RESUMO

BACKGROUND: Although periodontitis is reportedly associated with increased cognitive decline in Alzheimer's disease, the mechanisms underlying this process remain unknown. Porphyromonas gingivalis lipopolysaccharide (P.g-LPS) is an endotoxin associated with periodontal disease. OBJECTIVE: We investigated the effect of periodontitis on learning capacity and memory of amyloid-ß protein precursor (AßPP)/presenilin (PS1) transgenic mice along with the mechanisms underlying these effects. METHODS: Mice were randomly assigned to three groups, namely AßPP/PS1 (control), P.g-LPS Injection, and P.g-LPS Injection + Ligation. Mice from the P.g-LPS Injection group were injected with P.g-LPS in the periodontal tissue three times per week for 8 weeks, while mice from the P.g-LPS Injection + Ligation group were injected with P.g-LPS and subjected to ligation of the gingival sulcus of the maxillary second molar. RESULTS: Expression of gingival proinflammatory cytokines as well as alveolar bone resorption in P.g-LPS-injected and ligatured mice was increased compared to that in control mice. Mice in the P.g-LPS Injection + Ligation group exhibited cognitive impairment and a significant reduction in the number of neurons. Glial cell activation in the experimental groups with significantly increased amyloid-ß (Aß) levels was more pronounced relative to the control group. Induction of periodontitis was concurrent with an increase in cyclooxygenase-2, inducible nitric oxide synthase, AßPP, and beta-secretase 1 expression and a decrease in A disintegrin and metalloproteinase domain-containing protein 10 expression. CONCLUSION: These findings indicated that periodontitis exacerbated learning and memory impairment in AßPP/PS1 mice and augmented Aß and neuroinflammatory responses. Our study provides a theoretical basis for risk prediction and early intervention of Alzheimer's disease and periodontitis.

RESUMO

In practice, charts are widely stored as bitmap images. Although easily consumed by humans, they are not convenient for other uses. For example, changing the chart style or type or a data value in a chart image practically requires creating a completely new chart, which is often a time-consuming and error-prone process. To assist these tasks, many approaches have been proposed to automatically extract information from chart images with computer vision and machine learning techniques. Although they have achieved promising preliminary results, there are still a lot of challenges to overcome in terms of robustness and accuracy. In this paper, we propose a novel alternative approach called Chartem to address this issue directly from the root. Specifically, we design a data-embedding schema to encode a significant amount of information into the background of a chart image without interfering human perception of the chart. The embedded information, when extracted from the image, can enable a variety of visualization applications to reuse or repurpose chart images. To evaluate the effectiveness of Chartem, we conduct a user study and performance experiments on Chartem embedding and extraction algorithms. We further present several prototype applications to demonstrate the utility of Chartem.

RESUMO

BACKGROUND: Tetracentron sinense is an endemic and endangered deciduous tree. It belongs to the Trochodendrales, one of four early diverging lineages of eudicots known for having vesselless secondary wood. Sequencing and resequencing of the T. sinense genome will help us understand eudicot evolution, the genetic basis of tracheary element development, and the genetic diversity of this relict species. RESULTS: Here, we report a chromosome-scale assembly of the T. sinense genome. We assemble the 1.07 Gb genome sequence into 24 chromosomes and annotate 32,690 protein-coding genes. Phylogenomic analyses verify that the Trochodendrales and core eudicots are sister lineages and showed that two whole-genome duplications occurred in the Trochodendrales approximately 82 and 59 million years ago. Synteny analyses suggest that the γ event, resulting in paleohexaploidy, may have only happened in core eudicots. Interestingly, we find that vessel elements are present in T. sinense, which has two orthologs of AtVND7, the master regulator of vessel formation. T. sinense also has several key genes regulated by or regulating TsVND7.2 and their regulatory relationship resembles that in Arabidopsis thaliana. Resequencing and population genomics reveals high levels of genetic diversity of T. sinense and identifies four refugia in China. CONCLUSIONS: The T. sinense genome provides a unique reference for inferring the early evolution of eudicots and the mechanisms underlying vessel element formation. Population genomics analysis of T. sinense reveals its genetic diversity and geographic structure with implications for conservation.

