Summary: This review comprehensively evaluates the impact of binge drinking on neurocognitive functions, and introduces the use of resting-state functional connectivity and neurite orientation dispersion and density imaging techniques. The study finds that binge drinking is associated with structural and functional anomalies in the brain.

Summary: The study found that peripherally administered oxytocin has inhibitory effects on METH self-administration and reinstatement, with a requirement for vagus nerve signaling involvement, and that this vagal dependency is partially mediated by sex and drug withdrawal.

Summary: Depression causes abnormal brain glucose catabolism due to impaired mitochondrial structure and function. Activation of metabolic enzymes in energy-producing pathways is attempted, but a low TCA cycle activity is observed in depression. The strategy of stable isotope-resolved metabolomics and mitochondrial analysis provides insights for investigating depression mechanisms and developing novel antidepressants.

Summary: This study aimed to investigate the independent and combined effects of chronic heavy methamphetamine (METH) use and having at least one copy of the apolipoprotein E (APOE)-epsilon 4 allele on brain morphometry and cognition, especially in relation to aging. The results showed that METH users, regardless of APOE-epsilon 4 genotype, had lower cognitive performance and specific brain abnormalities compared to non-users. Additionally, APOE-epsilon 4 carriers who were METH users showed the smallest volumes in certain brain regions, suggesting a synergistic effect on brain atrophy.

Summary: Gabapentin (GBP), a GABA analogue, is primarily used as an anticonvulsant for the treatment of partial seizures and neuropathic pain. However, recent studies have shown that GBP can significantly increase the risk of heart diseases. In this study, using a rat model, researchers found that both acute and chronic GBP treatments suppressed cardiovascular function and resulted in abnormal calcium signaling in cardiomyocytes. These findings provide important evidence of the cardiovascular side effects of GBP.

Summary: This study aimed to investigate the cognitive impairment caused by chronic methamphetamine addiction in mice and explore the potential mechanisms. It was found that methamphetamine administration led to poor cognitive performance in mice, which partially recovered after withdrawal. Treatment with melatonin during withdrawal enhanced the recovery by restoring neuronal impairments.

Summary: The study found that exposure to methamphetamine and its cessation can alter the composition of gut microbiota, with the gut bacteria composition returning to normal after cessation. In addition, acute cessation of methamphetamine induced depressive-like behavior, but did not affect anxiety-like behavior.

Summary: This study investigated the effects of exposure to a low concentration of METH on brown trout. The trout exhibited lowered activity and metabolic rate, altered brain and gonad morphology, changes in brain metabolome, and higher levels of melatonin. The findings highlight the complex disturbances in aquatic fauna caused by the presence of METH in the environment.

Summary: Preserving cognitive function and protecting brain structure during aging and neurodegenerative diseases is the goal of non-pharmacologic interventions, such as diet and exercise. This review examines the current trends of diet and exercise interventions and their impact on cognition and brain health. Various diets, including the Mediterranean diet, DASH, MIND, ketogenic diet, intermittent fasting, and weight loss management, as well as exercise approaches such as endurance, resistance, combined programs, yoga, tai chi, and high-intensity interval training, are discussed. While evidence is accumulating regarding the influence of diet and exercise on cognitive performance and brain structure, more research is needed to understand the underlying mechanisms.

Summary: The study found that transcranial photobiomodulation can enhance brain energy metabolism and cognition, particularly reversing aging-related metabolic changes in older rats. Statistical analysis revealed that photobiomodulation significantly improved metabolic pathways in younger rats, especially in excitatory neurotransmission and oxidative metabolism, while restoring altered pathways in older rats.

Summary: The aim of this study was to investigate the role of BDNF and dopamine D3 receptors in the effects of chronic methamphetamine on prepulse inhibition (PPI), an endophenotype of psychosis. The results showed that chronic methamphetamine disrupted PPI regulation in male mice with BDNF haploinsufficiency, regardless of D3 receptor knockout. However, there were no effects of BDNF heterozygosity or D3 knockout on PPI regulation in female mice. These findings suggest a significant involvement of BDNF in the long-term effects of methamphetamine on PPI, particularly in male mice.

Summary: The systematic review found that mind-body exercise modulates brain structure, neural activity, and functional connectivity in regions such as the prefrontal cortex, hippocampus/medial temporal lobe, lateral temporal lobe, insula, and the cingulate cortex. This may explain the beneficial effects of such exercises on health, but more randomized controlled trials with rigorous designs and whole-brain analyses are needed for confirmation.

Summary: The olfactory system is modulated by metabolic factors to drive changes in feeding behavior and energy homeostasis. Inhibiting Kv1.3 in the olfactory bulb can enhance excitability of output neurons and lead to metabolic responses, resulting in changes in body weight and energy metabolism.

Summary: This study presents a promising strategy for scalable production of high-quality extracellular vesicles (EVs) from human mesenchymal stem cells (hMSCs) using 3D aggregates grown under wave motion. The 3D hMSC aggregates promote activation of different pathways involved in EV secretion. Comparison with 2D hMSC-EVs reveals that the quantity of 3D hMSC-EVs is significantly enhanced, with smaller sizes, higher expression of miR-21 and miR-22, and an altered protein cargo. Functionally, 3D hMSC-EVs rejuvenate senescent stem cells and exhibit enhanced immunomodulatory potentials.

Summary: Accumulating evidence suggests significant consequences for astrocytes associated with drug abuse. In male rats, self-administration and abstinence from cocaine leads to reductions in structural features and synaptic colocalization of nucleus accumbens astrocytes, while similar effects are not observed in female rats. These results indicate striking and sexually dimorphic effects of abstinence on astrocytes.

Summary: Extracellular vesicles (EVs) play significant roles as intracellular mediators, disease biomarkers, and therapeutic agents. Superparamagnetic iron oxide (SPIO) nanoparticles have been shown to improve the targeting ability of EVs. In this study, ultrasound sonication was used to load ultrasmall SPIO (USPIO) nanoparticles onto EVs derived from induced forebrain neural progenitor cortical organoids (iNPCo). The labeled EVs exhibited higher MRI contrast in agarose gel phantoms.

Summary: Recent advances in high-resolution microscopy have enabled scientists to study brain connectivity and predict changes in neural fiber morphology over time using a novel framework called NeuRegenerate. This framework incorporates a deep-learning network called neuReGANerator, which uses a cycle-consistent generative adversarial network (GAN) to translate features of neuronal structures across age-timepoints. The framework also includes visualization tools, such as neuroCompare and neuroMorph, to visualize the differences and transformations in neural projections. The framework is specifically designed for wide-field microscopy volumes and has been demonstrated in the study of cholinergic system changes in mouse brains.
