Introduction: Sex as a biological variable (SABV) may help to account for the differential development and expression of post-traumatic stress disorder (PTSD) symptoms among trauma-exposed males and females. Here, we investigate the impact of SABV on PTSD-related neural alterations in resting-state functional connectivity (rsFC) within three core intrinsic connectivity networks (ICNs): the salience network (SN), central executive network (CEN), and default mode network (DMN).

Methods: Using an independent component analysis (ICA), we compared rsFC of the SN, CEN, and DMN between males and females, with and without PTSD (n = 47 females with PTSD, n = 34 males with PTSD, n = 36 healthy control females, n = 20 healthy control males) via full factorial ANCOVAs.

Introduction: Real-time fMRI-based neurofeedback (rt-fMRI-NFB) is a non-invasive technology that enables individuals to self-regulate brain activity linked to neuropsychiatric symptoms, including those associated with post-traumatic stress disorder (PTSD). Selecting the target brain region for neurofeedback-mediated regulation is primarily informed by the neurobiological characteristics of the participant population. There is a strong link between PTSD symptoms and multiple functional disruptions in the brain, including hyperactivity within both the amygdala and posterior cingulate cortex (PCC) during trauma-related processing.

Article Synopsis
  • Alterations in brain networks, particularly the default mode and salience networks, are linked to PTSD symptoms, with the posterior cingulate cortex (PCC) playing a key role in regulating these changes.
  • A study involved 14 PTSD patients and 15 healthy controls to measure PCC connectivity during neurofeedback sessions, comparing conditions where participants either regulated or observed PCC activity.
  • Findings reveal that, unlike healthy controls, the PTSD group exhibited stronger PCC connectivity with critical brain areas during regulation, suggesting these connections may underlie symptom improvements in PTSD patients.

Converging evidence has suggested that disturbances in monetary reward processing may subserve the shared biosignature between major depressive disorder (MDD) and obesity. However, there remains a paucity of studies that have evaluated the deficits in specific subcomponents of reward functioning in populations with MDD and obesity comorbidity. We evaluated the association between effort-expenditure for monetary reward and neural activation in regions associated with reward-based decision making (i.

Introduction: Bipolar disorder (BD) is characterized by a pro-inflammatory biotype, and is a major cause of cardiovascular disease (CVD), consequently causing elevated rates of morbidity and mortality among individuals with BD.

Methods: The present study is based on a 12-week clinical trial assessing the antidepressant effects of adjunctive infliximab treatment in BD. Generalized estimating equation (GEE) models were used to evaluate CVD risk in people with BD following adjunctive infliximab treatment at baseline and week 12.

Background: Candidate gene and genome-wide association studies have identified hundreds of asthma risk loci. The majority of associated variants, however, are not known to have any biological function and are believed to represent markers rather than true causative mutations. We hypothesized that many of these associated markers are in linkage disequilibrium (LD) with the elusive causative variants.

Background: Renal thrombotic microangiopathy (TMA) is occasionally seen in biopsies with pauci-immune necrotizing crescentic glomerulonephritis (PCGN). Recent study indicated that the complement activation is more prominent in the ANCA-negative glomerulonephritis.

Case Presentation: We report a case of concurrent TMA and PCGN without ANCA positivity.

Purpose: Transforming growth factor-beta1 plays a central role in colonic repair. We examined the temporal effect of vector-mediated transfer of transforming growth factor-beta1 on colonic anastomotic healing.

Methods: Male Sprague-Dawley rats (n = 24) underwent transection of the distal colon and single-layer anastomosis.