RESUMO

The ultrasound (US) imaging technique has been applied to scoliosis assessment, and the proxy Cobb angle can be acquired on the US coronal images. The spinous process angle (SPA) is a valuable parameter to indicate three-dimensional (3-D) deformity of spine. However, the SPA cannot be measured on ultrasound images since the spinous process (SP) is merged in the soft tissue layer and impossible to be identified on the coronal view directly. A new method based on gradient vector flow (GVF) snake model was proposed to automatically locate SP position on the ultrasound transverse images, and the density-based spatial clustering of application with noise (DBSCAN) was used to remove the outliers out of the detected location results. With marking the SP points on the ultrasound coronal image, the SP curve was interpolated and the SPA was measured. The algorithm was evaluated on 50 subjects with various severity of scoliosis, and two raters measured the SPA on both US images and radiographs manually. The mean absolute differences (MAD) of SPAs obtained from the two modalities were 3.4±2.4° and 3.6±2.8° for two raters respectively which was less than the clinical acceptance error (5°), and the results reported a good linear correlation (r>0.85) between ultrasound method and radiography. It indicates that the proposed method can be a promising approach for SPA measurement using the ultrasound imaging technique.

RESUMO

The prevalence and recurrence of whole-genome duplication in plants and its major role in evolution have been well recognized. Despite great efforts, many aspects of genome evolution, particularly the temporal progression of genomic responses to allopolyploidy and the underlying mechanisms, remain poorly understood. The rice genus Oryza consists of both recently formed and older allopolyploid species, representing an attractive system for studying the genome evolution after allopolyploidy. In this study, through screening BAC libraries and sequencing and annotating the targeted BAC clones, we generated orthologous genomic sequences surrounding the DEP1 locus, a major grain yield QTL in cultivated rice, from four Oryza polyploids of various ages and their likely diploid genome donors or close relatives. Based on sequenced DEP1 region and published data from three other genomic regions, we investigated the temporal evolutionary dynamics of four polyploid genomes at both genetic and expression levels. In the recently formed BBCC polyploid, O. minuta, genome dominance was not observed and its short-term responses to allopolyploidy are mainly manifested as a high proportion of homoeologous gene pairs showing unequal expression. This could partly be explained by parental legacy, rewiring of divergent regulatory networks and epigenetic modulation. Moreover, we detected an ongoing diploidization process in this genus and suggest that the expression divergence driven by changes of selective constraint probably plays a big role in the long-term diploidization. These findings add novel insights into our understanding of genome evolution after allopolyploidy and could facilitate crop improvements through hybridization and polyploidization.

RESUMO

The mechanism and influencing factors of an in-situ thermal remediation using electrical resistance heating were investigated. The effects of electrical current, heating method, rehydration, and negative pressure on soil heating and energy consumption were studied using in-situ electrical resistance heating equipment. The results showed that there were two main mechanisms for soil heating. Firstly, electric energy was converted into heat energy, whereby direct heating of the soil by electricity increased the soil temperature. This mechanism mainly existed in the soil between two electrodes. The second was heat conduction, whereby the soil temperature between the electrodes was the highest, and the heat gradually transferred from the high-temperature soil to the low-temperature soil, such that the temperature of the soil far away from the electrode connection gradually increased. The heating current affected the rate of increase of the soil temperature. The higher the current was, the faster the soil temperature rate of increase was and the lower the unit energy consumption was. Compared with continuous heating, intermittent heating had a slower heating rate and required a longer time to reach the same temperature. However, the energy consumption per unit was low and only 45.2% of that of continuous heating. During the heating process, water should be continuously added to the soil around the electrode to maintain a high current and continuous heating. The negative pressure of extraction was large, the soil heat loss was large, and the unit energy consumption was high. In actual projects, appropriate technological conditions should be selected according to time, cost, and the removal rate as a means of improving the efficiency of the in-situ resistance thermal desorption remediation of contaminated soil, reducing energy consumption, and shortening the time limit.

RESUMO

BACKGROUND: Smoking is prevalent among people in China. In this study, we examined the association between smoking and cognitive function in a representative sample of adults aged 45 years and older in China. METHODS: We analyzed the baseline data of 16,892 participants from the China Health and Retirement Longitudinal Study. We measured smoking based on smoking status (never, former, and current smokers) and pack years (one pack year equals 20 cigarettes per day for 1 year). We assessed cognitive function for visuospatial ability, episodic memory, orientation/attention, and overall cognitive function. Multivariate linear and logistic regressions were used to examine the independent association between smoking and cognitive function, controlling for sociodemographic factors, domestic partner status, physical health status, and depressive symptoms. RESULTS: The study participants were, on average, 60 years old. The prevalence of former and current smoking in this population was 8.4% and 28.8%, respectively. Compared with nonsmokers, former and current smokers had better cognitive function (p < .0001). After controlling for covariates, only former smokers, compared with nonsmokers, have better orientation and attention (p = .04) and overall cognitive function (p = .01). Moreover, pack years are positively associated with orientation, attention (p = .04), and overall cognitive function among all participants (p = .02). CONCLUSIONS: This study identified that, among middle-aged and older Chinese adults, former smokers had the highest cognitive function, especially attention and orientation, followed by never smokers and current smokers. When screening for cognition impairment among Chinese middle-aged and older adults, we should encourage them to quit smoking.

