RESUMO

WormBase has been the major repository and knowledgebase of information about the genome and genetics of C. elegans and other nematodes of experimental interest for over two decades. We have three goals: to keep current with the fast-paced C. elegans research, to provide better integration with other resources, and to be sustainable. Here we discuss the current state of WormBase as well as progress and plans for moving core WormBase infrastructure to the Alliance of Genome Resources (the Alliance). As an Alliance member, WormBase will continue to interact with the C. elegans community, develop new features as needed, and curate key information from the literature and large-scale projects.

RESUMO

Objective: To analyze the trends in literature related to oral microbiology and regenerative medicine from 2014 to 2023. By identifying key research countries, institutions, and their collaboration networks, as well as exploring research hotspots and development directions, the study seeks to provide references for researchers and decision-makers in the field of oral microbiology and regenerative medicine, thereby guiding the direction of future research. Methods: Relevant literature was retrieved using the Web of Science Core Collection database, with data processing and analysis conducted using CiteSpace 6.2.R6 software. Time slicing, node type selection, and the application of the g-index (g-index) were used for filtering, analyzing countries, institutions, authors, journals, and keywords. Results: The volume of literature in the field of oral microbiology and regenerative medicine has steadily increased from 2014 to 2023, with the number of publications first exceeding one hundred in 2020 and reaching 134 in 2022, accompanied by a citation frequency of 3 363 times. China and the United States have been at the forefront in terms of the volume of publications, while the United States and Germany lead in terms of intermediary centrality. The research primarily spans disciplines such as oral medicine, interdisciplinary studies, materials science, and immunology. High-frequency keywords include stem cells, scaffold materials, and gut microbiota, while cluster analysis indicates that inflammation, drug delivery, and antimicrobial activity remain consistent research themes. In recent years, the research heat in "tissue regeneration""gut microbiota " and "maxillofacial surgery" has risen, suggesting these may become focal points of future research. Conclusions: Over the past decade, the volume of literature published in the fields of oral microbiology and regenerative medicine, along with their citation frequencies, has increased annually. The research focus has shifted over time. Understanding the interactions between oral and gut microbiomes is crucial for developing innovative regenerative treatment strategies.

RESUMO

OBJECTIVE: Numerous investigations have indicated a correlation between air pollution (AP) and an elevated ischemic stroke (IS) likelihood. The existing literature does not provide a consensus about the possible link between AP and IS. A two-sample Mendelian randomization (MR) analysis was utilized to systematically measure the causal link between AP and ischemic stroke. Furthermore, the mediating impact of inflammatory factors was also performed by a two-step MR. MATERIALS AND METHODS: A two-sample MR analysis was utilized to examine the AP impact on the incidence of IS. Additionally, a two-step MR approach was carried out to account for possible mediating variables. The indirect impact was determined by employing the product approach, which included multiplying the AP impact on inflammatory factors by the inflammatory factors' impacts on IS. The MR effect was identified through inverse variance-weighted (IVW) meta-analysis of each Wald Ratio. Additionally, complementary studies were conducted using the weighted median and MR-egger approaches. RESULTS: The IVW method with random effects showed that the per unit increase in genetically predicted PM2.5 was linked to the 0.362-fold elevated ischemic stroke risk (OR: 1.362, 95% CI: 1.032-1.796, p=0.029). Furthermore, the IVM technique, incorporating random effects, demonstrated that the per unit increase in genetically predicted PM2.5 was related to an elevated Interleukin (IL)-1ß risk (OR: 1.529, 95% CI: 1.191-1.963, p=0.001), IL-6 (OR: 1.498, 95% CI: 1.094-2.052, p=0.012) and IL-17 (OR: 1.478, 95% CI: 1.021-2.139, p=0.038). IL-1ß, IL-6, and IL-17 modulated the PM2.5 impact on ischemic stroke, while the proportion mediated by them was 59.5%. CONCLUSIONS: A positive correlation between genetically predicted PM2.5 levels and elevated ischemic stroke risk is mediated by IL-1ß, IL-6, and IL-17.

