Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

Treatment with an inhibitor of glucose use via glucose transporters (GLUT) has been shown to attenuate experimental abdominal aortic aneurysm (AAA) development in mice. Vascular smooth muscle cell (VSMC) signaling seems to be essential for angiotensin II (Ang II)-induced AAA in mice. Accordingly, we have tested a hypothesis that VSMC silencing of the major GLUT, GLUT1, prevents AAA development and rupture in mice treated with Ang II plus β-aminopropionitrile.

Traumatic cerebrospinal fluid (CSF) leakage from skull base fractures increases the risk of bacterial meningitis, which is associated with a high mortality rate in adults, and commonly results in severe neurological outcomes. While most cases of CSF leakage occur within three months post-injury and generally resolve spontaneously, delayed-onset meningitis remains a challenging complication. Herein, we report a rare case of severe bacterial meningitis with an intraventricular abscess one year following a frontal skull base fracture, despite no CSF leak.

Animacy perception, the ability to discern living from non-living entities, is crucial for survival and social interaction, as it includes recognizing abstract concepts such as movement, purpose, and intentions. This process involves interpreting cues that may suggest the intentions or actions of others. It engages the temporal cortex (TC), particularly the superior temporal sulcus (STS) and the adjacent region of the inferior temporal cortex (ITC), as well as the dorsomedial prefrontal cortex (dmPFC).

Background: MECP2 Duplication Syndrome, also known as X-linked intellectual developmental disorder Lubs type (MRXSL; MIM: 300260), is a neurodevelopmental disorder caused by copy number gains spanning MECP2. Despite varying genomic rearrangement structures, including duplications and triplications, and a wide range of duplication sizes, no clear correlation exists between DNA rearrangement and clinical features. We had previously demonstrated that up to 38% of MRXSL families are characterized by complex genomic rearrangements (CGRs) of intermediate complexity (2 ≤ copy number variant breakpoints < 5), yet the impact of these genomic structures on regulation of gene expression and phenotypic manifestations have not been investigated.
