Attitudes of German General Practitioners Toward eHealth Apps for Dementia Risk Reduction: Qualitative Interview Study.
JMIR Form Res
January 2025
Institute of Social Medicine, Occupational Health and Public Health, Leipzig University, Leipzig, Germany.
Background: eHealth interventions constitute a promising approach to disease prevention, particularly because of their ability to facilitate lifestyle changes. Although a rather recent development, eHealth interventions might be able to promote brain health and reduce dementia risk in older adults.
Objective: This study aimed to explore the perspective of general practitioners (GPs) on the potentials and barriers of eHealth interventions for brain health.
Prefrontal 5α-reductase 2 mediates male-specific acute stress response.

A key response to acute stress is the increased brain synthesis of the neurosteroid allopregnanolone (AP). Although the rate-limiting step of this reaction is catalyzed by 5α-reductase (5αR), the role of its two primary isoenzymes, 5αR1 and 5αR2, in stress reactivity remains unclear. Here, we found that acute stress led to increased levels of 5αR2, but not 5αR1, in the medial prefrontal cortex (mPFC) of male, but not female, rats.

Sci Adv

Department of Biochemistry, College of Life Science and Biotechnology, Brain Korea 21 Project, Yonsei University, Seoul 03722, Republic of Korea.
Until now, Hippo pathway-mediated nucleocytoplasmic translocation has been considered the primary mechanism by which yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) transcriptional coactivators regulate cell proliferation and differentiation via transcriptional enhanced associate domain (TEAD)-mediated target gene expression. In this study, however, we found that TAZ, but not YAP, is associated with the Golgi apparatus in macrophages activated via Toll-like receptor ligands during the resolution phase of inflammation. Golgi-associated TAZ enhanced vesicle trafficking and secretion of proinflammatory cytokines in M1 macrophage independent of the Hippo pathway.

JAMA Netw Open
January 2025
Translational Research Center for TBI and Stress Disorders, Veterans Affairs Boston Healthcare System, Boston, Massachusetts.
Importance: There has been a great deal of interest in mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) and their association with one another, yet their interaction and subsequent associations with long-term outcomes remain poorly understood.
Objective: To compare the long-term outcomes of mTBI that occurred in the context of psychological trauma (peritraumatic context) with mTBI that did not (nonperitraumatic context).
Design, Setting, And Participants: This cohort study of post-9/11 US veterans used data from the Translational Research Center for Traumatic Brain Injury and Stress Disorders (TRACTS) study at the Veterans Affairs Boston Healthcare System, which began in 2009; the current study utilized data from baseline TRACTS visits conducted between 2009 and 2024.
Astrocytes in Primary Familial Brain Calcification (PFBC): Emphasis on the Importance of Induced Pluripotent Stem Cell-Derived Human Astrocyte Models.

Department of Biological Sciences, Middle East Technical University, Ankara, Türkiye.
Primary familial brain calcification (PFBC) is a rare, progressive central nervous system (CNS) disorder without a cure, and the current treatment methodologies primarily aim to relieve neurological and psychiatric symptoms of the patients. The disease is characterized by abnormal bilateral calcifications in the brain, however, our mechanistic understanding of the biology of the disease is still limited. Determining the roles of the specific cell types and molecular mechanisms involved in the pathophysiological processes of the disease is of great importance for the development of novel and effective treatment methodologies.
