GLUT1 promotes cell proliferation via binds and stabilizes phosphorylated EGFR in lung adenocarcinoma.

BACKGROUND: While previous studies have primarily focused on Glucose transporter type 1 (GLUT1) related glucose metabolism signaling, we aim to discover if GLUT1 promotes tumor progression through a non-metabolic pathway. METHODS: The RNA-seq and microarray data were comprehensively analyzed to evaluate the significance of GLUT1 expression in lung adenocarcinoma (LUAD). The cell proliferation, colony formation, invasion, and migration were used to test GLUT1 's oncogenic function. Co-immunoprecipitation and mass spectrum (MS) were used to uncover potential GLUT1 interacting proteins. RNA-seq, DIA-MS, western blot, and qRT-PCR to probe the change of gene and cell signaling pathways. RESULTS: We found that GLUT1 is highly expressed in LUAD, and higher expression is related to poor patient survival. GLUT1 knockdown caused a decrease in cell proliferation, colony formation, migration, invasion, and induced apoptosis in LUAD cells. Mechanistically, GLUT1 directly interacted with phosphor-epidermal growth factor receptor (p-EGFR) and prevented EGFR protein degradation via ubiquitin-mediated proteolysis. The GLUT1 inhibitor WZB117 can increase the sensitivity of LUAD cells to EGFR-tyrosine kinase inhibitors (TKIs) Gefitinib. CONCLUSIONS: GLUT1 expression is higher in LUAD and plays an oncogenic role in lung cancer progression. Combining GLUT1 inhibitors and EGFR-TKIs could be a potential therapeutic option for LUAD treatment.

Symptoms of post traumatic stress disorder and their relationship with the fear of COVID-19 and COVID-19 burden among health care workers after the full liberalization of COVID-19 prevention and control policy in China: a cross-sectional study.

BACKGROUND: Over the past three years, the COVID-19 pandemic has brought an overwhelming impact on China's hospital system and health care workers, which can lead to post traumatic stress disorder (PTSD) symptoms. Previous research has shown that the COVID-19 pandemic had long-term adverse effects on the mental health of health care workers. Indeed, PTSD symptoms have emerged as one of the significant mental health issues for health care workers arising from the COVID-19 pandemic. Therefore, we conducted this cross-sectional survey to investigate the prevalence of PTSD symptoms in health care workers and its relationship with the fear of COVID-19 and the COVID-19 burden after the full liberalization of COVID-19 prevention and control policy in China. METHODS: This study was conducted three years after the global COVID-19 pandemic (January 15 to January 16, 2023). This study was conducted via the Wenjuanxing platform and used the Chinese versions of the scales PC-PTSD-5, COVID-19 Anxiety Scale (FCV-19S), Social Support Scale, COVID-19 Stress Scale, GAD-2, and PHQ-2. RESULTS: The prevalence of PTSD symptoms in health care workers was 24.3% (232/955). depression(P < 0.001), anxiety(P < 0.05), the fear of COVID-19(P < 0.001), and COVID-19 burden(P < 0.001) were highly correlated with PTSD symptoms in health care workers. Social support(P < 0.05) was a protective factor of PTSD symptoms. CONCLUSIONS: This survey shows that PTSD symptoms were highly prevalent among Chinese health care workers after the COVID-19 pandemic. Governments and leaders of medical institutions should, through psychological interventions, address the current situation of PTSD symptoms among health care workers and develop targeted programs and strategies to reduce their psychological problems.

Clinical Research Progress of the Post-Stroke Upper Limb Motor Function Improvement via Transcutaneous Auricular Vagus Nerve Stimulation.

Stroke is a disease with high morbidity and disability, and motor impairment is a common sequela of stroke. Transcutaneous auricular vagus nerve stimulation (taVNS) is a type of non-invasive stimulation, which can effectively improve post-stroke motor dysfunction. This review discusses stimulation parameters, intervention timing, and the development of innovative devices for taVNS. We further summarize the application of taVNS in improving post-stroke upper limb motor function to further promote the clinical research and application of taVNS in the rehabilitation of post-stroke upper limb motor dysfunction.

