Forebrain nuclei linked to woodpecker territorial drum displays mirror those that enable vocal learning in songbirds.

Vocal learning is thought to have evolved in 3 orders of birds (songbirds, parrots, and hummingbirds), with each showing similar brain regions that have comparable gene expression specializations relative to the surrounding forebrain motor circuitry. Here, we searched for signatures of these same gene expression specializations in previously uncharacterized brains of 7 assumed vocal non-learning bird lineages across the early branches of the avian family tree. Our findings using a conserved marker for the song system found little evidence of specializations in these taxa, except for woodpeckers. Instead, woodpeckers possessed forebrain regions that were anatomically similar to the pallial song nuclei of vocal learning birds. Field studies of free-living downy woodpeckers revealed that these brain nuclei showed increased expression of immediate early genes (IEGs) when males produce their iconic drum displays, the elaborate bill-hammering behavior that individuals use to compete for territories, much like birdsong. However, these specialized areas did not show increased IEG expression with vocalization or flight. We further confirmed that other woodpecker species contain these brain nuclei, suggesting that these brain regions are a common feature of the woodpecker brain. We therefore hypothesize that ancient forebrain nuclei for refined motor control may have given rise to not only the song control systems of vocal learning birds, but also the drumming system of woodpeckers.

Well-Performed Green Phosphor BaY4Si5O17:Ce3+,Tb3+ with High Quantum Efficiency and Thermal Stability.

For Tb3+-doped green phosphors, the energy transfer from Ce3+ to Tb3+ can largely enhance the absorption of excitation; however, obtaining phosphors that exhibit both high quantum efficiency and thermal stability continues to pose a significant challenge. Herein, we established a paradigm to achieve novel silicate BaY4Si5O17 (BYSO):Ce3+,Tb3+. The near-ultraviolet light efficiently excites the BYSO:Ce3+ material, causing it to emit light at a wavelength of 408 nm. The photoluminescence of BYSO:0.12Ce3+ exhibits a relatively small Stokes shift and a thermal stability of 89.8% of the 303 K emission intensity at 423 K (89.8%@423 K). The energy transfer (ET) from Ce3+ to Tb3+ ions can be readily constructed in BYSO:Ce3+,Tb3+ utilizing the overlap between the Ce3+ emission and the Tb3+ excitation. The ET efficiency from the Ce3+ to Tb3+ ions reached 83.8% at y = 1.2 and a maximum of 94.6%. Finally, the optimized phosphor BYSO:0.12Ce3+,1.2Tb3+ had an internal quantum efficiency of 94.4% and had excellent thermal stability (96.1%@423 K). Our work pointed out the avenue to novel green phosphors with high efficiency and thermal stability by choosing appropriate host and construct efficient ET.

The effect of neoadjuvant chemotherapy on surgical site wound infection after immediate breast reconstruction in patients with breast cancer: A meta-analysis.

Using a meta-analysis approach, we conducted a comprehensive evaluation of the effect of neoadjuvant chemotherapy (NACT) on the incidence of surgical site wound infection during immediate breast reconstruction (IBR) following breast cancer. The aim was to provide evidence-based support for the prevention of wound surgical site infection during IBR after breast cancer surgery. Relevant literature on the effects of NACT on IBR in patients with breast cancer published up until May 2023, was retrieved from various databases, including PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang databases, and China Biology Medicine Database. Two researchers performed the literature screening, data collection, and quality assessment of the included studies independently. The meta-analysis was conducted using Stata version 17.0. Fourteen studies involving 3401 patients (599 in the intervention group and 2802 in the control group) were included in the analysis. The incidence of surgical site infection in the NACT group was higher than that in the control group, but the difference between the two groups was not statistically significant (7.17% vs. 4.85%, odds ratio: 1.02, 95% confidence interval: 0.70-1.50, p = 0.902). These findings suggest that NACT does not increase the risk of surgical site infection during IBR. However, owing to the variation in sample size and literature quality among the included studies, randomised controlled trials are needed to confirm the safety of IBR in patients receiving neoadjuvant chemotherapy.

Triglyceride-glucose index predicts the risk of gestational diabetes mellitus: a systematic review and meta-analysis.

