Ficus benghalensis extract mediated green synthesis of silver nanoparticles, its optimization, characterization, computational studies, and its in vitro and in vivo biological potential
In this work, Silver (Ag) nanoparticles (NPs) were synthesized via green synthesis using Ficus benghalensis root extract (FBRE), serving as a capping and stabilizing agent. The synthesized Ag NPs were characterized via complementary characterization techniques, including SEM, XRD, EDS, UV-Vis, and FT-IR. SEM analysis revealed the fabrication of spherical NPs with an average size of 41.55 nm. A plasmon resonance peak was observed at 430 nm. FBRE effectively capped and stabilized the Ag NPs, ensuring their structural integrity over time, and is confirmed via FT-IR scan. DFT calculation revealed a thermodynamically and mechanically stable system. Moreover, optoelectronic properties confirmed the metallic behavior of Ag with a major contribution from 4d orbital near the fermi level and 5s orbital contribution to the conduction band with light absorption in the visible spectrum. Biological evaluations demonstrated significant enzyme inhibition. Ag NPs inhibited urease (80.76%), α-glucosidase (80.98%), carbonic anhydrase II (89.32%), and xanthine oxidase (49.9%), outperforming FBRE. In Vivo, Ag NPs exhibited dose-dependent analgesic (83.09% writhing inhibition at 10 mg/kg, similar to diclofenac) and sedative (16.09% locomotor reduction at 10 mg/kg) effects. Molecular docking confirmed strong enzyme-ligand interactions. These findings highlight the biomedical potential of FBRE-synthesized Ag NPs, particularly for enzyme inhibition and pharmacological applications.

A chronological study on formation mechanism of nesquehonite from nanoparticles to grown crystals and its application in nanoparticle synthesis
Abstract Nesquehonite or hydrated magnesium carbonate is an ideal precursor for the production of magnesium compounds. One of the most important industrial routes for the synthesis of Nesquehonite is the reaction of MgSO4 (or MgCl2), existing in natural or desalination brines with Na2CO3. During this reaction, the viscosity (and other bulk properties) of the slurry dramatically increases after 20–40 min induction period. Such a surge of viscosity is important for the reactor engineers, as it may damage the driving motor. The current study was undertaken to 1: Elucidate the formation mechanism of the Nesquehonite crystals and its induction period, and 2: Propose a method for the production of nano MgCO3 by stopping the formation reaction in its early stage. By simultaneous monitoring of the microstructure and bulk properties using SEM, XRD, FTIR, Raman, TGA, and Rheometry, the following formation mechanism was suggested: The nano-sized nuclei of “MgCO3·3H2O” are formed, nearly instantaneously after contacting the reagents. Those nanoparticles need an induction period to form the sheet-like intermediate. Large crystals are then formed quickly through stacking of the intermediate sheets, or their horizontal extension. Glycine capping agent, that stabilizes nanoparticles and deters their merges, slows down the formation of the aforesaid intermediate. Lowering the initial supersaturation of MgCO3, on the other hand, alters the size of the nanoparticles, but does not affect the formation kinetics of “Sheet-like intermediate → Final crystals” transformation. Simultaneous usage of capping agent and spray dryer seems to be an ideal method for the production of nano MgCO3 from the aforesaid reaction.

GNGT1 is a potential prognostic and immunologic biomarker in gastric cancer
Abstract Gastric cancer(GC) is the fifth most common type of cancer worldwide and ranks third in terms of cancer-related mortality. Immunotherapy has shown promising outcomes and greatly extended survival in individuals with advanced stomach cancer. To improve the immunotherapy response in patients with GC, it is necessary to discover new molecular targets. The associations among G protein subunit gamma transducin 1(GNGT1) expression, clinicopathological features, and prognosis were assessed via the UALCAN and Kaplan-Meier databases. The CIBERSORT algorithm in R software and single-sample gene set enrichment analysis(ssGSEA) were used to analyse the proportions of infiltrating immune cells in the high-expression group and the low-expression group.GNGT1 expression was substantially greater in GC tissues than in normal tissues, and patients with GC who had high GNGT1 expression had worse clinicopathological characteristics and survival outcomes. Immunohistochemistry(IHC) experiments on stomach adenocarcinoma(STAD) samples confirmed the aberrant expression of GNGT1 and its association with a poor prognosis. Subsequent investigations revealed substantial negative correlations between GNGT1 and tumour mutational burden(TMB), microsatellite instability(MSI), immune cell infiltration, immune cell gene marker expression and immunological checkpoint expression in patients with STAD.GNGT1 is a reliable biomarker in patients with GC that also has an immunomodulatory function in this disease and may accelerate GC development by suppressing the infiltration of T cells, dendritic cells, M1 macrophages and B cells.

