Agr virulence is critical for epidermal colonization and associates with atopic dermatitis development.

Atopic dermatitis (AD) is commonly associated with colonization by in the affected skin. To understand the role of in the development of AD, we performed whole-genome sequencing of strains isolated from the cheek skin of 268 Japanese infants 1 and 6 months after birth. About 45% of infants were colonized with at 1 month regardless of AD outcome.

Genetic Determinants of Virulence between Two Foot-and-Mouth Disease Virus Isolates Which Caused Outbreaks of Differing Severity.

Individual foot-and-mouth disease virus (FMDV) strains reveal different degrees of infectivity and pathogenicity in host animals. The differences in severity among outbreaks might be ascribable to these differences in infectivity among FMDV strains. To investigate the molecular mechanisms underlying these differences, we estimated the infectivity of O/JPN/2000 and O/JPN/2010, which caused outbreaks of markedly different scales, in cell lines, Holstein cattle, and suckling mice.

Development of an immunochromatographic assay for the rapid detection of AAC(6')-Iae-producing multidrug-resistant Pseudomonas aeruginosa.

Objectives: To develop an easy-to-use method for the rapid detection of antibiotic-resistant bacteria. Here, a new immunochromatographic assay specific for aminoglycoside 6'-N-acetyltransferase AAC(6')-Iae was designed. AAC(6')-Iae is a significant marker molecule for multidrug-resistant (MDR) Pseudomonas aeruginosa isolates in Japan.

Effects of the Ih blockers CsCl and ZD7288 on inherited epilepsy in Mongolian gerbils.

The h current (Ih) is an inwardly mixed cationic conductance activated by membrane hyperpolarization. We previously demonstrated that the Ih blockers CsCl and ZD7288 can significantly increase the threshold of electrically induced paroxysmal discharge in the rabbit hippocampus. In the present study, we examined the effects of these Ih blockers on inherited epilepsy in Mongolian gerbils.

[Two cases of Senior-Loken syndrome].

Background: We report two rare cases of Senior-Loken syndrome, one with fundus lesions simulating Coats disease. CASE 1: A 14-year-old boy had juvenile nephronophthisis and bilateral retinitis pigmentosa with retionochoroidal atrophy and salt and pepper fundus. Electroretinogram (ERG) showed non-recordable changes and the Goldmann perimeter showed ring scotomas.

Ih blockers have a potential of antiepileptic effects.

Purpose: The h current (Ih) is an inwardly mixed cationic conductance activated by membrane hyperpolarization and distributed predominantly in the apical dendrites of hippocampal pyramidal neurons. To verify a hypothesis that an anomalous hyperpolarization generates an abnormal excitation by way of Ih channels, we examined the effects of Ih blockers (CsCl and ZD7288) on electrically induced paroxysmal discharges (PADs).

Methods: Fifty-three adult male rabbits were used.
