Cell migration plays a vital role in both health and disease. It is driven by reorganization of the actin cytoskeleton, which is regulated by actin-binding proteins cofilin and profilin. Stress-inducible phosphoprotein 1 (STIP1) is a well-described co-chaperone of the Hsp90 chaperone system, and our findings identify a potential regulatory role of STIP1 in actin dynamics. We show that STIP1 can be isolated in complex with actin and Hsp90 from HEK293T cells and directly interacts with actin in vitro via the C-terminal TPR2AB-DP2 domain of STIP1, potentially due to a region spanning two putative actin-binding motifs. We found that STIP1 could stimulate the in vitro ATPase activity of actin, suggesting a potential role in the modulation of F-actin formation. Interestingly, while STIP1 depletion in HEK293T cells had no major effect on total actin levels, it led to increased nuclear accumulation of actin, disorganization of F-actin structures, and an increase and decrease in cofilin and profilin levels, respectively. This study suggests that STIP1 regulates the cytoskeleton by interacting with actin, or via regulating the ratio of proteins known to affect actin dynamics.

Published: April 2020

The Arabidopsis genome comprises eighty genes encoding BTB (broad-complex, tramtrack, and bric-a-brac) family proteins that are characterized with the BTB domain and that potentially serve as substrate adaptors for cullin-based E3-ligases. In addition to the BTB domain, most BTB proteins also contain various other interaction motifs that probably act as target recognition elements. Here, we report three members of the BTB-A2 subfamily that distinctly only contain the BTB domain, BTB-A2.1, BTB-A2.2, and BTB-A2.3, that negatively regulates abscisic acid (ABA) signaling in Arabidopsis. BTB-A2.1, BTB-A2.2, and BTB-A2.3 encoded cytoplasm- and nucleus-localized proteins and displayed highly overlapping expression patterns in Arabidopsis tissues. Disruption of these three genes, but not single or double mutants, resulted in a decrease in ABA-induced inhibition of seed germination. Further analyses demonstrated the expression levels of these three genes were up-regulated by ABA, and their mutation increased ABA signalling. Importantly, protein-protein interaction assays showed that these three BTB-A2 proteins physically interacted with SnRK2.3. Moreover, biochemical and genetic assays indicated that BTB-A2.1, BTB-A2.2, and BTB-A2.3 decreased the stability of SnRK2.3 and attenuated the SnRK2.3 responsible for the ABA hypersensitive phenotype of seed germination. This report thus reveals that BTB-A2s serve as negative regulators for balancing the intensity of ABA signaling during seed germination.

Published: April 2020

HIV-1 infection is frequently associated with low bone density, which can progress to osteoporosis leading to a high risk of fractures. Only a few mechanisms have been proposed to explain the enhanced osteolysis in the context of HIV-1 infection. As macrophages are involved in bone homeostasis and are critical host cells for HIV-1, we asked whether HIV-1-infected macrophages could participate in bone degradation. Upon infection, human macrophages acquired some osteoclast features: they became multinucleated, upregulated the osteoclast markers RhoE and β3 integrin, and organized their podosomes as ring superstructures resembling osteoclast sealing zones. However, HIV-1-infected macrophages were not fully differentiated in osteoclasts as they did not upregulate NFATc-1 transcription factor and were unable to degrade bone. Investigating whether infected macrophages participate indirectly to virus-induced osteolysis, we showed that they produce RANK-L, the key osteoclastogenic cytokine. RANK-L secreted by HIV-1-infected macrophages was not sufficient to stimulate multinucleation, but promoted the protease-dependent migration of osteoclast precursors. In conclusion, we propose that, by stimulating RANK-L secretion, HIV-1-infected macrophages contribute to create a microenvironment that favors the recruitment of osteoclasts, participating in bone disorders observed in HIV-1 infected patients.
Functional Analysis of Differentially Expressed Acetylated Spermatozoal Proteins in Infertile Men with Unilateral and Bilateral Varicocele
Authors: Panner Selvam Manesh Kumar , Samanta Luna , Agarwal Ashok
Published: April 2020

