RESUMEN
Natural killer (NK) cell is a valuable tool for immunotherapy in cancer treatment, both the cultured cell line NK92 and primary NK cells are widely studied and used in research and clinical trials. Clinical observations witnessed the improvement of patients' NK cells in terms of cell counts and cytotoxic activity upon dasatinib treatment, an approved drug for chronic myeloid leukaemia and Ph+ acute lymphocytic leukaemia. Several studies supported the clinical observations, yet others argued a detrimental effect of dasatinib on NK cells. Due to the complex conditions in different studies, the definite influence of dasatinib on NK92 and primary NK cells remains to be settled. Here, we used a well-defined in vitro system to evaluate the effects of dasatinib on NK92 cells and peripheral blood (PB)-NK cells. By co-culturing NK cells with dasatinib to test the cell counts and target cell-killing activities, we surprisingly found that the chemical influenced oppositely on these two types of NK cells. While dasatinib suppressed NK92 cell proliferation and cytotoxic activity, it improved PB-NK-killing tumour cells. RNA sequencing analysis further supported this finding, uncovering several proliferating and cytotoxic pathways responding invertedly between them. Our results highlighted an intrinsic difference between NK92 and PB-NK cells and may build clues to understand how dasatinib interacts with NK cells in vivo.

Lithium-sulfur (Li-S) batteries with high theoretical energy density (2600 Wh kg-1) are considered to be one of the most promising secondary batteries. However, the practical application of Li-S batteries is limited by the polysulfides shuttling and unstable lithium metal anodes. Herein, an asymmetric separator (CACNM@PP), composed of Co-Ni/MXene (CNM) on the cathode and Cu-Ag/MXene (CAM) on the anode for high-performance Li-S batteries is reported. For the cathode, CNM provides a synergistic effect by integrating Co, Ni, and MXene, resulting in strong chemical interactions and fast conversion kinetics for polysulfides. For the anode, CAM with abundant lithiophilicity active sites can lower the nucleation barrier of Li. Moreover, LiCl/LiF layers are generated in situ as an ion conductor layer during charging and discharging, inducing a uniform deposition of Li. Therefore, the assembled cells with the CACNM@PP separators harvest excellent electrochemical performance. This work provides novel insights into the development of commercially available high-energy density Li-S batteries with asymmetric separators.
RESUMEN
Driven by the strong adsorptive and catalytic ability of metal sulfides for soluble polysulfides, it is considered as a potential mediator to resolve the problems of shuttle effect and slow reaction kinetics of polysulfides in lithium-sulfur (Li-S) batteries. However, their further development is limited by poor electrical conductivity and bad long-term durability. Herein, one type of new catalyst composed of SnS/SnS2 heterostructures on hierarchical porous carbon (denoted as SnS/SnS2-HPC) by a simple hydrothermal method is reported and used as an interlayer coating on the conventional separator for blocking polysulfides. The SnS/SnS2-HPC integrates the advantages of a porous conductive network for promoting the transport of electrons and an enhanced electrocatalyst for accelerating polysulfides conversion. As a result, such a cell coupled with a SnS/SnS2-HPC interlayer exhibits a long-term lifespan of 1200 cycles. This work provides a new cell configuration by using heterostructures with a built-in electric field formed from a p-n heterojunction to improve the performance of Li-S batteries.
RESUMEN
The development of bifunctional electrocatalysts with excellent performance in both the hydrogen evolution reaction (HER) and sulfide oxidation reaction (SOR) remains a formidable challenge. Herein, we experimentally synthesize a NiO/RuO2 p-n heterojunction nanofoam that exhibits highly desirable electrocatalytic properties for both the HER and the SOR. We further design an electrolytic cell by pairing alkaline HER with SOR utilizing the NiO/RuO2 heterojunction nanofoam as both the anode and the cathode, which demands a low applied voltage of 0.846 V to achieve a current density of 10 mA cm-2. Density functional theory calculations confirm that the formation of the NiO/RuO2 p-n heterojunction nanofoam effectively regulates the electronic structure, thereby boosting the electrocatalytic performances for both HER and SOR. This work not only provides a novel strategy to prepare an efficient and stable nanofoam electrocatalyst for hydrogen production but also highlights the potential application of oxide heterojunction electrocatalysts in treating sulfur-containing waste liquid.
RESUMEN
Hemiptera insects exhibit a close relationship to plants and demonstrate a diverse range of dietary preferences, encompassing phytophagy as the predominant feeding habit while a minority engages in carnivorous or haematophagous behaviour. To counteract the challenges posed by phytophagous insects, plants have developed an array of toxic compounds, causing significant evolutionary selection pressure on these insects. In this study, we employed a comparative genomics approach to analyse the expansion and contraction of gene families specific to phytophagous insect lineages, along with their adaptive evolutionary traits, utilising representative species from the Hemiptera order. Our investigation revealed substantial expansions of gene families within the phytophagous lineages, especially in the Pentatomomorpha branch represented by Oncopeltus fasciatus and Riptortus pedestris. Notably, these expansions of gene families encoding enzymes are potentially involved in hemipteran-plant interactions. Moreover, the adaptive evolutionary analysis of these lineages revealed a higher prevalence of adaptively evolved genes in the Pentatomomorpha branch. The observed branch-specific gene expansions and adaptive evolution likely contribute significantly to the diversification of species within Hemiptera. These results help enhance our understanding of the genomic characteristics of the evolution of different feeding habits in hemipteran insects.

