Effectiveness and Influencing Factors of Home-Center-Based Cardiac Rehabilitation as a Transitional Strategy for Acute Myocardial Infarction Patients.

Currently, providing patients, particularly those with acute myocardial infarction (AMI), with comprehensive cardiac rehabilitation (CR) has been challenging because of the inadequate availability of medical resources in developing countries. To ensure balance between disease instability and early rehabilitation, strategies for facilitating professional and comprehensive CR opportunities for patients with AMI must be explored.A prospective cohort study was carried out on 1,533 patients with AMI who were admitted to a tertiary hospital between July 2018 and October 2019. Following the principle of voluntarism, 286 patients with AMI participated in home-center-based CR (HCB group), whereas 1,247 patients received usual care (UC group). The primary endpoint of this study was the occurrence of cardiovascular events at 30 months after AMI. Moreover, the study analyzed factors that influence participation rate and effectiveness of the CR model.After analysis, a significant difference in the occurrence of cardiovascular endpoints between the HCB group and the UC group was observed (harzard ratio, 0.68 [95%CI, 0.51-0.91], P = 0.008), with participation in home-center-based CR being an independent influencing factor. Multivariate regression analysis revealed age, gender, smoking history, triglyceride levels, and ejection fraction as independent factors that influence participation rate. Female gender, peak oxygen uptake per kilogram body weight, and ventilation/carbon dioxide production slope were identified as factors that affect the effectiveness of the CR model.In the context of developing countries, this study demonstrates that the home-center-based CR model is efficient and analyzes factors that influence participation rate and effectiveness of the model. These findings provide practical insights for further development of CR programs.

CoS1.097 nanocrystals as new nanoplatforms for photothermal therapy of arterial inflammation.

Cardiovascular diseases caused by atherosclerosis (AS) seriously damage human health. Nano-photothermal technology has been proven to inhibit the development of vascular inflammation by inhibiting the proliferation of inflammatory macrophages. However, photothermal therapy can inhibit the enrichment of AS macrophages in the early stage, but the inhibitory effect is insufficient in the later stage. Herein, we designed and prepared CoS1.097 nanocrystals by a simple hydrothermal method as new nanoplatforms for efficient photothermal therapy of arterial inflammation. CoS1.097 nanocrystals exhibited the degradability to release the cobalt ions, and can inhibit the proliferation of macrophages both in vitro and in vivo resulting from the slowly released cobalt ions. Moreover, CoS1.097 nanocrystals showed intense absorption in the NIR region, thus showing excellent photothermal performance. When irradiated by an 808 nm laser, the photothermal effect of CoS1.097 nanocrystals can more efficiently kill the macrophages which play an important role in the development of atherosclerosis. As far as we know, this is the first work on CoS1.097 nanocrystals for photothermal therapy of arterial inflammation.

Development and Validation of a Community-Based Prediction Model for Depression in Elderly Patients with Diabetes: A Cross-Sectional Study.

Background: In elderly diabetic patients, depression is often overlooked because professional evaluation requires psychiatrists, but such specialists are lacking in the community. Therefore, we aimed to create a simple depression screening model that allows earlier detection of depressive disorders in elderly diabetic patients by community health workers. Methods: The prediction model was developed in a primary cohort that consisted of 210 patients with diabetes, and data were gathered from December 2022 to February 2023. The independent validation cohort included 99 consecutive patients from February 2023 to March 2023. Multivariable logistic regression analysis was used to develop the predictive model. We incorporated common demographic characteristics, diabetes-specific factors, family structure characteristics, the self-perceived burden scale (SPBS) score, and the family APGAR (adaptation, partnership, growth, affection, resolution) score. The performance of the nomogram was assessed with respect to its calibration (calibration curve, the Hosmer-Lemeshow test), discrimination (the area under the curve (AUC)), and clinical usefulness (Decision curve analysis (DCA)). Results: The prediction nomogram incorporated 5 crucial factors such as glucose monitoring status, exercise status, monthly income, sleep disorder status, and the SPBS score. The model demonstrated strong discrimination in the primary cohort, with an AUC of 0.839 (95% CI, 0.781-0.897). This discriminative ability was further validated in the validation cohort, with an AUC of 0.857 (95% CI, 0.779-0.935). Moreover, the nomogram exhibited satisfactory calibration. DCA suggested that the prediction of depression in elderly patients with diabetes mellitus was of great clinical value. Conclusion: The prediction model provides precise and user-friendly guidance for community health workers in preliminary screenings for depression among elderly patients with diabetes.

