Published: September 2024

Specimen data play a crucial role in geographical distribution research. In this study, the collection information of liverwort specimens in China was compiled and analyzed to investigate the history, current status, and limitations of liverwort research in China. By utilizing the latest systematic research findings and corresponding environmental data, a niche model was developed to offer theoretical support for exploring the potential geographical distribution and diversity of liverwort resources. A total of 55,427 liverwort specimens were collected in China, resulting in the recording of 1212 species belonging to 169 genera and 63 families. However, there are imbalances in the distributions of liverwort data among different groups, collection units, and geographical areas, with families such as Lejeuneaceae, Porellaceae, and Plagiochilaceae having the highest number of specimens. Similarly, genera such as Porella, Frullania, and Horikawaella were well represented. Remarkably, 125 species had specimen counts exceeding 100. Unfortunately, approximately 51.77% of the species had fewer than 10 recorded specimens. There were four obvious peaks in the collection years of the bryophyte specimens in China, among which the largest collection occurred from 2010 to 2023. Notably, the number of specimens collected at different stages closely aligned with the history of taxonomic research on liverworts in China. The results of the integrity of the liverwort collection indicate that there is insufficient representation of some families and genera, with a concentration of common and widely distributed large families and genera. Tropical and subtropical humid areas are key regions for liverwort diversity, with water and temperature being the primary environmental factors influencing their geographical distribution. The specific temporal and spatial data of species recorded from plant specimens will enhance the study of species diversity, comprehensive protection, and sustainable utilization. Additionally, these data will contribute to the investigation of large-scale biodiversity distribution patterns and the impact of global change on diversity.

The objective of this study was to evaluate the genetic diversity among traditional common bean accessions through morphological descriptors and molecular markers. Sixty-seven common bean accessions from the Germplasm bank of the Instituto Federal of Espírito Santo—Campus de Alegre were evaluated. For this, 25 specific morphological descriptors were used, namely 12 quantitative and 13 qualitative ones. A diversity analysis based on morphological descriptors was carried out using the Gower algorithm. For molecular characterization, 23 ISSR primers were used to estimate dissimilarity using the Jaccard Index. Based on the dendrograms obtained by the UPGMA method, for morphological and molecular characterization, high genetic variability was observed between the common bean genotypes studied, evidenced by cophenetic correlation values in the order of 0.99, indicating an accurate representation of the dissimilarity matrix by the UPGMA clustering. In the morphological characterization, high phenotypic diversity was observed between the accessions, with grains of different shapes, colors, and sizes, and the accessions were grouped into nine distinct groups. Molecular characterization was efficient in separating the genotypes in the Andean and Mesoamerican groups, with the 23 ISSR primers studied generating an average of 6.35 polymorphic bands. The work identified divergent accessions that can serve different market niches, which can be indicated as parents to form breeding programs in order to obtain progenies with high genetic variability.
Study on the Diffusion Characteristics of Polymer Grouting Materials Applied for Crack Filling in Underground Mines Based on Numerical Simulation and Experimental Methods
Authors: Zhang Xuanning , Wang Ende
Published: September 2024

Polymer grouting materials are increasingly used in the filling of mine fissures. Unlike conventional inorganic grouting materials, the self-expansion of polymers adds complexity to their diffusion process within the crack. The objective of this research was to examine how polymer grouting material spreads in cracks at ambient temperatures and pressure. The investigation involved conducting grouting tests and performing numerical fluid simulation calculations using the finite-volume method in the computational fluid dynamics software, ANSYS FLUENT 2022 R1. The fluid volume approach was employed to determine the boundary between fluid and air and to ascertain the variation patterns of density in the slurry and the fracture system. This study applied the principles of fluid mechanics to investigate the patterns of variation in the physical characteristics of polymer grouting materials, including their density, pressure, flow velocity, and movement distance, during the diffusion process. The results indicated that the density of the polymer grouting material decreased exponentially over time throughout the diffusion process. With the increase in the grouting’s volume, the grout’s pressure and the permeable distance of the grout increased. The slurry’s pressure near the grouting hole exceeded the other points’ pressure. The physical parameters of the slurry were numerically simulated by ANSYS FLUENT 2022 R1 software, and the results were compared with the experimental data. After comparing the numerical simulation results with the test data, it was clear that the numerical simulation method was superior in accurately predicting the distribution pattern of each parameter of the polymer slurry during diffusion. The grouting volume, pressure distribution, and real-time change in the position of the flow of slurry could be efficiently determined through numerical calculation and simulated grouting tests. This work can offer valuable information for designing polymer grouting materials used in underground mine fissures.
Enhancing Active Disturbance Rejection Control for a Vehicle Active Stabiliser Bar with an Improved Chicken Flock Optimisation Algorithm
Authors: Tang Zhenglin , Zhao Qiang , Pham Duc Truong , Zhang Xuesong
Published: September 2024

