Lecithin-Based Dermal Drug Delivery for Anti-Pigmentation Maize Ceramide.

Ceramides have several well-known biological properties, including anti-pigmentation and anti-melanogenesis, which make them applicable for use in skincare products in cosmetics. However, the efficacy of ceramides is still limited. Dermal or transdermal drug delivery systems can enhance the anti-pigmentation properties of ceramides, although there is currently no systemic evaluation method for the efficacy of these systems.

Allelic Mutations in the Locus Generate Extensive Variation in Tomato Ripening.

RIPENING INHIBITOR (RIN) is a transcription factor with transcriptional activator activity that plays a major role in regulating fruit ripening in tomato (). Recent studies have revealed that (1) is indispensable for full ripening but not for the induction of ripening; and (2) the mutation, which produces nonripening fruits that never turn red or soften, is not a null mutation but instead converts the encoded transcriptional activator into a repressor. Here, we have uncovered aspects of function by characterizing a series of allelic mutations within this locus that were produced by CRISPR/Cas9.

Water Extract of Yamato Tachibana () Induces Food Intake in Adult and Larval Zebrafish.

Yamato Tachibana (Tachibana; ) is an endemic fruit and represents one of the oldest citrus species in Japan; it is grown in the Mie Prefecture. It has been attracting attention for its cultural heritage and unique scent. To evaluate biological activities of Tachibana, we fed several parts of the Tachibana fruit (whole fruit, pulp [albedo and segment wall], and flavedo) to adult zebrafish and found that Tachibana increased body weight and plasma triglycerides besides increasing overall food intake.

Aging-associated microstructural deterioration of vertebra in zebrafish.

Zebrafish, a small teleost fish, is currently emerging as an animal model of local and systemic aging. In this study, we assessed age-related degenerative changes in the vertebral bone of zebrafish (3-12 month-post-fertilisation [mpf]) using micro-CT scanning. The bone volume (BV) of the trabecular bone in the male and female fish peaked at 6 mpf and reduced with age.

An Integrative Evaluation Method for the Biological Safety of Down and Feather Materials.

Background: Down and feather materials have been commonly used and promoted as natural stuffing for warm clothing and bedding. These materials tend to become more allergenic as they become contaminated with microorganisms, in addition to being subjected to several kinds of chemical treatments. The biological or chemical contaminants in these materials pose a major risk to human health, to consumers and manufacturers alike.

ZF-Mapper: Simple and Complete Freeware for Fluorescence Quantification in Zebrafish Images.

Zebrafish embryos and larvae have become popular vertebrate models because their body walls are transparent, which enables live imaging of target organs using fluorescent protein transgenes or dye staining. Software packages for the quantification of these fluorescent signals are available from both commercial and noncommercial sources; however, their algorithms are complicated and their resources (code) have mostly not been openly shared. In this study, we developed a simple and robust open-source software tool named "ZF-Mapper" for the quantification of the fluorescence intensity of each pixel in zebrafish images with batch image file processing capability.

Microbiome Alteration in Type 2 Diabetes Mellitus Model of Zebrafish.

Understanding the gut microbiota in metabolic disorders, including type 2 diabetes mellitus (T2DM), is now gaining importance due to its potential role in disease risk and progression. We previously established a zebrafish model of T2DM, which shows glucose intolerance with insulin resistance and responds to anti-diabetic drugs. In this study, we analysed the gut microbiota of T2DM zebrafish by deep sequencing the 16S rRNA V3-V4 hypervariable regions, and imputed a functional profile using predictive metagenomic tools.
