a 35-year-old man was admitted because of a 2-year history of nasal obstrction, a nasopharyngeal mass, malaise, and massive cervical lymphadenopathy. nasal symptoms and nasopharygeal mass were due to rhinoscleroma that was confirmed by an incisional biopsy and culture. the patient underwent cervical lymph node biopsy and culture. the patient underwent cervical lymph node biopsy that revealed th...
A 10 month prospective study of all adults admitted to Waikato Hospital with community acquired pneumonia was performed to assess aetiology, mortality, hospital stay, and the value of a prognostic index based on that obtained from a British Thoracic Society study. The 92 patients in the survey had a mean age of 56 (range 13-97) years. A microbiological diagnosis was established in 72%; Streptoc...
Genetic alterations of 13q21 (PCDH 8,9,17, and 20) are frequently observed in multiple tumors, suggesting the presence of critical tumor suppressor genes (TSGs). Protocadherin20 (PCDH20), located at 13q21.2, belongs to the δ1-protocadherins, which constitutes one of the largest subgroup within the adherin superfamily. Frequent downregulation/silencing of PCDH20 was found in NPC cell lines using...
Current testing for COVID-19 relies on reverse-transcriptase polymerase chain reaction from a nasopharyngeal swab specimen. Saliva samples have advantages regarding ease and painlessness of collection, which does not require trained staff may allow self-sampling. We enrolled 776 persons at various field-testing sites collected pooled saliva samples. One hundred sixty two had positive RT-PCR, 61...
OBJECTIVE To determine the incidence of equine herpesvirus-1 (EHV-1) infection among Thoroughbreds residing on a farm on which the virus was known to be endemic. DESIGN Prospective cohort study. ANIMALS 10 nonpregnant mares, 8 stallions, 16 weanlings, 11 racehorses, and 30 pregnant mares and their foals born during the 2006 foaling season. PROCEDURES Blood and nasopharygeal swab samples w...
PURPOSE To compare the doses calculated by the Acuros XB (AXB) algorithm and analytical anisotropic algorithm (AAA) with experimentally measured data adjacent to and within heterogeneous medium using intensity modulated radiation therapy (IMRT) and RapidArc(®) (RA) volumetric arc therapy plans for nasopharygeal carcinoma (NPC). METHODS Two-dimensional dose distribution immediately adjacent to...
The reprogramming factor Krüppel-like factor 4 (Klf4), one of the Yamanaka's reprogramming factors, plays an essential role in reprogramming somatic cells into induced pluripotent stem cells (iPSCs). Klf4 is dysregulated and displays divergent functions in multiple malignancies, but the biological roles of Klf4 in nasopharyngeal carcinoma (NPC) remain unknown. The present study revealed that Kl...
