Inside the competences evaluation, the stress tolerance of students. An empirical study based on conservation of resources theory

Competence development is considered a preventive strategy of burnout. At an organizational context some competences could be linked as precursors or consequences. In self-assessment of competence development, students perceive stress tolerance as a priority competence to ameliorate. Moreover employers and recruitment consultants agree that this is a new authentic challenge for organizations. The main reasons of this result are debated, this study should consider the importance of competence development from a holistic point of view. In addition it considers the exploration of the relationship between stress tolerance and competence development, according to Conservation Resources (COR) theory (Hobfoll 1988, 1989, 1998, 2004) where the resource loss is considered the principal component in the stress process

Immunomodulation and metabolism: possible role of lactoferrin

To gain insight in the relationship between innate immune system and metabolic disease, we aimed to investigate the effects of lactoferrin in obesity-related metabolic disturbances. Circulating lactoferrin concentration was significantly decreased in subjects with altered glucose tolerance (AGT) and associated negatively with obesity-related metabolic disturbances. The SNPs-induced aminoacidic changes in lactoferrin N-terminus region were associated with a low atherogenic lipid profile. Lactoferrin production in neutrophils decreased significatively in aging, chronic low-grade inflammation and type 2 diabetes. In vitro, lactoferrin increased insulin signaling pathway, even under insulin resistance conditions and displayed dual effects on adipogenesis (antiadipogenic in 3T3-L1 and adipogenic in human adipocytes). In conclusion, lactoferrin might play a potential protective role against insulin resistance and obesity related metabolic disturbances.
