Abstract

The continuing advancement of new technologies is making available novel sources of occurrence data, such as photo‐sharing platforms. Using three Iberian Argiope spider species as models, this study aimed to compare the quality of three data sources – existing scientific literature, a biodiversity‐focused photo‐sharing citizen science project, and a photo‐sharing social network – and the results derived from niche and distribution analyses.
Data sources were compared in terms of sample size, spatial clustering, and coverage, degree of climatic niche completeness, and in their consistency in the characterisation of response curves. Possible biases towards big cities and protected natural areas were identified, and species distribution models were parameterised and compared.
Photo records provided the largest number of occurrences, whereas data from scientific literature showed the worst spatial coverage. Records from the citizen science project yielded the highest degree of niche completeness. All data sources showed some bias towards big cities and protected areas. Data from existing scientific literature yielded the worst range representations and, accordingly, the most different distribution models, whereas the models based on two photo‐vouchered sources were very similar.
Range and niche analyses using records from different sources may yield disparate results. Occurrence data from existing scientific literature may not be enough to develop robust niche analyses nor to characterise recent range changes of poorly studied taxa. Photo‐sharing platforms provide updated chorological information and have the potential to increase sample sizes dramatically, which is an important data property in distribution and niche modelling.

AbstractIn this work, three different commercial lithium silicate (LS) glass‐ceramics for computer aided design/computer aided machining systems, CeltraDuo‐Dentsply (LS‐C), E‐MaxCAD‐Ivoclar (LS‐E), and Suprinity‐Vita (LS‐S), were comparatively characterized. Following the protocols recommended by the manufacturers, the glass‐ceramics were heat‐treated under low vacuum and characterized by X‐ray diffraction, scanning electron microscopy, hardness, fracture toughness, Young's modulus, and flexural strength. Rietveld refinement indicated that the materials “as‐received” present mostly amorphous phase and Li2SiO3 as secondary crystalline phase in LS‐E and LS‐S specimens, while LS‐C specimens also present Li2Si2O5 and Li3PO4 as crystalline phases. All “as‐received” glass‐ceramics present hardness, fracture toughness, and Young's modulus of around 647‐678 HV, 1.15‐1.40 MPa.m1/2, and 82‐92 GPa, respectively. After heat treatment, the LS‐C and LS‐S specimens presented decreasing of amorphous phase associated to Li2SiO3 and Li2Si2O5 grains with low aspect ratio, while LS‐E indicates a reduction of amorphous phase and Li2Si2O5 elongated grains. Fracture toughness and Young's modulus increase about 10% due to the crystallization of residual amorphous phase for all materials. Moreover, crystallographic and microstructural characteristics are responsible for the higher flexural strength of LS‐E (327 MPa), regarding LS‐C and LS‐S. However, the glass‐ceramics LS‐E present lower Weibull modulus (m = 5.4) comparatively to LS‐C (m = 9) and LS‐S (m = 6).

ObjectiveTo estimate the conditional biochemical recurrence‐free probability and to develop a predictive model according to the disease‐free interval for men with clinically localized prostate cancer treated with minimally invasive radical prostatectomy.MethodsThe study population consisted of 3576 consecutive patients who underwent laparoscopic radical prostatectomy and 2619 men treated with robotic radical prostatectomy in the past 15 years at Institute Mutualiste Montsouris, Paris, France. Biochemical recurrence was defined as serum prostate‐specific antigen ≥0.2 ng/dL. Univariable and multivariable survival analyses were carried out to identify the prognostic factors for overall free‐of‐biochemical recurrence probability and conditional survival with respect to the years from surgery without recurrence. A detailed nomogram for the static and dynamic prognosis of biochemical recurrence was developed and internally validated.ResultsThe median follow‐up period was 8.49 years (interquartile range 4.01–12.97), and 1148 (19%) patients experienced biochemical recurrence. Significant variables associated with biochemical recurrence in the multivariable model included preoperative prostate‐specific antigen, positive surgical margins, extracapsular extension, pathological Gleason ≥4 + 3 and laparoscopic surgery (all P < 0.001). Conditional survival probability decreased with increasing time without biochemical recurrence from surgery. When stratified by prognosis factors, the 5‐ and 10‐year conditional survival improved in all cases, especially in men with worse prognosis factors. The concordance index of the nomogram was 0.705.ConclusionsConditional survival provides relevant information on how prognosis evolves over time. The risk of recurrence decreases with increasing number of years without disease. An easy‐to‐use nomogram for conditional survival estimates can be useful for patient counseling and also to optimize postoperative follow‐up strategies.

