Authors: Kim Se Yun , Lee Jong Min , Kwon Soon Chan
Published: November 2024

Managing giant partially thrombosed intracranial aneurysms presents significant challenges due to their unfavorable natural history and the lack of standardized treatment approaches. Conventional treatments, whether open surgical or endovascular, often struggle to manage these aneurysms effectively, resulting in high recurrence rates or significant morbidity. The patient was a 62-year-old male with a symptomatic giant partially thrombosed aneurysm at the tip of the basilar artery, presenting with left-sided hemiparesis and dysarthria. Diagnostic imaging revealed a giant aneurysm with a wide-necked, canalized portion. A two-stage endovascular treatment was conducted, involving a balloon occlusion test and intraoperative monitoring for maximum patient safety. The treatment utilized stent-assisted Woven EndoBridge (WEB) embolization and serial bilateral vertebral artery trapping. The procedure successfully isolated the aneurysm and postoperative imaging confirmed the absence of recanalization, preserving the intact posterior circulation. The patient showed stable recovery and no neurological deficits during the 12-month follow-up period. This technical note demonstrates the feasibility and efficacy of strategically integrating intrasaccular flow diversion using a WEB device and flow reversal through bilateral vertebral artery trapping for treating giant partially thrombosed aneurysms.

Authors: Ragguett Renee-Marie , Climans Seth , Boldt Gabe , Houpt Jacob , Tan Vivian
Published: November 2024

Mutations in the SDHB gene cause a characteristic syndrome that includes paragangliomas (PGL) and phaeochromocytomas (PCC). Herein we present a rare case of an ependymoma in a patient with a germline SDHB mutation.

A 41-year-old man with a positive family history of PGL/PCC syndrome was found to have the familial SDHB mutation. Screening imaging for paragangliomas revealed an incidental presumed ependymoma originating from the fourth ventricle. He was followed with serial imaging to assess for progression of the lesion. Due to slow, substantial growth of the tumour, and increasing symptoms which included diplopia, unsteadiness, and wide-based gait, he underwent a resection 5 years after the lesion’s identification. Following resection of the tumour, the pathology confirmed the tumour as a posterior fossa type B (PFB) ependymoma of the fourth ventricle. Unfortunately, on Day 26 post-operatively, the patient had a pulmonary embolism and died. His family consented to an autopsy, which revealed the presence of a clinically-silent pituitary neuroendocrine tumour (PitNET).

Though ependymomas are not commonly seen in PGL/PCC syndrome, they can occur. This case represents the first molecularly-characterised ependymal tumour described in this tumour predisposition syndrome. Clinicians ought to be aware of the risk of ependymoma in patients with PGL/PCC syndrome and consider this tumour when conducting their screening and follow-up of asymptomatic SDHx mutation carriers.

Published: November 2024

Introduction: Gene expression assays, such as the MammaPrint® (Agendia, Amsterdam, the Netherlands) 70-gene signature, are increasingly used by oncologists to understand breast cancer biology and improve treatment planning. This study assesses the utility of MammaPrint genomic risk in predicting treatment outcomes for women with breast cancer in a retrospective German cohort with a 10-year follow-up, treated based on clinicopathological features alone.

Methods: The sample set of 117 tumours from the ‘Patients Tumour Bank of Hope’ (PATH) biobank with 10-year follow-up were classified using MammaPrint into high or low risk of distant metastasis. Patients were previously treated according to St. Gallen and Adjuvant! Online high- or low-risk criteria. Statistical analyses compared overall survival (OS) and treatment outcomes between clinical and genomic risk groups.

