Mutual communication intervention for colorectal cancer patient-spousal caregiver dyads: A randomized controlled trial.

OBJECTIVE: Gender could impact the psychosocial outcomes and coping strategies of cancer patients and their spousal caregivers (SCs). This study aims to develop a gender-concerned program for colorectal cancer (CRC) couple-based mutual communication intervention (MCI) and to assess its effectiveness on the intra-couple relationship and the individual functions of the partners. DESIGN: A randomized clinical trial with two study groups was utilized. METHODS: A total of 144 CRC patients and their SCs were randomly assigned to either MCI or usual care (UC) groups, and all of them were required to complete the measurements at baseline and post-intervention. The primary outcome was for mutual communication, and the secondary outcomes included dyadic coping, relationship satisfaction, anxiety, depression, benefit finding and quality of life. The data were analysed by multi-level modelling. RESULTS: The MCI program was feasible and acceptable for Chinese CRC couples and was effective for the improvement of the intra-couple relationship and the individual functions of each partner. CRC patients showed more improvement in mutual communication and dyadic coping than their SCs in the MCI group. Also, this intervention effectiveness was found to be independent of gender. CONCLUSIONS: The MCI program is beneficial for Chinese CRC couple's adaptation outcomes. This suggests that clinical medical staff should consider the gender tendency during the implementation of interventions. More researches are needed to extend the application of the MCI program to different participants (e.g. patients with the diagnosis of other types of cancer and their SCs).

Frontiers and hotspots evolution in cytokine storm: A bibliometric analysis from 2004 to 2022.

Grupp, a prominent researcher in this area, has authored the largest publication count and has the second-highest citation frequency. Research trends and keyword evaluations show that the connection between cytokine storm and COVID-19, as well as cytokine storm treatment, are hot topics in research. Furthermore, research on cytokine storm and COVID-19 sits at the forefront in this area. Conclusion: This study employed bibliometric analysis to create a visual representation of cytokine storm research, revealing current trends and burgeoning topics in this area for the first time. It will provide valuable insights, helping scholars pinpoint critical research areas and potential collaborators.

A couple-based dyadic coping intervention for colorectal cancer patient-spousal caregiver dyads: A randomized controlled study.

PURPOSE: To evaluate the clinical effects of a couple-focused dyadic coping intervention in colorectal cancer (CRC) couples. METHODS: The study was a single-blinded randomized controlled study which 226 CRC couples were recruited and randomized to either the intervention (N = 113) or the control (N = 113) group. All couples received usual care while the six-week dyadic coping intervention was provided to the intervened couples in psycho-education and skill training methods through face-to-face combined with telephone formats. Measurement data, including dyadic coping, marital satisfaction, quality of life and psychological well-being were collected at pre- and post-intervention periods. And multilevel model (MLM) was applied to analyze the effects of the intervention and the role tendency. RESULTS: A total of 173 couples completed the program and post-intervention evaluation. The retention rate was 76.5%. Results from MLM showed that the dyadic coping intervention is effective in promoting levels of dyadic coping (P < 0.001), marital satisfaction (P = 0.042), mental health (P = 0.006), and positive psychological well-being (P < 0.001), and alleviating depression (P = 0.015) in CRC couples. For role tendency, the intervention found to be more effective in CRC spousal caregivers' positive psychological well-being compared to the patients (P = 0.037). CONCLUSION: The couple-based dyadic coping intervention is effective in promoting dyadic coping and improving psychological adjustment in CRC couples. More studies were needed to further evaluate the program and its long-term efficacy in the future. In addition, given the positive effects of the intervention, clinical nursing stuffs may consider implementing such intervention in their routine work while caring for CRC couples.

Effects of Combined Maternal Voice Stimulation and Gravity Feeding Intervention for Low-Birth-Weight Preterm Infants in Neonatal Care.

