Vascular Research Reveals Link to ASD Symptoms

Restoring the proper function of endothelial cells in the brain may offer a novel way to alleviate behavioral symptoms connected to autism spectrum disorder (ASD), according to new research published in the journal Neuron (DOI: 10.1016/j.neuron.2026.09.009).

Led by former doctoral student Julie Ouellette, the study examined how vascular dysfunction during early brain development impacts later behavior. Endothelial cells typically enable blood to swiftly reach active areas of the brain. However, in models featuring autism-associated mutations, such as the 16p11.2 deletion, these cells fail to react with sufficient speed.

Early Brain Development and Next Steps

The research links this early vascular impairment directly to later behavioral issues, including motor learning difficulties, repetitive movements, and hyperactivity. Identifying a method to restore appropriate endothelial cell activity presents a potential approach to treating these symptoms.

Demonstrations Erupt Nationwide Over Federal Policy Changes

Demonstrators gathered in Vancouver and across Canada on Sunday to challenge federal measures aimed at curbing the nation’s temporary resident population. The rallies, organized by the Migrant Rights Network across 11 locations including British Columbia, Ontario, Quebec, and Prince Edward Island, occurred just ahead of Parliament’s resumption.

Federal policy changes introduced in 2024 have established tighter regulations for temporary foreign workers and set caps on study permits. The government aims to shrink non-permanent residents from a peak of 7.6 per cent of the population in October 2024 to below five per cent by late 2027, citing pressure on healthcare, housing, and public services. Parliamentary Budget Officer data shows net inflows of non-permanent residents reached nearly 800,000 in 2023.

Local Rallies Highlight Community Impacts

In Vancouver, advocates and residents assembled at Memorial South Park, symbolically bashing a piñata representing Bill C-12, recent federal legislation tightening asylum and immigration rules. Local rally participants expressed deep concern that shifting federal policies leave workers facing deportation, expiring permits, and difficult working conditions despite having followed official processes.

Organizers are urging Ottawa to provide permanent status to migrants currently in the country, auto-renew study and work permits, halt deportations, and eliminate employer-tied permits. Campaign materials from the Migrant Rights Network argued that blaming migrants fails to address rising rents, healthcare pressures, or wage issues, warning that policy shifts risk dividing workers.

CFIA Issues Warning for Alasko Brand Raspberries

Health officials are advising the public not to consume, sell, or serve specific Alasko brand frozen, whole raspberries across seven provinces. The Canadian Food Inspection Agency (CFIA) launched a foodborne illness outbreak investigation that triggered the recall after illnesses linked to the consumption of these items were reported.

The advisory applies to products bearing the lot number LOT# SY25314, purchase order code PO#138602, and a best before date of Nov. 10, 2027. Distributed broadly, these frozen berries reached households as well as hotels, institutions, and restaurants.

Norovirus Symptoms and Health Guidance

The recall stems from potential norovirus contamination. The highly contagious virus causes vomiting and diarrhea, with symptoms typically appearing as early as 12 hours following exposure. Additional symptoms often include stomach pain, nausea, cramps, headache, muscle aches, fatigue, chills, and a low-grade fever.

While no prescription treatments exist for norovirus, most individuals recover within two to three days without enduring lasting health impacts. However, severe vomiting or diarrhea can lead to dehydration. The Public Health Agency of Canada advises affected individuals to drink plenty of fluids, noting that severe cases may require hospitalization for intravenous fluid administration. Anyone who suspects they became ill from these products should reach out to their health-care provider.

Ongoing Investigation and Disposal Instructions

Specific details regarding the location of the outbreak or the total count of sick individuals have not been disclosed. The CFIA is verifying that the marketplace removes affected items and noted that its ongoing investigation could trigger additional product recalls. Consumers and businesses holding the recalled raspberries should either throw them away or return them to the place of purchase.
