Transcranial Direct Current Stimulation (tDCS) over the Intraparietal Sulcus Does Not Influence Working Memory Performance.

Psychol Belg 2021 9;61(1):200-211. Epub 2021 Jul 9.

Psychology & Neuroscience of Cognition Research Unit, University of Liège, Belgium.

Mixed results of the impact of transcranial direct current stimulation (tDCS) on working memory have been reported. Contrarily to previous studies who focused mainly on stimulating the dorsolateral prefrontal cortex, we modulated the left intraparietal sulcus (IPS) area which is considered to support attentional control aspects of working memory. Using a within-participant experimental design, participants completed three different conditions: anodal stimulation of the IPS, cathodal stimulation of the IPS, and sham stimulation of the IPS.

Evidence That Tumor Microenvironment Initiates Epithelial-To-Mesenchymal Transition and Calebin A can Suppress it in Colorectal Cancer Cells.

Front Pharmacol 2021 2;12:699842. Epub 2021 Jul 2.

Musculoskeletal Research Group and Tumor Biology, Chair of Vegetative Anatomy, Faculty of Medicine, Institute of Anatomy, Ludwig-Maximilian-University Munich, Munich, Germany.

Tumor microenvironment (TME) has a pivotal impact on tumor progression, and epithelial-mesenchymal transition (EMT) is an extremely crucial initial event in the metastatic process in colorectal cancer (CRC) that is not yet fully understood. Calebin A (an ingredient in ) has been shown to repress CRC tumor growth. However, whether Calebin A is able to abrogate TME-induced EMT in CRC was investigated based on the underlying pathways.

Adherence to the World Cancer Research Fund/American Institute for Cancer Research cancer prevention recommendations and colorectal cancer survival.

Cancer Epidemiol Biomarkers Prev 2021 Jul 16. Epub 2021 Jul 16.

Department of Nutrition, Harvard T.H. Chan School of Public Health

Background: Cancer patients are recommended to follow cancer prevention guidelines due to inadequate evidence for specific recommendations for cancer survivors.

Cancer Epidemiol Biomarkers Prev 2021 Jul 16. Epub 2021 Jul 16.

Pathology, GROW School of Oncology and Developmental Biology, Maastricht University Medical Center

Background: Scoring of immunohistochemical (IHC) staining is often done by non-pathologists, especially in large-scale Tissue MicroArray (TMA)-based studies. Studies on the validity of scoring results from non-pathologists are very limited. Therefore, our main aim was to assess inter-observer agreement between trained non-pathologists and an experienced histopathologist for three IHC markers with different subcellular localization (nucleus/membrane/cytoplasm).

Noninvasive quantitative assessment of collagen degradation in parchments by polarization-resolved SHG microscopy.

Sci Adv 2021 Jul 16;7(29). Epub 2021 Jul 16.

Laboratoire d'Optique et Biosciences, Ecole polytechnique, CNRS, INSERM, Institut Polytechnique de Paris, Palaiseau, France.

Nondestructive and noninvasive investigation techniques are highly sought-after to establish the degradation state of historical parchments, which is up to now assessed by thermal techniques that are invasive and destructive. We show that advanced nonlinear optical (NLO) microscopy enables quantitative in situ mapping of parchment degradation at the micrometer scale. We introduce two parameters that are sensitive to different degradation stages: the ratio of two-photon excited fluorescence to second harmonic generation (SHG) signals probes severe degradation, while the anisotropy parameter extracted from polarization-resolved SHG measurements is sensitive to early degradation.

Evaluation of Protein Purification Techniques and Effects of Storage Duration on LC-MS/MS Analysis of Archived FFPE Human CRC Tissues.

Pathol Oncol Res 2021 3;27:622855. Epub 2021 May 3.

South African Medical Research Council Bioinformatics Unit, South African National Bioinformatics Institute, University of the Western Cape, Bellville, South Africa.

To elucidate cancer pathogenesis and its mechanisms at the molecular level, the collecting and characterization of large individual patient tissue cohorts are required. Since most pathology institutes routinely preserve biopsy tissues by standardized methods of formalin fixation and paraffin embedment, these archived FFPE tissues are important collections of pathology material that include patient metadata, such as medical history and treatments. FFPE blocks can be stored under ambient conditions for decades, while retaining cellular morphology, due to modifications induced by formalin. Read More

Impact of assumptions on future costs, disutility and mortality in cost-effectiveness analysis; a model exploration.

PLoS One 2021 12;16(7):e0253893. Epub 2021 Jul 12.

Department of Public Health, Erasmus MC University Medical Center Rotterdam, Rotterdam, The Netherlands.

Introduction: In cost-effectiveness analyses, the future costs, disutility and mortality from alternative causes of morbidity are often not completely taken into account.

Extracellular Flux Analysis to Investigate the Impact of NF-κB on Mitochondrial Respiration in Colorectal Carcinoma (CRC).

Methods Mol Biol 2021 ;2366:293-303

Centre for Molecular Immunology and Inflammation, Department of Immunology and Inflammation, Imperial College London, London, UK.

The reprogramming of cell metabolism is a hallmark of cancer. NF-κB transcription factors coordinate the host defense responses to stress, injury, and infection. They also play a central role in oncogenesis, at least in part by regulating cell metabolism and the adaptation to energy stress conditions in various types of cancer, such as colorectal carcinoma (CRC).

Path Analysis of the Impact of Obesity on Postoperative Outcomes in Colorectal Cancer Patients: A Population-Based Study.

J Clin Med 2021 Jun 29;10(13). Epub 2021 Jun 29.

Division of Colon & Rectal Surgery, Department of Surgery, E-DA Hospital, Kaohsiung 82445, Taiwan.

Insulin-Like Growth Factor 2 mRNA-Binding Protein 1 (IGF2BP1) Is a Prognostic Biomarker and Associated with Chemotherapy Responsiveness in Colorectal Cancer.

Int J Mol Sci 2021 Jun 28;22(13). Epub 2021 Jun 28.

Faculty of Medicine, School of Medicine, National Yang Ming Chiao Tung University, Taipei 112, Taiwan.

Insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) is an RNA-binding protein and serves as a post-transcriptional fine-tuner regulating the expression of mRNA targets.

Analyzing the Opportunities to Target DNA Double-Strand Breaks Repair and Replicative Stress Responses to Improve Therapeutic Index of Colorectal Cancer.

Cancers (Basel) 2021 Jun 23;13(13). Epub 2021 Jun 23.

Laboratory of Genetic Toxicology, Federal University of Health Sciences of Porto Alegre, Avenida Sarmento Leite, 245, Porto Alegre 90050-170, Brazil.

Despite the ample improvements of CRC molecular landscape, the therapeutic options still rely on conventional chemotherapy-based regimens for early disease, and few targeted agents are recommended for clinical use in the metastatic setting. Moreover, the impact of cytotoxic, targeted agents, and immunotherapy combinations in the metastatic scenario is not fully satisfactory, especially the outcomes for patients who develop resistance to these treatments need to be improved. Here, we examine the opportunity to consider therapeutic agents targeting DNA repair and DNA replication stress response as strategies to exploit genetic or functional defects in the DNA damage response (DDR) pathways through synthetic lethal mechanisms, still not explored in CRC.
