Chromosome-level genome assembly and population genomic analysis provide insights into the genetic diversity and adaption of Schizopygopsis younghusbandi on the Tibetan Plateau.

The Yarlung Tsangpo River on the Tibetan Plateau provides a unique natural environment for studying fish evolution and ecology. However, the genomes and genetic diversity of plateau fish species have been rarely reported. Schizopygopsis younghusbandi, a highly specialized Schizothoracine species and economically important fish inhabiting the Yarlung Tsangpo River, is threatened by overfishing and biological invasion. Herein, we generated a chromosome-level genome of S. younghusbandi and whole-genome resequencing data for 59 individuals from six locations of the river. The results showed that the divergence time between S. younghusbandi and other primitive Schizothoracine species was ∼4.2 Mya, coinciding with the major phase of the Neogene Tibetan uplift. The expanded gene families enriched in DNA integration and replication, ion binding and transport, energy storage, and metabolism likely contribute to the adaption of this species. The S. younghusbandi may have diverged from other highly specialized Schizothoracine species in the Zanda basin during the Pliocene epoch, which underwent major population reduction possibly due to the drastic climate change during the last glacial period. Population analysis indicated that the ancient population might have originated upstream before gradually adapting to evolve into the populations inhabiting the mid-stream and downstream regions of the Yarlung Tsangpo River. In conclusion, the chromosome-level genome and population diversity of S. younghusbandi provide valuable genetic resources for the evolution, ecology, and conservation studies of endemic fishes on the Tibetan Plateau.

Do human resource systems indeed have "system" effects? The dual internal fit model of a high-performance work system.

The configurational or "internal fit" perspective proposes that human resource (HR) systems are most effective when individual practices are configured such that they fit together and are mutually reinforcing. The Ability-Motivation-Opportunity (AMO) model has emerged as a predominant way to select and configure HR practices based on whether they attempt to enhance employee ability, motivation, or opportunities. Despite the widespread use of the configurational perspective and AMO model in building a high-performance work system (HPWS), researchers have not clearly articulated how HR practices across the AMO domains should be configured to maximize internal fit across the system. Moreover, research has overlooked the hierarchical nature of an HPWS, such that HR practices are nested within a particular AMO domain, and the AMO domains, in turn, are nested within the HPWS. To address these gaps, we develop and test a dual internal fit model that specifies synergistic interactions within and among AMO domains. Analyses of six-wave panel data from 640 firms reveal that internal fit effects of HR practices simultaneously exist within (i.e., HR practice-level interactions) and among AMO domains (i.e., AMO domain-level interactions) to predict workforce productivity and ultimately firm profitability. Moreover, the two sets of interactions predict outcomes beyond the additive effects of the HR practices on which prior research has typically focused. These findings show that HR practices can be configured to have "system" effects. They also highlight the value of the dual internal fit model to understand the performance benefits of optimally configured HR systems. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Relationship between stress hyperglycemia ratio and prognosis in patients with aneurysmal subarachnoid hemorrhage: a two-center retrospective study.

Previous research have demonstrated that the stress hyperglycemia ratio (SHR) accurately reflects acute hyperglycemic states and correlates with adverse outcomes. This study aims to explore the relationship between SHR and the prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH). Patients with aSAH were categorized into four groups based on SHR tertiles. Functional outcomes were evaluated at 12 months using the modified Rankin Scale (mRS), with scores ranging from 0 to 2 indicating a good outcome and 3-6 indicating a poor outcome. The associations between SHR and functional outcomes were analyzed using logistic regression models and restricted cubic spline analysis. A total of 127 patients exhibited poor functional outcomes. Following comprehensive adjustments, those in the highest SHR tertile had a significantly increased risk of poor prognosis compared to those in the lowest tertile (odds ratio [OR], 4.12; 95% confidence interval [CI]: 1.87-9.06). Moreover, each unit increase in SHR was associated with a 7.51-fold increase in the risk of poor prognosis (OR, 7.51; 95% CI: 3.19-17.70). Further analysis using restricted cubic spline confirmed a linear correlation between SHR and poor prognosis (P for nonlinearity = 0.609). Similar patterns were observed across all studied subgroups. Elevated SHR significantly correlates with poor functional prognosis at one year in patients with aSAH, independent of their diabetes status.

