Effect on blood pressure of daily lemon ingestion and walking.

Background. Recent studies suggest that the daily intake of lemon (Citrus limon) has a good effect on health, but this has not been confirmed in humans. In our previous studies, it was observed that people who are conscious of their health performed more lemon intake and exercise. An analysis that took this into account was required. Methodology. For 101 middle-aged women in an island area in Hiroshima, Japan, a record of lemon ingestion efforts and the number of steps walked was carried out for five months...

Multiplicative update rules for concurrent nonnegative matrix factorization and maximum margin classification.

The state-of-the-art classification methods which employ nonnegative matrix factorization (NMF) employ two consecutive independent steps. The first one performs data transformation (dimensionality reduction) and the second one classifies the transformed data using classification methods, such as nearest neighbor/centroid or support vector machines (SVMs). In the following, we focus on using NMF factorization followed by SVM classification. Typically, the parameters of these two steps, e.g., the NMF bases/co...

Is confirmatory testing of Roche cobas 4800 CT/NG test Neisseria gonorrhoeae positive samples required? Comparison of the Roche cobas 4800 CT/NG test with an opa/pap duplex assay for the detection of N gonorrhoeae.

Recently marketed nucleic acid amplification tests (NAAT) for the detection of Neisseria gonorrhoeae (NG) have improved specificity over previous generation assays. A study to assess the necessity for confirmation of Roche cobas 4800 NG positive samples was undertaken by the Public Health Wales Microbiology Molecular Diagnostic Unit in Cardiff.

Update on the Guytonian view of hypertension.

Dr Arthur Guyton hypothesized that the capacity of the kidney to excrete sodium ultimately dictates long-term changes in blood pressure. This model has had a profound influence on our understanding of blood pressure regulation. The goal of this article is to review a selection of classic studies and highlight more recent molecular studies supporting or refuting the Guyton model of blood pressure regulation.

Genome sequencing and comparative analysis of three Chlamydia pecorum strains associated with different pathogenic outcomes.

Chlamydia pecorum is the causative agent of a number of acute diseases, but most often causes persistent, subclinical infection in ruminants, swine and birds. In this study, the genome sequences of three C. pecorum strains isolated from the faeces of a sheep with inapparent enteric infection (strain W73), from the synovial fluid of a sheep with polyarthritis (strain P787) and from a cervical swab taken from a cow with metritis (strain PV3056/3) were determined using Illumina/Solexa and Roche 454 genome sequ...

Metallographic Assessment of Al-12Si High-Pressure Die Casting Escalator Steps.

A microstructural characterization study was performed on high-pressure die cast specimens extracted from escalator steps manufactured from an Al-12 wt.% Si alloy designed for structural applications. Black and white, color light optical imaging and scanning electron microscopy techniques were used to conduct the microstructural analysis. Most regions in the samples studied contained globular-rosette primary α-Al grains surrounded by an Al-Si eutectic aggregate, while primary dendritic α-Al grains were pr...

Pressure-relieving devices for treating heel pressure ulcers.

Pressure ulcers are areas of localised damage to the skin and underlying tissue caused by pressure or shear. Pressure redistribution devices are used as part of the treatment to reduce the pressure on the ulcer. The anatomy of the heel and the susceptibility of the foot to vascular disease mean that pressure ulcers located there require a particular approach to pressure relief.

Serotonin and Sensory Nerves: Meeting in the Cardiovascular System.

Blood pressure regulation by 5-HT has proven to be a complex story to unravel. The work by Cuesta et al., in this issue of Vascular Pharmacology adds another layer of complexity by providing sound in vivo data that 5-HT, through the 5-HT7 receptor, can inhibit the vasodepressor actions of the sensory nervous system and thereby promote blood pressure maintenance. This interaction of 5-HT with the sensory nervous system is inhibitory, whereas 5-HT is understood to be stimulatory in other systems. Moreover, ac...

Comparison of the Gen-Probe Aptima HIV-1 and Abbott HIV-1 qualitative assays with the Roche Amplicor HIV-1 DNA assay for early infant diagnosis using dried blood spots.

The current gold standard for infant diagnosis of HIV-1 is the Roche Amplicor Qualitative DNA assay, but it is being phased out.

Effects of cyclic static stretch on fatigue recovery of triceps surae in female basketball players.

