How Parents Perceive the Potential Risk of a Child-Dog Interaction.

Dog attacks on children are a widespread problem, which can occur when parents fail to realise a potentially dangerous interaction between a dog and a child. The aim of the study was to evaluate the ability of parents to identify dangerous situations from several everyday child-dog interactions and to determine whether the participants connected these situations to a particular breed of dog. Five sets of photographs depicting potentially dangerous interactions from everyday situations between children and three dogs (one of each breed) were presented via an online survey to parents of children no more than 6 years old.

Gas-sensing behaviour of ZnO/diamond nanostructures.

Microstructured single- and double-layered sensor devices based on p-type hydrogen-terminated nanocrystalline diamond (NCD) films and/or n-type ZnO nanorods (NRs) have been obtained via a facile microwave-plasma-enhanced chemical vapour deposition process or a hydrothermal growth procedure. The morphology and crystal structure of the synthesized materials was analysed with scanning electron microscopy, X-ray diffraction measurements and Raman spectroscopy. The gas sensing properties of the sensors based on i) NCD films, ii) ZnO nanorods, and iii) hybrid ZnO NRs/NCD structures were evaluated with respect to oxidizing (i.

Towards the design of an optimal strategy for the production of ergosterol from Saccharomyces cerevisiae yeasts.

The total yield of ergosterol produced by the fermentation of the yeast Saccharomyces cerevisiae depends on the final amount of yeast biomass and the ergosterol content in the cells. At the same time ergosterol purity-defined as percentage of ergosterol in the total sterols in the yeast-is equally important for efficient downstream processing. This study investigated the development of both the ergosterol content and ergosterol purity in different physiological (metabolic) states of the microorganism S.

Portal vein embolisation with application of haematopoietic stem cells in patients with primarily or non-resectable colorectal liver metastases.

Background: Insufficient future liver remnant volume (FLRV) is the main cause of low resectability of liver metastases from colorectal cancer (CLMs). One option for enhancing FLVR growth is the use of portal vein embolisation (PVE) with the application of autologous haematopoietic stem cells (HSCs).

Patients And Methods: PVE with the application of HSCs was used in 11 patients (group 1) with primarily non-resectable CLMs due to insufficient FLRV without signs of extrahepatic metastases.

[Simultaneous procedure in patients with abdominal aortic aneurysm and renal carcinoma].

Introduction: Renal carcinoma (RC) is present in 0.1-3% of patients with abdominal aortic aneurysm (AAA). There are several options for surgical solution as regards the type and timing of the procedure.