Smartphone addiction and its associated factors among freshmen medical students in China: a cross-sectional study.

BACKGROUND: With smartphone use widespread worldwide, smartphone addiction is an emerging epidemic. This study aims to investigate the prevalence of smartphone addiction among freshmen medical students and to explore its association with personal factors, mental health, and professional identity. METHODS: This cross-sectional study was conducted from October 10th to November 10th, 2020 and included 2,182 first-year college students at Wannan Medical College, China. The smartphone addiction test, professional identity, and a 12-item general health questionnaire were used for this cross-sectional survey. Pearson's correlation coefficient (r) was employed to examine the correlations between smartphone addiction and mental health and professional identity. Binary logistic regression analysis was carried out to assess the factors influencing smartphone addiction. Of the 2,182 students, 866 (39.7%) were identified as having smartphone addiction. The logistic regression analysis shows that four factors (professional identity scale, poor mental health, smartphone use before sleep, and perceived study pressure) were significantly associated with smartphone addiction. CONCLUSIONS: This cross-sectional study suggests that smartphone addiction is common among Chinese freshmen medical students. Smartphone addiction was common among the freshmen medical students surveyed. The findings imply that promotional programs, aimed at enhancing mental health and professional identity among freshmen medical students, help to reduce smartphone addiction in this population.

Prevalence of smartphone addiction and its effects on subhealth and insomnia: a cross-sectional study among medical students.

OBJECTIVE: This study aimed to assess Chinese medical students' smartphone addiction and its effects on subhealth and insomnia. METHODS: A cross-sectional survey was conducted from October 14, 2020 to November 14, 2020 by administering an online questionnaire to Wannan Medical College students. RESULTS: Of 2741 students who completed the survey, 1,447 (52.8%) had smartphone addiction. Medical specialty (p = 0.004), alcohol consumption (p = 0.001), smartphone use in bed (p = 0.000), depression (p = 0.000) and anxiety (p = 0.000) were strongly associated with smartphone addiction. The impacts of smartphone addiction on subhealth (p = 0.000) and insomnia (p = 0.000) were significant. CONCLUSION: This survey shows that the smartphone addiction detection rate among medical students was 52.8%. Students who did not like their medical specialty, consumed alcohol, used their smartphones in bed, and suffered from depression and anxiety had a higher smartphone addiction detection rate. The subhealth and insomnia of medical students are adversely associated with smartphone addiction.

Dietary shifts and diversities of individual life histories reveal cultural dynamics and interplay of millets and rice in the Chengdu Plain, China during the Late Neolithic (2500-2000 cal. BC).

OBJECTIVES: We undertook a more comprehensive analyses than our previous study (Yi et al., International Journal of Osteoarchaeology, 2018, 28, 636-644) at the Gaoshan site (~2500-2000 cal. BC) to expand our understanding of the different roles of rice and millets to human subsistence strategies, diachronic shift of human diets, diversity of human life histories and cultural influence (dental ablation) to human population. MATERIALS AND METHODS: Carbon and nitrogen isotopic analyses of human (ribs and long bones, n = 68) and animal (n = 15) bones as well as carbonized seeds from rice and millets (n = 8) were undertaken. Human bones were directly AMS-14 C dated. In addition, sequential sampling of 16 individuals with varied age and sex and cultural contexts for isotopic analysis was also conducted. RESULTS: The calibrated dating results (n = 27) indicate that there existed two periods of occupation at the site, ~2500-2200 BC and ~2200-1900 BC. Moderate high δ15 N values were found in the crops. Isotopic data from bone collagen suggest that the humans mainly relied on C3 -based animal protein and were supplemented by C4 -based foods. This isotopic pattern is also seen in pigs. Significant difference of human δ13 C values (Mann-Whitney U test, p < 0.05) between the two periods was observed. Compared to the bones, the isotopic data of human dentine serial sections show a much wider variability and higher δ13 C values. DISCUSSION: The crops (millets and rice) were probably manured. Human individuals subsisted on rice/millet agriculture and pigs in general. In combination with the radiocarbon dates, the increase of C3 (rice) consumption by the humans was found from the early (2500-2200 cal. BC) to late (2200-2000 cal. BC) periods, indicating the intensification of rice agriculture through time. However, four categories of human life histories during childhood are identified given different isotopic profiles of dentine sections, demonstrating that C3 (rice) and C4 (millets)-based foods played different roles in human lives. Even though, there were similar weaning practices among the human populations. It is surprising that human individuals with dental ablation, cultural characteristic in the Middle and Lower Yangtze River Valley, consumed more millets during childhood in the early period than those without dental ablation in the late period. Our study here provides novel insights into cultural dynamics and the interplay between rice and millets in rice-millet agricultural system during the Late Neolithic in Southwest China.

