The effect of surgical repair of the chest on postural stability among patients with pectus excavatum.

Pectus excavatum is the most encountered of chest wall deformities. It may produce respiratory and cardiovascular symptoms, hence surgical repair of this defect is performed. The procedure involving the insertion of metal bars under the sternum (the Nuss procedure) usually brings significant improvement to patients.

Optimized DNA-based identification of Toxocara spp. eggs in soil and sand samples.

Background: Toxocara canis and Toxocara cati are globally distributed roundworms and causative agents of human toxocariasis, via ingestion of Toxocara eggs. Control of Toxocara infections is constrained by a lack of sensitive methods for screening of animal faeces and environmental samples potentially contaminated by Toxocara eggs. In this work, a pre-analytical method for efficient extraction of DNA from Toxocara eggs in environmental samples was set up using our previously validated T.

Effect of Artificial Aging on Mechanical and Tribological Properties of CAD/CAM Composite Materials Used in Dentistry.

With easy-to-process 3D printing materials and fast production, the quality of dental services can be improved. In the conventional procedure, the dentist makes temporary crowns directly in the patient's mouth, e.g.

Molecular data reveal cryptic speciation and host specificity in Toxascaris leonina (Nematoda: Ascarididae).

Toxascaris leonina (Ascarididae) is a cosmopolitan and polyxenical parasite whose host are canids and felids. To date, molecular phylogenetic studies included toxascarid representatives collected only from dogs or felids, therefore the intra-species differences between T. leonina collected from different host species has not been noticed.

An augmented reality sign-reading assistant for users with reduced vision.

People typically rely heavily on visual information when finding their way to unfamiliar locations. For individuals with reduced vision, there are a variety of navigational tools available to assist with this task if needed. However, for wayfinding in unfamiliar indoor environments the applicability of existing tools is limited.

Using an Augmented Reality Device as a Distance-based Vision Aid-Promise and Limitations.

Significance: For people with limited vision, wearable displays hold the potential to digitally enhance visual function. As these display technologies advance, it is important to understand their promise and limitations as vision aids.

Purpose: The aim of this study was to test the potential of a consumer augmented reality (AR) device for improving the functional vision of people with near-complete vision loss.

Distribution and dynamics of soil contamination with Toxocara canis and Toxocara cati eggs in Poland and prevention measures proposed after 20 years of study.

The studies conducted in the years 1994-2013 allowed to determine the distribution of Toxocara spp. eggs in the soil of different types of urban and rural areas in Poland and to establish seasonal and multi-year dynamics of soil contamination with T. cati and T.

Differences in some developmental features between Toxoplasma gondii-seropositive and seronegative school children.

Knowledge about the influence of latent toxoplasmosis on development and general biological condition of children is scant and thus the aim of the present study was to investigate these aspects in some detail. We compare school children in rural area seropositive and seronegative to the apicomplexan parasite Toxoplasma gondii (Nicolle et Manceaux, 1908) in terms of their developmental age, body mass and body height, physical fitness and end-of-term grades. Additionally, we evaluated the risk factors of infection with T.

Potential risk of zoonotic infections in recreational areas visited by Sus scrofa and Vulpes vulpes. Case study--Wolin Island, Poland.

The relation between intestinal parasite prevalence in wild boars and red foxes and the sanitary condition of the soil in recreational estates were determined. The analysis was made based on 36 samples of boar faeces and 22 samples of fox faeces, collected in their habitat as well as 60 samples of soil from two recreational areas. Two methods were used for faecal samples--flotation and direct faecal smear; and flotation in NaNO3 for soil samples examination.

Helminths of hedgehogs, Erinaceus europaeus and E. roumanicus from Poznań region, Poland--coprological study.

Fecal samples from the hedgehogs, Erinaceus europaeus (15 samples) and E. roumanicus (44 samples) collected in the Poznań region of Poland were examined. Endoparasites were isolated using Sheather's flotation technique.

[A comparison of soil contamination with Toxocara canis and Toxocara cati eggs in rural and urban areas of Wielkopolska district in 2000-2005].

The aim of the studies was to compare the degree of soil contamination with Toxocara canis and T. cati eggs in rural and urban areas depending on time of sampling and type of places examined. Material and methods.

Citric acid cough threshold in patients with gastroesophageal reflux disease rises after laparoscopic fundoplication.

Background: It has been reported that antireflux surgery can diminish chronic cough due to gastroesophageal reflux disease (GERD) that is resistant to pharmacologic therapy. The aim of this study was the assessment of citric acid cough threshold (CACT) in patients with chronic cough due to GERD before and 3 months after laparoscopic Toupet fundoplication.

Methods: Thirty subjects (20 women and 10 men; median age, 45.

[Assessment of cough threshold in patients with gastroesophageal reflux disease].

The aim of this study was the assessment of citric acid cough threshold in patients with chronic cough due to GERD, confirmed by 24-hour esophageal pH- monitoring, with other reasons of chronic cough excluded. Thirty subjects with chronic cough due to GERD and 15 healthy volunteers underwent cough challenge with doubling concentrations of citric acid using Asthma Provocation System (Jaeger). The cough threshold was defined as the first concentration of citric acid that induced cough.
