Authors: Bhargava Nishant , Singh Vivek , Bhat Tameem , Sahu Chandradev
Published: May 2019

Arachnoiditis ossificans (AO) is a rare disorder characterized by calcification of arachnoid membranes first described by Kaufman and Dunsmore in 1971. It is a very rare cause of spinal canal stenosis leading to neurological compromise presenting with progressive lower extremity myelopathy. It has been described to be a sequela of various conditions previous intradural surgery, myelograms, vascular malformations and adhesive arachnoiditis. Associated conditions may include syringomyelia. The imaging findings on MRI may be confusion. Preferred diagnostic method is non contrast computed tomography (CT). Surgical intervention is still controversial and can include decompression. The authors report the case of 48 years female presenting with gradually progressing paraparesis. Magnetic resonance imaging of the spine revealed a spinal cord syrinx but with an extramedullary intradural hypo-intensity. A computed tomography scan clearly demonstrated the abnormality and its extent. We present a unique case of syringomyelia resulting from spinal arachnoiditis ossificans and review the relevant literature. This case reports a unique presentation of arachnoiditis ossificans with syringomyelia in which etiology is not clear. We also highlight the difficulty is diagnosis on MRI and need of non-contrast CT.

Coexistence of acute epiploic appendagitis with acute pyelonephritis is a rare occurrence. Present study report here a case of a 36-year-old male with a past history of appendectomy presenting with complaints of pain abdomen, nausea, increased frequency of micturition and dysuria. On examination, there was tenderness and guarding in the left iliac fossa. CECT abdomen revealed resolving acute epiploic appendagitis with acute pyelonephritis. He was managed conservatively with antibiotics and anti-inflammatory agents to which he responded. Thus, epiploic appendagitis is a benign self-limiting condition which when diagnosed early prevents unnecessary surgical interventions.

Authors: Hazarika Basanta , Sharma Suresh , Kumar Ritesh , Sarma Jogesh
Published: May 2019

Background: Tuberculosis is a common cause of pleural effusion especially in countries like India. ADA (adenosine deaminase) is predominantly an enzyme, that catalyses the conversion of adenosine to ionosine. Usually patients with tuberculous pleural effusion have ADA level >40 U/L.Methods: This is a prospective, observational study conducted in Department of Pulmonary Medicine, Gauhati Medical College and Hospital, Guwahati from September 2016 to September 2017. 45 patients with pleural fluid ADA levels >40 U/L were selected with diagnosis of tubercular pleural effusion. Pleural fluid was analysed for cytological, biochemical and microbiological parameters along with ADA and malignant cell cytology. Anti-tubercular treatment (ATT) was started and pleural fluid ADA level were repeated after 15 days of ATT.Results: Pleural fluid ADA levels before the start of ATT intake and after 15 days of ATT intake were statistically analysed. Among 45 patients, 38 were male and 7 females.  Mean age of the patients was 45.42±16.43 years. Mean pleural fluid ADA level before starting ATT was 64.49±31.78 U/L. After 15 days of ATT intake mean pleural fluid ADA level was 36.11±10.42 U/L, p value was statistically significant (p<0.05).Conclusions: Pleural fluid ADA significantly decreased after 15days of initiation of anti-tubercular treatment. Pleural fluid ADA can be a useful tool as a follow up biomarker in cases of tubercular pleural effusion.

Economic Theory to Visualize the Value of Design: a Case Study on The User’s Perception of Value
Authors: Morejon Alava Maria Cristina
Published: May 2019

Following John Heskett (2017), this paper posits that economic value cannot be defined without transcending and acknowledging the user as its source. His research presents economic theory linked to the value creation process applicable to study the value of design. This paper proposes that economic theory can be used to evaluate the impact of design when understanding and interpreting the subjective perception of value. A plan for a cross-sectional case study is explained to collect and analyze qualitative data in two stages with a means-end theory approach. This research aims to: (1) Understand the user’s perception of value, (2) Evaluate the impact of design by reflecting on economic theory and (3) Analyze the relationship between design and economics regarding economic value to contribute to the business of design. It may lead to the development of an evaluation model to guide organizations towards the creation or improvement of products, services or systems with a better understanding and a more measured perception of how users perceive value for decision-making.

