Context: The aim of this article is to develop the Spanish adaptation of the internal functioning of Work Teams Scale (QFI-22).', 'The scale was adapted from the French version, and was applied to a sample of 1,055 employees working for firms operating in Spain. The article analyses the internal structure (exploratory and confirmatory factor analysis) and internal consistency, and provides convergent validity evidence of the scale.', 'The QFI-22 scale shows the same internal structure as the original. Factor analysis confirmed the existence of two factors: interpersonal support and team work management, with good internal consistency coefficients (1 = .93, 2 = .92). Regarding validity evidence, the QFI-22 scale has significant correlations with other correlates and alternative scales used for comparison purposes. The two factors correlated positively with team vision, participation safety, task orientation and support for innovation (Team Climate Inventory, TCI scale), with progressive culture (Organisational Culture, X-Y scale), and with creating change, customer focus and organisational learning (Denison Organizational Culture Survey, DOCS scale). In contrast, the two factors correlated negatively with traditional culture (X-Y scale).
Answer: The QFI-22 scale is a useful instrument for assessing the internal functioning of work teams.

Context: Adipocytes express inflammatory mediators that contribute to the low-level, chronic inflammation found in obese subjects and have been linked to the onset of cardiovascular disorders and insulin resistance associated with type 2 diabetes mellitus. A reduction in inflammatory gene expression in adipocytes would be expected to reverse this low-level, inflammatory state and improve cardiovascular function and insulin sensitivity. The natural products, curcumin and resveratrol, are established anti-inflammatory compounds that mediate their effects by inhibiting activation of NF-kappaB signaling. In the present study, we examined if these natural products can inhibit NF-kappaB activation in adipocytes and in doing so reduce cytokine expression.', 'Cytokine (TNF-alpha, IL-1beta, IL-6) and COX-2 gene expression in 3T3-L1-derived adipocytes was measured by quantitative real-time PCR (qRT-PCR) with or without TNFalpha-stimulation. Cytokine protein and prostaglandin E2 (PGE2) expression were measured by ELISA. Effects of curcumin and resveratrol were evaluated by treating TNFalpha-stimulated adipocytes with each compound and 1) assessing the activation state of the NF-kappaB signaling pathway and 2) measuring inflammatory gene expression by qRT-PCR and ELISA.', 'Both preadipocytes and differentiated adipocytes express the genes for TNF-alpha, IL-6, and COX-2, key mediators of the inflammatory response. Preadipocytes were also found to express IL-1beta; however, IL-1beta expression was absent in differentiated adipocytes. TNF-alpha treatment activated NF-kappaB signaling in differentiated adipocytes by inducing IkappaB degradation and NF-kappaB translocation to the nucleus, and as a result increased IL-6 (6-fold) and COX-2 (2.5-fold) mRNA levels. TNF-alpha also activated IL-1beta gene expression in differentiated adipocytes, but had no effect on endogenous TNF-alpha mRNA levels. No detectable TNFalpha or IL-1beta was secreted by adipocytes. Curcumin and resveratrol treatment inhibited NF-kappaB activation and resulted in a reduction of TNF-alpha, IL-1beta, IL-6, and COX-2 gene expression (IC50 = 2 muM) and a reduction of secreted IL-6 and PGE2 (IC50 ~ 20 muM).
Answer: Curcumin and resveratrol are able to inhibit TNFalpha-activated NF-kappaB signaling in adipocytes and as a result significantly reduce cytokine expression. These data suggest that curcumin and resveratrol may provide a novel and safe approach to reduce or inhibit the chronic inflammatory properties of adipose tissue.

Context: To investigate the role of the superficial zone in regulating the frictional response of articular cartilage. This zone contains the superficial protein (SZP), a proteoglycan synthesized exclusively by superficial zone chondrocytes and implicated in reducing the friction coefficient of cartilage.', 'Unconfined compression creep tests with sliding of cartilage against glass in saline were carried out on fresh bovine cylindrical plugs (slashed circle 6 mm, n=35) obtained from 16 bovine shoulder joints (ages 1-3 months). In the first two experiments, friction tests were carried out before and after removal of the superficial zone ( approximately 100 microm), in a control and treatment group, using two different applied load magnitudes (4.4 N and 22.2 N). In the third experiment, friction tests were conducted on intact surfaces and the corresponding microtomed deep zone of the same specimen.', 'In all tests the friction coefficient exhibited a transient response, increasing from a minimum value (mu(min)) to a near-equilibrium final value (micro(eq)). No statistical change (P>0.5) was found in micro(min) before and after removal of the superficial zone in both experiments 1 and 2. However, micro(eq) was observed to decrease significantly (P<0.001) after removal of the surface zone. Results from the third experiment confirm that micro(eq) is even lower at the deep zone. Surface roughness measurements with atomic force microscopy (AFM) revealed an increase in surface roughness after microtoming. Immunohistochemical staining confirmed the presence of SZP in intact specimens and its removal in microtomed specimens.
Answer: The topmost ( approximately 100 microm) superficial zone of articular cartilage does not have special properties which enhances its frictional response.

Does removal of the superficial zone of bovine articular cartilage increase its frictional coefficient?
