputtering, have been used as the O2 cathode in aprotic Li-O2 batteries. The catalyzed Li-O2 cells exhibited considerably high round-trip efficiency and prolonged cycle life, which could match or even surpass some of the best literature results. However, a combined analysis using differential electrochemical mass spectrometry and Fourier transform infrared spectroscopy, revealed that these catalyzed Li-O2 cells (particularly those based on Pd-CNT cathodes) did not work according to the desired Li-O2 electrochemistry. Instead the presence of noble metal catalysts impaired the cells' reversibility, as evidenced by the decreased O2 recovery efficiency (the ratio of the amount of O2 evolved during recharge/that consumed in the preceding discharge) coupled with increased CO2 evolution during charging. The results reported here provide new insights into the O2 electrochemistry in the aprotic Li-O2 batteries containing noble metal catalysts and exemplified the importance of the quantitative assays for the Li-O2 reactions in the course of pursuing truly rechargeable Li-O2 batteries.
RESUMEN
High ionic conductive lithium niobium oxides were selected as the modifying material to investigate the effects on the electrochemical performances for host material LiNi1/3Co1/3Mn1/3O2 caused by the structure change of the modifying material at various calcination temperatures and modifying amounts. X-ray diffraction (XRD) studies revealed that the structure of the modifying material was single LiNbO3 phase after being calcined at 500 °C and changed to LiNbO3-Li3NbO4 mixture phases at 600 and 700 °C, and further changed to single Li3NbO4 phase at 800 °C. Electrochemical tests displayed that both LiNbO3 and Li3NbO4 phases of modifying material could contribute to the improvement of the cycle performances for the host material, but the improvement degree of Li3NbO4 phase was more evident. The cycle performances and high rate performances of the modified host material (calcined at 700 °C) electrodes were improved with the right modifying amount.
RESUMEN
Osteoarthritis (OA) is a common degenerative joint disease that disproportionately impacts the elderly population on a global scale. As aging is a significant risk factor for OA, there is a growing urgency to develop specific therapies that target the underlying mechanisms of aging associated with this condition. This summary seeks to offer a thorough introduction of ongoing research efforts aimed at developing therapies to combat senescence in the context of OA. Cellular senescence plays a pivotal role in both the deterioration of cartilage integrity and the perpetuation of chronic inflammation and tissue remodeling. Consequently, targeting SnCs has emerged as a promising therapeutic approach to alleviate symptoms and hinder the progression of OA. This review examines a range of approaches, including senolytic drugs targeting SnCs, senomorphics that modulate the senescence-associated secretory phenotype (SASP), and interventions that enhance immune system clearance of SnCs. Novel methodologies, such as utilizing novel materials for exosome delivery and administering anti-aging medications with precision, offer promising avenues for the precise treatment of OA. Accumulating evidence underscores the potential of targeting senescence in OA management, potentially facilitating the development of more effective and personalized therapeutic interventions.
RESUMEN
BACKGROUND: Childhood asthma is a chronic inflammatory disease of the respiratory tract characterized by bronchial inflammation, airway hyperresponsiveness, airflow disorder, and obstruction. Secreted frizzled-related protein 5 (SFRP5) may be associated with respiratory inflammatory diseases. This study investigated the effect of SFRP5 on human airway smooth muscle cells (HASMCs) to provide new ideas for treating asthma. METHODS: A total of 30 children with asthma and 30 children who had a physical examination at the same time were selected and divided into asthma and healthy groups. Serum SFRP5 levels were determined by enzyme-linked immunosorbent assay (ELISA) and real-time quantitative polymerase chain reaction (RT-qPCR). Lipofectamine 2000™ regent was used to transfect the SFRP5 overexpression plasmid (pc-SFRP5) or corresponding negative control (pc-NC) into HASMCs. HASMCs were treated with 10 µg/L platelet-derived growth factor-BB (PDGF-BB), which is an inducer to mimic the asthma-like condition at the cellular level of childhood asthma. HASMCs were divided into control, PDGF-BB (PDGF-BB treatment), PDGF-BB+pc-NC (pc-NC transfection and PDGF-BB treatment), and PDGF-BB+pc-SFRP5 (pc-SFRP5 transfection and PDGF-BB treatment) groups. Cell proliferation was measured by 5-ethynyl-2'-deoxyuridine (EdU) and cell counting kit-8 (CCK-8) assay. Cell migration was detected by Transwell assay. The protein expression was detected by western blot. RESULTS: Serum SFRP5 expression in the asthmatic group was decreased versus the healthy group (p < 0.0001). Induction of PDGF-BB decreased SFRP5 expression in HASMCs (p < 0.01). SFRP5 expression in the pc-SFRP5 group was increased (p < 0.01). The proliferation and migration of HASMCs increased after PDGF-BB treatment (p < 0.001, p < 0.0001), indicating that the asthma model was successfully inducted in vitro. Moreover, the expression of ß-catenin, cellular-myelocytomatosis viral oncogene (c-Myc), and cyclinD1 proteins in HASMCs increased after PDGF-BB treatment (p < 0.0001). SFRP5 overexpression partly inhibited PDGF-BB-induced proliferation, migration, and expressions of ß-catenin, c-Myc, and cyclinD proteins in HASMCs (p < 0.01, p < 0.001, p < 0.0001). CONCLUSIONS: Serum SFRP5 expression decreases in children with asthma. SFRP5 overexpression partially inhibits PDGF-BB-induced HASMC proliferation and migration by regulating the wingless-type mouse mammary tumor virus (MMTV) integration site family (Wnt)/ß-catenin pathway.

