Preterm birth is the major cause of neonatal mortality and morbidity. In many cases, it has severe life-long consequences for the health and neurological development of the newborn child. More than 50% of all preterm births are spontaneous, and currently there is no effective prevention. Several studies suggest that genetic factors play a role in(More)
Preterm birth is the major cause of neonatal death and serious morbidity. Most preterm births are due to spontaneous onset of labor without a known cause or effective prevention. Both maternal and fetal genomes influence the predisposition to spontaneous preterm birth (SPTB), but the susceptibility loci remain to be defined. We utilized a combination of(More)
BACKGROUND Adenosine triphosphate (ATP)-binding cassette transporter A3 (ABCA3) gene mutations cause fatal respiratory failure in term infants, but common ABCA3 polymorphisms have remained uncharacterized at the population level. AIM To define a subset of tagging single-nucleotide polymorphisms (tSNPs) which capture most of the variation within the ABCA3(More)
Preterm birth (delivery at less than 37 weeks of gestation) is the leading cause of infant mortality worldwide. So far, the application of animal models to understand human birth timing has not substantially revealed mechanisms that could be used to prevent prematurity. However, with amassing data implicating an important role for genetics in the timing of(More)
Bronchopulmonary dysplasia (BPD) is a common chronic lung disease associated with very preterm birth. The major risk factors include lung inflammation and lung immaturity. In addition, genetic factors play an important role in susceptibility to moderate-to-severe BPD. In this study, the aim was to investigate whether common polymorphisms of specific genes(More)
Haptoglobin (Hp), a hemoglobin-binding protein, is known as an acute phase protein and increases during the acute phase of inflammation in most mammals. We reported previously in brown bears that the mean Hp concentrations were higher in blood samples obtained in winter than those in spring. To examine a possible relation of the seasonal variations of Hp to(More)
INTRODUCTION Preterm birth is the major cause of mortality and morbidity in neonates. Intrauterine infection and/or inflammatory response are evident in 60-70% of spontaneous preterm births (SPTBs). Genetic factors significantly increase this risk. However, the genetic background associated with SPTB is poorly understood. Surfactant protein (SP) A, SP-D,(More)
BACKGROUND Surfactant protein (SP) C has been shown to be expressed also outside pulmonary alveoli. Certain SP-C gene (SFTPC) polymorphisms associate with lung diseases and very preterm birth. AIMS We investigated the association of SFTPC single nucleotide polymorphism (SNP) rs4715 with factors affecting spontaneous preterm birth and characterized the(More)
Localization of receptor-bound human chorionic gonadotropin (hCG) in rat testis was studied by the peroxidase-antiperoxidase (PAP) complex method. The rats were injected with a single intravenous dose (1000 IU) of hCG. Three, 6, 12, and 24 hr after injection the testes were removed for localization of the hormone. The hormone localized to the periphery of(More)
Spontaneous preterm birth (SPTB) is a major factor associating with deaths and with lowered quality of life in humans. Environmental and genetic factors influence the susceptibility. Previously, by analyzing families with recurrent SPTB in linkage analysis, we identified a linkage peak close to the gene encoding CXCR3. Present objectives were to investigate(More)
