Assessment of the relative cardiotoxicity and behavioral effects of butylated hydroxytoluene and its metabolites in developing zebrafish (Danio rerio).

Butylated hydroxytoluene (BHT) and its transformation products are ubiquitously detected in aquatic environments. Despite studies reporting on the adverse effects of BHT exposure in early-staged zebrafish, the comparative toxicity of its metabolites is not known. To address this, zebrafish embryos were exposed continuously to 0.

Polystyrene nanoplastics alter intestinal toxicity of 2,4-DTBP in a sex-dependent manner in zebrafish (Danio rerio).

Nanoplastics (NPs) and 2,4-di-tert-butylphenol (2,4-DTBP) are ubiquitous emerging environmental contaminants detected in aquatic environment. While the intestinal toxicity of 2,4-DTBP alone has been studied, its combined effects with NPs remain unclear. Herein, adult zebrafish were exposed to 80 nm polystyrene nanoplastics (PS-NPs) or/ and 2,4-DTBP for 28 days.

Evaluation of residual plastic film pollution in pre-sowing cotton field using UAV imaging and semantic segmentation.

To accurately evaluate residual plastic film pollution in pre-sowing cotton fields, a method based on modified U-Net model was proposed in this research. Images of pre-sowing cotton fields were collected using UAV imaging from different heights under different weather conditions. Residual films were manually labelled, and the degree of residual film pollution was defined based on the residual film coverage rate.

Volumetric reduction of cerebellar lobules associated with memory decline across the adult lifespan.

Background: The human cerebellum plays an essential role in motor control, is involved in cognitive function and helps to regulate emotional responses. However, little is known about the relationship between cerebellar lobules and age-related memory decline. We aimed to investigate volume alterations in cerebellar lobules at different ages and assess their correlations with reduced memory recall abilities.

[Development of Health Intelligent Management Cloud Platform on Maternal and Infant Monitor].

Objective: Using the wireless mobile communication technology and Internet technology, cloud platform to build maternal and infant health intelligent management.

Methods: Using the J2EE technology based on B/S three-tier to build health intelligent management cloud platform. Vital signs parameters (such as blood pressure, blood oxygen saturation, heart rate, breathing, pulse, temperature, instantaneous heart rate of pregnant women, etc) achieved the real-time detection and wireless remote transmission.

[Development of a portable dynamic state ECG based on DSP].

The Portable dynamic state electrocardiogram collecting system is introduced by using TMS302VC5402, TLC320AD50C, liquid crystal display model, and so on. This dissertation describes the work principle of the system and uses the united algorithm based on wavelet to identify and locate the ECG characteristic waves. This system has as follows of advantages: big memory, low noise,high common mode rejection ratio, the low power consume,the long record time etc.
