Characterizing CD133 and NANOG Expression in Melanoma: Associations with Histological and Epidemiological Parameters.

: Melanoma is an aggressive skin malignancy, and the majority of deaths associated with melanoma result from malignant skin lesions. Our study aims to evaluate the expression of the markers CD133 and NANOG, associated with tumor stem cells, and to analyze their link with epidemiological and histological parameters, thus contributing to early diagnosis and the development of targeted therapies. : We performed a retrospective study in the Mureș Clinical County Hospital, Romania, which included 66 cases of melanoma: 50 primary cutaneous melanomas, 10 metastases, and 6 local recurrences.

The Impact of the COVID-19 Pandemic on Melanoma Diagnosis: A Single-Center Study.

(1) Background: Melanoma represents the most aggressive form of skin cancer, with an increasing incidence and numerous risk factors. The COVID-19 pandemic has led to modifications in work protocols. This study aims to elucidate potential changes in the number and characteristics of primary melanomas diagnosed in the Pathology Department of the Târgu Mureș County Clinical Hospital before, during, and after the COVID-19 pandemic.

A Comprehensive View on the Impact of Chlorogenic Acids on Colorectal Cancer.

Chlorogenic acids are plant secondary metabolites, chemically-polyphenols with similar biological activity, formed through the esterification of quinic acid and hydrocinnamic acid moieties. They are best known for their high concentration in coffee and other dietary sources and the antioxidant properties that they exhibit. Both chlorogenic acids and plant extracts containing significant amounts of the compounds show promising in vitro activity against colorectal cancer.

H-VISTA Immunohistochemistry Score Is Associated with Advanced Stages in Cutaneous and Ocular Melanoma.

Melanoma represents a public health issue. One of the biggest goals of current research is to develop new therapeutic options for patients affected by this aggressive tumor. We conducted a retrospective study including 105 patients diagnosed with cutaneous and ocular melanoma, with stages varying from pT1a to pT4b and pT4e, respectively, and we performed immunohistochemistry reactions with the new potential prognostic marker, VISTA (V-domain Ig suppressor of T cell activation).
