Published: August 2024

AbstractSolar‐to‐hydrogen (STH) is emerging as a promising approach for energy storage and conversion to contribute to carbon neutrality. The lack of efficient catalysts and sustainable reaction systems is stimulating the fast development of photothermal hydrogen production based on floating carriers to achieve unprecedented STH efficiency. This technology involves three major components: floating carriers with hierarchically porous structures, photothermal materials for solar‐to‐heat conversion and photocatalysts for hydrogen production. Under solar irradiation, the floating photothermal system realizes steam generation which quickly diffuses to the active site for sustainable hydrogen generation with the assistance of a hierarchically porous structure. Additionally, this technology is endowed with advantages in the high utilization of solar energy and catalyst retention, making it suitable for various scenarios, including domestic water supply, wastewater treatment, and desalination. A comprehensive overview of the photothermal hydrogen production system is present due to the economic feasibility for industrial application. The in‐depth mechanism of a floating photothermal system, including the solar‐to‐heat effect, steam diffusion, and triple‐phase interaction are highlighted by elucidating the logical relationship among buoyant carriers, photothermal materials, and catalysts for hydrogen production. Finally, the challenges and new opportunities facing current photothermal catalytic hydrogen production systems are analyzed.

Abstractα‐SnWO4 is a promising semiconductor for solar water splitting, however, its performance is limited by weak water oxidation and poor charge transfer. In this study, we employ a vapor deposition method to uniformly implement a carbon layer onto the surface of SnWO4 coupled with a CoNiP cocatalyst, successfully constructing the integrated CoNiP/C/SnWO4 film photoanode and alleviating the oxidation of Sn2+ when loading electrocatalyst. Incorporating the carbon layer enhances the interface charge conduction behavior between the SnWO4 substrate and the CoNiP cocatalyst, thereby mitigating charge recombination. The synergistic interplay between the carbon layer and CoNiP leads to a remarkable achievement, as evidenced by the photocurrent of 1.72 mA cm−2 (1.23 V vs. RHE) observed for SnWO4 film measured in 0.2 M potassium phosphate buffer solution. In this work, we demonstrate the viability of tailoring SnWO4 photoanode and provide valuable insights for prospective advancements in modifying SnWO4 photoanode.

Published: August 2024

AbstractIn comparison with the well‐established allylic additions to C=O, C=N, and C=C double bonds, the dearomative allylic addition to arene π‐systems is heavily underdeveloped due to the severe challenge in breaking aromatic resonance stabilization. Herein, we disclose a general and efficient dearomative allylic addition to chromium‐bound arenes using allylsilanes as the pronucleophiles, thus affording convenient access to allyl‐functionalized 1,3‐cyclohexadiene building blocks. With commercially available deuterium sources, the versatility of this strategy further enables an arene dearomative 1,2‐deuteroallylation with a high level of deuterium incorporation. Finally, a preliminary try on the asymmetric dearomative hydroallylation based on a chiral auxiliary strategy is described.

ABSTRACTDespite being a cutting‐edge technology, the proton exchange membrane fuel cell (PEMFC) generates a lot of heat as it works, which makes it wasteful with energy. In order to enhance energy efficiency via waste heat recovery, we provide and analyze a novel integrated energy system that utilizes PEMFC and ORC technology. There are a lot of ways to put the waste heat from fuel cells (FCs) to good use, but the most efficient one is the organic Rankine cycle (ORC) with the right working fluid. This research aims to find the optimal way to use the waste heat of the FC by testing several working fluids. The optimal solution is derived using a genetic algorithm by monitoring the objective functions that characterize the system's overall performance as they vary across different system parameters. The results show that the proposed efficient integration achieves high energy and exergy efficiency levels and achieves rates of total cost and environmental impact that are within acceptable limits. Since the fuel usage element's content significantly affects the system indicators in several ways, the results also demonstrate that it is quite relevant. Since the exergo‐environmental metric and the exergy efficiency meter are always moving in different directions, choosing a design condition that meets several requirements is crucial. According to the results, fuel cells had the highest irreversibility rate at 12.2, making them the most energy‐conserving piece of machinery.

AbstractChemical analysis showed that pH, b* values, myosin turbidity, carbonyl content, and surface hydrophobicity elevated in hooked, trawl‐net, and radar‐net hairtail (Trichiurus haumela, HH, TH, and RH) muscles with the prolonged cryopreservation time (‐18℃, 120 d). In contrast, L*, a* values, textural properties, and myosin solubility existed decreasing trends. Microstructural results showed that freezing resulted in disordered myofibrils, decreased collagen fibers, widened myofibrillar space, and increased fragmentation in hairtail muscles. Furthermore, volatile flavor analysis suggested that aldehydes, ketones, alcohols, and amines were the key factors for the overall flavor formation in hairtails during cold storage. Pearson correlation coefficient analysis revealed that the color, texture, and protein oxidation had close correlations with VOCs. Among the three different kinds of hairtail, fresh RH fillets exhibited an attractive aroma with high economic value, long‐term frozen TH muscle tissues were prone to deterioration in texture, microstructure, and flavor, and the HH samples presented stable quality characteristics and storage performance.