ObjectiveTo evaluate the change in the operated parenchymal volume during robot‐assisted partial nephrectomy limited to the enucleation technique, and to analyze the predictors of decrease in operated parenchymal volume, including the tumor contact surface area.MethodsThe study included 135 patients who underwent robot‐assisted partial nephrectomy for T1 renal tumors using the enucleation technique. Measurements of the parenchymal volume, tumor volume and contact surface area were obtained in the venous phase on enhanced computed tomography. All measurements, including volumetric and renal function analysis, were carried out <2 months before and 6 months after surgery.ResultsThe mean age of included participants was 56 years, and the mean tumor size was 33 mm. The mean tumor volume was 26 cc, and the mean contact surface area was 22 cm2. In the complete cohort, the mean preoperative and postoperative normal parenchymal volumes of the operated kidney were 158 and 141 cc, respectively. The mean change in parenchymal volume of the operated kidney was −10%. In contrast, the mean change in global estimated glomerular filtration was just −4.0%. Univariate analysis showed that the RENAL nephrometry score, contact surface area, tumor volume and warm ischemia time were associated with the change in the operated kidney parenchymal volume. However, in the multivariate analysis, a large contact surface area was the only independent predictor of decreased operated parenchymal volume <10 cm3.ConclusionContact surface area is a strong predictor of the decrease in the parenchymal volume in the operated kidney during robot‐assisted partial nephrectomy carried out using the enucleation technique for T1 renal tumors.

AbstractSelf‐healing capability in wet oxygen atmospheres is the key issue for long term service of SiC/SiC composites in aero‐engines. Polymer derived SiBCN ceramic (PDC SiBCN) was introduced into SiC fiber reinforced SiC as a self‐healing component to obtain SiC/(SiC‐SiBCN)x composites by a newly developed method, namely chemical vapor infiltration combined with polymer infiltration online pyrolysis (CVI + PIOP) process. The weight loss behavior and three‐point bending performance of the samples under different temperatures (1200, 1300 and 1400°C) and different wet oxygen partial pressures were tested up to 100 hours to demonstrate the oxidation behavior of the samples in wet oxygen environments. According to these tests, the antioxidant capacities of samples prepared from different preforms were compared. It has been found that the 2D plain weave samples with higher density have the best resistance to wet oxygen corrosion while the 2D plain weave samples have the worst resistance to wet oxidation and the antioxidant capacities of 2D satin weave samples is between them.

AbstractRecently, nanostructured thermal barrier coatings have received considerable attention because of some superior properties in comparison with their conventional counterpart. In this study, nanostructured 8 wt% yttria‐stabilized zirconia (n‐YSZ) coatings were deposited by atmospheric plasma spraying, and the degradation behavior caused by molten calcium‐magnesium‐aluminon‐silicate (CMAS) attack was investigated. Results showed that the thermo‐chemical reaction product between CMAS and YSZ (both powders and coatings) is different with the change of CMAS content. At low CMAS concentration, a cubic phase is generated by the diffusion of Ca into YSZ grains. As compared to the conventional YSZ, less C‐ZrO2 is detected for n‐YSZ. When CMAS reaches a certain concentration (eg 15 mg/cm2), disruptive phase transformation from tetragonal to monoclinic will occur and the reaction is more readily for n‐YSZ. Two different chemical reaction mechanisms governing the CMAS content effect were proposed. It should be noted that the nanozone in the coatings plays an important role in the CMAS degradation process, which enhances CMAS infiltration rate and accelerates the chemical reaction, leading to a poor CMAS resistance of the nanostructured coating than that of the conventional counterpart.

AbstractBa0.875Ca0.125Ti0.95Sn0.05O3 (BCT‐Sn) was examined for photocatalytic, piezocatalytic, and piezo‐photocatalytic effects. BCT‐Sn powder was poled through corona poling and it was found that poling induces significant impact on photocatalysis. This material was also able to degrade dye (Methylene blue) using poled powder under ultrasonication (piezocatalysis). There was a remarkable effect in dye degradation which is a clear indication of the importance of piezocatalytic behavior in catalytic reactions. Moreover, the piezo‐photocatalytic effect (piezocatalysis + photocatalysis) was also investigated. Results suggested an enormous scope of ferroelectric materials in the field of catalysis.

