ABSTRACT Introduction: It is recently suggested that titanium dioxide (TiO2) nanoparticles can be added to bracket luting agents in order to reduce bacterial activity and protect the enamel. However, it is not known if this addition can affect the shear bond strength (SBS) below clinically acceptable l...
Este trabalho avaliou a interferência do estresse subletal em pH ácido na sobrevivência de
Lactobacillus rhamnosus GG em suco misto de juçara e manga com pH ajustado para 3,0 e 3,5 e a resistência desta bactéria ao trato gastrointestinal simulado in vitro durante 28 dias de
armazenamento a 6,0 °C....
Objetivo: Avaliar e comparar a rugosidade superficial e a atividade dos osteoblastos em contato com uma nova superfície bioativa e nanoestruturada de titânio grau 4 revestida com vidro bioativo contendo fosfato de cálcio, sintetizada pelo método sol-gel. Material e método: Sessenta e três discos...
Introdução: Quando introduzidos no meio bucal, os bráquetes cerâmicos podem sofrer alterações em sua estrutura provocadas pelo processo de degradação química e mecânica do material. Objetivo: Este estudo avaliou a rugosidade superficial de bráquetes cerâmicos e se eles sofreram alteração...

Prostaglandin F2α (PGF2α) determines luteolysis in cattle, and the ability to manipulate its endogenous synthesis is indispensible for large-scale animal breeding. Estradiol (E2) and progesterone (P4) modulate several molecular pathways in endometrial cells, including the synthesis of PGF2α; however, ...
Background: All-trans retinoic acid (ATRA), a vitamin A-derived active metabolite, exerts important functions in hair biology. Previous studies indicated that excess ATRA hampered hair follicle morphogenesis and cyclic regeneration in adulthood, but other studies stated that ATRA promoted hair growth. De...

Background: Capsicum is a genus of an important spice crop that belongs to the chili lineage. However, many Capsicum species (family Solanaceae) are known to be recalcitrant to genetic transformation and in vitro regeneration, thus hampering the effort in using Capsicum species for detailed biological in...
Objective: to compare the adhesive strength in dentin of three universal adhesive systems in vitro by means of the shear test. materials and methods: seventy-five bovine teeth were selected and cut. dentin was exposed from the buccal surface of the crowns with 220 grit sandpaper, and samples were then in...
Abstract Objective To determine which mode and potency of electrocoagulation, using a modern electrosurgical generator, yields the smallest unobstructed area of the Fallopian tubes. Methods In an experimental study, tubes from 48 hysterectomies or tubal ligation were evaluated. Tubes were randomly al...
Trichinella spiralis es la especie que causa la mayoría de los casos de infección humana en todo el mundo. Se comunicó que el contacto de los eritrocitos con concentrados de larvas recién nacidas (LRN) no viables provoca la disminución de ácido siálico globular. El objetivo del trabajo fue estudia...
