ABSTRACT
OBJECTIVE: In order to assess the associations between telomere length (TL) and diabetes mellitus (DM), especially type 2 diabetes (T2DM), we performed this systematic review and meta-analysis. METHODS: PubMed, Embase, and Web of Science were thoroughly searched up to July 11, 2023. The pooled standardized mean difference (SMD) and the 95% confidence interval (CI) were evaluated using the random-effects model. Age, sex, study design, duration of diabetes, region, sample size, and body mass index (BMI) were used to stratify subgroup analyses. RESULTS: A total of 37 observational studies involving 18,181 participants from 14 countries were included in the quantitative meta-analysis. In this study, patients with diabetes had shorter TL than the non-diabetic, whether those patients had T1DM (-2.70; 95% CI: -4.47, -0.93; P<0.001), T2DM (-3.70; 95% CI: -4.20, -3.20; P<0.001), or other types of diabetes (-0.71; 95% CI: -1.10, -0.31; P<0.001). Additionally, subgroup analysis of T2DM showed that TL was significantly correlated with age, sex, study design, diabetes duration, sample size, detection method, region, and BMI. CONCLUSION: A negative correlation was observed between TL and DM. To validate this association in the interim, more extensive, superior prospective investigations and clinical trials are required.
ABSTRACT
Marine-based dietary oils (MDOs), which are naturally obtained from different sources, have been scientifically recommended as potent functional bioactives owing to their therapeutic biological activities; however, they have exhibited plenty of health benefits. Though they are very sensitive to light, temperature, moisture, and oxygen, as well as being chemically unstable and merely oxidized, this may limit their utilization in food and pharmaceutical products. Miro- and nanoencapsulation techniques are considered to be the most promising tactics for enhancing the original characteristics, physiochemical properties, and therapeutic effects of entrapped MDOs. This review focuses on the biomacromolecule-stabilized micro/nanocarriers encompassing a wide range of MDOs. The novel-equipped polysaccharides and protein-based micro/nanocarriers cover microemulsions, microcapsules, nanoemulsions, and nanoliposomes, which have been proven to be encouraging candidates for the entrapment of diverse kinds of MDOs. In addition, the current state-of-the-art loading of various MDOs through polysaccharide and protein-based micro/nanocarriers has been comprehensively discussed and tabulated in detail. Biomacromolecule-stabilized nanocarriers, particularly nanoemulsions and nanoliposomes, are addressed as propitious nanocargos for protection of MDOs in response to thought-provoking features as well as delivering the successful, meticulous release to the desired sites. Gastrointestinal fate (GF) of biopolymeric micro/nanocarriers is fundamentally based on their centrifugation, dimension, interfacial, and physical properties. The external surface of epithelial cells in the lumen is the main site where the absorption of lipid-based nanoparticles takes place. MDO-loaded micro- and nanocarriers with biological origins or structural modifications have shown some novel applications that could be used as future therapies for cardiovascular disorders, thanks to today's cutting-edge medical technology. In the future, further investigations are highly needed to open new horizons regarding the application of polysaccharide and protein-based micro/nanocarriers in food and beverage products with the possibility of commercialization in the near future for industrial use.

