Preparation and characterization on the eco-friendly corn starch based adhesive of with salient water resistance, mildew resistance.

Starch adhesive is a commonly used bonding glue that is sustainable, formaldehyde-free and biodegradable. However, there are obviously some problems related to its high viscosity, poor water and mildew resistance. Hence, exploring a starch-based adhesive with good properties that satisfies the requirements of wood processing presents the context of the current research. Thus, corn starch was used as raw material to form oxidized starch (OCS) via oxidation using sodium periodate, it was reacted with a synthesis polyurea compound that prepared from hexanediamine-urea (HU) obtained by deamination to yield a oxidized starch-hexanediamine-urea adhesive (denoted hereafter as OCSHU). The oxidation process was optimized in terms of oxidant concentration, reaction time and temperature. Furthermore, the impact of HU addition on the mechanical properties of the adhesive was explored. Results indicate adhesive exhibited outstanding shear strength, when 13 % of NaIO4 was used as an oxidant to treat starch at 55 °C for 24 h, and involved in a subsequent reaction with 40 % of HU. The dry shear strength, 24 h cold water strength, 3 h hot water strength and 3 h boiling water strength are 1.84, 1.50, 1.32, and 1.31 MPa. Meantime, OCSHU adhesive solution revealed good storage stability whereas cured resin exhibited mildew resistance. The developed adhesive is a simple and green biomass wood adhesive.

Emerging Role of Interleukin-38 (IL-38) in the Development of Rheumatoid Arthritis.

INTRODUCTION: Rheumatoid arthritis (RA) is an incurable autoimmune disease. The role of interleukin-38 (IL-38), an anti-inflammatory cytokine, in RA is not fully understood, and its clinical relevance in RA remains unclear. This study aims to investigate the correlation of IL-38 with disease activity and the clinical manifestation of RA. METHODS: In this cross-sectional study, patients with treatment-naïve RA (n = 63) and healthy controls (HC) (n = 60) were consecutively enrolled over a 15-month period. Patients with RA were categorized into three subgroups-low disease activity (LDA), moderate disease activity (MDA) and high disease activity (HDA)-using the Disease Activity Score in 28 joints based on C-reactive protein (DAS28-CRP). Circulating levels of IL-38, tumour necrosis factor (TNF), IL-6, IL-17, IL-1ß, and 25(OH)D were assessed using enzyme-linked immunosorbent assay (ELISA). Clinical data, including duration, tender joints count (TJC), swollen joints count (SJC), patient global assessment (PGA), evaluator global assessment (EGA), bone mineral density (BMD), clinical disease activity index (CDAI), simplified disease activity index (SDAI), DAS28-CRP, joint musculoskeletal ultrasound (MSUS), and serological indicators were recorded. We determined the correlation between IL-38 and disease activity, as well as clinical manifestation in RA. RESULTS: At the macroscopic level, musculoskeletal ultrasonography of joints in different stages of disease activity in RA suggests that, as the disease progresses, arthritis in the hand becomes more severe, accompanied by synovial thickening and pronounced blood flow signals in the joint area. The expression of IL-38, TNF, IL-6, IL-17 and IL-1ß significantly increased in patients with RA compared to HC. Noteworthy differences were observed in the blood flow signal score, synovial signal score, IL-38, TNF, IL-6, IL-17 and IL-1ß among the three subgroups (LDA, MDA and HDA). As disease activity increased in patients with RA, the blood flow signal score, synovial signal score and expression of TNF, IL-6, IL-17 and IL-1ß exhibited a gradual increase, while the expression of IL-38 showed the opposite pattern. Inverse correlations were identified between IL-38 and pro-inflammatory cytokines (IL-6, IL-17), as well as key clinical parameters, including disease duration, SJC, TJC and DAS28-CRP score. CONCLUSION: IL-38, intricately linked to the pathogenesis of RA, emerges as a promising therapeutic target for the management of this debilitating disease.

A Mendelian randomization study on the causal relationship between smoking, alcohol consumption, and the development of myopia and astigmatism.