Sperm proteins undergo post-translational modifications, such as phosphorylation, acetylation, and ubiquitination, which in turn play a key role in determining their fertilizing ability. In the current study, we examined the sperm proteome of men with unilateral and bilateral varicocele to identify the key proteins affected by acetylation to gain an insight into the difference in the severity of affected sperm function in the latter. An LTQ-Orbitrap Elite hybrid mass spectrometer system was used to profile the sperm proteome in pooled unilateral and bilateral varicocele patients. Bioinformatics database and tools, such as UniProtKB, Ingenuity Pathway Analysis Software (IPA) and Metacore, were used to identify the differentially expressed proteins (DEPs) involved in the acetylation process. A total of 135 DEPs in the spermatozoa of unilateral and bilateral varicocele patients were found to be affected by acetylation. The majority of these DEPs found were regulated by key transcription factors such as androgen receptor, p53, and NRF2. Furthermore, the DEPs predicted to be affected by the acetylation process were associated with fertilization, acrosome reaction, mitochondrial dysfunction and oxidative stress. Aberrant expression of proteins and their differential acetylation process may affect the normal physiological functions of spermatozoa. Protein–protein interactions identified dysregulation of the proteasome complex in the bilateral varicocele group. Damage to the proteasome complex may result in aggregation of the misfolded proteins, which in turn increase sperm DNA damage and apoptosis in patients with bilateral varicocele.
Soft Open Bases and a Novel Construction of Soft Topologies from Bases for Topologies
Authors: Alcantud José Carlos R.
Published: April 2020

Soft topology studies a structure on the collection of all soft sets on a given set of alternatives (the relevant attributes being fixed). It is directly inspired by the axioms of a topological space. This paper contributes to the theoretical bases of soft topology in various ways. We extend a general construction of soft topologies from topologies on the set of alternatives in two different directions. An extensive discussion with criteria about what a soft counterpart of “topological separability” should satisfy is also given. The interactions of the properties that arise with separability, and of second-countability and its soft counterpart, are studied under the general mechanisms that generate soft topological spaces. The first non-trivial examples of soft second-countable soft topological spaces are produced as a consequence.

Published: April 2020

Long-term intake of a ketogenic diet enhances utilization of ketone bodies, a particularly energy-efficient substrate, during exercise. However, physiological adaptation to an extremely low-carbohydrate diet has been shown to upregulate pyruvate dehydrogenase kinase 4 (PDK4, a negative regulator of glycolytic flux) content in skeletal muscle, resulting in impaired high-intensity exercise capacity. This study aimed to examine the effects of a long-term ketogenic diet containing medium-chain triglycerides (MCTs) on endurance training-induced adaptations in ketolytic and glycolytic enzymes of rat skeletal muscle. Male Sprague-Dawley rats were placed on either a standard diet (CON), a long-chain triglyceride-containing ketogenic diet (LKD), or an MCT-containing ketogenic diet (MKD). Half the rats in each group performed a 2-h swimming exercise, 5 days a week, for 8 weeks. Endurance training significantly increased 3-oxoacid CoA transferase (OXCT, a ketolytic enzyme) protein content in epitrochlearis muscle tissue, and MKD intake additively enhanced endurance training–induced increases in OXCT protein content. LKD consumption substantially increased muscle PDK4 protein level. However, such PDK4 increases were not observed in the MKD-fed rats. In conclusion, long-term intake of ketogenic diets containing MCTs may additively enhance endurance training–induced increases in ketolytic capacity in skeletal muscle without exerting inhibitory effects on carbohydrate metabolism.

Published: April 2020

After relative erythropoietin deficiency, iron deficiency is the second most important contributing factor for anemia in chronic kidney disease (CKD) patients. Iron supplementation is a crucial part of the treatment of anemia in CKD patients, and intravenous (IV) iron supplementation is considered to be superior to per os (PO) iron supplementation. The differences between the available formulations are poorly characterized. This report presents results from pairwise and network meta-analyses carried out after a comprehensive search in sources of published and unpublished studies, according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) recommendations (International prospective register of systematic reviews PROSPERO reference ID: CRD42020148155). Meta-analytic calculations were performed for the outcome of non-response to iron supplementation (i.e., hemoglobin (Hgb) increase of <0.5–1.0 g/dL, or initiation/intensification of erythropoiesis-stimulating agent (ESA) therapy, or increase/change of iron supplement, or requirements of blood transfusion). A total of 34 randomized controlled trials (RCT) were identified, providing numerical data for analyses covering 93.7% (n = 10.097) of the total study population. At the network level, iron supplementation seems to have a more protective effect against the outcome of non-response before the start of dialysis than once dialysis is initiated, and some preparations seem to be more potent (e.g., ferumoxytol, ferric carboxymaltose), compared to the rest of iron supplements assessed (surface under the cumulative ranking area (SUCRA) > 0.8). This study provides parameters for adequately following-up patients requiring iron supplementation, by presenting the most performing preparations, and, indirectly, by making it possible to identify good responders among all patients treated with these medicines.
The role of digital personal photography: a theoretical exploration with Deleuze-Guattari approach
Authors: Sun Zhen
Published: April 2020

