Trends in the incidence rates of lower limb amputation due to nondiabetic peripheral artery disease in a large industrial city in Western Siberia, Russia: A review from 1996 to 2019.

Background: lower limb amputation (LLA) is a growing problem in the population with and without diabetes mellitus. Monitoring the incidence rates of LLA is important for health care planning and has implications for the future problems of medical and social care.

Objective: This study aimed to determine the trends in incidence rates of LLA due to nondiabetic peripheral artery disease in Novokuznetsk, Western Siberia, Russia.

Using the interviewer-administered version of Work Rehabilitation Questionnaire (WORQ) in Russia: cross-cultural adaptation and psychometric properties in traumatic spinal cord injury.

Purpose: (1) To perform a cross-cultural adaptation of Work Rehabilitation Questionnaire to Russian (WORQ-R); (2) to report the psychometric properties of WORQ-R in patients with traumatic spinal cord injury (TSCI).

Materials And Methods: WORQ is designed to evaluate the work functioning of individuals who are engaged in vocational rehabilitation. We performed a formal cross-cultural adaptation of WORQ from English to Russian utilizing a standardized 3-step approach.

[Degradation of lignin-carbohydrate substrate by soil fungi--producers of laccase and cellobiose dehydrogenase].

The growth of nonsporulating mycelial fungi INBI 2-26(+), producer of laccase; INBI 2-26(-), producer of cellobiose dehydrogenase; and their mixed culture on lignin-carbohydrate substrates under conditions of submerged fermentation were studied. The degrees of degradation of lignin, cellulose, and hemicellulose of cut straw over 23 days amounted to 29.8, 51.

[Isolation and characterization of a cellobiose dehydrogenase formed by a asporogenic mycelial fungus INBI 2-26(-)].

A nonsporulating fungus isolated from dioxine-containing tropical soils forms cellobiose dehydrogenase, when grown in media supplemented by a source of cellulose. The enzyme purified to homogeneity by SDS-PAGE (yield, 43%) had an M(r) of 95 kDa; its pH optimum was in the range 5.5-7.

[Fungal decomposition of oat straw during liquid and solid state fermentation].

White rot fungi (Coriolus hirsutus, Coriolus zonatus, and Cerrena maxima from the collection of the Komarov Botanical Institute of the Russian Academy of Sciences) and filamentous fungi (Mycelia sterilia INBI 2-26 and Trichoderma reesei 6/16) were grown on oat straw-based liquid and solid media, as well as in a bench-scale reactor, either individually or as co-cultures. All fungi grew well on solid agar medium supplemented with powdered oat straw as the sole carbon source. Under these conditions, the mould Trichoderma reesei fully suppressed the growth of all basidiomycetes studied; conversely, Mycelia sterilia neither affected the development of any of the cultures, nor did it show any substantial susceptibility to suppression by their presence.

[The clinical picture and surgical treatment of the residual defects and deformities of the maxillary alveolar process after cheilo- and uranoplasty].

The authors have developed a new working classification of residual defects of the maxillary alveolar process, anterior segment of the hard palate and oronasal anastomosis, based on the results of cheilo- and uranoplasty in 125 patients. The choice of present-day methods of surgery is based on the suggested working classification scheme. The known methods of surgical management of the residual defects are described and new methods developed by the authors suggested, permitting an effective shortening of the terms of surgical rehabilitation and yielding stable functional and aesthetic results.

[Correlations between various cardiometric and functional parameters in dilated cardiomyopathy and alcoholic lesion of the heart (data of roentgenological and echocardiographic studies)].

Volumetric changes of the heart and its left ventricle, as well as myocardial contractility were assessed in 50 patients with dilatation cardiomyopathy (DCMP) and 16 patients with acute alcoholic heart damage (AHD), on the basis of roentgenologic (cardiac shape and volume, left ventricular and aortic pulsation, respiratory volumetric variations, pulmonary circulation) and echocardiographic (end-diastolic size and volume, systolic increment of posterior wall thickness, ejection fraction and left-ventricular shortening) data. Both DCMP and acute AHD were shown to be associated with total enlargement of the heart, diffuse impairment of myocardial contractility, considerably depressed left ventricular pumping function, early congestion in the systemic circulation network coupled with minor roentgenologic signs of congestion in pulmonary circulation.
