Exploring the comprehensive link between climatic factors and vegetation productivity in China.

Understanding the influence of climatic factors on vegetation dynamics and cumulative effects is critical for global sustainable development. However, the response of vegetation to climate and the underlying mechanisms in different climatic zones remains unclear. In this study, we analyzed the response of vegetation gross primary productivity (GPP) to climatic factors and the cumulative effects across various vegetation types and climatic zones, utilizing data on precipitation (Pr), temperature (Ta), and the standardized precipitation evapotranspiration index (SPEI). The results showed that: (1) GPP showed significant differences among the seven climatic zones, with the highest value observed in zone VII, reaching 1860.07 gC·m- 2, and the lowest in zone I, at 126.03 gC·m- 2. (2) GPP was significantly and positively correlated with temperature in climatic zones I, IV, V, and VI and with precipitation in climatic zones I, II, and IV. Additionally, a significant positive correlated was found between SPEI and GPP in climatic zones I, II, and IV. (3) Drought exerted a cumulative effect on GPP in 45.10% of the regions within China, with an average cumulative duration of 5 months. These effects persisted for 6-8 months in zones I, II, and VII, and for 2-4 months in zones III, IV and VI. Among different vegetation types, forests experienced longest cumulative effect time of 6 months, followed by grasslands (5 months), croplands (4 months), and shrublands (4 months). The cumulative time scale decreased with increasing annual SPEI. The varying responses and accumulation of GPP to drought among different vegetation types in various climatic zones underscore the complexity of vegetation-climate interactions the response and accumulation of GPP to drought.

Impact of narrative nursing cognition, self-efficacy, and social support on the practices of registered nurses in China: a structural equation modeling analysis.

BACKGROUND: Narrative nursing is a novel approach according with humanistic care, which has been shown to be effective in improving health outcomes for both patients and nurses. Nevertheless, few studies have investigated the status of narrative nursing practice among nurses, and a comprehensive understanding of factors influencing this practice remains elusive. DESIGN: This was an observational, cross-sectional study using convenience sampling method. METHODS: After obtaining the informed consent, a total of 931 registered nurses from three hospitals in China were investigated. Data were collected using the Social Support Rating Scale, the General Self-efficacy Scale, and the Knowledge-Attitude-Practice Survey of Clinical Nurses on Narrative Nursing. All the scales were validated in the Chinese population. The questionnaire results were verified by an independent investigator. Factors influencing narrative nursing practice were determined through a series of analyses, including independent sample t-tests, one-way ANOVA, and Pearson correlations. Subsequently, path analysis was performed and a structural equation model was established. RESULTS: The score of narrative nursing practice in this study was 30.26 ± 5.32. The structural equation model showed a good fit, with a Root Mean Square Error of Approximation (RMSEA) of 0.007 (90%CI: 0.000, 0.047). Both social support and narrative nursing attitude could directly affect narrative nursing practice (ßsocial support = 0.08, P < 0.001; ßattitude = 0.54, P < 0.001) and indirectly influence it via self-efficacy (ßsocial support = 0.04, P < 0.001; ßattitude = 0.06, P < 0.001). In addition, narrative nursing knowledge (ß = 0.08, P < 0.001) and the nurses' growth environment (ß=-0.06, P < 0.001) also affected the practice of narrative nursing. CONCLUSION: Narrative nursing in China is at a medium level and could be influenced by several personal and environmental factors. This study highlighted the critical role of nursing management in the advancement of narrative nursing practices. Nurse managers should prioritize specialized training and cultivate supportive environments for nurses to improve their narrative nursing practices.

Identification of zinc finger MIZ-type containing 2 as an oncoprotein enhancing NAD-dependent protein deacetylase sirtuin-1 deacetylase activity to regulate Wnt and Hippo pathways in non-small-cell lung cancer.