The innovations of digital photography are transforming people’s experiences of producing, manipulating, sharing, and using their personal photographic images. The essentialist and representational dualistic viewpoints of photography that were initially developed in the era of the Daguerreotype appear no longer tenable in the contemporary photography era. This study focuses on the ever-changing role of personal photographic images in the three typical photography events, i.e., the selfie production, the real-time beautified video sharing on the social media, and the production of deepfake AI face-swaps. The study is inspired by the Deleuze-Guattari’s conceptual framework that is mainly composed of the concepts of minor literature, assemblage, becoming, and de/re-territorialization, and defines personal photographic images as both an assemblage and a constitutive part of larger assemblages, i.e., personal photograph production and usage events. The tetravalent model of assemblages is used as a major analysis toolkit to achieve the research purpose. A thorough analysis and discussion shows the material and expressive components that compose different sizes of assemblages and the emergent capacities. It also discloses how digital photography apps play as a line of flight to de/re-territorialize the presumed representational association between individuals and their photographic images. The images have become one of the multiplicities or becoming of individuals, either interacting with individuals, acting on individuals, or extending individuals’ disembodied experiences. This study seeks to develop alternative theoretical lenses on the role of digital personal photography in everyday life and the rhizomatic experiences that it generates.
Media Evolution, “Double-edged Sword” Technology and Active Spectatorship: investigating “Desktop Film” from media ecology perspective
Authors: Yang Jing
Published: April 2020

Desktop film or computer screen film is a film subgenre with all events and actions taking place on a screen of a computer and using the protagonist’s first-person perspective, exemplified by The Den (2013), Open Windows(2014), Unfriended (2014), Unfriended: Dark Web (2018), Profile (2018) and Searching(2018). This paper mainly focuses on the desktop films with the theoretical framework of “Media Ecology”, aiming to investigate how the desktop film evolves and interacts with new media, digital technology, while influencing communication and spectatorship. Firstly, this paper discusses the evolution of cinema, which evolves through the interaction, co-existence and convergence with other media, as well as corresponds to the anthropotropic trend. Secondly, this paper investigates the digital media and technology in desktop films. “Desktop films” create cyberspaces and reproduce people’s virtual lives, revealing the influences of media technology, which is considered as a double-edged sword. Thirdly, this paper analyzes how desktop film exerts impacts on cinematic communication, while reshaping the spectatorship and audience’s viewing mechanism. “Desktop films” are suitable to be watched on computer, thus making audiences become active and have more autonomy.

"War Epidemiology" Versus "Peace Epidemiology": A Personal View
Authors: Rezaeian Mohsen
Published: April 2020

Epidemiology can be considered as a responsible public health science the aim of which is to control health problems. One of the most important public health problems is "war". The aim of the present paper, therefore, is threefold: firstly, to determine to what extent war has been investigated from an epidemiological point of view; secondly, what the definition and scope of "war epidemiology" would be; and thirdly, if it would be possible to introduce a new branch of epidemiology entitled "peace epidemiology". In the present study, I have tried to fulfill the aims of the study based on my experiences in war and peace epidemiology and also by reviewing the most relevant websites, documents and papers. Evidence suggests that enough epidemiological studies have not been carried out to determine the sheer public health consequences of war. "War epidemiology" can be defined as "the study of the distribution and determinants of war-related events in specified populations, and the application of this study to the control of war". "Peace epidemiology" is a new branch of epidemiology which "highlights how peace could positively shape our world". Epidemiologists need to produce more scientific evidence about the negative public health consequences of wars and also the positive public health consequences of peace. The ultimate aim of "war epidemiology" is to control war, usually by secondary and tertiary prevention activities. However, the ultimate aim of "peace epidemiology" is to reinforce peace by primary and/or primordial prevention activities.
Chalk depth structure maps, Central to Eastern North Sea, Denmark
Authors: Vejbæk Ole V. , Bidstrup Torben , Britze Peter , Erlström Mikael , Rasmussen Erik S. , Sivhed Ulf
Published: April 2020

The Upper Cretaceous – Danian chalk may be considered to be the economically most important rock type in Denmark. Onshore it constitutes an important groundwater aquifer and it is also quarried for e.g. building materials and paper production. Offshore the chalk reservoirs contain more than 80% of the oil and gas produced in Denmark (Fig. 1). During the last few years efforts have therefore been made to map this important succession in the Danish and adjoining areas (Vejbæk et al. 2003). The stratigraphic interval mapped comprises the Chalk Group of Cenomanian to Danian ages and its stratigraphically equivalent units (Fig. 2). The north-eastern limit of the Chalk Group is determined by Neogene erosion. The limits of the map to the west and south were mainly determined by the amount of available data.
Are Carboniferous coals from the Danish North Sea oil-prone?
Authors: Petersen Henrik I. , Nytoft Hans P.
Published: April 2020