RESUMO

Pre-existing immune responses to seasonal endemic coronaviruses could have profound consequences for antibody responses to SARS-CoV-2, either induced in natural infection or through vaccination. Such consequences are well established in the influenza and flavivirus fields. A first step to establish whether pre-existing responses can impact SARS-CoV-2 infection is to understand the nature and extent of cross-reactivity in humans to coronaviruses. We compared serum antibody and memory B cell responses to coronavirus spike (S) proteins from pre-pandemic and SARS-CoV-2 convalescent donors using a series of binding and functional assays. We found weak evidence of pre-existing SARS-CoV-2 cross-reactive serum antibodies in pre-pandemic donors. However, we found stronger evidence of pre-existing cross-reactive memory B cells that were activated on SARS-CoV-2 infection. Monoclonal antibodies (mAbs) isolated from the donors showed varying degrees of cross-reactivity with betacoronaviruses, including SARS and endemic coronaviruses. None of the cross-reactive mAbs were neutralizing except for one that targeted the S2 subunit of the S protein. The results suggest that pre-existing immunity to endemic coronaviruses should be considered in evaluating antibody responses to SARS-CoV-2.

RESUMO

INTRODUCTION: This study aimed to evaluate the quality of home care in China using the Home Care Quality Assessment Tool (HCQuAT). METHOD: We recruited 38 home health agencies in Shanghai, China, which included 18 in urban areas, 11 in suburban areas, and nine in rural areas. Data on quality of home care from each agency were collected by trained staff using the HCQuAT. RESULTS: On average, these home health agencies scored 74.28/100.00 (SD = 6.80) on the HCQuAT, with an excellence rate of 39.5% and a failing rate of 23.7%. The mean scores on the structure quality module, process quality module, and outcome quality module were 71.2 ± 21.8, 86.6 ± 9.2, and 44.1 ± 37.5, respectively. Significant differences existed across geographic locations (p = .018). DISCUSSION: Significant variations were identified in the quality of home care across quality modules and geographic locations. Outcome quality and quality in rural areas were lower than those for their counterparts.

RESUMO

BACKGROUND: The relationship between poor oral health conditions and cognitive decline is unclear. OBJECTIVE: To examine the association between oral health and cognition in humans and rats. METHODS: In humans: a cross-sectional study was conducted. Cognitive levels were evaluated by the Mini Mental State Examination (MMSE); oral conditions were reflected by the number of missing index teeth, bleeding on probing, and probing pocket depth (PD). In rats: a ligature-induced (Lig) periodontitis model and Aß25-35-induced model of Alzheimer's disease (AD) were established; tumor necrosis factor-α (TNF-α), interleukin 1 (IL-1), interleukin 6 (IL-6), and C-reactive protein levels in the hippocampus and cerebral cortex were detected. RESULTS: MMSE scores for the number of missing index teeth ≥ 7 group were significantly lower than those in the ≤ 6 group. A negative relationship (correlation coefficient ρ = -0.310, P = 0.002) was observed between MMSE scores and number of missing index teeth. More missing index teeth and lower education levels were independent risk factors for cognitive decline. A negative relationship (correlation coefficient ρ = -0.214, P = 0.031) was observed between MMSE scores and average PD. TNF-α and IL-6 levels in the hippocampus of the Lig+AD group were significantly higher than those of the AD group. IL-1 and IL-6 levels in the cerebral cortex of the Lig+AD group were significantly higher than those of the AD group. CONCLUSION: Poor oral health conditions including more missing index teeth and higher average PD may be risk factors for cognitive decline. Periodontitis may increase inflammatory cytokines in rat models of AD.

