Strategies for detecting and identifying biological signals amidst the variation commonly found in RNA sequencing data.

BMC Genomics 2021 May 3;22(1):322. Epub 2021 May 3.

Molecular Research Center, Inc., Cincinnati, USA.

Background: RNA sequencing analysis focus on the detection of differential gene expression changes that meet a two-fold minimum change between groups. The variability present in RNA sequencing data may obscure the detection of valuable information when specific genes within certain samples display large expression variability. This paper develops methods that apply variance and dispersion estimates to intra-group data to identify genes with expression values that diverge from the group envelope. Read More

[Predictive value of combination of MRI tumor regression grade and apparent diffusion coefficient for pathological complete remission after neoadjuvant treatment of locally advanced rectal cancer].

Zhonghua Wei Chang Wai Ke Za Zhi 2021 Apr;24(4):359-365

Medical Imaging Center, the First Affiliate Hospital, Kunming Medical University, Kunming 650032, China.

Pelvic high-resolution magnetic resonance imaging (MRI) has now become a standard method for evaluating the efficacy of neoadjuvant treatment for locally advanced rectal cancer (LARC). However, this traditional morphological qualitative assessment method based on T2-weighted imaging (T2WI) is not effective in predicting pathological complete remission (pCR). The purpose of this study is to investigate whether combining the magnetic resonance tumor regression grade (mrTRG) with apparent diffusion coefficient (ADC) can improve diagnostic value for pCR after preoperative neoadjuvant chemoradiotherapy (nCRT) of LARC.

Application of conventional ultrasound coupled with virtual touch tissue imaging and quantification in the assessment of muscle strength.

Ann Palliat Med 2020 Sep;9(5):3402-3409

Department of Ultrasound, Chengdu First People's Hospital, Chengdu, China.
