Neural underpinnings of processing combinatorial unstated meaning and the influence of individual cognitive style.

We investigated the neurocognitive mechanisms underlying the processing of combinatorial unstated meaning. Sentences like "Charles jumped for 5 minutes." engender an iterative meaning that is not explicitly stated but enriched by comprehenders beyond simple composition. Comprehending unstated meaning involves meaning contextualization-integrative meaning search in sentential-discourse context. Meanwhile, people differ in how they process information with varying context sensitivity. We hypothesized that unstated meaning processing would vary with individual socio-cognitive propensity indexed by the Autism-Spectrum Quotient (AQ), accompanied by differential cortical engagements. Using functional magnetic resonance imaging, we examined the processing of sentences with unstated iterative meaning in typically-developed individuals and found an engagement of the fronto-parietal network, including the left pars triangularis (L.PT), right intraparietal (R.IPS), and parieto-occipital sulcus (R.POS). We suggest that the L.PT subserves a contextual meaning search, while the R.IPS/POS supports enriching unstated iteration in consideration of event durations and interval lengths. Moreover, the activation level of these regions negatively correlated with AQ. Higher AQ ties to lower L.PT activation, likely reflecting weaker context sensitivity, along with lower IPS activation, likely reflecting weaker computation of events' numerical-temporal specifications. These suggest that the L.PT and R.IPS/POS support the processing of combinatorial unstated meaning, with the activation level modulated by individual cognitive styles.

Comparison of puncture methods in patients with hemodialysis: A randomized controlled trial.

INTRODUCTION: Arteriovenous fistula or arteriovenous graft is essential to long-term survival and quality of life in patients receiving hemodialysis. To date, no research has examined the clinical impacts of different puncture methods. This study compared the rope ladder and area puncture techniques in terms of vascular patency, pain, and quality of life among patients receiving hemodialysis. METHODS: A prospective longitudinal study was performed with 6-month follow-up. A total of 98 participants recruited from a hemodialysis center in Taiwan were randomly assigned to receive the rope ladder technique (experimental group) or the area puncture technique (control group). Vascular patency was assessed by examining access flow and percutaneous transluminal angioplasty rate. Pain and quality of life were measured using the Numerical Pain Rating Scale (NPRS) and Kidney Disease Quality of Life Instrument (KDQOL-36™), respectively. All outcome variables were measured repeatedly and analyzed using a generalized estimating equation. RESULTS: Overall, quality of life was significantly better for the experimental group than for the control group (ß = 47.23, p < 0.001). The percutaneous transluminal angioplasty rate was lower for the experimental group than for the control group (12.0% vs. 18.8%). However, no significant differences were found in access flow and pain level between the two groups over time. CONCLUSION: Hemodialysis patients who received the rope ladder puncture technique had a lower percutaneous angioplasty rate and better quality of life than patients who received the area puncture technique, suggesting that the rope ladder technique could be implemented as a routine cannulation method in hemodialysis clinics.

Low-level laser therapy combined with scleral graft transplantation in the treatment of contracted socket: a clinical study.

OBJECTIVE: To analyse the efficacy of the therapeutic use of low-level laser therapy (LLLT) on the tissue repair process of allogeneic scleral grafts in patients with contracted sockets by analysing the speed of graft vascularisation and fornice depth of contraction percentage. METHODS: A retrospective chart review was performed from April 2015 to April 2021 including 39patients with socket contraction. Allogeneic scleral grafts were used to repair the sockets in all patients. They were randomly enrolled into two groups. The laser group included 18 patients treated with LLLT after the surgery, whereas the control group included 21 patients without LLLT after the surgery who healed naturally. The LLLT equipment used in the research had a wavelength of 650 nm, 10 mW power, and 3.8 J/cm2 dosimetry, and the procedure was performed once daily for 5 min over 7 days, beginning 1 week postoperatively. All patients were followed up over 6 months to examine the changes in the size of the area of the non-vascularised graft and upper and inferior fornice depth. RESULTS: The laser group presented a significantly increased speed of conjunctival vascularisation compared with the control group (P = 0.003). The fornice depth of contraction percentage was more apparent in the control group than that in the laser group (P = 0.000). CONCLUSION: LLLT accelerates conjunctival vascularisation, stimulates conjunctival incision healing within a short period, shortens the tissue repair process, reduces the local inflammatory response, and causes no significant shrinkage of the conjunctival sac.

