FEATURES OF ORGANOPHOSPHATES IMMOBILIZATION VIA STREPTAVIDIN-BIOTIN SYSTEM FOR EXPERIMENTS ON SELECTION OF APTAMERS
Authors: Belinskaya D. A. , Chelusnova Yu. V. , Abzianidze V. V. , Goncharov N. V.
Published: August 2020

Poisoning with organophosphorus compounds occupy one of the leading places in exotoxicosis. At the first stage, the detoxification of organophosphates can be provided with the help of DNA or RNA aptamers that bind the poison in the bloodstream. Currently, the main method of searching for aptamers is the experimental method of systematic evolution of ligands by exponential enrichment (SELEX). In the process of aptamer selection, the target molecule must be immobilized via the streptavidin-biotin complex. Since the poison molecule is small in size, to increase its availability for binding to aptamer, it is necessary to use a spacer between organophosphorus compounds and biotin. The aim of this work was to optimize the selection of aptamers for organophosphorus compounds by increasing the availability of a poison molecule immobilized via the streptavidin-biotin complex on the example of paraoxon. For this purpose, three spacers between organophosphorus compounds and biotin were tested using molecular modeling methods: three links of polyethylene glycol (3-PEG), four links of polyethylene glycol (4-PEG) and aminohexyl. The conformation of the biotinylated paraoxon complex with streptavidin and the interaction of paraoxon with the binding fragment of the aptamer were modeled using molecular docking and molecular dynamics methods. The ability of biotinylated paraoxon to bind to the aptamer has been evaluated by analyzing the surface area of the paraoxon available to the solvent, as well as by calculating the free binding energies. It has been shown that only in the case of aminohexyl immobilized paraoxon can contact the aptamer. At the final stage, the synthesis of paraoxon bound to biotin via aminohexyl was carried out.

Data on the biological activity of kappa-opioid receptor agonists - derivatives of three groups of compounds: 1,2-cyclohexylamine, 1,2,3,4-piperidine, 1,2,4-piperazine are presented. On the examples of 1,2-cyclohexylamine and 1,2,4-piperazine derivatives, it has been shown that a decrease in the length of the carbon chain in the phenylalkyl substituent at the nitrogen atom is accompanied by a decrease in the analgesic activity and toxicity of compounds. The replacement of chlorine atoms in the 3 and 4 positions of the phenyl ring with fluorine atoms, which are more electronegative, leads to an increase in the analgesic effect and a decrease in the toxicity of the compounds.

Cosmological simulations, as well as mounting evidence from observations, have shown that supermassive black holes play a fundamental role in regulating the formation of stars throughout cosmic time. This has been clearly demonstrated in the case of galaxy clusters in which powerful feedback from the central black hole is preventing the hot intracluster gas from cooling catastrophically, thus reducing the expected star formation rates by orders of magnitude. These conclusions, however, have been almost entirely based on nearby clusters. Based on new Chandra X-ray observations, we present the first observational evidence for massive, runaway cooling occurring in the absence of supermassive black hole feedback in the high-redshift galaxy cluster SpARCS104922.6 + 564032.5 (z = 1.709). The hot intracluster gas appears to be fueling a massive burst of star formation (≈900 M
⊙ yr−1) that is offset by dozens of kpc from the central galaxy. The burst is co-spatial with the coolest intracluster gas but not associated with any galaxy in the cluster. In less than 100 million years, such runaway cooling can form the same amount of stars as in the Milky Way. Therefore, intracluster stars are not only produced by tidal stripping and the disruption of cluster galaxies, but can also be produced by runaway cooling of hot intracluster gas at early times. Overall, these observations show the dramatic impact when supermassive black hole feedback fails to operate in clusters. They indicate that in the highest overdensities, such as clusters and protoclusters, runaway cooling may be a new and important mechanism for fueling massive bursts of star formation in the early universe.
Induced Metal-free Star Formation around a Massive Black Hole Seed
Authors: Aykutalp Aycin , Barrow Kirk S. S. , Wise John H. , Johnson Jarrett L.
Published: August 2020

