Аннотация. Актуальность. Кератоконус — распространенное асимметричное и обычно двустороннее эктатическое заболевание роговицы, характеризующееся прогрессирующим выпячиванием роговицы, что приводит к снижению остроты зрения и ухудшению оптических свой­ств. Цель исследования. Оценить и сравнить зрительные, рефракционные и топографические результаты глаз с кератоконусом, после кросслинкинга роговичного коллагена в сочетании с имплантацией интрастромального роговичного сегмента в тот же день и без него в течение первых 12 месяцев. Материал и методы. Проанализировано 30 пациентов (38 глаз) с кератоконусом в возрасте 26,21 ± 6,97 (диапазон = 15–41) лет. В общей сложности 20 глаз были обработаны только кросслинкингом роговицы, а 18 глаз подверглись кросслинкингу роговичного коллагена в сочетании с одновременной имплантацией интрастромального роговичного сегмента с фемтосекундным сопровождением. Исходно, острота зрения, рефракция и топография роговицы (с использованием кератотопографа с Scheimpflug камерой) оценивались и сравнивались между двумя группами через 6 и 12 месяцев. Результаты. При средней продолжительности наблюдения 12,2 ± 0,50 (диапазон = 11–13) месяцев эффективным было как кросслинкинг роговичного коллагена, так и кросслинкинг роговичного коллагена с одновременной имплантацией интрастромального роговичного сегмента. Однако кросслинкинг роговичного коллагена плюс имплантация интрастромального роговичного сегмента привели к дополнительному улучшению некорригированной остроты зрения вдаль на 0,16 (95% доверительный интервал = от 0,01 до 0,32) логарифма минимального угла единиц разрешения (p = 0,035), цилиндрической степени на 1,16 дптр (95% доверительный интервал = от 0,25 до 2,06, p = 0,014) и сферический эквивалент на 1,40 дптр (95% доверительный интервал = от –2,71 до –0,08, p = 0,038) через 1 год. За период исследования ни в одной группе не было отмечено серьезных интраоперационных и послеоперационных осложнений. Заключение. Результаты наблюдения через год показывают, что кросслинкинг роговичного коллагена с одновременной комбинированной имплантацией интрастромального роговичного сегмента может привести к приросту визуального и рефракционного результата. Комбинированная процедура безопасна и заслуживает рассмотрения при лечении прогрессирующего кератоконуса для достижения лучшей зрительной реабилитации.

Predicting Phonological Awareness: The Roles of Mind-Wandering and Executive Attention
Authors: Yao Cheng , Jun Hu , Dai Guang-Song 
Published: June 2024

Purpose: This study aimed to investigate the predictive relationships between mind-wandering, executive attention, and phonological awareness. Methodology: A cross-sectional design was utilized, encompassing 300 participants recruited from a large urban university. Participants underwent assessments using the Comprehensive Test of Phonological Processing, Second Edition (CTOPP-2) for phonological awareness, the Mind-Wandering Questionnaire (MWQ) for mind-wandering, and the Attention Network Test (ANT) for executive attention. Data were analyzed through multiple linear regression using SPSS Version 27, assessing the predictive power of mind-wandering and executive attention on phonological awareness. Findings: The regression analysis demonstrated that mind-wandering and executive attention significantly predict phonological awareness, explaining 35% of its variance (R² = 0.35). Mind-wandering was found to have a negative impact on phonological awareness, with a standardized beta coefficient (β) of -0.22 and a p-value of <0.01, indicating that an increase in mind-wandering behaviors is associated with a decline in phonological processing skills. In contrast, executive attention positively influenced phonological awareness, evidenced by a β of 0.28 and a p-value of <0.01. This suggests that individuals with higher executive attention capabilities tend to have better phonological processing abilities. These results highlight the nuanced roles that cognitive processes play in influencing phonological awareness, underscoring the differential impact of mind-wandering and executive attention on language skills development. Conclusion: The study indicates the significant roles that both mind-wandering and executive attention play in phonological awareness. While mind-wandering may serve as a potential hindrance, executive attention appears to facilitate phonological processing skills.

