This difference was not significant learn more (p = 0.60). Laboratory parameters and clinical data were comparable between groups. TNF levels were lower in children receiving PTX.
Conclusions: The small sample size does not permit definitive conclusions, but the mortality rate was unexpectedly high in the PTX group.”
“Simultaneous occurrence of squamous cell carcinoma in situ (SIS) and adenocarcinoma in situ (AIS) is very rare in Japan.
The author reports a rare case of coexistence of SIS and AIS in a young Japanese woman. A 36-year-old Japanese woman complained of abnormal uterine bleeding, and consulted to our hospital. Colposcopic examination revealed
irregular lesions in the cervix, and a biopsy showed simultaneous SIS and AIS. Conization was performed. The SIS corresponded to cervical intraepithelial neoplasm3, HGSIL, or carcinoma in situ, and AIS was typical
AIS. The SIS showed in situ atypical cells without stratification and polarity. The AIS showed tubular or cribriform apparent AIS of mixed endocervical and intestinal type. There was adequate structural and cytological atypia regarded as malignant in both lesions. Most of the areas of SIS and AIS were separated but the two were occasionally seen to merge when involving the glands. Immunohistochemically, both elements were positive for cytokeratins, p53 protein, CEA, and CA125. The Ki-67 labeling was 82% in the SIS and 78% this website in the AIS.
The author reported a Japanese case of combined SIS and AIS, so far infrequently reported in Japanese woman.”
“Background: Implantations of metallic biomedical devices into bodies are increasing. The elution of Ni ions from these devices can lead to
metal allergies. However, the molecular mechanisms of the elution have not been fully examined. Furthermore, it is not clear whether infection and inflammation affect the corrosion of metals.
Objective: We examined whether the elution of Ni from metal wires and plates was enhanced by inflammation in vivo and in vitro.
Methods: A Ni or SUS316L LY3023414 inhibitor wire was implanted subcutaneously in the dorsum of mice. Lipopolysaccharide (LPS) was injected at the site immediately following the implantation. After 8, 24, and 72 h, the tissue around the wire was excised. RAW 264 cells were seeded on a Ni plate and incubated for 24 h in medium containing LPS. The amount of Ni in the tissue or conditioned medium was determined fluorometrically.
Results: The release of Ni ions from the wire was significantly increased from 8 to 72 h, and further increased by LPS. LPS also enhanced the release of Ni ions by the cells, but only when they were attached to the Ni plate. Chloroquine, bafilomycin A(1) and amiloride markedly inhibited the effects of LPS.
Conclusion: The activation of inflammatory cells on metals enhanced the elution of Ni probably via the release of protons at the interface of the cells and material. (C) 2011 Japanese Society for Investigative Dermatology. Published by Elsevier Ireland Ltd. All rights reserved.