Exploring seasonal variations, assembly dynamics, and relationships of bacterial communities in different habitats of marine ranching.

Offshore coastal marine ranching ecosystems provide habitat for diverse and active bacterial communities. In this study, 16S rRNA gene sequencing and multiple bioinformatics methods were applied to investigate assembly dynamics and relationships in different habitats. The higher number of edges in the water network, more balanced ratio of positive and negative links, and more keystone species included in the co-occurrence network of water. Stochastic processes dominated in shaping gut and sediment community assembly (R2 < 0.5), while water bacterial community assembly were dominated by deterministic processes (R2 > 0.5). Dissimilarity-overlap curve model indicated that the communities in different habitats have general dynamics and interspecific interaction (P < 0.001). Bacterial source-tracking analysis revealed that the gut was more similar to the sediment than the water bacterial communities. In summary, this study provides basic data for the ecological study of marine ranching through the study of bacterial community dynamics.

Visulization of peroxynitrite variation for accurate diagnosis and assessing treatment response of hepatic fibrosis using a Golgi-targetable ratiometric fluorescent probe.

Hepatic fibrosis (HF) is caused by persistent inflammation, which is closely associated with hepatic oxidative stress. Peroxynitrite (ONOO-) is significantly elevated in HF, which would be regarded as a potential biomarker for the diagnosis of HF. Research has shown that ONOO- in the Golgi apparatus can be overproduced in HF, and it can induce hepatocyte injury by triggering Golgi oxidative stress. Meanwhile, the ONOO- inhibitors could effectively relieve HF by inhibiting Golgi ONOO-, but as yet, no Golgi-targetable fluorescent probe available for diagnosis and assessing treatment response of HF through sensing Golgi ONOO-. To this end, we reported a ratiometric fluorescent probe, Golgi-PER, for diagnosis and assessing treatment response of HF through monitoring the Golgi ONOO-. Golgi-PER displayed satisfactory sensitivity, low detection limit, and exceptional selectivity to ONOO-. Combined with excellent biocompatibility and good Golgi-targeting ability, Golgi-PER was further used for ratiometric monitoring the Golgi ONOO- fluctuations and screening of ONOO- inhibitors from polyphenols in living cells. Meanwhile, using Golgi-PER as a probe, the overexpression of Golgi ONOO- in HF and the treatment response of HF to the screened rosmarinic acid were precisely visualized for the first time. Furthermore, the screened RosA has a remarkable therapeutic effect on HF, which may be a new strategy for HF treatment. These results demonstrated the practicability of Golgi-PER for monitoring the occurrence, development, and personalized treatment response of HF.

Intubation at Birth Is Associated with Death after Pulmonary Hemorrhage in Very Low Birth Weight Infants.

OBJECTIVE: This retrospective cohort study was performed to clarify the association between intubation in the delivery room and the mortality after pulmonary hemorrhage in very low birth weight infants (VLBWIs) during hospitalization. METHODS: The study participants were screened from the VLBWIs admitted to the neonatal intensive care unit (NICU) of the Children's Hospital Affiliated to Nanjing Medical University from 31 July 2019 to 31 July 2022. The newborns who ultimately were included were those infants who survived until pulmonary hemorrhage was diagnosed. These subjects were divided into the intubation-at-birth group (n = 29) and the non-intubation-at-birth group (n = 35), retrospectively. RESULTS: Univariate analysis found that the intubation group had a higher mortality and shorter hospital stay than the non-intubation group (p < 0.05) (for mortality: 25/29 (86.21%) in intubation group versus 14/35 (40.00%) in non-intubation group). By multivariate analysis, the result further showed that intubation in the delivery room was related to shorter survival time and higher risk of death (adjusted hazard ratio: 2.341, 95% confidence interval: 1.094-5.009). CONCLUSIONS: Intubation at birth suggested a higher mortality in the VLBWIs when pulmonary hemorrhage occurred in the NICU.

