Nocardiosis is a rare infection caused by gram-positive aerobic actinomycetes, which are common in soil. Inoculation occurs by inhaling agent fragments that cause localized or systemic suppurative lesions. The diagnosis is established based on isolation in cultural examinations.

Comparison of apical periodontitis repair in endodontic treatment with calcium hydroxide-dressing and aPDT.

This study evaluated the effect of antimicrobial photodynamic therapy (aPDT) on the endodontic treatment of apical periodontitis (AP). AP was induced in 48 premolars of 6 dogs. After biomechanical preparation, the teeth were divided into 4 groups: Calcium-Hydroxide (CH)/120d and CH/180d: root canals filled with CH-based dressing for 15 days before obturation; aPDT/120d and aPDT/180d: conditioning with phenothiazine photosensitizer (10 mg/mL) for 1 minute and irradiation with diode laser in the same session as obturation.

Evaluation of palm kernel meal and corn distillers grains in corn silage-based diets for lactating dairy cows.

The effects of increasing levels of solvent-extracted palm kernel meal (SPKM) and corn distillers dried grains (CDG) in corn silage-based diets on feed intake and milk production were examined in 2 experiments. In Experiment 1, 20 Holstein cows averaging 100 d in milk (DIM) (SD = 61.5) at the start of the experiment were utilized in an 11-wk randomized complete block design with 4 treatments in 5 blocks to study effects of increasing levels of SPKM in the diet.