Static stretch is a safe and feasible method which usually is used before exercise to avoid muscle injury and to improve muscle performance. The purpose of this study was to determine the effects of cyclic static stretch (CSS) on fatigue recovery of triceps surae (TS) in female basketball players. Nine athlete volunteers between 20 and 30 years participated in this study containing two sessions. After warm-up a pressure cuff was fastened above the knee joint and its pressure was increased to 140 mmHg. The s...

5-Fluorouracil for glaucoma surgery.

Trabeculectomy is performed as a treatment for many types of glaucoma in an attempt to lower the intraocular pressure. The surgery involves creating a channel through the sclera, through which intraocular fluid can leave the eye. If scar tissue blocks the exit of the surgically created channel, intraocular pressure rises and the operation fails. Antimetabolites such as 5-Fluorouracil (5-FU) are used to inhibit wound healing to prevent the conjunctiva scarring down on to the sclera. This is an update of a Co...

Role of turgor pressure in endocytosis in fission yeast.

Yeast and other walled cells possess high internal turgor pressure that allows them to grow and survive in the environment. This turgor pressure however may oppose the invagination of the plasma membrane needed for endocytosis. Here, we study the effects of turgor pressure on endocytosis in the fission yeast Schizosaccharomyces pombe by time lapse imaging of individual endocytic sites. Decreasing effective turgor pressure by addition of sorbitol to the media significantly accelerates early steps in the endo...

Python-based geometry preparation and simulation visualization toolkits for STEPS.

STEPS is a stochastic reaction-diffusion simulation engine that implements a spatial extension of Gillespie's Stochastic Simulation Algorithm (SSA) in complex tetrahedral geometries. An extensive Python-based interface is provided to STEPS so that it can interact with the large number of scientific packages in Python. However, a gap existed between the interfaces of these packages and the STEPS user interface, where supporting toolkits could reduce the amount of scripting required for research projects. Thi...

Day-to-Day Variability in Home Blood Pressure Is Associated With Cognitive Decline: The Ohasama Study.

Although an association between high blood pressure and cognitive decline has been reported, no studies have investigated the association between home blood pressure and cognitive decline. Home blood pressure measurements can also provide day-to-day blood pressure variability calculated as the within-participant SD. The objectives of this prospective study were to clarify whether home blood pressure has a stronger predictive power for cognitive decline than conventional blood pressure and to compare the pre...

Central blood pressure: current evidence and clinical importance.

Pressure measured with a cuff and sphygmomanometer in the brachial artery is accepted as an important predictor of future cardiovascular risk. However, systolic pressure varies throughout the arterial tree, such that aortic (central) systolic pressure is actually lower than corresponding brachial values, although this difference is highly variable between individuals. Emerging evidence now suggests that central pressure is better related to future cardiovascular events than is brachial pressure. Moreover, a...

Pressure Difference Between the Anterior Chamber and the Vitreous Cavity in Eyes with Pupillary Block.

Abstract Purpose: The purpose of this study was to measure the pressure difference between the anterior chamber (AC) and the vitreous cavity (VC) in eyes with and without pupillary block. Materials and methods: Seven vitrectomized porcine eyes were used. Infusion pressures of 10-80 mmHg were generated with a vented gas forced infusion system. Measurements of pressure were obtained with digital manometry connected to 25-gauge catheters from the AC and VC simultaneously. After increasing AC pressure to each...

Protocol Independent Adaptive Route Update for VANET.

High relative node velocity and high active node density have presented challenges to existing routing approaches within highly scaled ad hoc wireless networks, such as Vehicular Ad hoc Networks (VANET). Efficient routing requires finding optimum route with minimum delay, updating it on availability of a better one, and repairing it on link breakages. Current routing protocols are generally focused on finding and maintaining an efficient route, with very less emphasis on route update. Adaptive route update ...

Implicit Incompressible SPH.

We propose a novel formulation of the projection method for Smoothed Particle Hydrodynamics (SPH). We combine a symmetric SPH pressure force and an SPH discretization of the continuity equation to obtain a discretized form of the pressure Poisson equation (PPE). In contrast to previous projection schemes, our system does consider the actual computation of the pressure force. This incorporation improves the convergence rate of the solver. Furthermore, we propose to compute the density deviation based on velo...
