OBJECTIVE: Segmental instability is traditionally investigated with flexion and extension (F/E) X-rays. We sought to determine whether motion between upright and supine (U/S) views can serve as an alternative sensitive diagnostic tool that predicts similar outcomes. METHODS: Ambispective collection of data was performed for 222 consecutive patients that underwent transforaminal lumbar interbody fusion (TLIF). Patients were divided into either Group 1 (≥3 mm spondylolisthesis difference between F/E X-rays) or Group 2 (≥3 mm spondylolisthesis difference between U/S imaging and otherwise not meeting Group 1 criteria)...

BACKGROUND: The impact of nutrition on the evolution towards type 2 diabetes has recently received increasing attention because of the effect on chromatin structure and gene expression. PURPOSE: Evaluate the effect of high-fat diet on chromatin remodelling and expression of Ped/Pea-15, a gene commonly overexpressed in individuals at risk of type 2 diabetes. METHODS: We used mouse and cell models to investigate Ped/Pea-15 transcriptional regulation by high-fat diet and glucose, respectively...

One of the major causes of tooth loss is chronic inflammation of the periodontium, the tissues surrounding the tooth. Amelotin (AMTN) is a tooth enamel protein which is expressed in maturation-stage ameloblasts and also in the internal basal lamina of junctional epithelium, a unique epithelial structure attached to the tooth surface which protects against the constant microbiological challenge to the periodontium. Localization of AMTN suggests that its function could be involved in the dentogingival attachment...

Transcribed-ultraconserved regions (T-UCRs), which contain conserved sequences with 100% identity across human, rat and mouse species, are a novel category of functional RNAs. The human transformer 2β gene ( TRA2B ) encodes a UCR that spans exon 2 (276 bp) and its neighboring introns. Among five spliced RNA variants ( TRA2β1-5 ) transcribed from the TRA2B gene, only TRA2β4 contains the conserved exon 2. TRA2β4 is overexpressed in colon cancer cells and accelerates cell growth by blocking the transcription of CDKN1A ...

Genetic taxonomic assignment can be more sensitive than morphological taxonomic assignment, particularly for small, cryptic or rare species. Sequence processing is essential to taxonomic assignment, but can also produce errors because optimal parameters are not known a priori. Here, we explored how sequence processing parameters influence taxonomic assignment of 18S sequences from bulk zooplankton samples produced by 454 pyrosequencing. We optimized a sequence processing pipeline for two common research goals, estimation of species richness and early detection of aquatic invasive species (AIS), and then tested most optimal models' performances through simulations...

Bullous pemphigoid (BP) is a blistering autoimmune disease mainly observed in elderly patients. Several triggers are known for this autoimmune disease and some drugs are known to be a cause of BP. However, there are only few case reports on the induction of BP under adalimumab therapy. Other autoimmune diseases, such as lupus erythematosus, are also known to occur under TNF inhibition. Here, we report on an 81-year-old patient who received adalimumab for ulcerative colitis and subsequently developed BP. Other causes of BP (tumors, other drugs, viral or toxoplasma infections) were excluded...

BACKGROUND: Many patients are diagnosed with hypertension each year, making rapid and effective control of blood pressure (BP) crucial. Appropriate first-line treatment is important, and special attention should be paid to the positive effects of lowering BP early. Perindopril 3.5 mg/amlodipine 2.5 mg (P3.5/A2.5) is a single-pill combination suitable for first-line use. The doses of each component of the single-pill combination were selected for a first-line setting. OBJECTIVE: To investigate the effectiveness of the P3...

OBJECTIVE: Rectangular (cylindrical) cuffs and bladders are currently used for blood pressure (BP) measurement at the upper arm. However, large arms have a troncoconical shape, which make cylindrical cuffs potentially unsuitable. Aim of this study was to investigate the effect of the shape of the cuff on BP measurement in very obese participants. METHODS: In 33 participants with upper arm mid-circumference at least 42 cm and 33 participants of control, cylindrical and troncoconical cuffs of appropriate size were compared...