BACKGROUND: Zinc finger MIZ-type containing 2 (ZMIZ2) can function as a coactivator and participate in the progression of certain malignant tumors; however, its expression and underlying molecular mechanism in non-small-cell lung cancer (NSCLC) remains unknown. In this study, we aim to analyze the expression of ZMIZ2 and its tumorigenic function in NSCLC, identifying its related factors. METHODS: ZMIZ2 expression in NSCLC tissue samples and cell lines was examined using immunohistochemistry and western blotting; its biological role was investigated using in vivo and in vitro assays. The association between ZMIZ2 and NAD-dependent protein deacetylase sirtuin-1 (SIRT1) was demonstrated using mass spectrometry and immunoprecipitation experiments. Kyoto Encyclopedia of Genes and Genomes Pathway (KEGG)-based enrichment analysis, luciferase reporter assay, and real-time quantitative polymerase chain reaction (RT-qPCR) were conducted to verify the impact of ZMIZ2-SIRT1 combination on Hippo/Wnt pathways. RESULTS: ZMIZ2 was highly expressed in NSCLC and positively associated with advanced pTNM staging, lymph node metastasis, and poor overall survival. Functional experiments revealed that ZMIZ2 promotes the proliferation, migration, and invasiveness of lung cancer cells-establishing its role as a promoter of oncogenes. Molecular mechanism studies identified SIRT1 as an assisted key factor interacting with ZMIZ2. KEGG enrichment analysis revealed that ZMIZ2 is closely related to Wnt/Hippo pathways; ZMIZ2-SIRT1 interaction enhanced SIRT1 deacetylase activity. Direct downregulation of intranuclear ß-catenin and yes-associated protein (YAP) acetylation levels occurred independently of upstream proteins in Wnt/Hippo pathways; transcriptional activities of ß-catenin-transcription factor 4 (TCF4) and YAP-TEA domain family transcription factors (TEADs) were amplified. CONCLUSIONS: ZMIZ2 promotes the malignant phenotype of lung cancer by regulating Wnt/Hippo pathways through SIRT1, providing an experimental basis for discovering novel biomarkers and developing tumor-targeted drugs.

[Inflammatory factors and prostate cancer: Two-sample Mendelian randomization analysis].

OBJECTIVE: To evaluate the potential causal relationship between inflammatory factors and PCa using the two-sample Mendelian randomization (MR) method. METHODS: We selected summary statistics of genome-wide association studies (GWAS) (n = 14 824) on 91 inflammatory factors, with PCa as the outcome in the latest 9th edition of FinnGen database for MR analysis. We evaluated the causal relationship between inflammatory factors and PCa using the odds ratio (OR) and 95% confidence interval (CI) of such regression models as inverse variance weighting (IVW), MR-Egger regression, simple mode (SM), weighted mode (WM) and weighted median estimator (WME), with IVW as the main statistical method for this study. We further verified the results of MR by Bayesian analysis, and evaluated the heterogeneity of genetic instrumental variables, pleiotropic effects and sensitivity of single nucleotide polymorphisms (SNP) as instrumental variables to the exposure-outcome relationship by Cochran's Q test, MR-Egger intercept test and leave-one-out cross validation. RESULTS: IVW showed that among the 91 inflammatory factors, interleukin-22 receptor A1 (IL-22RA1) and sulfotransferase 1A1 (ST1A1) were correlated positively with the risk of PCa； IL-22RA1：IVW（OR ［95% CI］: 1.12 ［1.00－1.25］, P = 0.04）；ST1A1：IVW（OR ［95% CI］: 1.08 (1.00－1.16), P = 0. 03）, while Chemokine ligand 11 (CXCL11) and interleukin 17 A (IL-17 A) negatively with the risk of PCa； CXCL11：IVW（OR ［95% CI］: 0.88 ［0.81－0.95］, P = 0.00）；IL-17A：IVW（OR ［95% CI］: 0.91 ［0.84－0.98］, P = 0.02）. No potential horizontal pleiotropy was detected by MR-Egger intercept analysis (P > 0.05, IL-22RA1 = 0.885, ST1A1 = 0.949, CXCL11 = 0.391, IL-17A = 0.884), nor biased SNPs in the MR pleiotropy residual sum and outlier (MR-PRESSO) test (P > 0.05, IL-22RA1 = 0.479, ST1A1 = 0.629, CXCL11 = 0.326, IL-17A = 0.444), or heterogeneity P > 0.05, IL-22RA1 = 0.543, ST1A1 = 0.677, CXCL11 = 0.336, IL-17A = 0.494). Leave-one-out sensitivity analysis indicated no significant impact of individual SNP sites on the overall causal relationship prediction, suggesting the reliable results of analysis. CONCLUSION: Among the 91 inflammatory factors, IL-22RA1 and ST1A1 have a positive causal relationship, while CXCL11 and IL-17A have a negative causal relationship with PCa.

