AbstractTo solve the problem of controlling the stability of small coal pillars under the mining disturbance of the adjacent working face, the fourth panel 403 and 404 working faces of the Gaojiabao coal mine with two mining roadways is taken as the object of this research. The comprehensive research method of combining mechanical theory analysis, coal dynamic disturbance experiments and field engineering practice was adopted. First, the analysis determined the magnitude and frequency of fracture‐related disturbance loading on the overburden roof of the working face; next, the strain and stress threshold indicators of the coal body, sensitive to the external disturbance load of 103 J magnitude (continuous disturbance deformation), were tested and obtained through a self‐developed rock creep disturbance experimental system, and the stress threshold indicators of coal body specimens sensitive to creep disturbance were defined as the long‐term strength. Then, a coal pillar‐roof mechanics structure model was established in the premining and postmining areas of the working face, and the overlying support pressure on the coal pillar body was analysed. Finally, a small coal pillar composite reinforcement support technology with ‘two‐way buttressing anchor cable for pressure reinforcement + steel pipe concrete pier column + overhead roof break’ was designed to ensuring that the coal pillar body would not be destabilised by cumulative disturbance and large deformation under disturbance. According postmining area support capacity calculations, the support loading acting on the coal pillar is approximately 17593 kN, with the stress being 2.93 MPa; and the factor of safety is approximately 1.23. After engineering practice application of this approach, the vertical deformation of the small coal pillar body and side heave disturbance deformation were effectively controlled during the working face mining disturbance, the vertical deformation of the reinforced coal pillar was only 187 mm, and the side heave deformation was finally stabilised at approximately 124 mm, which maintained good stability.

ABSTRACTScientists and researchers are investigating new energy conversion and storage devices continuously because of the current global hike in energy crisis. In this study, we utilized graphene oxide (GO) and composites of transition metallic oxides (CeO2@WO3) to fabricate electrodes intended for use in supercapacitor electrodes. These electrodes' morphology demonstrates a uniform distribution of sphere and platelet nanoparticles. The XRD measurements for these manufactured electrodes showed a noticeable crystalline character. These electrodes have outstanding electrochemical performance due to their relatively low bandgap energies. The electrochemical tests demonstrated the exceptional charge storage capabilities of the different electrodes, suggesting that CeO2/GO, WO3/GO, and CeO2@WO3/GO electrodes could be useful electrodes for supercapacitor applications. Numerous electrochemical findings made it abundantly evident that the creation of bimetallic CeO2@WO3/GO composites enhanced the supercapacitive performance and cycle stability of the electrodes.

AbstractLectins are carbohydrate‐binding proteins, whose biological effects are exerted via binding to glycoconjugates expressed on the surface of cells. Exposure to lectins can lead not only to a change in the structure and properties of cells but also to their death. Here, we studied the biological activity of lectins from the mussels Crenomytilus graynus (CGL) and Mytilus trossulus (MTL) and showed that these proteins can affect the proliferation of human lymphoma cells. Both lectins suppressed the formation of colonies as well as cell cycle progression. The mechanism of action of these lectins was not mediated by reactive oxygen species but included damaging of mitochondria, inhibition of key cell cycle points, and activation of MAPK signaling pathway in tumor cells. Computer modeling suggested that various effects of CGL and MTL on lymphoma cells may be due to the difference in the energy of binding of these lectins to carbohydrate ligands on the cell surface. Thus, molecular recognition of residues of terminal carbohydrates on the surface of tumor cells is a key factor in the manifestation of the biological action of lectins.

Authors: Narayana P. S. , Narayana L. L. 
Published: August 2024

SummaryThe genus Gisekia L. has a disputed taxonomic position. It was assigned to different ranks such as genus, tribe and family by various systematists and placed in different families, namely, Aizoaceae, Molluginaceae and Phytolaccaceae. Recent systematists favoured its inclusion in Phytolaccaceae. In the light of the findings from the present investigation together with the available data from collateral disciplines, it is tentatively suggested that Gisekia be treated under Aizoaceae and that it may be considered as a probable connecting link between the betalain families, Aizoaceae and Phytolaccaceae and anthocyanin containing Moîluginaceae.

Published: August 2024

AbstractThe increasing volume of textile waste in landfills and incineration poses severe environmental challenges. Waste valorisation of textile waste via anaerobic digestion (AD) is preferable, as it offers economic and environmental benefits, but it is hindered by textile complexity, necessitating effective pretreatment technologies to improve biogas production. This study aims to evaluate various pretreatment technologies for biogas production from textile fibres via AD. A weighted‐scoring analysis (WSA) assessed pretreatment methods based on technical, economic, environmental and operational criteria. Hydrothermal pretreatment emerged as the most technically effective method, scoring 140 owing to its substantial methane enhancement. Economically, shredding was the most viable option, scoring 125, as a consequence of low capital and O&M cost. Environmentally, hydrothermal and deep eutectic solvent (DES) pretreatments were top performers with 100 points owing to low environmental impact and positive heat reactions. In a case study conducted in the Auckland region, the potential environmental impact (PEI) obtained from hydrothermal and DES were 169 and 92 per year, respectively, resulting in minimal environmental impact. Operationally, ultrasonic and biological pretreatments scored highest owing to their ease of operation, and minimal health and safety requirements. Overall, hydrothermal pretreatment achieved the highest WSA score of 340, reflecting its balanced performance across all criteria. Hydrothermal pretreatment is the most promising technology for enhancing biogas production from textile waste. Its technical efficiency, economic feasibility and environmental benefits regarding the WSA score make it suitable for upscaling and providing a viable solution for managing textile waste in the AD plant. © 2024 The Author(s).

