BACKGROUND Prior research has identified several components of the innate immune system that may play a significant role in chronic rhinosinusitis (CRS), but the role of innate immunity in patients with CRS is poorly understood. The objective of this study was to determine differential expression of innate immunity genes in the mucosa of patients with CRS with nasal polyposis (CRSwNP) and CRS w...

In order to explore the role of IL-22 in the pathogenesis of CRS, we observed the expression of IL-22 and associated factors in chronic rhinosinusitis with nasal polyps (CRSwNP) and chronic rhinosinusitis without nasal polyps (CRSsNP). Immunohistochemical staining was applied to detect the expression of IL-22, IL-22R, STAT3, retinoic acid orphan receptor C (RORC) and aryl hydrocarbon recptor (A...

Orthotopic rat liver transplantation (OLT) is a complex microsurgical procedure extensively applied to basic science, myriad complications can occur, but incision-related self-biting has not been reported after OLT. For the project of tolerance induction through stem cells, we performed OLT from Lewis Brown Norway (BN) rats as an acute rejection model and divided study was into transverse incis...

PURPOSE To investigate refraction, corneal curvature, axial components, and the correlations between the refraction and ocular growth during the emmetropization in the C57BL/6 mouse. METHODS Ten groups of 10 mice underwent ocular measurements at 22 to 102 days after birth. Refraction was measured by photoretinoscopy and corneal radius of curvature (CRC) was measured by keratometry. Corneal th...

Rat brown adipocytes at day 22 of foetal development showed greater size, higher mitochondria content and larger amounts of lipids, as determined by flow cytometry, than 20-day foetal cells. Simultaneously, an inhibition on the percentage of brown adipocytes into S+G2/M phases of the cell cycle was observed between days 20 and 22 of foetal development. The expression of several adipogenesis-rel...

The pituitary gland is a neuroendocrine organ that works closely with the hypothalamus to affect multiple processes within the body including the stress response, metabolism, growth and immune function. Relative tissue expression (rEx) is a transcriptome analysis method that compares the genes expressed in a particular tissue to the genes expressed in all other tissues with available data. Usin...

AIM The aim of this study was to investigate differences in mortality up to 1 year of age in extremely preterm infants (before 27 weeks) born in seven Swedish healthcare regions. METHODS National prospective observational study of consecutively born, extremely preterm infants in Sweden 2004-2007. Mortality was compared between regions. Crude and adjusted odds ratios and 95% CI were calculated...