[Methodological and reporting quality of randomized controlled trials on the treatment of benign prostatic hyperplasia with traditional Chinese medicine].

OBJECTIVE: To systematically evaluate the methodological quality and reporting quality of randomized controlled trials (RCT) on the treatment of BPH with traditional Chinese medicine (TCM), in order to provide some methodological reference for clinical practice and research. METHODS: We searched CNKI, VIP, Wanfang Data and PubMed for RCTs on the treatment of BPH with TCM published in China from January 2013 to November 2023. Two researchers screened the literature separately, and evaluated the methodological and reporting quality of the RCTs based on the Cochrane bias risk assessment tool and CONSORT TCM compound. RESULTS: Totally, 88 RCTs were included in this study. In terms of methodological quality, according to the Cochrane bias risk assessment tool, 27 biases in the process of randomization were identified as of low-risk and the other 61 of a certain risk. Among the allocation-related biases deviating from the established interventions, 76 were of low risk, 10 of a certain risk and 2 of high risk; among the compliance-related biases deviating from the established interventions, 76 were of low risk and 12 of a certain risk; among the biases due to missing outcome data, 86 were of low risk and 2 of a certain risk, while all the biases due to outcome measurement were of low risk; and among the biases from selective reporting, 65 were of low-risk, 2 of a certain risk and 21 of high-risk. In terms of reporting quality, according to the evaluation criteria of consort TCM compound, appropriate key words were used in 1 RCT (0.01%), the random assignment sequence method described in 27 (30.68%), the details of assignment limitation given in 5 (5.68%), assignment concealment mentioned in 3 (3.41%), the blind method and assignment concealment employed in 3 (3.41%), fall-offs recorded in 10 (11.36%), adverse events reported in 38 (43.18%), and limitations of the trials analyzed in 18 (20.45%). All the RCTs lacked complete intervention measures, subject flow chart, clinical trial registration and research schemes. CONCLUSION: At present, the methodological quality and reporting quality of RCTs on the treatment of BPH with TCM are generally low, with the main problems of incomplete experimental designs, lack of detailed description of randomized and blind methods, and insufficient TCM symptom evaluation of outcome indicators. Researchers should be cautious in adopting and applying the results reported, follow the CONSORT statement in design, registration, implement and reporting of the scheme, fully consider the clinical characteristics of TCM in the treatment of BPH, and reasonably design and report the evaluation indicators.

WNT5B promotes the malignant phenotype of non-small cell lung cancer via the FZD3-DVL3-RAC1-PCP-JNK pathway.

The WNT5B ligand regulates the non-canonical wingless-related integration site (WNT)-planar cell polarity (PCP) pathway. However, the detailed mechanism underlying the activity of WNT5B in the WNT-PCP pathway in non-small cell lung cancer (NSCLC) is unclear. In this study, we assessed the clinicopathological significance of WNT5B expression in NSCLC specimens. WNT5B-overexpression and -knockdown NSCLC cell lines were generated in vivo and in vitro, respectively. WNT5B overexpression in NSCLC specimens correlates with advanced tumor node metastasis (TNM) stage, lymph node metastasis, and poor prognosis in patients with NSCLC. Additionally, WNT5B promotes the malignant phenotype of NSCLC cells in vivo and in vitro. Interactions were identified among WNT5B, frizzled3 (FZD3), and disheveled3 (DVL3) in NSCLC cells, leading to the activation of WNT-PCP signaling. The FZD3 receptor initiates DVL3 recruitment to the membrane for phosphorylation in a WNT5B ligand-dependent manner and activates c-Jun N-terminal kinase (JNK) signaling via the small GTPase RAC1. Furthermore, the deletion of the DEP domain of DVL3 abrogated these effects. Overall, we demonstrated a novel signal transduction pathway in which WNT5B recruits DVL3 to the membrane via its DEP domain through interaction with FZD3 to promote RAC1-PCP-JNK signaling, providing a potential target for clinical intervention in NSCLC treatment.

Association of healthy lifestyle factors and genetic liability with bipolar disorder: Findings from the UK Biobank.

