Background: In children with Down syndrome (DS) the retarded growth potential cause a number of different clinical signs. Morphological deviations and an underdeveloped midface together with hypotonia contribute to increased prevalence of occlusal anomalies. Since the early 1980 ́s orofacial neuro-motor habilitation with palatal plates therapy have been used in Sweden. Aim: to investigate if use...

Objective: The aim of the present study was to evaluate the effects of the hard plate used for the treatment of bruxism, on the growth of the alveolar base of the maxillary bone during a 6 month period. Methods: All the subjects were three to six year old, were healthy and presented dental wear. The children were included as bruxist when their anxiety level was above 0.75%, according to Conners...

To examine the stability of repetitive-sequence (rep) PCR profiles, six species of bacteria were subcultured to blood agar plates and DNA was extracted from the cultures after 24, 48, and 72 h of incubation at 35 degrees C. In addition, the same species were subcultured to fresh blood plates daily and DNA was extracted from the cultures after growth of 5, 10, and 15 subcultures, respectively. r...

Twelve yeast strains isolated from the surface of Italian typical dry-cured hams, belonging to D. hansenii, D. maramus, C. famata, C. zeylanoides and H. burtonii species, and previously selected for their ability to grow in dry-cured ham-like substrates, were screened for antagonistic activity against a toxigenic strain of P. nordicum and inhibition of ochratoxin A (OTA) biosynthesis. On averag...

Matrix metalloproteinases (MMPs) are expressed in cartilage during embryonic development and later during remodeling. Mmp9, although not a collagenase is expressed early in embryogenesis during endochondral ossification and Mmp9 deficiency in mice results in abnormalities that affects growth plates. Mmp13 (collagenase-3), a highly expressed collagenolytic MMP in cartilage and in developing and ...

Most antibiotics were discovered via their inhibition of growth of target organisms. However, yeasts in particular have the capability to adapt metabolic pathways to the availability of nutrients e.g. yeasts can easily switch between respiratory and fermentative pathways in response to oxygen concentration, or can even use both simultaneously. Thus, we cultivated S. cerevisiae BY4741 and C. alb...

PURPOSE To quantitatively evaluate growth plates around the knees in adolescent soccer players utilizing the diffusion-weighted MR imaging (DWI). METHODS The knees and adjacent growth plates of eleven 14-year-old male soccer players were evaluated by MRI before (end of season's summer break) and after two months of intense soccer training. MRI evaluation was conducted in coronal plane by PD-F...

This paper reports a high-yield process to fabricate biomimetic hydroxyapatite nano-particles or nano-plates. Hydroxyapatite is obtained by simultaneous dripping of calcium chloride (CaCl2) and ammonium hydrogen phosphate (NH4)2HPO4 solutions into a reaction vessel. Reactions were carried out under various pH and temperature conditions. The morphology and phase composition of the precipitates w...

While the importance of autocrine-paracrine signaling in vivo is clear, the ability to study the effects of secreted endogenous factors in vitro is hampered by canonical culture platforms. In multi-well plates, the large air-liquid interface gives rise to convective flows that continually mix the fluid disrupting the local diffusion-based accumulation. Simple microchannels provide a more contro...

When stimulated to bend downward by being held at 45 degrees off vertical but unable to penetrate into agar-based media, Arabidopsis roots develop waving and looping growth patterns. Here, we demonstrate that ethylene modulates these responses. We determined that agar-containing plates sealed with low-porosity film generate abiotic ethylene concentrations of 0.1 to 0.3 microL L(-1), whereas in ...