An active stabiliser bar significantly enhances the anti-roll capabilities of vehicles. The control strategy is a crucial factor in enabling the active stabiliser bar to function effectively. This paper investigates an active disturbance rejection control (ADRC) strategy. Given the numerous parameters of the ADRC and their significant mutual influence, optimising these parameters is challenging. To address this, an improved chicken flock optimisation algorithm is proposed to optimise the ADRC parameters and enhance its performance. First, a three-degree-of-freedom dynamic model of the vehicle is established, and an active disturbance rejection control-based optimisation model utilising a chicken flock optimisation algorithm is constructed. To tackle the issues of getting stuck in local optima and low precision when dealing with complex problems in the traditional chicken flock optimisation (CFO) algorithm, several strategies, including improved Lévy flight, have been adopted. Subsequently, the twelve parameters of the ADRC are optimised using the improved chicken flock optimisation algorithm. Comprehensive testing on multiple benchmark functions demonstrates that the improved chicken flock optimisation (ICFO) algorithm is distinctly superior to other advanced algorithms in terms of solution quality and robustness. Simulation results show that the ICFO-ADRC controller is significantly superior. In four different complex road condition tests, the ICFO-ADRC controller shows an average performance improvement of 8% compared to the fuzzy PI-PD controller, an average improvement of 82% compared to the non-optimised ADRC controller, and an average improvement of 18% compared to the CFO-ADRC controller. Our findings confirm that this paper was able to provide new solutions for vehicle stability control whilst opening up new possibilities for the application of metaheuristic algorithms.
Electricity Generation at Gas Distribution Stations from Gas Surplus Pressure Energy

Published: September 2024

At gas distribution stations (GDSs), the process of throttling (pressure reduction) of natural gas occurs on gas pressure regulators without generating useful energy. If the gas expansion process is created in a turbine, to the shaft where an electric generator is connected, then electricity can be obtained. At the same time, the recycling of secondary energy resources is provided, which is an important component in the efficient use of natural resources. The obtained electric power can be supplied to the external power grid and/or used for the GDS’s own needs. The process of generating electricity at the GDS from gas overpressure energy is an environmentally friendly, energy-saving technology that ensures an uninterrupted, autonomous operation of the GDS in the absence of an external energy supply. The power needs of a GDS with regard to electricity are relatively small (5 ÷ 20 kW). Expansion in throttling devices or turbine flow paths leads to gas cooling with a possible hydrate formation. It is prevented via gas preheating or vortex expansion equipment that keeps the further gas temperature at a necessary level. Turbogenerators can be created on the basis of vortex expansion turbomachines, which have many advantages compared to turbomachines of other types. This article studies how gas pressure (outlet: gas distribution station) and gas preheating (inlet: vortex expansion machine) influence turbogenerator parameters. Nine turbogenerator variants for the power needs of gas distribution stations have been assessed.
Before the Fire Burns: Trials for Superstition, Magic, and Witchcraft in Sixteenth-Century Bologna
Authors: Dall’Olio Guido
Published: September 2024