BACKGROUND: The interplay between genetic and lifestyle factors in the development of bipolar disorder (BD) remains unclear. METHODS: A cohort study was carried out on 365,517 participants from the UK Biobank. Lifestyle scores, based on smoking, physical activity, diet, alcohol consumption, sedentary behavior, sleep duration, and social contact, were grouped as favorable (scores 6-7), intermediate (scores 4-5), or unfavorable (scores 0-3). The BD polygenic risk score (PRS) was also categorized into high, intermediate, and low-risk groups using PRS tertiles. Cox regression models determined hazard ratios (HRs) and 95 % confidence intervals (CIs) for BD. RESULTS: During the 12.9-year follow-up, 529 individuals developed BD. Comparing those with favorable lifestyles to those with unfavorable participants, the HR of developing BD was 3.28 (95 % CI, 2.76-3.89). Similarly, individuals with a high PRS had a risk of 3.20 (95 % CI, 2.83-3.63) compared to those with a low PRS. Notably, individuals with both a high PRS and an unfavorable lifestyle had a significantly higher risk of BD (HR = 6.31, 95 % CI, 4.14-9.63) compared to those with a low PRS and a favorable lifestyle. Additionally, the interaction between PRS and lifestyle contributed an additional risk, with a relative excess risk of 1.74 (95 % CI, 0.40-3.07) and an attributable proportion due to the interaction of 0.37 (95 % CI, 0.16-0.58). CONCLUSIONS: Our findings suggest that genetic liability for BD, measured as PRS, and lifestyle have an additive effect on the risk of developing BD. A favorable lifestyle was associated with a reduced risk of developing BD.

[Formation Mechanism and Source Apportionment of Hydrochemical Components in Groundwater in the Yinchuan Plain].

Groundwater is one of the major water sources for production, living, and agricultural irrigation in the Yinchuan Plain. Owing to the influence of the regional environmental background and long-term effects of human activities, groundwater quality is generally inferior. To deeply analyze the formation mechanism and source of hydrochemical components in groundwater in the Yinchuan Plain, the traditional hydrochemical graphic method and mathematical statistics and principal component analysis-multivariate linear statistical model were used. Based on inorganic component contents of 100 phreatic water samples and 46 confined groundwater samples, the hydrochemical characteristics and quality status, spatial distribution of over-limit toxicological components, and contribution rate of hydrochemical components were analyzed. The results showed that the chemical components of groundwater were controlled by rock weathering and evaporation concentration. Dissolution-enrichment （F1）, original geological environment （F2）, and human activities（F3） were the principal factors that influenced groundwater hydrochemistry with the contribution rates of 73.67%, 14.45%, and 11.88%, respectively. The major over-limit toxicity indices in groundwater were NO3--N and F-. High NO3--N phreatic water was mainly influenced by agriculture activities, followed by the discharge of domestic sewage. Enrichment of groundwater F- was mainly caused by leaching of F-bearing minerals and cation exchange adsorption.

Protective effects of fermented Rosa roxburghii Tratt juice against ethanol­induced hepatocyte injury by regulating the NRF2­AMPK signaling pathway in AML­12 cells.

Alcohol­related liver disease (ALD) is a major health concern worldwide. In recent years, there has been growing interest in natural products and functional foods for preventing and treating ALD due to their potential antioxidant and hepatoprotective properties. Rosa roxburghii Tratt, known for its rich content of bioactive compounds, has demonstrated promising health benefits, including anti­inflammatory and antioxidant effects. Fermentation has been utilized as a strategy to enhance the bioavailability and efficacy of natural products. In the present study, using a mixture of Rosa roxburghii Tratt juice, lotus leaf extract and grape seed proanthocyanidins fermented by Lactobacillus plantarum HH­LP56, a novel fermented Rosa roxburghii Tratt (FRRT) juice was discovered that can prevent and regulate ethanol­induced liver cell damage. Following fermentation, the pH was significantly decreased, and the content of VC and superoxide dismutase (SOD) were significantly increased, along with a noticeable enhancement in hydroxyl and 2,2­diphenyl­1­picrylhydrazyl free radical scavenging abilities. Alpha Mouse liver 12 cells were exposed to ethanol for 24 h to establish an in vitro liver cell injury model. The present study evaluated the effects of FRRT on cell damage, lipid accumulation and oxidative stress markers. The results revealed that FRRT pretreatment (cells were pre­treated with 2.5 and 5 mg/ml FRRT for 2 h) significantly reduced lipid accumulation and oxidative stress in liver cells. Mechanistically, FRRT regulated lipid metabolism by influencing key genes and proteins, such as AMP­activated protein kinase, sterol regulatory element binding transcription factor 1 and Stearyl­CoA desaturase­1. Furthermore, FRRT enhanced antioxidant activity by increasing SOD activity, glutathione and catalase levels, while reducing reactive oxygen species and malondialdehyde levels. It also reversed the expression changes of ethanol­induced oxidative stress­related genes and proteins. In conclusion, a novel functional food ingredient may have been discovered with extensive potential applications. These findings indicated that FRRT has antioxidant properties and potential therapeutic benefits in addressing ethanol­induced liver cell damage through its effects on liver lipid metabolism and oxidative stress.

