The original monograph on valvular prostheses in Surgical Technology International was published in 1993. It represents a milestone and a reference point for critically organizing information on a complex and rapidly evolving topic. The last update was published in 2010. Since then, there have been significant developments regarding both "traditional" surgical prosthesis and valves for transcatheter implantation. Both bioprostheses and mechanical prostheses continue to evolve with respect to both their design and materials to further optimize hemodynamics and prevent a patient-prosthesis mismatch...

There is evidence to support that ROSs are increased in Parkinson's disease (PD). Our recent research showed that angiotensin II (Ang II) participated in the pathogenesis of PD by triggering oxidative stress. Angiotensin-(1-7)[Ang-(1-7)] has been shown to moderate the adverse effects of the Ang II in many diseases. The purpose of the present study was to determine whether the Ang-(1-7) could have similar effects in CATH.a neurons. We used rotenone-induced neuron injury models to evaluate changes in cultured CATH...

Introduction: Determination of the QT interval dispersion by means of a standard ECG at rest has been widely used for cardiovascular risk assessment during the last 15 years as one of the recent explanations for the development of life threatening ventricular arrhythmias. However, little is known about the relation between QT dispersion and the severity of coronary artery atherosclerosis as defined by SYNTAX score. Aim of work: The present study was done to assess the correlation between QTc dispersion and the severity of coronary artery disease in acute ST elevation myocardial infarction (STEMI) detected by SYNTAX score...

Epidemiologic studies have demonstrated that women account for two-thirds of Alzheimer's disease (AD) cases, for which the decline in circulating gonadal hormone is considered to be one of the major risk factors. In addition, ovarian hormone deficiency may affect β-amyloid (Aβ) deposition, which has a close relationship with autophagic flux. In this study, we investigated the impact of short-term or long-term ovarian hormone deprivation on two mouse models, the non-transgenic (wild-type) and the APP/PS1 double-transgenic AD (2×TgAD) model...

The presence of high-risk features on candidates to percutaneous revascularization is increasingly leading to Impella®-assisted procedures (IAPs). While IAPs are safe and effective procedures, they still require managing a degree of complexity. Clinicians often rely on their ability to recall every step of operative procedures. However, during stressful situations, levels of cognitive function are compromised leading to planning and execution failures and decreased safety. Many high-risk activities such as aviation, aerospace industry, and nuclear plants have been using protocols, standardized procedures and checklists for many years...

Understanding the resilience of early societies to climate change is an essential part of exploring the environmental sensitivity of human populations. There is significant interest in the role of abrupt climate events as a driver of early Holocene human activity, but there are very few well-dated records directly compared with local climate archives. Here, we present evidence from the internationally important Mesolithic site of Star Carr showing occupation during the early Holocene, which is directly compared with a high-resolution palaeoclimate record from neighbouring lake beds...

EDITORIAL
Tariq Ali Ahmad, IanC Gilchrist
Cataract formation in the posterior subcapsular region of the lens is a lesion highly specific to both high-dose acute radiation exposure and chronic low-dose exposure. Low-dose radiation may not manifest lens changes for several decades after initial exposure. Cardiac catheterization team members need to be educated on, and protected from, this form of radiation injury as its long latency period between exposure and physical damage may acutely reduce the sense of hazard amongst healthcare radiation workers...

Real time radiation dose monitoring in the cath lab may provide immediate feedback for potential dose reduction during PCI. Radiation dose monitoring to predict potential tissue injury utilizes equipment measured air Kerma at the interventional reference point (IRP) with then calculated specific tissue peak skin dose. The role of the cath lab Quality Committee is not only to assess individual high dose radiation cases but also to create processes and assess new technologies to assure radiation dose is best utilized in all cases...

BACKGROUND: Few data exist on temporal evolution of antithrombotic agent use in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) in Italy. We sought to compare data from the most recent prospective, multicenter, nationwide registries conducted in Italy, namely EYESHOT and SCOPE. METHODS: EYESHOT enrolled 2585 consecutive ACS patients, both ST-segment elevation myocardial infarction (STEMI) and non-ST elevation ACS (NSTE-ACS), admitted to 203 Italian coronary care units over a 3-week period (2-22 Dec 2013 and 27 Jan-16 Feb 2014)...

Coproduction of research between consumers of mental health services and nonconsumer mental health researchers is increasing. There is some research available describing consumer perspectives of this experience. However, there is a notable lack of research on other (nonconsumer) researcher experiences of and views about consumer involvement in coproduced research. A qualitative exploratory study was undertaken to examine perspectives of mental health researchers about consumer involvement in research. In-depth individual interviews were undertaken with 11 nonconsumer mental health researchers in Australia and New Zealand...

Joseph M DeCunha, Shirin A Enger
PURPOSE: Renewed interest is being expressed in intravascular brachytherapy (IVBT). A number of unresolved issues exist in the discipline. Providing a homogeneous and adequate dose to the target remains difficult in IVBT. The guidewire that delivers the device to the target, arterial plaques, and stent struts are all known to reduce the dose delivered to target. The viability and efficacy of a proposed IVBT delivery system designed to resolve the issue of guidewire attenuation is evaluated and compared to that of a popular and commercially available IVBT device...

Several types of intravascular devices and catheters are frequently used for long-term drug therapy, especially for oncological patients. As a result, complications are becoming increasingly common, namely catheter embolization. Retrieving these devices is important, as embolized fragments may lead to serious consequences, such as arrhythmias, myocardial injury, thrombosis, infection, and even perforation and death. We describe 2 cases of long-term drug catheter (Port-A-Cath) fracture, incidentally documented in a routine chest radiograph...

Cationic antimicrobial peptides (AMPs) are considered as important candidate therapeutic agents, which exert potent microbicidal properties against bacteria, fungi and some viruses. Based on our previous findings king cobra cathelicidin (OH-CATH) is a 34-amino acid peptide that exerts strong antibacterial and weak hemolytic activity. The aim of this research is to evaluate the efficacy of both OH-CATH30 and its analog D-OH-CATH30 against clinical isolates comparing with routinely utilized antibiotics in vitro...

Contrast echocardiography with agitated saline is used to assess mainly the existence of interatrial communication. We report a case of a 26-year-old woman, with a "port-a-cath" central venous line, who had an unusual finding in agitated saline contrast echocardiography. Multimodality imaging revealed occlusion of superior vena cava and a systemic-to-pulmonary venous shunt.

In phylogenomic profiling, the genomic context based methods are based on the observation that two or more proteins having the same pattern of presence or absence in many diverse genomes most likely have a functional link. In this research work, a tool (PATSIM) has been developed to predict the protein patterns based on the SOPM tool. In this tool, the secondary structure for CATH database protein sequences, predicted by the SOPM (Self Optimized Prediction Method) server is passed as input to fulfill objectives such as, (i) Predict the Amino Acid Pattern using the proposed Hybrid KMP and BM algorithm, (ii) Predict the physiochemical properties such as Hydrophobic Non-Polar ALKYL Amino Acid groups, Hydrophobic Non-Polar AROMATIC Amino Acid groups, Hydrophilic Polar Neutral Amino Acid groups, Hydrophilic Polar Acidic Amino Acid groups and Hydrophilic Polar Basic Amino Acid groups of protein sequence, (iii) Predict the secondary structure of protein where the structure of protein sequence is unknown, and (iv) Similarity analysis of protein sequence (structure unknown) with the CATH database...