This article investigates the factors that provoked the trial and death sentence of four witches in Bologna in 1559. That is, it aims to elucidate how a witch hunt (albeit a small one) was triggered in a context where demonology was present, but the persecution of witchcraft had been kept at a relatively moderate level (and continued to be so after that). Scholarly contributions on witchcraft and witch hunts are now innumerable, but in general, scholars have focused on the social relations between the alleged witches and the community in which they lived, on the theological culture of the judges, or even on the deep roots of the sabbath. An analysis of a series of trials for magical and superstitious practices held in Bologna shortly before the 1559 convictions reveals how it was possible to move from simple sorcery to actual witchcraft. This transition was accomplished both because of the malefic nature of some of the spells practiced by the defendants and because of the intervention of diocesan judges who, for various reasons, were more determined than their predecessors to prosecute witchcraft harshly. Although the link between simple superstition and witchcraft has already been explored to some extent, it emerges with particular clarity in these events.
Association between Thyroid Profile Levels and Lymph Node Metastasis in Papillary Thyroid Carcinoma: A Retrospective Study
Authors: Hsieh Yu-Shan , Yang Ting-Teng , Hsu Chung-Huei , Lin Yan-Yu
Published: September 2024

Background: Thyroid cancer is the most common endocrine carcinoma, accounting for 3.26% of all cancers. The most histologically, well-differentiated thyroid cancer is papillary thyroid carcinoma (PTC). Although PTC is regarded as an indolent tumor, a portion of the cancer cells metastasize to lymph nodes around the thyroid gland. Lymph node metastasis (LNM) is a critical risk factor for tumor recurrence in PTC, which strongly affects disease prognosis and the quality of life. Methods: This study aims to examine how differences in the level of the thyroid profile and other risk factors may influence LNM incidence in patients with PTC in Taiwan. We carried out a single-center retrospective study. These PTC patients were retrospectively reviewed by the Department of Endocrinology from 2016 to 2019. A total of 165 patients were included in our research. Results: The findings revealed a close relationship with the level of free thyroxine (FT4), the level of the thyroid-stimulating hormone (TSH), and lymph node metastases. The correlation in terms of FT4 (p = 0.005) and TSH (p = 0.417) with LNM was found as a result of the univariate regression analysis. In the multiple regression analysis, the findings revealed a close relationship between LNM, FT4 (p < 0.001), and TSH (p = 0.008). Conclusions: Although the predictability of the TSH should be examined further, the association between LNM and FT4 or TSH should not be ignored. The results could help guide decision-making and patient counseling, using the level of serum FT4 or the TSH as a possible predictive factor of the LNM in PTC.
Visual-Inertial RGB-D SLAM with Encoder Integration of ORB Triangulation and Depth Measurement Uncertainties
Authors: Ma Zhan-Wu , Cheng Wan-Sheng
Published: September 2024

In recent years, the accuracy of visual SLAM (Simultaneous Localization and Mapping) technology has seen significant improvements, making it a prominent area of research. However, within the current RGB-D SLAM systems, the estimation of 3D positions of feature points primarily relies on direct measurements from RGB-D depth cameras, which inherently contain measurement errors. Moreover, the potential of triangulation-based estimation for ORB (Oriented FAST and Rotated BRIEF) feature points remains underutilized. To address the singularity of measurement data, this paper proposes the integration of the ORB features, triangulation uncertainty estimation and depth measurements uncertainty estimation, for 3D positions of feature points. This integration is achieved using a CI (Covariance Intersection) filter, referred to as the CI-TEDM (Triangulation Estimates and Depth Measurements) method. Vision-based SLAM systems face significant challenges, particularly in environments, such as long straight corridors, weakly textured scenes, or during rapid motion, where tracking failures are common. To enhance the stability of visual SLAM, this paper introduces an improved CI-TEDM method by incorporating wheel encoder data. The mathematical model of the encoder is proposed, and detailed derivations of the encoder pre-integration model and error model are provided. Building on these improvements, we propose a novel tightly coupled visual-inertial RGB-D SLAM with encoder integration of ORB triangulation and depth measurement uncertainties. Validation on open-source datasets and real-world environments demonstrates that the proposed improvements significantly enhance the robustness of real-time state estimation and localization accuracy for intelligent vehicles in challenging environments.
Translating Values into Quality: How We Can Use Max Weber’s Ethic of Responsibility to Rethink Professional Ethics
Authors: Mieg Harald A.
Published: September 2024

