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

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

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 ...

Effect of Heat-Treatment Time on Bending Properties of Cobolt-Chromium Orthodontic Wires [PDF]
, 2019 Different protocols appear in the literature with respect to heat-treating cobalt-chromium orthodontic wires. The objective was to determine the effect of variable heat-treatment time and method on the bending properties of CoCr wires.

Response of A356 to warm rotary forming and subsequent T6 heat treatment
, 2014 The through-process microstructural effects in A356 subjected to rotary forming at elevated temperatures have been investigated. Macro and micro-hardness testing have been used extensively to track changes in the material from the as-cast state to as ...

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.

Fatigue response of as built DMLS processed Maraging Steel and effects of machining and heat and surface treatments [PDF]
, 2018 The main motivations for this study arise from the need for an assessment of the fatigue performance of DMLS produced Maraging Steel MS1, when it is used in the \u201cas fabricated\u201d state. The literature indicates a lack of knowledge from this point

Molecular Oncology, EarlyView.Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.
