Purpose: The relationship between the physical parameters of pulsed beams and the FLASH effect remains largely unexplored. Our research aimed to investigate systematically the beam requirements necessary for pulsed electron FLASH radiation therapy, which is characterized by high average dose rates (DR) and large doses-per-pulse (DPP).
Methods And Materials: The abdominal cavity of tumor-free C57BL/6 mice was irradiated with a pulsed electron beam at 17 Gy, generated by a prototype electron linear accelerator.

Unlabelled: Electroencephalography-based (EEG) microstate analysis is a promising and widely studied method in which spontaneous cerebral activity is segmented into sub second level quasi-stable states and analyzed. Currently it is being widely explored due to increasing evidence of the association of microstates with cognitive functioning and large-scale brain networks identified by functional magnetic resonance imaging (fMRI). In our study using the four archetypal microstates (A, B, C and D), we investigated the changes in resting state EEG microstate dynamics in persons with temporal lobe epilepsy (TLE) and idiopathic generalized epilepsy (IGE) compared to healthy controls (HC).

Microstate analysis is a spatiotemporal method where instantaneous scalp potential topography represents the current state of the brain. The temporal evolution of these scalp topographies gives an understanding of quasi-stable periods of long-range coherence between distant electrodes, reflecting functional coordination within large-scale cortical networks. It has been proven potential in identification and characterization of neurophysiological indicators associated with neuropsychiatric conditions.

Background: In the COVID era, medical education has been hit hard. Paradoxically, the need for health professionals has increased. Online methods are being widely used, but its efficacy is rarely measured.
View Article and Find Full Text PDFTwist1, a key transcription factor regulating epithelial-mesenchymal transition and cancer metastasis, is highly expressed in invasive cancers in contrast to the loss of BTG2 expression. Based on our observation that forced expression of BTG2 downregulated Twist1 protein expression without altering mRNA level, we investigated molecular mechanisms of the BTG2-inhibited Twist1 translation in the triple negative breast cancer (TNBC) cells and in vivo BTG2-knockout (KO) mice and human breast cancer tissues. (1) C-terminal domain of Twist1 and Box B of BTG2 interacted with each other, which abrogated Twist1 activity.
