Summary: This study investigated the potential influences of n-3/n-6 polyunsaturated fatty acids (PUFAs) as supplements in VPA-induced autistic rat model. The results showed that supplementation with n-3/n-6 PUFA (1:5) reduced repetitive stereotyped behaviors and social deficits in neonatal rats exposed to VPA, likely due to improved inflammatory responses through the alteration of STAT3 signaling. This study provides evidence for the use of n-3/n-6 PUFAs in the treatment of autism in humans.

Summary: Postprandial metabolism plays significant roles in various pathological conditions, and the n-6/n-3 polyunsaturated fatty acid ratio is closely associated with physiological disorders. This study investigated the effects of high fat meals with different n-6/n-3 PUFA ratios on postprandial metabolism in normal control and hypertriglyceridemia rats. The results showed that the n-6/n-3 PUFA ratio influenced the postprandial response of triglyceride, total cholesterol, tumor necrosis factor alpha, malondialdehyde, and reactive oxygen species in both normal control and hypertriglyceridemia rats.

Summary: This study found that factors such as high education levels, older age, consumption of fish and seafood, and non-smoking are significantly associated with serum fatty acid concentrations in pregnant women, leading to a better omega-3 fatty acid profile. Further research is needed to explore the health consequences of these findings.

Summary: This study investigated the effect of different n-6/n-3 polyunsaturated fatty acid (PUFA) ratios on serum fatty acid composition, microbiota, and their metabolites in the intestine of pigs. The results showed that a lower dietary n-6/n-3 PUFA ratio improved serum fatty acid composition and metabolome-microbiome responses in Heigai pigs. This study provides new insights into regulating pig metabolism and understanding the interaction between host and microbes in pigs.

Summary: The study demonstrates that adding Aurantiochytrium sp. to diets can significantly improve the growth performance and immune response of Trachinotus ovatus. With increased microalgae content, the growth rate and feed utilization efficiency of fish were enhanced, along with increased fatty acid content in blood and tissues, resulting in improved immunity and disease resistance in fish.

Summary: The intake of fatty acids affects the composition of lipids in the body. In this study, rats were fed a peanut-oil-based diet for 33 days after weaning to investigate the effects of mild (n-3) deficiency on the lipid composition of various organs and feces. Results showed a lower level of docosahexaenoic acid (DHA) in the (n-3) deficient group compared to the control group, but no difference in DHA content was observed in the eyes and feces. This study highlights the importance of adequate maternal nutrition for a healthy fatty acid balance in rats.

Summary: The gut-liver axis is crucial in the development of NAFLD and FFAR4 may act as a bridge between the gut and liver. In this study, FFAR4 deficiency in mice with high endogenous n-3 PUFAs blocked the protective effects on intestinal barrier dysfunction and hepatic steatosis. FFAR4 deficiency also affected the gut microbiota and various metabolic pathways associated with NAFLD aggravation. These findings highlight the role of FFAR4 in the treatment of NAFLD through the gut-liver axis.

Summary: This study found that a combination of folic acid and n-3 polyunsaturated fatty acids has a better preventive effect on neural tube defects induced by maternal diabetes compared to folic acid alone. The combination treatment reduced neuroepithelial cell apoptosis and regulated the expression of key genes involved in diabetes-induced defects. The combination therapy also attenuated diabetes-induced hypermethylation and overexpression of genes related to one-carbon metabolism and lowered levels of homocysteine.

Summary: Recent findings suggest that changes in brain lipid composition during aging can affect the integrity and protein signaling of lipid rafts, leading to memory impairment. However, a n-3 LCPUFA-enriched diet has been shown to improve cognitive function and stabilize the lipid composition of hippocampal lipid rafts in aged mice. These findings suggest that n-3 LCPUFA supplementation may have a rejuvenating effect on the microenvironment of lipid rafts, enhancing cognitive performance.

Summary: The study found that consuming two portions of fish per week significantly increased concentrations of EPA, DHA, and total n-3 PUFA in women of childbearing age, with a lower n-6:n-3 ratio compared to those consuming no fish or one portion per week. However, fish consumption did not have a significant effect on biomarkers of oxidative stress, inflammation, and lipid profile in the current study.

Summary: The review found that supplementation of n-3 PUFAs has a modest beneficial effect on depressive symptoms, particularly in individuals with longer treatment duration and those without depression or with mild to moderate depression. However, there are differences in effects based on different EPA dosages, and the overall quality of evidence remains insufficient.

Summary: This study investigates the effects of dopamine transporter (DAT) silencing on brain structure, function, and behavior using a rat model. The results suggest that constitutive DAT blockade leads to brain changes associated with impaired action inhibition control and motor hyperactivity, which are relevant for neuropsychiatric disorders such as ADHD, schizophrenia, and OCD. The study provides multimodal evidence for prefrontal-midbrain decoupling and striato-cerebellar neuroplastic compensation as transdiagnostic mechanisms of hyperdopaminergia.

Summary: Advances in automation and technology have increased the number of methods and systems available for monitoring locomotor activity and behavior in animals. This review discusses existing automated methods that allow for the measurement of locomotor activity and behavior in rodents in their natural laboratory environment. The review also evaluates the suitability of these methods for group-housed animals, in accordance with ethical guidelines, while highlighting their limitations.

Summary: In preclinical psychiatry research, the study focused on the severity assessment of a genetically modified rat strain with DAT gene deficiency, showing alterations in behavior patterns and coping difficulties due to the high extracellular dopamine levels. The study aimed to provide evidence for a relative severity assessment for the rat model based on scientific evidence and proposed classifying the rats as moderate according to the criteria of the EU directive 2010/63.

Summary: Two-thirds of individuals experience adversity during childhood, which increases the risk of developing mood and substance use disorders. Animal models are useful for studying the effects of early-life adversity (ELA) on reward deficits. A systematic review and meta-analyses revealed that ELA significantly reduces reward behaviors, particularly in the domains of reward responsiveness and social reward processing.

Summary: Stress-related mental disorders are influenced by genetic factors that determine an individual's susceptibility to negative environments. Using a 5-HTT knockout rat model, researchers investigated the role of mitochondrial dynamics in increased threat anticipation. Their findings revealed impaired mitochondrial dynamics in the amygdala and prefrontal cortex of these rats, suggesting a potential mechanism contributing to the reduced extinction recall observed. The study highlights the importance of mitochondrial dynamics in the development of psychiatric disorders.

Summary: Post-traumatic stress disorder (PTSD) is a psychiatric disorder that can occur following a traumatic event, and the differences in susceptibility between individuals may be attributed to aberrant hippocampal dentate gyrus (DG) function. Using a mouse model, this study found specific structural and functional changes in the ventral DG of trauma-susceptible mice.

Summary: The neurotransmitter GHB is involved in neuronal energy homeostasis and is also used recreationally and medicinally. Little is known about the structure and function of GHB receptor subtypes. This opinion article discusses the potential structural and functional properties of the GHBh1 receptor subtype, which shares similarities with a riboflavin transporter and may have dual functions. Further research into the GHBh1 receptor subtype could lead to new therapeutic possibilities for GHB.
