Universal Applicability of the Furlow Palatoplasty: Resident as Primary Surgeon in a Consecutive, Nonselective Series.

Questions persist regarding the general applicability of the Furlow palatoplasty technique, and thus, widespread adoption of its use has been uneven. This study describes a consecutive, nonselective series of primary Furlow palatoplasties. Highlighted is the unique fact that plastic surgical residents functioned as the primary surgeon for all steps of all procedures throughout the series.


Preliminary concurrent validity of the Fitbit-Zip and ActiGraph activity monitors for measuring steps in people with polymyalgia rheumatica.

Activity monitors provide objective measurements of physical activity, however, the accuracy of these devices in people with polymyalgia rheumatica (PMR) is unknown. Therefore, this study aimed to obtain preliminary evidence of the accuracy of two activity monitors and explore if clinical and gait-related factors altered device accuracy in people with PMR.

Prenatal sonographic diagnosis of a vitelline vein aneurysm.

We report a case of vitelline vein aneurysm detected at 23 weeks of gestation. Few postnatal cases of vitelline vein aneurysm have been reported; however, due to their similar appearances most of them were considered initially as umbilical vein dilatations. The accurate prenatal diagnosis of vitelline vein aneurysm and early postnatal surgical treatment are crucial steps to prevent postnatal obliterative extension of thrombosis that might cause severe neonatal morbidity.


Posture alteration as a measure to accommodate uneven ground in able-bodied gait.

Though the effects of imposed trunk posture on human walking have been studied, less is known about such locomotion while accommodating changes in ground level. For twelve able participants, we analyzed kinematic parameters mainly at touchdown and toe-off in walking across a 10-cm visible drop in ground level (level step, pre-perturbation step, step-down, step-up) with three postures (regular erect, ~30° and ~50° of trunk flexion from the vertical). Two-way repeated measures ANOVAs revealed step-specific ...

Enantiospecific total syntheses of (+)-Hapalindole H and (-)-12-epi-Hapalindole U.

Enantiospecific total syntheses of (+)-hapalindole H, (-)-12-epi-hapalindole U, formal synthesis of (+)-hapalindole Q and (+)-12-epi-fischerindole U isothiocyanate have been described. Key steps of our approach feature expedient, highly regio- and diastereoselective Lewis acid catalyzed Friedel-Crafts reaction of indole with cyclic allylic alcohols and intramolecular reductive Heck reaction. Efficiency of the synthetic route also relies on an alkynyl aluminate complex driven regioselective nucleophilic epox...

Synthesis of cis-5,5a,6,10b-Tetrahydroindeno2,1-bindoles through Palladium-Catalyzed Decarboxylative Coupling of Vinyl Benzoxazinanones with Arynes.

A novel palladium-catalyzed decarboxylative coupling reaction of vinyl benzoxazinanones with arynes which may feature an intramolecular nucleophilic attack of an amino group at the central carbon of π-allylpalladium intermediate has been developed. The cis-5,5a,6,10b-tetrahydroindeno[2,1-b]indoles were generated in moderate to good yields. One key to the success of the present reaction was to achieve comparable rates for the palladium-catalyzed decarboxylation and aryne formation steps.

Genome-Wide Association Mapping Analyses Applied to Polyamines.

Genome Wide Association Studies (GWAS) allow the use of natural variation to understand the genetics controlling specific traits. Efficient methods to conduct GWAS in plants have been reported. This chapter provides the main steps to conduct and analyse GWAS in Arabidopsis thaliana using polyamine levels as trait. This approach is suitable for the discovery of genes that modulate the levels of polyamines, and can be used in combination with different types of stress.

Inhibition of dengue virus infection by mannoside glycolipid conjugates.

Dengue virus (DENV), a mosquito-borne flavivirus, causes severe and potentially fatal symptoms in millions of infected individuals each year. Although dengue fever represents a major global public health problem, the vaccines or antiviral drugs proposed so far have not shown sufficient efficacy and safety, calling for new antiviral developments. Here we have shown that a mannoside glycolipid conjugate (MGC) bearing a trimannose head with a saturated lipid chain inhibited DENV productive infection. It showed...

Nickel-catalyzed coupling reaction of alkyl halides with aryl Grignard reagents in the presence of 1,3-butadiene: mechanistic studies of four-component coupling and competing cross-coupling reactions.

We describe the mechanism, substituent effects, and origins of the selectivity of the nickel-catalyzed four-component coupling reactions of alkyl fluorides, aryl Grignard reagents, and two molecules of 1,3-butadiene that affords a 1,6-octadiene carbon framework bearing alkyl and aryl groups at the 3- and 8-positions, respectively, and the competing cross-coupling reaction. Both the four-component coupling reaction and the cross-coupling reaction are triggered by the formation of anionic nickel complexes, wh...

Fully Disposable Manufacturing Concepts for Clinical and Commercial Manufacturing and Ballroom Concepts.

The availability and use of pre-sterilized disposables has greatly changed the methods used in biopharmaceuticals development and production, particularly from mammalian cell culture. Nowadays, almost all process steps from cell expansion, fermentation, cell removal, and purification to formulation and storage of drug substances can be carried out in disposables, although there are still limitations with single-use technologies, particularly in the areas of pretesting and quality control of disposables, bag...

The therapeutic 'make-over' of dementias-an introduction.

The online themed collection of 15 papers recently published provides an update on the advances of pharmacological and non-pharmacological interventions in dementia over the last 15 years. The published studies reflect the efficacy of the current anti-dementia treatments, preventive treatments of cardio and cerebrovascular incidents (known to be risk factors for dementia), alongside the use of antidepressant medication and non-pharmacological interventions for treatment of behavioural and psychopathological...

