Anti-Spike protein assays to determine post-vaccination antibody levels: a head-to-head comparison of five quantitative assays

Background Reliable quantification of the antibody response to SARS-CoV-2 vaccination is highly relevant for identifying possible vaccine failure and estimating the time of protection. Therefore, we aimed to evaluate the performance of five different Anti-SARS-CoV-2 antibody assays regarding the quantification of anti-spike (S) antibodies induced after a single dose of BNT162b2. Methods Sera of n=69 SARS-CoV-2 naive individuals 21+/-1 days after vaccination with BNT162b2 (Pfizer/BioNTech) were tested using the following quantitative SARS-CoV-2 antibody assays: Roche S total antibody, DiaSorin trimeric spike IgG, DiaSorin S1/S2 IgG, Abbott II IgG, and Serion/Virion IgG. Test agreement was assessed by Passing-Bablok regression. Results were further compared to the percent inhibition calculated from a surrogate virus neutralization test (sVNT) by correlation and ROC (receiver-operating-characteristics) analysis. Results Individual values were distributed over several orders of magnitude for all assays evaluated. Although the assays were in good overall agreement (rho=0.80-0.94), Passing-Bablok regression revealed systematic and proportional differences, which could not be eliminated by converting the results to BAU/mL as suggested by the manufacturers. 7 (10%) individuals had a negative sVNT results (i.e. <30% inhibition). These samples were reliably identified by most assays and yielded low binding antibody levels (ROC-AUCs 0.84-0.93). Conclusions Although all assays evaluated showed good correlation, readings from different assays were not interchangeable, even when converted to BAU/mL using the WHO international standard for SARS-CoV-2 immunoglobulin. This highlights the need for further standardization of SARS-CoV-2 serology.
Development of a rheological method to characterize palm oil crystallizing under shear

To follow palm oil crystallization under shear, a new rheological method was developed. This method can be split up into two parts: In the first part, continuous shear is applied for a pre-defined period and crystallization is monitored by measuring the apparent viscosity as a function of isothermal time under shear. In the second part, shear is halted and oscillation is applied during 30 s, thus recording moduli and phase angle. These moduli and phase angle are then characteristic of a sample crystallized under shear during this pre-defined period. After repeating this procedure for increasing shearing periods in the first part, complex modulus and phase angle were plotted as a function of isothermal time under shear. The thus obtained results were compared with crystallization data obtained via time-resolved X-ray diffraction and polarized light microscopy.
Effect of Salicylic Acid and Potassium Nitrate on Growth and Yield of Lentil (Lens culinaris L.) under Rainfed Condition

Pulses are among the most important crops which are considered as substitutes for animal protein among the vegetarian population and it also occupy special place in diets of the Indian population. They are known to render significant impact on soil health and considered to be key component for sustainable agriculture. Pulses have the capacity to fix the soil atmospheric nitrogen in their root system, which enables the plants to meet the nitrogen requirement on its own. Lentil is one of the major rabi pulses in India which contributes about 6% of the total area under pulse as well as production in India.

Financial Sector Reform and Economic Development in Nigeria

Various reforms have been brought to bear on the financial system ostensibly to improve the countryâs macroeconomic variables and the standard of living of the people, among which are the financial reforms that were implemented in recent times. This study examines the impact of financial sector reform on the Human Development Index (HDI) following the recent statistics that show improvement in the HDI of Nigeria since 2005. The study employed several variables as a proxy for financial reforms and adopted the Granger causality test and vector error correction model to analyse the impact of the relationship for the period between 1980 and 2017. The findings revealed a negative long-run relationship between financial sector reform variables and HDI, except for ownersâ equity. The study also showed positive short-run dynamics between total savings to GDP and HDI. The study concluded that the recent improvements in HDI, which is the proxy for economic development, are not due to the financial sectorâs reforms; rather, some other influences in the economy could be responsible. The study, therefore, recommends a more inclusive reform agenda that will focus on economic development rather than economic growth.