Predictors and consequences of visual trajectories in Chinese older population: A growth mixture model.

Background: Given the relatively high prevalence of vision impairment and the heterogeneity of visual changes among the elderly population, we aimed to identify the visual trajectories and to examine the predictors and consequences associated with each trajectory class. Methods: We analysed data from 2235 participants involved in the 5th, 6th, 7th, and 8th waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), where vision impairment was evaluated using an adapted Landolt-C chart during each wave. We employed a growth mixture model (GMM) to identify distinct visual trajectories and logistic regression analysis to examine the predictors associated with each trajectory class. Furthermore, we investigated the effect of visual trajectories on distal consequences, including cognitive function, activities of daily living (ADL), instrumental activities of daily living (IADL), depression, anxiety, and fall risk. Within the CLHLS study, cognitive function was assessed using the Chinese version of the Mini-Mental State Examination (CMMSE), ADL via the Katz index, and IADL through a modified version of Lawton's scale. Lastly, depression was assessed using the 10-item version of the Centre for Epidemiologic Studies (CES-D-10), while anxiety was measured using the Generalized Anxiety Disorder scale (GAD-7). Fall risk was determined by asking the question: 'Have you experienced any falls within the past year?' Results: We identified two distinct visual trajectories in our analysis. Most older adults (n = 1830, 81.9%) initially had a good vision level that diminished ('high-baseline decline' group). Conversely, the remaining participants (n = 405, 18.1%) initially had a lower vision level that improved over time ('low-baseline improvement' group). The 'high-baseline decline' group was more likely to include older adults with relatively higher body mass index (BMI) (odds ratio (OR) = 1.086; 95% confidence interval (CI) = 1.046, 1.127), individuals with higher formal educational qualifications (OR = 1.411; 95% CI = 1.068, 1.864), those current engaging in exercise (OR = 1.376; 95% CI = 1.046, 1.811), and individuals reporting more frequent consumption of fruit (OR = 1.357; 95% CI = 1.053, 1.749). Conversely, the 'low-baseline improvement' group had a higher likelihood of including older individuals (OR = 0.947; 95% CI = 0.934, 0.961), residents of nursing homes (OR = 0.340; 95% CI = 0.116, 0.993) and those self-reporting cataracts (OR = 0.268; 95% CI = 0.183, 0.391) and glaucoma (OR = 0.157; 95% CI = 0.079, 0.315). Furthermore, the 'high-baseline decline' group showed a positive impact on distal consequences, adjusting for sex, birthplace, residence, main occupation, education, economic status, and marital status. This impact included cognitive function (correlation coefficient (ß) = 2.092; 95% CI = 1.272, 2.912), ADL (ß = -0.362; 95% CI = -0.615, -0.108), IADL (ß = -1.712; 95% CI = -2.304, -1.121), and reported lower levels of depression (ß = 0.649; 95% CI = 0.013, 1.285). We observed no significant influence on fall risk and anxiety within the identified visual trajectories in the adjusted model. Conclusions: Vision in older adults with ocular disease could potentially be improved. Having formal education, maintaining an appropriate BMI, engaging in exercise, and consuming fruit more frequently appear to be beneficial for the visual health of the elderly. Considering the negative impact of visual impairment experience on distal cognition, self-care ability, and depression symptoms, stakeholder should prioritise long-term monitoring and management of vision impairment among older adults.

