Immunopathological mechanisms involved in SARS-CoV-2 infection

ABSTRACT Introduction: Coronavirus disease 2019 (Covid-19) has become a global health emergency. Although many scientific advances have been achieved over the last few months, the knowledge about how the etiologic agent SARS-CoV-2 interacts with the host's immune system, regulating the pathogenesis and the outcome of the disease, is not yet fully understood. Objective: This is a narrative literature review to discuss the available evidence on modes of transmission and the main immunopathological mechanisms involved in SARS-CoV-2 infection. Material and method: A search in the indexed journals was carried out in the PubMed/MEDLINE database, during the period from January to May 2020. The following descriptors were used in the research: Covid-19, SARS-CoV-2, transmission, immunity, immunopathogenesis, and pathogenesis. Results and discussion: Transmission of SARS-CoV-2 occurs through contact with airway secretions from a symptomatic patient. However, scientific evidence encourages transmission by asymptomatic and/or oligosymptomatic patients. Immunopathological studies suggest that the hypercytokinaemia promotes lung tissue damage and, subsequently, organ and system involvement, leading to decompensation, organ dysfunction and death. Regarding the humoral response, the high titers of B lymphocytes and antibodies, traditionally, correlated with the protection of the host, may be associated with the severity of the disease by SARS-CoV-2. Conclusion: The host's immune response is determinant in the pathogenesis of Covid-19. However, further in vivo and/or in vitro studies are needed to elucidate the pathogenic mechanisms of SARS-CoV-2 and, thus, assist in the development of a vaccine and/or therapeutic target.
Thermally Induced Grafting Reactions of Ethylene Glycol and Glycerol Intercalates of Kaolinite

Inorganic-organic layered hybrid materials based on kaolinite were prepared from dehydrated potassium acetate intercalated through the guest-displacement reaction with ethylene glycol and glycerol. These materials were characterized and their behavior upon heating was investigated using X-ray diffraction, diffuse reflectance Fourier transform infrared spectroscopy, and combined thermogravimetry and differential scanning calorimetry coupled with mass spectroscopy. An intense perturbation of the AlAlOH stretching vibrations of kaolinite in the range 3700−3600 cm-1 was observed for both of the intercalates, indicating strong interactions with the kaolinite surface OH groups. The two intercalates showed different thermal behavior. The ethylene glycol intercalates decomposed in a nitrogen atmosphere at 160 °C, with the release of the ethylene glycol from adjacent kaolinite layers. The glycerol intercalate showed a three-step decomposition over the temperature range 115−465 °C associated with dehydroxylation re.
HOW HR PRACTICES AFFECT ORGANIZATIONAL COMMITMENT AND ORGANIZATIONAL CITIZENSHIP BEHAVIOR

The HRM and effective HR practices play an important role for promoting a committed environment and a culture of citizenship. This study is intended to explore the HRM systems’ dynamics and applied HR practices in Lebanese banks and to find their possible link with employee commitment and citizenship behavior. The primary research selected six most representative Lebanese banks. A questionnaire on employee commitment and citizenship behavior was sent to each bank’s HR officers. The questions were derived from the OCQ, ACS, CCS, NCS, and CBS. Direct positive relationship between HR and organizational commitment was not completely verified in terms of the Lebanese bank institutions. The HR-OCB relationship is much more coherent and noticeable especially when the HR role of employee champion emerges. Commitment has a strong relationship with the OCB. Lebanese banks have very promising examples of serious dynamic HRM initiatives that promote employees’ support and recognize their efforts while trying to capitalize on their competences, commitment, and displayed citizenship behaviors.
Characterization of Phosphorus in a Spruce-Fir Spodosol by Phosphorus-31 Nuclear Magnetic Resonance Spectroscopy

