Comparing Fear of COVID-19 and Preventive COVID-19 Infection Behaviors Between Iranian and Taiwanese Older People: Early Reaction May Be a Key

This study assessed fear of the novel coronavirus-2019 (COVID-19), preventive COVID-19 infection behaviors, and the association between fear of COVID-19 and preventive COVID-19 infection behaviors among older people in Iran and Taiwan. Older people aged over 60 years (n = 144 for Iranians and 139 for Taiwanese) completed the Fear of COVID-19 Scale (FCV-19S) and two items on preventive COVID-19 infection behaviors (i.e., hand washing and mouth covering when sneezing). Iranian older people had a significantly higher level of fear of COVID-19 than did Taiwanese older people. Moreover, Iranian older people had significantly lower frequencies of preventive COVID-19 infection behaviors than did Taiwanese older people. Different timings in implementing COVID-19 infection control policies in Iran and Taiwan may explain why Iranian older people had greater fear of COVID-19 and lower preventive COVID-19 infection behaviors than did Taiwanese older people.
Kernel PCA with the Nyström method

The Nystr\"om method is one of the most popular techniques for improving the scalability of kernel methods. However, it has not yet been derived for kernel PCA in line with classical PCA. In this paper we derive kernel PCA with the Nystr\"om method, thereby providing one of the few available options to make kernel PCA scalable. We further study its statistical accuracy through a finite-sample confidence bound on the empirical reconstruction error compared to the full method. The behaviours of the method and bound are illustrated through computer experiments on multiple real-world datasets. As an application of the method we present kernel principal component regression with the Nystr\"om method, as an alternative to Nystr\"om kernel ridge regression for efficient regularized regression with kernels.
One-Step Preparation of Direct Electrochemistry HRP Biosensor via Electrodeposition

A horseradish peroxidase (HRP) biosensor was constructed by one step electrodeposition method and the direct electrochemistry of HRP in the biosensor was studied. In the biosensor HRP was immobilized on surface of the glassy carbon electrode (GCE) during the process of the gold nanoparticles (AuNPs) deposition with the help of surfactant cetyltrimethylammonium bromide (CTAB), through which HRP-CTAB-AuNPs/GCE was successfully constructed. HRP-CTAB-AuNPs/GCE can directly catalyze the reduction of peroxides without the electron mediator. SEM and electron dispersive spectroscopy (EDS) were used to characterize the modified electrode. The preparation process of the modified electrode was studied by electrochemical impedance spectroscopy. The electrochemical properties of the modified electrode to hydrogen peroxide, tert-butyl hydroperoxide and cumyl hydroperoxide were studied by electrochemical cyclic voltammetry and current-time curve. Results showed that the modified electrode exhibited good catalytic performances for the detection of hydrogen peroxide, tert-butyl hydroperoxide and cumyl hydroperoxide. The sensitivities for H2O2, tert-butyl hydroperoxide and cumyl hydroperoxide are 0.0187 AL/mol, 0.000340AL/mol and 0.0052 AL/mol, respectively. The detection limits are 2.3 × 10−7 mol/L, 8.6 × 10−6 mol/L and 3.6 × 10−6 mol/L, respectively.
Effectiveness of a Weight-Loss Intervention in Preventing Frailty and Functional Decline in Community-Dwelling Obese Older People. A Randomized Controlled Trial

Background Obesity is a risk factor for frailty and muscle weakness, so weight loss in obese older adults may prevent frailty and functional decline. Objective To assess the safety and efficacy of a multimodal weight-loss intervention in improving functional performance and reducing frailty risk in obese older adults. Design Randomized controlled trial with 2 parallel arms. SETTING AND PARTICIPANTS: Community-dwelling obese adults aged 65–75 years with body mass index (BMI) 30–39 kg/m 2 . INTERVENTION: 6-month multimodal intervention based on diet and a physical activity program. Control group: Usual care. Main and Secondary Outcome Measures Frailty (Fried criteria) rate and functional performance at 6, 12, and 24 months of follow-up, respectively. Intermediate Outcome Measures Weight loss, body composition changes, and metabolic and inflammatory biomarker changes. Results N=305. The study intervention increased gait speed at 12 and 24 months of follow-up, but had no significant effect on frailty prevention. It was effective in reducing weight, BMI, fat mass, interleukin 6, and insulin resistance and improving self-reported quality of life. Conclusions The study intervention was not demonstrated to be effective in preventing frailty in obese people aged 65–75 years at 24 months of follow-up. However, it allowed weight loss and a reduction in inflammatory and insulin resistance markers, which could have a long-term effect on frailty that requires further research.

