Estimation of Lactate Thresholds, Aerobic Capacity and Recovery Rate from Muscle Oxygen Saturation in Highly Trained Speed Skaters and Healthy Untrained Individuals.

The main objective of this study was to compare lactate thresholds and aerobic capacity from a graded-intensity exercise test (GXT) for near-infrared spectroscopy measurements in healthy, untrained individuals and highly trained athletes. This study included 29 untrained students (13 females) and 27 highly trained speed skaters (13 females). A maximal effort GXT was performed on a cycloergometer.

Antibiotic Resistance and Virulence Profiles of Strains Isolated from Wild Birds in Poland.

Wild animals are increasingly reported as carriers of antibiotic-resistant and pathogenic bacteria including . However, the role of free-living birds as reservoirs for potentially dangerous microbes is not yet thoroughly understood. In our work, we examined strains from wild birds in Poland in relation to their antimicrobial agents susceptibility, virulence and phylogenetic affiliation.

The first case of in European pond turtle ( in the wild in Poland.

During standard parasitological dissection of 4 individuals of European pond turtle () (Linneaus, 1758) one nematode was found. In a morphological examination the parasite was identified as (Rudolphi, 1819) and confirmed by DNA analysis based on sequencing of the small subunit ribosomal RNA gene. The partial 18S rDNA gene was deposited to NCBI GenBank with the accession number MN629917.

Survival Training Effects on Oxidative Stress and Muscle Damage Biomarkers of Naval Cadets.

It is important for military commanders to know the extent of fatigue experienced by soldiers undergoing a long-term military training. This knowledge can enable them to determine the level of physical capabilities of soldiers. The present study aimed to evaluate changes in the level of chosen biochemical parameters in blood during the survival training of Polish Naval Academy cadets.

Assessment of the Levels of Oxidative Stress, Muscle Damage, and Psychomotor Abilities of Special Force Soldiers during Military Survival Training.

The aim of this study was to analyze the changes in biochemical markers of oxidative stress and muscle damage, as well as psychomotor abilities during a military survival training. The study included 15 soldiers of special unit (SU), that completed 48 h military survival training combined with sleep deprivation. Before the training (P1), after 24 h (P2), and after 48 h of training (P3), blood samples were taken to measure biochemical markers.

Changes in Coordination Motor Abilities of Naval Academy Cadets During Military Survival Training.

Armed conflicts tend to be unpredictable to such an extent that the fact that seamen also have to fight for their survival on land cannot be excluded. The aim of the study was to determine the degree of changes in selected coordination motor abilities in the course of a 36-h military survival training of Naval Academy cadets. There were 14 Polish Naval Academy cadets, ages 20-27 yr, who were examined 4 times: pretraining, after 24 h, posttraining, and after a 12-h rest.

Effects of a 36-h Survival Training with Sleep Deprivation on Oxidative Stress and Muscle Damage Biomarkers in Young Healthy Men.

The aim of this study was to analyze changes in oxidative stress and muscle damage markers during a 36-h survival training combined with sleep deprivation. The study included 23 male students of physical education (specialty: Physical Education for Uniformed Services), randomly divided into the survival or control group. The students in the survival group completed a 36-h survival training with moderate to low physical activity, without the possibility to sleep.

Osteochondral Repair Using Porous Three-dimensional Nanocomposite Scaffolds in a Rabbit Model.

Aim: To evaluate the utility of a novel nanocomposite biomaterial consisting of poly-L/D-lactide, and hydroxyapatite bioceramics, enriched with sodium alginate in articular cartilage defect treatment.

Materials And Methods: The biomaterial was prepared using the method of solvent casting and particle leaching. The study was conducted on 20 New Zealand White rabbits.

MALDI-TOF Mass Spectrometry as a Useful Tool for Identification of spp. from Wild Birds and Differentiation of Closely Related Species.

The aim of this study was to explore the accuracy and feasibility of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) in identifying bacteria from environmental sources, as compared with gene sequencing, and to evaluate the occurrence of bacteria of the genus in wild birds. In addition, a phyloproteomic analysis of certain species with spectral relationships was performed. The enterococci were isolated from 25 species of wild birds in central Europe (Poland).

Chemoenzymatic approach to optically active 4-hydroxy-5-alkylcyclopent-2-en-1-one derivatives: an application of a combined circular dichroism spectroscopy and DFT calculations to assignment of absolute configuration.

A series of representative optically active derivatives of 4-hydroxy-5-alkylcyclopent-2-en-1-one were prepared from the respective 2-furyl methyl carbinols via the Piancatelli rearrangement followed by the enzymatic kinetic resolution of racemates. Applicability of chiroptical methods (experimental and calculated electronic circular dichroism [ECD] and vibrational circular dichroism [VCD] spectra) to determine the absolute configuration of both stereogenic centers in 4-hydroxy-5-methylcyclopent-2-en-1-one was demonstrated. It was also demonstrated that the concurrent application of ECD and VCD spectroscopy can be used for the determination of the configuration of two stereogenic centers.

Mitochondrial D-loop mutations and polymorphisms are connected with canine malignant cancers.

Abstract The aim of the conducted investigations was to identify differences in the D-loop nucleotide sequence between neoplastic tissue, normal tissue, and blood and to determine their correlation with the type of cancer in dogs. In 62.5% of the analyzed tumors of epithelial origin and 25% tumors of mesenchymal origin, substitution was detected within the D-loop sequence between the neoplastic tissue, normal tissue, and blood.

Prevalence of yeasts in English full blood mares.

The aim of the study was a quantitative and qualitative analysis of microflora, presentation of current data about prevalence of the microflora on the skin and mucous membranes, and determination of its possible effect on reproduction of English full blood horses bred in Poland. The material for analyses was sampled from the skin and mucous membranes (385 samples) of 55 English full blood mares. Taking into account reproduction traits, the mares were classified into three groups.