Factors affecting the distribution and biogeochemical cycling of soil P are only partially understood. Many previous studies have focused on P distribution within surface mineral soils and cyclyng of inorganic P. Few data are available on organic forms of P in forest floor and mineram horizonss of forest soils. Therefore, we used 31 P nuclear magnetic resonance ( 31 P-NMR) to characterize the P compounds in NaOH-ethylenediaminetetraacetic acid (EDTA) extracts of three Spodosol profiles. The NaOH-EDTA extracted most of the P in the three organic horizons (87, 83, and 69% of total P in Oi, Oe, and Oa horizons, respectively) and 39 to 67% in the Bhs horizon. Major P species detected in all horizons were inorganic orthophosphate and orthophosphate monoesters and diesters that ranged from 11 to 53%, 12 to 52%, and 13 to 45% of total P extracted, respectively. As is typical in Spodosol chemistry, considerable variation was found for organic P distribution in the organic horizons of the three profiles. However, on average, distribution patterns of P forms with depth were observed, including a decrease in the proportion of inorganic orthophosphate with greater decomposition in the forest floor (Oi > Oe > Oa), followed by an increase in the Bhs horizons. Pyrophosphate (5-19% of total P) and polyphosphates (5-13% of total P) were found mainly in the forest floor horizons, except for one profile where pyrophosphate had evidently accumulated in the Bhs horizon. Traces (2%) of phosphonates occurred only in the Oa horizon. Results suggest that biological activity, extractable Fe concentration, structural characteristics of P compounds, and pH are probably responsible for the distribution of P species in these Spodosols.
Disentangling the taxonomy of the Galactia-Camptosema- Collaea complex with new generic circumscriptions in the Galactia clade (Leguminosae, Diocleae)

The Galactia clade is one of three major lineages of the papilionoid legume tribe Diocleae. It comprises eight genera and approximately 140 species almost entirely restricted to the Americas. Establishing stable generic boundaries within this clade has been a challenge because of its tortuous taxonomic history and the broad polyphyly of the genera of the so-called Galactia-Camptosema-Collaea complex. Previous molecular phylogenetic studies revealed some well-supported lineages, but did not advance towards any new taxonomic arrangements. We carried out maximum parsimony and Bayesian phylogenetic analyses of a combined dataset including our previously published multilocus molecular data (nrITS and ETS and plastid trnK/matK and trnT-Y regions) and 82 morphological characters. The resulting topologies largely concur with those previously reported based on molecular data only, where Camptosema and Galactia appear as broadly polyphyletic, with species scattered among five (Camptosema) and seven (Galactia) of the twelve lineages that are newly recognized here at genus level. We are therefore proposing the following new taxonomic rearrangements within the Galactia clade: descriptions of the new genera Caetangil, Cerradicola, Mantiqueira, and Nanogalactia; resurrection of Betencourtia; and the subsuming of Neorudolphia into Rhodopis and of Camptosema sect. Macropetalum into Cratylia.
Quality of Accounting Information Systems and Their Impact on Improving the Non-Financial Performance of Jordanian Islamic Banks

Current study aimed at examining the influence of quality of AIS outputs in improving non-financial performance of Jordanian Islamic banks, AIS outputs characteristics included (Relevance, Credibility, Procedures and instructions, Timelines, IT infrastructure and Feedback Value). In order to achieve aim, researcher adopted a quantitative approach utilizing a questionnaire. After application; (150) individuals within financial departments in Jordanian Islamic banks responded o he questionnaire; and analysis showed that the quality of AIS outputs plays a role in improving and defining non-financial performance. The influence mainly was attributed to credibility which appeared to be the most influential among all, followed by relevance and procedures and instruction in the 2nd and 3rd ranks respectively. Study recommended the necessity for Jordanian Islamic banks to prepare a strategic plan and implement it to develop electronic accounting information systems to achieve the continuity of the quality of that information and the principles of systems reliability in an integrated manner.
Rationalization of the Synthesis of SBA-16: Controlling the Micro- and Mesoporosity

The effects of the synthesis parameters on the properties of the cubic Im3m SBA-16 have been investigated systematically for the first time. We show that the total pore volume, pore diameter, and ratio micro-/mesopores can be controlled very efficiently by changing the synthesis time, temperature, and the TEOS/surfactant ratio. We also argue that at high TEOS/surfactant ratios, structures with internal microporous nanocapsules will be created. These materials have unprecedentedly high micropore contributions, which can comprise up to 65% of the total pore volume.
Arsenic Uptake by Rice and Accumulation in Soil Amended with Municipal Solid Waste Compost

