OBJECTIVE To determine the pharmacokinetics and safety of RAD001 (everolimus) in Japanese patients with advanced solid tumors. METHODS An open-label, non-randomized, dose-escalation Phase I study of RAD001 administered continuously once daily in a 28-day cycle was performed. The study had a '3 + 3' design, with three patients recruited to each of three(More)
In plants, post-transcriptional RNA silencing (PTGS) signals move beyond their sites of synthesis using channels called plasmodesmata (PD). However, a potential influence of PD permeability in silencing signal movement has not been addressed previously. PD connectivity and aperture are routinely determined by monitoring the cell-to-cell movement of protein(More)

Two of the most potent cytokines that regulate anterior pituitary cell function are leukemia inhibitory factor and IL-6. These and others like IL-11 and ciliary neurotrophic factor are referred to as the gp130 cytokines because they share the gp130 glycoprotein as a common receptor initial signal transducer. We and others have shown that gp130 cytokines and(More)
Mastitis, inflammation of the mammary gland, is the most costly common disease in the dairy industry, and is caused by mammary pathogenic bacteria, including Escherichia coli. The bacteria invade the mammary alveolar lumen and disrupt the blood-milk barrier. In normal mammary gland, alveolar epithelial tight junctions (TJs) contribute the blood-milk barrier(More)
Chenopodium quinoa can grow at altitudes of 3,600–4,000 masl and is adapted to the highly arid conditions typical of the salty soils in the South American Altiplano, with less than 250 mm of annual rain and temperatures below 0°C. The aim of the study was to investigate the effect of salinity on the dehydrin content of mature embryos harvested from(More)
The purpose of this study is to investigate the effect and the circuit from the branch of tibial (plantar) nerve to soleus muscle and its modulation during walking in humans. Stimulation of the plantar nerve produced short latency inhibition of soleus EMG activity and the H-reflex in humans. The threshold of afferent fibers was lower than that of motor(More)
The mammary gland is a highly specialized organ that is able to repeat development and regression (involution) of alveolar structures for milk production. Mammary involution consists in two phases. The first phase is reversible and lasts until approximately 48 h after weaning in mice. Interestingly, an extended milking interval can change the milk-secretory(More)
The mammary alveolus is a highly specialized structure that secretes milk for suckling infants during lactation. The secreting alveolus consists in alveolar epithelial cells (AECs) and myoepithelial cells and is surrounded by microvascular endothelial cells, adipocytes and several immune cell types such as macrophages and neutrophils. During normal(More)
Mastitis, the inflammation of mammary glands resulting from bacterial infection, disrupts milk production in lactating mammary glands. In this study, we injected lipopolysaccharide (LPS), one of the endotoxins from Escherichia coli into mouse mammary glands to disrupt milk production, and we investigated the influence of LPS on nutrient uptake, synthesis,(More)
Various structures have been reported for dermoscopic features of pigmented Bowen's disease (BD), which could be a mimic of various pigmented skin lesions. A 79-year-old Japanese woman presented with a 3-year history of brown-black macule on her right upper arm without symptom. Dermoscopic examination demonstrated irregular flossy streaks, irregular brown(More)