Authors: Hemmati-Sarapardeh Abdolhossein , Hajirezaie Sassan , Soltanian Mohamad Reza , Mosavi Amir , Shamshirband Shahab
Published: May 2019

A Natural gas is increasingly being sought after as a vital source of energy, given that its production is very cheap and does not cause the same environmental harms that other resources, such as coal combustion, do. Understanding and characterizing the behavior of natural gas is essential in hydrocarbon reservoir engineering, natural gas transport, and process. Natural gas compressibility factor, as a critical parameter, defines the compression and expansion characteristics of natural gas under different conditions. In this study, a simple second-order polynomial model based on the group method of data handling (GMDH) is presented to determine the compressibility factor of different natural gases at different conditions, using corresponding state principles. The accuracy of the model evaluated through graphical and statistical analyses. The results show that the model is capable of predicting natural gas compressibility with an average absolute error of only 2.88%, a root means square of 0.03, and a regression coefficient of 0.92. The performance of the developed model compared to widely known, previously published equations of state (EOSs) and correlations, and the precision of the results demonstrates its superiority over all other correlations and EOSs.

Layout estimation is a challenge of segmenting a cluttered room image into floor, walls and ceiling. We applied Double refinement network proved to be efficient in the depth estimation to generate heat maps for room key points and edges. Our method is the first not using encoder-decoder architecture for the room layout estimation. ResNet50 was utilized as a backbone for the network instead of VGG16 commonly used for the task, allowing the network to be more compact and faster. We designed a special layout score function and layout ranking algorithm for key points and edges output. Our method achieved the lowest pixel and corner errors on the LSUN data set. The input image resolution is 224*224.
Influenza Management Prospects of Passive Immunotherapy
Authors: Kotey Erasmus , Lukosaityte Deimante , Quaye Osbourne , Ampofo William , Awandare Gordon , Iqbal Munir
Published: May 2019

Influenza is a disease that poses a significant health burden worldwide. Vaccination is the best way to prevent influenza virus infections. However, conventional vaccines are only effective for a short period of time due to the propensity of influenza viruses to undergo antigenic drift and antigenic shift. The efficacy of these vaccines is uncertain from year-to-year due to potential mismatching between the circulating viruses and vaccine strains, mutations arising due to egg adaptation, and potential contamination of the vaccine virus stock. Subsequently, the inability to store these vaccines long-term and vaccine shortages are challenges that need to be overcome. Conventional vaccines are also less effective for certain populations, including the young, old, and immunocompromised. This warrants for diverse efficacious vaccine developmental approaches, involving both active and passive immunization. As opposed to active immunization platforms (requiring the use of whole or portions of pathogens as vaccines), the rapidly developing passive immunization involves administration of either pathogen-specific or broadly acting antibodies against a kind or class of pathogens as a prophylactic treatment to corresponding acute infection. Several antibodies with broadly acting capacities have been discovered that may serve as means to suppress influenza viral infection and allow the process of natural immunity to engage opsonized pathogens whilst boosting immune system by antibody-dependent mechanisms that bridge the innate and adaptive arms. By that, passive immunotherapeutics approach assumes a robust tool that could aid control of influenza viruses. In this review, we comment on some improvements in influenza management and promising vaccine development platforms, with emphasis on the capacity of passive immunotherapeutics especially when coupled with the use of antivirals in the management of influenza infection.