RESUMO

Objective: To assess the association between body mass index (BMI) and major adverse cardiovascular and cerebrovascular events (MACCE) among patients with acute coronary syndrome (ACS). Methods: This was a multicenter prospective cohort study, which was based on the Improving Care for Cardiovascular Disease in China (CCC) project. The hospitalized patients with ACS aged between 18 and 80 years, registered in CCC project from November 1, 2014 to December 31, 2019 were included. The included patients were categorized into four groups based on their BMI at the time of admission: underweight (BMI<18.5 kg/m2), normal weight (BMI between 18.5 and 24.9 kg/m2), overweight (BMI between 25.0 and 29.9 kg/m2), and obese (BMI≥30.0 kg/m2). Multivariate logistic regression models was used to analyze the relationship between BMI and the risk of in-hospital MACCE. Results: A total of 71 681 ACS inpatients were included in the study. The age was (63.4±14.7) years, and 26.5% (18 979/71 681) were female. And the incidence of MACCE for the underweight, normal weight, overweight, and obese groups were 14.9% (322/2 154), 9.5% (3 997/41 960), 7.9% (1 908/24 140) and 7.0% (240/3 427), respectively (P<0.001). Multivariate logistic regression analysis showed a higher incidence of MACCE in the underweight group compared to the normal weight group (OR=1.30, 95%CI 1.13-1.49, P<0.001), while the overweight and obese groups exhibited no statistically significant difference in the incidence of MACCE compared to the normal weight group (both P>0.05). Conclusion: ACS patients with BMI below normal have a higher risk of in-hospital MACCE, suggesting that BMI may be an indicator for evaluating short-term prognosis in ACS patients.

RESUMO

Objective: To investigate the influence of disposable diaper dependence (DDD) on emotional behavior and related factors of preschool-aged children. Methods: A total of 3 000 preschool-aged children from 16 kindergartens in Zhengzhou of Henan Province from October 2019 to March 2020 were selected and their parents were investigated by using a basic information questionnaire (including usage of disposable diapers), Strengths and Difficulties Questionnaire (SDQ) and Children's Sleep Questionnaire (PSQ). The differences in baseline and clinical data were compared between the DDD children and normal children, and multiple linear regression models were used to analyze the factors associated with emotional behavior in DDD children. Results: A total of 3 000 questionnaires were distributed and 2 775 (92.50%) were valid. The children ranged in age from 3 to 5 years, including 1 438 boys (51.82%) and 1 337 girls (48.18%). There were 98 (3.53%) children in DDD group and 2 677 (96.47%) children in normal group. The proportion of children living in cities in the DDD group was 58.16%, significantly higher than that of 41.84% in the normal children group (P<0.001). The abnormal detection rate of various factors in SDQ in DDD children, from high to low, were hyperactivity (n=14, 14.29%), peer communication problems (n=12, 12.24%), prosocial behavior (n=11, 11.22%), emotional symptoms (n=10, 10.20%) and conduct problems (n=7, 7.14%). The detection rates of abnormal total difficulty scores in DDD group and normal children were 7.14% (7 cases) and 0.78% (21 cases), respectively, with statistically significant differences (P<0.001). The proportions of emotional symptoms and hyperactivity disorder in DDD group were higher than those in normal group, and the differences were statistically significant (P<0.05). The PSQ score of children in DDD group was 3.01±2.02 which was not significantly different from the PSQ score of the normal group (2.71±2.10, P=0.157). The multi-factor analysis showed that caregiver's education level (ß=-1.135,95%CI:-1.910 to -0.359), urinary incontinence (ß=2.222, 95%CI: 1.105-3.339), fecal incontinence (ß=3.833, 95%CI: 2.691-4.975), urinary and fecal incontinence (ß=5.522, 95%CI: 4.145-6.899), and recurrent urinary tract infections(ß=3.523,95%CI: 1.798-5.248)were the independent influencing factors of emotional behavioral problems in DDD children (P<0.05). Conclusions: Children with DDD are more likely to have emotional behavioral problems than normal children. Caregiver's education level, urinary incontinence and recurrent urinary tract infections were influencing factors of emotional behavioral problems in DDD children.

