Anti-Graying Effects of External and Internal Treatments with Luteolin on Hair in Model Mice.

Little is known about the anti-graying effects of antioxidants on hair. The anti-graying effects of three antioxidants (luteolin, hesperetin, and diosmetin) on hair were investigated according to the sequential processes of hair graying that were previously clarified in model mice [Ednrb(+/-);RET-mice]. External treatment with luteolin, but not that with hesperetin or diosmetin, alleviated hair graying in Ednrb(+/-);RET-mice.

In Vivo Animal Spices and Experimental Technique to Evaluate Sustained Release Granules.

Establishment of a suitable animal model to evaluate sustained release (SR) formulations is very important because it reduces the development time of SR formulations. Beagle dogs are often used to evaluate prototype formulations since they can be directly administered powder, such as drug substance. However, the physiological condition of dogs is very different to that of humans.

Effectiveness of tacrolimus therapy in refractory ulcerative colitis compared to infliximab with propensity score matching.

There is insufficient evidence comparing the outcomes of tacrolimus-based remission induction therapy with infliximab in refractory ulcerative colitis (UC) and evidence regarding optimal strategies after tacrolimus-based remission induction therapy. We conducted a multi-institutional retrospective study of patients with UC treated with tacrolimus or infliximab between January 2010 and March 2019. The proportion of clinical remission at week 8 and cumulative colectomy-free rate were examined using propensity score matching analysis.

This study intended to evaluate the antiplatelet effects of a combined extract of sappan wood ( L.

Efficacy of Molding Helmet Therapy following Suturectomy for Craniosynostosis: A Single-center, Retrospective Analysis in Japan.

Craniosynostosis limits normal cranial growth, significantly affecting the growth and development of children. This increase in intracranial pressure results in significant cosmetic and functional losses. This study investigated the efficacy of combining molding helmets with suturectomy for craniosynostosis.

Identification of Tumor-Suppressive Controlled Genes: as a Therapeutic Target in Breast Cancer.

Our recently created RNA-sequence-based microRNA (miRNA) expression signature in breast cancer clinical specimens revealed that some family members were significantly downregulated in cancer tissues. Based on TCGA database analyses, we observed that among the family members, (the passenger strand derived from pre-) was significantly downregulated in breast cancer (BC) clinical specimens, and its low expression predicted worse prognoses. Ectopic expression assays showed that transfected cancer cells (MDA-MB-157 and MDA-MB-231) had their aggressive phenotypes significantly suppressed, e.

A practical, biomimetic, one-pot synthesis of firefly luciferin.

The bioluminescence reaction of firefly luciferase with D-luciferin has become an indispensable imaging technique in modern biology and life science experiments, but the high cost of D-luciferin is limiting its further application. Here, we report a practical, one-pot synthesis of D-luciferin from p-benzoquinone (p-BQ), L-cysteine methyl ester and D-cysteine, with an overall yield of 46%. Our route, which is six steps in length and proceeds via 2-cyano-6-hydroxybenzothiazole, is inspired by the mechanistic study of our previously reported biomimetic, non-enzymatic, one-pot formation of L-luciferin from p-BQ and L-cysteine.