AbstractThe generation of patient‐specific induced pluripotent stem (iPS) cells provides an invaluable resource for cell therapy, in vitro modeling of human disease, and drug screening. To date, most human iPS cells have been generated with integrating retro‐ and lenti‐viruses and are limited in their potential utility because residual transgene expression may alter their differentiation potential or induce malignant transformation. Alternatively, transgene‐free methods using adenovirus and protein transduction are limited by low efficiency. This unit describes a protocol for the generation of transgene‐free human induced pluripotent stem cells using retroviral transfection of a single vector, which includes the coding sequences of human OCT4, SOX2, KLF4, and cMYC linked with picornaviral 2A plasmids. Moreover, after reprogramming has been achieved, this cassette can be removed using mRNA transfection of Cre recombinase. The method described herein to excise reprogramming factors with ease and efficiency facilitates the experimental generation and use of transgene‐free human iPS cells. Curr. Protoc.

AbstractChelating resins have been considered to be suitable materials for the recovery of heavy metals in water treatments. A chelating resin based on modified poly(styrene‐alt‐maleic anhydride) with 2‐aminopyridine was synthesized. This modified resin was further reacted with 1,2‐diaminoethan or 1,3‐diaminopropane in the presence of ultrasonic irradiation for the preparation of a tridimensional chelating resin on the nanoscale for the recovery of heavy metals from aqueous solutions. The adsorption behavior of Fe2+, Cu2+, Zn2+, and Pb2+ ions were investigated by the synthesis of chelating resins at various pH's. The prepared resins showed a good tendency for removing the selected metal ions from aqueous solution, even at acidic pH. Also, the prepared resins were examined for the removal of metal ions from industrial wastewater and were shown to be very efficient at adsorption in the cases of Cu2+, Fe2+, and Pb2+. However; the adsorption of Zn2+ was lower than those of the others. The resin was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X‐ray diffraction analysis, and differential scanning calorimetry analysis. © 2012 Wiley Periodicals, Inc.

Published: May 2012

AbstractNumerous foodstuffs have been developed for lactose intolerant individuals. However, current methods to reduce lactose require excessive enzyme and are not viable for small producers. A novel solution proposed to overcome these problems is the immobilization of lactase to standard food‐contact packaging materials. The ability of these packages to convert lactose is dependent on the quantity and specific activity of the enzyme after immobilization. In this study, the material interface of polyethylene (PE) films was modified with polyethylene glycol (PEG) tethers of 1 kDa, 2 kDa, 5 kDa, and 10 kDa containing epoxy, acrylate, aldehyde, and succinimdyl ester end‐group functionality. The results showed that a 5 kDa tether enabled maximum absolute activity of 0.49 × 10−2 ALU/cm2 when compared to tethers of different sizes with identical functionalization. Compared to succinimdyl, epoxide, and acrylate functionalized PEG tethers, an aldehyde end‐group resulted in films with the highest absolute immobilized enzyme activity of 0.67 × 10−2 ALU/cm2. Regardless of tether size or chemistry, the activity retention of lactase was less than 15% compared to the soluble enzyme after immobilization to PEG‐functionalized PE films. © 2012 Wiley Periodicals, Inc.

Published: May 2012

AbstractThe development of surface microstructure with specific features in electrospun nanofibers has attracted more and more attention in recent years. In this article, a common biological polyester, poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) was electrospinning into nanofibers with “coral‐like” surface microstructure by a conventional‐electrospinning setup. The effect of the process parameters on the microstructure in electrospun nanofibers were investigated via a series of experiments. The formation mechanism of this feature structure and cytotoxicity assays of PHBV membrane were also discussed. The water contact angle of the electrospun PHBV membrane was higher than that of the PHBV cast film due to a very‐rough fiber surface including porous beads when PHBV was electrospun from the concentration of 4 wt %. Because of special hole shape and size distribution, the physical structure of surface of PHBV electrospun fibers offered it special properties, such as specific‐surface area, hydrophilic–hydrophobic properties, adhesion properties of cells and biological substances, etc. The demonstrated method of form coral structure would contribute to the areas such as filtration, sensor, tissue engineering scaffolds, and carriers of drugs or catalysis. © 2012 Wiley Periodicals, Inc.

