This article provides practical guide based on how to use telemedicine and virtual care during the COVID-19 pandemic. This study provides implication on the potentials of consolidating virtual care solutions in the near future towards contributing to integrate digital technologies into healthcare.The study of subjective well-being (SWB) has attracted considerable attention from scholars globally. This has stimulated numerous studies that have identified regional and individual factors associated with SWB, but the extant research lacks multi-level studies that simultaneously examine their influence on SWB. Environmental pollution is one of such factors, but few studies have investigated its effect on SWB in China particularly. The current study addressed these problems by conducting hierarchical linear regressions to explore the effects of regional and individual factors on Chinese people's SWB. Three major environmental pollutions (wastewater pollution, domestic waste pollution, and air pollution) were studied using data from the Chinese General Social Survey 2013 and China Statistical Yearbook 2014. The results indicated that wastewater pollution and domestic waste pollution had significant negative influence on SWB. Moreover, gross domestic product (GDP) per capita might contribute more to the improvement of SWB than income inequality. This implies that individuals' SWB might be enhanced by improving absolute income, which is consistent with the micro-level proposition of the Easterlin paradox. Overall, these findings signal that effective management of environmental pollution is essential for promoting the SWB of the people in China.This study investigates the impact of an engineered magnetic nanoparticle (MNP) on a crop plant. For this purpose, a sonochemical synthetic approach was utilized in order to dope magnetic elements (Co and Nd) into technologically important iron oxide NPs. After being characterized by using TEM, SEM, and XRD instruments, the MNPs were hydroponically applied to barley plants with varying doses (from 125 to 1000 mg/L) both in germination (4 days) and early growing stages (3 weeks). Physiological responses, as well as expression of photosystem marker genes, were assessed. Compared to the untreated control, MNP treatment enhanced germination rate (~ 31%), tissue growth (8% in roots, 16% in shoots), biomass (~ 21%), and chlorophyll (a, b) (~ 20%), and carotenoids (~ 22%) pigments. In general, plants showed the highest growth enhancement at 125 or 250 mg/L treatment. However, higher doses diminished the growth indices. [https://www.selleckchem.com/products/ri-1.html RI-1] Compared to the control, the catalase activity was significantly reduced in the leaves (~ 33%, p less then 0.005) but stimulated in the roots (~ 46%, p less then 0.005). All tested photosystem marker genes (BCA, psbA, and psaA) were overexpressed in MNP-treated leaves than non-treated control. Moreover, the gene expressions were found to be proportionally increased with increasing MNP doses, indicating a positive correlation between MNPs and the photosynthetic machinery, which could contribute to the enhancement of plant growth.The coastal sediments in the northern Bay of Bengal has undergone contamination due to the heavy metal contribution from rivers. To evaluate the status of contamination in the inner shelf region of the Bay of Bengal, a sediment core chronologically constrained using 210Pb dating technique from the northwest Bay of Bengal was investigated for several trace elements. To assess sediment quality, enrichment factor (EF), geo-accumulation index (Igeo), and Modified Nemerow Pollution Index (MPI) were derived. The influence on ecology by individual contaminants and combined contaminants was evaluated using the potential ecological risk factor (Eri) and modified ecological risk index (MRI). The single-element pollution indices indicated that the sediment has no significant pollution by individual elements. However, the multi-elemental approach shows slight pollution in the sediment core. The ecology is at low risk by contaminants present in the sediment. Comparison of the elemental values of shelf sediment with adjacent riverine and estuarine samples demonstrates the role of estuarine environment and/or high riverine flux of sediments causing either removal or dilution of trace elements during its transport from the river to the sea.China has suffered from extensive and serious SO2 pollution. The central and provincial governments have reinforced environmental awareness by increasing fiscal expenditure for environmental protection for years. This paper extended an environmental Kuznets curve (EKC) framework to evaluate the direct and indirect spillover effects of environmental awareness of provincial governments on SO2 emissions, applying spatial econometric models. The empirical findings are as follows. (1) There exists an inverted U-shaped curve. Of 30 Chinese provinces, only 9 provinces, namely, 8 eastern provinces and Inner Mongolia, have passed the turning point at about 53,000 Yuan while the rest 21 provinces have not yet. (2) Expenditure for environmental protection is negatively correlated with SO2 pollution. In other words, environmental awareness of governments contributes to substantially reducing SO2 emissions. Besides, significant and negative spillover effects of environmental awareness are found, implying that provinces follow suit if neighboring provinces enhance environmental awareness by increasing spending on environmental protection, thereby reducing SO2 emissions. (3) The SO2 reduction policy implemented by the central government is found to have a negative impact on SO2 emissions, implying that the policy effectively works. To conclude, the central and provincial governments play pivotal roles in addressing the problem of SO2 pollution in China. Hence, more expenditure for environmental protection cannot be overstated for China's environmental quality improvements and sustainable development.Background Hyperparathyroidism substantially impairs quality of life, and effective treatment depends on timely referral to surgeons. We hypothesized that there would be race and gender disparities in the time from initial diagnosis of hyperparathyroidism to treatment with parathyroidectomy. Methods We reviewed administrative data on 2289 patients with hypercalcemia (calcium &gt; 10.5 mg/dL) and abnormal parathyroid hormone levels who were seen at a tertiary referral center from 2011 to 2016. We used two-phase parametric hazard modeling to identify predictors of time from index abnormal calcium until parathyroidectomy. Results The median age of our cohort was 63 years, and 1685 (74%) were women. Of the total patients, 1301 (57%) were Caucasian, and 946 (41%) were African-American. Only 490 (21%) patients underwent parathyroidectomy. Among patients undergoing surgery, time from index high calcium to surgical treatment was longest for African-American men, who waited a median of 13.6 months (interquartile range IQR 2-28), compared with 2.
