Abstract
We evaluated the effects of long-term glycerophosphocholine (GPC) intake on microglia, the blood-brain barrier (BBB), and neurogenesis in senescence-accelerated mice prone 8 (SAMP8). The GPC intake suppressed microglial activation and BBB disruption and sustained doublecortin-positive cells in the hippocampus. The results indicate that GPC intake exerts anti-inflammatory and neuroprotective effects in the brain of aged mice.

Katsumata S, Hayashi Y, Oishi K, Tsukahara T, Inoue R, Obata A, Hirooka H, Kumagai H. Effects of liquefied sake lees on growth performance and faecal and blood characteristics in Japanese Black calves. Animal 2023; 17:100873. [PMID: 37399705 DOI: 10.1016/j.animal.2023.100873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 05/29/2023] [Accepted: 06/01/2023] [Indexed: 07/05/2023] Open
Abstract
Liquefied sake lees, a by-product of Japanese sake, is rich in Saccharomyces cerevisiae, proteins, and prebiotics derived from rice and yeast. Previous studies have reported that Saccharomyces cerevisiae fermentation products improved the health, growth, and faecal characteristics of preweaning calves. This study investigated the effects of adding liquefied sake lees to milk replacer on the growth performance, faecal characteristics, and blood metabolites of preweaning Japanese Black calves from 6 to 90 days of age. Twenty-four Japanese Black calves at 6 days of age were randomly assigned to one of three treatments: No liquefied sake lees (C, n = 8), 100 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (LS, n = 8), and 200 g/d (on a fresh matter basis) liquefied sake lees mixed with milk replacer (HS, n = 8). The intake of milk replacer and calf starter, as well as, the average daily gain did not differ between the treatments. The number of days counted with faecal score 1 in LS was higher than in HS (P < 0.05), while the number of days with diarrhoea medication in LS and C was lower than HS (P < 0.05). The faecal n-butyric acid concentration tended to be higher in LS compared to C (P = 0.060). The alpha diversity index (Chao1) was higher in HS than in C and LS at 90 days of age (P < 0.05). The principal coordinate analysis (PCoA) using weighted UniFrac distance showed that the bacterial community structures in faeces among the treatments at 90 days of age were significantly different (P < 0.05). The plasma β-hydroxybutyric acid concentration, an indicator of rumen development, was higher for LS than in C throughout the experiment (P < 0.05). These results suggested that adding liquefied sake lees up to 100 g/d (on a fresh matter basis) might promote rumen development in preweaning Japanese Black calves.

Abstract
This work presents a revision of the main applications of capillary electromigration methods in food analysis and Foodomics. Articles that were published during the period February 2019-February 2021 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods. Namely, CE methods have been applied to analyze amino acids, biogenic amines, carbohydrates, chiral compounds, contaminants, DNAs, food additives, heterocyclic amines, lipids, secondary metabolites, peptides, pesticides, phenols, pigments, polyphenols, proteins, residues, toxins, vitamins, small organic and inorganic compounds, as well as other minor compounds. The last results on the use of CE for monitoring food interactions and food processing, including recent microchips developments and new applications of CE in Foodomics, are discussed too. The new procedures of CE to investigate food quality and safety, nutritional value, storage and bioactivity are also included in the present review work.

Abstract
Recent lifestyle changes, such as the Westernization of diets and the rise in the prevalence of obesity, with an associated increase in the number of patients with lifestyle-related diseases, have become a social issue. Fermented food has attracted attention as a solution to problems caused by obesity. Sake lees, a byproduct of sake brewing, represent one such food that is expected to have health benefits. In this study, we investigated the effects of sake lees components on preadipocytes (3T3-L1). We cultured preadipocytes in a medium with indigestible sake lees components (ISLCs) to investigate lipid accumulation, analyzed the glycerol 3-phosphate dehydrogenase (GPDH) and LPL activities of those cells, and performed a real-time PCR analysis of the IL6 expression in the cells. The results show that lipid accumulation and GPDH activity were significantly decreased in adipocytes treated with 1.0 mg/mL ISLCs compared to untreated cells. Furthermore, the expression of IL6 in adipocytes treated with 1.0 mg/mL ISLCs was significantly decreased and the lipase activity was significantly increased in adipocytes treated with ISLCs after differentiation. IL6 is known to have multiple functions in adipose tissue. In conclusion, ISLCs were associated with reduced lipid accumulation in adipocytes, with effects on IL6 expression and LPL activity observed throughout the differentiation period.

Abstract
Capillary electrophoresis-mass spectrometry (CE-MS) is now a mature analytical technique in metabolomics, notably for the efficient profiling of polar and charged metabolites. Over the past few years, (further) progress has been made in the design of improved interfacing techniques for coupling CE to MS; also, in the development of CE-MS approaches for profiling metabolites in volume-restricted samples, and in strategies that further enhance the metabolic coverage. In this article, which is a follow-up of a previous review article covering the years 2016-2018 (Electrophoresis 2019, 40, 165-179), the main (technological) developments in CE-MS methods and strategies for metabolomics are discussed covering the literature from July 2018 to June 2020. Representative examples highlight the utility of CE-MS in the fields of biomedical, clinical, microbial, plant and food metabolomics. A complete overview of recent CE-MS-based metabolomics studies is given in a table, which provides information on sample type and pretreatment, capillary coatings, and MS detection mode. Finally, some general conclusions and perspectives are given.

Abstract
Amazake is a traditional Japanese health drink. Here, we examined the effects of amazake on skin in cells and humans. Treatment with sake cake or rice koji suppressed intracellular lipid accumulation in differentiated hamster sebocytes, likely through the reduced expression of peroxisome proliferator-activated receptor-gamma (PPARγ) mRNA. In double-blind, placebo-controlled trial, seventeen Japanese women ingested either amazake or placebo for 4 weeks. Ingestion of the amazake decreased the sebum content compared to the placebo. The questionnaires showed improvements in "face color," "dark circles under the eyes," "glossy hair," and "waking up well", only in the amazake. In accordance with the questionnaires, additional analysis revealed the change in the L* values under the eyes was statistically increased in the amazake compared to the placebo. These results indicate that amazake may decrease sebum content in cells and humans and increase the L* values under the eyes, with some additional beneficial effects in humans.
