    Publication Date: 2023-01-13
    Description: Plant functional traits provide information about adaptations to climate and environmental conditions, and can be used to explore the existence of alternative plant strategies within ecosystems. Trait data are also increasingly being used to provide parameter estimates for vegetation models. Here we present a new database of plant functional traits from China. Most global climate and vegetation types can be found in China, and thus the database is relevant for global modelling. The China Plant Trait Database contains information on morphometric, physical, chemical and photosynthetic traits from 122 sites spanning the range from boreal to tropical, and from deserts and steppes through woodlands and forests, including montane vegetation. Data collection at each site was based either on sampling the dominant species or on a stratified sampling of each ecosystem layer. The database contains information on 1215 unique species, though many species have been sampled at multiple sites. The original field identifications have been taxonomically standardized to the Flora of China. Similarly, derived photosynthetic traits, such as electron-transport and carboxylation capacities, were calculated using a standardized method. To facilitate trait-environment analyses, the database also contains detailed climate and vegetation information for each site.

    Notes: Abstract Since the early 1940's, systematic studies on phosphate rock (PR) for agricultural use have been made in China. These covered the following aspects: Mineralogical properties of phosphate rock materials, including svanbergite; Ability of different plants to absorb phosphorus from PR; Effect of soil properties on the availability of PR to plants; Technologies for processing powdered PR. Since these studies are mostly published in Chinese [4, 6, 7, 8, 9, 11, 15, 16, 17, 18], they are virtually unknown to agronomists and soil scientists outside China. The present article is a comprehensive review of the studies on PR for agricultural use carried out in China during the last 50 years. It is shown that because of the easily decomposable properties of certain Chinese PR's, the limited industrial potentialities in present day China (particularly the shortage of sulphuric acid), the large areas of strongly acid red soils in Southern China, the introduction of legume crops in the rotation, and the planting of perennial trees, notably rubber in tropical areas, the direct application of powdered PR for agricultural use appears to be very advisable.

    IJERPH, Vol. 13, Pages 696: Knowledge, Attitude, and Behaviors Related to Eating Out among University Students in China (2016)
    MDPI Publishing
    Details
    Publication Date: 2016-07-13
    Description: In many countries the frequency of eating out has steadily increased over the last few decades, and this behavioris often associated with unhealthy dietary patterns. This study aimed to describe the levels of knowledge, attitude, and behaviors (KAB) related to eating out among university students. A cross-sectional study was conducted in the college town in Chongqing, China with a total of 1634 participants. The mean eating out related KAB scores were: knowledge 11.5 ± 2.9, attitude 17.0 ± 2.8, and behaviors 24.2 ± 4.8 (possible total scores: 20, 24, 40 respectively). As the level of knowledge increased, the percentage of highly satisfactory attitude and behaviors increased. Only 10% of the participants did not eat out for lunch and dinner during weekends in the last month. Gender, ethnicity, mother’s education, monthly boarding expenses, living place during the study, and the frequency of eating out for breakfast were statistically associated with the scores of KAB. In conclusion, Chinese junior students had poor knowledge of and behaviors towards eating out and ate out frequently. Educational interventionsto improve knowledge related eating out are needed in order to promote healthy eating out behaviors among Chinese university students.

    Genomic signatures of adenosquamous carcinoma of the pancreas (PASC) (2017)
    Wiley-Blackwell
    Details
    Publication Date: 2017-07-21
    Description: In pancreatic cancer (PC), adenosquamous carcinoma of the pancreas (PASC) containing both ductal adenocarcinoma and squamous carcinoma in the same tumor represents ~ 4% of the total incidence. To date, the genomic features of this mixed tumor are still unknown. We analyzed genomes of 17 PASCs and 34 ductal adenocarcinomas (PDACs), showing that PASC carried highly enriched TP53 mutations and 3p loss compared to PDAC. Furthermore, we uncovered that adenomatous and squamous components of PASC harbored comparable genomic alterations, suggesting that two cellular components are developed from the same progenitor cancer cells. Our study has updated genomic knowledge for helping to understand mixed cancers of the pancreas.

