TRPV4 antagonist GSK2193874 does not modulate cough response to osmotic stimuli.

Osmolarity changes of airway superficial fluid are associated with cough and are used in research. TRPV4 is calcium channel initially described as osmosensor. In the airways, it can play role in increasing cough reflex sensitivity.

Genetic and Environmental Biomarkers Associated with Triglyceride Levels in Two Groups of Slovak Women.

Objective: This study analyzed the association between the MLXIPL gene polymorphism (rs3812316) and triglyceride (TG) levels and selected environmental biomarkers in Slovak women at risk for cardiovascular disease compared to a reference sample.

Materials And Methods: The studied sample consisted of 200 women at cardiovascular risk (mean age 52.96 ± 6.

Methylation in promoter regions of PITX2 and RASSF1A genes in association with clinicopathological features in breast cancer patients.

Breast cancer is a heterogeneous disease with very different responses to therapy and different length of survival. In many cases, however, the determination of the stage and histopathological characteristics of breast cancer is insufficient to predict prognosis and response to treatment for the vast heterogeneity of the disease. To understand the molecular signature of subtypes of breast cancer, we attempted to identify the methylation status of key tumour suppressor gene Ras association (RalGDS/AF-6) domain family member 1 isoform a (RASSF1A) and a member of the paired-like homeodomain transcription factor family which functions in left-right asymmetry development (PITX2) and to correlate results with known clinicopathological features of breast cancer.

The complexity of electrodermal activity is altered in mental cognitive stressors.

The aim of this study was to evaluate potential changes in the electrodermal activity (EDA) to enable the detection of variations in the sympathetic nervous system during mental load and recovery period. Several EDA parameters were used: SCA (skin conductance amplitude), frequency of NS-EDR (nonspecific electrodermal responses), SIE (symbolic information entropy), and ApEn (approximate entropy). The cohort consisted of 50 healthy students (average age: 23.

Cardiac Vagal Control and Depressive Symptoms in Response to Negative Emotional Stress.

We aimed to study complex cardiovagal control using heart rate variability (HRV), linear and nonlinear analyses at rest and during negative emotional stress in healthy students with varying depressive symptoms. ECG recording in 20 students was performed at baseline, negative emotional stress, and recovery period. The HRV parameters evaluated were the following: RR interval, spectral power in high-frequency band (HF-HRV), and symbolic dynamics index 2LV%.

Symbolic dynamics of heart rate variability - a promising tool to investigate cardiac sympathovagal control in attention deficit/hyperactivity disorder (ADHD)?

We aimed to evaluate complex cardiac sympathovagal control in attention deficit/hyperactivity disorder (ADHD) by using heart rate variability (HRV) nonlinear analysis - symbolic dynamics. We examined 29 boys with untreated ADHD and 25 healthy boys (age 8-13 years). ADHD symptoms were evaluated by ADHD-RS-IV scale.