A risk-based reinterpretation of Weber’s ethic of responsibility can resolve core problems of professional ethics (the role of values, the multilevel problem, etc.) and address current issues—such as the social responsibility of professions or the accountability of professionals. From this perspective, professions as organizations and professionals as their individual members share and distribute responsibility (and risk) in that the primary responsibility of a profession is to provide domain-specific quality standards, while that of individual professionals is to be able to justify service against those standards on a case-by-case basis. In this way, as argued in the paper, professionalism translates (sometimes conflicting) values into a case-specific quality.

Authors: Martín-Ruiz Isaías , Robles-Sánchez María-José , Wallace Agustín
Published: September 2024

The prevalence of mental health problems in adolescence is high, and it would appear that certain conditioning factors such as having a Specific Learning Disability (SpLD), the application of educational measures (repeating a school year), or gender can have an impact on the socioemotional development of adolescents. However, we do not yet have a clear picture of the role played by each variable or whether there are interactions between them. Therefore, the objective of this study is to analyse the effect of these independent variables on internalising problems (anxiety and depression) and on personal resources (self-esteem, social competence, and awareness of the problem). The sample is composed of 80 students, 40 with SpLD and 40 control, aged between 12 and 17 years old, matched in terms of age and gender. The results indicate that the variables Specific Learning Disabilities and educational measures have a negative impact on internalising problems and personal resources of adolescents, while there is no significant effect with respect to gender. In addition, we identified interactions between having SpLD and being held back a year. We therefore call into question the negative impact of repeating a school year according to the condition.

Published: September 2024

Estrogens in river systems can significantly impact aquatic ecosystems. This study aimed to investigate the multiphase partitioning of estrogens in Wulo Creek, Taiwan, which receives animal feedlot wastewater, to understand their distribution and potential environmental implications. Water samples were separated into suspended particulate matter (SPM), colloidal, and soluble phases using centrifugation and cross-flow ultrafiltration. Concentrations of estrone (E1), 17β-estradiol (E2), and estriol (E3) in each phase were analyzed using LC/MS/MS. Partition coefficients were calculated to assess estrogen distribution among phases. Estrogens were predominantly found in the soluble phase (85.8–87.3%). The risk assessment of estrogen equivalent (EEQ) values suggests that estrogen concentration in water poses a higher risk compared to SPM, with a majority of the samples indicating a high risk to aquatic organisms. The colloidal phase contained 12.7–14.2% of estrogens. The log KCOC values (4.72–4.77 L/kg-C) were significantly higher than the log KOC and log KPOC values (2.02–3.40 L/kg-C) for all estrogens. Colloids play a critical role in estrogen distribution in river systems, potentially influencing their fate, transport, and biotoxicity. This finding highlights the importance of considering colloidal interactions in assessing estrogen behavior in aquatic environments.

Background: Experimental models of neurocysticercosis (NCC) are helpful for an improved understanding of the pathophysiological mechanisms of human diseases and for testing novel therapeutic approaches. Controlling inflammation without reducing the effectiveness of anthelmintics is an important challenge in treating neurocysticercosis. This study investigates the effects of currently used drugs (Albendazole and Dexamethasone) in treating murine extraparenchymal NCC. Methods: Twenty-two rats were inoculated with Taenia crassiceps in the subarachnoid space. The animals underwent magnetic resonance imaging to ascertain the success of infection 3 months after inoculation. The infected animals were randomly assigned to one of the three groups (five rats each): control (no treatment), Albendazole (ABZ), or Albendazole + Dexamethasone (ABZ + DXM) for 14 days. The animals were subsequently euthanised for morphological assessment 2 weeks after the end of treatment. Results: Macroscopically integrated cysts were found in all animals. The ABZ + DXM animals demonstrated lower ventricular sizes, lymphocyte infiltration rates, and immunopositivity for IL-6, with statistical differences in lymphocytes within the arachnoid region. Conclusions: This experimental model, which has previously shown similarities to human infections, is also helpful in reproducing the morphological changes upon treatment with Albendazole and Dexamethasone.