The direct formation of a massive black hole is a potential seeding mechanism of the earliest observed supermassive black holes. We investigate how the existence of a massive black hole seed impacts the ionization and thermal state of its pre-galactic host halo and subsequent star formation. We show that its X-ray radiation ionizes and heats the medium, enhancing H2 formation in shielded regions, within the nuclear region in the span of a million years. The enhanced molecular cooling triggers the formation of a ∼104
M
⊙ metal-free stellar cluster at a star formation efficiency of ∼0.1% in a single event. Star formation occurs near the edges of the H ii region that is partially ionized by X-rays; thus, the initial size depends on the black hole properties and surrounding environment. The simulated metal-free galaxy has an initial half-light radius of ∼10 pc but expands to ∼50 pc after 10 million years because of the outward velocities of their birth clouds. Supernova feedback then quenches any further star formation for tens of millions of years, allowing the massive black hole to dominate the spectrum once the massive metal-free stars die.
Hepatitis B Core-Related Antigen Levels Predict Pegylated Interferon-α Therapy Response in HBeAg-Positive Chronic Hepatitis B
Authors: Beudeker Boris JB , Groothuismink Zwier MA , de Man Robert A , Janssen Harry LA , van der Eijk Annemiek A , Boonstra Andre , Sonneveld Milan J
Published: August 2020

Background

Serum hepatitis B core-related antigen (HBcrAg) levels refect intrahepatic HBV replication activity. We aimed to study whether HBcrAg levels predict response to pegylated interferon (PEG-IFN) treatment in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients.

Methods

We studied HBcrAg levels in 222 HBeAg-positive patients treated with PEG-IFN with or without lamivudine for 52 weeks in a global randomized trial and compared kinetics across treatment arms and types of response. Optimal HBcrAg cutoffs for stopping therapy were compared to and combined with the currently recommended hepatitis B surface antigen (HBsAg)-based stopping-rules.

Results

Baseline HBcrAg levels could not discriminate between responders and non-responders ( P=0.91). HBcrAg levels of patients responding to PEG-IFN therapy showed a more pronounced on-treatment decline (mean declines 3.4 versus 1.0 log U/ml; P<0.0001), which was sustained until the end of follow-up (mean declines week 78, 3.8 versus 1.0 log U/ml; P<0.0001). In the PEG-IFN mono-therapy group, HBcrAg levels of >8.35 log U/ml at week 24 identified 19 patients (19%) of whom 1 (negative predicitve value [NPV]=95%) achieved a response. The performance of this HBcrAg-based stopping rule alone was not superior to the one based on HBsAg >20,000 IU/ml. Among patients with an HBsAg <20,000 ( n=56), 9 (16%) had an HBcrAg >8.35, of whom 8 achieved no response (NPV 89%).

Conclusions

HBeAg-positive CHB patients with a response to PEG-IFN therapy achieve a more pronounced HBcrAg decline. HBcrAg levels at week 24 of therapy could be used to identify non-responders in combination with the established HBsAg-based stopping-rules.
Gastroparesis
Authors: Hsing Li-Chang , Jung Kee Wook
Published: August 2020

Gastroparesis is a condition characterized by delayed gastric emptying without evidence of mechanical obstruction in the stomach. Its symptoms include nausea, vomiting, early satiety, abdominal bloating, and abdominal pain. Most cases of gastroparesis are either idiopathic, due to diabetes mellitus, or post-surgical complications. The diagnosis of gastroparesis requires upper endoscopy, contrast radiography, or validated gastric scintigraphy. Gastroparesis is managed with nutritional support and treatment of any underlying disorders, such as diabetes. Pharmacological treatments have been tried, including prokinetics and novel medications. Interventions focused on the pylorus have shown promising results.
Trimalleolar Fractures: Late Results After Fixation of the Posterior Fragment
Authors: Heim Urs F A
Published: August 2020

