Atomic Layer-Deposited Silane Coupling Agent for Interface Passivation of Quantum Dot Light-Emitting Diodes.

Inserting an insulating layer between the charge transport layer (CTL) and quantum dot emitting layer (QDL) is widely used in improving the performance of quantum dot light-emitting diodes (QLEDs). However, the additional layer inevitably leads to energy loss and joule heat. Herein, a monolayer silane coupling agent is used to modify the said interfaces via the self-limiting adsorption effect. Because the ultrathin layers induce negligible series resistance to the device, they can partially passivate the interfacial defects on the electron transport side and help confine the electrons within the QDL on the hole transport side. These interfacial modifications can not only suppress the nonradiative recombination but also slow down the aging of the hole transport layer. The findings here underline a low-temperature adsorption-based strategy for effective interfacial modification which can be used in any layer-by-layer device structures.

Bereavement dyadic coping questionnaire: Development and validation.

Most theories and empirical studies of bereavement coping focus on the individual, although researchers have highlighted the importance of family-level coping and proposed the concept of bereavement dyadic coping (BDC). We developed and validated a 25-item Bereavement Dyadic Coping Questionnaire (BDCQ). The procedure includes item generation, expert review, and examination of the psychometric properties in 241 bereaved persons in bereaved families from China. Factor analysis revealed four factors: direct loss-oriented, indirect loss-oriented, restoration-oriented, and collaborative. The questionnaire had satisfactory internal consistency, test-retest reliability, and convergent and divergent validity. The BDCQ is the first of its kind to measure dyadic coping in the context of bereavement, permitting future quantitative explorations of bereavement dyadic coping and its influence on bereaved individuals and families.

Prenatal heavy metal exposure and pediatric asthma, allergic rhinitis, atopic dermatitis: a systematic review and meta-analysis.

OBJECTIVE: We review the prevalence of allergic diseases in children across prenatal exposures to heavy metals. METHODS: This systematic review and meta-analysis is registered in the PROSPERO database (CRD42023478471). A comprehensive search of PubMed, Web of Science, Medline and Cochrane library was conducted from the database inception until 31 October 2023. The Newcastle-Ottawa Quality Assessment Scale (NOS) was used to assess the quality of included studies. We used a random-effects model to summarize the effects from the studies. RESULTS: A total of 16 studies were included, 120,065 mother-child pairs enrolled. The NOS scores indicated that the quality of the literature included in the study was of a high standard. CONCLUSION: The final results indicate that prenatal exposure to Pb increased the incidence of wheeze and Eczema in infants, and exposure to Ni and CD increased the incidence of AD in infants.

Objective: To investigate the biological safety of commercially available natural rubber latex and synthetic polyurethane condoms. Methods: Natural rubber latex condom brands of A1 and A2 and polyurethane condom brands of B1 and B2 were purchased from large chain pharmacies in Chengdu, with three packages randomly selected for each brand. The study assessed the toxic effects of condom extracts on L-929 mouse fibroblasts according to GB/T standards. Gross observation and histopathological evaluation were conducted to assess the irritation reactions of condoms on the vagina and penis of rabbits (3 rabbits were used for each brand), as well as their sensitization effects on guinea pig skin. Additionally, the impact of continuous perfusion of condom extracts of the vaginas of SD rats for 30 days on their reproductive systems was evaluated, following GB/T standards (5 rats were used for each brand). Results: Extracts from natural rubber latex condom brands A1 and A2, at concentrations of 100% and 50%, exhibited significant cytotoxicity, with optical density (OD) values being significantly lower than those of the blank control group and the polyurethane condom brands B1 and B2 (P<0.01). There was no significant difference in cell morphology and OD values between the extracts of B1 and B2 and the blank control group (P>0.05). Vaginal congestion was found in 3 rabbits from A1 group and 1 rabbit from the A2 group, while no obvious congestion was noted in rabbits from the B1 and the B2 groups. Histopathological examination showed scattered inflammatory cell infiltration in the vaginal tissue of 3 rabbits from the A1 group and 2 rabbits from the A2 group, and slight congestion in the blood vessels of the lamina propria. No obvious pathological changes were observed in the vaginal tissue of polyurethane brand rabbits. Two rabbits from the A1 group and 1 rabbit from the A2 group showed transient and mild erythema on the penis during the experiment. Histopathological examination showed that 1 rabbit from A1 group had small foci of pericapillary lymphocytes in the dermis of the penis, while no significant pathological changes were observed in the penile tissue of A2, B1, and B2 groups. After 30 days of continuous vaginal perfusion with condom extract, 3 rats in A1 group and 2 rats in the A2 group had uterine congestion, with the degree of congestion being lower in the A2 group. No significant congestion or pathological changes were observed in the vaginal and penile tissues of rabbits, or in the uterine tissues of rats from the polyurethane groups. None of the 4 groups of guinea pigs showed significant skin allergic reactions to the condom extracts. Conclusion: Significant differences in biosafety exist among condoms of various materials and brands. To ensure product safety, it is crucial to strengthen quality control and regulatory oversight after condoms become commercially available.