RESUMO

Chromothripsis, the process of catastrophic shattering and haphazard repair of chromosomes, is a common event in cancer. Whether chromothripsis might constitute an actionable molecular event amenable to therapeutic targeting remains an open question. We describe recurrent chromothripsis of chromosome 21 in a subset of patients in blast phase of a myeloproliferative neoplasm (BP-MPN), which alongside other structural variants leads to amplification of a region of chromosome 21 in ∼25% of patients ('chr21amp'). We report that chr21amp BP-MPN has a particularly aggressive and treatment-resistant phenotype. The chr21amp event is highly clonal and present throughout the hematopoietic hierarchy. DYRK1A , a serine threonine kinase and transcription factor, is the only gene in the 2.7Mb minimally amplified region which showed both increased expression and chromatin accessibility compared to non-chr21amp BP-MPN controls. We demonstrate that DYRK1A is a central node at the nexus of multiple cellular functions critical for BP-MPN development, including DNA repair, STAT signalling and BCL2 overexpression. DYRK1A is essential for BP-MPN cell proliferation in vitro and in vivo , and DYRK1A inhibition synergises with BCL2 targeting to induce BP-MPN cell apoptosis. Collectively, these findings define the chr21amp event as a prognostic biomarker in BP-MPN and link chromothripsis to a druggable target.

RESUMO

Plasma Position Reflectometry (PPR) is planned to provide plasma position and shape information for plasma operation in future fusion reactors. Its primary function is to calibrate the drift of the magnetic signals due to the integral nature of magnetic measurement. Here, we attempt to measure plasma position using ordinary mode (O-mode) and extraordinary mode (X-mode) reflectometry systems on two tokamaks. A new physical model based on the phase shift is proposed to deduce the relative movement of the cut-off layer without density inversion. We demonstrate the plasma position measurements by absolute measurement from density profile inversion and relative measurement from phase shift. The combination of X-mode and O-mode reflectometers can minimize the limitations of single polarization reflectometry and further increase the accuracy of plasma position measurement. These results could provide an important technical basis for the further development of a real-time control system based on PPR.

RESUMO

To investigate the value of 3D visualization reconstruction technology in pheochromocytoma/paraganglioma surgery.The clinical data of 87 patients with pheochromocytoma/paraganglioma admitted to the Department of Urology of Peking Union Medical College Hospital between January 2019 and December 2022 were retrospectively analyzed, and 3D visualization model reconstruction was performed preoperatively in 47 patients [Group A:males was 24 cases,the age M(Q1, Q3)42.00(30.00, 54.00)]. while the remaining 40 patients [Group B: males was 23 cases,the age M(Q1, Q3) 44.00(30.25, 53.75)] was not. The maximum tumor diameter, operation time, intraoperative bleeding, drain retention time and postoperative hospital stay were compared between the two groups. Surgery was successfully completed in both groups. 37 (78.7%) patients in group A underwent laparoscopic surgery, 7 (14.9%) patients underwent open surgery, and 3 (6.4%) patients underwent laparoscopic-to-open surgery. Thirty-one (77.5%) patients in group B underwent laparoscopic surgery, 5 (12.5%) patients underwent open surgery, and 4 (10.0%) patients underwent laparoscopic to open surgery. There was a difference in the maximum diameter of the tumor between the two groups [(6.09±3.02) cm vs (5.32±1.76) cm, P<0.05], the retention time of the drainage tube was significantly shorter in group A compared with group B [(3.20±1.38) d vs (4.02±1.98) d, P<0.05], and the length of the hospital stay after surgery was significantly shorter [(5.75±2.12) d vs (6.49±3.37) d, P<0.05]. Comparison of operation time and intraoperative bleeding between the two groups showed no statistically significant difference (P>0.05).Two cases of postoperative anemia and one case of pulmonary atelectasis in group B patients improved before discharge. Conclusion when the tumor diameter is>6 cm or has a close relationship with the surrounding organs and blood vessels, the use of 3D visual reconstruction technology can formulate and implement a more accurate and safe surgical plan, shorten the retention time of the drainage tube and postoperative hospitalization time, which is conducive to the patient's postoperative recovery and reduce postoperative complications.

