Summary: The study investigated the effects of the endocannabinoid metabolism inhibitor URB597 on social and non-social memory in Lister Hooded rats. While URB597 did not impact memory, it did have subtle effects on social behavior during social interaction testing. This highlights the importance of considering strain and behavioral composition when studying drug effects on social behavior.

Summary: Endocannabinoid transmission plays an important role in treating anxiety-related disorders through the regulation of fear extinction. The inhibition of FAAH can enhance extinction by increasing anandamide levels, while inhibiting MAGL can impair extinction by elevating 2-arachidonoylglycerol levels. However, the specific effects of endocannabinoids on fear relapse and extinction resistance are still uncertain.

Summary: In addition to genetic factors, environmental factors also play a significant role in the development of attention deficit/hyperactivity disorder (ADHD). This study used Lister hooded rats as ADHD model animals and found that environmental conditions had a notable impact on the behavior and neural activity of the rats. Specifically, rats raised in an enriched environment showed improved ADHD-like behaviors, which were associated with reduced neuronal activity in the medial prefrontal cortex.

Summary: This study investigates the relationship between changes in size and complexity of familiar objects and the exploratory activity regulation in rats. The rats responded to new tunnels with increased exploration, initially reacted to changes in size but then refocused, and showed pronounced curiosity towards increased complexity. The data suggests that curiosity in rats is at least two-dimensional: activational and cognitive.

Summary: This study examined the relationship between gambling strategies and behavioral and neural correlates using the rat Gambling Task (rGT). The results showed that rats displayed stable gambling strategies in the rGT, which were associated with brain regions important for reward networks. Additionally, rats with risky gambling strategies differed in brain functional connectivity from those with strategic and intermediate strategies.

Summary: The study found that patients with psychosis in urban areas are more socially isolated when surrounded by more people, which could impact their clinical outcomes. There were no associations found between social contacts or satisfaction with friendships with social deprivation or fragmentation indexes.

Summary: Social adversity during childhood and adolescence may increase the likelihood of mental illnesses. A study on rats using the Chronic Early-Life Social Isolation (CELSI) model found that rats who experienced post-weaning social isolation showed stronger spatial learning and memory abilities. The study also observed an increase in expression of PSD-95, a key neuronal protein, in socially isolated male rats. These findings suggest that CELSI may enhance hippocampal-dependent behavior.

Summary: This study examined the effects of ketamine administration combined with isolation in inducing schizophrenia-like symptoms in male albino rats. Results showed significant differences in behavior tests and oxidative stress levels between the ketamine + isolation group and the control or ketamine + social housing group. Additionally, adding aripiprazole treatment to the ketamine + social isolation group further reduced positive schizophrenia-like symptoms. This research suggests a potential model capable of illustrating both positive and negative symptoms of schizophrenia.

Summary: Social isolation and loneliness are often overlooked conditions that have a negative impact on quality of life, overall health, and mortality. This review discusses the health consequences of these conditions, including potential causes, pathophysiological processes, associations with non-communicable diseases, and effects on health-related behaviors. It also explores current and novel management strategies. Healthcare professionals should be knowledgeable about social isolation and loneliness, thoroughly assess patients, and provide education and treatment options through shared decision-making. Further research is needed to better understand the underlying mechanisms and improve treatment strategies for these conditions.

Summary: Depression is a common mood disorder affecting over 260 million people worldwide. Dysbiosis of the gut microbiome, which modulates neuro-biochemical metabolism through the microbiome-gut-brain axis, has been associated with the development of depressive-like behaviors. Fecal microbiota transplantation (FMT) has been proposed as a potential therapeutic solution for depression, and this study investigated its therapeutic efficiency and mechanisms.

Summary: This systematic review investigates the use and efficacy of ketogenic diets, modified Atkins diet, and medium-chain triglyceride diet in patients with epilepsy, Alzheimer's disease, and Parkinson's disease. The results show that ketogenic diets can reduce seizures in epilepsy patients, modified Atkins diet can improve memory in Alzheimer's patients, and medium-chain triglyceride diet can enhance motor and nonmotor functions in Parkinson's patients.

Summary: The study aimed to evaluate the relationship between the therapeutic effects of glucagon-like peptide-1 receptor agonist liraglutide and cytokines. The results showed that prediabetic patients treated with clozapine or olanzapine had increased levels of inflammatory cytokines in their serum, further confirming the link between inflammation and type 2 diabetes. However, treatment with liraglutide did not affect these cytokines.

Summary: This study successfully established a rat model based on the genetic-environmental interaction, which exhibited phenotype characteristics similar to human AD in terms of cognitive function, brain microstructure, and immunohistochemistry. The genetic factor (APP mutation) and the environmental factor (acrolein exposure) accounted for 39.74% and 33.3% of the AD-like phenotypes in the model, respectively.

Summary: This study examines the functional connectivity changes in individuals with sudden sensorineural hearing loss (SSNHL) at the integrity, network, and edge levels. The findings reveal reduced intranetwork connectivity strength and increased internetwork connectivity in SSNHL patients. These alterations are associated with the duration of SSNHL and Tinnitus Handicap Inventory scores. The study provides crucial insights into the neural mechanisms of SSNHL and the brain's network-level responses to sensory loss.

Summary: In the early stages of SAD, memory impairment is strongly correlated with cortical levels of soluble amyloid-beta peptide oligomers. A beta disrupts glutamatergic synaptic function and leads to cognitive deficits. This article describes the pathogenic mechanisms underlying cerebral amyloidosis, involving amyloid precursor protein synthesis, A beta residue clearance processes, and the role of specific molecules.

Summary: Depression has a higher incidence in women compared to men, and this study investigated the impact of sex on depressive behaviors and underlying mechanisms using a corticosterone-induced depression model in mice. The results showed sex-specific anxiety and depression behaviors in the model group, as well as differences in protein expression and neurotransmitter levels between male and female mice. These findings enhance our understanding of sex-specific differences in depression and support tailored interventions.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.

Summary: This study observed changes in brain infarction and blood vessels in rats during neonatal hypoxic ischemic encephalopathy (NHIE) modeling using Transcranial Doppler Ultrasonography (TCD). Longer duration of hypoxia was associated with more severe nerve damage. TCD can dynamically monitor cerebral infarction after NHIE modeling, which may serve as a useful auxiliary method for evaluating animal experimental models.
