Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

Advanced Science, EarlyView.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...

Critical vulnerabilities of food selections based on nutrient content claims and reference amounts of food and creating a reliable procedure

Food Production, Processing and Nutrition
Computing the food component (nutrient) amount in 100 kilocalories, 100 grams or 100 milliliters, the reference amount customarily consumed (RACC), or 50 grams of food demonstrates the food component amount of some foods unsuitably.

NutriBench: A Dataset for Evaluating Large Language Models on Nutrition Estimation from Meal Descriptions [PDF]

arXiv
Accurate nutrition estimation helps people make informed dietary choices and is essential in the prevention of serious health complications. We present NutriBench, the first publicly available natural language meal description nutrition benchmark. NutriBench consists of 11,857 meal descriptions generated from real-world global dietary intake data.

Unraveling Neurodevelopment: Synergistic Effects of Intrinsic Genetic Programs and Extrinsic Environmental Cues

Advanced Science, EarlyView.
Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

Dual‐templating surface gel into thin SSZ‐13 zeolite membrane for fast selective hydrogen separation

Aggregate, Volume 3, Issue 6, December 2022., 2022
Submicron SSZ‐13 zeolite membranes in high continuity were synthesized from dual‐templated surface gels. The templates directed and regulated the crystallization of the SSZ‐13 zeolite, and the surface gel determined the thickness of the membrane.

An Insect Salivary Sheath Protein Triggers Plant Resistance to Insects and Pathogens as a Conserved HAMP

Advanced Science, EarlyView.
The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

A Facile Strategy to Restore the Optic Nerve Functionality Using an Injectable Conducting Hydrogel

Advanced Science, EarlyView.
An injectable conductive polymer hydrogel from poly (3,4‐ethylenedioxythiophene) (PEDOT) is developed to facilitate the recovery of electrophysiological function in injured optic nerve. The hydrogel can be injected directly at the injury site and spontaneously gel in place.

Functional traits mediate individualistic species‐environment distributions at broad spatial scales while fine‐scale species associations remain unpredictable

American Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022
Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...
