The assessment of cognitive and behavioural disturbances in vascular cognitive impairment (VCI) - recommendations of an expert working group.

Neurol Neurochir Pol 2021 Jun 7. Epub 2021 Jun 7.

Faculty of Medicine, University of Belgrade, Belgrade, Serbia.

With newer research-based classification systems, the term Vascular Cognitive Impairment (VCI) is now preferred to vascular dementia. VCI is an umbrella term that includes all forms of cognitive deficits ranging from mild cognitive impairment of vascular origin (VaMCI) to vascular dementia (VaD). The new VCI construct takes into account the fact that in addition to single strategic infarcts, multiple infarcts, and leukoaraiosis, there are other mechanisms of cerebrovascular disease such as chronic hypoperfusion that might account for the pattern of cognitive deficits associated with vascular dementia.

Ononin induces cell apoptosis and reduces inflammation in rheumatoid arthritis fibroblast-like synoviocytes by alleviating MAPK and NF-κB signaling pathways.

Acta Biochim Pol 2021 Jun;68(2):239-245

Department of Joint Surgery, The Fifth Affiliated Hospital of Southern Medical University, Guangzhou, Guangdong Province, 510900, China.

As a kind of chronic inflammatory diseases, Rheumatoid arthritis (RA) has a low cure rate and easy recurrence. It has widely reported that abnormal activation of mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling pathways are associated with the development of RA inflammation. Blocking the inflammatory signaling pathways of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) can delay the development of RA. Read More

The Ribosomal Gene Loci-The Power behind the Throne.

Genes (Basel) 2021 May 18;12(5). Epub 2021 May 18.

ACRF Department of Cancer Biology and Therapeutics, John Curtin School of Medical Research, Australian National University, Acton 2601, Australia.

Nucleoli form around actively transcribed ribosomal RNA (rRNA) genes (rDNA), and the morphology and location of nucleolus-associated genomic domains (NADs) are linked to the RNA Polymerase I (Pol I) transcription status. The number of rDNA repeats (and the proportion of actively transcribed rRNA genes) is variable between cell types, individuals and disease state. Substantial changes in nucleolar morphology and size accompanied by concomitant changes in the Pol I transcription rate have long been documented during normal cell cycle progression, development and malignant transformation.

ARS2/SRRT: at the nexus of RNA polymerase II transcription, transcript maturation and quality control.

Biochem Soc Trans 2021 Jun 1. Epub 2021 Jun 1.

Aarhus University, Aarhus, Denmark.

ARS2/SRRT is an essential eukaryotic protein that has emerged as a critical factor in the sorting of functional from non-functional RNA polymerase II (Pol II) transcripts. Through its interaction with the Cap Binding Complex (CBC), it associates with the cap of newly made RNAs and acts as a hub for competitive exchanges of protein factors that ultimately determine the fate of the associated RNA. The central position of the protein within the nuclear gene expression machinery likely explains why its depletion causes a broad range of phenotypes, yet an exact function of the protein remains elusive.

Assistant professor of Pathology, Faculty of Medicine, Minia University, Minia, Egypt.

Colorectal cancer (CRC) is the third most common cancer worldwide and is associated with a high level of mortality and morbidity. In this study we evaluate expression of p-p38 and p-MSK1 in CRC and determine whether there is an association between expression of these markers and any clinicopathologic parameters that could be of prognostic value. Expression of p-p38, p-MSK1 and ki-67 were examined by immunohistochemistry in 135 archival CRC cases and the findings were correlated with the patient clinicopathological data. Read More

Battery for deep brain stimulation depletion in Parkinson's Disease and dystonia patients - a systematic review.

Neurol Neurochir Pol 2021 May 31. Epub 2021 May 31.

Neurology&Stroke Dpt., St. Adalbert Hospital, Gdańsk, Poland.

Introduction: Deep brain stimulation (DBS) therapy for Parkinson's Disease (PD) and dystonia is associated with the possibility of both minor and major complications. One possible side effect is the depletion of implantable pulse generator (IPG) battery and the associated sudden recurrence of PD or dystonia symptoms, which can be potentially life-threatening. Delayed or postponed outpatient visits due to COVID -19 may be a risk factor of battery end-of-life consequences. Read More

Regulation of RNA Polymerase II Transcription Initiation and Elongation by Transcription Factor TFII-I.

Front Mol Biosci 2021 13;8:681550. Epub 2021 May 13.

Department of Biochemistry and Molecular Biology, College of Medicine, UF Health Cancer Center, Genetics Institute, Powell Gene Therapy Center, University of Florida, Gainesville, FL, United States.

Transcription by RNA polymerase II (Pol II) is regulated by different processes, including alterations in chromatin structure, interactions between distal regulatory elements and promoters, formation of transcription domains enriched for Pol II and co-regulators, and mechanisms involved in the initiation, elongation, and termination steps of transcription. Transcription factor TFII-I, originally identified as an initiator (INR)-binding protein, contains multiple protein-protein interaction domains and plays diverse roles in the regulation of transcription. Genome-wide analysis revealed that TFII-I associates with expressed as well as repressed genes. Read More

Cardiovascular dysautonomia and cognition in Parkinson's Disease - a possible relationship.

Neurol Neurochir Pol 2021 May 26. Epub 2021 May 26.

Department of Neurological Psychiatric Nursing, Medical University of Gdansk, Poland, ul. M. Skłodowskiej-Curie 3a, 80-210 Gdańsk, Poland.

Dementia in advanced Parkinson's Disease (PD) is a fatal milestone resulting in reduced life expectancy and nursing home placement. Cognitive impairment and cardiovascular dysautonomia are common and debilitating non-motor symptoms that frequently coexist in PD since the early stages and progress in subsequent years. In particular, blood pressure (BP) abnormalities, including orthostatic hypotension (OH), supine hypertension (SH) and the loss of nocturnal BP fall (non-dipping) in PD have been associated with cognitive deterioration.