Family-to-work conflict and instigated incivility: The role of negative affect and family supportive supervisor behaviours.

While prior research has extensively explored outcomes of family to-work conflict (FWC), our understanding of how FWC may impact employees' negative interpersonal behaviours at work such as workplace incivility is limited. Given the serious implications of workplace incivility, the current study seeks to understand the relationship between FWC and instigated incivility via the mediating role of negative affect. The moderating role of family supportive supervisor behaviours (FSSB) is also investigated. We collected data from 129 full-time employees over three waves with six weeks in between. Results revealed that FWC positively predicted instigated incivility, and negative affect mediated this relationship. In addition, the positive effect of FWC on negative affect as well as the indirect effect of FWC on instigated incivility through negative affect were weaker for individuals experiencing more FSSB, suggesting that family related support from supervisors may attenuate the effect of FWC on employees' negative affect and its indirect effect on instigated incivility via negative affect. Theoretical and practical implications are also discussed.

Dietary Dihydromyricetin Zinc Chelate Supplementation Improves the Intestinal Health of Magang Geese.

To fulfill the nutritional requirements of poultry, effective Zn supplementation is required due to Zn deficiency in basic feed. In this study, we investigated the effects of DMY-Zn (dihydromyricetin zinc chelate) on the growth performance, morphology, and biochemical indices; the expression of intestinal barrier-related genes; the intestinal microflora; and the cecum metabolome of Magang geese. A total of 300 14-day-old Magang geese (equal number of males and females) with an average body weight of 0.82 ± 0.08 kg were randomly divided into five groups and fed a basal diet; these groups were given DMY-Zn (low, medium, or high level of DMY-Zn with 30, 55, or 80 mg/kg Zn added to the basal diet) or ZnSO4 (80 mg/kg Zn added) for 4 weeks. Our results revealed that DMY-Zn significantly impacts growth and biochemical indices and plays a significant role in regulating the intestinal barrier and microflora. DMY-Zn is involved in the upregulation of intestinal barrier gene (ZO1 and MUC2) expression, as well as upregulated Zn-related gene expression (ZIP5). On the other hand, a low concentration of DMY-Zn increased the ɑ diversity index and the abundance of Lactobacillus and Faecalibacterium. Additionally, a cecal metabolomics study showed that the main metabolic pathways affected by DMY-Zn were the pentose phosphate pathway, the biosynthesis of different alkaloids, and the metabolism of sphingolipids. In conclusion, DMY-Zn can reduce feed intake, increase the expression of intestinal barrier-related genes, help maintain the intestinal microflora balance, and increase the abundance of beneficial bacteria in the intestine to improve intestinal immunity.

Prevalence and associated factors of insomnia symptoms after ending China's dynamic zero-COVID policy: a cross-sectional survey of frontline nursing staff in Chinese hospitals.

