Serine/arginine-rich proteins (SR proteins) constitute a family of RNA-binding proteins conserved throughout metazoans. The SR proteins are essential for constitutive pre-mRNA splicing and also affect regulated pre-mRNA splicing. We identified five putative genes encoding SR proteins (referred to as srp genes) in Caenorhabditis elegans, examined their(More)
In response to high population density or low food supply, the nematode Caenorhabditis elegans enters an alternative larval stage, known as the dauer, that can withstand adverse conditions for prolonged periods. C. elegans senses its population density through a small-molecule signal, traditionally called the dauer pheromone, that it secretes into its(More)
BACKGROUND Previous work has shown that all-trans-retinoic acid reverses elastase induced emphysema in rats. Since there is currently no effective treatment for pulmonary emphysema, the effect of retinoic acid should be further investigated in other adult species. A study was undertaken using two murine models of emphysema to evaluate the effect of retinoic(More)
Tumor necrosis factor-alpha (TNF-alpha) transgenic mice have previously been found to have characteristics consistent with emphysema and severe pulmonary hypertension. Lungs demonstrated alveolar enlargement as well as interstitial thickening due to chronic inflammation and perivascular fibrosis. In the present report, we sought to determine potential(More)
The nationwide surveillance on antimicrobial susceptibility of bacterial respiratory pathogens from patients in Japan, was conducted by Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases and Japanese Society for Clinical Microbiology in 2010. The isolates were collected from clinical specimens obtained from well-diagnosed adult(More)
We identified MRG-1, a Caenorhabditis elegans chromodomain-containing protein that is similar to the human mortality factor-related gene 15 product (MRG15). RNA-mediated interference (RNAi) of mrg-1 resulted in complete absence of the germline in both hermaphrodite and male adults. Examination of the expression of PGL-1, a component of P granules, revealed(More)
Development of a symptom specific health status measure for patients with chronic cough: Idiopathic pleuroparenchymal fibroelastosis is a peculiar pulmonary fibrosis proposed by FRANKEL et al. [1] in 2003 and is almost the same concept as idiopathic pulmonary upper lobe fibrosis proposed by AMITANI et al. [2]. There are no known causes for fibrosis in(More)
Sixteen infants were analyzed longitudinally from the onset of independent walking to 3 years of age using time parameters, speed and energy recovery. Considerable variation and irregularities were observed in many parameters of infant walking, especially until 13 months of age when infants had difficulty in walking steadily step by step. Infant walking(More)
Coordination between cell proliferation and differentiation is important in normal development and oncogenesis. These processes usually have an antagonistic relationship, in that differentiation is blocked in proliferative cells, and terminally differentiated cells do not divide. In some instances, cyclins, cyclin-dependent kinases (CDKs) and their(More)