Published: September 2024

Inducing T lymphocyte (T-cell) activation and proliferation with specificity against a pathogen is crucial in vaccine formulation. Assessing vaccine candidates’ ability to induce T-cell proliferation helps optimize formulation for its safety, immunogenicity, and efficacy. Our in-house vaccine candidates use microparticles (MPs) and nanoparticles (NPs) to enhance antigen stability and target delivery to antigen-presenting cells (APCs), providing improved immunogenicity. Typically, vaccine formulations are screened for safety and immunostimulatory effects using in vitro methods, but extensive animal testing is often required to assess immunogenic responses. We identified the need for a rapid, intermediate screening process to select promising candidates before advancing to expensive and time-consuming in vivo evaluations. In this study, an in vitro overlay assay system was demonstrated as an effective high-throughput preclinical testing method to evaluate the immunogenic properties of early-stage vaccine formulations. The overlay assay’s effectiveness in testing particulate vaccine candidates for immunogenic responses has been evaluated by optimizing the carboxyfluorescein succinimidyl ester (CFSE) T-cell proliferation assay. DCs were overlaid with T-cells, allowing vaccine-stimulated DCs to present antigens to CFSE-stained T-cells. T-cell proliferation was quantified using flow cytometry on days 0, 1, 2, 4, and 6 upon successful antigen presentation. The assay was tested with nanoparticulate vaccine formulations targeting Neisseria gonorrhoeae (CDC F62, FA19, FA1090), measles, H1N1 flu prototype, canine coronavirus, and Zika, with adjuvants including Alhydrogel® (Alum) and AddaVax™. The assay revealed robust T-cell proliferation in the vaccine treatment groups, with variations between bacterial and viral vaccine candidates. A dose-dependent study indicated immune stimulation varied with antigen dose. These findings highlight the assay’s potential to differentiate and quantify effective antigen presentation, providing valuable insights for developing and optimizing vaccine formulations.

Published: September 2024

Porcine rotavirus (PoRV) is a significant enteric pathogen causing gastroenteritis in piglets, which causes huge economic loss to the Chinese pig industry. In this study, six porcine rotavirus A strains were isolated from three adjacent sow farms belonging to the same company within one year, which suffered severe diarrhea outbreaks. AHBZ2303 (G11P[7]) and AHBZ2305 (G9P[23]), AHBZ2304 (G9P[23]) and AHBZ2312 (G4P[6]), AHBZ2310 (G9P[23]) and AHBZ2402 (G5P[23]) were isolated from Farm A, B and C, respectively. All six isolates were related to human rotavirus through complete genome analysis, suggesting the potential cross–species infection between humans and pigs. Evolutionary analysis revealed that AHBZ2303 and AHBZ2304 likely emerged simultaneously in Farm A and B, and then AHBZ2304 was introduced to Farm A and C, leading to the emergence of AHBZ2305 and AHBZ2310. Recombination and large variation were identified for AHBZ2312 and AHBZ2402. These findings provided insights into the transmission and evolution of PoRV among farms and underscored the need for enhanced monitoring to mitigate the risk of outbreaks from novel variants.