AIMS: We aimed to investigate the potential predictive efficacy of triglyceride-glucose (T/Gly) index for gestational diabetes mellitus (GDM) in a systematic review and meta-analysis. MATERIALS AND METHODS: Cohort studies demonstrating the association between T/Gly index measured at the first trimester or before pregnancy and the subsequent incidence of GDM were identified by search of PubMed, Embase, China National Knowledge Infrastructure, and WanFang databases. A random-effect model incorporating the heterogeneity was applied to pool the results. Five cohort studies including 382,213 women were included in this meta-analysis. RESULTS: Compared to those with the lowest category of T/Gly index, women with the highest category of T/Gly index were independently associated with higher risk of subsequent GDM (odds ratio [OR]: 2.52, 95% confidence interval [CI]: 1.33 ∼ 4.67, I2=65%, p=.004) after adjustment of potential confounding factors including age, body mass index, and family history of diabetes. The association was stronger in prospective cohort studies than retrospective cohort studies (p for subgroup difference=.007), and a significant association was detected in Asian women (OR: 3.30, 95% CI: 1.50-7.28, p =.003), but not in non-Asian women (OR: 0.96, 95% CI: 0.35-2.63, p=.94). CONCLUSIONS: Higher T/Gly index may independently predict the risk of GDM in Asian women.

Serum level of lipoprotein-associated phospholipase A2 is a potential biomarker of vertebrobasilar dolichoectasia and its progression to cerebral infarction.

BACKGROUND: There are no effective therapies to prevent the occurrence and progression of vertebrobasilar dolichoectasia (VBD). In this study, we investigated the relationship between serum levels of lipoprotein-associated phospholipase A2 (Lp-PLA2) and the occurrence and progression of VBD. METHODS: Sixty (60) cases without VBD and ischemia stroke were considered as Group A, 100 cases with VBD were further divided into Group B (VBD without ischemic stroke, n = 54) and Group C (VBD with first ever acute posterior circulation ischemic stroke, n = 46). Demographic data (such as gender and age) and past medical history (such as hypertension, diabetes, and smoking history) were collected. The levels of serum low-density lipoprotein cholesterol (LDL-C), hypersensitivity C reactive protein (hs-CRP), glycosylated hemoglobin (HbAlc), homocysteine (HCY), uric acid (UA), fibrinogen (Fib), and Lp-PLA2, etc. were measured. Logistic regression analysis was used to assess the related factors of VBD and ischemic stroke secondary to VBD. RESULTS: Logistic multivariate regression analysis showed that only age and the level of serum Lp-PLA2 were significantly higher in group B than those in group A (P < 0.012, P < 0.001, respectively), however, only the level of serum Lp-PLA2 was significantly higher in group C than those in group B (P < 0.001). CONCLUSIONS: The serum marker Lp-PLA2 is an independent risk factor for the occurrence of VBD and the progression of VBD to posterior circulation ischemic stroke. Whether intervening on atherosclerosis could prevent the occurrence and development of VBD needs to be further studied.

Severe Periodontitis Is Associated with Early-Onset Poststroke Depression Status.

BACKGROUND: Poststroke depression (PSD) is one of the most common complications after ischemic stroke, and periodontitis is associated with depression. However, whether severe periodontitis is associated with early-onset PSD status remains unknown. In this study, we aimed to investigate whether there is an association between severe periodontitis and PSD status in acute ischemic stroke patients. MATERIAL AND METHODS: We recruited 202 acute ischemic stroke patients within 7 days after stroke onset. Pocket depth and clinical attachment loss were assessed by oral examination to define the severe periodontitis. On the basis of diagnosis of PSD status according to DSM-5 criteria and a 24-item Hamilton Depression Rating Scale score greater than or equal to 8 within 2 weeks after stroke onset, we stratified patients into PSD status or non-PSD status groups and identified the independent predictors for the development of PSD status in multivariate logistic analysis. RESULTS: 77 (38.1%) patients were diagnosed as early-onset PSD status. PSD status group showed more severe periodontitis, lower income, lower Barthel Index (BI) score and Montreal Cognitive Assessment score, higher National Institutes of Health Stroke Scale score and modified Rankin scale (mRS) score compared with non-PSD status group. Multivariate logistic regression showed that severe periodontitis (odds ratio 2.401) and NIHSS score (>4, odds ratio 2.130) were independent predictors for early-onset PSD status. CONCLUSIONS: Severe periodontitis is found to be an important independent predictor of early-onset PSD status in patients with acute ischemic stroke, in addition to the well-known prognostic factors such as nonminor stroke assessed by NIHSS greater than 4.

