Electron microprobe dating of lunar zirconolite

open access: yesJournal of Analytical Science and Technology
Zirconolite is an accessary mineral occurred in the lunar basaltic and granitic rocks and contains relatively high contents of U, Th, and Pb, which is attractive for age dating.

Gemological and Chemical Characterization of Gem-Quality Titanite from Morocco

open access: yesCrystals
Titanite is a widespread accessory mineral in igneous, metamorphic, and hydrothermal rocks, but few comply with gem-grade requirements. Previous studies on Moroccan titanite focused on elementary composition and U-Pb dating.

Nature and timing of Late Mississippian to Mid-Pennsylvanian glacio-eustatic sea-level changes of the Pennine Basin, UK [PDF]

open access: yes, 2012
The Pennine Basin of northern England contains a comparatively complete Serpukhovian– Moscovian succession characterized by high-resolution ammonoid zonation and cyclic paralic sedimentation.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

U-Th-Pb Dating of Monazite by LA-ICP-MS Using Ablation Spot Sizes of 16 μm and 10 μm

open access: yesYankuang ceshi, 2016
Monazite is a common geological chronometer and has complex textures and different chemical domains. Meaningful U-Th-Pb ages for different domains can be obtained only using a suitably small laser beam spot.

Therapeutic strategies for MMAE‐resistant bladder cancer through DPP4 inhibition

open access: yesMolecular Oncology, EarlyView.
We established monomethyl auristatin E (MMAE)‐resistant bladder cancer (BC) cell lines by exposure to progressively increasing concentrations of MMAE in vitro. RNA sequencing showed DPP4 expression was increased in MMAE‐resistant BC cells. Both si‐DPP4 and the DPP4 inhibitor sitagliptin suppressed the viability of MMAE‐resistant BC cells.

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

open access: yesMolecular 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 ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Dating of ice cores from Vernagtferner (Austria) with fission products and lead-210 [PDF]

open access: yes, 1982
Fission product (90Sr_ 90y, I37CS, total beta) and 2tOPb_210pO activities were measured in core samples from the temperate vernagtferner (3150 m altitude, Oetztal Alps, Austria).