Chemical signals play a central role in mediating insect feeding and reproductive behavior, and serve as the primary drivers of the insect-plant interactions. The detection of chemical signals, particularly host plant volatiles, relies heavily on the insect's complex olfactory system. The Bemisia tabaci cryptic species complex is a group of globally important whitefly pests of agricultural and ornamental crops that have a wide range of host plants, but the molecular mechanism of their host plant recognition is not yet clear. In this study, the odorant coreceptor gene of the Whitefly MEAM1 cryptic species (BtOrco) was cloned. The coding sequence of BtOrco was 1413 bp in length, with seven transmembrane structural domains, and it was expressed primarily in the heads of both male and female adult whiteflies, rather than in other tissues. Knockdown of BtOrco using transgenic plant-mediated RNAi technology significantly inhibited the foraging behavior of whiteflies. This inhibition was manifested as a reduced percentage of whiteflies responding to the host plant and a prolonged foraging period. Moreover, there was a substantial suppression of egg-laying activity among adult female whiteflies. These results indicate that BtOrco has the potential to be used as a target for the design of novel active compounds for the development of environmentally friendly whitefly control strategies.

Abiotic CH4 production driven by Fenton-type reactive oxygen species (ROS) has been confirmed to be an indispensable component of the atmospheric CH4 budget. While the chemical reactions independent of Fenton chemistry to ROS are ubiquitous in nature, it remains unknown whether the produced ROS can drive abiotic CH4 production. Here, we first demonstrated the abiotic CH4 production at the soil-water interface under illumination. Leveraging this finding, polymeric carbon nitrides (CNx) as a typical analogue of natural geobattery material and dimethyl sulfoxide (DMSO) as a natural methyl donor were used to unravel the underlying mechanisms. We revealed that the ROS, photocatalytically produced by CNx, can oxidize DMSO into CH4 with a high selectivity of 91.5 %. Such an abiotic CH4 production process was further expanded to various non-Fenton-type reaction systems, such as electrocatalysis, pyrocatalysis and sonocatalysis. This work provides insights into the geochemical cycle of abiotic CH4, and offers a new route to CH4 production via integrated energy development.

