Summary: Systemic CB1R antagonism during cocaine-memory reconsolidation reduced drug context-induced cocaine-seeking behavior and inhibited cellular adaptations and synaptic physiology changes in the basolateral amygdala. These findings suggest that CB1R signaling modulates cellular and synaptic mechanisms in the BLA, potentially playing a crucial role in preventing relapse.

Summary: This study investigated the alterations in 5-HT signaling and functionality in BTBR mice and their contribution to abnormal behaviors. Results showed a reduced number of 5-HT neurons in the median raphe of BTBR mice and decreased responsiveness to the 5-HT1A receptor agonist buspirone. Additionally, blunted c-Fos responses in the BLA and Hipp regions of BTBR mice were associated with a lack of anxiety-like behavior.

Summary: The classic surfactant proteins have important roles in the lungs and brain. A novel surfactant protein, SP-G, is linked to inflammation in the lungs and is also present in the brain, particularly elevated after hemorrhage in premature infants and in conditions affecting cerebrospinal fluid. This study suggests that SP-G might play a role in the pathophysiology of Alzheimer's disease.

Summary: This study aimed to investigate the differential associations between fear extinction memory and basal amygdaloid nucleus (BA) synaptic dysfunction in nonpathologic aging and Alzheimer's disease (AD). The results showed that long-term extinction memory was impaired in older AD rats, and was associated with hyperexcitability in the BA and impaired long-term potentiation (LTP) compared to young WT rats. In contrast, long-term extinction memory was impaired in aged WT rats but not associated with BA hyperexcitability. Interestingly, middle-aged AD rats showed intact short-term extinction and BA long-term potentiation, suggesting a compensatory mechanism. These findings indicate that the associations between fear extinction memory and amygdala deficits differ in nonpathologic aging and AD.

Summary: Through the study of threat conditioning, extinction, and second-order threat conditioning in animal models, insights have been gained into the brain-based mechanisms of fear- and anxiety-related disorders and their treatment. The basolateral amygdala (BLA) has received much attention in these processes, and this review provides an overview of its role. Recent evidence suggests that the BLA serves as the core of a greater network of structures, including associative and sensory cortices, in these forms of learning. The BLA is regulated by inputs from the hippocampus and prefrontal cortex, as well as by neuromodulators such as norepinephrine and dopamine, which may contribute important learning signals to these processes. The sensory cortices may play a crucial role in the long-term storage of threat memories, and further research can explore their potential in the storage of extinction and second-order conditioning memories.

Summary: In this study, the Bacillus anthracis vaccine strain Sterne 34F2 was cultured to obtain a secretome with a high concentration of non-degraded PA(83), which was used as an antigen in a Complement Fixation Test (CFT) to monitor antibody production. The results showed that the PAS-based CFT and commercial ELISA kit yielded similar results in terms of specificity and sensitivity, and the Sterne 34F2 vaccine induced a strong antibody response to PA(83) in vaccinated rabbits.

Summary: Cancer is a highly fatal disease with increasing prevalence. While the development of modern chemotherapy, radiotherapy, targeted therapies, and immunotherapy has brought new hope in the treatment of cancer, these therapies are also associated with frequent and sometimes severe adverse events. Ascorbate, a potent antioxidant, has been historically reported to have anti-tumor properties, but its deleterious effects due to interactions with iron have raised questions. Recent evidence suggests that high-dose ascorbate, particularly in cell systems with a high mitotic index, can positively modulate oxidative stress-induced cell death through ferroptosis. Ascorbate may also serve as an adjuvant in various cancer therapies by promoting tumor cell death through reactive oxygen species generation and ferroptosis. Re-examining ascorbate in cancer treatment could lead to the development of novel and safe strategies for its application in human medicine.

Summary: Neuropeptides derived from precursor proteins play important roles in regulating various physiological and behavioral processes in animals. In this study, researchers discovered two novel neuropeptides, ArCRZ and ArLQ, in the starfish Asterias rubens. However, they were unable to generate antibodies to these neuropeptides, hindering their analysis of neuropeptide expression. As an alternative approach, they generated antibodies to peptides corresponding to the C-terminal region of the precursor proteins and successfully demonstrated their applicability using the neuropeptide asterotocin. Furthermore, the generated antibodies to the C-terminal region of the ArCRZ and ArLQ precursors revealed the distribution of these neuropeptides in A. rubens and provided a neuroanatomical framework for future investigations.

Summary: In this study, a mouse model of Alzheimer's disease (AD) was used to investigate the expression of PDIA3, an endoplasmic reticulum chaperone, in brain regions affected by AD pathology. The results showed an age-dependent increase in PDIA3 levels in AD mice, and a significant reduction in PDIA3 at an early age compared to non-AD mice. Immunohistochemistry analysis revealed a correlation between the levels of A beta and PDIA3 proteins in all brain regions analyzed. The findings suggest that altered PDIA3 levels may play a role in AD pathology and could be a potential therapeutic target.

Summary: We conducted a comprehensive literature review on intoxications and fatalities related to New Psychoactive Substances (NPS) during the COVID-19 pandemic. The pandemic led to changes in drug consumption patterns, with some drugs being consumed less and an increase in the use of NPS. Synthetic opioids, synthetic cannabinoids, and synthetic cathinones were the most commonly abused NPS classes, and the combined consumption of several NPS classes accounted for 30% of all cases. It is important to consider that the reported cases may be an underestimate due to the impact of the pandemic on forensic toxicology capabilities.
