Chronic moderate alcohol drinking alters insulin release without affecting cognitive and emotion-like behaviors in rats.

Because the consumption of alcoholic beverages prevails in society, its effects on diabetes risk is a subject of interest. Extant literature on this issue often disagrees. Here, we probed the effects of chronic moderate ethanol consumption on glucose metabolism in rats. The effect of chronic moderate alcohol drinking on depression- and anxiety-like behaviors and memory was also explored. Adolescent male and female Long-Evans rats consumed saccharin-sweetened 5% (1 week) and 10% ethanol (7 weeks) under a 7.5-h/day (Monday-Friday) access schedule. This exposure was followed by sucrose preference

Anxiolytic activity of aqueous extract of Camellia sinensis in rats.

OBJECTIVES: The present study was undertaken to evaluate anxiolytic effect of Camellia sinensis (CS) and possible mechanism on acute and chronic administration in rats. MATERIALS AND METHODS: Eight groups of rats with six in each group were used. Group I served as control. Group II received diazepam (1 mg/kg). Groups III, IV, and V received CS in doses of 3.3, 16.5, and 33 mg/kg, respectively.

Each animal was tested initially in the EPM and th

[Anxiety-like behaviors induced by chronic administration of the synthetic cannabinoid 4F-ABUTINACA in rats and the underlying mechanisms].

OBJECTIVES: To elucidate the Δ⁹-tetrahydrocannabinol (THC)-like discriminative stimulus effects of 4F-ABUTINACA and to investigate the potential mechanisms underlying anxiety-like behaviors induced by chronic 4F-ABUTINACA administration. METHODS: A THC drug discrimination procedure was used in adult male rats to evaluate the THC-like discriminative stimulus effects of 4F-ABUTINACA and the effects of the cannabinoid receptor type 1 (CB1) antagonist rimonabant on these effects. In a separate cohort, rats received intraperitoneal injections of 4F-ABUTINACA at a high dose (2 mg/kg) or a low dose

Developmental Deficiency of Oligodendrocytes and Myelination in the Central Nervous System of the Fetal Alcohol Syndrome Mouse Model.

BACKGROUND: Fetal alcohol spectrum disorder (FASD) is a severe condition characterized by physical and neurodevelopmental abnormalities in the fetus resulting from prenatal alcohol exposure (PAE) or prenatal and lactation alcohol exposure (PLAE). Behavioral abnormalities associated with white matter damage have been extensively investigated in FASD patients and animal models, which suggested the involvement of myelination in FASD pathology. However, the impact of FASD on oligodendrocytes (OLs) and myelination within the central nervous system (CNS) and the underlying mechanisms are little disc

Catechin Protects against Lipopolysaccharide-induced Depressive-like Behaviour in Mice by Regulating Neuronal and Inflammatory Genes.

BACKGROUND: Many studies have suggested that tea has antidepressant effects; however, the underlying mechanism is not fully studied. As the main anti-inflammatory polyphenol in tea, catechin may contribute to the protective role of tea against depression. OBJECTIVE: The objective of this study is to prove that catechin can protect against lipopolysaccharide (LPS)-induced depressive-like behaviours in mice, and then explore the underlying molecular mechanisms. METHODS: Thirty-one C57BL/6J mice were categorized into the normal saline (NS) group, LPS group, catechin group, and amitriptyline gro

Molecular and behavioral effects of Acamprosate in male rats with sodium salicylate-induced tinnitus.

BACKGROUND: Imbalance in inhibitory and excitatory neurotransmitters have been reported in tinnitus. Acamprosate modulates the excitatory and inhibitory neurotransmission in the nucleus accumbens (NAc). This study aims to assess the effect of Acamprosate on tinnitus, anxiety, depression, and molecular changes in nucleus accumbens (NAc), in Sodium-Salisylate (S-salicylate) model of tinnitus. METHODS: Forty-four adult male wistar rats were used in this study. The study included Control, Saline, and S-salicylate groups during the first week, which then subdivided into five groups as Control, Sal

Focused Ultrasound Combined With Microbubbles Attenuate Symptoms in Heroin-Addicted Mice.

OBJECTIVE: To explore the efficacy and mechanisms of stimulating the nucleus accumbens (NAc) in heroin-addicted mice using focused ultrasound and microbubbles (MBs). METHODS: The conditioned place preference (CPP) method was employed to establish a heroin-addicted mice model. Mice were randomized into control (C), heroin (H), heroin + ultrasound (H + U) and H + U + MBs.

Knockdown of thrombospondin 2 inhibits metastasis through modulation of PI3K signaling pathway in uveal melanoma cell line M23.