Authentic leadership and employee resilience during the COVID-19: The role of flow, organizational identification, and trust.

The present work investigated fundamental mediating mechanisms (i.e., flow experience, organizational identification, and trust), underlining the impact of authentic leadership on employee resilience during the turbulent COVID-19 pandemic. A total of 901 frontline employees working in a construction engineering company in China participated in this study. They were asked to respond to a battery of questionnaires comprising Trust Scale (affective-based, cognitive-based, and competence-based), Flow Proneness Questionnaire (FPQ), Organizational Identification Scale, Authentic Leadership Questionnaire, and Employee Resilience Scale. Results of structural equation modeling indicated that: (1) Authentic leadership positively predicted employee resilience in the COVID-19 pandemic, directly and indirectly. (2) As for the indirect relationship, two parallel mediation effects and one chain mediation were detected: employees' flow at work and organizational identification respectively and dependently mediated the relationship between authentic leadership and employee resilience; trust and organizational identification played as a chain mediation role within authentic leadership-employee resilience association. The study provides empirical evidence for organizations' resilience-building and leadership training programs. Findings also contribute to the literature by facilitating flow intervention, promoting organizational identification and trust to enhance the effect of authentic leadership in promoting positive psychological functioning of employee resilience. Limitations with respect to future research directions were also outlined.

Comparative efficiency and safety of insulin degludec/aspart with insulin glargine in type 2 diabetes: a meta-analysis of randomized controlled trials.

Recent studies have found compared with insulin glargine (IGlar), insulin degludec/aspart (IDeg/Asp) may provide adequate glycemic control and prevent hypoglycemia events in type 2 diabetes mellitus (T2DM). Consequently, we performed a meta-analysis to appraise and compare the efficiency and safety of IDeg/Asp and IGlar in the treatment of T2DM. We sought the databases including PubMed, Embase, Scopus, Cochrane library to confirm related articles which inspected the effect of IDeg/Asp versus IGlar for the treatment of T2DM until May 2021. Finally, six randomized controlled trials (RCTs) of 1,346 patients were included. The results showed that IDeg/Asp significantly decreased the mean hemoglobin A1c (HbA1c) level but was prone to serious adverse events, and IGlar increased the nocturnal confirmed hypoglycemia events. Besides, there were no significant changes in other indicators, including mean fasting plasma glucose (FPG) level, nine-point self-measured plasma glucose (SMPG) level, and adverse events. What's more, we found that there was no significant difference in the occurrence of hypoglycemia overall, but our subgroup analysis of confirmed hypoglycemia revealed the population in this subgroup (duration of diabetes ≤11 years) might has its particularity effecting the hypoglycemia outcome. Concerning efficiency, IDeg/Asp may have advantages in controlling the mean HbA1c level. Regarding safety, IGlar might increase the risk of nocturnal confirmed hypoglycemia. Further evidence is needed to compare better the efficiency and safety of IDeg/Asp versus IGlar therapy.

Luteolin inhibits the proliferation, adhesion, migration and invasion of choroidal melanoma cells in vitro.

Choroidal melanoma is a devastating disease that causes visual loss and a high mortality rate due to metastasis. Luteolin, a potential anticancer compound, is widely found in natural plants. The aim of this study was to evaluate the antiproliferative, antiadhesive, antimigratory and anti-invasive effects of luteolin on choroidal melanoma cells in vitro and to explore its potential mechanism. Cell counting kit-8 (CCK-8) assays, 5-ethynyl-2'-deoxyuridine (EdU) assays, Cell adhesion, migration, and invasion assays were performed to examine the inhibitory effects of luteolin on cell cell viability, proliferation, adhesion, migration and invasion capacities, respectively. Considering the correlation between Matrix metalloenzymes and tumor metastasis, Enzyme-linked immunosorbent assays (ELISAs) were used to assess matrix metalloproteases MMP-2 and MMP-9 secretion. Western blotting was performed to detect p-PI3K P85, Akt, and p-Akt protein expression. The cytoskeletal proteins vimentin were observed with cell immunofluorescence staining. Luteolin can inhibit OCM-1 cell proliferation, migration, invasion and adhesion and C918 cell proliferation, migration, and invasion through the PI3K/Akt signaling pathway. Therefore, Luteolin may have potential as a therapeutic medication for Choroidal melanoma.