Results: Among the 78 patients with clinically high-risk tumours, 50% (39) were reclassified as MammaPrint low risk. In total, 57.3% (67/117) patients with MammaPrint low-risk tumours demonstrated a significantly higher 10-year OS of 93.4%, irrespective of nodal status, compared to patients with MammaPrint high-risk tumours (71.2%; p=0.001). Chemotherapy improved OS in patients with MammaPrint high-risk tumours by 29.4%, but not for patients with MammaPrint low-risk tumours (p=0.016). Discussion: The findings confirm the prognostic utility of MammaPrint for identifying genomically low-risk patients who may safely omit chemotherapy while suggesting genomically high-risk cases may benefit from chemotherapy. By providing a more precise assessment of cancer risk than traditional clinicopathological methods alone, MammaPrint may help reduce unnecessary treatments and improve long-term quality of life for patients diagnosed with early-stage breast cancer.
Corrosion Behavior of SLMed Ti6Al4V-Equine Bone Nanocomposites
Authors: Kim Se Hee , Shin Se Eun
Published: November 2024

Ti6Al4V is one of the most widely used Ti alloys in biomedical applications, such as orthopedic and dental implants, due to its excellent mechanical properties, biocompatibility, and high corrosion resistance. Metal implants require high bonding strength between the implant and bone for long-term use in the human body; Hydroxyapatite (HAp) has generally been used as it can be expected to provide high osseointegration. However, in this study, Equine Bone (EB), which is a biowaste with a similar chemical composition to HAp and is environmentally friendly, was used instead. Ti6Al4V and EB were mixed through ball milling and then fabricated into Ti6Al4V-0.05EB composites using Selective Laser Melting (SLM). During the SLM process, localized high thermal gradients and rapid cooling rates leads to high strength and low ductility, making it challenging to use as a biomaterial. To overcome these issues, heat treatment was performed at temperatures corresponding to the β phase transformation. Subsequently, to evaluate the corrosion behavior after implantation in the body, the corrosion resistance of the Ti6Al4V-0.05EB nanocomposites was assessed through potentiodynamic polarization tests in a 0.9% NaCl solution, which simulates the physiological environment of the human body. Additionally, the effects of EB addition and heat treatment temperature on the corrosion behavior were also observed.

Published: November 2024

Although sulfide-polyacrylonitrile (SPAN) is considered a promising cathode material for various battery applications, their application in thermal batteries has not yet been explored. Herein we synthesized carbonized SPAN (c-SPAN) to enhance the thermal stability of SPAN and evaluated its application as a cathode for thermal batteries. The efficiency of c-SPAN materials was demonstrated by comprehensive structural analysis and thermal stability evaluation, including scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman, and thermogravimetric analysis (TGA). The c-SPAN exhibited significantly improved thermal stability compared to conventional PAN, which was attributed to the stable structure resulting from the chemical bonding of sulfur to the PAN-derived turbostratic carbon matrix. In addition, the bond dissociation energy of the C–S bond (272 kJ/mol) was higher than that of the S–S bond (251 kJ/mol), further contributing to the enhanced thermal stability. The thermal stability of c-SPAN was considerably affected by the mixing method and thermal treatments conditions, and maintained stability up to 500°C under optimal conditions. Additionally, a thermal battery incorporating c-SPAN was successfully operated, indicating that the c-SPAN material developed in this study is a viable candidate for thermal battery applications. These results suggest it is one of the promising cathode materials for various thermal battery applications.

Authors: Huang YuanJiu , Kang Tae-Hoon , Choi Ho-Joon , Shin Young-Chul , Lee Seung-Cheol , Lee Kee-Ahn
Published: November 2024

A modified alloy (Al-0.7Mn) was designed and fabricated with an increased Mn content up to 0.7wt.% and a controlled Fe content of 0.1wt.% and compared with the conventional Al3102 (Al-0.3Mn) alloy using the air-slip casting process. Both alloys were homogenized at 510°C for 10 hours and then air-cooled. The microstructure, corrosion resistance, and mechanical properties of these materials were investigated. In the modified Al-0.7Mn alloy, the Mn/Fe ratios were found to be higher in both the α-Al matrix and the intermetallic compound of Al6(Mn, Fe) compared to those of the Al3102 alloy. Additionally, the size and volume fraction of the Al6(Mn, Fe) phase were relatively larger and higher in the modified Al-0.7Mn alloy, while the grain size of the α-Al matrix was significantly smaller. The galvanic corrosion test results indicated that the corrosion potential (Ecorr) of the conventional Al3102 alloy was higher than that of the modified Al-0.7Mn alloy (Al-0.7Mn: -682.1mV, Al3102: -652.4mV). In contrast, the corrosion current (Icorr) and corrosion rate were measured to be 49.86 μA and 0.541 mm/year for the Al-0.7Mn alloy, and 53.91 μA and 0.585 mm/year for the Al3102 alloy, respectively. Thus, it was confirmed that the corrosion rate of the Al-0.7Mn alloy was slower compared to the conventional alloy, indicating better corrosion resistance. Room temperature tensile results showed that the tensile strengths of the modified and conventional alloys were 92.55 MPa and 78.39 MPa, respectively, demonstrating that the modified Al-0.7Mn alloy achieved higher strength without a significant decrease in ductility. This improvement is attributed to the higher Mn/Fe wt.% ratio in the Al6(Mn, Fe) phase of the modified Al-0.7Mn alloy, which can reduce the detrimental effect of Fe element and enhance the corrosion resistance. Additionally, the larger size and higher volume fraction of Al6(Mn, Fe) in the modified alloy, along with the smaller grain size, may contribute to the higher tensile strength. Based on these results, the corrosion mechanisms and deformation behavior of the modified Al-0.7Mn alloy were also discussed.

