Summary: The study found that intrapulmonary concomitant lesions were more common in patients with non-neoplastic ground-glass nodules (GGNs) compared to those with neoplastic GGNs. Multiple solid nodules, patchy ground-glass opacity/consolidation, and fibrosis/calcification were more frequently observed in non-neoplastic GGNs. Including the presence of concomitant lesions in the predictive model improved the accuracy of differentiating non-neoplastic and neoplastic GGNs.

Summary: X-CC9 system enables selective activation of therapeutic agents at tumor sites through X-ray guidance and remote control, leading to M2-to-M1 repolarization within the tumor microenvironment. This strategy significantly improves antitumor efficacy and induces robust immune responses.

Summary: NK cells, as innate lymphoid cells, play key roles in immune surveillance of tumors with cytotoxic capacity. Increasing evidence shows that NK cell anti-tumor response is influenced by bidirectional interactions with myeloid cell subsets such as dendritic cells and macrophages in the tumor microenvironment. This crosstalk can impact NK cell survival, activation, differentiation, and function, ultimately affecting the efficacy of immunotherapeutic approaches for cancer.

Summary: This review provides an update on the molecular mechanisms of the avian paramyxovirus, Newcastle Disease Virus (NDV), in its anti-neoplastic and immune stimulatory properties. It highlights the potential of NDV as a unique oncolytic virus that can overcome therapy resistance in human cancer cells.

Summary: The study evaluated the radiosensitivity of Bambara groundnut varieties to acute and chronic gamma irradiations, determining their lethal doses and growth reduction doses. Lower gamma irradiation doses were found to promote growth, development, and survival rates of Bambara groundnut.

Summary: The study demonstrates that the dose rate of high-energy X-rays can influence their relative biological effectiveness, resulting in severe damage during radiation. The results underline the importance of multiparametric analysis approaches in providing an accurate evaluation of the outcomes of irradiated cells in cases where standard assays are not feasible.

Summary: Modern techniques of radiotherapy, such as fractioned radiotherapy, require the application of low doses of ionizing radiation for effective treatment of cancer cells. Research shows that the response of cancer cells to radiation depends on both the dose and the time elapsed after irradiation, emphasizing the importance of considering both factors in studying the effects of ionizing radiation.

Summary: Cells have different sensitivity to ionising radiation depending on their phase during the cell cycle. Low doses of radiation can induce various delayed and non-targeted effects, including bystanders and hyper-radiosensitivity. The hyper-activation of DNA repair mechanisms due to excessive induction of DNA double-strand breaks is thought to be responsible for the hyper-radiosensitivity phenomenon. This phenomenon modifies the Linear Quadratic model and is observed at low doses below 1 Gy of radiation.

Summary: The study showed that dopamine's impact on membrane lipids depends on whether it is exposed to X-ray irradiation, unlike 2-phenylethylamine which has no effect on membrane lipids regardless of irradiation. Dopamine exhibits strong antioxidant capacity, but it is also oxidized to aminochrome upon X-ray irradiation.

Summary: Anti-thymocyte globulin (ATG) is commonly used as an induction regimen to prevent acute rejection after solid organ transplantation, but the optimal dose for Asian kidney recipients is unclear. A retrospective cohort study in South Korea compared different induction regimens in 4579 adult renal transplantation patients. The study found that high-dose ATG induction (>4.5 mg/kg) showed better graft and patient survival outcomes compared to basiliximab and low-dose ATG induction in Asian kidney transplant patients.

Summary: This study aimed to investigate the effect of locally fractionated radiotherapy on fibrosis and hyposalivation by monitoring cytokine levels. The results showed significant fibrosis in the submandibular salivary gland and reduced saliva production after irradiation. Pro-inflammatory cytokines IL-1 alpha, TNF, TIMP1, G-CSF, KC, and MIP-1 alpha were found to have increased levels in saliva and a strong correlation with late endpoints. Cytokine expression in saliva, particularly IL-1 alpha, was identified as a good biomarker for assessing salivary gland damage.

Summary: The use of ionizing radiation for medical purposes is increasing, especially in diagnostic imaging such as computed tomography (CT). However, this also leads to increased exposure to radiation for both patients and healthcare professionals. CT scans, although providing detailed and high-quality images, contribute to a significant portion of the medical radiation dose accumulated by the patient. This study aims to estimate the absorbed dose in sensitive organs due to scattered radiation during a chest CT.

Summary: Radiation measurements are crucial in various fields, and the development of cost-effective, sensitive, and compact radiation detection devices has improved its application. This study focuses on the performance of a low-cost X-ray radiation detector based on extended gate field effect transistors (EGFET). Different thicknesses of Al-doped Zinc oxide (AZO) were examined for sensitivity following X-ray irradiation. The response was analyzed in terms of threshold voltage shift, and the dependence on material composition and thickness was evaluated. These findings suggest that thin films could be a cost-effective alternative for real-time, room-temperature radiation detectors.

Summary: This study evaluated the radiation doses from chest x-rays for 240 pediatric patients from four Palestinian hospitals, using theoretical calculations and estimating absorbed organ doses. Effective doses were estimated for five age groups, showing significant variations in doses among hospitals for the same age group and x-ray examination.

Summary: The study demonstrated that the vitamin B-3 derivative 1-methyl nicotinamide significantly prolonged the survival of mice irradiated at high doses of gamma rays when administered 7 days post-irradiation. Another vitamin B-3 derivative, 1-methyl-3-acetylpyridine, also showed some level of effectiveness, particularly after the highest dose of radiation. These pro-survival effects may be related to anti-inflammatory and anti-thrombotic properties of the vitamin B-3 derivatives.