A detailed analysis of 16S rRNA gene sequencing and conventional PCR-based testing for the diagnosis of bacterial pathogens and discovery of novel bacteria.

This study represents the first analysis of the bacterial community in chickens affected by swollen head syndrome, utilizing 16S rRNA gene sequencing. Samples were obtained from clinical laying chickens and were examined for the presence of Avibacterium paragallinarum (APG) and Ornithobacterium rhinotracheale (ORT) using conventional polymerase chain reaction (PCR). From the samples, five APG-positive (APG) and APG-negative (N-APG) samples were chosen, along with five specific pathogen-free chickens, for 16S rRNA gene sequencing. Results showed that APG and ORT were widely detected in the chicken samples with swollen head syndrome (SHS, 9/10), while APG was detected in all five specific pathogen-free (SPF) samples. In contrast, conventional PCR sensitivity was found to be inadequate for diagnosis, with only 35.7% (5/14) and 11.1% (1/9) sensitivity for APG and ORT, respectively, based on 16S rRNA gene sequencing data. Furthermore, 16S rRNA gene sequencing was able to quantify the bacteria in the samples, revealing that the relative abundance of APG in the APG group ranged from 2.7 to 81.3%, while the relative abundance of APG in the N-APG group ranged from 0.1 to 21.0%. Notably, a low level of APG was also detected in all 5 SPF samples. The study also identified a significant number of animal and human common bacterial pathogens, including but not limited to Gallibacterium anatis, Riemerella columbina, Enterococcus cecorum, Mycoplasma synoviae, Helicobacter hepaticus, and Staphylococcus lentus. In conclusion, 16S rRNA gene sequencing is a valuable tool for bacterial pathogen diagnosis and the discovery of novel bacterial pathogens, while conventional PCR is not reliable for diagnosis.

BHAFT: Bayesian heredity-constrained accelerated failure time models for detecting gene-environment interactions in survival analysis.

In addition to considering the main effects, understanding gene-environment (G × E) interactions is imperative for determining the etiology of diseases and the factors that affect their prognosis. In the existing statistical framework for censored survival outcomes, there are several challenges in detecting G × E interactions, such as handling high-dimensional omics data, diverse environmental factors, and algorithmic complications in survival analysis. The effect heredity principle has widely been used in studies involving interaction identification because it incorporates the dependence of the main and interaction effects. However, Bayesian survival models that incorporate the assumption of this principle have not been developed. Therefore, we propose Bayesian heredity-constrained accelerated failure time (BHAFT) models for identifying main and interaction (M-I) effects with novel spike-and-slab or regularized horseshoe priors to incorporate the assumption of effect heredity principle. The R package rstan was used to fit the proposed models. Extensive simulations demonstrated that BHAFT models had outperformed other existing models in terms of signal identification, coefficient estimation, and prognosis prediction. Biologically plausible G × E interactions associated with the prognosis of lung adenocarcinoma were identified using our proposed model. Notably, BHAFT models incorporating the effect heredity principle could identify both main and interaction effects, which are highly useful in exploring G × E interactions in high-dimensional survival analysis. The code and data used in our paper are available at https://github.com/SunNa-bayesian/BHAFT.

Lab-on-a-chip: an advanced technology for the modernization of traditional Chinese medicine.

Benefiting from the complex system composed of various constituents, medicament portions, species, and places of origin, traditional Chinese medicine (TCM) possesses numerous customizable and adaptable efficacies in clinical practice guided by its theories. However, these unique features are also present challenges in areas such as quality control, screening active ingredients, studying cell and organ pharmacology, and characterizing the compatibility between different Chinese medicines. Drawing inspiration from the holistic concept, an integrated strategy and pattern more aligned with TCM research emerges, necessitating the integration of novel technology into TCM modernization. The microfluidic chip serves as a powerful platform for integrating technologies in chemistry, biology, and biophysics. Microfluidics has given rise to innovative patterns like lab-on-a-chip and organoids-on-a-chip, effectively challenging the conventional research paradigms of TCM. This review provides a systematic summary of the nature and advanced utilization of microfluidic chips in TCM, focusing on quality control, active ingredient screening/separation, pharmaceutical analysis, and pharmacological/toxicological assays. Drawing on these remarkable references, the challenges, opportunities, and future trends of microfluidic chips in TCM are also comprehensively discussed, providing valuable insights into the development of TCM.

