Authors: Bartosz Miciñski , Bupebayeva Lyayla K. , Jan Miciñski , Stanisław Milewski
Published: November 2020

Background: Research studies conducted with the involvement of various molecular techniques have demonstrated that ovomucoid, a protein found in chicken egg whites, is also a major food allergen. Many studies have shown that about 40% of patients with allergy against egg proteins were sensitive to ovomucoid. Egg whites are popularly used in the world to enhance the nutritional value of food products (as additives in pastry, meats, sauces, salads and creams) and the production and use of eggs in the world is increasing. Their complete elimination from the diet is highly challenging. Ovomucoid comprises 186 amino acids and has antibacterial properties, and inhibits the activity of microbial enzymes. In this experiment, chicken egg ovomucoid was isolated and polyclonal antibodies were obtained by immunizing a rabbit with the ovomucoid solution to analyze the effect of non-enzymatic glycosylation on the physicochemical properties and immunoreactivity of the studied ovomucoid.
Methods: The study analyzed ovomucoid – a protein isolated from the whites of the analyzed eggs. Ovomucoid was isolated by the method proposed by Roy et al. (2003). The next procedure was rabbit immunization. Polyclonal antibodies were obtained by subcutaneously immunizing a male rabbit with a solution of chicken egg glycated or native (a 100 ìg protein dose) in 1 ml PBS with pH 7.2. All measurements were performed in triplicate. The Fisher’s test was conducted to analyze variations in immunoreactivity and changes in glycation degree.
Result: Research has shown that it is needed to research the toxicity of proteins, in this case ovomucoid. Glycation may be recommended as a way to reduce or inhibit immunoreactivity. In case of allergies, such action is necessary and purposeful and it is essential to choose such reaction conditions which do not cause products harmful to human’s health.

Published: November 2020

Background: Vitamin A has potentially harmful effects on the development of chick embryos even at very low dose concentration. Vitamin A different doses cause embryotoxic and teratogenic effects on the developing of the chick embryo. Hence, due to teratogenicity of this vitamin it can be used with utmost caution during pregnancy.
Methods: Fertile chicken eggs (obtained from local hatchery) were injected with three doses of Vitamin A (15 IU/ml, 30 IU/ml, 75 IU/ml) into the center of the egg yolk. Morphometric parameters as mortality rate, body weight (g), crown rump length (mm) of embryo and Frequency % of different anomalies gross malformations were measured. Whole chicken samples were taken by 4th, 8th and 18th incubation day. Daam, Hox and Tbx genes expression profile were analyzed.
Result: Dose-dependent defects and embryo lethality in the chick embryos developed when exposed to higher concentrations. Our study record for the first time the duplication in the heart, brain and eye. Also showed duplication of the neck forming S-shaped showed in some malformed chick embryos. The three investigated genes showed different fluctuations confirming the malformations detected.

Published: November 2020

Background: The present study was conducted at Livestock farm complex, TANUVAS, Chennai (India) with the objective of comparing the proximate composition and meat characters of three desi chicken breeds viz., Kadaknath, Nicobari Black and Naked Neck chicken.
Methods: For this purpose, 60 adult birds (20 each) were maintained on littered floor in separate pens under optimal management conditions. The birds were fed with ad libitum balanced broiler ration and slaughtered after 8 weeks by randomly selecting 6 birds from each breed.
Result: Laboratory analysis revealed that there was no significant difference (p>0.05) in the proximate composition of meats among the three native chicken breeds. The total ash content and calcium level was found to be higher in Nicobari Black chicken meat than other breeds and Naked Neck chicken showed the highest value of unsaturated fatty acid. There was significant difference (p less than 0.01) in the physical characters like pH, Water Holding Capacity (WHC), Shear Force Value (SFV), Extract Release Volume (ERV), Thiobarbituric Acid (TBA), Tyrosine Value (TV) texture profile analysis and hunter colour value among the three native breeds. These factors will help us to choose the right native desi breed for development of designer and value added meat products.

Published: November 2020

Background: Notable advancements in the selection indices have led to the development of exceptional breeding strategies, which have eventually led to the selection of elite dairy animals. The comparison of trends is facilitated by their estimation which permit the assessment of progress in a particular trait. The purpose of this study was to investigate genetic trends in economic traits of Murrah buffaloes, which is predominantly present as a high milk producer using the regression method. The study was designed to estimate the phenotypic, genetic and environmental trends, which represent the changes accrued over time and hence, determines the efficiency of breeding programme.
Methods: The present study was conducted on 659 Murrah buffaloes, sired by 188 bulls, over a period of 27 years (1991-2017). The economic traits studied were first lactation milk yield (FLMY), first lactation length (FLL), age at first calving (AFC), first calving interval (FCI), first service period (FSP) and first dry period (FDP). The phenotypic trends were obtained as regression of population performance on year and the genetic trends were obtained by Smith method I and II.
Result: The results revealed that the phenotypic trends obtained were significant and desirable for all the traits except for first lactation length, which was non-significant. The standard errors obtained by Smith method-I were higher than those obtained from method-II. As the Smith method-II avoids year to year fluctuations in the environment and those of contemporaries, it gives more realistic estimate as compared to the first method with lower standard error.

