Abstract
Advanced age is an independent risk factor for coronary artery disease (CAD), the leading global cause of mortality. Senescent vascular cells in the atherosclerotic plaques exhibit senescence-associated secretory phenotype (SASP). How SASP contributes to atherosclerosis and CAD, however, remains unclear. Here, we integrated RNA-array datasets of senescent human coronary arterial endothelial cells (HCAECs) and aortic smooth muscle cells (HASMCs) as well as genome-wide association data for CAD. We identified 26 genes from HCAECs and 6 genes from HASMCs related to SASP and CAD in both in-house and published datasets. Of which, Cystatin C (CST3), a CAD susceptibility gene, was found to be expressed in both HCAECs and HASMCs, thus, it was prioritized for further investigation. We demonstrated it was significantly elevated in senescent vascular cells, aged arteries, and early atherosclerosis. In vitro experiments showed that CST3 enhances the monocyte-endothelial cell adhesion. Additionally, ligand-receptor pairing analyses revealed two important pathways, COL4A1-ITGA1 and LPL-LRP1 pathways, linked to the critical processes in the development of atherosclerosis, including cell adhesion, inflammation response, extracellular matrix organization, and lipid metabolism. We further demonstrated a reduced monocyte-endothelial cell adhesion following the knockdown of COL4A1 or ITGA1 and a significantly increased expression of COL4A1, ITGA1, and LPL in arterial intima of aged mice and ApoE-/- mice. Our findings demonstrate that vascular cell-derived SASP proteins increase the CAD susceptibility and identify CST3 functionally contributing to atherosclerosis.

Abstract
Objective: To investigate the prevalence and Influence factors of work-related musculoskeletal disorders (WMSDs) among dental nurses in tertiary stomatology hospitals. Methods: From June to July 2020, 1321 dental nurses from 18 tertiary stomatology hospitals in 18 provinces of China were enrolled as research subjects through a phased sampling method. The cross-sectional study was performed with validated instruments including the basic information questionnaire, Effort-Reward Imbalance Questionnaire, Nurse-Physician Collaboration Scale, and Chinese Musculoskeletal Questionnaire, so as to get the information about the social demography information, nursing-physician cooperation, work stress and the incidence of WMSDs. The influenang factors of WMSDs was analyzed. Results: The past prevalence, annual prevalence, and weekly prevalence of WMSDs were 80.8% (1067/1321) , 68.7% and 43.7% (575/1321) . 58.4% (771/1321) of nurses had WMSDs in three or more body parts. Neck (51.4%) , waist (42.2%) and shoulder (41.6%) were the top three body regions in the past year. The absenteeism rate due to musculoskeletal disorders ranged from 3.5% to 9.0%, waist (8.9%) and neck (8.0%) were the top two body regions. Working more than 40 hours per week (OR=1.74, P<0.001) and effect/reward>1 (OR=1.50, P=0.002) were risk factors of WMSDs (OR=1.74, 95% CI: 1.32~2.30; OR=1.50, 95%CI: 1.17~1.92, P<0.05) , while regular physical exercise every week (≥30 min per times) was the protective factor (OR=0.74, 95%CI: 0.56~0.97, P=0.030) . Conclusion: The prevalence rate of WMSDs of dental nurses in China was high, and most of the nurses suffered with many body parts. Thus, we should reduce controllable occupational stresso, ensuring adequate rest and strengthening physical exercise to reduce the incidence of WMSDs.

Abstract
Our ability to predict how temperature modifies phenology at the community scale is limited by our lack of understanding of responses by functional groups of flowering plants. These responses differ among species with different life histories. We performed a reciprocal transplant experiment along four elevation gradients (e.g., 3,200, 3,400, 3,600 and 3,800 m) to investigate the effects of warming (transferred downward) and cooling (transferred upward) on plant flowering functional groups (FFGs) and community phenological sequences (i.e., seven phenological events). Warming significantly decreased early-spring-flowering (ESF) plant coverage and increased mid-summer-flowering plant (MSF) coverage, while cooling had the opposite effect. All community phenological events were advanced by warming and delayed by cooling except for the date of complete leaf-coloring, which showed the opposite response. Warming and cooling could cause greater advance or delay in early-season phenological events of the community through increased coverage of MSF species, and warming could delay late-season phenological events of the community by increased coverage of ESF species. These results suggested that coverage change of FFGs in the community induced by temperature change could mediate the responses of the community phenological events to temperature change in the future. The response of phenological events to temperature change at the species level may not be sufficient to predict phenological responses at the community-level due to phenological compensation between species in the community.

Abstract
The Cheddar cheese colorant annatto is present in whey and must be removed by bleaching. Chemical bleaching negatively affects the flavor of dried whey ingredients, which has established a need for a better understanding of the primary colorant in annatto, norbixin, along with cheese color alternatives. The objective of this study was to determine norbixin partitioning in cheese and whey from full-fat and fat-free Cheddar cheese and to determine the viability of bixin, the nonpolar form of norbixin, as an alternative Cheddar cheese colorant. Full-fat and fat-free Cheddar cheeses and wheys were manufactured from colored pasteurized milk. Three norbixin (4% wt/vol) levels (7.5, 15, and 30 mL of annatto/454 kg of milk) were used for full-fat Cheddar cheese manufacture, and 1 norbixin level was evaluated in fat-free Cheddar cheese (15 mL of annatto/454 kg of milk). For bixin incorporation, pasteurized whole milk was cooled to 55 °C, and then 60 mL of bixin/454 kg of milk (3.8% wt/vol bixin) was added and the milk homogenized (single stage, 8 MPa). Milk with no colorant and milk with norbixin at 15 mL/454 kg of milk were processed analogously as controls. No difference was found between the norbixin partition levels of full-fat and fat-free cheese and whey (cheese mean: 79%, whey: 11.2%). In contrast to norbixin recovery (9.3% in whey, 80% in cheese), 1.3% of added bixin to cheese milk was recovered in the homogenized, unseparated cheese whey, concurrent with higher recoveries of bixin in cheese (94.5%). These results indicate that fat content has no effect on norbixin binding or entrapment in Cheddar cheese and that bixin may be a viable alternative colorant to norbixin in the dairy industry.

Abstract
The seeds of Fritillaria cirrhosa contain immature embryos at harvest. To afterripen the embryos, different temperatures are required at different stages. Experiments show that 15 degrees C is the most suitable temperature for the earlier stage of morphological development of the embryos, and 10 degrees C for the later stage. To release from the physiological dormancy, chilling at 5 degrees C for 73-91 days is desirable.
