60 children with atopic asthma were included to the doubleblind study, in order to compare Zaditen and Clemastine. The trial was completed after 12 weeks of treatment. The efficacy was evaluated on the basis of clinical observation, lung function measurements and laboratory data. The Zaditen was shown to have more beneficial clinical effect on studied group than Clemastine. The lung function measurements before and after treatment did not showed much difference, although a significant decrease of the nonspecific bronchial reactivity to histamine was observed in the group receiving Zaditen . This was observed shortly after beginning of the treatment up to 6 weeks. Zaditen sirup was well tolerated and the only side effect observed was a significant weight increase, which could be explained by the elevation of serum sodium ions concentration.

We assessed the validity, reliability, and transferability of gas exchange and ventilatory variables from two commonly used metabolic measurement systems (COSMED Quark and VO2Master Pro). Two identical devices from each system were independently connected to a metabolic simulator (VacuMed), and 2 min of steady-state data was recorded at simulated oxygen uptake (V̇O) of 1, 2, 3, and 4 L∙min achieved through minute ventilation (V̇) of 30, 60, 105, and 150 L∙min. Each metabolic analyzer recorded data three times for each "intensity" in a randomized order, and assessments were completed on two separate days.

Idiopathic pulmonary fibrosis (IPF) is a progressive and chronic interstitial lung disease characterized by irreversible loss of lung function and a poor prognosis. Type I collagen, a major component of the extracellular matrix, plays a central role in the pathogenesis of fibrosis and is considered a key molecular target for therapeutic intervention. While current anti-fibrotic therapies demonstrate limited efficacy in slowing disease progression, their clinical impact remains suboptimal due to poor pharmacokinetic properties and non-curative therapy.

Background: Proton pencil beam scanning (PBS) treatment planning for head and neck (H&N) cancers is a time-consuming and experience-demanding task where a large number of potentially conflicting planning objectives are involved. Deep reinforcement learning (DRL) has recently been introduced to the planning processes of intensity-modulated radiation therapy (IMRT) and brachytherapy for prostate, lung, and cervical cancers. However, existing DRL planning models are built upon the Q-learning framework and rely on weighted linear combinations of clinical metrics for reward calculation.

Low testosterone in middle-aged/older men contributes to accelerated vascular aging, including endothelial dysfunction. However, the mechanisms by which low testosterone affects endothelial dysfunction are not well understood. We sought to determine whether higher endothelin-1 (ET-1) levels are associated with reduced brachial artery flow-mediated dilation (FMD) in middle-aged/older men with low testosterone.
