Interpretation of Action Potential Generation Mechanism in Cells by Potassium Channel "Origami Windmill" Model
Authors: sun zuodong
Published: September 2019

The mechanism of cell action potential was explained by using the principle of potassium channel "origami windmill" model. It is inferred that ion channels should include at least two categories: One kind of channel is "special ion channel", its structure is like an origami windmill model. All cations passing through this channel rotate into the interior from one-way, only in and no out. Compared with K+, they have two states of "open" and "closed", When they are "open", their aperture is not less than K+ diameter. When "closed", their aperture is smaller than K+ diameter, but not smaller than Na+ diameter. The other channel is the "universal ion channel". All Ions passing through this channel unidirectional flow too, only out and no in. Compared with K+, they have two states of "open" and "closed", When they are "open", their aperture is not less than K+ diameter. When "closed", their aperture is smaller than K+ diameter, but not smaller than Na+ diameter. This model reasonably explains the whole process of action potential occurrence, and supports Hodgkin, Huxley 's experimental the results of action potential. This model does not support their explanation of the mechanism of action potential generation in cells and the core ideas of "membrane theory" and "ion theory". It negates the selective filter atomic model and the propeller model established by MacKinnon et al. It is tiped that the main role of "sodium-potassium pump" or "ATPase" is not responsible for the transport of Na+ and K+ from the inside and outside of the cell and maintaining cell membrane potential. The channels through which ions enter and escape cells are independent. This suggests that most channels may be sharing in the same direction by other inorganic ions and organic molecules.

This is our commentary on the "What is IQ? Life Beyond "General Intelligence"" paper by Kovacs and Conway (2019- https://doi.org/10.1177/0963721419827275). We advocate for a latent variable approach in experimental research, and illustrate both conceptual and statistical benefits of using this approach in context of research on cognition. Benefits include the availability of more information about the constructs being measured, the ability to check for specific or general effects of covariates, and larger statistical power to detect mean differences between groups.
Different laterality indexes are poorly correlated with one another but consistently show the tendency of males and females to be more left- and right- lateralised, respectively
Authors: Buenaventura Castillo Carlos Emilio , Lynch Andy Graeme , Paracchini Silvia
Published: September 2019

The most common way to assess handedness is based on the preferred hand for writing, leading to a binary (left or right) trait. Handedness can also be assessed as a continuous trait with laterality indexes, but these are not time and cost effective, and are not routinely collected. Rarely, different handedness measures are collected for the same individuals. Here, we assessed the relationship of preferred hand for writing with four laterality indexes, used in previous literature and derived from measures of dexterity (pegboard task, marking squares and sorting matches) and strength (grip strength), available in a range of N = 6664-8069 children from the ALSPAC cohort. Although all indexes identified a higher proportion of individuals performing better with their right hand, they showed low correlation with each other (0.08 - 0.3). Left-handers were less consistent compared to right handers in performing better with their dominant hand, but that varied across indexes, i.e. 13% left handers performed better with their right hand on marking squares compared to 48% for sorting matches and grip strength. Analysis of sex effects on the laterality indexes showed that males and females tend to be, on all measures, more left-and right-lateralised, respectively. Males were also over-represented among the individuals performing equally with both hands suggesting they had a higher tendency to be weakly lateralised. This study shows that different handedness measures tap into different dimensions of laterality and cannot be used interchangeably. The trends observed across indexes for males and females suggest that sex effects should be taken into account in handedness and laterality studies.
Trade, migration, and the dynamics of spatial interaction
Authors: Gauthier Nicolas
Published: September 2019