Background: After the Chinese government announced the end of the dynamic zero-COVID policy on January 8, 2023, the COVID-19 pandemic peaked. Frontline nursing staff are at high risk of infection transmission due to their frequent contact with COVID-19 patients. In addition, due to the ending of China's dynamic zero-COVID policy, frontline nursing staff have grappled with increased workload, fatigue, and more. This study aimed to explore the prevalence of insomnia symptoms in frontline nursing staff and its influencing factors following the end of the policy. Methods: Between January and February 2023, this study was conducted by the Wenjuanxing platform to survey frontline nursing staff in a hospital in Wuhu City, Anhui Province. All the nursing staff included in this study had a COVID-19 infection. The questionnaires included the Athens Insomnia Scale (AIS), PC-PTSD-5 Chinese Version Scale, the Fear of COVID-19 Scale, The 2-item Connor-Davidson Resilience Scale (CD-RISC-2) Scale, and the burden of COVID-19 Scale. Binary logistic regression methods were used to identify variables associated with insomnia symptoms. Results: Among the 694 frontline nursing staff, 74.5% (517/694) exhibited insomnia symptoms. Fear of COVID-19 (p < 0.001), the burden of COVID-19 (p < 0.05), PTSD (p < 0.001), and higher technical titles (p < 0.008) were highly correlated with insomnia symptoms in frontline nursing staff. Psychological resilience (p < 0.001) was a protective factor for insomnia symptoms among frontline nursing staff. Conclusion: After ending China's dynamic zero-COVID policy, the prevalence of insomnia symptoms among frontline nursing staff is generally higher. This study highlights the association between insomnia symptoms and PTSD, fear of COVID-19, COVID-19 burden, and resilience. Psychological assistance is needed for frontline nursing staff to prevent insomnia symptoms and protect the mental health of frontline nursing staff after the end of China's dynamic zero-COVID policy.

Disparities in sleep duration and quality by industry of employment and occupational class among Native Hawaiian/Pacific Islanders and non-Hispanic Whites in the United States.

OBJECTIVE: To investigate disparities in the work-sleep relationship between Native Hawaiian/Pacific Islanders (NHPIs) and non-Hispanic (NH)-White populations. METHODS: Using data from a nationally representative sample of U.S. adults (n = 20,828) in the 2014 National Health Interview Survey, we estimated prevalence of short sleep duration (<7 hours) among NHPIs (10%) and NH-Whites for each of 7 employment industry categories and 3 occupational classes. Mean age was 41 ± 0.5years for NHPIs and 49 ± 0.2years for NH-Whites. Women comprised 52% of both groups. RESULTS: NHPIs were more likely than NH-Whites to report short sleep duration across all industry of employment categories (except for food and accommodation services) and occupational classes. The disparity was widest among NHPI and NH-White workers in the "professional/management" industry category, with NHPIs having higher prevalence of very short (<6 hours; 20% vs. 7%) and short sleep (30% vs. 22%) durations and lower prevalence of recommended sleep duration (45% vs. 68%) and waking up feeling rested (53% vs. 67%). Among the occupational classes, the NHPI-White disparity was widest among participants who held support service occupations. Although professionals had the lowest and laborers had the highest prevalence of short sleep among the three occupational classes in both NHPI and NH-White groups, short sleep duration prevalence was higher among NHPI professionals (35%) than NH-White laborers (33%). NH-White workers across industry and occupational classes had higher sleep medication use prevalence compared to NHPI workers. CONCLUSIONS: The work environment via occupation type may contribute to racial/ethnic disparities in short sleep. Further investigations are warranted.

Growth Performance of and Liver Function in Heat-Stressed Magang Geese Fed the Antioxidant Zinc Ascorbate and Its Potential Mechanism of Action.

