Summary: The novel calcium oxalate/calcium silicate hydrate (Ca-Ox/C-S-H) adsorbent synthesized from blast furnace slag (BFS) exhibits superior maximum uptake capacities for Pb2+ (2117 mg g-1) and Cd2+ (1083 mg g-1). The adsorption mechanism involves ion exchange and equilibration time for Pb2+ is 10 minutes at a solid-to-liquid ratio of 1.0 g L-1, in accordance with both pseudo-first- and pseudo-second-order reaction kinetics models. The adsorption isotherms of Ca-Ox/C-S-H for both metal ions also fit the Sips model well. The adsorbent shows high selectivity towards Pb2+ among various heavy metals and retains high adsorption capacity even after being recycled multiple times.

Summary: The study found that silica nanoparticles (SNPs) promote the hydration of tricalcium aluminate (C3A) at the early stage of hydration, but subsequently lead to a retardation in the reaction. This retardation may be attributed to the surface coverage of C3A grains by calcium silicate hydrate (C-S-H) and calcium alumina silicate hydrate (C-A-S-H).

Summary: A monolithic cryogel based on starch and calcium silicate hydrate (Cry-CSH) was used as a phosphate adsorbent in a continuous flow system for the first time. The adsorption efficiency was influenced by flow rate, initial phosphate concentration, and adsorbent height. Increasing flow rate and initial concentration decreased the adsorbed phosphate quantity, but increasing adsorbent height greatly improved the column's performance. The continuous flow system using the monolithic Cry-CSH column achieved an excellent total adsorption of 94.61% for phosphate removal from wastewater.

Summary: The formation of siliceous-hydrogarnet (Si-hydrogarnet) and the stability of katoite (C(3)AH(6)) in the tricalcium aluminate (C(3)A) system in the presence of silica nanoparticles (n-SiO2) were investigated in this study. The results showed that the presence of n-SiO2 destabilizes the katoite phase and promotes the formation of C-S-H/C-A-S-H and Si-hydrogarnet during hydration. These findings are important for the performance and durability of materials.

Summary: The individual effects of nano hydrozincite and witherite on the performance of alkali-activated slag (AAS) were evaluated. It was found that nano hydrozincite caused a retardation effect on the early hydration rate of AAS, while witherite demonstrated an acceleration effect. These effects were due to the formation of zinc and barium hydroxides through alkali-dissolution. Changes in the Ca/Si ratio within calcium silicate hydrate were observed in both AAS-nHZ and AAS-nW mixtures. The proposed approach successfully produced hardened materials with high mechanical performance using low nanomineral and NaOH contents.

Summary: This study identified 372 differentially expressed circRNAs in peripheral blood mononuclear cells (PBMCs) of children with asthma. Among them, a circRNA called circS100A11 was highly expressed in monocytes and significantly upregulated in children with asthma. Further experiments demonstrated that circS100A11 promoted M2a macrophage activation by enhancing translation of its host gene, S100A11, and exacerbated lung inflammation in a mouse model of asthma. The study also found that circS100A11 competitively bound to CAPRIN1 to promote S100A11 translation, thereby enhancing M2a macrophage activation.

Summary: In this paper, a new run-time monitoring technique is proposed to detect hardware Trojans (HT) on working field-programmable gate array (FPGA), which can enhance the hardware security of IoT devices. The technique places multiple temperature sensors on FPGA and collects their values at each time interval. A predictive model is constructed to estimate the real-time distribution of sensor frequency. If the difference between the predicted value and the real one exceeds a dynamically updated threshold, an HT activation is reported. The experiment results demonstrate that the technique achieves high detection accuracy (>= 98%), low false negative ratio (<= 1.5%), and zero false positive ratio under various FPGA HT benchmarks.

Summary: Spatial transcriptomes were used to study the transcriptomic landscape in the posterior intestine of Sebastes schlegelii following Edwardsiella piscicida infection. A molecular regionalization of the posterior intestine was observed in the healthy condition. After bacterial infection, immune-related genes were predominantly found in the mucosa layer. The expression of regeneration-related genes suggested the constant proliferation of new cells in response to pathogen invasion, while increasing microbiota communities indicated their role in maintaining intestinal integrity and shaping the mucosal immune system.

Summary: This paper focuses on the Largos of the Macau Peninsula and categorizes their main functions as serving the community, facilitating traffic, and promoting religious culture through historical combing and field research. A spatial syntactic theory is applied to establish a model, using three syntactic parameters - synergy, integration, and choice - to interpret the analysis results. Based on the syntactic parameters, the results are divided into four categories, and improvement strategies are proposed for the selected spaces that require enhancements. Taking Macau's Largos as an example, this paper aims to provide a reference for the effective renewal of urban micro-spaces and small public spaces by applying space syntax analysis.

Summary: Total parenteral nutrition (TPN) can cause glucose metabolism disorders by altering the gut microbiota and its metabolites, leading to insulin resistance and an increased risk of complications. Decreased levels of Lactobacillaceae and indole-3-acetic acid (IAA) are associated with these complications, while the abundance of Lactobacillaceae and IAA is negatively correlated with insulin resistance and serum lipopolysaccharide levels. IAA activates the aryl hydrocarbon receptor and increases glucagon-like peptide-1 secretion, preventing TPN-induced glucose metabolism disorders in mice.

Summary: With aging, abnormalities during oocyte meiosis become more prevalent, and the mechanisms of aging-related oocyte aneuploidy are not fully understood. This study reveals that disruptions in the mevalonate (MVA) pathway in granulosa cells (GCs) contribute to meiotic defects and aneuploidy in oocytes. Supplementation with MVA metabolites improves oocyte quality, suggesting a potential therapeutic strategy for promoting female reproductive longevity.

Summary: Historically, deuteration reactions were mainly used for mechanistic studies, but their pharmacological importance is now recognized. Efforts have been made to meet the urgent need for deuteration tools since the approval of the first deuterated drug for Huntington's disease. Current deuteration strategies involving reversible H/D exchange have limitations in functional group tolerance and deuterium content. In this study, a ruthenium-catalyzed deoxygenative deuteration of ketones was developed, allowing regiospecific deuteration with high deuterium content.

Summary: Recently, the photochemistry of Electron Donor-Acceptor (EDA) complexes using electron donors as catalytic agents has gained interest in the field of catalysis. This methodology allows for the separation of electron transfer from the bond-forming event. In this study, an EDA complex between triarylamines and alpha-perfluorosulfonylpropiophenone reagents was discovered. It catalyzes C-H perfluoroalkylation of arenes and heteroarenes under visible light irradiation in pH- and redox-neutral conditions. The mechanism of this reaction was elucidated through a detailed photophysical characterization of the EDA complex, triarylamine radical cation, and its turnover event.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