Role of Diet in Modification of Gut Microbiota in Obesity: Review of Recent Literature

With the ever-increasing rate, obesity has become an epidemiological problem throughout the globe comprising about 39% of the world population as of now. Among several reasons, disruption of the gut microbial ecosystem might contribute to the pathogenesis of metabolic disorders, including obesity, metabolic syndrome, type 2 diabetes, and other associated comorbidities. Though the mechanisms related to dysbiosis are unclear, diet might play a modulating role where different dietary approaches manipulate microbial richness and abundance as well as stability. For instance, shifting of Firmicutes and Bacteroidetes ratio in the gut might have a role in association with the dietary approaches and ingestion duration. Along with altered gut microbial composition, microbial metabolites such as short-chain fatty acids (SCFA) after ingestion of non-digestible dietary starches may have an impact on host metabolism by regulating lipogenesis, gluconeogenesis, and inflammation with potential associations to health and obesity. The dietary approaches like carbohydrates, fibre, protein, and/or fat diet at various arrangements can make a shift in the composition of gut microbiota if introduced for a short period. However, the unique pattern of the gut microbes usually remains the same along with the longer period of habitual diet. Though the short-term dietary intervention or circadian rhythm influences a transient change in gut microbes, other than habitual diet, the understanding related to long-term dietary change-induced permanent alterations is minimum. Alternatively, the usage of prebiotics, probiotics as well as postbiotics could be beneficial to overcome dysbiosis. This review highlights the current knowledge and the interaction between the human intestinal microbiota and diet as a modifying factor, in obesity allowing the scientists to uncover novel targets and tools to use as customized therapy.
Risky Mortgages and Macroprudential Policy: A Calibrated DSGE Model for Lithuania

Following the financial crisis of 2009 there was an emergence of macroprudential policy tools, as well as a need to model the macroeconomy and the financial sector in a coherent framework. This paper develops and calibrates a small open economy DSGE model for Lithuania to shed some light on the interactions between the macroeconomy and the banking sector, regulated by macroprudential policy. The model features housing market, and endogenous credit risk a la de Walque et al. (2010), whereby the household can default on mortgage repayments, what leads to housing collateral seizure. Foreign-owned banks, that are subject to risk-sensitive macroprudential capital requirements, take into account not only the mortgage default rate but also the cap on loan to value (LTV) ratio when making lending decisions. Using this mechanism, we show that while a more stringent LTV constraint reduced credit demand, it can also lead to an expansion in credit supply via lower credit risk. Therefore, a tightening of LTV requirement should result in only a slight reduction in mortgage lending, coupled with lower interest rate margins. The article compares the impact of the tightening of three macroprudential tools, namely, bank capital requirements, mortgage risk weights and LTV limit. We find that broad-based capital requirements, such as the counter-cyclical capital buffer, are less efficient in leaning against the housing credit cycle, because of a relatively large cost incurred on the firm sector.

Effect Different Concentrations of Crude Oil on the Pigment Content and Protein Content of Hydrilla Verticillata Plant

The current study was conducted to determine the effect of crude oil on the pigments and protein content of Hydrilla verticillata plant from December 2018 to February 2019. Hydrilla verticillata was exposed to different concentrations of treatments (0.01,0.05,0.10,0.20) % of crude oil for 24 days. The pigments content was evaluated as total chlorophyll, a, b, carotene and protein content within plant tissues during the days (1, 8, 16 and 24). The results of this study showed an increment in the total chlorophyll values of plant, which is exposed to different concentrations of crude oil compared to the control treatment during the first day of the experiment and decreased compared to control treatment during 8,16 and 24 days of the experiment. The recorded maximum value of total chlorophyll was (29.49) Î¼g / g at 0.10% treatment during the first day and the statistical analysis showed significant differences below the probability level (P> 0.05) between the concentrations and the days of the experiment. Chlorophyll a, b and carotene of plant exhibit the overall trend of total chlorophyll. The values of chlorophyll b were higher than the values of chlorophyll and carotene. The current study showed a gradual decrease in the total protein values of plants in crude oil during experiential period compared to control treatment, recording the highest values at the 0.01% during the first day (29.4 mg/g) and the lowest in the concentration of 0.05% during the day 24 was (3.5) mg / g, and the statistical analysis showed significant differences below the probability level (P> 0.05) between the days and concentrations of the experiment. The study concluded that a gradual decrease of total chlorophyll values during period experimental, recorded the chlorophyll b values higher compare to chlorophyll a and carotene. the gradual decrease of protein values with the increasing the concentration.