Published: August 2024

The cartilaginous endplate (CEP) plays a pivotal role in facilitating the supply of nutrients and, transport of metabolic waste, as well as providing mechanical support for the intervertebral disc (IVD). Recent technological advances have led to a surge in MR imaging studies focused on the CEP. This article describes the anatomy and functions of the CEP as well as MRI techniques for both qualitative and quantitative assessment of the CEP. Effective CEP MR imaging sequences require two key features: high spatial resolution and relatively short echo time. High spatial resolution spoiled gradient echo (SPGR) and ultrashort echo time (UTE) sequences, fulfilling these requirements, are the basis for most of the sequences employed in CEP imaging. This article reviews existing sequences for qualitative CEP imaging, such as the fat‐suppressed SPGR and UTE, dual‐echo subtraction UTE, inversion recovery prepared and fat‐suppressed UTE, and dual inversion recovery prepared UTE sequences. These sequences are employed together with other techniques for quantitative CEP imaging, including measurements of T2*, T2, T1, T1ρ, magnetization transfer, perfusion, and diffusion tensor parameters.Evidence Level1Technical EfficacyStage 2

AbstractMarine microbes are strongly interrelated to trace metals in the ocean. How the availability of trace metals selects for prokaryotic taxa and the potential feedback of microbial processes on the trace metal distribution in the ocean remain poorly understood. We investigate here the potential reciprocal links between diverse prokaryotic taxa and iron (Fe), manganese (Mn), copper (Cu), and nickel (Ni) as well as apparent oxygen utilization (AOU) across 12 well‐defined water masses in the Southern Indian Ocean (SWINGS—South West Indian Ocean GEOTRACES GS02 Section cruise). Applying partial least square regression (PLSR) analysis, we show that the water masses are associated with particular latent vectors that are a combination of the spatial distribution of prokaryotic taxa, trace elements, and AOU. This approach provides novel insights on the potential interactions between prokaryotic taxa and trace metals in relation to organic matter remineralization in distinct water masses of the ocean.
Toward structure and metabolism of glycogen C1‐C6 in humans at 7 T by localized 13C MRS using low‐power bilevel broadband 1H decoupling
Authors: Serés Roig Eulalia 
Published: August 2024

AbstractThis work aims to develop and implement a pulse‐acquire sequence for three‐dimensional (3D) single‐voxel localized 13C MRS in humans at 7 T, in conjunction with bilevel broadband 1H decoupling, and to test its feasibility in vitro and in vivo in human calf muscle with emphasis on the detection of glycogen C1‐C6. A localization scheme suitable for measuring fast‐relaxing 13C signals in humans at 7 T was developed and implemented using the outer volume suppression (OVS) and one‐dimensional image selected in vivo spectroscopy (ISIS‐1D) schemes, similar to that which was previously reported in humans at 4 T. The 3D 13C localization scheme was followed by uniform 13C adiabatic excitation, all complemented with an option for bilevel broadband 1H decoupling to improve both 13C sensitivity and spectral resolution at 7 T. The performance of the pulse‐acquire sequence was investigated in vitro on phantoms and in vivo in the human calf muscle of three healthy volunteers, while measuring glycogen C1‐C6. In addition, T1 and T2 of glycogen C1‐C6 were measured in vitro at 7 T, as well as T1 of glycogen C1 in vivo. The glycerol C2 and C1,3 lipid resonances were efficiently suppressed in vitro at 7 T using the OVS and ISIS‐1D schemes, allowing distinct detection of glycogen C2‐C6. While some glycerol remained in calf muscle in vivo, the intense lipid at 130 ppm was efficiently suppressed. The 13C sensitivity and spectral resolution of glycogen C1‐C6 in vitro and glycogen C1 in vivo were improved at 7 T using bilevel broadband 1H decoupling. The T1 and T2 of glycogen C1‐C6 in vitro at 7 T were consistent compared with those at 8.5 T, while the T1 of glycogen C1 in vivo at 7 T resulted similar to that in vitro. Localized 13C MRS is feasible in human calf muscle in vivo at 7 T, and this will allow further extension of this method for 13C MRS measurements such as in the brain.

Published: August 2024

AbstractAssembly of nanoparticles into superlattices yields nanomaterials with novel properties. We have recently shown that engineered protein cages are excellent building blocks for the assembly of inorganic nanoparticles into highly structured hybrid materials, with unprecedented precision. In this study, we show that the protein matrix, composed of surface‐charged protein cages, can be readily tuned to achieve a number of different crystalline assemblies. Simply by altering the assembly conditions, different types of crystalline structures were produced, without the need to further modify the cages. Future work can utilize these new protein scaffolds to create nanoparticle superlattices with various assembly geometries and thus tune the functionality of these hybrid materials.

