Mucopolysaccharidosis (MPS) is a rare genetic disease involving active storage of glycosaminoglycans (GAGs). Accumulation of GAGs in the connective tissues of airways leads to progressive pulmonary dysfunction. Studies conducted in Taiwan revealed mainly restrictive pulmonary dysfunction, whereas the same studies in Egypt and California revealed obstructive pulmonary dysfunction. The contradictory results and lack of studies of respiratory system in patients with MPS in Asian populations are an indication to study pulmonary impairment in patients with MPS in Kazakhstan. The prospective study of respiratory system in patients with MPS was conducted in the Scientific Centre of Paediatrics and Paediatric Surgery. Patients with MPS ( = 11) were examined for respiratory function. Different types of pulmonary dysfunction were present in MPS patients, they were mainly of a restrictive pathology. One patient with MPS II had obstructive dysfunction. Enzyme replacement therapy was provided for an average duration of four years, leading to improvements in respiratory function in two patients with total normalization in one. All observed patients had respiratory dysfunction, mainly of the restrictive type. Pulmonary impairment in patients with MPS is the main reason for death. Thus, it is necessary to follow up with pulmonary function assessments in children with MPS.

Prognostic analysis of acute type A aortic dissection after different surgical interventions: a cohort study.

Background: Acute type A aortic dissection (ATAAD) requires emergency surgery, but the choice of primary surgery remains controversial. It is believed that simple ascending aorta replacement may lead to higher postoperative survival rate, while the Sun procedure [frozen elephant trunk (FET) + total arch replacement (TAR)] performed in the first stage may obtain better long-term results. The study aimed to compare the outcome of ATAAD patients who underwent the Sun procedure with those without TAR + FET.

Background: Myofascial pain syndrome MPS is one of the most common causes of chronic musculoskeletal pain. It clinically presents with hypersensitive points in the muscle called "trigger points". Most of the time it remains undiagnosed/undertreated and this leads to severity in symptoms.

The relative contributions of nutrients, hyperinsulinemia, hormones, inflammation, and other cues are difficult to parse as they are convoluted by interplay between the local and systemic events. Here, we used a well-established human liver microphysiological system (MPS) to establish a physiologically-relevant insulin-responsive metabolic baseline and probe how primary human hepatocytes respond to controlled perturbations in insulin, glucose, and free fatty acids (FFAs).

Background: Mucus plugging has been identified as an important feature of severe asthma contributing to airway obstruction and disease severity. Recently, improvement of mucus plugging has been found upon treatment with several biologic therapies.
Objective: We aimed to analyze associations of baseline characteristic with mucus plugging score (MPS) and asked whether MPS at baseline predicts the clinical and functional response to biologic treatment in patients with severe asthma.

Organ-on-a-chip systems, also referred to as microphysiological systems (MPS), represent an advance in bioengineering microsystems designed to mimic key aspects of human organ physiology and function. Drawing inspiration from the intricate and hierarchical architecture of the human body, these innovative platforms have emerged as invaluable in vitro tools with wide-ranging applications in drug discovery and development, as well as in enhancing our understanding of disease physiology. The facility to replicate human tissues within physiologically relevant three-dimensional multicellular environments empowers organ-on-a-chip systems with versatility throughout different stages of the drug development process.
