Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Selenium semiconductor core optical fibers

AIP Advances, 2015
Phosphate glass-clad optical fibers containing selenium (Se) semiconductor core were fabricated using a molten core method. The cores were found to be amorphous as evidenced by X-ray diffraction and corroborated by Micro-Raman spectrum.

Persistent luminescence in non-Eu2+-doped compounds : a review [PDF]

, 2013
During the past few decades, the research on persistent luminescent materials has focused mainly on Eu2+-doped compounds. However, the yearly number of publications on non-Eu2+-based materials has also increased steadily.

Photometer for luminescent materials

Journal of Research of the National Bureau of Standards, 1945
In evaluating the usefulness of luminescent materials it is necessary to take into account the behavior of the human eye at low values of luminance. A photometer that provides for the determination of low luminances, with due regard for the characteristic behavior of the eye at such values, is described.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

Molecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Studies on Luminescent Materials. II

NIPPON KAGAKU KAISHI, 1939
(1) ZnOとSiO2の各種の割合より成る珪酸亞鉛マンガン螢光體の2537Aの紫外線及び陰極線の刺戟に依つて生ずる螢光スペクトルを25°C及び-185°Cの温度に於測定し,分光寫眞測光に依つて其の螢光スペクトルのエネルギー分布を求めた.(2) 各種の組成を有する珪酸亞鉛螢光體の螢光の明るさを測定し,メタ珪酸亞鉛螢光體は正珪酸亞鉛と無水珪酸との單なる混合物としてのみ考へることの出來ないことを示した.(3) 珪酸亞鉛螢光體のエネルギー準位を測定し,吸收スペクトル,刺戟スペクトル,螢光スペクトル及び光電傳導現象等に對する理論的解釋を與へた.(4) -185°Cに於ける螢光スペクトルを測定し, 5083A及び5155Aの位置に線スペクトルを生じ ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

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 ...