This study explores the obstacles to electric vehicle (EV) adoption in Indonesia, focusing on technological, environmental, economic, and regulatory factors. Despite government initiatives, such as the Presidential Regulation 55 of 2019, intended to encourage the adoption of EVs and mitigate air pollution, the EV market share in Indonesia remains low, at 1.47%. The main challenges include inadequate charging infrastructure, limited public revenue, and financial constraints. This research highlights the need for improved government policies, incentives for producers, and increased public awareness to encourage EV adoption. Factors influencing consumer decisions include operational costs, environmental concerns, and the availability of charging stations. Key findings suggest that electric motorcycle users have a lower understanding of technology than electric car users, with particular attention to initial costs, maintenance costs, and the accessibility of charging infrastructure. This study recommends that manufacturers and policymakers consider the different preferences of electric car and motorcycle users in their EV adoption promotion strategies. The study seeks to elucidate the determinants affecting EV adoption in Indonesia and propose potential solutions to accelerate the transition to electric mobility.
Effect of Cell-to-Cell Internal Resistance Variations on the Thermal Performance of Lithium-Ion Batteries for Urban Air Mobility
Authors: Xin Kuo , Lee Geesoo
Published: September 2024

This study examines the thermal behavior of lithium-ion battery modules intended for Urban Air Mobility (UAM), a forthcoming urban transport system designed to facilitate efficient and secure passenger and cargo transport within city centers. UAM applications necessitate batteries with high energy densities capable of sustaining elevated discharge rates during critical phases such as takeoff and landing. The battery module evaluated in this study comprises four cells arranged in series and configured as a submodule for UAM applications. A three-dimensional thermal model was utilized to analyze the impact of external temperature fluctuations and high discharge rates on the performance of the battery module. The numerical findings indicated considerable variations in temperature and internal resistance among the cells, especially under high discharge rates at low temperatures, with a maximum temperature deviation of 32.952 °C observed at an 8 C discharge rate. These thermal non-uniformities were attributed to variations in cell capacity and internal resistance, which were amplified by manufacturing inconsistencies and operational conditions. The study underscores the necessity of robust thermal management strategies to mitigate the risk of thermal runaway and ensure the operational safety and reliability of UAM systems. The results emphasize the critical role of advanced Battery Management Systems (BMS) in monitoring and controlling cell voltage and temperature to achieve consistent performance across the battery module. This research contributes valuable insights into the design of more efficient and reliable battery modules for UAM, highlighting the importance of addressing cell-to-cell performance discrepancies to enhance overall module efficacy and durability.

Modern education involves the active use of digital learning tools, which may have potential health risks for children and adolescents. Thus, the use of interactive panels (IP) in educational organizations, which everywhere replace traditional blackboards, causes a negative impact on the air parameters of classrooms: temperature rises, humidity decreases, and an imbalance in the content of positive and negative polarity aeroions appears. As you know, these indicators affect a person’s well-being, determine their performance, which determines the need to optimize classroom air. Comparative studies of the microclimate and aeroion composition of the air of classes equipped with IP have been carried out in the process of applying various methods of air optimization: additional wet cleaning, the use of an air humidifier and an air ionizer with a humidification function. Measurements were carried out in the dynamics of the educational organization’s school day: in the first, third and fifth lessons. The use of a humidifier and an ionizer helps to maintain the temperature, relative humidity and aeroionic composition of the air at a relatively stable level. In the absence of additional means of optimizing the air environment in classrooms with IP, the temperature, humidity and content of aeroions already in the middle of the school day go beyond the limits of hygienic standards. During additional wet cleaning, an almost similar pattern is observed, with the exception of the air humidity level, the decrease of which can be somewhat delayed. The results obtained indicate the expediency of optimizing classroom air when using an interactive panel: the use of a humidifier and/or an air ionizer contributed to maintaining the studied parameters practically within the normalized values throughout the school day.

