Abstract
Goose is an important type of domesticated poultry. The wild geese that are regarded as the ancestors of modern domestic geese present gray plumage. Domesticated, geese have both white and gray feathers. To elucidate the genetic mechanisms underlying the formation of white and gray plumage in geese, we resequenced the whole genome of 18 geese from six populations including white and gray goose breeds. The average sequencing depth per individual was 9.81× and the average genome coverage was 96.8%. A total of 346 genes were detected in the top 1% of FST scores of gray- and white-feathered geese, and a significant FST site was located in the intron region within the KIT gene, the 18 bp deletion in KIT having the strongest potential association with white feathers. It has been reported that a number of genes are associated with plumage colors in birds. However, no studies have identified the relationship between KIT and plumage color in birds at present, although the white coat can be attributed to mutations in KIT in some mammals. Our study showed that that KIT is a plausible candidate gene for white/gray plumage color in Chinese domestic geese.

Abstract
If a radiation source is lost, it will do harm to human being, especially for the searching person. In order to find the lost radiation source easily, a detector system, including 3 detectors, was designed to search the lost c-ray radiation source autonomously in any environment. First, based on GEANT4 simulation, the radiation dose rates in 3 Geiger Muller (GM) counters were simulated at the different source-detector distances, distances between detectors and angles. Various analyses were performed by experimentally and verified the simulated detector designed system. A Mono-energetic 137Cs c-ray source with energy 662 keV and activity of 1.11 GBq was used for the observation. The simulated results were compared with the experimental dose rate values and obtained good agreements for various cases. Only based on the dose rates in three detectors, the radiation source was searched in a different location at a specific source activity and angle. The corresponding angles of deviation and detection limit were calculated for sensitivity and ability of detector designed system. The proposed detector designed system can be used to navigate radiation sources in the low level and high radiation environments.

Abstract
Due to progressive population aging, a new dementia case occurs at every 3 seconds, placing a heavy burden of disease. Identifying potential risk or preventive factors is emphasized owing to a lack of effective treatment for dementia. There has been emerging evidence on the link of certain dietary components, particularly polyphenols, to brain wellness and cognitive outcomes. Findings from animal and in vitro studies appear more consistent and conclusive. However, such an association has not been investigated in depth in human beings. In this review, we examined studies on the effect of dietary polyphenols (including flavonoids, curcumin, and resveratrol) on cognitive function. Intervention in early stages of dementia/Alzheimer's disease might be a target to slow down age-related cognitive decline before disease onset. We summarized 28 epidemiological studies (8 cross-sectional and 20 cohort studies) and 55 trials in this review. Preliminary evidence from epidemiological data provides the necessity for intervention trials, even though the measures of polyphenol intake tend to be less precise. Clinical trials are in favor of the role of some polyphenols in benefiting specific domains of cognition. This review also describes the divergence of results and current limitations of research in this field.

Abstract
The use of precision technology is increasingly seen as an option to improve productivity, animal welfare, resource use efficiency, and workplace features on dairy farms. There is limited research related to longitudinal adoption patterns of precision dairy technologies and reasons for any patterns. The aim of this analysis was to investigate trends in technology adoption regarding both the amount (number of farms with a technology) and intensity (number of technologies per farm) of adoption. Surveys of parlor technology adoption were conducted on New Zealand dairy farms in 2008, 2013, and 2018, with 532, 500, and 500 respondents, respectively. Technologies were grouped into labor-saving (LS, such as automatic cluster removers) or data-capture (DC, such as in-line milk meters) categories. Trends were examined for farms that had only LS, only DC, or LS+DC technologies. Technology adoption increased over time; the likelihood of technology adoption in 2018 (and 2013 in parentheses) increased by 21 (22), 7 (68), and 378% (165) for LS, DC, and LS+DC technology groups, respectively, compared to 2008. Farms with LS+DC technologies also had a greater proportion of LS technologies compared to non-LS+DC farms, although this relationship declined over the 10-yr period. The use of a rotary versus herringbone parlor was estimated to be associated with 356 and 470% increase in the likelihood of adopting LS technologies and LS+DC, respectively, from 2008 to 2018. Regional differences in adoption were also found, with the likelihood of adopting DC and LS+DC technologies found to be 46 and 59% greater, respectively, in the South Island of New Zealand, compared to the base region of Waikato. The results highlight the importance of understanding spatial and temporal farm characteristics when considering future effect and adoption of precision dairy technologies. For example, the analysis indicates the occurrence of 2 trajectories to technology investment on farms, where larger farms are able to take advantage of technology opportunities, but smaller farms may be constrained by factors such as lack of economies of scale, limited capital to invest, and inability to retrofit technology into aging parlor infrastructure.