Modular and Regioselective Synthesis of Benzo-Fused Five-Membered Rings Enabled by Co/Ti Synergism.

The regiocontrol in constructing benzo-fused five-membered rings by C-H cyclization remains an important challenge. We report a highly general and regioselective methodology to access such heterocycles and indenones, where under the catalysis of CoBr2/bipyridine, aryl titanates, alkynes and EX2 (E = NR, S(O), RP(O), R2Si, CO, etc.) were assembled to various heterocycles and indenones in a modular manner. Unprecedented 1,2-Co/Ti heterobimetallic arylene and benzotitanole intermediates have played crucial roles in these syntheses.

ALBI Grade Is Associated with Clinical Outcomes of Critically Ill Patients with AKI: A Cohort Study with Cox Regression and Propensity Score Matching.

Background: The albumin-bilirubin (ALBI) grade has surfaced as a viable substitute for assessing liver functional reserve in individuals afflicted with hepatocellular carcinoma (HCC). ALBI grade also demonstrates the capacity to stratify distinct patient subcohorts bearing disparate prognostic implications in not only HCC but also other inflammatory diseases like acute pancreatitis. However, the association between ALBI grade and clinical outcomes of acute kidney injury (AKI) remains mysterious. Methods: The dataset was sourced from the Multiparameter Intelligent Monitoring in Intensive Care Database IV (MIMIC-IV) version 2.0. ALBI grade was calculated in a nomogram utilizing albumin and bilirubin. In order to ascertain the connection between ALBI grades and clinical outcomes of patients with AKI, Cox proportional hazards regression analysis was employed with in-hospital, 30- and 90-day mortality as end points, respectively. The Kaplan-Meier (K-M) curve was employed to gauge the cumulative incidence of mortality based on various ALBI grades. To explore potential nonlinear relationships, the Restricted Cubic Spline (RCS) approach was adopted. Furthermore, a subgroup analysis was conducted to validate the durability of the correlation between ALBI grade and in-hospital mortality. Furthermore, equilibrium of confounding variables was also achieved through the application of propensity score matching (PSM). Results: The study encompassed a total of 12,518 patients (ALBI grade 1 : 2878, grade 2 : 6708, and grade 3 : 2932). Patients with heightened ALBI grades displayed a significant correlation with increased mortality in both univariate and various multivariate Cox regression models. RCS depicted a predominantly linear relationship. The robustness of the correlation was also affirmed across multifarious subpopulations through subgroup analysis. The association still remains after PSM. Conclusion: Elevated ALBI grade was associated with worse clinical outcomes of critically ill patients with AKI.

Silk fibroin biohydrogel composites for loading and ordered release of multiple active ingredients with enhanced bioactivity.

Bioactive hydrogels are currently receiving significant attention. In this study, silk fibroin tyramine-modified gelatin hydrogels (SF-TG) with varying degrees of tyramine root substitution were explored. The physicochemical property and biocompatibility of low degree of substitution tyramine-modified gelatin hydrogel (SF-LTG) and high degree of substitution tyramine-modified gelatin hydrogel (SF-HTG) were compared. The results showed that SF-LTG possessed better mechanical property and higher biocompatibility. Thus, SF-LTG was selected as a bioactive matrix and loaded with basic fibroblast growth factor (bFGF); subsequently, curcumin-coupled chitosan rods (CCCRs-EGF) enriched with epidermal growth factor (EGF) were added to obtain SF-LTG-bFGF@CCCRs-EGF hydrogels. The results showed that SF-LTG-bFGF@CCCRs-EGF retained the basic structural and mechanical properties of the SF-LTG matrix gel material and underwent multiple loading and orderly release with different activities while displaying antioxidant, anti-inflammatory, antimicrobial, and pro-cellular proliferation activities and orderly regulation of activity during wound healing. Therefore, the SF-LTG-bFGF@CCCRs-EGF hydrogel is of great value in healing complex wounds.