Background: This study aims to investigate the impact and safety of combining maternal voice stimulation with gravity feeding on low-birth-weight preterm infants. The research focuses on key outcomes such as gastric tube indwelling time, feeding transition time, adequate gastrointestinal nutrition time, recovery of birth weight time, length of hospital stay, and oral motor function in preterm infants. Methods: A total of 150 low birth weight preterm infants meeting inclusion criteria were recruited from the neonatal care unit and randomly assigned to three groups: traditional nasal feeding, gravity feeding with a homemade bracket, and a combined group receiving both gravity feeding and maternal voice stimulation. The groups were compared using parameters such as feeding intolerance incidence, gastric tube indwelling time, feeding transition time, adequate gastrointestinal nutrition time, recovery of birth weight time, hospital stay, and oral motor function. Results: The combined group exhibited a significantly lower incidence of feeding intolerance (26% lower than traditional nasal feeding, 18% lower than gravity feeding, P < .001). The traditional nasal feeding group had the highest incidence at 62%. The combined group showed a shorter indwelling time (19.01 ± 11.67 days), compared to the gravity feeding group (23.50 ± 13.04 days) and the traditional nasogastric feeding group (27.43 ± 11.91 days, P = .001). The combined group had a shorter hospital stay (27.09 ± 14.16 days) compared to the gravity feeding group (32.74 ± 13.32 days) and the traditional nasogastric feeding group (33.84 ± 12.42 days, P = .013). The combined group demonstrated a slightly longer recovery time (11.56 ± 4.08 days) than the gravity feeding group (11.14 ± 4.76 days) but significantly shorter than the traditional nasogastric feeding group (14.44 ± 5.42 days, P = .003). The combined group exhibited the highest improvement in oral motor function at 4 weeks after feeding (17.81 ± 0.39 points), surpassing both the gravity feeding group (16.10 ± 0.23 points) and the traditional nasogastric feeding group (15.15 ± 0.07 points, P < .001). The combined group demonstrated a significantly lower feeding transition time than the traditional nasal feeding group (P < .05) and comparable time to the gravity feeding group (P > .05). All the comparison results were statistically significant. Conclusion: Maternal voice stimulation combined with gravity feeding shows promising positive effects and high safety for low-birth-weight preterm infants. The combined approach outperformed both gravity feeding alone and traditional nasogastric feeding across various critical parameters. These findings support the potential clinical applicability and merit further consideration for wider implementation as a feeding method in neonatal care settings. Clinical Significance: The observed reductions in feeding intolerance, shortened gastric tube indwelling time, and enhanced oral motor function in low-birth-weight preterm infants receiving combined maternal voice stimulation and gravity feeding highlight a promising clinical approach. These improvements signify the potential for earlier oral feeding initiation, shorter hospital stays, and better overall outcomes in the care of these vulnerable infants. Limitations: This study is limited by its single-center design, potential selection bias, and the absence of blinding. Uncontrolled confounding factors may influence results, and long-term outcomes were not assessed. Implications for Practice: Healthcare professionals should cautiously consider the observed benefits of combining maternal voice stimulation with gravity feeding, recognizing the study's limitations. Further research is warranted to validate these findings and explore long-term implications for the care of low-birth-weight preterm infants.

The effect of a couple-based posttraumatic growth intervention in supporting couples coping with colorectal cancer: A randomized controlled study.

OBJECTIVES: To promote posttraumatic growth (PTG) in colorectal cancer (CRC) couples, a couple-based PTG intervention was conducted, and the intervention had previously proved be feasible in CRC couples. The current study was conducted to validate the effects of intervention in CRC couples. METHOD: This is a randomized controlled study that included 174 CRC couples. All participants were randomized to either the intervention (usual care plus 5-week PTG intervention, n = 87) or the control group (usual care, n = 87). Data were collected from CRC couple dyads at baseline and immediately post-intervention periods. Primary outcome refers to positive changes, and secondary outcomes include marital satisfaction, quality of life (QOL), and anxiety and depression. Multilevel modeling was applied to analyze the intervention effects. RESULTS: Participants in the program showed increased PTG, marital satisfaction, and QOL both physically and mentally, and decreased levels of anxiety and depression over time. And spousal caregivers showed greater improvement in marital satisfaction and physical QOL compared with patients. In addition, significant intervention effects were shown in the participants' benefit finding, physical health and depressive symptoms. CONCLUSION: The study confirmed the effect of the PTG intervention on CRC couples' benefit finding, physical health and depressive symptoms. However, this study only measured outcome variables at two time-points. Future studies should add follow-up assessments to evaluate long-term effects of the intervention in CRC couples.

