Upon bacterial infection one of the defense mechanisms of the host is the withdrawal of essential metal ions, in particular iron leading to "nutritional immunity". However, bacteria have evolved strategies to overcome iron starvation, e.g. by stealing iron from the host or other bacteria by specific iron chelators with high binding affinity. Fortunately, these complex interactions between host and pathogen regarding metal homeostasis provide several opportunities for interception and thus allow the development of novel antibacterials...

BACKGROUND: The possibility of coronary steal through an arteriovenous fistula (AVF) in hemodialysis (HD) patients with coronary artery bypass grafts (CABGs) using an ipsilateral internal thoracic artery (ITA) has been suggested. In order to define the significance of such a possibility, we analyzed cardiac events and mortality risk in patients in relation to AVF flow. METHODS: A retrospective cohort study was performed on prevalent HD patients from a single center...

OBJECTIVE: Ipsilateral arteriovenous fistula (AVF) may cause symptoms of coronary steal in patients who had undergone coronary artery bypass graft (CABG) using internal thoracic artery. The purpose of this study was to evaluate the adverse effects of ipsilateral AVF to CABG, including the incidence of coronary steal, and to analyze the risk factors for coronary steal. METHODS: Between 2000 and 2013, a total of 25 patients undergoing hemodialysis via upper extremity AVF, ipsilateral to the preexisting CABG, were reviewed retrospectively...

We presented a case of subclavian steal syndrome which has been evaluated and treated quantitatively by using fractional flow reserve technique. Treatment strategy to resolve symptoms of angina in patients with steal syndrome is controversial. Quantitative evaluation should direct choice of treatment strategy.

The clinical benefits of using the left internal mammary artery (LIMA) to bypass the left anterior descending artery are well established making it the most frequently used conduit for coronary artery bypass surgery (CABG). Coronary subclavian steal syndrome (CSSS) occurs during left arm exertion when (1) the LIMA is used during bypass surgery and (2) there is a high grade (≥75%) left subclavian artery stenosis or occlusion proximal to the ostia of the LIMA resulting in "stealing" of the myocardial blood supply via retrograde flow up the LIMA graft to maintain left upper extremity perfusion...

Atherosclerotic subclavian artery disease is detected in about 5% of patients referred for coronary artery bypass (CABG) surgery. The internal mammary artery, a branch of the subclavian artery, is the most frequently utilized graft to restore coronary circulation because of its longevity. Stenosis or occlusion of the subclavian artery can cause retrograde blood flow in the ipsilateral internal mammary artery, known as "steal," compromising coronary circulation supplied by the graft. Steal may be asymptomatic or may result in symptoms of myocardial ischemia...

We report the case of a 48-year-old female whom we examined for legal culpability. The proband was taking the dopamine agonist pramipexole as a treatment for Parkinson's disease. In temporal association, she had committed numerous shoplifting offences.While pathological gambling, excessive shopping and hypersexuality have often been described as adverse effects of dopamine agonists, there are only few reports about impulsive stealing in this context.We discuss the synergy of the pharmacological effects with familial, biographic and social factors, suggesting a bio-psycho-social etiology...

BACKGROUND: Behavioural and psychological symptoms of dementia (BPSD) are very common among older people, and previous studies showed that BPSD affects eating behaviour negatively, possibly resulting in undernutrition. In a previous study, we constructed a set of 11 items based on direct observations of older people with dementia during mealtime and named them 'SSADE: signs and symptoms accompanying dementia while eating'. AIMS: This study aimed to conduct a factor analysis to clarify the structure of the set of 11 SSADE items and to analyse the relationship of the SSADE with nutritional status...

To determine the risk of stroke in patients with subclavian steal syndrome (SSS). We identified 165 patients with imaging-provenSSS from two hospitals. Demographic, clinical and imaging data were retrospectively collected. Patients were followed up for stroke events. Stroke occurred in 43 patients with a median follow-up of 28months. Seven of these cases were identified prospectively and 36 cases retrospectively. On multivariate analysis, presence of symptoms at presentation (p=0.029) was a significant predictor of stroke...

As academic institutions across the country raise the scholarly bar for retention, promotion, and tenure, academic leaders are being asked to scholar-ready nursing faculty. With the retirement of senior scholars and too few scholar-mentors to go around, leaders often find themselves squeezed between scholarly expectations on the rise and faculty groups less than ready to meet those expectations. Today's nursing faculty present a formidable scholarly development challenge. A diverse mix of master's-prepared clinicians and recent graduates from doctor of philosophy and doctor of nursing practice programs, they come with a broad range of scholarly learning needs...

INTRODUCTION: The patency of long-term hemodialysis access in end-stage renal disease (ESRD) patients remains a significant challenge. Often these patients are affected with limited venous outflow options, requiring limb abandonment and creation of new access in the contralateral arm. Vascular surgeons are familiar with the exposure of the proximal axillary artery via an infraclavicular incision. The axillary vein is easily exposed through this technique. The use of the hybrid Gore graft can make the venous anastomosis easier...

In this study, Ni-Ti alloy and stainless steal were exposed to artificial saliva containing fibrinogen, IgG or mucin, and the resultant corrosion behavior was studied. The purpose was to determine the mechanisms by which different types of protein contribute to corrosion. The effect of different proteins on the electrochemical resistance of Ni-Ti and SS was tested by potentiodynamic polarization, and the repair capacity of passivation film was tested by cyclic polarization measurements. The dissolved corrosion products were determined by ICP-OES, and the surface was analyzed by SEM and AFM...

In this paper, we present a numerical study of the pulsatile transitional flow crossing a severe real stenosis located right in front of the bifurcation between the right subclavian and right common carotid arteries. The simulation allows one to determine relevant features of this subject-specific flow, such as the pressure waves in the right subclavian and right common carotid arteries. We explain the subclavian steal syndrome suffered by the patient in terms of the drastic pressure drop in the right subclavian artery...

Currently, there is still no consensus about whether animals can ascribe mental states (Theory of Mind) to themselves and others. Showing animals can respond to cues that indicate whether another has visual access to a target or not, and that they are able to use this information as a basis for whom to rely on as an informant, is an important step forward in this direction. Domestic dogs (Canis familiaris) with human informants are an ideal model, because they show high sensitivity towards human eye contact, they have proven able to assess the attentional state of humans in food-stealing or food-begging contexts, and they follow human gaze behind a barrier when searching for food...

The amount and evolutionary impact of horizontal gene transfer in eukaryotes remain contentious issues. A new phylogenomic study suggests that gene transfer from prokaryotes has contributed significantly to the adaptation and metabolic evolution of Blastocystis, the most widespread human gut eukaryotic parasite.
