Repeated leftover serosurvey of SARS-CoV-2 IgG antibodies, Greece, March and April 2020

A serosurvey of IgG antibodies against severe acute respiratory coronavirus 2 (SARS-CoV-2) was performed during March and April 2020. Among 6,586 leftover sera, 24 (0.36%) were positive, with higher prevalence in females, older individuals and residents of large urban areas. Seroprevalence was estimated at 0.02% and 0.25%, respectively, in March and April, infection fatality rate at 2.66% and 0.54%. Our findings confirm low COVID-19 incidence in Greece and possibly the effectiveness of early measures.
Physiological Responses of Corticosteroid , Dexamethasone in Broiler Chicken

The synthetic corticosteroids, dexamethasone (DEX) are widely used in veterinary medicine. Their illicit use as a growth promoter in fattening is well known in animal. The illegal uses of the growth promoters and its residues present in food producing animals may have potential risk for the human health. The present study is aimed to observe the effects of DEX in blood profile of broiler chicken. Ninety ‘COBB 500’ broilers were divided into control, experimental group A and B. The control, group A and B were maintained with homemade ration, commercial broiler type ration and homemade ration with DEX (7mg/kg feed) respectively in their diets. The percentage of hemoglobin concentration, packed cell volume (PCV), differential leukocyte count (DLC), total erythrocyte count (TEC), productive performance (body weight, dress body weight, feed intake) were investigated at days 7, 14, 21, 28 in broilers. The weight gain and dressed weight of broilers receiving DEX in their diets was significantly lower than that of the control and group 1 on day 14, 21 and 28 (p<0.05). The percentage of TEC, PCV, HB, DLC (neutrophil) is significantly increased at day 28 in group 2 as compared to control and group 1 (p<0.05). Significantly decrease amount of lymphocytes are found in DEX treated group at day 28 (p<0.05). The percentage of monocyte and basophil were remaining normal in all groups of chicken. The present results indicate that DEX had effects in the physiology of broiler chicken.

Submanifolds of Euclidean space with parallel second fundamental form.

In this paper necessary conditions are given for a complete Riemannian manifold Mn to admit an isometric immersion into Rn+P with parallel second fundamental form. Namely, it is shown that Mn must be affinely equivalent either to a totally geodesic submanifold of the Grassmann manifold G(n, p), or to a fibre bundle over such a submanifold, with Euclidean space as fibre and the structure being close to a product. (An affine equivalence is a diffeomorphism that preserves Riemannian connections.) The proof depends on the auxiliary result that the second fundamental form is parallel iff the Gauss map is a totally geodesic map.
Potential Impact of Spacing and Fertilizer Levels on the Flowering, Productivity and Economic Viability of Hybrid Bhendi ( Abelmoschus esculentus L. Moench) under Drip Fertigation System

Drip irrigation provides an efficient method of fertilizer delivery and allows precise timing and uniform distribution of applied nutrients. Fertilizer application through drip irrigation (fertigation) can reduce fertilizer usage and minimize groundwater pollution due to fertilizer leaching from excessive irrigation. For this purpose, field experiments were carried out in the farmers’ field at Thoppur, Dharmapuri District, Tamil Nadu, during 2010-2012 to study the effect of spacing and fertilizer levels on the flowering, pod yield and economic viability of Bhendi Hybrid (Abelmoschus esculentus L. Moench) under drip fertigation system. The treatments consisted of two spacings (M1—60 × 45 cm and M2— 60 × 30 cm) and eight drip fertigation levels (S1—Drip fertigation with WSF at 125 per cent RDF + Azophosmet + Humic acid, S2—Drip fertigation with WSF at 100 per cent RDF + Azophosmet + Humic acid, S3—Drip fertigation with WSF at 75 per cent RDF + Azophosmet + Humic acid, S4—Drip fertigation with WSF at 100 per cent RDF, S5—Drip fertigation with SF at 125 per cent RDF + Azophosmet + Humic acid, S6—Drip fertigation with SF at 100 per cent RDF + Azophosmet + Humic acid, S7—Drip fertigation with SF at 75 per cent RDF + Azophosmet + Humic acid, S8—Drip fertigation with SF at 100 per cent RDF), and were replicated thrice in a split plot design. Results showed that the earliest flowering (26.21 days), 50% flowering (51.31), number of flowers per plant (25.33) and highest pod yield of 596.70 g/plant, 24.91 t/ha was registered in drip fertigation at 100 per cent recommended dose of fertilizers as water soluble fertilizer combination with Azophosmet and humic acid under wider spacing. The economics of the study clearly showed that drip fertigation at 100 per cent recommended dose of fertilizers as water soluble fertilizer along with Azophosmet and humic acid under wider spacing was found to record higher BCR of 2.99.
Mechanisms underlying genome instability mediated by formation of foldback inversions in Saccharomyces cerevisiae

