More than 40 human diseases, mainly diseases affecting the central nervous system, are caused by the expansion of unstable nucleotide repeats. Repeats of sequences like (CAG) present in different genes can be responsible for various diseases of the central nervous system. An expanded hexanucleotide repeat (GGGGCC) in the C9ORF72 gene has been characterized as the most frequent genetic cause of amyotrophic lateral sclerosis and frontotemporal lobar dementia. In this study, we performed a genome-wide analysis in the human genome and identified 74 genes containing this precise hexanucleotide repeat, with a preference for a location in exon 1 or intron 1, similar to the C9ORF72 gene. A total of 36 of these 74 genes may be of interest as candidates in neurodevelopmental or neurodegenerative diseases, based on their function.

Lipid droplets (LDs), serving as the convergence point of energy metabolism and multiple signaling pathways, have garnered increasing attention in recent years. Different cell types within the central nervous system (CNS) can regulate energy metabolism to generate or degrade LDs in response to diverse pathological stimuli. This article provides a comprehensive review on the composition of LDs in CNS, their generation and degradation processes, their interaction mechanisms with mitochondria, the distribution among different cell types, and the roles played by these cells-particularly microglia and astrocytes-in various prevalent neurological disorders.

Objective: Autism spectrum disorder (ASD) is characterized by high rates of comorbidity with other mental disorders, including anxiety disorders and obsessive-compulsive disorder. Beyond a mere concept of comorbidity, recent literature is speculating the existence of a neurodevelopmental nature of such mental disorders. The aim of the study is to investigate the distribution of social-phobic, obsessive-compulsive and panic-agoraphobic traits within a sample of individuals with ASD, social anxiety disorder (SAD), obsessive-compulsive disorder (OCD) and panic disorder (PD).

Osteoporotic vertebral compression fractures (OVCFs) can be painful. Percutaneous kyphoplasty (PKP) aims at strengthening the vertebra and reducing pain, but efficacy can vary among patients. The purpose of this study was to establish a risk prediction model for pain relief following PKP in patients with OVCF.

Background: Effective connectivity (EC) analysis provides valuable insights into the directionality of neural interactions, crucial for understanding the mechanisms underlying cognitive and emotional regulation in depressive and anxiety disorders. This study examined EC within key neural networks during working memory (WM) and emotional regulation (ER) tasks in young adults, both healthy and seeking help from mental health professionals for emotional distress.
Methods: Dynamic Causal Modeling (DCM) was employed to analyze EC in two independent samples (n=97 and n=94).
Upregulation of olfactory-related neuropeptide transcripts in male Macrobrachium rosenbergii in correlation to pheromone perception from molting females.

Our previous studies revealed a mating attractant or possibly a pheromone released from molting reproductive mature female prawns, Macrobrachium rosenbergii, stimulates the expression of insulin-like androgenic gland hormones in a co-culture system. The released attractant is perceived by olfactory receptors with setae located on the short lateral antennules (slAn), which connect to the olfactory neuropil in the central nervous system (CNS) of male prawns. This neural signaling propagating through the CNS is mediated by at least four neuropeptides, namely neuropeptide F (NPF), short NPF (sNPF), tachykinin (TK), and allatostatin-A (ATS-A) whose transcripts have been detected in the present study.
