The aminoquinoline derivatives, (R)- and (S)-2-phenyl-2-(quinolin-6-ylamino)ethan-1-ol (R-PEO and S-PEO), were synthesized by a tandem one-pot three-step CN coupling method where Smiles rearrangement was the key procedure. The selected compound R-PEO showed a significant fluorescence enhancement with a turn-on ratio over 98-fold and enabled the real time determination of proton concentration in acidic solution. The fluorescence intensity of R-PEO exhibited strong pH-dependent performance with a large Stokes shift (115nm) and responded linearly to minor pH change within the range of 3...

A new stereoselective arylative cyclopropanation process involving treatment of halogenated dienone systems in the presence of a Michael donor containing a nitro-aryl-sulfone has been developed. This transformation enables production of an arylated cyclopropane under mild conditions and occurs via a Michael-Smiles ring closure cascade process, reflecting the concepts of green chemistry and atom economy.

We examined the effects of social and cultural contexts on smiles displayed by children during gameplay. Eight-year-old Dutch and Chinese children either played a game alone or teamed up to play in pairs. Activation and intensity of facial muscles corresponding to Action Unit (AU) 6 and AU 12 were coded according to Facial Action Coding System. Co-occurrence of activation of AU 6 and AU 12, suggesting the presence of a Duchenne smile, was more frequent among children who teamed up than among children who played alone...

PURPOSE: The usefulness of mobile technology in supporting smoking cessation has been demonstrated, but little is known about how smartphone apps could best be leveraged. The purpose of this paper is to describe the program of research that led to the creation of a smoking cessation app for non-daily smokers, so as to stimulate further ideas to create "smart" smartphone apps to support health behavior change. METHOD: Literature reviews to evaluate the appropriateness of the proposed app, content analyses of existing apps, and smoking cessation sessions with non-daily smokers (n = 38) to inform the design of the app...

OBJECTIVE: To test the null hypothesis that there is no effect of esthetic perception of smiling profile in three different facial types by a change in the maxillary incisor inclination and position. MATERIALS AND METHODS: A smiling profile photograph with Class I skeletal and dental pattern, normal profile were taken in each of the three facial types dolichofacial, mesofacial, and brachyfacial. Based on the original digital image, 15 smiling profiles in each of the facial types were created using the FACAD software by altering the labiolingual inclination and anteroposterior position of the maxillary incisors...

Today, innovative restorative materials and techniques allow for minimally invasive prosthetic procedures, which are paramount to the preservation of hard and soft dental tissues. An integrated approach combining dental and esthetic medical therapies could be useful to improve the quality of life of patients, improving function, esthetics, and self-confidence. Oral esthetics depends on several variables, including tooth visibility and proportions as well as healthy gingival tissues. Proper integration between teeth and periodontal tissues plays an important role in esthetic success, which is mainly represented by an appealing smile...

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 SMILE-4 study showed that in patients with left ventricular dysfunction (LVD) following acute myocardial infarction (AMI), early treatment with zofenopril plus acetyl salicylic acid (ASA) is associated with an improved 1-year survival, free from death or hospitalization for cardiovascular (CV) causes, as compared to ramipril plus ASA. We now report on CV outcomes during a 5-year follow-up of the patients of the SMILE-4 study. 386 of the 518 patients completing the study (51.2%) could be tracked after the study end and 265 could be included in the analysis...

According to the literature, simple shapes induce emotional responses. Current evaluations suggest that humans consider angular shapes as "bad" and curvilinear forms as "good," but no behavioral data are available to support this hypothesis. Atypical development, such as autism spectrum disorder (ASD), could modify humans' perception of visual stimuli and thereby their emotional effect. This study assessed the effects of simple stimuli (i.e., jagged edges shape, disk, star, spiral, eye-like shape, and head character) on the emotional responses of different groups of humans...

PURPOSE: To investigate long-term changes in posterior corneal elevation after small incision lenticule extraction (SMILE). METHODS: Thirty-six eyes of 20 patients (7 male, 13 female) who underwent SMILE were recruited for this prospective consecutive study. The mean preoperative manifest spherical equivalent was -6.24 ± 1.47 diopters (D) (range: -3.88 to -8.75 D). Posterior corneal surfaces were measured by a Scheimpflug camera (Pentacam; Oculus Optikgeräte GmbH, Wetzlar, Germany) preoperatively and at 1 month, 6 months, 12 months, 2 years, and 3 years after surgery...

The kinamycin family of aromatic polyketide natural products contains an atypical angucycline ring system substituted with a diazo group. The enzymatic chemistry involved in constructing both of these structural features has been largely unexplored. Here we report the in vivo and in vitro production of seongomycin, a shunt product from this pathway, and stealthin C, a proposed biosynthetic precursor to the kinamycins. We show that a single enzyme, the flavin-dependent monooxygenase AlpJ, can generate these metabolites from N-acetyl-l-cysteine and l-cysteine, respectively, and that the synthesis of stealthin C likely proceeds via a nonenzymatic S-N-type Smiles rearrangement...

When observing emotional expressions, similar sensorimotor states are activated in the observer, often resulting in physical mimicry. For example, when observing a smile, the zygomaticus muscles associated with smiling are activated in the observer, and when observing a frown, the corrugator brow muscles. We show that the consistency of an individual's facial emotion, whether they always frown or smile, can be encoded into memory. When the individuals are viewed at a later time expressing no emotion, muscle mimicry of the prior state can be detected, even when the emotion itself is task irrelevant...

BACKGROUND: Evaluating health needs includes measures of the impact of state of health on the quality of life. This entails evaluating the psychosocial aspects of health. To achieve this, several tools for measuring the quality of life related to oral health have been developed. However, it is vital to evaluate the psychometric properties of these tools so they can be used in a new context and on a new population. The purpose of this study was to evaluate the reliability and validity of the Malagasy version of a questionnaire for studying the impacts of oral-dental health on daily activities (Oral Impacts on Daily Performance), and analyse the interrelations between the scores obtained and the oral health indicators...

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...