RESUMO

OBJECTIVE: To evaluate the association of traditional Chinese medicine (TCM) treatment with the risk of readmission in patients with rheumatoid arthritis (RA) complicated with elevated platelet count. METHODS: We retrospectively collected the data of inpatients diagnosed with RA in our hospital from 2013 to 2021. The patients with elevated platelet count receiving TCM treatment were matched to those without TCM treatment using propensity score matching at the 1∶1 ratio, and the confounding factors were adjusted including gender, age, Chinese patent medicine, and external application. A Cox proportional hazard model was used to evaluate the hazard ratio (HR) of the risk of readmission, and a Kaplan-Meier curve was generated to assess the incidence of readmission in these patients. RESULTS: A total of 1176 RA patients with elevated platelet count were included in this study, including 842 patients in the TCM group and 334 patients in the non-TCM group, and after 1∶1 propensity score matching, 334 patients were included in each group. The Cox proportional hazards model showed that the readmission rate was significantly lower in TCM group than in non-TCM group (HR=0.59, 95% CI: 0.48-0.73, P<0.001), and TCM was a protective factor against readmission in RA patients with elevated platelet count. Kaplan-Meier curves demonstrated that long-term use of TCM helped to decrease the risk of readmission (Log-rank P<0.001). Association rules showed that the use of several Chinese herbal medicines and the Chinese patent medicine Xinfeng Capsule had a strong correlation with improvement of such clinical indicators as rheumatoid factor, erythrocyte sedimentation rate, and C-reactive protein. CONCLUSION: In RA patients with elevated platelet count, the use of TCM, as a protective factor against readmission, is strongly associated with a lowered risk of readmission with a long-term association.

RESUMO

A 105 GHz collective Thomson scattering (CTS) diagnostic has been successfully developed for fast-ion measurements on the HL-2A tokamak, and it has been deployed during an experimental campaign. Enhanced signals exhibiting synchronous modulation characteristics have been observed across all CTS channels upon the launch of a modulated probe wave. Results show that the intensity of the CTS signal increases with Neutral Beam Injection (NBI) power and is proportional to neutron count, indicating that the scattering signal contains a contribution from fast ions. Compared with the signal without NBI, the enhanced scattering spectrum due to NBI is slightly wider than the predicted fast ion range. Such broadening might be attributed to the heating effects of the gyrotron.

RESUMO

Semen is a measure of the reproductive efficiency of roosters, which affects the economic benefits of white-feathered broilers. Over the years, research in this field has mainly focused on hens, while there have been fewer studies on the reproductive traits of roosters. To identify the genes related to the semen traits of roosters, we used a chicken 55 K SNP chip to genetically type the white-feathered population (220) and performed imputation with resequencing data from 97 roosters. In total, 1 048 576 SNPs were obtained and used for genome-wide association analysis of semen volume, from which 197 genome-wide significant markers were identified, all within the interval of 13.82-16.12 Mb on chromosome 7. By combining our results with the biological functions of genes in the interval, four candidate genes were identified that potentially relate to semen volume: FAPP1, OSBPL6, SESTD1 and SSFA2. Our findings may provide a basis for further research on the genetic mechanism and marker-assisted selection of semen volume in white-feathered broilers.