The influence of environmental factors like smoking and alcohol on myopia and astigmatism is controversial. However, due to ethical concerns, alternative study designs are urgently needed to assess causal inference, as mandatory exposure to cigarettes and alcohol is unethical. Following comprehensive screenings, 326 single nucleotide polymorphisms (SNPs) related to myopia and astigmatism were included in the dataset. To validate the causal association between exposures such as cigarette smoking, alcohol consumption, and coffee intake, and outcomes namely astigmatism and myopia, five regression models were employed. These models encompassed MR-Egger regression, random-effects inverse-variance weighted (IVW), weighted median estimator (WME), weighted model, and simple model. The instrumental variables utilized in these analyses were the aforementioned SNPs. Apply Cochran's Q test to determine heterogeneity of SNPs; if heterogeneity exists, focus on IVW model results. The IVW model showed a 1.379-fold increase in the risk of astigmatism (OR = 1.379, 95%CI 0.822~2.313, P = 0.224) and a 0.963-fold increase in the risk of myopia (OR = 0.963, 95%CI 0.666~1.393, P = 0.841) for each unit increase in smoking. For each unit increase in coffee intake, the risk of astigmatism increased 1.610-fold (OR = 1.610, 95%CI 0.444~5.835, P = 0.469) and the risk of myopia increased 0.788-fold (OR = 0.788, 95%CI 0.340~1.824, P = 0.578). For each additional unit of alcohol consumption, the risk of astigmatism increased by 0.763-fold (OR = 0.763, 95%CI 0.380~1.530, P = 0.446), and none of the differences were statistically significant. However, for each unit of alcohol consumption, the risk of myopia increased by 1.597 times, and the difference was statistically significant (OR = 1.597, 95%CI 1.023~2.493, P = 0.039). The findings indicate that alcohol consumption is a risk factor for myopia but smoking and coffee intake do not affect its development. Additionally, there is no association between smoking, alcohol consumption, coffee intake, and the risk of astigmatism.

Multimorbidity of Allergic Conditions in Urban Citizens of Southern China: A Real-World Cross-Sectional Study.

BACKGROUND: Extensive knowledge of allergic multimorbidities is required to improve the management of allergic diseases with the industrialization of China. However, the demography and allergen distribution patterns of allergic multimorbidities in China remain unclear, despite the increasing prevalence of allergies. METHODS: This was a real-world, cross-sectional study of 1273 outpatients diagnosed with one or more allergic diseases in Guangzhou, the most populated city of southern China, with leading industrial and commercial centers, between April 2021 and March 2022. Seven allergic diseases (allergic rhinitis (AR), asthma (AS)/cough variant asthma (CVA), atopic dermatitis (AD)/eczema, food allergy (FA), allergic conjunctivitis (AC), drug allergy (DA), and anaphylaxis) were assessed. Positive rates of sensitization to different allergens were measured using an allergen detection system of the UniCAP (Pharmacia Diagnostics, Sweden) instrument platform to compare the groups of allergic multimorbidities against a single entity. RESULTS: There were 659 (51.8%) males and 614 (48.2%) females aged from 4 months to 74 years included in the analysis. The study participants who were diagnosed with allergic diseases had an average of 1.6 diagnoses. Overall, 46.5% (592 of 1273) of the patients had more than one allergic condition, and allergic rhinitis was the most common type of multimorbidity. Women were more likely to suffer from an allergic disease alone, whereas allergic multimorbidities were more likely to be diagnosed in men (p = 0.005). In addition, allergic multimorbidities were common in all age groups, with an incidence ranging from 37.1% to 57.4%, in which children and adolescents were more frequently diagnosed with allergic multimorbidities than adults (18-60 years old) (all p < 0.05). Allergic multimorbidity was observed throughout the year. A difference in the positive rate of allergens sensitization and total immunoglobulin E (tIgE) levels between different allergic multimorbidities was observed. CONCLUSIONS: Allergic multimorbidities were very commonly found in nearly half of all patients with allergies. The proportion of allergic multimorbidities varied with the type of disease, sex, age, and allergen distribution pattern. These findings may help clinicians to develop "One health" strategies for the clinical management of allergic diseases.

COVID-19, Mental Health, Technology Use, and Job Satisfaction Among School Psychology Trainers.

