Abstract
The areas of the Mount Aso grasslands in Kumamoto, Japan, are the primary location for the breeding of the Kumamoto strain of Japanese Brown cattle (JBRK). Although Aso limonite, deposited by volcanic ash and magma, has been commonly fed to pregnant JBRK in this area, the mechanisms of its salutary effects on pregnant JBRK have not yet been elucidated. Approximately 100 days before the expected day of calf delivery, seven JBRK (four supplemented with limonite and three controls without limonite) were assigned to this study, from which a buccal swab was collected at the highest rumination every 30 days for 90 days. DNA extracted from these swabs was then analyzed using a 16S rRNA gene amplicon sequence analysis. Statistically significant differences between the two groups were discovered through beta-diversity analysis, though results from alpha-diversity analysis were inconclusive. The microbiota identified were classified into six clusters, and three of the main clusters were core-rumen bacteria, primarily cellulose digestion in cluster 1, oral bacteria in cluster 2, and non-core-rumen bacteria in cluster 3. In the limonite group, core-rumen bacteria decreased while non-core-rumen bacteria increased, suggesting that limonite feeding alters rumen microbiota, particularly activation of non-core-rumen microbiota.

A Combination of Natural Products, BenPros (Green Tea Extract, Soybean Extract and Camellia Japonica Oil), Ameliorates Benign Prostatic Hyperplasia. APPLIED SCIENCES-BASEL 2022.

Abstract
Benign prostatic hyperplasia (BPH) is one of the most common diseases in elderly men and causes lower urinary tract symptoms due to excessive proliferation of prostate stromal and epithelial cells. The present study investigated the improving effect of BenPros, an edible natural product mixture (green tea extract, soybean extract and camellia japonica oil), against the development of BPH in vitro and in vivo. BenPros treatment showed inhibitory ability on testosterone-induced androgen receptor, prostate-specific antigen (PSA), and 5α-reductase protein expression in LNCap-LN3 cells and anti-inflammatory effects on LPS-induced increases in interleukin-6 and tumor necrosis factor-α in RAW264.7 cells. In a testosterone propionate (TP)-induced BPH rat model, BenPros decreased the up-regulated serum 5α-dihydrotestosterone and PSA levels. Moreover, BenPros also significantly reduced PSA protein expression in prostate tissue. Furthermore, TP-induced increased expression of cyclooxygenase 2 and B-cell lymphoma 2 (Bcl-2) were reduced by BenPros, resulting in an increase in the Bcl-2/BCL2-related X ratio. These regulatory abilities of BenPros on BPH inducing markers also reduced prostate size and epithelial thickness based on histological analysis. These results indicate that BenPros has a protective ability against BPH in vitro and in vivo, and it may be a promising candidate as a functional food in regulating BPH.
