Disorders of haemostasis and haemocoagulation are often seen in patients with cancer as a part of paraneoplastic syndrome. Thrombotic and/or haemorrhagic complications are the second most common cause of mortality in patients with cancer. The evaluation of the haemostatic parameters of 67 patients with gastric cancer h…

INTRODUCTION: Cases of venous thrombosis associated with celiac disease have been rarely published. We report a case of celiac disease associated with deep venous thrombosis in the left leg. MATERIAL AND METHODS: A 44-year-old man was admitted to the hospital due to diarrhea, which was present for three months. The di…

BACKGROUND: The exact definition of natural history is important in ulcerative colitis for both clinicians and patients, because it may play a role in the development of treatment strategies for physicians and in the future prospect for patients. In this study, we review the clinical evolution of patients with ulcerati…

In the present case, ultrasound examination ruled out the presence of hematosalpinx or other gynecological tumors. This was of great importance to the surgical intervention, especially for avoiding laparotomy. Dilatation of the vagina and uterus, due to imperforate hymen with retrograde menstruation should be considere…

BACKGROUND: Early and excessive alcohol use is a significant threat to healthy development. Evidence supports the effectiveness of electronic alcohol interventions for young drinkers. However, effects are typically small and studies targeting under 18-year-olds are scarce. This trial is the first to evaluate the effect…

To investigate the role of potent MAO-B inhibitor deprenyl in fertilized females, we have evaluated the effect of chronic treatment with deprenyl at a low dosage on preimplantation embryo development in Wistar rats. We have found that the number of isolated embryos per rat did not differ between experimental and contro…

This article presents a novel wideband (WB) tilted-beam end-fire planar antenna for microwave and millimeter-wave (mmWave) applications. The antenna comprises of a microstrip fed double semi-circular rings over a curvilinear slotted ground plane. It is impedance matched over a broad frequency range from 11.5 to 62.5&#x…

The intention of authors of this article was not to interprete or even to criticise the official documents of the Europen Commission. We just want to put a flash onto unsolved problems in higher education which seem to hamper the ongoing process of harmonisation of higher education internal structure within the Europea…

We study the phase behaviour of hard spheres confined between two parallel hard plates using extensive computer simulations. We determine the full equilibrium phase diagram for arbitrary densities and plate separations from one to five hard-sphere diameters using free energy calculations. We find a first-order fluid-so…

BACKGROUND: Anthroposophic hospitals provide integrative medical care by complementing conventional (CON) with anthroposophic medicine (AM). They teach integrative medicine in postgraduate medical training (PGMT). In a first evaluation of PGMT quality in AM, we analyzed the problems of this training from the perspectiv…

In this article we will try to find out if the prefixes anti-, contra-, counter-, de-, dys-, ex-, extra-, mal- can negate the words they combine with (Ref. 9). Full Text (Free, PDF) www.bmj.sk.

BACKGROUND: The paper examines Co(II)-amino acid-imidazole systems (where amino acid = L-α-amino acid: alanine, asparagine, histidine) which, when in aqueous solutions, activate and reversibly take up dioxygen, while maintaining the structural scheme of the heme group (imidazole as axial ligand and Oupt…

An improvement of examination methods in ophthalmology, technical digitalisation and knowledge of validity of examinations in various diseases contributes to early diagnostics, thereby leading to an opportunity for early treatment of eye disorders. Standard introduction of the so-called optical coherence tomography int…

Human interest in negation dates back to thousands of years ago and concerns not only Linguistics, Logic, Psychology, and Mathematics. A lot of everyday words have negative meaning expressed by means of negative prefixes. Such type of negation is called word, or affixal negation. Affixal negation is a process of word-f…

Accurate fault diagnosis of analog circuits is critical for ensuring the reliability of modern electronic systems. Two practical challenges hinder data-driven methods: data imbalance, where certain fault modes are rare, and variable operating conditions, where models trained under one fault severity fail to generalize…

In this study, authors present a case report of a 10 months old patient with burn injuries involving 20.5 % body surface area, grades 2a and 2b. According to the continuous monitoring of hemodynamic parameters by PiCCO (Pulsion Medical Systems, Munich, Germany), fluid therapy was successfully managed. Despite of an inc…

We present a case in which the diagnosis of the ovarian carcinoma was made only by the free peritoneal fluid cytology as all the other specimens were negative for malignancy. We discuss the role of laboratory testing of the free peritoneal fluid even in small amounts or of the peritoneal drainage in cases of ovarian cy…

Accurate characterization of aerodynamic stability coefficients is essential for predicting the dynamic behavior of atmospheric re-entry vehicles. Estimating these coefficients from free-flight data is challenging due to nonlinear flow–structure coupling, limited data, and high computational costs. Existing nonl…

Early diagnosis of expansive formations enables efficient therapy and maximal reduction of remaining neurological damage. Schwannoma situated entirely within the inner auditory canal with free pontocerebellar angle is a rather rare event. Of significant diagnostical help are auditory evoked potentials (AEP), computeris…

OBJECTIVE: We describe a working software technology that enables educators to incorporate their expertise and teaching style into highly interactive and Socratic educational material for distribution on the world wide web. MATERIALS/METHODS: A graphically oriented interactive authoring system was developed to enable…
