Tritium has been used as a tracer in hydrogeological studies to date young groundwater. It was released in massive amounts to the atmosphere by nuclear bomb testing in the 1950’s and early 1960’s. Its activity in the atmosphere peaked around 1963-1964 and has been steadily falling since then due to its half-life of 12.32 years. On the northern hemisphere, where the atmospheric tritium concentration reached much higher levels than on the southern hemisphere, elevated tritium activities in groundwater persist, and thus can still be used to identify groundwater that has recharged during the post-bomb era.

Abstract Introduction/Objective Warthin tumor-like mucoepidermoid carcinoma(WTL- MEC) is one of the subvariant of mucoepidermoid carcinoma. It mimics the histological features of metaplastic Warthin tumors (mWTs). To investigate the clinicopathological, molecular features, and bio-behaviors of WTL-MEC, we retrospected a cohort of 29 WTL- MEC patients. Methods/Case Report The clinicopathological and microscopic data were collected. Dual-color FISH analysis was performed on paraffin-embedded sections of 29 WTL- MEC patients and 16 mWTs patients using a MAML2 break- apart probe. Whole-exome sequencing and whole transcription sequencing were performed on 3 WTL-MEC and 3 typical mucoepidermoid carcinomas (TMEC) patients. Genetic data were bioinformatically analyzed by software MuTect (v1.7), PINDEL (v0.2.5), SnpEff (v3.0), and etc. Results (if a Case Study enter NA) The cohort of WTL-MEC included 10 male and 19 female patients with a median age of 42.3 years (range, 8 to 68 years). Microscopically, the WTL-MEC lesion consisted of multi-cysts with variant shapes and sizes. The cystic spaces were lined by bi-layered and multilayered oncocytic cells. A transition zone between the bi-layered oncocytic epithelium to the multilayered oncocytic epithelium was observed in WTL-MEC. The cords of epidermoid cells and mucous cells could be found. The germinal center, extensive hyalinization, and mucus extravasation were observed. MAML2 rearrangement was identified in 29 (100%) WTL-MEC. No rearrangement was observed in mWTs by FISH. MET was the most commonly mutated gene in TMEC, and PRDM11 was the most commonly mutated gene in WTL-MEC. Twenty-nine patients were alive without recurrent at the end of the follow-up periods(5–128M). One Patient died due to the metastasis to the lung. Conclusion compared with mWTs, WTL- MEC usually presented in the young, non-smoking female. The histological feature of WTL-MEC depended mainly on the transition zone of the bi-layered oncocytic epithelium and the multilayered oncocytic epithelium. And MAML2 status can confirm the diagnosis. CRTC1-MAML2 and PRDM11 mutations appear to be the main driver event of WTL-MEC. Prognosis was usually favorable, but recurrence or metastasis may rarely occur.
