Chinese Soft-Shelled Turtle Oil in Combination With Swimming Training Improves Spatial Memory and Sports Performance of Aging Rats

Abstract

In this study, waste fat from the Chinese soft-shelled turtle (Pelodiscus sinensis) was used as the raw material, and soft-shelled turtle oil (SSTO) was extracted by water heating. Analysis of the fatty acid composition of SSTO revealed that unsaturated fatty acids (UFAs) comprised more than 70% of the oil, of which more than 20% were omega-3 poly-UFAs. DPPH radical scavenging and cellular ROS assays confirmed the reduction of oxidative stress by SSTO. In D-galactose-induced aging rats, SSTO feeding alone or in combination with swimming training resulted in improved memory and physical strength. In addition, SSTO feeding with swimming intervention significantly increased the SOD level and maintained better blood pressure in the aged rats. The serum DHEAS and soleus muscle glycogen level were also highly correlated with SSTO feeding and swimming training. In conclusion, the results of this study demonstrated that SSTO has the potential to be developed into a health food that exerts anti-aging effects, and those effects are stronger when combined with daily swimming exercise.

Tea Seed Kaempferol Triglycoside Attenuates LPS-Induced Systemic Inflammation and Ameliorates Cognitive Impairments in a Mouse Model

“…LPS has been used to experimentally induce memory impairments and neuroinflammatory responses [ 22 , 35 ]. We employed the Y-maze test to assess the effects of KXRG feeding on LPS-induced memory impairments in mice [ 36 ]. The results showed that daily administration of KXRG (25 and 50 mg/kg) improved LPS-induced memory impairments, including improvement in the desire to explore new environments, greater mobile activity, reduced duration spent looking for food, improved memory, and improved cognition ( Figure 5 ).…”

Antibacterial and antibiofilm effects of Camellia oleifera seed dreg extract and its application in cosmetics

“…Assessing free radical scavenging activity of sample in vitro and in cultured CCD‐966SK cells. The protocol of DPPH and ROS analysis was carried out according to the methods previously published by our laboratory 22,23 . Briefly, for DPPH test, the stock DPPH solution was prepared in 95% methanol, mixed evenly with sample at indicated concentrations, and kept them away from light for 30 min.…”
