Derangements in monoaminergic transmission in the substantia nigra with disturbed signaling in the hypothalamic-pituitary-adrenal axis are the major characteristics of Parkinson's disease (PD). It has been reported that the administration of hydrogen sulfide (H2S) is in practice to treat PD because of its redundant nature in regulating various neuronal signals. Hence, the current investigation was performed to evaluate the hypothesis that H2S might exert protective action via the inhibition of epigenetic histone acetylation. ⋯ Diversely, H2S exposure reversed these alterations with reduced HDAC activity. Further, PD rats treated with HDAC inhibitor showed a dramatic upsurge in the level of tyrosine hydroxylase, with a decreased level of glial fibrillary acidic protein, α-synuclein, tumor necrosis factor α, and other cytokines. Thus the results of the study suggest that H2S exerts protection via inhibition of HDAC.

This study aimed to investigate the preventive effects of oral administration of probiotics on the incidence and severity of atopic dermatitis (AD) in infants. ⋯ Adding probiotics could favor the establishment of the intestinal microecological balance in the neonatal period, thereby reducing the incidence of AD, decreasing the levels of serum immune indexes and alleviating the severity of the disease.

Percutaneous coronary interventions (PCI) in bifurcations are still challenging and are associated with higher risks of periprocedural complications as well as restenosis and stent thrombosis. The aim of this paper was to summarize 12 months of clinical results of the prospective, first-in-man registry assessing the BiOSS LIM C stent (Balton, Poland). ⋯ Our registry might suggest that PCI using the BiOSS LIM C in coronary bifurcations is feasible and might be an option for percutaneous revascularization.

The most common cause of death in patients with amyotrophic lateral sclerosis (ALS) is respiratory failure, often in the period of 2-5 years, with a small percentage of patients surviving up to 10 years or more. The aim of the study was to evaluate the significance of pulmonary function tests in prediction of mortality and definition of indications for noninvasive mechanical ventilation (NIMV). ⋯ Our study points to the significance of timely application and early start of NIMV in patients with ALS as an important approach to defer functional impairment, which would mean that the criteria, in our country, for application of these devices must be changed, not only regarding the value of current functional diagnostic tests used in everyday practice in patients with ALS but also in regard to the introduction of new diagnostic tests, such as sniff nasal inspiratory pressure and/or polysomnographic testing.

In recent years, studies have shown that GABA has a certain therapeutic effect on acute lung injury (ALI), but its specific mechanism has not been fully elucidated. The study was designed to investigate the protective effect and mechanism of γ-aminobutyric acid (GABA) on ALI induced by lipopolysaccharide (LPS) in mice. ⋯ GABA can effectively alleviate ALI induced by LPS in mice, and its effect may be related to the upregulation of type B receptors.
