Maho Nakata, Tomomi Shimazaki
Large-scale molecular databases play an essential role in the investigation of various subjects such as the development of organic materials, in silico drug design, and data-driven studies with machine learning. We have developed a large-scale quantum chemistry database based on first-principles methods. Our database currently contains the ground-state electronic structures of 3 million molecules based on density functional theory (DFT) at the B3LYP/6-31G* level, and we successively calculated 10 low-lying excited states of over 2 million molecules via time-dependent DFT with the B3LYP functional and the 6-31+G* basis set...

Fernando Rojas-Vizcaya
A digital smile design was used to create an average smile and to develop a removable interim restoration for an edentulous patient with a high smile line and different bone levels in the maxilla. The interim restoration was used as a guide to perform bone sculpturing to create space for the biological width and to restore a monolithic zirconia implant-supported fixed restoration.

Studies of the last twenty years on the motor and premotor cortices of primates demonstrated that the motor system is involved in the control and initiation of movements, and in higher cognitive processes, such as action understanding, imitation, and empathy. Mirror neurons are only one example of such theoretical shift. Their properties demonstrate that motor and sensory processing are coupled in the brain. Such knowledge has been also central for designing new neurorehabilitative therapies for patients suffering from brain injuries and consequent motor deficits...

Design of Phase III trials for diabetic nephropathy currently requires patients at a high risk of progression defined as within three years of a hard end point (end-stage renal disease, 40% loss of estimated glomerular filtration rate, or death). To improve the design of these trials, we used natural history data from the Joslin Kidney Studies of chronic kidney disease in patients with diabetes to develop an improved criterion to identify such patients. This included a training cohort of 279 patients with type 1 diabetes and 134 end points within three years, and a validation cohort of 221 patients with type 2 diabetes and 88 end points...

Previous findings suggest immigrant patients have lower trust in their physicians, and perceive nonverbal communication differently compared to non-immigrant patients. We tested discrepancies in trust and the impact of non-verbal behavior between immigrants and non-immigrants in The Netherlands. Nonverbal communication of an oncologist was systematically varied in an experimental video vignettes design. Breast cancer patients (n = 34) and healthy women (n = 34) viewed one of eight video versions and evaluated trust and perceived friendliness of the oncologist...

Clinicians face significant challenges when placing single-tooth, implant-supported restorations in the esthetic zone. Understanding myriad factors, such as smile design, patient expectations, and hard- and soft-tissue responses, plays a vital role in achieving a predicable outcome. This article presents a case report demonstrating a minimally invasive approach, which combined immediate implant placement, hard- and softtissue augmentation, and immediate provisionalization in 1 visit.

It is widely accepted that all dentists should have a thorough understanding of the muscles involved in moving or stabilizing the mandible. However, there is still much discussion regarding the influence of the mandibular muscles on normal facial growth and dental development, as well as on orthodontic treatment and post-treatment stability. Potential patients with different underlying vertical muscle patterns will have differences in the expected directions of future mandibular growth, lateral profile shape, facial and arch widths and vertical occlusal relationships...

The aim of computational molecular design is the identification of promising hypothetical molecules with a predefined set of desired properties. We address the issue of accelerating the material discovery with state-of-the-art machine learning techniques. The method involves two different types of prediction; the forward and backward predictions. The objective of the forward prediction is to create a set of machine learning models on various properties of a given molecule. Inverting the trained forward models through Bayes' law, we derive a posterior distribution for the backward prediction, which is conditioned by a desired property requirement...

Obesity is one of the most provoking health burdens in the developed countries. One of the strategies to prevent obesity is the inhibition of pancreatic lipase enzyme. The aim of this study was to build QSAR models for natural lipase inhibitors by using the Monte Carlo method. The molecular structures were represented by the simplified molecular input line entry system (SMILES) notation and molecular graphs. Three sets - training, calibration and test set of three splits - were examined and validated. Statistical quality of all the described models was very good...

Medical and dental histories, clinical examination, study models, and photographs provide the data for a proper diagnosis and the treatment plan for esthetic dentistry. However, they do not offer all the information necessary to analyze the smile and create harmony with the lips and face without excessive intraoral adjustments. Dentolabial parameters vary according to lip dynamics and are influenced by both a static posed smile and a smile in motion as captured in video. This article describes a documentation protocol using smartphone videos to improve the analysis, smile design decisions, and elaboration of a 2D smile frame that will guide the 3D digital smile design project...

The program AceDRG is designed for the derivation of stereochemical information about small molecules. It uses local chemical and topological environment-based atom typing to derive and organize bond lengths and angles from a small-molecule database: the Crystallography Open Database (COD). Information about the hybridization states of atoms, whether they belong to small rings (up to seven-membered rings), ring aromaticity and nearest-neighbour information is encoded in the atom types. All atoms from the COD have been classified according to the generated atom types...

PURPOSE: Autophagy is an intracellular degradative system sensitive to hypoxia and exercise-induced perturbations to cellular bioenergetics. We determined the effects of low-intensity endurance-based exercise performed with blood-flow restriction (BFR) on cell signaling adaptive responses regulating autophagy and substrate metabolism in human skeletal muscle. METHODS: In a randomized cross-over design, nine young, healthy but physically inactive males completed three experimental trials separated by 1 week of recovery consisting of either a resistance exercise bout (REX: 4 × 10 leg press repetitions, 70% 1-RM), endurance exercise (END: 30 min cycling, 70% VO2peak), or low-intensity cycling with BFR (15 min, 40% VO2peak)...

Our goal was to evaluate how dental treatments under general anesthesia (GA) affect the quality of life by a prospective pair-matched design. Pediatric patients, who had received dental treatments under GA, were enrolled and were asked to complete the Early Childhood Oral Health Impact Scale (ECOHIS) before the treatment and 1 month after the treatment. To shield the observed impacts, a pair-matched control group was performed. Patients in the control group were also required to complete the ECOHIS at these different points in time...
