Paddy rice is a potential feed grain for chickens, whose strong gizzards can crush the hull. Here, we investigated whether paddy rich in hull-derived water-insoluble dietary fiber stimulates intestinal mucin secretion and production, as well possible involvement of barrier function. Layer male chicks at 7 d age were divided into four groups according to diet: corn, polished rice, brown or (650 g/kg diet), which they ate 14 consecutive days. At 21 age, birds refed their experimental diets,...

Evolution optimizes a living system at both the genome and transcriptome levels. Few studies have investigated evolution, whereas many explored evolution in experimentally evolved cells. However, comprehensive understanding of evolutionary mechanisms requires knowledge how shapes gene expression. Here, we analyzed Escherichia coli strains acquired during long-term thermal adaptive evolution. Evolved ancestor cells were exponentially grown under normal high temperatures for subsequent...

Gatifloxacine (GFLX)-containing poly(lactide-co-glycolide) (PLGA) was introduced to the pores and surfaces of porous β-tricalcium phosphate (βTCP) granules by melt compounding whereby no toxic solvent used. The granular composite GFLX-loaded PLGA βTCP released GFLX for 42 days in Hanks' balanced solution exhibited sufficient vitro bactericidal activity against Streptococcus milleri Bacteroides fragilis at least 21 days. For vivo evaluation, implanted dead space created debridement...

The Japanese domestic production of commercial grade hydrogen peroxide (HP) for chemical industries are more than 300,000 tons/year (reduced 100%) but its concentration was regulated below 60% handing, storages and shipping safety, no rocket (90%) HP have been produced after 1970. However, Kawasaki Heavy Industries Ltd. (KHI) has developing the decomposed products HP/JP-4 liquid engine as clean turbofan driver gas generator ATR engine. Using similar igniter torch solid fuel, it is possible...

Abstract Pulmonary arterial hypertension (PAH) is a fatal disease that often occurs at an early age. In recent years, aggressive treatment with multiple drugs from the early‐stage diagnosis expected to improve prognosis. Indeed, high rate of initial combination therapy and excellent outcomes have been reported specialized centers for PAH in Japan. However, information on epidemiology, including non‐PAH Japan, unclear. To address above, we conducted retrospective observational cohort study...

A series of Escherichia coli strains with varied genomic sequences were subjected to high-density microarray analyses elucidate the fitness-correlated transcriptomes. Fitness, which is commonly evaluated by growth rate during exponential phase, not only determined genome but also linked conditions, e.g., temperature. We previously reported genetic and environmental contributions E. transcriptomes evolutionary transcriptome changes in thermal adaptation. Here, we describe experimental details...

Pulmonary hypertension (PH) is often complicated by chronic lung diseases (CLDs) such as obstructive pulmonary disease (COPD) and interstitial (ILD). Differentiating between PH associated with CLD (group 3 PH) arterial (PAH) in difficult reporting on the efficacy of PAH-specific therapies inconsistent a result lack understanding heterogeneity patients PH. A retrospective observational cohort study was conducted to understand baseline characteristics, comorbidities, treatment profiles...

The 90% hydrogen peroxide (HP), concentrated in lab-scale from Japanese domestic production of commercial grade HP, currently regulated below 60% for storing and handling safety have been applied to single perforation polyethylene solid fuel experimental hybrid rocket. Modified 3-way catalyst utilized decomposing the HP. temperature decomposed products HP attain higher than auto-ignition with almost fuels, though a liquid rocket engine assisting ignition decreasing combustion pressure...

The Air Turbo Ramjet (ATR) is a combined cycle engine which performs like turbojet at subsonic speeds and ramjet supersonic therefore the ATR an attractive propulsion system for wide operation range (e.g. Mach 0 to 4). can provide higher specific impulse than solid fuel rocket thrust per frontal area engine. major components are inlet, fan (compressor), turbine, gas generator, combustor exhaust nozzle. In ATR, turbine drive generated by decomposed liquid or generator. order carry heavier...

As the next generation propulsion system, an Air Turbo Ram (ATR) engine, a combined engine of ramjet and turbojet, is one most promising candidates. This needs to be compact accommodate heavier payloads enable longer distance flight. The ram combustor, its major component, no exception required more shorter in axial length. But defect shortening it combustion efficiency becomes lower. To shorten combustor obtain excellent efficiency, doublestaged flameholder scheme was introduced. A rear...