Gain efficiency with streamlined and automated data processing: Examples from high-throughput monoclonal antibody production
Data management and sample tracking in complex biological workflows are essential steps to ensure necessary documentation and guarantee reusability of data and metadata. Currently, these steps pose challenges related to correct annotation and labeling, error detection, and safeguarding the quality of documentation. With growing acquisition of biological data and the expanding automatization of laboratory workflows, manual processing of sample data is no longer favorable, as it is time- and resource-consuming, prone to biases and errors, and lacks scalability and standardization. Thus, managing heterogeneous biological data calls for efficient and tailored systems, especially in laboratories run by biologists with limited computational expertise. Here, we showcase how to meet these challenges with a modular pipeline for data processing, facilitating the complex production of monoclonal antibodies from single B-cells. We present best practices for development of data processing pipelines concerned with extensive acquisition of biological data that undergoes continuous manipulation and analysis. Moreover, we assess the versatility of proposed design principles through a proof-of-concept data processing pipeline for automated induced pluripotent stem cell culture and differentiation. We show that our approach streamlines data management operations, speeds up experimental cycles and leads to enhanced reproducibility. Finally, adhering to the presented guidelines will promote compliance with FAIR principles upon publishing.
Comparison of the simplest diets to find the most effective one in developing ant colonies of Lasius niger
Abstract Nurturing, especially feeding ant colonies is a vital topic among ant researchers and ant keepers. Numerous factors contribute to growing healthy ant colonies rapidly, including, for instance, humidity levels and appropriate farming methods. Proper diet is also an essential consideration. Many articles contemplate the potential of artificial diets. Variable carbohydrate-based diets have been tested but the role of protein has largely been overlooked. We aimed to analyse the effects of these diets to be able to standardize and compare results of different laboratories. We assessed the most readily available, natural, inexpensive, known, and efficient diets to ensure optimal nutrition for ant colonies by analysing the development of 100 Lasius niger colonies. They were given four different carbohydrate-based diets in the first year and four different protein-based diets in the second year. Based on our findings, honey water was the best carbohydrate source. The best protein diet, however, consisted of crickets, which positively influenced not only the development but also the survival success of the colonies during the wintering period. Thus, we suggest rearing laboratory colonies of L. niger on honey water and crickets. It would be worth repeating this study with different ant species and doing biochemical analysis on the diets.
Okra mucilage as an encapsulating agent for magnesium hydroxide nano-capsules in oral drug delivery
Abstract The study investigates the utilization of okra mucilage as an encapsulating agent for the development of magnesium hydroxide nano-capsules for oral drug delivery systems. Given the advancements in drug delivery systems (DDSs) and the emerging interest in nanostructured drug delivery systems (NDDSs), the potential of okra mucilage for nanoencapsulation is explored. NDDSs hold promise for enhancing therapeutic efficacy while minimizing adverse effects. Okra mucilage is known for its biodegradability, non-toxicity, and cost-effectiveness, making it a suitable candidate for encapsulation processes. The sol–gel encapsulation method is employed to fabricate the encapsulated magnesium hydroxide particles (EMgPs). The EMgPs were characterized using XRD, FT-IR, Raman spectroscopy, and FESEM/EDS, confirming the successful encapsulation of magnesium hydroxide within the okra mucilage. The hydrophilic properties of the EMgPs were also assessed through contact angle measurements, revealing promising wettability for efficient drug release in the digestive system. Release tests in a simulated digestive system environment demonstrated a controlled and sustained release profile (zero-order release) of magnesium hydroxide from the EMgPs with a rate constant of 0.75 and 0.2894 mg mL−1 h−1 in gastric phase and intestinal phase, respectively. The findings highlight the potential of okra mucilage as an encapsulating agent in oral drug delivery systems and provide insights for further research in the field of nanomedicine.

CSN6 aggravates inflammation and Myocardial injury in macrophage of sepsis model by MIF
Abstract Sepsis, one of the leading causes of death in critically ill patients, is characterized by multiple organ dysfunction due to a dysregulated immune response to infection. Caregivers closely monitor patients’ organ function indicators in the intensive care unit,which is essential for the early identification and management of organ dysfunction cauxsd by sepsis. Hence, we investigated the effects of CSN6 on sepsis and its underlying mechanism. RAW264.7 cell inducted with lipopolysaccharide (LPS) and adenosine triphosphate (ATP). CSN6 protein expression increased in an in vitro model of sepsis. We collected samples from 10 sepsis patients (It was collected under strict compliance with ethical norms and nursing procedures) and performed single-cell analysis for CSN6 expression. CSN6 aggravated macrophage inflammation in an in vitro model of sepsis. CSN6 aggravated macrophage ferroptosis in an in vitro model of sepsis. CSN6 aggravates mitochondrial damage in an in vitro model of sepsis. CSN6 induces MIF expression in macrophages in an in vitro model of sepsis. MIF inhibitors reduced the effects of CSN6 on inflammation and ferroptosis in an in vitro sepsis model. CSN6 protein at 11-ARG, 21-ARG, 31-LEU, and 32-ASP linked to MIF protein at 280-ASN and 366-SER. In conclusion, CSN6 appears to aggravate inflammation in macrophages in a sepsis model via MIF signaling. This finding suggests that future therapeutic strategier targeting the CSN6 and MIF pathways may require nurses to closely monitor changes in inflammatory responses and potential treatment side effecta at the bedside. Further research involving in vivo models, such as examining CSN6 and MIF expression levels in macrophages or monocytes from sepsis and control mice, is essential to fully confirm these findings and establish the therapeutic potential of targeting the CSN6/MIF axis in sepsis. The nursing research team plays a key role in translating basic research findings into clinical practice,including the developpment of early warning tools and individualized management programs based on these biomarkers.
