This study aimed to investigate the photobiological action of cocoa solution on a human fibroblast cell line (HFF-1) exposed to ultraviolet B (UVB) radiation. Three experimental models were utilized, where fibroblast cells were treated with different concentrations of cocoa as follows: 50; 100; 250; 500; 750; 1000 or 1500 µg/ml and concomitantly exposed to UVB 7 kJ/m for 10 min. The following parameters were examined 1) analysis of the pre-treatment action of cocoa; 2) investigation of the co-treatment activity of cocoa at the time of exposure; and 3) study the effect of cocoa in the post-treatment of the damage initiated by UVB.

For this, the PubChem database of the NIH (National Institutes of Health) was used to obtain the SMILE canonical form of the bioactive molecules, and the free software PASS Online (Prediction of Activity Spectra for Substances) from the Way2Drug portal. Also, we conducted an in vitro experiment using a chronic myeloid leukemia (CML) cell line (K562) to confirm some results found in in silico investigation.

This study focused on the characterization of 23 OXA-48-like carbapenemase-producing isolates using phenotypic and molecular tests. Phenotypic determination of the presence of β-lactamases was performed using the extended-spectrum beta-lactamase (ESBL) NP test, and phenotypic determination of the presence of carbapenemase was based on the Carba NP test.

Renal cell carcinoma (RCC) is the most common type of renal cancer, considered the seventh most common type of cancer in the Western world. The most frequently altered genes described as altered are VHL, PBRM1, SETD2, KDM5C, PTEN, BAP1, mTOR, TP53, TCEB1 (ELOC), SMARCA4, ARID1A, and PIK3CA.
