Cytotoxic Evaluation in HaCaT Cells of the Pa.7 Bacteriophage from Cutibacterium (Propionibacterium) acnes, Free and Encapsulated Within Liposomes.

Introduction: Acne is a multifactorial disease involving the colonization of skin follicles by Cutibacterium (formerly Propionibacterium) acnes. A combination of different retinoid-derived products, antibiotics, and hormonal antiandrogens are used to treat the disease, but these treatments require extended periods, may have secondary effects, are expensive, and not always effective. Owing to antibiotic resistance, the use of bacteriophages has been proposed as an alternative treatment. However, if they are intended for a cosmetic or pharmaceutical use, it is necessary to evaluate the safety of the phages and the preparations containing them. Materials and Methods: In this study, the cytotoxicity of Pa.7 bacteriophage was evaluated in HaCaT cells, along with a liposome suitable for their encapsulation, using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and trypan blue assays. Results: We found that Pa.7 was not cytotoxic for HaCaT cells. Also, 30 mM of liposomes, or below are considered noncytotoxic concentrations. Conclusion: Phages encapsulated in the liposomes presented in this study can be used safely for skin treatments.

Novel complexes with ONNO tetradentate coumarin schiff-base donor ligands: x-ray structures, DFT calculations, molecular dynamics and potential anticarcinogenic activity.

The synthesis of eight novel Zn(II), Co(II), Cu(II), Ni(II) and Pt(II) complexes (2-9) derived from the ONNO tetradentate coumarin Schiff-Base donor ligands, L1 and the novel L2, was performed. All compounds were characterized by analytical, spectrometry and spectroscopy techniques. Complexes 2-4 were also characterized by DFT calculations and the structures of 5 and 6 were determined by single-crystal X-ray diffraction analysis. A cytotoxicity study was carried out through an MTT assay in the carcinogenic cell line HeLa and the noncarcinogenic cell lines HFF-1 and HaCaT. The results indicated that among all the evaluated compounds, 2 and 6 presented the best anticarcinogenic potential against HeLa cells with an IC50 of 3.5 and 4.1 µM, respectively. In addition, classical molecular dynamics simulations were performed on the synthesized coordination compounds bound to G4 DNA architectures in the scope of shedding light on their inhibition mode and the most conserved interactions that may lead to the biological activity of the compounds.

Recommendations for early diagnosis of Developmental Dysplasia of the Hip (DDH): working group intersociety consensus document.

This consensus document has been prepared by a multidisciplinary group of experts (Paediatricians, Radiologists, Paediatric Orthopaedics) and it is mainly aimed at paediatricians, hospitals and primary care providers. We provide recommendations for the early diagnosis and treatment of Developmental Dysplasia of the Hip (DDH) and indications on its management.
