Report on the mutagenicity of flavone derivatives and their contribution to advancing scientific knowledge

open access: yesProceedings of the Japan Academy. Series B, Physical and Biological Sciences
Flavonoids, such as quercetin and kaempferol, and their glycosides, are widely distributed in vegetables and fruits. Sugimura, T. et al. investigated the mutagenicity of flavone derivatives, and found that quercetin and kaempferol showed high mutagenic ...

Natural Sweetener Stevioside‐Based Dissolving Microneedles Solubilize Minoxidil for the Treatment of Androgenic Alopecia

open access: yesAdvanced Healthcare Materials, EarlyView.
This study addresses limitations of minoxidil (MXD) in treating androgenetic alopecia by using stevioside (STV) as a solubilizing agent and microneedle (MN) material. STV enhanced MXD's solubility and skin absorption, leading to improved drug delivery and significant hair regrowth in animal models, demonstrating strong potential for AGA treatment ...

Characterization of Microplastics in Human Gastric Cancer and Control Tissues and Analysis of Associated Genetic Features

open access: yesAdvanced Healthcare Materials, EarlyView.
This study characterizes the presence of microplastics in human normal gastric, para‐tumor, and gastric tumor tissue and confirms the association between microplastic exposure and lymph node metastasis in gastric cancer. This study explores the transcriptomic changes induced by microplastic exposure, laying the foundation for further investigation into

Induction of Colonic Aberrant Crypts in Mice by Feeding Apparent N-Nitroso Compounds Derived From Hot Dogs [PDF]

open access: yes, 2012
Nitrite-preserved meats (e.g., hot dogs) may help cause colon cancer because they contain N-nitroso compounds. We tested whether purified hot-dog-derived total apparent N-nitroso compounds (ANC) could induce colonic aberrant crypts, which are putative ...

Porous Bi2S3 Bulk With Excellent Thermoelectric Performance by Solid States Replacement and Low Melting‐Point Metal Volatilization

open access: yesAdvanced Materials, EarlyView.
By introducing FeCoNi medium‐entropy alloy, the bismuth sulfide (Bi2S3) material achieves a record‐high ZT of 1.1 at 773 K, owing to the solid‐states replacement reaction and the volatilization of low melting‐point metal. This strategy is also applicable to other sulfur‐based thermoelectric materials.

Prediction Of Cancer Possibility By Pattern Recognition And Statistical Study Of Expression Of Gene Level Of Cancer Cells [PDF]

open access: yes, 2011
The activity of the p53 tumor-suppressor protein has a key role in controlling both cancer and aging: under activity encourages the growth of cancer, and over activity can accelerate the aging process.
