Bio-based adsorption foam composed of MOF and polyethyleneimine-modified cellulose for selective anionic dye removal.

With the increase of sustainable development goal, the bio-based adsorption materials with high and selective dye removal are important for water treatment in the dyeing industry. In this paper, a bio-based adsorption foam composed of metal-organic frameworks (MOF) and polyethyleneimine (PEI)-modified cellulose was prepared by a three-step process, i.e., PEI modification of cellulose fibers (PC), MOF decoration of PEI-modified cellulose (MIL-53@PC), and in-situ foaming with polyurethane. PEI modification provides cellulose fiber with more active sites for both dye adsorption and MOF bonding. We found that MIL-53 crystals were tightly bonded on the surface of PC through hydrogen bonding. Because of the abundant adsorption sites (e.g., amines, iron oxide group), the MIL-53@PC demonstrated high adsorption capacity and selectivity for anionic dye (e.g., 936.5 mg/g for methyl orange) through electrostatic interaction and hydrogen bonding. Finally, MIL-53@PC particles were blended with a waterborne polyurethane prepolymer to prepare a three-dimensional hydrophilic foam (MIL-53@PC/PUF), which not only maintained high adsorption capacity and selectivity of MIL-53@PC and also improved its recyclability and reusability. The MIL-53@PC/PUF offers a promising solution for dye wastewater treatment.

Integrin α4 Positive Subpopulation in Adipose Derived Stem Cells Effectively Reduces Infarct Size through Enhanced Engraftment into Myocardial Infarction.

The efficacy of adipose-derived stem cells (ASCs) on myocardial infarction is limited due to poor survival and engraftment. Integrin-mediated cell adhesion is a prerequisite for its survival and homing. ASCs expressed insufficient integrin α4, limiting their homing capacity. This study aims to characterize integrin α4＋ ASC subpopulation and investigate their therapeutic efficacy in myocardial infarction. We used fluorescence-activated cell sorting to harvest integrin α4＋ ASCs subpopulation, which were characterized in vitro and transplanted into myocardial infarction model. Positron emission tomography imaging were performed to measure infarction size. Cardiac cine magnetic resonance imaging was used to evaluate heart contractile function. Compared with the unfractionated ASCs, integrin α4＋ ASCs subpopulation secreted a higher level of angiogenic growth factors, migrated more rapidly, and exhibited a stronger anti-apoptotic capacity. Vascular cell adhesion molecule-1 was obviously up-regulated at 3 days after myocardial infarction, which interacted with integrin α4 receptor on the surface of ASCs to enhance the survival and adhesion. Thus, we implanted unfractionated ASCs or integrin α4＋ ASCs subpopulation into the 3-day infarcted myocardium. Integrin α4＋ ASCs subpopulation exhibited more robust engraftment into the infarcted myocardium. Integrin α4＋ ASCs subpopulation more effectively decreased infarct size and strengthen cardiac function recovery than did the unfractionated ASCs. Integrin α4＋ ASCs subpopulation is superior to unfractionated ASCs in ameliorating ischemic myocardial damage in animal model. Mechanistically, their more robust engraftment into the infarct area, higher migratory capacity and their increased release of paracrine factors contribute to enhanced tissue repair.

Simple ultrasonic integration of shapeable, rebuildable, and multifunctional MIL-53(Fe)@cellulose composite for remediation of aqueous contaminants.