Risk factors of acute ischemic stroke and the role of angiotensin I in predicting prognosis of patients undergoing endovascular thrombectomy.

Purpose: The interaction between the renin-angiotensin system (RAS) and the acute ischemic stroke (AIS) is definite but not fully understood. This study aimed to analyze the risk factors of AIS and explore the role of serum indicators such as angiotensin I (Ang I) in the prognosis of patients undergoing endovascular thrombectomy (EVT). Patients and methods: Patients with AIS who underwent EVT and healthy controls were retrospectively enrolled in this study, and the patients were divided into a good or a poor prognosis group. We compared Ang I, blood routine indexes, biochemical indexes, electrolyte indexes, and coagulation indexes between patients and controls. We used univariate and multivariate logistic regression analyses to evaluate possible risk factors for AIS and the prognosis of patients undergoing EVT. Independent risk factors for the prognosis of patients undergoing EVT were identified through multifactorial logistic regression analyses to construct diagnostic nomograms, further assessed by receiver operating characteristic curves (ROC). Results: Consistent with previous studies, advanced age, high blood glucose, high D-dimer, and high prothrombin activity are risk factors for AIS. In addition, Ang I levels are lower in AIS compared to the controls. The level of Ang I was higher in the good prognosis group. Furthermore, we developed a nomogram to evaluate its ability to predict the prognosis of AIS after EVT. The AUC value of the combined ROC model (Ang I and albumin-globulin ratio (AGR)) was 0.859. Conclusions: In conclusion, advanced age, high blood glucose, high D-dimer, and high prothrombin activity are risk factors for AIS. The combined Ang I and AGR model has a good predictive ability for the prognosis of AIS patients undergoing arterial thrombectomy.

Transcriptomic and genomic characteristics of intrahepatic metastases of primary liver cancer.

BACKGROUND: Patients with primary multifocal hepatocellular carcinoma (HCC) have a poor prognosis and often experience a high rate of treatment failure. Multifocal HCC is mainly caused by intrahepatic metastasis (IM), and though portal vein tumor thrombosis (PVTT) is considered a hallmark of IM, the molecular mechanism by which primary HCC cells invade the portal veins remains unclear. Therefore, it is necessary to recognize the early signs of metastasis of HCC to arrange better treatment for patients. RESULTS: To determine the differential molecular features between primary HCC with and without phenotype of metastasis, we used the CIBERSORTx software to deconvolute cell types from bulk RNA-Seq based on a single-cell transcriptomic dataset. According to the relative abundance of tumorigenic and metastatic hepatoma cells, VEGFA+ macrophages, effector memory T cells, and natural killer cells, HCC samples were divided into five groups: Pro-T, Mix, Pro-Meta, NKC, and MemT, and the transcriptomic and genomic features of the first three groups were analyzed. We found that the Pro-T group appeared to retain native hepatic metabolic activity, whereas the Pro-Meta group underwent dedifferentiation. Genes highly expressed in the group Pro-Meta often signify a worse outcome. CONCLUSIONS: The HCC cohort can be well-typed and prognosis predicted according to tumor microenvironment components. Primary hepatocellular carcinoma may have obtained corresponding molecular features before metastasis occurred.

Cisplatin-based miRNA delivery strategy inspired by the circCPNE1/miR-330-3p pathway for oral squamous cell carcinoma.

Circular RNAs (circRNAs) are ideal biomarkers of oral squamous cell carcinoma (OSCC) because of their highly stable closed-loop structure, and they can act as microRNA (miRNA) sponges to regulate OSCC progression. By analyzing clinical samples, we identified circCPNE1, a dysregulated circRNA in OSCC, and its expression level was negatively correlated with the clinical stage of OSCC patients. Gain-of-function assays revealed the tumor-suppressive effect of circCPNE1, which was then identified as a miR-330-3p sponge. MiR-330-3p was recognized as a tumor promoter in multiple studies, consistent with our finding that it could promote the proliferation, migration, and invasion of OSCC cells. These results indicated that selective inhibition of miR-330-3p could be an effective strategy to inhibit OSCC progression. Therefore, we designed cationic polylysine-cisplatin prodrugs to deliver antagomiR-330-3p (a miRNA inhibitory analog) via electrostatic interactions to form PP@miR nanoparticles (NPs). Paratumoral administration results revealed that PP@miR NPs effectively inhibited subcutaneous tumor progression and achieved partial tumor elimination (2/5), which confirmed the critical role of miR-330-3p in OSCC development. These findings provide a new perspective for the development of OSCC treatments.