Differential Effects of an Integrated Community-Based End-Of-Life Support Team (ICEST) Model for Terminally Ill Older Adults on Spousal and Adult-Children Caregivers.

Backgrounds: Family caregivers (FCs) play an essential role in delivering home-based end-of-life care. However, little is known about FCs'' experiences when undertaking this role. The integrated community end-of-life support team (ICEST) is a needs-driven, home-based, family-centered care model in Hong Kong. We evaluated its effects on FCs and compared outcomes for spouses and adult children. Method: A multicenter pre-post-test study was conducted. Eligible participants were primary FCs of terminally ill older adults (age ≥ 60) who had a life expectancy of ≤12 months. Baseline (T0) and three-month post-intervention (T1) outcome measures included FCs'' caregiving strain, psychological distress, perceived external support, intimate relationships, and communications regarding care planning. Results: A sample of 628 FCs were enrolled at T0, and 40.0% completed the T1 assessments. The ICEST model was effective in reducing caregiving strain, depression, and worries about patients, whilst there were improvements in agreement about care planning with patients, and perceived external supports. At T0, spouses held more negative perceptions of caregiving and faced fewer adjustment demands than adult children. Compared with spouses, adult children were more intimate with patients. Between T0 and T1, spouses experienced a greater reduction in worries about patients, than adult children. Conclusions: The ICEST model contributed to better outcomes, individually and relationally, for FCs, regardless of relationship type. Spouses and adult children faced different challenges while delivering home-based end-of-life care. Effective interventions should modify the negative perceptions of caregiving in spousal caregivers and enable adult children to deal with multiple tasks and complex expectations.

Unveiling the impact of interprofessional education on shaping students' interprofessional identity and collaboration perception: a mixed-method study.

BACKGROUND: Interprofessional education (IPE) has the potential to shape students' collaboration perception and interprofessional identity but remains understudied. This study aims to understand the effects of the IPE program as a contextual trigger to promote collaboration perception change and interprofessional identity formation among healthcare professional students. METHODS: Using concurrent triangulation mixed-methods, we examined the relationship between collaboration perception and interprofessional identity change among health profession students (N = 263), and explored their perspectives on how their IPE experiences influenced their perception and identity. Participants completed the Interdisciplinary Education Perception Scale and Extended Professional Identity Scale and responded to open-ended questions before and after the IPE intervention. Pearson's correlation, t-tests, regression (quantitative), and thematic analysis (qualitative) were conducted. RESULTS: Teams with initially lower collaboration perception (M = 3.59) and lower interprofessional identity (M = 3.59) showed a significant increase in collaboration perception (M = 3.76, t = 2.63; p = .02) and interprofessional identity (M = 3.97, t = 4.86; p < .001) after participating in IPE. The positive relationship between collaboration perception and interprofessional identity strengthened after participating in IPE, as evident from the correlation (Time 1: r = .69; p < .001; Time 2: r = .79; p < .001). Furthermore, collaboration perception in Time 1 significantly predicted the variance in interprofessional identity at Time 2 (ß = 0.347, p < .001). Qualitative findings indicated that 85.2% of students expressed that IPE played a role in promoting their interprofessional identity and collaboration attitudes. CONCLUSIONS: Incorporating the IPE program into the curriculum can effectively enhance students' collaboration perception and interprofessional identity, ultimately preparing them for collaborative practice in the healthcare system. By engaging students in interprofessional teamwork, communication, and joint decision-making processes, the IPE program provides a valuable context for students to develop a sense of belonging and commitment to interprofessional collaboration.

