Kinetochore genes are coordinately up-regulated in human tumors as part of a FoxM1-related cell division program

The key player in directing proper chromosome segregation is the macromolecular kinetochore complex, which mediates DNA–microtubule interactions. Previous studies testing individual kinetochore genes documented examples of their overexpression in tumors relative to normal tissue, leading to proposals that up-regulation of specific kinetochore genes may promote tumor progression. However, kinetochore components do not function in isolation, and previous studies did not comprehensively compare the expression behavior of kinetochore components. Here we analyze the expression behavior of the full range of human kinetochore components in diverse published expression compendia, including normal tissues and tumor samples. Our results demonstrate that kinetochore genes are rarely overexpressed individually. Instead, we find that core kinetochore genes are coordinately regulated with other cell division genes under virtually all conditions. This expression pattern is strongly correlated with the expression of the forkhead transcription factor FoxM1, which binds to the majority of cell division promoters. These observations suggest that kinetochore gene up-regulation in cancer reflects a general activation of the cell division program and that altered expression of individual kinetochore genes is unlikely to play a causal role in tumorigenesis.Leukemia & Lymphoma Society of America (Scholar Award)National Institute of General Medical Sciences (U.S.) (Grant GM088313)American Cancer Society (Research Scholar Grant 121776)National Science Foundation (U.S.).

Effects of customer incivility on frontline employees and the moderating role of supervisor leadership style

Customer incivility toward frontline employees (FLEs) is a widespread phenomenon within tourism and hospitality industries, severely depleting the psychological resources of FLEs and delivered customer service. Drawing on the job demands-resources and conservation of resources frameworks, the current research compares the effects of the two most common forms of customer incivility on FLEs’ psychological responses and behavioral intentions (study 1). Moreover, this work explores the degree to which supervisor leadership style can mitigate the depleting effects of these two forms of customer incivility on FLEs (study 2). Findings demonstrate that FLEs’ responses to customer incivility episodes remain contingent upon supervisor’s leadership style and acknowledge that an empowering (vs. laissez-faire) leadership style can better mitigate the depleting effects of both customer incivility forms on FLEs’ role stress, rumination, retaliation and withdrawal intentions. The implications of these findings for tourism and hospitality theory and practicing managers are discussed

THE EFFECTS OF MATERNAL PERINATAL EXERCISE ON INFANT NEUROMOTOR OUTCOMES

BACKGROUND: Aerobic exercise during pregnancy has been well established as safe and effective for both mother and infant. Few studies have examined the effects of different exercise modes during pregnancy on infant outcomes. The purpose of this study is to examine the effects of exercise mode during pregnancy on 1-month infant neuromotor outcomes. METHODS: Pregnant women were recruited and randomized to either aerobic (AE), resistance (RE), combination (CE), or control (CON) groups. Participants completed 150 min each week of supervised activity. After delivery, 1-month infant neuromotor skills were assessed using the Alberta Infant Motor Scales (AIMs) and Peabody Developmental Motor Scales, 2nd Edition. ANOVAs were used to compare differences between exercise groups; data was stratified by pre-pregnancy BMI (healthy weight, HW vs. overweight-obese, OO) and infant sex (M, F). Regressions assessed predictors of 1-month neuromotor outcomes. RESULTS: Groups were similar in maternal, neonate, and 1-month descriptors. Trends for improved subscores included: AE and RE in Prone (p=.20); CE in Sitting (p=.11); RE in Standing (p=.20) relative to controls. In females (F) from Healthy Weight (HW) women, all exercise types had increased gestational age (p=.03), AE and CE had greater Stationary (p=.17) subscores; in males (M) of HW women, all exercise types had greater Sitting (p=.02) subscores. In F from OO women, AE had greater total AIMs score (p=.20), while AE and RE had greater Stationary (p=.02) Locomotion (p=.06) subscores, as well as GMQ (p=.05) scores; in M of OO women, all exercise with increased height (p=.03) and weight (p=.02), RE with greater Prone (p=.03) and Standing (p=.04) subscores, with greater total AIMS (p=.04) scores. Controlling for other factors, we found significant predictors of 1-month neuromotor scores. Reflex scores were predicted by maternal exercise attendance, pre-pregnancy activity, fitness level, ethnicity, infant sex and body fat. Stationary scores were predicted by exercise mode, pre-pregnancy activity, baby BMI. GMQ was predicted by maternal exercise mode, race, delivery type, pre-pregnancy activity, BMI, and 1-month body fat. CONCLUSION: Maternal exercise mode or attendance, and infant body fat influences 1-month neuromotor skills. There are differences in 1-month neuromotor outcomes based on infant sex as well as maternal pre-pregnancy BMI. Further research is needed to understand this

Short communication: Influence of retainer configuration and loading direction on the stress distribution of lithium disilicate resin-bonded fixed dental prostheses: 3D finite element analysis

The present study elucidates the mechanical performance of different designs of resin-bonded fixed dental prostheses made of lithium disilicate simulating masticatory loads of anterior or canine guidance. A three-dimensional model of maxilla was constructed containing central incisor and canine teeth, with edentulous space of the lateral incisor. Three designs of prosthesis were created: retained in central incisor (1-I), retained in canine (1-C) and fixed in both teeth (2-IC). The computational analysis was performed for load in canine and central incisor separately (100N, 45°). The tensile and shear stresses were calculated for the resin-bonded fixed dental prosthesis, bonding surface of each retainer and cement layer using 3D finite element analysis. The 20 highest stress values were analyzed using two-way ANOVA and post-hoc Tukey test, all with α = 5%. The computational analysis showed that 2-retainer resin-bonded fixed dental prosthesis presented the worst prognosis regardless of the mandibular movement. ANOVA showed that Mandibular movement*Retainer interaction influenced on the tensile and shear stresses values (p < 0.01). Higher stresses were observed in the connector region for all groups (13-82.2 MPa; 11-70.2 MPa). In order to reduce the stress concentration in the resin-bonded fixed dental prosthesis and the retainer made of lithium disilicate, the occlusion may serve as the selection criteria of the unitary abutment for better sustainability
