Inflammatory pseudotumor of the nasopharynx is a rare diagnosis that is often misinterpreted as carcinoma or lymphoma. It has been referred to as a tumefactive fibroinflammatory lesion, idiopathic pseudotumor, and fibrosing inflammatory pseudotumor. We present a rare case of a 40-year-old African American female from Kenya with inflammatory pseudotumor of(More)
—A closely spaced dual-band notched UWB MIMO antenna is proposed in this paper. A traditional semi-circular monopole with ultra-wideband operation is chosen as an element of the proposed MIMO antenna. When two of the UWB monopoles are put together closely, the mutual coupling between them is apparently strong. To reduce the coupling between the antenna(More)
OBJECTIVE To investigate the etiological characteristics of human rotavirus (HRV), human calicivirus (HuCV), human astrovirus (HAstV) and human enteral adenovirus (HAdV) in Ningxia province during 2011. METHODS Stool specimen was collected from acute diarrhea case of Ningxia during 2011. HRV was detected by ELISA and serotype/genotype identified on those(More)
OBJECTIVE To analyze the genetic evolution and bacterial type changes of Yersinia enterocolitica in the Ningxia area between year 1984 and 2011. METHODS A total of 296 strains of Yersinia enterocolitica was collected from diarrhea patients, pig, rodents, sheep and dogs between year 1984 and 2011. The serotype, biotype, ail, ystA, ystB, yadA, virF and(More)
OBJECTIVE To investigate the distribution of virulent genes of Yersinia enterocolitica (Y. enterocolitica) in Ningxia Hui autonomous region and the characteristics of the molecular patterns of Y. enterocolitica. METHODS 283 strains of Y. enterocolitica were isolated in Ningxia Hui autonomous region between year 1997 and 2010. The genes ail, ystA, ystB,(More)
Rosai-Dorfman disease (RDD) is a rare disorder involving massive benign proliferation of histiocytes in the lymph nodes. The etiology is unknown and the disease usually presents as painless lymphadenopathy accompanied with fever, night sweats, and weight loss. Due to its rarity, the disease is still difficult to diagnose when associated with extranodal(More)