The COVID-19 pandemic threatens to exacerbate the school psychology personnel crisis. There is a dearth of knowledge regarding how the pandemic has impacted school psychology trainers and course delivery. In this national study, 92 school psychology trainers completed an online questionnaire regarding technological instructional changes, job satisfaction, and their own mental health well-being during the pandemic. Findings suggest that during the portion of the pandemic assessed most trainers reported that they: (a) switched from in-person instruction to primarily online instruction, (b) were mostly satisfied with their jobs, and (c) generally experienced a positive sense of well-being. Furthermore, a sizable portion of those that switched to a mixture of hybrid and online instruction during the pandemic endorsed that they are likely to continue to use these modalities after the pandemic subsides. Unfortunately, although school psychology trainers presented as generally resilient workforce during the pandemic, almost 20% participants screened positive for possible depression.

Single-cell dissection of remodeled inflammatory ecosystem in primary and metastatic gallbladder carcinoma.

Gallbladder carcinoma (GBC) is the most common biliary tract malignancy with the lowest survival rate, primarily arising from chronic inflammation. To better characterize the progression from inflammation to cancer to metastasis, we performed single-cell RNA sequencing across samples of 6 chronic cholecystitis, 12 treatment-naive GBCs, and 6 matched metastases. Benign epithelial cells from inflamed gallbladders displayed resting, immune-regulating, and gastrointestinal metaplastic phenotypes. A small amount of PLA2G2A+ epithelial cells with copy number variation were identified from a histologically benign sample. We validated significant overexpression of PLA2G2A across in situ GBCs, together with increased proliferation and cancer stemness in PLA2G2A-overexpressing GBC cells, indicating an important role for PLA2G2A during early carcinogenesis. Malignant epithelial cells displayed pervasive cancer hallmarks and cellular plasticity, differentiating into metaplastic, inflammatory, and mesenchymal subtypes with distinct transcriptomic, genomic, and prognostic patterns. Chronic cholecystitis led to an adapted microenvironment characterized by MDSC-like macrophages, CD8+ TRM cells, and CCL2+ immunity-regulating fibroblasts. By contrast, GBC instigated an aggressive and immunosuppressive microenvironment, featured by tumor-associated macrophages, Treg cells, CD8+ TEX cells, and STMN1+ tumor-promoting fibroblasts. Single-cell and bulk RNA-seq profiles consistently showed a more suppressive immune milieu for GBCs with inflammatory epithelial signatures, coupled with strengthened epithelial-immune crosstalk. We further pinpointed a subset of senescence-like fibroblasts (FN1+TGM2+) preferentially enriched in metastatic lesions, which promoted GBC migration and invasion via their secretory phenotype. Collectively, this study provides comprehensive insights into epithelial and microenvironmental reprogramming throughout cholecystitis-propelled carcinogenesis and metastasis, laying a new foundation for the precision therapy of GBC.

Familial episodic pain syndrome: a case report and literature review.

The purpose of this case report and literature review is to show that familial episodic pain syndrome (FEPS) is a non-inflammatory genetically inherited pain syndrome. A 3-year-old boy presented at our hospital with pain in both his forearms and lower limbs below the knees for more than 3 years. There were no abnormalities in the blood tests, blood smears, liver and kidney function tests, trace elements tests, cellular immunity test, humoral immunity test, autoantibody tests, C-reactive protein (CRP) test, erythrocyte sedimentation rate (ESR) test, and tumor-related and bone marrow cytology examinations. Additionally, the imaging examination results showed no abnormalities. From the patient's medical history, we found that the mother of the child had a family history of a similar disease. To date, only 21 cases of FEPS3 caused by the sodium voltage-gated channel alpha subunit 11A (SCN11A) gene mutation have been reported. Although the age of onset is different, most of them are inherited in families. The results of the genetic examination revealed that the pain mainly came from the genetic inheritance of the maternal family line. The whole exon gene test revealed that the pain was caused by 2 heterozygous mutations of c.674G > T and c.671T > C in the SCN11A gene.

Skip-layer network with optimization method for domain adaptive detection.