Ionic Self-Assembled Derivative of Tetraphenylethylene: Synthesis, Enhanced Solid-State Emission, Liquid-Crystalline Structure, and Cu2+ Detection Ability.

A novel tetraphenylethylene complex composed of 4',4'',4''',4''''-(ethene-1,1,2,2-tetrayl)tetrabiphenyl-4-carboxylic acid (H4 ETTC) and dimethyldioctadecylammonium bromide (DOAB) with enhanced solid-state emission is designed and synthesized through an ionic self-assembly (ISA) strategy. The aggregation-induced emission property, phase behavior, and supramolecular structure of the complex are characterized by a combination of experimental measurements. The experimental results reveal that the ISA complex can self-assemble into an ordered helical supramolecular structure with enhanced luminescent properties, although the ETTC cores possess extensive conjugation and high rigidity. Due to the prolonged conjugation length, the fluorescence quantum yield of ETTC-DOAB is boosted to 66 %. Moreover, it is demonstrated that assemblies of the ISA complex are an effective sensor for Cu2+ . Owing to the disassembly modulation of ETTC-DOAB aggregations, the fluorescence emission of the assemblies can be selectively and sensitively quenched by Cu2+ , with a detection limit as low as 12.6 nm. The enhanced emission efficiency, in combination with the liquid crystallinity and superior sensing performance to Cu2+ , make the ETTC-DOAB complex a potential candidate for the fabrication of a luminescent device and chemosensor for Cu2+ detection.

ZnO-coated carbon nanotubes: inter-diffusion of carboxyl groups and enhanced photocurrent generation.

ZnO is a defect-governed oxide and emits light at both visible and UV regimes. This work employs atomic layer deposition to produce oxide particles on oxygenated carbon nanotubes, and the composites only show emission profiles at short wavelengths. The quenching of defect-related emissions at long wavelengths is verified, owing to carboxyl diffusion into oxygen vacancies, and doping is supported by ZnCO3 formation in oxide lattice. Fully coated tubes display an increased photocurrent and the quantum efficiency increases by 22 % relative to the bare nanotubes.

Carbon nanotubes enhanced Seebeck coefficient and power factor of rutile TiO2.

The Seebeck coefficient, according to Ioffe's approximation, is inversely proportional to carrier density and decreases with doping. Herein, we find that the incorporation of multi-walled carbon nanotubes into rutile TiO2 improves the electrical conductivity and Seebeck coefficient at a low filling fraction of tubes; moreover, the former was due to the lengthening of the mean free path and doping modified carrier mobility for the latter. Tube-oxide mixing also causes significant phonon drag at the interfaces and the reduced thermal conductivity was verified by the promoted figure of merit.

[Jinghuaweikang gelatin pearls plus proton pump inhibitor-based triple regimen in the treatment of chronic atrophic gastritis with Helicobacter pylori infection: a multicenter, randomized, controlled clinical study].

