Diagnosis and Treatment of Hepatoblastoma: An Update
Authors: Zhu Chengzhan , Dong Bingzi , Chen Xin , Dong Qian 
Published: January 2020

Hepatoblastoma is a rare but the most common solid tumor in children. The incidence is gradually increasing. The international collaboration among four centers in the world has greatly improved the prognosis of hepatoblastoma. They formed the Children’s Hepatic Tumor International Collaboration (CHIC) to standardize the staging system (2017 PRETEXT system) and the risk factors for tumor stratification. Multimodal therapy has become the standard for the management of hepatoblastoma, including surgical resection, liver transplantation, chemotherapy, and so on. Surgery is the primary treatment of early stage hepatoblastoma. Three-dimensional reconstruction is helpful for preoperative evaluation of large tumors, assisting extended hepatectomy for patients in PRETEXT III or IV. Neoadjuvant therapy is useful for reducing the tumor volume and increasing the resectability. Primary liver transplantation is recommended for advanced hepatoblastoma. The lungs are the most common metastatic organ, the treatment of which is critical for the patient’s long-term survival. We reviewed the recent progress in the diagnosis and treatment of hepatoblastoma.

Becoming Method(ologist): A feminist posthuman autoethnography of the becoming of a posthuman methodology
Authors: Warfield Katie 
Published: January 2020

This paper contributes to the intersections of post qualitative methods, digital methods, and internet studies, by describing the becoming of a digital posthuman visual method. I use posthuman autoethnography to argue that in the production of this method, the “auto” or my academic selfhood is decentered and entangled amidst an assemblage of material, discursive, and affective forces such as neoliberalism, Trump era terror, and dataism. I introduce a multitude of data points typically not made to matter but through which these material, discursive and affective forces importantly flowed in this production of this method: emails, personal correspondences, restaurant conversations, self-reflection, conferences talks and responses to conference talks. I focus specifically on the moments where the values and principles of feminist posthumanism were jarred and destabilized or where I was made to choose between foregoing my values or redesign my method and myself as methodologist. I argue academics have a response-ability to show both the forces at play behind the becoming of qualitative methods and knowledge in academia.

Introduction: Menopause simply refers to the time when a woman stops having monthly period. There have been numerous systematic studies into the age at onset of menopause and the factors affecting it, in different parts of the world. However, the establishment of this age and factors affecting it in Rivers state has been scanty.
Aim: This research was therefore undertaken to ascertain the age at onset of menopause in women of Rivers state, residing in Port Harcourt and the effect of parity, age at last child birth and form of birth control on it.
Methodology: This study used data from over 380 postmenopausal women from populations in Port Harcourt, Rivers state. Different ages specified by the respondents through structural questionnaires were used. The data was collected and analyzed using the ANOVA method. It was used to obtain a percentage frequency which was presented in a table.
Results: The result shows the mean menopausal age among Rivers state women to be 49.1 years. It was also found that menopausal age was affected by subjects’ parity, age at last child birth and form of birth control.
Conclusion: The mean menopausal age of women of Rivers State, living in Port Harcourt has been found to be 49.1 years. This age has also been found to be positively affected by a woman’s parity, age at last child birth and form of birth control.

Published: January 2020

In basic and applied biotechnology, design of affinity ligands has become essential for high‐capacity applications such as affinity‐based downstream processes for therapeutic molecules. Here, we established a proof‐of‐concept for the use of multimeric fusion single‐chain variable fragment (scFvs) as high‐capacity ligands in affinity adsorbents. Mono‐ and di/tri‐scFvs separated by Pro‐rich negatively charged linkers were designed, produced, and immobilized to 6% cross‐linked agarose beads. Frontal binding experiments with a target protein of 50 kDa resulted in up to 20 mg·mL−1 and 82% in dynamic binding capacity and utilization yield, respectively, at 100% breakthrough. The utilization of the binding sites was impacted by the ligand format and ligand density, rather than limitation in pore size of adsorbent as previously suggested. Overall, we demonstrated that multimeric fusion scFvs can successfully be developed and used as high‐capacity ligands in affinity adsorbents, enabling lean process design and alignment with process specifications.

