Microfluidics sorting enables the isolation of an intact cellular pair complex of CD8 < sup > + < /sup > T cells and antigen-presenting cells in a cognate antigen recognition-dependent manner
In this study , we successfully isolated intact antigen-specific cellular complexes of CD8+ T/APC by utilizing a microfluidics cell sorter. Using ovalbumin (OVA) model antigen and OT-I-derived OVA-specific CD8+ T cells, we analyzed the formation of antigen-specific and antigen-non-specific T/APC cellular complexes and revealed that the antigen-specific T/APC cellular complex was highly stable than the non-specific one, and that the intact antigen-specific T/APC complex can be retrieved as well as enriched using a microfluidics sorter, but not a conventional cell sorter. The single T/APC cellular complex obtained can be fur...

< i > In silico < /i > analysis of deleterious SNPs of human < i > MTUS1 < /i > gene and their impacts on subsequent protein structure and function
by Liza Teresa Rozario, Tanima Sharker, Tasnin Akter Nila The mitochondrial tumor suppressor 1 (MTUS1) gene acts as a crucial tumor suppressor by inhibiting growth and proliferation of eukaryotic cells including tumor cell lines. Down regulation ofMTUS1 gene has been implicated in a wide range of cancers as well as various human diseases. Alteration through nsSNPs can potentially damage the structure and/or function of the protein. As characterization of functional SNPs in such disease linked genes is a major challenge, it is feasible to analyze putative functional SNPs prior to performing larger population studies. Hence...

Spatial inhibition of return is impaired in mild cognitive impairment and mild Alzheimer ’s disease
by Xiong Jiang, James H. Howard Jr., G.

Here with a group of older adults (n = 56, 58–80 (67.9±5.2) year old, 31 females, 18.7±3.6 years of education ), we provide evidence supporting the notion that spatial IOR is mildly impaired in individuals with mild cognitive impairment (MCI) or mild Alzheimer’s disease (AD), and the impairment is detectable using a double cue paradigm.

Medication-related hospital readmissions within 30 days of discharge —A retrospective study of risk factors in older adults
ConclusionPossibly medication-related readmissions within 30 days of discharge, in patients 65 years and older, are common. The odds of such readmissions increase in comorbid, highly medicated patients living in their own home, alone, and if having medication dosages adjusted at initial discharge. These results indicate that care planning before discharge and the provision of help with, for example, managing medications after discharge, are factors especially important if aiming to reduce the amount of medication-related readmissions among this population. Further research is needed to confirm this hypothesis. (Source: PLoS One)

Age-structured Jolly-Seber model expands inference and improves parameter estimation from capture-recapture data
We present a novel age-structured Jolly-Sebe r model that incorporates age and capture-recapture data to provide comprehensive information on population dynamics, including abundance, age-dependent survival, recruitment, age structure, and population growth rates. We applied our model to a multi-year capture-recapture study of polar bears (Ursus maritimus) in western Hudson Bay, Canada (2012 –2018), where management and conservation require a detailed understanding of how polar bears respond to climate change and other factors. In simulation studies, the age-structured Jolly-Seber model improved precision of survival...

The impact of organizational culture on professional fulfillment and burnout in an academic department of medicine
by Karen E. A. Burns, Reena Pattani, Edmund Lorens, Sharon E. Straus, Gillian A. Hawker Physician wellness is vital to career satisfaction, provision of high quality patient care, and the successful education of the next generation of physicians. Despite this, the number of physicians experience symptoms of burnout is rising. To assess the impact of organizational culture on physicia ns’ professional fulfillment and burnout, we surveyed full-time Department of Medicine members at the University of Toronto. A cross-sectional survey assessed: physician factors (age, gender, minority status, disability, desire to reduc...

Enlightenment on oscillatory properties of 23 class B notifiable infectious diseases in the mainland of China from 2004 to 2020
In this study, we collec ted time-series data for 23 class B notifiable infectious diseases from 2004 to 2020 using public datasets from the National Health Commission of China. Oscillatory properties were explored using power spectrum analysis. We found that the 23 class B diseases from the dataset have obvious oscillatory patterns (seasonal or sporadic), which could be divided into three categories according to their oscillatory power in different frequencies each year. These diseases were found to have different preferred outbreak months and infection selectivity. Diseases that break out in autumn and winter are mo re s...
