“…Additionally, glycine and L-arginine have the ability to prevented endothelial dysfunction [10,11]. In addition to free amino acids including taurine, other components in the clams such as minerals and betaine may contribute to the prevention effects of AS and GA on endothelial dysfunction [33,34]. Betaines are known to convert homocysteine, which is reported to have adverse effects by disturbing endothelial function, to methionine as a methyl donor [35].…”

Endothelial dysfunction is directly involved in consequence of various metabolic syndromes such as diabetes and hypertension. In this study, we investigated the preventive effects of two ark clams [ark shell (AS, Scapharca subcrenata) and granular ark (GA, Tegillarca granosa)] on endothelial dysfunction induced by a high-fat diet. Wistar rats were divided into four groups as follows: control (normal diet), HF (high-fat diet), AS (high-fat diet + 5% AS powder), and GA (high-fat diet + 5% GA powder) for 12 weeks. AS and GA diets enhanced vascular reactivity of the rat thoracic aorta and significantly increased expression levels of vascular relaxation-related proteins (p-Akt-ser473 and p-eNOS-ser1177). Ark clam supplement reduced endothelin-1 expression level, as compared to the HF group. Additionally, AS and GA showed a trend of improving insulin sensitivity compared to HF. Our results suggest that AS and GA enhance vascular reactivity and ameliorated endothelial dysfunction induced by a high-fat diet.

The Pacific oyster (Crassostrea gigas) and the Portuguese oyster (C. angulata) are important oyster species for commercial aquaculture. In this study, three stocking density regimes, including 20, 30 and 40 oysters/basket, were used to study the effects of stocking density on growth performance, survival rate and lipid nutritional quality of diploid and triploid C. gigas and C. angulata. The experiment lasted 163 days, from to 22 November 2011 to 3 April 2012. The main findings of this study are as follows: (1) C. gigas has growth advantage over C. angulata in Shantou waters; (2) geographic origin of the oysters has an impact on the overall performance of diploid and triploid oysters; (3) triploids are generally no growth and survival advantage over diploids in spring and summer; (4) oysters at low stocking density were generally outperformed those at high stocking density; (5) lipid composition of oysters is not affected by ploidy and stocking density; (6) in Shantou waters, C. angulata is more nutritious than C. gigas. This study compares the performance of C. gigas and C. angulata triploidy for the first time. The findings of this study can provide useful information to be applied in oysters aquaculture.

“…Tegillarca granosa is also known as blood clam, one of the most important aquaculture bivalve species in China 10 . T. granosa is rich in amino acids, fatty acids, and mineral nutrients, especially iron 11 . Indeed, it has long been considered that consumption of T. granosa is good for alleviating anemia for Chinese people, which is likely attributed to its abundant in high‐quality iron 12 .…”

Background Iron‐deficiency anemia is one severe micronutrient malnutrition and has captured worldwide attention. This study evaluated the in vitro iron absorption of two iron‐binding proteins (hemoglobin and ferritin) from Tegillarca granosa. In addition, the protein structure–iron absorption relationship and the regulatory effect of hepcidin on cellular iron absorption were explored. Results Our findings revealed that both hemoglobin and ferritin extracted from T. granosa contained abundant iron‐binding sites, as evidenced by stronger peaks in amide I and II regions compared with the two proteins from humans. Less β‐sheet (27.67%) structures were found in hemoglobin compared with ferritin (36.40%), probably contributing to its greater digestibility and more release of available iron. This was confirmed by the results of Caco‐2/HepG2 cell culture system that showed iron absorption of hemoglobin was 26.10–39.31% higher than that of ferritin with an iron content of 50–150 μmol L−1. This high iron absorption of hemoglobin (117.86–174.10 ng mg−1) could also be due to more hepcidin produced by HepG2 cells, thereby preventing ferroportin‐mediated iron efflux from Caco‐2 cells. In addition, the possible risk of oxidative stress was evaluated in cells post‐iron exposure. In comparison with ferrous sulfate, a common iron supplement, Caco‐2 cells treated with the iron‐binding proteins had a 9.50–25.73% lower level of intracellular reactive oxygen species, indicating the safety of hemoglobin and ferritin. Conclusion Collectively, the data of this research would be helpful for understanding the key features and potential of developing hemoglobin and ferritin from T. granosa as novel iron supplements. © 2022 Society of Chemical Industry.
