Previous studies of repeat induced point mutation (RIP) have typically involved gene-size duplications resulting from insertion of transforming DNA at ectopic chromosomal positions. To ascertain whether genes in larger duplications are subject to RIP, progeny were examined from crosses heterozygous for long segmental duplications obtained using insertional or quasiterminal translocations. Of 17...
The complete nucleotide sequence of the mt (mitochondrial) and cp (chloroplast) genomes of the unicellular green alga Ostreococcus tauri has been determined. The mt genome assembles as a circle of 44,237 bp and contains 65 genes. With an overall average length of only 42 bp for the intergenic regions, this is the most gene-dense mt genome of all Chlorophyta. Furthermore, it is characterized by ...
Urethralduplication is a rare condition occurs as a congenital malformation either independently or in the setting of other congenital malformations such as caudal duplication syndrome. Its prevalence becomes even rarer if it manifests as two side-by-side tracts in coronal plan.Nonetheless, we introduce a unique presentation of complete coronal urethral duplication accompanied by astoundin...
Portapres is a noninvasive, beat-to-beat finger blood pressure (BP) monitor that has been shown to accurately estimate 24-hour intra-arterial BP at normal and high BPs. However, no information is available on the ability of this device to accurately track ambulatory BP variability. In 20 ambulatory normotensive and hypertensive subjects, we measured 24-hour BP by Portapres and through a brachia...
BACKGROUND The variability of blood pressure (BP) makes any single measurement a poor indicator of a patient's true BP. Multiple studies have confirmed the superiority of ambulatory BP measurements over clinic BP measurements in predicting cardiovascular risk; however, this method presents the problem of patient acceptance as it causes frequent arm discomfort and sleep disturbance. We hypothesi...
Simian virus 40 (SV40) DNAs in brain tissue and peripheral blood mononuclear cells (PBMCs) of eight simian immunodeficiency virus-infected rhesus monkeys with SV40 brain disease were analyzed. We report the detection, cloning, and identification of five new SV40 strains following a quadruple testing-verification strategy. SV40 genomes with archetypal regulatory regions (containing a duplication...
The northern pike is the most frequently studied member of the Esociformes, the closest order to the diverse and economically important Salmoniformes. The ancestor of all salmonids purportedly experienced a whole-genome duplication (WGD) event, making salmonid species ideal for studying the early impacts of genome duplication while complicating their use in wider analyses of teleost evolution. ...
BACKGROUND A hypertensive response after ischemic stroke is frequent, yet its pathophysiology is unknown. Mechanisms related to local ischemic damage, major vascular occlusion, and psychological stress due to acute illness have been proposed. We assessed the natural course of blood pressure (BP) within the first 24 h in groups of ischemic stroke patients with different characteristics. We hypot...
Gene duplication is a characteristic feature of eukaryotic genomes. Here we investigated the role of gene duplication in the evolution of the gloverin family of antibacterial genes (Bmglv1, Bmglv2, Bmglv3, and Bmglv4) in Bombyx mori. We observed the following two significant changes during the first duplication event: (i) loss of intronV, located in the 3'-untranslated region (UTR) of the ances...
duplication anomalies are quite common with ureteral duplication anomalies being the most frequent. despite the relatively frequent incidence of a horseshoe kidney and duplication anomalies in any individual patient, the combination of horseshoe kidney and bilateral ureteric duplication is a very rare entity and very few cases have been reported to date. we present a case of a patient with nove...
