Development of a Water-Soluble Nanomicellar Formulation Loaded with Trans-Resveratrol Using Polyethylene Glycol Monostearate for the Treatment of Intracerebral Hemorrhage.

Trans-resveratrol (Res) has been reported to possess many biological activities, including neuroprotective effects, owing to its anti-inflammatory and antioxidant properties. However, Res has very low water solubility, which limits its therapeutic application. In this work, we formulated water-soluble micellar formulations incorporating Res using polyethylene glycol monostearate (stPEG).

Carnosic acid inhibits integrin expression and prevents pulmonary metastasis of melanoma.

Carnosic acid is a naturally occurring, plant-derived polyphenolic abietane diterpene with anti-tumor properties. However, its underlying mechanisms are still unclear. Therefore, we investigated the effects of carnosic acid on lung metastasis in a murine melanoma model.

Shimanami Leaf Intake Affects Bowel Movement and Intestinal Microbiota in Mice.

The Shimanami Leaf, produced at Innoshima Island in Onomichi City, Hiroshima Prefecture, Japan, is a leafy vegetable that does not require pesticide use and has a high nutritional value. Although the leaf has abundant dietary fiber and other nutrients, reports on its biological regulatory functions are lacking. Therefore, this study aimed to elucidate the effects of Shimanami leaf intake on bowel movement and gut microbiota in mice.

Senescence-accelerated mice prone 8 (SAMP8) in male as a spontaneous osteoarthritis model.

Background: Animal models of spontaneous osteoarthritis (OA) are sparse and not well characterized. The purpose of the present study is to examine OA-related changes and mechanisms in senescence-accelerated mouse prone 8 (SAMP8) that displays a phenotype of accelerated aging.  METHODS: Knees of male SAMP8 and SAM-resistant 1 (SAMR1) mice as control from 6 to 33 weeks of age were evaluated by histological grading systems for joint tissues (cartilage, meniscus, synovium, and subchondral bone), and µCT analysis.

Anti-stress effects of rosemary ( L.) leaf extract on intestinal goblet cells and immobility of forced-swimming test in BALB/c mice.

We investigated the anti-stress effect of rosemary ( L.) leaf extract (RLE) on restraint-stressed mice and found that RLE alleviated decreases in the number of intestinal goblet cells and amount of hepatic triglycerides. It also decreased the immobility time in the forced-swimming test and activation of microglia in the brain, suggesting that RLE has beneficial effects on stress-induced dysfunctions.

Sake cake (sake-kasu) ingestion increases branched-chain amino acids in the plasma, muscles, and brains of senescence-accelerated mice prone 8.

To examine metabolic effects of sake cake ingestion, plasma and tissues were analyzed in senescence-accelerated mice prone 8 (SAMP8) fed a sake cake diet. As a result, branched-chain amino acids (BCAA) were found to be significantly higher in the plasma, gastrocnemius muscles and brains of the sake cake group than in the control group. Mice in the sake cake group showed stronger grip strength than the control group.

Anti-diabetic effect of S-adenosylmethionine and α-glycerophosphocholine in KK-A mice.

Six-week-old male KK-A mice received drinking water with S-adenosylmethionine (SAM), α-glycerophosphocholine (GPC), or SAM+GPC for 10 weeks. The serum glucose of SAM+GPC at 15 weeks old, total cholesterol of GPC at 12 weeks old, and triglyceride of GPC at 15 weeks old and of SAM at 16 weeks old were reduced. SAM+GPC reduced serum leptin and food intake.

Carnosic acid attenuates cartilage degeneration through induction of heme oxygenase-1 in human articular chondrocytes.

Osteoarthritis (OA) is common age-associated disease, and associated with joint pain, mobility limitations and compromised overall quality of life. OA treatment is currently limited to pain management and joint arthroplasty at end stage disease. Oxidative damage to cartilage extracellular matrix and cells is an important mechanism in joint aging and OA pathogenesis.

The delaying effect of alpha-glycerophosphocholine on senescence, transthyretin deposition, and osteoarthritis in senescence-accelerated mouse prone 8 mice.

Administration of alpha-glycerophosphocholine (GPC), a choline compound in food, is expected to contribute to human health. In this study, we evaluated its effect on aging in senescence-accelerated mouse prone 8 (SAMP8) mice. Male SAMP8 mice had free access to a commercial stock diet and drinking water with or without GPC (0.

Carnosic acid protects starvation-induced SH-SY5Y cell death through Erk1/2 and Akt pathways, autophagy, and FoxO3a.

Carnosic acid (CA) is recognized as a unique neuroprotective compound in the herb rosemary, since it induces expression of antioxidant enzymes including heme oxygenase-1 (HO-1), γ-glutamylcysteine synthase (γ-GCS), and glutathione S-transferase (GST) via activation of nuclear factor erythroid 2-related factor 2 (Nrf2), which is a nuclear transcription factor. In this study, we examined the cytoprotective effects of CA against starvation. We found that CA protected starvation-induced SH-SY5Y cell death by activating Akt and extracellular signal-regulated kinase 1/2 (Erk1/2).
