AbstractAn expert recommendation conference was conducted to identify factors associated with adverse events during laparoscopic cholecystectomy (LC) with the goal of deriving expert recommendations for the reduction of biliary and vascular injury. Nineteen hepato‐pancreato‐biliary (HPB) surgeons from high‐volume surgery centers in six countries comprised the Research Institute Against Cancer of the Digestive System (IRCAD) Recommendations Group. Systematic search of PubMed, Cochrane, and Embase was conducted. Using nominal group technique, structured group meetings were held to identify key items for safer LC. Consensus was achieved when 80% of respondents ranked an item as 1 or 2 (Likert scale 1–4). Seventy‐one IRCAD HPB course participants assessed the expert recommendations which were compared to responses of 37 general surgery course participants. The IRCAD recommendations were structured in seven statements. The key topics included exposure of the operative field, appropriate use of energy device and establishment of the critical view of safety (CVS), systematic preoperative imaging, cholangiogram and alternative techniques, role of partial and dome‐down (fundus‐first) cholecystectomy. Highest consensus was achieved on the importance of the CVS as well as dome‐down technique and partial cholecystectomy as alternative techniques. The put forward IRCAD recommendations may help to promote safe surgical practice of LC and initiate specific training to avoid adverse events.
Oogenesis in the viviparous phoronid, Phoronis embryolabi
Authors: Temereva Elena N. 
Published: October 2017

AbstractThe study of gametogenesis is useful for phylogenetic analysis and can also provide insight into the physiology and biology of species. This report describes oogenesis in the Phoronis embryolabi, a newly described species, which has an unusual type of development, that is, a viviparity of larvae. Phoronid oogonia are described here for the first time. Yolk formation is autoheterosynthetic. Heterosynthesis occurs in the peripheral cytoplasm via fusion of endocytosic vesicles. Simultaneously, the yolk is formed autosynthetically by rough endoplasmic reticulum in the central cytoplasm. Each developing oocyte is surrounded by the follicle of vasoperitoneal cells, whose cytoplasm is filled with glycogen particles and various inclusions. Cytoplasmic bridges connect developing oocytes and vasoperitoneal cells. These bridges and the presence of the numerous glycogen particles in the vasoperitoneal cells suggest that nutrients are transported from the follicle to oocytes. Phoronis embryolabi is just the second phoronid species in which the ultrastructure of oogenesis has been studied, and I discuss the data obtained comparing them with those in Phoronopsis harmeri. Finally, I discuss the distribution of reproductive patterns across both, molecular and morphological phylogenetic trees in Phoronida proving that parental care has evolved independently several times in this phylum.

ABSTRACTAir trajectories are useful tools to investigate the airflow and transport of substances released into the atmosphere. Web‐based models are widely used to calculate trajectories reaching places that are being studied. This article considers 6 years of air trajectories as of October 2010 together with CO2 and CH4 concentrations. A bivariate smoothing function that employs the radial distance and direction of the trajectory to the measuring site was used to form trajectory groups from the minima of this function. Varied radial and angular windows were assayed to investigate the behaviour of the smoothing function. Curves associated with the number of minima were L‐shaped and the windows selected corresponded to the ‘knee’ of the curves. Seven trajectory groups were considered to observe the response of the procedure against the radial distance and the direction. Seasonal evolution revealed the greatest radial extent for winter and the lowest for summer. Moreover, trajectories from the Atlantic Ocean were the most frequent. CO2 and CH4 concentrations were detrended using a linear function, and average trends were 2.34 and 0.0085 ppm year−1, respectively. Annual cycles of detrended concentrations were very soft and were linked to the site's ecosystem. CO2 presented one maximum in spring linked to substantial vegetation growth, and one minimum in summer, when vegetation dies and dispersion is maximum. CH4 maximum was observed in winter although the minimum was found in summer and attributed to oxidation with the hydroxyl radical in the troposphere and to dispersion in this season. Analysis of concentration trends for the groups proposed revealed the opposite behaviour of both gases in summer. Finally, maximum CO2 concentrations were marked by trajectories from North Africa affected by nearby cities, whereas minimum concentrations for both gases were noticeable for trajectories from the ocean in summer.
Hip abductor strength and fatigue are associated with activity levels more than 1 year after total hip replacement