Archaeological settlement patterns are the physical remains of complex webs of human decision-making and social interaction. Entropy-maximizing spatial interaction models are a means of building parsimonious models that average over much of this small-scale complexity, while maintaining key large-scale structural features. Dynamic social interaction models extend this approach by allowing archaeologists to explore the co-evolution of human settlement systems and the networks of interaction that drive them. Yet, such models are often imprecise, relying on generalized notions of settlement "influence" and "attractiveness" rather than concrete material flows of goods and people. Here, I present a dis-aggregated spatial interaction model that explicitly resolves trade and migration flows and their combined influence on settlement growth and decline. I explore how the balance of costs and benefits of each type of interaction influence long-term settlement patterns. I find trade flows are the strongest determinant of equilibrium settlement structure, and that migration flows play a more transient role in balancing site hierarchies. This model illustrates how the broad toolkit for spatial interaction modeling developed in geography and economics can increase the precision of quantitative theory building in archaeology, and provides a road-map for connecting mechanistic models to the empirical archaeological record.
An Integrated Heuristic for Validation in Sequence Analysis
Authors: Piccarreta Raffaella , Struffolino Emanuela
Published: September 2019

Sequence Analysis is a collection of tools to describe life courses represented as sequences that are increasingly applied in different fields, particularly in demography, sociology, and political sciences. Identifying typologies through cluster analysis, thus disregarding individual sequences’ peculiarities, is the aim of most applications. However, a substantive interpretation of such typology can be questionable when clusters include sequences deviating from the others. We propose an integrated approach to identify such sequences, distinguishing between sequences presenting structural peculiarities and randomly deviating sequences. We monitor the quality of partitions with respect to the amount and type of deviation in each cluster relying on novel graphical tools allowing to properly visualize and closely inspect the structure of deviating sequences. We demonstrate that the identification of deviating sequences provides relevant insights also when clusters are used as dependent or independent variables in an explanatory framework, for example in combination with multinomial logistic regression analysis.

The financial crisis by definition is a situation where several financial assets lose most of their nominal value. The financial crisis experienced by Indonesia in 1997 had a severe impact on the Indonesian economy, so a model was needed to detect this crisis. The financial crisis can be detected using the nominal exchange rate indicator. This study aims to determine the appropriate combination of volatility models and the Markov switching model as a model for detecting financial crises in Indonesia based on nominal exchange rate indicators. The nominal exchange rate indicator taken from 1990 to 2018 is used to build a model for early detection of the financial crisis in Indonesia. The results showed that the combined exponential generalized autoregressive conditional heteroscedasticity and Markov regime switching, MRS-EGARCH (3,1,1) volatility models were both used to detect financial crises in Indonesia based on nominal exchange rate indicators

In the era of regional autonomy the political-economic transformation is still dominated by state and market, while society is in marginal position. Society is often only the object of exploitation of the state and the market. Industrialization developed by the state and the market often forces the middle and small classes to be isolated in their own environment.The potential of natural resources within the middle and small communities is often exploited through access and governance of state and market dominance. When viewed based on the potential that exists, should the governance of the Indonesian economy is based on the industrialization of small and medium-sized society.Experience in the economic crisis of 1998, shows that small and medium industries in the medium and small are relatively able to survive. Compare with large industries that collapsed a lot, unable to survive because the wheels of production driven with machines from debt. The small and medium-sized economy has so far become the main savior of the crisis and the stagnation of economic growth in Indonesia. Efforts to develop local economies through industrialization driven by the urban middle-class society can be an alternative to creating resilience of populist economy, especially in stemming globalization characterized by economic liberalization in various business sectors.This research seeks to analyze some cases, and strategic experience. Especially with regard to Muslim entrepreneurs in the Johar Baru area of Central Jakarta in carrying out various strengthening strategies in local economic development. Entrepreneur Muslim here refers more to the identity of these business actors who are Muslim identity and have a commitment in applying Islamic ethics in running their business and strengthening fellow profession.
A Study on Robustness of Various Deformable Image Registration Algorithms on Image Reconstruction Using 4DCT Thoracic Images
Authors: Parande S , Esmaili Torshabi A
Published: September 2019

Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. This information may be useful for better diagnosis of possible lesions or better tumor delineation at radiation treatment. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images. Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DIR-lab group were utilized. Four implemented registration algorithms as 1) Original Horn-Schunck, 2) Inverse consistent Horn-Schunck, 3) Original Demons and 4) Fast Demons were implemented to represent deformation fields by means of DIRART software packages. Then, the calculated vector fields are processed to reconstruct 4DCT images at any desired time using optical flow based on interpolation method. As a comparative study, the accuracy of interpolated image obtained by each strategy is measured by calculating mean square error between the interpolated image and real middle image as ground truth dataset. Results: Final results represent the ability to accomplish image interpolation among given two-paired images. Among them, Inverse Consistent Horn-Schunck algorithm has the best performance to reconstruct interpolated image with the highest accuracy while Demons method had the worst performance.  Conclusion: A comparative study was conducted to quantitatively investigate the role of four available deformable image registrations for finding interpolated virtual image between two consequent tomography images. Since image interpolation is affected by increasing the distance between two given available images, the performance accuracy of four different registration algorithms is investigated concerning this issue. As a result, Inverse Consistent Horn-Schunck does not essentially have the best performance especially in facing large displacements happened due to distance increment.

Published: September 2019

Background: The aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age.Materials and Methods: Twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algorithm and then instantaneous changes of the twist and torsion were calculated over the cardiac cycle.Results: The rotation amount between the consecutive frames in basal and apical levels was extracted from short axis views by tracking the speckle pattern of images. The maximum basal rotation angle for men and women were -6.94°±1.84 and 9.85°±2.36 degrees (p-value = 0.054), respectively. Apex maximum rotation for men was -8.89°±2.04 and for women was 12.18°±2.33 (p-value < 0.05). The peak of twist angle for men and women was 16.78 ± 1.83 and 20.95± 2.09 degrees (p-value < 0.05), respectively. In men and women groups, the peak of calculated torsion angle was 5.49°±1.04 and 7.12± 1.38 degrees (p-value < 0.05), respectively.Conclusions: The conclusion is that although torsion is an efficient parameter for left ventricle function assessment, because it can take in account the heart diameter and length, statistic evaluation of the results shows that among men and women lv mechanical parameters are significantly different. This study was mainly ascribed to the dependency of the torsion and twist on patient sex.

Bài báo sử dụng phương pháp mô phỏng phần tử hữu hạn (PTHH) để nghiên cứu khả năng chịu uốn của cấu kiện ống tròn hai lớp thép nhồi bê tông (Concrete-Filled Double skin Steel Tubes-CFDST) có mối nối ở giữa dùng để liên kết các cấu kiện có kích thước lớn ngoài khả năng vận chuyển. Mô hình mô phỏng PTHH của thí nghiệm uốn 4 điểm trên cấu kiện CFDST có mối nối được xây dựng bằng phần mềm ABAQUS và được chứng minh là đúng bằng cách so sánh với thí nghiệm. Mô hình PTHH được dùng để đánh giá khả năng chịu uốn của cấu kiện CFDST có liên kết mối nối dưới sự thay đổi của cường độ thép ống cũng như cường độ chịu nén của bê tông nhồi trong ống. Từ đó, mối liên hệ giữa khả năng chịu uốn của cấu kiện với sự thay đổi cường độ thép ống cũng như cường độ chịu nén của bê tông nhồi được đề xuất.

El liposarcoma es un tumor mesenquimático maligno, originado en el tejido adiposo, y constituye la variedad más frecuente de los sarcomas de ubicación retroperitoneal. Tienen un crecimiento lento con síntomas tardíos fundamentalmente dados por compresión, dado que pueden alcanzar un gran tamaño. El tratamiento es la resección quirúrgica completa, y el pronóstico depende de la estadificación final, el grado tumoral y una cirugía radical.