The aim of this study was to investigate the in vitro antioxidant activity of zinc ascorbate (AsA-Zn), its effects on the growth performance of and liver function in Magang geese under heat stress, and its potential mechanism. At AsA-Zn concentrations of 7.5, 15, 30, and 60 µmol/L, the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS·+) radical scavenging rate increased significantly by 120.85%, 53.43%, 36.12%, and 0.99%, respectively, compared with that of ascorbic acid (AsA), indicating that AsA-Zn had better antioxidant performance in vitro. In this study, Magang geese were divided into a control group (basal diet, CON) and experimental groups, who received the basal diet supplemented with 400 mg/kg AsA or 30 (AsA-Zn30), 60 (AsA-Zn60), or 90 (AsA-Zn90) mg/kg AsA-Zn. AsA-Zn supplementation considerably reduced the feed-to-gain ratio, whereas both AsA and AsA-Zn significantly increased the thymus index. Moreover, AsA-Zn supplementation improved serum protein levels, lipid metabolism, liver function, and antioxidant capacity while reducing hepatocyte vacuolar degeneration. Furthermore, supplementation with AsA-Zn60 significantly increased the total antioxidant capacity, glutathione peroxidase activity, and superoxide dismutase activity and decreased the malondialdehyde content in the serum, liver, and hepatic mitochondria (P < 0.05), with more pronounced effects in the AsA-Zn60 group. Moreover, supplementation with ASA-Zn regulated the Nrf 2 signaling pathway and significantly increased the expression of genes encoding antioxidant-related factors in the liver. In conclusion, AsA-Zn has good antioxidant activity, and AsA-Zn supplementation may improve the antioxidant capacity of heat-stressed geese and promote their growth. Supplementation with 30 mg/kg AsA-Zn is recommended.

Prevalence and Associated Factors of Depression Among Frontline Nurses in Wuhan 6 Months After the Outbreak of COVID-19: A Cross-Sectional Study.

BACKGROUND Due to the COVID-19 pandemic, frontline nurses have experienced psychological problems. However, the depression of frontline nurses in Wuhan 6 months after the outbreak of COVID-19 has not been studied adequately. The purpose of this study was to investigate the depression of frontline nurses in Wuhan 6 months after the COVID-19 outbreak and to analyze possible risk and protective factors. MATERIAL AND METHODS Data were collected through Wenjuanxing from 612 frontline nurses in Wuhan national COVID-19-designated hospitals between July 27, 2020, and August 12, 2020. The levels of depression, family functioning, and psychological resilience were assessed among frontline nurses in Wuhan with a depression scale, family function scale, and 10-item psychological resilience scale, respectively. The factors associated with depressive symptoms were identified using the chi-square test and binary logistic regression analysis. RESULTS A total of 126 respondents were included in the study. The overall prevalence of depression was 25.2%. The need for mental health services was a potential risk factor for depressive symptoms, while family functioning and psychological resilience were potential protective factors. The COVID-19 pandemic poses a major challenge to the depressive symptoms of frontline nursing in Wuhan, highlighting the need for all frontline nurses in Wuhan to be screened for depression regularly for timely intervention. CONCLUSIONS To mitigate the impact of the pandemic on depression, psychological interventions for frontline nurses need to be implemented to preserve their mental health.

Application of single-cell sequencing to the research of tumor microenvironment.

Single-cell sequencing is a technique for detecting and analyzing genomes, transcriptomes, and epigenomes at the single-cell level, which can detect cellular heterogeneity lost in conventional sequencing hybrid samples, and it has revolutionized our understanding of the genetic heterogeneity and complexity of tumor progression. Moreover, the tumor microenvironment (TME) plays a crucial role in the formation, development and response to treatment of tumors. The application of single-cell sequencing has ushered in a new age for the TME analysis, revealing not only the blueprint of the pan-cancer immune microenvironment, but also the heterogeneity and differentiation routes of immune cells, as well as predicting tumor prognosis. Thus, the combination of single-cell sequencing and the TME analysis provides a unique opportunity to unravel the molecular mechanisms underlying tumor development and progression. In this review, we summarize the recent advances in single-cell sequencing and the TME analysis, highlighting their potential applications in cancer research and clinical translation.

Effects of two-dimensional cyber incivility on employee well-being from a self-determination perspective.