PAS domain containing regulator SLCG_7083 involved in morphological development and glucose utilization in Streptomyces lincolnensis.

BACKGROUND: Streptomyces lincolnensis is well known for producing the clinically important antimicrobial agent lincomycin. The synthetic and regulatory mechanisms on lincomycin biosynthesis have been deeply explored in recent years. However, the regulation involved in primary metabolism have not been fully addressed. RESULTS: SLCG_7083 protein contains a Per-Arnt-Sim (PAS) domain at the N-terminus, whose homologous proteins are highly distributed in Streptomyces. The inactivation of the SLCG_7083 gene indicated that SLCG_7083 promotes glucose utilization, slows mycelial growth and affects sporulation in S. lincolnensis. Comparative transcriptomic analysis further revealed that SLCG_7083 represses eight genes involved in sporulation, cell division and lipid metabolism, and activates two genes involved in carbon metabolism. CONCLUSIONS: SLCG_7083 is a PAS domain-containing regulator on morphological development and glucose utilization in S. lincolnensis. Our results first revealed the regulatory function of SLCG_7083, and shed new light on the transcriptional effects of SLCG_7083-like family proteins in Streptomyces.

An integrated intervention programme for couples facing colorectal cancer: A randomized controlled trial.

BACKGROUND: Under the guidance of a preliminary Live with Love Conceptual Framework, a Caring for Couples Coping with Colorectal Cancer (4Cs: CRC) programme was designed specifically for colorectal cancer couples. The objectives of this study included examining the efficacy of the programme for couples adapting to colorectal cancer and comparing the effects of different intervention delivery modes (online, face-to-face and blended) on couple outcomes. METHODS: A four-arm randomized controlled trial was conducted among Chinese colorectal cancer couples. Couples were randomly assigned to an online intervention, a face-to-face intervention, a blended intervention or a control group. Self-efficacy, dyadic coping, communication and dyadic outcomes (physical and mental health, negative and positive emotions and marital satisfaction) were evaluated at baseline and 6 weeks later. Analysis of variance (ANOVA) and repeated measures ANOVA were employed to assess between-group differences and within-group effects in the four groups, respectively. RESULTS: A total of 179 couples completed the 6-week study and post-study assessments. The intervention showed generally medium-to-large effects across multiple measured outcomes, including self-efficacy, dyadic coping, communication, mental health, negative emotions and positive emotions for both patients and spouse caregivers. Additionally, interventions delivered through different modes produced equally significant effects on couple outcomes. CONCLUSIONS: The integrated intervention programme is effective in improving cancer adaptation in colorectal cancer couples. Long-term follow-up and a mix of quantitative and qualitative assessments are crucial for further evaluation of the programme. TRIAL REGISTRATION: Retroactive registration is under review.

Mutual communication processes within Chinese colorectal cancer patient-spousal caregiver dyads: A qualitative study of taking gender into account.

PURPOSE: Mutual communication within cancer couples is a complex process. More research is needed to explore the complex process of mutual communication and its nuances presented by various factors in different culture contexts. Gender, a factor embedded in marital relationships, is an important consideration. We thus aim to explore the mutual communication process within Chinese colorectal cancer couples and take gender into account. METHODS: A qualitative study was conducted by interviewing 20 colorectal cancer patients and 15 spousal caregivers. Inductive thematic analysis was used to analyze the transcripts. RESULTS: Three themes (mutual communication and support interaction, communication quality, and foundation of mutual communication and collaboration) were developed. Gender was found to have specific impact on emotional disclosure and communication challenges. A preliminary framework of "smile" was constructed to demonstrate the relationship among the three themes and the relationships between the three themes and dyads' psychosocial adaptation to colorectal cancer. CONCLUSIONS: Study findings demonstrate complex mutual communication processes within colorectal cancer couples and the impact of gender. The findings will contribute to developing more effective colorectal cancer couple-based mutual communication interventions. Health practitioners are suggested to improve mutual communication within colorectal cancer couples in three aspects: relational topics, emotional disclosure and communication skills. Guiding couples to deal with each theme and the relationship among the themes simultaneously is helpful for them to return and smile to their normal life.

