The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Determinants of medical borrowing and associated inequalities in the Kingdom of Saudi Arabia: evidence from the Global Findex survey

open access: yesHealth Economics Review
Background While out-of-pocket health expenses continue to rise, households’ coping strategies remain largely unexplored. When individuals and families rely on unsustainable mechanisms such as borrowing, they may face heightened financial vulnerability ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The Lorenz curve in economics and econometrics [PDF]

open access: yes
This paper surveys selected applications of the Lorenz curve and related stochastic orders in economics and econometrics, with a bias towards problems in statistical distribution theory. These include characterizations of income distributions in terms of

Urban Concentration and Spatial Allocation of Rents from natural resources. A Zipf's Curve Approach

open access: yesREGION, 2017
This paper aims at demonstrating how countries' dependency on natural resources plays a crucial role in urban concentration. The Zipf's Curve Elasticity is estimated for a group of countries and related to a set of indicators of unilateral transferences.

Sound concentration caused by curved surfaces [PDF]

open access: yesProceedings of Meetings on Acoustics, 2013
In room acoustics, the focusing effect of reflections from concave surfaces is a well-known problem. The occurrence of concave surfaces has tended to increase in modern architecture, due to new techniques in design, materials, and manufacturing. Focusing can cause high sound pressure levels, sound coloration, or an echo.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Concentration curve of income factors.

open access: yes
Note: In the depicted figure, the x-axis indicates the population distribution across quantiles, while the y-axis shows the income distribution. The Lorenz curve for income is denoted by L(y, p), whereas L(w, p) and L(π, p) represent the concentration ...

The Forms of Antagonism Curves as Affected by Concentration [PDF]

open access: yesBotanical Gazette, 1914
A study of the literature shows that the effect of concentration on the form of the antagonism curve is not fully appreciated. The alterations in the form of the curve are very marked when solutions are diluted to one-half strength. The writer has found this to be the case with antagonism curves of different types obtained by using a great variety of ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