Effects and mechanisms of sciadonic acid on colonic transit function through regulating 5-HT4/cAMP/PKA/AQP4 signaling pathway in STC model mice.

Torreya grandis (T. grandis) oil has been reported to alleviate symptoms of slow transit constipation (STC). However, the impact of sciadonic acid (SA), a distinctive fatty acid found in T. grandis oil, on the pathological progression of STC remains unclear. This study aimed to evaluate the effect of SA on STC and uncover the underlying mechanisms. The STC model was established by feeding Balb/c mice with loperamide. After 2 weeks of intervention, SA significantly improved weight loss and intestinal motility decline induced by STC, along with enhancing plasma indices and reducing colon pathological damage. SA effectively reversed the STC-induced decrease in the 5-HT4/cAMP/PKA/AQP4 signaling pathway genes and expression. Furthermore, 16S rRNA analysis demonstrated that SA mitigated the imbalance of the intestinal microbiota induced by STC, by reducing the ratio of Firmicutes to Bacteroidetes (F/B) and increasing the abundance of beneficial bacteria such as Akkermansia. In conclusion, SA intervention alleviated colonic dysfunction in STC mice. The activation of the SA-mediated 5-HT4/cAMP/PKA/AQP4 signaling pathway may serve as a potential target for STC treatment. These findings suggest that SA holds promise as a treatment option for STC and could potentially be extended to other related gut diseases for further investigation.

Intrinsic Capacity, Polygenic Risk Score, APOE Genotype, and Risk of Dementia: A Prospective Cohort Study Based on the UK Biobank.

BACKGROUND AND OBJECTIVES: The World Health Organization recently released a novel metric for healthy aging: intrinsic capacity (IC). The relationship between IC and the incidence of dementia, and its subtypes, is unknown. We aimed to analyze the relationship between IC and the incidence of dementia and its subtypes. Moreover, we tested whether genetic susceptibility to dementia could be modified by IC. METHODS: This cohort study involved 366,406 participants from the UK Biobank between 2006 and 2010. We analyzed 7 factors that reflected functional status across 4 IC domains to compute a comprehensive IC deficit score. Cox models were used to elucidate the relationship between the IC deficit score and the incidence of dementia. RESULTS: Among the 366,406 participants, 5,207 cases of dementia were documented, encompassing 2,186 and 1,175 cases of Alzheimer disease (AD) and vascular dementia (VD), respectively. Compared with participants with an IC score of 0, individuals with an IC score of 4+ had a markedly elevated risk of dementia (hazard ratio [HR] 2.17, 95% CI 1.92-2.45). In the joint analysis, for participants with a high polygenic risk score (PRS) and an IC score of 4 or more, the HR of all-cause dementia was 8.11 (95% CI 6.28-10.47) compared with individuals with a low PRS and an IC score of 0. Similar results were seen in the AD and VD groups. DISCUSSION: In summary, IC is associated with a higher risk of dementia, particularly in those combined with genetically predisposed to dementia.

DEKR-SPrior: An Efficient Bottom-Up Keypoint Detection Model for Accurate Pod Phenotyping in Soybean.

The pod and seed counts are important yield-related traits in soybean. High-precision soybean breeders face the major challenge of accurately phenotyping the number of pods and seeds in a high-throughput manner. Recent advances in artificial intelligence, especially deep learning (DL) models, have provided new avenues for high-throughput phenotyping of crop traits with increased precision. However, the available DL models are less effective for phenotyping pods that are densely packed and overlap in in situ soybean plants; thus, accurate phenotyping of the number of pods and seeds in soybean plant is an important challenge. To address this challenge, the present study proposed a bottom-up model, DEKR-SPrior (disentangled keypoint regression with structural prior), for in situ soybean pod phenotyping, which considers soybean pods and seeds analogous to human people and joints, respectively. In particular, we designed a novel structural prior (SPrior) module that utilizes cosine similarity to improve feature discrimination, which is important for differentiating closely located seeds from highly similar seeds. To further enhance the accuracy of pod location, we cropped full-sized images into smaller and high-resolution subimages for analysis. The results on our image datasets revealed that DEKR-SPrior outperformed multiple bottom-up models, viz., Lightweight-OpenPose, OpenPose, HigherHRNet, and DEKR, reducing the mean absolute error from 25.81 (in the original DEKR) to 21.11 (in the DEKR-SPrior) in pod phenotyping. This paper demonstrated the great potential of DEKR-SPrior for plant phenotyping, and we hope that DEKR-SPrior will help future plant phenotyping.