Terminal acceptor atoms and side-chain functionalization play a vital role in the construction of efficient nonfullerene small-molecule acceptors (NF-SMAs) for AM1.5G/indoor organic photovoltaic (OPV) applications. In this work, we report three dithienosilicon-bridged carbazole-based (DTSiC) ladder-type (A-DD'D-A) NF-SMAs for AM1.5G/indoor OPVs. First, we synthesize DTSiC-4F and DTSiC-2M, which are composed of a fused DTSiC-based central core with difluorinated 1,1-dicyanomethylene-3-indanone (2F-IC) and methylated IC (M-IC) end groups, respectively. Then, alkoxy chains are introduced in the fused carbazole backbone of DTSiC-4F to form DTSiCODe-4F. From solution to film absorption, DTSiC-4F exhibits a bathochromic shift with strong π-π interactions, which improves the short-circuit current density (Jsc) and the fill factor (FF). On the other hand, DTSiC-2M and DTSiCODe-4F display up-shifting lowest unoccupied molecular orbital (LUMO) energy levels, which enhances the open-circuit voltage (Voc). As a result, under both AM1.5G/indoor conditions, the devices based on PM7:DTSiC-4F, PM7:DTSiC-2M, and PM7:DTSiCOCe-4F show power conversion efficiencies (PCEs) of 13.13/21.80%, 8.62/20.02, and 9.41/20.56%, respectively. Furthermore, the addition of a third component to the active layer of binary devices is also a simple and efficient strategy to achieve higher photovoltaic efficiencies. Therefore, the conjugated polymer donor PTO2 is introduced into the PM7:DTSiC-4F active layer because of the hypsochromically shifted complementary absorption, deep highest occupied molecular orbital (HOMO) energy level, good miscibility with PM7 and DTSiC-4F, and optimal film morphology. The resulting ternary OSC device based on PTO2:PM7:DTSiC-4F can improve exciton generation, phase separation, charge transport, and charge extraction. As a consequence, the PTO2:PM7:DTSiC-4F-based ternary device achieves an outstanding PCE of 13.33/25.70% under AM1.5G/indoor conditions. As far as we know, the obtained PCE results under indoor conditions are one of the best binary/ternary-based systems processed from eco-friendly solvents.
ABSTRACT
Literature is inconsistent regarding the effects of omega-3 polyunsaturated fatty acids (omega-3 PUFAs) supplementation on patients with metabolic syndrome (MetS) and related cardiovascular diseases (CVDs). Therefore, the aim of this systematic review and meta-analysis is to summarize data from available randomized controlled trials (RCTs) on the effect of omega-3 PUFAs on lipid profiles, blood pressure, and inflammatory markers. We systematically searched PubMed, Embase, and Cochrane Library databases to identify the relevant RCTs until 1 November 2022. Weighed mean difference (WMD) was combined using a random-effects model. Standard methods were applied to assess publication bias, sensitivity analysis, and heterogeneity among included studies. A total of 48 RCTs involving 8,489 subjects met the inclusion criteria. The meta-analysis demonstrated that omega-3 PUFAs supplementation significantly reduced triglyceride (TG) (WMD: -18.18 mg/dl; 95% CI: -25.41, -10.95; p < 0.001), total cholesterol (TC) (WMD: -3.38 mg/dl; 95% CI: -5.97, -0.79; p = 0.01), systolic blood pressure (SBP) (WMD: -3.52 mmHg; 95% CI: -5.69, -1.35; p = 0.001), diastolic blood pressure (DBP) (WMD: -1.70 mmHg; 95% CI: -2.88, -0.51; p = 0.005), interleukin-6 (IL-6) (WMD: -0.64 pg/ml; 95% CI: -1.04, -0.25; p = 0.001), tumor necrosis factor-α (TNF-α) (WMD: -0.58 pg/ml; 95% CI: -0.96, -0.19; p = 0.004), C-reactive protein (CRP) (WMD: -0.32 mg/l; 95% CI: -0.50, -0.14; p < 0.001), and interleukin-1 (IL-1) (WMD: -242.95 pg/ml; 95% CI: -299.40, -186.50; p < 0.001), and significantly increased in high-density lipoprotein (HDL) (WMD: 0.99 mg/dl; 95% CI: 0.18, 1.80; p = 0.02). However, low-density lipoprotein (LDL), monocyte chemoattractant protein-1 (MCP-1), intracellular adhesion molecule-1 (ICAM-1), and soluble endothelial selectin (sE-selectin) were not affected. In subgroup analyses, a more beneficial effect on overall health was observed when the dose was ≤ 2 g/day; Omega-3 PUFAs had a stronger anti-inflammatory effect in patients with CVDs, particularly heart failure; Supplementation with omega-3 PUFAs was more effective in improving blood pressure in MetS patients and blood lipids in CVDs patients, respectively. Meta-regression analysis showed a linear relationship between the duration of omega-3 PUFAs and changes in TG (p = 0.023), IL-6 (p = 0.008), TNF-α (p = 0.005), and CRP (p = 0.025). Supplementation of omega-3 PUFAs had a favorable effect on improving TG, TC, HDL, SBP, DBP, IL-6, TNF-α, CRP, and IL-1 levels, yet did not affect LDL, MCP-1, ICAM-1, and sE-selectin among patients with MetS and related CVDs.
