Background: Multiple pregnancies occur more frequently in assisted reproductive technology (ART) compared to normal conception (NC). It is known that the risk of congenital malformations in a multiple pregnancy are higher than single pregnancy. The aim of this study is to compare congenital malformations in singleton infants conceived by ART to singleton infants conceived naturally. MATERIALS AND METHODS: In this historical cohort study, we performed a historical cohort study of major congenital malformations (MCM) in 820 singleton births from January 2012 to December 2014...

Vitamin D has been established as a key factor in the development of obesity through the vitamin D receptor (VDR). The aim of this study was to investigate the contribution of the VDR gene to obesity-related phenotypes in a population of Caucasian young adults. The study population consisted of 701 healthy Spanish young adults (mean age 20.41±2.48). Three single-nucleotide polymorphisms (SNPs) of VDR (TaqI, BsmI and FokI) were selected as genetic markers. Body composition measurements including weight, body mass index (BMI), fat mass (FM), percentage of fat mass (PFM), fat-free mass (FFM) and visceral fat level (VFL) were analysed...

Evidence on the relationship between the vitamin D pathway and outcomes in melanoma is growing, although it is not always clear. We investigated the impact of measured levels of sun exposure at diagnosis on associations of vitamin D receptor gene (VDR) polymorphisms and melanoma-death in 3336 incident primary melanoma cases. Interactions between six SNPs and a common 3' end haplotype were significant (p<0.05). These SNPs, and a haplotype, had a statistically significant association with survival among subjects exposed to high UVB in multivariable regression models, and exerted their effect in the opposite direction among those with low UVB...

Molecular mechanisms that define patterns of neuropeptide expression are essential for the formation and rewiring of neural circuits. The prodynorphin gene (PDYN) gives rise to dynorphin opioid peptides mediating depression and substance dependence. We here demonstrated that PDYN is expressed in neurons in human dorsolateral prefrontal cortex (dlPFC), and identified neuronal differentially methylated region in PDYN locus framed by CCCTC-binding factor binding sites. A short, nucleosome size human-specific promoter CpG island (CGI), a core of this region may serve as a regulatory module, which is hypomethylated in neurons, enriched in 5-hydroxymethylcytosine, and targeted by USF2, a methylation-sensitive E-box transcription factor (TF)...

Both vitamin D and collagen have roles in osteocartilaginous homeostasis. We evaluated the association between the circulating 25-hydroxyvitamin D (25(OH)D) type I and II collagen degradation products (CTx-I, and CTx-II), and four vitamin D receptor gene (VDR) polymorphisms, in Italian males affected by low back pain (LBP) due to herniation/discopathy and/or vertebral osteochondrosis. FokI, BsmI, ApaI, and TaqI VDR-polymorphisms were detected through PCR-restriction fragment length polymorphism (RFLP), and circulating 25(OH)D, CTx-I and CTx-II were measured by immunoassays in 79 patients (of which 26 had osteochondrosis) and 79 age-, sex- and body mass index (BMI)-matched healthy controls...

BACKGROUND: The disparity in prevalence of infectious diseases across the globe is common knowledge. Vitamin D receptor (VDR)-mediated toll-like receptor (TLR) 2/1 signaling produces antimicrobial peptides, which is critical as a first line of defense in innate immunity. Numerous studies disclosed the independent role of genetic polymorphisms in this pathway, vitamin D status or season and more recently epigenetics, as factors contributing to infectious disease predisposition. Few studies address the interaction between environment, genetics, and epigenetics...

Background -Endovascular treatment with mechanical thrombectomy (MT) is beneficial for acute stroke patients suffering a large vessel occlusion, though treatment efficacy is highly time-dependent. We hypothesized that interhospital transfer to endovascular-capable centers would result in treatment delays and worse clinical outcomes compared to direct presentation. Methods -STRATIS was a prospective, multicenter, observational, single-arm study of real-world MT for acute stroke due to anterior-circulation large vessel occlusion performed at 55 sites over 2 years, including 1000 patients with severe stroke and treated within 8 hours...

BACKGROUND: Various techniques have been used for wrap-clipping a ruptured, fusiform intracranial aneurysm. However, there is no available literature on use of the falx cerebri for wrap-clipping. OBJECTIVE: We present a review of the literature with an illustrative case, with a ruptured fusiform pericallosal artery aneurysm firmly attached to the lower edge of the falx cerebri and not amenable to endovascular intervention. METHODS: While the firm attachment between the inferior falx and the fusiform aneurysm was maintained, a section of the lower thinner part of the falx cerebri firmly attached to the aneurysm was dissected and wrapped around the fusiform aneurysm, stabilized with a fenestrated clip...

Two restriction-modification systems have been previously discovered in Thermus aquaticus YT-1. TaqI is a 263-amino acid (aa) Type IIP restriction enzyme that recognizes and cleaves within the symmetric sequence 5'-TCGA-3'. TaqII, in contrast, is a 1105-aa Type IIC restriction-and-modification enzyme, one of a family of Thermus homologs. TaqII was originally reported to recognize two different asymmetric sequences: 5'-GACCGA-3' and 5'-CACCCA-3'. We previously cloned the taqIIRM gene, purified the recombinant protein from Escherichia coli, and showed that TaqII recognizes the 5'-GACCGA-3' sequence only...

Nanopore sensors show great potential for rapid, single-molecule determination of DNA sequence information. Here, we develop an ionic current-based method for determining the positions of short sequence motifs in double-stranded DNA molecules with solid-state nanopores. Using the DNA-methyltransferase M.TaqI and a biotinylated S-adenosyl-l-methionine cofactor analogue we create covalently attached biotin labels at 5'-TCGA-3' sequence motifs. Monovalent streptavidin is then added to bind to the biotinylated sites giving rise to additional current blockade signals when the DNA passes through a conical quartz nanopore...