RESUMEN
Objective: The study aimed to explore the genotype and allele distributions of dopamine D2-like receptor (DRD2) gene -141C and C957T polymorphisms in the Chinese Han population with dyslipidemia, as well as their association with serum lipid levels. Methods: One hundred fifty patients with dyslipidemia and 150 healthy people were recruited as the case and the control groups, respectively. Serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol levels were detected. The target sequence of DRD2 polymorphisms was amplified by polymerase chain reaction and genotyped via Sanger sequencing. Results: In DRD2 gene C957T (rs6277), three genotypes of CC, CT, and TT were detected with the frequencies of 92.67%, 6.67%, 0.67% in dyslipidemia cases, and 83.33%, 14.67%, 2.00% in the controls, respectively. The CT genotype and T allele frequencies were significantly low in the case group relative to the control group. After adjusting to other clinical indicators, the CT genotype of C957T polymorphism (hazard ratio = 0.401, 95% confidence interval = 0.181-0.890, p < 0.05) was still related to a significantly reduced risk of dyslipidemia. The C957T CT genotype carriers had the lowest values of serum TC, TG, LDL, and the highest values of serum HDL-C. Conclusion: DRD2 gene C957T polymorphism was an independent influencing factor associated with the susceptibility to dyslipidemia, and the CT genotype was associated with decreased odds of susceptibility to dyslipidemia.
RESUMEN
This study unveils a machine learning (ML)-assisted framework designed to optimize the stacking sequence and orientation of carbon fiber-reinforced polymer (CFRP)/metal composite laminates, aiming to enhance their mechanical properties under quasi-static loading conditions. This work pioneers the expansion of initial datasets for ML analysis in the field by uniquely integrating the experimental results with finite element simulations. Nine ML models, including XGBoost and gradient boosting, were assessed for their precision in predicting tensile and bending strengths. The findings reveal that the XGBoost and gradient boosting models excel in tensile strength prediction due to their low error rates and high interpretability. In contrast, the decision trees, K-nearest neighbors (KNN), and random forest models show the highest accuracy in bending strength predictions. Tree-based models demonstrated exceptional performance across various metrics, notably for CFRP/DP590 laminates. Additionally, this study investigates the impact of layup sequences on mechanical properties, employing an innovative combination of ML, numerical, and experimental approaches. The novelty of this study lies in the first-time application of these ML models to the performance optimization of CFRP/metal composites and in providing a novel perspective through the comprehensive integration of experimental, numerical, and ML methods for composite material design and performance prediction.
RESUMEN
In vitro cell culturing witnessed its applications in scientific research and industrial activities. Attempts to shorten the doubling time of cultured cells have never ceased. In plants, auxin is applied to promote plant growth, the synthetic derivative 1-Naphthaleneacetic acid (NAA) is a good example. Despite the auxin's naturally occurring receptors are not present in mammalian cells, studies suggested they may affect cell culturing. Yet the effects and mechanisms are still unclear. Here, an up to 2-fold increase in the yield of in vitro cultured human cells is observed. Different types of human cell lines and primary cells are tested and found that NAA is effective in all the cells tested. The PI staining followed by FACS suggested that NAA do not affect the cell cycling. Apoptosis-specific dye staining analysis implicated that NAA rescued cell death. Further bulk RNA sequencing is done and it is identified that the lipid metabolism-engaging and anti-apoptosis gene, ANGPTL4, is enhanced in expression upon NAA treatment. Studies on ANGPTL4 knockout cells indicated that ANGPTL4 is required for NAA-mediated response. Thus, the data identified a beneficial role of NAA in human cell culturing and highlighted its potency in in vitro cell culturing.

Purpose: This two-center study aimed to explore the main prognostic factors affecting the final disease status in children and adolescents with differentiated thyroid cancer (caDTC) following total thyroidectomy and radioiodine therapy (RAIT). Materials and methods: All caDTC patients from two centers in the period from 2004-2022 were retrospectively included. At the last follow-up, the patients' disease status was assessed and classified as an incomplete response (IR) or as an excellent or indeterminate response (EIDR). Then, the difference in preablation stimulated thyroglobulin (ps-Tg) levels between the two groups was compared, and the threshold for predicting IR was determined using receiver operating characteristic (ROC) analysis. Moreover, univariate and multivariate analyses were conducted to identify the factors influencing the patients' ultimate disease outcomes. Results: A total of 143 patients (98 females, 45 males; median age 16 years) were recruited. After a median follow-up of 42.9 months, 80 patients (55.9%) exhibited an EIDR, whereas 63 patients (44.1%) exhibited an IR. Patients with an IR had significantly greater ps-Tg levels than did those with an EIDR (median ps-Tg 79.2 ng/mL vs. 9.3 ng/mL, p<0.001). The ROC curve showed that ps-Tg ≥20 ng/mL was the most accurate for predicting IR at the last follow-up. According to multivariate analysis, only ps-Tg, T stage and the therapeutic response to initial RAIT were significantly associated with IR. Conclusion: In caDTC patients, the ps-Tg level, T stage, and response to initial RAIT are critical final outcome indicators.

