Risk-Taking Behavior and Its Impact on Treatment, Vaccination and Diagnosing [PDF]

open access: yes, 2015
We present results from two recent mathematical biology studies that address the effect of risk-taking behavior on epidemic models. We show that when risk-taking prevails over riskavoidance, it is possible to show a detrimental and counterintuitive ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Postpartum uterine diseases in dairy cows : a review with emphasis on subclinical endometritis [PDF]

open access: yes, 2016
In this review, updated and precise definitions of the most common postpartum uterine diseases in dairy cows are provided. An aberrant uterine environment at inappropriate stages of the reproductive cycle inflicts damage to gametes and zygotes, impairing

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

A Right to Choose?: Sex Selection in the International Context [PDF]

open access: yes, 2007
While there is some debate among doctors, ethicists, and the general public about the level of medical necessity that should justify a sex-selection procedure, most accept that sex selection for medical reasons is beyond ethical reproach, and in some ...

The time has come to make cervical cancer prevention an essential part of comprehensive sexual and reproductive health services for HIV-positive women in low-income countries. [PDF]

open access: yes, 2015
IntroductionHIV and cervical cancer are intersecting epidemics that disproportionately affect one of the most vulnerable populations in the world: women in low- and middle-income countries (LMICs).

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Trends and factors associated with skilled birth attendance in a post-Ebola context: DHS Guinea 2018

open access: yesJournal of Public Health in Africa
Background: In Guinea, the 2013–2015 Ebola epidemic profoundly affected maternal health service use. The frequency of births attended by skilled health professionals in the post-Ebola context remains under-documented.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Reproductive value, the stable stage distribution, and the sensitivity of the population growth rate to changes in vital rates [PDF]

open access: yes
The population growth rate, or intrinsic rate of increase, measures the potential rate of growth of a population with specified and fixed vital rates.The sensitivity of population growth rate to changes in the vital rates can be written in terms of the ...
