Background: In schizophrenia (SZ), impairments in cognitive functions, such as working memory, have been associated with alterations in certain types of inhibitory neurons that utilize the neurotransmitter -aminobutyric acid (GABA) in the dorsolateral prefrontal cortex (DLPFC). For example, GABA neurons that express parvalbumin (PV) or somatostatin (SST) have more prominent gene expression alterations than those that express vasoactive intestinal peptide (VIP). In bipolar disorder (BD) and major depression (MD), which exhibit similar, but less severe, cognitive impairments than SZ, alterations of transcript levels in GABA neurons have also been reported.

Article Synopsis
  • The study investigates the relationship between obesity and schizophrenia by comparing brain structures in patients with schizophrenia who have different waist circumferences.
  • It finds that patients with higher waist circumference exhibit lower white matter integrity and cortical thickness in specific brain regions compared to healthy controls, while those with lower waist circumference also show reduced white matter integrity.
  • Cognitive performance was notably worse in the patients with higher waist circumference, who also had higher triglyceride levels, highlighting potential neurocognitive deficits related to excessive abdominal obesity in schizophrenia.

Article Synopsis
  • The study talks about how people with schizophrenia have problems with visuospatial working memory, which is the ability to remember visual information and how things relate to each other in space.
  • Researchers found that certain brain cells called PV and SST neurons don't work as well in people with schizophrenia, and this affects other brain cells called pyramidal neurons.
  • The scientists measured specific transcripts (kind of like instructions for how cells work) in different brain areas and found that people with schizophrenia had lower levels, which could cause the memory problems they experience.

Background: Patients with cerebrovascular disorders (CVDs) tend to exhibit impulsive behaviour without controlling their movements, leading to difficulty in performing activities of daily living and an increased risk of accidents. This hastiness, termed 'pacing impairment', has been studied but is not fully understood.

Objective: To experimentally examine the kinetic features of pacing impairment by focusing on changes in speed and investigating neuropsychological substrates.

Introduction: The dynamics of large-scale networks, which are known as distributed sets of functionally synchronized brain regions and include the visual network (VIN), somatomotor network (SMN), dorsal attention network (DAN), salience network (SAN), limbic network (LIN), frontoparietal network (FPN), and default mode network (DMN), play important roles in emotional and cognitive processes in humans. Although disruptions in these large-scale networks are considered critical for the pathophysiological mechanisms of psychiatric disorders, their role in psychiatric disorders remains unknown. We aimed to elucidate the aberrant dynamics across large-scale networks in patients with schizophrenia (SZ) and mood disorders.

Although uncovered self-expandable metal stents (SEMSs) possess certain advantages such as averting cystic duct obstruction and stent migration, they are susceptible to ingrowth occlusion. The combination of the double bare stent (DBS) and endobiliary radiofrequency ablation (RFA) may reduce ingrowth. Hence, this study aimed to examine the utility of this method for the treatment of unresectable malignant distal biliary obstruction (MDBO).
