Plectinopathies are orphan diseases caused by gene mutations. is encoding the protein plectin, playing a role in linking cytoskeleton components in various tissues. In this study, we describe the clinical case of a 26-year-old patient with an early onset plectinopathy variant "limb-girdle muscle dystrophy type 2Q," report histopathological and ultrastructural findings in m.

Development of personalized skin treatment in medicine and skin care may benefit from simple and accurate evaluation of the fraction of senescent skin fibroblasts that lost their proliferative capacity. We examined whether enriched analysis of colonies formed by primary human skin fibroblasts, a simple and widely available cellular assay, could reveal correlations with the fraction of senescent cells in heterogenic cell population. We measured fractions of senescence associated β-galactosidase (SA-βgal) positive cells in either mass cultures or colonies of various morphological types (dense, mixed and diffuse) formed by skin fibroblasts from 10 human donors.

The only proven cure for Shwachman-Diamond syndrome (SDS) bone marrow failure is allogeneic hematopoietic stem cell transplantation (HSCT). However HSCT with donors other than HLA-identical siblings is associated with high mortality and unfavorable prognosis. This paper presents the first experience of HSCT treatment of SDS using an unaffected HLA-identical sibling produced through preimplantation genetic diagnosis (PGD).

To date, over 30 genes with mutations causing limb-girdle muscle dystrophy have been described. Dysferlinopathies are a form of limb-girdle muscle dystrophy type 2B with an incidence ranging from 1:1,300 to 1:200,000 in different populations. In 1996, Dr.

Difficulties related to the obtainment of stem/progenitor cells from skeletal muscle tissue make the search for new sources of myogenic cells highly relevant. Alveolar mucosa might be considered as a perspective candidate due to availability and high proliferative capacity of its cells. Human alveolar mucosa cells (AMC) were obtained from gingival biopsy samples collected from 10 healthy donors and cultured up to 10 passages.

Introduction: The effective treatment of chronic lower limb ischemia is one of the most challenging issues confronting vascular surgeons. Current pharmacological therapies play an auxiliary role and cannot prevent disease progression, and new treatment methods are needed. pl-VEGF165, a gene therapy drug, was approved in Russia for the treatment of atherosclerotic peripheral arterial disease (PAD) after clinical studies in 2011.

The authors share their experience in comprehensive conservative treatment of patients presenting with chronic lower limb ischaemia (CLLI) associated with atherosclerosis of peripheral arteries by means of the first Russian registered gene therapeutic agent "Neovasculgen" (plasmid with the vegf165 gene), analysing the long-term outcomes of treating a total of 45 patients with stage II and III CLLI according to the classification of Pokrovsky-Fontain. The patients were followed up for 5 years. Efficacy of treatment was assessed by registering the dynamics of the pain-free walking distance (PFWD), linear blood velocity (LBV), ankle-brachial index (ABI), as well as the limb salvage rate and survival of patients.

Treatment of patients with large bone defects is a complex clinical problem. We have initiated the first clinical study of a gene-activated bone substitute composed of the collagen-hydroxyapatite scaffold and plasmid DNA encoding vascular endothelial growth factor. The first patient with two nonunions of previously reconstructed mandible was enrolled into the study.

Presented herein are comparative remote results of combined surgical treatment of 121 patients with stage IIB-III lower limb chronic ischaemia (LLCI) by means of indirect revascularization (lumbar sympathectomy--LSE and revascularizing osteotrepanation of the tibial bone--ROT) and gene therapy using the first registered Russian gene therapeutic agent Neovasculgen®. Depending on the LLCI degree and the method of treatment, during 3 years we assessed such parameters as the limb salvage rate, pain-free walk distance (PFWD), ankle-brachial index (ABI) and linear blood velocity (LBV). An increase in the PFWD in patients with initial stage IIB LLCI in the group of gene therapy was considerably higher than in other types of treatment (p=0.

Hypotrichosis is an abnormal condition characterized by decreased hair density and various defects in hair structure and growth patterns. In particular, in woolly hair, hypotrichosis is characterized by a tightly curled structure and abnormal growth. In this study, we present a detailed comparative examination of individuals affected by autosomal-recessive hypotrichosis (ARH), which distinguishes two types of ARH.

Bone grafts are medical devices that are in high demand in clinical practice for substitution of bone defects and recovery of atrophic bone regions. Based on the analysis of the modern groups of bone grafts, the particularities of their composition, the mechanisms of their biological effects, and their therapeutic indications, applicable classification was proposed that separates the bone substitutes into "ordinary" and "activated." The main differential criterion is the presence of biologically active components in the material that are standardized by qualitative and quantitative parameters: growth factors, cells, or gene constructions encoding growth factors.

Biocompatible calcium phosphate ceramic grafts are able of supporting new bone formation in appropriate environment. The major limitation of these materials usage for medical implants is the absence of accessible methods for their patient-specific fabrication. 3D printing methodology is an excellent approach to overcome the limitation supporting effective and fast fabrication of individual complex bone substitutes.

Basic molecular mechanisms, associated with the main cell population of the dermis - fibroblasts - are the basis of skin aging. The number of functionally active fibroblasts in the skin and their biosynthetic activity decreases with age, thus enhancement of their cell density with synthetically active cells is accepted as a one of the most effective methods. The objective of the present study was to evaluate the safety and effectiveness of intradermal administration of autologous dermal fibroblasts in a year after treatment of 17 patients, aged 45-65 years.

Biocompatible ceramic fillers are capable of sustaining bone formation in the proper environment. The major drawback of these scaffolding materials is the absence of osteoinductivity. To overcome this limitation, bioengineered scaffolds combine osteoconductive components (biomaterials) with osteogenic features such as cells and growth factors.
