Next-Generation Sequencing-Based Monitoring of Intestinal Bacteria and Bacteriophages Following Fecal Microbiota Transplantation in Inflammatory Bowel Diseases.

Inflammatory bowel diseases (IBD) and acute graft-versus-host disease (GVHD) are associated with persistent intestinal dysfunction preceded by gut bacterial dysbiosis. There are limited data on intestinal bacteriophages in these conditions. The aim of the present work was to detect associations between dominant intestinal bacteria by means of 16S rRNA gene sequencing, and some clinically significant viruses detected with a customized primer panel for NGS-based study.

Unraveling viral drug targets: a deep learning-based approach for the identification of potential binding sites.

The coronavirus disease 2019 (COVID-19) pandemic has spurred a wide range of approaches to control and combat the disease. However, selecting an effective antiviral drug target remains a time-consuming challenge. Computational methods offer a promising solution by efficiently reducing the number of candidates.

Control of the antitumour activity and specificity of CAR T cells via organic adapters covalently tethering the CAR to tumour cells.

On-target off-tumour toxicity limits the anticancer applicability of chimaeric antigen receptor (CAR) T cells. Here we show that the tumour-targeting specificity and activity of T cells with a CAR consisting of an antibody with a lysine residue that catalytically forms a reversible covalent bond with a 1,3-diketone hapten can be regulated by the concentration of a small-molecule adapter. This adapter selectively binds to the hapten and to a chosen tumour antigen via a small-molecule binder identified via a DNA-encoded library.

Open surgery: Still a great option to treat patients with post-traumatic arteriovenous fistulas: A case report.

Background: In the modern era of endovascular surgery percutaneous interventions are being widely used to treat a number of vascular disorders including arteriovenous fistulas (AVF). Still, patients with hostile anatomy or complicated cases such as large post-traumatic AVFs may be successfully treated using conventional vascular surgery.

Case Summary: This paper presents state-of-the-art treatment options in subjects with post-traumatic AVFs and a case-report of a successful open surgical approach in a patient with a 25 year old history of a post-traumatic AVF between the common femoral artery and common femoral vein.

Perioperative coagulation activation after permanent pacemaker placement.

Background: Bradyarrhythmias are typically treated with permanent pacemakers (PM). The elimination of bradyarrhythmia by PM implantation improves the patient's quality of life and prognosis, but it can also result in a number of sequalae. It is still unclear how PM implantation affects the hemostasis system's parameters and how such parameters relate to different consequences after PM placement.

The Telomeric Repeats of HHV-6A Do Not Determine the Chromosome into Which the Virus Is Integrated.

Human herpes virus 6A (HHV-6A) is able to integrate into the telomeric and subtelomeric regions of human chromosomes representing chromosomally integrated HHV-6A (ciHHV-6A). The integration starts from the right direct repeat (DR) region. It has been shown experimentally that perfect telomeric repeats (pTMR) in the DR region are required for the integration, while the absence of the imperfect telomeric repeats (impTMR) only slightly reduces the frequency of HHV-6 integration cases.

Comprehensive assessment of markers of apoptosis and cell proliferation during progression of atherosclerosis after surgery in patients with peripheral arterial disease.

Background: Determination of predictors that can affect development of atherosclerosis progression in the postoperative period is an urgent problem in vascular surgery.

Objectives: Integrated assessment of markers of apoptosis and cell proliferation in atherosclerotic lesions and their progression after surgery in patients with peripheral arterial diseases.

Methods: The investigation included 30 patients with stage IIB-III peripheral arterial disease.

Clinical and Genetic Characteristics of Pediatric Patients with Hypophosphatasia in the Russian Population.

(1) Hypophosphatasia (HPP) is a rare inherited disease caused by mutations (pathogenic variants) in the ALPL gene which encodes tissue-nonspecific alkaline phosphatase (TNSALP). HPP is characterized by impaired bone mineral metabolism due to the low enzymatic activity of TNSALP. Knowledge about the structure of the gene and the features and functions of various ALPL gene variants, taking into account population specificity, gives an understanding of the hereditary nature of the disease, and contributes to the diagnosis, prevention, and treatment of the disease.

Switchable targeting of solid tumors by BsCAR T cells.

The development of chimeric antigen receptor (CAR) T cell therapy has become a critical milestone in modern oncotherapy. Despite the remarkable in vitro effectiveness, the problem of safety and efficacy of CAR T cell therapy against solid tumors is challenged by the lack of tumor-specific antigens required to avoid on-target off-tumor effects. Spatially separating the cytotoxic function of CAR T cells from tumor antigen recognition provided by protein mediators allows for the precise control of CAR T cell cytotoxicity.

EVAR as a treatment option for high-risk nonagenarians with complicated abdominal aortic aneurysms.

Abdominal aortic aneurysm (AAA) is a life-threatening disease, with an extremely high risk of death when ruptured. With the increase in life expectancy AAA is becoming more prevalent in aging patients. Elective and emergency procedures in elderly patients with AAA are becoming more common, but the indications for aortic repair and outcomes in geriatric patients are debatable.

Coagulation Factor Activity and Hemostatic Markers of Endothelial Dysfunction in Patients with Peripheral Arterial Disease.

Purpose: We aimed to evaluate the impact of intrinsic coagulation factors and hemostatic markers of endothelial dysfunction on complications in patients with atherosclerotic peripheral arterial disease (PAD).

Materials And Methods: This prospective study enrolled 120 PAD patients at Fontaine stages 2b to 3 who underwent open surgical, endovascular, or conservative treatment. Coagulation factors (FVIII, FIX, and FXI) and endothelial hemostatic markers, including von Willebrand factor (vWF) activity and level, soluble endothelial protein C receptor, and plasminogen activator inhibitor-1 (PAI-1) levels, were assessed.

Autocrine-based selection of ligands for personalized CAR-T therapy of lymphoma.

We report the development of a novel platform to enhance the efficacy and safety of follicular lymphoma (FL) treatment. Since lymphoma is a clonal malignancy of a diversity system, every tumor has a different antibody on its cell surface. Combinatorial autocrine-based selection is used to rapidly identify specific ligands for these B cell receptors on the surface of FL tumor cells.
