Barrett's esophagus (BE), a complication of gastroesophageal reflux disease, is associated with an increased risk of esophageal cancer. Mitogen‐activated protein kinases may play an important role in the pathogenesis of this process. We aimed to evaluate mitogen‐activated protein kinases activity in esophageal mucosa of patients with BE and find possible relationship between reflux type and BE. Twenty‐four...
The Raman lattice modes in the LiCsSO4 crystal were measured in the temperature range of 17–303 K. Two right‐angle scattering geometries were used: z(xx)y and z(xz)y, to observe Ag and Bg (or B2g) modes, respectively. Critical phenomena were observed in the spectra at temperatures of about 200, 180 and 100 K. They correspond to structural phase transitions in the crystal from D2h to C2h at 200 K and...