Effect of municipal solid waste compost (MSWC) on arsenic content of submerged rice paddies was studied. Experiments were conducted during the three consecutive wet seasons from 1997 to 1999 on rice grown under submergence, at the Experimental Farm of Calcutta University, India. A sequential extraction method was used to determine the various arsenic fractions in MSWC and cow dung manure (CDM). Arsenic (As) was significantly bound to the organic matter and iron (Fe) and manganese (Mn) oxides in MSWC and CDM. Arsenic content in rice straw was higher than rice grain. Arsenic bound with Fe and Mn oxides best correlated with straw As (r = + 0.99**) and grain As (r = + 0.99**) content. The As bound with organic matter followed next (r = + 0.98** for straw, and r = + 0.94* for grain) with the exchangeable part being also significant with straw (r = + 0.94*). In CDM, the As content of rice grain correlated best with water soluble As (r = + 0.96**) while the straw As content was best correlated with exchangeable As (r = + 0.99**) followed by As bound with organic matter (r = + 0.98**). MSWC effectively served as binding agent for native soil arsenic thereby moderating the rapid arsenic mobilization to the crop rhizosphere.
Relationship between internet addiction and mental health in adolescents

BACKGROUND: Internet addiction (IA) currently is the major public health concern, especially in adolescents, although the results of previous reports are not generally uniform. This study was conducted to determine IA in adolescents and to examine the correlation of IA with mental health in adolescents. METHODS: This cross-sectional study was conducted in 2019 in Ilam city. In this study, 362 persons were included using stratified cluster sampling; clusters were geographical area and schools. The valid questionnaires including Internet Addiction Test and 28-item General Health Questionnaire (GHQ-28) were used to interview. The correlation statistical technique was used to determine the association between the two variables. The significance level was considered <0.05. RESULTS: The mean ± standard deviation age of the responders was 16.40 ± 2.47 years; the total score of IA and mental health was 43.02 ± 16.50 and 19.27 ± 9.72, respectively. We found that 5.5% of the adolescents had a severe level of IA. The lack of control with anxiety, neglect work and social dysfunction, and neglect social life and severe depression in internet users were found to be statistically significant: r (365) = 0.151, P < 0.033; r (365) = 0.126, P < 0.021; and r (365) = 0.125, P < 0.033, two-tailed, respectively. CONCLUSION: According to the results, the excessive use of internet, lack of control, and neglect social life are significantly correlated with mental health in adolescents; these results could be contribute to improve the theoretical models for IA in adolescents.
Influence of CO2, SO2 and NO in flue gas on microalgae productivity

The influence of CO2, SOx, NOx and soot dust on the productivity of microalgae was considered using Nannochloropsis salina and Phaeodactylun tricornutum. Microalgae are viewed as a possible means of combeting global warming.These microalgae can be easily cultivated in a high CO2 gas concentration of 15 vol%. SO2 gas itself does not influence the growth of microalgae. However, when the SO2 concentration is high, the pH of the medium decreases and the productivity of the microalgae is lowered.The presence of NO does not influence the growth of microalgae. NO absorbed in the medium is changed to NO2– and utilized as a nitrogen source.As for Ni and V contained in soot dust, when the dissolved concentrations of these metals in the medium exceed more than 1 and 0.1 ppm, respectively, the microalgae productivity decreases, however, under actual conditions, their concentrations are normally lower than these values.The above results obtained in a small scale test using a simulated gas were confirmed in a field test using a raceway-type reactor with actual flue gas.
Time-of-flight secondary-ion-mass spectrometric (ToF-SIMS) and X-ray photoelectron spectroscopic (XPS) analyses of the surface lipids of wool

ToF-SIMS studies of wool show the presence of lipid material at the surface epicuticle layer. The major lipid component is a C21-fatty acid linked to the wool protein via a thioester linkage. This C21-fatty-acid species is sensitive to chemical attack and is removed/modified by aqueous chlorination and plasma treatment but is relatively unaffected by permonosulphuric acid (PMS)/sulphite treatment. XPS confirms that less sulphur oxidation occurs with PMS/sulphite treatment than with aqueous chlorination.
Sulphur and Oxygen Isotopes in Sulphates in Natural Waters: (1) Surface Waters of Relatively Unpolluted Terrains

