This study presents retrospective 8-year clinical performance data from a patient cohort treated with immediately loaded maxillary full prostheses supported by zygomatic implants combined with implants placed in the nasopalatine canal, as a treatment for severely resorbed edentulous ridges. A retrospective analysis was conducted on data of maxillary edentulous patients with severe bone atrophy. All of them received zygomatic implants in combination with an implant placed in the nasopalatine foramen and an immediately loaded fixed temporary prosthesis in the first 24 hours.

Article Synopsis
  • - The paper reviews how enriched environments (EE) influence epigenetic changes in the brain under stressful conditions through an analysis of 14 relevant studies from databases like PubMed and Scopus.
  • - Findings indicate that after EE exposure, there are notable changes in microRNA expression and histone modifications, particularly in the prefrontal cortex and hippocampus, which affect brain plasticity and potentially improve behavioral outcomes.
  • - The study suggests that EE could serve as a simple, non-drug method to enhance brain health and mitigate symptoms associated with brain-affecting conditions.

Extensive research has delved into the impact of environmental circumstances on the pacing and performance of professional marathon runners. However, the effects of environmental conditions on the pacing strategies employed by marathon participants in general remain relatively unexplored. This study aimed to examine the potential associations between various environmental factors, encompassing temperature, barometric pressure, humidity, precipitation, sunshine, cloud cover, wind speed, and dew point, and the pacing behavior of men and women.

Article Synopsis
  • The study investigates the effectiveness of mean propulsive velocity (MPV) as an indicator of neuromuscular fatigue during strength training in Paralympic powerlifting athletes.
  • Two training methods were compared: traditional (TRAD) and eccentric (ECC), with findings showing that TRAD resulted in minimal performance loss (~5%) and no significant decline in MPV, while ECC led to a more considerable performance loss (~12%).
  • The results imply that MPV may not be a reliable measure of neuromuscular fatigue in this context, suggesting it is more useful for monitoring training volume rather than fatigue levels.

Statement Of Problem: Computer-aided design and manufacturing (CAD/CAM) have been increasingly used to enhance the patient and clinician experiences with removable complete dentures (CDs). Yet, evidence from systematic reviews is lacking to validate the clinical significance of these digital prostheses.

Purpose: The purpose of this systematic review was to compare CAD/CAM CDs with the traditional ones in terms of patient and clinician-reported outcomes, post-insertion adjustment visits and costs.

Introduction: The present review aimed to systematically summarize the impacts of environmental enrichment (EE) on cerebral oxidative balance in rodents exposed to normal and unfavorable environmental conditions.

Methods: In this systematic review, four databases were used: PubMed (830 articles), Scopus (126 articles), Embase (127 articles), and Science Direct (794 articles). Eligibility criteria were applied based on the Population, Intervention, Comparison, Outcomes, and Study (PICOS) strategy to reduce the risk of bias.

Article Synopsis
  • The study aimed to understand how the order of performing drop jumps (DJ) and dynamic stretching (DS) affects sprinting performance among competitive athletes.
  • Thirteen male athletes participated in three different conditions (DS+DJ, DJ+DS, and control) after a standard warm-up, and their sprinting performance over 40 meters was measured.
  • Results indicated that doing dynamic stretching before drop jumps improved final acceleration during sprinting, while the opposite order negatively impacted initial acceleration; lower-powered athletes gained the most benefit from this approach.

This systematic review aims to evaluate the influence of environmental enrichment (EE) on oncological factors in experimental studies involving various types of cancer models. A comprehensive search was conducted in three databases: PubMed (161 articles), Embase (335 articles), and Scopus (274 articles). Eligibility criteria were applied based on the PICOS strategy to minimize bias.

The present systematic review aimed to discuss the impacts of different triathlon protocols on the level of pro and anti-inflammatory cytokines, as well as biomarkers related to the performance of healthy individuals. Four databases [PubMed (28 articles), Scopus (24 articles), Science Direct (200 articles), and SPORT Discus (1101 articles) were assessed. The eligibility criteria were applied, and the selected articles were used in the peer review, independently, as they were identified by March 2022.

Purpose: To review the literature on CAD/CAM removable complete and partial dentures regarding patient- and clinician-reported outcomes.

Materials And Methods: We performed an electronic search of the Cochrane Central Register of controlled trials (CENTRAL), MEDLINE (Ovid), EMBASE, Scopus, and Web of Science databases (last update: March 2023). All clinical trials or observational studies investigating CAD/ CAM removable dentures (conventional or implant-retained) were included.

Article Synopsis
  • Drop jumps (DJ) are commonly used in training to enhance long jump performance, but their immediate effects as a Conditioning Activity (CA) had not been studied before.
  • This study tested eleven male long jumpers to see how performing five drop jumps just before competition attempts affected their jump distances.
  • Results showed that jumps performed after DJ had greater distances and take-off velocities than those without the conditioning, suggesting that DJs can significantly improve long jump performance through increased vertical take-off velocity.

This study evaluated surface properties and adhesion/biofilm formation by Candida albicans on 3D printed denture base resins used in 3D printing. Disc-shaped specimens (15 mm x 3 mm) of two 3D-printed resins (NextDent Denture 3D+, NE, n = 64; and Cosmos Denture, CO, n = 64) and a heat-polymerized resin (Lucitone 550, LU, control, n = 64) were analyzed for surface roughness (Ra μm) and surface free energy (erg cm-2). Microbiologic assays (90-min adhesion and 48-h biofilm formation by C.

Background: Strength training is a complex task, as it requires a combination of many variables. In paralympic powerlifting (PP) asymmetries for the evaluation of activation, and static force indicators have been increasingly studied.

Objective: To investigate the asymmetries in the strength and muscle activation indicators, before and after a training session of PP athletes.

We purpose to determine the nationality of the European middle-distance athletes under 18 years (U18) and under 20 years (U20) during the last decade, to verify the participation trend for each country, and to assess whether the place of competition can be associated with the athletes ranking position. The sample comprised 902 European male runners, ranked among the best finishers from 2009 to 2020. The athletes were divided into two categories ( ​= ​266; and  ​= ​636) of two distances ( ​= ​397;  ​= ​505).

Endoplasmic reticulum stress (ER stress) affects many tissues and contributes to the development and severity of chronic diseases. In contrast, regular physical exercise (PE) has been considered a powerful tool to prevent and control several chronic diseases. The present systematic review aimed to evaluate the impact of different PE protocols on ER stress markers in central and peripheral tissues in rodents.

Purpose: The objective of this study was to compare patient-reported outcomes (PROs) of peri‑implant soft tissue inflammation and aesthetics around single-tooth implants in the anterior maxillary region with three different implant-abutment interface designs.

Methods: Participants were randomized to one of three different types of implant-abutment interface designs [Conical (CI), flat-to-flat (FI), and Platform Switched (PS)]. Implants and provisional crowns with prefabricated titanium abutments were placed 5 months following extraction and/or ridge augmentation.