OBJECTIVE: To observe the efficacy of Jinghuaweikang gelatin pearls plus proton pump inhibitor (PPI)-based triple regimen in the treatment of chronic atrophic gastritis (CAG) patients with Helicobacter pylori (H.pylori) infection. METHODS: For this multicenter, randomized, controlled clinical study, 90 patients of endoscopically confirmed CAG with positive H.pylori ((13)C or (14)C-urea breath test (UBT) or rapid urease test) were enrolled. There were 46 males and 44 females with an age range of (54 ± 10) years. None of them had H.pylori eradication background. They were randomly divided into 2 groups, Group LACJ (n = 45) received lansoprazole 30 mg+amoxicillin 1000 mg+clarithromycin 500 mg + jinghuaweikang gelatin pearls 240 mg, twice daily, for 10 days (d1-10) plus another 14 days (d11-24) only with jinghuaweikang gelatin pearls 240 mg, twice daily. Group LACB (n = 45) had standard quadruple regimen treatment: lansoprazole 30 mg+amoxicillin 1000 mg+clarithromycin 500 mg+bismuth potassium citrate 220 mg, twice daily for 10 days (d1-10). The status of H.pylori was detected by (13)C-UBT at least 28 days after therapy. RESULTS: The eradication rates in Groups LACJ and LACB were as follows: per-protocol (PP): 70.5% (31/44) and 83.3% (35/42), intention-to-treat (ITT): 68.9% (31/45) and 77.8% (35/45) (both P > 0.05). The symptomatic improvements of bloating in upper abdomen, belching and epigastric pain after treatment in both groups. And those in Group LACJ was higher than those of Group LACB, but no statistical difference existed between two groups (all P > 0.05). CONCLUSIONS: The efficacy of LACJ for the treatment of CAG patients with H.pylori infection is similar to LACB. And the symptomatic improvement of patients is better than LACB.

Authentic Leadership and Employee Resilience: A Moderated Mediation Analysis.

Authentic leadership is essential for predicting employee resilience. However, despite fruitful findings, more adapted models of authentic leadership - employee resilience based on empirical findings can serve as a guide to understand the complex mediators and moderators in different industries such as in construction engineering project organizations during the turbulent pandemic. This study, therefore, based on the organizational identification theory and flow theory through the lens of positive organizational psychology, aims to disentangle the authentic leadership-employee resilience association by investigating their underlying mechanism and their boundary condition. To test our hypothetical model, we applied a cross-sectional design with data collected from a large sample of 884 employees from a big enterprise in China. Findings from confirmatory factor analysis, structural equation modeling analysis, and Hayes's conditional process model indicated that: authentic leadership positively predicted employee resilience through the partial mediation effect of organizational identification, and such a mediation model was moderated by the experience of flow. In other words, flow moderated the relationships between authentic leadership, organizational identification, and employee resilience. Findings provide evidence for cultivating leaders' authenticity in promoting their subordinates' resilience; findings also highlight the significance of organizational identification in bridging authentic leadership and employee resilience and the essential role of flow experience in supporting the relationships mentioned above.

Long non-coding RNA GAS6-AS1 enhances breast cancer cell aggressiveness by functioning as a competing endogenous RNA of microRNA-215-5p to enhance SOX9 expression.

Long non-coding (lnc) RNAs play crucial functions in human cancer. However, until recently, the involvement of the lncRNA GAS6-AS1 in breast cancer (BCa) malignancy has not been studied exhaustively. The roles and underlying mode of action of GAS6-AS1 action in BCa progression were examined through functional experiments. A decline in GAS6-AS1 level led to a significant decrease in BCa cell proliferation, and the ability for colony formation. Here, GAS6-AS1 competed as endogenous RNA by sequestering microRNA-215-5p (miR-215-5p) causing an enhanced expression of SRY-box transcription factor 9 (SOX9). The effects of silencing GAS6-AS1 on BCa malignant phenotypes could be ameliorated by inhibiting miR-215-5p or restoring SOX9. Thus, GAS6-AS1 acted as a lncRNA that drives tumor in BCa, and enabled progression of BCa through miR-215-5p /SOX9 axis regulation. These outcomes show that the GAS6-AS1/miR-215-5p/SOX9 axis is a potentially effective target for cancer treatment and management.

Why aggregated carbon nanotubes exhibit low quantum efficiency.

Aggregation of carbon nanotubes reduces quantum efficiency and the phenomenon is found to be related to photocurrent leakage through oxygenated lattices acting as low barrier intertube channels. This outcome is supported by calculation and optical excitation experiments.

Flow as a Key Predictor of Subjective Well-Being Among Chinese University Students: A Chain Mediating Model.

The present study investigated a conceptual model by testing flow experience and subjective well-being of university students during Coronavirus Diseas-19 (COVID-19) via considering their underlying mechanisms of academic self-efficacy and self-esteem. A total of 1,109 Chinese university students completed a questionnaire containing scales of subjective well-being, flow, academic self-efficacy, and self-esteem. Results yielded from the structural equation modeling analysis indicated a significant and positive association between flow experience and subjective well-being, and such an association was sequentially mediated by academic self-efficacy and self-esteem. Findings also provided empirical evidence for the proposed model highlighting the significant role of flow experience at the higher educational context in predicting subjective well-being of Chinese university students, and how such a relation can be supported by suggested mediating roles academic self-efficacy and self-esteem played.