Foldback inversions, also called inverted duplications, have been observed in human genetic diseases and cancers. Here, we used a Saccharomyces cerevisiae genetic system that generates gross chromosomal rearrangements (GCRs) mediated by foldback inversions combined with whole-genome sequencing to study their formation. Foldback inversions were mediated by formation of single-stranded DNA hairpins. Two types of hairpins were identified: small-loop hairpins that were suppressed by MRE11, SAE2, SLX1, and YKU80 and large-loop hairpins that were suppressed by YEN1, TEL1, SWR1, and MRC1. Analysis of CRISPR/Cas9-induced double strand breaks (DSBs) revealed that long-stem hairpin-forming sequences could form foldback inversions when proximal or distal to the DSB, whereas short-stem hairpin-forming sequences formed foldback inversions when proximal to the DSB. Finally, we found that foldback inversion GCRs were stabilized by secondary rearrangements, mostly mediated by different homologous recombination mechanisms including single-strand annealing; however, POL32-dependent break-induced replication did not appear to be involved forming secondary rearrangements.
Diabetes and COVID-19 risk: an miRNA perspective

Coronavirus disease 2019 (COVID-19) and diabetes outcomes (CORONADO) trial revealed that 10.6% of patients with diabetes mellitus hospitalized for COVID-19 (COVID-19) die within 7 days. Several studies from New York, Italy, and China confirm that patients with diabetes are at a much higher risk for mortality due to COVID-19. Besides respiratory illness, COVID-19 increases cardiac injury and diabetic ketoacidosis. In the absence of specific guidelines for the prevention and treatment of COVID-19 for patients with diabetes, they remain at higher risk and are more susceptible to COVID-19. Furthermore, there is a scarcity of basic knowledge on how diabetes affects pathogenesis of severe acute respiratory coronavirus (SARS-CoV-2) infection. In patients with diabetes, impaired glucose use alters metabolic and consequently biological processes instigating pathological remodeling, which has detrimental effects on cardiovascular systems. A majority of biological processes are regulated by noncoding microRNAs (miRNAs), which have emerged as a promising therapeutic candidate for several diseases. In consideration of the higher risk of mortality in patients with diabetes and COVID-19, novel diagnostic test and treatment strategy are urgently warranted in post-COVID-19 era. Here, we describe potential roles of miRNA as a biomarker and therapeutic candidate, especially for heart failure, in patients with diabetes and COVID-19.
Cold Forming of Al-TiB2 Composites Fabricated by SPS: A Computational Experimental Study

The mechanical response and failure of Al-TiB2 composites fabricated by Spark Plasma Sintering (SPS) were investigated. The effective flow stress at room temperature for different TiB2 particle volume fractions between 0% and 15% was determined using compression experiments on cylindrical specimens in conjunction with an iterative computational methodology. A different set of experiments on tapered specimens was used to validate the effective flow curves by comparing experimental force–displacement curves and deformation patterns to the ones obtained from the computations. Using a continuum damage mechanics approach, the experiments were also used to construct effective failure curves for each material composition. It was demonstrated that the fracture modes observed in the different experiments could be reproduced in the computations. The results show that increasing the TiB2 particle volume fraction to 10% results in an increase in material effective yield stress and a decrease in hardening. For a particle volume fraction of 15%, the effective yield stress decreases with no significant influence on the hardening slope. The ductility (workability) of the composite decreases with increasing particle volume fraction.
The Impact of Instructional Method on the Application of Kinesio Taping® Techniques for Occupational Therapy Students