Presentamos a continuación un caso de un liposarcoma retroperitoneal gigante de diagnóstico y resolución en nuestro servicio.
On the finiteness of the number of elliptic fields with given degrees of S-units and periodic expansion of √f
Authors: Platonov V. P. , Petrunin M. M. , Shteinikov Yu. N.
Published: September 2019

For a field k of characteristic 0, up to a natural equivalence relation, it is proved that the number of nontrivial elliptic fields k(x)(f) with a periodic expansion of f ∈ k((x)), for which the corresponding elliptic curve contains a k-point of even order less or equal than 18 or k-point of odd order less or equal than 11, is finite. In case k is a quadratic extension of Q, all such fields are found.
Taking into account the fluid saturation of bottom sediments in marine seismic survey problem
Authors: Golubev V. I. , Shevchenko A. V. , Petrov I. B.
Published: September 2019

The problem of the numerical simulation of the seismic response from the marine bottom is considered. Acoustic equations are used for the description of the water dynamic behavior. Bottom sediments are described with the porous fluid-filled medium. The Dorovsky model is used. The algorithm for solving all hyperbolic equation systems with the grid-characteristic method was proposed. The distinctive feature of this approach is the ability to set explicitly necessary contact conditions between media with different rheology.

For the first time, numerical radioisotope age were obtained for the “cross-laminated sandy” stratum, which is widespread in Neopeopleistocene reference sections of loose sediments from Central Kamchatka. Two peat layers, incorporated in the “cross-laminated sandy” stratum of the Yar Sredny, were studied. The results of their paired 230Th/238U and 14C dating are in good agreement with each other. According to the dating results, it was determined that the “cross-laminated sandy” stratum was deposited, apparently, in the range of about 50-40 thousand years ago, i.e. in the Late Pleistocene (MIS-3), and not in the Middle Pleistocene, about 400-300 thousand years ago, as previously thought.

40Ar/39Ar-dating of the micas from the schists and blastomylonites collected from the fault which separates the Eastern zone of the Middle Urals dipped under the cover of the West Siberian plate from the open part of the geologic structures of the Urals, showed that the last phase of deformation was represented by a submeridional sinistral strike-slip faults with the age of 251 Ma. The appearance of the analyzed deformations practically exactly coincides in time with the formation of the grabens of meridional strike at the base of the West Siberian plate.

This paper presents age data of the Elabuga zone rocks metamorphism and of the detrital zircon of the Elabuga zone paragneisses and their correlation with the age of Middle-Volga megablock rocks. The Elabuga zone rocks and the Middle-Volga megablock rocks have similar geochemical characteristics and degree of metamorphism. Difference is as follows: Paleoproterozoic metamorphism is occurred at the studied Elabuga zone rocks and such metamorphism age is not presented at the Middle-Volga megablock rocks. The study of U-Pb isotopic system in external zones in the Elabuga deformation zone zircon crystals suggests that rocks were underwent by metamorphism of two stages 1.99 and 1.95 Ga ago.

Selective anxiolytic fabomotisol (Afobazol®) has affinity for the Sigma-1 chaperone receptor site, quinone reductase 2 (NQO2) and MAO-A regulatory sites, and melatonin receptor type 1 (MT1 receptor). The analysis of the effect of fabomotisol on the gene expression profile in the brain of MR (Maudsley Reactive) rats was carried out when modeling emotional stress in the open field test. A change in the expression of 14 genes was found, the results of the functional annotation of which show that the mechanisms of action of fabomotisol may be associated with the regulation of translation of proteins (Rpl5, Rpl15, Ncl, Ybx1), synaptic functions (Cplx2, Dlg4, Syngap1, Add1, Rab8b, Klc1, Chn1) and cellular metabolism (Akr1d1, Bcat1, Pkm).

Authors: Litvinov I. S. , Dolgikh D. A.
Published: September 2019

Prolonged contact of healthy subjects with Mycobacterium tuberculosis can change their blood formula and immune status, thus reflecting adaptive reactions to constant antigenic load. The peripheral blood analysis of health care workers (HCWs) in a tuberculosis hospital demonstrates changes in cell populations which prevent development of tuberculosis, in particular, CD4+ Т cells and CD3+ Т cells. It is shown that the number of the memory CD4+ Т cells specific to M.tuberculosis antigens which produce interferon gamma depends on the duration of work contact with tuberculosis patients. The HCWs blood characteristics usage as a control for tuberculosis patients is discussed.
