The new pulse sequence (PS) has been obtained on MRI tomography Ellipse, B=0,15 and Biospec 70/30, B=7 T. The new pulse images of the brain combine features of FLAIR and its sensitivity to magnetic field heterogeneity. We named its PS as the T2 Fluid Attenuation Gradient Echo (T2 FLAGE). The T2 FLAGE characteristics of tissue contrast as well as its efficacy in detection of ICH have been assessed in 57 patients with acute stroke and in 16 experimental rats. The analysis of tissue contrast of lesions and normal brain structure has revealed the greater visibility of T2 FLAGE images compared to FLAIR. At the same time, the images sensitivity of magnetic field heterogeneity is retained. The ROC-analysis has shown that T2 FLAGE images are more effective in differential diagnosis of stroke type compared to FLAIR.

Boosting the energy storage performance of BCZT-based capacitors by constructing a Schottky contact.

Multilayer thin films composed of dielectric BaCaZrTiO (BCZT) and oxygen-deficient BCZT (BCZT-OD) were fabricated on (001)-oriented NSTO substrates using the pulsed laser deposition (PLD) technique. Unlike conventional approaches to energy storage capacitors, which primarily focus on compositional or structural modifications, this study explored the influence of the layer sequence and periodicity. The interface between the NSTO substrate and the BCZT-OD layer forms a Schottky barrier, resulting in electric field redistribution across the sublayers of the BCZT/BCZT-OD//(1P) thin film.

Unlabelled: The R package CropPro is an open-access resource to classify archaeobotanical samples as products and by-products of different stages of the crop processing sequence for large-seeded cereal and pulse crops in south west Asia, Europe and other Mediterranean regions. It builds on ethnographic research and analysis conducted by Jones (Plants and ancient man: studies in palaeoethnobotany. Balkema, Rotterdam, pp 43-61, 1984), (J Archaeol Sci 14:311-323, 1987), (Circaea 6:91-96, 1990) and a modified method by Charles (Environ Archaeol 1:111-122, 1998).

Purpose: Two-shot γ-aminobutyric acid (GABA) difference editing techniques have been used widely to detect the GABA H4 resonance at 3.01 ppm. Here, we introduce a single-shot method for detecting the full GABA H2 resonance signal, which avoids contamination from the coedited M macromolecules.

Background: Aspirin has proved its efficacy in reducing the rate of preeclampsia in singleton pregnancy, however, there is discrepancy about the efficient dosage that should be used. While some societies recommend daily 75-81mg, others recommend higher dosage (160mg). This discrepancy is due to the lack of randomized controlled studies that compare these two dosages.

Background: The levels of conductivity in the extracellular and intracellular space of the brain are still unknown, especially in the brains of Alzheimer's disease (AD) patients. The objectives of this study were to investigate how the extra-neurite conductivity (EC) and intra-neurite conductivity (IC) were reflected in AD patients compared with elderly CN people and patients with amnestic mild cognitive impairment (MCI) and to evaluate the association between EC and cognitive decline.
Method: A total of 66 patients were included including 20 AD patients, 25 amnestic mild cognitive impairment (MCI) patients, and 21 cognitively normal (CN) old people.