This research utilized a crossover study design to analyze the differences in learner satisfaction, confidence, and accuracy when comparing in-person, video, and written instructional methods. The study was conducted on a group of 32 occupational therapy students from a local university by teaching them two different Kinesio Taping® protocols. Satisfaction and confidence were measured by survey. The participants completed tapings, then were rated by an instructor to obtain accuracy data. The study found that learning satisfaction was rated higher following video instruction. Regarding confidence, there was a statistically significant difference in the level of confidence for students viewing video instruction for one of two taping techniques presented. No significant difference was found between groups in accuracy in taping after different instructional methods. The use of multiple instructional methods was reported as the most beneficial and preferred method in the study. This study highlights the potential benefits of utilizing multiple instructional methods to aid in student learning.

Ferritinophagy is not required for colon cancer cell growth

Ferritinophagy is a form of selective autophagy responsible for degrading intracellular ferritin, mediated by nuclear receptor coactivator 4 (NCOA4). NCOA4 plays significant roles in systemic iron homeostasis, and its disruption leads to simultaneous anemia and susceptibility to iron overload. The importance of iron colorectal cancer pathogenesis is well studied; however, the role of ferritinophagy in colon cancer cell growth has not been assessed. Disruption of ferritinophagy via NCOA4 knockout leads to only marginal differences in growth under basal and iron‐restricted conditions. Moreover, NCOA4 played no significant role in cell death induced by 5‐fluorouracil and erastin. Western blotting analysis for ferritin and transferrin receptor 1 found a dose‐dependent effect on expression in both proteins in wild‐type and NCOA4 knockout cell lines, but further investigation revealed no difference in growth response when treated at both high and low doses. Our data demonstrate a marginal role for ferritinophagy in growth both under normal and cytotoxic conditions in colon cancer cells, as well as a possible compensatory mechanism in colon cancer cells in response to ferroptosis induction.
Proximal hyper-intense vessel sign on initial FLAIR MRI in hyper-acute middle cerebral artery ischemic stroke: a retrospective observational study

Background A hyper-intense vessel sign on fluid attenuated inversion recovery magnetic resonance imaging (FHV) represents slow blood flow in the cerebral arteries. Purpose To investigate the relationship between the proximal FHV (pFHV) on initial magnetic resonance imaging (MRI) and the status of the culprit vessel (stenosis, obstruction) in hyper-acute strokes affecting the territory of the middle cerebral artery (MCA). Material and Methods The study participants consisted of 105 patients presenting to the emergency department (ED) with acute MCA infarction within 4.5 h of onset of symptoms. Patients underwent brain MRI within 45 min of arrival at the ED and angiography within 2 h of arrival. Culprit vessel status and presence of a pFHV on initial MRI were investigated retrospectively. Results The pFHV was observed in 71/105 (67.6%) patients who presented with a hyper-acute MCA infarction. All patients with hyper-acute MCA infarction caused by internal carotid artery (90.6% caused by M1 occlusion, 92.9% caused by M2 occlusion) showed a pFHV on initial MRI. After logistic regression analysis, the presence of a pFHV showed significant positive correlation with large vessel occlusion (adjusted odds ratio [OR] 34.533, 95% confidence interval [CI] 9.781–121.926; P < 0.001). A pFHV was not associated with severe large vessel stenosis. Conclusion A pFHV is independently representative of the acute occlusion of intervention-eligible proximal arteries within the territory of the MCA. If a patient with a hyper-acute MCA infarction shows a pFHV, aggressive flow augmentation strategies and early activation of intervention team should be warranted for best patient outcome.
Contextual bias and inferencing in adults with right hemisphere brain damage

There is conflicting evidence regarding whether and how well adults with right brain damage (RHD) use contextual cues during comprehension. The current study used a reading time task to assess predictive inference generation in stories with varying contextual bias. Adults with RHD exhibited evidence of inferencing for high-predictability but not low-predictability stories. For the high-predictability stories they also quickly accepted an outcome that was contradictory to the intended inference. Results are interpreted in light of previous studies of RHD inferencing. One explanation that may reconcile seemingly contradictory findings involves the level activation of inferences.
PSEUDOFINITE H-STRUCTURES AND GROUPS DEFINABLE IN SUPERSIMPLE H-STRUCTURES