Heterogeneous fibroblasts contribute to fibrotic scar formation after spinal cord injury in mice and monkeys.

Spinal cord injury (SCI) leads to fibrotic scar formation at the lesion site, yet the heterogeneity of fibrotic scar remains elusive. Here we show the heterogeneity in distribution, origin, and function of fibroblasts within fibrotic scars after SCI in mice and female monkeys. Utilizing lineage tracing and single-cell RNA sequencing (scRNA-seq), we found that perivascular fibroblasts (PFs), and meningeal fibroblasts (MFs), rather than pericytes/vascular smooth cells (vSMCs), primarily contribute to fibrotic scar in both transection and crush SCI. Crabp2 + /Emb+ fibroblasts (CE-F) derived from meninges primarily localize in the central region of fibrotic scars, demonstrating enhanced cholesterol synthesis and secretion of type I collagen and fibronectin. In contrast, perivascular/pial Lama1 + /Lama2+ fibroblasts (LA-F) are predominantly found at the periphery of the lesion, expressing laminin and type IV collagen and functionally involved in angiogenesis and lipid transport. These findings may provide a comprehensive understanding for remodeling heterogeneous fibrotic scars after SCI.

Comparative analysis of symptom burdens and influential factors among diverse terminally-ill patients.

BACKGROUND: The suffering experienced by terminally-ill patients encompasses physiological, psychosocial and spiritual dimensions. While previous studies have investigated symptom burden intensity for specific disease groups, such as cancer or heart failure patients, a research gap exists in understanding major distressing symptoms among diverse terminally-ill patients. This study assessed symptom burden intensity and explored its influential factors among diverse patient disease groups. METHODS: This cross-sectional study utilized the baseline Integrated Palliative care Outcome Scale (IPOS) assessment data. The study participants were terminally-ill patients enrolled in an end-of-life care (EoLC) intervention in Hong Kong. Statistical methods including relative importance index (RII), one-way analysis of variance (ANOVA), and generalized linear regression (GLR) were employed. RESULTS: Final sample consisted of 1,549 terminally-ill patients (mean age =77.4 years, SD =11.6). The five top-rated distressing symptoms among these patients, revealed by the RII analysis, were poor mobility (RII =64.4%), family anxiety (RII =63.5%), sharing feelings with family/friends (RII =61.4%), weakness/lack of energy (RII =58.1%), and hardly feeling at peace (RII =50.7%). One-way ANOVA showed significant differences among the eight disease groups in perceived physical and emotional symptom burden intensity (P<0.05). Analysis of RII symptom scores for each disease group revealed that poor mobility was rated as the most distressing symptom (RII =85.1-62.9%) by patients with motor neurone disease, Parkinson's disease, heart failure, dementia, end-stage renal disease and other serious diseases (including stroke, hematological disease, multiple sclerosis and liver diseases). Perceived family anxiety (RII =66.1%) and shortness of breath (RII =63.8%) were the most distressing symptoms for cancer patients and those with chronic obstructive pulmonary disease, respectively. GLR analysis showed that illness type is the most significant factor influencing the perceived burden intensity in terms of the IPOS total and subscale scores of physical symptoms, emotional symptoms and communication/practical issues. Demographic characteristics such as age, gender, marital status and co-residing status were also identified as influential factors of various symptom categories. However, patients' educational level and relationship with primary caregiver did not significantly influence any perceived symptom burden. CONCLUSIONS: This study provides valuable insights into the symptom burdens experienced by diverse patient disease groups at end-stage of life. The findings highlight the major distressing symptoms of poor mobility, family anxiety, and shortness of breath. Addressing these symptoms is crucial in improving the quality of care for terminally-ill patients. Furthermore, the study identifies influential factors that can affect the perceived intensity of symptom burden, primarily the main type of terminal illness and patient's age. Tailored care support and improved clinical care should be implemented, particularly for high-risk groups such as patients with non-cancer terminal illnesses and older aged patients. These findings contribute to existing literature and emphasize the need for comprehensive and individualized care in EoLC.