Chronic ultraviolet irradiation induces memory deficits via dysregulation of the dopamine pathway.

The effects of ultraviolet (UV) radiation on brain function have previously been investigated; however, the specific neurotransmitter-mediated mechanisms responsible for UV radiation-induced neurobehavioral changes remain elusive. In this study, we aimed to explore the mechanisms underlying UV radiation-induced neurobehavioral changes. In a mouse model, we observed that UV irradiation of the skin induces deficits in hippocampal memory, synaptic plasticity, and adult neurogenesis, as well as increased dopamine levels in the skin, adrenal glands, and brain. Chronic UV exposure altered the expression of genes involved in dopaminergic neuron differentiation. Furthermore, chronic peripheral dopamine treatments resulted in memory deficits. Systemic administration of a dopamine D1/D5 receptor antagonist reversed changes in memory, synaptic plasticity, adult neurogenesis, and gene expression in UV-irradiated mice. Our findings provide converging evidence that chronic UV exposure alters dopamine levels in the central nervous system and peripheral organs, including the skin, which may underlie the observed neurobehavioral shifts, such as hippocampal memory deficits and impaired neurogenesis. This study underscores the importance of protection from UV exposure and introduces the potential of pharmacological approaches targeting dopamine receptors to counteract the adverse neurological impacts of UV exposure.

Network pharmacology analysis and molecular docking using the Chinese herbal agent WYHX formula (according to Yan Dexin): Management of coronary artery disease.

BACKGROUND: The therapeutic impact of the Wenyang Huoxue (WYXH) formula on coronary atherosclerotic heart disease (CHD) is well established, yet the precise mechanisms are currently not fully understood. This study provides preliminary insights into the potential mechanisms underlying the therapeutic effects of the formula on CHD by utilizing network pharmacology and molecular docking technology. MATERIALS AND METHODS: The primary active constituents and their corresponding action targets for the formula were retrieved from the TCMSP database. Utilizing Cytoscape 3.9.1 software, a network linking the components of the formula to their respective targets was constructed. Information was collected from Genecards, OMIM, TTD, and DrugBank databases to identify targets related to CHD. The common targets shared by the formula and CHD were then imported into the STRING database to create a protein-protein interaction (PPI) network. Following this, enrichment analyses were performed on the shared targets using Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Finally, molecular docking was conducted on the primary active compounds and the core targets. RESULTS: The network encompassing the components and targets of the formula comprises a total of 311 nodes and 895 edges. Compounds exhibiting higher degree centrality consist of quercetin, ß-sitosterol, and kaempferol. In the PPI network, proteins with elevated degree centrality are protein kinase B (AKT1), epidermal growth factor receptor (EGFR), and mitogen-activated protein kinase 3 (MAPK3). The results of GO and KEGG enrichment analyses reveal that the biological processes associated with the efficacy of the formula in treating CHD primarily involve positive regulation of gene expression, hypoxia response, and lipopolysaccharide response, among others. The signaling pathways primarily involved include phosphatidylinositol 3-kinase and protein kinase B (PI3K-AKT), MAPK3, tumor necrosis factor (TNF), and so on. Molecular docking results demonstrate a strong affinity between quercetin, ß-sitosterol, and kaempferol with AKT1, EGFR, and MAPK3. CONCLUSION: We showed for the first time that AKT1, EGFR, and MAPK3 are potential targets influenced by the WYHX formula in CHD treatment. The therapeutic effects could possibly involve signaling pathways such as the PI3K-AKT, MAPK, TNF, and AGE-RAGE pathways.