Metal-organic frames (MOFs) have been recognized as one of the best candidates in the remediation of aqueous contaminants, while the fragile powder shape restricts the practical implementation. In this work, a shapeable, rebuildable, and multifunctional MOF composite (MIL-53@CF) was prepared from MIL-53 (Fe) and cellulose fiber (CF) using a simple ultrasonic method for adsorption and photocatalytic degradation of organic pollutants in wastewater. The results showed MIL-53(Fe) crystals were uniformly growth on CF surfaces and bonded with surface nanofibrils of CF through physical crosslinking and hydrogen bonding. Because of the high bonding strength, the MIL-53@CF composite exhibited an excellent compressive strength (3.53 MPa). More importantly, the MIL-53@CF composite was rebuildable through mechanical destruction followed by re-ultrasonication, suggesting the excellent reusability of MIL-53@CF for water remediation. The MIL-53@CF composite also had high adsorption capacities for methyl orange (884.6 mg·g-1), methylene blue (198.3 mg·g-1), and tetracycline (106.4 mg·g-1). MIL-53@CF composite could degrade TC through photocatalysis. The photocatalytic degradation mechanism was attributed to the Fe(II)/Fe(III) transform cycle reaction of MIL-53 crystal located on MIL-53@CF. Furthermore, the mechanical property and remoldability of MIL-53@CF composite increased its practicability. Comprehensively, MIL-53@CF composite provided a possible strategy to practically apply MOF in the remediation of aqueous contaminants.

Negative family body talk and negative emotional eating among Chinese adolescent girls and young adult women: The role of body dissatisfaction and feminism consciousness.

Negative emotional eating has been increasingly a prominent disordered eating and public health problem among young women, especially during COVID-19. Although previous studies have attempted to explain the relationship between body talk and negative emotional eating, limited studies focused on examining the potential mechanisms, especially the potential protective mechanism. Thus, the current study aimed to examine the relationship between negative family body talk (NFBT) and negative emotional eating, as well as its underlying mechanism - the mediating role of body dissatisfaction (BDIS) and the moderating role of feminism consciousness (FC). A cross-sectional study was employed among a sample of Chinese girls and young women (n = 813, Mage = 19.4 years) from a junior college in central China. Participants completed surveys assessing NFBT (Adapted Body Talk Scale), BDIS (Body Image State Scale), negative emotional eating (Dutch Eating Behavior Questionnaire), and FC (Synthesis Subscale from Feminist Identity Composite). A moderated mediation analysis was conducted. The results showed that: (1) after controlling for age and BMI, NFBT was positively associated with negative emotional eating, and BDIS could significantly mediate this relationship (mediating effect = 0.03, 95% CI [0.02, 0.06]); (2) FC significantly moderated both the direct relationship between NFBT and negative emotional eating and the relationship between NFBT and BDIS. Specifically, these two associations were not significant for participants with higher FC (+1SD above average). This study deepens our understanding of the relationship between NFBT and negative emotional eating, as well as the protective role of FC. If future studies demonstrate causal relationships, this evidence could point to a need for programs to prevent negative emotional eating in young women by increasing their level of feminism consciousness.

Parental Phubbing and Adolescent Depressive Symptoms during COVID-19: A Serial Meditating Model.

BACKGROUND: During the COVID-19 pandemic, depressive symptoms, a common emotional problem among adolescents, have become more prominent. Regarding the influencing factors of adolescent depressive symptoms, it is widely accepted that parents' problematic cellphone use around the family (specifically parental phubbing) is a strong predictive factor for the development of depressive symptoms among adolescents. Notably, the COVID-19 pandemic caused a sharp increase in the number of individuals with depressive symptoms, and the negative consequences of parental phubbing and depressive symptoms might have been exacerbated. Accordingly, this study aimed to examine the association between parental phubbing and adolescent depressive symptoms as well as their underlying mechanism. METHOD: To test our hypotheses, we conducted an offline/online survey with 614 adolescents in Central China from May to June 2022, which corresponded to a period of strict lockdowns in some areas due to the outbreak of the Omicron variant. The participants completed a set of measures, including a technology interference questionnaire, a parent-child relationship scale, a self-concept clarity scale, and the depressive symptoms scale. RESULTS: Parental phubbing was positively associated with adolescent depressive symptoms; the parent-child relationship and self-concept clarity could independently mediate this relationship; and the parent-child relationship and self-concept clarity were also serial mediators in this association. These findings extend previous research by highlighting the impact of parental technology use on their children and the underlying mechanism explaining adolescent depressive symptoms. They provide practical recommendations for parents to prioritize fostering a positive family environment and minimizing phubbing behaviors to enhance adolescent development, particularly in the context of the COVID-19 pandemic.

