There is a range of risk factors that can lead to peripheral intravenous (IV) cannula failure, and several failed cannulation attempts can result in the patient experiencing increased pain, discomfort and delays in receiving IV therapy. The Vessel Health and Preservation (VHP) framework is a tool that can be used to improve clinical decision-making and the patient experience in relation to vascular access and IV therapy. Use of the VHP framework can ensure the right vein and right vascular access device (VAD) is selected at the right time for each patient...

In the paper the short- and long-term glycaemic response after 4 diet programmes was evaluated. Each diet programme was alternatively administered to 6 healthy cats for 30 days. At the end of each period cats were weighed and underwent blood sampling for glucose and fructosamine determination. Glycaemia was measured every 2 hours for 24 hours using an automated glucometer. Very high protein level and low starch (VHP÷LS) and high protein and moderate starch level (HP÷LS) diets showed glucose (Mean and Peak) and fructosamine values signi cantly lower compared to the moderate protein and high starch diets (MP/HS)...

Bacillus and Clostridium species form spores, which pose a challenge to the food industry due to their ubiquitous nature and extreme resistance. Pressurization at <300 MPa triggers spore germination by activating germination receptors (GRs), while pressurization at >300 MPa likely triggers germination by opening dipicolinic acid (DPA) channels present in the inner membrane of the spores. In this work, we expose spores of Bacillus licheniformis, a species associated with food spoilage and occasionally with food poisoning, to high pressure (HP) for holding times of up to 2 h...

Vascular access is an important component of health care but is not without associated risks, some of which can be life-threatening. The Vessel Health and Preservation (VHP) framework was developed with the intention of providing frontline staff with a resource to assist in assessing and selecting the best vascular access device to meet individual patient needs and to preserve veins for future use. This article examines the impact of the introduction of the framework into a haematology ward in an acute hospital in the North West of England during a 3-month pilot study...

The effects of ethylene oxide (EO), vaporized hydrogen peroxide (VHP), gamma (γ) radiation, and electron-beam (E-beam) on the physiochemical and morphological properties of medical device polymers are investigated. Polymers with ether, carbonate, carboxylic acid, amide and ester functionalities are selected from a family of poly(ethylene glycol) (PEG) containing tyrosine-derived polycarbonates (TyrPCs) to include slow, medium, fast, and ultrafast degrading polymers. Poly(lactic acid) (PLA) is used for comparison...

Simulation of the electromagnetic response of the human body relies upon efficient computational models. The objective of this paper is to describe a new platform-independent and computationally-efficient full-body electromagnetic model, the Visible Human Project® (VHP)-Female v.3.0 and to outline its distinct features. We also report model performance results using two leading commercial electromagnetic antenna simulation packages: ANSYS HFSS and CST MICROWAVE STUDIO®.

This retrospective study aimed to evaluate, through an ad hoc 17-item tool, the Pulmonary Rehabilitation Decisional Score (PRDS), the priority access to PR prescription by respiratory specialists. The PRDS, scoring functional, clinical, disability, frailty, and participation parameters from 0 = low priority to 34 = very high priority for PR access, was retrospectively calculated on 124 specialist reports sent to the GP of subjects (aged 71 ± 11 years, FEV1%  51 ± 17) consecutively admitted to our respiratory outpatient clinic...

JNK proteins are conserved stress-activated MAP kinases. In C. elegans, the JNK-homolog KGB-1 plays essential roles in protection from heavy metals and protein folding stress. However, the contributions of KGB-1 are age-dependent, providing protection in larvae, but reducing stress resistance and shortening lifespan in adults. Attenuation of DAF-16 was linked to the detrimental contributions of KGB-1 in adults, but its involvement in KGB-1-dependent protection in larvae remains unclear. To characterize age-dependent contributions of KGB-1, we used microarray analysis to measure gene expression following KGB-1 activation either in developing larvae or in adults, achieved by knocking down its negative phosphatase regulator vhp-1...

The thermal decomposition of syn-ethanal-oxide (syn-CH3CHOO) through vinyl hydrogen peroxide (VHP) leading to hydroxyl radical is characterized using a modification of the HEAT thermochemical protocol. The isomerization step of syn-CH3CHOO to VHP via a 1,4 H-shift, which involves a moderate barrier of 72 kJ/mol, is found to be rate determining. A two-dimensional master equation approach, in combination with semi-classical transition state theory, is employed to calculate the time evolution of various species as well as to obtain phenomenological rate coefficients...

OBJECTIVES: To evaluate the effectiveness of CT before TAVI using variable helical pitch (VHP) scanning and its diagnostic performance for coronary artery disease (CAD). METHODS: Sixty patients (84.4 ± 4.6 years) scheduled for TAVI underwent CT using VHP scanning with the contrast material (CM) volume calculated as scanning time × weight [kg] × 0.06 mL. Retrospective electrocardiography (ECG)-gated scanning was utilized to examine the thorax, and non-ECG-gated scanning of the abdomen immediately followed...

Ozonolysis of alkenes is an important nonphotolytic source of hydroxl radicals in the troposphere. The reaction proceeds through cycloaddition and subsequent decomposition to a carbonyl oxide, known as Criegee intermediates. Ozonolysis of alkene releases about 50 kcal/mol excess energy to form highly energized Criegee molecules, which can be stabilized and undergo further reaction or dissociate to OH+vinoxy products. The dissociation dynamics of partially stabilized Criegee (syn-CH3CHOO) has been thoroughly studied recently, in which the molecules dissociate by first isomerizing to vinyl hydroperoxide (VHP)...

Synthetic peptides that contain backbone modifications but nevertheless adopt folded structures similar to those of natural polypeptides are of fundamental interest and may provide a basis for biomedical applications. Such molecules can, for example, mimic the ability of natural prototypes to bind to specific target macromolecules but resist degradation by proteases. We have previously shown that oligomers containing mixtures of α- and β-amino acid residues ("α/β-peptides") can mimic the α-helix secondary structure, and that properly designed α/β-peptides can bind to proteins that evolved to bind to α-helical partners...

Glucagon-like peptide-1 (GLP-1) is currently one of the most promising biological systems for the development of effective obesity pharmacotherapies. Long-acting GLP-1 analogs potently reduce food intake and body weight, and recent discoveries reveal that peripheral administration of these drugs reduces food intake largely through humoral pathways involving direct action on brain GLP-1 receptors (GLP-1R). Thus, it is of critical importance to understand the neural systems through which GLP-1 and long-acting GLP-1 analogs reduce food intake and body weight...

A quantitative risk analysis (QRA) regarding dangerous goods vehicles (DGVs) running through road tunnels was set up. Peak hourly traffic volumes (VHP), percentage of heavy goods vehicles (HGVs), and failure of the emergency ventilation system were investigated in order to assess their impact on the risk level. The risk associated with an alternative route running completely in the open air and passing through a highly populated urban area was also evaluated. The results in terms of social risk, as F/N curves, show an increased risk level with an increase the VHP, the percentage of HGVs, and a failure of the emergency ventilation system...
