Modulation of gut microbiome in the treatment of neurodegenerative diseases: A systematic review.

Background And Aims: Microbiota plays an essential role in maintaining body health, through positive influences on metabolic, defensive, and trophic processes and on intercellular communication. Imbalance in intestinal flora, with the proliferation of harmful bacterial species (dysbiosis) is consistently reported in chronic illnesses, including neurodegenerative diseases (ND). Correcting dysbiosis can have a beneficial impact on the symptoms and evolution of ND.

Quantitative examination of factors influencing the colour reproduction ability of lithium disilicate glass-ceramics.

Background: Effects of ceramic translucency, layer thickness, and substrate colour on the shade of lithium disilicate glass-ceramic restorations proved to be significant in several studies, however, quantitative, numerical results on the relationship between the colour difference and these parameters are still lacking. The purpose of this in vitro study was to quantitatively determine how the colour reproduction ability of a lithium disilicate glass-ceramic is affected by its translucency, layer thickness, and substrate colour.

Methods: Ceramic samples were prepared from A2 shade IPS e.

Assessment of a novel electrochemically deposited smart bioactive trabecular coating (SBTC®): a randomized controlled clinical trial.

Objectives: A randomized controlled clinical trial of dental implants was conducted to compare the clinical properties of a novel electrochemically deposited calcium phosphate coating to those of a common marketed surface treatment.

Material And Methods: Forty implants of the same brand and type were placed in 20 fully edentulous participants requiring mandibular implantation. The two study groups were defined by the surface treatment of the implants.

Smart contracts and homomorphic encryption for private P2P energy trading and demand response on blockchain.

Blockchain technology offers great value in terms of decentralization, data integrity, transparency, and traceability, however the transactional data is public, and accessible raising concerns about violating privacy regulations. For example, in the peer-to-peer energy trading and demand response use cases, the data stored in blockchain may allow a third party to infer the load profiles or even identify the behind the meter assets. In this paper, we employ homomorphic techniques to encrypt the energy transactional data stored on the blockchain allowing the smart contracts functions responsible for implementing the business logic of the energy flexibility trading and settlement to perform computations on encrypted data.

Trisomy 22: First and Second Trimester Cytogenetic Analysis and Phenotypic Presentation in a Series of Seven Cases.

Introduction: Trisomy 22 is a chromosomal disorder rarely encountered prenatally. Even fewer live births are observed and generally correspond to confined placental mosaic trisomy 22, or even more uncommonly, to true fetal mosaic trisomy 22.

Case Presentation: We examine and describe a series of seven cases of trisomy 22 encountered prenatally in terms of their cytogenetic and phenotypic presentations and discuss their interrelationships along with case management and outcomes.
