Insights into risk factors and outcomes of post-stroke seizures in Saudi Arabia: a multicenter analysis.

Post-stroke seizures present a global challenge, yet its frequency and factors associated with its incidence are poorly documented, particularly in the Middle East. Thus, this study aims to investigate post-stroke seizure frequency and stroke-associated factors among ischemic stroke patients in Saudi Arabia, addressing demographic, clinical, and comorbid aspects to improve prognosis, diagnosis, prevention, and management. A multicenter, cohort observational study included eligible ischemic stroke patients who were categorized into those who developed seizures after injury and those who did not.

Acoustic shock wave-induced superheating-assisted dynamic recrystallization - a case study of D-tartaric acid.

Co-precipitation synthesis of highly pure and Mg-doped CdO nanoparticles: from rod to sphere shapes.

This study reports a facile approach for examining surface morphology transitions in semiconductor nanoparticles (NPs), with a focus on pristine and magnesium-doped cadmium oxide NPs. Mg-doped CdO NPs are synthesized co-precipitation, and their composition, structure, and elemental distribution are analyzed through X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Raman spectra, and X-ray photoelectron spectroscopy (XPS), along with optical characterization and impedance analysis. Doping with Mg changes the morphology from rod-like to quasi-spherical, reduces the crystallite size, and impacts their structural and functional properties.

Acoustic Shock Wave-Induced Amorphous to Crystalline Phase Transitions of LiSO─Raman Spectroscopic and Thermal Calorimetric Approach.

In this context, we have reexamined the acoustical shock wave-induced amorphous-glassy-crystalline-amorphous phase transitions in the LiSO sample under 0, 1, 2, and 3 shocked conditions by implementing the detailed Raman spectroscopic approach. The recorded Raman spectroscopic data clearly reveal that the transition from the amorphous-glassy-crystalline state occurs because of a significant reduction of the translational disorder of lithium cations, particularly [Li (2)] ions wherein a slight reduction of the librational disorder of SO anions takes place, whereas the crystalline to amorphous transition occurs only at the third shocked condition because of the librational disorder of SO anions. The double degenerate υ and υ Raman modes provide a clear indication of the occurrence of the librational disorder of SO anions at the third shocked condition.
