Endobronchial lipomatous polyp is a rare nonmalignant tumor of the lung. It comprises 5% of the benign lung tumor, with the majority of benign tumors being hamartoma. Lipomatous polyp often leads to endobronchial lesion, associated with postobstructive pneumonia, hemoptysis, and atelectasis. We hereby present a case and discussion of an elderly man with endobronchial lipomatous polyp, presentin...

Pseudomonas putida CA-3 accumulates polyphosphate (polyP) and medium-chain-length polyhydroxyalkanoate (mclPHA) concurrently under nitrogen limitation. Five other mclPHA-accumulating Pseudomonas strains are capable of simultaneous polyP and mclPHA biosynthesis. It appears that polyP is not the rate-limiting step for mclPHA accumulation in these Pseudomonas strains.

introduction: hyperplastic pulpitis (pulp polyp)tissues contains cells with stem cell properties similar to that of the dental pulp stem cells (dpscs). it has also been shown that cd146 enrichment can homogenize the cultures of dpscs and enhance the colony forming potentials of their cultures. this study determines whether cd146 enrichment can help purifying the stem cells from heterogeneous cu...

Although CD4(+) T cells are recognized to play an important role in the inflammatory response of nasal polyps (NPs), the biological functions of CD8(+) T cells in polypogenesis remain unclear. In this study, we analyzed cell markers, cytokine expression and transcription factors in IL-21-expressing CD8(+) T cells in polyp tissues of NP patients. The results showed that the majority of IL-21-pro...

OBJECTIVES AND METHODS To confirm the local production of IgE antibody from the nasal polyp tissue, and to evaluate the difference between atopics and non-atopics, nasal polyp tissues were taken from both 10 atopic and 10 non-atopic subjects. The tissue total IgE (tlgE) level was measured by enzyme-linked immunosorbent assay (ELISA) and serum tlgE level by radio-immunoassay. The tissue albumin ...

Short-chain polyphosphate (polyP) is released from platelets upon platelet activation, but it is not clear if it contributes to thrombosis. PolyP has increased propensity to clot blood with increased polymer length and when localized onto particles, but it is unknown whether spatial localization of short-chain polyP can accelerate clotting of flowing blood. Here, numerical simulations predicted...

Computed tomography colonoscopy (CTC) is an emerging alternative to conventional colonoscopy for colorectal cancer screening. A series of computer assisted diagnosis (CAD) techniques have been developed for use in CTC. Although high levels of accuracy for polyp detection have been reported, the problem of excessive false positive detections still warrants attention. We present a CAD-CTC techniq...

Pseudoinvasion or pseudocarcinomatous invasion in an adenomatous polyp of the colon can be unfamiliar to an endoscopist. Pseudoinvasion in an adenomatous polyp represents prolapse of the adenomatous epithelium into its stalk. In most cases its morphology does not differ from of general adenomatous polyps, but in some cases it can morphologically mimic a malignant polyp with submucosal invasion ...

A solitary Peutz-Jeghers polyp is defined as a unique polyp occurring without associated mucocutaneous pigmentation or a family history of Peutz-Jeghers syndrome. Gastric solitary localization is a rare event, with only eight reported cases to date. We report herein the case of a 43-year old woman who presented with upper gastrointestinal bleeding, severe anemia, weight loss and asthenia. Endos...

lon polypectomy. A colonoscopic examination had been carried out in another hospital several days earlier due to hematochezia and a polyp had been found in the sigmoid colon. The 1.5-cm, pedunculated polyp (●" Fig. 1) had a slight bulge in the stalk, and there was a mucosal bridge at the attachment to the intestinal wall, mimicking a submucosal tumor. The polyp was resected at the midportion of...
