Diagnosis of a sublaryngeal abscess in a Japanese Black calf using computed tomography.

A 76-day-old Japanese Black calf presented with severe stridor, resenting palpation of the laryngeal region. Endoscopic examination revealed an expansile process restricting the esophageal and tracheal lumina caudal to the arytenoid cartilage, hyperemia and edema of the pharyngeal mucosa, right arytenoid cartilage swelling and displacement, and marked airway obstruction. The absence of an endotracheal wall abnormality impeded a definitive diagnosis.

phenol A Inhibits Cell Proliferation and Reduces the Motile Potential of Murine LM8 Osteosarcoma Cells.

Aim: The aim of this study was to examine the effect of bisphenol A (BPA) on the proliferation and motility potential of murine LM8 osteosarcoma cells.

Materials And Methods: LM8 cells were treated for 3 days with or without 80 μM BPA. The effect of BPA on cell proliferation was determined by DNA measurement in the cultures and 5-bromo-2'-deoxyuridine (BrdU) incorporation study.

Caries prevalence associated with Streptococcus mutans and Streptococcus sobrinus in Japanese schoolchildren.

Background: Streptococcus mutans and Streptococcus sobrinus are known to be associated with dental caries in humans.

Aim: We used a polymerase chain reaction method to detect S. mutans and S.

Nitric oxide-cGMP signaling regulates axonal elongation during optic nerve regeneration in the goldfish in vitro and in vivo.

Nitric oxide (NO) signaling results in both neurotoxic and neuroprotective effects in CNS and PNS neurons, respectively, after nerve lesioning. We investigated the role of NO signaling on optic nerve regeneration in the goldfish (Carassius auratus). NADPH diaphorase staining revealed that nitric oxide synthase (NOS) activity was up-regulated primarily in the retinal ganglion cells (RGCs) 5-40 days after axotomy.

Combination of monocyte-derived dendritic cells and activated T cells which express CD40 ligand: a new approach to cancer immunotherapy.

Interactions between dendritic cells (DCs) and activated T cells are critically important for the establishment of an effective immune response. To develop the basis for a new DC-based cancer vaccine, we investigated cell-to-cell interactions between human monocyte-derived DCs and autologous T cells that are activated to express the CD40 ligand (CD40L). Peripheral blood monocytes were cultured in the presence of granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 4 (IL-4) to induce differentiation of DCs.

Transgenic calmodulin-dependent protein kinase II activation: dose-dependent effects on synaptic plasticity, learning, and memory.

Genetic disruption of calmodulin-dependent protein kinase II (CaMKII) function alters hippocampal synaptic plasticity and memory in mice. We used transgenic mice carrying a tetracycline-regulated, calcium-independent form of CaMKII (CaMKII-Asp286) to investigate the role of CaMKII activation on synaptic plasticity and behavior. Mice expressing low levels of a CaMKII-Asp286 transgene have facilitated low-frequency (5 Hz)-induced long-term potentiation (LTP), whereas mice with high levels of transgene expression have a deficit in this form of plasticity.
