In this study, the BNH polymers produced by ammonia borane (AB) thermolysis under isothermal conditions were investigated. Polyaminoborane (PAB) and diammoniate of diborane (DADB) form upon releasing the first equivalent of H at 85 °C, followed by the formation of cross-linked polyborazylene (PB) at 140 °C. Polyiminoborane (PIB) was not detected under these conditions.

The Brazilian Ministry of Health has defined the physical and care structure of FBC. Their care model includes appropriate practices, good maternal and infant outcomes, and the promotion of positive experiences for women during childbirth.

The draft genome has a completeness index of 99.3%, spans 2,736,418 base pairs, has a guanine-cytosine content of 37.
View Article and Find Full Text PDFFreestanding birth centers (FBCs) in Brazil are regulated to provide care for women with a straightforward pregnancy. The systematization of the literature on FBCs can broaden our knowledge of these facilities. We conducted a scoping review to answer the following research question: "What are the characteristics of the model of care in freestanding birth centers in Brazil?".

Methods: Four decontamination methods [chlorhexidine (CHX), electrolytic treatment (GS), curcumin (CUR), xanthohumol (XN)] were compared in four independent experiments, three with a 2D peri-implant mucosa model on titanium surfaces and another on a 3D peri-implant mucosa model. These decontamination procedures were tested for their antibacterial effect using a multispecies biofilm model with Streptococcus oralis, Actinomyces naeslundii, Veillonella dispar, and Porphyromonas gingivalis for 24 h.