Published: October 2017

ABSTRACTDespite improvements in pain and function, people who undergo total hip arthroplasty (THR) may not always return to desired levels of physical activity (PA). The factors associated with low activity levels are not fully understood. Abductor weakness and fatigue have both been proposed as factors that limit activity in older adults or people with hip osteoarthritis, but have not been investigated after THR. We hypothesized that abductor weakness and fatigue are associated with lower activity levels in people who have undergone a THR and that fatigue mediates the association between abductor strength and activity. We evaluated 16 subjects (24 ± 10 months post‐THR; age 56.8 ± 8.4 yrs; BMI 31 ± 7 kg/m2). Fatigue was assessed using the PROMIS fatigue short‐form 7a. Peak isometric hip abductor torque was assessed using a dynamometer with subjects in a sidelying position. We assessed activity level using the UCLA activity score. We used Pearson correlations to explore the associations among the variables. Next we used a three‐step linear regression procedure to test whether or not fatigue acted as a mediator between abductor torque and UCLA activity scores. Higher abductor torque was associated with less fatigue (R2 = 0.275; p = 0.037) and with higher UCLA scores (R2 = 0.488, p = 0.003). Higher fatigue was associated with lower UCLA scores (R2 = 0. 307, p = 0.017), however there was no evidence of mediation. This suggests that addressing both abductor strength and fatigue may increase physical activity. Statement of Clinical Significance: Fatigue and abductor weakness should be evaluated in sedentary THR patients presenting for long‐term follow‐up. © 2017 Orthopaedic Research Society.

ABSTRACTAccurate assessment of femoral version is essential to the surgical treatment of lower extremity deformities, yet the ideal modality and technique to measure femoral version is controversial. This study explored two hypotheses: First, there is no difference in the accuracy of femoral version measurement from 2D CT, 2D MRI, and 3D biplanar radiography reconstructions compared to a 3D model created from CT. Second, there is a difference between the measured version from traditional axial sections of the proximal femur compared to femoral neck oblique sections for CT and MRI. Eight adult cadaver lower extremities underwent CT, MRI, and biplanar radiography. Femoral version measurements from the CT and MRI axial and oblique sections, as well as biplanar radiography reconstructions, were compared to 3D reconstructed models from CT. All five techniques underestimated femoral version compared to the 3D model, but none were statistically significantly different. Regarding the first hypothesis, all five techniques had excellent correlation (r > 0.81, p ≤ 0.01) with the 3D model. Concerning the second hypothesis, the CT and MRI version measurements in femoral neck oblique sections were greater by 5.4° and 1.4°compared to traditional axial sections, respectively. All five techniques across three modalities provided accurate assessment of femoral version, suggesting that the treating physician's choice of modality can be determined per individual patient, not on measurement accuracy. Clinical significance: In choosing a modality to determine femoral version, consider the advantages and disadvantages of each modality for the individual patient, using femoral neck oblique slices for CT and MRI when available. © 2017 Orthopaedic Research Society.

AbstractThe influence of probe laser chirp on hybrid femtosecond/picosecond pure‐rotational coherent anti‐Stokes Raman scattering is studied theoretically and experimentally. Experiments of N2(hybrid fs/ps pure‐rotational coherent anti‐Stokes Raman scattering) are carried out using an in‐house built second harmonic bandwidth compressor, results with different probe chirps of are reported. The experimental spectra are fitted with and without considering probe chirp. Including the chirp improves the fit to experimental spectra at all probe delays. The effect of probe pulse chirp is evaluated through a quantitative analysis of matching residuals.

Published: October 2017

AbstractWith the combined surface imprinting technique and immobilized template strategy, molecularly imprinted magnetic nanoparticles were successfully prepared and coupled with high‐performance liquid chromatography to selectively separate and determine gallic acid from the pomegranate rind. On the surface of carboxyl‐functionalized magnetic nanospheres, thin imprinting shells were formed using dopamine as monomer and crosslinker. The characteristics, polymerization conditions, and adsorption performances of the resultant nanomaterials were investigated in detail. In addition of good crystallinity, satisfactory magnetism, and uniform morphology of the obtained polymers, they had rapid binding kinetics, high adsorption capacity, and favorable reusability. In the mixed solution of four hydroxybenzoic acids, the prepared nanomaterials have an excellent selectivity to gallic acid with an imprinting factor of as high as 17.5. Therefore, the polymers have great potentials in specific extraction and enrichment of gallic acid from the complex natural resources.

