Abstract
It is necessary to examine the characteristics of the dissemination nodules to establish a therapeutic strategy for peritoneal dissemination from digestive malignancy. Ki-67 expression as a proliferation marker in peritoneal dissemination nodules was investigated. The subjects were 15 patients with gastrointestinal cancers who underwent resection of the primary tumor and disseminated nodules. The expression of Ki-67 in both primary tumor and peritoneal dissemination nodule from each patient was evaluated by immunohistochemistry. Ki-67 labeling index in the original tumor was higher than that in the disseminated nodule in 13 of 15 patients (P &lt; 0.0001). The mean value of Ki-67 labeling index was 42.2% in the 15 original tumors and 18.7% in the 15 disseminated nodules. Proliferative activity in the disseminated nodules was lower than that in the primary tumors. Further examination about characteristics of cancer dissemination is needed to treat patients with peritoneal metastasis.

Abstract
Peliosis hepatis is an extremely rare condition that may cause fatal hepatic hemorrhage and liver failure. We report a case of liver hemorrhage due to idiopathic peliosis hepatis. A 60-year-old woman was admitted to our hospital with slight right hypochondriac pain. She went into hemorrhagic shock, and computed tomography (CT) showed multiple low-density areas in the right liver with massive subcapsular blood collection. Selective transfemoral arteriography of the celiac artery revealed no signs of vascular malformation or tumor stain, but showed signs of pooling in the right posterior segmental artery. The artery was embolized with particles of gelatin sponge, and hemostatic control was successful. Although peliosis hepatis is extremely rare, the diagnosis is significant because of its urgent clinical status, and transarterial embolization is a useful and minimally invasive procedure for liver hemorrhage due to peliosis hepatis.

Abstract
Postoperative gastrointestinal bowel transit right after colorectal resection has not yet been clarified. Thirty patients with rectosigmoid cancer were treated in this pilot study. The nasogastric tube was removed on the first postoperative day. One Sitzmarks capsule was given to each patient on the second postoperative day. Abdominal X-rays were taken at 3, 6, 8, 24, 48, and 72 hours after capsule intake. Distribution of the remaining Sitzmarks capsules were counted on X-ray films to clarify postoperative gastrointestinal movement after bowel resection. All Sitzmarks capsules were observed in the stomach at 3 and 6 hours after capsule intake. At 8 hours (second postoperative day), the Sitzmarks capsules were distributed from the stomach to the small intestine. Sitzmarks capsules were distributed in the right side colon at 24 hours (third postoperative day) after intake. Although the main distribution was still in the right side colon, several patients had evacuations accompanied by the disappearance of the Sitzmarks capsules. In 50% of the patients, it took approximately 72 hours (fifth postoperative day) for the first defecation after intake of the capsules. However, the Sitzmarks capsules remained mainly in the right side colon. Eight hours after intake, the majority of the Sitzmarks capsules shifted to the small intestine. Therefore, medication or feeding should be safely possible starting on the second postoperative day. There was no particular impact of bowel resection on upper gastrointestinal transit in patients with rectosigmoid cancer.

AbstractMetal–organic cage‐based photo‐responsive supramolecular frameworks (PSMFs) with permanent porosity have gained attention for their modular properties, controllable functionality, and light‐induced reversible responsiveness. However, their high porosity and photo‐responsive efficiency are often compromised due to poor structural stability upon solvent removal, limiting their potential applications. Here, a solution to overcome this challenge by employing a surface polymerization strategy using isophorone diisocyanate (IDI) to stabilize PSMF (PCC‐20t) is presented. This approach results in the composite of PCC‐20t@PolyIDI, which preserves crystallinity and permanent high‐porosity while avoiding structural collapse commonly observed in highly porous supramolecular frameworks. Moreover, compared to activated PCC‐20t, PCC‐20t@PolyIDI exhibits an 18.6‐fold increase in specific surface area. Remarkably, the structural variability of PCC‐20t@PolyIDI can be observed in the photo‐regulation behavior of CO2 capacity under the irradiation of vis‐ and UV‐light, showing a 27.9% change in adsorption amount for CO2 which is significantly higher than that of the activated PCC‐20t with 7.0% for CO2. Grand Canonical Monte Carlo simulations demonstrate the light‐regulated adsorption performance is attributed to the configuration transformation of azobenzene from trans‐ to buckling state. The findings may pave the way for stabilizing high‐porosity materials to simultaneously meet demands for high‐porosity and photo‐responsive efficiency.