ABSTRACT
Bischofia polycarpa seed oil is rich in nutrition and positively affects on human health. We analyzed and compared the chemical compositions, antioxidant activities, and quality characteristics of Bischofia polycarpa seed oils using different solvents and cold-pressing. Hx: Iso (n-hexane/isopropanol, 3:2 v/v) had the highest lipid yield (35.13 %), while Folch (chloroform/methanol, 2:1 v/v) had the highest linolenic acid (50.79 %), LnLnLn (43.42 %), and LnLnL (23.43 %). Tocopherols (2108.99 mg/kg) were extracted most efficiently with Folch, whereas phytosterols (3852.97 mg/kg) and squalene (55.21 mg/kg) were extracted most efficiently with petroleum ether. Although the lower phytosterol was obtained using isopropanol, the polyphenol content (271.34 mg GAE/kg) was significantly higher than other solvents, showing the best antioxidant ability. Additionally, polyphenols were observed to be the most significant factor predicting antioxidant activity from the correlation analysis. The above information can provide a useful reference for manufacturers to obtain satisfactory Bischofia polycarpa seed oil.
ABSTRACT
Molecular backbone modification, alkyl-chain engineering, and end-group functionalization are promising strategies for developing efficient high-performance non-fullerene acceptors (NFAs). Herein, two new NFAs, named TPQ-eC7-4F and TPQ-eC7-4Cl, are designed and synthesized. Both molecules have linear octyl chains on fused quinoxaline-containing heterocyclics as the central backbone and difluorinated (2F)/dichlorinated (2Cl) 1,1-dicyanomethylene-3-indanone (IC) as the end-group units. The influences of alkyl-chains on fused quinoxaline backbone and different halogenated end-groups on optical, electrochemical, and photovoltaic performances of organic solar cells (OSCs) are studied. In comparison with TPQ-eC7-4Cl, TPQ-eC7-4F exhibits blue-shifted absorptions with higher molar extinction coefficients in the film state as well as in the donor/acceptor (D/A) blend film state and up-shifting lowest unoccupied molecular orbital (LUMO) energy level. As a result, the OSC devices based on the PBDB-T:TPQ-eC7-4F display an outstanding power conversion efficiency (PCE) of 15.83% with a simultaneously increased open-circuit voltage (Voc) of 0.85 V, a short-circuit current-density (Jsc) of 25.89 mA cm-2, and a fill factor (FF) of 72.20%, whereas the PBDB-T:TPQ-eC7-4Cl-based OSC device shows a decent PCE of 14.48% with a Voc of 0.84 V, a Jsc of 24.56 mA/cm2, and an FF of 69.77%. To the best of our knowledge, this is the highest photovoltaic performance of PBDB-T-based single-junction binary-OSCs. In comparison, ascribed to the high crystallinity and low solubility of BTP-eC7-4Cl, the corresponding PBDB-T:BTP-eC7-4Cl-based OSC device shows poor photovoltaic performance (PCE of 11.87%). The experimental results demonstrate that fine-tuning the fused quinoxaline backbone with alkyl-chain and end-group functionalization are promising strategies to construct high-performance NFAs for PBDB-T-based single-junction binary-OSCs.
ABSTRACT
The molecular design of wide-bandgap conjugated polymer donors (WB-CPDs) is a promising strategy for tuning the bulk heterojunction blend film morphologies to achieve high-performance organic photovoltaic (OPV) devices. Herein, we synthesize two WB-CPDs, namely, PBQ-H and PBQ-M, with and without methyl groups on the fused-dithieno[3,2-f:2',3'-h]quinoxaline (DTQx) moiety. We systematically investigate their structure-property relationship and OPV performances. The AFM and 2D grazing-incidence wide-angle X-ray scattering (GIWAXS) studies reveal that the PBQ-H:BO-4Cl BHJ blend shows strengthened aggregation behavior and stronger π-π stacking on face-on orientation compared with the PBQ-M:BO-4Cl BHJ blend, enhancing the phase separation, charge transport, and fill factor (FF). Blend film absorption spectra, however, show that the PBQ-H:BO-4Cl BHJ blend exhibits a lower absorption coefficient than that of the PBQ-M:BO-4Cl BHJ blend, which decreases the short-circuit current density (JSC). As a consequence, the optimized PBQ-H:BO-4Cl BHJ blend delivers a higher power conversion efficiency (PCE) of 12.88% with a JSC of 23.97 mA/cm2, an open-circuit voltage (VOC) of 0.86 V, and an FF of 62.46%, compared with the PBQ-M:BO-4Cl BHJ blend (PCE of 11.81% with a JSC of 24.78 mA/cm2, a VOC of 0.85 V, and an FF of 56.11%). Overall, this work demonstrates that alkyl group substitution on the DTQx moiety on the basis of WB-CPDs is critical for controlling the film morphology and thus obtaining high OPV performances.