Authors: Singh Randhir , Randhawa S. N.S. , Randhawa C. S. , Chhabra Sushma , Chand Naimi
Published: November 2020

Background: Use of novel biomarkers is the need of hour for prediction and early diagnosis of bovine production diseases such as hepatic lipidosis (HL). Liver ultrasonography and estimation of liver specific enzymes activities have been successfully used for diagnosis of HL. However, use of inflammatory mediator like tumor necrosis factor-á (TNF–á) or acute phase proteins (APPs) like C reactive protein (CRP), serum amyloid A (SAA) and haptoglobin (Hp) as biomarkers of HL has not been elucidated. The present study was therefore designed to evaluate liver ultrasonography and serum APPs concentrations as early predictive biomarkers of bovine HL.
Methods: This study included one hundred one (101) multiparous crossbred cows in advanced pregnancy from dairy farm in Punjab, India. The cows were grouped according to their transition stage i.e., Far off dry (FOD), close up dry (CUD) and Fresh (F). Liver ultrasonography along with hemato-biochemical analysis and estimation of acute phase proteins was carried out during different stages of transition period.
Result: This study included 101 cows, of which 71 (70.3%) had ultrasonographic features of normal liver and 30 (29.7%) had ultrasonographic features of HL (Grade I, 10 cows; Grade II, 12 cows; Grade III, 8 cows). Cows with HL had significantly lower levels of hemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), total plasma protein (TPP), glucose, total calcium (Ca) and zinc (Zn) and significantly higher levels of plasma urea nitrogen (PUN), non-esterified fatty acid (NEFA), beta hydroxyl butyric acid (BHBA), alkaline phosphatase (ALP), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), glutamate dehydrogenase (GDH), lactate dehydrogenase (LDH), TNF–á, CRP, SAA and Hp compared to the negative controls. The APPs, liver ultrasonography, liver enzymes along with NEFA and BHBA could be used as biomarkers for prediction and early diagnosis of HL in cows.

Published: November 2020

Background: Hypothalamus is an integral part of the hypothalamo-hypophyseal ovarian axis. It contains several small nuclei that have been implicated in several specialized functions. It is the master endocrine gland because it regulates the activity of the pituitary. The present investigation was planned to elucidate the histomorphological details of different nuclei in the hypothalamus of Indian buffaloes.
Methods: The hypothalami of buffaloes (n =52) were collected from local abattoirs and Teaching Veterinary Clinical Complex, GADVASU, Ludhiana. The tissue samples were collected from three levels i.e. the supraoptic, tuberal and the mamillary region of the hypothalamus and processed for paraffin sectioning and the sections were stained with various stains for histomorphological studies.
Result: The well-defined cell groups or nuclei were identified both in the coronal and sagittal sections of the hypothalamus in all the reproductive phases. Eight nuclei were distinctly recognized in buffalo hypothalamus at three levels in the coronal sections of the hypothalamus. At the level of optic chiasma, the nuclei were paraventricular nucleus (PVN), supraoptic nucleus (SON) and preopticnucleus (PON); at the tuberal region, there were arcuate nucleus (AN) and ventromedial nucleus (VMN) and at the mammillary region, the lateral mammillary nucleus (LMN), medial mammillary nucleus (MMN) and posterior hypothalamic nucleus (PHN) were identified. Most of the nuclei consisted of a loose or compact heterogeneous collection of neurons. The neurons of the different nuclei were of variable shape. The cytoplasm contained a varied amount of Nissl material. The neurosecretory substance was peripheral in position. Small to large-sized blood vessels were observed in between the neuronal substance. The size of the neurons varied during different stages of reproduction.

