Article Synopsis
- The study introduces IMplicit UNrolled NEtworks (IMUNNE) as a new training strategy for dynamic MRI reconstruction, addressing issues of long training times and high GPU memory usage.
- IMUNNE frames the MRI reconstruction as an implicit fixed-point equation and uses a gradient approximation method, allowing it to work efficiently with deep learning models.
- Results show that IMUNNE improves image quality and significantly decreases training and inference times compared to existing methods, making it a promising solution for efficient cine MRI imaging.
We measured serum levels of brain-derived neurotrophic factor (BDNF) in 25 elderly women in 23 men-patients with chronic brain ischemia (CBI), and in 26 gender and age matched healthy controls. The serum levels of BDNF were significantly lower in patients with CBI as compared to healthy controls. The serum levels of BDNF were also lower in men with CBI (7815,14 x 10 ng/ml) in comparison to women-patients (8466,05 x 10 ng/ml).

Women with CBI had higher level of psychosocial stress than men. The results demonstrate the predomination of extrapunitive frustration reactions among women.