Ultra-compact bent multimode silicon waveguide with ultralow inter-mode crosstalk.

We propose and experimentally demonstrate a sharply bent multimode silicon waveguide by introducing a pair of mode converters. The principle of the multimode bend is based on the eigenmode conversion between straight and bent waveguides, and the particle swarm optimization is adopted to engineer the geometry. The device is fabricated on the standard silicon-on-insulator platform using one lithography/etching, and no additional steps are required. The measured results show that the insertion loss is

Total Synthesis and Absolute Configuration of Raputindole A.

The first total synthesis of the bisindole alkaloid raputindole A from the rutaceous plant Raputia simulans is reported. The key step is a Au(I)-catalyzed cyclization that assembles the cyclopenta[f]indole tricycle from a 6-alkynylated indoline precursor. The isobutenyl side chain was installed by Suzuki-Miyaura cross-coupling, followed by a regioselective reduction employing LiDBB. Starting from 6-iodoindole, the sequence needs nine steps and provided (±)-raputindole A in 6.6% overall yield. The absolute ...

Increased sediment loads cause non-linear decreases in seagrass suitable habitat extent.

Land-based activities, including deforestation, agriculture, and urbanisation, cause increased erosion, reduced inland and coastal water quality, and subsequent loss or degradation of downstream coastal marine ecosystems. Quantitative approaches to link sediment loads from catchments to metrics of downstream marine ecosystem state are required to calculate the cost effectiveness of taking conservation actions on land to benefits accrued in the ocean. Here we quantify the relationship between sediment loads ...

Molecular Confirmation of Frogs (Anura) as Hosts of Corethrellidae (Diptera) in the Southeastern United States.

Flies in the family Corethrellidae Edwards 1932 (Diptera) are known to be attracted to the mating calls of male frogs. For the first time, the hosts of corethrellids were identified to species by analyzing bloodmeals taken from resting female flies. A portion of the cytochrome b gene was amplified and sequenced from blood-engorged flies using vertebrate-specific primers. The flies were collected over 6 yr at two locations in the southeastern United States from resting boxes and natural resting sites (rodent...

A community based survey was conducted from -April to June 2015 using WHO NCD STEPS instrument versi...

Steps to Misdiagnosis: Dissecting an Emergency Visit.

Despite the common sense that we learn from our mistakes, an error is an unwelcome event when we deal with patients. Diagnostic error is common, costly, and the leading cause of malpractice litigation. Yet, errors occur occasionally in a lifetime of practice, and the consequences of these faults are significant for patients and physicians. If someone would have told me that I would miss a brain tumor in my first years of practice, in a patient presenting to my care with several cranial nerve signs, I would ...

Mechanism and cis/trans Selectivity of Vinylogous Nazarov-Type 6π Photocyclizations.

Vinylogous Nazarov-type cyclizations yield seven-membered rings from butadienyl vinyl ketones via a photochemical [6π] photocyclization followed by subsequent isomerization steps. The mechanism of this recently developed method was investigated using unrestricted DFT, SF-TDDFT, and CASSCF/NEVPT2 calculations, suggesting three different pathways that lead either to pure trans, pure cis, or mixed cis/trans configured products. Singlet biradicals or zwitterions occur as intermediates. The computational result...

An Alternative Approach to Study Primary Events in Neurodegeneration Using Ex Vivo Rat Brain Slices.

Despite numerous studies that attempt to develop reliable animal models which reflecting the primary processes underlying neurodegeneration, very few have been widely accepted. Here, we propose a new procedure adapted from the well-known ex vivo brain slice technique, which offers a closer in vivo-like scenario than in vitro preparations, for investigating the early events triggering cell degeneration, as observed in Alzheimer's disease (AD). This variation consists of simple and easily reproducible ste...

The General Adaptation Syndrome: A Foundation for the Concept of Periodization.

Recent reviews have attempted to refute the efficacy of applying Selye's general adaptation syndrome (GAS) as a conceptual framework for the training process. Furthermore, the criticisms involved are regularly used as the basis for arguments against the periodization of training. However, these perspectives fail to consider the entirety of Selye's work, the evolution of his model, and the broad applications he proposed. While it is reasonable to critically evaluate any paradigm, critics of the GAS have yet ...

Emission of categorized 50-kHz ultrasonic vocalizations in rats repeatedly treated with amphetamine or apomorphine: possible relevance to drug-induced modifications in the emotional state.

The emission of 50-kHz ultrasonic vocalizations (USVs) is increasingly emerging as a potential behavioral marker of the subjective effects that psychoactive drugs elicit in rats. However, multiple categories of 50-kHz USVs have been identified, which are thought to possess different behavioral significance. Besides, limited information is available on how psychoactive drugs affect the emission of categorized 50-kHz USVs. To further elucidate this issue, we evaluated the numbers of multiple categories of 50-...

Maintenance of the Maxillomandibular Position with Digital Workflow in Oral Rehabilitation: A Technical Note.

Prosthodontic oral rehabilitation procedures are time consuming and require efforts to maintain the confirmed maxillomandibular relationship. Several occlusal registrations and impressions are needed, and cross-mounting is performed to transfer the diagnostic wax-up to master working casts. The introduction of a digital workflow protocol reduces steps in the required process, and occlusal registrations with less deformation are used. The outcome is a maintained maxillomandibular position that is accurately ...
