Abstract
Advanced antibacterial biomaterials can help reduce the severe consequences of infections. Using copper compounds is an excellent option to achieve this goal; they offer a combination of regenerative and antimicrobial functions. In this study, new CuCl2-doped sol-gel coatings were developed and physicochemically characterised. Their osteogenic and inflammatory responses were tested in vitro using human osteoblasts and THP-1 macrophages. Their antibacterial effect was evaluated using Escherichia coli and Staphylococcus aureus. The Cu influence on the adsorption of human serum proteins was analysed employing proteomics. The materials released Cu2+ and were not cytotoxic. The osteoblasts in contact with these materials showed an increased ALP, BMP2 and OCN gene expression. THP-1 showed an increase in pro-inflammatory markers related to M1 polarization. Moreover, Cu-doped coatings displayed a potent antibacterial behaviour against E. coli and S. aureus. The copper ions affected the adsorption of proteins related to immunity, coagulation, angiogenesis, fibrinolysis, and osteogenesis. Interestingly, the coatings had increased affinity to proteins with antibacterial functions and proteins linked to the complement system activation that can lead to direct bacterial killing via large pore-forming complexes. These results contribute to our understanding of the antibacterial mechanisms of Cu-biomaterials and their interaction with biological systems.

Abstract
Objective. The aims of this study are to compare 2 origins of adipose-derived mesenchymal stem cells (MSCs) (omentum and subcutaneous) from 2 pathologies (morbid obesity and cancer) vs healthy donors. Adipose tissue has revealed to be the ideal MSC source. However, in developing adipose-derived stem cells (ASCs) for clinical use, it is important to consider the effects of different fat depots and also the effect of donor variability. Methods. We isolated and characterized the membrane markers and differentiation capacities of ASCs obtained from patients with these diseases and different origin. During the culture period, we further analysed the cells' proliferation capacity in an in vitro assay as well as their secretome. Results. Adipose-derived stem cells isolated from obese and cancer patients have mesenchymal phenotype and similar cell proliferation as ASCs derived from healthy donors, some higher in cells derived from subcutaneous fat. However, cells from these 2 types of patients do not have the same differentiation potential, especially in cancer patients from omentum, and exhibit distinct secretion of both pro-inflammatory and regulatory cytokines, which could explain the differences in use due to origin as well as pathology associated with the donor. Conclusion. Subcutaneous and omentum ASCs are slightly different; omentum generates fewer cells but with greater anti-inflammatory capacity. Adipose-derived stem cells from patients with either obesity or cancer are slightly altered, which limits their therapeutic properties.

Abstract
AIM To assess KRAS G12D mutation detection by droplet digital PCR (ddPCR) in stool-derived DNA from colorectal cancer (CRC) patients.
METHODS In this study, tumor tissue and stool samples were collected from 70 patients with stage I-IV CRC diagnosed by preoperative biopsy. KRAS mutational status was determined by pyrosequencing analysis of DNA obtained from formalin-fixed paraffin-embedded (FFPE) tumor tissues. The KRAS G12D mutation was then analyzed by ddPCR in FFPE tumors and stool-derived DNA from patients with this point mutation. Wild-type (WT) tumors, as determined by pyrosequencing, were included as controls; analysis of FFPE tissue and stool-derived DNA by ddPCR was performed for these patients as well.
RESULTS Among the total 70 patients included, KRAS mutations were detected by pyrosequencing in 32 (45.71%), whereas 38 (54.29%) had WT tumors. The frequency of KRAS mutations was higher in left-sided tumors (11 located in the right colon, 15 in the left, and 6 in the rectum). The predominant point mutation was KRAS G12D (14.29%, n = 10), which was more frequent in early-stage tumors (I-IIA, n = 7). In agreement with pyrosequencing results, the KRAS G12D mutation was detected by ddPCR in FFPE tumor-derived DNA, and only a residual number of mutated copies was found in WT controls. The KRAS G12D mutation was also detected in stool-derived DNA in 80% of all fecal samples from CRC patients with this point mutation.
CONCLUSION ddPCR is a reliable and sensitive method to analyze KRAS G12D mutation in stool-derived DNA from CRC patients, especially at early stages. This non-invasive approach is potentially applicable to other relevant biomarkers for CRC management.

Abstract
Exosomes are small extracellular vesicles secreted to the extracellular environment by several cell types, including tumor cells. It has been demonstrated that exosomes have an important role in intercellular communication, but they have recently been implicated in various tumor processes, including the oncogenic transformation of cells in the tumor microenvironment, tumor drug resistance, and the transport of tumor factors. Tumors appear to use exosomes to dialogue with and transform neighboring cells to create an ideal environment for their growth and expansion. On the other hand, the structure and function of exosomes may make them useful in cancer diagnosis and prognosis, because they contain molecules that could serve as biomarkers, including oncogenes, miRNAs, and certain proteins. They have the ability to travel via body fluids, from which they could be isolated and used to transport drugs to specific targets. This review aims to provide an update on the role of exosomes derived from breast cancer cells.