Quality changes of whitespotted conger (Conger myriaster) based physicochemical changes and label-free proteomics analysis during frozen storage.

Whitespotted conger (Conger myriaster) muscle proteins were susceptible to oxidative denaturation during frozen storage. The objective of this study was to investigate the alterations in quality through physicochemical analysis and proteomics after whitespotted conger stored at temperatures of -18 °C and -60 °C. The microstructural observation revealed the noticeable variations such as increased interstitial space and fractured muscle fibre with extension of frozen storage time, and the muscle fibre of whitespotted conger stored at -60 °C were more intact than those stored at -18 °C. The raised TVB-N value indicated that the freshness of whitespotted conger decreased during 120-day frozen storage period. Analysis of myofibrillar protein content and SDS-PAGE demonstrated that compared to -18 °C, lower storage temperature (-60 °C) could better maintain the structure of whitespotted conger muscle by inhibiting protein degradation and oxidation. To reveal the mechanism of protein degradation, label-free quantitative proteomic analysis was performed through LC-MS/MS. The structural proteins including domain-associated proteins and actin-related proteins were up-regulated during frozen storage, but the phosphoglycerate kinase, phosphoglycerate mutase, and fructose-bisphosphate aldolase were down-regulated. Storage at -18 °C accelerated the up- or down-regulation of those differentially abundant proteins. According to KEGG analysis, up- or down-regulated pathways such as glycolysis/gluconeogenesis, carbon metabolism, biosynthesis of amino acids, and calcium signalling pathway mainly accounted for the protein degradation and quality reduction of whitespotted conger at low temperature. These results provided a theoretical basis for improving the quality stability of whitespotted conger during frozen storage.

Clinical efficacy of high-voltage pulsed radiofrequency combined with stellate ganglion block in the acute phase of thoracic and dorsal herpes zoster neuralgia under dual guidance of ultrasound and C-arm.

OBJECTIVES: A single therapeutic approach is not always successful in the treatment of herpes zoster neuralgia, and the appropriate combination of different treatments deserves further exploration. In this study, we investigated the clinical efficacy of high-voltage long-duration pulsed radiofrequency (PRF) combined with stellate ganglion block (SGB) in the acute phase of thoracic and dorsal herpes zoster neuralgia under dual guidance of ultrasound and C-arm. METHODS: 79 cases of acute zoster neuralgia were grouped premised upon differing therapeutic approaches: standard voltage PRF (group S, the temperature, duration, pulse width, frequency and voltage were set to 42 °C, 300 s, 20 ms, 2 Hz, and 45 V), high-voltage long-duration PRF (group H, parameters of PRF were set to 42 °C, 900 s, 20 ms, 2 Hz, and 90 V, respectively), and high-voltage long-duration PRF combined with SGB (group C, parameter settings for PRF are the same as those for group H). The therapeutic outcomes were assessed utilizing the numeric rating scale (NRS), Pittsburgh sleep quality index (PSQI), and Hamilton anxiety rating scale (HAMA). The incidence of clinically significant postherpetic neuralgia post-treatment had been documented. RESULTS: Compared to baseline, scores of NRS, PSQI, and HAMA at each time point post-treatment decreased across all groups, and the decrease was more significant in the C group than in the S group. At the later stage of treatment, the consumption of pregabalin and tramadol and the plasma levels of interleukin-6 and galectin-3 in the C group were significantly lower than those in the S group. The incidence of PHN in the C group was significantly lower than in the S group. CONCLUSIONS: The combination of high-voltage long-duration PRF combined with SGB under dual guidance of ultrasound and C-arm represents a safe, effective, environmentally friendly, and cost-efficient method for treating AZN, significantly improving sleep quality, alleviating anxiety, and reducing the risk of PHN occurrence.

Novel insights into the mechanism of dynamic changes in microstructure and physicochemical properties of corn straw pretreated by ball milling and feasibility analysis of anaerobic digestion.