The impact of self-perceived burden, caregiver burden, and dyadic coping on negative emotions in colorectal cancer patient-spousal caregiver dyads: a dyadic analysis.

Objective: To explore the correlation between dyadic coping, self-perceived burden, caregiver burden, and anxiety/depression in colorectal cancer patient-spousal caregiver dyads. Methods: This study surveyed 200 colorectal cancer patient-spousal caregiver dyads from August 2022 to December 2022. It evaluated self-perceived burden (only for patients), caregiver burden (only for spousal caregivers), dyadic coping, anxiety, and depression. It analyzed data through Pearson's correlation and the actor-partner interdependence mediation model. Results: Self-perceived burden and caregiver burden were significantly associated with the anxiety/depression of both individuals in colorectal cancer patient-spousal caregiver dyads; patients' dyadic coping was associated with self-perceived burden and caregiver burden; caregivers' dyadic coping was only associated with patients' dyadic coping and depression. There was an actor-partner mediating effect of self-perceived burden between dyadic coping and anxiety/depression, but there was only a partner-mediating effect of caregiver burden between dyadic coping and anxiety/depression. Conclusion: This study confirmed the interrelationship between self-perceived burden, caregiver burden, dyadic coping, anxiety, and depression. Self-perceived burden and caregiver burden mediated the relationship between dyadic coping and anxiety/depression in colorectal cancer patient-spousal caregiver dyads. This suggests dynamic interventions for self-perceived burden and caregiver burden can be implemented to improve anxiety/depression in both partners based on maintaining healthy dyadic coping between colorectal cancer patient-spousal caregiver dyads.

Ectomycorrhizal community associated with Cedrus deodara in four urban forests of Nantong in East China.

Ectomycorrhizal (ECM) fungi play fundamental roles in host plant growth and terrestrial ecosystems. Cedrus deodara is cultivated in several regions in China, has high ecological, economic and medicinal value, for its afforestation and providing timber and wood oil. Here, we investigated ECM colonization status of four urban C. deodara forests in Nantong, East China. We also characterized soil spore banks by conducting bioassay experiments using soils collected from these forests. In total, we identified 19 ECM fungal species, of which 13 species were found in mature forests and 9 species were identified in bioassay experiments, with only 3 species shared. Soil pH and available P content had significant effects on species occurrence in both mature trees and bioassay seedlings on local scales. ECM communities clearly (A = 0.391, p = 0.006) separated mature forests from spore banks. Thelephoracae was the richest family we detected associated with C. deodara, while Trichophaea sp. was the most dominant in mature forests, and Wilcoxina sp. was dominant in spore banks. ECM richness affected the growth of bioassay seedlings, especially after inoculation with 2 ECM species, promoting root growth, significantly (F = 3.028, p = 0.050), but it had no effects on shoots (F = 1.778, p = 0.177). No effect of inoculation rate was found on seedlings growth. To conserve this important tree species, the ECM fungi that are associated with it should be considered.

Clinical Characteristics and Genotyping of Pediatric Adenovirus Pneumonia Disease and Coinfection in Southeast China.

Introduction: Human adenovirus (HAdV) is a common pathogen that can cause acute respiratory infections (ARIs) in children. Adenovirus pneumonia is the most severe respiratory disease associated with HAdV. Objective: We aimed to investigate the clinical characteristics of children hospitalized with adenovirus pneumonia in Quanzhou, China, in 2019. We also sought to determine the viral genotype in these cases and explore cases associated with severe adenovirus pneumonia. Methods: We collected oropharyngeal swabs from 99 children who were hospitalized with pneumonia in Quanzhou Women and Children's Hospital, these samples were tested for the presence of HAdV. Genotyping of the viruses was performed by real-time polymerase chain reaction. Logistic regression analysis was employed to analyze risk factors related to severe adenovirus pneumonia. The epidemiological data were examined using the Statistical Package for Social Sciences software (SPSS). Results: Among the 99 patients in our study, the median age was 21 months. We observed a 4% mortality rate among those diagnosed with adenovirus pneumonia. Adenovirus pneumonia often presents as a coinfection. Lactate dehydrogenase and neutrophil percentages of WBC's were significantly increased in patients with severe adenovirus pneumonia compared with mild HAdV disease. The predominant viral genotypes identified were type 3 and type 7. Conclusions: In the Quanzhou area of southeast China, the incidence of adenovirus pneumonia was found to be high among children younger than two years old. Type 7 HAdV was identified as the primary pathogen. A long duration of fever, dyspnea and digestive system complications were risk factors for severe adenovirus pneumonia after HAdV infection. Clinical Trial Registration number: ChiCTR2200062358.

