Integrative Computational and Experimental Approaches Reveal the Protective Role of Moderate Caffeine Intake Against Apical Periodontitis Induced Bone Loss

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To investigate whether moderate systemic caffeine intake modulates the progression of apical periodontitis (AP) and associated alveolar bone loss, combining in vivo rat experiments with in silico molecular docking to explore potential mechanisms. Methodology Male Wistar rats were randomly assigned to four groups (n = 8 per group): control,

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

open access: yesJournal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

The mechanism of eutectic growth in highly anisotropic materials

open access: yesNature Communications, 2016
The origins of non-periodic growth features observed in irregular eutectics have been a source of controversy. Here authors use time-resolved X-ray microtomography during eutectic growth of an alloy to show how competing models can be extended and ...

Analysis of the obliteration of the root canal: an investigation with Micro-CT [PDF]

open access: yesRevista de Odontologia da UNESP
Introduction Traumatized teeth may undergo calcific metamorphosis of the pulp, a factor which makes endodontic treatment difficult due to the total or partial obliteration of the root canal. Objective To compare the existence of root canal lumen between

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Comparison of elastic properties of periodic and aperiodic porous structures produced by additive methods

open access: yesActa Polytechnica CTU Proceedings
The aim of this work was to design, print, and examine elastic properties of porous structures with various parameters and beam distributions. These structures, generated using an algorithm, featured three types of lattices: octet, cubic, and Voronoi ...
