Recanalization and reperfusion in clinically-relevant porcine model of stroke.

Introduction: Stroke is a leading cause of death and long-term disability. Pigs have been considered an ideal large animal model in biomedicine; however, the complex vascular anatomy has posed challenges for stroke research. Nonetheless, we have previously overcome these limitations and demonstrated the feasibility of endovascularly inducing stroke in pigs.

The evaluation of the flow re-direction endoluminal device (FRED) for the treatment of selected intracranial aneurysms: a Polish multicenter study.

This Polish multicenter study aims to evaluate the effectiveness and safety of the Flow Direction Endoluminal Device (FRED) in treating selected unruptured intracranial aneurysms. The FRED Poland Study was an observational, multicenter, prospective study conducted in 8 Polish investigational sites. Imaging results were independently assessed by a Corelab and adverse events were adjudicated by a Clinical Events Committee (CEC).

Genetic basis of sow hyperprolificacy and litter size optimization based on a genome-wide association study.

Over the last few decades, there has been a constant increase in sow litter size, the consequences of which include parturition duration extension, an increase in the percentage of stillborn and hypoxic piglets, and increased variation in piglet birth weight, which reduces their vitality. As such, it seems clear that further increasing sow fertility will generate difficulties and costs in rearing numerous litters with low birth weights. Therefore, the current study aimed to analyze the genetic background of sow hyperprolifcacy using a genome-wide association study (GWAS).

Identification of SNP markers for canine mammary gland tumours in females based on a genome-wide association study - preliminary results.

Introduction: The development of genetic research over recent decades has enabled the discovery of new genetic markers, such as single nucleotide polymorphisms (SNPs). This, as well as the full sequencing of the dog genome, has enabled genome-wide association studies (GWAS) to be used in the search for genetic causes of canine mammary tumours (CMTs).

Material And Methods: Genotypic data containing 175,000 SNPs, which had been obtained using the Illumina CanineHD BeadChip microarray technique, were available for analysis in this study.

General vs Local Anesthesia for Percutaneous Endoscopic Lumbar Discectomy (PELD): A Systematic Review and Meta-Analysis.

Study Design: Systematic review.

Objectives: It remains unknown whether general anesthesia (GA) or local ± epidural anesthesia (LA) results in superior outcomes with percutaneous endoscopic lumbar discectomy (PELD). The present study sought to examine the impact of anesthesia type on patient-reported outcomes (PROs) and complications with PELD.

An effect of large-scale deletions and duplications on transcript expression.

Since copy number variants (CNVs) have been recognized as an important source of genetic and transcriptomic variation, we aimed to characterize the impact of CNVs located within coding, intergenic, upstream, and downstream gene regions on the expression of transcripts. Regions in which deletions occurred most often were introns, while duplications in coding regions. The transcript expression was lower for deleted coding (P = 0.

Clipping of a ruptured middle cerebral artery aneurysm in a patient with coronavirus disease 2019 (COVID-19): A case report.

Aim Of The Study: The aim of this study is to present our suggestions for organization, personal protective equipment (PPE) use, work flow of the operating theater, and the treatment of patients with COVID-19 and co-existing neurological disease.

Materials And Methods: We present the case of a 70-year-old male who was transferred to our Department because of subarachnoid hemorrhage with ruptured right middle cerebral artery aneurysm and SARS CoV-2 infection. The emergency clipping of the aneurysm and hematoma evacuation was performed.

Transformation of a large multi-speciality hospital into a dedicated COVID-19 centre during the coronavirus pandemic.

Introduction: The article describes the process of converting a large multi-specialized hospital into one dedicated to COVID-19 patients, and present established standards of work organization in all the wards and training system of the medical and supporting staff. The several weeks pandemic of the COVID-19 disease has forced the healthcare systems of numerous countries to adjust their resources to the care of the growing number of COVID-19 patients. Managers were presented with the challenge of protecting the healthcare workers from transmission of the disease within medical institutions, and issues concerning the physical and psychological depletion of personnel.

Mesenchymal stem cells injected into carotid artery to target focal brain injury home to perivascular space.

: The groundbreaking discovery of mesenchymal stem cells (MSCs) with their multifaceted benefits led to their widespread application in experimental medicine, including neurology. Efficient delivery of MSCs to damaged regions of the central nervous system may be a critical factor in determining outcome. Integrin VLA-4 (α4β1) coded by ITGA4 and ITGB1 genes is an adhesion molecule expressed by leukocytes, which is responsible for initiation of their diapedesis through cell docking to the inflamed vessel wall expressing VCAM1 receptor.

Clinical characteristics and short-term outcomes of patients with coronavirus disease 2019: a retrospective single-center experience of a designated hospital in Poland.

Introduction: Since the first reported case of coronavirus disease 2019 (COVID‑19) in Poland, the worldwide pandemic has spread throughout the country, leading to many hospital admissions. There has been an urgent need to determine clinical characteristics of Polish patients with laboratory‑confirmed severe acute respiratory syndrome coronavirus 2 (SARS‑CoV 2) infection in the clinical setting.

Objectives: The aim of this retrospective study was to outline characteristics and short‑ term outcomes of SARS‑CoV‑2-positive patients.

sPECAM-1 and sVCAM-1: Role in Pathogenesis and Diagnosis of Chronic Hepatitis C and Association with Response to Antiviral Therapy.

Aim: To analyze the relationship between pretreatment clinical or histological features and the levels of soluble platelet-endothelial cell adhesion molecule-1 (sPECAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1), to determine their serum concentration in responders and nonresponders, to evaluate the behavior under antiviral therapy, to explain their relationship in response to therapy and to assess the association between these two molecules in chronic hepatitis C (CHC).

Methods: The study analyzed 65 CHC patients, including 50 patients (Group 1) with marked fibrosis treated with peginterferon plus ribavirin, 15 patients without fibrosis (Group 2) and 13 healthy volunteers (the control group, Group 3). sPECAM-1 and sVCAM-1 levels were assessed by an immunoenzymatic method (ELISA) before and after therapy.