Analysis of the Biochemical Reaction Status by Real-Time Monitoring Molecular Diffusion Behaviors Using a Transistor Biosensor Integrated with a Microfluidic Channel.

Traditional methods of monitoring biochemical reactions measure certain detectable reagents or products while assuming that the undetectable species follow the stoichiometry of the reactions. Here, based upon the metal-oxide thin-film transistor (TFT) biosensor, we develop a real-time molecular diffusion model to benchmark the concentration of the reagents and products. Using the nicotinamide adenine dinucleotide (NADH)-oxaloacetic acid with the enzyme of malate dehydrogenase as an example, mixtures of different reagent concentrations were characterized to extract the ratio of remaining concentrations between NAD+ and NADH. We can thus obtain the apparent equilibrium constant of the reaction, (8.06 ± 0.61) × 104. Because the whole analysis was conducted using a TFT sensor fabricated using a semiconductor process, our approach has the advantages of exploring biochemical reaction kinetics in a massively parallel manner.

Precise resection of multiple pulmonary nodules using a three-dimensional reconstruction model: A case report.

A 48-year-old woman presented to our department and chest computed tomography (CT) revealed five pulmonary nodules, two of which were in the left upper lobe of the lung and three in the superior segment of the left lower lobe., All the lesions were resected for comprehensive histological assessment in order to distinguish synchronous multiple primary lung cancers (SMPLCs) from intrapulmonary metastases. The nodules were all successfully removed by minimally invasive surgery under the guidance of three dimensional (3D) reconstruction, in order to preserve as much lung function for the patient as possible. Postoperative histopathological examination demonstrated the presence of SMPLC. The patient was discharged from hospital on postoperative day 4 without any complications.

Oscillation induced worm-like locomotion of carbon nanotubes.

Harmonic oscillation of a doubly clamped single-walled carbon nanotube rope is significantly damped by the resistive force of friction at intertube contacts and the energy transmission rate has been estimated to be lower than that on a metal wire excited at similar frequency and vibrating length by one order of magnitude.

Review of Integrated Optical Biosensors for Point-Of-Care Applications.

This article reviews optical biosensors and their integration with microfluidic channels. The integrated biosensors have the advantages of higher accuracy and sensitivity because they can simultaneously monitor two or more parameters. They can further incorporate many functionalities such as electrical control and signal readout monolithically in a single semiconductor chip, making them ideal candidates for point-of-care testing. In this article, we discuss the applications by specifically looking into point-of-care testing (POCT) using integrated optical sensors. The requirement and future perspective of integrated optical biosensors for POC is addressed.

Characterizations of protein-ligand reaction kinetics by transistor-microfluidic integrated sensors.

Understanding the binding affinities and kinetics of protein-ligand interactions using a label-free method is crucial for identifying therapeutic candidates in clinical diagnostics and drug development. In this work, the IGZO-TFT (thin-film transistor) biosensor integrated with a tailored microfluidic chip was developed to explore binding kinetics of protein-ligand biochemical interactions in the real-time manner. The IGZO-TFT sensor extracts the binding characteristics through sensing biomolecules by their electrical charges. Using lysozyme and tri-N-acetyl-D-glucosamine (NAG3) as an example, we established a procedure to obtain the parameters, such as the dissociation constant, Kd, and association rate constant, ka, that are critical to biochemical reactions. The correlation between the lysozyme concentration and TFT drain current signal was first constructed. Next, solutions of lysozyme and NAG3 of different mixing ratios were prepared. They were pre-mixed for various periods of reaction time before applying to the TFT sensor to extract signals of lysozyme molecules and the concentration remaining. With the knowledge of drain current changes at different reaction times, ka and Kd can be obtained. The values from our experiment are comparable to other methods, which suggests the proposed approach can be employed to explore protein-ligand interaction kinetics in the massively parallel manner if the TFT array is considered.