Interplay between intensity-dependent dispersion and Kerr nonlinearity on the soliton formation.

A generalized nonlinear Schrödinger equation is studied with the interplay between Kerr nonlinearity and intensity-dependent dispersion. The supported soliton solutions are characterized analytically in different families by the pseudo-potential method, in terms of Maimistov and Cuspon solitons for different ratio between the intensity-dependent dispersion and Kerr nonlinearity. Direct numerical simulations also agree with our analytical formulas. In addition to the well-studied Kerr-type nonlinearity, our results reveal an unexplored scenario with the introduction of the nonlinear corrections to wave dispersion.

Feasibility and preliminary effect of a couple-based posttraumatic growth intervention for colorectal cancer couples: A randomized controlled pilot study.

BACKGROUND: Colorectal cancer (CRC) causes severe physical and psychological impacts on the patients as well as their spousal caregivers. To facilitate the psychological adaptation of the CRC suffered couples, a couple-based posttraumatic growth (PTG) intervention was developed based on the PTG affective-cognitive processing model. The feasibility, acceptability and preliminary effect of this intervention were tested. METHODS: A pre-post randomized controlled pilot trail was conducted for Chinese couples coping with CRC. Participants in the intervention group were provided five weekly sessions consecutively, while those in the control group were treated with usual care during the testing period. Outcomes were described as positive changes (PTG, benefit finding [BF]), marital satisfaction, quality of life and anxiety and depression. Qualitative method was also used to evaluate the programme participating sense of the couples. RESULTS: The rate of programme recruitment and programme retention amounts to 78.6% and 87.5%, respectively. The participants have reported overall satisfaction for the programme attendance and have suggested detailed diet guidance. Significant effects were revealed in the outcomes for the CRC couples, including PTG, marital satisfaction, BF, physical and mental health and anxiety and depression. CONCLUSION: The study confirmed the feasibility and preliminary positive effect of the couple-based PTG intervention for the CRC couples. However, in order to extend it in more general applications, large-scale researches are warranted. PRACTICAL IMPLICATION: The couple-based intervention is effective for couples coping with CRC. Clinicians should take the components of the intervention into consideration in their practice work for the CRC couples.

Autofluorescence spectral analysis for detecting urinary stone composition in emulated intraoperative ambient.

The prevalence and disease burden of urolithiasis has increased substantially worldwide in the last decade, and intraluminal holmium laser lithotripsy has become the primary treatment method. However, inappropriate laser energy settings increase the risk of perioperative complications, largely due to the lack of intraoperative information on the stone composition, which determines the stone melting point. To address this issue, we developed a fiber-based fluorescence spectrometry method that detects and classifies the autofluorescence spectral fingerprints of urinary stones into three categories: calcium oxalate, uric acid, and struvite. By applying the support vector machine (SVM), the prediction accuracy achieved 90.28 % and 96.70% for classifying calcium stones versus non-calcium stones and uric acid versus struvite, respectively. High accuracy and specificity were achieved for a wide range of working distances and angles between the fiber tip and stone surface in an emulated intraoperative ambient. Our work establishes the methodological basis for engineering a clinical device that achieves real-time, in situ classification of urinary stones for optimizing the laser ablation parameters and reducing perioperative complications in lithotripsy.

Ciprofloxacin degradation performances and mechanisms by the heterogeneous electro-Fenton with flocculated fermentation biochar.