Smart modeling of soil-foundation interaction using coupled mechanisms: a numerical framework for liquefaction risk mitigation
Authors: Kumari Sunita , Ghani Sufyan , Kumar Amrendra
Published: November 2024

This study investigates the impact of nearby structures on the cyclic settlement mechanisms of shallow foundations in liquefiable soils using a numerical model based on Biot’s porous media theory. The model predicts excess pore water pressure and settlement by coupling equilibrium and continuity equations, solved using an implicit time integration scheme. Soil nonlinearity under cyclic loading is represented using generalized plasticity, boundary surfaces, and non-associated models. Three scenarios are simulated to study the effect of spacing between light and heavy foundations and variation in acceleration intensity. Results show that as spacing between foundations increases, lateral displacement and settlement decrease. Excess pore water pressure generation also decreases with increased foundation spacing. Soil just below the foundation exhibits maximum settlement, decreasing with depth. When input acceleration increases from 0.1 g to 0.15 g and 0.2 g, settlement increases by 40%–55% and 90%–110% respectively for both light and heavy foundations, regardless of spacing. Excess pore water pressure also increases sharply with higher acceleration intensity. The findings highlight the importance of considering foundation-soil-foundation interaction effects in liquefaction-prone urban settings and provide insights for designing resilient shallow foundations.

Floating offshore wind turbines (FOWTs) are highly susceptible to vibrations caused by wind and sea wave oscillations, necessitating effective vibration reduction strategies to ensure stability and optimal performance. This study investigates the effectiveness of a barge-type FOWT integrated with oscillating water columns (OWCs) in reducing oscillations, particularly in rotational modes. A hybrid FOWT-OWCs system was designed, and its vibration mitigation capabilities were assessed through both numerical simulations and experimental tests. The numerical approach focused on controlling airflow in the OWCs, while the experimental tests validated these results under similar conditions. A strong agreement between the simulations and experiments was observed, particularly in reducing platform pitch oscillations, even under irregular wave conditions. The open OWC-based platform outperformed the closed design, reducing pitch angle oscillations from 17.51° to 14.38° for waves with a 10-s dominant frequency. Benchmark tests confirmed this trend, with the open moonpool-based platform achieving a reduction from 18.41° to 12.23°. These findings demonstrate the potential of OWCs to improve the stability and performance of FOWTs, with experimental validation providing confidence in the numerical predictions.

