Background: Differences in radiation-induced lymphopenia and prognosis between methods of radiotherapy (RT) for brain metastases remain unclear.

Methods: In this retrospective analysis of patients who underwent whole-brain radiotherapy (WBRT) or stereotactic radiosurgery/radiotherapy (SRS/SRT) for brain metastases, baseline total lymphocyte count (TLC) data were obtained within 2 weeks before RT initiation. Follow-up TLC data were evaluated at 0-2, 2-4, and 4-8 weeks after RT completion.

Background: This study aimed to reveal the long-term outcomes and late toxicities (> 5 years) after definitive intensity-modulated radiation therapy (IMRT) in patients with nasopharyngeal carcinoma (NPC).

Methods: Data from 43 patients (median age, 55 years; range, 17-72 years) with NPC who underwent definitive IMRT between 2001 and 2018 were analyzed. All patients were alive and disease-free 5 years after IMRT.

Background: Hypothyroidism is a common adverse event after radiotherapy for head and neck tumors and the incidence need to be re-evaluated because of using intensity-modulated radiotherapy (IMRT).

Aims/objectives: Confirm the dose-volume effect of IMRT for pharyngeal cancer on hypothyroidism.

Materials And Methods: This was a retrospective analysis of patients underwent IMRT for pharyngeal cancer from June 2011 to May 2018.

Jujube (Ziziphus jujuba Mill.), a traditional folk medicine and functional food in China and South Korea, is known for its beneficial properties, which include anti-cancer, anti-oxidative, and anti-obesity effects. To assess the anti-hyperglycemic effect of jujube in this study, we investigated the glucose uptake-promoting activity of jujube in rat L6 myotubes.

Background: Clinical results of computed tomography (CT) simulations and [F]-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/CT simulations were compared retrospectively.

Materials And Methods: Between 2006 and 2011, [F]-FDG PET/CT simulation was performed on 68 consecutive patients with pharyngeal cancers (PET/CT group). As an historical control, conventional CT simulation was performed on 56 consecutive patients with pharyngeal cancer between 2000 and 2006 (CT group).

Background: New treatment strategies for prostate cancer have recently been developed, but multiple malignancies remain a major concern. The aim of this study was to evaluate the characteristics of multiple malignancies and to analyze the risk of secondary malignancies after radiotherapy for prostate cancer.

Methods: From 2000 to 2011, 150 patients with prostate cancer were treated with curative radiotherapy in our department.

The single-electron circuit and nanostructure described in this paper are designed for stochastic associative processing, which is an expanded version of ordinary associative memory processing. In stochastic associative processing, the association probability of each stored pattern depends on the similarity between the stored pattern and the input pattern. Such unique processing is useful for sequential stochastic association and for clustering for vector quantization.