Berberine Protects Secondary Injury in Mice with Traumatic Brain Injury Through Anti-oxidative and Anti-inflammatory Modulation.

Traumatic brain injury (TBI) is one of the major causes of death and disability worldwide. Novel and effective therapy is needed to prevent the secondary spread of damage beyond the initial injury. The aim of this study was to investigate whether berberine has a neuroprotective effect on secondary injury post-TBI, and to explore its potential mechanism in this protection. The mice were randomly divided into Sham-saline, TBI-saline and TBI-Berberine (50 mg/kg). TBI was induced by Feeney's weight-drop technique. Saline or berberine was administered via oral gavage starting 1 h post-TBI and continuously for 21 days. Motor coordination, spatial learning and memory were assessed using beam-walking test and Morris water maze test, respectively. Brain sections were processed for lesion volume assessment, and expression of neuronal nuclei (NeuN), cyclooxygenase 2 (COX-2), inducible nitric oxide synthase (iNOS), 8-hydroxy-2-deoxyguanosine (8-OHdG), ionized calcium-binding adapter molecule 1 (Iba1) and glial fibrillary acidic protein (GFAP) were detected via immunohistochemistry and immunofluorescence. There were statistically significant improvement in motor coordination, spatial learning and memory in the TBI-Berberine group, compared to the TBI-saline group. Treatment with berberine significantly reduced cortical lesion volume, neuronal loss, COX-2, iNOS and 8-OHdG expression in both the cortical lesion border zone (LBZ) and ipsilateral hippocampal CA1 region (CA1), compared to TBI-saline. Berberine treatment also significantly decreased Iba1- and GFAP-positive cell number in both the cortical LBZ and ipsilateral CA1, relative to saline controls. These results indicated that berberine exerted neuroprotective effects on secondary injury in mice with TBI probably through anti-oxidative and anti-inflammatory properties.

Rhythmic expressed clock regulates the transcription of proliferating cellular nuclear antigen in teleost retina.

Teleost fish continues to grow their eyes throughout life with the body size. In Astatotilapia burtoni, the fish retina increases by adding new retinal cells at the ciliary marginal zone (CMZ) and in the outer nuclear layer (ONL). Cell proliferation at both sites exhibits a daily rhythm in number of dividing cells. To understand how this diurnal rhythm of new cell production is controlled in retinal progenitor cells, we studied the transcription pattern of clock genes in retina, including clock1a, clock1b, bmal1a (brain and muscle ARNT-Like), and per1b (period1b). We found that these genes have a strong diurnal rhythmic transcription during light-dark cycles but not in constant darkness. An oscillation in pcna transcription was also observed during light-dark cycles, but again not in constant darkness. Our results also indicate an association between Clock proteins and the upstream region of pcna (proliferating cellular nuclear antigen) gene. A luciferase reporter assay conducted in an inducible clock knockdown cell line further demonstrated that the mutation on predicted E-Boxes in pcna promoter region significantly attenuated the transcriptional activation induced by Clock protein. These results suggested that the diurnal rhythmic expression of clock genes in A. burtoni retina could be light dependent and might contribute to the daily regulation of the proliferation of the retina progenitors through key components of cell cycle machinery, for instance, pcna.

NSF workshop report: discovering general principles of nervous system organization by comparing brain maps across species.