Autophagy inhibition and ferroptosis activation during atherosclerosis: Hypoxia-inducible factor 1α inhibitor PX-478 alleviates atherosclerosis by inducing autophagy and suppressing ferroptosis in macrophages.

OBJECTIVE: To elucidate the key regulator responsible for autophagy and ferroptosis, and if specific pharmacological inhibitor of upregulated gene exerted the pro-autophagic and anti-ferroptotic effect on macrophage to alleviate the atherosclerosis. METHODS: Autophagy and ferroptosis were evaluated in atherosclerotic lesions and THP-1 macrophages exposed to ox-LDL. Autophagy/ferroptosis-related differentially expressed genes (DEGs) in atherosclerosis were identified by bioinformatic analysis of GSE97210 dataset, and were validated in atherosclerotic cells and tissues. The efficacy and mechanism of pharmacological inhibition of the validated DEGs on alleviating atherosclerosis were explored in vivo and in vitro. RESULTS: Atherosclerotic lesions were characterized by autophagy inhibition and ferroptosis activation in macrophages. The crosslink between autophagy and ferroptosis were demonstrated. Ox-LDL induced THP-1 macrophage foam cell formation, autophagy dysfunction, and ferroptosis occurrence. Rapamycin ameliorated and, conversely, erastin deteriorated the effect of ox-LDL on THP-1 macrophages. Eleven autophagy/ferroptosis-related DEGs were identified in atherosclerosis vs. normal. The up-regulated expression of HIF-1α was verified in atherosclerotic lesions and THP-1 macrophages induced by ox-LDL. HIF-1α inhibitor PX-478 restored autophagy function, depressed ferroptosis, and reduced lipid accumulation in ox-LDL induced THP-1 macrophage. Autophagy inhibitor 3-MA obviously abrogated the pro-autophagic, anti-ferroptotic, and anti-atherosclerotic effects of PX-478. PX-478 treatment down-regulated HIF-1α expression and reduced atherosclerotic plaques in the mice model. CONCLUSIONS: Autophagy is inhibited, ferroptosis is activated, and crosslink occurs between autophagy and ferroptosis during atherosclerosis. HIF-1α, an upregulated DEG between atherosclerosis and normal, co-regulates autophagy and ferroptosis. HIF-1α inhibitor PX-478 attenuates foam cell formation and lessens atherosclerosis by enhancing autophagy and depressing ferroptosis in macrophages.

Bamboo Nanocellulose/Montmorillonite Nanosheets/Polyethyleneimine Gel Adsorbent for Methylene Blue and Cu(II) Removal from Aqueous Solutions.

In recent years, the scarcity of pure water resources has received a lot of attention from society because of the increasing amount of pollution from industrial waste. It is very important to use low-cost adsorbents with high-adsorption performance to reduce water pollution. In this work, a gel adsorbent with a high-adsorption performance on methylene blue (MB) and Cu(II) was prepared from bamboo nanocellulose (BCNF) (derived from waste bamboo paper) and montmorillonite nanosheet (MMTNS) cross-linked by polyethyleneimine (PEI). The resulting gel adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (SEM), X-ray photoelectron spectroscopic (XPS), etc. The results indicated that the MB and Cu(II) adsorption capacities of the resulting gel adsorbent increased with the solution pH, contact time, initial concentration, and temperature before equilibrium. The adsorption processes of MB and Cu(II) fitted well with the fractal-like pseudo-second-order model. The maximal adsorption capacities on MB and Cu(II) calculated by the Sips model were 361.9 and 254.6 mg/g, respectively. The removal of MB and Cu(II) from aqueous solutions mainly included electrostatic attraction, ion exchange, hydrogen bonding interaction, etc. These results suggest that the resulting gel adsorbent is an ideal material for the removal of MB and Cu(II) from aqueous solutions.

