Article Synopsis
- The study investigates the differences in characteristics between culprit and non-culprit intracranial plaque using advanced 3D high-resolution vessel wall MRI in patients with cerebral ischemic symptoms.
- It focuses on patients with less than 50% stenosis in their intracranial atherosclerosis, analyzing features such as wall thickness, plaque burden, and hemorrhage within the plaque.
- The results show that culprit plaques had significantly greater plaque volume and enhancement ratios compared to non-culprit plaques, with these features being key determinants for diagnosing culprit plaques.
Background: Probiotics have been deemed multipotent and unprecedentedly applied in the health field recently. However, there are challenges in promoting credible and reliable resources while avoiding misinformation regarding probiotics for the public.
Methods: This study analysed 400 eligible probiotic-related videos selected from YouTube, and the three most popular video-sharing platforms (Bilibili, Weibo and TikTok) in China.
Adventitious root (AR) formation is of great significance for apple rootstock breeding. It is widely accepted that miR393 influences AR formation in many plant species; however, the molecular mechanism by which factors regulate AR formation remains insufficient. In this study, the evolutionary relationship of mdm-miR393 and candidate target genes MdTIR1/AFB was systematically identified, and the expression patterns were analysed.

Ying Yong Sheng Tai Xue Bao
January 2019
To explore the effects of different disturbance patterns on restoring the health of an infected stand, concentrated disturbance of not cutting trees before 10 years after infection, mode-rate disturbance of cutting infected pine trees, and strong distrubance of cutting infected pine trees, the neighboring trees and poorly growing pine trees were compared in a pure Pinus massomiana plantation infected by Bursaphelenchus xylophlius in Anji, Zhejiang, China. After 16 years, the importance values of P. massoniana in the three treatments were: concentrated disturbance > mode-rate disturbance > strong disturbance.

It is not clear so far how the composition of fatty acids, particular the immune-related, in marine crustacean and the subsequent energy supply in marine ecosystem are affected by OA. The brine shrimp Artemia sinica is an open and common feed that provide essential fatty acids for mariculture.

Results: There were no significant differences for the mean ADCs measured by 12 different-size ROIs for MFCP, or PDAC and NP ( = 0.858-1.
Article Synopsis
- The study aimed to evaluate and compare three different techniques for placing regions of interest (ROIs) to measure the apparent diffusion coefficient (ADC) in patients with pancreatic ductal adenocarcinoma (PDAC).
- Involving 21 PDAC patients and 18 healthy volunteers, researchers used diffusion-weighted imaging to assess ADCs, with measurements taken using whole-volume, single-slice, and small solid tumor samples.
- Results showed that ADCs from small solid samples provided the most accurate diagnosis of PDAC, significantly outperforming the other two methods based on their ROC curve areas, prompting a recommendation for using solid sample placements in clinical assessments.
Purpose: To assess the influence of region of interest (ROI) on tumor apparent diffusion coefficient (ADC) measurements and interobserver variability in pancreatic ductal adenocarcinoma (PDAC).
Materials And Methods: Twenty-two patients recruited with pathology-proven PDAC underwent diffusion-weighted imaging (DWI, 3.0T) prior to the surgical resection.
Background: To investigate the monoexponential and biexponential apparent diffusion parameters in different anatomical regions of the healthy pancreas using intravoxel incoherent motion (IVIM) diffusion weighted imaging (DWI).
Methods: Fifty-seven healthy volunteers (age, 45.0 ± 10.
Article Synopsis
- Diffusion weighted magnetic resonance imaging (DWI) typically uses single-shot echo-planar imaging (ss EPI), which helps minimize motion artifacts but limits resolution, especially in abdominal imaging.
- A new technique called reduced Field of View ss EPI (rFOV ss EPI) has shown to produce higher resolution images in carotid arteries and spinal cords but hasn't been applied to pancreas imaging until now.
- In a study comparing full FOV and rFOV DWI for pancreatic tumors and normal tissues, rFOV DWI demonstrated significantly better image quality and improved spatial resolution (from 3.0mm/pixel to 1.25mm/pixel) without substantial differences in ADC values.
Quantification of pancreatic exocrine function of chronic pancreatitis with secretin-enhanced MRCP.
World J Gastroenterol
November 2013
Aim: To obtain reference values for pancreatic flow output rate (PFR) and peak time (PT) in healthy volunteers and chronic pancreatitis (CP); to correlate quantification of secretin enhanced magnetic resonance cholangiopancreatography (SMRCP) of pancreatic fluid output following secretin with fecal elastase-1 (FE-1) tests.
Methods: The present study includes 53 subjects comprised of 17 healthy individuals and 36 patients with CP from April 2011 to January 2013. The 36 patients with CP were divided into three groups of mild CP (n = 14), moderate CP (n = 19) and advanced CP (n = 3) by M-ANNHEIM classification for CP.
Objective: To investigate the value of high b value diffusion-weighted (DW) imaging in differentiating between pancreatic carcinoma and mass-forming chronic pancreatitis (MFCP).
Methods: Fifty-one consecutive patients with pathology-proven pancreatic carcinoma (n = 37) or MFCP (n = 14) were evaluated with DW imaging (b value, 0 and 1000 s/mm(2)) at a 3-T MR system. Overall 20 healthy volunteers were evaluated as the control group.
[Study on infrared spectra characteristics of fault particles of the sulfide deposit].

Article Synopsis
- Previous research focused on the mineralization and movements of ore bodies during fault shifts, neglecting the particles formed from sulfide ore and surrounding rock.
- This study used FTIR spectroscopy and scanning electron microscopy to analyze fault particles from sulfide deposits, revealing the presence of newly identified minerals like hydrous sulfur calcium carbonate and changes in sulfur oxidation states.
- The findings are significant for the exploration and utilization of these ore deposits and highlight the effectiveness of infrared spectral analysis for studying minerals involved in fault movements.
