The role of Helicobacter pylori DnaA domain I in orisome assembly on a bipartite origin of chromosome replication.

The main roles of the DnaA protein are to bind the origin of chromosome replication (oriC), to unwind DNA and to provide a hub for the step-wise assembly of a replisome. DnaA is composed of four domains, with each playing a distinct functional role in the orisome assembly. Out of the four domains, the role of domain I is the least understood and appears to be the most species-specific. To better characterise H. pylori DnaA domain I, we have constructed a series of DnaA variants and studied their interaction...

Why Knowing Healthy Controls Matters.

Although healthy volunteers often serve as controls or primary participants in neuroscience research, they are usually less rigorously screened than patients, which can have far-reaching implications for interpretation of study results. Although this issue has long been recognized, it is rarely discussed in the research literature. This article examines how the rigorous screening and characterization of healthy volunteers is key for quality research.

'Becoming-with' a repeat healthy volunteer: Managing and negotiating trust among repeat healthy volunteers in commercial clinical drug trials.

Recent sociological research has raised important sociological and ethical questions about the role of financial rewards in terms of healthy volunteer involvement in clinical trials. Research suggests that it would be parochial to assume financial rewards alone are sufficient to explain repeat healthy volunteering. This paper explores other factors that might explain repeat healthy volunteering behaviours in phase I clinical drug trials. Drawing on qualitative research with healthy volunteers, the paper arg...

Evaluation of pharmacokinetics and safety with bioequivalence of Amlodipine in healthy Chinese volunteers: Bioequivalence Study Findings.

Amlodipine, a main series of L-type calcium channel blockers (CCBs), exerts potent antihypertensive effects. The aim of this trial was to explore the pharmacokinetics (PK) and safety with bioequivalence of orally administered Amlodipine provided by two sponsors in healthy volunteers (HVs).

Increased systemic endothelial-dependent microvascular reactivity after ingestion of a high-carbohydrate snack in young, healthy volunteers.

This study evaluated the acute effect of a high-carbohydrate snack (HCS) on systemic microvascular function of healthy, young volunteers, using laser speckle contrast imaging (LSCI).

Early and late effects of remote ischemic preconditioning on spirometry and gas exchange in healthy volunteers.

Remote ischemic preconditioning (RIP) may protect remote organs from ischemia-reperfusion-injury (IRI) in surgical and non-surgical patients. There are few data available on RIP and lung function, especially not in healthy volunteers. The null-hypothesis was tested that RIP does not have an effect on pulmonary function when applied on healthy volunteers that were breathing spontaneously and did not experience any intervention. After approval of the Ethics Committee and informed consent of the study subjects...

Cefuroxime pharmacokinetics and pharmacodynamics for intravenous dosage regimens with 750 mg or 1500 mg doses in healthy young volunteers.

Cefuroxime is an important antibiotic to treat several serious infections. Rapid elimination through the kidneys and the variation in MICs of various susceptible pathogens such as and give rise to dosing issues, especially in otherwise healthy patients. To investigate the probability of target attainment (PTA) for obtaining the optimal dosage regimens for cefuroxime in healthy young people. Two weeks apart 750 and 1500 mg cefuroxime were administered as an intravenous bolus to 20 healthy volunteers (mea...

The gut microbiome in epilepsy.

The close relationship between epilepsy and autoimmune diseases and the fact that the cause of epilepsy is idiopathic in 60% of cases suggest that intestinal microbiota may play a role in the etiology of epilepsy. In this study, we analyzed and compared the intestinal microbiota composition of patients with idiopathic focal epilepsy (n = 30) and healthy volunteer group (n = 10) by 16s ribosomal DNA sequencing. Proteobacteria phylum was found to be higher in patients with epilepsy (25.4%) than in hea...

Variability of CD4+ cell counts in HIV-1 uninfected volunteers who are eligible for a Phase I HIV vaccine study.

