Contribution of migration to replacement of population in Turkey [PDF]

open access: yesMigration Letters, 2016
Relationship between migration and replacement of population has attracted a great deal of scholarly attention. Migration is considered to be a key factor in the growth and replacement of populations. Net migration sometimes exceeds natural change and drive population growth. Migration can compensate for missing births in low-fertility areas, provinces,

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

The Main Cause of Death Following Primary Total Hip and Knee Replacement for Osteoarthritis:A Cohort Study of 26,766 Deaths Following 332,734 Hip Replacements and 29,802 Deaths Following 384,291 Knee Replacements [PDF]

open access: yes, 2017
BACKGROUND: Patients undergoing primary total joint replacement are selected for surgery and thus (other than having a transiently increased mortality rate postoperatively) have a lower mortality rate than age and sex-matched individuals do ...

Five-Year Outcomes of Transfemoral Transcatheter Aortic Valve Replacement or Surgical Aortic Valve Replacement in a Real World Population.

open access: yesCirculation. Cardiovascular Interventions, 2019
BACKGROUND The OBSERVANT study (Observational Study of Effectiveness of SAVR-TAVI Procedures for Severe Aortic Stenosis Treatment) showed that mortality at 1 year is similar after transfemoral transcatheter aortic valve replacement (TAVR) or surgical ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Wolbachia infections that reduce immature insect survival: Predicted impacts on population replacement

open access: yesBMC Evolutionary Biology, 2011
BackgroundThe evolutionary success of Wolbachia bacteria, infections of which are widespread in invertebrates, is largely attributed to an ability to manipulate host reproduction without imposing substantial fitness costs.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Back to replacement migration: A new European perspective applying the prospective-age concept

open access: yesDemographic Research, 2019
Background: The UN Replacement Migration report (2000) had a significant impact in academic and civil society. Its approach consisted of estimating the migration volumes required to mitigate the effects of population decline and ageing.