BACKGROUND: Chronic unpredictable mild stress (CUMS) has been shown to exacerbate atherosclerosis, but the underlying mechanism remains unknown. Adipose tissue is an energy storage organ and the largest endocrine organ in the human body, playing a key role in the development of cardiovascular disease. In this research, it was hypothesized that CUMS may exacerbate the development of atherosclerosis by inducing the hypertrophy and dysfunction of white adipocytes. METHODS: The CUMS-induced atherosclerosis model was developed in Western diet-fed apolipoprotein E (ApoE)-/- mice. White adipose tiss

Behavioral, Transcriptomic, and Neuroinflammatory Effects of Sleep Deprivation: Insights From Separate Acute and Chronic Experimental Paradigms.

BACKGROUND: Depression is a global health burden associated with sleep disruption and inflammation. While acute sleep deprivation (ASD) can alleviate depressive symptoms, chronic sleep deprivation (CSD) is a risk factor for mood disorders. However, the contrasting mechanisms underlying these opposing outcomes remain poorly understood. METHODS: We integrated behavioral profiling, multi-region transcriptomics, and multiplex cytokine analysis to separately characterize the effects of ASD in a pain-depression comorbidity model and CSD in normal mice. Adult male C57BL/6J mice (n = 6 per group) wer

Intracisternal IGF-1 gene delivery attenuates early anxiety-like behavior but not dopaminergic neurodegeneration in a 6-OHDA rat model of parkinsonism.

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons, leading to a spectrum of motor and non-motor symptoms. In addition to the motor deficits serving as the primary criteria for diagnosis, mood and anxiety disorders also play a significant role in shaping the prognosis and overall disease progression in PD. OBJECTIVES: In this study, our aim was to characterize the progression of anxiety-like behavioral deficits in a rat model of neurotoxicity induced by 6-hydroxydopamine (6-OHDA) and to investigate insulin-like gr

Early overfeeding and adult anhedonia: Impact of neonatal nutrition on hedonic food regulation in male rats.

The aim of our study was to analyze the impact of early-life overnutrition and the exposure in adulthood to a cafeteria diet (CAF) on eating behavior and on the expression of key genes involved in the regulation of food intake. Male Wistar rats were raised in small (SL, 4 pups/dam) or normal litters (NL, 10 pups/dam), fed a control diet (CON) until postnatal day (PND) 90. Then, they received CON or CAF for 11 weeks (NL-CON, NL-CAF, SL-CON, SL-CAF; 12±2 rats/group). Body weight, food intake and behavioral tests (Elevated Plus Maze: EPM, Sensory-specific satiety: SSS) were assessed. At PND167, t

Suppression of ovarian hormones in adolescent rats has no effect on anxiety-like behaviour or c-fos activation in the amygdala.

In humans, sex differences in mood disorders emerge during adolescence, with prevalence rates being consistently higher in females than males. It has been hypothesised that exposure to endogenous ovarian hormones during adolescence enhances the susceptibility of females to mood disorders from this stage of life onwards. However, experimental evidence in favour of this hypothesis is lacking. In the present study, we examined the long-term effects of suppressing adolescent gonadal hormone levels in a group of female Lister-hooded rats via administration of a gonadotrophin-releasing hormone antag

Exposure to di-(2-ethylhexyl) phthalate transgenerationally alters anxiety-like behavior and amygdala gene expression in adult male and female mice.

Phthalates are industrial plasticizers and stabilizers commonly found in polyvinyl chloride plastic and consumer products, including food packaging, cosmetics, medical devices, and children's toys. Di-(2-ethylhexyl) phthalate (DEHP), one of the most commonly used phthalates, exhibits endocrine-disrupting characteristics and direct exposure leads to reproductive deficits and abnormalities in anxiety-related behaviors. Importantly, increasing evidence indicates that the impacts of DEHP exposure on reproduction and social behavior persist across multiple generations. In this study, we tested the

Neurotransmitter-mediated anxiogenic action of PACAP-38 in rats.

The action of PACAP-38 was studied by measuring the anxiogenic-anxiolytic behavior of rats in an elevated plus maze. PACAP-38 was administered into the lateral brain ventricle and the behavior of the animals was measured 3h later. The possible involvement of transmitters was measured by pretreating the animals with receptor blockers which alone did not influence the task, but in the doses used were effective with other neuropeptides. The receptor antagonist PACAP 6-38 (a PAC 1/VPAC2 receptor antagonist of PACAP-38 receptor), haloperidol (a non-selective dopamine receptor antagonist), phenoxybe

In vivo and In Silico Assessment of Acampe papillosa (Lindl.) Lindl. Seed Extract: A Multi-Pharmacological Approach.

Acampe papillosa (Lindl.) Lindl., an epiphytic orchid, has been traditionally utilized in ethnomedicine for the management of pyrexia, otalgia, rheumatism, and neuralgia. This work intends to figure out the in vivo neuropharmacological, antinociceptive, and antipyretic potentials of the methanolic extract of A. papillosa seeds (ME-APS) along with computational approaches. Phytochemical screening of ME-APS was analyzed through GC-MS. Elevated plus maze (EPM) and hole board (HBT), forced swim (FST), and tail suspension (TST) tests were used to evaluate anxiolytic and antidepressant effects, wher