    FRET ratiometric probes reveal the chiral-sensitive cysteine-dependent H2S production and regulation in living cells (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-04-02
    Description: Hydrogen sulfide (H2S) is an endogenously produced gaseous signalling molecule with multiple biological functions. In order to visualize and quantify the endogenous in situ production of H2S in living cells, here we developed two new sulphide ratiometric probes (SR400 and SR550) based on fluorescence resonance energy transfer (FRET) strategy for live capture of H2S. The FRET-based probes show excellent selectivity toward H2S in a high thiol background under physiological buffer. The probe can be used to in situ visualize cysteine-dependent H2S production in a chiral-sensitive manner in living cells. The ratiometric imaging studies indicated that D-Cys induces more H2S production than that of L-Cys in mitochondria of human embryonic kidney 293 cells (HEK293). The cysteine mimics propargylglycine (PPG) has also been found to inhibit the cysteine-dependent endogenous H2S production in a chiral-sensitive manner in living cells. D-PPG inhibited D-Cys-dependent H2S production more efficiently than L-PPG, while, L-PPG inhibited L-Cys-dependent H2S production more efficiently than D-PPG. Our bioimaging studies support Kimura's discovery of H2S production from D-cysteine in mammalian cells and further highlight the potential of D-cysteine and its derivatives as an alternative strategy for classical H2S-releasing drugs.

    Description: Energies, Vol. 11, Pages 1854: Effects of Asymmetric Gas Distribution on the Instability of a Plane Power-Law Liquid Jet Energies doi: 10.3390/en11071854 Authors: Jin-Peng Guo Yi-Bo Wang Fu-Qiang Bai Fan Zhang Qing Du As a kind of non-Newtonian fluid with special rheological features, the study of the breakup of power-law liquid jets has drawn more interest due to its extensive engineering applications. This paper investigated the effect of gas media confinement and asymmetry on the instability of power-law plane jets by linear instability analysis. The gas asymmetric conditions mainly result from unequal gas media thickness and aerodynamic forces on both sides of a liquid jet. The results show a limited gas space will strengthen the interaction between gas and liquid and destabilize the power-law liquid jet. Power-law fluid is easier to disintegrate into droplets in asymmetric gas medium than that in the symmetric case. The aerodynamic asymmetry destabilizes para-sinuous mode, whereas stabilizes para-varicose mode. For a large Weber number, the aerodynamic asymmetry plays a more significant role on jet instability compared with boundary asymmetry. The para-sinuous mode is always responsible for the jet breakup in the asymmetric gas media. With a larger gas density or higher liquid velocity, the aerodynamic asymmetry could dramatically promote liquid disintegration. Finally, the influence of two asymmetry distributions on the unstable range was analyzed and the critical curves were obtained to distinguish unstable regimes and stable regimes.

    Association of cardiac and renal function with extreme N-terminal fragment Pro-B-type natriuretic peptide levels in elderly patients (2012)
    BioMed Central
    Details
    Publication Date: 2012-07-27
    Description: Background: The data are inconsistent regarding whether extreme N-terminal fragment pro-B-typenatriuretic peptide (NT pro-BNP) levels are associated with impaired renal function.Furthermore, the relationship between extreme NT pro-BNP levels and cardiac and renalfunction in elderly patients has not been reported. The aim of the present study was toexamine a hypothesis that extreme NT pro-BNP levels may be associated with impairedcardiac and renal function in elderly patients. Methods: We retrospectively analyzed the data of demographic, clinical, and echocardiographicfeatures on 152 consecutive elderly patients aged more than 80 years old (average age,83.65 +/- 3.58 years) with NT pro-BNP levels [greater than or equal to] 3000 pg/ml. The participants were divided intotwo categories according to their NT pro-BNP levels: (1) 3000-10000 pgmL and (2) 〉10000pg mL. Results: The number of patients with impaired renal function (P = 0.019) and the mortality (P 〈 0.001)in the period of inpatient was higher in the group with NT pro-BNP 〉 10000 pg mL. Thelevels of serum creatinine and creatine kinase MB (CK-MB) in the group of NT pro-BNP 〉 10000 pg mL were higher than those in the group of NT pro-BNP = 3000-10000pgmL (P = 0.001 and P = 0.023, respectively). Furthermore, no significant difference in thedistribution by NYHA class in different NT pro-BNP levels was observed. Multiple linearregression analyses demonstrated that with NT pro-BNP levels as the dependent variable, NTpro-BNP levels were positively correlated with CK-MB (beta = 0.182, P = 0.024) and creatininelevels (beta = 0.281, P = 0.001). The area under the receiver-operating characteristic (ROC)curve of NT pro-BNP levels and clinical diagnosis of impaired renal function was 0.596 andreached significant difference (95%CI:0.503-0.688, P = 0.044). Conclusion: These data suggest that the extreme elevation of NT pro-BNP levels ([greater than or equal to]3000 pg/ml) is mainlydetermined by impaired renal function in elderly patients above 80 years. Extreme NT pro-BNP levels may be useful for assessing the severity of impaired renal function.