Authors: Heidinger Michael , Xia Qihao , Simon Christoph , Denk Fabian , Eizaguirre Santiago , Kling Rainer , Heering Wolfgang
Published: May 2019

This paper presents a control algorithm for soft-switching series LC converters. The conventional voltage-to-voltage controller is split into a master and a slave controller. The master controller implements constant-current-constant-voltage (CCCV) control, required for demanding applications, i.e. lithium battery charging or laboratory power supplies. It defines the set-current for the open-loop current slave controller, which generates the PWM parameters. The power supply achieves fast large-signal responses, e.g. from 5 V to 24 V, where 95% of the target value is reached in less than 400 µs. The design is evaluated extensively in simulation and on a prototype. A consensus between simulation and measurement is achieved.
Development of a New Temperature Measurement System for the Observation of Adiabatic Shear Band
Authors: Pawelko Romain , Pina Vincent , Hervé Philippe
Published: May 2019

This paper presents the development of a new system designed to measure the local temperature field in adiabatic shear band. Transient temperature field are simultaneously recorded by an array of 32 InSb infrared (IR) detectors and a streak camera working in visible-near infrared (VIS-NIR). Observations in IR offer a low temperature detection limit (350°C) but they are highly sensitive to uncertainty in the emissivity. Observations in VIS-NIR allow for measurement only at high temperatures (750°C) but they are less affected by uncertainty on emissivity and present a higher temperature sensitivity. By performing simultaneous measurements, it is possible to obtain data on a large temperature range with an improved accuracy at high temperature. The different sources of errors caused by uncertainty in the emissivity, spatial and temporal resolution of the detectors has been analyzed and an estimation of the total measurement uncertainty of the system is given.

Published: May 2019

Microbe-plant interactions are linked with the core microbiota, and both the plant and the microbial partners depend on one other to thrive in nature. However, why and how the below-ground core microbiota become established aboveground is poorly understood. We tracked the movement of a probiotic Streptomyces endophyte throughout a managed strawberry ecosystem. Probiotics in the rhizosphere and anthosphere were genetically identical, yet these niches were segregated in space and time. The probiotic in the rhizosphere moved upward via the vascular bundle, relocated to aboveground plant parts, and protected against Botrytis cinerea. It also moved from flowers to roots, and among flowers via pollinators that were protected against pollinator pathogens. Our results reveal a solid evidence in tripartite interaction with Streptomyces exploiting plant and pollinator partners.
Optinalysis: A New Approach of Multivariate Analysis through A Looking-Glass
Authors: Abdullahi Kabir Bindawa
Published: May 2019

Optinalysis, as a method of symmetry detection, is a new advanced computational algorithm that intrametrically (within elements) or intermetrically (between elements) computes and compares two or more multivariate sequences in an unclustered or clustered manner as a mirror-like reflection of each other (optics-like manner), hence the name is driven. Optinalysis is based by the principles of reflection and moment about a symmetrical line which detects symmetry that reflects a similarity measurement. Optinalysis is suitable for quantitative and qualitative data types, with or without replications, provided it conform the algorithmic requirements there provided. Optinalysis can be organized for geometrical, geostatistical and statistical analysis in one-way, two-way, or three-way approach. A simulation comparisons shows that Optinalysis is a simple alternative approach of multivariate analysis of sociometric, demographic, socio-demographic, psychometric, ecological, experimental, genomic, nanoparticle and shape morphometric data. Optinalysis of these data matrix shows very similar results or conclusions with some multivariate analysis such as skewness measure, one-way ANOVA, paired t-test, one sample t-test, Tukey’s multiple comparisons, BLAST sequence algorithmic analysis (percentages of identity, similarity, gabs, and positives, and the Needleman-Wunsch score), and Riemannian distance.