Efforts to understand nervous system structure and function have received new impetus from the federal Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative. Comparative analyses can contribute to this effort by leading to the discovery of general principles of neural circuit design, information processing, and gene-structure-function relationships that are not apparent from studies on single species. We here propose to extend the comparative approach to nervous system 'maps' comprising molecular, anatomical, and physiological data. This research will identify which neural features are likely to generalize across species, and which are unlikely to be broadly conserved. It will also suggest causal relationships between genes, development, adult anatomy, physiology, and, ultimately, behavior. These causal hypotheses can then be tested experimentally. Finally, insights from comparative research can inspire and guide technological development. To promote this research agenda, we recommend that teams of investigators coalesce around specific research questions and select a set of 'reference species' to anchor their comparative analyses. These reference species should be chosen not just for practical advantages, but also with regard for their phylogenetic position, behavioral repertoire, well-annotated genome, or other strategic reasons. We envision that the nervous systems of these reference species will be mapped in more detail than those of other species. The collected data may range from the molecular to the behavioral, depending on the research question. To integrate across levels of analysis and across species, standards for data collection, annotation, archiving, and distribution must be developed and respected. To that end, it will help to form networks or consortia of researchers and centers for science, technology, and education that focus on organized data collection, distribution, and training. These activities could be supported, at least in part, through existing mechanisms at NSF, NIH, and other agencies. It will also be important to develop new integrated software and database systems for cross-species data analyses. Multidisciplinary efforts to develop such analytical tools should be supported financially. Finally, training opportunities should be created to stimulate multidisciplinary, integrative research into brain structure, function, and evolution.

Pathological Complete Response with Neoadjuvant Trastuzumab, Pertuzumab, and Chemotherapy Followed by Modified Radical Mastectomy in a Patient with HER2-Positive Occult Breast Cancer.

BACKGROUND Occult breast cancer (OBC) is diagnosed when regional or distant metastases are found without evidence of a primary tumor. The low overall incidence is a great challenge for the management strategy of OBC. Aggressive diagnosis and personalized treatment are feasible treatment strategies for OBC. We report the case of an OBC patient who achieved pathological complete response (pCR) after neoadjuvant chemotherapy. CASE REPORT A 43-year-old woman was admitted to the hospital 6 months after detecting a lump in her left axilla, about the size of a quail egg, but not red or swollen, and the lump gradually grew. Mammography, ultrasound, and magnetic resonance imaging showed a visible left axilla lesion but no nodules in bilateral breasts. A core-needle biopsy of the axilla lesion revealed an invasive carcinoma of breast origin. The tumor cells were estrogen receptors (ER)-negative, progesterone receptor (PR)-negative, and HER2-positive (3+) by immunohistochemistry. The patient was finally diagnosed with HER2-positive, hormone receptor-negative occult breast cancer of the left breast, cT0N2M0, stage IIIA. The TCbHP regimen (docetaxel, carboplatin, trastuzumab, and pertuzumab) as neoadjuvant chemotherapy was given. She underwent a modified radical mastectomy, showing a pCR. Subsequent radiotherapy and HER2-targeted therapy were administrated. CONCLUSIONS This case highlights that even aggressive HER2-positive breast cancer can present as an occult primary tumor. Our clinical experience suggests that neoadjuvant chemotherapy followed by modified radical mastectomy can be effective for treating such rare cases. The patient achieved pCR, which can provide a therapeutic strategy for effective treatment of similar OBCs.

TYMS Knockdown Suppresses Cells Proliferation, Promotes Ferroptosis via Inhibits PI3K/Akt/mTOR Signaling Pathway Activation in Triple Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is characterized by a grim prognosis and numerous challenges. The objective of our study was to examine the role of thymidylate synthase (TYMS) in TNBC and its impact on ferroptosis. The expression of TYMS was analyzed in databases, along with its prognostic correlation. TYMS positive expression was identified through immunohistochemistry (IHC), while real-time quantitative PCR (qRTPCR) was employed to measure TYMS mRNA levels in various cell lines. Western blotting was utilized to assess protein expression. Cell proliferation, mobility, apoptosis, and reactive oxygen species (ROS) levels were evaluated using CCK8, wound scratch healing assay, transwell assay, and flow cytometry, respectively. Additionally, a tumor xenograft model was established in BALB/c nude mice for further investigation. Tumor volume and weight were measured, and histopathological analysis using hematoxylin and eosin (H&E) staining was conducted to assess tumor tissue changes. IHC staining was employed to detect the expression of Ki67 in tumor tissues. High expression of TYMS was observed in TNBC and was found to be correlated with poor prognosis in patients. Among various cell lines, TYMS expression was highest in BT549 cells. Knockdown of TYMS resulted in suppression of cell proliferation and mobility, as well as promotion of apoptosis. Furthermore, knockdown of TYMS led to increased accumulation of ROS and Fe2+ levels, along with upregulation of ACLS4 expression and downregulation of glutathione peroxidase 4 (GPX4) expression. In vivo studies showed that knockdown of TYMS inhibited tumor growth. Additionally, knockdown of TYMS was associated with inhibition of mTOR, p-PI3K, and p-Akt expression. Our research showed that the knockdown of TYMS suppressed the TNBC progression by inhibited cells proliferation via ferroptosis. Its underlying mechanism is related to the PI3K /Akt pathway. Our study provides a novel sight for the suppression effect of TYMS on TNBC.