ABSTRACT: From 1969 to August 1981 60 trimalleolar fractures were operated on with fixation of the posterior fragment. A late follow up (average 8 years) including radiographs was possible in 45 patients. In 36 patients, there are no complaints and full function has been obtained. Films of the articulation are normal in 17 cases and show isolated osteophytes in 19. Five patients show some benign arthrosis but only occasional pain and slightly reduced function; four patients show severe arthrosis caused by clearly visible operative technical faults. Depressed areas in the articular surface were present in ten patients. Their prognosis is doubtful. Thus, a correctly reduced and fixed posterolateral fragment helps avoid or reduce postoperative arthrosis in trimalleolar injuries.
Use of a Suture Anchor Technique to Replace the Tethering Effect of the Ligamentum Teres in the Treatment of Complex Hip Dysplasia
Authors: Magister Steven J. , Liu Raymond W.
Published: August 2020

After open hip reduction in hip dysplasia, some hips can have persistent instability, even after pelvic and femoral osteotomies as well as capsulorrhaphy. While the diseased ligamentum teres in a dislocated hip is thought to contribute to inadequate reduction, the native ligament is thought to provide some level of stability. As such, the purpose of this study was to investigate the utility of a suture augment that replaces the function of the ligamentum teres to provide added stability. [

Authors: Parnes Nata , Tousant Cheryl , Perrine Jeff , DeFranco Michael J.
Published: August 2020

The COVID-19 pandemic has had a strong impact on the care of orthopedic patients. This impact has been particularly difficult in New York State, which experienced the largest number of COVID-19 cases and led to a state- mandated pause on all elective surgeries. As a result, physical and occupational therapists became the principal providers of care and had to adjust their workflow to ensure quality care. Understanding the perspectives and needs of therapists relative to the circumstances created by COVID-19 is critical to safe and effective care. The goal of this study was to define the perspectives of therapists in New York State regarding the impact of COVID-19 on their work. An email-based 20-question survey was distributed to 250 therapists from all 10 regions of New York State who treated outpatient orthopedic patients during the peak of the pandemic in early April 2020. The survey collected demographic and practice information as well as responses regarding several clinical practice issues. The results provide insight into the concerns of therapists regarding the delivery of care, and responses clarify indications for therapy and for the use of telemedicine to achieve goals during the pandemic. The COVID-19 pandemic is profoundly impacting the work of therapists worldwide. Therapists responded to this survey expressing concerns about the safe delivery of care, access to personal protective equipment, use of telemedicine, and their role within health care during the pandemic. The results of this study can be used to establish guidelines for safe, effective, and efficient therapy during the pandemic. [

One SYK single electron transistor
Authors: Khveshchenko Dmitri V.
Published: August 2020

We study the behaviour of a single electron transistor (SET) represented by a dissipative tunnel junction between a pair of quantum dots described by two (possibly, different) Sachdev–Ye–Kitaev (SYK) models. A combined influence of the soft collective charge and energy modes on charge transport is discussed, alongside the competing effects of the Coulomb blockade and emergent Kondo resonances which might all conspire to result in a non-monotonic behaviour of the system’s conductance.
Measuring E-Learning System Adoption in Universities in Tanzania
Authors: Lashayo Deogratius Mathew
Published: August 2020

The success of e-learning systems in Tanzania relies on various factors that influence its measurement. Examples of the key factors include trust, environmental factors, and the university readiness. However, influence of these factors towards e-learning systems is not clear. Understanding their impacts and significance helps decision makers and stakeholders in making informed decisions on how to handle them. This study modifies the information systems (IS) success model whereby it adopts 12 factors that had been suggested by this author in his previous study conducted in Open University of Tanzania (OUT) in 2017. A sample of 1,005 students from eight universities in Tanzania was collected. A structural equation modelling was used in data analysis. The results shows trust (T) has positive and significant impact on e-learning actual use (EAU) while environmental factors (EF) had positive and significant impacts on e-learning actual use and perceived benefits, and at the same time, university readiness had a positive and significant impact on perceived benefits (PB).
Information Technology Adoption Dynamics for SMEs in the Manufacturing Sector of Namibia
Authors: Baporikar Neeta , Shikokola Sigried
Published: August 2020

