Enhancement of Saltiness Perception by Monosodium Glutamate Taste and Soy Sauce Odor: A Near-Infrared Spectroscopy Study.

Previous studies have reported that the umami taste of monosodium l-glutamate (MSG) and salty-smelling odors (e.g., soy sauce, bacon, sardines) enhance the perception of saltiness.

The effect of chemical and/or mechanical conditioning on the Er:YAG laser-treated root cementum: analysis of surface morphology and periodontal ligament fibroblast attachment.

Background And Objectives: This study compared the surface morphology as well as the biocompatibility of dental root cementum treated with Er:YAG laser irradiation alone and with the laser irradiation followed by chemical and/or mechanical conditioning.

Study Design/materials And Methods: Healthy cementum plates were randomly assigned to the following control and treatment groups: (1) untreated control (C), (2) Er:YAG laser irradiation (L), (3) laser plus tetracycline HCl (TC) placement (L+TP), (4) laser plus TC burnishing (L+TB), (5) laser plus EDTA gel placement (L+EP), (6) laser plus EDTA gel burnishing (L+EB), (7) laser plus saline solution burnishing (L+SB), and (8) laser plus minocycline-HCl paste placement (L+MP). Specimens were subjected to scanning electron microscopy (SEM), histological observation and attachment assay using periodontal ligament (PDL) fibroblasts.

Lack of formation of aldehyde oxidase dimer possibly due to 377G>A nucleotide substitution.

In addition to the many articles reporting on the marked differences in species and large differences in rat strains in response to aldehyde oxidase (AO), individual differences in some rat strains have also been reported. However, little has been clarified about any related molecular biological mechanisms. We previously revealed that nucleotide substitutions of 377G>A and 2604C>T in the AO gene might be responsible for individual differences in AO activity in Donryu strain rats.

Hematologic findings associated with thrombocytopenia during the acute phase of exanthem subitum confirmed by primary human herpesvirus-6 infection.

Purpose: To elucidate the mechanism underlying thrombocytopenia during the acute phase of exanthem subitum (ES), the associated hematological findings were investigated.

Patients And Methods: Five infants with thrombocytopenia during the acute phase of ES serologically confirmed by primary human herpesvirus-6 (HHV-6) were examined and followed-up.

Results: Thrombocytopenia was accompanied by neutropenia, leukopenia, and decreased reticulocyte fraction during the acute phase.
