Plants possess active defense systems and can protect themselves from pathogenic invasion by secretion of a variety of small antimicrobial or antifungal proteins such as thionins. The antibacterial and antifungal properties of thionins are derived from their ability to induce open pore formation on cell membranes of phytopathogens, resulting in release of(More)
nature medicine volume 17 | number 1 | january 2011 29 addition, they showed in a retrospective clinical study that thrombocytopenia increases the risk for PDA in German premature newborns2. To test whether thrombocytopenia generally increases the risk for PDA, we investigated the association between PDA and thrombocytopenia in Japanese premature newborns(More)
We investigated the nitric oxide profile in the plasma of ten healthy controls and 29 patients hurt by the Kobe Earthquake. The levels of nitrite (NO2-) and nitrate (NO3-) were measured simultaneously by high-performance liquid chromatography (HPLC) with UV detection using the Griess reaction after the reduction of nitrate to nitrite. Arginine consumed in(More)
BACKGROUND The American Academy of Pediatrics guidelines recommend that the total bilirubin (TB)/albumin (Alb) ratio (B/A ratio), instead of serum concentration of unbound bilirubin (UB), can be used with TB for determining treatment modality for jaundiced newborns ≥ 35 weeks of gestation. It is unknown, however, whether the B/A ratio is actually correlated(More)
BACKGROUND Free bilirubin concentration (B(f)) is an index for identifying newborns at risk for developing bilirubin-induced neurotoxicity. It has been suggested that B(f) measured by a single peroxidase concentration (B(f-single)) does not equal the equilibrium concentration of B(f), which is confirmed by B(f) at two different peroxidase concentrations(More)
BACKGROUND Menkes disease is a lethal disorder associated with copper metabolism. Although early treatment with copper-histidine injections can improve outcomes, early diagnosis is difficult because the clinical features of Menkes disease are subtle or do not manifest in affected neonates. Previous report stated that the low activity of dopamine(More)
BACKGROUND Recent Japanese epidemiology of neonatal sepsis and its predominant pathogens has not been reported. It is also unknown whether there are center differences in the incidence of neonatal sepsis, including early-onset sepsis (EOS) and late-onset sepsis (LOS) in Japan. OBJECTIVES To investigate the morbidity and characteristics of neonatal sepsis(More)
While the automatic music transcription has been researched recently, i t i s difficult to make a melody score in case of many instructions because i t is difficult to separate a music source from many music souwes. In this paper, we describe the method of automatic music transcription for a trio using stereo musical sound signal. We estimate where the(More)
BACKGROUND Autosomal dominant pseudohypoaldosteronism type 1 (PHA1) is a rare inherited condition that is characterized by renal resistance to aldosterone as well as salt wasting, hyperkalemia, and metabolic acidosis. Renal PHA1 is caused by mutations of the human mineralcorticoid receptor gene (MR), but it is a matter of debate whether MR mutations cause(More)
