Influence of Ultra-low Temperature Thermal Fatigue on Microstructure and Mechanical Property of Z2CND18.12 Austenitic Stainless Steel

Yuanzineng kexue jishu
At present, ice plug technology is often used in the maintenance process of nuclear power plants to isolate part of the main pipeline and use refrigerant such as liquid nitrogen for ultra-low temperature treatment, so that the internal fluid is frozen to

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Ultra-Low Temperature Nuclear Magnetic Resonance [PDF]

IOP Conference Series: Materials Science and Engineering, 2017
Because NMR spectroscopy requests more sensitivity and more resolution, high-frequency and high-power microwave irradiation of electron spins in a magnetic field, Dynamic Nuclear Polarization (DNP) is becoming a common partner for fast sample spinning NMR experiments.

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Hydrogen transport and embrittlement in 300 M and AerMet100 ultra high strength steels [PDF]

, 2010
This paper describes how hydrogen transport affects the severity of hydrogen embrittlement in 300 M and AerMet100 ultra high strength steels. Slow strain rate tests were carried out on specimens coated with electrodeposited cadmium and aluminium-based

ULT freezer performance and dual-temperature storage in a modern biobank: preserving sample integrity during transition

Journal of Laboratory Medicine
This study evaluated temperature stability, warm-up characteristics, and energy consumption of ultra-low temperature (ULT) freezers operated at −80 °C, −70 °C, and −60 °C, to support sustainable storage practices in biobanking.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

Molecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.