OBJECTIVE: This study aimed to analyze and explore the nursing effects of integrated medical and nursing care intervention in correction surgery for children with concealed penis. METHODS: A total of 76 eligible patients with concealed penis were randomly divided into an observation group and a control group. The control group received conventional nursing care, while the observation group received integrated medical and nursing care intervention. Outcomes include pain levels, comfort status, incidence of complications, and nursing satisfaction were collected and analyzed to investigate the nursing effects of the integrated medical and nursing care model. RESULTS: After 2/3 days of nursing intervention, the patients in the observation group had significantly lower pain scores (measured by FPS-R) compared to the control group (P < 0.05). The patients in the observation group also had significantly higher comfort scores (measured by Kolcabal) compared to the control group (P < 0.05). The incidence of complications in the observation group was significantly lower than that in the control group (2.63 vs. 23.68, P < 0.05). Parental satisfaction in the observation group was significantly higher than that in the control group (P < 0.05). CONCLUSION: The integrated medical and nursing care intervention in correction surgery for children with concealed penis demonstrated positive nursing effects. It effectively reduced pain, improved comfort, lowered the risk of complications, and increased parental satisfaction. This approach maximizes the role of nursing care and is recommended for clinical implementation.

Time-Optimal Trajectory Planning and Tracking for Autonomous Vehicles.

This article presents a hierarchical control framework for autonomous vehicle trajectory planning and tracking, addressing the challenge of accurately following high-speed, at-limit maneuvers. The proposed time-optimal trajectory planning and tracking (TOTPT) framework utilizes a hierarchical control structure, with an offline trajectory optimization (TRO) module and an online nonlinear model predictive control (NMPC) module. The TRO layer generates minimum-lap-time trajectories using a direct collocation method, which optimizes the vehicle's path, velocity, and control inputs to achieve the fastest possible lap time, while respecting the vehicle dynamics and track constraints. The NMPC layer is responsible for precisely tracking the reference trajectories generated by the TRO in real time. The NMPC also incorporates a preview algorithm that utilizes the predicted future travel distance to estimate the optimal reference speed and curvature for the next time step, thereby improving the overall tracking performance. Simulation results on the Catalunya circuit demonstrated the framework's capability to accurately follow the time-optimal raceline at an average speed of 116 km/h, with a maximum lateral error of 0.32 m. The NMPC module uses an acados solver with a real-time iteration (RTI) scheme, to achieve a millisecond-level computation time, making it possible to implement it in real time in autonomous vehicles.

Bioinformatics analysis and experimental verification of the cancer-promoting effect of DHODH in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is a malignant tumor of the urinary system. To explore the potential mechanisms of DHODH in ccRCC, we analyzed its molecular characteristics using public databases. TCGA pan-cancer dataset was used to analyze DHODH expression in different cancer types and TCGA ccRCC dataset was used to assess differential expression, prognosis correlation, immune infiltration, single-gene, and functional enrichment due to DHODH. The GSCALite and CellMiner databases were employed to explore drugs and perform molecular docking analysis with DHODH. Protein-protein interaction networks and ceRNA regulatory networks of DHODH were constructed using multiple databases. The effect of DHODH on ccRCC was confirmed in vitro. DHODH was highly expressed in ccRCC. Immune infiltration analysis revealed that DHODH may be involved in regulating the infiltration of immunosuppressive cells such as Tregs. Notably, DHODH influenced ccRCC progression by forming regulatory networks with molecules, such as hsa-miR-26b-5p and UMPS and significantly enhanced the malignant characteristics of ccRCC cells. Several drugs, such as lapatinib, silmitasertib, itraconazole, and dasatinib, were sensitive to DHODH expression and exhibited strong molecular binding with it. Thus, DHODH may promote ccRCC progression and is a candidate effective therapeutic target for ccRCC.

Fabrication of Mildew-Resistant Wood with Multi-Functional Properties Based on In Situ Growth of Metal-Organic Frameworks.

