An agar medium with improved selection for Treponema hyodysenteriae was developed. Cultures of T. hyodysenteriae and T. innocens, feces from 11 clinically normal pigs, and colonic contents from 6 pigs with gross lesions consistent with swine dysentery were diluted in phosphate-buffered saline and plated on Trypticase soy agar (BBL Microbiology Systems, Cockeysville, Md.) with 5% citrated bovine...

Pure cultures of six pathogenic isolates of Treponema hyodysenteriae, the colonic mucosal scrapings of seven pigs with acute swine dysentery, and feces from seven unaffected pigs were diluted in phosphate-buffered saline and plated on Trypticase soy agar with 5% citrated bovine blood (TSA) and TSA with various levels of spectinomycin (TSA-S). The plates were incubated at 42 degrees C in a vente...

Phosphorylation of the microtubule-associated Tau protein plays a major role in the regulation of its activity of tubulin polymerization and/or stabilization of microtubule assembly. A dysregulation of the phosphorylation/dephosphorylation balance leading to the hyperphosphorylation of Tau proteins in neurons is thought to favor their aggregation into insoluble filaments. This in turn might und...

The effect on blood pressure of high (400 mg/day-S400) and moderate dose (200 mg/day-S200) spironolactone and chlorthalidone (100 mg/day-C100), given in a random double-blind manner was related to plasma renin activity and plasma volume in 38 essential hypertensives. The fall in pressure from a control of 154/103 mm Hg was essentially the same after four weeks of each drug--S400 deltaBP 24/13 m...

Considering economical reasons and attempting to reduce carbon foot print of concrete structures, there is increasing tendency toward use of high strength reinforcement in seismically active regions. ACI 318-19, Iranian steel rebars standard INSO 3132 and next edition of Iranian national building allow the use of high strength rebars in elements of ductile force resisting systems. Therefore it ...

Background: Restraint stress causes inflammation in nervous system that leads to emersion of neurodegenerative diseases. Spinach (Spinacia oleracea L.) contains different agents with antioxidant, antiapoptosis, and hepatoprotective properties. This study examined the effect of spinach hydroalcoholic extract (SHE) on TNF-α and IL-1β expression in hippocampus of male Wistar rats exposed to chroni...

During the last two decades endoscopic skull base surgery observed a continuous technical and technological development 3D endoscopy and ultra High Definition (HD) endoscopy have provided great advances in terms of visualisation and spatial resolution. Ultra-high definition (UHD) 4K systems, recently introduced in the clinical practice, will shape next steps forward especially in skull base sur...

Fecal material from pigs experimentally infected with Treponema hyodysenteriae was collected and inoculated on six different selective media to compare their abilities for recovery of T. hyodysenteriae. Additionally, various types of samples were compared to find the most appropriate for submitting material to laboratories. Isolation rates for T. hyodysenteriae were 89.7% on BJ medium, 88.3% on...
