Robust joint modelling of longitudinal and survival data: Incorporating a time-varying degrees-of-freedom parameter.

Biom J 2021 Jul 28. Epub 2021 Jul 28.

Department of Statistics, Lund University, Lund, Sweden.

Monitoring of individual biomarkers has the potential of explaining the hazard of survival outcomes. In practice, these measurements are intermittently observed and are known to be subject to substantial measurement error. Joint modelling of longitudinal and survival data enables us to associate intermittently measured error-prone biomarkers with risks of survival outcomes and thus plays an important role in the analysis of medical data.

Epigenetic scarring of exhausted T cells hinders memory differentiation upon eliminating chronic antigenic stimulation.

Nat Immunol 2021 Aug 26;22(8):1008-1019. Epub 2021 Jul 26.

Department of Systems Pharmacology and Translational Therapeutics, University of Pennsylvania, Philadelphia, PA, USA.

Exhausted CD8 T cells (T) are a distinct state of T cell differentiation associated with failure to clear chronic viruses and cancer. Immunotherapies such as PD-1 blockade can reinvigorate T cells, but reinvigoration is not durable. A major unanswered question is whether T cells differentiate into functional durable memory T cells (T) upon antigen clearance. Read More

Quantification of tumor microenvironment acidity in glioblastoma using principal component analysis of dynamic susceptibility contrast enhanced MR imaging.

Sci Rep 2021 Jul 22;11(1):15011. Epub 2021 Jul 22.

Department of Radiology, Perelman School of Medicine, Hospital of University of Pennsylvania, University of Pennsylvania, Philadelphia, PA, USA.

Glioblastoma (GBM) has high metabolic demands, which can lead to acidification of the tumor microenvironment. We hypothesize that a machine learning model built on temporal principal component analysis (PCA) of dynamic susceptibility contrast-enhanced (DSC) perfusion MRI can be used to estimate tumor acidity in GBM, as estimated by pH-sensitive amine chemical exchange saturation transfer echo-planar imaging (CEST-EPI). We analyzed 78 MRI scans in 32 treatment naïve and post-treatment GBM patients. Read More

High-throughput human primary cell-based airway model for evaluating influenza, coronavirus, or other respiratory viruses in vitro.

Sci Rep 2021 07 22;11(1):14961. Epub 2021 Jul 22.

Bioengineering Division, Draper, Cambridge, MA, 02139, USA.

Influenza and other respiratory viruses present a significant threat to public health, national security, and the world economy, and can lead to the emergence of global pandemics such as from COVID-19. A barrier to the development of effective therapeutics is the absence of a robust and predictive preclinical model, with most studies relying on a combination of in vitro screening with immortalized cell lines and low-throughput animal models. Here, we integrate human primary airway epithelial cells into a custom-engineered 96-device platform (PREDICT96-ALI) in which tissues are cultured in an array of microchannel-based culture chambers at an air-liquid interface, in a configuration compatible with high resolution in-situ imaging and real-time sensing.

Community radio-based blended learning model: A promising learning model in remote area during pandemic era.

Heliyon 2021 Jul 9;7(7):e07511. Epub 2021 Jul 9.

Universitas Ahmad Dahlan, Jl. Kapas 9, Semaki, Umbulharjo, Yogyakarta, Indonesia.

The COVID-19 pandemic is a big challenge for education worldwide because education has to be done virtually to stop the spread of the COVID-19. The problem is that there are students who live in areas far from cities, while learning in an interconnected world should be done virtually. Diverse geographical conditions in Indonesia consisting of mountains, lowlands, highlands, and valleys and some areas that are far away from cities make students difficult to connect to the internet and thus, virtual teaching is challenging.

Rat model of smoke inhalation-induced acute lung injury.

BMJ Open Respir Res 2021 Jul;8(1)

Surgery, University of Nebraska Medical Center, Omaha, Nebraska, USA

Background: Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is a lethal disease with limited therapeutic options and an unacceptably high mortality rate. Understanding the complex pathophysiological processes involved in the development of ALI/ARDS is critical for developing novel therapeutic strategies. Smoke inhalation (SI) injury is the leading cause of morbidity and mortality in patients with burn-associated ALI/ARDS; however, to our knowledge few reliable, reproducible models are available for pure SI animal model to investigate therapeutic options for ALI/ARDS without the confounding variables introduced by cutaneous burn or other pathology.

Psychosocial Work Environment and Teachers' Psychological Well-Being: The Moderating Role of Job Control and Social Support.

Int J Environ Res Public Health 2021 Jul 8;18(14). Epub 2021 Jul 8.

Faculty of Business, Economics and Social Development, Universiti Malaysia Terengganu, Kuala Nerus 21030, Terengganu, Malaysia.

Nowadays, the issue of teachers' psychological well-being causes serious concern, especially in Malaysia. Many studies related to psychological well-being have focused on students rather than on the health and well-being of teachers. Thus, the current study investigated the determinants of psychological well-being (depression, anxiety and stress) from the psychosocial work environment (job control, job demands and social support), and examined the moderating role of job control and social support in the relationship between job demands and psychological well-being among teachers.

Contribution of Heparan Sulphate Binding in CCL21-Mediated Migration of Breast Cancer Cells.

Cancers (Basel) 2021 Jul 10;13(14). Epub 2021 Jul 10.

Theme-Immunity and Inflammation, Faculty of Medical Sciences, Translational and Clinical Research Institute, Newcastle University, 3rd Floor Leech Building, Newcastle upon Tyne NE2 4HH, UK.

Chemokine receptor CCR7 is implicated in the metastasis of breast cancer to the lymph nodes. Chemokine function is dependent upon their binding to both cell-surface heparan sulphate (HS) and to their specific receptors; thus, the role of HS in CCR7-mediated lymph node metastasis was investigated by creating a non-HS binding chemokine CCL21 (mut-CCL21). Mut-CCL21 (Δ103-134) induced leukocyte chemotaxis in diffusion gradients but did not stimulate trans-endothelial migration of PBMCs ( < 0. Read More

Qualification of Soybean Responses to Flooding Stress Using UAV-Based Imagery and Deep Learning.

Plant Phenomics 2021 28;2021:9892570. Epub 2021 Jun 28.

Division of Plant Sciences, University of Missouri, Columbia, MO 65211, USA.

Soybean is sensitive to flooding stress that may result in poor seed quality and significant yield reduction. Soybean production under flooding could be sustained by developing flood-tolerant cultivars through breeding programs. Conventionally, soybean tolerance to flooding in field conditions is evaluated by visually rating the shoot injury/damage due to flooding stress, which is labor-intensive and subjective to human error.
