Correlation among pAKT, pERK1/2 and DNA fragmentation index in human cumulus cells to determine oocyte competence

2018

The aim was to correlate specific biological aspects of cumulus cells isolated from individual cumulus-oocyte complexes (COCs) with the clinical outcome of the related embryos.

In Vitro Cytotoxic Effect of Aqueous Extracts from Leaves and Rhizomes of the Seagrass Posidonia oceanica (L.) Delile on HepG2 Liver Cancer Cells: Fo…

2023

Aqueous extracts from Posidonia oceanica’s green and brown (beached) leaves and rhizomes were prepared, submitted to phenolic compound and proteomic analysis, and examined for their potential cytotoxic effect on HepG2 liver cancer cells in culture. The chosen endpoints related to survival and death were cell viability and locomotory behavior, cell-cycle analysis, apoptosis and autophagy, mitochondrial membrane polarization, and cell redox state. Here, we show that 24 h exposure to both green-leaf- and rhizome-derived extracts decreased tumor cell number in a dose–response manner, with a mean half maximal inhibitory concentration (IC50) estimated at 83 and 11.5 μg of dry extract/mL, respecti…

DNA extraction from phytoseiid specimens preserved on a glass slide and molecular diagnostic

2010

This study focuses on the diagnostic of seven species of mite belonging to the family of Phytoseiidae; very important biocontrol agents of phytophagous mites. However, they are morphologically very similar and specific diagnostic is very difficult in fact using the traditional identification methods it is uncertain to identify a species especially when Authors use different characters, very often not stable in the time. In the 60’s M.me Athias-Henriot took into consideration the insemination apparatus that is considered a stable character in the time. According to her, the shape of this apparatus could be considered a major criterion for genus distinction. The aim of the present study is to…

Proteomic analysis of extracellular vesicles shed in vitro by MDA MB 231 breast carcinoma cells

2010

Cross talk between tumor cells and connective tissue plays a key role in tumor progression. The communication is due to the release of signalling molecules from both tumor cells and surrounding stromal cells. Several secreted proteins lack the N-terminal signal peptides and, therefore, they are secreted by alternative unconventional processes such as secretion mechanism mediated by vesicle shedding in the extracellular matrix. Actually, a certain number of proteins, playing roles in some aspects of tumor progression, have been found in shed vesicles. For example, EMMPRIN, carried out in vesicles shed by tumor cells, stimulates matrix metalloproteinase (MMP) production in stromal fibroblasts…

Biological and Proteomic Characterization of the Anti-Cancer Potency of Aqueous Extracts from Cell-Free Coelomic Fluid of Arbacia lixula Sea Urchin i…

2022

Echinoderms are an acknowledged source of bioactive compounds exerting various beneficial effects on human health. Here, we examined the potential in vitro anti-hepatocarcinoma effects of aqueous extracts of the cell-free coelomic fluid obtained from the sea urchin Arbacia lixula using the HepG2 cell line as a model system. This was accomplished by employing a combination of colorimetric, microscopic and flow cytometric assays to determine cell viability, cell cycle distribution, the possible onset of apoptosis, the accumulation rate of acidic vesicular organelles, mitochondrial polarization, cell redox state and cell locomotory ability. The obtained data show that exposed HepG2 cells under…

PECULIARE EVOLUZIONE DELLA SEMEIOTICA NEURORADIOLOGICA DI UN CASO DI MALATTIA DEMIELINIZZANTE CON LESIONI PSEUDOTUMORALI

2013

SCOPO DEL LAVORO Presentiamo un caso di una paziente di 24 anni che giunge alla nostra attenzione per la comparsa di disartria come quadro clinico d’esordio di una forma aggressiva di malattia demielinizzante di cui si valuta l’atipica evoluzione neuroradiologica delle lesioni pseudotumorali che la caratterizzano e le possibili diagnosi differenziali. MATERIALI E METODI La paziente dopo una prima valutazione in PS è stata sottoposta a TC encefalo, ricoverata presso l’U.O. di Neurologia, sottoposta a controlli RM seriati (anche con tecniche avanzate); durante la degenza è stata inoltre effettuata una biopsia stereotassica. RISULTATI La TC ha rilevato almeno tre lesioni ipodense: a sinistra…
