Cardioprotective action of methanolic extract and its isolated compound Kaempferol through mitigating lipotoxicity, oxidative stress and inflammation in the heart.

The current study was designed to evaluate the cardio-protective efficacy of L. methanolic extract (AVME) and kaempferol, which was isolated from AVME in isoproterenol (ISO)-induced cardiotoxicity in rats. The rats were pre-treated with AVME (250 mg/kg body weight) and kaempferol (50 mg/kg BW) for 30 days, respectively, and then administered with ISO (20 mg/100 g body weight) on the 31st and 32nd days.

Isolation and anticancer activity of quercetin from L. against breast cancer cell lines MCF-7 and MDA-MB-231.

Unlabelled: In this study, the active components of the plant were carefully extracted and identified using three solvent systems. After extraction, we used solvent systems to further purify the main flavonoid chemical constituent. As a result of our analytical strategy, which included HPLC analysis, MS/MS spectroscopic analysis, and NMR data-based constructions, quercetin was determined to be the main chemical constituent.

Quantum dots based in-vitro co-culture cancer model for identification of rare cancer cell heterogeneity.

Cancer cell heterogeneity (CCH) is crucial in understanding cancer progression and metastasis. The CCH is one of the stumbling blocks in modern medicine's therapeutics and diagnostics . An in-vitro model of co-culture systems of MCF-7, HeLa, HEK-293, with THP-1 cells showed the occurrence of EpCAM positive (EpCAM+) and EpCAM negative (EpCAM-) heterogenetic cancer cell types labeled with the Quantum Dot antibody conjugates (QD).

Biocompatible Ni-doped CdSe/ZnS semiconductor nanocrystals for cellular imaging and sorting.

Quantum dots (QD) with chemical composition were successfully synthesized using a hydrothermal method and chemical precipitation. The nanocrystalline phase of the nanostructures was isolated and characterized using X-ray diffraction (XRD). The mean crystalline size doped core/shell Ni-dopant range was 9.

Allyl isothiocyanate induces replication-associated DNA damage response in NSCLC cells and sensitizes to ionizing radiation.

Allyl isothiocyanate (AITC), a constituent of many cruciferous vegetables exhibits significant anticancer activities in many cancer models. Our studies provide novel insights into AITC-induced anticancer mechanisms in human A549 and H1299 non-small cell lung cancer (NSCLC) cells. AITC exposure induced replication stress in NSCLC cells as evidenced by γH2AX and FANCD2 foci, ATM/ATR-mediated checkpoint responses and S and G2/M cell cycle arrest.
