Abstract
OBJECTIVE To describe a novel transbronchial cryobiopsy technique for mediastinal lesions after initial ultrasound assessment and EBUS-TBNA. MATERIAL AND METHODS Transbronchial cryobiopsy (TBCB) was performed in 35 patients with suspicious mediastinal lesions between November 2020 and September 2022. Age of patients ranged from 22 to 75 years (median 50 [39; 62]). Men-to-women ratio was 13:22. RESULTS According to morphological data, patients with sarcoidosis (n=13), NSCLC (n=7) and metastases of other tumors (n=3) prevailed. There were patients with B-cell lymphoma (n=1), Castleman disease (n=1) and small cell lung cancer (n=2). Among 15 biopsies for immunohistochemical examination, samples were sufficient for final morphological conclusion in 11 (73.3%) cases (95% CI 48.5-89.1). In 4 (11.4%) cases (95% CI 4.5-26), examination was uninformative. Repeated biopsy was performed in 2 cases, and sarcoidosis of thoracic lymph nodes was confirmed. Sensitivity, specificity and accuracy of transbronchial cryobiopsy were 93.3, 100 and 94%, respectively. There were no clinically significant complications. In one case, chest X-ray revealed pneumomediastinum without need for additional treatment. CONCLUSION Transbronchial mediastinal cryobiopsy is a perspective method for diagnosis of mediastinal neoplasms. Apparently, this approach may be advisable in patients with suspected sarcoidosis or lymphoproliferative diseases.

Abstract
BACKGROUND The development of regenerative therapy for human spinal cord injury (SCI) is dramatically restricted by two main challenges: the need for a safe source of functionally active and reproducible neural stem cells and the need of adequate animal models for preclinical testing. Direct reprogramming of somatic cells into neuronal and glial precursors might be a promising solution to the first challenge. The use of non-human primates for preclinical studies exploring new treatment paradigms in SCI results in data with more translational relevance to human SCI.
AIM To investigate the safety and efficacy of intraspinal transplantation of directly reprogrammed neural precursor cells (drNPCs).
METHODS Seven non-human primates with verified complete thoracic SCI were divided into two groups: drNPC group (n = 4) was subjected to intraspinal transplantation of 5 million drNPCs rostral and caudal to the lesion site 2 wk post injury, and lesion control (n = 3) was injected identically with the equivalent volume of vehicle.
RESULTS Follow-up for 12 wk revealed that animals in the drNPC group demonstrated a significant recovery of the paralyzed hindlimb as well as recovery of somatosensory evoked potential and motor evoked potential of injured pathways. Magnetic resonance diffusion tensor imaging data confirmed the intraspinal transplantation of drNPCs did not adversely affect the morphology of the central nervous system or cerebrospinal fluid circulation. Subsequent immunohistochemical analysis showed that drNPCs maintained SOX2 expression characteristic of multipotency in the transplanted spinal cord for at least 12 wk, migrating to areas of axon growth cones.
CONCLUSION Our data demonstrated that drNPC transplantation was safe and contributed to improvement of spinal cord function after acute SCI, based on neurological status assessment and neurophysiological recovery within 12 wk after transplantation. The functional improvement described was not associated with neuronal differentiation of the allogeneic drNPCs. Instead, directed drNPCs migration to the areas of active growth cone formation may provide exosome and paracrine trophic support, thereby further supporting the regeneration processes.

Abstract
We have designed a novel two-component matrix (SPRPix) for the encapsulation of directly reprogrammed human neural precursor cells (drNPC). The matrix is comprised of 1) a solid anisotropic complex scaffold prepared by electrospinning a mixture of recombinant analogues of the spider dragline silk proteins - spidroin 1 (rS1/9) and spidroin 2 (rS2/12) - and polycaprolactone (PCL) (rSS-PCL), and 2) a "liquid matrix" based on platelet-rich plasma (PRP). The combination of PRP and spidroin promoted drNPC proliferation with the formation of neural tissue organoids and dramatically activated neurogenesis. Differentiation of drNPCs generated large numbers of βIII-tubulin and MAP2 positive neurons as well as some GFAP-positive astrocytes, which likely had a neuronal supporting function. Interestingly the SPRPix microfibrils appeared to provide strong guidance cues as the differentiating neurons oriented their processes parallel to them. Implantation of the SPRPix matrix containing human drNPC into the brain and spinal cord of two healthy Rhesus macaque monkeys showed good biocompatibility: no astroglial and microglial reaction was present around the implanted construct. Importantly, the human drNPCs survived for the 3 month study period and differentiated into MAP2 positive neurons. Tissue engineered constructs based on SPRPix exhibits important attributes that warrant further examination in spinal cord injury treatment.

