Summary: Emerging data suggest that endocannabinoid signaling is crucial for habitual behavior formation, and inhibiting FAAH and MAGL disrupts habit formation while AM251 exposure affects response rates. Further studies are needed to clarify the role of CB1R signaling in habitual responding and the potential clinical utility of augmenting endocannabinoids.

Summary: The aim of this study is to determine the role of endocannabinoids, anandamide (AEA) and 2-arachidonolylglycerol (2-AG), in regulating mechanosensitivity of probable nociceptive neurons innervating the bladder - capsaicin-sensitive mucosal afferents. The results showed that AEA potentiated the mechanical response of mucosal afferents, while 2-AG inhibited their response. These findings have important implications for understanding the role of endocannabinoids in regulating bladder sensation and function.

Summary: The endocannabinoid system offers a promising avenue for therapeutic interventions, but the presence of cannabinoid receptors in various organs and tissues can complicate targeted treatments. Injuries to the central nervous system can induce neuroinflammation and potentially affect the immune system. Exploring immunomodulatory therapies provides a hopeful alternative in the face of challenges in traditional preventive treatments.

Summary: Epilepsy is a common neurological disorder worldwide. Recent studies have shown that the use of cannabinoids and activation of the endocannabinoid system (ECS) can be a therapeutic strategy for controlling epilepsy. However, there are controversial findings regarding the effects of ECS activation.

Summary: Endocannabinoids 2-arachidonoyl-glycerol and N-arachidonoyl-ethanolamine are lipids that regulate various physiological processes, including inflammation, and are being studied as potential anti-inflammatory agents. Human eosinophils and neutrophils have been found to metabolize 1-linoleoyl-glycerol (1-LG) and N-linoleoyl-ethanolamine (LEA) into novel endogenous 15-lipoxygenase metabolites 13-HODE-G and 13-HODE-EA, although the biological significance of these metabolites is not yet fully understood.

Summary: This paper summarizes the potential and limitations of cannabinoids as therapeutics for AD, focusing on recent pre-clinical and clinical evidence. AD is a detrimental brain disorder characterized by cognitive decline and neuronal deterioration, with current treatments effective only in the early stages. Emerging research shows promising effects of cannabinoids in reducing amyloid plaque deposition and stimulating hippocampal neurogenesis in AD rodent models.

Summary: Childhood absence epilepsy is often accompanied by neuropsychological comorbidities such as anxiety. This study found that the synthetic cannabinoid receptor agonist WIN 55,212-2 had strain-dependent effects on anxiety-like and motor behavior in rats with absence epilepsy. The study also revealed alterations in cerebral monoaminergic levels in these rats, suggesting a role of endocannabinoids and monoamines in the comorbidities.

Summary: Endocannabinoids play a crucial role in response to stress and regulating the release of glucocorticoids, potentially contributing to the development of post-traumatic-stress-disorder (PTSD). Research shows elevated levels of 2-AG in the CSF of PTSD-phenotype rats, inversely correlated with corticosterone levels, and reduced levels of endocannabinoids in the hippocampus and hypothalamus in the PTSD-phenotype group, indicating a potential mechanism for PTSD symptomology.

Summary: The research demonstrates that inserting 1L-hBN can slightly block the interlayer electron transfer from the WS2 layer to the MoS2 layer, while weakening the interlayer coupling effect by releasing quantum confinement and reducing efficient dielectric screening. This results in a blueshift of exciton binding energies in WS2/hBN/MoS2 heterostructures, while the quasi-particle bandgap remains unchanged.

Summary: This study investigates the effect of uniaxial strain on the electronic properties of alpha-Te nanotubes (NTs) using first-principles calculations. The results show that the atomic structure of alpha-Te NTs remains stable under +/- 10% strain, demonstrating good flexibility. Increasing strain leads to a decrease in the band gap, with armchair (5, 5) alpha-Te NTs experiencing a semiconductor-metal transition. The valence band maximum and conduction band minimum charge density affect the type of band gap in the NTs, and strain can significantly modulate the optical properties. Understanding the electronic and optical properties of alpha-Te NTs under strain modulation is important for future optoelectronic applications.

Summary: In this study, we enhanced the light absorption of layered PtSe2 by engineering the optical impedance and the attenuation of the PtSe2-based metal-insulator-metal absorber. For a monolayer PtSe2-based absorber, near-perfect absorption (99.95%) was achieved by compensating the impedance mismatch with a top patterned metal array, leading to 8.6 times enhancement of absorption in the visible spectra. Few-layer PtSe2-based absorbers showed broadband absorption, insensitive to incident angle and polarization, due to the modulation of the self-impedance of the PtSe2 layer. These findings improve the feasibility of PtSe2-based optoelectronic and photonic devices and provide insights for absorber design with hybrid 2D materials.

Summary: It is discovered that a large fraction of over-coordinated clusters fails to generate mid-gap states, which are probably caused by hypervalent bonding, a multi-centered covalent bond participated by delocalized lone-pair electrons. In practical applications, compatible dopants can be used to change the number of hypervalent bonds, thus controlling the number of mid-gap states and consequently the performance of PCM and OTS materials. These results reveal the origin of mid-gap states in chalcogenide glasses, enabling extensive control in the development of pioneering electrical switching materials.

Summary: This study investigates the structure and electronic characteristics of amorphous GeS using ab initio molecular dynamics simulations. The results reveal that amorphous GeS is mainly composed of Ge-S bonds, with Ge- and S-centered clusters predominantly in the form of octahedral structures in liquid GeS. During the amorphization process, most Ge-centered clusters become highly coordinated octahedrons or tetrahedrons, while S-centered clusters gradually deviate from the octahedral structure. These structural features result in a high switching voltage in amorphous GeS.

Summary: This study investigated the protective effects and mechanisms of human placenta derived mesenchymal stem cells (hPMSCs) transplantation in a rat model of hypoxic-ischemic encephalopathy (HIE). The results showed that hPMSCs transplantation reduced apoptosis and improved long-term neurological prognosis. Furthermore, the downregulation of Sema 3A/NRP-1 expression and activation of the PI3K/Akt/mTOR signaling pathway played a key role in the protective effects of hPMSCs.

Summary: This study evaluated electrophysiological discrimination of parametric somatosensory stimuli in healthy young adults to understand how the brain processes the duration of tactile information. The results showed that participants did not electrophysiologically discriminate between 100 and 115 ms, but they exhibited distinct electrophysiological responses when the deviant stimuli were 130, 145, and 160 ms. These findings contribute to a better understanding of tactile sensitivity in different clinical conditions.

Summary: The basolateral amygdaloid complex (BLA) is closely involved in the formation of emotional memories, including both aversive memory and contextual fear memory. Acute sleep deprivation (SD) disrupts the acquisition of tone-associated fear memory in juvenile rats, but has no significant effect on contextual fear memory. Slow network oscillation in the amygdala contributes to the formation of amygdala-dependent fear memory in relation to sleep.
