A model for specific interactions of manganese-phthalocyanine in protic media

open access: yesEclética Química, 2018
Extinction coefficients (e) changes of manganese phthalocyanine (Mn-Pc) were studied in different organic solvents and related to solvent polarity scales (Kosower's values (Z), Dimroth's values (ET), donor numbers (DN) and linear solvation energy ...

Methyltrioctylammonium Octadecanoate as Lubricant Additive to Different Base Oils

open access: yesLubricants, 2022
This study investigates the use of an ionic liquid obtained from fatty acids (FAIL) as an additive at 2 wt.% in two different base oils: a mineral oil (M1) and a polyol ester (E1).

The Predominance Of Dust In The Polar Region Of Agn

open access: yes, 2016
Recent mid-infrared (MIR) interferometric observations showed in few AGN that the bulk of the infrared emission originates from the polar region above the putative torus, where only little dust should be present. Our investigation of 149 Seyferts with high angular resolution MIR images from, e.g., VLT/VISIR shows that significant polar dust emission ...

Predominance of Th2 polarization by Vitamin D through a STAT6-dependent mechanism [PDF]

open access: yesJournal of Neuroinflammation, 2011
AbstractBackgroundVitamin D has several reported immunomodulatory properties including the reduced generation of pro-inflammatory CD4+ T helper 1 (Th1) cells and the increase in levels of the anti-inflammatory Th2 subset. Less clear has been the impact of vitamin D on the pro-inflammatory Th17 subset, and whether and how vitamin D may preferentially ...

Polarity switching of ovarian cancer cell clusters via SRC family kinase is involved in the peritoneal dissemination [PDF]

open access: yes, 2022
Peritoneal dissemination is a predominant pattern of metastasis in patients with advanced ovarian cancer. Despite recent progress in the management strategy, peritoneal dissemination remains a determinant of poor ovarian cancer prognosis.

Petal Cellular Identities

open access: yesFrontiers in Plant Science, 2021
Petals are typified by their conical epidermal cells that play a predominant role for the attraction and interaction with pollinators. However, cell identities in the petal can be very diverse, with different cell types in subdomains of the petal, in ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Solubilidade das substâncias orgânicas

open access: yesQuímica Nova, 2013
The solubility of organic compounds is a topic of great importance in chemistry and of interest in several areas, such as materials, drugs and the environment. In this paper, the solubility of these species is discussed in terms of their properties, such
