Short-term perinatal oxygen exposure may impair lung development in adult mice

Kumar, Vasantha H. S; Wang, Huamei; Nielsen, Lori.
Biol. Res; 53 (), 2020
BACKGROUND: Hyperoxia at resuscitation increases oxidative stress, and even brief exposure to high oxygen concentrations during stabilization may trigger organ injury with adverse long-term outcomes in premature infants. We studied the long-term effects of short-term perinatal oxygen exposure on cell cyc...

Braz. j. microbiol; 49 (3), 2018
Abstract Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lun...

Histochemical and immunohistochemical differences between solitary oral fibroma and fibrous papule of the face

Henriques, Águida Cristina Gomes; Freitas, Roseana de Almeida; Pires, Bruno Cunha; Gurgel, Clarissa Araújo; Santos, Jean Nunes dos.
An. bras. dermatol; 91 (5), 2016
Abstract: Background: The morphological similarities between fibrous papules of the face and multiple sporadic oral fibromas were mentioned long ago and a relationship between them has been reported in the literature. Objective: The aim of this study was to evaluate the participation of mast cells, ela...