Published: May 2019

The influence of lignin modification on drug release and pH-dependent releasing behaviour of oral solid dosage form was investigated using three different formulations. The first formulation contains microcrystalline cellulose (MCC101) as excipient and paracetamol as active pharmaceutical ingredient (API). The second formulation includes Alcell lignin and MCC 101 as excipient and paracetamol, and the third formulation consists of carboxylated Alcell lignin, MCC 101 and paracetamol. Direct compaction was carried out in order to prepare the tablets. Lignin can be readily chemically modified due to the existence of different functional groups in its structure. The focus of this investigation is on lignin carboxylation and its influence on paracetamol control release behaviour at varying pH. Results suggest that carboxylated lignin tablets had the highest drug release, which is linked to their faster disintegration and lower tablet hardness.

Authors: Zhou Wei , Bellis Emily S. , Stubblefield Jonathan , Causey Jason , Qualls Jake , Walker Karl , Huang Xiuzhen
Published: May 2019

Background

Minor QTLs mining has a very important role in genomic selection, pathway analysis and trait development in agricultural and biological research. Since most individual loci contribute little to complex trait variations, it remains a challenge for traditional statistical methods to identify minor QTLs with subtle phenotypic effects. In this study, we developed a new framework which combined the GWAS analysis and machine learning feature selection to explore new ways for minor QTLs mining.

Results

We studied the soybean branching trait with the 2137 accessions from soybean (Glycine max) diversity panel, which was sequenced by 50k SNP chips with 42,080 valid SNPs. First as a baseline study, we conducted the GWAS GAPIT analysis, and we found that only one SNP marker significantly associated with soybean branching was identified. We then combined the GWAS analysis and feature importance analysis with Random Forest score analysis and permutation analysis. Our analysis results showed that there were 36077 features (SNPs) identified by Random Forest score analysis, and 2098 features (SNPs) identified by permutation analysis. In total, there were 1770 features (SNPs) confirmed by both of the Random Forest score analysis and the permutation analysis. Based on our analysis, 328 branching development related genes were identified. A further analysis on GO (gene ontology) term enrichment were applied on these 328 genes. And the gene location and gene expression of these identified genes were provided.

Conclusions

The combined GWAS and feature selection with machine learning methods provide a new analysis framework, which shows significant identification power for minor QTLs mining. This research on minor QTLs mining helps to understand the biological activities that lies between genotype and phenotype in terms of causal networks of interacting genes. This research also provides an integrative approach for effective genomic selection in plant breeding and help broaden the way of molecular breeding in plants.

Published: May 2019

Background: To assess the time-efficiency of a designated operation room (OR) workflow in the introduction of Femtosecond laser-assisted cataract surgery (FLACS, LenSx, Alcon®). The study was carried out in a public hospital with high volume of procedures.
Methods: We performed this prospective, controlled, surgical intervention study in the Ophthalmology department of a tertiary referral Spanish public hospital. A total of 167 eyes were enrolled, including 62 eyes undergoing conventional phacoemulsification surgery. In phase I, patients were assigned either to FLACS-I (n=63) or conventional phacoemulsification surgery (n=62). One surgeon operated the Femto-second laser, another finished the procedure, whereas another performed a conventional phacoemulsification. In the second phase (FLACS-II), all the surgeries were FLACS (n=42). A surgeon performed the FLACS procedure and two different surgeons completed the surgeries in separated ORs. Surgical and roll-over times of all the patients were recorded.
Results: Preparation time was statistically significant lower in FLACS-I and FLACS-II (p<0.001) whereas the time of the cataract procedure per se was higher in FLACS-II compared to conventional phacoemulsification (p= 0.03). Phacoemulsification energy was higher in FLACS-II compared to FLACS-I (p = 0.01) whereas laser-related surgical time was lower (p = 0.001). Surgical complications and total surgical time showed no statistically significant differences between all three groups.
Conclusions: This study suggests a time-efficient and suitable workflow model for FLACS considering the specific requirements and restrictions of a saturated public hospital. Even so we have shown that FLACS procedure does not take longer than conventional phacoemulsification following a detailed planning for the OR workflow. Besides, our data reflect an improvement surgical times in FLACS with ongoing experience.

