Vitamin D deficiency in pregnancy may be associated with increased offspring adiposity, but evidence from human studies is inconclusive. We examined associations between prenatal vitamin D intake, 25-hydroxyvitamin D (25(OH)D) in cord blood, and offspring size and body composition at birth and 5 months. Participants included 605 mother-offspring dyads from the Healthy Start study, an ongoing, pre-birth prospective cohort study in Denver, Colorado, USA. Prenatal vitamin D intake was assessed with diet recalls and questionnaires, and offspring body composition was measured via air displacement plethysmography at birth and 5 months...

Beyond prostaglandins, the function of eicosanoids and other oxylipins in pregnancy and labor is poorly understood. In contrast to earlier work focusing on preterm infants, we investigated how oxylipin levels in newborns (measured in cord blood) vary during the last weeks of pregnancy in 190 mother-newborns (≥37 weeks of gestation) of the ENVIRONAGE birth cohort, Belgium. We found increased levels of PGE2 (p=0.003), PGF2α (p=0.042), 8,9-DHET (p=0.037), 11-HETE (p=0.034), and 15-HETrE (p=0.008) associated with full term pregnancy compared to early term labor...

Exposure to high-dose benzene leads to the inhibition of erythroid differentiation. However, whether lower doses of benzene exposure resemble high-dose effects in erythroid differentiation, as well as the underlying mechanisms, remains largely unknown. To identify the microRNAs (miRNAs) specifically responsible for benzene exposure and their regulatory role in erythroid differentiation, we performed miRNA microarray in CD34(+) hematopoietic progenitor cells isolated from human umbilical cord blood after treatment with hydroquinone (HQ), a metabolite of benzene at concentrations of 0, 1...

CCR5 is a chemokine receptor that also was found to be used by HIV as a co-receptor for entering target cells. A 32 bp deletion was described in certain people that rendered CCR5 non-functional. The mutant allele CCR5-Δ32 has been shown to prevent HIV infection. In addition, stem cell transplantation with the CCR5-Δ32 homozygous genotype can lead to clearance of HIV infection. In this study, our aim was to investigate the frequency of CCR5-Δ32 mutation in a cohort of stem cell donors from cord blood bank and stem cell donor registry...

Dendritic cells (DCs) orchestrate immune responses after allogeneic hematopoietic cell transplantation (HCT). We studied the association of donor myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) recovery in the landmark analysis of umbilical cord blood (UCB) and matched related donor (RD) HCT. Eighty patients (42 UCB and 38 RD recipients) with a day 100 (D+100) blood sample were included in the analysis. Median age was 51 years (20-71). Most patients had acute leukemia (50%) or lymphoma (23%) and received reduced-intensity conditioning (75%)...

Treatment related mortality (TRM) remains elevated in adult patients undergoing umbilical cord blood (UCB) transplantation, including an early rise in TRM suggestive of excessive toxicity associated with the standard myeloablative total body irradiation (TBI), fludarabine, and cyclophosphamide regimen. In an attempt to reduce regimen-related toxicity, we previously studied a modified myeloablative regimen with total body irradiation (1350 cGy) and fludarabine (160 mg/m(2)); TRM was decreased but neutrophil engraftment was suboptimal...

Autonomic dysreflexia is a dangerous elevation in blood pressure in people with spinal cord injury (SCI), produced by a spinally-mediated reflex activation of sympathetic vasoconstrictor neurones supplying skeletal muscle and the gut. Current dogma states that, apart from visceral inputs - such as those originating from a distended bladder or impacted colon - autonomic dysreflexia is triggered by noxious inputs below the lesion. However, while selective stimulation of small-diameter afferents in muscle or skin evokes a sustained increase in muscle sympathetic nerve activity and blood pressure, and a transient increase in skin sympathetic nerve activity and decrease in skin blood flow in able-bodied subjects, such noxious inputs have no effects on blood pressure and skin blood flow in SCI individuals...

BACKGROUND: Normal prenatal neurodevelopment follows stages that are potentially influenced by both chemical and psychosocial environments. Exposure to elevated manganese during this critically vulnerable period has been found to be neurotoxic. Independently, maternal prenatal depression has been associated with subsequent neurodevelopmental decrements in children. The association between child neurodevelopment and prenatal co-exposure to manganese and maternal depression has not been sufficiently studied...

Monozygotic twins with discordant karyotypes for trisomy 13 are rare. We report a case of a spontaneously conceived pregnancy who presented with first-trimester ultrasound finding of umbilical cord cyst and increased nuchal translucency in Twin A and no abnormalities in Twin B. Amniocentesis revealed 47,XY,+13 karyotype in Twin A and 46,XY karyotype in Twin B. Selective fetal reduction was performed for Twin A. Twin B was delivered at 32 weeks gestation with normal phenotype. Peripheral blood karyotype revealed 15% mosaicism for trisomy 13 and skin fibroblast revealed 46,XY karyotype...

OBJECTIVE: Testicular torsion (TT) refers to rotation of the testis and twisting of the spermatic cord. TT results in ischemia-reperfusion (I/R) injury involving increased oxidative stress, inflammation and apoptosis, and can even lead to infertility. The aim of this study was to investigate the effect of ozone therapy on testicular damage due to I/R injury in an experimental torsion model. MATERIALS AND METHODS: 24 male Sprague-Dawley rats were divided into 3 groups; sham-operated, torsion/detorsion (T/D), and T/D+ozone...

Chimeric antigen receptors (CARs) have been used to redirect the specificity of autologous T-cells against leukemia and lymphoma with promising clinical results.(1-3) Extending this approach to allogeneic T-cells is problematic as they carry a significant risk of graft-versus-host disease (GVHD). Natural killer (NK) cells are highly cytotoxic effectors, killing their targets in a non-antigen specific manner without causing GVHD. Cord blood (CB) offers an attractive, allogeneic, off-the-self source of NK cells for immunotherapy...

Hematopoietic stem cells (HSCs) were characterized by self-renewal and multilineage potential. Umbilical cord blood-derived (UCB) as an alternative source of HSCs is widely used especially in children for stem cells transplant (SCT). The main limitation in using UCB for transplantation especially in adults is low cell dose. To overcome this limitation besides using double dose UCB, ex vivo expansion is the most important way to increase cell number for transplantation. HSCs are mainly isolated using CD133 or CD34...