Antibiotic fermentation residue flocculated by polymeric ferric sulfate (PFS) has been classified as a "hazardous waste" in China. In this study, it was recycled into antibiotic fermentation residue biochar (AFRB) by pyrolysis and used as a heterogeneous electro-Fenton (EF) catalyst for ciprofloxacin (CIP) degradation. The results show that PFS was reduced to Fe0 and FeS during pyrolysis, which was beneficial for the EF process. The AFRB with mesoporous structures exhibited soft magnetic features, which were convenient for separation. CIP was completely degraded within 10 min by the AFRB-EF process at an initial concentration of 20 mg/L. Increasing the working current and catalyst dosage within a certain range could improve the degradation rate. ·OH and O2·- were the dominant reactive oxygen species that played critical roles for CIP degradation. The antibacterial groups of CIP have been destroyed by the heterogeneous electro-Fenton process and its toxicity was negligible. The AFRB showed satisfactory performance, even though it was recycled five times. This study provide new insights into the resourceful treatment of antibiotic fermentation residues.

A couple-based dyadic coping intervention for couples coping with colorectal cancer: A pilot feasibility study.

PURPOSE: Compared to individual coping, dyadic coping has significant impact on cancer adaptation in cancer couples. Few intervention studies have focused on dyadic coping in colorectal cancer couples. The purpose of this study was to test the feasibility, acceptability, and preliminary efficacy of a Systemic Transactional Model-guided, couples-based dyadic coping intervention program for colorectal cancer couples. METHODS: A pre-/post-test single-group pilot study was conducted among Chinese colorectal cancer couples. Couples received six intervention sessions delivered by researchers via face-to-face or telephone. Recruitment and retention rates were calculated to assess program feasibility. Quantitative and qualitative post-intervention program evaluation were evaluated to assess acceptability. Additionally, effect sizes were calculated using Dyadic Coping Inventory, Dyadic Adjustments Scale, Medical Outcomes Study 12-item Short-Form, Benefit-Finding Scale, and Hospital Anxiety and Depression Scale to assess preliminary program efficacy. RESULTS: Of the 31 eligible couples approached, 21 dyads completed the baseline questionnaire, with 16 dyads completing the intervention and post-intervention assessments. Recruitment (67.7%) and retention (76.2%) rates supported the feasibility of the intervention program. Program acceptability was supported by participant satisfaction with the program. The intervention had small-to-medium effect sizes (Cohen's d = 0.19-0.48) in improving dyadic coping and most cancer adaptation outcomes for both patients and their spousal caregivers, validating the preliminary efficacy of the program. CONCLUSIONS: The couples-based dyadic coping intervention is feasible, acceptable, and effective for improving dyadic coping levels and cancer adaptation in colorectal cancer couples. Further examination of this intervention program in a large-scale randomized controlled trial is required.

Statistical Measurements and Club Effects of High-Quality Development in Chinese Manufacturing.

Advanced manufacturing is the pillar for building a modern economic system. We measured the level of high-quality development of manufacturing (HQDM) in China, and found that it has gone through the three stages of expansion, cultivation, and promotion. Spatially, it is characterized as "high in the east, low in the west" and "fast in the west, slow in the east", and presents non-equilibrium characteristics. To overcome the subjective bias introduced by artificially set clubs, we utilize a data-driven nonlinear time-varying factor model for clustering into four convergent clubs, where provinces with higher intensity of environmental regulation and environmental preference tend to move closer to the clubs with a higher level of HQDM. We reveal the convergence patterns and regional differences in HQDM, which provides a new perspective for determining the trends of high-quality manufacturing development, thus allowing for policy recommendations targeted at narrowing the manufacturing development gap.

Veratramine ameliorates pain symptoms in rats with diabetic peripheral neuropathy by inhibiting activation of the SIGMAR1-NMDAR pathway.