Abstract
Abstract
Background
Atrial fibrillation (AF) often coexists with coronary artery disease. Data on the incidence and prognostic impact of new-onset AF following acute myocardial infarction (AMI) with current optimal therapy are insufficient, especially in Asian populations.
Purpose
To investigate the incidence of new-onset AF following AMI and to assess its impact on in-hospital and long-term prognosis.
Methods
We included consecutive AMI patients between December 2012 and July 2019, and excluded those with prior known AF on presentation. New-onset AF was defined as newly detected AF during the index hospitalization following AMI. The primary outcomes comprised of all-cause death and cardiovascular death occurred during hospitalization; and all-cause death and cardiovascular death during long-term follow-up among those AMI survivors. Follow-up visits were routinely scheduled after discharge, at 1 month, 3 months, 6 months, 12 months and every 12 months thereafter.
Results
Of 3686 patients enrolled, new-onset AF was documented in 138 (3.7%) patients during a mean duration of hospitalization of 8.8±5.8 days. Independent risk factors of new-onset AF were age ≥75 years, left atrial diameter ≥40mm, high levels of cardiac troponin-I or high sensitive C reactive protein. During hospitalization, all-cause death occurred in 22 (15.9%) new-onset AF patients and 67 (1.9%) non-AF patients (p<0.001); cardiovascular death occurred in 19 (13.8%) new-onset AF patients and 58 (1.6%) non-AF patients (p<0.001). On multivariable logistic analysis, new-onset AF was an independent predictor of in-hospital all-cause death (OR 5.85, 95% CI: 3.24–10.55) and cardiovascular death (OR 5.44, 95% CI: 2.90–10.20). Apart from the in-hospital deaths, another 265 (7.7%) were lost to follow-up; thus, 3332 patients were included in the long-term follow-up analysis: 106 new-onset AF and 3226 non-AF patients. After a mean follow-up period of 1096.7±682.0 days, all-cause death occurred in 19 new-onset AF patients and 249 non-AF patients; corresponding rates were 8.08 (95% CI: 5.15–12.67) vs. 2.55 (95% CI: 2.25, 2.88) per 100 person-years, respectively (p<0.001). Cardiovascular death occurred in 11 new-onset AF patients and 150 non-AF patients; corresponding rates were 4.68 (95% CI: 2.59–8.45) vs. 1.53 (95% CI: 1.31–1.80) per 100 person-years, respectively (p=0.002). After multivariable Cox adjustment, there was no significant association between new-onset AF and long-term all-cause death (HR 1.45, 95% CI: 0.90–2.35) or cardiovascular death (HR 1.21, 95% CI: 0.65–2.26).
Conclusion
New-onset AF following AMI was an independent predictor of increased risk of in-hospital mortality, but had no independent association with long-term death.

Abstract
Abstract
Background
Mesenchymal stem/stromal cells (MSCs) render potential therapies for multiple ischemic diseases. However, in vitro expansion of MSCs before application leads to a metabolic switch from glycolysis to oxidative phosphorylation, drastically impairing their proliferative and therapeutic capacities.
Purpose
Here we aim to identify the role of SIRT5, a master metabolic regulator, in culture expansion of adipose-derived MSCs (ADMSCs).
Methods
SIRT5 deficiencyADMSCs was obtained from Sirt5−/− mice and their metabolic pattern and proliferation capacity were tested during in vitro expansion. Hind limb ischemic model was established to evaluated the therapeutic function of Sirt5−/−ADMSCs.
Results
SIRT5 protein level was upregulated in ADMCSs undergoing culture expansion. Sirt5−/−ADMSCs during in vitro expansion exhibited higher proliferation rate, delayed senescence and enhanced antioxidant capacity. SIRT5 deficiency induced hypersuccinylation of metabolic-related proteins, leading to attenuated mitochondrial respiration with elevated glycolysis and pentose phosphate pathway. Furthermore, lowering succinylation level by glycine treatment reversed the altered metabolism and enhanced proliferation of Sirt5−/−ADMSCs. In mice hind limb ischemic model, SIRT5−/−ADMSCs treatment achieved better blood flow recovery and angiogenesis compared to WT ADMSCs treatment.
Conclusion
We reveal that SIRT5 is a key regulator of ADMSCs undergoing in vitro culture. Ablation of SIRT5 leads to reversed metabolic pattern, enhanced proliferative capacity and improved therapeutic outcomes. Our data provide a potential target for enhancing MSC functional properties during bio-manufacturing in future MSC therapy. Such work may not only benefit MSC cell therapy, but could extent to a wide variety of other stem cells that share similar metabolic pattern.