RESUMO

OBJECTIVE: The aim of this study was to explore the effect of Ezetimibe combined with Simvastatin in the treatment of coronary heart disease (CHD). PATIENTS AND METHODS: Clinical data of 101 patients with CHD, admitted to our hospital from February 2022 to May 2023, were retrospectively analyzed. Among them, 49 patients received Simvastatin (Simvastatin group), and 52 patients received Simvastatin+Ezetimibe (Simvastatin+Ezetimibe group). Levels of blood lipid indicators, inflammatory factors, cardiac function indicators, and incidences of major adverse cardiovascular events (MACE) between the two groups were compared before and after the treatment. RESULTS: After the treatment, high-density lipoprotein cholesterol (HDL-C), cardiac index (CI), and left ventricular ejection fraction (LVEF) in both groups were higher than those before the treatment, and overall higher in the Simvastatin+Ezetimibe group. Levels of low-density lipoprotein-cholesterol (LDL-C), triglycerides (TG), total cholesterol (TC), monocyte chemoattractant protein-1 (MCP-1), chemokine ligand 19 (CCL19), high sensitivity C-reactive protein (hs-CRP), cardiac output (CO) in the two groups were lower than before the treatment. These indexes were significantly lower in the Simvastatin+Ezetimibe group (p<0.05) compared to the Simvastatin group. During the treatment, the incidence of MACE in the Simvastatin+Ezetimibe group (3.85%) was significantly lower than that in the Simvastatin group (16.33%) (p<0.05). CONCLUSIONS: Compared with Simvastatin alone, a combination of Ezetimibe and Simvastatin can more effectively regulate the level of blood lipids, reduce the inflammatory reaction in the body, improve heart function, and lower the risk of MACE.

RESUMO

Grp94 is the endoplasmic reticulum paralog of the hsp90 family of chaperones, which have been targeted for therapeutic intervention via their highly conserved ATP binding sites. The design of paralog-selective inhibitors relies on understanding the structural elements that mediate each paralog's response to inhibitor binding. Here, we determined the structures of Grp94 and Hsp90 in complex with the Grp94-selective inhibitor PU-H36, and of Grp94 with the non-selective inhibitor PU-H71. In Grp94, the 8-aryl moiety of PU-H36 is inserted into Site 2, a conditionally available side pocket, but in Hsp90 it occupies Site 1, a non-selective side pocket that is accessible in all hsp90 paralogs. The structure of Grp94 in complex with the non-selective PU-H71 shows only Site 1 binding. Large conformational shifts involving helices 1, 4 and 5 of the N-terminal domain of Grp94 are associated with the engagement of the Site 2 pocket for ligand binding. To understand the origins of Site 2 pocket engagement, we tested the binding of Grp94-selective ligands to chimeric Grp94/Hsp90 constructs. These studies show that helix 1 of the Grp94 N-terminal domain is the discriminating element that allows for remodeling of the ATP binding pocket and exposure of the Site 2 selective pocket.

RESUMO

Background: Exercise has been reported as an effective intervention for Parkinson's disease. However, there is still debate on the what kinds of exercises prior to choosing. This study aimed to compare and rank the different exercises that effectively enhance postural balance in Parkinson's disease patients by quantifying the information gleaned from randomized controlled trials (RCTs). Methods: We conducted a comprehensive database search, including PubMed, Cochrane Library, Embase, Web of Science, and PsycINFO. The included studies were evaluated for methodological quality by the Cochrane Risk of Bias tool. Results: The RCTs were collected between the earliest available date and March 2023. Sixty RCTs were included and the total sample size used in the study was 3,537. Thirty-five studies were defined as low risk of bias, twenty-one studies as medium risk of bias, and four studies as high risk of bias. The network meta-analysis results showed that exergaming exercise can significantly improve patients' Timed-Up-and-Go time (SUCRA = 91.5%). Dance can significantly enhance patients' Berg Balance Scale (surface under the cumulative ranking curve, SUCRA = 81.3%), and rhythmical auditory exercise can significantly improve patients' Mini-Balance Evaluation Systems Test score (SUCRA = 95.6%). Conclusion: Compared with other exercises, exergaming exercise, Dance, and rhythmical auditory exercise showed superior efficacy in improving postural balance among Parkinson's disease patients.

