Aim: Systematic literature review to determine the different ways of adipose-derived mesenchymal stem cells administration in humans with luminal refractory and perianal fistulizing Crohn's disease.

Methods: It was conducted a search for articles (from 2008 to 2018) on PubMed and ScienceDirect databases using the keywords Crohn's disease, fistulizing Crohn's disease, luminal Crohn's disease and transplantation of mesenchymal stem cells or mesenchymal stem cells or stromal cells.

Assessment of the toxicogenic effects and cell death potential of the ester (Z)-methyl 4-((1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)amino)-4-oxobut-2-anoate in combination with cisplatin, cyclophosphamide and doxorubicin.

Despite rapid advances in both the early detection and treatment of cancer, the mortality from this disease remains high, which justifies the development of new products that are more selective and effective and have fewer side effects. Accordingly, a novel ester was synthesized that contains two pharmacophores with important biological activities: (I) 4-aminoantipyrine, which has anti-inflammatory and antioxidant effects, and (II) the pharmacophore 1,4-dioxo-butenyl, which has cytotoxic activity. When administered alone, this compound is non-genotoxic, and it does not cause an increasing in splenic phagocytosis.

Carboxytherapy: Controls the inflammation and enhances the production of fibronectin on wound healing under venous insufficiency.

To examine the influence of carboxytherapy on wound healing under venous insufficiency, full-thickness excisional wounds were created on Wistar rats.

Calcitriol combined with calcium chloride causes apoptosis in undifferentiated adipose tissue-derived human mesenchymal stem cells, but this effect decreases during adipogenic differentiation.

Calcitriol, the bioactive hormone of vitamin D, is currently linked to several diseases, such as obesity and gain of adipose mass, due to its liposolubility and, consequently, its sequestration by adipocytes. As rates of obesity continue to increase, research on the biology of weight gain should be encouraged. This study evaluated the effects of calcitriol combined with CaCl on adipose tissue-derived human mesenchymal stem cells.

New Bis copper complex ((Z) -4 - ((4-chlorophenyl) amino) -4-oxobut-2-enoyl) oxy): Cytotoxicity in 4T1 cells and their toxicogenic potential in Swiss mice.

Copper (II) complexes are promising in the development of new synthetic models for cancer treatment. In this context, we synthesized a new copper complex containing the pharmacophore group 1,4-dioxo-2-butenyl, the Bis(((Z)-4-((4-chlorophenyl) amino)-4-oxobut-2-enoyl)oxy) copper compound and we evaluated its antitumor activity in 4 T1 murine mammary adenocarcinoma cells and their toxicogenic effect in Swiss mice. The compound demonstrated cytotoxicity and genotoxicity to 4 T1 cells, and after cell cycle arrest in G1, which occurred by the increase in ATM and p21 expression, it induced the cells to apoptosis by increasing BAX and caspase-7.