Forage production and productive performance of Nellore heifers in agrosilvopastoral systems Produção de forragem e desempenho produtivo de novilhas Nelore em sistemas agrossilvopastoris Producción de forrajes y desempeño productivo de novillas Nelore en sistemas agrossilvopastoriles

Agrosilvopastoral system is a type of production that involves the soil-forage-animal interface, both of which are benefited by the system. Hence, the present study evaluated the effects of agrosilvopastoral system on the quantitative and qualitative characteristics from pasture, and the animal performance during the feeding period of Nellore heifers. The treatments included: Soil-forage-animal – 357 eucalyptus trees per hectare (LFA14x2m); Soilforage-animal – 227 eucalyptus trees per hectare (LFA22x2m); and Soil-animal – Five native trees remaining per hectare (CON). The forage used was Brachiaria brizantha cv. BRS Piatã and having as trees planted the Eucalyptus urograndis clones H 13. Treatment effects (P <0.05) for forage accumulation and pasture height, which were lowest in LFA14x2m compared to the others. Total forage dry mass in CON treatment was significantly greater (P <0.05) compared to the other treatments, showing maximum production in March. The LFA14x2m treatment was favorable for greater forage quality, showing an effect on chemical composition (P <0.05), compared to other treatments. Whereas, in November the LFA22x2m treatment was better for neutral detergent fiber. January and March, the treatments were similar (P >0.05) for average daily gain, while in November period, LFA14x2m treatment showed the lowest value (P <0.05). The lowest weight gain by area (November) occurred in the LFA14x2m treatment (P <0.05), although in March the LFA14x2m treatment stocking rate was similar to the others. Forage production and animal performance are altered by the trees densification in agrosilvopastoral systems. The chemical composition of pasture is better in systems with a higher trees density.
Human erythrocyte surface fucose expression increases with age and hyperglycemia

Background: Reactive oxygen species and other free radicals, together with glucose and its metabolites are believed to play important roles in the aging process. The carbohydrate components of glycosylated proteins are important in mediating cell-cell interactions and a role has been suggested for them in the aging process. Erythrocytes are critical cells in the human body, heavily glycosylated and relatively easily available and so are good candidates to yield insights into how patterns of glycosylation change with age and disease. It has been claimed, based on a periodic acid Schiff assay, that human aging is associated with a decline of erythrocyte surface sialic acids. Plant lectins allow for more specific assays for glycans, including determining the linkage of sialic acids and analysis of single cells by flow cytometry. Methods: Plant lectins, including Maackia amurensis lectin II (MAL), binding to α-2,3 linked sialic acids and Sambucus nigra (SNA), α-2,6 sialic acids, were used in flow cytometry and western blot of erythrocyte surface membrane. N-glycomics mass spectrometry determines glycan structures. Donors varying in age and hyperglycemia, as indicated by HbA1c were analysed. Results: Erythrocyte surface sialic acids have no significant associations with donor age. A combination of storage and cellular aging produces a specific loss of α-2,6 sialic acids. By contrast, erythrocyte surface terminal fucoses increase significantly with donor age. In order to determine which aspects of aging are important in determining this change, we investigated whether this novel human aging biomarker is associated with higher plasma glucose values, assessed by glycated hemoglobin (HbA1c) and reactive oxygen species (ROS) generation. Fucose levels were associated with HbA1c levels, but not ROS generation. Conclusion: Our study identifies novel glycan-based biomarkers for human aging and disease. The simplicity of lectin-based assays provide an attractive cellular tool to study aging and disease processes.

Firmness Evaluation by Drop Impact Characteristics for Peach

The peach dynamic resonance frequencies were obtained based on the analysis of dynamically measured response signal of an drop-excited peach with change in impacted orientation, drop height, material of impact surface, peach firmness, peach mass, and storage time of peach. After peach was impacted, response signals in time domain were detected, and transformed into frequency domain (by means of FFT). The dominant frequency (the response magnitude were the greatest) was obtained and significantly affected by peach firmness, mass, and storage time. The impacted orientation, drop height, and material of impact surface did not significantly affect the dominant frequency. The dominant frequency increased with increasing of peach firmness and decreased with increasing of peach mass. The relationships were obtained between dominant frequency and peach firmness or peach mass, and the stiffness coefficient (Sc = f2m2/3 ) regressed on Magness-Taylor firmness had a better relationship. The peach firmness could be predicted by drop impacting method.
Causal and Interpretable Learning for Datacenter Latency Prediction

Stragglers—computations that exhibit extreme tail latencies—present a major challenge to delivering predictable performance in datacenters. Accurately predicting stragglers would enable e ﬃ cient, proactive intervention. While a number of approaches use machine learning to predict computer system performance, they routinely rely on carefully curated training sets . Assembling the right training set requires prior knowledge, i.e., su ﬃ cient examples of all possible behaviors to be identiﬁed, which is challenging when new workloads could be unique and unlike any workload from training. To make accurate predictions with neither prior knowledge nor carefully curated datasets this paper presents Agatha, a straggler prediction framework that augments existing machine learning approaches with causal analysis. Agatha weights predictions using a statistical method—called propensity scoring—to account for a lack of stragglers in training data. Additionally, Agatha exploits model-agnostic interpretation to gain insights into the reasons for straggling behavior. We evaluate Agatha on datacenter traces from Google and Alibaba and ﬁnd that, compared to prior work that is heavily reliant on the training set, Agatha (1) produces much more accurate predictions, (2) does so much earlier in job execution, (3) provides interpretable results, and (4) reduces completion time. Agatha achieves these improved predictions even with no examples of stragglers in its training set, making it better suited for practical deployments.
Towards Ending the HIV Epidemic in the US: State of Human Immunodeficiency Virus Screening during Physician and Emergency Department Visits, 2009 -2014

