Mycophenolate mofetil (MMF) is a widely prescribed immunosuppressive agent after solid organ transplantation. Potential teratogenic effects in utero exposure to MMF experimental studies and clinical observations humans has been postulated recent literature. However, specific pattern of malformation not identified yet. We present newborn patient, born recipient renal transplantation, who became pregnant while taking as therapy. The exhibited cleft lip palate, bilateral microtia atretic...

The impact of commercial demand on fruits explored through extractivism requires sustainable production strategies. Among these strategies is seedling propagation for reforestation and/or plantations. substrate and its the quantity quality propagated plants are critical aspects propagation. Hancornia speciosa, commonly known as mangabeira, a native fruit species that has been primarily extractivism; thus, goal this study was to assess early development H. speciosa var. seedlings in different...