ABSTRACT
Power conversion efficiencies (PCEs) and device stability are two key technical factors restricting the commercialization of organic solar cells (OSCs). In the past decades, though the PCEs of OSCs have been significantly enhanced, device instability, especially in the state-of-the-art nonfullerene system, still needs to be solved. In this work, an effective crosslinker (namely, DTODF-4F), with conjugated fluorene-based backbone and crosslinkable epoxy side-chains, has been designed and synthesized, which is introduced to enhance the morphological stabilization of the PM6:Y6-based film. This crosslinker with two epoxy groups can be in situ crosslinked into a stable network structure under ultraviolet radiation. We demonstrate that DTODF-4F, which acted as a third component, can promote the exciton dissociation rate and reduce traps/defects, finally resulting in the enhancement of efficiency. In particular, the OSC devices exhibit better stability under continuous heating owing to the morphology fixation of the bulk heterojunction. This work drives the development direction of morphological stabilization to further improve the performance and stability of OSCs.
ABSTRACT
In this work, two asymmetric non-fullerene acceptors (NFAs), BTP-EHBO-4F and BTP-PHD-4F, are designed to be applied in green-solvent-processable organic photovoltaics (OPVs). BTP-EHBO-4F and BTP-PHD-4F show good solubilities in green solvent o-xylene. As a result, PM6:BTP-EHBO-4F-based devices exhibit outstanding photovoltaic performances using o-xylene as a solvent. By comparison, due to the poor solubility of Y6 in o-xylene, PM6:Y6-based devices show poor performances. Owing to the favorable phase separation, molecule packing, and orientation observed from atomic force microscopy (AFM) and grazing-incidence wide-angle X-ray scattering (GIWAXS) measurements, PM6:BTP-PHD-4F-based devices demonstrate a PCE of 15.91% with a VOC of 0.87 V, a JSC of 25.64 mA/cm2, and an FF of 71.34%. Moreover, PM6:BTP-EHBO-4F-based devices exhibit an impressive PCE of 16.82% with a VOC of 0.85 V, a JSC of 26.12 mA/cm2, and an FF of 75.78%, which is outstanding for OPVs using o-xylene as a solvent.
ABSTRACT
Thrombolytic therapy plays an important role in treating venous thromboembolic events in patients with unstable hemodynamics or compromised limb circulation. Standard catheter-directed thrombolysis requires a lower dosage of thrombolytic agents than systemic thrombolysis, thus lowering the risk of bleeding. Pharmacomechanical catheter- directed thrombolysis further decreases the dose of thrombolytic agents and duration of infusion. Percutaneous mechanical thrombolysis may potentially become an alternative for patients not suitable for thrombolytic agents. With an increasing number of devices and ongoing trials, endovascular therapy is a promising development that may improve both safety and efficacy in treating venous thromboembolic diseases.