Small to medium-sized enterprises (SMEs) account for employment, technological advancements, and competitive advantages in developed and developing countries. SMEs face intense competition from large corporations; therefore, to be competitive and sustainable, there is a need to adopt information technology (IT). However, SMEs have fewer financial resources, lower technical expertise, and lack of management skills. They are likely to be less prepared and may even be unable to deal with information technology adoption dynamics. Therefore, though there is a significant contribution by IT to business, many studies show unsuccessful IT implementations and slow adoption rates by SMEs. This paper uses a qualitative research approach to find out to what extent SMEs in the manufacturing understand IT, whether they have adopted IT and identify IT adoption dynamics in Namibia. Findings reveal that internal factors like top management, resources, end-users and external factors like competitive pressures, IT consultants, and government influence the SMEs in IT adoption.

Authors: Taengwa Chaiyanan , Kaewvilai Attaphon
Published: August 2020

This work presented the hardfacing process of high-strength structural steel based on JIS G3106 standard grade SM490YA by semi-automatic flux-cored arc welding with a dual shielding process of flux-cored self-shielded and protective gas-shielded (FCAW-G). In the welding process, the surface of SM490YA specimen was hardfacing welded by metal cored wire based on chromium carbide which was in standard of 8555: E10-MF-65-G. The hardfacing welds from FCAW-G and traditional self-shielding FCAW (FCAW-S) with and without preheat were inspected by visual and penetrant tests for evaluating the welding quality. The macrostructure of the deposited layer was investigated by optical microscope and image analysis for analyzing the weld penetration and weld dilution. In addition, the hardness of the hardfacing welded specimens was tested for the evaluation of the surface durability of the welded SM490YA.

Published: August 2020

Nowadays, the industry has been growing interest in lightweight material for automotive and cookware manufacturing. The formability of sheet material is an important issue in these industries. The wrinkling behavior is one of the most failure in sheet metal forming and is often occurred in deep drawing process in cookware manufacturing. In this work, the developed wrinkling limit curves (WLCs) using experimental and numerical simulation of a modified Yoshida buckling test were precisely used to predict the wrinkling behavior of rectangular cup deep drawing for aluminum alloy sheets grade AA5054-O and AA5052-H32. The Industrial parts, the rectangular cup deep drawing was firstly performed for both investigated aluminum sheets for obtaining the wrinkling initiation on the side wall area of deep drawing parts. Subsequently, the experimental formed parts were carefully measured the draw-in of deformed blank sheets and drawing depth to validate the finite element (FE) model. Then, the FE simulation of the corresponding drawing tests were calculated, by which were implemented with the Hill’48 yield criterion and Swift hardening law to descript anisotropic plastic deformation. As a result, the local principle Major and Minor principle strains of observed wrinkle areas were gathered in the side wall area of the rectangular cup deep drawing test. Finally, the developed WLCs of aluminum alloy sheets were applied to predict the wrinkling formation of the formed deep drawing parts. Comparatively, the influence of different aluminum alloy grades on the WLCs and wrinkling behavior were explicitly investigated.

Published: August 2020

Ion removal is a long problem on natural freshwater resources. In order to modify the adsorption performance to remove ions from standard iron solution, natural zeolite and natural perlite were treated with deionized water (DI water) as D-zeolite and D-perlite. And, 1M sulphuric acid (H2SO4) was used to treat the adsorbent as H-zeolite and H-perlite. The capability of ion removal was preliminarily investigated from the reduction of iron in solution by X-ray fluorescence spectrometer. The result showed that treatment of adsorbents with DI water was more capability than 1M H2SO4 solution.
Physical and Mechanical Properties of Poly(Butylene Succinate) and Poly(Lactic Acid) under Landfill Conditions
Authors: Seeponkai Narumon , Poolsawat Krisana
Published: August 2020