RESUMO

BACKGROUND: Pain is common yet under-studied among older Medicare home health (HH) patients with Alzheimer's disease and related dementias (ADRD). AIMS: Examine (1) the association between ADRD and severe pain in Medicare HH patients; and (2) the impact of severe pain and ADRD on unplanned facility admissions in this population. DESIGN: Analysis of the Outcome and Assessment Information Set (OASIS) and Medicare claims data. SETTINGS/PARTICIPANTS: 6,153 patients ≥65 years receiving care from a nonprofit HH agency in 2017. METHODS: Study outcomes included presence of severe pain and time-to-event measures of unplanned facility admissions (hospital, nursing home, or rehabilitation facilities). ADRD was identified using ICD-10 diagnosis codes and cognitive impairment symptoms. Logistic regression and Cox proportional hazard models were used to examine, respectively, the association between ADRD and severe pain, and the independent and interaction effects of severe pain and ADRD on unplanned facility admission. RESULTS: Patients with ADRD (n = 1,525, 24.8%) were less likely to have recorded severe pain than others (16.4% vs. 23.6%, p < .001). Adjusting for demographics, comorbidities, mental and physical functional status, and use of HH services, having severe pain was related to a 35% increase (hazard ratio [HR] = 1.35, p = .002) in the risk of unplanned facility admission, but the increase in such risk was the same whether or not the patient had ADRD. CONCLUSIONS: HH patients with ADRD may have under-recognized pain. Severe pain is a significant independent predictor of unplanned facility admissions among HH patients.

RESUMO

BACKGROUND: Ningxia Hui Autonomous Region is an important cattle breeding area in China, and cattle breeding bases are located in this area. In Ningxia, dermatophytes have not been paid attention to, so dermatophytosis is becoming more and more serious. For effective control measures, it is important to determine the disease prevalence and isolate and identify the pathogenic microorganism. RESULTS: The study showed the prevalence of dermatophytes was 15.35% (74/482). The prevalence in calf was higher than adult cattle (p < 0.05). The morbidity was the highest in winter compared with autumn (p < 0.0001), summer (p < 0.05) and spring (p < 0.0001). The prevalence in Guyuan was the highest compared with Yinchuan (p < 0.05) and Shizuishan (p < 0.05). The incidence of lesions on the face, head, neck, trunk and whole body was 20.43, 38.71, 20.43, 10.75 and 9.68%, respectively. From all samples, the isolation rate of Trichophyton was highest (61.1%). The phylogenetic tree constructed showed that the 11 pathogenic fungi were on the same branch as Trichophyton verrucosum. CONCLUSIONS: This study reports, for the first time, the presence of Trichophyton verrucosum in cattle in Ningxia and showed that the incidence of dermatophytosis is related to different regions, ages and seasons. A better knowledge of the prevalence of dermatophytosis of cattle may allow the adoption of more efficient control measures and prophylaxis.

RESUMO

The development of countermeasures to prevent and treat COVID-19 is a global health priority. In under 7 weeks, we enrolled a cohort of SARS-CoV-2-recovered participants, developed neutralization assays to interrogate serum and monoclonal antibody responses, adapted our high throughput antibody isolation, production and characterization pipeline to rapidly screen over 1000 antigen-specific antibodies, and established an animal model to test protection. We report multiple highly potent neutralizing antibodies (nAbs) and show that passive transfer of a nAb provides protection against high-dose SARS-CoV-2 challenge in Syrian hamsters. The study suggests a role for nAbs in prophylaxis, and potentially therapy, of COVID-19. The nAbs define protective epitopes to guide vaccine design.

RESUMO

It is of critical importance for our understanding of speciation process to determine the forms of reproductive isolation and their relative importance in species divergence. Oryza nivara and O. rufipogon are direct ancestors of Asian cultivated rice and a progenitor-daughter species pair. Investigating the reproductive isolation between them provides insights into plant speciation and helps understanding of the rice domestication. Here, we quantitatively measured the major components of reproductive isolation between the two species based on common garden and crossing experiments for three pairs of sympatric populations in Nepal, Cambodia and Laos. We revealed significant differences in the flowering times between species pairs, with O. nivara flowering much earlier than O. rufipogon. A very weak reduction in seed set but no reduction in F1 viability and fertility were detected for the crosses between species relative to those within species. Moreover, we detected asymmetrical compatibility between species and found that emasculation significantly decreased pollination success in O. nivara but not in O. rufipogon. Our study demonstrates that the divergence between O. nivara and O. rufipogon is maintained almost entirely by the difference in flowering times and suggests that differential flowering times contribute to both habitat preferences and reproductive isolation between species.