BACKGROUND: Epidemiologic evidence suggests that low-fat dairy consumption may lower risk of hypertension. Dairy products may be distinctly linked to health, because of differences in nutritional composition, but little is known about specific nutrients that contribute to the dairy-blood pressure (BP) association, nor to underlying kidney function. METHODS: We examined cross-sectional associations to BP of dairy product intakes, total and by type, from the INTERnational study on MAcro/micronutrients and blood Pressure (INTERMAP) including 2694 participants aged 40-59 years from the UK and the USA...

INTRODUCTION: Higher levels of total testosterone and lower levels of sex hormone-binding globulin (SHBG) have been associated with increased blood pressure (BP) in women with an inverse association between total testosterone and BP among men. Fewer studies have examined associations with 24-h ambulatory blood pressure (ABP), blunted nocturnal BP decline or the role of dehydroepiandrosterone sulfate (DHEAS), a precursor to androgens. METHODS: Baseline blood samples were assayed for 229 normotensive men (≥50 years) and women (≥55 years) participating in the VITamin D and OmegA-3 TriaL...

BACKGROUND: Self-measurement of blood pressure (BP) is increasingly being used for the diagnosis of hypertension and to monitor BP at home. Whenever compared with ambulatory BP measurements, home BP values are frequently higher and less predictive for incident cardiovascular events. We hypothesized that this could be caused by a pressor response elicited by the self-measurement of BP. METHODS: A total of 50 patients (mean age 62.0 ± 11.2 years, 44% women) were included, 25 with and 25 without at least 10/5 mmHg higher home BP compared with daytime ambulatory BP...

The Papillomaviridae is a family of small, non-enveloped viruses with double-stranded DNA genomes of 5 748 to 8 607 bp. Their classification is based on pairwise nucleotide sequence identity across the L1 open reading frame. Members of the Papillomaviridae primarily infect mucosal and keratinised epithelia, and have been isolated from fish, reptiles, birds and mammals. Despite a long co-evolutionary history with their hosts, some papillomaviruses are pathogens of their natural host species. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Papillomaviridae, which is available at http://www...

Pseudomonas fluorescens KLR101 was found to be capable of producing polyhydroxyalkanoate (PHA) using various sugars and fatty acids with carbon numbers ranging from 2 to 6. PHA granules mainly consisted of poly(3-hydroxybutyrate) homopolymer and/or poly(3-hydroxybutyrate- co -3-hydroxyvalerate) copolymer. Genomic DNA of P. fluorescens was fractionated and cloned into a lambda library, in which a 5.8-kb fragment hybridized to a heterologous phaC probe from Ralstonia eutropha was identified. In vivo expression in Klebsiella aerogenes KC2671 (pUMS), restriction mapping, Southern hybridization experiments, and sequencing data revealed that PHA biosynthesis by P...

The synthesis of designer DNA requires an approach where the user can determine both the sequence and the number of nucleobases. The protocol outlined here describes an enzymatic method for the synthesis of long repeat-sequence DNA. The method utilizes a PCR-based approach; starting with short oligo-seeds, c.a. 20 bp, bearing a minimum of two repeating units of >8 bp sequences. During each heat-cool cycle, the oligo-seeds reanneal imperfectly leaving an overhang, which is then extended by the polymerase...

HKT transporters which mediate Na+ -specific transport or Na+ -K+ co-transport, play an important role in protecting plants from salinity stress by preventing Na+ -over-accumulation in leaves. In this work, a 1508-bp genomic fragment upstream of the TmHKT1;4-A1 translated sequence from Triticum monococcum has been isolated, cloned, and designated as the ''PrTmHKT1;4-A1'' promoter. Sequence analysis of ''PrTmHKT1;4-A1'' revealed the presence of cis-regulatory elements which could be required for abiotic stress and abscisic acid (ABA) responsiveness...