Retention of all or part of the weapon following a non-missile penetrating spinal injury is a rare occurrence. The authors report a case of thoracic spinal cord stab injury in a young man. The patient presented with a knife blade lodged in his back and with Brown-Sequard-plus syndrome. At surgery, the wound with the knife in situ was explored and the knife was removed. Although the wound healed without evidence of cerebrospinal fluid leakage or infection, he developed a complete neurologic deficit post-operatively. This was an unlikely outcome for incomplete spinal cord injury resulting from non-missile penetrating spinal injury, historically known to have a favourable outcome. Pre-operatively, patients with incomplete neurological injury following penetrating spine injury with the retained foreign body should be specifically counselled on the possibility of a worsened neurological outcome after surgical intervention.
Feasibility and safety of using the radial artery approach for the Wada test

Published: September 2024

The Wada test is used to lateralize the dominant hemisphere in epilepsy patients prior to surgery. Either amobarbital, methohexital, or propofol is injected via a transfemoral catheter into a unilateral carotid artery, briefly suppressing the ipsilateral cerebral hemisphere to allow functional evaluation of the opposite side. Here, we highlight and propose a radial artery approach for the Wada test, allowing easier arterial access, better patient comfort, and ample procedural efficacy.

Patients with traumatic brain injury experience complications and sequelae that lead to dysfunction and an uncertain prognosis. Brain injury induces a state of hypermetabolism and hypercatabolism, increasing the energy requirements of patients and predisposing them to malnutrition if appropriate nutritional support is not initiated early. To investigate this issue, we conducted a narrative review through December 2022. Poor nutrition in neurosurgical patients elevates mortality rates and significantly amplifies the risk of post-surgical complications. Recent studies have revealed that patients with traumatic brain injury experience an increase in metabolism of up to 250%, resulting in significant nitrogen loss. These patients should consume no less than 15% of total calories in the form of protein, with amino acid intake approaching 2 g/kg based on the patient's ideal weight being beneficial. Studies have compared the effectiveness of parenteral and enteral nutrition in these patients, with enteral nutrition providing superior benefits. Enteral nutrition is consistent with human physiology and supports a healthy gastrointestinal tract, modulates the immune system, and reduces the risk of liver cholestasis, which is higher in parenteral nutrition.

Published: September 2024

Background:  Basal Ganglia calcification is now being diagnosed with increasing frequency with the widespread application of computed tomography (CT) scan in clinical practice. One of the rare causes of bilateral basal ganglia calcification is post-irradiation sequelae. So far, there are a total of 11 reported cases of post-radiotherapy basal ganglia calcification.
Case report: Here, we report another case of bilateral basal ganglia calcification following radiotherapy for cerebral metastasis from Ca- ovary along with a review of the other reported cases. The exact pathogenesis of this condition is not clear. It appears, however, to be related to radiation vasculitis of the small vessels of the brain with resultant hyalinization and calcification. Conclusions: A long-term follow-up study would be necessary to evaluate the significance and implication of post-irradiation calcification of the grey matter.

Background: This study focuses on comparing and predicting the number of perforating arteries (PA) of the anterior communicating artery (AcoA) preoperatively by using cerebral angiographic studies and perioperative surgical observations.
Materials and methods: From April 2010 - March 2012, 13 patients with subarachnoidal haemorrhages undergoing surgery to repair an AcoA aneurysm were evaluated with digital subtraction angiography (DSA) and perioperative surgical observations available for the study.
Each patient’s number of PA arising from AcoA was investigated based on DSA imaging. DSA examinations were retrospectively evaluated by three neuroradiologists. The perioperative surgical observations were evaluated together by two neurosurgeons who performed surgical procedures.
Results: The number of PA of AcoA was classified into four groups. Group 1: No PA; Group 2: PA 1 to 3; Group 3: PA 4 to 6; Group 4: PA> 6. In our study, in 6 of 13 patients (46.1%) three radiological evaluations were in accordance with each other; in 8 (61.5%) cases the number of PA found in surgical observation was higher than the number obtained from at least two radiologic examinations. In all radiological examinations, PA numbers were most commonly (%61.5) classified as Group 2 (PA numbers between 1-3); in 76.9% of cases, the number of PA found in surgical observation was equal or more than those of radiological evaluations. Additionally, in 5 (38.4%) cases, the number of PA found in surgical observation was higher than the number of those radiologic examinations. Conclusion: We found that the number of perforating arteries of AcoA segment obtained from the surgical observation is slightly higher than the number obtained from the preoperative DSA assessment.
