Taste Preference and Metabolic Rate of Trehalose in Chickens.

Trehalose (Tre) is composed of two molecules of D-glucose joined by an α,α-1,1 glucosidic linkage. Because Tre is utilized by the gut microbiome and enhances gut immunity in chickens, it is used as a feed ingredient. However, taste preference and metabolic dynamics of Tre in chickens are not fully understood.

A very long chain fatty acid responsive transcription factor, MYB93, regulates lateral root development in Arabidopsis.

Lateral roots (LRs) are critical to root system architecture development in plants. Although the molecular mechanisms by which auxin regulates LR development have been extensively studied, several additional regulatory systems are hypothesized to be involved. Recently, the regulatory role of very long chain fatty acids (VLCFAs) has been shown in LR development.

Pathological social withdrawal in autism spectrum disorder: A case control study of hikikomori in Japan.

(Ritter, 1910) was first recorded from Ceylon (now Sri Lanka) and has also been known from Central American countries including Guyana and Cuba. Recently, its rapid spread to European countries, including Austria, Czech, Germany and Norway, has been reported.

Streptococcal Infection-related Glomerulonephritis in an Elderly Diabetic Patient Complicated by Hemophagocytic Syndrome and Cytomegalovirus Nephritis.

There has been a significant shift in epidemiology and renal outcomes of infection-related glomerulonephritis (IRGN) in recent years. The renal prognosis of IRGN is often poor in adults, especially in the elderly and diabetics. We herein report an elderly diabetic patient with IRGN due to streptococcal infection complicated by hemophagocytic syndrome and cytomegalovirus nephritis, which is uncommon among non-transplant patients.

Successful management of severe asthma in a young boy with eosinophilic chronic rhinosinusitis who received omalizumab: a case report.

Background: The incidence of chronic rhinosinusitis with nasal polyps has recently increased in Japan and other East Asian countries, and this disease is called eosinophilic chronic sinusitis (ECRS) in Japan. ECRS usually occurs in adults and is frequently accompanied by refractory bronchial asthma. However, its occurrence in children under 10 years of age is rare.

Synergism between α-mangostin and TRAIL induces apoptosis in squamous cell carcinoma of the oral cavity through the mitochondrial pathway.

Mangosteen (Garcinia mangostana) is a tree found in South-East Asia and the pericarp of its fruit has been used in folk medicine for the treatment of many human illnesses. Mangosteen fruit rinds contain a high concentration of xanthone, which is a type of polyphenol. One type of xanthone, α-mangostin, has been reported to exert chemopreventive effects against chemically-induced colon cancer through the decrease of c-Myc expression, suppressing tumor growth in a mouse model of mammary cancer.

Maternal Exposure to Pyrethroid Insecticides during Pregnancy and Infant Development at 18 Months of Age.

The possible association between maternal exposure to pyrethroid insecticides (PYRs) during pregnancy and infant development was explored. Levels of exposure to PYRs was assessed by metabolite (3-phenoybenzoic acid, 3-PBA) concentration in maternal spot urine sampled in the first trimester of index pregnancy, and infant development was assessed at 18 months of age using the Kinder Infants Development Scale (KIDS), which is based on a questionnaire to the caretaker. The relationship between KIDS score and maternal urinary 3-PBA levels was examined by a stepwise multiple regression analysis using biological attributes of the mother and infant, breast feeding, and nursing environment as covariates.

Fast response to human voices in autism.

Individuals with autism spectrum disorders (ASD) are reported to allocate less spontaneous attention to voices. Here, we investigated how vocal sounds are processed in ASD adults, when those sounds are attended. Participants were asked to react as fast as possible to target stimuli (either voices or strings) while ignoring distracting stimuli.

Background: Previous studies have shown activity against viruses, bacteria, inflammation and oral lichenoid dysplasia of alkaline extract of the leaves of Sasa senanensis Rehder (SE), suggesting its possible application to oral diseases. In the present study, we performed a small-scale clinical test to investigate whether SE is effective against halitosis and in oral bacterial reduction.

Materials And Methods: A total of 12 volunteers participated in this study.

Vocal Identity Recognition in Autism Spectrum Disorder.

Voices can convey information about a speaker. When forming an abstract representation of a speaker, it is important to extract relevant features from acoustic signals that are invariant to the modulation of these signals. This study investigated the way in which individuals with autism spectrum disorder (ASD) recognize and memorize vocal identity.

Enhanced segregation of concurrent sounds with similar spectral uncertainties in individuals with autism spectrum disorder.

When acoustic signals from different sound sources are mixed upon arrival at the ears, the auditory system organizes these acoustic elements by their features. This study shows that individuals with autism spectrum disorder (ASD) performed better in terms of hearing a target sequence among distractors that had similar spectral uncertainties. Their superior performance in this task indicates an enhanced discrimination between auditory streams with the same spectral uncertainties but different spectro-temporal details.

Prenatal pyrethroid insecticide exposure and thyroid hormone levels and birth sizes of neonates.

Pyrethroid insecticides have been shown to possess thyroid hormone disrupting properties in previous animal studies. In this study, the relationship between maternal exposure to pyrethroid insecticides during pregnancy and neonatal thyroid hormone status (free thyroxine (fT4) and thyroid stimulating hormone (TSH) in whole blood) and birth sizes were explored in 147 mother-neonate pairs in Tokyo. The concentration of 3-phenoxybenzoic acid (3-PBA) in maternal urine, sampled in the first trimester of gestation, was used for pyrethroid exposure assessment.