AbstractOxygen evolution reaction (OER) catalysts that function efficiently in pH‐neutral electrolyte are of interest for biohybrid fuel and chemical production. The low concentration of reactant in neutral electrolyte mandates that OER catalysts provide both the water adsorption and dissociation steps. Here it is shown, using density functional theory simulations, that the addition of hydrated metal cations into a Ni–Fe framework contributes water adsorption functionality proximate to the active sites. Hydration‐effect‐promoting (HEP) metal cations such as Mg2+ and hydration‐effect‐limiting Ba2+ into Ni–Fe frameworks using a room‐temperature sol–gel process are incorporated. The Ni–Fe–Mg catalysts exhibit an overpotential of 310 mV at 10 mA cm−2 in pH‐neutral electrolytes and thus outperform iridium oxide (IrO2) electrocatalyst by a margin of 40 mV. The catalysts are stable over 900 h of continuous operation. Experimental studies and computational simulations reveal that HEP catalysts favor the molecular adsorption of water and its dissociation in pH‐neutral electrolyte, indicating a strategy to enhance OER catalytic activity.

Published: January 2020

AbstractConstructing microsupercapacitors (MSCs) with an outstanding stretchability is urgent for wearable electronics, and an intrinsic biodegradability is also meaningful. Herein, laser‐induced graphene/NiO/Co3O4 (NiO/Co3O4/LIG) is in situ synthesized on a polyimide (PI) film during laser processing, then the electrodes are transferred to a biodegradable waterborne polyurethane (WPU) substrate to fabricate stretchable MSCs. Experimentally, the as‐prepared stretchable MSCs exhibit an excellent areal capacitance of 2.4 mF cm−2, high capacitance retention of 77.1% at 50% strain, and capacitance degradation of less than 19.8% after 1000 stretching cycles. These desirable properties are mainly attributed to the gradient structure of NiO/Co3O4/LIG, the synergistic effect of hybrid NiO/Co3O4 nanoparticles, and the intensive interface adhesion between the electrodes and WPU. Interestingly, the robust function of stretchable MSCs is further presented by using them to power a microsensor and assembling them with triboelectric nanogenerators to generate power from mechanical contact with skin, which makes the stretchable MSCs promising as a sustainable driving source for wearable electronics.
Microcavity‐Enhanced Blue Organic Light‐Emitting Diode for High‐Quality Monochromatic Light Source with Nonquarterwave Structural Design

Published: January 2020

AbstractDespite their rapid development, organic light‐emitting diodes (OLEDs) are limited to display and lighting applications, and exploiting the application and development of OLEDs has become one of the critical issues. In this study, a new type of distributed Bragg reflector (DBR) with low absorption spacer as a bottom mirror is developed through nonquarterwave structural design. Different factors affecting the electroluminescence (EL) properties of microcavity OLEDs (MOLEDs) are investigated by using the optical microcavities with different structures to regulate the EL properties of 4,4′‐bis[(N‐carbazole)styryl] biphenyl (BSB‐Cz). The optimized MOLEDs with quarterwave DBRs exhibited a maximum external quantum efficiency of 8.86 ± 0.06%, demonstrating an enhancement of 79% compared to a reference device. Under the premise of almost not changing the electrical injection of the functional layer materials in the cavity, the spectral full‐width at half maximum of MOLEDs with a nonquarterwave structural design is as narrow as 2 ± 0.05 nm. These improvements are not only suitable for small organic molecules or polymeric materials, but also for novel nanoluminescent materials, such as quantum dots, perovskites, etc. Overall, the current study suggests the general applicability of this novel concept to obtain high‐quality monochromatic light, irrespective of the type of materials used.

