Analysis of Four Polymorphisms Located at the Promoter of the Estrogen Receptor Alpha ESR1 Gene in a Population With Gender Incongruence [PDF]

open access: yes, 2020
[Abstract] Introduction: Gender incongruence defines a state in which individuals feel discrepancy between the sex assigned at birth and their gender. Some of these people make a social transition from male to female (transwomen) or from female to male ...

Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny [PDF]

open access: yes, 2009
C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad ...

Glutathione increase by the n-butanoyl glutathione derivative (GSH-C4) inhibits viral replication and induces a predominant Th1 immune profile in old mice infected with influenza virus [PDF]

open access: yes, 2019
During aging, glutathione (GSH) content declines and the immune system undergoes a deficiency in the induction of Th1 response. Reduced secretion of Th1 cytokines, which is associated with GSH depletion, could weaken the host defenses against viral ...

Design of singlet fission chromophores with cyclic (alkyl)(amino) carbene building blocks [PDF]

open access: yes, 2019
We use MRSF-TDDFT and NEVPT2 methods to design singlet fission chromophores with the building blocks of cyclic (alkyl)(amino)carbenes (CAACs). CAAC dimers with C2, C4, and p-phenylene spacers are considered.

Macro-Climatic Distribution Limits Show Both Niche Expansion and Niche Specialization among C4 Panicoids [PDF]

open access: yes, 2016
Grasses are ancestrally tropical understory species whose current dominance in warm open habitats is linked to the evolution of C4 photosynthesis. C4 grasses maintain high rates of photosynthesis in warm and water stressed environments, and the syndrome ...

Study of the trace metal ion influence on the turnover of soil organic matter in cultivated contaminated soils [PDF]

open access: yes, 2006
The role of metals in the behaviour of soil organic matter (SOM) is not well documented. Therefore, we investigated the influence of metals (Pb, Zn, Cu and Cd) on the dynamic of SOM in contaminated soils where maize (C4 plant) replaced C3 cultures. Three

Diversity Loss in Coralligenous Structuring Species Impacted by Fishing Gear and Marine Litter

open access: yesDiversity, 2021
Coralligenous structuring species (CSS) form a group of marine megabenthic species with an engineering capacity. Since they are highly vulnerable to anthropogenic activities, they have been selected for the Marine Strategy Framework Directive (MSFD ...

Spectrum of diagnosis of hereditary angioedema: Seven case reports

open access: yesIndian Journal of Allergy Asthma and Immunology, 2020
Hereditary angioedema (HAE) is a potentially life-threatening disorder, due to a mutation in complement one-inhibitor (C1-INH) gene, which blocks the activity of various components of complement – fibrinolytic and bradykinin control system.
