Measurement of Ionized Calcium as Supplementary Marker of Bone Metastasis in Breast Cancer
The serum concentrations of ionized calcium (iCa), corrected automatically for serum pH, were measured in 67 cases with breast cancer (16 positive cases and 51 negative cases for bone metastasis). The serum concentration of iCa in the cases of positive bone metastasis was significantly higher than that in the negative cases (p<0.005). As osteoclastic bone metastasis occurred frequently in breast cancer, the measurements of serum concentrations of iCa might be of help as a supplementary marker of the diagnosis of bone metastasis
頸部リンパ節転移が嚢胞を呈した甲状腺不顕性癌の1例
頸部リンパ節転移が,嚢胞を呈した甲状腺不顕性癌の1例を経験したので報告した.症例31歳男性,左側頸部腫瘤を主訴として来院.側頸部嚢胞と診断したが,摘出腫瘤を組織学的に検討した結果,甲状腺癌のリンパ節転移と判明した.The purpose of this paper is to report a case of minimal carcinoma of the thyroid manifested by a cystic metastasis to the cervical lymph nodes which mimicked a lateral cervical cyst in a 31-year-old male and to discuss the clinical significance of cystic metastasis from papillary adenocarcinoma of the thyroid
Anion-Dependent Potential Precycling Effects on Lithium Deposition/Dissolution Reaction Studied by an Electrochemical Quartz Crystal Microbalance
The electrochemical
quartz crystal microbalance technique was employed
to study the initial stage of the electrodeposition and dissolution
of lithium utilizing three kinds of electrolyte solutions such as
LiPF<sub>6</sub>, LiTFSI, or LiFSI in tetraglyme. The native-SEI (solid–electrolyte
interphase) formed by a potential prescan before lithium deposition/dissolution
in all three solutions. Simultaneous additional SEI (add-SEI) deposition
and its dissolution with lithium deposition and dissolution, respectively,
were observed in LiPF<sub>6</sub> and LiTFSI. Conversely, the add-SEI
dissolution with lithium deposition and its deposition with lithium
dissolution were observed in LiFSI. Additional potential precycling
resulted in the accumulation of a “pre-SEI” layer over
the native-SEI layer in all of the solutions. With the pre-SEI, only
lithium deposition/dissolution were significantly observed in LiTFSI
and LiFSI. On the basis of the potential dependences of the mass and
resistance changes, the anion-dependent effects of such a pre-SEI
layer presence/absence on the lithium deposition/dissolution processes
were discussed