CONTEXT: Veratramine may have a potential therapeutic effect for diabetic peripheral neuropathy (DPN). OBJECTIVE: To evaluate whether veratramine ameliorates neuropathic pain in a rat diabetic model. MATERIALS AND METHODS: Sprague-Dawley rats were used for a diabetic model induced by a streptozotocin + high-fat diet. Two months after the induction of the diabetic model, the rats with DPN were screened according to the mechanical pain threshold. The rats with DPN were divided into a model group (n = 12) and a treated group (n = 12). Rats with diabetes, but without peripheral neuropathy, were used in the vehicle group (n = 9). The treatment group received 50 µg/kg veratramine via the tail vein once a day for 4 weeks. During modelling and treatment, rats in all three groups were fed a high-fat diet. RESULTS: The mechanical withdrawal threshold increased from 7.5 ± 1.9 N to 17.9 ± 2.6 N in DPN rats treated with veratramine. The tolerance time of the treated group to hot and cold ectopic pain increased from 11.8 ± 4.2 s and 3.4 ± 0.8 s to 20.4 ± 4.1 s and 5.9 ± 1.7 s, respectively. Veratramine effectively alleviated L4-L5 spinal cord and sciatic nerve pathological injury. Veratramine inhibited the expression of SIGMAR1 and the phosphorylation of the N-methyl-d-aspartate receptor (NMDAR) Ser896 site in spinal cord tissue, as well as inhibited the formation of SIGMAR1-NMDAR and NMDAR-CaMKII complexes. DISCUSSION AND CONCLUSIONS: Veratramine may alleviate the occurrence of pain symptoms in rats with DPN by inhibiting activation of the SIGMAR1-NMDAR pathway.

Potato (Solanum tuberosum L.) Leaf Extract Concentration Affects Performance and Oxidative Stress in Green Peach Aphids (Myzus persicae (Sulzer).

This study was conducted to determine the aphicidal effect of a leaf extract of the Atlantic potato cultivar on the performance of green peach aphids. Three concentrations of the leaf extract (100, 75, and 50% potato extract), synthetic pesticide (Beta cypermethrin 4.5%), and distilled water (control) treatments were applied in a greenhouse experiment. The results showed that the synthetic pesticide, which was used as a standard check, caused the maximum aphid mortality, followed by the 100% potato leaf extract. Compared with the other botanical treatments, the 100% extract produced low mean rates of survival, aphids' average daily reproduction, the number of nymphs per plant, and the number of nymphs per adult. This treatment also increased the accumulation of hydrogen Peroxide (H2O2) and malondialdehyde (MDA), glutathione-s-transferase, mixed-function oxidase, and carboxylesterase content in the green peach aphid. Moreover, the 100% extract also protected the host plants against green peach aphid attacks by demonstrating higher chlorophyll content, net photosynthesis, above-ground fresh weight, and above-ground dry weight of the host plant. This study demonstrates that the highest concentration of potato (Atlantic cultivar) leaf extract (100% extract) could be used as the appropriate dosage for the control of green peach aphids on potatoes, which could greatly reduce the use of synthetic insecticides and promote ecosystem sustainability.

Clinical Characteristics and Gene Mutation Analysis of Poststroke Epilepsy.

Epilepsy is one of the most common brain disorders worldwide. Poststroke epilepsy (PSE) affects functional retrieval after stroke and brings considerable social values. A stroke occurs when the blood circulation to the brain fails, causing speech difficulties, memory loss, and paralysis. An electroencephalogram (EEG) is a tool that may detect anomalies in brain electrical activity, including those induced by a stroke. Using EEG data to determine the electrical action in the brains of stroke patients is an effort to measure therapy. Hence in this paper, deep learning assisted gene mutation analysis (DL-GMA) was utilized for classifying poststroke epilepsy in patients. This study suggested a model categorizing poststroke patients based on EEG signals that utilized wavelet, long short-term memory (LSTM), and convolutional neural networks (CNN). Gene mutation analysis can help determine the cause of an individual's epilepsy, leading to an accurate diagnosis and the best probable medical management. The test outcomes show the viability of noninvasive approaches that quickly evaluate brain waves to monitor and detect daily stroke diseases. The simulation outcomes demonstrate that the proposed GL-GMA achieves a high accuracy ratio of 98.3%, a prediction ratio of 97.8%, a precision ratio of 96.5%, and a recall ratio of 95.6% and decreases the error rate 10.3% compared to other existing methods.
