Evaluation of shoseiryuto for seasonal allergic rhinitis, using an environmental challenge chamber.

Background: Complementary and alternative medicine, including Japanese traditional medicine (JTM), has been used for various allergic diseases, but the evidence is limited. Shoseiryuto (Xiao-Qing-Long-Tang), one of the representative JTM drugs, is frequently used to treat allergic rhinitis (AR). However, its efficacy for seasonal AR has not been fully established.

A case of feline temporal lobe epilepsy with hippocampal sclerosis and dentate gyrus malformation.

A two-months-old, male, mixed breed cat presented with epileptic seizures. The cat was diagnosed with drug-resistant epilepsy, and died at 3-years of age. No gross lesion was found at necropsy.

DNA Methylation and HPV-Associated Head and Neck Cancer.

Head and neck squamous cell carcinoma (HNSCC), especially oropharyngeal squamous cell carcinoma (OPSCC), has recently been found to be significantly associated with human papillomavirus (HPV) infection. The incidence of OPSCC has been increasing and surpassed the number of cervical cancer cases in the United States. Although HPV-associated OPSCC has a relatively better prognosis than HPV-negative cancer, approximately 20% of HPV-associated HNSCC patients show a poor prognosis or therapeutic response, and the molecular mechanism behind this outcome in the intermediate-risk group is yet to be elucidated.

Production of canine soluble CD40 ligand to induce maturation of monocyte derived dendritic cells for cancer immunotherapy.

CD40 ligand (CD40L) expressed by activated T cells is shown to induce maturation of immature dendritic cells (DCs) and this maturation is a vital part in DC based tumor immunotherapy. We constructed an expression vector by cloning the extracellular domain of canine CD40L fused to the signal sequence of canine IL-12p40. When PBMCs were incubated with canine granulocyte-macrophage (GM) -CSF and IL-4, expression of CD86 was significantly elevated, but the majority of cells displayed the morphology of immature DCs.

Effect of sera from seronegative myasthenia gravis patients on neuromuscular junctions.

About 85 % of patients with generalized myasthenia gravis (MG) have anti-nicotinic acetylcholine receptor (nAChR) antibodies in their sera (seropositive MG; SPMG). The other 15 % (seronegative MG; SNMG) are also considered to have antibody-mediated disease, but the nature of the antibodies in SNMG is not fully understood. We investigated the effect of sera from patients with MG on spontaneous muscle action potentials and acetylcholine (ACh)-induced potentials, and we examined the localization of epitopes recognized by SPMG sera or SNMG sera.
