Fungi respond to light irradiation by forming conidia and occasionally synthesizing mycotoxins. Several light wavelengths, such as blue and red, affect the latter. However, the relationship between light irradiation and mycotoxin synthesis varies depending on the fungal species or strain. This study focused on aflatoxin (AF), which is a mycotoxin, and the types of light irradiation that increas...

The effects of irradiation on different cell compartments in the submandibular gland were analyzed in adult C57BL/6 mice exposed to X-ray irradiation and followed up for 10 days. Apoptosis was quantified using the terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-digoxigenin nick end labeling method (TUNEL). Cell proliferation was detected using immunohistochemistry for proliferating ce...

INTRODUCTION The irradiation of blood components is used to inactivate T-lymphocytes to prevent transfusion-associated graft-versus-host (GVH) disease in susceptible recipients. X-irradiation can be used as an alternative to gamma irradiation and does not involve the use of a radioactive source. This study investigated the effect of X-irradiation on the quality of various red cell concentrates ...

PURPOSE AND BACKGROUND Conventional early breast cancer treatment consists of a lumpectomy followed by whole breast radiation therapy. Accelerated partial breast irradiation (APBI) is an investigational approach to post-lumpectomy radiation for early breast cancer. The purpose of this study is to compare four external beam APBI techniques, including tomotherapy, with conventional whole breast i...

Total body irradiation is performed as a preconditioning regimen to inhibit graft-versus-host disease after bone marrow transplantation and to eradicate remaining tumor cells. However, these regimens result in delayed secondary sex characteristics and failure of ovarian function recovery, leading to amenorrhea and infertility. Herein, we report a case of an 11-year-old girl diagnosed with acute...

Sublethal doses of irradiation enhance the invasiveness of human malignantglioma cells. This can be inhibited by subtoxic concentrations of temozolomide (TMZ) but not by lomustine. Antagonism of irradiation-induced motility by TMZ is associated with the prevention of irradiation-induced alpha(v)beta(3)-integrin, matrix metalloproteinase-2 and MT1-matrix metalloproteinase-expression. Irradiation...

We evaluated the efficacy of contrast-enhanced ultrasound for assessing tumors after irradiation with sub-threshold focused ultrasound (FUS) ablation in pancreatic cancer xenografts in nude mice. Thirty tumor-bearing nude mice were divided into three groups: Group A received sham irradiation, Group B received a moderate-acoustic energy dose (sub-threshold), and Group C received a high-acoustic ...

Ninety three children (51 boys, 42 girls) who had been treated for brain tumours not affecting the hypothalamopituitary axis, were studied for evidence of gonadal dysfunction. All had received cranial irradiation, 59 spinal irradiation, and 28 adjuvant chemotherapy. Mean age at treatment was 6.3 years (range 1.5-15). Mean follow up after completion of radiotherapy was 8.5 years (range 1-27). Pr...

For women undergoing breast-conserving surgery, recent reports suggest that in selected cases accelerated partial breast irradiation may yield results equal to that of whole breast irradiation. Over 31 months, 19 patients underwent accelerated partial breast irradiation using the MammoSite as the sole radiation treatment following breast-conserving surgery. Seventeen patients had the MammoSite ...

Breast conservation therapy (BCT), consisting of local excision of the breast tumor to achieve negative margins followed by whole breast irradiation, is standard treatment for early-stage breast cancer. The conventional radiotherapy course treats the entire breast, typically followed by a boost to the tumor bed over six to seven weeks. While the efficacy and cosmetic outcomes of conventionally ...