Association between residential greenness and incident delirium: A prospective cohort study in the UK Biobank.

BACKGROUND: Contemporary environmental health investigations have identified green space as an emerging factor with promising prospects for bolstering human well-being. The incidence of delirium increases significantly with age and is fatal. To date, there is no research elucidating the enduring implications of green spaces on the occurrence of delirium. Therefore, we explored the relationship between residential greenness and the incidence of delirium in a large community sample from the UK Biobank. METHODS: Enrollment of participants spanned from 2006 to 2010. Assessment of residential greenness involved the land coverage percentage of green space within a buffer range of 300 m and 1000 m. The relationship between residential greenness and delirium was assessed using the Cox proportional hazards model. Further, we investigated the potential mediating effects of physical activity, particulate matter (PM) with diameters ≤2.5 (PM2.5), and nitrogen oxides (NOx). RESULTS: Of 232,678 participants, 3722 participants were diagnosed with delirium during a 13.4-year follow-up period. Compared with participants with green space coverage at a 300 m buffer in the lowest quartile (Q1), those in the highest quartile (Q4) had 15 % (Hazard ratio [HR] = 0.85, 95 % confidence interval [CI]: 0.77, 0.94) lower risk of incident delirium. As for the 1000 m buffer, those in Q4 had a 16 % (HR = 0.84, 95 % CI: 0.76, 0.93) lower risk of incident delirium. The relationship between green space in the 300 m buffer and delirium was mediated partially by physical activity (2.07 %) and PM2.5(49.90 %). Comparable findings were noted for the green space percentage within the 1000 m buffer. CONCLUSIONS: Our results revealed that long-term exposure to residential greenness was related to a lower risk of delirium. Air pollution and physical activity exerted a significant mediating influence in shaping this association.

[A multicenter study of neonatal stroke in Shenzhen, China]. / 深圳市新生儿脑卒中多中心现况调查.

OBJECTIVES: To investigate the incidence rate, clinical characteristics, and prognosis of neonatal stroke in Shenzhen, China. METHODS: Led by Shenzhen Children's Hospital, the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022. The incidence, clinical characteristics, treatment, and prognosis of neonatal stroke in Shenzhen were analyzed. RESULTS: The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137, 1/6 060, and 1/7 704, respectively. Ischemic stroke accounted for 75% (27/36); boys accounted for 64% (23/36). Among the 36 neonates, 31 (86%) had disease onset within 3 days after birth, and 19 (53%) had convulsion as the initial presentation. Cerebral MRI showed that 22 neonates (61%) had left cerebral infarction and 13 (36%) had basal ganglia infarction. Magnetic resonance angiography was performed for 12 neonates, among whom 9 (75%) had involvement of the middle cerebral artery. Electroencephalography was performed for 29 neonates, with sharp waves in 21 neonates (72%) and seizures in 10 neonates (34%). Symptomatic/supportive treatment varied across different hospitals. Neonatal Behavioral Neurological Assessment was performed for 12 neonates (33%, 12/36), with a mean score of (32±4) points. The prognosis of 27 neonates was followed up to around 12 months of age, with 44% (12/27) of the neonates having a good prognosis. CONCLUSIONS: Ischemic stroke is the main type of neonatal stroke, often with convulsions as the initial presentation, involvement of the middle cerebral artery, sharp waves on electroencephalography, and a relatively low neurodevelopment score. Symptomatic/supportive treatment is the main treatment method, and some neonates tend to have a poor prognosis.

Development and evaluation of guar gum-coated nano-nutriosomes for cyanidin-3-O-glucoside encapsulation.