What makes advance care planning discussion so difficult? A systematic review of the factors of advance care planning in healthcare settings.

OBJECTIVES: Existing systematic reviews related to advance care planning (ACP) largely focus on specific groups and intervention efficacy or are limited to contextual factors. This research aims to identify the modifiable factors perceived by different users of ACP in healthcare settings and inform healthcare professionals about the factors affecting ACP practice. METHODS: Five English-language databases (ProQuest, PubMed, CINAHL Plus, Scopus, and Medline) and two Chinese-language databases (CNKI and NCL) were searched up to November 2022. Empirical research identifying factors related to ACP in healthcare settings was included. ACP is defined as a discussion process on future end-of-life care. Thematic synthesis was performed on all included studies. RESULTS: A total of 1871 unique articles were screened; the full texts of 193 were assessed by 4 reviewers, and 45 articles were included for analysis. Twenty-two (54%) studies were qualitative, 15 (33%) were quantitative, and 6 (13%) used mixed methods. Foci varied from 28 (62%) studies on a single subject group (either patient, family, or physician), 11 (25%) on 2 subject groups (either patient and family or patient and healthcare professional), and 6 (13%) covered 3 subject groups (patient, family, and healthcare professional). Among the 17 studies involving more than 1 subject group, only 2 adopted a dyadic lens in analysis. Complex interwoven factors were categorized into (1) intrapersonal factors, (2) interpersonal factors, and (3) socio-environmental factors, with a total of 11 themes: personal belief, emotions, the burden on others, timing, responsiveness, relationship, family dynamics, experience, person taking the lead, culture, and support. SIGNIFICANCE OF RESULTS: Patients, families, and healthcare professionals are the essential stakeholders of ACP in healthcare settings. Factors are interweaved among the intrapersonal, interpersonal, and socio-environmental dimensions. Research is warranted to examine the dynamic interactions of the 3 essential stakeholders from a multidimensional perspective, and the mechanism of the interweaving of factors.

Dissecting the Genetic Basis of Yield Traits and Validation of a Novel Quantitative Trait Locus for Grain Width and Weight in Rice.

Grain yield in rice is a complex trait and it is controlled by a number of quantitative trait loci (QTL). To dissect the genetic basis of rice yield, QTL analysis for nine yield traits was performed using an F2 population containing 190 plants, which was developed from a cross between Youyidao (YYD) and Sanfenhe (SFH), and each plant in the population evaluated with respect to nine yield traits. In this study, the correlations among the nine yield traits were analyzed. The grain yield per plant positively correlated with six yield traits, except for grain length and grain width, and showed the highest correlation coefficient of 0.98 with the number of filled grains per plant. A genetic map containing 133 DNA markers was constructed and it spanned 1831.7 cM throughout 12 chromosomes. A total of 36 QTLs for the yield traits were detected on nine chromosomes, except for the remaining chromosomes 5, 8, and 9. The phenotypic variation was explained by a single QTL that ranged from 6.19% to 36.01%. Furthermore, a major QTL for grain width and weight, qGW2-1, was confirmed to be newly identified and was narrowed down to a relatively smaller interval of about ~2.94-Mb. Collectively, we detected a total of 36 QTLs for yield traits and a major QTL, qGW2-1, was confirmed to control grain weight and width, which laid the foundation for further map-based cloning and molecular design breeding in rice.

