Traditional ovariectomy techniques for heifers (e.g. colpotomy) have adverse effects ranging from hemorrhage to mortality. Electrosurgical bipolar vessel sealing devices offer a superior ligation of ovarian pedicle and associated structures. In ruminants, standing flank laparotomy has been used for abdominal visibility. We performed ovariectomy in 2 companion beef heifers via a unilateral flank approach, combined with electrosurgical ligation. Surgeries were performed in standing animals, under local anesthesia, with no observed short- or long-term adverse effects. This technique is worth considering for cases where the security of electrosurgical ligation combined with the accessibility of a flank laparotomy are desired. Additional research …

Anesthesia Of The Geriatric Equine, Reza Seddighi Dvm, Ms, Phd, Dip Acva, Cvma

Faculty Publications and Other Works -- Large Animal Clinical Sciences

Advancements in veterinary medicine have resulted in an increased number of geriatric horses being presented for medical or surgical procedures that require general anesthesia. Due to the physiological changes associated with aging and the likelihood of concurrent disease conditions, the geriatric equine is at an increased risk during anesthesia. The main physiological changes associated with aging, and their impact on anesthesia, are discussed in this review.

This article describes the rationale behind the use of systemically administered lidocaine as an analgesic. The analgesic efficacy of intravenously administered lidocaine is well documented by studies in human patients and laboratory animals. The mechanism by which systemically administered lidocaine produces analgesia is uncertain but is thought to include action at sodium, calcium, and potassium channels and the N-methyl-D-aspartate acid receptor. …

Expression Of G-Protein Inwardly Rectifying Potassium Channels (Girks) In Lung Cancer Cell Lines, Howard K. Plummer, Madhu S. Dhar, Maria Cekanova, Hildegard M. Schuller

Faculty Publications and Other Works -- Large Animal Clinical Sciences

Background

Previous data from our laboratory has indicated that there is a functional link between the β-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in human breast cancer cell lines. We wanted to determine if GIRK channels were expressed in lung cancers and if a similar link exists in lung cancer.

Methods

GIRK1-4 expression and levels were determined by reverse transcription polymerase chain reaction (RT-PCR) and real-time PCR. GIRK protein levels were determined by western blots and cell proliferation was determined by a 5-bromo-2'-deoxyuridine (BrdU) assay.

Results

GIRK1 mRNA was expressed in three of six small …