Authors: Mirsepasi-Lauridsen Hengameh Chloé , Struve Carsten , Petersen Andreas Munk , Krogfelt Karen Angeliki
Published: November 2020

Background: Phylogroup B2 Escherichia coli have been associated with Ulcerative Colitis (UC). In this study, we aimed to compare colonization with the UC-associated E. coli p19A in different mice strains, to investigate the role of alpha hemolysin in a UC mouse model. Methods: In this study, Sigirr -/- and C57BL/6 mice were chosen, and UC was induced by adding Dextran Sulfate Sodium (DSS) to the drinking water. The mice were pre-treated with ciprofloxacin. p19A expressing luminescence and GFP, alpha-hemolysin knock out p19A-∆hlyI II, and non-pathogenic lab E. coli DH10B were cultured in LB broth, and orally gavaged into the mice. Colonization with p19A WT was visualized using an in-vivo imaging system. Results: p19A WT colonized the colon, ileum, Peyer’s patches, liver, and spleen of infected C57BL/6 and Sigirr -/- mice. A total of 99% of the p19A WT infected C57BL/6 mice and 29% of the p19A WT infected Sigirr -/- mice survived to the 4th post infection day. Conclusion: UC-associated E. coli p19A WT colonized the intestines of DSS-treated mice and caused extra-intestinal infection. Hemolysin is an important factor in this pathogenesis, since isogenic hemolysin mutants did not cause the same inflammation.

Published: November 2020

Convolutional Neural Networks combined with autonomous drones are increasingly seen as enablers of partially automating the aircraft maintenance visual inspection process. Such an innovative concept can have a significant impact on aircraft operations. Through supporting aircraft maintenance engineers detect and classify a wide range of defects, the time spent on inspection can significantly be reduced. Examples of defects that can be automatically detected include aircraft dents, paint defects, cracks and holes, and lightning strike damage. Additionally, this concept could also increase the accuracy of damage detection and reduce the number of aircraft inspection incidents related to human factors like fatigue and time pressure. In our previous work, we have applied a recent Convolutional Neural Network architecture known by MASK R-CNN to detect aircraft dents. MASK-RCNN was chosen because it enables the detection of multiple objects in an image while simultaneously generating a segmentation mask for each instance. The previously obtained F1 and F2 scores were 62.67% and 59.35% respectively. This paper extends the previous work by applying different techniques to improve and evaluate prediction performance experimentally. The approaches uses include (1) Balancing the original dataset by adding images without dents; (2) Increasing data homogeneity by focusing on wing images only; (3) Exploring the potential of three augmentation techniques in improving model performance namely flipping, rotating, and blurring; and (4) using a pre-classifier in combination with MASK R-CNN. The results show that a hybrid approache combining MASK R-CNN and augmentation techniques leads to an improved performance with an F1 score of (67.50%) and F2 score of (66.37%)
Engineering Self-Organized Criticality in Living Cells

Published: November 2020

Complex dynamical fluctuations, from molecular noise within cells, collective intelligence, brain dynamics or computer traffic have been shown to display noisy behaviour consistent with a critical state between order and disorder. Living close to the critical point can have a number of adaptive advantages and it has been conjectured that evolution could select (and even tend to) these critical states. One way of approaching such state is by means of so-called self-organized criticality (SOC) where the system poises itself close to the critical point. Is this the case of living cells? It is difficult to test this idea given the enormous dimensionality associated with gene and metabolic webs. In this paper, we present an alternative approach: to engineer synthetic gene networks displaying SOC behaviour. This is achieved by exploiting the presence of a saturation (congestion) phenomenon of the ClpXP protein degradation machinery in E. coli cells. Using a feedback design that detects and then reduces ClpXP congestion, a {\em critical motif} is built from a two-gene network system, where SOC can be successfully implemented. Both deterministic and stochastic models are used, consistently supporting the presence of criticality in intracellular traffic. The potential implications for both cellular dynamics and designed intracellular noise are discussed.

Abstract: Insecure and portable devices in the smart city’s Internet of Things (IoT) network are increasing at an incredible rate. Various distributed and centralized platforms against cyber-attacks have been implemented in recent years, but these platforms are inefficient due to their constrained levels of storage, high energy consumption, the central point of failure, underutilized resources, high latency, and etc. In addition, the current architecture confronts the problems of scalability, flexibility, complexity, monitoring, managing & collecting of IoT data, and defend against cyber-threats. To address these issues, the author presents distributed and decentralized Blockchain-Software Defined Networking (SDN) based energy-optimized architecture for IoT in smart cities. Thus, SDN continuous observing, controlling, managing IoT devices activities and detect possible attacks in the network; Blockchain provides adequate security & privacy against cyber-attacks, reduces the central point of failure issues; Network Function Virtualization (NFV) are used to saving energy, load balancing, as well as increasing the lifetime of the entire network. Also, we introduce a Cluster Head Selection (CHS) algorithm to reduce the energy consumption in the presented model. Finally, we analyze the performance using various parameters (e.g. throughput, response time, gas consumption, communication overhead) and demonstrating the result that provides higher throughput, lower response time, lower gas consumption than existing works for smart cities.