RESUMO

Introduction: With the increasing need for home care in Shanghai, China, it is crucial to ensure its quality. This study aimed to explore quality-related issues of home care in Shanghai, China, and identify strategies for improvement. Method: This is a descriptive qualitative study. Semistructured interviews were conducted among 27 individuals, including home care managers (n = 8), nurses (n = 10), and patients and/or their caregivers (n = 9). Colaizzi's seven-step analysis method was used to guide data analysis. Results: Three themes emerged regarding the quality of home care in China: unsatisfactory structure quality, unsatisfactory process quality, and imperfect outcome quality evaluation system. Recommended strategies for quality improvement included issuing standards for home care evaluation, refining structure quality and process quality, and establishing an outcome quality evaluation system. Conclusions: Concerns about the quality of home care in China were identified by providers and patients. More research especially studies quantifying the care quality and its influencing factors are needed.

RESUMO

The purpose of this study was to synthesize research evidence from studies on the relationships among the BDNF Val66Met polymorphism, regular exercise, and cognition in human subjects. PubMed, CINAHL, and Web of Science were searched systematically. Search limiters applied in these databases included humans, English language, time limits from 2009 to 2019, and peer-reviewed journal articles. Eight studies were included in the current review. While there was some evidence to tentatively suggest that greater levels of exercise were associated with certain forms of memory in Val/Val homozygotes than Met carriers, more research is needed to corroborate these findings. Regarding attention/information processing speed, executive function as well as global cognition, the evidence is either inconsistent or sparse and does not allow for tentative conclusions. Compelling evidence from high-quality clinical trials is needed to re-examine the relationship between the BDNF Val66Met polymorphism, exercise, and cognition.

RESUMO

Although cognitive dysfunction is related to type 2 diabetes mellitus (T2DM), the concept has not yet been well defined. The purpose of this study was to define the concept of cognitive dysfunction in persons with T2DM and examine its defining attributes, antecedents, and consequences. Literature was retrieved from 2008 to 2018 by systematically searching the PubMed, CINAHL, and PsycINFO databases. Based on 37 included studies, three defining attributes were identified: cognitive dysfunction is a recognized or unrecognized symptom, is characterized by a subtle decline in one or more cognitive domains, and is accompanied by pronounced structural changes observed in brain imaging. One major antecedent was diabetes-related or diabetes-specific pathological changes. Consequences included interference with diabetes self-management, nonadherence to recommended self-management behaviors, and a higher risk of having hypoglycemic events. The concept analysis provides a theoretical foundation that can be used to guide evaluations and interventions related to cognitive dysfunction in individuals with T2DM.

RESUMO

This study aimed to identify symptom clusters of chronic obstructive pulmonary disease (COPD) and to examine the relationship between symptom clusters and health-related quality of life (HRQoL). It included 154 hospitalized patients with COPD. The majority of the participants (88.6%) were aged 60 years and above, and the numbers of men and women were approximately equal (men: 55.2%). The Charlson Comorbidity Index (CCI), the Memorial Symptom Assessment Scale (MSAS), and the Chinese version of the Clinical COPD Questionnaire (CCQ) were used to evaluate comorbidity, participant's symptoms, and HRQoL, respectively. Five symptom clusters were identified using exploratory factor analysis, and symptom clusters, especially the Psychological, Pain and Fatigue, GI, and Dyspnea-Sweat symptom clusters, had negative effects on HRQoL in patients with COPD. Understanding the patterns and occurrences of symptom clusters could be essential for developing effective interventions to manage COPD symptoms and improve the patients' HRQoL.

RESUMO

As Charles Darwin anticipated, living fossils provide excellent opportunities to study evolutionary questions related to extinction, competition, and adaptation. Ginkgo (Ginkgo biloba L.) is one of the oldest living plants and a fascinating example of how people have saved a species from extinction and assisted its resurgence. By resequencing 545 genomes of ginkgo trees sampled from 51 populations across the world, we identify three refugia in China and detect multiple cycles of population expansion and reduction along with glacial admixture between relict populations in the southwestern and southern refugia. We demonstrate multiple anthropogenic introductions of ginkgo from eastern China into different continents. Further analyses reveal bioclimatic variables that have affected the geographic distribution of ginkgo and the role of natural selection in ginkgo's adaptation and resilience. These investigations provide insights into the evolutionary history of ginkgo trees and valuable genomic resources for further addressing various questions involving living fossil species.
