A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Spatial structure of m- and o-substituted isologous aryl cyanates

, 2020
1. m-Substituted isologous phenyl cyanates exist in solution as mixtures of the syn- and anti-forms. The fraction of the latter, as well as the dihedral angles between the planes of the aromatic ring and CarECN, increase with the increasing acceptor ...

Hydrothermal origin of metabolic phosphorylation

The FEBS Journal, EarlyView.
Serpentinizing hydrothermal vents are candidate sites for biochemical origins. They generate extremely reducing conditions, depositing phosphite (HPO32−) and transition metals, including palladium, in the native (zero‐valent) state. Schlikker et al.

Polarizability anisotropy and spatial structures of aryl cyanates [PDF]

, 1981
1. The polarizability parameters of the cyanate group have been determined. 2. Phenyl cyanate and p-methoxyphenyl cyanate possess a planar, and p-chloro-p-bromo-, and nitrophenyl cyanates possess a nonplanar, conformation in solutions.

The isomerization of ammonium cyanates. II* The kinetics of isomerization of ammonium and alkylammonium cyanates in dimethyl sulphoxide-water mixtures

, 1977
The kinetics of the isomerizations of ammonium, methylammonium and ethylammonium cyanates to urea, methylurea and ethylurea have been studied in aqueous dimethyl sulphoxide over the range 0-100% dimethyl sulphoxide.

Formation of new thermosets by the reaction of cyanates with thiophenols

, 2022
S.8-17Sulfur-containing aromatic thermosets, mainly consisting of aryloxy- and arylthio-substituted 1,3,5-triazines, have been prepared through the reaction of difunctional cyanates with mono- and difunctional aromatic thiols.

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope
In contrast to the simple and straightforward generation of pyridinium cations, the P‐alkylation of the heavier homolog λ3σ2‐phosphinines is more challenging due to their weak nucleophilicity, as demonstrated only by a handful of examples. The previously

Periodontitis and Rheumatoid Arthritis—Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
Periodontitis and rheumatoid arthritis are linked via the two‐hit model whereby early periodontal inflammation can lead to autoantibody production capable of interacting with inflamed synovial tissues. Subsequent systemic inflammation can exacerbate the periodontal inflammatory response and bacterial dysbiosis leading to further autoantibody production

The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

The Journal of Physiology, EarlyView.
Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained
