Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

open access: yesAdvanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

Conversion of glutamate carbon to fatty acid carbon via citrate in rat epididymal fat pads

open access: yesJournal of Lipid Research, 1964
The incorporation of the C14 of glutamate-2-C14 and glutamate-5-C14 into fatty acids by epididymal fat pads and liver slices suggests the operation of the following metabolic pathway: α-ketoglutarate → isocitrate → cis-aconitate → citrate → acetyl CoA ...

Preferential Concentration of C14 in Posterior Pituitary Following Hydrocortisone C14 Injection.

open access: yesExperimental Biology and Medicine, 1959
SummaryHydrocortisone 4-C14 was injected into rats, guinea pigs, and rabbits, and distribution of C14, 30 minutes after injection was studied. Activity was widely distributed and the results were variable; but in most experiments, activity (cts/min/mg tissue) was higher in the posterior pituitary gland than in any other tissue. Activity in the anterior

Beyond PEG: Emerging Polymer Lipid Alternatives for Lipid Nanoparticle (LNP) Formulations

open access: yesAdvanced Science, EarlyView.
This review discusses recent advances in PEG‐alternative LNP designs, including non‐PEG polymers, zwitterionic lipids, and polypeptides. It evaluates how surface‐engineering chemistry influences LNP formation and biological behavior, and highlights current limitations and opportunities of PEG‐alternative LNPs.

Nicotinamide riboside and pterostilbene reduces markers of hepatic inflammation in NAFLD: A double‐blind, placebo‐controlled clinical trial

open access: yesHepatology, EarlyView., 2022
NRPT 1X reduces ALT and ceramide 14:0 in 65% of subjects as compared to only 28% in the placebo group. Abstract Background and Aims The prevalence of NAFLD is increasing globally and on a path to becoming the most frequent cause of chronic liver disease. Strategies for the prevention and treatment of NAFLD are urgently needed.

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

open access: yesAdvanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections

open access: yesAdvanced Electronic Materials, EarlyView.
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

Presence of glycerokinase in guinea pig mammary gland and the incorporation of glycerol into glycerides

open access: yesJournal of Lipid Research, 1964
The presence of glycerokinase in homogenates of mammary tissue from lactating guinea pigs is demonstrated. It has been shown that α-glycerophosphate-C14 (chromatographically identified) is formed from glvcerol-1,3-C14 in the presence of homogenate.