ObjectivesThe traditional activation ratio divides contracted muscle thickness by resting muscle thickness while an abdominal draw‐in maneuver is performed during hook lying. Ultrasound imaging during function, such as standing or gait, or peak knee flexion in a single‐leg squat allows for further visualization of muscle activity. The goal of this study was to examine activation ratio calculations for transverse abdominis function in supine versus loaded conditions to determine the most informative normalization strategy for muscle activity based on thickness values.MethodsTransverse abdominis thickness was measured via ultrasound in 35 healthy participants under 4 different conditions. Comparisons were made between the traditional activation ratio tabletop, standing activation ratio (standing abdominal draw‐in maneuver thickness/quiet standing thickness), and functional activation ratio (single‐leg squat thickness/quiet standing thickness). Additionally, a cued activation ratio (single‐leg squat with cued abdominal draw‐in maneuver thickness/single‐leg squat thickness) during the single‐leg squat was obtained. Activation ratios of greater than 1.0 indicated that participants could activate the muscle during activity, and values were compared by analysis of variance.ResultsThe participants included 23 women and 12 men with a mean age ± SD of 21.3 ± 2.7 years, mass of 66.1 ± 14.4 kg, and height of 168.5 ± 10.1 cm. Activation ratios exceeded 1.0 in 94.3% for the traditional activation ratio, 85.7% for the standing activation ratio, 82.9% for the cued activation ratio, and 82.9% for the functional activation ratio. With groups defined as tabletop activated or not, the standing, cued, and functional activation ratios were all significantly different (all P < .05).ConclusionsNormalizing muscle thickness to the corresponding functional position quiet value provides a useful functional activation ratio and may help clinicians better understand the transverse abdominis role during complex functional tasks. Assessment techniques using various formulas for activation ratios reveal that the muscle functions differently during weight bearing compared to traditional measures.

ObjectivesTo evaluate the effect of preepiglottic space (PES) dissection in the endoscopic supraglottic laryngectomy (ESL).Study DesignA retrospective cohort study.MethodsWe retrospectively compared 15 patients who underwent ESL with 15 patients matched for clinical stage who underwent open partial horizontal laryngectomy (OPHL).The functional outcomes were assessed in terms of hospital stay; need for nasal feeding tube (NFT) and tracheostomy, as well as duration of their use; postoperative complications; aspiration pneumonia rates; voice quality; and dysphagia.ResultsAmong the ESL cases, combined dissection of the epiglottis and PES (type III) had a negative impact on functional outcomes. ESL patients experienced shorter hospital stays, as well as shorter use of NFT and tracheostomy, than patients who had OPHL.ConclusionCombined dissection of the epiglottis and PES (ESL type III) negatively affected functional outcome in patients undergoing ESL, a procedure generally related to significantly better functional outcomes than OPHL type I.Level of Evidence4.

Published: October 2017

AbstractVarious in vitro culture systems have been used to investigate the pathogenesis of age‐related macular degeneration (AMD). However, many still rely on oversimplified monolayer culture models. AMD is a complex disease, associated with the pathological changes to multiple structural components such as the Bruch's membrane, retinal pigment epithelium (RPE), and choroidal endothelial cells. This study aims to construct a novel 3D coculture model using the polycaprolactone (PCL)‐gelatin electrospun scaffold, with human RPE cells (hRPE) and primate choroidal cells (RF‐6A). Results from this study show that PCL‐gelatin scaffolds have a highly porous ultrastructure that supports the attachment, proliferation, differentiation, and migration of the hRPEs and choroidal endothelial cells. It is also demonstrated that the PCL‐gelatin 3D coculture model may be useful in exploring the molecular interplay between the hPRE and the choroidal endothelial cells, and their effects on growth factor modulation, which may be important in the pathogenesis of AMD.
Fermat's last theorem and Catalan's conjecture in weak exponential arithmetics

Published: October 2017

AbstractWe study Fermat's last theorem and Catalan's conjecture in the context of weak arithmetics with exponentiation. We deal with expansions of models of arithmetical theories (in the language ) by a binary (partial or total) function e intended as an exponential. We provide a general construction of such expansions and prove that it is universal for the class of all exponentials e which satisfy a certain natural set of axioms . We construct a model and a substructure with e total and (Presburger arithmetic) such that in both and Fermat's last theorem for e is violated by cofinally many exponents n and (in all coordinates) cofinally many pairwise linearly independent triples . On the other hand, under the assumption of ABC conjecture (in the standard model), we show that Catalan's conjecture for e is provable in (even in a weaker theory) and thus holds in and . Finally, we also show that Fermat's last theorem for e is provable (again, under the assumption of ABC in ) in “coprimality for e”.

