Substance P is a neuropeptide involved in the integration of pain, stress, and anxiety. We hypothesized that substance P is a measure of pain in bulls following electroejaculation. The specific objective was to compare vocalization and plasma concentrations of cortisol, progesterone, and substance P immunoreactivity in bulls following electroejaculation. Nine Angus bulls (501.9 Ϯ 14.3 kg) were used. Blood samples were collected at Ϫ60, Ϫ30, 0, 2, 10, 20, 30, 45, 60, 75, 90, 120 min relative to treatment. At Time 0, bulls were subject to electroejaculation, rectal probe insertion without electroejaculation, or no manipulation. Treatments were administered contemporaneously to three bulls. Treatments were repeated weekly until each bull had received each treatment in a 3 ϫ 3 Latin square design. More bulls (P ϭ 0.0147) in the electroejaculation group vocalized (5 of 9 bulls; 55.6%) when compared to controls (0 of 9 bulls; 0%). Mean plasma cortisol and progesterone concentration following electroejaculation in bulls were higher (P Ͻ 0.05) than concentrations in probed and control bulls through the 45 min sample. However, mean plasma substance P concentration following electroejaculation in bulls (77.2 Ϯ 17.2 pg/mL) was not different (P ϭ 0.6264) from probed (79.1 Ϯ 17.2 pg/mL) or control bulls (93.4 Ϯ 17.2 pg/mL). A significant increase in vocalization and plasma cortisol and progesterone concentrations in bulls following electroejaculation was likely owing to acute stress. However, the lack of a difference in plasma concentrations of substance P after electroejaculation was interpreted as a lack of pain associated with nociception.

The pig was moderately anemic, and its abdomen was greatly distended. A freely movable abdominal mass was detected during palpation and ultrasonographic examination of the abdomen. Examination of abdominal and thoracic radiographs revealed faint, ill-defined, linear and curvilinear mineralized opacities in the region of the mass and that the gastrointestinal tract was displaced craniodorsally. Results of radiographic examination suggested that the cause of distention was a single abdominal mass (possibly a neoplasm). Surgery was performed, and the mass, which was identified as the right ovary, was removed. The left ovary had a normal appearance, but it was also removed during surgery. The pig was administered a transfusion (314 mL of plasma and 296 mL of packed RBCs) before and during surgery. The mass, which accounted for approximately one-third of the pig's body weight, was identified histologically as an ovarian leiomyoma. Pigs can safely be administered a transfusion of RBCs and plasma. Ovarian tumors can be removed from Vietnamese potbellied pigs, which allows them to be used as pets or for reproduction when only 1 ovary is affected. Uterine masses in older sexually intact Vietnamese potbellied pigs are more common than are ovarian tumors; thus, complete ovariohysterectomy should be considered when the primary purpose of the pig is to serve as a pet.

One of the best-studied systems is silica synthesis, as occurs in diatoms and marine sponges. Various biological and synthetic polymers have been shown to template and catalyze silica formation from silicic acid precursors. Here, we describe the use of poly-L-lysine to promote the synthesis of silica in neutral, aqueous solution and when immobilized onto a silicon support structure under similar conditions. Either reagent jetting or conventional photolithography techniques can be used to pattern the templating polymer. Spots created by reagent jetting led to the creation of silica structures in the shape of a ring that may be a result of the spotting process. Photolithographically defined poly-L-lysine spots led to thin laminate structures after exposure to a dilute aqueous silicic acid solution. The laminate structures were nanostructured and highly interconnected. Photolithographic patterning of (3-aminopropyl)trimethoxysilane, a reagent that mimics the lysine functional group, led to similar silica coatings even though low-molecularweight materials do not rapidly promote silica synthesis in solution. This result highlights the importance of functional-group arrangement for templating and promoting the synthesis of inorganic materials. The described surface-patterning techniques offer a route to integrate conventional silicon-patterning technologies with biologically based material synthesis. Such combined fabrication techniques enable controlled assembly over multiple length scales and an approach to understanding interfacial silica synthesis, as occurs in natural systems.

Potomac horse fever was diagnosed based on polymerase chain reaction (PCR) analysis of whole blood and a high antibody titer to Neorickettsia risticii. The mare made a rapid clinical recovery following antibiotic therapy, but aborted 98 days later. Necropsy on the aborted fetus revealed lymphohistiocytic colitis, lymphadenitis, myocarditis, and hepatitis. The placenta was grossly and histologically normal. Formalin-fixed lymph node, thymus, liver, and colon taken from the aborted fetus were positive by PCR for N. risticii DNA. Potomac horse fever is a common disease in horses that may result in delayed abortion. The microscopic lesions in the fetus are characteristic, and the diagnosis can be confirmed by PCR on formalin-fixed tissues.
