    Abstract Objectives: To explore associations between PCDS, incident dementia and mortality risk and evaluate the potential of its reversibility.
    Methods: 963 participants from the I-Lan Longitudinal Aging Study were followed up for 6 years for analysis. A subsample of 513 participants was invited to participate 3 years earlier. The 1.5 standard deviation lower age- and education-matched norms of neuropsychiatric assessments determined cognitive impairment. Weakness and slowness were defined by the Asian Working Group for Sarcopenia 2019. PCDS was defined as cognitive impairment plus mobility impairment, i.e., weakness and/or slowness.
    Results: The prevalence of PCDS was 19.0% among 1709 participants aged 63.5 ± 9.0 years (from 50 to 90 years) and increased with age (14.7% in people aged 50-64 years, 19.5% in people aged 65-74 years, 36.7% in people aged 75-84 years and 45.5% in people aged ≥ 85 years, p for trend <0.001). 13.6% and 8.3% of participants had improved PCDS conditions in 513 participants at 3-year and in 963 participants at 6-year assessments. Of 118 participants with PCDS at baseline,36 (30.5%) returned to non-PCDS in 6 years. Being female and having good nutrition were potential associated factors. During the mean follow-up period of 5.9 ± 0.9 years, 182 deaths occurred in the 10,065 person-years. PCDS could predict the 6-year risk of mortality (HR 1.56, 95% CI 1.02-2.39, p = 0.012) and 6-year incident dementia (OR 3.42, 95% CI: 1.41-8.29, p = 0.007).
    Conclusions: PCDS significantly predict 6-year mortality and 6-year incident dementia. Reversibility of PCDS made it as an optimal target for intervention and prevention.

    Abstract Lan-Bai Metropolitan Area in Gansu province is an important heavy-industry base with the highest level of total air pollutant emissions in Northwest China. It is significant to study the high-resolution pollutant emission inventory to forecast regional air quality and to simulate pollutant emission reduction, as well as provide early warnings and forecasts, and to control air pollution. Taking Lanzhou and Baiyin as the main research areas, this study established the gridded emission inventories of seven major criteria air pollutants in the Lan-Bai Metropolitan Area based on emission data and statistical yearbooks of 2015-2016. The spatial pollution characteristics and emission source contributions were also studied. The results showed that the total annual emissions of seven major criteria air pollutants in the Lan-Bai Metropolitan Area were as followings:NO

    Abstract Traditional Chinese medicine (TCM) belongs to the most elaborate and extensive systems of plant-based healing. The herb Northern Ban Lan (Isatis tinctoria) is famous for its antiviral and anti-inflammatory activity. Although numerous components isolated from I. tinctoria have been characterized so far, their modes of action have remained unclear. Here, we show that extracts from I. tinctoria exert anti-microtubular activity. Using time-lapse microscopy in living tobacco BY-2 (Nicotiana tabacum L. cv Bright Yellow 2) cells expressing green fluorescent protein-tubulin, we use activity-guided fractionation to screen out the biologically active compounds of I. tinctoria. Among 54 fractions obtained from either leaves or roots of I. tinctoria by methanol (MeOH/H

    Abstract Understanding dynamic changes in the genetic architecture of quantitative traits is crucial in developmental genetics. Functional mapping is an appropriate method that passes a mathematical equation to describe a biological developmental process with the genetic mapping framework. Appropriate genetic model and applicable mapping population are indispensable condition for functional mapping of important agronomic traits in plants. Based on the Wang-Lan-Ding model, we ever applied a DH population to carry out functional mapping QTLs underlying growth trajectory on tiller number. However, inconsistent genetic background among the DH lines might disturb the mapping results. With the advent of innovative research materials, single segment substitution lines, allows us to do more precise genetic analyses. Thus functional mapping was again conducted on tiller number using the Wang-Lan-Ding model and a single segment substitution line population with the genetic background of Huajingxian 74 so as to explore QTL dynamic mechanism to regulate developmental traits. We detected that all five single segment substitution lines harbored tillering QTLs with additives and/or dominances to influence the four functional parameters, the optimum tillering time (t