Associations of apolipoprotein E ε4 allele, regional cerebral blood flow, and serum liver function markers in patients with cognitive impairment.

Introduction: The ε4 allele of the apolipoprotein E gene (APOE4) is expressed abundantly in both the brain and peripheral circulation as a genetic risk factor for Alzheimer's disease (AD). Cerebral blood flow (CBF) dysfunction is an essential feature of AD, and the liver plays an important role in the pathogenesis of dementia. However, the associations of APOE4 with CBF and liver function markers in patients with cognitive impairment remains unclear. We aimed to evaluate the associations of APOE4 with CBF measured by arterial spin labeling (ASL) magnetic resonance imaging (MRI) and serum liver function markers in participants who were diagnosed with cognitive impairment. Methods: Fourteen participants with AD and sixteen with amnestic mild cognitive impairment (MCI) were recruited. In addition to providing comprehensive clinical information, all patients underwent laboratory tests and MRI. All participants were divided into carriers and noncarriers of the ε4 allele, and T-tests and Mann-Whitney U tests were used to observe the differences between APOE4 carriers and noncarriers in CBF and liver function markers. Results: Regarding regional cerebral blood flow (rCBF), APOE4 carriers showed hyperperfusion in the bilateral occipital cortex, bilateral thalamus, and left precuneus and hypoperfusion in the right lateral temporal cortex when compared with noncarriers. Regarding serum liver function markers, bilirubin levels (including total, direct, and indirect) were lower in APOE4 carriers than in noncarriers. Conclusion: APOE4 exerts a strong effect on CBF dysfunction by inheritance, representing a risk factor for AD. APOE4 may be related to bilirubin metabolism, potentially providing specific neural targets for the diagnosis and treatment of AD.

Associations of Serum Liver Function with Cerebral Blood Flow in Patients with Alzheimer's Disease.

Background: Increasing evidence suggests that both amyloid-ß metabolism disorders in the liver and cerebral hypoperfusion play an important role in the pathogenesis of Alzheimer's disease (AD). However, the relevance of liver function alterations to cerebral blood flow (CBF) of patients with AD remains unclear. Objective: We aimed to investigate the associations between liver function changes and CBF of patients with AD. Methods: We recruited 17 patients with sporadic AD. In addition to physical and neurological examinations, detection of AD biomarkers in cerebrospinal fluid by enzyme-linked immunosorbent assay and CBF assessment by arterial spin labeling sequence of magnetic resonance image scans as well as measure of liver function markers in serum by routine laboratory testing were conducted. Neuropsychological tests were evaluated, including Mini-Mental State Examination and Montreal Cognitive Assessment. Linear and rank correlations were performed to test the associations of liver function alterations with regional CBF of AD. Results: We found that liver function markers, especially total protein, the ratio of albumin to globin, globin, alkaline phosphatase, and aspartate aminotransferase were significantly associated with regional CBF of AD patients. Conclusions: These findings demonstrated significant associations between perfusion in certain brain regions of AD and alterations of liver function markers, particularly proteins and liver enzymes, which might provide implications to the pathogenesis and treatment of AD.

Smart city community governance system based on online and offline aggregation services.