Associations between levels of hydroxylated PCBs and PCBs in serum of pregnant women and blood thyroid hormone levels and body size of neonates.

The purpose of this study was to investigate possible associations between concentrations of hydroxylated PCBs (OH-PCBs) and PCBs in the serum of women in the first trimester of pregnancy and thyroid hormone levels and body size of newborn infants in 79 mother-neonate pairs. We measured 16 OH-PCB isomers and 29 PCB isomers in the serum of Japanese women sampled at 11.1±1.

Behavioral abnormalities observed in Zfhx2-deficient mice.

Zfhx2 (also known as zfh-5) encodes a transcription factor containing three homeobox domains and 18 Zn-finger motifs. We have reported that Zfhx2 mRNA is expressed mainly in differentiating neurons in the mouse brain and its expression level is negatively regulated by the antisense transcripts of Zfhx2. Although the expression profile of Zfhx2 suggests that ZFHX2 might have a role in a particular step of neuronal differentiation, the specific function of the gene has not been determined.

A 3-year-old girl with Graves' disease with hypoglycemia following transient adrenal hyporesponsiveness.

A 3-year-old girl with Graves' disease developed a generalized convulsion as a result of hypoglycemia (25 mg/dL). At the time of the hypoglycemic seizure, her plasma adrenocorticotropin (ACTH) level (1460 pg/mL) was extremely high, but her serum cortisol level (28.4 microg/dL) was relatively low given the severe stress.

Rhodium-catalyzed complete regioselective intermolecular cross-cyclotrimerization of aryl ethynyl ethers and nitriles or isocyanates at room temperature.

We have established that a cationic rhodium(I)/H(8)-BINAP complex catalyzes the complete regioselective intermolecular cross-cyclotrimerization of aryl ethynyl ethers and nitriles or isocyanates leading to 2,4-diaryloxypyridines or 4,6-diaryloxy-2-pyridones at room temperature.

Flexible synthesis of fused benzofuran derivatives by rhodium-catalyzed [2 + 2 + 2] cycloaddition with phenol-linked 1,6-diynes.

A flexible and convenient synthesis of fused benzofuran derivatives has been achieved under mild reaction conditions by cationic rhodium(I)/H(8)-BINAP complex-catalyzed [2 + 2 + 2] cycloadditions of phenol-linked 1,6-diynes with alkynes and nitriles.

Integration of chloroplast nucleic acid metabolism into the phosphate deprivation response in Chlamydomonas reinhardtii.

Cell survival depends on the cell's ability to acclimate to phosphorus (P) limitation. We studied the chloroplast ribonuclease polynucleotide phosphorylase (PNPase), which consumes and generates phosphate, by comparing wild-type Chlamydomonas reinhardtii cells with strains with reduced PNPase expression. In the wild type, chloroplast RNA (cpRNA) accumulates under P limitation, correlating with reduced PNPase expression.

Cleaved inflammatory lactoferrin peptides in parotid saliva of periodontitis patients.

Lactoferrin (Lf) is a member of the transferrin family of iron-binding anti-bacterial proteins, present in most exocrine secretions, such as saliva, and plays an important role in mucosal defense. In this study, we identified small Lf peptides with Con A low-affinity in the parotid saliva of chronic periodontitis patients by Con A two-dimensional immunoelectrophoresis, Con A affinity chromatography and Western blotting using anti-human Lf polyclonal Ab. N-terminal amino acid sequencing of the four Con A low-affinity Lf peptides confirmed them to be fragments of intact Lf.

Inflammatory effect of cleaved bovine lactoferrin by elastase on staphylococcal mastitis.

Elastase activity and concanavalin A (Con A) low affinity bovine lactoferrin (bLf) molecule were detected in mammary gland secretions (MGSs) from mammary glands (MGs) with clinical staphylococcal mastitis. Changes in clinical symptoms correlated with increases in both elastase activity and the concentration of Con A low-affinity Lf in MGSs from mastitic MGs. Bovine Lf treated with elastase (elastase-Lf) showed various small bLf molecules and the same image on Con A two-dimensional immunoelectrophoresis as low Con A affinity bLf in MGSs.

Differential regulation of intestinal lipid metabolism-related genes in obesity-resistant A/J vs. obesity-prone C57BL/6J mice.

The effects of high-fat (HF) feeding on gene expression in the small intestine were examined using obesity-resistant A/J mice and obesity-prone C57BL/6J (B6) mice. Both strains of mice were maintained on low-fat (LF; 5% fat) or HF (30% fat) diets for 2 wk. Quantitative reverse transcription-PCR analysis revealed that lipid metabolism-related genes, including carnitine palmitoyltransferase (CPT) I, liver fatty acid binding protein, pyruvate dehydrogenase kinase-4, and NADP(+)-dependent cytosolic malic enzyme, were upregulated by HF feeding in both strains of mice.

Effect of combination therapy with lactoferrin and antibiotics against staphylococcal mastitis on drying cows.

We examined combination therapy with both lactoferrin (Lf) and antibiotics on clinical mastitis due to Staphylococcus aureus (S.aureus) on drying cows. The clinical symptoms of mastitic quarters were cured 81% of combination therapeutic quarters at 7 days post injection (dpi).
