Objectives: Non-alcoholic fatty liver disease (NAFLD) is a prevalent chronic disorder of the and affects many people worldwide. Intestinal bacteria are thought to be involved in pathological progression NAFLD; therefore, improving intestinal microbiota may important controlling NAFLD. In this study, we assessed effects water-soluble cellulose acetate (WSCA) on non-alcoholic steatohepatitis (NASH) mouse model. Methods: NASH model (STAM mice) was created by streptozotocin injection feeding...

Many studies have shown that low copy number variation (CNV) of the salivary amylase gene (AMY1) and serum concentration are associated with impaired glucose metabolism obesity. We aimed to clarify conflicting results previous by examining AMY1 expression metabolic indices in a homogenous group healthy participants.Sixty non-obese young Japanese women aged 20 - 39 years were examined for CNV, amylase, body mass index (BMI) parameters including glycated hemoglobin (HbA1c), ketones, total,...

Nonalcoholic steatohepatitis (NASH) is characterized by excess lipid accumulation and inflammation in hepatocytes. In this study, to provide insight into the preventive effects of d-allose, a rare sugar, on onset NASH, we designed animal experiments using male STAM mice treated with streptozotocin fed high-fat diet (HFD). Experiments were initiated when reached 5 weeks age lasted 3 weeks. After 3-week protocol, HFD containing d-allose exhibited significantly decreased serum alanine...

The changes in free amino acid (AA) levels blood during the progression from non-alcoholic steatohepatitis (NASH) to hepatocellular carcinoma (HCC) are unclear. We investigated serum AA levels, along with biochemical and histological events, a mouse model of NASH. induced NASH male C57BL/6J mice streptozotocin injection high-fat diet after 4 weeks age (STAM group). chronologically (6, 8, 10, 12, 16 weeks, n=4-12 mice/group) evaluated HCC by analyses. were determined using an analyzer. Serum...

Abstract Objective It is unknown whether low serum levels of salivary and pancreatic amylases are associated with the high combustion carbohydrates or lipids for energy. Elevated blood ketones a respiratory quotient (RQ) can reflect preferential relative to carbohydrates. Therefore, using data from our previous study, we investigated if were ketone level RQ in 60 healthy non-obese young women aged 20–39 years old. Results Serum [3-hydroxybutyric acid (3-HBA) acetoacetic (AA)] inversely...

To acquire fundamental knowledge on menstrual cycle and its intraindividual variation in healthy Japanese female students their association with biological attributes, lifestyle food habit.We asked of a nursing school to keep diary menstruation over 5 consecutive months fill questionnaire consumption frequency some items during the period from November 2012 January 2014.The mean±standard deviation (SD) lengths 180 women (20.4±0.9 yrs) was 34.2±10.5 days. Of these women, 141 had length within...

Lifelong education for dietitians in Japan is based mainly on competencies according to years of experience. Because learning content differs depending the desired position and specialty, training programs that reflect individual needs public health are needed. This study aimed assess via experience promotion. In 2021, an online survey involved promotion prefectures, designated cities, other municipalities throughout was conducted.

Zinc (Zn) deficiency is one of the most common nutritional deficiencies worldwide. It associated with reduced status and has been reported in cases growth retardation, alopecia, decreased serum alkaline phosphatase (ALP). also to occur during total parenteral nutrition (TPN) administration various diseases, such as liver diabetes, kidney disease. We used Zn-deficient mice ICR C57BL/6J strains investigate effects Zn on body, assuming that a healthy person may become deficient either due an...