ABSTRACT
In this work, two DTSiC-based nonfullerene acceptors (NFAs), (2,2'-((2Z,2'Z)-((12-(heptadecan-9-yl)-4,4,7,7-tetraoctyl-7,12-dihydro-4H-thieno[2',3':4,5]silolo[3,2-b]thieno[2',3':4,5]silolo[2,3-h]carbazole-2,9-diyl)bis(methaneylylidene))bis(3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile) (DTSiC-IC) and (2,2'-((5Z,5'Z)-((12-(heptadecan-9-yl)-4,4,7,7-tetraoctyl-7,12-dihydro-4H-thieno[2',3':4,5]silolo[3,2-b]thieno[2',3':4,5]silolo[2,3-h]carbazole-2,9-diyl)bis(methaneylylidene))bis(6-oxo-5,6-dihydro-4H-cyclopenta[c]thiophene-5,4-diylidene))dimalononitrile) (DTSiC-TC), are designed with various end groups (IC and TC). To explore the effect of end-group modifications, photovoltaic performance under AM 1.5G and indoor conditions are comprehensively studied. Compared with DTSiC-IC, DTSiC-TC manifests red-shifted and stronger absorption, downshifted lowest unoccupied molecular orbital (LUMO), and pronounced face-on packing characteristics. As we envisaged, the PM7:DTSiC-TC-based devices outperform the PM7:DTSiC-IC-based devices in both AM 1.5G and indoor (light-emitting diode (LED) 3000 K 1000 lux) conditions with overall higher JSC, FF, and power conversion efficiency (PCE). Furthermore, the PM7:DTSiC-TC-based devices achieve an outstanding PCE of 20.73% with a VOC of 0.87 V, a JSC of 0.095 mA/cm2, and an FF of 70.86%.
ABSTRACT
PURPOSE: This meta-analysis was conducted to assess the effects of telemedicine interventions on continuous positive airway pressure (CPAP) adherence in patients with obstructive sleep apnoea (OSA). METHODS: The PubMed, Cochrane Library, OVID, Web of Science and EBSCO host databases were searched from January 2004 to February 2020 for randomised controlled trials (RCTs) that assessed the effects of telemedicine interventions on CPAP adherence in patients with OSA. The study inclusion criteria were RCTs that compared patients who received telemedicine interventions with a control group and reported a change in CPAP adherence. The primary outcome was the improvement in CPAP adherence. RESULTS: In total, there were 11 RCTs (n = 1358) with quantitative analyses. Intervention times ranged from 1 to 6 months. Compared to controls, the telemedicine group exhibited better adherence to CPAP therapy (pooled mean difference (MD) = 0.57, 95% CI = 0.33 to 0.80, I2 = 7%, p < 0.00001). We performed sensitivity analyses by the type of telemedicine intervention, comorbidity burden, and OSA severity to explore whether or not their effect sizes may have affected the time of CPAP application. We performed subgroup analyses by follow-up duration, age, and OSA Epworth sleepiness scale (ESS) symptoms to determine if their effect sizes may have affected the time of CPAP application. However, these analyses did not change the statistical significance of the pooled estimate. CONCLUSIONS: The use of telemedicine for up to 6 months may enhance CPAP adherence in patients with OSA, when compared to no intervention. Our study was searched from January 2004 to February 2020 for randomised controlled trials (RCTs) that assessed the effects of telemedicine interventions on CPAP adherence in patients with OSA. Future studies can continue to search for articles after February 2020.

Recent advances in mobile augmented reality (AR) techniques have shed new light on personal visualization for their advantages of fitting visualization within personal routines, situating visualization in a real-world context, and arousing users' interests. However, enabling non-experts to create data visualization in mobile AR environments is challenging given the lack of tools that allow in-situ design while supporting the binding of data to AR content. Most existing AR authoring tools require working on personal computers or manually creating each virtual object and modifying its visual attributes. We systematically study this issue by identifying the specificity of AR glyph-based visualization authoring tool and distill four design considerations. Following these design considerations, we design and implement MARVisT, a mobile authoring tool that leverages information from reality to assist non-experts in addressing relationships between data and virtual glyphs, real objects and virtual glyphs, and real objects and data. With MARVisT, users without visualization expertise can bind data to real-world objects to create expressive AR glyph-based visualizations rapidly and effortlessly, reshaping the representation of the real world with data. We use several examples to demonstrate the expressiveness of MARVisT. A user study with non-experts is also conducted to evaluate the authoring experience of MARVisT.
ABSTRACT
Integrating an additional component featuring complementary light absorption into binary polymer solar cells is a superior tactic to ameliorate solar cell efficiency and stability. An appropriate additive not only extends the absorption range but may also facilitate charge separation and transport processes. In this work, we elucidate the effects of incorporating a porphyrin-containing conjugated polymer (PPor-1), which displays absorption in 350-500 nm, into binary PTB7-Th:4TIC and PTB7-Th:ITIC blends, affording devices with an average power conversion efficiency approaching 9%. We successfully demonstrate that PPor-1 can be incorporated as an additive to impart improved Jsc (up to 19.1 mA cm-2).