An increase in industrialization and various kind of human activities added a huge amount of toxic heavy metals in the soil. As a result, toxic heavy metals in the environment may be adversely affects human being and aquatic ecosystem. Thus, it is very essential to understand mechanism of bioremediation through eco-friendly agent i.e. bacteria. Accumulation of high metal concentrations in soil above threshold limit causes lethal to bacterial communities in the environment. Few bacteria develop resistance mechanism to tolerate these toxic heavy metals and contain various methods to respond the metal stress. The present review emphasizes to understand the mechanism of bacterial resistance against toxic metals. Moreover, mechanism of bioaugmentation, biosorption, and bioaccumulation methods also described clearly.

Рurpose. The determination of adaptive ability of Schisandra chinensis (Turcz.) Baill plants to drought under the conditions of introduction in the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine on the basis of study of morpho-anatomical and biochemical features of the leaves. Methods. The anatomical structure of S. chinensis leaves was studied by light microscopy using fresh and dried raw materials. The water retention capacity was determined by laboratory method according to the rate of water loss and the degree of damage to isolated leaves. The dynamics of the content of pigments in S. chinensis leaves was determined by the spectrophotometric method during the vegetation period. Results. Certain morpho-anatomical signs of S. chinensis leaves contributing to plant resistance to conditions with high air temperature and water deficiency were identified – the presence of a wax layer on the surface of the epidermis and cuticle, calcium oxalate crystals and secretory cells. According to the scale of the parameters of water regime of leaves, the studied plants are characterized by high level of adaptation to drought too. It was revealed that the pigment complex of leaves is sensitive to changes in the environmental factors. The content of pigments in the plant leaves varies with changes in hydrothermal conditions of growth. The dynamics of the content of chlorophylls and carotenoids is related to the physiological state of plants and to a certain degree characterizes their adaptive potential. Conclusions. The results of morpho-structural studies of S. chinensis leaves and their water-physical properties indicate a high level of adaptability of plants to environmental stressors such as insufficient water supply and high temperature. S. chinensis plants can be recommended for widespread introduction into garden cenosis for obtaining valuable fruit and medicinal raw materials.

Purpose. Investigate the drought tolerance of woody vines of Ampelopsis Michx and Parthenocissus Planch. genera introduced in the Right-Bank Forest-Steppe of Ukraine on the specificity of leaf surface anatomical and morphological structure, peculiarities of water regime of the leaves and characteristics of physicochemical processes inside their tissues during wilting. Methods. Field surveys, morphometric, physiological, statistical. Results. The drought resistance of woody vines of the Ampelopsis and Parthenocissus genera of the Vitaceae family collection at the M. M. Gryshko National Botanical Garden collection site “Climbing plants” was studied. According to visual observations, during periods with a low level of moisture supply, there was no damage to leaves, turgor did not decrease. The main differences in the structure of the abaxial epidermal surface of woody vine leaves of the Ampelopsis and Parthenocissus genera are in the form of epidermal cells and a number of stomata. The electrical conductivity of the leaves of all the studied plants decreased stably during wilting (on average, by 0.12–0.19 mcS in two hours of wilting). The leaf water loss as a result of wilting was 10.05–25.63%. In conditions of insufficient moisture supply water deficit of leaves was at the level of 6.16–8.87%. Conclusions. According to the value of average long-term assessment of actual drought tolerance, the studied plants have a high degree of drought tolerance. The stomatal apparatus of woody vines of the genus Ampelopsis is distinguished by a greater manifestation of signs of xeromorphism than members of the genus Parthenocissus. High adaptability of the studied plants to growing conditions was revealed. High level of water holding capacity of the leaves was determined. It was revealed that in the period with low moisture provision the water stress in the leaves was low. The studied representatives are distinguished by a high degree of drought resistance due to the presence of signs of xeromorphism in the anatomical and morphological structure of the leaf surface, as well as the peculiarities of water regime and physicochemical processes inside leaf tissues, which makes it possible to use them extensively in the conditions of introduction.