In the field of object detection, domain adaptation is one of popular solution to align the distribution between the real scene (target domain) and the training scene (source domain) by adversarial training. However, only global features are applied to the Domain Adaptive Faster R-CNN (DA Faster R-CNN) method. The lack of local features reduces the performance of domain adaptation. Therefore, a novel method for domain adaptive detection called Skip-Layer Network with Optimization (SLNO) method is proposed in this paper. Three improvements are presented in SLNO. Firstly, different level convolutional features are fused by a multi-level features fusion component for domain classifier. Secondly, a multi-layer domain adaptation component is developed to align the image-level and the instance-level distributions simultaneously. Among this component, domain classifiers are used in both image-level and instance-level distributions through the skip layer. Thirdly, the cuckoo search (CS) optimization method is applied to search for the best coefficient of SLNO. As a result, the capability of domain alignment is strengthened. The Cityscapes, Foggy Cityscapes, SIM10K, KITTI data sets are applied to test our proposed novel approach. Consequently, excellent results are achieved by our proposed methods against state-of-the-art object detection methods. The results demonstrate our improvements are effective on domain adaptation detection.

Upending the shortages crisis: A national survey of school psychology recruitment.

School psychology is experiencing a shortages crisis. There is also lack of national data regarding current recruitment practices. Understanding these practices is essential to overcome these personnel shortages. In this national study, 151 school psychology programs within the US and its territories were surveyed. Participants were chosen from a national comprehensive list of school psychology programs compiled by the research team. The survey was created through a detailed review of relevant literature and distributed by email using Qualtrics. Various recruitment strategy domains were examined. Findings suggest that program representatives perceived program location to be most important and program cost the least important for students choosing their programs. Furthermore, respondents indicated a general consensus regarding the importance of establishing a recruitment pipeline. Moreover, programs within smaller communities appeared to be more involved in recruitment pipeline efforts. Descriptives for recruitment strategy domains are presented and implications are discussed.

Clinical efficacy of linagliptin combined with irbesartan in patients with diabetic nephropathy.

OBJECTIVE: To determine the clinical efficacy of linagliptin combined with irbesartan in patients with diabetic nephropathy (DN). METHODS: Seventy-two patients who were admitted to our department of endocrinology in our hospital during January 2018 and June 2019 were randomly divided into a control group (administered with irbesartan only, n=36) and a treatment group (treated with irbesartan and linagliptin, n=36). The course of treatment lasted for three months. FBG (fasting blood glucose), 2hPBG (2h postprandial blood sugar), HbA1C (hemoglobin A1c), Cys-C (cystatin C), SCr (serum creatinine), BUN (blood urea nitrogen), UACR (urine albumin-to-creatinine ratio), CRP (C-reactive protein), IL-6 (interleukin-6), and SOD (superoxide dismutase) were tested pre- and post-treatment to evaluate the clinical efficacy and adverse effects of the two treatment plans after three months of treatment. RESULTS: Compared with the pre-treatment levels, FBG, 2hPBG, HbA1c, Cys-C, SCr, BUN, UACR, CRP, IL-6, and SOD in both groups were significantly improved following the three-month treatment (P<0.05, respectively). Post-treatment levels of FBG, 2hPBG, HbA1c, Cys-C, SCr, BUN, UACR, CRP, and IL-6 in the treatment group were significantly lower than in the control group (P<0.05, respectively), while the treatment group exhibited a higher level of SOD compared with the control group (P<0.05). No serious adverse reaction occurred in either group (P>0.05). CONCLUSION: Combined-modality treatment with linagliptin and irbesartan shows favorable clinical efficacy in treating diabetic nephropathy as it effectively protects the kidneys and improves kidney function by inhibiting inflammatory and oxidative stress responses.

Patient-derived organoids for personalized gallbladder cancer modelling and drug screening.