Human immunodeficiency virus (HIV) testing is important for prevention and treatment. Ending the HIV epidemic is unattainable if significant proportions of people living with HIV remain undiagnosed, making HIV testing critical for prevention and treatment. The Centers for Disease Control and Prevention (CDC) recommends routine HIV testing for persons aged 13 to 64 years in all health care settings. This study builds on prior research by estimating the extent to which HIV testing occurs during physician office and emergency department (ED) post 2006 CDC recommendations. We performed an unweighted and weighted cross-sectional analysis using pooled data from 2 nationally representative surveys namely National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 2009 to 2014. We assessed routine HIV testing trends and predictive factors in physician offices and ED using multi-stage statistical survey procedures in SAS 9.4. HIV testing rates in physician offices increased by 105% (5.6–11.5 per 1000) over the study period. A steeper increase was observed in ED with a 191% (2.3–6.7 per 1000) increase. Odds ratio (OR) for HIV testing in physician offices were highest among ages 20 to 29 ([OR] 7.20, 99% confidence interval [CI: 4.37–11.85]), males (OR 1.34, [CI: 0.91–0.93]), African-Americans (OR 2.97, [CI: 2.05–4.31]), Hispanics (OR 1.80, [CI: 1.17–2.78]), and among visits occurring in the South (OR 2.06, [CI: 1.23–3.44]). In the ED, similar trends of higher testing odds persisted for African Americans (OR 3.44, 99%CI 2.50–4.73), Hispanics (OR 2.23, 99%CI 1.65– 3.01), and Northeast (OR 2.24, 99% CI 1.10–4.54). While progress has been made in screening, HIV testing rates remains sub-optimal for ED visits. Populations visiting the ED for routine care may suffer missed opportunities for HIV testing, which delays their entry into HIV medical care. To end the epidemic, new approaches for increasing targeted routine HIV testing for populations attending health care settings is recommended.

Wireless Communication using VLC and MIMO Technology

: Due to the rapid growths in Light Emitting Diodes, VLC (Visible Light Communication) has received a great attention in last years. Our main aim of this research work is to build the wireless VLC (Visible Light Communication) system which should be able to transmit the data in-between two computers with the use of a visible light. We are using an LED array as the transmitter, Light Dependent Resistor (LDR) as the receiver component and air as the transmission medium. In both the transmitter and receiver modules, we are using Arduino UNO microcontroller board. Two computers have been used to interface the software to the hardware with the help of Arduino IDE installed to both of them. If we want to check the performance of VLC system with MIMO, commercial optical system simulation software called OptiSystem7.0 from Optiwave can be used. The layout diagram for both SISO (Single Input Single Output) and MIMO (Multiple Input Multiple Output) communication has been generated and has been run and the BER (Bit Error Rate) performance is being analyzed. FSO (Free Space Optical) communication channel is used as transmission medium for both SISO and MIMO. Data transmission and reception for 100 meters is done using OptiSystem software. The eye diagram of BER analyzer showed that the maximum quality factor of MIMO is relatively large when compared to SISO .
Spectral relationship of light-induced refractive index and absorption changes in bacteriorhodopsin films containing wildtype BRWT and the variant BRD96N

Bacteriorhodopsin films containing the variant BR D96N , which differs from the wildtype BR WT by a single amino acid exchange, Asp 96→Asn, show significantly higher holographic diffraction efficiencies(η) than BR WT films. The light-induced changes of both the absorption a(λ,I) and the refractive index n(λ,I), which influence the diffraction efficiency η(λ,I), have been investigated, and their spectral dependence has been measured in order to analyze both parameters separately
The Influence of Compositional Factors and Contextual Factors in the Incidence of Hypertension in Medan City, Indonesia

