See related article, pages 67–71. Transient global amnesia (TGA) was generally believed to have a psychogenic, epileptic, or thromboembolic etiology until the frequent comorbidity with migraine and the common accompanying symptoms (headache and dizziness) pointed toward cortical spreading depression as a pathogenic suspect.1,2 More recently, based on evidence that Valsalva-like activities may r...

In this work, the thermal behavior of rice husk, sewage sludge, and their blends during combustion processes was investigated by means of thermogravimetric analysis (TGA), and the slagging characteristics were studied through X-ray fluorescence (XRF) and melting temperature. The effects of the proportion of rice husk and sewage sludge blends on the combustion process, ignition and burnout chara...

Coumarin belongs to the family of benzopyrone found to have lot of biologically important. The present investigation focused on the synthesis of four derivatives from 4-Hydroxy-chromen-2-one and characterized using spectral (FTIR, H and C-NMR), Thermal (TGA) and morphological studies (SEM).

glucose, as the major energy source in cellular metabolism, plays an important role in the natural growth of cells. herein, a simple, rapid and low-cost method for the glucose determination by utilizing glucose oxidase and cdte/thioglycolic acid (tga) quantum dots (qds) on a thin layer chromatography (tlc) plate has been described. the detection was based on the combination of the glucose enzym...

Transient global amnesia (TGA) is a disorder with reversible anterograde disturbance of explicit memory, frequently preceded by an emotionally or physically stressful event. By using magnetic resonance imaging (MRI) following an episode of TGA, small hippocampal lesions have been observed. Hence it has been postulated that the disorder is caused by the stress-related transient inhibition of mem...

A 55-year-old banker was brought to the hospital by his wife because of temporal disorientation and repetitive questioning that had started 2 h before. His past medical history included an episode of TGA 11 years previously. Evaluation took place 3 h after the beginning of the episode. The Mini-Mental State Examination was 22/30, with mistakes on temporal orientation and word recall; the Fronta...