Harnessing developmental dynamics of spinal cord extracellular matrix improves regenerative potential of spinal cord organoids.

Neonatal spinal cord tissues exhibit remarkable regenerative capabilities as compared to adult spinal cord tissues after injury, but the role of extracellular matrix (ECM) in this process has remained elusive. Here, we found that early developmental spinal cord had higher levels of ECM proteins associated with neural development and axon growth, but fewer inhibitory proteoglycans, compared to those of adult spinal cord. Decellularized spinal cord ECM from neonatal (DNSCM) and adult (DASCM) rabbits preserved these differences. DNSCM promoted proliferation, migration, and neuronal differentiation of neural progenitor cells (NPCs) and facilitated axonal outgrowth and regeneration of spinal cord organoids more effectively than DASCM. Pleiotrophin (PTN) and Tenascin (TNC) in DNSCM were identified as contributors to these abilities. Furthermore, DNSCM demonstrated superior performance as a delivery vehicle for NPCs and organoids in spinal cord injury (SCI) models. This suggests that ECM cues from early development stages might significantly contribute to the prominent regeneration ability in spinal cord.

Interspecific variations in growth, physiology and Cd accumulation between Populus deltoides and P. × canadensis in response to Cd pollution under two soil types.

Both acid and alkaline purple soils in China are increasingly affected by Cd contamination. The selection of fast-growing trees suitable for remediating different soil types is urgent, yet there is a severe lack of relevant knowledge. In this study, we conducted a controlled pot experiment to compare the growth, physiology, and Cd accumulation efficiency of two widely recognized poplar species, namely Populus deltoides and P. × canadensis, under Cd contamination (1 mg kg-1) in acid and alkaline purple soils. The objective was to determine which poplar species is best suited for remediating different soil types. Our findings are as follows: (1) the total biomass of both poplars remained largely unaffected by Cd pollution in both soil types. Notably, under Cd pollution, the total biomass of P. deltoides in acid purple soil was 1.53 times greater than that in alkaline purple soil. (2) Cd pollution did not significantly induce oxidative damage in the leaves of either poplar species in both soil types. However, in acid purple soil, Cd contamination led to a 21% increase in NO3- concentration and a 44% increase in NH4+ concentration in P. × canadensis leaves, whereas in alkaline purple soil, it led to a 59% increase in NH4+ concentration in P. deltoides leaves. (3) Cd concentrations in all root orders of P. × canadensis were significantly higher than those in P. deltoides, especially in the first three root orders, under alkaline purple soil. The total Cd accumulation by P. × canadensis in Cd-polluted alkaline purple soil was 2.18 times higher than that in Cd-polluted acid purple soil, a difference not observed in P. deltoides. (4) redundancy analysis indicated that the sequestration effect of higher soil organic matter on Cd availability in acid purple soil was more pronounced than the release effects caused by lower pH. In conclusion, P. × canadensis is better suited for remediating alkaline purple soil due to its higher capacity for Cd uptake, while P. deltoides is more suitable for remediating Cd-contaminated acid purple soil due to its better growth conditions and greater Cd enrichment capability.

Influencing factors of nurses' short-term bereavement reactions after patient death.

An online cross-sectional survey was performed among 181 nurses in mainland China who experienced their most recent patient death within the last month. Multivariate linear regressions were used following bivariate analysis to identify influencing factors for their short-term professional bereavement reactions. More intensive reactions were associated with the nurse's fewer experiences of patient death; the nurse's employment in the intensive care unit rather than the emergency, oncology, geriatrics, or internal medicine departments; and the patient experiencing more pain in the last few days. Higher reaction scores were also reported by nurses who lost the patient more than 1 week prior.

Mimicked Spinal Cord Fibers Trigger Axonal Regeneration and Remyelination after Injury.