BACKGROUND: Gallbladder carcinoma (GBC) is a relatively rare but highly aggressive cancer with late clinical detection and a poor prognosis. However, the lack of models with features consistent with human gallbladder tumours has hindered progress in pathogenic mechanisms and therapies. METHODS: We established organoid lines derived from human GBC as well as normal gallbladder and benign gallbladder adenoma (GBA) tissues. The histopathology signatures of organoid cultures were identified by H&E staining, immunohistochemistry and immunofluorescence. The genetic and transcriptional features of organoids were analysed by whole-exome sequencing and RNA sequencing. A set of compounds targeting the most active signalling pathways in GBCs were screened for their ability to suppress GBC organoids. The antitumour effects of candidate compounds, CUDC-101 and CUDC-907, were evaluated in vitro and in vivo. RESULTS: The established organoids were cultured stably for more than 6 months and closely recapitulated the histopathology, genetic and transcriptional features, and intratumour heterogeneity of the primary tissues at the single-cell level. Notably, expression profiling analysis of the organoids revealed a set of genes that varied across the three subtypes and thus may participate in the malignant progression of gallbladder diseases. More importantly, we found that the dual PI3K/HDAC inhibitor CUDC-907 significantly restrained the growth of various GBC organoids with minimal toxicity to normal gallbladder organoids. CONCLUSIONS: Patient-derived organoids are potentially a useful platform to explore molecular pathogenesis of gallbladder tumours and discover personalized drugs.

Multiple indicators of household dietary diversity in rural China: Effects of income and dietary knowledge.

OBJECTIVE: The aim of this study was to examine the association among family income, dietary knowledge, their interaction, and the multiple household dietary diversity indices (HDDIs), including dietary diversity score (DDS), entropy index (EI), Shannon equitability index (SEI), Herfindahl index (HI), and Simpson index (SI). METHODS: Based on 24-h dietary recall data collected from 1076 rural households in three provinces of Central China, we calculated HDDIs and compared them according to different levels of income and dietary knowledge. A set of multivariate linear regression were further established and estimated to examine the association among family income, dietary knowledge, and household dietary diversity. RESULTS: Although the calculation formulas are different, the distributions of the five diversity indices, namely, DDS, EI, SEI, HI, and SI are similar. Family income and dietary knowledge were significantly and positively correlated with various HDDIs (P < 0.01) in addition to HI. Specifically, with a 1-unit (10 000 yuan [US $1545]) income increase, the DDIs respectively changed by 1.70% (DDS), 1.23% (EI), 0.92% (SEI), -0.62% (HI, reverse), and 0.45% (SI). With a 1-point dietary knowledge score increase, the DDIs changed by 0.91% (DDS), 1.33% (EI), 1.29% (SEI), -1.19% (HI, reverse), and 0.81% (SI). The interaction effect of income and dietary knowledge on HDDIs were significantly and negatively correlated with various HDDIs (P < 0.05) in addition to HI. CONCLUSIONS: The present findings indicated that with an increase in income and dietary knowledge, rural residents in China would consume more diversified foods. There was a substitution effect of family income and dietary knowledge on HDDIs; that is, with an increase in family income, the effect of dietary knowledge on HDDIs would decrease. The findings of this study contributed to a better understanding of issues related to the dietary diversity of rural residents in China in the context of rising income and residents' increasing dietary knowledge.

Deep-Learning-Assisted multivariate curve resolution.

Gas chromatography-mass spectrometry (GC-MS) is one of the major platforms for analyzing volatile compounds in complex samples. However, automatic and accurate extraction of qualitative and quantitative information is still challenging when analyzing complex GC-MS data, especially for the components incompletely separated by chromatography. Deep-Learning-Assisted Multivariate Curve Resolution (DeepResolution) was proposed in this study. It essentially consists of convolutional neural networks (CNN) models to determine the number of components of each overlapped peak and the elution region of each compound. With the assistance of the predicted elution regions, the informative regions (such as selective region and zero-concentration region) of each compound can be located precisely. Then, full rank resolution (FRR), multivariate curve resolution-alternating least squares (MCR-ALS) or iterative target transformation factor analysis (ITTFA) can be chosen adaptively to resolve the overlapped components without manual intervention. The results showed that DeepResolution has superior compound identification capability and better quantitative performances when comparing with MS-DIAL, ADAP-GC and AMDIS. It was also found that baseline levels, interferents, component concentrations and peak tailing have little influences on resolution result. Besides, DeepResolution can be extended easily when encountering unknown component(s), due to the independence of each CNN model. All procedures of DeepResolution can be performed automatically, and adaptive selection of resolution methods ensures the balance between resolution power and consumed time. It is implemented in Python and available at https://github.com/XiaqiongFan/DeepResolution.