This paper takes smart city as an example, combining with online and offline aggregation services to explore the possible way out of county community governance innovation. In this white paper, community governance of online and offline aggregate services depends on the various assets and functions of the community, acts in collaboration with community stakeholders, and prevents and resists contingencies. Defined as a community with the ability to self-organize, self-adapt, and self-heal Interference or disaster to achieve sustainable development. This paper puts forward the benefit evaluation method of community governance, which is used to evaluate the implementation effect of online and offline community governance system. Taking a county as an example, this paper analyzes the impact of the challenge and novelty of this model on urban construction. Research shows that in the previous community governance model, about 50% of the people think that the managers of all institutions related to public welfare should not take management as the purpose, and even nearly 70% of the respondents also stressed that these institutions should not be allowed to collect legal management fees or commission fees. At the same time, 40% of respondents admitted that they did not trust the quality of free services provided by public welfare agencies. The online and offline aggregate service modes adopted by the city not only work well in the city's economy, but also increase the city's GDP by 12%. This is 3.6% higher than in the previous mode. In addition, this model will accelerate the process of democratic construction and improve people's happiness index.

VIRMA Facilitates Triple-Negative Breast Cancer Progression via Increasing m6A-Dependent KIF15 Expression.

BACKGROUND: Vir like N6-methyladenosine (m6A) methyltransferase associated protein (VIRMA) is associated with various tumors, but the specific role of VIRMA in triple-negative breast cancer (TNBC) and the mechanisms are still unclear. Thus, in this study, in addition to the effect of VIRMA on TNBC, the underlying mechanisms were also explored. METHODS: In vitro, VIRMA expression was detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot; VIRMA lentiviral overexpression vector (LV-VIRMA) and lentiviral vector connected with the shRNA targeting VIRMA (LV-shVIRMA) were constructed to explore the functional role of VIRMA; RNA immunoprecipitation and qRT-PCR were performed to assess the relationship between VIRMA and kinesin family 15 (KIF15). In vivo, female Balb/C mice (n = 6) were subcutaneously injected with TNBC cells transfected with LV-shRNA + LV-NC (negative control), LV-shVIRMA + LV-NC, and LV-shVIRMA + LV-KIF15, tumor volume, weight and immunohistochemistry staining of Ki-67 were employed to assess breast tumor growth; immunohistochemistry of VIRMA and KIF15 were performed to examine VIRMA and KIF15 expression in breast tumor tissues. RESULTS: Compared to normal breast epithelial cells, VIRMA was increased in TNBC cells (p < 0.01 and p < 0.001). LV-VIRMA elevated proliferation, metastasis and invasion of TNBC cells in comparison with LV-NC (p < 0.001), while VIRMA knockdown resulted in the opposite effects in comparison with LV-shRNA NC (p < 0.01 and p < 0.001). Also, compared to LV-shRNA NC, LV-shVIRMA downregulated KIF15 expression by reducing KIF15 mRNA stability (p < 0.05 and p < 0.001), which was dependent on m6A. Furthermore, compared to LV-shVIRMA + LV-NC, LV-shVIRMA + LV-KIF15 not only reversed the reduced proliferation, metastasis and invasion of TNBC cells (p < 0.05, p < 0.01, and p < 0.001), but also reversed the decreased tumor weight and volume (p < 0.05, p < 0.01, and p < 0.001). CONCLUSIONS: The above results indicated that VIRMA promoted TNBC progression by upregulating m6A-dependent KIF15 expression, providing a better understanding of the pathogenesis of TNBC.

Public sense of dental implants on social media: A cross-sectional study based on text analysis of comments.

OBJECTIVES: To investigate the most discussed topics and possible new interests in dental implants among the public, as well as the public sentiments toward dental implants through topic and sentiment analysis of online comments. METHODS: Comments of the top 100 most viewed dental implant-related YouTube videos were studied. The comments were analyzed by topic analysis (LDA topic model, Word co-occurrence analysis) and sentiment analysis. The basic information of videos was collected and classified. Video quality was evaluated by GQS criteria and 9-point usefulness scoring system. Statistical analyses were performed using Kruskal-Wallis test, Mann-Whitney U-tests, and Spearman correlation analysis. RESULTS: 74 videos with 61,618 comments were considered eligible in this study. Most videos targeted the public with high viewing and comments, but the theme was single and the quality was low. From topic analysis, the most discussed topics in the comments were procedure, cost, feelings associated with prognosis, and expectations. Multidisciplinary approaches in implant dentistry were frequently discussed. From sentiment analysis, the public mainly expressed positive sentiment through comments. In detail, the public had positive feelings about aesthetics and health, negative feelings about pain, and neutral feelings about cost. CONCLUSION: The hot topics of public concern were procedure, cost, feelings associated with prognosis, and expectations. Intriguingly, multidisciplinary approaches in implant dentistry have emerged as a new hot subtopic within the topic "procedure". Based on the sentiment analysis of the comments, the general sentiment expressed by the public toward dental implants was predominantly positive. CLINICAL SIGNIFICANCE: Text mining can extract data from social media to explore public interest in dentistry. Clinicians should convey reasonable expectations and understanding about dental implants, especially addressing the most public-concerned topics (procedure, cost, feelings, and expectations), and provide patients with well-grounded multidisciplinary treatment plans to meet the growing public demand.

