Near-infrared fluorescent probe for visualization of nitroxyl in the plant response to stress.

Background: Nitroxyl (HNO) is an emerging signaling molecule that plays a significant regulatory role in various aspects of plant biology, including stress responses and developmental processes. However, understanding the precise actions of HNO in plants has been challenging due to the absence of highly sensitive and real-time in situ monitoring tools. Consequently, it is crucial to develop effective and accurate detection methods for HNO.

Synthesis, Thermal Stability and Antifungal Evaluation of Two New Pyrrole Esters.

To develop new chemicals that are stable at high temperatures with biological activity, a pyrrole intermediate was firstly synthesized using glucosamine hydrochloride as raw materials through cyclization and oxidation. Further, two novel pyrrole ester derivatives were prepared via Steglich esterification from pyrrole intermediate with vanillin and ethyl maltol, respectively. Nuclear magnetic resonance ( H-NMR, C NMR), infrared spectroscopy (IR) and high resolution mass spectrometry (HRMS) were used to confirm the target compounds.

Moisturizing and aroma-enhancing effects of low molecular weight fenugreek polysaccharides in cigarettes.

Polysaccharides possess excellent moisturizing effects due to their abundance of hydrophilic groups and film-forming properties. Additionally, they can produce a refreshing aroma during the pyrolysis process. However, there is scarce research on their application in the tobacco field.

Hydrogel-potassium humate composite alleviates cadmium toxicity of tobacco by regulating Cd bioavailability.

Cadmium (Cd) removal from soil to reduce Cd accumulation in plants is essential for agroecology, food safety, and human health. Cd enters plants from soil and affects plant growth and development. Hydrogels can easily combine with Cd, thereby altering its bioavailability in soil.

Ultrafine Pt nanoparticles anchored on core-shell structured zeolite-carbon for efficient catalysis of hydrogen generation.

Ammonia borane (AB) is a potential hydrogen storage material with high-efficiency hydrolytic dehydrogenation under a suitable catalyst. Noble metal catalysts have drawn a lot of attention. In this study, a carbon-coated zeolite was obtained by calcination at high temperatures using glucose as a carbon source.

Can Volunteering Buffer the Negative Impacts of Unemployment and Economic Inactivity on Mental Health? Longitudinal Evidence from the United Kingdom.

Previous research suggests that volunteering can mitigate the negative mental health impacts of unemployment but has yielded mixed results. This study extends the previous literature by examining whether volunteering can buffer the negative impacts of both unemployment and economic inactivity on mental health. Using nationally representative panel data from the United Kingdom Longitudinal Household Study (2010-2020) and fixed effects models, this study yields three important findings: First, volunteering cannot mitigate the adverse effects of unemployment, regardless of gender.

Biochar increases tobacco yield by promoting root growth based on a three-year field application.

In order to explore the effects of biochar on root system and growth characteristics of flue-tobacco, three years of field experiments were conducted to study the influence of different biochar application levels [600 (T), 1200 (T), 1800(T), 2400 (T), 3000 (T) kg/ha] and no fertilizer (CK) on the root physiological indexes and growth index of tobacco. Compared with local conventional fertilization, the application rate of N fertilizer in each treatment (except for control) was reduced by 40% to analyze the effects of different amount of biochar on the physiological indexes of tobacco roots and leaf photosynthesis during flourishing. The results showed that tobacco plants' root development status in the flourishing period was consistent with the photosynthetic physiological indexes, chlorophyll content, and leaf-area coefficient.

Mental Health and Depressive Feeling of Empty-nest Elderly People in China.

This paper reports on the first study in China that used nationally representative data to compare mental health and depressive feeling between empty-nest and non-empty-nest elderly people (over 60 years old), and examine whether the health disparities (if any) can be explained by differences in family, emotional, housework, and economic support. We used the 2010 China General Social Survey and multivariate regression models to examine mental health and depressive feeling of 556 non-empty-nest and 210 empty-nest elderly people in China. After controlling for various socio-demographic characteristics, although the empty-nest elderly were significantly more likely to report depressive feeling and poor mental health than non-empty-nest elderly, the difference was only statistically significant for depressive feeling.

Selenium Modulates the Level of Auxin to Alleviate the Toxicity of Cadmium in Tobacco.

Cadmium (Cd) is an environmental pollutant that potentially threatens human health worldwide. Developing approaches for efficiently treating environmental Cd is a priority. Selenium (Se) plays important role in the protection of plants against various abiotic stresses, including heavy metals.

Impact of International Immigration on Life Satisfaction of Local Residents in England: Exploring the Differentiated Relationships across Socioeconomic Gradients.

Large-scale influxes of international immigrants into England have stimulated heated debate about whether the increasing ethnic diversity has undermined local residents' life satisfaction and wellbeing. In this paper, we provide the first nationally representative evidence on the relationship between international immigration and local residents' life satisfaction in England. We used multilevel linear regression models to analyze nationally representative data (2011-2012) from 23,143 respondents and neighborhood level data from the 2011 Census.