Wood is easily affected by decay fungi, mildew fungi, insects, water, UV, and other factors when used outdoors. In particular, mildew on the surface of wood negatively affects the appearance and practical use of wood or wood-based engineered products. In recent years, as a class of popular crystalline materials, metal-organic frameworks (MOFs) have been widely applied in electrochemistry, adsorption, anti-mildew efforts, and other areas. In this study, we first grew a Co-based metal-organic framework (Co-MOF) in situ on a wood surface and subsequently converted the Co-MOF in situ into a cobalt-nickel double hydroxide layer, which formed micro- and nanohierarchical composite structures on the wood surface. The low surface energy of the CoNi-DH@wood was further modified via impregnation with sodium laurate to obtain the superhydrophobic wood (CoNi-DH-La@wood). We characterized the microstructure, chemical composition, water contact angle, and anti-mold properties of the CoNi-DH-La@wood using SEM, XRD, XPS, water contact angle tests, and anti-fungal tests. The SEM, XRD, and XPS results confirmed that the metal-organic framework was coated on the wood surface, with the long-chain sodium laurate grafted onto it. The CoNi-DH-La@wood had a water contact angle of 151°, demonstrating excellent self-cleaning ability. In addition, the fabricated superhydrophobic balsa wood exhibited excellent chemical and environment stability. Lastly, the CoNi-DH-La@wood exhibited excellent anti-mildew properties in a 30-day anti-mildew test because the superhydrophobic coating was successfully coated on the wood surface. In summary, this work presents an attractive strategy for obtaining wood with superhydrophobic properties at room temperature, thereby endowing the wood or wood-based engineered products with excellent anti-mildew properties.

3 M antimicrobial incise drape combined with MEBO in wound recovery of postoperative hypospadias surgery.

OBJECTIVE: To evaluate the efficacy of different dressing methods in wound healing and the postoperative outcome in children who underwent hypospadias repair. METHODS: Altogether 109 children with distal hypospadias who underwent urethroplasty were recruited from our hospital between January 2021 and March 2023. All patients were randomized in two groups according to the different dressing methods: Group A receiving 3 M antimicrobial incise drape + MEBO (moisture-exposed burn ointment) and Group B receiving absorbent dressing + elastic bandage dressing. The age at surgery, operation time, bleeding during the dressing, postoperative changes in glans color, dressing fell off, comfort of children during the dressing, difficulty in dressing removal, and degree of pain during dressing removal were compared between the two groups. RESULTS: Differences in age at surgery (p = 0.337) and operation time (p = 0.055) were not significant between the two groups. The overall effectiveness of the dressing was better in Group A than that in Group B. Only five cases in Group A had blood leakage after dressing (p = 0.006), and there was no dressing dislocation (p < 0.001) or glans color abnormality (p < 0.001). Moreover, the number of complication cases was less. The overall comfort and pain degree during dressing removal in Group A was better than that in Group B (p < 0.001). CONCLUSION: Postoperative dressing using 3 M antimicrobial incise drape + MEBO can achieve lower incidence rates of bleeding during dressing, postoperative glans darkening, and dressing falling off, a lower pain degree during dressing removal, and a better overall comfort level than those of the control group. This method is cost-effective and clinically safe, which contributes to the postoperative recovery of children with hypospadias and is thus worth promoting and applying.

Clinical Pathway for Enhanced Recovery in the Management of Non-Variceal Upper Gastrointestinal Bleeding: A Randomized Controlled Trial.

