PURPOSE Knowledge of the long-term clinical outcome of Raynaud's syndrome (RS), essential both for patient counselling and formulation of optimal therapeutic recommendations, is conspicuously deficient in current medical literature. We have prospectively monitored 1039 patients with RS, 118 (11.4%) for more than 10 years to determine whether initial characterization was able to predict outcome....

Abstract Background The seasonal human coronaviruses (HCoV) NL63, 229E, OC43 and HKU1, are endemic throughout the world, yet majority of HCoV infections remain undiagnosed. Serology can reliably identify individuals previously infected with HCoVs. Methods In a cross-sectional seroprevalence study, 2,389 serum samples were collected from children adults requiring hospital admission in France 202...

This study was conducted at the Agricultural Research Station, Hada El-Sham, King Abdulaziz University during 2006 and 2007 seasons. Four canola varieties, Callypso, Pactole, Sero-4 and Sero-6 varieties were tested under four nitrogen fertilizer rates (0.00, 92,138 and 184 kg N/ha) to determine the effect of nitrogen fertilizer on the canola (Brassica napus L.) seed yield, yield components and ...

A total of 332 dairy cow’s sera samples were collected from Kombolcha and Dessie districts North Ethiopia to determine the sero-prevalence infectious bovine rhinotracheitis (IBR), Brucellosis. Sera split into equal portions competitive ELISA was used for testing IBR in first portion while Rose Bengal test (RBT) Complement Fixation Test (CFT) detection Brucellosis second portion. Sero-posi...

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 ...

Brucellosis is a key zoonosis of major public health, animal welfare and economic significance, and is endemic in livestock in Uganda. A cross-sectional epidemiological study was carried out to estimate the sero-prevalence of brucellosis and identify factors associated with sero-positivity in cattle in urban and peri-urban Gulu and Soroti towns of Northern and Eastern Uganda, respectively. A to...

background: the aim of this study was to conduct a sero-epidemiological survey in isfahan city and suburb areas, central iran to detect the rate of human hydatidosis using elisa test. methods: overall, 635 serum samples were collected from subjects referred to different health centers in urban and rural regions of the city. sera were analyzed using ag-b elisa test. ten μg/ml antigens, serum dil...

Sentinel herds and samples submitted by private equine practitioners were used to determine the sero-prevalence and sero-incidence of African horse sickness virus (AHSV) and equine encephalosis virus (EEV) in horse and donkey populations in the Highveld region of Zimbabwe. The sero-prevalence and sero-incidence of antibodies against these viruses were determined using the competitive enzyme-lin...

BACKGROUND There have been suggestions of an association between Chlamydia pneumoniae, chlamydial heat shock protein (Ch-hsp) 60 and human heat shock protein (h-hsp) 60 infection sero-status and development of secondary cardiovascular events. Patients with diabetes might be at higher risk since they are prone to infections. The objective of this study was to investigate prospectively the role o...

BACKGROUND HIV counselling and testing (HCT) services can play an important role in HIV prevention by encouraging safe sexual behaviours and linking HIV-infected clients to antiretroviral therapy (ART). However, regular repeat testing by high-risk HIV-negative individuals is important for timely initiation of ART as part of the 'treatment as prevention' approach. AIM To investigate HCT use du...