AbstractThe objective was to develop an active chitosan‐based coating and to evaluate its effect on the shelf life and microbial safety of bread. Bacterial cellulose nanofibers (BCNF) and various levels (0.5%, 1%, and 2%) of silver nanoparticles (AgNPs) were in the chitosan (CS) film. Characterization of films was determined by analyzing WVP, ultraviolet barrier, and opacity as well as FTIR, XRD, DSC, TGA, and SEM. The water vapor permeability (WVP) of CS was remarkably (p < .05) decreased from 3.75 × 10−10 to 0.85 × 10−10 g/smPa when filled with BCNF and 2% AgNPs. Thermal and structural properties were enhanced in nanoparticle‐included films. Applying CS/BCNF/AgNPs coatings for bread samples demonstrated a significant improvement in moisture retention and a decrease in the hardness (from 10.2 to 7.05 N for CS and CS/BCNF/1% AgNPs coated samples, respectively). Moreover, microbial shelf life of bread sample increased from 5 to 38 days after packaging with CS/BCNF/2% AgNPs film. After a storage period of 15 days at 25°C, no fungal growth was detected in bread samples which were coated with nanocomposite suspensions containing 1% and 2% AgNPs. However, at the same condition, yeast and mold counts was 7.91 log CFU/g for control sample. In conclusion, the CS/BCNF/2% AgNPs film might have the potential for use as active packaging of bread.

Published: August 2024

AbstractLow‐dose antiangiogenic therapies have demonstrated the ability to enhance normalization of tumor vessels, consequently improving hypoxia levels, drug delivery, and promoting anticancer immune responses. Mast cells have been identified as contributors to resistance against antiangiogenic therapy and facilitators of abnormal neoangiogenesis. In this study, we demonstrate that by simultaneously targeting intratumoral mast cells with Imatinib and administering low‐dose anti‐VEGFR2 therapy, antitumor efficacy can be enhanced in preclinical models. Thus, combinatory treatment overcomes therapy resistance, while concurrently promoting tumor vessel normalization. Notably, histomorphometric analysis of tumor sections revealed that vessel perfusion could be improved through mast cell inhibition and, despite a significantly reduced microvessel density, the combination treatment did not result in elevated tumor hypoxia levels compared to anti‐VEGFR2 therapy alone. Short‐term Imatinib application effectively increased antitumor efficacy, and by prolonging the application of Imatinib tumor vessel normalization was additionally improved. The combination of mast cell depletion and antiangiogenic treatments has not been investigated in detail and promises to help overcoming therapy resistance. Further studies will be required to explore their impact on other treatment approaches, and subsequently to validate these findings in a clinical setting.

AbstractAntibodies that target the tumor microenvironment can be used to deliver pro‐inflammatory payloads, such as cytokines. Cytokines are small proteins able to modulate the activity of the immune system, and antibody–cytokine fusion proteins have been tested in preclinical and clinical settings. In this study, we describe Tripokin, a novel multi‐specific fusion protein that combines interleukin‐2 and a single amino acid mutant of tumor necrosis factor. The two pro‐inflammatory payloads were fused to the L19 antibody, a clinical‐grade antibody against the extradomain B of fibronectin. The human payloads were used for clinical applications, while the corresponding murine cytokines were used for preclinical studies. The resulting fusion proteins were produced in mammalian cells and purified to homogeneity. The murine Tripokin product was well tolerated in tumor‐bearing mice at three doses of 30 μg in a 2‐day interval and promoted rapid tumor eradication in murine models, more efficiently than single‐agent immunocytokines. Tripokin induced rapid tumor necrosis and stimulated a robust immune response, impacting innate and adaptive immune pathways. In addition, the combination with immune checkpoint inhibitors further boosted the therapeutic efficacy of our molecule. Tripokin represents a promising clinical candidate for the simultaneous delivery of interleukin‐2 and tumor necrosis factor to neoplastic sites.