Environmental hypoxia, resulting from reduced oxygen supply, poses a significant risk of dysfunctioning and damaging the neurocognitive system, particularly in relation to anxiety and stress. Inadequate oxygenation can lead to acute and chronic brain damage. Scholars used behavioral, hemodynamic, and electromagnetic neurofunctional techniques to investigate the effects of normobaric and hypobaric hypoxia on neurocognitive systems. They found a correlation between hypoxia, altered psychomotor responses, and changes in EEG alpha, theta, beta, and gamma rhythms, which affect spatial attention and memory. Hypoxia affects event related potential (ERP) components differently depending on latency. Perceptual responses N1 and P2 remain largely unaffected, while the amplitudes of preattentive MMN, vMMN, and P3a are significantly altered. Late latency components related to attention, particularly P3b, are also altered. These changes illustrate the spectrum from sensory detection to more complex cognitive processing, highlighting the brain's efficiency in managing information. Interestingly, the amplitudes of P3b, ADAN and CNV can increase with increased cognitive demands in hypoxia. This suggests a compensatory response. Prolonged exposure exacerbates these effects, resulting in compensatory delayed behavioral responses and alterations in behavioral monitoring and conflict inhibitory control, as reflected by reduced amplitudes in some attention related ERP components, including N2, N2pc, and ERN. Thus, neurocognitive function and integrity are under stress. ERP sources and hemodynamic images reveal that vulnerable brain regions include the frontal prefrontal cortices, hippocampus, basal ganglia, and parietal and visual cortices, which are essential for attention related processes like decision making and spatial memory. The auditory system appears less affected.

Introduction

Vegetation plays a crucial role in terrestrial ecosystems, acting as a vital link connecting the lithosphere, hydrosphere, and atmosphere in terms of energy flow and material cycling. Changes in surface vegetation significantly regulate the water cycle, energy flow within terrestrial surfaces, and global carbon balance.

Methods

This study focuses on nine major river basins in China to quantitatively investigate the impacts of climate factors, vegetation dynamics, and land use changes on carbon use efficiency (CUE) and water use efficiency (WUE).

Results

The primary controlling factors of WUE trends are NDVI (average contribution: 33.75% ± 6.90%) and VPD (average contribution: 28.04% ± 3.98%). NDVI predominates in the Haihe, Yellow River, Yangtze River, Pearl River, and Songliao River basins, while shortwave radiation (Srad) dominates in the southeastern rivers and inland river areas, and humidity (Shum) in the southwestern river basins. For CUE trends, the main controlling factors are Srad (average contribution: 36.46% ± 3.40%) and precipitation (Pre) (average contribution: 26.72% ± 5.20%). NDVI negatively influences the Huaihe River and southeastern river basins, while Pre negatively influences the Songliao River and Yellow River basins, and Srad negatively influences the Huaihe and southwestern river basins. Pre predominates in the Huaihe, Songliao, Haihe, southwestern river basins, and inland river areas, while Srad predominates in the Pearl River, Yangtze River, and Yellow River basins.

Discussion

Climate factors and vegetation dynamics have significant regional impacts on WUE and CUE across different river basins, especially the roles of NDVI and VPD on WUE, and Srad and precipitation on CUE. These differences underscore the importance of developing region-specific management strategies to optimize ecosystem services in each basin.

Introduction

The cartilage endplate (CEP) plays a crucial role as both a mechanical barrier and nutrient channel for the intervertebral disc, but it is vulnerable to excessive axial loading. We modified the Ilizarov external fixator and applied it to the CEP of the rat tail to impose diurnal, controllable excess axial loading. The objective was to measure morphological changes in the CEP when subjected to loading during the aging process.

Methods

Two Kirschner wires were, respectively, inserted into the center of the eighth and ninth coccygeal vertebrae (Co8/9) of rat (n = 54) to apply axial loading to the CEP. A remote control device was used to establish the diurnal loading schedule. At the end of 4, 8, and 12-week periods, the Co8/9 CEPs in each group were analyzed using MRI, histological staining, and immunohistochemical staining techniques.

Results

The novel Ilizarov model that we modified successfully induced degeneration of the rat coccygeal CEP. MRI analysis revealed significant degenerative changes in the loaded Co8/9 CEP, including decreased signal intensity and the formation of Schmorl’s nodes at 8 and 12 weeks. Histological examination showed progressive CEP degeneration (CEPD), characterized by decreased microporosity, thinning, and structural irregularities. Immunohistochemical analysis demonstrated a significant reduction in Aggrecan and Collagen II expression in the CEP and nucleus pulposus over time. Control and sham groups maintained normal CEP structure and composition throughout the study period.

Conclusion

Excessive axial loading induced CEPD in the rat tail, primarily characterized by the formation of Schmorl’s nodes and a reduction in CEP microporosity in this study. Our modified Ilizarov rat tail compression model, featuring stable and controllable axial loading capabilities, provided an alternative experimental paradigm for further investigation into CEPD.