Management Strategy and Radiologic Outcomes of Symptomatic Spontaneous Isolated Superior Mesenteric Artery Dissection Based on Angiographic Classification: The Follow-Up Experience in a Single Center.

PURPOSE: To investigate the demographics, clinical features, radiologic measurement, treatment, and outcomes of symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD) according to computed tomography (CT) classification. METHODS: This retrospective study included 201 patients diagnosed with symptomatic SISMAD from November 2014 to December 2020. Symptomatic spontaneous isolated superior mesenteric artery dissection was categorized into four types based on CT images by Yun's angiographic classification. Their clinical characteristics, images features, treatment methods, and radiological outcomes were comparatively analyzed by CT angiographic types. RESULTS: SISMADs were categorized into type I (13.9%) patent false lumen (FL) with both entry and re-entry; type IIa (37.3%), blind pouch of FL; type IIb (43.3%), thrombosed FL; and type III (5.5%), and the occlusion of superior mesenteric artery (SMA). Type IIb, the most common SISMAD, showed the largest true lumen (TL) residual diameter and the lowest percentage of TL stenosis. Type III positioned most proximally to SMA origin and had the maximum dissection length. Symptomatic spontaneous isolated superior mesenteric artery dissections underwent conservative (75.1%), endovascular (22.4%), and surgical (2.5%) treatment. Conservative treatment was more frequent in type I (85.7%) and type IIb (83.9%) than in type IIa (65.3%) and type III (45.5%). Endovascular intervention was more commonly utilized in type IIa (32.0%) and type III (36.4%) than in type I (14.3%) and type IIb (14.9%). Conservative patients achieved FL vanishment/shrinkage (57.8%), stabilization (26.6%), and enlargement (15.6%). After conservative treatment, type I showed angiographic FL stabilization; type IIa achieved FL shrinkage (48.1%), stabilization (22.2%), and enlargement (29.6%); type IIb exhibited FL vanishment/shrinkage (92.0%) and enlargement (8.0%). Cumulative rate of stent patency was 92.3% during 6-year follow-up. CONCLUSIONS: Conservative management with close follow-up is initially provided especially for types I and IIb. Morphological stabilization is more frequent in type I of patent FL with entry and re-entry. False lumen vanishment or shrinkage was more likely to occur in type IIb due to the thrombus absorption. Endovascular intervention has excellent long-term in-stent patency and is predominantly utilized in types IIa and III. Blood flow sustained into a blind-ending FL causes the TL compression and stenosis in type IIa. Type III with the occlusion of SMA has the high risk of bowel ischemia. CLINICAL IMPACT: According to Yun's angiographic classification of spontaneous isolated superior mesenteric artery dissection (SISMAD), type I (13.9%) has patent true and false lumen and the morphological pattern is maintained stable; type IIa (37.3%) possesses a patent blind-ending false lumen which might shrink, remain unchanged, or enlarge; and endovascular intervention is suggested when conservative treatment failed; type IIb (43.3%) recovers spontaneously due to the absorption of false lumen thrombus and conservative treatment is preferentially considered; type III (5.5%) with the occlusion of main trunk carries a high risk of bowel necrosis, early endovascular intervention is proposed, and open surgery might be necessary.

CXCR4+ Sorted Adipose-Derived Stem Cells Enhance Their Functional Benefits and Improve Cardiac Function after Myocardial Infarction.

