OBJECTIVES To determine whether women who have ha da pregnancy in which the fetus is affected by a neural tube defect (NTD) know of current folic acid recommendations; whether the recommendations are followed before or during the pregnancy associated with an NTD and subsequent pregnancies; and to insure that women who have had an NTD-affected pregnancy have access to proper information about NT...
Egress of lipoprotein-derived cholesterol from lysosomes requires two lysosomal proteins, polytopic membrane-bound Niemann-Pick C1 (NPC1) and soluble Niemann-Pick C2 (NPC2). The reason for this dual requirement is unknown. Previously, we showed that the soluble luminal N-terminal domain (NTD) of NPC1 (amino acids 25-264) binds cholesterol. This NTD is designated NPC1(NTD). We and others showed ...
RlmG is a specific AdoMet-dependent methyltransferase (MTase) responsible for N²-methylation of G1835 in 23S rRNA of Escherichia coli. Methylation of m²G1835 specifically enhances association of ribosomal subunits and provides a significant advantage for bacteria in osmotic and oxidative stress. Here, the crystal structure of RlmG in complex with AdoMet and its structure in solution were determ...
Neural tube defects (NTD) are severe congenital malformations and can be fatal. These malformations constitute one of the principal causes of mortality and morbidity in childhood. Classically, NTD have been divided into two main groups: (a) defects affecting cranial structures, such as anencephaly and encephalocele, and (b) defects involving spinal structures (spina bifida) (Verrotti et al., 20...
ABSTRACT In this study we have tried to analyse the effect of vit.A ampule(retinol )on formation of neural tube (neurulation)in mouse (balb/c)embryo to determine the critical time of its formation and the optimum teratogenic dose of this substance in the experimental induction of neral tube defects(NTD). After we observed the vaginal plug(v.p=0day),mated animals were divided into two groups ...
The feeding behaviour and growth rates of Asian seabass (Lates calcarifer Bloch, 1790) fry were studied using a new type demand (NTD) feeder. This system was equipped with programme to detect hunger in fish automatically dispense pellets. system could overcome hierarchy during feeding. Fish rearing experiments conducted compare the NTD feeder infrared light (ILD) automatic timer (AT) feede...
Background and purpose : Çongenital anomalies are common causes of mortality & morbidity in children. Ïts treatment and rehabilitation imposes high economic burden on the society. The oceurence of the defects in newborns with congenital, environmental or both factors is 3-5% . The purpose of this study was to evaluate the incidence of Gross congenital neural tube defect in newborns at obst...
Neural tube defects (NTDs) are common birth defects, whose specific biomarkers are needed. The purpose of this pilot study is to determine whether protein profiling in NTD-mothers differ from normal controls using SELDI-TOF-MS. ProteinChip Biomarker System was used to evaluate 82 maternal serum samples, 78 urine samples and 76 amniotic fluid samples. The validity of classification tree was then...
