Early History of Amnesia.

Early History of Amnesia. Front Neurol Neurosci. 2019;44:64-74 Authors: Langer KG Abstract Memory and forgetfulness have been viewed since antiquity from perspectives of physical, emotional, and spiritual states of well-being, and conceptualized philosophically. Numerous discussions of memory loss, or case reports, existed, but a fundamental advance in conceptualization of memory loss as a pathological clinical phenomenon originated when Sauvages classified "amnesia" as a medical disorder, in 1763. Originally, amnesia was recognized as a weakening or dissolution of memory, according to a taxonomy that ascribed known causes to the disorder. Etiologic factors included neurological disorders of stroke, hemorrhage, and head injury, metabolic dysregulation, alcohol and substance abuse, toxicity, anoxia, and other acute or chronic (sometimes progressive) brain disorders. Clinical descriptions of amnesia appeared internationally in medical dictionaries and scientific encyclopedias in the early 19th century. The possibility that amnesia could be either idiopathic, or symptomatic of another illness, was proposed based on the wide range of recognized etiologies and associations. Debate ensued regarding the status of amnesia as an illness or a symptom, but regardless, amnesia was soon recognized as an independent disorder of memory, distinguishable from disorders of global intellect, or of consciousness, or of language. Distinctions of amnesia considered i...

In the present study, we report that wogonin nanoparticles (Wog np) protect Isoproterenol (ISO) induced Myocardial Infarction (MI) rats. Nanoparticles of sizes less than 200 nm with spherical shape were prepared using Polylactic-co-glycolic acid (PLGA) and Polyvinyl alcohol (PVA) respectively as polymer and stabilizer. Male Wistar rats were divided into 4 groups. Group 1 as a control group a...

Polyvinyl alcohol (PVA), sodium alginate (Alg) were adopted as building blocks to form BNH. Calcium ions was used as crosslink agent to construct BNH. The skin injury model of diabetic rats was successfully established, and the prepared hydrogel was applied to the wound. Animal experiments proved that BNH cou...

Min Sun A capillary column coated with nanostructured silver coating was fabricated for gas chromatography. The nanostructured silver coating, about 80–120 nm in thickness, was prepared as the stationary phase via silver mirror reaction, and was characterized by SEM and EDS. The column was evaluated using different types of model analytes, including n-alkanes, n-alcohols, benzenes, and Grob mixture. A baseline separation of ten n-alkanes on the silver column (15 m × 0.20 mm i.d.) was achieved within 3.5 min through the main hydrophobic mechanism. A mixture of six n-alcohols, or another mixture conta...

Authors: Lee YH, Jang HW, Park CH, An SM, Lee EK, Choi BM, Noh GJ Abstract BACKGROUND: The aim of intraoperative fluid therapy is to avoid both hypovolemia and hypervolemia; however, the patient's exact volume status is difficult to determine during surgery. Fluid optimization guided by stroke volume variation (SVV) has been widely used in patients undergoing major open abdominal surgery. The aim of this study was to evaluate the changes in plasma volume before and after surgery following SVV-guided fluid therapy. METHODS: Patients were randomly allocated into one of two groups according to the SVV criteria for...
