A simple culture procedure and assay conditions are described which have permitted us to quantify the synthesis of proteins which are associated with an osteoblastic phenotype, by rat calvarial periosteal cells grown on particulate materials. The main feature of the method is the use of an adhesive which does not permit cells to attach to itself but allows attachment and growth of cells on material particles embedded in it on glass coverslips. Cells were cultured for 27 d on hydroxyapatite particle-coated coverslips. Alkaline phosphatase, osteopontin and collagen type I were monitored in cell lysates from d 10 to d 20. After Western blotting, osteopontin and collagen type I were quantified using specific antisera and enhanced chemiluminescence. Maximum levels coincided with peak alkaline phosphatase activity, after 10 and 17 d. The procedures described will be generally applicable to the comparison of cell behaviour on particulate substrata.

Introduction: Assessing gender disparity in surgical trainees' operative opportunities and experience quantifies implicit gender bias and reflects a summation of many smaller biased interactions within the operating room environment. Highlighting gender disparity in surgery informs a platform for advocacy.
Methods: A systematic literature search was performed using Medline, Web of Science, OpenMD and Science Direct consistent with the Preferred Reporting Items for Systematic Reviews and Metanalysis guidelines.

Objective: Trichomoniasis is a globally prevalent sexually transmitted infection caused by the protozoan Trichomonas vaginalis. Polymerase chain reaction (PCR) is the gold standard for diagnosing trichomoniasis, but it is expensive. Antigen tests are immunochromatographic immunoassays that detect T.

Objective: To examine the predictive strength of cardiorespiratory fitness (CRF), motor competence (MC), maternal educational status, and parental perception of their children's favorite leisure activities for meeting physical activity (PA) guidelines of each gender among children aged 3-6 years.
Methods: This is a cross-sectional study with 367 preschoolers (53% girls), assessing CRF (PREFIT 20m shuttle run), MC (battery of motor skills), PA (accelerometry), maternal education and parental perception of children's preferred leisure (questionnaires). Factorial analysis of covariance, multiple logistic regression, and chi-square tests were conducted.

Purpose: This study aimed to adapt the Montreal Cognitive Assessment Hearing Impaired (MoCA-H) into Brazilian Portuguese (BP).
Methods: This was a descriptive, cross-sectional, quantitative, and qualitative study involving participants selected by convenience. The instrument was adapted from its original version, in a six-stage process consisting of the following: Stage 1 - Translation and back translation of the MoCA-H; Stage 2 - Stimulus analysis and selection; Stage 3 - Semantic analysis of stimuli; Stage 4 - Analysis by non-expert judges, part 1; Stage 5 - Analysis by non-expert judges, part 2; Stage 6 - Pilot study.

Objective: To conceptualise the cognitive processes of early expert decision-making in urgent care.
Background: Expert clinicians in the UK frequently determine suitable urgent care patient pathways via telephone triage. This strategy is promoted by policymakers but how it is performed, and its effectiveness has not been evaluated.
