    Nowadays higher education programs quality in Belarus allows the republic to prepare well-competent specialists in various fields. The curriculum and whole atmosphere in community and at the university campus are making great influence on efficiency of studying. Furthermore, living environment, where non-resident students hold most of their time, is important, because it is where basic human needs for food, rest and communication are being fulfilled

    © 2017 Tatiana I. Eliseeva et al. Influence of bronchial asthma (BA) severity on physical development in children patients was evaluated in comparison with healthy population. Materials and Methods. 1042 children and adolescents (768 boys) with atopic BA were evaluated. All children underwent standard examination in a clinical setting, including anthropometry. The control group included 875 healthy children of a comparable age (423 boys). Results. The fraction of patients with the normal, lower, and increased height among the whole group of patients with BA is close to the corresponding values in the healthy population (χ 2 =3.32, p=0.65). The fraction of BA patients with the reduced physical development is increased monotonically and significantly when the BA severity increases: healthy group, 8.2% (72/875), BA intermittent, 4.2% (6/144), BA mild persistent 9% (47/520), BA moderate persistent, 11.7% (36/308), and BA severe persistent, 24.3% (17/70) (χ 2 =45.6, p=0,0009). Conclusion. The fraction of the children with the reduced height is increased monotonically and significantly in the groups of increasing BA severities. At the same time, the fraction of such children in groups of intermittent and mild persistent BA practically does not differ from the conditionally healthy peers

    © 2017, Nizhny Novgorod State Medical Academy. All rights reserved.The aim of the investigation was to estimate the possibilities of using relative body mass index (RBMI) for determining age- and gender-specific aspects of nutritional status in children and adolescents with bronchial asthma (BA) of different severity degrees. Materials and Methods. The study involved 887 children and adolescents with BA of different severities, aged 5–17 years (61– 215 months), of them 655 were boys. Their body mass index (BMI) was evaluated based on the Z-score criterion and nutritional status was determined as recommended by the World Health Organization (WHO). To unify nutritional status assessment in patients of different age and gender groups, there was introduced RBMI representing the ratio of the patient’s BMI to gender- and age-specific median BMI value presented in the WHO reference data. Results. Nutritional status and its relation to BA were studied in children and adolescents using two parameters: the standard nutritional status indicator based on BMI Z-scores as recommended by WHO, and a new parameter, RBMI, representing the ratio of the patient’s BMI to gender- and age-specific median BMI value recommended by WHO. No significant nutritional status differences were found in the studied sample of patients with various degrees of BA severity. There was revealed a tendency to a decrease in the proportion of children with normal body weight and an increase in the proportion of overweight children as BA severity increased, χ2=26.82; р=0.08. Conclusion. Using RBMI for assessment of BA patients makes it possible to significantly facilitate clinical data analysis and obtain new data unavailable when standard parameters are applied

    Endonasal infrared thermometry for the diagnosis of allergic inflammation of the nasal mucosa in patients with bronchial asthma

    © 2017, Nizhny Novgorod State Medical Academy. All rights reserved. Bronchial asthma (BA) is often associated with chronic inflammatory processes in the nasal mucosa; these processes give rise to allergic rhinitis, chronic rhinosinusitis, adenoiditis, and polypous rhinosinusitis. Due to their multiple symptoms, these diseases of the upper respiratory tract, especially allergic rhinitis, are often difficult to verify in patients with asthma. The aim of the study was to evaluate the diagnostic potential of endonasal IR thermometry in BA patients suspected of allergic rhinitis. Materials and Methods. Fifty children diagnosed with both BA and allergic rhinitis and 15 healthy children, matched by gender and age, participated in the study. The endonasal temperature determined with contactless IR thermometry was confronted with the symptoms of allergic rhinitis and sinusitis assessed with the TNSS and SNOT-20 questionnaires. The results were compared with the severity of nasal obstruction as determined through the anterior active rhinomanometry. Results. The nasal temperature in patients with asthma and allergic rhinitis was 33.77 [33.37; 34.17]°С, which was significantly lower than that in the group of healthy children (34.98 [34.57; 35.39] °С; p=0.0006); the body temperature did not differ between the groups (36.55 [36.45; 36.65] and 36.58 [36.40; 36.76] °С, respectively; p=0.5). We found a negative correlation between the values of nasal temperature and the sinusitis symptom scores in patients with BA and allergic rhinitis (R=–0.32; p=0.02). Conclusion. Patients with both BA and allergic rhinitis showed a decreased endonasal temperature in comparison with healthy children; the endonasal temperature can serve an indicator of allergic inflammation of the nasal mucosa

    Metal organic framework nanosheets in polymer composite materials for gas separation

    Full text link
    [EN] Composites incorporating two-dimensional nanostructures within polymeric matrices have potential as functional components for several technologies, including gas separation. Prospectively, employing metal-organic frameworks (MOFs) as versatile nanofillers would notably broaden the scope of functionalities. However, synthesizing MOFs in the form of freestanding nanosheets has proved challenging. We present a bottom-up synthesis strategy for dispersible copper 1,4-benzenedicarboxylate MOF lamellae of micrometre lateral dimensions and nanometre thickness. Incorporating MOF nanosheets into polymer matrices endows the resultant composites with outstanding CO2 separation performance from CO2/CH4 gas mixtures, together with an unusual and highly desired increase in the separation selectivity with pressure. As revealed by tomographic focused ion beam scanning electron microscopy, the unique separation behaviour stems from a superior occupation of the membrane cross-section by the MOF nanosheets as compared with isotropic crystals, which improves the efficiency of molecular discrimination and eliminates unselective permeation pathways. This approach opens the door to ultrathin MOF-polymer composites for various applications.The research leading to these results has received funding (J.G., B.S.) from the European Research Council under the European Union’s Seventh Framework Programme (FP/2007-2013)/ERC Grant Agreement no. 335746, CrystEng-MOF-MMM.

    Das Ziel dieser Doktorarbeit ist die Herstellung von funktionellen Materialien (Pulver und Schichten) basierend auf porösen Metall-Organischen Gerüsten (MOFs). Die neuartige Methode, welche in Kapitel 3 beschrieben ist, beruht auf der Fabrikation von MOF Materialien aus anorganischen Metalloxiden. Dieses Verfahren ermöglicht die präzise Kontrolle der MOF Kristallbildung. Kapitel 4 beschreibt die erfolgreiche Herstellung von dünnen porösen MOF Schichten aus den vorgeformten Metalloxiden auf der Oberfläche von verschiedenen Substraten. Das Abscheiden von Metalloxiden auf Substratoberflächen basiert auf der Methode der Atomlagenabscheidung (ALD) und Sputtering. Kapitel 5 beschäftigt sich mit der "umgekehrten" Fabrikation von funktionalen Metalloxiden aus porösen MOF Materialien als Vorlage. Des Weiteren wurden die funktionelle MOF- und Metalloxid-Verbindungen für verschiedene Anwendungen erfolgreich getestet