Objetivo: Determinar las modificaciones biométricas en pacientes miopes con implante de la lente fáquica ACRIOL 128. Métodos: Se realizó un estudio transversal con 31 ojos (17 pacientes) con alta miopía tratados con implante de lente fáquica ACRIOL 128, entre septiembre 2016 y febrero 2019, los cuales tenían mediciones biométricas preoperatorias con el sistema IOL Master 3.0.2 y estabilidad refractiva posoperatoria (≤ 0,5 dioptrías) después de los tres meses del implante. Se les efectuaron las mediciones posoperatorias con el propio IOL Master 3.0.2 en modo lente fáquica y con el sistema Scheimpflug Pentacam AXL para compararlas, mediante la prueba t para datos pareados, con una significación del 95 por ciento. Resultados: La edad promedio fue de 29,82 ± 5,99 años, el 82,4 por ciento del sexo femenino. El equivalente esférico preoperatorio medio fue de -12,00 ± 4,10 dioptrías. La diferencia de longitud axial y profundidad de la cámara anterior en milímetros entre el pre- y posoperatorio fue significativa con IOL Master 3.0.2 (0,13 ± 0,33 y -0,08 ± 0,17) y Pentacam AXL (0,12 ± 0,32 y -0,10 ± 0,24), respectivamente. Sin embargo, las posoperatorias entre ambos equipos no fueron significativas (p>0,05) para estas variables, pero sí para las queratometrías. Conclusiones: El implante de la lente fáquica ACRIOL 128 modifica la medición de la longitud axial y la profundidad de la cámara anterior. El IOL Master 3.0.2 y el Pentacam AXL ofrecen mediciones de longitud axial y profundidad de cámara anterior posoperatorias similares, no así para las queratometrías(AU)
Objective: To determine the biometric modifications in myopic patients with ACRIOL 128 phakic lens implantation. Methods: A cross-sectional study was performed on 31 eyes (17 patients) with high myopia treated with ACRIOL 128 phakic lens implant, between September 2016 and February 2019, which had preoperative biometric measurements with the IOL Master 3.0.2 system and postoperative refractive stability (≤ 0.5 diopters) after three months of implantation. Postoperative measurements were performed with the IOL Master 3.0.2 in phakic lens mode and with the Scheimpflug Pentacam AXL system for comparison, using the t-test for paired data, with 95% significance. Results: The average age was 29.82 ± 5.99 years, 82.4por ciento female. The mean preoperative spherical equivalent was -12.00 ± 4.10 diopters. The difference in axial length and anterior chamber depth in millimeters between pre- and postoperative was significant with IOL Master 3.0.2 (0.13 ± 0,33 and -0.08 ± 0.17) and Pentacam AXL (0.12 ± 0.32 and -0.10 ± 0.24), respectively. However, postoperative between the two teams were not significant (p > 0.05) for these variables but significant for keratometries. Conclusions: Implantation of the ACRIOL 128 phakic lens modifies the measurement of axial length and anterior chamber depth. The IOL Master 3.0.2 and Pentacam AXL provide similar postoperative axial length and anterior chamber depth measurements, but not for keratometries(AU)

Introducción: El implante de una lente intraocular fáquico para corregir defectos de la refracción presenta una serie de ventajas respecto a otras técnicas como la cirugía refractiva corneal o la extracción de cristalino transparente. Objetivo: Describir los cambios en la calidad de vida relacionados con la función visual en la corrección de alta miopía con implante de lente fáquico ACR-128. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo con análisis estadístico separado por ojos. La muestra total se correspondió con 91 ojos (46 derechos y 45 izquierdos) de 49 pacientes a los que se les implantó lente fáquico ACR-128 para la corrección de miopía. Mediante el test de Pelli-Robson se determinó la sensibilidad al contraste binocular a varias frecuencias espaciales y se les aplicó el cuestionario NEI-VFQ-25 antes de la cirugía (pretest) y a los tres meses de realizada la misma (postest). El análisis estadístico se realizó con la prueba T para datos pareados, con una significación del 95 por ciento. Resultados: Edad media 28,73 ± 5,85 años. Predominio del sexo femenino (71,43 por ciento). Hubo diferencias significativas en todas las frecuencias espaciales de la sensibilidad al contraste binocular entre el pre- y posoperatorio (p < 0,01). Al comparar el pretest y el postest (valoración retrospectiva de la calidad de vida prequirúrgica) no se encontraron diferencias significativas, lo que indicó que no hubo recalibración y que las diferencias con el postest que fueron significativas corroboren el verdadero cambio en la calidad de vida de estos pacientes tras la cirugía.

