Published: December 2008

The authors report the case of a baby boy born at a gestational age of 32 weeks who experienced a life-threatening event triggered by vagal overactivity, associated with a transient phase of inverse coupling with a 1:1 phase ratio between ECG and respiration, resulting in respiratory arrest. This case report highlights the vital importance of coupling between cardiac and respiratory oscillators, especially in premature infants or neonates.

Vertical flow immunoassay for multiplex mycotoxins based on photonic nitrocellulose and SERS nanotags.

Food Chem X

January 2025

State Key Laboratory of Digital Medical Engineering, School of Biological Science and Medical Engineering, Southeast University, Nanjing 210096, China.

Here, we report a SERS based VFA using PNC as a sensing substrate for highly sensitive multiplex mycotoxins detection. The PNC was fabricated by filtration-based self-assembled monodisperse SiO NPs on a filter membrane as a template, and the obtained PNC had an ordered complementary inverse opal structure. In parallel, three kinds of Raman dyes encoding Au@Ag, Au@Ag and Au@Ag SERS nanotags were synthesized for the detection of OTA, AFB1 and ZON.

Background And Aims: Alcohol Use Disorder (AUD) is a psychiatric disorder characterized notably by gut microbial dysbiosis and insufficient dietary fiber intake. This study aims to investigate the effect of dietary fiber placebo-controlled intervention in patients suffering from AUD during a three-week period of alcohol withdrawal, in order to discover microbial-derived metabolites that could be involved in metabolic and behavioral status.

Methods: A randomized, double-blind, placebo-controlled study was performed with 50 AUD patients supplemented with inulin (prebiotic dietary fiber) or maltodextrin (placebo) during 17 days.

Multi-metal mixture exposure and cognitive function in urban older adults: The mediation effects of thyroid hormones.

Ecotoxicol Environ Saf

Department of Sanitary Chemistry, School of Public Health, Guangxi Medical University, Nanning 530021, China; Guangxi Key Laboratory of Environmental Exposomics and Entire Lifecycle Health, Guilin Medical University, China. Electronic address:

The existing studies on the association between multi-metal mixture exposure and cognitive function in the older adults are limited and controversial, with no studies considering the mediating effect of thyroid hormones on the connection between them. This study of 441 urban older adults assessed 21 urinary metal levels and cognitive function using the Mini-Mental State Examination (MMSE). Urinary metal levels were measured via inductively coupled plasma mass spectrometry (ICP-MS), and thyroid hormones levels were obtained from medical records.

Photoassisted lithium-sulfur (Li-S) batteries offer a promising approach to enhance the catalytic transformation kinetics of polysulfide. However, the development is greatly hindered by inadequate photo absorption and severe photoexcited carriers recombination. Herein, a photonic crystal sulfide heterojunction structure is designed as a bifunctional electrode scaffold for photoassisted Li-S batteries.

Steam Generator Maintenance Robot Design and Obstacle Avoidance Path Planning.

Sensors (Basel)

January 2025

College of Resource Environmental and Safety Engineering, University of South China, Hengyang 421001, China.

To solve the issue of inconvenient and dangerous manual operation during the installation and removal of the main pipe plugging plate in the steam generator in nuclear power plants, a ten-degree-of-freedom plugging robot was designed in the present study that includes a collaborative robotic arm coupled with a servo electric cylinder. By establishing a joint coordinate system for the robot model, a D-H parameter model for the plate plugging robot was established, and the forward and inverse kinematics were solved. The volume level approximate convex decomposition algorithm was used to fit the steam generator model with a convex packet, and an experimental simulation platform was constructed.