Abstract
Background Nonhuman primates (NHP) may provide the most adequate (in terms of neuroanatomy and neurophysiology) model of spinal cord injury (SCI) for testing regenerative therapies, but bioethical considerations exclude their use in severe SCI. New Method A reproducible model of SCI at the lower thoracic level has been developed in Rhesus macaques. The model comprises surgical resection of 25% of the spinal cord in the projection of the dorsal funiculus and dorsolateral corticospinal pathways, controlled via registration of intraoperative evoked potentials (EPs). The animals were evaluated using the modified Hindlimb score, MRI, SSEP, and MEP over a time period of 8-12 weeks post-SCI, followed by histological examination. Results Complete disappearance of intraoperative EPs from distal hindlimb muscles without restoration within two weeks post-SCI was an indicator for irreversible disruption of the abovementioned pathways. As a result, controlled damage to the spinal cord was achieved in three NHPs, clinically manifested as irreversible lower monoplegia. No significant functional restoration was observed in these NHPs up to 12 weeks post-SCI. Demyelination of the damaged ascending tracts was detected. Disturbances in pelvic organ function were not observed in all animals. Comparison with existing methods The new method of EPs-guided SCI allows a more controlled and irreversible damage to the spinal cord compared with contusion and other transection approaches. Conclusions This method to induce complete SCI in NHP is well tolerated, reproducible and ethically acceptable: these are valuable attributes in a preclinical model that will hopefully help advance testing of new regenerative therapies in SCI.

Abstract
Background The association of type 2 diabetes mellitus (T2DM) with the KCNJ11, CDKAL1, SLC30A8, CDKN2B, and FTO genes in the Russian population has not been well studied. In this study, we analysed the population frequencies of polymorphic markers of these genes. Methods The study included 862 patients with T2DM and 443 control subjects of Russian origin. All subjects were genotyped for 10 single nucleotide polymorphisms (SNPs) of the genes using real-time PCR (TaqMan assays). HOMA-IR and HOMA-β were used to measure insulin resistance and β-cell secretory function, respectively. Results The analysis of the frequency distribution of polymorphic markers for genes KCNJ11, CDKAL1, SLC30A8 and CDKN2B showed statistically significant associations with T2DM in the Russian population. The association between the FTO gene and T2DM was not statistically significant. The polymorphic markers rs5219 of the KCNJ11 gene, rs13266634 of the SLC30A8 gene, rs10811661 of the CDKN2B gene and rs9465871, rs7756992 and rs10946398 of the CDKAL1 gene showed a significant association with impaired glucose metabolism or impaired β-cell function. Conclusion In the Russian population, genes, which affect insulin synthesis and secretion in the β-cells of the pancreas, play a central role in the development of T2DM.

Abstract
The increase in diabetes was noted at the turn of the 21st century. Patients with type 2 diabetes (T2DM) make up the majority of patients. Diabetes is a multifactorial disease. It arises from adverse effects of environmental factors on the body of genetically susceptible peoples. According to modern concepts, T2DM is a polygenic disease. Each of the involved genes contributes to the risk of developing of this disease. In our study, the association between polymorphic genetic markers rs7756992, rs9465871, rs7754840, and rs10946398 in the CDKAL1 gene and rs1111875 in the HHEX/IDE locus and T2DM in the Russian population were studied. Four hundred forty patients with type 2 diabetes and 264 healthy individuals without any signs of the disease were examined. The comparative analysis of distribution of genotypes and allele frequencies points to an association between polymorphic genetic markers rs7756992, rs9465871, and rs10946398 in the CDKAL1 gene and this disease. For the other polymorphic genetic markers (rs7754840 in the CDKAL1 gene and rs1111875 in the HHEX/IDE locus), no statistically significant associations are found. On the basis of these data, we can conclude that the CDKAL1 gene is associated with development of T2DM. For the HHEX/IDE locus, such an association is absent.