The data was analyzed by applying The Pearson product moment correlation, t-Test, and descriptive analysis. The results indicated that the anxiety level while reading had varied values from moderate to high most of the respondents in the test were found to be in the moderate anxiety group. In addition, a notable negative relationship was found to be existing between the FLRA and the reading proficiency. The association existing between the foreign language reading anxiety and the group field was identified in this study. Analyzing the concept considering the gender, the female students were identified to experience more anxiety compared to the male students involved in the study. The findings of this study are advantageous to the language teachers and the curriculum planners too. It enables them to decrease the deteriorating and weakening factors in the classroom and thereby improve the reading ability of the language learners’.  Reducing the reading anxiety amongst the learners can be achieved by exposing the language learners to understandable reading texts and familiarize them with cultural texts. This in turn develops the learners’ self-confidence and motivates them to be better readers.
LAS POETAS TAMBIÉN VIAJAN AL PARNASO. TRADICIÓN LITERARIA Y DIFERENCIA DE GÉNERO EN LA POESÍA DIECIOCHESCA
Authors: Establier Pérez Helena
Published: November 2020

La visita al Parnaso en clave femenina es un motivo que comparten en sus composiciones varias de las poetas españolas de las últimas décadas del XVIII y del período de entre siglos, como Clara Jara de Soto, Gertrudis de Hore y María Rosa de Gálvez. Este trabajo se centra en el estudio de este motivo de amplia tradición poética en varias composiciones de las tres autoras citadas donde adquiere matices novedosos, contribuyendo así a perfilar las vías por las que estas expresan en clave poética su conciencia de excepcionalidad y de marginalidad dentro del espacio literario de su tiempo.
INGENIO Y MUJER EN EL DISCURSO HEGEMÓNICO Y HETERÓNOMO DE LA TEMPRANA MODERNIDAD ESPAÑOLA
Authors: Vijarra René Aldo
Published: November 2020

Durante el siglo XVI, una serie de dispositivos discursivos hegemónicos construyeron una representación de los sujetos y esos discursos tuvieron una amplia difusión e influencia en la centuria siguiente. El Examen de ingenios para las ciencias (1575) de Juan Huarte de San Juan fue uno de esos discursos performativos que delimitó las competencias y funciones de los hombres teniendo en cuenta el ingenio de cada quien. Si bien la mujer no fue el tema del tratado, no estuvo ausente de la mirada del médico navarro, quien ofreció su propia perspectiva. Por otro lado, y en franca disidencia con estas opiniones, dos mujeres, María de Zayas y Mariana de Carvajal, desde el campo literario y con una posición excéntrica, manifestaron en diferentes obras su resistencia a esos principios biológicos y universales a través de la voz de las enunciadoras de los paratextos y de la voz y accionar de los personajes.
SOR JUANA INÉS DE LA CRUZ HACE SUDAR LAS PRENSAS ESPAÑOLAS
Authors: Fumagalli Carla Anabella
Published: November 2020

En este trabajo recorreremos las ediciones de la obra de sor Juana Inés de la Cruz con el objetivo de dar cuenta de algunos modos de legitimación de su autoría, de su obra y de sus publicaciones. Especialmente, atenderemos a los preliminares y paratextos que se señalan entre sí, no solo al interior de un libro, sino entre impresiones para indicar los recursos discursivos y editoriales que construyen la obra sorjuanina.
MARÍA ARACIL Y SACHA SAVAROF: DOS PROTAGONISTAS BAROJIANAS
Authors: Orts Agulló Eva
Published: November 2020

Pío Baroja ha sido considerado por la crítica como un hombre misógino y un escritor que no se ha detenido en los personajes femeninos. Este artículo pretende destacar el importante papel de dos figuras femeninas que son, además, protagonistas de tres novelas. Estas heroínas no son figuras estáticas sino que, como los demás héroes barojianos, van rodando de un lugar a otro. Baroja dedica los primeros capítulos para explicar cómo el medio en el que crecen determina su personalidad y, en la elaboración de la joven estudiante de Medicina Sacha Savarof, se observa la influencia de Schopenhauer. En las novelas aparecen temas de interés para la mujer como la educación, la amistad femenina o el divorcio, lo que sitúa el pensamiento barojiano en la vanguardia del feminismo.
ANÁLISIS DE LA HEGEMONÍA DE LA POESÍA DE LA EXPERIENCIA EN ESPAÑA. Historia de un modelo lírico
Authors: Candón Ríos Fernando
Published: November 2020

