Nonlinear phenomena make animal calls alarming for human listeners

Animal vocalizations are extremely diverse, and evolutionary approaches to understanding this diversity assume some mapping between their acoustic form and communicative function, with specific features serving universal roles. Here, we investigate whether irregular vocal production with nonlinear phenomena contrib-utes to the alarming quality of vertebrate calls. We resynthesized 98 calls of bird

Prosthetic pulmonary valve infectious endocarditis in pediatric congenital heart disease patients

OBJECTIVES: Pulmonary valve implantation (PVI) is common in children with congenital heart disease particularly as they get older. While surgical PVI (SPVI) was the mainstay of treatment for years, percutaneous PVI (PPVI) has evolved into a popular treatment option. The aim of our study was to evaluate the rate of prosthetic pulmonary valve infectious endocarditis (PPVIE) between these two modes o

Absolute Quantification of Donor-Derived Cell-Free DNA Following Pediatric and Adult Heart Transplantation

OBJECTIVE: Traditional rejection surveillance after heart transplantation (HTx) is based on endomyocardial biopsies (EMB), which are invasive, expensive and associated with complications. Monitoring using cell-free DNA (cfDNA) is promising, but most studies report only on the donor fraction (DF) as the percentage of donor derived-cfDNA (dd-cfDNA) relative to total-cfDNA. We evaluated the performan

Sugar intake and cardiovascular disease risk: With an emphasis on genetic and metabolomic biomarkers of sugar intake

Introduction: Contrary to popular belief, there is limited research on sugar intake as a risk factor for cardiovascular disease. While the links between sugar-sweetened beverage intake and cardiovascular disease risk are well-established, little is known about the associations for overall added or free sugar intake and other dietary sources of added sugar. Objective markers of habitual sugar intak

Characterization of spark ignition energy transfer at different phases using pressure-rise calorimetry

The paper presents novel studies on the electrical-to-thermal energy deposition to gas at different phases of a spark. The experiments utilized a 10.9 milliliter custom-built spark calorimeter. The energy transfer efficiencies across spark phases—breakdown+arc, and glow are quantified, emphasizing their importance in ensuring robust ignition. An AC capacitive ignition system was considered in the

Folkparken i Lund : En bortglömd arbetarhistoria

The People’s Park in Lund was one of Sweden’s first public places owned by the labour movement. Today the park has become a municipal re creational facility and cultural centre, and the pivotal role of labour in its creation has all but completely faded. Yet despite this amnesia, urban development plans for the park have been overturned many times with references to the place’s past, which has mad

Oat beta-glucans consumed at breakfast improve glucose tolerance acutely and after a subsequent lunch - a randomized dose-response study in healthy young adults

Oat beta-glucans (OBGs) lower postprandial blood glucose by increasing gastrointestinal viscosity, delaying gastric emptying, and slowing glucose absorption. While the European Food Safety Authority (EFSA) recommends a minimum intake of 4 g of OBGs per 30 g of available carbohydrates (avCHO) for a significant reduction in glycaemic response, this poses formulation challenges. This study investigat

Lactoferrin-derived peptide PXL01 impacts nerve regeneration after sciatic nerve reconstruction in healthy and diabetic rats

INTRODUCTION: Although advanced surgical techniques are available, satisfactory functional outcomes after peripheral nerve injuries are uncommon. Hence, immune-modulating factors such as PXL01, a lactoferrin-derived peptide that improves axonal outgrowth in injured human digital nerves, have gained attention. We previously reported a short-term immunosuppressive effect of PXL01 after the repair of

Evaluation of hematological markers in minor head trauma in the emergency room

Introduction: A rule exists regarding the use of computed tomography (CT) for patients presenting to the emergency department with head trauma and a Glasgow coma score (GCS) of 15; however, it can be difficult to make this decision due to overcrowded emergency rooms or exaggerated patients complaints. We evaluated patients who presented to the emergency room with minor head trauma, and we aimed to

Neurosurgical approaches to spinal infections

Spinal infection is rare. Clinical suspicion is important in patients with nonmechanical neck and/or back pain to make the proper diagnosis in early disease. Before planning surgery, a thorough evaluation of the spinal stability, alignment, and deformity is necessary. Timing of surgery, side of approach, appropriate surgical technique, and spinal instruments used are crucial. Biomechanical preserv

Management of cerebrospinal fluid leak during endoscopic pituitary surgery

Objective: Dural opening and closures are major steps in endoscopic pituitary surgery. Restoring the normal anatomy at the end of the procedure creates a natural barrier between the intrasellar compartment and the sinonasal cavity. Methods: In this study, we present a relatively simple dural opening and closure technique for endoscopic pituitary surgery. This technique provides a better alternativ

Cost and efficacy of perioperative antibiotic prophylaxis in a State Hospital in turkey

Objective: The objective of this study was to evaluate the applications and procedures of perioperative antibiotic prophylaxis (PAP) in terms of their cost and efficacy in a state hospital in Turkey. Setting: A 372-bed, state hospital in Isparta, Turkey. Method:The investigation was performed between May and August 2011 in six surgical wards. All of the surgical procedures were followed up and ant

Subdural empyema and unilateral pansinusitis due to a tooth infection

Paranasal sinus infections are very common. Dental infections, tumours and anatomical malformations can cause unilateral sinusitis. Most cases can be treated without complications. However, rare life-threatening intracranial complications can occur. Generally, an intracranial complication progresses rapidly and can cause meningismus, focal neurological disorders, loss of consciousness and seizures

The relationship basal ganglia calcification and level of 25(OH)-D and parathyroid hormone in patients with Parkinson's disease

Objective: This study aims to investigate the relationship between the levels of 25- Hydroxyvitamin D (25(OH)-D), parathyroid hormone (PTH) and basal ganglia calcification (BGC) in patients with Parkinson's disease (PD). Method: The study population consisted of 32 patients with PD who were admitted to the Neurology Clinic of Antakya State Hospital in 2010 as well as 32 healthy control subjects. S