Spinal cord injury (SCI) causes tissue structure damage and composition changes of the neural parenchyma, resulting in severe consequences for spinal cord function. Mimicking the components and microstructure of spinal cord tissues holds promise for restoring the regenerative microenvironment after SCI. Here, we have utilized electrospinning technology to develop aligned decellularized spinal cord fibers (A-DSCF) without requiring synthetic polymers or organic solvents. A-DSCF preserves multiple types of spinal cord extracellular matrix proteins and forms a parallel-oriented structure. Compared to aligned collagen fibers (A-CF), A-DSCF exhibits stronger mechanical properties, improved enzymatic stability, and superior functionality in the adhesion, proliferation, axonal extension, and myelination of differentiated neural progenitor cells (NPCs). Notably, axon extension or myelination has been primarily linked to Agrin (AGRN), Laminin (LN), or Collagen type IV (COL IV) proteins in A-DSCF. When transplanted into rats with complete SCI, A-DSCF loaded with NPCs improves the survival, maturation, axon regeneration, and motor function of the SCI rats. These findings highlight the potential of structurally and compositionally biomimetic scaffolds to promote axonal extension and remyelination after SCI.

Interactions between gold nanoparticles with different morphologies and human serum albumin.

Introduction: Three different shapes of gold nanoparticles were synthesized in this experiment. At the same time, studies compared their effects with human serum albumin (HSA). Methods: Gold nanoparticles (AuNPs) with three different morphologies, such as, nanospheres (AuNSs), nanorods (AuNRs), and nanoflowers (AuNFs) were synthesized via a seeding method and their characteristic absorption peaks were detected using ultraviolet-visible (UV-vis) absorption spectroscopy, Telectron microscopy (TEM), Dynamic Light Scattering (DLS) and Zeta potential measurements, circular dichroism (CD), and Fourier transform infrared spectroscopy (FTIR) to study the interactions between them and HSA. By comparing the thermodynamic parameters and quenching mechanism of the three materials, similarities and differences were determined in their interactions with HSA. Results: The results showed that with an increase in the concentration of the AuNPs with the three different morphologies, the UV-vis absorption peak intensity of the mixed solution increased, but its fluorescence intensity was quenched. This indicates that the three types of AuNPs interact with HSA, and that the interactions between them represent a static quenching process, which is consistent with the conclusions derived from three-dimensional fluorescence experiments. Through variable-temperature fluorescence experiments, the binding constants, number of binding sites, and thermodynamic parameters of the interactions between the three types of AuNPs and HSA were determined. The Gibbs free energy changes were <0, indicating that the reactions of the three types of AuNPs with HSA are spontaneous, resulting in associated matter. Binding constant measurements indicated that the strongest binding took place between the AuNFs and HSA. In addition, the results of fluorescence, CD spectroscopy, and FTIR showed that three different shapes of AuNPs can induce conformational changes in HSA and reduce the α-helix content. Among them, AuNFs have the smallest ability to induce conformational changes. Discussion: According to studies, AuNFs interact more favorably with HSA. This can be used as a reference for the administration of drugs containing AuNPs.

Impact renaming non-alcoholic fatty liver disease to metabolic associated fatty liver disease in prevalence, characteristics and risk factors.