In this study, the effects of Ball milling (BM) pretreatment (0-240 min) on the microstructure, physicochemical properties and subsequent methanogenesis performance of corn straw (CS) were explored, and the feasibility analysis was carried out. The results showed that BM pretreatment destroyed the dense structure of the CS, and the particle size was significantly reduced (D50: 13.85 µm), transforming it into a cell-scale granular form. The number of mesopores increased, the pore volume (PV) (0.032 cm3/g) and specific surface area (SSA) (4.738 m2/g) considerably increased, and the water-absorbent property was improved. The crystalline order of cellulose was disrupted and the crystallinity (CrI) (8.61 %) and crystal size (CrS) (3.37) were remarkably reduced. The cross-links between lignocelluloses were broken, and the relative content and functional groups did not alter obviously. The bulk density (BD), repose angle (RA) and slip angle (SA) dramatically increased. As a result, CS was more readily accessible, attached and utilized by microorganisms and enzymes, causing the hydrolysis and acidification of AD to be greatly facilitated. Compared with the untreated group, the cumulative methane production (CMP) increased by 35.83 %-101.97 %, and the lag phase time (λ) was shortened by 33.04 %-71.17 %. The results of redundancy analysis, Pearson analysis and Mantel test showed that BM pretreatment affects the process of AD by changing the physicochemical factors of CS. The normalization analysis showed that particle size (D90) and BD can be used as direct indicators to evaluate the performance of AD and predict the threshold of biodegradation of CS. Energy analysis and energy conversion assessment showed that BM is a green and efficient AD pretreatment strategy. This result provides a theoretical basis for the industrial application of BM pretreatment towards more energy-efficient and sustainable development.

The decision-making process of palliative care among male caregivers of chronically ill patients-A grounded theory study.

BACKGROUND: Family caregivers have a vital role to play in palliative care for chronically ill patients. In Taiwan, caregiver demographics are evolving, with the number of male caregivers increasing. Gender differences influence psychosocial behaviours, thought processes and communication styles. In healthcare, acknowledgement of gender differences facilitates effective delivery of high-quality care. AIM: The aim of this study is to explore male caregivers' decision-making process for palliative care for chronically ill family members. METHODS: This study employed grounded theory to generate a substantive theory of male caregivers' decision-making process for palliative care for chronically ill family members. We recruited 22 male participants from three inner-city teaching hospitals in Taiwan. FINDINGS: Regarding the decision-making process of palliative care of chronic ill family, where male caregivers do not want their loved ones suffering anymore, the male caregivers' decision-making process was impacted, first, by caregivers' views on the last stage of life; second, by their wish for good care during the end of life; and third, by their conviction that the patients' wishes should be respected. Furthermore, caregivers' philosophy of life and death is also a supportive ground for decision-making. This philosophy was influenced by their education in palliative care, financial status and religious beliefs and practices. The core category emerging from this study is encapsulated by a participant's assertion, 'How difficult is it? There are no male and female differences'. CONCLUSION: We found that palliative care experiences of male caregivers are important for the decision-making process for palliative care for their chronically ill family members. Caregivers want their loved ones to receive good care as the last step in life, to respect their wishes and no more suffering for the patient. Therefore, health professionals should be familiar with the palliative care process that caregivers go through to offer updated information when needed.

Fasting-mimicking diet remodels gut microbiota and suppresses colorectal cancer progression.

The progression of colorectal cancer is closely associated with diet. Fasting-mimicking diet (FMD) is a promising type of dietary intervention that have beneficial effects in the prevention and treatment of various cancers. We investigated the therapeutic effect of 4-day FMD against colorectal cancer in mice through immune cell analysis, microbiota composition analysis and anti-PD-1 treatment. These FMD cycles effectively suppressed colorectal cancer growth, reduced cell proliferation and angiogenesis, increased tumor-infiltration lymphocytes especially CD8+T cells. FMD stimulated protective gut microbiota, especially Lactobacillus. Supplementation of Lactobacillus johnsonii induced similar results as FMD intervention, which also suppressed tumor growth and increased CD45+ and CD8+ T cells. Additionally, FMD synthesizing with anti-PD-1 therapy effectively inhibited CRC progression. These findings suggest that Lactobacillus. johnsonii is necessary for the anticancer process of FMD in CRC. FMD through its effects on both gut microbiota and immune system, effectively suppressed colorectal cancer progression in mouse model.