    Abstract Understanding dynamic changes in the genetic architecture of quantitative traits is crucial in developmental genetics. Functional mapping is an appropriate method that passes a mathematical equation to describe a biological developmental process with the genetic mapping framework. Appropriate genetic model and applicable mapping population are indispensable condition for functional mapping of important agronomic traits in plants. Based on the WangLan–Ding model, we ever applied a DH population to carry out functional mapping QTLs underlying growth trajectory on tiller number. However, inconsistent genetic background among the DH lines might disturb the mapping results. With the advent of innovative research materials, single segment substitution lines, allows us to do more precise genetic analyses. Thus functional mapping was again conducted on tiller number using the WangLan–Ding model and a single segment substitution line population with the genetic background of Huajingxian 74 so as to explore QTL dynamic mechanism to regulate developmental traits. We detected that all five single segment substitution lines harbored tillering QTLs with additives and/or dominances to influence the four functional parameters, the optimum tillering time (t₀), the maximum tiller number (K), the tillering increased rate (r) and the tillering decreased rate (c), which were estimated from the WangLan–Ding model and with some biological meaning. They mainly brought the inflexion point (t₀) delay, the peak increase (K) and the degradation (c) acceleration, while the growth (r) slow down. Moreover, epistatic interactions among these QTLs were confirmed to be prevalent. A total of 39 significant epistatic effects were detected to associate with the four parameters, occupying 34.8% of 112 pairs of epistatic interactions investigated. Contrary to the QTL effects, these epistatic effects largely decreased t₀, K and c, while increased r. Our results indicated that the five QTL effects and their epistatic effects significantly changed the shape and trajectory of tiller number via influence of the four functional parameters. Rational use of these QTLs is expected to improve tillering number of rice by molecular design breeding.

    Abstract Traditional Chinese medicine (TCM) belongs to the most elaborate and extensive systems of plant‐based healing. The herb Northern Ban Lan (Isatis tinctoria) is famous for its antiviral and anti‐inflammatory activity. Although numerous components isolated from I. tinctoria have been characterized so far, their modes of action have remained unclear. Here, we show that extracts from I. tinctoria exert anti‐microtubular activity. Using time‐lapse microscopy in living tobacco BY‐2 (Nicotiana tabacum L. cv Bright Yellow 2) cells expressing green fluorescent protein‐tubulin, we use activity‐guided fractionation to screen out the biologically active compounds of I. tinctoria. Among 54 fractions obtained from either leaves or roots of I. tinctoria by methanol (MeOH/H₂O 8:2), or ethyl acetate extraction, one specific methanolic root fraction was selected, because it efficiently and rapidly eliminated microtubules. By combination of further purification with ultra‐high‐performance liquid chromatography and high‐resolution tandem mass spectrometry most of the bioactivity could be assigned to the glucosinolate compound glucobrassicin. Glucobrassicin can also affect microtubules and induce apoptosis in HeLa cells. In the light of these findings, the antiviral activity of Northern Ban Lan is discussed in the context of microtubules being hijacked by many viral pathogens for cell‐to‐cell spread.

    Abstract Background: To evaluate the predictive validity of sarcopenia defined by the Foundation for the National Institutes of Health (FNIH) Sarcopenia Project among Asian older adults.
    Methods: Data of the I-Lan Longitudinal Aging Study were obtained for analysis. Overall, 1,839 community-dwelling people aged 50 years and older, capable of completing a 6-m walk, with life expectancy of more than 6 months, and not institutionalized at time of data collection were enrolled for study. Data for subjects aged 65 years and older were obtained for study. The outcome measures were all-cause mortality and a composite adverse outcome which includes hospitalizations, emergency department visits, institutionalization, and falls.
    Results: Data of 728 eligible elderly participants (73.4 ± 5.4 years; 52.9% males) were analyzed. The prevalence of FNIH-diagnosed sarcopenia was 9.5%: 11.9% males; 6.7% females. Participants having FNIH-defined sarcopenia were considerably older, frailer, more obese, with poorer physical performance than nonsarcopenic subjects (All p < .001); during mean follow-up of 32.9 ± 8.8 months, they also had 3.8 times higher risk of dying, independent of age, sex, multimorbidity, cognitive function, and nutritional status (hazard ratio = 3.8; 95% confidence interval = 1.26-11.45; p = .018). Moreover, sarcopenia defined by grip strength-BMI ratio (WeakBMI) showed stronger association with composite adverse outcomes than traditional handgrip strength (hazard ratio = 1.99; 95% confidence interval = 1.01-3.93; p = .047 vs hazard ratio = 1.80; 95% confidence interval = 0.89-3.62; p = .102 in fully-adjusted model).
    Conclusion: Among community-dwelling older people in Taiwan, participants with FNIH-defined sarcopenia had a significantly greater risk of all-cause mortality and composite falls, emergency department visits, institutionalization, and hospitalization.