Background: Hypertension is a common health problem in Medan, and its prevalence remains high. Compositional and contextual factors play a role in the incidence of hypertension.Aims: The aim of this study was to analyze the influence of compositional and contextual factors on the incidence of hypertension.Settings and Design: This was an observational study with an unmatched case-control design.Methods and Materials: The sample included 208 recruits at a case-to-control ratio of 1:1 who were selected using fixed disease sampling. Data were collected by interviews and measurements.Statistical analysis: Data were analyzed using multiple logistic regression with a multilevel analysis approach.Results: The majority of respondents (169) were aged 40 years or older (81.2%), 156 were female (75.0%), 117 had higher education (56.3%), 105 were low income (51.0%), 150 had no family history (72.1%), 119 were overweight (57.2%), 136 had no smoking habit (65.4%), and 124 were physically inactive (59.6%). Compositional factors including an age of 40 years or older (OR 7.014, 95% CI 2.70, 18,21), low education (OR 1.86, 95% CI 1.01, 3.41), and overweight (OR 2.35, 95% CI 1.28, 4.30) contributed as much as 49.6% to the incidence of hypertension in Medan. Variation in the incidence of hypertension was determined by household characteristics.Conclusions: Compositional factors contributed to the incidence of hypertension (49.6%). Intervention programs should be primarily focused on compositional factors such as losing weight and maintaining an ideal body weight by intensifying health promotion.
Building Information Modeling (BIM) in Enhancing the Applying of Knowledge Areas in the Architecture, Engineering and Construction (AEC) Industry

The Architecture, Engineering, and Construction (AEC) industry is one of the sectors that contribute the most to the Palestinian economy. However, it now suffers from many problems, one of which is not adopting new innovations, such as Building Information Modeling (BIM). BIM recently achieved far reaching consideration in the AEC industry. This research aimed to understand the contribution of BIM to the enhancement and application of Knowledge Areas (KAs) in the AEC industry in Palestine. A quantitative survey was utilized in the pilot study. Thirty copies of the questionnaire were dispersed to respondents from the target group. The completed questionnaires were analyzed to test for statistical validity and reliability. After the pilot study, the questionnaire was validated and dispersed to the entire sample, comprising respondents from the target group who were selected by convenience sampling. Eighty copies of the questionnaire were dispersed, and 71 copies of the questionnaire were obtained from the respondents with a response rate of 88.8%. To draw meaningful results, the gathered information was analyzed by utilizing quantitative data analysis techniques, including the RII, Pearson correlation analysis, and Factor analysis. The results illustrated the extent of enhancing the application of KAs in the AEC industry using BIM technology from the highest to lowest as follows: Cost Management (CM), Time Management (TM), Resource Management (REM), Procurement Management (PROM), Scope Management (SCM), Stakeholder Management (STM), Integration Management (IM), Quality Management (QM), Communication Management (COM), Risk Management (RM), and Safety Management (SM). As an example, BIM is effectively applied to each KA, and high efficiency is achieved when BIM is applied to TM by 4D modeling; to CM by 5D modeling; to REM by collaboration; to PROM by quantity takeoff; to SCM by element-base; to STM and IM by using integrated project delivery; to QM by using clash detection; to COM by centralized, structured data management, and information flow; to RM by constructability; and to SM by automated safety code checking.
Time-resolved resonance Raman elucidation of the pathway for dioxygen reduction by cytochrome c oxidase

Time-resolved resonance Raman (RR) spectra were observed for catalytic intermediates of bovine cytochrome c oxidase at room temperature by using an Artificial Cardiovascular System for Enzymatic Reactions and Raman/Absorption Simultaneous Measurement Device. The isotope-frequency-shift data using an asymmetrically labeled dioxygen, [sup 16]O[sup 18]O, established that the primary intermediate (compound A) is an end-on-type dioxygen adduct of cytochrome a[sub 3]. Higher resolution RR experiments revealed that the approximately 800-cm[sup [minus]1] band assigned previously to the Fe[sup TV]= O stretching mode of the subsequent intermediate (compound B) was actually composed of two bands that behaved differently upon deuteration. The 804/764-cm[sup [minus]1] pair for the [sup 16]O[sub 2]/[sup 18]O[sub 2] derivatives were insensitive to deuteration, and these bands became noticeably stronger at higher temperatures. The present experiments have conclusively established that the main pathway for dioxygen reduction by cytochrome c oxidase is Fe[sup II]-O[sub 2] [yields] Fe[sup III]-O-O-H [yields] Fe[sup IV]=O [yields] Fe[sup III]-OH and that their key bands for the [sup 16]O[sub 2]/[sup 18]O[sub 2] pair are at 571/544, 785/751, 804/764, and 450/425 cm[sup [minus]1], respectively. 79 refs., 8 figs., 3 tabs.