The Central Graben in the North Sea is a mature petroleum province with Upper Jurassic – lowermost Cretaceous marine shale of the Kimmeridge Clay Formation and equivalents as the principal source rock, and Upper Cretaceous chalk as the main reservoirs. However, increasing oil prices and developments in drilling technologies have made deeper plays depending on older source rocks increasingly attractive. In recent years exploration activities have therefore also been directed towards deeper clastic plays where Palaeozoic deposits may act as petroleum source rocks. Carboniferous coaly sections are the most obvious source rock candidates. The gas fields of the major gas province in the southern North Sea and North-West Europe are sourced from the thick Upper Carboniferous Coal Measures, which contain hundreds of coal seams (Drozdzewski 1993; Lokhorst 1998; Gautier 2003). North of the gas province Upper Carboni-ferous coal-bearing strata occur onshore in northern England and in Scotland, but offshore in the North Sea area they have been removed by erosion. However, Lower Carboniferous strata are present offshore and have been drilled in the Witch Ground Graben and in the north-eastern part of the Forth Approaches Basin (Fig. 1A), where most of the Lower Carboniferous sediments are assigned to the sandstone/shale-dominated Tayport Formation and to the coal-bearing Firth Coal Formation (Bruce & Stemmerik 2003). Highly oil-prone Lower Carboniferous lacustrine oil shales occur onshore in the Midland Valley, Scotland, but they have only been drilled by a single well off shore and seem not to be regionally distributed (Parnell 1988). In the southern part of the Norwegian and UK Central Graben and in the Danish Central Graben a total of only nine wells have encountered Lower Carboniferous strata, and while they may have a widespread occurrence (Fig. 1B; Bruce & Stemmerik 2003) their distribution is poorly constrained in this area. The nearly 6000 m deep Svane-1/1A well (Fig. 1B) in the Tail End Graben encountered gas and condensate at depths of 5400–5900 m, which based on carbon isotope values may have a Carboniferous source (Ohm et al. 2006). In the light of this the source rock potential of the Lower Carboniferous coals in the Gert-2 well (Fig. 1C) has recently been assessed (Petersen & Nytoft 2007).

The prime objective of this research is to develop a comprehensive framework for the static analysis of crane-dependent climbing formwork system. In this research, one of the climbing formwork systems that are commonly used for the construction of high-rise buildings known as crane-dependent is contemplated. Initially, suitable design intends of the climbing formwork system are discerned from the literatures and formwork technical reports. Additionally, various other factors influencing the analysis of the climbing formwork system are taken from the real-time construction projects. Using these information a suitable 3D finite element model of the climbing formwork system is developed. The 3D model is then analysed using a superior finite element program. The result shows significant variations in terms of deflections and stress contours. Notwithstanding the application of the real-time parameters for the analysis of climbing formwork system, the results obtained are haphazard. To overcome these shortcomings and to apprehend the situation of lack of codal provisions for the analysis of climbing formwork, a sophisticated soft computing methodology, known as Genetic algorithm is trailblazed. The optimal parameters obtained from the Genetic algorithm is then used to formulate the modified 3D finite element model. The results of the modified 3D finite element model depicts the actual behaviour of the climbing formwork system in the real-time scenario. This research portraits the comprehensive procedure for the analysis of climbing formwork systems.

Published: April 2020

An efficient data hiding method is proposed in the smart cyber-attacks such as data theft, virus attacks on the transmitting of whole confidential data, partial confidential data via private and government networks. The transmitting data over the internet is one of the better solutions to make a work easy and fast even though protecting data from the smart hackers is vital role in the cyber-crimes. There are various protection techniques of confidential data like digital watermarking, digital signals with embedding data into images, audio and videos. The existing watermarking techniques using RSA is a time consuming process for number of iterations to be performed even in signal decryption of image. These complexities of iterations to be overcome by the Least Significant Bits, DWT transformation and Arnold transformation were failing in all aspects of security requirements. The proposed method of reversible data hiding has an efficient encryption in medical images, health care image and data transmitting in various organizations.

