Scientists warning: we must change paradigm for a revolution in toxicology and world food supply

Author(s): Seralini GE; Jungers G; Andersen A; Antoniou M; Aschner M; Bacon MH; Bertrand M; Bohn T; Bonfleur ML; Bücking E; Defarge N; Djemil R; Domingo JL; Douzelet J; Fagan J; Fournier T; Garcia JLY; Gil S; Hervé-Gruyer P; Hilbeck A; Hilty L; Hub ...

We propose a new paradigm, as toxicology currently lacks the proper perspective. From the 1950s to the 1970s, at least one-third of all toxicological testing in the United States, including for chemicals and drugs, was misleading scientists, and this worldwide issue persists today. Moreover, petr ...

Measurement invariance and differential item functioning of the Functionality Appreciation Scale (FAS) in five latin american nations

Author(s): Mebarak M; Maïano C; Mendoza J; Chirullo V; Coneo AMC; Compte EJ; Cruz-Licea V; Góngora VC; Henríquez C; Martínez-Banfi M; Mejía Rodriguez DL; Pescetto I; Selma H; Boothroyd LG; Thornborrow T; Todd J; Swami V;

The Functionality Appreciation Scale (FAS) is increasingly used within diverse national and linguistic contexts, but assessments of its functioning across groups remains limited. To extend knowledge, we examined measurement invariance of the FAS across five Latin American nations (Argentina, Chil ...

Assessing the performance of a surface washing agent for oil removal from sand in cold environments

Author(s): Sui J; Bi H; Yue R; Fu H; Yang A; An C;

Persistent oil contamination along coastlines can be treated by surface washing agents (SWAs), while low-temperature conditions can significantly impact the effectiveness of SWAs in oil removal. This study investigates the oil removal performance of a commercial SWA for oiled shoreline sand in cold-region environments. Batch oil removal tests were conduct ...

Greater cardiorespiratory fitness is associated with higher cerebral blood flow and lower oxygen extraction fraction in healthy older adults

Author(s): Sanami S; Rezaei A; Tremblay SA; Potvin-Jutras Z; Sabra D; Intzandt B; Gagnon C; Mainville-Berthiaume A; Wright L; Gayda M; Iglesies-Grau J; Nigam A; Bherer L; Gauthier CJ;

Aerobic exercise training promotes cardiovascular, brain and cognitive health. Regular exercise is associated with higher cardiorespiratory fitness, commonly assessed by peak oxygen uptake (VO2peak) during maximal effort testing. Higher cardiorespiratory fitness has been linked to preserved brain ...

Controlling Temozolomide Efficacy by Light-Dependent Inhibition of O sup 6 /sup ‑Methylguanine DNA Methyltransferase

Author(s): Lopez-Miranda IR; Sim JI; Juneau G; Wilds CJ; Beharry AA;

The DNA repair enzyme O6-Methylguanine DNA Methyltransferase (MGMT) is a major contributor in conferring resistance to alkylating agents such as temozolomide (TMZ) in cancers. The use of MGMT inhibitors can suppress resistance and enhance the efficacy of TMZ. However, current inhibitors are nonselective for cancer cells, and as a result, MGMT is also inhi ...

The temporal effects of auditory and visual immersion on speech level in virtual environments

Author(s): Zhang XN; Shamei A; Grond F; Verduyckt I; Bouserhal RE;

Speech takes place in physical environments with visual and acoustic properties, yet how these elements and their interaction influence speech production is not fully understood. While a room's appearance can suggest its acoustics, it is unclear whether people adjust their speech based on this visual information. Previous research shows that higher re ...

Aquatic therapy compared to standard care for chronic low back pain: a randomized controlled trial

Author(s): Vaillancourt N; Montpetit C; Rosenstein B; Fortin M;

Background: Anxiety, depression, and pain-related fears are highly prevalent among individuals with chronic low back pain (CLBP). While aquatic therapy is a promising treatment modality for CLBP, its effects on psychological factors remain poorly understood. Objective: To compare the effects of aquatic therapy (AT) versus standard care (SC) on psychologi ...

Overlap and Covalency in a κN-Arylnitrosyl Cu(II) Metalloradical Formed by Hydroxylamine Oxidative Binding

Author(s): MacKay A; Zsombor-Pindera J; Effaty F; Sheibany N; Gennarini F; Habibian M; Chen F; Askari MS; Brytskyi M; Kroeker S; Kennepohl P; Ottenwaelder X;

Redox noninnocent ligands present opportunities to access reactive metal-radical complexes, but competing redox pathways often hinder their selective formation. Here, a pentadentate arylhydroxylamine-containing (ArNHOH) ligand directs copper salts to form a single, well-defined CuII-arylnitrosyl ...

Synthesis and Acidic pH-Responsive Disassembly of Dual-Location Shell-Sheddable/Core-Degradable Block Copolymer Nanoassemblies and Their Controlled Drug Delivery

Author(s): Andrade-Gagnon B; Casillas-Popova SN; Shamekhi M; Bairagi K; Peslherbe GH; Oh JK;

The development of acidic pH-responsive degradable amphiphilic block copolymers (ABPs) and their nanoassemblies has been extensively explored as a promising platform for tumor-targeting drug delivery and cancer therapy. Despite tremendous advances, most acidic pH-degradable ABP nanoassemblies have been designed with acid-labile groups positioned in a sing ...

Spatiotemporal Evolution and Anomaly Assessment of Wildfire-Induced Air Pollution Across Canada Using Satellite AOD Analysis

Author(s): Su Y; Wang Z; Fu H; Yang A; Chen X; An C;

The 2023 wildfires caused serious riks to air quality and public health across various provinces in Canada, particularly during the period from May to June. This study aims to systematically evaluate the impact of the May-June wildfire events on air pollution in Canada using satellite Aerosol Optical Depth (AOD) data, along with the Hybrid Single-Particle ...
