Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

Formaldehyde Emission Pattern of Melamine Impregnated Paper Decorated Medium Density Fiberboard and its Furniture Products

open access: yesBioResources, 2023
Melamine-impregnated paper decorated medium-density fiberboard (MIP-MDF) is the main board used for wooden furniture materials in China, and the formaldehyde released from the board and furniture products is harmful to human beings and is a wide concern.

Investigation of 222‐nm ultraviolet C irradiation bactericidal effect on the surgical field in a rabbit model

open access: yesPhotochemistry and Photobiology, EarlyView.
In a rabbit surgical field model seeded with polymicrobial flora, a single dose of 222‐nm UV‐C (500 mJ/cm2) markedly reduced bacterial colonies, achieving a bactericidal effect comparable to 254‐nm UV‐C (200 mJ/cm2), while no UV‐C irradiation showed heavy growth. Wound healing did not differ among groups. Microbiota profiling detected SSI‐relevant taxa

Two-Component Galactic Bulge Probed with Renewed Galactic Chemical Evolution Model

open access: yes, 2012
Results of recent observations of the Galactic bulge demand that we discard a simple picture of its formation, suggesting the presence of two stellar populations represented by two peaks of stellar metallicity distribution (MDF) in the bulge.

Long‐term outcomes of lateral sinus floor elevation: A machine‐learning analysis, systematic review, and meta‐analysis of predictive factors

open access: yesPeriodontology 2000, EarlyView.
Abstract Objectives To quantify long‐term (≥ 5 years) implant survival after lateral sinus floor elevation (LSFE) and to identify clinical predictors of long‐term survival using conventional and machine‐learning meta‐analytic techniques. Methods A systematic search was conducted through MEDLINE, Embase and Scopus.

Seroprevalence and Risk Factors for Hepatitis E Virus in a Metropolis of Northeastern Brazil: A Population‐Based Survey

open access: yesZoonoses and Public Health, EarlyView.
ABSTRACT Introduction Hepatitis E virus (HEV) is a leading cause of acute hepatitis worldwide. While traditionally linked to poor sanitation in endemic areas, evidence shows increasing circulation in developed settings. In Brazil, however, population‐based data remain limited.

Ricci flows, wormholes and critical phenomena

open access: yes, 2008
We study the evolution of wormhole geometries under Ricci flow using numerical methods. Depending on values of initial data parameters, wormhole throats either pinch off or evolve to a monotonically growing state.

Neuromuscular fatigue and loss of torque complexity during severe‐intensity exercise: The role of muscle size

open access: yesExperimental Physiology, EarlyView.
Abstract This study investigated the effect of severe‐intensity exercise on neuromuscular fatigue (NMF) and torque complexity in two muscle groups of different sizes. The NMF of 11 healthy males was assessed through maximal voluntary contractions at the beginning, every minute and at task failure during intermittent isometric exercise performed at an ...

Evaluation of Styrene-based Copolymers and Glutaraldehyde for Medium-density Fiberboard Production

open access: yesBioResources
The performance of medium density fiberboard (MDF) with styrene-based copolymers and glutaraldehyde was evaluated. Styrene/n-butyl acrylate (SBA), styrene maleic anhydride (SMA), and glutaraldehyde (GA) were tested at 1%, 2.5%, and 5% levels.
