We previously derived a typology of schizophrenia from a latent class analysis of 447 first-contact non-affective functional psychotic patients from a defined catchment area. Here, using the same sample, we show that the three subtypes, 'neurodevelopmental' (Type A), 'paranoid' (Type B) and 'schizoaffective' (Type C) have different premorbid, phenomenological and treatment response characterist...

the term “serological epidemiology” is based to describe a method which has unique applications in comparing the immunologic status and health experiences of various populations, especially among populations for which morbidity data and vital statistics are scanty or completely lacking, or for inaccessible areas where the collection of serum is made with difficulty. serologic and hematological ...

h.pylori infection stimulates immune responses. these responses at the mucosal level are predominantly of iga types, while circulating antibodies against this microorganism are predominantly igg classes. igm antibodies are rarely found and seem to be non-specific for this bacterium. in this research, water extract antigen, from three strains of h.pylori (isolated from patients with gastritis, d...

The 2 2 model of perfectionism examines the relation between four subtypes of perfectionism and psychological adjustment (Gaudreau & Thompson, 2010). Researchers have investigated subtypes of perfectionism using common multivariate statistical analyses. The development of a new measure is warranted to evaluate whether individuals can, with a decent degree of certainty, assess by themselves thei...

results in this setting, detection rate of the disease is 34.86%, if the high normal titer for the wrights test titer assumed 1/80 and is 44.95% if the titer assumed 1/40, while elisa test had detection rate of 58.72% for those suspicious cases. furthermore, the detection rate for diagnosis of active brucellosis with 2me tests was 17.54% with high normal titer of 1/80 and was 59.64% with a high...

in an attempt to convert mass vaccination practices to the extended programme on immunization, a sero-evaluation study was carried out in rural iran in 1976. a total of 22 246 rural children of 2-12 years of age were sampled. blood samples taken on filter paper were tested by indirect hemagglutination technique to determine the level of circulating antibodies against tetanus toxoid. tetanus was...

introduction : human cytomegalovirus (hcmv) is able to go into latency and is the most common cause of congenital infections in humans. its clinical manifestations range from asymptomatic forms to severe fetal damage, and in rare cases, fetal death due to abortion. this prospective cross-sectional study was designed to determine the seroprevalence of hcmv infection in pregnant women attending a...

background: brucellosis is a zoonotic disease and its symptoms and appearances are not exclusive in human and its tradi­tional diagnosis is based on blood culture and serological methods. for more sensitive and specific detection, the pcr method is recommended. methods: one hundred four blood samples were gathered from suspicious patients with brucellosis different ages form ker­manshah, mazand...

conclusions findings of this study demonstrate no significant difference between levels of h. pylori specific antibodies of iga, igg, anti-caga and the presence of pcos disorders, and also indicate that serologic testing is a sensitive method for the detection of h. pylori antibodies. the high prevalence of h. pylori positive antibody levels in both pcos and non-pcos patients can be probably as...

helicobacter pylori (h.pylori) is the most common human infection in the world. this agent has a strong role in pathogenesis of chronic gastritis and peptic ulcers. therefore introducing of simple and cost effective and non invasive tests are important for diagnosis of h.pylori infections. in this study 215 patient suffering from different gastrointestinal disorders referred to gi endoscopy dep...