AbstractIn van der Waals magnets, the interplay between magneto‐excitonic coupling and optical phenomena opens avenues for directly probing magnetic ordering structures, manipulating excitonic properties through magnetic fields, and exploring quantum entanglement between electronic and magnetic states. Notably, NiPS3 stands out for its capacity to host spin‐entangled excitons, where the excitonic states are intricately tied with the material's spin configuration. Herein, it is experimentally showcased that the spin‐entangled excitons can be utilized for detecting the magnetic easy axis in Ni1‐xMnxPS3 (x = 0–0.1). The end members of this series exhibit distinct magnetic ordering patterns and easy axes: zigzag ordering with magnetic moments aligned along the a‐axis for NiPS3 versus Néel ordering with the out‐of‐plane easy axis for MnPS3. By combining angle‐resolved exciton photoluminescence with magnetic susceptibility measurements, it is observed that the magnetic easy axis rotates away from the local spin chain direction with increasing Mn content. Moreover, through a comprehensive thermal and substitution study, it is demonstrated that the energy and lifetime of spin‐entangled excitons are governed by two spin‐flip processes and are drastically influenced by disparate electronic states. These findings not only provide optical means to map out magnetic ordering structures but also offer insights into decoherence processes in spin‐exciton entangled states.

AbstractEngineering microstructural defects, like grain boundaries, offers superior control over transport properties in energy materials. However, technological advancement requires establishing microstructure‐property relations at the micron or finer scales, where most of these defects operate. Here, the first experimental evidence of thermal resistance for individual silicon grain boundaries, estimated with a Gibbs excess approach, is provided. Coincident site lattice boundaries exhibit uniform excess thermal resistance along the same boundary, but notable variations from one boundary to another. Boundaries associated with low interface energy generally exhibit lower resistances, aligning with theoretical expectations and previous simulations, but several exceptions are observed. Transmission electron microscopy reveals that factors like interface roughness and presence of nanotwinning can significantly alter the observed resistance, which ranges from ∼0 to up to ∼2.3 m2K/GW. In stark contrast, significantly larger and less uniform values ‐ from 5 to 30 m2K/GW ‐ are found for high‐angle boundaries in spark‐plasma‐sintered polycrystalline silicon. Further, finite element analysis suggests that boundary planes that strongly deviate from the sample vertical (beyond ∼45°) can show up to 3‐times larger excess resistance. Direct correlations of properties with individual defects enable the design of materials with superior thermal performance for applications in energy harvesting and heat management.

Published: July 2024

AbstractRare earth vanadates are promising for solar‐to‐fuel conversions, yet their photocatalytic efficiency is limited by the substantial recombination of photo‐generated carriers. Constructing heterojunctions is recognized as an effective approach to improving charge carrier separation in vanadates. Nonetheless, inefficient charge transfer often results from the poor quality of interfaces and non‐directional charge transfer within these heterojunctions. Herein, an S‐scheme AgInS2/CeVO4@Biocharx (AIS/CV@Cx) heterojunction photocatalyst is designed and synthesized through a straightforward freeze‐drying and calcination three‐step process, aimed at photocatalytic co‐production of xylonic acid and carbon monoxide (CO) from xylose. The AIS/CV@C2 heterojunction achieves an optimal yield of 67.74% for xylonic acid and a CO release of 29.76 µmol from xylose. The enhanced photocatalytic performance of the AIS/CV@C2 heterojunction is attributed to three key factors: I) the high‐quality interface and intimate contact within the AIS/CV@C2 heterojunction significantly reduce undesirable carriers recombination, II) the staggered band structures and directed carriers transfer in the AIS/CV@C2 heterojunction notably improve spatial carriers separation/migration, and III) the incorporation of biochar boosts the conductivity of the AIS/CV@C2 heterojunction. This work presents a straightforward yet effective method for fabricating vanadate heterojunctions, highlighting the importance of quality interfacial contact and directed charge transfer in amplifying photocatalytic performance.

