Article Abstract
Docosahexaenoic acid (DHA) has an important role in brain development and functionality. Therefore, this study aimed to evaluate the effects of DHA-concentrated fish oil on the cognitive function of puppies. Twelve 3-month-old puppies were included, blocked by breed and randomly distributed into two groups: the Control Group (CG), without supplementation, and the Experimental Group (EG), supplemented with 40 mg DHA/kg BW/day. The object discrimination test was used, with a normal stage (NS) and a reverse stage (RS), and blood samples were collected to evaluate the serum polyunsaturated fatty acid (PUFA) concentration and total antioxidant capacity (TAC) before (T0) and 30 (T1), 60 (T2) and 90 (T3) days after beginning the study. For the NS, there were effects of treatment ( = 0.0039) and time ( < 0.0001), in which the correct answer frequency in the EG was higher than the CG. The serum eicosapentaenoic acid (EPA) + HA concentrations at T1, T2 and T3 were higher than at T0 for the EG ( = 0.0159), in addition, EG showed higher serum EPA + DHA concentrations than CG at T2 ( = 0.0245). The TAC values were similar between the groups ( = 0.3211). It was concluded that the cognitive function of puppies can be enhanced with DHA-concentrated fish oil supplementation without increasing the serum lipid oxidation.

Microcystins (MCs) are cyclic heptapeptides originating from various cyanobacteria in eutrophic aquatic environments. Their potential consequences on ecosystems and public health underscores the need to explore MCs' occurrence. In this study, liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) analysis and a suspect screening workflow supported by open-source tools were employed for the determination of MCs in freshwater and biota samples from a eutrophic dam in Uruguay.
Asthma, is a common, significant and diverse condition marked by persistent airway inflammation, with a major impact on human health worldwide. The predisposing factors for asthma are complex and widespread. The beneficial effects of omega-3 (n-3) polyunsaturated fatty acids (PUFAs) in asthma have increasingly attracted attention recently.
Objective: To explore the differences in fat and fatty acids content between freshwater and saltwater fish.
Methods: The fat and fatty acids content in 83 fish meat samples from four regions(Hainan, Jiangsu, Fujian, and Guangxi) were detected by national standard method. Mann-Whitney U tests and t-tests were used to compare the differences in fat and major fatty acid content between freshwater and saltwater fish.
Objective: To analyze the fatty acid content of Jiangnan dishes in Hangzhou.
Methods: Based on the order frequency records from an online platform, two popular Jiangnan cuisine restaurants were selected for monitoring. Fat extraction was performed on three types of dishes: purely vegetarian, mixed vegetarian and non-vegetarian, and purely non-vegetarian, using acid hydrolysis.
Objective: To describe the food intake among adult residents in 10 provinces(autonomous regions) of China.
Methods: Data was collected from the financial project China Development and Nutrition Health Impact Cohort Survey in 2022-2023. The method of three consecutive 24-h dietary recalls and weighing were used to collect foods and condiments intake data.
