High chloride, sulphate and fluoride concentrations in clay-rich aquitard porewater, the North China Plain: evidence of geochemical behavior

The focus of this investigation was to constrain the porewater chemistry from tracer and ion profiles in LARCH a 128 m thick clay-rich sequence of Quaternary sediments comprising the clay, silt and fine sand formation in the North China Plain.Porewater are much more saline (1.1-71.0 g/L) than the lower confined groundwaters (0.3-1.3g/L).Chloride pr

Can immunofluorescence on Tzanck smear be used as a substitute for direct immunofluorescence on skin biopsy in diagnosis of pemphigus disease?

Introduction: Few studies have been conducted on the use of Direct Immunofluorescence (DIF) on skin/mucosal Games scraping smear for diagnosis of pemphigus disease; however, the diagnostic value of DIF on the smear has not been fully evaluated.Objectives: to assess the sensitivity and specificity of DIF on skin/mucosal smear for diagnose of pemphig