Innate lymphoid cells are increased in systemic lupus erythematosus.

OBJECTIVES: Innate lymphoid cells (ILCs) are emerging mediators of immunity and accumulation of inflammatory ILC populations can occur in inflammatory-mediated conditions. We aimed to examine the proportion of different subgroups of ILCs in the peripheral blood of patients with systemic lupus erythematosus (SLE) to evaluate the pathogenesis of SLE. METHODS: Peripheral blood mononuclear cells were collected from 51 SLE patients and 26 healthy controls. Subpopulations of ILCs were analysed by flow cytometry. RESULTS: Compared with the control group, ILCs (Lin-CD127+CD45+ cells) were higher in SLE patients (p<0.01), and the distribution of ILC population changed between groups, ILC1 (Lin-CD127+CD45+CRTH2-CD117-cells)/ILC3 (Lin-CD127+CD45+CRTH2-CD-117+cells) count increased (p<0.0001) and correlated with nephritis and disease activity. CONCLUSIONS: We found that SLE is accompanied by alterations in circulating ILCs. Specifically, circulating ILC1s and ILC3s were significantly increased, whereas circulating ILC2s were significantly decreased in SLE, indicating abnormal ILC homeostasis.

Hydromethanolic extract of Rehum emodi exhibits significant antimicrobial activity against acute gastroenteriti bacterial strains.

Rehum emodi is an important medicinal herbal and has been reported to exhibit tremendous pharmacological potential. The present study was designed to evaluate the antibacterial activity of hydromethanolic extract of rhizome of Rehum emodi against the acute gastroenteriti bacterial strains. The antimicrobial activity was determined by micro-dilution method. Antioxidant activity was determined by DPPH assay and cytotoxicity by MTT assay. Phytochemical analysis was carried out by LC/MS analysis. The results of the present study showed that hydromethanolic extract of rhizome of Rehum emodi (REE) exhibited significant antimicrobial activity against the gastroenteriti bacterial strains. The MIC values ranged from 25 µg/ml to 125 µg/ml. Moreover, the cytotoxicity of the REE was evaluated against the human breast cell line FR-2 and it was observed that REE exerted minimal cytotoxic effects on these cells with an IC50 of 250 µg/ml indicating that this extract is non-toxic to human cells. The phytochemical analysis revealed the presence of several secondery metabolites such as anthroquinones (anthrone, emodin, aloe emodin and rhein) flavonoids (quercetin, and naringenin) and phenolics (sinapinic acid and gallic acid) which could potentially be responsible for the activity of the extract. In conclusion REE could potentially prove to be useful in the treatment of acute gastroenteritis.

Associations of polymorphisms of rs693 and rs1042031 in apolipoprotein B gene with risk of breast cancer in Chinese.

BACKGROUND: Lipid synthesis is an integrated result of genetic, epigenetic and environmental factors, and also can promote growth and survival of cancer cells. Apolipoprotein B plays a central role in lipid metabolism as the major protein component of very-low-density lipoprotein and low-density lipoprotein. METHODS: We investigated the associations of polymorphisms of rs693 (-7673C>T) and rs1042031 (-12669 G>A) in the APOB gene with risk of breast cancer in 675 blood-unrelated Chinese patients with breast cancer and 712 healthy controls. RESULTS: Polymorphisms of -12669 G>A and -7673C>T in the APOB gene were significantly associated with an increased risk of breast cancer (P = 0.000), especially for postmenopausal women (P = 0.000, 0.023). The positive associations still remained after further analysis of the two polymorphisms' distribution according to body mass index. However, no statistical associations were found between -12669 G>A and -7673C>T polymorphisms and other clinical characteristics, including tumor size, lymph node metastasis, histological grade, estrogen and progesterone receptor status and Her-2 status. CONCLUSIONS: rs693 and rs1042031 polymorphisms in the APOB gene increased the risk of breast cancer in Chinese, and this role of the two polymorphisms in connection with breast cancer was not dependent on body mass index.
