BACKGROUND It has not been investigated whether there are associations between urinary iodine (UI) excretion measurements some years apart, nor whether such an association remains after adjustment for nutritional habits. The aim of the present study was to investigate the relation between iodine-creatinine ratio (ICR) at two measuring points 5 years apart. METHODS Data from 2,659 individuals ...
The paternal-allele-specific methylation of the Igf2/H19 imprinting control region (ICR) is established during gametogenesis and maintained throughout development. To elucidate the requirement of the germline passage in the maintenance of the imprinting methylation, we established a system introducing a methylated or unmethylated ICR-containing DNA fragment (ICR-F) into the paternal or maternal...
Mono-allelic expression at the mouse IGF2/H19 locus is controlled by differential allelic DNA methylation of the imprinting control region (ICR). Because a randomly integrated H19 ICR fragment, when incorporated into the genome of transgenic mice (TgM), was allele-specifically methylated in somatic, but not in germ cells, it was suggested that allele-discriminating epigenetic signature, set wit...
BACKGROUND Staphylococcus aureus infections are a major cause of morbidity and mortality worldwide. Clindamycin is widely used in the treatment of staphylococcal infections; however, it is our impression that in the last few years, inducible clindamycin resistance (ICR) has become more prevalent. OBJECTIVE To assess the prevalence of ICR in methicillin-sensitive Staphylococcus aureus (MSSA) i...
Institute of Cancer Research (ICR) mice have been widely used in various research fields including toxicology, oncology, pharmacology, and pharmaceutical product safety testing for decades. However, annual tendency of research papers involving ICR mice in various biomedical fields has not been previously analyzed. In this study, we examined the numbers of papers that used ICR mice as experiment...
Mouse is a commonly used animal in life science studies and is classified as outbred if genetically diverse and inbred if genetically homogeneous. Outbred mouse stocks, are used in toxicology, oncology, infection and pharmacology research. The National Institute of Food and Drug Safety Evaluation (NIFDS; former the Korea National Institute of Health) have bred ICR mice for more than 50 years. W...
Superovulated eggs in (BALB/cxC57BL/6) F1 and ICR (outbred in a closed colony) female mice were fertilized in vitro with spermatozoa obtained from caudal epididymides of ICR males. Air-dried chromosome preparations were made from colcemid-primed 1-cell eggs and stained by the C-banding method. The fertilization rate was lower in F1 eggs than in ICR eggs (88 vs. 92%, P<0.02). The incidence of me...
b ackground: animal models with various combination of host-parasite have long been employed to study malaria pathogenesis. here, we describe the combination of plasmodium berghei anka infec- tion in inbred icr mice as a model of cerebral malaria (cm). m ethods: infection in mice was initiated by intraperitoneal injection of 2 x 107 (0.2ml) parasitized red blood cells (prbcs). r esults: this m...
Idiopathic condylar resorption (ICR) is a condition with no known cause, which manifests as progressive malocclusion, esthetic changes, and often pain. Cone-beam computed tomography and magnetic resonance imaging are the most valuable imaging methods for diagnosis and tracking, compared to the less complete and more distorted images provided by panoramic radiographs, and the higher radiation of...
Introduction: Breast cancer (BC) is the most common women cancer worldwide. Radiotherapy and chemotherapy are the two common treatment options but these techniques suffer low selectivity and adverse effects on surrounding normal tissues. Non- ionizing pulsed electromagnetic fields (PEMFs) in ultra-narrow band frequency and intensity have shown anticancer effects. Changing potas...
