Growth patterns of facial muscles at the angle of the mouth: A histological study using midterm and near-term human fetuses.

At the angle of the mouth, spoke-like muscle bundles converge at the "modiolus," which is believed to appear in utero. The aim of this study was to investigate the growth of the modiolus histologically. We studied frontal histological sections of the face from 12 midterm and six near-term fetuses.

-Aryl Indoles as a Novel Class of Potent Na1.7 Inhibitors.

A novel class of potent Na1.7 inhibitors has been discovered. The replacement of diaryl ether in compound was investigated to enhance mouse Na1.

Discovery of DS-1971a, a Potent, Selective Na1.7 Inhibitor.

A highly potent, selective Na1.7 inhibitor, DS-1971a, has been discovered. Exploration of the left-hand phenyl ring of sulfonamide derivatives ( and ) led to the discovery of novel series of cycloalkane derivatives with high Na1.

Effects of Fragrance Ingredients on the Uptake of Legionella pneumophila into Acanthamoeba castellanii.

Acanthamoeba castellanii, a ubiquitous organism in water environments, is pathogenic toward humans and also is a host for bacteria of the genus Legionella, a causative agent of legionellosis. Fragrance ingredients were investigated for their antibacterial activity against planktonic Legionella pneumophila, amoebicidal activity against A. castellanii, and inhibitory effect against L.

ER stress response induced by the production of human IL-7 in rice endosperm cells.

Rice seed has been used as a production platform for high value recombinant proteins. When mature human interleukin 7 (hIL-7) was expressed as a secretory protein in rice endosperm by ligating the N terminal glutelin signal peptide and the C terminal KDEL endoplasmic reticulum (ER) retention signal to the hIL-7 cytokine to improve production yield, this protein accumulated at levels visible by Coomassie Brilliant Blue staining. However, the production of this protein led not only to a severe reduction of endogenous seed storage proteins but also to a deterioration in grain quality.

RS-1748, a novel CC chemokine receptor 4 antagonist, inhibits ovalbumin-induced airway inflammation in guinea pigs.

CC chemokine receptor 4 (CCR4) is generally recognized as a preferential marker for T helper 2 cells, and we have previously reported morpholine-derivative CCR4 antagonists, RS-1154 and RS-1269. Here, we investigate the pharmacological profiles of a novel pyrimidine-derivative CCR4 antagonist, 2-{4-[2-(diethylamino)ethoxy]phenyl}-N-(2,4-difluorobenzyl)-5-fluoropyrimidin-4-amine (RS-1748), which showed potency to inhibit the bindings of [(125)I]CCL17 and [(35)S]GTPgammaS to human CCR4-expressing Chinese hamster ovary (CHO) cells with IC(50) values of 59.9 nM and 18.

Development of coenzyme Q10-enriched rice using sugary and shrunken mutants.

Coenzyme Q10 (CoQ10) is a popular food supplement. Earlier, we successfully produced CoQ10 in rice, which normally produces predominately CoQ9. Here we developed efficient production of CoQ10 in rice by introducing the gene for decaprenyl diphosphate synthase into rice sugary and shrunken mutants.

Novel triple neurokinin receptor antagonist CS-003 inhibits respiratory disease models in guinea pigs.

Neurokinins are known to induce neurogenic inflammation related to respiratory diseases. The effects of CS-003 ([1-{2-[(2R)-(3,4-dichlorophenyl)-4-(3,4,5-trimethoxybenzoyl)morpholin-2-yl]ethyl}spiro[benzo[c]thiophene-1(3H),4'-piperidine]-(2S)-oxide hydrochloride]), a novel triple neurokinin receptor antagonist, on several respiratory disease models were evaluated in guinea pigs. As we have already shown that CS-003 is intravenously effective, we first determined if CS-003 was orally effective.

Novel triple neurokinin receptor antagonist CS-003 strongly inhibits neurokinin related responses.

Neurokinins are known to induce neurogenic inflammation related to respiratory diseases, though there is little information on triple neurokinin receptor antagonists. The pharmacological properties of the novel triple neurokinin 1, 2 and 3 receptor antagonist [1-(2-[(2R)-(3,4-dichlorophenyl)-4-(3,4,5-trimethoxybenzoyl)morpholin-2-yl]ethyl)spiro[benzo[c]thiophene-1(3H),4'-piperidine]-(2S)-oxide hydrochloride] (CS-003) were evaluated in this study. The binding affinities of CS-003 were evaluated with human and guinea pig neurokinin receptors.

Metabolic engineering of coenzyme Q by modification of isoprenoid side chain in plant.

Coenzyme Q (CoQ), an electron transfer molecule in the respiratory chain and a lipid-soluble antioxidant, is present in almost all organisms. Most cereal crops produce CoQ9, which has nine isoprene units. CoQ10, with 10 isoprene units, is a very popular food supplement.

Complete nucleotide sequence of the sugarcane (Saccharum officinarum) chloroplast genome: a comparative analysis of four monocot chloroplast genomes.

The complete nucleotide sequence of the chloroplast genome of sugarcane (Saccharum officinarum) has been determined. It is a circular double-stranded DNA molecule, 141,182 bp in size, and is composed of a large single copy of 83,048 bp, a small single copy of 12,544 bp, and a pair of inverted repeat regions of 22,795 bp each. A comparative analysis among monocots showed that the sugarcane chloroplast genome was very similar to maize but not to rice or wheat.

Involvement of enhanced neurokinin NK3 receptor expression in the severe asthma guinea pig model.

In this study, we investigated the involvement of neurokinin NK3 receptors in a severe asthma model prepared by administering ovalbumin via inhalation three times to systemically sensitized guinea pigs. [3H]senktide, a neurokinin NK3 receptor ligand, showed significant specific binding to the lungs from the model animals, but not to those from negative control animals. The airway responsiveness to intravenous neurokinin B, a neurokinin NK3 receptor agonist, was increased in the model, indicating an increase in functional NK3 receptors.

Greater involvement of neurokinins found in Guinea pig models of severe asthma compared with mild asthma.

Background: Involvement of neurokinins in asthma has been previously pointed out by several reports. However, the relationship between neurokinins and the severity of asthma has remained unclear. We developed a model of mild asthma (model I) and severe asthma (model II) in guinea pigs, and investigated the function of neurokinins in both models.
