Potential Teratogenicity Effects of Metals on Avian Embryos.

Agricultural areas can provide sources of food and hiding and nesting places for wild birds. Thus, the chemical load of potentially toxic elements (Cd, Cu, Pb) due to industrial and agricultural activities can affect not only the adult birds but also the embryos developing in the egg. The toxic effects of heavy metals applied alone were investigated on chicken embryos in the early and late stages of embryonic development using injection and immersion treatment methods.

Reproductive toxicological changes in avian embryos due to a pesticide and an environmental contaminant.

Single and simultaneous toxic effects of glyphosate (Amega Up, 360 g L-1, 4%) and copper sulphate (0.01%) were studied in avian embryos treated either with injection directly into the air chamber or by immersion application for 30 min on day 0 of incubation. Alterations of the chicken embryos were evaluated during necropsy performed on day 19 of incubation, together with mortality, body weight and the type of developmental abnormalities.

Comparison of metal burden in different muscle tissues of Great cormorant (Phalacrocorax carbo).

Concentrations of 12 metals (As, Ba, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb and Zn) were examined in the pectoral and thigh muscle of great cormorants (Phalacrocorax carbo). The samples were collected from Central Tisza-Jászság Nature Conservation Area in Hungary. The tissue samples were analysed by inductively coupled plasma optical emission spectroscopy (ICP-OES).

Impact of periprocedural morphine use on mortality in STEMI patients treated with primary PCI.

Background: Intravenous morphine (MO) decreases the effect of all oral platelet P2Y12 receptor inhibitors in vitro and observational reports suggest that its use may be associated with larger infarct size. Yet, there are limited data available about the impact of this interaction on clinical outcomes. We studied the effect of MO on mortality in ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI using a prospective registry.

Guidance means accuracy: A randomized clinical trial on freehand versus guided dental implantation.

Objectives: A randomized clinical trial was conducted to compare all three known static guided surgery protocols (pilot, partial, and full) with each other and with freehand surgery in terms of accuracy, under the same conditions.

Material And Methods: A total of 207 implants of the same brand and type were placed in 101 partially edentulous volunteers in need of implantation in the mandible or maxilla or both. All cases were digitally planned, and the comparison of the planned and actual implant positions was performed using a medical image analysis software with dedicated algorithms.

Impact of Selective Aspiration Thrombectomy on Mortality in Patients With ST-Segment Elevation Myocardial Infarction.

Although routine aspiration thrombectomy (AT) is not recommended by the current American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions guideline, for selected cases, a class IIb indication is given because of lack of data. We studied the impact of selective AT on mortality in patients with ST-segment elevation myocardial infarction using a prospective registry. We analyzed data of 1,255 patients, of whom 535 underwent AT based on operator's decision.

A novel risk model including vascular access site for predicting 30-day mortality after primary PCI: The ALPHA score.

Background: The mortality benefit of transradial primary PCI has been shown by several studies. Previous risk models have not considered access site as a candidate predictor and many of them were developed using low risk populations of randomized trials. We conducted a prospective cohort study to construct and validate an admission risk model including access site as candidate variable for predicting 30-day mortality after primary PCI.

Need for prophylactic application of verapamil in transradial coronary procedures: a randomized trial. The VITRIOL (is Verapamil In TransRadial Interventions OmittabLe?) trial.

Background: Verapamil is traditionally applied prophylactically in transradial procedures to prevent radial artery spasm. However, verapamil may have side effects and is contraindicated in some clinical settings.

Methods And Results: During an investigator-initiated, randomized, double-blind trial, we evaluated the need for preventive verapamil administration.

Protective effects of L-alpha-glycerylphosphorylcholine on ischaemia-reperfusion-induced inflammatory reactions.

Purpose: Choline-containing dietary phospholipids, including phosphatidylcholine (PC), may function as anti-inflammatory substances, but the mechanism remains largely unknown. We investigated the effects of L-alpha-glycerylphosphorylcholine (GPC), a deacylated PC derivative, in a rodent model of small intestinal ischaemia-reperfusion (IR) injury.

Methods: Anaesthetized Sprague-Dawley rats were divided into control, mesenteric IR (45 min mesenteric artery occlusion, followed by 180 min reperfusion), IR with GPC pretreatment (16.

[Evaluation of the accuracy of inferior petrosal sinus sampling in the differential diagnosis of ACTH-dependent Cushing's syndrome].

The differentiation of adrenocorticotropic hormone producing pituitary adenoma (Cushing's disease) from the ectopic ACTH syndrome is always a complex and difficult task, and in rare cases it is not possible to differentiate between the two disorders, even with the use of dynamic endocrine tests and the most advanced imaging techniques. Inferior petrosal sinus sampling (IPSS) with subsequent ACTH measurements became the gold-standard method of the differential diagnostic process. 34 patients with ACTH dependent Cushing's syndrome in whom the source of ACTH secretion couldn't be identified unambiguously with imaging techniques and/or dynamic endocrine tests underwent altogether 41 IPSS between 1999 and 2005.

[Diagnosis and treatment outcome in primary aldosteronism based on a retrospective analysis of 187 cases].

Introduction: Primary aldosteronism is the most common form of mineralocorticoid hypertension. The disease has been described by Jerome W. Conn in 1955; since that time there has been a great progress in the knowledge concerning the prevalence, diagnostics and treatment of the disease.

[Percutaneous coronary intervention without on-site cardiac surgery: the first one thousand patients].

At the two hospitals, first percutaneous coronary intervention was performed on 1031 patients (700 male and 331 female, average age 59.8 +/- 15.1 years) between July 2000 and June 2002.

[Surgery of the thymus].

On the occasion of the 50th anniversary of Gyula Sebestény's death, an overview was prepared on the surgery of the thymic gland that was closely connected to his thoracic surgical activity. His results with thymectomy in myasthenia gravis were published as the second study on this topic in Europe and the first in Hungary. The early thymic surgery was based on pathological observations.
