Hearing loss is associated with decreased default-mode network connectivity in individuals with mild cognitive impairment

Author(s): Grant N; Phillips N;

Mild cognitive impairment (MCI) and hearing loss (HL) have been separately associated with increased dementia risk. These highly co-occurring dementia risk factors are associated with aberrant functional brain connectivity. In individuals with HL aberrant functional connectivity has been associated with cognitive impairment. In individuals with MCI, aberr ...

Hemodynamic correlates of fluctuations in neuronal excitability: A simultaneous Paired Associative Stimulation (PAS) and functional near infra-red spectroscopy (fNIRS) study

Author(s): Cai Z; Pellegrino G; Spilkin A; Delaire E; Uji M; Abdallah C; Lina JM; Fecteau S; Grova C;

Background: The relationship between task-related hemodynamic activity and brain excitability is poorly understood in humans as it is technically challenging to combine simultaneously non-invasive brain stimulation and neuroimaging modalities. Cortical excitability corresponds to the readiness to ...

Multi-stimuli-responsive degradable boronic ester-crosslinked e-spun nanofiber wound dressings

Author(s): Casillas-Popova SN; Lokuge ND; Singh P; Cirillo A; Thinphang-Nga A; Skinner CD; Vuckovic D; Findlay BL; Oh JK;

Owing to their high aspect ratio of length to diameter, large surface area, large pore size, and high molecular orientation, electro-spun (e-spun) nanofibrous mats have been explored as effective nanomaterials for various applications, including wound dressings and healing materials. Of particula ...

Metal Exposure, Bioaccumulation, and Toxicity Assessment in Sediments from the St. Lawrence River Before and After Remediation Using a Resuspension Technique

Author(s): Javid M; Mulligan CN; Lefranc M; Rosabal Rodriguez M;

This study, using Hyalella azteca and Chironomus riparius, evaluated the effects of exposure to heavy metal-contaminated sediments collected from the study area under three conditions: before remediation, after remediation, and suspended particulate matter (SPM). The selected toxicity tests allowed for the evaluation of biological responses across varying ...

Unveiling the hidden chronic health risks of nano- and microplastics in single-use plastic water bottles: A review

Author(s): Sajedi S; An C; Chen Z;

Single-use plastic products, such as water bottles, have become ubiquitous in modern society, contributing significantly to the growing problem of plastic waste in landfills, rivers, oceans, and natural habitats. This poses severe threats to biodiversity and ecosystem stability. The emergence of microplastics (1 µm to 5 mm) and nanoplastics (less than 1 µ ...

Unraveling the resuspension and transformation of stranded oil: Mechanisms driving oil-particle aggregate formation in intertidal zones

Author(s): Yang X; Bi H; Huang G; Zhang H; Lyu L; An C;

The intertidal zone, serving as a dynamic interface, presents a challenging environment for understanding the transport of spilled oil. This study explores the resuspension of stranded oil and the formation of suspended oil-particle aggregates (OPAs) under varying sediment properties, water chemistry, hydrodynamic forces, and biodegradation conditions. Fi ...

Printing of Cantilevers and Millifluidic Devices Using Ultrasound Waves

Author(s): Foroughi S; Karamzadeh V; Habibi M; Packirisamy M;

Direct sound printing (DSP) is a recent development in additive manufacturing processes using sound waves, in which cavitation bubbles created by a focused ultrasound field polymerize the liquid resin via the sonochemistry route. This article presents the first attempt to create functional parts, such as cantilevers and millifluidic systems in polydimethy ...

Is Adipose Tissue Inflammation the Culprit of Obesity-Associated Comorbidities?

Author(s): Turner L; Wanasinghe AI; Brunori P; Santosa S;

In individuals with obesity, the onset of chronic comorbidities coincides with the excessive accumulation of adipose tissue in various tissue beds. As obesity progresses, adipose tissue becomes increasingly dysfunctional causing chronic low-grade inflammation. Indeed, adipose tissue inflammation, which partially stems from macrophage infiltration and expr ...