Abstract
We report the observation of an intriguing behavior in the transport properties of nanodevices operating in a regime between the Fabry-Pérot and the Kondo limits. Using ultrahigh quality nanotube devices, we study how the conductance oscillates when sweeping the gate voltage. Surprisingly, we observe a fourfold enhancement of the oscillation period upon decreasing temperature, signaling a crossover from single-electron tunneling to Fabry-Pérot interference. These results suggest that the Fabry-Pérot interference occurs in a regime where electrons are correlated. The link between the measured correlated Fabry-Pérot oscillations and the SU(4) Kondo effect is discussed.

Abstract
Egg-type ducks and meat-type ducks are predominantly commercial or indigenous and have been subjected to artificial directional selection. These two duck types differ substantially in body shape, production performance and reproductivity. However, the genetic changes associated with phenotypic differences remain unclear. Here, we compared the two duck types at the genomic and transcriptomic levels. We identified a large number of SNPs and genes in genomic divergent regions in terms of FST and θπ values. The corresponding genes were mainly enriched in embryonic development function and metabolic pathway. RNA-seq analysis also revealed differential gene expression in the liver and gonads. The differentially expressed genes were functionally associated with signal transmission and substance metabolism respectively. Furthermore, we found that seven genes were related to differentiation between the two types by both g genome and transcriptome analysis and were plausible candidate genes. These genes were annotated to GO categories of cell development and disease immunity. These findings will enable a better understanding of the artificial selection history of meat and egg ducks and provide a valuable resource for future research on the breeding of these two lineages.

Abstract
Microbial diversity of pit mud (PM) plays a significant role in Baijiu's flavour. Here we explored the microbial community structures and aroma substances of Wenwang Winery with high-throughput sequencing coupling with headspace solid-phase microextraction-gas chromatography-mass spectrometry. We discovered that the odorant was mainly derived from 14 aroma compounds because of their OAVs ≥ 1 (OAV, the ratio of substance concentration to aroma threshold; s, on behalf of the plural), such as ethyl hexanoate (2438), ethyl octanoate (975), caproic acid (52) and etc. Moreover we also revealed that Lactobacillaceae (97·08%) was the mainly bacterial microbial community in 2-year-old PM, companied by the primarily fungi including Aspergillaceae (55·45%), Unclassified Ascomycota (11·13%) and Dipodascaceae (5·72%). Compared with the 2-year-old PM, bacterial floras in 20-year-old PM and 30-year-old PM were more abundant (i.e. Dysgonomonadaceae, Clostridium and Synerggstaceas), while no fungi were detected. Besides, the physicochemical analysis showed that the content of Lactobacillaceae was inversely associated with moisture, pH and ammonia nitrogen. By further Spearman's correlation coefficient analysis, we verified that the content of Lactobacillaceae was positively correlated with ethyl hexanoate, while negatively correlated with ethyl octanoate and caproic acid. Meanwhile, ethyl octanoate and caproic acid were positively correlated with most flora including Ruminococcaceae, Dysgonomonadaceae and Clostridiacea, which were related to physicochemical indexes. This work demonstrates promise for adjusting the physicochemical indexes of PM to affect the micro-organisms and aroma, which may provide a reference for the production of high-quality Baijiu.

