Although Ahvaz is considered as one of the warmest cities around the world, few epidemiological studies have been conducted on the adverse effects of temperature on human health using thermal indices in this city. This study investigates the relation between physiologically equivalent temperature (PET) and respiratory hospital admissions in Ahvaz. Distributed lag non-linear models (DLNMs) combined with quasi-Poisson regression models were used to investigate the relation between PET and respiratory disease hospital admissions, adjusted for the effect of time trend, air pollutants (NO2, SO2, and PM10), and weekdays. The analysis was performed by utilizing R software. Low PET values significantly decreased the risk of hospital admissions for total respiratory diseases, respiratory diseases in men and women, chronic obstructive pulmonary diseases (COPD), and bronchiectasis. However, low PET (16.9°C) in all lags except lag 0-30 significantly increased the risk of hospital admissions for asthma. The results indicate that in Ahvaz, which has a warm climate, cold weather decreased overall respiratory hospital admissions, except for asthma.The roles of land scale and household labor allocation have always been a hot button in nitrogen (N) fertilizer use. Rural part-time farming is the main form of household labor allocation in China. This study aimed to quantify the N fertilizer use responses to land-scale expansion and rural part-time farming with different degrees and types in Chinese croplands. Using data on 1159 households extracted from a rural household survey in three great agricultural plains, China, we applied Ordinary Least Squares and Tobit model to yield the consistent results. The results showed that N fertilizer use significantly decreases by 2.23 kg/ha with per unit increase in land scale (p less then 0.1), while rural part-time farming degree significantly increases N fertilizer use by 29.72 kg/ha (p less then 0.01). Particularly, different effects are detected on the different types of part-time farming households. PTF II (part-time farming degree ranges from 50% to 80%) and OFH (degree higher than 80%) types are proved to be responsible for increasing N fertilizer use of 25.41 kg/ha (p less then 0.01) and 22.86 kg/ha (p less then 0.05), respectively. These findings imply that the government should encourage part-time farming households to transfer agricultural croplands, thereby expanding land scale so as to reduce N fertilizer use.Since energy is one of the basic inputs for development, emerging economies should make an effort to investigate the environmental impacts of their fast economic growth. However, large emerging economies present significant regional heterogeneity that is usually uncounted for. This study uses the Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model and regional data on the 27 Brazilian states to investigate the growth-CO2 nexus under distinct development stages. https://www.selleckchem.com/products/Nevirapine(Viramune).html To perform this analysis, we divided the states into three groups according to their average annual GDP (i.e., richer, intermediate, and poorer regions). The results suggest that richer and poorer regions, particularly, present economic and demographic developments that are environmentally costly. Also, population and per capita GDP have the largest influences on CO2 emissions. The roles of the industrial sector and the ascending service sector are also subject to criticism. Moreover, Brazil arguably suffers from technological stagnation as its energy intensity is growing and boosting CO2 emissions. We discuss the policy implications of these findings and suggest a future research agenda.Phthalic acid esters (PAEs) are compounds that are used in the bottle as the main plasticizers. Therefore, the possibility of releasing phthalate esters into beverages is very high and there is a concern to consumer health and monitoring organizations. The aim of this research was to assess the phthalic acid esters (di-n-octyl phthalate (DNOP), butyl benzyl phthalate (BBP), dimethyl phthalate (DMP), diethyl phthalate (DEP) and dibutyl phthalate (DBP), bis(di-ethylhexyl) phthalate (DEHP), and total PAEs) in bottled non-alcoholic malt beverages (n = 120) by multi-walled carbon nanotubes were magnetized with iron (MWCNT-Fe3O4) using gaschromatography/mass spectrometry (GC-MS). The results showed that the highest and the lowest levels of total phthalate esters in samples were 9483.93 and 2412.50 ng/L, respectively. The mean of DEHP which has also been found to be carcinogenic in all samples was lower than 5944.73 ng/L. The highest concentration of DEHP in four samples was upper than 8957.87 ng/L. Perceived limit of detection (LOD) ranged from 13 to 30 ng/L and the limit of quantification (LOQ) ranged from 39 to 90 ng/L. Multivariate techniques and heat map visualization were used to assess the correlation among the type and levels of PAEs with the brand, color, product date, pH, sugar, volume, and gas pressure. Therefore, based on heat map and principal component analysis (PCA) results, the DEHP and total PAEs were the closest accessions, indicating that these variables had similar trends. Based on the results, it can be stated that due to the low average of total phthalate esters in non-alcoholic malt beverages, there is no serious health hazard of these compounds for humans.Cannabidiol (CBD) is a non-psychotomimetic compound with strong potential to decrease the psychostimulant's rewarding effect with unclear receptors. Furthermore, as a part of the reward circuit, the hippocampus plays a crucial role in regulating the reward properties of drugs as determined by conditioned place preference (CPP). In the current research, CPP was used to evaluate the role of intra-CA1 microinjection of D1-like dopamine receptor antagonists in CBD's inhibitory effect on the acquisition and expression phases of methamphetamine (METH). Animals were treated by METH (1 mg/kg; sc) in a five-day schedule to induce CPP. To find out the impact of D1-like dopamine receptor antagonist, SCH23390, in the CA1 on the inhibitory influence of CBD on the acquisition of METH, the rats received intra-CA1 administration of SCH23390 (0.25, 1, and 4 µg/0.5 µl) following ICV treatment of CBD (10 µg/5 µl) over conditioning phase of METH. Furthermore, animals were given SCH23390 in the CA1 ensuing ICV microinjection of CBD (50 µg/5 µl) in the expression phase of METH to rule out the influence of SCH23390 on the suppressive effect of CBD on the expression of METH CPP.
