“…The lack of a measurable neurological deficit beyond 12 days may be due to the sensitivity of the scoring system. Alternatively, methods such as a digital video-based tracking system for automatically tracking the spontaneous locomotor behavior of pigs 29 could provide a more sensitive assessment and possibly detect a significant difference between permanent and sham-operated groups beyond 12 days. Alternatively, it is possible that the miniature pig has an ability to spontaneous recovery over time.…”

Background and Purpose-Lacunar infarction accounts for 25% of ischemic strokes, but the pathological characteristics have not been investigated systematically. A new experimental model of lacunar infarction in the miniature pig was developed to investigate the pathophysiological changes in the corticospinal tract from the acute to chronic phases. Methods-Thirty-five miniature pigs underwent transcranial surgery for permanent anterior choroidal artery occlusion.Animals recovered for 24 hours (nϭ7), 2 (nϭ5), 3 (nϭ2), 4 (nϭ2), 6 (nϭ1), 7 (nϭ7), 8 (nϭ2), and 9 days (nϭ1), 2 weeks (nϭ2), 4 weeks (nϭ3), and more than 4 weeks (nϭ3). Neurology, electrophysiology, histology, and MRI were performed. Seven additional miniature pigs underwent transient anterior choroidal artery occlusion to study muscle motor-evoked potentials and evaluate corticospinal tract function during transient anterior choroidal artery occlusion. Results-The protocol had a 91.4% success rate in induction of internal capsule infarction 286Ϯ153 mm 3 (meanϮSD). Motor-evoked potentials revealed the presence of penumbral tissue in the internal capsule after 6 to 15 minutes anterior choroidal artery occlusion. Total neurological deficit scores of 15.0 (95% CI, 13.5 to 16.4) and 3.4 (0.3 to 6.4) were recorded for permanent anterior choroidal artery occlusion and sham groups, respectively (PϽ0.001, maximum score 25) with motor deficit scores of 3.4 (95% CI, 2.9 to 4.0) and 0.0 (CI, 0.0 to 0.0), respectively (PϽ0.001, maximum score 9). Histology revealed that the internal capsule lesion expands gradually from acute to chronic phases. Conclusions-This

No exact and digital diagnostic methods for depression have been found. In this study, we prepared a 5-HT biosensor based on screen-printed electrode and applied it to a rat depression model caused by chronic unpredictable mild stress (CUMS). During CUMS, the blood 5-HT and the depression behavior of the depressed rats and the rats treated by antidepressants were recorded. The correlation coefficient of 5-HT was 0.9966 (0 -4 × 10 -6 M) on the sensor. Results demonstrated that 5-HT level of the depressed rats declined while the depression behavior was aggravated. Fluoxetine (20 mg/kg) and lentinan (10, 20 mg/kg) mildly elevated 5-HT level and slowly regulated the behavior. Mifepristone (20 mg/kg) and Rhizoma Coptidis water extract (10, 20, 100 mg/kg) quickly reversed 5-HT level and the depression behavior. This sensor can accurately test blood 5-HT and might be applied to rapid diagnosis for depression and evaluation of antidepressants effect.

“…Despite the recent advances in the field of automated video tracking of pigs in group housing (Lind et al, 2005;Ahrendt et al, 2011), the most suitable method to automatically identify individual animals remains RFID (Artmann, 1999;Eradus and Jansen, 1999;Ruiz-Garcia and Lunadei, 2011). Radio Frequency Identification is a collection of techniques for contactless transfer of data between a datacarrying device and a reader using (electro)magnetic fields (Finkenzeller, 2010).…”
