One-step colorimetric immunosensing of foodborne bacteria using static magnet driven magnetophoretic separation and dual noble metal decorated magnetic nanobeads.

Background: Immunomagnetic separation is essential for screening pathogenic bacteria to prevent food poisoning. However, free immunomagnetic nanobeads (IMNBs) coexist with IMNB-bacteria conjugates (IBCs) after traditional immunomagnetic separation resulting in the infeasibility for IMNBs on IBCs to further act as signal label in bacterial detection. Although we have demonstrated that magnetophoretic separation at a high flowrate could separate IBCs from IMNBs, partial IMNBs were still found with IBCs due to chaotic flows and resulted in inevitable interferences.

Cascaded Gravity-Driven Microfluidic Chip with Tilt-Actuated Siphon Valves for Rapid Detection of Typhimurium.

In recent years, urgent food safety issues have heightened the demand for rapid detection technologies for foodborne pathogens, especially biosensors featuring simplicity, rapidity, and high sensitivity. Yet despite a booming surge in related published studies, commercializing these biosensors remains a constant challenge and persistent objective for researchers. In this study, a gravity-driven microfluidic chip with tilt-actuated siphon valves was developed, integrating silica magnetic beads based nucleic acid separation and recombinase-aided amplification (RAA) detection of Typhimurium by simple operations along with a portable biosensing device.

FlexibleSleepNet:A Model for Automatic Sleep Stage Classification Based on Multi-Channel Polysomnography.

In the task of automatic sleep stage classification, deep learning models often face the challenge of balancing temporal-spatial feature extraction with computational complexity. To address this issue, this study introduces FlexibleSleepNet, a lightweight convolutional neural network architecture designed around the Adaptive Feature Extraction (AFE) Module and Scale-Varying Compression (SVC) Module. Through multi-channel polysomnography data input and preprocessing, FlexibleSleepNet utilizes the AFE Module to capture intra-channel features and employs the SVC Module for channel feature compression and dimension expansion.

An empirical study of using radiology reports and images to improve intensive care unit mortality prediction.

Objectives: The predictive intensive care unit (ICU) scoring system is crucial for predicting patient outcomes, particularly mortality.

Materials And Methods: In this work, we build a deep learning-based survival prediction model that utilizes multimodality data for ICU mortality prediction.

JTCD attenuates HF by inhibiting activation of HSCs through PPARα-TFEB axis-mediated lipophagy.

Background: Hepatic fibrosis (HF) is an intermediate stage in the progression of chronic liver disease to cirrhosis and has been shown to be a reversible pathological process. Known evidence suggests that activation of hepatic stellate cells (HSCs) and degradation of their lipid droplets (LDs) play an indispensable role in the process of HF. Jiawei Taohe Chengqi Decoction (JTCD) can inhibit the activation of HSCs in the process of HF, but the exact mechanism remains to be elucidated.

REG3A secreted by peritumoral acinar cells enhances pancreatic ductal adenocarcinoma progression via activation of EGFR signaling.

Background: Regenerating family member 3A (REG3A) is involved in the development of multiple malignant tumors, including pancreatic ductal adenocarcinoma (PDAC). However, any role of REG3A in PDAC remains controversial due to its unclear tissue localization or direct receptors, and complex downstream signal transductions.

Methods: Morphological analysis and public multi-omics data retrieval were was utilized to elucidate the tissue localization of REG3A in PDAC.

Why is the rectal route for NSAIDS favorable for preventing post-ERCP pancreatitis?

Objective: Acute pancreatitis is a frequent, burdensome adverse event of endoscopic retrograde cholangiography (ERCP). Rectal nonsteroidal anti-inflammatory drugs (NSAIDs) have reduced post-ERCP pancreatitis (PEP) risk by about 50 % and show greater efficacy over parenteral or oral administration, although the mechanism for its superiority remains unclear. To probe this question, we investigated in a preclinical model, the pharmacokinetics in the blood, pancreas and other tissues of the NSAID diclofenac given via the rectal, intravenous, or intragastric routes.

Risk factors and machine learning prediction models for intrahepatic cholestasis of pregnancy.

Background: Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder that occurs in the second and third trimesters of pregnancy and is associated with a significant risk of fetal complications, including premature birth and fetal death. In clinical practice, the diagnosis of ICP is predominantly based on the presence of pruritus in pregnant women and elevated serum total bile acid. However, this approach may result in missed or delayed diagnoses.

Construction of a rodent neural network-skeletal muscle assembloid that simulate the postnatal development of spinal cord motor neuronal network.

Neuromuscular diseases usually manifest as abnormalities involving motor neurons, neuromuscular junctions, and skeletal muscle (SkM) in postnatal stage. Present in vitro models of neuromuscular interactions require a long time and lack neuroglia involvement. Our study aimed to construct rodent bioengineered spinal cord neural network-skeletal muscle (NN-SkM) assembloids to elucidate the interactions between spinal cord neural stem cells (SC-NSCs) and SkM cells and their biological effects on the development and maturation of postnatal spinal cord motor neural circuits.

Evaluating Meta-Learners to Analyze Treatment Heterogeneity in Survival Data: Application to Electronic Health Records of Pediatric Asthma Care in COVID-19 Pandemic.

An important aspect of precision medicine focuses on characterizing diverse responses to treatment due to unique patient characteristics, also known as heterogeneous treatment effects (HTE) or individualized treatment effects (ITE), and identifying beneficial subgroups with enhanced treatment effects. Estimating HTE with right-censored data in observational studies remains challenging. In this paper, we propose a pseudo-ITE-based framework for analyzing HTE in survival data, which includes a group of meta-learners for estimating HTE, a variable importance metric for identifying predictive variables to HTE, and a data-adaptive procedure to select subgroups with enhanced treatment effects.

tdCoxSNN: Time-dependent Cox survival neural network for continuous-time dynamic prediction.

The aim of dynamic prediction is to provide individualized risk predictions over time, which are updated as new data become available. In pursuit of constructing a dynamic prediction model for a progressive eye disorder, age-related macular degeneration (AMD), we propose a time-dependent Cox survival neural network (tdCoxSNN) to predict its progression using longitudinal fundus images. tdCoxSNN builds upon the time-dependent Cox model by utilizing a neural network to capture the nonlinear effect of time-dependent covariates on the survival outcome.

Isoferulic acid facilitates effective clearance of hypervirulent Klebsiella pneumoniae through targeting capsule.

Hypervirulent Klebsiella pneumoniae (hvKP) poses an alarming threat in clinical settings and global public health owing to its high pathogenicity, epidemic success and rapid development of drug resistance, especially the emergence of carbapenem-resistant lineages (CR-hvKP). With the decline of the "last resort" antibiotic class and the decreasing efficacy of first-line antibiotics, innovative alternative therapeutics are urgently needed. Capsule, an essential virulence determinant, is a major cause of the enhanced pathogenicity of hvKP and thus represents an attractive drug target to prevent the devastating clinical outcomes caused by hvKP infection.