Abstract
The purpose of this study was to identify risk factors for falls in postmenopausal women and provide evidence for the primary prevention of falls in postmenopausal women. The protocol for this meta-analysis is registered with PROSPERO (CRD42020170927). We searched PubMed, the Cochrane Library and EMBASE for observational studies on the risk factors for falls in postmenopausal women. Review Manager 5.3 was used to calculate the relative risk (RR) or weighted mean difference (WMD) of potential risk factors related to falls. STATA 14.0 was used for the quantitative evaluation of publication bias. Eleven studies with 42,429 patients from 7 countries were included. The main risk factors for falls in postmenopausal women were patient sociodemographic risk factors (age: WMD = 0.37, 95% CI 0.07 to 0.68; body weight: WMD = 0.88, 95% CI 0.56 to 1.12; BMI: WMD = 0.34, 95% CI 0.21 to 0.46; exercise: RR = 0.97, 95% CI 0.94 to 0.99; and FES-I: WMD = 6.60, 95% CI 0.72 to 12.47) and medical risk factors (dietary calcium intake: WMD = - 16.91, 95% CI - 25.80 to - 8.01; previous fracture history: RR = 1.21, 95% CI 1.13 to 1.29; previous falls: RR = 2.02, 95% CI 1.91 to 2.14; number of diseases, ˃ 2: RR = 1.17, 95% CI 1.11 to 1.23; and number of reported chronic health disorders: WMD = 0.30, 95% CI 0.10 to 0.49). Knowledge of the many risk factors associated with falls in postmenopausal women can aid in fall prevention. However, we cannot rule out some additional potential risk factors (age at the onset of menopause, years since last menstruation, hormone therapy and BMD) that need further clinical research.

Abstract
Naringenin is a flavonoid compound with antioxidant effects. It is used to treat oxidative stress-related diseases, but its mechanism is unclear. In this experiment, we explored whether naringenin can increase the expression of superoxide dismutase 1(SOD1), reduce the oxidative stress of PC12 cells induced by homocysteine (Hcy), and decrease the apoptosis of PC12 cells induced by Hcy by inhibiting the expression of mir-224-3p. Different concentrations of Hcy (1, 3, 5, 8, and 10 mmol/L) was used to analyze effect of homocysteine on PC12 cells. A total of 5 mmol/L Hcy was used to induce the excitatory and neurotoxicity model of PC12 cells in vitro. The cells were divided into normal control, Hcy induction, Hcy + Naringenin (25 μM), Hcy + Naringenin (50 μM), Hcy + Naringenin (75 μM), Hcy + Naringenin (100 μM), and Hcy + Naringenin (150 μM) groups. The relative survival rate and activities of the PC12 cells were determined by the MTT method, and the apoptosis rate of the PC12 cells was determined by using flow cytometry. The Western blot method was used to determine the expressions of SOD1, Bax, Caspase-3, Caspase-8, and Bcl-2 in the PC12 cells induced by Hcy. The expressions of SOD1 mRNA and miR-224-3p in the Hcy-induced PC12 cells were determined by RT-PCR. Results found that Hcy increased the expression of miR-224-3p in a dose-dependent manner but decreased that of SOD1 mRNA and protein. Hcy also increased oxidative stress in the PC12 cells and the proapoptotic proteins Bax, Caspase-3, and Caspase-9. Furthermore, it decreased the expression of anti-apoptotic protein Bcl-2 and the activity and survival rate of the HT22 cells, but it increased the apoptosis of the PC12 cells. The treatment of Hcy-induced PC12 cells with different concentrations of naringenin for 24 h decreased the expression of miR-224-3p in a dose-dependent manner and increased the expressions of SOD1 mRNA and protein. The treatment also decreased the oxidative stress in the PC12 cells and the expressions of pro-apoptotic proteins Bax, Caspase-3, and Caspase-9; increased the expression of anti-apoptotic protein Bcl- 2; decreased the apoptosis of the PC12 cells; and increased the PC12 cells.The results suggest that Naringenin can decrease the apoptosis and oxidative stress of PC12 cells induced by Hcy and increase the activities and survival rates of PC12 cells. The mechanism may be related to naringenin decreasing the expression of miR-224-3p in PC12 cells induced by Hcy and increasing the expressions of SOD1 mRNA and protein.