AbstractObjectivesThe purpose of this longitudinal study was to evaluate the relationship between beta‐3 adrenergic receptor polymorphism and environmental factors such as smoking on periodontal disease by considering effect modification.Materials and MethodsA total of 294 subjects who participated in all follow‐up surveys over the 6‐year study period were analysed. After dividing subjects into tertiles according to the number of years exposed to smoking, we conducted Poisson regression analysis to compare the incidence rate ratio (IRR) for periodontal disease events during the 6‐year study period with beta‐3 adrenergic receptor genotype (1: Arg allele carriers, 2: Arg allele non‐carriers) for each tertile adjusted for other four variables.ResultsThe number of years exposed to smoking (mean ± standard deviation) for the 1st, 2nd and 3rd tertiles was 0 ± 0, 20.1 ± 9.1 and 45.3 ± 7.7 years, respectively. The IRRs ± SE were 0.89 ± 0.08 (p = 0.218) for the 1st tertile, 1.93 ± 0.36 (p < 0.001) for the 2nd tertile and 2.56 ± 0.23 (p < 0.001) for the 3rd tertile.ConclusionThere was a clear dose–response relationship between beta‐3 adrenergic receptor genotype and periodontal disease progression based on the number of years exposed to smoking.

AbstractAims/IntroductionIncretin hormone glucose‐dependent insulinotropic polypeptide/gastric inhibitory polypeptide (GIP) plays a key role in high‐fat diet‐induced obesity and insulin resistance. GIP is strongly secreted from enteroendocrine K cells by oil ingestion. G protein‐coupled receptor (GPR)120 and GPR40 are two major receptors for long chain fatty acids, and are expressed in enteroendocrine K cells. In the present study, we investigated the effect of the two receptors on oil‐induced GIP secretion using GPR120‐ and GPR40‐double knockout (DKO) mice.Materials and MethodsGlobal knockout mice of GPR120 and GPR40 were crossbred to generate DKO mice. Oral glucose tolerance test and oral corn oil tolerance test were carried out. For analysis of the number of K cells and gene expression in K cells, DKO mice were crossbred with GIP‐green fluorescent protein knock‐in mice in which visualization and isolation of K cells can be achieved.ResultsDouble knockout mice showed normal glucose‐induced GIP secretion, but no GIP secretion by oil. We then investigated the number of K cells and gene characteristics in K cells isolated from GIP‐green fluorescent protein knock‐in mice. Deficiency of both receptors did not affect the number of K cells in the small intestine or expression of GIP messenger ribonucleic acid in K cells. Furthermore, there was no significant difference in the expression of the genes associated with lipid absorption or GIP secretion in K cells between wild‐type and DKO mice.ConclusionsOil‐induced GIP secretion is triggered by the two major fatty acid receptors, GPR120 and GPR40, without changing K‐cell number or K‐cell characteristics.

AbstractAimThe aim of the present study was to evaluate the marginal and internal fit of zirconium fixed partial denture using different impression techniques.MethodsA Nissin Typodont model, including maxillary central incisor and canine with missing lateral incisor, was selected for the present study. Thirty zirconium frameworks were fabricated following three impression techniques (N = 10), conventional silicone impression (group C), scanned dental impression (group S), and Trios 3 (3Shape) intraoral scanner (group T). An extra‐fine milling strategy was applied.ResultsGroup T had the smallest discrepancy compared to groups C (P = 0.006) and S (P = 0.052) at the marginal level, whereas it was larger at the incisal tip. Discrepancies in group T were smaller than group C (P = 0.004) when measured at the axial walls, and smaller than group S (P = 0.045) when measured at the chamfer area for the central teeth only. Samples in group T showed a greater percentage of equally extended restorations (52.5%), while other groups were mainly underextended (group C: 63.7%, group S: 68.8%).ConclusionBetter adaptation was achieved with the intraoral scanner group, except at the incisal tip. Conventional and scanned impressions revealed a greater percentage of underextended restorations.

AbstractMicroRNAs (miRNAs) play important roles in rice response to Magnaporthe oryzae, the causative agent of rice blast disease. Studying the roles of rice miRNAs is of great significance for the disease control. Osa‐miR167d belongs to a conserved miRNA family targeting auxin responsive factor (ARF) genes that act in developmental and stress‐induced responses. Here, we show that Osa‐miR167d plays a negative role in rice immunity against M. oryzae by suppressing its target gene. The expression of Osa‐miR167d was significantly suppressed in a resistant accession at and after 24 h post inoculation (hpi), however, its expression was significantly increased at 24 hpi in the susceptible accession upon M. oryzae infection. Transgenic rice lines over‐expressing Osa‐miR167d were highly susceptible to multiple blast fungal strains. By contrast, transgenic lines expressing a target mimicry to block Osa‐miR167d enhanced resistance to rice blast disease. In addition, knocking out the target gene ARF12 led to hyper‐susceptibility to multiple blast fungal strains. Taken together, our results indicate that Osa‐miR167d negatively regulate rice immunity to facilitate the infection of M. oryzae by downregulating ARF12. Thus, Osa‐miR167d‐ARF12 regulatory module could be valuable in improvement of blast‐disease resistance.
Mitochondria‐coupled glucose phosphorylation develops after birth to modulate H2O2 release and calcium handling in rat brain