LncRNA MIR31HG promotes cell proliferation and invasive properties of the MCF-7 cell line by regulation of receptor-interacting serine-threonine kinase 4.

LncRNA MIR31HG is involved in many types of cancers, while its roles in breast cancer are still unknown. The current study aimed to explore the function of lncRNA MIR31HG in breast cancer and the underlying mechanisms. Stable expression cell lines were constructed by using lentivirus particles. MTT assay was used to determine cell viability. Wound healing and Transwell assay were used to determine cell migration and invasion, respectively. The changes in biomarkers were determined by using qPR-PCT and Western blotting, respectively. BALB/c nude mice were used to generate a xenograft mouse model. MIR31HG regulated cell proliferation, migration and invasion in MCF7 cells. Besides, MIR31HG regulated N-Cadherin, Vimentin, and E-Cadherin. MIR31HG positively regulated receptor-interacting serine-threonine kinase 4 (RIPK4), as supported by the fact that knockdown of MIR31HG suppressed RIPK4, and the knockdown of RIPK4 did not affect MIR31HG. Additionally, we found that RIPK4 regulated cell proliferation, migration and invasion in MCF7 cells. The changes in RIPK4 regulated N-Cadherin, Vimentin, and E-Cadherin. Consistently, in vivo studies showed that the knockdown of MIR31HG or RIPK4 reduced tumor size in xenograft animal models. The roles of lncRNA MIR31HG in breast cancer were associated with its regulatory effects against RIPK4.

Predicting the Factors of Employee Agility Using Enterprise Social Media: The Moderating Role of Innovation Culture.

This study aims to create a research model that examines how employee agility is affected by enterprise social media usage (ESMU), and to discuss the moderating role of innovation culture in communication quality, trust, and employee agility using the relational capital theory. Data of 477 Chinese employees from different companies were collected in this study for analysis, and the hypotheses developed were examined. The purpose of this study was to explore the influence mechanism that propels employees' ESMU, communication quality and trust and the moderating effect of innovation culture. This study conducts PLS-SEM to analyze collected data. The results show that ESMU is positively associated with communication quality and trust; innovation culture plays a positive moderating role in ESMU and employee agility; and high communication quality and trust can lead to high agility. However, innovation culture does not have a remarkable moderating effect on ESMU and communication quality. This study offers empirical evidence on how the effect of ESMU on employee agility is transferred by innovation culture. In addition, the benefits of enterprise social media for organizational management are also measured in this study, which may motivate the managements to introduce enterprise social media in work spaces.

Effects of Physical Exercise on Mobile Phone Addiction in College Students: The Chain Mediation Effect of Psychological Resilience and Perceived Stress.

Smartphones have become an integral part of people's daily lives. While bringing convenience, mobile phone addiction caused by overuse of smart phones has become a common phenomenon among college students. The current study aimed to examine the serial mediating role of psychological resilience and perceived stress between physical exercise and mobile phone addiction of college students. Using the PARS-3 scale, CD-RISC-10 scale, PSS-10 scale, and MPA scale, 257 college students were investigated and Structural Equation Model (SEM) was conducted. The results show that: (1) Physical exercise has no significant direct impact on mobile phone addiction. (2) Psychological resilience has a significant mediating effect between physical exercise and mobile phone addiction. But perceived stress does not. (3) Psychological resilience and perceived stress play a chain mediation role. Physical exercise can enhance psychological resilience firstly, thus relieving perceived stress and eventually mitigating mobile phone addiction.