Preparation and electrochemical performances of porous polypyrrole film by interfacial polymerization
Authors: Shen Mingxia , Han Yongqin , Lin Xiaochen , Ding Bing , Zhang Luojiang , Zhang Xiaogang 
Published: May 2012

AbstractIn this study, porous polypyrrole (PPy) film was synthesized by facile interfacial polymerization using ionic liquid as oxidant. The morphology of PPys changed from dense microspherical/nanospherical agglomerated structure to porous structure with the increasing concentration of the oxidant. The magnetic ionic liquid, 1‐butyl‐3‐methylimidazolium tetrachloroferrate (Bmim[FeCl4]), played a major role of oxidant when the concentration was lower than 0.075M. As the concentration increased to 0.075M, the π–π interactions between pyrrole cations and iminazole ring of Bmim[FeCl4], as evidenced by Fourier transform infrared spectrometer results, may affect the packing of PPy chains and subsequently cause the formation of porous structure of PPys. Electrochemical performances showed that PPy with porous structure displayed the highest specific capacitance of 170 F/g at a current density of 2 A/g in 1M H2SO4 solution and a good capacitive behavior, which has potential application as supercapacitor materials. © 2012 Wiley Periodicals, Inc.

Thermal properties of calcium carbonate powder reinforced vinyl ester composites: Pilot study
Authors: Ku Harry , Cardona Francisco , Jamal Eddine Mustapha 
Published: May 2012

AbstractThe viscoelastic properties of vinyl ester (VE) composites filled with calcium carbonate (CC) (CaCO3) powder have been evaluated using the dynamic mechanical analysis (DMA) technique. It was found that irrespective of the percentage by weight of CaCO3 powder, the VE composites postcured in an oven up to 60°C have higher glass transition temperatures (Tg) and storage modulus than their counterparts cured at ambient conditions. However, the loss moduli were lower for composites postcured in an oven than their ambient cured counterparts. It was also found that the crosslinking density of the composites slightly increased with particulate (CaCO3) loading and composites postcured in an oven have higher crosslinking density than their counterparts cured at ambient conditions. These results confirmed an increase in stiffness for composites with postcuring treatment. Micrographs by SEM were obtained and confirmed a close inter phase adhesion of the CC filler with the VE resin matrix in the composites. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

AbstractObjectiveTo systematically review evidence of the accuracy of the procalcitonin test for diagnosis of bacterial infection in patients with autoimmune disease.MethodsThe major databases Medline, EMBase, and the Cochrane Library were searched for studies published between January 1966 and October 2011 that evaluated procalcitonin, alone or in comparison with other laboratory markers such as C‐reactive protein (CRP), as a diagnostic marker for bacterial infection in patients with autoimmune disease and provided sufficient data to permit construction of 2 × 2 tables.ResultsNine studies were included in the final meta‐analysis. The area under the summary receiver operating characteristic curve values were 0.91 (95% confidence interval [95% CI] 0.88–0.93) for procalcitonin and 0.81 (95% CI 0.78–0.84) for CRP. In general, testing for procalcitonin was highly specific for identifying infectious complications, although it was not as sensitive as testing for CRP. Pooled sensitivity was 0.75 (95% CI 0.63–0.84) for procalcitonin tests and 0.77 (95% CI 0.67–0.85) for CRP tests. Pooled specificity was 0.90 (95% CI 0.85–0.93) for procalcitonin tests and 0.56 (95% CI 0.25–0.83) for CRP tests. The positive likelihood ratio for procalcitonin (7.28 [95% CI 5.10–10.38]) was sufficiently high to qualify procalcitonin testing as a rule‐in diagnostic tool, while the negative likelihood ratio (0.28 [95% CI 0.18–0.40]) was not sufficiently low to qualify procalcitonin testing as a reliable rule‐out diagnostic tool.ConclusionProcalcitonin has higher diagnostic value than CRP for the detection of bacterial sepsis in patients with autoimmune disease, and the test for procalcitonin is more specific than sensitive. A procalcitonin test is not recommended to be used in isolation as a rule‐out tool.