Abstract The paper presents a whole-year study (1990) of an unique area in S-E Poland with numerous small rivers and streams carrying clean waters. We report the results of δ18O of waters and δ34S of the sulphates sampled 4 times in 1990 from 20 rivers of the study area. The observations clearly show the impact of biological activity on the oxygen and sulphur isotopic compositions in sulphates. Attempts have been made to interpret the correlation between δ34S and δ18O in sulphates. The highest correlation coefficient has been noticed for samples collected in April, whereas the lowest in August. The conclusion of this study is that the river sulphates are predominantly produced outside the river environment. We have distinguished three major sources of sulphates: (1) ones produced in the aquifer from which waters are discharged, (2) those produced in soils and marshes of forest environment, and (3) ones on anthropogenic origin.
Raman spectroscopic study on the structural changes of polyaniline during heating and cooling processes

Polyaniline (PANI) in three ground states—emeraldine base (EB), leucoemeraldine base (LEB), and pernigraniline base (PNB)—were studied by Raman spectroscopy in the temperature scale of −195 to about 375°C. The Raman spectral results demonstrated that a crosslinking reaction occurred on EB chains at high temperatures, whereas the phenyl torsion angles of EB chains decreased during the cooling process. LEB was unstable and was gradually converted to EB during the heating process, although its chain conformation remained stable by cooling. The spectral change tendency of PNB was similar to that of EB during the heating process. Although the torsion angle of PNB also decreased with decreasing temperature, like that of EB, this behavior was hard to observe experimentally because of the relatively “free ” rotation of its phenyl rings. © 2005 Wiley Periodicals, Inc.

Mate extract on lipid and color changes of dourado fillets during frozen storage

This study aimed to evaluate whether mate (Ilex paraguariensis A. St. Hil) extract would change lipid and color stability of dourado (Salminus brasiliensis) fillets during frozen storage. Fish fillets were dipped (1 min) in distilled water (control) or in aqueous extract of mate (0.1g mL-1, w/v) and were stored at -7°C for up to 12 months. Conjugated dienes (CD) increased in control fillets after 6 months of storage and then decreased, whereas thiobarbituric acid reactive substances (TBARS) value increased along the whole experimental period. Mate treatment reduced CD and TBARS values of fillets. Dourado fillets tended to yellow along the whole experimental period (average H*= 72.55) Although the mate treatment had increased the yellowness of fillets at the start of storage, this treatment reduced the increase in luminosity (L*) and in yellowness (H*) triggered by frozen storage. Results indicate that mate extract inhibits lipid oxidation and some color changes caused by the frozen storage of fish fillets.
Scale-free Protocol Design for Output and Regulated Output Synchronization of Heterogeneous Multi-agent Systems

In this paper, we consider scalable output and regulated output synchronization problems for heterogeneous networks of right-invertible linear agents based on localized information exchange where in the case of regulated output synchronization, the reference trajectory is generated by a so-called exosystem. We assume that all the agents are introspective, meaning that they have access to their own local measurements. We propose a scale-free linear protocol for each agent to achieve output and regulated output synchronizations. These protocols are designed solely based on agent models and they need no information about communication graph and the number of agents or other agent models information.
Segment Distribution around the Center of Gravity of a Triangular Polymer

The segment distribution around the center of gravity is investigated for a special comb polymer (triangular polymer) having the side chains of the same generation number, $g$, as the main backbone. Common to all the other polymers, the radial mass distribution is expressed as the sum of the distribution functions for the end-to-end vectors, $\{\vec{r}_{Gh}\}$, from the center of gravity to the monomers on the $h$th generation; the result being, for a large $g$, \begin{equation} \varphi_{\text{triang}}(s)=\frac{1}{N}\left\{\sum_{h=1}^{g}\left(\frac{d}{2\pi\left\langle r_{Gh}^{2}\right\rangle}\right)^{\frac{d}{2}}\text{Exp}\left(-\frac{d}{2\left\langle r_{Gh}^{2}\right\rangle}s^2\right)+\sum_{h=2}^{g}\sum_{j=1}^{g-h}\left(\frac{d}{2\pi\left\langle r_{Gh_{j}}^{2}\right\rangle}\right)^{\frac{d}{2}}\text{Exp}\left(-\frac{d}{2\left\langle r_{Gh_{j}}^{2}\right\rangle}s^2\right)\right\}\notag \end{equation} It is found that the mean square of the radius of gyration varies as $\left\langle s_{N}^{2}\right\rangle_{0}\doteq\frac{7}{15}\,g\,l^{2}$, as $g\rightarrow\infty$. Since $g\propto \sqrt{N}$ for the triangular polymer, this leads to $\left\langle s_{N}^{2}\right\rangle_{0}^{1/2}\propto N^{1/4}$, giving the same exponent as observed for the randomly branched polymer. On the basis of the present result, we put forth that all the known polymers obey the equality: $\left\langle s_{N}^{2}\right\rangle_{0}=A\, g\,l^{2}$, where $A$ is a polymer-species-dependent coefficient and also depends on the choice of the root monomer. We discuss the extension of this empirical equation.
CP
-violating Higgs boson ditau decays: Baryogenesis and Higgs factories

