Isomerism and Isomerization of Organic Compounds [PDF]

open access: yesNature, 1949
THIS little book presents the material of lectures delivered by the author during 1945–46, and deals only with those aspects if its subject which have most interested him. This limitation is made clear in the preface, and the would-be reader should not be misled by the wide title of the book into expecting even an outline of the whole field. The book a

Space and Culture: Isomerism in Vernacular Dwellings in Meizhou, Guangdong Province, China

open access: yesJournal of Asian Architecture and Building Engineering, 2018
Taking Hakka vernacular dwellings as an example, this paper discusses the relationship between culture and architectural form. Using survey data from 2,189 traditional villages in the Meizhou region, the authors identify seven types of dwelling and their

Fetal Heterotaxy with Tricuspid Atresia, Pulmonary Atresia, and Isomerism of the Right Atrial Appendages at 22 Weeks

open access: yesAmerican Journal of Perinatology Reports, 2013
We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex ...

Spontaneous Left Cardiac Isomerism in Chick Embryos: Case Report, Review of the Literature, and Possible Significance for the Understanding of Ventricular Non-Compaction Cardiomyopathy in the Setting of Human Heterotaxy Syndromes

open access: yesJournal of Cardiovascular Development and Disease, 2019
The outer shape of most vertebrates is normally characterized by bilateral symmetry. The inner organs, on the other hand, are normally arranged in bilaterally asymmetric patterns.

Distributed Polarizability Model for Covalently Bonded Fullerene Nanoaggregates: Origins of Polarizability Exaltation

open access: yesNanomaterials, 2022
Polarizability exaltation is typical for (C60)n nanostructures. It relates to the ratio between the mean polarizabilities of (C60)n and C60: the first one is higher than the n-fold mean polarizability of the original fullerene. This phenomenon is used in

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Bis(3-aminobenzenesulfonato-N)-diaqua-bis(N,N’-dimethylformamide-O)-copper(II)

open access: yesMolbank, 2023
Reaction of 3-aminobenzenesulfonic acid (HL1) with Cu(NO3)2·2.5H2O in H2O/DMF leads to the formation of the new bis(3-aminobenzenesulfonato-κN)-diaqua-bis(dimethylformamide-κO)-copper(II) complex [Cu(L1)2(DMF)2(H2O)2] (1) (HL1 = 3-aminobenzenesulfonic ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