BACKGROUND: Recently, a group of hepatologists proposed to rename non-alcoholic fatty liver disease (NAFLD) as metabolic associated fatty liver disease (MAFLD) with modified diagnostic criteria. It is important to note, however, that there are some differences between the diagnostic criteria used for NAFLD and MAFLD. Since the research on MAFLD is just beginning, however, evidence on its incidence and prevalence in the general population and in specific subpopulations remains limited. AIM: To assess epidemiology of fatty liver in new definition and compare MAFLD with NAFLD. Exploring risk factors of MAFLD individuals. METHODS: This was a retrospective, cross-sectional study. A total of 85242 adults were selected from the Chinese health management database in 2017-2022. The data of general information, laboratory indicators, lifestyle management and psychological status were obtained. MAFLD was diagnosed as ultrasound diagnosis of fatty liver and at least one between these three conditions: Overweight/obesity, type 2 diabetes mellitus (T2DM) or metabolic dysregulation. Metabolic factors were not considered in NAFLD diagnosis standard. The clinical characteristics of MAFLD and NAFLD were analysed using descriptive statistics. Continuous variables normally distributed were expressed as means ± SD. Categorical variables were expressed as frequencies and proportions. Binary logistic regression was used to determine risk factors of the MAFLD. RESULTS: The prevalence of MAFLD and NAFLD was 40.5% and 31.0%, respectively. The MAFLD or NAFLD population is more likely to be older (M: 47.19 ± 10.82 vs 43.43 ± 11.96; N: 47.72 ± 11.17 vs 43.71 ± 11.66), male (M: 77.21% vs 44.43%; N: 67.90% vs 53.12%) and high body mass index (M: 26.79 ± 2.69 vs 22.44 ± 2.48; N: 26.29 ± 2.84 vs 23.29 ± 3.12) than the non-MAFLD or non-MAFLD population. In multivariate analysis, general information (e.g., ≥ 2 metabolic abnormalities OR = 3.38, (95%CI: 2.99-3.81), P < 0.001; diastolic blood pressure OR = 1.01, (95%CI: 1.00-1.01), P = 0.002), laboratory results [e.g.,total bilirubin (TBIL) OR = 0.98, (95%CI: 0.98-0.99), P < 0.001; serum uric acid(SUA) OR = 1.01, (95%CI: 1.01-1.01), P < 0.001], and lifestyle factors [e.g., drink beverage OR = 0.32, (95%CI: 0.17-0.63), P = 0.001] were influence factors for MAFLD. Our study results offer new insight into potential risk factors associated with fatty liver disease, including SUA, TBIL and creatinine, all of which are related to chronic renal disease (CKD). CONCLUSION: MAFLD is more prevalent than NAFLD, with two-fifths of individuals meeting the diagnosis criteria. MAFLD and NAFLD populations have different clinical characteristics. CKD may be related with MAFLD.

Drug-coated balloons for treating de novo lesions in large coronary vessels: A case report.

BACKGROUND: Percutaneous transluminal coronary angioplasty, while an effective intervention, can frequently lead to acute occlusion with severe consequences. Although clinical trials have demonstrated the efficacy of drug-coated balloons (DCB) in treating acute coronary artery occlusion and in preventing restenosis, there has been limited exploration on the use of DCB in treating de novo lesions in large vessels. Currently, DCB are only recommended for patients with small vessel lesions and in-stent restenosis lesions, those at high risk of bleeding, and other special groups of patients. CASE SUMMARY: This report presents a case of successful drug-coated balloon treatment of de novo lesions in large coronary vessels. Postoperatively, the patient demonstrated favorable recovery, with subsequent examination results revealing no significant differences from the previous examination. CONCLUSION: The successful treatment of the patient in our case highlights the potential of DCB in the treatment of de novo lesions in large coronary vessels.

Single-cell analysis reveals region-heterogeneous responses in rhesus monkey spinal cord with complete injury.

Spinal cord injury (SCI) leads to severe sensory and motor dysfunction below the lesion. However, the cellular dynamic responses and heterogeneity across different regions below the lesion remain to be elusive. Here, we used single-cell transcriptomics to investigate the region-related cellular responses in female rhesus monkeys with complete thoracic SCI from acute to chronic phases. We found that distal lumbar tissue cells were severely impacted, leading to degenerative microenvironments characterized by disease-associated microglia and oligodendrocytes activation alongside increased inhibitory interneurons proportion following SCI. By implanting scaffold into the injury sites, we could improve the injury microenvironment through glial cells and fibroblast regulation while remodeling spared lumbar tissues via reduced inhibitory neurons proportion and improved phagocytosis and myelination. Our findings offer crucial pathological insights into the spared distal tissues and proximal tissues after SCI, emphasizing the importance of scaffold-based treatment approaches targeting heterogeneous microenvironments.
