An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Genetic Relationship of Body Energy and Blood Metabolites with Reproduction in Holstein Cows [PDF]

open access: yes, 2008
Body condition score (BCS), energy content (EC), cumulative effective energy balance (CEEB), and blood serum concentrations of glucose, beta-hydroxybutyrate (BHBA), and nonesterified fatty acids ( NEFA) were measured throughout first lactation in 497 ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Performances de reproduction du dromadaire. Base empirique

open access: yesRevue d’élevage et de médecine vétérinaire des pays tropicaux, 1989
Cet article est une synthèse des données empiriques et des observations provenant la plupart d'études de terrain sur les performances de reproduction du dromadaire. Des références sont faites à de nombreux pays d'Afrique et d'Asie. L'âge élevé à la première parturition (60 mois), le long intervalle entre les mises bas (24 mois et plus) et la réforme ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Caractéristiques de la reproduction chez le zébu, étudiées au Centre de Recherches Zootechniques de Dahra

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1973
Dans ce rapport, il est tenté de faire le point sur les diverses caractéristiques actuellement connues de la reproduction chez le zébu Gobra. Sont analysés successivement l'âge au 1er vêlage, l'intervalle entre les vêlages, les problèmes posés par l ...

The Shape of the Trade-Off Function Between Reproduction and Future Performance in \u3cem\u3ePlantago major\u3c/em\u3e and \u3cem\u3ePlantago rugelii\u3c/em\u3e [PDF]

open access: yes, 2002
There is a paucity of data describing the nature of the trade-off function between reproduction and future performance. Most studies implicitly assume it is a linear function such that allocation of resources to reproduction results in a proportional ...

Climate warming may affect the optimal timing of reproduction for migratory geese differently in the low and high Arctic

open access: yesOecologia, 2019
Rapid climate warming is driving organisms to advance timing of reproduction with earlier springs, but the rate of advancement shows large variation, even among populations of the same species.

High Temperature, pH, and Hypoxia Cause Oxidative Stress and Impair the Spermatic Performance of the Amazon Fish Colossoma macropomum

open access: yesFrontiers in Physiology, 2020
The control of abiotic parameters is fundamental for fish survival, growth and reproduction. These factors have a direct effect on sperm quality. Thus, this study evaluated the effect of different temperatures (29, 31, 33, and 35°C), pHs (4 and 8), and ...
