OBJECTIVES To investigate the expression of epidermal growth factor receptor (EGFR) messenger RNA (mRNA) in human sinus mucosa and to compare the expression of EGFR and EGF among patients with chronic rhinosinusitis (CRS), patients with CRS and nasal polyposis (CRS/NP), and a healthy control group. DESIGN Maxillary sinus ostia mucosa was harvested from patients undergoing endoscopic sinus sur...

Congenital rubella syndrome (CRS) can occur in children whose mothers contract the rubella virus, sometimes called German measles, during pregnancy [2]. Depending on the gestational period when the mother contracts rubella, an infant born with CRS may be unaffected by the virus or it may have severe developmental defects. The most severe effects of the virus on fetal development occur when the ...

Coherent Raman scattering (CRS) microscopy is a high-speed vibrational imaging platform with the ability to visualize the chemical content of a living specimen by using molecular vibrational fingerprints. We review technical advances and biological applications of CRS microscopy. The basic theory of CRS and the state-of-the-art instrumentation of a CRS microscope are presented. We further summa...

Introduction: Chronic rhinosinusitis (CRS) with and without nasal polyposis is a chronic inflammatory disease of the sinuses and nasal mucosa. Recent evidence has indicated a relationship between serum 25-hydroxyl vitamin D (OH-VitD) deficiency and CRS. Regarding this, the present study aimed to compare the serum level of 25-OH-VitD in CRS patients with and without nasal polyposis and control g...

This vignette outlines the implementation of the regression spline method contained in the R crs package, and also presents a few illustrative examples.
