Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Characterization of optimized Na+ and Cl? liquid membranes for use with extracellular, self-referencing microelectrodes

, 2008
Self-referencing with ion-selective microelectrodes (ISMs) is a useful approach for monitoring near-real-time ion flux near single cells and across epithelia. While ISMs for H+, Ca2+, and K+ have been optimized for use with self-referencing, ISMs for two

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Genotoxic and antigenotoxic properties of selenium compounds in the in vitro micronucleus assay with human whole blood lymphocytes and tk6 lymphoblastoid cells

The Scientific World Journal, 2006
Selenium is known to possess both genotoxic and antigenotoxic properties. In the present study, we have evaluated the genotoxicity and antigenotoxicity of three selenium compounds (sodium selenate, sodium selenite and selenous acid) by measuring in vitro

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Dissociation Phenomena of Sodium Compounds

The Journal of the Society of Chemical Industry, Japan, 1970
すでに報告したカリウム化合物にひきつづき, 四極子型質量分析計とクヌーゼンセル型イオン源を組合せた装置により, ナトリウム硫酸塩および炭酸塩の熱解離反応を検討した。硫酸ナトリウムについては, 1,200～1,500°K の範囲で検討し, 熱解離生成物として Na, Na2O, O2, SO および SO2 を検出した。一方, 炭酸ナトリウムについては, 1,170～1,550°K の範囲で検討し, C, 0, Na, CO, O2, NaOH, Na2O および CO2 を検出した。しかしいずれの場合も NaO, Na2O2など Na2O 以外のナトリウム酸化物は確認できなかった。また, 硫酸塩の場合には SO, SO2 以外の硫黄酸化物は検出されなかった ...
