OBJECTIVE To use sonography in a follow-up study aimed at assessing the size of the thymus in healthy infants, and to search for a possible relation to clinical variables, breast-feeding status, and illness. MATERIAL AND METHODS Forty-seven healthy infants were examined as neonates and re-examined at 4 months of age. Thirty-seven of the infants were also(More)
Studies based on databases, medical records and registers are used extensively today in epidemiological research. Despite the increasing use, no developed methodological literature on use and evaluation of population-based registers is available, even though data collection in register-based studies differs from researcher-collected data, all persons in a(More)
Paratuberculosis is a chronic infection of ruminants and other species caused by Mycobacterium avium ssp. paratuberculosis (Map). Establishing test strategies for paratuberculosis will require insight into the temporal aspects of certainty with a given test. In this study, the age at which cows tested positive by ELISA and fecal culture (FC) was(More)
BACKGROUND Northern Vietnam is an endemic region for fish-borne zoonotic trematodes (FZT), including liver and intestinal flukes. Humans acquire the FZT infection by eating raw or inadequately cooked fish. The production of FZT-free fish in aquaculture is a key component in establishing a sustainable program to prevent and control the FZT transmission to(More)
AIM To assess the variation in size of the thymus in vivo in preterm neonates and to identify relations between thymic size and gestational age (GA), birthweight, occurrence of postnatal infections and maternal alcohol and tobacco intake during pregnancy. METHODS Eighty preterm neonates with a GA between 24 and 36 wk, and a birthweight between 490 and(More)
Bangladesh faced two epidemic waves of highly pathogenic avian influenza (HPAI) H5N1 in two consecutive years. The peaks of the waves were observed in February-July 2007 and January-April 2008, respectively. We examined the spatial and temporal patterns of the 293 outbreaks in 143 subdistricts in 2007 and 2008. Global clustering assessed by K-function was(More)
Bangladesh has been severely hit by highly pathogenic avian influenza H5N1 (HPAI-H5N1). However, little is known about the genetic diversity and the evolution of the circulating viruses in Bangladesh. In the present study, we analyzed the hemagglutinin gene of 30 Bangladeshi chicken isolates from 2007 through 2010. We analyzed the polybasic amino acid(More)
OBJECTIVE To assess whether physical training induces cardiac hypertrophy and valvular regurgitation in maturing Standardbred trotters and to establish a prediction model for the size of the left ventricle. DESIGN Longitudinal observational study. ANIMALS 53 Standardbred trotters. PROCEDURES Each horse underwent 2-D, M-mode, and color flow Doppler(More)
This study determines levels of regulatory T cells (T(regs)), naive T(regs), immune activation and cytokine patterns in 15 adult human immunodeficiency virus (HIV)-infected patients receiving prolonged highly active anti-retroviral therapy (HAART) who have known thymic output, and explores if naive T(regs) may represent recent thymic emigrant T(regs).(More)
Infection with human immunodeficiency virus (HIV) causes a dysregulation of the immune system. This is caused by HIV-specific as well as non-specific mechanisms and has not been explained fully. In particular, knowledge is lacking about the potential role of host-mediated immunosuppressive mechanisms. During recent years it has become evident that a(More)