AbstractObjectiveThe aim of the present study was to investigate the incidence of intrahepatic cholestasis of pregnancy (ICP) as well as neonatal outcomes between conception via in vitro fertilization (IVF) compared with spontaneous conception (SC) and screen the risk factors of ICP in IVF.MethodsThis retrospective cohort study included 4467 puerperae who conceived via IVF, and 28 336 puerperae who conceived spontaneously and linked the information from neonates. The general linear model (GLM), multivariate logistic regression analysis, a forest plot, and nomogram were used to assess impact factors and risk prediction.ResultsLogistic analysis adjusted for confounders revealed significant differences in the ICP rate of singleton delivery (4.24% vs 3.41%, adjusted OR [aOR] = 1.26; 95% confidence interval [CI] 1.03–1.53, P = 0.025) and in groups with total bile acids (TBA) ≥40 and <100 μmol/L (14.77% vs 10.39%, aOR = 1.31; 95% CI: 1.06–1.63, P = 0.023) between IVF and SC. When we divided newborns into singleton and twins delivery, the GLM revealed a higher rate with Apgar score <7 (13.44% vs 3.87%, aOR = 3.85; 95% CI: 2.07–7.17, P < 0.001) and fetal distress for IVF in comparison with SC (19.32% vs 5.55%, OR = 3.48; 95% CI: 2.39–6.95, P < 0.001) in the singleton group. In multivariate logistic regression analysis, body mass index (BMI) (aOR = 1.29; P = 0.031), number of embryo transfers (ET) (single ET vs double ET, aOR = 2.82; P < 0.001), E2 level on the ET day (aOR = 2.79; P = 0.011), fresh ET which compared with frozen ET (FET) (aOR = 1.45; P = 0.014), embryo stage (cleavage embryo vs blastocyst, aOR = 1.75; P = 0.009) and severe ovarian hyperstimulation syndrome (OHSS) which compared with non‐OHSS (aOR = 3.73; P = 0.006) were independent predictors of ICP. These predictive factors in the logistic regression model were integrated into the nomogram (C‐index = 0.735; 95% CI: 0.702–0.764); for each patient, higher total points indicated a higher risk of ICP.ConclusionWe observed that the ICP rate of singleton delivery was higher in IVF than in SC. In ICP patients, there were higher rates of neonatal Apgar score <7 and fetal distress in IVF than SC and found the predictors of ICP in IVF.

IntroductionHypoglycemia occasionally develops after the resection of pheochromocytoma due to decreased catecholamine secretion. The unique glucose metabolism in dialysis patients may potentially affect postoperative hypoglycemia, although few reports have focused on this issue.Case presentationA 47‐year‐old woman who had chronic renal failure under hemodialysis was diagnosed with right pheochromocytoma and underwent an adrenalectomy. Three hours after surgery, she experienced symptomatic hypoglycemia, which was repeated until postoperative day 3. Continuous glucose infusion was required until postoperative day 8 and asymptomatic hypoglycemia was repeated until postoperative day 11.ConclusionIn hemodialysis patients, more careful management of hypoglycemia may be required after the resection of pheochromocytoma compared with non‐hemodialysis patients.

Experimentelle Untersuchungen über die infraspezifische Struktur von Chenopodium album L. sowie: Untersuchungen an Chenopodium suecicum J. Murr
Authors: Jüttersonke Barbara , Arlt Klaus 
Published: August 2024

ZusammenfassungDie vorgestellte Bearbeitung ergab sich aus der Notwendigkeit, eine praktisch anwendbare Taxonomie für eine erfolgreiche Agro‐Ökosystem‐Modellierung sowie für die Lösung von Problemen der Erforschung und Bekämpfung herbizidresistenter Unkräuter zu schaffen. Gegenstand der Untersuchungen war das Taxon Chenopodium album L. ssp. album var. album (sensu Aellen 1960). Durch mehrjährige Kulturversuche mit Nachkommenschaften ausgewählter Herkünfte, die hauptsächlich in der DDR gesammelt wurden, konnte die genetische Stabilität wichtiger Merkmale und deren Modifizierbarkeit durch Umweltfaktoren bewertet werden. Die Infloreszenzformen sind relativ stabil; auch unter differenzierten Temperatur‐ und Tageslängenbehandlungen wurden ihre Grundmuster nicht wesentlich verändert. Sie wurden daher als Basismerkmale für ein neues System verwendet, das geeignet ist, die Formenvielfalt des bearbeiteten Taxons hierarchisch zu ordnen und Beziehungen zwischen den Taxa zu zeigen. Den beschriebenen Formen und Subformen sind die Subvarietäten album und cymigerum übergeordnet. Untersuchungen über die Variabilität des Ch. suecicum J. Murr ergaben ebenfalls signifikante Unterschiede, die aber eine intensivere taxonomische Bearbeitung nicht ermöglichten. Erhebungen über die Verbreitung der beschriebenen Taxa des Ch. album var. album sowie des Ch. suecicum zeigten, daß Bindungen einiger Taxa an bestimmte Standorttypen, Klimagebiete und Kulturen bestehen.

Published: August 2024

SummarySeeds of 200 species of 17 angiospermic families were examined for the presence of alkaloids, cellulose, fats and oils, inulin, protein, starch granules and tannins.Alkaloids, cellulose, fats and oils, inulin, protein and tannins are found to be of sporadic occurrence in taxa studied. Cellulose, fats and oils and inulin were found to be present in all taxa studied. Of the 200 taxa studied, only 17 taxa belonging to 2 families (Caryophyllaceae, Leguminosae) are found to contain starch grains. However, the starch grains present are restricted to a particular type of habit, mainly the herbaceous habit. In general, arborescent taxa lack starch grains. 167 species distributed in 15 families investigated for ergastic substances are reported here for the first time.