Despite the impressive specific capacity of Li-O2 batteries, challenges persist, particularly with lithium metal anode (LMA). These include dendritic growth and unstable solid electrolyte interface (SEI) layers, which become more pronounced in an oxygen-rich environment, a typical operation scenario for Li-O2 batteries. Herein, utilizing a hybrid dual anion electrolyte (DAE) strategy, which incorporates both inorganic LiNO3 and organic Li[(FSO2)(C2F5SO2)N] (LiFPFSI) salts, the dendritic growth is evidently inhibited by creating a "concrete-like" SEI structure. Simultaneously, it fosters the development of a fluorine-rich SEI layer. Consequently, a robust, compact, and stable barrier is formed, adeptly suppressing side reactions between LMA and the electrolyte, particularly those relevant to dissolved O2. The practicality and efficiency of this DAE strategy are validated across a variety of battery types including Li/Li, Li/Cu, and notably Li-O2 batteries, which showcased significantly improved reversibility and durability. These results underscore the important role of multifunctional salts in interphase engineering for LMA, which could lead to advancements in Li-O2 batteries.
RESUMEN
Objective: Allergic asthma is driven by an antigen-specific immune response. This study aimed to identify immune-related differentially expressed genes in childhood asthma and establish a classification diagnostic model based on these genes. Methods: GSE65204 and GSE19187 were downloaded and served as training set and validation set. The immune cell composition was evaluated with ssGSEA algorithm based on the immune-related gene set. Modules that significantly related to the asthma were selected by WGCNA algorithm. The immune-related differentially expressed genes (DE-IRGs) were screened, the protein-protein interaction network and diagnostic model of DE-IRGs was constructed. The pathway and immune correlation analysis of hub DE-IRGs was analyzed. Results: Eight immune cell types exhibited varying levels of abundance between the asthma and control groups. A total of 112 differentially expressed immune-related genes (DE-IRGs) was identified. Through the application of four ranking methods (MCC, MNC, DEGREE, and EPC), 17 hub DE-IRGs with overlapping significance were further selected. Subsequently, 8 optimized were identified using univariate logistic regression analysis and the LASSO regression algorithm, based on which a robust diagnostic model was constructed. Notably, TNF and CD40LG emerged as direct participants in asthma-related signaling pathways, displaying a positive correlation with the immune cell types of immature B cells, activated B cells, activated CD8 T cells, activated CD4 T cells, and myeloid-derived suppressor cells. Conclusion: The diagnostic model constructed using the DE-IRGs (CCL5, CCR5, CD40LG, CD8A, IL2RB, PDCD1, TNF, and ZAP70) exhibited high and specific diagnostic value for childhood asthma. The diagnostic model may contribute to the diagnosis of childhood asthma.
RESUMEN
Background: This study analyzed the risk factors associated with positive surgical margins (PSM) and five-year survival after prostate cancer resection to construct a positive margin prediction model. Methods: We retrospectively analyzed the clinical data of 148 patients treated with prostatectomy. The patients were divided into PSM group and Negative surgical margins (NSM) group. Several parameters were compared between the groups. All patients were followed up for 60 months. The risk factors for PSM and five-year survival were evaluated by univariate analysis, followed by multifactorial dichotomous logistic regression analysis. Finally, ROC curves were plotted for the risk factors to establish a predictive model for PSM after prostate cancer resection. Results: (1) Serum PSA, percentage of positive puncture stitches, clinical stage, surgical approach, Gleason score on puncture biopsy, and perineural invasion were significantly associated with the risk of PSM (P < 0.05). Serum PSA, perineural invasion, Gleason score on puncture biopsy, and percentage of positive puncture stitches were independent risk factors for PSM. (2) Total prostate-specific antigen (tPSA) by puncture, nutritional status, lymph node metastasis, bone metastasis, and seminal vesicle invasion may be risk factors for five-year survival. Lymph node metastasis and nutritional status were the main risk factors for the five-year survival of patients with prostate cancer. (3) After plotting the ROC curve, the area under the curve (AUC) [AUC: 0.776, 95%, confidence interval (CI): 0.725 to 0.854] was found to be a valid predictor of PSM; the AUC [AUC: 0.664, 95%, confidence interval (CI): 0.576 to 0.753] was also a valid predictor of five-year survival (P < 0.05). (4) The scoring system had a standard error of 0.02 and a cut-off value of 6. It predicted PSM after prostate cancer resection with moderate efficacy. Conclusions: Serum PSA, perineural invasion, puncture biopsy Gleason score, and percentage of positive puncture stitches were independent risk factors for positive surgical margins (PSM). Also, lymph node metastasis and nutritional status were the main risk factors for the five-year survival of patients with prostate cancer. Overall, the prediction efficacy of this scoring system concerning the risk of PSM after prostate cancer resection was moderate.