AbstractIn pulmonary hypertension (PH) associated with chronic lung disease (CLD), identifying patients who would benefit from pulmonary vasodilators is a significant clinical challenge because the presence of PH is associated with poorer survival. This study evaluated the severity of pulmonary circulation impairment in patients with CLD‐PH using pulmonary perfusion single‐photon emission computed tomography/computed tomography (SPECT/CT). This single‐center, observational study enrolled patients with CLD‐PH who had a mean pulmonary arterial pressure (PAP) ≥ 25 mmHg, as confirmed by right heart catheterization. The primary outcome was to measure the percentage of pulmonary perfusion defect (%PPD), calculated by dividing the perfusion defect volume from perfusion SPECT images by the lung volume from CT scan images. The secondary outcome was to assess the correlation between %PPD and baseline characteristics. The median %PPD was 52.4% (interquartile range, 42.5%–72.3%) in 22 patients. In multivariate linear regression analysis, both forced vital capacity (β = 0.58, p = 0.008) and mean PAP (β = 0.68, p = 0.001) were significantly correlated with %PPD. In conclusion, significant correlation between mean PAP and %PPD in patients with CLD‐PH was observed. This noninvasive assessment of %PPD may be useful for evaluating the severity of pulmonary circulation impairment in CLD‐PH.

Published: August 2024

AbstractA systematic analysis of the advantages and challenges associated with the satellite‐based implementation of the high dimensional extended B92 (HD‐Ext‐B92) and high‐dimensional BB84 (HD‐BB84) protocol is analyzed. The method used earlier for obtaining the key rate for the HD‐Ext‐B92 is modified here and subsequently the variations of the key rate, probability distribution of key rate (PDR), and quantum bit error rate (QBER) with respect to dimension and noise parameter of a depolarizing channel is studied using the modified key rate equation. Further, the variations of average key rate (per pulse) with zenith angle and link length in different weather conditions in day and night considering extremely low noise for dimension are investigated using elliptic beam approximation. The effectiveness of the HD‐(extended) protocols used here in creating satellite‐based quantum key distribution links (both up‐link and down‐link) are established by appropriately modeling the atmosphere and analyzing the variation of average key rates with the probability distribution of the transmittance (PDT). The analysis performed here has revealed that in higher dimensions, HD‐BB84 outperforms HD‐Ext‐B92 in terms of both key rate and noise tolerance. However, HD‐BB84 experiences a more pronounced saturation of QBER in high dimensions.

Published: August 2024

AbstractThis study uses biodegradable poly(butylene adipate‐co‐terephthalate) (PBAT) and renewable natural polymer corn starch (CS) as raw materials to prepare a high starch content PBAT/CS composite material. The composite is prepared by blending corn starch in a higher proportion with biodegradable PBAT, using polyurethane prepolymer as a compatibilizer. The effects of CS content on the properties of the composites are investigated. The results of SEM show that the interface compatibility between PBAT and CS improves considerably with the addition of PCL‐based polyurethane pre‐polymer (PCLPU). Compared with PBAT/CS composites without PCLPU, the elongation at break of PBAT/CS composites with 10 wt% PCLPU is 31.9% (at the condition of 50% CS content), which is nearly 21 times higher, and the tensile strength is 18.9 MPa, which is almost two times higher. Moreover, the obtained compatible PBAT/CS composites show good thermal and hydrophilic properties. The results demonstrate that the addition of PCLPU compatibilizer has a positive impact on the fabrication of PBAT‐based polymer composites that contain high proportion of biomass. Moreover, PBAT‐based polymer composites with a high starch content hold promising prospects in the realm of biodegradable materials.

Published: August 2024

ABSTRACTOxyresveratrol (OxyR) exerts biological and pharmacological effects in a variety of tumor cells, including antioxidant action, antitumor activity, and proapoptotic effects. However, the regulation of targeted signaling pathways by OxyR and the mechanism underlying these effects in human renal cell carcinoma (RCC) have been less studied. We observed that OxyR at noncytotoxic doses did not affect the growth of human RCC cells or normal kidney HK2 cells. OxyR inhibited ACHN and Caki‐1 cell migration and invasion through targeting matrix metalloproteinase 1 (MMP1) expression. Analysis of clinical databases showed that high MMP1 expression is associated with lower overall survival (OS) in these cancers (p < 0.01). OxyR significantly inhibited the mRNA and protein expression of Sp1. Furthermore, luciferase assay results showed that OxyR inhibited Sp1 transcriptional activity. Additionally, OxyR preferentially suppressed the activation of ERK and PKCα. Treatment with U0126 (MEK inhibitor) or G06976 (PKCα inhibitor) clearly decreased Sp1 and MMP1 expression and inhibited RCC cell migration and invasion. In conclusion, OxyR may be a potential antitumor therapy for the inhibition of migration and invasion by controlling p‐ERK/Sp1 and p‐PKCα/Sp1‐mediated MMP1 expression in RCC.
