Article
Earlier studies suggested that specific Echinacea preparations might decrease anxiety. To further study the issue, we performed a double blind, placebo controlled trial with a standardized Echinacea angustifolia root extract. Participants were volunteers scoring above 45 points on the state or on the trait subscale of the State Trait Anxiety Invent...
Article
We have revealed intra-population variability among venom samples from several individual European adders (Vipera berus berus) within a defined population in Eastern Hungary. Individual differences in venom pattern were noticed, both gender-specific and age-related, by one-dimensional electrophoresis. Gelatin zymography demonstrated that these indi...

The ATP-Binding Cassette (ABC)-transporter MultiDrug Resistance Protein 1 (MDR1) and Multidrug Resistance Related Protein 1 (MRP1) are expressed on the surface of enterocytes, which has led to the belief that these high capacity transporters are responsible for modulating chemosensitvity of colorectal cancer. Several immunohistochemistry and revers...

HER2-positive breast cancers usually benefit from anti-HER2 therapy, thus, HER2 evaluation became inevitable for patient selection. HER2-negative (IHC 0, 1+) and strong positive (IHC 3+) cases can easily be interpreted with immunohistochemistry, but equivocal (IHC 2+) cases require further analysis of HER2 gene amplification using in situ hybridiza...

Introduction: Fluorescence in situ hybridisation is a widely used diagnostic process in the pathology. This method can reveal the genetic background of malignant lesions. The aim of this study was to develop and optimize an image segmentation algorithm specifically for FISH quantification. Moreover we would like validate the results of our quantifi...

First paragraph (this article has no abstract) In the last decade anti-HER2 treatment became one of the best examples for targeted treatment. Since the aggressive behavior of HER2-positive breast cancers could have been successfully reduced by trastuzumab therapy, HER2 positive breast cancers recently show improving prognosis. According to a four-...
Article
We report a recent case of common adder (Vipera berus) envenoming causing paralytic signs and symptoms. A 12-year-old girl was bitten by the nominate subspecies of the common adder (V. berus berus) in eastern Hungary on May 2, 2012, 22 km away from where the first neurotoxic V. berus berus envenoming was reported in 2008. The patient developed unam...
Article
We investigated the toxicity, psychotropic side effects and anxiolytic potential of an Echinacea angustifolia extract that produced promising effects in laboratory tests performed earlier. Rats were studied in the elevated plus-maze, conditioned fear, open-field, object recognition and conditioned place preference tests. Toxicity was studied in rat...

We investigated the toxicity, psychotropic side effects and anxiolytic potential of an Echinacea angustifolia extract that produced promising effects in laboratory tests performed earlier. Rats were studied in the elevated plus‐maze, conditioned fear, open‐field, object recognition and conditioned place preference tests. Toxicity was studied in rat...
Article
Consequences of bites by the Common adder (Vipera berus) were reviewed in this study. Patients bitten by snakes from different populations may develop variable symptoms due to geographical venom variation. The correct diagnosis of snake bites and the knowledge of the distribution of venomous snake taxa have a crucial impact on snake bite therapy. T...

The first overall clinical description of envenomings by the lowland populations of the Balkan adder (Vipera berus bosniensis) is provided by this study. Fifty-four incidents have been collected retrospectively from the south-western Hungarian and the northern Croatian distribution area of the taxon. There were five (9%) asymptomatic, 24 (44%) mild...

The immunohistochemical detection of estrogen (ER) and progesterone (PR) receptors in breast cancer is routinely used for prognostic and predictive testing. Whole slide digitalization supported by dedicated software tools allows quantization of the image objects (e.g. cell membrane, nuclei) and an unbiased analysis of immunostaining results. Valida...
Article
We report a misdiagnosed Vipera envenoming from northern Hungary from an as yet unknown viper-locality. A 64-year-old previously healthy male was bitten in the Bükk Mountains in July 2009, and has not presented at a doctor on the day of accident, although he suffered from mild and transient systemic symptoms and moderate local consequences followin...
Article

The vipers in the Vipera (Acridophaga) ursinii complex are small-sized insectivorous snakes found in parts of central and southern Europe. Subspecies include Vipera ursinii ursinii, Vipera ursinii moldavica, Vipera ursinii macrops, Vipera ursinii rakosiensis, and Vipera ursinii graeca and are commonly known as the meadow vipers. These are the least...

We give a comprehensive overview of the observation of the golden jackal or reed wolf (Canis aureus), from the beginning of the 1800s until 1995 in Hungary, based on the available literature. We discuss 57 observations from the period surveyed, seven reports that mentioned canids but certainly not a jackal, 26 questionable cases, and 16 records tha...

The distribution of the Vipera ursinii complex in Romania is presented, based on records from the scientific literature since the 1800s and results of our own surveys carried out between 1997 and 2007. Altogether, 22 historical and current localities of the Vipera (Acridophaga) group are now known in Romania. Additionally, two erroneous records wer...

Carl Linnaeus (1707–1778) described three taxa that are currently in the synonymy of Vipera berus: Coluber Berus, Coluber Chersea and Coluber Prester. We survey the existing preserved specimens of Vipera berus in the collections at Uppsala University Museum of Evolution and the Swedish Museum of Natural History, Stockholm. We give a short account o...

Epidemiological and clinical aspects of snakebites in Hungary between 1970 and 2006 were surveyed. A total of 97 cases were recorded from 21 species, including the two native vipers, Vipera berus and Vipera ursinii, and various exotic species represented by Viperidae, Elapidae, and Colubridae. Bites by native species on laymen are uncommon (17 case...

A case of Rhinoceros viper (Bitis nasicornis) bite is reported. The bitten hand distended to the wrist, which was tense and painful, with only mild local livid discolouration manifested around the fang mark. Slight hypertension with moderate tachycardia and temporary coagulopathy were observed. The patient received analgesic and intravenous fluids,...

The records of albino, partial albino, and leucistic individuals among four species of European Viperinae (Vipera ammodytes, Vipera aspis, Vipera seoanei, and Vipera berus) were summarized based on literature records, mu-seum material, reports of field herpetologists and herpetoculturists, and a short description of all reported speci-mens was made...

Summary The faunistic researches are very important, because they are the bases of the ecological studies. This paper presents data resulted from an analysis of Barn Owl (Tyto alba) pellets. The analyzed pellets were collected in summer of 1999 from 13 different sampling points within the territory of Satu Mare county. We identified 3096 exemplars...
