Sensors, Vol. 19, Pages 4076: Super-Resolution Reconstruction of Cell Pseudo-Color Image Based on Raman Technology Sensors doi: 10.3390/s19194076 Authors: Yifan Yang Ming Zhu Yuqing Wang Hang Yang Yanfeng Wu Bei Li Raman spectroscopy visualization is a challenging task due to the interference of complex background noise and the number of selected measurement points. In this paper, a super-resolution image reconstruction algorithm for Raman spectroscopy is studied to convert raw Raman data into pseudo-color super-resolution imaging. Firstly, the Raman spectrum data of a single measurement point is measured multiple times to calculate the mean value to remove the random background noise, and innovatively introduce the Retinex algorithm and the median filtering algorithm which improve the signal-to-noise ratio. The novel method of using deep neural network performs a super-resolution reconstruction operation on the gray image. An adaptive guided filter that automatically adjusts the filter radius and penalty factor is proposed to highlight the contour of the cell, and the super-resolution reconstruction of the pseudo-color image of the Raman spectrum is realized. The average signal-to-noise ratio of the reconstructed pseudo-color image sub-band reaches 14.29 db, and the average value of information entropy reaches 4.30 db. The results show that the Raman-based cell pseudo-color image super-resolution reconstruction algorithm is an effective tool to effectively ...
ConclusionsPA activates PXR signalling and suppresses NF-κB signalling, consequently causing ameliorating inflammation. Results highlight the importance of PXR–NF-κB crosstalk in colitis and suggest a novel therapeutic reagent.Graphical abstract
ConclusionsThis study suggests that PLS exhibits anti-inflammatory action against intestinal damage by reducing inflammatory cell infiltration, oxidative stress, pro-inflammatory action of cytokines, and COX-2 expression in the inflamed colon. PLS shows therapeutic potential against inflammatory disorders like UC.Graphical abstract
ConclusionsThe findings indicate that combined traditional Thai herbal formulations can be used to successfully treat chronic eczema and could be considered as an alternative treatment for refractory chronic eczema.
ConclusionsFrailty assessment may be good value for money. However, limited availability of geriatric consultation services, may hinder implementation. Thus, the estimated benefits of frailty screening may not be achievable in practice.
We report the case of a 17-year-old patient with recurrent hemorrhagic pericardial effusion, who was diagnosed with primary pericardial fibrosarcoma. However, multiple radiological examinations, including CT and [18F] FDG/PET-CT, suggested the presence of fluid and no sign of tumor. Actually, when a patient presents with recurrent hemorrhagic pericardial effusions, pericardial tumors must be taken into account as part of the differential diagnosis.
We present two young patients (

We describe a contiguous gene deletion of the ATM locus in a multi-generation family of Italian descent with a strong family history of pancreatic cancer. A deletion of one copy of the entire ATM gene was identified by routine panel testing and further characterized by chromosomal microarray analysis. An 11q22.3 microdeletion of approximately 960kb was identified that is predicted to result in loss of 10 genes including ATM. The deletion was identified in two additional family members including a presymptomatic daughter and an affected sibling. A normal disomic complement of the 11q22.3 region was detected in a third famil...
Conclusions: The DC-TAV program is an ambitious, civilian-military, nationwide and long-term program, based on a harmonised standard of care and including multidimensional training. Further studies are required to assess its efficacy.

In elderly patients, this trial aimed to assess the impact of the addition of remifentanil during RSI on the occurrence of: tachycardia (primary outcome), hypertension (due to intubation) nor hypotension (rem...
