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.

Challenges to extracting spatial information about double P dopants in Si from STM images.

The design and implementation of dopant-based silicon nanoscale devices rely heavily on knowing precisely the locations of phosphorous dopants in their host crystal. One potential solution combines scanning tunneling microscopy (STM) imaging with atomistic tight-binding simulations to reverse-engineer dopant coordinates. This work shows that such an approach may not be straightforwardly extended to double-dopant systems.

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.

Parametric Description of EEG Profiles for Assessment of Sleep Architecture in Disorders of Consciousness.

We propose a fully parametric approach to the assessment of sleep architecture, based upon the classical electroencephalographic criteria, applicable also to the recordings of patients with disorders of consciousness (DOC). Sleep spindles and slow waves are automatically detected from the matching pursuit decomposition of overnight EEG recordings. Their evolution can be presented in the form of EEG profiles, yielding a continuous description of sleep architecture, compatible with the classical criteria used in sleep staging.

Assessment of Statistically Significant Command-Following in Pediatric Patients with Disorders of Consciousness, Based on Visual, Auditory and Tactile Event-Related Potentials.

Disorders of consciousness (DOC) are among the major challenges of contemporary medicine, mostly due to the high rates of misdiagnoses in clinical assessment, based on behavioral scales. This turns our attention to potentially objective neuroimaging methods. Paradigms based on electroencephalography (EEG) are most suited for bedside applications, but sensitive to artifacts.

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.

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).

Unilateral flank ovariohysterectomy in guinea pigs (Cavia porcellus).

Aims: To describe a simple, minimally invasive method of ovariohysterectomy via a unilateral flank approach in guinea pigs, for use in routine desexing of healthy female guinea pigs or treatment of ovarian cysts.

Methods: The subjects of this retrospective study were 41 client-owned guinea pigs submitted for routine desexing or treatment of ovarian cysts. They included 16 healthy female guinea pigs aged 8-12 months (Group 1), and 15 females aged from 9 months to 3 years (Group 2), and 10 females aged from 3 to 7 years (Group 3) with different-sized ovarian cysts.

Spindles in Svarog: framework and software for parametrization of EEG transients.

We present a complete framework for time-frequency parametrization of EEG transients, based upon matching pursuit (MP) decomposition, applied to the detection of sleep spindles. Ranges of spindles duration (>0.5 s) and frequency (11-16 Hz) are taken directly from their standard definitions.

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.