AbstractThe hypoxic environment of deep tissue and the weak energy of microwave (MW) are still the major limitations of MW catalytic therapy. In this work, an MW‐responsive nano‐platform consisting of an Mn‐doped porphyrin metal–organic framework loaded with calcium peroxide (Mn0.1PCC) is designed to regulate the microenvironment of the injection site and enhance the generation of reactive oxygen species. The excellent MW absorbing properties of Mn0.1PCC improve the Fenton reaction between hydrogen peroxide formed by the hydrolysis of calcium peroxide and released Mn2+ generating more hydroxyl radicals under MW. This process does not consume the oxygen substrate and even produces oxygen to improve the hypoxic environment. Therefore, at a low and safe concentration (125 µg mL−1), the antibacterial rate of Mn0.1PCC against 4 × 108 CFU mL−1 of methicillin‐resistant Staphylococcus aureus (MRSA) after MW irradiation for 15 min is 99.71% ± 0.18%. Mn0.1PCC, upon exposure to MW, prevents the recurrence of bacterial infections and overcomes drug resistance by inhibiting quorum sensing and the two‐component system of MRSA. It can also induce macrophage M1 polarization, up‐regulate the pro‐inflammatory factor tumor necrosis factor‐α, and enhance the phagocytosis of macrophage to bacteria. This strategy provides insights into the development of high‐performance MW‐responsive nanocomposites for the treatment of infections in deep tissues.

AbstractFlexible zinc‐air batteries (FZABs) have emerged as a promising alternative to lithium‐ion batteries in flexible electronic devices due to the advantages of excellent mechanical properties, high energy density, and notable safety. However, the unclear causes of performance degradation and failure mechanisms of FZABs significantly impede their commercialization. Therefore, extensive research is needed to fully reveal the factors and mechanisms responsible for the performance decline of FZABs. In this review, the failure mechanisms of FZABs' key components, including the Zn anode, solid electrolyte, catalyst air cathode, and electrolyte/electrode interface are analyzed and discussed. To promote further research and development of FZABs, a series of challenges and corresponding strategies are summarized and analyzed. Finally, the future development of FZABs is envisioned. This paper aims to comprehensively elucidate the failure mechanisms of FZABs, guide the development of high‐performance FZABs, and thus promote their commercialization.

AbstractSodium metal battery is considered as one of the most promising energy storage/conversion devices due to their high energy density, and abundant sodium reserves. However, its development is hampered by the limited metallic utilization and detrimental sodium dendrite growth ascribed to the unstable, and fragile solid electrolyte interphase (SEI). Here, the high stable and modulus SEI is constructed with a component of a thin and dense layer of high Na‐ion conductive Na2SiO3. It is in situ formed by the reaction between sodium anode and fish‐skin structure separator, which exhibits a 3D porous polyvinylidene fluoride‐based framework embedded with thin and robust vermiculite sheets. The robust interphase cannot only suppress sodium dendrite growth but also enable high energy density with small interphase‐consumed Na ions in anode‐less batteries. Accordingly, the as‐assembled NaNi1/3Fe1/3Mn1/3O2//Na cell shows 83% capacity retention after 5000 cycles at a rate of 5 °C. Moreover, the proof‐of‐concept pouch cells deliver an energy density of 205 Wh kg−1 (based on the total mass of the battery), and high safety (not catching fire after punctured) under anode‐less condition (with a low negative/positive capacity ratio of ≈2.1).