Objective: The homing of adipose-derived stem cells (ASCs) to infarcted myocardium, which is important for improved cardiac function, has been investigated previously, but with poor efficiency. Substantial improvements in engraftments are required to optimize ASC treatment. Stromal derived factor-1α (SDF-1α) is upregulated early after MI, and its endogenous receptor, chemokine receptor 4 (CXCR4), is pivotal in stem cell survival, migration, and engraftment. We examined whether CXCR4+ ASCs enhance their efficacy of migration and engraftment posttransplantation and improve heart function following myocardial infarction (MI). Methods and Results: CXCR4+ ASC subpopulations were sorted by fluorescence-activated cell sorting. CXCR4+ sorted ASCs exhibited the stronger cell viability, the faster proliferation rate, and the better migration capability in comparison with unfractionated ASCs. CXCR4+ sorted ASCs secreted a higher level of angiogenic growth factors including VEGF, HGF, and IGF-1 relative to unfractionated ASCs. Fewer apoptotic cells under oxygen-glucose deprivation were detected in CXCR4+ sorted ASCs than in unfractionated ASCs. Osteogenic and angiogenic differentiation were more pronounced in CXCR4+ sorted ASCs than in unfractionated ASCs. At 3 days after acute MI, rats were randomly allocated to receive intramyocardial injection of cell culture medium, CXCR4+ sorted ASCs, and unfractionated ASCs. Left ventricular function was assessed echocardiographically 4 weeks thereafter. Explanted hearts were then processed for the immunofluorescence detection of survived cells, quantification of angiogenesis, and cell engraftment. CXCR4+ sorted ASCs more obviously engrafted into infarcted myocardium, more markedly inhibited collagen remodeling, and more effectively improved heart function and promoted capillary formation than did unfractionated ASCs. Conclusion: CXCR4+ sorted ASCs are superior to unfractionated ASCs due to better viability, faster proliferation, more cytokine secretion, and stronger migration. CXCR4+ sorted ASCs provide better curative benefits on MI than do unfractionated ASCs and can be efficiently harvested and purified from adipose tissue, they may serve as a promising candidate for MI.

Overexpression of integrin ß2 improves migration and engraftment of adipose-derived stem cells and augments angiogenesis in myocardial infarction.

Background: Adipose-derived stem cells (ASCs) hold a great promise for myocardial infarction, but therapeutic efficacy appears to be limited by their poor survival and engraftment. Integrins are transmembrane proteins known to regulate the biological behaviors of stem cells. Integrin ß2 (ITGB2) specifically binds to intercellular cell adhesion molecule-1 (ICAM-1), which is upregulated in infarcted myocardium. ASCs typically express an insufficient amount of ITGB2, and this may limit their homing and engraftment abilities. Methods: ASCs were lentivirally transduced to overexpress ITGB2. ITGB2 messenger RNA (mRNA) and protein expression were examined by quantitative polymerase chain reaction (PCR) and western blot. Cell viability, proliferation, and migration were assessed in vitro. Adipogenic and osteogenic differentiation were induced, and the mRNA expressions of specific differentiation markers were quantified by PCR. ICAM-1 expression in the infarcted myocardium was quantified at 3 and 7 days after myocardial infarction. ITGB2-transfected ASCs (ITGB2-ASCs), control ASCs (CTRL-ASCs), and phosphate-buffered saline (PBS) were intramyocardially injected into the peri-infarct region at 3 days after coronary ligation. Four weeks after transplantation, myocardial blood perfusion was measured by 13N·NH3·H2O2 positron emission tomography (PET)/computed tomography (CT). Explanted hearts were then processed for the measurement of capillary density, the quantification of survived green fluorescent protein (GFP+) ASCs, and the identification of ASCs coexpressing angiogenic growth factors. Results: ICAM-1 expression peaked at 3 days after myocardial infarction and remained elevated over the remote normal myocardium at 7 days after myocardial infarction. ITGB2-ASCs displayed a significant increase in cell viability, proliferation rate, and migration index when compared with CTRL-ASCs. Adipogenic and osteogenic differentiation were more enhanced in ITGB2-ASCs than in CTRL-ASCs. Four weeks after transplantation, surviving GFP+ ASCs were significantly increased, ASCs expressing angiogenic growth factors were more pronounced, capillary density was substantially enlarged, and myocardial blood perfusion was markedly improved in the hearts that received ITGB2-ASCs implantation when compared to those that underwent CTRL-ASC treatment. Conclusions: ITGB2 overexpression of ASCs enhanced cell viability, proliferation, and migration and induced differentiation in vitro. ITGB2 overexpression significantly improved the survival and engraftment of ASCs into infarcted myocardium via ITGB2/ICAM-1 interaction, augmented angiogenesis, and ultimately improved blood perfusion in infarcted myocardium.

