Bisphenol and analogues in indoor dust from E-waste recycling sites, neighboring residential homes, and urban residential homes: Implications for human exposure.

The compound 4-hydroxyphenyl 4-isoprooxyphenylsulfone (BPSIP) has recently emerged as a novel alternative to bisphenol A (BPA) and has been found in various paper products. However, there is limited information available regarding the identification of BPSIP as a novel contaminant in the e-waste dismantling area. In our research, we conducted a comprehensive analysis of 16 bisphenol analogues (BPs), including BPSIP, within indoor dust samples obtained from a representative e-waste recycling facility, neighboring rural communities, and control urban communities.

Distribution characteristics of photoinitiators and their flux estimation from the Pearl River Delta to the coastal waters of the South China Sea.

Photoinitiators (PIs) are widely used in industrial polymerization processes. It has been reported that PIs are ubiquitous in indoor environments and that humans are exposed to PIs, but the occurrence of PIs in natural environments are rarely known. In the present study, 25 PIs, including 9 benzophenones (BZPs), 8 amine co-initiators (ACIs), 4 thioxanthones (TXs) and 4 phosphine oxides (POs), were analyzed in water and sediment samples collected from eight riverine outlets of the Pearl River Delta (PRD).

Broadening the lens on bisphenols in coastal waters: Occurrence, partitioning, and input fluxes of multiple novel bisphenol S derivatives along with BPA and BPA analogues in the Pearl River Delta, China.

Bisphenol S derivatives (BDs) are being widely used as novel substitutes for BPA and BPA analogues (BPAs), causing pollution in various environmental compartments. However, the occurrence and fate of BDs in coastal waters are currently unknown. To broaden the lens on bisphenols in coastal waters, this study measured a broad suite of 23 bisphenols, including 12 BDs along with BPA and 10 BPAs, in water, suspended particulate matter (SPM), and sediment from eight major outlets of the Pearl River Delta, China (PRD).

Comprehensive Identification of Liquid Crystal Monomers-Biphenyls, Cyanobiphenyls, Fluorinated Biphenyls, and their Analogues-in Waste LCD Panels and the First Estimate of their Global Release into the Environment.

Our previous study demonstrated massive emissions of liquid crystal monomers (LCMs) from liquid crystal display (LCD)-associated e-waste dismantling; however, the compositions, priority list, and inventory of LCMs in waste LCD panels remain unknown. Herein, we conducted the first comprehensive identification covering a broader range of LCMs, including 21 biphenyls and analogues (BAs), 28 cyanobiphenyls and analogues (CBAs), and 44 fluorinated biphenyls and analogues (FBAs), in waste television/computer LCD panels. A total of 64 of the 93 target LCMs, including 19 BAs, 6 CBAs, and 39 FBAs, were widely detected in collected waste LCD panels.

Diffusion tensor imaging detects Wallerian degeneration of the corticospinal tract early after cerebral infarction.

To investigate the feasibility and time window of early detection of Wallerian degeneration in the corticospinal tract after middle cerebral artery infarction, 23 patients were assessed using magnetic resonance diffusion tensor imaging at 3.0T within 14 days after the infarction. The fractional anisotropy values of the affected corticospinal tract began to decrease at 3 days after onset and decreased in all cases at 7 days.

[A study on the recurrence of ischemic stroke in nonvalvular atrial fibrillation].

Objective: To study the recurrence of ischemic stroke in patient with nonvalvular atrial fibrillation (NVAF) and to determine the recurrence related factors of ischemic stroke in patients with NVAF.

Methods: The clinical data of 386 NVAF patients with ischemic stroke treated in our hospital from January 1992 to February 2002 were included in this study. The basic clinical information of each patient was recorded.

[Effects of three-stage rehabilitation treatment on acute cerebrovascular diseases: a prospective, randomized, controlled, multicenter study].

Objective: To evaluate the effect of tertiary rehabilitation treatment on acute cerebrovascular diseases.

Methods: Fifteen tertiary rehabilitation networks were set up throughout the country. 1078 patients with acute cerebrovascular diseases were randomly divided into 2 groups: rehabilitation group and control group, out of which 19 patients died, 157 dropped out, and 7 successive evaluations were completed in 902 patients that.

Blindsight modulation of motion perception.

Monkey data suggest that of all perceptual abilities, motion perception is the most likely to survive striate damage. The results of studies on motion blindsight in humans, though, are mixed. We used an indirect strategy to examine how responses to visible stimuli were modulated by blind-field stimuli.