The research attempts to explore the effects of two-dimensional cyber incivility on employee well-being. Based on self-determination theory and regulatory focus theory, we conducted two studies to examine the mediating role of intrinsic motivation and the moderating role of promotion focus between cyber incivility and emotional exhaustion. The results demonstrated that both active and passive cyber incivility predicted increased emotional exhaustion, with intrinsic motivation serving as a key mediator. There was no consistent conclusion of promotion focus's moderating role. High promotion focus might aggravate the negative effect of passive cyber incivility on intrinsic motivation. The present article provides deeper step towards understanding of cyber incivility, which also helps in the development of intervention strategies to lessen or avoid the negative impact of work-related stressful events on employee well-being.

How Work-Nonwork Conflict Affects Remote Workers' General Health in China: A Self-Regulation Theory Perspective.

Difficulty in balancing the demands of work and nonwork has been shown to be associated with lower physical and psychological health. Grounded on the self-regulation theory, we examined the effect of work-nonwork conflict on general health among employees who transitioned to remote work (remote workers), and we tested whether this association was mediated by impaired self-control capacity. The study further examined the perceived boundary control as a moderator of these associations. We collected two waves of questionnaire data with a one-month interval from 461 remote workers, and the results of regression-based analyses revealed that work-nonwork conflict was negatively related to remote workers' general health through increased self-control capacity impairment. In addition, this indirect effect was weaker for remote workers with higher perceived boundary control than those with lower perceived boundary control. These findings expand our understanding of remote workers' work-nonwork conflict and have practical implications for promoting the general health of remote workers who are experiencing work-nonwork conflict.

Neuromodulatory effects of high-definition theta transcranial alternating current stimulation on the parietal cortex: a pilot study of healthy males.

Introduction: Transcranial alternating current stimulation (tACS) can regulate brain functions by modulating endogenous brain rhythms. Theta-band neural oscillations are associated with memory function. In particular, theta neural oscillatory power evoked in the parietal cortex is closely related to memory retrieval processes. In this study, the immediate effects of high-definition theta transcranial alternating current stimulation (HDθ-tACS) on the human left parietal cortex were investigated using short-latency afferent inhibition (SAI) and electroencephalography (EEG). Methods: Ten subjects participated in this study. We used 6-Hz HD tACS to stimulate the left parietal cortex for 15 min. SAI was calculated, and non-linear dynamic analysis of the EEG was performed to analyze neuronal function after HD θ-tACS. Results: The results showed a significant decrease in SAI (p < 0.05), while the left frontoparietal network was reinforced, leading to brain lateralization after HD θ-tACS. During performance of a memory task, F3 signals showed a significant upward trend in approximate entropy following treatment (p < 0.05). There was also a significant decrease in cross-approximate entropy in the C3-C4 and P3-P4 connections following the intervention (p < 0.05) in a resting eyes-open condition and in the memory task condition. Discussion: In conclusion, HD θ-tACS could alter cholinergic transmission and cortical excitability between the parietal and motor cortices, as well as reinforcing the frontoparietal network and the left-lateralization phenomenon, which may facilitate memory formation, encoding, and consolidation.

Advances of Protein Palmitoylation in Tumor Cell Deaths.

In this comprehensive survey, we delve into the multifaceted role of palmitoylation across various cell death modalities in the oncological context, from its intricate correlations with tumorigenesis, steered by the Asp-His-His-Cys tetrapeptide motif (DHHC) family, to the counter-process of depalmitoylation mediated by enzymes like Palmitoyl protein thioesterase-1 (PPT1). Innovations in detection methodologies have paralleled our growing understanding, transitioning from rudimentary techniques to sophisticated modern methods. Central to our discourse are agents like Ezurpimtrostat (GNS561) and dimeric chloroquine (DC661), promising heralds in palmitoylation-targeted cancer therapy. Collectively, this review accentuates palmitoylation's transformative potential in oncology, foreshadowing groundbreaking therapeutic strategies and deepening our molecular comprehension of cancer dynamics.

Effects of integrated action and sensory observation therapy based on mirror neuron and embodied cognition theory on upper limb sensorimotor function in chronic stroke: a study protocol for a randomised controlled trial.