Cyanidin-3-O-glucoside (C3G) is a type of water-soluble flavonoid compound that is abundantly found in fruits and vegetables. C3G possesses numerous biological activities, however, it is prone to breakdown under environmental conditions. To overcome these issues, we developed nano-nutriosome (NS) carriers created by vortex-mixing and probe-sonication techniques for C3G encapsulation in which the phospholipid and Nutriose® FB06 were chosen as carrier material, and guar gum (GG) as a coating material to formulate a unilamellar and multicompartment structure. This study aimed to develop and evaluate C3G-loaded nano-nutriosomes coated by GG (GG-C3G-NS) for improving physicochemical stability, antioxidant activity, cellular uptake, and controlled release properties. The C3G-NS and GG-C3G-NS are nanosized (143.47 to 154.13 nm), with high encapsulation efficiency (>93.31 %). The NS carriers successfully encapsulated C3G which was confirmed by transmission electron microscopy, differential scanning calorimetry, and Fourier transform infrared spectroscopy. C3G showed more stability in storage, thermal, pH, ionic, and oxidative conditions. Furthermore, the NS exhibited a better-controlled release of C3G in different food stimulant conditions and in vitro release study. Additionally, NS systems enhanced cellular uptake and showed no cytotoxicity. Overall, GG-NS could be a promising nanocarrier for improving the stability, controlled release, and antioxidant activity of bioactive compounds.

Dynamic process of ecosystem water use efficiency and response to drought in the Yellow River Basin, China.

Ecosystem water use efficiency (WUE) is a crucial indicator of the impact of climate change on terrestrial ecosystems, reflecting the balance between biological processes (photosynthesis and transpiration) and physical processes (evapotranspiration). However, the response mechanisms and driving processes of WUE to drought remain to be further understood. In this study, we analyzed the spatial and temporal dynamics and response mechanisms of WUE in the Yellow River Basin (YRB) using data on Gross Primary Productivity (GPP), Evapotranspiration (ET) and Standardized Precipitation Evapotranspiration Index (SPEI), which revealed the cumulative effect of drought on WUE and assessed the ecosystem's resilience. The study results showed that (1) GPP, ET and WUE in the YRB exhibited a significant increasing trend, with 63.04 % of the area showing a marked increase in WUE. (2) GPP was the dominant factor influencing WUE in 65.36 % of the area, particularly in cropland and grassland, while ET was more influential in forested areas. Vapor pressure deficit (VPD) was identified as the principal driver affecting vegetation GPP in semi-arid and semi-humid regions of the YRB. In contrast, soil moisture (SM) was the limiting factor in arid areas. (3) 71.00 % of the WUE in the basin was affected by drought cumulative effects, with an average cumulative duration of 4.5 months. Arid regions experienced the most extended duration of 7.29 months, compared to 3.05 months in semi-humid regions. (4) 74.85 % of the regional ecosystems exhibited ecological resilience to drought, particularly in the source areas of the western basin of the YRB. Shrublands have the highest drought resilience among vegetation types, while grasslands have the lowest. The resilience of each climatic zone was in the order of semi-humid, semi-arid, and arid order. This study comprehensively analyzed of the spatial and temporal dynamics and response mechanisms of WUE in the YRB, offering a new perspective and scientific basis for understanding and predicting the ecosystem response to climate change.

Operando Building of a Superior Interface Hybrid Film Enables Chemomechanically Durable Co-Free Ni-Rich Cathodes.

The Co-free Ni-rich layered cathodes become pivotal to reduce cost and increase benefit toward next-generation Li-ion batteries yet raise a major challenge for their extremely fragile cathode-electrolyte interface (CEI) film. Herein, we report the in situ construction of the Si/B-enriched organic-inorganic hybrid CEI films on LiNi0.9Mn0.1O2 (NM91) with the assistance of tris(trimethylsilyl) borate (TMSB) additive. The hybrid film exhibits superior Young's modulus, mechanical strength, and ductility, which greatly dissipate the microstrain of Co-free Ni-rich cathodes under various states of charge with high structural integrity. Furthermore, the surface oxygen anions have been significantly stabilized by bonding with the Si and B ions of TMSB with high safety. These merits enable a durable Co-free Ni-rich layered cathode with 96.9% and 87.7% capacity retentions (versus 72.7% and 70.2% of NM91) at a high rate of 5C and a high-temperature of 55 °C after 100 cycles. In a pouch-type full cell, 88.8% of initial capacity is still maintained after cycling at 1C for 500 times, greatly expediting the development and application of Co-free Ni-rich layered cathodes.