Unusual Janus Bi2TeSe2 Topological Insulators Displaying Second-Harmonic Generation, Linear-in-Temperature Resistivity, and Weak Antilocalization.

Well-established knowledge about inversion-symmetric Bi2TexSe3-x topological insulators characterizes the promising new-generation quantum device. Noticeably, the inversion asymmetric phase containing different surface electronic structures may create an extra topological phenomenon pointing to a new device paradigm. Herein, Janus Bi2TeSe2 single-crystal nanosheets with an unconventional stacking sequence of Se-Bi-Se-Bi-Te are realized via chemical vapor deposition growth, which is clarified by atomically resolved AC-STEM and elemental mapping. An obvious polarization-dependent second-harmonic generation with a representative 6-fold rotational symmetry is detected due to the broken out-of-plane mirror symmetry in this system. Low-temperature transport measurements display a strange metal-like linear-in-temperature resistivity. Anomalous conductance peaks under low magnetic fields induced by the weak antilocalization effect of topological surface states and the two-dimensional transport-dominated anisotropic magnetoresistance are revealed. These findings correlate the Janus Bi2TeSe2 phase with emerging physics topics, which would inspire fresh thoughts in well-developed Bi3TexSe3-x topological insulators and open up opportunities for exploring hybrid nonlinear optoelectronic topological devices.

OCIAD2 promotes pancreatic cancer progression through the AKT signaling pathway.

BACKGROUND: OCIAD2（Ovarian carcinoma immunoreactive antigen-like protein 2） is a protein reported in various cancers. However, the role of OCIAD2 has not been explored in pan-cancer datasets. The purpose of this research lies in analyzing the expression level and prognostic-related value of OCIAD2 in different human cancers, as well as revealing the underlying mechanism in specific cancer type (pancreatic adenocarcinoma, PAAD). METHODS: The correlation between OCIAD2 expression level and clinical relevance in different human cancers was investigated from bioinformatical perspective (GTEx and TCGA). The OCIAD2 expression level and clinical significance in PAAD were explored in GEO datasets and tissue microarray. Functional experiments were used to determine the OCIAD2 cell functions in vitro and in vivo. GSEA, western blot and immunohistochemistry were used to uncover the potential mechanism. RESULTS: OCIAD2 expression level was closely correlated with clinical relevance in many cancer types through pan-cancer analysis, and we found OCIAD2 was highly expressed in PAAD and associated with poorer prognosis. OCIAD2 acted as the promotor of Warburg effect and influenced PAAD cells proliferation, migration and apoptosis. Mechanistically, OCIAD2 upregulation may boost glycolysis in PAAD via activating the AKT signaling pathway in PAAD. CONCLUSIONS: In PAAD, OCIAD2 promotes Warburg effect via AKT signaling pathway and targeting cancer cells metabolic reprogramming could be a potential treatment.

Nanosilicate-reinforced GelMA-PEGDA hydrogel promotes angiogenesis for bone regeneration.

Bone tissue engineering has emerged as a pivotal field addressing the critical clinical needs of bone fractures. This study focused on developing multi-composite hydrogels by synergizing biocompatible GelMA macromolecules with synthetic PEGDA and reinforcing them with nanosilicates (SN). The incorporation of SN introduces crucial trace elements such as silicon, magnesium, and lithium, promoting both angiogenesis and osteogenesis. Characterizations revealed that PEGDA significantly reinforced the composite hydrogels' stability, while SN further enhanced the mechanical integrity of the GelMA-PEGDA-SN (GPS) hydrogels. Cell studies designated that GPS improved cell proliferation and migration, angiogenic VEGF/eNOS expression and osteogenic differentiation. In vivo experiments showed that GPS hydrogels effectively enhanced calvarial bone healing, with the GPS-2 formulation (2 % SN) displaying superior bone coverage and increased vascular formation. Assessments of osteogenic formation and the angiogenic marker CD31 validated the comprehensive bone regeneration potential of GPS hydrogels. These findings highlight the significant promise of GPS hydrogels in fostering bone healing with promoted angiogenesis.