In most of the time, the real life phenomena are uncertain. Due to the uncertain nature, consideration of some exact values or definite conditions may cause errors in the solution process. The fluid flow problems are also uncertain due to the presence of various imprecise parameters, variables and conditions. Here, an MHD fluid flow over an exponentially accelerated inclined plate is considered in fuzzy environment. Fuzzy set theory (FST) may help to overcome the uncertain nature of the fluid flow problems. The governing equations and the boundary conditions of the considered problem are fuzzified using the extension principle. The fuzzified governing equations along with the fuzzified boundary conditions are solved using the finite difference method (FDM) by developing suitable computer programming code in Python. The values of the different parameters and variables (initial values) are taken as triangular fuzzy number (TFN). −cut technique is used to find the results. The effects of the various involved parameters and on the velocity, temperature and concentration profile are presented graphically and discussed.

In the current study the process parameters for used cooking oil biodiesel production are optimized by using Design of Experiments (Taguchi technique) and validation experiments are carried out at the optimized parameters to cross verify the results obtained. A specially designed equipment which can maintain the exact conditions required for optimization is used. This equipment is microcontroller operated and does not require any human intervention to maintain the accurate temperature, time and other parameters. By Taguchi strategy best yield acquired is by Molar ratio of A2 (1:9), Catalyst concentration of B3 (1.00%), Reaction temperature of C2 (60ºC), Reaction time of D3 (120 min). The approval trial was completed for the results and the yield is observed to be 93.25%, which resulted in improvement of up to 15% yield as compared to that of crude method.

That allows equipment to be connected at anytime with anything rather using network and service. By 2020 there will be 50 to 100 billion devices connected to Internet and will generate heavy data that is to be analyzed for knowledge mining is a forecast. The data collected from individual devices of IoT is not going to give sufficient information to perform any type of analysis like disaster management, sentiment analysis, and smart cities and on surveillance. Privacy and Security related research increasing from last few years. IoT generated data is very huge, and the existing mechanisms like k- anonymity, l-diversity and differential privacy were not able to address these personal privacy issues because the Internet of Things Era is more vulnerable than the Internet Era [10][20]. To solve the personal privacy related problems researchers and IT professionals have to pay more attention to derive policies and to address the key issues of personal privacy preservation, so the utility and trade off will be increased to the Internet of Things applications. Personal Privacy Preserving Data Publication (PPPDP) is the area where the problems are identified and fixed in this IoT Era to ensure better personal privacy.

The project represents an automated attendance system based on face recognition using discriminative local binary pattern and local directional pattern descriptors. The proposed system involves face detection, Features extraction and matching. The face detection is to detect faces based on Viola Jones algorithm . In feature extraction stage, the discriminative local binary pattern is used for different object texture feature extraction process. The proposed method with new features retain the contrast information of image patterns. The Facial recognition (or face recognition) is a type of biometric application that can identify a specific individual in a digital image by analyzing and comparing patterns based on the data stored in database. Smart attendance is a real time face recognition used for handling day to day activities of the employees and students. In manual attendance system there are several issues like fake attendance and mistakenly marked absent by carelessness of the faculty/teachers/lectures. In order to overcome these problems we are using this smart attendance system. Here multiple faces are detected and recognized with trained with various features. The automated face attendance marking system gives accurate performance.

The present paper investigates the synthesizing routes and best method to explain the hot deformation behavior of novel Al-x wt.% Zn alloys (x = 0, 10, 20, 30, 40 and 50 wt.%). Based on several synthesizing routes, it was studied that the liquid metallurgy route followed by squeeze casting and extrusion is the best manufacturing method of the novel Al-Zn castings. These novel Al-Zn casting alloys would give more benefits as it possesses lower value of melting temperature; which is best suited for die-casting parts. To explore the mechanical behavior of Al-Zn castings, hot deformation studies by developing the processing map is best method by which complete information related to these alloys bahaviour could be obtained. From the literature, it was found that the hot workability behavior can be examined by developing the processing map using dynamic material modelling (DMM) and constitutive models (sine-hyperbolic Arrhenius kinetic rate equation). The step by step procedure to be followed for hot deformation analysis was explained in this work. From this analysis, the peak flow stress, stability region, instability region, power dissipation efficiency, activation energy and dynamic recrystallization region can be explored. In addition, as a pilot study related to these Al-Zn alloy, several castings, namely, pure Aluminium(Al), Al-10Zn, Al-20Zn, Al-30Zn, Al-40Zn, and Al-50Zn were successfully casted using electric furnace and then all these castings were squeezed followed by extruded to have improved densification. The hardness of casted samples was revealed that Al-40Zn casting exhibited a vicker’s hardness strength (VHS) of 1326 MPa which was 4 times higher than pure Al.
