BACKGROUND The quantitation of human milk oligosaccharides (HMOs) is challenging because of the structural complexity and lack of standards. OBJECTIVE The objective of our study was to rapidly measure the absolute concentrations of HMOs in milk using LC-mass spectrometry (MS) and to determine the phenotypic secretor status of the mothers. METHODS This quantitative method for measuring HMO c...

An association between blood group A and cancer of the stomach was first reported by Aird, Bentall, and Fraser Roberts (1953). Further associations between blood groups and gastrointestinal disorders have since been described (Clarke, 1964a). This paper reports an investigation into the ABO blood group distribution and salivary secretor status of patients with infantile hypertrophic pyloric ste...

OBJECTIVES To determine the association between printing works and nasopharygeal carcinoma as well as other diseases. METHODS Demographic data were obtained for those who had worked in a particular newspaper company since its establishment in 1950. Through access to the data bank of the hospital records of the Labor Insurance Bureau for 1985-94, all workers were identified who had been admitt...

Centre and purified using the appropriate Synsorbs (Chembiomed Ltd., Alberta, Canada). Monoclonal anti-A was isolated in the M.R.C. Human Biochemical Genetics Unit. In one experiment lactase from two individuals of different blood group (A and 0) was purified by immunoaffinity chromatography as described in Potter et al. (1985). Using the A blood-group specific antibodies and the lectin from He...

The observation that ABO agglutinins are present in a wide variety of pollens (Denborough, 1964) and so must commonly be inhaled, and the knowledge that plant agglutinins are antigenic (Mikela, 1957), prompted us to study secretor status in allergic disease of the respiratory tract, namely in asthma and hay fever. The opportunity has been taken to measure the amount of isoagglutinins present in...

The current study was carried out on 550 healthy population having 250 males and 300 females. Five ml venousblood was collected following standard biosafety measures. ABO blood grouping was done by Tile method and found blood group B dominant in both sexes i.e 180 male and 120 female were found with blood group B. Moreover, 2 ml of saliva was also collected from allvolunteers. Secretor status w...
