IAA and ACC deaminase producing-bacteria isolated from the rhizosphere of pineapple plants grown under different abiotic and biotic stresses.

The roles of plant growth-promoting rhizobacteria in promoting plant growth and soil health, including alteration in plant metabolism and production of phytohormones such as indole-3-acetic acid (IAA) and the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, are indisputable. This study aimed to isolate and characterize beneficial bacteria isolated from the rhizosphere of pineapple from distinct stress-inducing habitats, including water excess-, herbicide-over-treated-, and pathogen-infected areas at PT Great Giant Foods located in Lampung, Indonesia. The isolated bacteria were screened based on IAA production and ACC deaminase activities.

Left ventricular function and clinical outcome in transient left ventricular ballooning syndrome.

Background: It is unknown if the severity of left ventricular dysfunction in patients with transient left ventricular ballooning syndrome (TLVBS) adversely affects clinical outcome. Furthermore, it remains unclear if the patterns of ventricular involvement are distinct patterns or if they represent varying stages of ventricular involvement.

Methods And Results: All patients with TLVBS who presented to our hospital from August 1998 to August 2012 were prospectively identified and entered into a clinical database.

STACCATO (Assessment of Stent sTrut Apposition and Coverage in Coronary ArTeries with Optical coherence tomography in patients with STEMI, NSTEMI and stable/unstable angina undergoing everolimus vs. biolimus A9-eluting stent implantation): a randomised controlled trial.

Aims: To compare tissue coverage in coronary lesions stented with durable fluoropolymer-coated everolimus-eluting stents (EES) vs. biodegradable polymer-coated biolimus A9-eluting stents (BES).

Methods And Results: Sixty-four patients (64 lesions) with de novo coronary artery lesions were randomised to percutaneous treatment with XIENCE EES (Abbott Vascular, Santa Clara, CA, USA) vs.

Optical coherence tomography study of healing characteristics of paclitaxel-eluting balloons vs. everolimus-eluting stents for in-stent restenosis: the SEDUCE (Safety and Efficacy of a Drug elUting balloon in Coronary artery rEstenosis) randomised clinical trial.

Aims: Little is known about the respective healing responses and clinical efficacy and safety of drug-eluting balloons (DEB) and the second generation of drug-eluting stents (DES) when used to treat in-stent restenosis (ISR). In this study, we set out to compare prospectively the healing characteristics, as assessed by optical coherence tomography (OCT), of DEB versus DES after treatment of ISR in bare metal stents (BMS).

Methods And Results: Fifty patients with BMS ISR were randomised to treatment with a paclitaxel-eluting balloon vs.

Automated detection and quantification of clusters of malapposed and uncovered intracoronary stent struts assessed with optical coherence tomography.

To date, accurate quantification and localization of malapposed and uncovered struts needs manual and time consuming analysis of large datasets. To develop an algorithm for automated detection and quantification of clusters of malapposed and uncovered struts in optical coherence tomography (OCT) pullbacks, including comprehensive information about their three-dimensional spatial distribution. 64 lesions in 64 patients treated with drug-eluting stent underwent assessment with OCT immediately after implantation and at 9-month follow-up (55 patients).

Time course of electrocardiographic changes in transient left ventricular ballooning syndrome.

Background: We sought to describe, for the first time, in detail the time course of electrocardiographic (ECG) changes in transient left ventricular ballooning syndrome (TLVBS) from acute onset until 1 year after presentation.

Methods: The serial ECGs of all patients identified with TLVBS who presented to our cardiology department from August 1998 to August 2012 were analyzed, from admission to 1-year follow-up, with respect to time from onset of symptoms.

Results: In total, 145 TLVBS episodes were identified in 139 patients.

Coronary spasm is not a benign entity.

We present a case of unrecognized recurrent severe coronary spasm treated by percutaneous coronary interventions leading to catastrophic complications ultimately requiring emergency coronary artery bypass grafting and later, following occlusion of the grafts, recanalization of a totally occluded left coronary artery. Throughout the case history the recognition and management of this challenging coronary phenomenon is discussed.

Healing responses after bifurcation stenting with the dedicated TRYTON Side-Branch Stent™ in combination with XIENCE-V™ stents: a clinical, angiography, fractional flow reserve, and optical coherence tomography study: the PYTON (Prospective evaluation of the TRYTON Side-Branch Stent™ with an additional XIENCE-v™ everolimus-eluting stent in coronary bifurcation lesions) study.

Objectives: We evaluated healing responses with optical coherence tomography (OCT), and clinical and angiographic outcome after bifurcation stenting with the TRYTON Side-Branch Stent™.

Background: Dedicated bifurcation stents have been proposed as a potential alternative for treatment of true coronary bifurcation lesions.

Methods: We treated 20 consecutive patients with coronary bifurcation lesions and significant involvement of the side-branch (SB) with the TRYTON Stent and an additional XIENCE-V™ everolimus-eluting stent.

Thrombotic complication during intracoronary imaging.

Intracoronary imaging with intracoronary ultrasound and coherence tomography is often used in the follow-up of coronary stent implantation. The present case shows an infrequent complication of these procedures, suggesting our continued attention to the selective use of these invasive procedures.

Thrombus in a normal left ventricle: a cardiac manifestation of pheochromocytoma.

In this case report, a patient with a thrombus in a normal-sized and functional left ventricular is described. The thrombus was most likely formed during pheochromocytoma crisis with severe transient wall motion abnormalities.

Patent ductus arteriosus in adults: Case report and review illustrating the spectrum of the disease.

Patent ductus arteriosus (PDA) is a congenital heart defect in which the ductus arteriosus, a vascular structure between the pulmonary artery and the aorta that normally closes shortly after birth, remains open. We present two cases of adults with PDA. A 28-year-old lady had a small PDA without any symptoms or left heart overload.