El presente artículo analiza el contexto histórico, social y poético en el que se ha desarrollado el posicionamiento de los poetas de la experiencia como grupo hegemónico en el campo poético español. La singularidad de esta dominancia se encuentra en la duración de su hegemonía, ya que hasta ahora ningún otro colectivo había conseguido establecerse como grado referencial dentro de los estándares del canon poético durante un periodo temporal de treinta años. Su reconocimiento en la década de los noventa fue el comienzo de un fenómeno hasta ahora inaudito en el panorama español.
El erotismo y Rubén Darío, un recorrido teórico
Authors: Roldán Sabrina Nair
Published: November 2020

En el siguiente artículo hacemos un recorrido teórico de la categoría erotismo desde el texto clásico de Georges Bataille y otros textos conocidos para analizar la poesía de Rubén Darío. El erotismo y lo femenino en la poesía de Darío refuerzan un universo metapoético donde la referencia no es una mujer en particular sino la poesía misma.

Submarine topographic control on distribution of supercritical-flow deposits in lobe and related environments, middle Eocene, Jaca Basin, Spanish Pyrenees
Authors: Cornard Pauline H. , Pickering Kevin T.
Published: November 2020

Submarine lobe and related deposits are amongst the largest discrete sandbodies on Earth, and can be significant hydrocarbon reservoirs. In outcrop and core-based studies, tools such as analysis of bed-thickness and grain-size distributions have been used to improve the understanding of the composition and architecture of such sandbodies. Analysis of sediment-gravity-flow (SGF) processes have also proved to be a useful tool in understanding the evolution of submarine lobes. In this paper, based on outcrop studies of submarine lobe and related deposits in the middle Eocene Jaca Basin, Spanish Pyrenees, a revised interpretation of the depositional environments of the lobe and related deposits and a new model for their architectural evolution is presented. This model is based on an analysis of bed-thickness, grain-size distribution, and a qualitative and quantitative study of the distribution of supercritical-flow deposits (SFDs) in these environments. The interpretation of lobe and related environments is mainly based on sandstone content and the distribution of sedimentary facies. The main supercritical-flow sedimentary structures recognized in the Jaca Basin, are unstable and stable antidunes, upper plane beds and backset-laminated beds.

This study demonstrates that seafloor topography, strongly controlled by both syndepositional tectonics and the accumulation of mass-transport complexes, likely exerted a significant influence on lobe architecture and the distribution of SFDs. Local increase in bed thickness, together with a progressive decrease in grain size and little variation in the proportion of SFDs in proximal-to-distal and axial-to-lateral directions, can be explained by: i) an increase in basin confinement of the distal part of the Jaca Basin due to tectonically induced narrowing, ii) enhanced local lateral confinement due, at least in part, to “carbonate megaturbidites” present in the distal part of the Jaca Basin and creating topography. Thus, basin confinement is introduced as a new parameter playing a role on flow criticality. There is a decreasing proportion of SFDs between the submarine channels and canyons of the Ainsa Basin and the submarine lobes of the Jaca Basin, the last basin being the focus of this paper. This confirms previous studies showing that channel confinement and slope gradient likely played an important role in flow criticality.

Our objective was to obtain normal patellofemoral measurements so as to provide a reference for prosthetic design. Besides, the absolute values and indices of TT-TG distances are still controversial in clinical application. A better method to enable precise clinical applications is still needed.Methods:78 knees of 78 subjects without knee pathologies were included in this cross-sectional study. A CT scan was obtained from all subjects and three-dimensional knee models were constructed using Mimics and SolidWorks software. We measured and analyzed 19 parameters including TT-TG distance and dimensions and shapes of patella, femur, tibia, and trochlea. LASSO regression was used to predict the normal TT-TG distances.Results:The dimensional indexes, TT-TG distance, and femoral aspect ratio of the males were significantly larger than those of females (all P values <0.05). However, after controlling the bias from age, height, and weight, there were no significant differences in TT-TG distances, PAL, and anterior-posterior dimensions between genders (all P values >0.05). The Pearson correlation coefficients between the AFO and other indexes were consistently below 0.3, indicating a none or weak relationship. Similar results were observed for the SA and the Wiberg index. Using LASSO regression, we obtained four parameters to predict TT-TG distance (R2=0.5612, P<0.01) to achieve the optimal accuracy and convenience. Conclusion:The anterior-posterior dimensions of the females were thicker than those of males for the same medial-lateral dimensions. More attention should be paid to not only gender differences but individual differences, especially the anterior condyle and trochlea. Besides, this study provided a new method of predicting TT-TG distance to enable precise clinical diagnoses and guide the medial transfer of the tibial tuberosity.
