Derivation of a health‐based guidance value for Δ8‐tetrahydrocannabinol (Δ8‐THC) and its occurrence in food

EFSA Journal, Volume 23, Issue 11, November 2025.
Abstract The European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the derivation of a health‐based guidance value (HBGV) for Δ8‐tetrahydrocannabinol (Δ8‐THC) in food with an assessment of the occurrence of Δ8‐THC and the co‐occurrence with Δ9‐THC in hemp and hemp‐derived products.

On the A. malaris of the Common Squirrel Monkey (Saimiri sciureus)

Okajimas Folia Anatomica Japonica, 1989
Detailed observations were made of the a. malaris in 11 adult common squirrel monkeys (Saimiri sciureus) utilizing the plastic injection method. The malar artery was well-developed in all 21 examples observed and arose medially from the infraorbital artery proximal to the entrance of the infraorbital canal and lateral to the obliquus inferior muscle ...

Relationships Between Intra‐Spinal Resting‐State Functional Connectivity and Electrophysiology Following Spinal Cord Injury

Human Brain Mapping, Volume 46, Issue 14, 01 October 2025.
Unilateral spinal cord injury in monkeys induces widespread and dynamic changes in resting‐state functional connectivity (rsFC), mirroring alterations in local field potential (LFP) coherence. Our findings reveal spatially and temporally complex intraspinal plasticity, supporting rsFC as a potential electrophysiologically grounded biomarker for ...

Assessing Gestation and Fetal Sex in Wild Assamese Macaques Using Urinary Estrogen Analysis

American Journal of Primatology, Volume 87, Issue 8, August 2025.
Postable Summary: Urinary estrogen marks pregnancy in wild macaques, with limited use for sexing fetuses. ABSTRACT In mammals, estrogens and progestogens are crucial for gestation, fetal development, and maternal preparation for parturition and lactation.
