Despite research on shantytown redevelopment highlighting socio‐spatial exclusion, the viewpoint frequently disseminated through social media depicts it as a massive wealth‐creation movement in China. This paper intends to provide evidence that evicted residents of a shantytown in Nanjing, China, share a common identity with the encroaching gentrifiers – the housing class. By shaping the housing class, an increasing number of urban residents become micro‐agents of housing financialization, allowing the rent gap to be frequently opened even without producing a 'higher and better' space. This enables capital to circulate and accumulate within a broader temporal and spatial scope. However, both the class imagination of the housing class and the financial speculation in the housing market are based on the expectation of continuous price growth. This is unsustainable and leaves the real housing needs out of the housing market, which is detrimental to housing equity. [ABSTRACT FROM AUTHOR]

Background: Transseptal puncture (TSP) is a crucial technique for catheter ablation of atrial fibrillation (AF). Although intracardiac echo (ICE) facilitates a safe and accurate TSP, it is not widely used in developing countries because of the expense. This study evaluated the efficiency and safety of a novel cardiac multidetector computed tomography (MDCT)‐guided TSP during AF catheter ablation. Methods: The study consisted of two cohorts. In the index cohort, TSP procedure was performed under the guidance of ICE, and we recorded the angulation of right anterior oblique of X‐ray projection. In the validation cohort, we compared the efficiency and safety of TSP guided by MDCT‐calculated angulation with propensity‐score‐matched patients who underwent TSP guided by ICE. Results: We included 50 patients in the index cohort, and the mean angles of interatrial septum (IAS) measured from MDCT and ICE were 34.8 ± 6.3 and 35.1 ± 6.5, respectively. In the validation cohort, 376 patients were enrolled in the MDCT‐guided group and ICE‐guided group. Both groups had 1 case of cardiac tamponade. The mean axial plane angle was 35.46 ± 6.17 degrees, which was not influenced by age, gender, BMI, and LA size, while a moderate positive linear correlation between EF and the axial plane angle (R2 = 0.14, p =.006). Conclusion: Cardiac MDCT can provide a clear vision of IAS orientation, and provide the appropriate RAO angle and height for TSP. The efficiency and safety of our MDCT‐guided TSP were comparable to ICE‐guided TSP, which may serve as an alternative method for TSP with ICE unavailable. [ABSTRACT FROM AUTHOR]

Background: Erectile dysfunction is a condition with a high incidence among adult men. Lycopene has been shown to lower blood glucose and reduce weight in diabetic patients because of its antioxidant and anti‐inflammatory properties. However, the association between lycopene and the incidence of erectile dysfunction is unclear. Objective: The aim of this study was to examine the dietary lycopene intake and its association with erectile dysfunction risk in the US population. Materials and methods: We investigated the lycopene intake of adult participants with complete information on clinical variables from the National Health and Nutrition Examination Survey between 2001 and 2004. Dose–response curve analysis was applied to explore the association between lycopene intake and erectile dysfunction. Logistic regression models were used to adjust for confounders. Different ethnicities, body mass index level, hypertension status, diabetes status, and smoking status were analyzed as subgroups. Propensity score matching was employed to eliminate the effects of potential confounders to confirm the reliability of the results. Results: A total of 3265 participants with lycopene consumption data were included in our study, including 931 individuals with erectile dysfunction and 2334 without erectile dysfunction during National Health and Nutrition Examination Survey 2001–2004. We found more consumption of lycopene in the non‐erectile dysfunction group than in the erectile dysfunction group. Dose–response curve analysis revealed a significant negative association between lycopene intake and erectile dysfunction prevalence. After adjusting for age, race, cigarette smoking, body mass index, annual family income, education, physical activity, hypertension, diabetes, depression, and testosterone level, we found that increased lycopene intake reduced the odds ratio of erectile dysfunction. Low lycopene intake was positively related to erectile dysfunction in almost all subgroups, especially in Mexican American, non‐Hispanic white, body mass index <25, hypertension positive, diabetes mellitus negative, and smoke negative. Furthermore, the results were confirmed in the 1:1 matched group. Conclusion: Our national data suggest that lower dietary lycopene intake is positively associated with an increased risk of erectile dysfunction in US men. [ABSTRACT FROM AUTHOR]

Microbial necromass, an important and stable source of soil organic carbon (SOC), is an important index to evaluate the contribution of microorganisms to SOC transformation and accumulation. It is not clear about the accumulation of microbial necromass in deep soil layer and its contribution to SOC during the restoration process of Caragana korshinskii forests. Combined with the biomarker method, we investigated the carbon contents of bacterial, fungal, and microbial necromass in the soil profiles (0-100 cm) of C. korshinskii forests in 16, 28, and 38 years of restoration, with natural grassland as control. We further examined the contribution of microbial necromass to soil organic carbon. The results showed that: 1) Along the soil profile (0-100 cm), the contents of fungal neccrease in FNC/SOC, BNC/SOC, and MNC/SOC in the soil of C. korshinskii forests in 38 years of restoration, FNC/SOC and MNC/SOC generally showed an increasing trend followed by a decreasing trend in other plots, while BNC/SOC gradually decreased. 2) With the increases of restoration years, the contents of FNC, BNC, and MNC significantly decreased in C. korshinskii forests. FNC/SOC and MNC/SOC showed an overall increasing trend followed by a decreasing trend, while BNC/SOC gradually decreased. 3) The average contribution of microbial necromass carbon to SOC was highest in C. korshinskii forests in 28 years of restoration (35.0%), followed by C. korshinskii forests in 16 years of restoration (33.5%), natural grassland (31.0%), and C. korshinskii forests in 38 years of restoration (28.6%). In conclusion, when the restoration years of C. korshinskii forests are 16, the contents of microbial necromass carbon and their contributions to SOC are higher compared to natural grassland, which are beneficial for SOC sequestration.

In order to study the change rule of free radicals in the process of continuous oxygen consumption of coal, four kinds of bituminous coals with different degrees of deterioration were selected and electron paramagnetic resonance apparatus was used to study the change rule of free radicals in the process of continuous oxygen consumption of different bituminous coals from oxygen-rich to oxygen-poor under the condition of variable temperatures. The experimental results show that the species and concentration of free radicals decrease and the symmetry of free radicals increases with the increase of coal metamorphism at room temperature; with the decrease of coal particle size, the concentration of free radical in coal increases, the type remains the same, and the symmetry fluctuates; particle size distribution has great influence on free radicals, concentration, type and symmetry of coal; when the temperature keeps increasing and the oxygen supply keeps decreasing, the concentration of free radicals in coal increases and decreases, while the type and symmetry of free radicals decrease. The continuous oxygen consumption of different types of coal varies with temperature.