Abstract In this article we explore some properties of H-structures which are introduced in [2]. We describe a construction of H-structures based on one-dimensional asymptotic classes which preserves pseudofiniteness. That is, the H-structures we construct are ultraproducts of finite structures. We also prove that under the assumption that the base theory is supersimple of SU-rank one, there are no new definable groups in H-structures. This improves the corresponding result in [2].
Vegetation on mesic loamy and sandy soils along a 1700‐km maritime Eurasia Arctic Transect

Abstract Questions How do plant communities on zonal loamy vs. sandy soils vary across the full maritime Arctic bioclimate gradient? How are plant communities of these areas related to existing vegetation units of the European Vegetation Classification? What are the main environmental factors controlling transitions of vegetation along the bioclimate gradient? Location 1700‐km Eurasia Arctic Transect (EAT), Yamal Peninsula and Franz Josef Land (FJL), Russia. Methods The Braun‐Blanquet approach was used to sample mesic loamy and sandy plots on 14 total study sites at six locations, one in each of the five Arctic bioclimate subzones and the forest–tundra transition. Trends in soil factors, cover of plant growth forms (PGFs) and species diversity were examined along the summer warmth index (SWI) gradient and on loamy and sandy soils. Classification and ordination were used to group the plots and to test relationships between vegetation and environmental factors. Results Clear, mostly non‐linear, trends occurred for soil factors, vegetation structure and species diversity along the climate gradient. Cluster analysis revealed seven groups with clear relationships to subzone and soil texture. Clusters at the ends of the bioclimate gradient (forest–tundra and polar desert) had many highly diagnostic taxa, whereas clusters from the Yamal Peninsula had only a few. Axis 1 of a DCA was strongly correlated with latitude and summer warmth; Axis 2 was strongly correlated with soil moisture, percentage sand and landscape age. Conclusions Summer temperature and soil texture have clear effects on tundra canopy structure and species composition, with consequences for ecosystem properties. Each layer of the plant canopy has a distinct region of peak abundance along the bioclimate gradient. The major vegetation types are weakly aligned with described classes of the European Vegetation Checklist, indicating a continuous floristic gradient rather than distinct subzone regions. The study provides ground‐based vegetation data for satellite‐based interpretations of the western maritime Eurasian Arctic, and the first vegetation data from Hayes Island, Franz Josef Land, which is strongly separated geographically and floristically from the rest of the gradient and most susceptible to on‐going climate change.

A New Definition of Intuitionistic Fuzzy Similarity Degree

As far as the problem of intuitionistic fuzzy cluster analysis is concerned, this paper proposes a new formula of similarity degree with attribute weight of each index. We conduct a fuzzy cluster analysis based on the new intuitionistic fuzzy similarity matrix, which is constructed via this new weighted similarity degree method and can be transformed into a fuzzy similarity matrix. Moreover, an example is given to demonstrate the feasibility and validity of this method.
Moves to a Basic Income-Flat Tax System in Australia: Implications for the Distribution of Income and Supply of Labour

Problems with work disincentives and poverty traps apparent in the Australian tax-transfer system have led to a renewed debate about the advantages of universal benefits relative to means-tested benefits. This paper examines the implications of moving to a system where benefits are universal and the marginal tax rate schedule is simplified to a constant rate, refered to as a basic income — flat tax system. The Melbourne Institute Tax Transfer Simulator(MITTS), a behavioural micro-simulation model of the Australian tax-transfer system is used to examine the distributional,labour supply and government expenditure effects of moving to a basic income—flat tax system. Providing basic income levels that coincide with current benefit rates is costly, with a marginal tax rate of over fifty percent required for revenue neutrality. Such a system, while equitable, is found to reduce labour supply. If a version to inequality is high, this system is found to be socialy optimal, even after reductions in labour supply. Decreases in the marginal tax rate improve work incentives and increase the supply of labour, but increase inequality and impose a significant cost burden on government. A decline in the level of basic income of at least half is required to fund a reduction in the marginal tax rate to thirty percent. While the distortions to behaviour are minimal with this final system, it is extremely inequitable and social welfare reducing, even after a counting for changes in labour supply.
