To explore the association between DRD4 polymorphisms and schizophrenia risk, a meta-analysis was carried out with 41 case-control articles. Specifically, we included 28 articles (5,735 cases and 5,278 controls) that pertained to the 48 bp variable number tandem repeat (VNTR) polymorphism, nine articles (1,517 cases and 1,746 controls) that corresponded to the 12 bp tandem repeat (TR), six arti...

background: cytokines are cell signaling molecules which upon release by cells facilitate the recruitment of immune-modulatory cells towards the sites of inflammation. genetic variations in cytokine genes are shown to regulate their production and affect the risk of infectious as well as autoimmune diseases. intron-3 of interleukin-4 gene (il-4) harbors 70-bp variable number of tandem repeats (...
The Haloxylon genus belongs to the Amaranthaceae (formerly Chenopodiaceae) family. The small trees or shrubs in this genus are referred to as the King of psammophytic plants, and perform important functions in environmental protection, including wind control and sand fixation in deserts. To better understand these beneficial plants, we sequenced the chloroplast (cp) genomes of Haloxylon ammoden...
Chloroplast (cp) DNA genomes are traditional workhorses for studying the evolution of species and reconstructing phylogenetic relationships in plants. Species genus Castanea (chestnuts chinquapins) valued as a source nuts timber wherever they grow, chestnut hybrids common. We compared cp C. mollissima, seguinii, henryi, pumila. These ranged from 160,805 bp to 161,010 length, comprising pair inv...
ABSTRACT Objectives We determined the whole DNA sequences of plasmids carrying a rare extended-spectrum β-lactamase gene (blaTEM-61) to precisely understand spread resistance among nosocomial Serratia marcescens populations. Methods Twenty non-duplicate ceftazidime-resistant S. isolates (ceftazidime MICs, 32 >128 mg/L) collected over 1 year were pulsotyped and nucleotide blaTEM-61 its promoter ...
The nucleotide sequence of the long terminal repeat (LTR) of bovine leukemia virus, a unique oncogenic retrovirus of cattle, was determined. The LTR consisted of 530 base pairs (bp) with an inverted repeat of 6 bp at its 5' and 3' ends, flanked by a direct repeat of 6 bp of host cell origin. A tRNAPro binding site for minus-strand DNA synthesis followed the 5' LTR. The U3 region contained putat...
BACKGROUND We studied the repeatability of the ambulatory arterial stiffness index (AASI), which can be computed from 24-h blood pressure (BP) recordings as unity minus the regression slope of diastolic on systolic BP. METHODS One hundred and fifty-two hypertensive outpatients recruited in Nijmegen (mean age = 46.2 years; 76.3% with systolic and diastolic hypertension) and 145 patients enroll...
An inverted sea urchin histone gene sequence with breakpoints between TATA boxes and mRNA cap sites.
A sea urchin histone gene fragment containing inverted regions of the normal repeat has been cloned in pBR322. Restriction enzyme mapping and homoduplex analysis of this fragment indicate that the H1-H4 spacer of one repeat is situated alongside the inverted H2A-H1 spacer of another repeat. The site of the breakpoint has been sequenced and compared with homologous stretches of the normal repeat...
The two most consistent features of the diseases caused by trinucleotide repeat expansion-neuropsychiatric symptoms and the phenomenon of genetic anticipation-may be present in forms of dementia, hereditary ataxia, Parkinsonism, bipolar affective disorder, schizophrenia and autism. To identify candidate genes for these disorders, we have screened human brain cDNA libraries for the presence of g...