RESUMO

BACKGROUND: Age prediction powered by artificial intelligence (AI) can be used as an objective technique to assess the cosmetic effect of rejuvenation surgery. Existing age-estimation models are trained on public datasets with the Caucasian race as the main reference, thus they are impractical for clinical application in Chinese patients. METHODS: To develop and select an age-estimation model appropriate for Chinese patients receiving rejuvenation treatment, we obtained a face database of 10 529 images from 1821 patients from the author's hospital and selected two representative age-estimation algorithms for the model training. The prediction accuracies and the interpretability of calculation logic of these two facial age predictors were compared and analyzed. RESULTS: The mean absolute error (MAE) of a traditional support vector machine-learning model was 10.185 years; the proportion of absolute error ≤6 years was 35.90% and 68.50% ≤12 years. The MAE of a deep-learning model based on the VGG-16 framework was 3.011 years; the proportion of absolute error ≤6 years was 90.20% and 100% ≤12 years. Compared with deep learning, traditional machine-learning models have clearer computational logic, which allows them to give clinicians more specific treatment recommendations. CONCLUSION: Experimental results show that deep-learning exceeds traditional machine learning in the prediction of Chinese cosmetic patients' age. Although traditional machine learning model has better interpretability than deep-learning model, deep-learning is more accurate for clinical quantitative evaluation. Knowing the decision-making logic behind the accurate prediction of deep-learning is crucial for deeper clinical application, and requires further exploration.

RESUMO

OBJECTIVES: Lockdown was implemented in many countries during the pandemic, which led to myriad changes in pregnant women's lives. However, the potential impacts of the COVID-19 pandemic on neonatal outcomes remain unclear. We aimed to evaluate the association between the pandemic and neonatal birth weight. STUDY DESIGN: This was a systematic review and meta-analysis of the previous literature. METHODS: We searched the MEDLINE and Embase databases up to May 2022 and extracted 36 eligible studies that compared neonatal birth weight between the pandemic and the prepandemic period. The following outcomes were included: mean birth weight, low birth weight (LBW), very low birth weight (VLBW), macrosomia, small for gestational age (SGA), very small for gestational age (VSGA), and large for gestational age (LGA). Statistical heterogeneity among studies was assessed to determine whether a random effects model or fixed effects model was conducted. RESULTS: Of the 4514 studies identified, 36 articles were eligible for inclusion. A total of 1,883,936 neonates during the pandemic and 4,667,133 neonates during the prepandemic were reported. We identified a significant increase in mean birth weight (pooled mean difference [95% confidence interval (CI)] = 15.06 [10.36, 19.76], I2 = 0.0%, 12 studies) and a reduction in VLBW (pooled OR [95% CI] = 0.86 [0.77, 0.97], I2 = 55.4%, 12 studies). No overall effect was identified for other outcomes: LBW, macrosomia, SGA, VSGA, and LGA. There was publication bias for mean birth weight with a borderline significance (Egger's P = 0.050). CONCLUSION: Pooled results showed the pandemic was significantly associated with an increase in mean birth weight and a reduction in VLBW, but not for other outcomes. This review provided clues about the indirect effects of the pandemic on neonatal birth weight and more healthcare measures needed to improve neonatal long-term health.

RESUMO

Objective: To explore the method and effect of endoscopic assisted functional rhinoplasty for patients with deviated nose and deviated nasal septum, which achieve correction of nasal morphology and ventilation dysfunction. Methods: The clinical data of 226 patients with deviated nose and deviated nasal septum from June 2009 to February 2022 who were treated by endoscopic assisted functional rhinoplasty in the Affiliated Hospital of Qingdao University were analyzed retrospectively. There were 174 males and 52 females, with the age ranging from 7 to 67 years old. The effect was evaluated by subjective and objective evaluation methods. SPSS 27.0 software was used for statistical analysis. Results: All patients were followed up for 6 to 24 months, 174 cases were cured (174/226, 76.99%), 52 cases were effective (52/226, 23.01%), and the total effective rate was 100% (226/226). The difference between preoperative and postoperative facial appearance deviation was statistically significant ((6.84±2.25)mm vs (1.82±1.05)mm, t=38.94, P<0.001), and the nasal ventilation function of all patients was improved. Conclusions: Endoscopic assisted functional rhinoplasty for the patients with deviated nose combined with deviated nasal septum has the advantages of clear surgical field, fewer complications, and good result. It can achieve the purpose of simultaneous correction of nasal and ventilation dysfunction, which is recommended for popularizing in clinical application.
