Integrated Chemoenzymatic Synthesis of the mRNA Vaccine Building Block N1‐Methylpseudouridine Triphosphate

open access: yesAngewandte Chemie International Edition, Accepted Article.
Pseudouridine‐5’‐triphosphate (ΨTP) and the N1‐methylated derivative (m1ΨTP) are critical monomer building blocks of the currently used mRNA vaccines, yet efficient methods of their synthesis from readily accessible substrates remain underdeveloped. We herein report notably atom‐economic and high‐yielding biocatalytic route toward ΨTP (83% yield) and ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

open access: yesHepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Metabolisms of Nucleosides in Bacteria

open access: yesAgricultural and Biological Chemistry, 1965
Pyrimidine nucleoside phosphorylases obtained from Er. carotovora and Cor. sepedonicum were purified by means of ammonium sulfate fractionation and DEAE-cellulose column chromatography. Some properties of these enzyme were also studied. The enzyme from Cor.

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

open access: yesThe Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Genomic Insights Into a Strong Biofilm‐Forming Enterococcus faecalis MTR_EFS01 Strain Isolated From a Shrimp in Bangladesh

open access: yesAnimal Research and One Health, EarlyView.
This study characterizes a multidrug‐resistant and strong biofilm‐forming Enterococcus faecalis strain obtained from a shrimp sample in Bangladesh. ABSTRACT Enterococcus faecalis is known for its ability to form strong biofilms and its role as an opportunistic pathogen. In this study, we screened and characterized a multidrug‐resistant (MDR) and strong

Incorporation of tritiated cytidine into ribonucleic acid by isolated pea nuclei [PDF]

open access: yes, 1962
A new method for the isolation of the nuclei from plant tissue has been devised. This method consists in passing the plant tissue through a set of spring-loaded, counter-rotating rollers and collecting the liberated nuclei in sucrose solution containing ...