AbstractThe purpose of this work was to optimize the pretreatment process of wheat straw by Polyporus brumalis_BRFM985 in order to improve carbohydrate accessibility for more efficient bioconversion. Indeed, there is growing demands to develop sustainable routes for lignocellulosic feedstocks valorization into value‐added products in energy, chemicals, materials, and animal feed fields. To be achieved, implementation of cheap and ecofriendly biomass pretreatment processes is necessary. In this frame, white rot basidiomycetes, well known for their ability to degrade lignin efficiently and selectively, are of great interest. The pretreatment of wheat straw by Polyporus brumalis_BRFM985 was performed in packed bed bioreactor and optimized using response surface methodology. The four pretreatment parameters optimized were metals addition (Cu, Mn, and Fe), time of culture, initial water content, and temperature. Multicriteria optimization highlighted that wheat straw pretreatment by Polyporus brumalis_BRFM985 in the presence of metals with high initial water content of 3.6 g H2O/g at 27°C for 15–16 days led to an improvement of carbohydrate accessibility with minimal matter loss.

AbstractStrain SIT6T was isolated from the fecal flora of a severely malnourished child as part of a broad “culturomics” study aiming to maximize the culture conditions for the in‐depth exploration of the human microbiota. An analysis of the 16S rRNA gene sequence showed that strain SIT6T shared 94.1% 16S rRNA gene sequence similarity with Bacillus thermoamylovorans DKPT (NR_029151), the phylogenetically closest type species. Colonies are creamy white, circular, 4–5 mm in diameter after cultivation at 37°C for 24 hr on 5% sheep blood‐enriched Colombia agar. Growth occurs at temperatures in the range of 25–56°C (optimally at 37°C). Strain SIT6T is a gram‐positive, facultative anaerobic rod and motile by means of peritrichous flagella and sporulating; it is catalase and oxidase positive. The 2,784,637‐bp‐long genome, composed of 16 contigs, has a G+C content of 35.19%. Of the 2,646 predicted genes, 2,572 were protein‐coding genes and 74 were RNAs. The major fatty acids are saturated species (15:0 iso, 16:0 and 17:0 anteiso). Of the 14 detected fatty acids, 11 are saturated, either linear or branched (iso and anteiso). Digital DNA–DNA hybridization (dDDH) estimation and average genomic identity of orthologous gene sequences (AGIOS) of the strain SIT6T against genomes of the type strains of related species ranged between 18.6% and 38.3% and between 54.77% and 65.50%, respectively. According to our taxonogenomics results, we propose the creation of Bacillus kwashiorkori sp. nov. that contains the type strain SIT6T (=CSUR P2452T, =DSM 29059T).

AbstractBackgroundCognitive dysfunction is common in progressive supranuclear palsy, but the influence of genetics on cognition in this disorder has not been well studied. The objective of this study was to investigate the effect of genes previously identified as risk alleles, including microtubule‐associated protein tau, myelin‐associated oligodendrocyte basic protein, eukaryotic translation initiation factor 2‐alpha kinase 3, and syntaxin 6, as well as apolipoprotein E, on cognitive function in progressive supranuclear palsy.MethodsThe sample was composed of 305 participants who met criteria for possible or probable progressive supranuclear palsy. Genetic information was determined by TaqMan genotyping assays. A neuropsychological battery was administered to all study participants. Measures included in the battery evaluated for general cognition, executive function, memory, attention, language, and visuospatial ability.ResultsCognition did not vary significantly between individuals homozygous or heterozygous for the microtubule‐associated protein tau H1 haplotype. However, cognition varied significantly at the subhaplotype level, with carriers of the microtubule‐associated protein tau rs242557/A allele, which marks the H1c subhaplotype, performing better than noncarriers on measures of general cognitive function, executive function, and attention. No associations were found for other genes.ConclusionsThe results of the current study indicate that variations in microtubule‐associated protein tau influence cognition in progressive supranuclear palsy. Although the H1c‐specific rs242557/A allele is a risk factor for progressive supranuclear palsy, carriers of this allele may exhibit better cognition than non‐carriers in patients with the atypical parkinsonian syndrome.
