Evidence of foreign material, with an appearance consistent with endodontic sealer materials, was seen in 25 periapical granulomas, two cysts and one scar. Two periapical scars were seen, one had a history of apicectomy and amalgam root-end filling while the other was associated with extruded root
filling material.\n\nBy using defined clinical inclusion and exclusion criteria a predictable clinical diagnosis of a persistent periapical lesion due to endodontic origin can be reliably made. Periapical granulomas and Crenolanib in vivo cysts were the most common periapical lesions of endodontic origin associated with persistent periapical pathosis with the overall incidence of periapical cysts similar to previous studies. The presence of endodontic material in a high proportion of periapical lesions suggests a cause-effect association with the inference that clinicians should employ canal preparation techniques that limit apical extrusion of material.”
“Forty Dorper x Pelibuey ram lambs initially weighing 31.7 +/- 2.30 kg were stratified by BW and randomly assigned to treatments under a completely randomized design with a 2 x 2 factorial arrangement of treatments to evaluate effects of zilpaterol hydrochloride (ZH; 0 or Dinaciclib Cell Cycle inhibitor 10 mg/lamb daily) and soybean oil (SBO; 0 or 6%) on feedlot performance, carcass characteristics, and wholesale cut yield of ram lambs under heat stress conditions. After a 34-d feeding
period, all lambs were harvested. Climatic conditions were of moderate heat stress (average temperature 35.7 degrees C) for lambs during the study. Interactions ZH x SBO were not observed (P bigger than = 0.11) for any of the variables evaluated. During the first 17 d of experiment, ZH increased (P smaller than = 0.05) BW, ADG, and G: F without affecting feed intake (P = 0.40), but from d 18 to 34 and the entire 34-d feeding period,
feedlot performance was not affected (P = 0.18) by ZH. Also, ZH decreased KPH, dressing percent, LM area, LM pH at 24 h postmortem, and leg perimeter (P smaller than = 0.04). Renal fat (P = 0.03) decreased with ZH while other non-carcass components were not affected (P bigger than = 0.06) by Selleck Pinometostat ZH supplementation. Leg yield (P = 0.01) and plain loin (P = 0.04) decreased with ZH and yields of other wholesale cuts were not affected (P bigger than = 0.10) by ZH. Feedlot performance (P bigger than = 0.20) and wholesale cut yield (P bigger than = 0.21) were not affected by SBO. Additionally, dressing percentage decreased (P smaller than 0.01) with SBO while other carcass characteristics (P bigger than = 0.12) were not affected by SBO. In conclusion, inclusion of both ZH and SBO in feedlot finishing diets did not improve feedlot performance, carcass characteristics, or wholesale cut yield of hair-breed ram lambs under moderate heat stress. Feedlot performance responded only to ZH and only during the first 17 d of the feeding period.