We demonstrate how probes of CP-violating observables in Higgs di-tau decays at prospective future lepton colliders could provide a test of weak scale baryogenesis with significant discovery potential. Measurements at the Circular Electron Positron Collider, for example, could exclude a CP phase larger than $2.9^\circ$ ($5.6^\circ$) at 68% (95%) C.L. assuming the Standard Model value for magnitude of the tau lepton Yukawa coupling. Conversely, this sensitivity would allow for a $5\,\sigma$ discovery for 82% of the CP phase range $[0,2\pi)$. The reaches of the Future Circular Collider - ee and International Linear Collider are comparable. As a consequence, future lepton colliders could establish the presence of CP violation required by lepton flavored electroweak baryogenesis with at least $3\,\sigma$ sensitivity. Our results illustrate that Higgs factories are not just precision machines but can also make $\mathcal O(1)$ measurement of the new physics beyond the Standard Model.
Blowup dynamics for smooth equivariant solutions to energy critical Landau-Lifschitz flow

In this paper, we study the energy critical 1-equivariant Landau-Lifschitz flow mapping $\mathbb{R}^2$ to $\mathbb{S}^2$ with arbitrary given coefficients $\rho_1\in \mathbb{R}$, $\rho_2>0$. We prove that there exists a codimension one smooth well-localized set of initial data arbitrarily close to the ground state which generates type-II finite-time blowup solutions, and give a precise description of the corresponding singularity formation. In our proof, both the Schr\"odinger part and the heat part play important roles in the construction of approximate solutions and the mixed energy/Morawetz functional. However, the blowup rate is independent of the coefficients.
Fine-grained Emotion and Intent Learning in Movie Dialogues

We propose a novel large-scale emotional dialogue dataset, consisting of 1M dialogues retrieved from the OpenSubtitles corpus and annotated with 32 emotions and 9 empathetic response intents using a BERT-based fine-grained dialogue emotion classifier. This work explains the complex pipeline used to preprocess movie subtitles and select good movie dialogues to annotate. We also describe the semi-supervised learning process followed to train a fine-grained emotion classifier to annotate these dialogues. Despite the large set of labels, our dialogue emotion classifier achieved an accuracy of $65\%$ and was used to annotate 1M emotional movie dialogues from OpenSubtitles. This scale of emotional dialogue classification has never been attempted before, both in terms of dataset size and fine-grained emotion and intent categories. Visualization techniques used to analyze the quality of the resultant dataset suggest that it conforms to the patterns of human social interaction.
Vacuum stability conditions for Higgs potentials with 
SU(2)L
 triplets

Tree-level dynamical stability of scalar field potentials in renormalizable theories can in principle be expressed in terms of positivity conditions on quartic polynomial structures. However, these conditions cannot always be cast in a fully analytical resolved form, involving only the couplings and being valid for all field directions. In this paper we consider such forms in three physically motivated models involving $SU(2)$ triplet scalar fields: the Type-II seesaw model, the Georgi-Machacek model, and a generalized two-triplet model. A detailed analysis of the latter model allows to establish the full set of necessary and sufficient boundedness from below conditions. These can serve as a guide, together with unitarity and vacuum structure constraints, for consistent phenomenological (tree-level) studies. They also provide a seed for improved loop-level conditions, and encompass in particular the leading ones for the more specific Georgi-Machacek case. Incidentally, we present complete proofs of various properties and also derive general positivity conditions on quartic polynomials that are equivalent but much simpler than the ones used in the literature.