Purpose: To explore the effects of the clinical pathway on the outcomes of patients with non-variceal upper gastrointestinal bleeding. Materials and Methods: Randomized controlled trial. The study was conducted in two medical centers in China from 1 June 2022 to 31 December 2022. Patients with a diagnosis of non-variceal upper gastrointestinal bleeding who provided written informed consent were consecutively assigned to the intervention group. The patients in the intervention group were treated using the clinical pathway, while the control group received routine care and follow-up. Time, cost, complications, and prognostic indicators were analyzed. Intentional-to-treat analysis and per-protocol analysis were used for data analysis. Results: A total of 114 eligible patients with non-variceal upper gastrointestinal bleeding were randomly divided into two groups and included in the intention-to-treat analysis. In addition, 106 patients were included in the per-protocol analysis. The median age of the 106 patients was 57 years (range, 18-92 years) and 83.0% were male. There were no significant differences between groups regarding the baseline characteristics. The intervention group demonstrated a statistically significantly shorter length of stay, lower hospital cost (ie, cost during hospitalization, cost in the emergency room, and cost in the ward), significantly fewer cases of complications, and a higher level of patient satisfaction when compared with the control group. There was no significant difference between the two groups in the rates of transfusion, repeat endoscopy, rebleeding readmission, and mortality. Conclusion: The implementation of the clinical pathway for patients with non-variceal upper gastrointestinal bleeding may help improve patient outcomes and satisfaction.

The incidence and risk factors of unplanned reoperation in endoscopic endonasal surgeries: a single center study.

The incidence of unplanned reoperation after surgery during the same hospitalization is considered one of most important evaluation indicators for health care quality. The purpose of this study was to determine the incidence and risk factors related to unplanned reoperation after an endoscopic endonasal approach (EEA). All patients who underwent elective endoscopic endonasal surgery from January 2016 to December 2021 in the Department of Neurosurgery, Tangdu Hospital, Air Force Military Medical University, were included. We identified the patients who underwent an unplanned reoperation and those who did not and divided them into two groups. The demographic data and risk factors were compared between the groups by univariate and multivariate logistic regression analyses. Of the 1783 patients undergoing EEA for various lesions of the skull base, the incidence of unplanned reoperation was 2.3%. The most common unplanned reoperations were repair of cerebrospinal fluid (CSF) leakage (39%), sellar hematoma evacuation (34.1%), hemostasis of epistaxis (14.6%) and external ventricular drainage for obstructive hydrocephalus (9.8%). The maximum diameter of tumor ≥ 3 cm (OR 2.654, CI 1.236-5.698; p = 0.012), meningioma (OR 4.198, CI 1.169-15.072; p = 0.028), craniopharyngioma (OR 5.020, CI 2.020-12.476; p = 0.001) and other sellar lesions (OR 4.336, CI 1.390-13.527; p = 0.012) and an operation time ≥ 240 min (OR 2.299, CI 1.170-4.518; p = 0.016) were the independent risk factors for unplanned reoperations in multivariate regression analysis. Of the 41 patients undergoing unplanned reoperation, 16 patients died, twenty-one patients had panhypopituitarism, 13 patients had transient and 6 had permanent diabetes insipidus, and 11 patients presented with intracranial infection and 6 of these patients were cured. By reviewing our department's data, we stated the incidence and risk factors for unplanned reoperation. It is important for the hospital administration and neurosurgeons to place more emphasis on these indicators. Furthermore, we suggest some effective quality improvement initiatives to reduce the incidence of unplanned reoperation.

A pregnant woman with a giant bilateral parietal hemangiopericytoma underwent multiple surgeries and radiotherapy: a case report and literature review.

Intracranial hemangiopericytoma is a rare invasive tumor originating from mesenchymal fibroblasts and is prone to local recurrence and distant metastasis. This study reports a case of a 27-year-old woman who presented with severe headache, nausea and vomiting for two weeks at thirty-three weeks of gestation. Cranial magnetic resonance imaging (MRI) demonstrated a giant lesion in the bilateral parietal lobe with a size of 5.12x9.19x6.03 cm and severe edema in the surrounding brain tissue. The patient underwent four operations and 3 gamma knife radiosurgery procedures and is recovering well now. The histopathology findings showed hemangiopericytoma and STAT6 and CD34 positivity after the first and second surgeries. Because of tumor progression, the patient received gamma knife radiosurgery at 1, 3, and 4 years after the first operation. Total tumor resection was achieved in the fourth surgery. Nevertheless, the patient showed malignant transformation to from low-grade to high-grade hemangiopericytoma.