AbstractTo date, the treatment options for metastatic and recurrent tongue squamous cell carcinoma (TSCC) remain limited due to the lack of effective drug targets and therapeutics. Here the identification of ICAM1 is reported as a TSCC target candidate for the development of antibody‐drug conjugate (ADC), an emerging class of targeted therapeutics. An unbiased and quantitative screening of a panel of 69 TSCC cell surface antigens is first performed that identifies ICAM1 as the most abundant hit. The overexpression level of ICAM1 is validated in 26 TSCC clinical specimens and four cell lines along with genomic information of 127 TSCC patients from the TCGA database. Based on this new target, the anti‐TSCC efficacy of ICAM1‐targeted ADCs featuring two payloads is evaluated of different mechanisms of action: MMAE and DXd. Both ADCs selectively and potently ablate TSCC tumors in the established SAS cell line and patient‐derived xenograft (PDX) models. The findings strongly support ICAM1 as a promising ADC target candidate for TSCC therapy.

AbstractSmall‐scale robots offer significant potential in minimally invasive medical procedures. Due to the nature of soft biological tissues, however, robots are exposed to complex environments with various challenges in locomotion, which is essential to overcome for useful medical tasks. A single mini‐robot often provides insufficient force on slippery biological surfaces to carry medical instruments, such as a fluid catheter or an electrical wire. Here, for the first time, a team of millirobots (TrainBot) is reported to generate around two times higher actuating force than a TrainBot unit by forming a convoy to collaboratively carry long and heavy cargos. The feet of each unit are optimized to increase the propulsive force around three times so that it can effectively crawl on slippery biological surfaces. A human‐scale permanent magnetic set‐up is developed to wirelessly actuate and control the TrainBot to transport heavy and lengthy loads through narrow biological lumens, such as the intestine and the bile duct. The first electrocauterization performed by the TrainBot is demonstrated to relieve a biliary obstruction and open a tunnel for fluid drainage and drug delivery. The developed technology sheds light on the collaborative strategy of small‐scale robots for future minimally invasive surgical procedures.

AbstractWährend Kunststoffe wie Polyethylenterephthalat (PET) bereits effizient durch die Aktivität von Hydrolasen abgebaut werden können, sind andere synthetische Polymere wie Polyurethane (PUs) und Polyamide (PAs) weitgehend resistent gegenüber einem biologischen Abbau. In dieser Studie lösten wir die erste Kristallstruktur der metagenomischen Urethanase UMG‐SP‐1, identifizierten hochflexible Loopregionen, die Reste des aktiven Zentrums enthalten, und untersuchten insgesamt 20 potenzielle Hotspots mittels Sättigungsmutagenese. Die durch Protein Engineering erzeugten Einzelmutanten wiesen eine fast 3‐ bzw. 8‐fach verbesserte Aktivität gegenüber hochstabilen N‐Arylurethan‐ und Amidbindungen auf. Darüber hinaus konnte die Freisetzung der entsprechenden Monomere aus einem thermoplastischen Polyester‐PU und einem PA (Nylon 6) durch die Aktivität einer einzigen, metagenomischen Urethanase nach kurzer Inkubationszeit nachgewiesen werden. Dadurch konnte das Hydrolyseprofil von UMG‐SP‐1 über die bekannten niedermolekularen Carbamate hinaus erweitert werden und erschließt so neue Möglichkeiten für den enzymatischen Abbau und das Recycling von Kunststoffen und Plastikabfällen. Damit unterstützt diese Studie Bemühungen um die Verbesserung einer Kreislaufwirtschaft für synthetische Polymere.

AbstractReaktionen von Diazoalkenen mit tert‐Butylphosphaalkin (tBuCP) und weißem Phosphor (P4) führen zu neuen Phosphorheterocyclen, 3H‐1,2,4‐Diazamonophospholen und 1,2,3,4‐Diazadiphospholen. Die erhaltenen Verbindungen sind seltene Beispiele für neutrale Heterophosphole. Der Bildungsmechanismus der formalen (3+2)‐Cycloadditionsprodukte wurde quantenchemisch berechnet und die elektronischen Strukturen analysiert. Die neuen Phosphole bilden strukturell vielfältige Koordinationsverbindungen mit Übergangsmetallen und Hauptgruppenelementen. Angesichts der wachsenden Anzahl stabiler Diazoalkene bietet diese Arbeit einen unmittelbaren Zugang zu neutralen Aza(di‐)phospholen als neue Ligandenklasse.