Introduction: Phakic intraocular lens implantation to correct refraction defects has a number of advantages with respect to techniques such as corneal refractive surgery or clear lens extraction. Objective: Describe the changes in vision-related quality of life resulting from high myopia correction by ACR-128 phakic lens implantation. Methods: A prospective longitudinal descriptive study was conducted with independent statistical analysis for each eye. The total sample was 91 eyes (46 right and 45 left) of 49 patients undergoing ACR-128 phakic lens implantation for myopia correction. The Pelli-Robson test was used to determine binocular contrast sensitivity at various spatial frequencies, and the NEI VFQ-25 questionnaire was applied before surgery (pre-test) and three months after surgery (post-test). Statistical analysis was based on the paired T-test with a significance level of 95 percent. Results: Mean age was 28.73 ± 5.85 years. Female sex prevailed (71.43 percent). Significant differences were found in all the spatial frequencies of binocular contrast sensitivity between the pre- and postoperative periods (p < 0.01). Comparison of pre- and post-test results (retrospective assessment of presurgical quality of life) did not find any significant differences, indicating that there was no recalibration. Significant differences with respect to the post-test confirm the actual change in these patients' quality of life after surgery. Conclusions: ACR-128 phakic lens implantation for high myopia correction improves vision-related quality of life without changes in its perception before and after surgery(AU)

RESUMEN Los errores refractivos altos son difíciles de corregir óptica y quirúrgicamente. Los pacientes que los padecen se encuentran incómodos con las gafas, ya que la calidad de su visión es deficitaria. Las lentes de contacto proporcionan mejor agudeza visual; sin embargo, en ocasiones requieren diseños especiales para ser adaptadas y pueden asociarse a complicaciones severas. La cirugía refractiva como subespecialidad busca mejorar la agudeza visual no corregida y disminuir la dependencia a gafas o lentes de contacto. Las opciones van desde los procedimientos queratorrefractivos hasta el implante de una lente intraocular, ya sea con la extracción del cristalino transparente o en un ojo fáquico. Este último ofrece ventajas al mantener la acomodación, obtener una mejor calidad óptica y cierta reversibilidad. En el mundo se han realizado múltiples trabajos en pacientes con lentes fáquicos de diferentes modelos y estos han demostrado que son seguros y confiables, aunque no son muchos los estudios sobre la calidad de vida a largo plazo; de ahí la motivación para realizar una búsqueda actualizada de diversos artículos publicados, con el objetivo de describir los resultados visuales y la calidad de vida en pacientes con implante de lentes fáquicos.

ABSTRACT High refractive errors are difficult to correct both optically and surgically. Patients suffering from them feel uncomfortable with their eyeglasses, since their visual quality is poor. Contact lenses provide better visual acuity, but they sometimes require special designs to be adjusted and may be associated to severe complications. The subspecialty of refractive surgery seeks to improve uncorrected visual acuity and reduce dependence on eyeglasses or contact lenses. Options range from keratorefractive procedures to intraocular lens implantation, be it with removal of the transparent crystalline lens or in phakic eyes. The latter provides the advantages of maintaining accommodation, obtaining better visual quality and affording a certain degree of reversibility. A great many studies have been conducted worldwide of patients with phakic lenses of various models, and these have proved to be safe and reliable. However, not many studies are available about long-term quality of life. Hence the motivation to perform an updated search for published papers about the subject, with the purpose of describing the visual results and quality of life of patients with phakic lens implants. Use was made of the Infomed platform, particularly the Virtual Health Library with all its search engines(AU)
