Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

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

open access: yesMolecular 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 ...

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

open access: yesMolecular 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.

Study on Welding Process of Solid Phase Welding by Post Heat Treatment

open access: yesJournal of the Japan Welding Society, 1971
固相圧接における後熱温度,後熱時間,接合変形度の影響を検討した結果,次のような結論を得た.1.後熱処理による接合状況の進行過程は,後熱温度,後熱時間,接合変形度によって左右され,アレニウスの式を満足する.2.後熱初期の回復現象によって起る接合部に残留する弾性応力の緩和と,さらには後続する再結晶現象によって,接合境界の原子の移動,再配列が進み接合強さは向上する.3.接合境界状態の改善と母材の軟化現象との総合効果によって,継手の機械的性質は決定し,材質,接合変形度,温度によって定まるほぼ一定の後熱時間で最大値がえられた.4.後熱温度が高くなると,空洞の球状化および集合が起る結果,軟化によって低下した接合強さに再び増加が認められ,接合変形度の差の影響はなくなる傾向にある.
