Rationale: Current literature describes only 2 cases combining miniscrew-assisted rapid palatal expansion (MARPE) with lingual appliances. These cases require 2 impressions, 1 before and 1 after palatal expansion, to ensure accurate lingual appliance placement, potentially increasing treatment time and cost. This case report aimed to demonstrate a modified workflow of combining MARPE and lingual appliances in managing an adult patient with anteroposterior and transversal discrepancies, requiring only a single digital impression for both fabrication and positioning.

This challenge is further amplified in cases involving asymmetric space closure, such as those with a missing molar on one side and a premolar on the other, a scenario not yet documented in the literature. This case report presents the orthodontic-orthognathic management of an adult patient requiring space closure of asymmetric missing lower teeth.

This work addresses this challenge by employing a TiO grating to enhance light extraction and shape the emission of CsPbBr nanocrystal films. Angle-resolved photoluminescence (PL) demonstrated a 10-fold increase in emission intensity by coupling the Bloch resonances of the grating with the spontaneous emission of the perovskite NCs.

Hence, restoration of the anterior teeth has always been a significant concern for both dentists and patients worldwide. Indirect restoration using laminate veneers has revolutionized cosmetic dentistry by minimizing tooth preparation compared to full dental crowns.

This case report highlights the successful management of an adult female patient with bimaxillary protrusion, previously treated with a non-extraction approach. Treatment included lingual passive self-ligating appliances, premolar extractions, and mini-screws to reinforce anchorage.

However, the open bite in this case report was not a true open bite, as it resulted from the interferences between the maxillary second molars and mandibular retromolar bones. This case report aims to present the management of a true iatrogenic open bite with posterior teeth in centric occlusion, occurring after mandibular setback surgery.

The objectives of this study were to evaluate the marginal and internal fit of ceramic veneers manufactured with different CAD/CAM techniques. Materials and methods: A metal die was made by copying a prepared plastic maxillary central right incisor and scanned for designing a laminate veneer.

First, a robust classification model was developed from a dataset of 1,078 compounds with known Fyn kinase inhibitory activity, using the XGBoost algorithm. After that, molecular docking was performed between potential compounds identified from the QSAR model and Fyn kinase to assess their binding strengths and key interactions, followed by MD simulations.

The present article describes, in detail, the digital workflows for designing and fabricating 3D-printed lingual bracket indirect bonding trays and transfer jigs. Additionally, it aims to demonstrate the effectiveness of this approach in managing common orthodontic issues in adult patients.

Methods: Twenty-five patients in need of lingual orthodontic treatment were consecutively recruited. Bracket placement was performed on ideal setups, followed by fabricating indirect bonding trays through vacuum-forming on 3-dimensional printed models.
Progress toward Sustainable Development Goals for global access to safe sanitation is lagging significantly. In this Feature, we propose that misleading terminology leads to errors of categorization and hinders progress toward sanitation service provision in urban areas. Binary classifications such as "offsite/onsite" and "sewered/nonsewered" do not capture the need for "transport to treatment" or the complexity of urban sanitation and should be discarded.

Researchers are making great efforts to automatically detect and diagnose correctly diabetic retinopathy. Diabetic retinopathy includes five stages: no diabetic retinopathy, mild diabetic retinopathy, moderate diabetic retinopathy, severe diabetic retinopathy and proliferative diabetic retinopathy.

Data for parameterising these strategically important models are often scarce when rapid actions are required to change the course of an epidemic invading a new region. We introduce and test a flexible epidemiological framework for landscape-scale disease management of an emerging vector-borne pathogen for use with endemic and invading vector populations.

WSPs were introduced in Vietnam by the World Health Organization (WHO) in collaboration with the Ministry of Construction in 2006 and have been a mandatory requirement for municipal water supplies since 2012. Using a mixed-methods approach, we collected data on the perceived benefits and challenges of WSP implementation from 23 provincial water companies between August and November 2021.

The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global health concern. The development of vaccines with high immunogenicity and safety is crucial for controlling the global COVID-19 pandemic and preventing further illness and fatalities. Here, we report the development of a SARS-CoV-2 vaccine candidate, Nanocovax, based on recombinant protein production of the extracellular (soluble) portion of the spike (S) protein of SARS-CoV-2.

Little is known about video-assisted thoracoscopic surgery in the Nuss procedure (VATS-NUSS) and its postoperative outcomes in the resource-scarce conditions in clinical practice such as Vietnam. Available evidence in the literature was mostly reported from large institutions in developed countries. Hence, this study was conducted to review our initial large single-center experience in the use of the VATS-NUSS for patients with pectus excavatum (PE) within 5 years.

This case report describes the lingual orthodontic treatment of an adult skeletal Class III patient with mandibular deviation to the left side, lateral open bite, unilateral posterior crossbite, zero overbite and negative overjet. The lower incisors were already retroclined to compensate with the skeletal discrepancy.

Because of unique presentation, symmetric extraction could not be performed in the lower arch of this 34-year-old patient. She was treated with three premolar extractions and absolute anchorage with temporary anchorage devices for maximum retraction of upper anterior teeth.

The mode of action of the T6SS is similar to contractile phages: the contraction of a sheath structure pushes a tube topped by a spike into target cells. Effectors are loaded onto the spike or confined into the tube.

The importance of faecal sludge management is gaining recognition. However, methods are still lacking to reasonably estimate the quantities and qualities (Q&Q) that need to be managed, which makes the planning for and implementing of management solutions quite difficult. The objective of this study was to collect and analyse Q&Q of faecal sludge at a citywide scale, and to evaluate whether "SPA-DET" data (=> spatially analysable - demographic, environmental and technical) could then be used as predictors of Q&Q of faecal sludge.
