The patients ranged from 51 to 79 years (mean 68 y). All were FIGO stage IIIC to IV at initial surgical staging, and 3 were dead from the disease at an average of 8.6 months follow-up. In addition to the expected findings, other notable morphologic features included tumor giant cells (4/4), osteoclast-like giant cells (1/4), patchy myxoid stroma (4/4), and only infrequent cytoplasmic cross striations (1/4). The tumors

in all 4 cases were positive for myogenin, myo-D1, smooth muscle actin, desmin, muscle-specific actin (HHF-35), and CD10; 3 (75%) of 4 cases were positive for calponin ML323 supplier and CD56; all cases were negative for cytokeratin 7, synaptophysin, epithelial membrane antigen, placental-like alkaline phosphatase, chromogranin, and a pan-keratin. Twenty-three cases have been reported earlier in the English-language literature

between 1969 and 2009. In combination with the current 4, the 27 patients had an age range of 35 to 87 years (mean 66.33 y). Only 1 patient was deemed inoperable; most had staging operations. Following their initial evaluations, 16 (59%) were found to have extrauterine extension of disease. At follow-up, 73% (19/27) were dead from the disease and 19.2% had no evidence of recurrence. Ten (53%) of the 19 deaths occurred within 6.5 months of initial evaluation. Stage at presentation did not have any significant impact MK2206 on outcome: 73% of the 11 patients with uterus-confined disease at presentation were dead from the disease at follow-up, a rate of disease-associated death that was nearly identical to the 75% in the 16 patients with extrauterine disease at presentation. A wide variety of neoadjuvant

and adjuvant therapies were administered, which did not appear to significantly impact outcomes. These data indicate that pleomorphic rhabdomyosarcoma selleck chemical of the uterine corpus is a highly aggressive, rapidly progressive tumor with a high case-fatality rate.”
“We report on a new method for the microextraction and determination of zinc (II). The ion is accumulated via ionic-liquid cold-induced aggregation dispersive liquid-liquid microextraction (IL-CIA-DLLME) followed by flame atomic absorption spectrometry (FAAS). The ionic liquid (IL) 1-hexyl-3-methylimidazolium hexafluorophosphate is dispersed into a heated sample solution containing sodium hexafluorophosphate as a common ion source. The solution is then placed in an ice-water bath upon which a cloudy solution forms due to the decrease of the solubility of the IL. Zinc is complexed with 8-hydroxyquinoline and extracted into the IL. The enriched phase is dissolved in a diluting agent and introduced to the FAAS. The method is not influenced by variations in the ionic strength of the sample solution. Factors affecting the performance were evaluated and optimized.