Relationship Between Morphological Remodeling and Angiographic Types of Spontaneous Isolated Superior Mesenteric Artery Dissection After Conservative Management: Determinant Affecting Serial Radiologic Courses.

Objective: To monitor the radiological courses of symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD) after conservation, clarify the relationship between its morphological change and initial imaging classification, and identify these factors that affect dissection remodeling. Methods: Eighty-nine conservative patients with SISMAD who underwent periodic follow-up of computed tomography angiography (CTA) were enrolled. Initial morphologic classification, imaging features and dissection remodeling were analyzed retrospectively. Logistic regression was used to identify predictors for remodeling. Receiver operating characteristics were performed for cutoff threshold. Results: Zerbib classification was adapted and initial CT appearance divided eighty-nine patients into: type I (15.7%), patent false lumen (FL) with both entry and re-entry; type II (37.1%), "cul-de-sac" shaped FL without re-entry; type III (27.0%), thrombosed FL with ulcer-like-projection (ULP); type IV (18%), intramural hematoma; type V (0%), dissecting aneurysm; and type VI (2.2%), total or partial occlusion of superior mesenteric artery (SMA). Follow-up CTA revealed complete remodeling (33.7%), partial remodeling (16.9%), no change (25.8%), type change (13.5%) and dissection progression (10.1%). There was no dissection-related mortality. Type I (92.9%) sustained patent FL and no angiographic change. Type II showed partial remodeling (42.4%), no change (27.3%) and dissection progression (27.3%), and the length of FL enhancement positively predicted dissection progression with the cutoff of 40.3 millimeters. Type III achieved complete remodeling (58.3%) or evolved into type II (41.7%), and the distance between SMA orifice and ULP negatively predicted type change with the cutoff of 23.5 millimeters. Type IV (87.5%) achieved complete remodeling due to hematoma absorption. One patient underwent stent placement for the evolution of ULP into an enlarged blind-ending FL 2 months after conservation. Conclusion: After conservation, patent FL with a distal re-entry is no morphological change, FL thrombosis tends to be resolved, and the "cul-de-sac" shaped FL without re-entry is partially shortened, no change or progressively dilated. FL enhancement length ≥ 40.3 millimeters is a predictor for the blinding-end FL enlargement. Thrombosed FL with ULP evolves into a patent "cul-de-sac" shaped FL when the distance between SMA orifice to ULP is less than 23.5 millimeters. A careful follow-up is necessary for the lesions with demonstrated predictors.

Multiple Aneurysms of the Subclavian-Axillary, Abdominal Aortoiliac, Lower Extremity, and Coronary Arteries in A Pediatric Patient of Takayasu Arteritis.

Takayasu arteritis is a chronic inflammatory vasculitis affecting mainly the aorta and its branches. Stenosis and occlusion of the involved vessels usually develop; however, their dilation and aneurysmal formation are extremely rare. Although aneurysmal disease has been reported in adults with Takayasu arteritis, it is a rare entity in children. The present report described an 11-year-old male found to have the subclavian-axillary, abdominal aortoiliac, lower extremity artery aneurysms with mural thrombi. Aneurysms were also found at the proximal and middle segments of the right coronary artery. The patient was conservatively treated with corticosteroid in addition to antiplatelet and anticoagulation agents.