Purpose. Identification of soybean growth and development peculiarities as affected by the application of organic fertilizer, plant growth regulators and water retaining agent under the conditions of the Forest-Steppe of Ukraine. Methods. The study involved soybean varie­ties ‘Ustia’, ‘Kano’ and ‘Hieba’. A month before sowing soybean, water retaining agent (hydrogel Aquasorb) was introduced in the zone of the future row as 10-cm strips at a dose of 300 kg/ha. Organic fertilizer Parostok (grade 20) was applied twice: at the 3–5 leaf stage and at the 9–11 leaf stage. Growth regulators Vermystym-D and Agrostymulin were introduced at the budding stage. Results. It was found that the assimilation surface (m2/ha) of ‘Ustia’ crops in the treatments without hydrogel at the flowering stage was 38,200, while in the treatment with hydrogel it made up 43,600. In ‘Kano’, application of organic fertilizer ensured a leaf surface of 38,600 m2/ha in the treatment without hydrogel and 45,800 with hydrogel. Similar patterns were recorded in ‘Hieba’: 39,000 and 44,900, respectively. Organic fertilization of ‘Kano’ stands contributed to the formation of an assimilation surface of 38,600 in the treatment without hydrogel and 45,800 with hydrogel. ‘Hieba’ demonstrated similar patterns: 39,000 and 44,900, respectively. Application of organic fertilizer allowed to increase the net productivity of photosynthesis (g/m2 of dry matter per day) in all the varieties under study: 0.73 in ‘Ustia’ in the treatment without hydrogel (0.68 in the control treatment), 1.00 in ‘Kano’ (0.92 in the control treatment) and 0.62 in ‘Hieba’ (0.46 in the control treatment). Conclusions. On average for the years of the experiment, plants of ‘Ustia’ variety formed 5.6–5.7 g of seeds per plant. Both ‘Kano’ and ‘Ustia’ formed 8.6 g of seeds per plant when using growth regulator Vermystym-D on the background of fertilizer Parostok and 8.7 g of seeds per plant on the background of using hydrogel Aquasorb. Top dressing with growth regulator Agrostymulin ensured individual plant productivity at the level of 8.7 and 8.5 g of seeds per plant, respectively.

Purpose. To determine the manifestation of biometric features of corn hybrids of various FAO groups and find out their relationship with grain yield when grown under drip irrigation in the Southern Steppe of Ukraine. Methods. Field, laboratory, mathematical and statistical. Result. Corn crops treatment with micronutrients had a positive effect on the height of hybrids in some phases of growth and development. The greatest influence on growth processes was caused by complex microfertilizer Avatar-1; it provided a growth in plant height as compared to the untreated control, by 1–7 cm. The use of Nutrimix microfertilizer, in general according to the variants of the experiment, influenced growth processes minimally (acceleration in phases of growth and development of the agriculture crop was 1–3 cm). Plants of the mid-late ‘Chonhar’ hybrid (FAO 420) were the highest throughout the growing season among the studied corn genotypes. This figure reached a maximum in the stage of milky ripeness when plants were treated with Avatar-1 – 267 cm. It was revealed that there is a close correlation between plant height and grain yield. Conclusions. The ratio of the height of hybrid plants by groups of ripeness and level of productivity showed that for medium-early groups in the phase of linear growth termination the optimum height was 240–250 cm, in this case grain yield was 11.2–11.5 t/ha, for the middle-ripening group – 255–257 cm with a grain yield of 11.8–12.1 t/ha. For mid-late maturity hybrids the optimum plant height for high yields grain (more than 13 t/ha) was in the range from 265 to 270 cm. The optimum height of plants and the maximum yield can be achieved under irrigation using corn hybrids of the corresponding groups of ripeness and the use of complex micronutrients.
