BackgroundOver the past five decades, extensive research has been conducted on lymphoma imaging diagnostics; however, no bibliometric analysis has been performed in this area. Therefore, we undertook a bibliometric analysis to clarify the progress and current state of research in this field.MethodsWe conducted a search of the Web of Science Core Collection database for articles related to imaging diagnosis and lymphoma, focusing exclusively on English-language publications up to June 20, 2024. We analyzed and visualized various aspects, including publication trends, journals, co-authorship networks, countries, institutions, and keywords. To examine research trends in this field, we utilized bibliometric analysis tools such as VOSviewer, CiteSpace, and R4.3.3.ResultsFrom 1976 to 2024, a total of 10,410 publications were produced on this topic, with 2021 marking the peak in publication numbers. The most significant contributions in this research area were found in the fields of Radiology, Nuclear Medicine & Medical Imaging, Oncology, and Hematology. The United States, China, and Japan were the leading contributors. Zucca Emanuele ranked first among authors, followed closely by Meignan Michel. In terms of institutions, Assistance Publique Hôpitaux de Paris was the most prominent. The most frequently used keywords included positron emission tomography, computed tomography, and non-Hodgkin’s lymphoma.ConclusionThis study presented a bibliometric analysis of lymphoma imaging diagnosis, highlight showcasing research trends, influential significant studies, and collaborative networks. The analysis identified key contributions to the field and provide insights for future research directions.

Abstract The decrease in tungsten (W) content with the higher ion cyclotron resonance heating (ICRH) power is observed and explained for the first time in a high power injection (Pinj>10MW), high performance (βN~2, βP~2.8, ne/nGW~80%, fBS~60%) H-mode discharge on experimental advanced superconducting tokamak (EAST). Unlike the previous phenomenon of electron cyclotron resonance heating (ECRH) core W control (Shengyu Shi et al 2022 Nucl. Fusion 62 066031), there is a slight change in the background plasma temperature when higher ICRH is applied, but the toroidal rotational velocity decreases by ~10km/s. Under this condition, the intensity of W unresolved transition array (W-UTA) spectral structure in the region of 45-70 Å (which is composed of W27+-W45+ line emissions) and W44+ density through spectroscopy in the Extreme Ultraviolet (EUV) region decreases markedly. In addition, the poloidal asymmetry of radiation distribution from the tomographic inversions of Soft X-Ray (SXR) emission is reduced obviously. Theoretical modeling results indicate that the reduction in toroidal rotation leads to less W poloidal asymmetry and neoclassical pinch, which is more efficient in alleviating the core W accumulation than the improvement of isotropic hydrogen (H) minority temperature. The effects of isotropic and anisotropic H minority from ICRH on W transport are compared in the simulation lastly.

Background The increasing use of ionizing radiation in clinical environments, particularly during surgeries such as orthopedics and neurosurgery, has heightened concerns about the potential health risks associated with this type of radiation. This issue is particularly relevant for nursing students undergoing training in operating room settings, where they are frequently exposed to various sources of radiation. To effectively implement radiation protection principles, it is crucial to evaluate the knowledge and attitudes of the students toward ionizing radiation. Understanding their level of awareness and beliefs about radiation safety will inform the development of targeted training programs aimed at minimizing exposure and enhancing safety in clinical environments. Objective This study aimed to investigate the level of knowledge, attitudes, and performance of 8th-semester undergraduate anesthesia and operating room nursing students toward radiation protection principles. Methods This cross-sectional study was conducted at the Hamadan University of Medical Sciences in 2024. In this study, students were selected via the census sampling method. The data related to the study were collected from valid questionnaires concerning the participants’ level of knowledge, attitudes, and performance toward ionizing radiation. The data analysis was also conducted at the descriptive and inferential statistics level via SPSS version 16 software. Results The knowledge, attitudes, and performance of the students in both fields were inadequate compared to the ideal standards. Additionally, the mean attitude score toward protective principles was significantly greater among operating room nursing students than anesthesia nursing students (p-value = 0.023). Furthermore, a positive and significant correlation was found between students' Grade Point Average (GPA) and their scores on knowledge and attitudes toward protective principles (r = 0.449, p-value = 0.000 and r = 0.648, p-value = 0.000, respectively). Conclusion This study revealed that the level of knowledge among students regarding ionizing radiation is lower than the desired standards for ensuring safety in clinical environments. As a result, it is essential to implement targeted training courses to enhance students' understanding of the risks associated with ionizing radiation.

Abstract A rapid verticalization to accommodate the citizens of the Metropolitan Region of São Paulo is altering the balance of radiation and atmospheric heat, highlighting the need to understand the impact that green and built infrastructure have on the canopy urban heat island phenomenon. This meteorological phenomenon occurs mainly due to the difference in landscape between urban and rural areas. Hypothetical scenarios with different green profiles were simulated using the WRF model coupled with SLUCM, and their results were compared to the current scenario using numerical data in order to observe the impact of green infrastructure. Comparison using output data showed that the total area of green infrastructure has great potential in reducing the intensity of the canopy urban heat island. The scenario with the largest total area and highest dispersion of green infrastructure recorded average urban temperatures 1.2 °C to 1.9 °C lower than the current scenario. Understanding the behavior of green infrastructure and its benefits is important for the development of municipal public policies that are in line with sustainable goals, and explicitly the relevance of urban parks and squares for local thermal regulation.

Abstract Leukemia is one of the most common cancers in prepubertal girls and adolescents, with advances improving survival rates. However, treatments like chemotherapy and radiation are highly gonadotoxic, often causing ovarian insufficiency, early menopause, infertility, and endocrine disorders. Fertility preservation for young female cancer patients, especially prepubertal girls without mature germ cells, relies heavily on ovarian tissue cryopreservation. Yet, a major concern is the potential presence of leukemic cells within preserved tissue, posing a risk of reintroducing malignancy upon grafting. Additionally, the direct effects of leukemia on ovarian function remain unclear. In this study, we used an acute myeloid leukemia (AML) mouse model to explore leukemia's impact on ovarian function. Leukemic cells infiltrated the ovaries, particularly the stromal regions and granulosa layers of antral follicles, while also being present in the spleen and liver. Despite this infiltration, ovarian structure, follicular counts, and primordial follicle reserves were largely preserved, with the notable absence of corpus luteum indicating impaired ovulation. Furthermore, leukemic infiltration induced inflammatory cytokines TNF-α and COX-2, potentially influencing ovarian health. These findings suggest opportunities for fertility preservation by selectively removing leukemic cells, though risks of malignancy remain. This model offers a platform for advancing fertility-preservation strategies during gonadotoxic cancer therapies.