Remodeling of Aortic Configuration and Abdominal Aortic Branch Perfusion After Endovascular Repair of Acute Type B Aortic Dissection: A Computed Tomographic Angiography Follow-Up.

Background: Thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) induces false lumen (FL) thrombosis, promotes favorable aortic remodeling, and makes an impact on abdominal aortic branch perfusion patterns. However, little is known about the long-term fate of aortic remodeling and abdominal aortic branch perfusion after TEVAR for TBAD and the effect of FL thrombosis status on these changes. Materials and methods: Between January 2014 and May 2021, 59 enrolled patients with acute TBAD were treated with TEVAR and had post-operative or follow-up images. Pre-operative, post-operative, and latest follow-up CT angiography (CTA) data were analyzed for the largest diameter of true lumen (TL), FL, and transaorta and for the FL thrombosis status on the stented thoracic aorta, unstented thoracic aorta, and abdominal aorta. Abdominal aorta perfusion patterns were characterized. Results: The mean follow-up period was 17.1 months. In the stented thoracic aorta, average TL diameters increased, average FL diameters decreased, and average transaortic diameters did not change; 82.6% of the patients had either a stable or shrinking transaortic size and 87% of the patients achieved total FL thrombosis. In the unstented thoracic aorta, average TL diameters increased, transaortic growth and no changes occurred in 39.1 and 45.7% of the patients, respectively, and complete FL thrombosis was present in 50% of the patients. In the abdominal aorta, average FL and transaortic diameters increased, aorta was expanded in 52.2% of the patients, and FL remained patent in 65.2% of the patients. Of the 354 branches, 37 branches (10.5%) exhibited changes in perfusion patterns, 22 branches (6.2%) demonstrated an increased TL perfusion, and 15 branches (4.2%) had an increased FL contribution. Compared with patent or partially thrombosed FL, complete FL thrombosis was accompanied by a bigger decrease in FL diameters, a larger increase in TL diameters, and a higher percentage of abdominal branch TL perfusion. Conclusions: In majority of the patients, TEVAR stabilized the size of the stented thoracic aorta, namely TL expansion and FL obliteration. However, abdominal aortic FL remained patent FL, and it was expanded with the resultant transaortic growth over a long follow-up period. Abdominal aortic branch perfusion patterns remained largely stable after TEVAR. The failure to achieve FL thrombosis negatively affects the remodeling of a contagious abdominal aortic dissection.

Bamboo-Based Biofoam Adsorbents for the Adsorption of Cationic Pollutants in Wastewater: Methylene Blue and Cu(II).

Human health is being threatened by cationic pollutants in wastewater, for example, methylene blue (MB) and Cu(II). Our research team successfully fabricated biofoam adsorbents from recycled bamboo waste that removed cationic pollutants via introducing bamboo fiber sources, i.e., bamboo fiber, bamboo α-cellulose fiber, and bamboo nanocellulose fiber, into a polyurethane (PU) foam matrix. The biofoam adsorbent with 1 g of nanocellulose (PUN1) presented high removal efficiencies for MB (95.52%) and Cu(II) (100%) in low cationic pollutant concentration aqueous solutions. The biofoam adsorbent with 1 g of bamboo fiber (PUB1) also displayed excellent removal efficiency for MB (98.61%) at pH 11. Meanwhile, 100% removal of Cu(II) was obtained by PUB1 at pH 7 (initial content = 15 mg/L). Furthermore, the PUN1 sample had excellent reusability, evidenced by 61.25% removal of MB after five adsorption-desorption cycles, suggesting that PUN1 is a promising renewable adsorbent for cationic pollutants. In addition, PUB1 is a low-cost adsorbent with good adsorption efficiencies for MB in weak alkaline solutions and Cu(II) in neutral aqueous solutions.
