“…Those were also supported by the histological analysis, showing that the mucosal thickness and muscularis thickness in colon of mice fed with BP-DF significantly increased, compared with HFD-induced obese mice. Additionally, these changes may be relevant with absorption and metabolism capacity of intestinal mucosa epithelium, and reflect the protective effects of BP-DF on intestinal tract (Duan, Wang, Zhang, Liu, & Ding, 2018).…”

Banana (Musa nana Lour.) have the effect of anti‐obesity and lipid modulating properties. However, the influences of banana pulp dietary fibers (BP‐DF) on metabolic syndrome (MetS) and gut microbiota (GM) are unknown. In this research, we explore a novel strategy for dietary BP‐DF on attenuation of lipid metabolic disease, GM disorder, and associated mechanisms in high‐fat diet (HFD) mice. BP‐DF can strongly suppress on HFD caused body weight and epididymal fat mass gain, and significantly improved serum lipid profiles, liver lipid profiles, and intestinal function. BP‐DF also significantly improved fecal short‐chain fatty acids formation and fecal ammonia content. BP‐DF impacted the intestinal microorganism at all kinds of taxonomic levels by increasing the proportions of beneficial Lactobacillus, Bacteroidales _S24_7_group, and Alloprevotella and decreasing the disease or obesity associated Sutterella, Streptococcaceae, and Erysipelotrichaceae. The experiments show that BP‐DF may use as a functional ingredient for preventing obesity, MetS, and intestinal microorganism imbalance. Practical applications Obesity result in many metabolic complications, and it poses a great threat to people's health. Nowadays, the introduction of DF may lead to the development of a new strategy in the treatment of obesity and its metabolic syndrome. Our experiments findings show that BP‐DF may use as a functional ingredient for preventing obesity, MetS, and intestinal microorganism imbalance. Therefore, BP‐DF can be applied to the development and production of functional food, and can also be used as an important food functional ingredient, which can be added to various food, such as bread, noodles, baked goods, cakes, etc., to improve its nutritional value.

“…The 0.5‐cm‐long intestine segments were cut and fixed in a 4% paraformaldehyde solution. After rinsing with running water, the tissue samples were dehydrated in a series of ethanol solutions (70%, 80%, 90% and 100%) (Duan et al., 2018). The samples were then transferred to xylene for transparency and embedded in paraffin.…”

Five dietary lipid sources (fish oil, soybean oil, palm oil, rapeseed oil and linseed oil) were evaluated in juvenile red claw crayfish, Cherax quadricarinatus, based on the response of growth, antioxidant capacity, intestine histology, whole‐body composition, fatty acid nutrition and lipid metabolism. Crayfish were fed in quadruplicate net cages for 8 weeks. Crayfish fed diets with fish oil, soybean oil and linseed oil obtained significantly higher weight gain and specific growth rate than those fed the other two diets. Survival, condition factor and hepatosomatic index were not significantly affected by lipid sources. Lipid sources also do not affect the whole‐body composition of crayfish. Serum SOD, T‐AOC and GSH‐PX activities of crayfish fed the palm oil and rapeseed oil diets had a significantly lower value than those fed other diets. The minimum concentrations of MDA have been observed in crayfish fed the soybean oil diet. The activity of ACC in the hepatopancreas of crayfish fed the linseed oil diet showed the highest value, and the CPT‐1 activity was not significantly affected by different lipid sources. Crayfish fed the soybean oil diet showed significantly higher TC and TG contents in hepatopancreas than those fed other diets. Crayfish fed linseed oil diet had a significantly higher percentage of EPA, C18:3n−3 and Σn−3 PUFA in muscle than those fed other treatments. Most of the fatty acid compositions in the hepatopancreas had a close correlation to fatty acid compositions in diets. All findings in this study indicate that soybean oil is the advantageous lipid source for juvenile C. quadricarinatus which can reflect in satisfactory growth performance, antioxidant capacity and fatty acid nutrition of edible tissues.

“…In L. vannamei , LPS is often used to study its toxicity to innate immunity in animals. Previous studies showed that LPS injection could damage the intestine mucosal structure and decrease the digestive enzymes activity (Duan et al, 2018). Moreover, morphologic, physiological and immunological changes occurred after short‐term in vitro exposure of haemocytes to LPS (Xian et al, 2009).…”

“…It has been reported that the survival rate of shrimp was raised by adding LPS in diets when exposed to Vibrio, which indicating that LPS was used as an immunostimulant in shrimp farming and had good prospects for application (Rungrassamee et al, 2013). Conversely, LPS injection destroyed the intestine barrier and caused inflammation responses of shrimp haemocytes (Duan et al, 2018;Xian et al, 2009). Currently, few studies mentioned the mechanism of LPS injection to the immune and physiological responses of hepatopancreas in L. vannamei.…”

Litopenaeus vannamei (L. vannamei), also known as Pacific white shrimp, is one of the largest cultured shrimp species in the world, accounting for more than 70 per cent of global shrimp production for its rapid growth, tender meat and high nutritional value (Loker et al., 2010). Unfortunately, L. vannamei is susceptible to bacteria which can lead to massive death of shrimp, and cause huge economic losses to the farming industry (Walker & Winton, 2010). Therefore, it is necessary to properly understand the pathogenesis of bacterial