In this study, the disintegration of poly(butylene succinate)(PBS) and poly(lactic acid) (PLA) under landfill conditions was investigated. Both polymers were melted, injected into a dumbbell-shape, and buried under the soil for 20 weeks. The morphology of the polymer from the scanning electron microscope (SEM) revealed that, after 6 weeks of the burial, the PBS polymer produced many micro-voids in the bulk of polymer. The amount of the voids increased with time. While the morphology of PLA showed a few voids and some cracks during the degradation process. Moreover, the mechanical properties of the PLA were decreased after 2 weeks following with PBS after 4 weeks of the burial times. The weight loss and the water uptake of PBS and PLA were slightly increased. From the result, it was found that the degradation of PBS and PLA proceeds via random chain scission of the ester bond through bulk erosion mechanism. The degradation of PLA degraded faster than the PBS due to the low crystallinity in the polymer chain. This result can be applied to the design waste management of biodegradable polymer products.
Effect of Double-Step Solution Treatment on Rejuvenation Heat Treated Microstructure of IN-738 Superalloy
Authors: Paa-Rai Chuleeporn
Published: August 2020

This work investigates the effect of rejuvenation heat treatment, with double-step solution treatment at the temperature from 1150 °C to 1200 °C, on the recovered microstructure of IN-738 cast superalloy. The superalloy has been long-term exposed as a turbine blade in a gas turbine prior to this study. After double solution treatment and aging at 845 °C for 12 h and 24 h, the recovered microstructures were examined by using a scanning electron microscope. Coarse γ΄ particles, that have presented in damaged microstructures, could not be observed in the samples after the rejuvenation heat treatment. In addition, the image analysis illustrates that the reprecipitated γ΄ particles in the samples with double-step solution treatments increase significantly in sizes during aging than that in the samples with the single-step solution treatment. Furthermore, the measurement of the samples hardness presents that the as-receive sample hardness is improved after rejuvenation heat treatment studied in this work.
Development of Stress- and Strain-Based Fracture Forming Limit Curves of Sheet Aluminium-Alloy AA2024-T3 through Various Approaches
Authors: Jantarasricha Tanakorn , Panich Sansot , Chongbunwatana Komkamol
Published: August 2020

In this work, four fracture criteria—namely, Fracture Forming Limit Curve (FFLC), Fracture Forming Limit Stress Curve (FFLSC), Fracture Locus (FL) and Fracture Locus Embedded with Bao-Wierzbicki Ductile Damage Criterion (BW-FL)—are comparatively deployed to forecast breakage of deformed AA2024-T3 sheet aluminium-alloy. An FFLC can be experimentally formed by conducting a set of Nakajima stretch-forming based tests. To obtain an FFLSC, such an FFLC drawn in the strain space has to be entirely mapped onto the stress space. This can computationally be accomplished with the help of those well-known plasticity-relevant models like the Hill’48 anisotropic yield criterion and the Swift hardening law. Likewise, both BW-FL and FL in terms of stress triaxialities and critical plastic strains can mathematically be derived from the FFLC incorporated with the Hill’48 anisotropic yield criterion. Hole expansion and tree-point bending tests are carefully carried out both experimentally and simulatively to verify those four generated fracture limits. The more innovative FFLSC and FL demonstrate more accurate prediction on rupture of AA2024-T3 sheet aluminium-alloy than the conventional FFLC. The BW-FL however performs the worst.

This paper explores the possibility of using different 3d printing methods and materials in the production of polymer molds for injection molding applications. A mold producing a cube was designed using a commercial software. Following the standard 3d printing process, injection molds which could produce a cube were printed using different 3d printing materials and 3d printing technologies. The 3d printing technologies used were Stereolithography (SLA), Polyjet and Fused Filament Fabrication (FFF). A bench-top injection molding machine was used to inject polylactic acid (PLA) in these molds. The quality of the injected parts in terms of dimensional accuracy has been investigated. In some cases, the damage mechanism of the polymer molds has also been observed.