AbstractSuper broadband near‐infrared (NIR) phosphor converted light‐emitting diodes (pc‐LEDs) are future light sources in NIR spectroscopy applications such as food testing. At present, a few blue LED excitable super broadband NIR phosphors (bandwidth > 300 nm) have been developed producing the NIR output powers below 26 mW at 100 mA input current after LED packaging. Here, an efficient super broadband NIR phosphor achieved by doping Yb3+ is reported in the NIR Ca2LuZr2Al3O12:Cr3+ (CLZA:Cr3+) garnet phosphor developed previously. Benefited from the superposition of Cr3+ emission and highly efficient Yb3+ emission excited by energy transfer from Cr3+, the codoped CLZA:Cr3+,Yb3+ phosphor shows a bandwidth of 320 nm and an internal quantum efficiency of 77.2% both higher than that (150 nm and 69.1%) of singly doped CLZA:Cr3+ phosphor. The codoped phosphor converts LED produced 41.8 mW NIR output at 100 mA input current. The pc‐LED as a light source is also well applied to the NIR transmission spectra measurement of water. The results indicate the great potential of CLZA:Cr3+,Yb3+ phosphor in super broadband NIR pc‐LED applications.

AbstractSynthesis of a wide variety of 3‐amino‐1H‐inden‐1‐ones from N‐tert‐butyl‐2‐(1‐alkynyl)benzaldimines via intramolecular aminocarbonylation of alkynes using Cs2CO3 as catalyst and air as oxidant has been developed. This highly atom‐efficient, transition‐metal‐free reaction proceeds under thermal conditions. We propose that the reaction proceeds through an unprecedented 5‐exo‐dig cyclization of N‐tert‐butyl‐2‐(1‐alkynyl)benzaldimines and thermal rearrangement of 3‐methylene‐2λ2‐isoindolin‐1‐ols.magnified image

Published: January 2020

AbstractAdoption of soil conservation practices has been promoted to improve environmental and economic benefits across the United States. These practices are especially necessary for soil health improvement in the Southern High Plains where soils are prone to erosion and agricultural irrigation relies heavily on groundwater. Winter cover crops and no‐till cropping are two conservation practices for reducing soil erosion, but producers might face additional risks associated with adopting these practices. The objective of this study was to examine the profitability and risks associated with alternative tillage and cover crops (no cover crop, winter wheat [Triticum asestivum L.], and grass–legume mixture) for irrigated cotton (Gossypium hirsutum L.). Using data from a 6‐yr field experiment, net return distributions of each production system were evaluated and ranked across various risk aversion levels. The results showed that the average net returns were $1040 and $1049 ha−1 for conventionally tilled and no‐till cotton without a cover crop, while the net returns were $1121 and $1075 ha−1 for no‐till cotton with wheat and mixed cover crops, respectively. Producers adopting cover crops had a greater probability of getting a middle interval of net returns between $760 and $1370 ha−1. The results of risk analysis show that risk‐neutral and slightly risk‐averse producers prefer no‐till cotton production with wheat cover, while no‐till with mixed and wheat cover are the first and second most preferred systems for very and extremely risk‐averse producers. Sensitivity analysis confirms consistent profit effects of cover crops and no‐till adoption at multiple cotton price levels.
The permeability of replicated microcellular structures in the Darcy regime
Authors: Otaru Abdulrazak J. 
Published: January 2020

AbstractThis study provides an extension to previously published articles on measurements and computational fluid dynamic (CFD) modeling and simulations of airflow across “bottleneck‐type” structures in the Forchheimer regime to purely inertial‐neglected (Darcy regime) incompressible flowing fluid via tomography datasets. A linear‐dependent relationship between the CFD computed unit pressure drop developed across the samples and the superficial fluid inlet velocity was observed for all the samples for creeping fluid flow (0–7 × 10−03m·s−1). The permeability of the structures was observed to be dependent on the structural parameters of the porous medium and most importantly, its pore diameter openings. Linear graphical relations between permeability and pore‐structure related properties of these materials were observed and these could assist in minimizing the number of design iterations needed for the processing of self‐supporting porous metals.