RESUMEN
OBJECTIVE: This study aimed to assess the diagnostic utility of spirometry, particularly focusing on small airway parameters, in children with cough variant asthma (CVA). METHODS: This study included children aged 5-12 years with a diagnosis of CVA. Pre- and postbronchodilation spirometry parameters, including FEV1 %pred, FVC%pred, FEV1 /FVC%pred, PEF%pred, FEF25 %pred, FEF50 %pred, FEF75 %pred, MMEF%pred, were recorded. Receiver operating characteristic curves were plotted, and the area under the curve (AUC) was calculated to assess the discriminatory potential of these spirometry parameters for CVA. A prediction model based on logistic regression (LR) was performed. RESULTS: A total of 200 patients with CVA and 73 control subjects were included. Baseline spirometry parameters in the CVA group, except for FVC%pred, were significantly lower compared to the control group. After inhalation of salbutamol sulfate, all parameters showed significant improvement in the CVA group. However, these parameters, except for FEV1 %pred and FVC%pred, remained lower in the CVA group compared to the control group. The improvement rate of each parameter in the CVA group, except for ∆ FVC%, was significantly higher than that in the control group. â³ MMEF% achieved the highest AUC of 0.797 with a threshold value of 16.09%, followed by â³ FEF75 % (0.792), â³ FEV1 % (0.756), and â³ FEF50 % (0.747) with threshold values of 19.01%, 4.48%, and 19.4%, respectively. The clinical prediction model included four variables (age, â³ FEF25 %, â³ FEF75 %, and â³ MMEF%) and demonstrated excellent performance distinguishing patients with and without CVA (AUC = 0.850). In the CVA group, the â³ FEV1 % showed a positive correlation with small airway parameters. CONCLUSIONS: This study highlights that children with CVA exhibit lower pulmonary function parameters compared to healthy children. Changes in small airway parameters during bronchodilator tests can be valuable in diagnosing CVA, and the LR prediction model incorporating age and several pulmonary parameters can assist physicians in accurately identifying CVA in clinical practice.

In the organic ligand, the dihedral angle between the benzene ring of the mesityl moiety and the imidazole ring is 76.99â (18)°. Weak intra-molecular C-Hâ¯Cl hydrogen-bonding inter-actions consolidate the mol-ecular conformation.
RESUMEN
Cardiovascular disease morbidity/mortality are increasing due to an aging population and the rising prevalence of diabetes and obesity. Therefore, innovative cardioprotective measures are required to reduce cardiovascular disease morbidity/mortality. The role of necroptosis in myocardial ischemia-reperfusion injury (MI-RI) is beyond doubt, but the molecular mechanisms of necroptosis remain incompletely elucidated. Growing evidence suggests that MI-RI frequently results from the superposition of multiple pathways, with autophagy, ferroptosis, and CypD-mediated mitochondrial damage, and necroptosis all contributing to MI-RI. Receptor-interacting protein kinases (RIPK1 and RIPK3) as well as mixed lineage kinase domain-like pseudokinase (MLKL) activation is accompanied by the activation of other signaling pathways, such as Ca2+/calmodulin-dependent protein kinase II (CaMKII), NF-κB, and JNK-Bnip3. These pathways participate in the pathological process of MI-RI. Recent studies have shown that inhibitors of necroptosis can reduce myocardial inflammation, infarct size, and restore cardiac function. In this review, we will summarize the molecular mechanisms of necroptosis, the links between necroptosis and other pathways, and current breakthroughs in pharmaceutical therapies for necroptosis.
RESUMEN
Due to ultrahigh theoretical capacity and ultralow redox poteneial, lithium metal is considered as a promising anode material. However, uneven lithium deposition, uncontrollable lithium dendrite formation, and fragile solid electrolyte interphase (SEI) lead to low lithium utilization, rapid capacity decay, and poor cycle performance. Herein, a robust artificial SEI film by coating the lithium surface with fibrous covalent organic framework (Fib-COF) was constructed, which effectively prevented dendrite penetration and battery short-circuits. Experimental results demonstrated that the Fib-COF-decorated batteries showcased higher Coulombic efficiency (CE), extended cycling stability, and superior electrolyte compatibility. The strong affinity of the carbonyl group in Fib-COF towards Li+ contributes to facilitating the Li+ uniform transfer and nucleation. In situ optical microscopy dynamically revealed the formation process of dendrite-free interphase under the function of Fib-COF layer. As a result, the modified Li anode demonstrated remarkable cycle stability for more than 650 h at 20 mA cm-2 and 5 mAh cm-2 in ether-based electrolyte and 1000 h at 0.5 mA cm-2 and 0.5 mAh cm-2 in carbonate-based electrolyte. The dendrite-free Fib-COF@Li electrodes endowed higher specific capacities of 650 mAh g-1 for Fib-COF@Li|S full cell after 250 cycles and 120 mAh g-1 for Fib-COF @Li|LiFePO4 full cells after 300 cycles.