Vaccines and biologics containing CD4 molecules or HIV-1 gp120 might induce antibodies targeting CD4. We evaluated temporal variability of CD4 levels in healthy volunteers to quantify declines that could indicate true adverse events.

Bioavailability and safety of diazepam intranasal solution compared to oral and rectal diazepam in healthy volunteers.

The study assesses the bioavailability of diazepam after intranasal administration (diazepam nasal spray) in healthy volunteers. Comparative agents were diazepam rectal gel, which served as the regulatory reference product; and oral diazepam, a product with decades of clinical use. Tolerability of diazepam nasal spray was also assessed.

The potential application of human PIG-A assay on Azathioprine treated inflammatory bowel disease patients.

The rodent Pig-a assay has been used extensively as a potential regulatory assay for evaluating the in vivo mutagenicity of test substances. Although the assay can be conducted in different mammalian species, there have been only a few reports describing its use in humans, and rarely in genotoxicant-exposed human populations. In this study, PIG-A mutation frequencies (MFs) were evaluated in 36 Azathioprine (AZA) (human carcinogen) treated inflammatory bowel disease (IBD) patients and 36 healthy volunteers. ...

Markers of systemic inflammation in response to osmotic stimulus in healthy volunteers.

Hyperosmolality, osmotic stimulus or stress results in vasopressin release. Animal and human in vitro studies have shown that inflammatory parameters such as interleukin-8 (IL-8) and tumour necrosis factor-α (TNF-α) increase in parallel in the central nervous system and bronchial, corneal or intestinal epithelial cell lines in response to osmotic stimulus. Whether osmotic stimulus directly causes a systemic inflammatory response in humans is unknown. We therefore investigated the influence of osmotic stim...

Agreement between clinical and non-clinical digital manometer for assessing maximal respiratory pressures in healthy subjects.

Measurement of respiratory muscles strength such as maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) are used to detect, diagnose and treat respiratory weakness. However, devices used for these measurements are not widely available and are costly. Currently, the use of a digital manometer is recommended. In industry, several inexpensive devices are available, but these have not been validated for clinical use. Our objective was to determine the agreement between maximal respiratory p...

Safety, Tolerability and Pharmacokinetics of Single Dose Polyethylene Glycolated Exenatide Injection (PB-119) in Healthy Volunteers.

Exenatide promotes insulin secretion and inhibits postprandial glucagon secretion. Polyethylene glycolated exenatide injection (PB-119), a derivative obtained by modification of exenatide, is more stable in metabolic behavior than exenatide in vivo. Our study aimed to evaluate the safety, tolerability and pharmacokinetic characteristics of polyethylene glycolated exenatide as a single subcutaneous injection in healthy volunteers.

Effect of pituitary adenylate cyclase-activating polypeptide-27 on cerebral hemodynamics in healthy volunteers: a 3T MRI study.

Pituitary adenylate cyclase-activating polypeptide (PACAP) has emerged as an important signaling peptide in migraine pathogenesis. Recently, we have shown that the less-abundant PACAP isoform, PACAP27, induced migraine and headache in patients equipotently to PACAP38. The present study examined the effect of PACAP27 on cerebral hemodynamics in healthy volunteers using high resolution magnetic resonance angiography (MRA). Eighteen healthy volunteers received infusion of PACAP27 (10 pmol/kg/min) or placebo ...

The viewing of a 'Bloodcurdling' horror movie increases platelet reactivity: A randomized cross-over study in healthy volunteers.

Epidemiological studies have suggested an increased risk of cardiovascular events (CVE) during acute stressful and/or frightful moments. A possible explanation for this could be an effect of acute stress on hemostasis. A recent study demonstrated an increase in factor VIII after watching a horror movie. Primary hemostasis, however, is thought to play a more prominent role in the etiology of CVE. The objective of this study was therefore to assess the influence of viewing a 'bloodcurdling' horror movie on pl...
