The Recombinant Oncolytic Virus VV-GMCSF-Lact and Chemotherapy Drugs against Human Glioma.

Virotherapy is one of the perspective technologies in the treatment of malignant neoplasms. Previously, we have developed oncolytic vaccinia virus VV-GMCSF-Lact and its high cytotoxic activity and antitumor efficacy against glioma was shown. In this work, using immortalized and patient-derived cells with different sensitivity to VV-GMCSF-Lact, we evaluated the cytotoxic effect of chemotherapy agents.

Transcriptome Changes in Glioma Cells upon Infection with the Oncolytic Virus VV-GMCSF-Lact.

Oncolytic virotherapy is a rapidly evolving approach that aims to selectively kill cancer cells. We designed a promising recombinant vaccinia virus, VV-GMCSF-Lact, for the treatment of solid tumors, including glioma. We assessed how VV-GMCSF-Lact affects human cells using immortalized and patient-derived glioma cultures and a non-malignant brain cell culture.

MicroRNAs in the Diagnosis of Malignancy of Supratentorial Brain Gliomas and Prognosis of Disease Progression.

Introduction: The study of brain tumors has shown that microRNAs can act as both oncogenes and tumor suppressors and, consequently, can be used as biomarkers for the diagnosis and prognosis of such tumors. Thus, big interest arises in the role of microRNA and its part in oncogenesis in the human brain to find key molecules that can act as tumor markers for diagnostic and prognostic purposes, as well as potential therapeutic agents.

Study Aim: The sim of this study was to assess histological, molecular, and genetic metrics in patients with supratentorial gliomas, and indicate diagnostic and prognostic abilities of microRNA usage as biomarkers of the grade of malignancy of the tumor.

Discovering Glioma Tissue through Its Biomarkers' Detection in Blood by Raman Spectroscopy and Machine Learning.

The most commonly occurring malignant brain tumors are gliomas, and among them is glioblastoma multiforme. The main idea of the paper is to estimate dependency between glioma tissue and blood serum biomarkers using Raman spectroscopy. We used the most common model of human glioma when continuous cell lines, such as U87, derived from primary human tumor cells, are transplanted intracranially into the mouse brain.

MicroRNA and mRNA Expression Changes in Glioblastoma Cells Cultivated under Conditions of Neurosphere Formation.

Glioblastoma multiforme (GBM) is one of the most highly metastatic cancers. The study of the pathogenesis of GBM, as well as the development of targeted oncolytic drugs, require the use of actual cell models, in particular, the use of 3D cultures or neurospheres (NS). During the formation of NS, the adaptive molecular landscape of the transcriptome, which includes various regulatory RNAs, changes.

Transcriptome Changes in Glioma Cells Cultivated under Conditions of Neurosphere Formation.

Glioma is the most common and heterogeneous primary brain tumor. The development of a new relevant preclinical models is necessary. As research moves from cultures of adherent gliomas to a more relevant model, neurospheres, it is necessary to understand the changes that cells undergo at the transcriptome level.

Antibiotic Resistance and Pathogenomics of Circulating in Novosibirsk, Russia.

A total of 394 strains of staphylococci found in humans and pets in Novosibirsk, Siberian Russia, were characterized in terms of antibiotic resistance and corresponding genes. Two coagulase-positive and 17 coagulase-negative species were identified. The majority of isolates, with the exception of and hospital isolates, were sensitive to most of the tested antibiotics, and isolates from pets displayed the lowest level of resistance.

Double Recombinant Vaccinia Virus: A Candidate Drug against Human Glioblastoma.

Glioblastoma is one of the most aggressive brain tumors. Given the poor prognosis of this disease, novel methods for glioblastoma treatment are needed. Virotherapy is one of the most actively developed approaches for cancer therapy today.

[Features of surgical treatment of urinary incontinence in women with urethral destruction].

Urethral destruction in women is a rare pathology which is result of traumatic damage of the urethra during pelvic fractures, sexual trauma, iatrogenic effects (operative vaginal delivery, prolonged catheterization of the bladder, complicated surgical interventions on the urethra, etc.). The main symptom of urethral destruction is involuntary urinary incontinence.

[Penile angiomyxoma: a case report].

Angiomyxoma is a rare benign tumor prone to aggressive and invasive growth and relapse. Very few case reports of tumors with this morphology have been published in the world literature. In this paper, we report a rare case of penile angiomyxoma, which illustrates that any preoperative examination does not allow physicians to suspect this tumor type.

[Results of surgical treatment for lumbar spine segmental instability].

Aim: To perform a comparative analysis of outcomes in patients with lumbar spine segmental instability who underwent surgical treatment using transforaminal lumbar interbody fusion (TLIF) and direct lateral interbody fusion (DLIF) techniques.

Material And Methods: The multicenter study involved 209 patients who underwent surgery for lumbar spine segmental instability. Long-term outcomes (up to 2 years) were studied in 134 patients: patients of the first group (98 patients) underwent traditional transforaminal lumbar interbody fusion (TLIF) and transpedicular stabilization of vertebral segments; patients of the second group (36 patients) underwent direct lateral interbody fusion (DLIF) in combination with transpedicular stabilization of the lumbar vertebral segments.
