Thiamine dilauryl sulphate (TDS) exerts a bacteriostatic effect against Gram-positive bacteria and is used as a food additive. The heartwood extract of the Indian kino tree (Pterocarpus marsupium), a medicinal tree native to India, shows weak antimicrobial effects against bacteria and superficial dermatophyte-infective fungi. Herein, we report that the combination of TDS and P.

However, during these fermentations, yeasts are subjected to various environmental stresses, such as ethanol stress, which hinder cell growth and ethanol production. Genetic manipulations and the addition of natural ingredients rich in antioxidants to the culture have been shown to overcome this.

Mixed tumor of the skin (MTS) is a tumor characterized by folliculosebaceous-apocrine differentiation. Because of the wide range of histological variations, understanding the unique features of MTS can help improve diagnosis. This study describes the histopathological characteristics of MTS, mainly apocrine-type MTS (AMT), using 166 cases of AMT.

Dehydrozingerone-a phenolic compound isolated from the rhizome of Zingiber officinale-inhibits drug efflux in Saccharomyces cerevisiae by overexpression of the ATP-binding cassette (ABC) transporter Pdr5p. We aimed to investigate whether dehydrozingerone enhances the antifungal activity of glabridin-an isoflavan isolated from the roots of Glycyrrhiza glabra L.

trans-Anethole (anethole) is a phenylpropanoid; with other drugs, it exhibits synergistic activity against several fungi and is expected to be used in new therapies that cause fewer patient side effects. However, the detailed substructure(s) of the molecule responsible for this synergy has not been fully elucidated. We investigated the structure-activity relationships of phenylpropanoids and related derivatives, with particular attention on the methoxy group and the double bond of the propenyl group in anethole, as well as the length of the p-alkyl chain in p-alkylanisoles.

In KA, four histological stages are recognized, which are the early/proliferative stage, well-developed stage, regressing stage and regressed stage. In diagnosing KA, we emphasize that KA consists of the proliferation of enlarged pale pink cells with ground glass-like cytoplasm without nuclear atypia, other than crateriform architecture.

However, typical skin eruptions, such as evanescent, salmon-pink erythema, are not specific to AOSD and dermatologists often face difficulty in diagnosing AOSD. In this study, we examined serum IL-18 levels as well as IL-6, ferritin and C-reactive protein in 6 Japanese patients with AOSD.

Anethole, the principal component of anise oil, enhances the antifungal activity of nagilactone E. We aimed to determine the combinatorial effect and underlying mechanisms of action of nagilactone E and anethole against the budding yeast .

In the present study, we show that the fungicidal activity of AmB was enhanced by benzyl isothiocyanate (BITC), a cruciferous plant-derived compound, in the budding yeast, Saccharomyces cerevisiae. In addition to forming a molecular complex with ergosterol present in fungal cell membranes to form K -permeable ion channels, AmB has been recognized to mediate vacuolar membrane disruption resulting in lethal effects.

Ultrasonography showed a multilocular mass with a hypoechoic center surrounded by an isoechoic rim. Histopathological analysis revealed that the lesion was composed of small, round cells that were tightly packed and uniform.

Among patients who develop anaphylaxis during anesthesia, anaphylaxis caused by a neuromuscular blocking agent has the highest incidence. In patients who developed IgE-mediated anaphylaxis, and cross-reactivity among NMBAs is a concern in subsequent anesthetic procedures. We present a patient who developed rocuronium-induced anaphylaxis in whom the skin prick test (SPT) and intradermal test (IDT) could identify a safe drug to use in the subsequent anesthetic procedure.

The antifungal activity of n-dodecanol disappears as incubation time passes. In Saccharomyces cerevisiae, anethole, a principal component of anise oil, prolongs the transient antifungal effect of dodecanol by downregulating genes of multidrug efflux pumps, mainly PDR5.

Commonly, methyl-, ethyl-, propyl- and butylparaben are used independently or in combination to maintain the quality of industrial products, and they are considered to have low toxicity. However, recent evidence has suggested that parabens are toxic in mammalian cells, and parabens have been associated with allergic-contact dermatitis, breast cancer and changes in testosterone levels.

DGL lethality was thus examined against Saccharomyces cerevisiae as a model of a yeast that causes food spoilage. In spite of its molecular structure as a nonionic surfactant, DGL could exhibit lethality at a concentration lower than that which caused disruptive damage to the yeast plasma membrane.

Here, a fluorescent PMB derivative (PMB-Ds) was applied to visually confirm the vacuole as a direct lethal target of PMB against fungal cells, which lack LPS. PMB-Ds could be visualized in the normal rounded vacuolar membrane of Saccharomyces cerevisiae cells, suggesting the presence of a molecular ligand assisting the vacuole-targeting mobilization of the peptide in the organism.
