Maxillary sinus textiloma: a case report
<p>Abstract</p> <p>Introduction</p> <p>Textilomas have been reported in many locations. We report the first case of textiloma located in the maxillary sinus that mimicked a sinus cyst recurrence on computed tomography images.</p> <p>Case presentation</p> <p>A 60-year-old Caucasian man was referred for persistent infection of the right maxillary sinus. A maxillary sinus benign cyst had been removed three months before. Computed tomography showed a sinus opacity evoking a cyst recurrence. A new operation was planned to remove the cyst by a Caldwell-Luc approach. After excision of very thick fibrous tissue, a compress was discovered in the maxillary sinus. The patient did not present with any sinus infection after the operation.</p> <p>Conclusion</p> <p>The surgeon should always take into account the possibility of textilomas in a patient with a history of sinus surgery.</p
Osteoinduction in human fat derived stem cells by recombinant human bone morphogenetic protein-2 produced in Escherichia coli
Bioactive recombinant human bone
morphogenetic protein-2 (rhBMP-2) was obtained
using Escherichia coli pET-25b expression system:
55 mg purified rhBMP-2 were achieved per g cell dry
wt, with up to 95% purity. In murine C2C12 cell line,
rhBMP-2 induced an increase in the transcription of
Smads and of osteogenic markers Runx2/Cbfa1 and
Osterix, measured by semi-quantitative RT-PCR.
Bioassays performed in human fat-derived stem cells
showed an increased activity of the early osteogenic
marker, alkaline phosphatase, and the absence of
cytotoxicity

Agreement of Self-Reported and Genital Measures of Sexual Arousal in Men and Women: A Meta-Analysis
The assessment of sexual arousal in men and women informs theoretical studies of human sexuality and provides a method to assess and evaluate the treatment of sexual dysfunctions and paraphilias. Understanding measures of arousal is, therefore, paramount to further theoretical and practical advances in the study of human sexuality. In this meta-analysis, we review research to quantify the extent of agreement between self-reported and genital measures of sexual arousal, to determine if there is a gender difference in this agreement, and to identify theoretical and methodological moderators of subjective-genital agreement. We identified 132 peer- or academically-reviewed laboratory studies published between 1969 and 2007 reporting a correlation between self-reported and genital measures of sexual arousal, with total sample sizes of 2,505 women and 1,918 men. There was a statistically significant gender difference in the agreement between self-reported and genital measures, with men (r = .66) showing a greater degree of agreement than women (r = .26). Two methodological moderators of the gender difference in subjective-genital agreement were identified: stimulus variability and timing of the assessment of self-reported sexual arousal. The results have implications for assessment of sexual arousal, the nature of gender differences in sexual arousal, and models of sexual response
Year in review 2007: Critical Care – multiple organ failure and sepsis
Several research papers published in Critical Care throughout 2007 examined the pathogenesis, diagnosis, treatment and prognosis of sepsis and multiorgan failure. The present review summarizes the findings and implications of the papers published on sepsis and multiorgan failure and places the research in the context of other work in the field