Miguel J Franquiz 1,2 Nicholas J Short 1Baylor College of Medicine, Houston, TX, USA; 2Department of Leukemia, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Several therapeutic advancements in the treatment of B-cell acute lymphoblastic leukemia (ALL) have surfaced in the past decade, primarily driven by an increased understanding of the immunopathobiology of this disease. The clinical use of blinatumomab, a bispecific antibody that coordinates cytotoxic CD3+ T lymphocytes and CD19+ lymphoblasts, has resulted in improved outcomes in both relapsed/refractory and minimal residual disease-positive B-cell ALL. Promising emerging data also demonstrate the efficacy of this agent in the frontline setting and in combination regimens. Uncertainty remains regarding the optimal sequencing and combination of blinatumomab with cytotoxic chemotherapy and other emerging agents. The pharmacology and clinical data on blinatumomab for adult B-cell ALL, both as monotherapy and in combinations, will be reviewed herein.
Dynamics of diatomic molecules on metal surfaces: O2/Ag(110) and CO/Ru(0001)

This thesis concerns with theoretical modelling from first principles of dynamics of two gas-surface systems (oxygen on silver and carbon monoxide on ruthenium) that are relevant to the heterogeneous catalysis. An accurate potential energy surface is constructed for the interaction of molecular oxygen with the Ag(110) surface based on density functional theory calculations. Using this potential energy surface, the dissociative and molecular adsorption dynamics is studied by performing trajectory calculations. Accuracy of different approximations to exchange-correlation functional in density functional theory for the modelling of the oxygen-silver system is tested. Furthermore, laser induced desorption of oxygen from Ag(110) is studied. Dynamics of carbon monoxide adsorption and scattering on Ru(0001) is also studied by performing trajectory calculations on top of a density functional based potential energy surface. These simulations can explain the results of molecular beam experiments.
Regional, multi-decadal analysis reveals that stream temperature increases faster than air temperature

Abstract. Stream temperature appears to be increasing globally, but its rate remains poorly constrained due to a paucity of long-term data and difficulty in parsing effects of hydroclimate and landscape variability. Here, we address these issues using the physically-based thermal model T-NET (Temperature-NETwork) coupled with the EROS semi-distributed hydrological model to reconstruct past daily stream temperature and streamflow at the scale of the entire Loire River basin in France (105 km2 with 52278 reaches). Stream temperature increased for almost all reaches in all seasons (mean = +0.38 °C/decade) over the 1963–2019 period. Increases were greatest in spring and summer with a median increase of +0.38 °C (range = +0.11– +0.76 °C) and +0.44 °C (+0.08– +1.02 °C) per decade, respectively. Rates of stream temperature increases were greater than for air temperature across seasons for 50–86 % of reaches. Spring and summer increases were typically the greatest in the southern headwaters (up to +1 °C/decade) and in the largest rivers (Strahler order > 5). Importantly, air temperature and streamflow exerted joint influence on stream temperature trends, where the greatest stream temperature increases were accompanied by similar trends in air temperature (up to +0.71 °C/decade) and the greatest decreases in streamflow (up to −16 %/decade). Indeed, for the majority of reaches, positive stream temperature anomalies exhibited synchrony with positive anomalies in air temperature and negative anomalies in streamflow, highlighting the dual control exerted by these hydroclimatic drivers. Moreover, spring and summer stream temperature, air temperature, and streamflow time series exhibited common change-points occurring in the late 1980s, suggesting a temporal coherence between changes in the hydroclimatic drivers and a rapid stream temperature response. Critically, riparian vegetation shading mitigated stream temperature increases by up to 16 % in smaller streams (i.e., < 30 km from the source). Our results provide strong support for basin-wide increases in stream temperature due to joint effects of rising air temperature and reduced streamflow. We suggest that some of these climate change-induced effects can be mitigated through the restoration and maintenance of riparian forests, and call for continued high-resolution monitoring of stream temperature at large scales.
PREVALENCE, ETIOLOGY AND ANTIBIOGRAM OF MASTITIS IN BUFFALOES IN SOHAG GOVERNORATE

