Biochem/physiol Actions

BTC is a selective estrogen receptor (ER) modulator (SERM) that acts as a selective estrogen mimic (SEM). BTC has been found to be both estrogenic and antiproliferative in ER-positive endocrine-resistant breast cancer cell lines that overexpress protein kinase C alpha (PKCα), which is often associated with tamoxifen resistance. BTC caused regression of endocrine-resistant breast cancer xenografts, and did not support the growth of hormone-dependent xenografts in vivo or cause an increase in uterine weight. As in the case with raloxifene and estradiol, BTC tumor regression was accompanied by the exit of ERα from the nucleus, suggesting extranuclear ERα may be involved in the mehanism of action.

Three-dimensional (3D) printing technique has received exceptional global attention as it can create a myriad of high-resolution architectures from digital models. In the present study, 3D-printed metal-organic frameworks (MOFs) were shaped into several geometries via direct ink writing, which overcomes

Metal-organic frameworks (MOFs) are emerging class of porous materials that attracted tremendous attention as eco-friendly photocatalysts. However, poor charge separation in most MOFs largely thwarts their photocatalytic performance. In this work, Materials of Institut Lavoisier-100(Fe) (MIL-100 (Fe)) based on iron

In this study, a metal organic framework MIL-100(Fe) was synthesized for rhodamine B (RB) removal from aqueous solutions. An experimental design was conducted using a central composite design (CCD) method to obtain the RB adsorption data (n = 30) from batch experiments.
