Impact of effective micro-organisms (EM) on the yield, growth and bio-chemical properties of lettuce when applied to soil and leaves.

Background: In today's conditions, it is not possible to eliminate chemical inputs without reducing food production. Therefore, integrated methods that reduce the negative effects of chemical inputs are needed. One of the alternatives is the use of beneficial bacteria, which can both improve the yield and quality of vegetable crops and reduce the use of chemical fertilisers.

Development of a Novel Adapter to Enable Less-Invasive Left Ventricular Assist Device Implantation via the Left Ventricular Apex.

The first prototype of an adapter to enable left ventricular assist device (LVAD) implantation solely via the left ventricular (LV) apex and without requiring cardiopulmonary bypass (CPB) was tested in healthy and acutely failing pig hearts. The adapter consists of a fixation, blood guiding, and connecting module fitting to a HeartMate 3 (HM3; Abbott, Chicago, IL) pump. Implantation was performed via a left thoracotomy in five pigs (96 ± 18 kg).

Clinical and laboratory predictors of survival for pediatric patients on non-postcardiotomy extracorporeal membrane oxygenation (ECMO).

Extracorporeal membrane oxygenation (ECMO) is used in pediatric patients with severe cardiopulmonary failure who do not respond to conventional therapy; only a few studies have been conducted in Turkey. We present the experience of pediatric ECMO with the aim of showing factors affecting mortality. We retrospectively reviewed our ECMO database to identify patients who received ECMO from October 2015 to March 2018.

Outcomes of arterial switch operation for Taussig-Bing anomaly versus transposition of great arteries and ventricular septal defect.

Background: This study aims to present the outcomes of arterial switch operation for Taussig-Bing anomaly versus transposition of the great arteries and ventricular septal defect.

Methods: Between November 2010 and December 2016, a total of 100 consecutive arterial switch operations in 42 pediatric patients (25 males, 17 females; median age 17 days; range, 2 to 210 days) were performed in two centers. Among them, 42 patients had associated ventricular septal defect and were diagnosed with Taussig-Bing anomaly (n=15) or transposition of the great arteries and ventricular septal defect (n=27).

Transcatheter mitral valve chord repair.

The field of mitral valve disease diagnosis and management is rapidly evolving. New understanding of pathophysiology and improvements in the adoption of sophisticated multimodality imaging modalities have led to early diagnosis and to more complex treatment. The most common cause of mitral regurgitation (MR) in the western world is in the primary alteration of the valve, which leads to degenerative leaflet prolapse due to chordal elongation or rupture and annular dilatation.

Extracorporeal membrane oxygenation for the support of pediatric patients with acute fulminant myocarditis.

Şık G, Annayev A, Demirbuğa A, Deliceo E, Aydın S, Erek E, Demir Hİ, Çıtak A. Extracorporeal membrane oxygenation for the support of pediatric patients with acute fulminant myocarditis. Turk J Pediatr 2019; 61: 867-872.

Long-term follow-up results of lung perfusion studies after transcatheter closure of patent ductus arteriosus.

Objective: This study presents the long-term follow-up of patients who developed left lung perfusion (LLP) abnormalities following patent ductus arteriosus (PDA) closure with various device types.

Design: The study includes 23 adult and pediatric patients who had undergone transcatheter PDA closure and were shown to have decreased LLP (<40%) by the first scintigraphy performed within the average follow-up period of 14.0 ± 8.

Transthoracic echocardiographic guidance during transcatheter closure of atrial septal defects in children and adults.

The purpose of this study was to evaluate the safety and efficacy of transcatheter atrial septal defect (ASD) closure guided by transthoracic echocardiography (TTE). Since 2004, ASD closure was performed successfully in total 337 patients. Transthoracic echocardiography guidance was used in 206 patients (61.

A comparative study of Cardi-O-Fix septal occluder versus Amplatzer septal occluder in percutaneous closure of secundum atrial septal defects.

Aim: We sought to investigate the safety and efficacy of Cardio-O-Fix septal occluder (CSO) in percutaneous closure of atrial septal defects (ASD) as compared to the Amplatzer septal occluder (ASO).

Methods: A consecutive of 351 patients received transcatheter ASD closure with CSO or ASO from July 2004 to October 2010 were studied. The ASDs were divided into simple- (isolated defects <26 mm) or complex-types (isolated defect ≥26 mm, double or multifenestrated defects).

[Our medium-term results with aortic balloon valvuloplasty and factors affecting development of aortic regurgitation].

Objective: The objective of this study was to assess medium-term results of aortic balloon valvuloplasty (ABV) in congenital aortic stenosis and to determine factors affecting development of aortic regurgitation (AR).

Methods: Between September 2003 and January 2010, 114 ABV procedures performed on 97 patients analyzed retrospectively. Patients were evaluated in terms of transvalvular gradients before and after procedure, development of new aortic insufficiency or increase in the current insufficiency and factors affecting the procedural success and development of aortic insufficiency.

Multiple transcatheter interventions in the same session in congenital cardiopathies.

Background: To investigate the methods of percutaneous transcatheter interventions for combined congenital heart disease and to evaluate its efficacy in children.

Materials And Methods: Thirty cases (ages 3 days-13.5 years, body weight 3-35 kg) that underwent two multiple transcatheter interventions for combined or solitary congenital heart disease were retrospectively analyzed and presented.

Anomalous origin of one pulmonary artery branch from the ascending aorta: experience of our center.

Objectives: Anomalous origin of one pulmonary artery branch from the aorta in the presence of separate aortic and pulmonary valves is a rare but important entity necessitating early diagnosis and surgery to prevent irreversible vascular pulmonary disease. We evaluated our experience with seven infants having this anomaly.

Study Design: Between December 2003 and 2009, a total of seven infants (2 girls, 5 boys, age range 4 days to 84 days) were diagnosed as having anomalous origin of one pulmonary artery branch from the aorta.

Control of the mushroom phorid fly, Megaselia halterata (Wood), with plant extracts.

Background: The most serious insect pest problems affecting the cultivation of mushroom [Agaricus bisporus (Lange) Imbach] in Turkey are mushroom flies (sciarids, cecids and phorids). Mushroom phorid fly, Megaselia halterata (Wood), is the most common insect pest species during April-October. The aim of this study was to evaluate the potential for eight botanical materials (two commercial neem-based products and six hot-water plant extracts) to control M.