Published: April 2019

AbstractThe adult brain is a high‐glucose and oxygen‐dependent organ, with an extremely organized network of cells and large energy‐consuming synapses. To reach this level of organization, early stages in development must include an efficient control of cellular events and regulation of intracellular signaling molecules and ions such as hydrogen peroxide (H2O2) and calcium (Ca2+), but in cerebral tissue, these mechanisms of regulation are still poorly understood. Hexokinase (HK) is the first enzyme in the metabolism of glucose and, when bound to mitochondria (mtHK), it has been proposed to have a role in modulation of mitochondrial H2O2 generation and Ca2+ handling. Here, we have investigated how mtHK modulates these signals in the mitochondrial context during postnatal development of the mouse brain. Using high‐resolution respirometry, western blot analysis, spectrometry and resorufin, and Calcium Green fluorescence assays with brain mitochondria purified postnatally from day 1 to day 60, we demonstrate that brain HK increases its coupling to mitochondria and to oxidative phosphorylation to induce a cycle of ADP entry/ATP exit of the mitochondrial matrix that leads to efficient control over H2O2 generation and Ca2+ uptake during development until reaching plateau at day 21. This contrasts sharply with the antioxidant enzymes, which do not increase as mitochondrial H2O2 generation escalates. These results suggest that, as its use of glucose increases, the brain couples HK to mitochondria to improve glucose metabolism, redox balance and Ca2+ signaling during development, positioning mitochondria‐bound hexokinase as a hub for intracellular signaling control.

AbstractAimTo evaluate the clinical application of moist wound dressings in wound care for patients with the tracheostomy.BackgroundTracheostomy patients may suffer from many complications. Moist dressings have been proposed to lower complication rates for patients with the tracheostomy.DesignA Preferred Reporting Items for Systematic Reviews and Meta‐analyses (PRISMA) checklist‐guided meta‐analysis of randomised and controlled clinical trials.MethodIn this meta‐analysis, two reviewers independently searched PubMed, EMBASE, Cochrane Library, Web of Science, CNKI and Wanfang databases for controlled clinical trials (CCTs) comparing the use of moist dressings and gauze for tracheostomy patients. The reviewers screened studies according to the inclusion criteria and extracted data from published reports independently. The outcome of site infection and pressure ulcer incidence, the frequency of dressing changes and wound closing time were evaluated by random‐effects or fixed‐effects meta‐analysis.ResultsAfter the screening, ten studies including 1,220 participants were eligible for analysis. The result showed that the incidence of site infection and pressure ulcer was significantly reduced in the moist dressings group compared with the gauze group. Moist dressings were also associated with significant reductions in the frequency of dressing changes and wound closing time. These results were assessed as moderate‐ to low‐quality evidence.ConclusionMoist dressings seem to be beneficial to tracheostomy patients, giving a lower incidence of site infection and pressure ulcers as well as shorter wound closing times and lower dressing change frequency. More high‐quality trials are needed to support this finding.Relevance to clinical practiceThe findings offer clinicians an assessment of and evidence for the efficacy of moist dressings, which may be a superior option for patients with a tracheotomy.

ABSTRACTBACKGROUND AND PURPOSEAneurysm hemodynamics play an important role in aneurysm growth and subsequent rupture. Within the available hemodynamic characteristics, particle residence time (PRT) is relatively unexplored. However, some studies have shown that PRT is related to thrombus formation and inflammation. The goal of this study is to evaluate the association between PRT and aneurysm rupture and morphology.METHODSWe determined the PRT for 113 aneurysms (61 unruptured, 53 ruptured) based on computational fluid dynamic models. Virtual particles were injected into the parent vessel and followed during multiple cardiac cycles. PRT was defined as the time needed for 99% of the particles that entered an aneurysm to leave the aneurysm. Subsequently, we evaluated the association between PRT, rupture, and morphology (aneurysm type, presence of blebs, or multiple lobulations).RESULTSPRT showed no significant difference between unruptured (1.1 seconds interquartile range [IQR .39‐2.0 seconds]) and ruptured aneurysms (1.2 seconds [IQR .47‐2.3 seconds]). PRT was influenced by aneurysm morphology. Longer PRTs were seen in bifurcation aneurysms (1.3 seconds [IQR .54‐2.4 seconds], P = .01) and aneurysms with blebs or multiple lobulations (1.92 seconds [IQR .94‐2.8 seconds], P < .001). Four of five partially thrombosed aneurysms had a long residence time (>1.9 seconds).CONCLUSIONSOur study shows an influence of aneurysm morphology on PRT. Nevertheless, it suggests that PRT cannot be used to differentiate unruptured and ruptured aneurysms.