In this study total of 416 milk samples (104 buffaloes) which were reared in a smallholder private cases hand milked in Sohag Governorate were examined. Clinical screening of examined animals beside the results of California mastitis test for apparentely healthy animals revealed that the overall prevalence rate of clinical and subclinical mastitis were 22.1% and 26.9%, respectively. The incidence of one quarter infection was the highest followed by all quarters in clinical and subclinical mastitis cases at the percentage of 30.4%, 35.7%, 26.2% and 28.6% respectively. The third lactating season was the highest incidence of both clinical and subclinical mastitis at the percentage of 28.6% and 35.3% respectively. By bacteriological examination 56 isolates from clinical mastitic cases and 68 isolates from subclinical mastitic animals were detected. Staphylococcus aureus , E.coli and , Streptococcus agalactia were isolated by ratio 16.1%, 33.9%, 14.3% and 29.4%, 22.1%,10.3 in cases of clinical mastitis and subclincal ones respectively. staphylococcus aureus and E. coli staphylococcus aureus and streptococcus agalactia and staphylococcus aureus and E-coli microorganisms were mixed isolated by ratio 7.1%, 7.1% and 5.4% in cases of clinical mastitis and 8.8%,4.4%, 4.4% in subclinical mastitic cases. Mixing of more than 3 isolates or more was the rate of clinical mastitis 8.9%, whereas subclinical mastitic were 8.8%. Simplex and multiplex PCR assays showed that E-coli isolates were the highest causative agents of clinical mastitis and staphylococcus aureus was the major cause of subclinical mastitic ones. Antimicrobial susceptibility testing revealed that all isolates were highly sensitive to Gentamycin Ceprofloxacin, Lincomycin and Novobiocin followed by Chloramphenicol, Cephalothin and Amoxycillin.
Does Real-Time Feedback Affect Sensorimotor EEG Patterns in Routine Motor Imagery Practice?

Background. Motor imagery engages much of the same neural circuits as an overt movement. Therefore, the mental rehearsal of movements is often used to supplement physical training and might aid motor neurorehabilitation after stroke. One attempt to capture the brain’s involvement in imagery involves the use, as a marker, of the depression or event-related desynchronization (ERD) of thalamocortical sensorimotor rhythms found in a human electroencephalogram (EEG). Using fast real-time processing, it is possible to make the subject aware of their own brain reactions or—even better—to turn them into actions through a technology called the brain–computer interface (BCI). However, it remains unclear whether BCI-enabled imagery facilitates a stronger or qualitatively different brain response compared to the open-loop training. Methods. Seven healthy volunteers who were experienced in both closed and open-loop motor imagery took part in six experimental sessions over a period of 4.5 months, in which they performed kinesthetic imagery of a previously known set of finger and arm movements with simultaneous 30-channel EEG acquisition. The first and the last session mostly consisted of feedback trials in which the subjects were presented with the classification results of the EEG patterns in real time; during the other sessions, no feedback was provided. Spatiotemporal and amplitude features of the ERD patterns concomitant with imagery were compared across experimental days and between feedback conditions using linear mixed-effects modeling. Results. The main spatial sources of ERD appeared to be highly stable across the six experimental days, remaining nearly identical in five of seven subjects (Pearson’s ρ > 0.94). Only in one subject did the spatial pattern of activation statistically significantly differ (p = 0.009) between the feedback and no-feedback conditions. Real-time visual feedback delivered through the BCI did not significantly increase the ERD strength. Conclusion. The results imply that the potential benefits of MI could be yielded by well-habituated subjects with a simplified open-loop setup, e.g., through at-home self-practice.
Elastic Frustration in 1D Spin-Crossover Chains: Evidence of Multi-Step Transitions and Self-Organizations of the Spin States

We consider a 1D elastic spin-crossover (SCO) chain in which each site may be in the low-spin or in the high-spin (HS) state. The sites interact elastically through a harmonic coupling, and the local equilibrium distances depend on the spin states of the interacting sites. The Hamiltonian of the system is solved by the Monte Carlo method running on the spin states and the atomic displacements. By considering the existence of an elastic frustration between the equilibrium distances of the nearest-neighbors and the next-nearest-neighbors, we succeeded to highlight a number of original behaviors of the thermal dependence of the high-spin fraction, like multistep transitions, incomplete spin transitions, emergence of self-organized structures, and re-entrant spin transitions, by adjusting only one control parameter. The obtained results allow understanding several experimental data of 1D spin-crossover materials which seem to be model systems for elastic frustration.
