Differential changes in the morphology and fuel loads of obligatory and partial migrant passerines over half a century in Britain.

Migratory distances and stopover locations are changing for many passerines in response to climate change. Morphological changes have been linked to rising global temperatures in both migrants and residents, but the implications of these changes on fuel loads, and associated flight ranges are little studied. Wing length and body mass changes between 1964 and 2020 were calculated for 15 migrant and partially migrant passerines in Britain.

Mechanism of structure-specific DNA binding by the FANCM branchpoint translocase.

FANCM is a DNA repair protein that recognizes stalled replication forks, and recruits downstream repair factors. FANCM activity is also essential for the survival of cancer cells that utilize the Alternative Lengthening of Telomeres (ALT) mechanism. FANCM efficiently recognizes stalled replication forks in the genome or at telomeres through its strong affinity for branched DNA structures.

The Eyes Absent family: At the intersection of DNA repair, mitosis, and replication.

The Eyes Absent family (EYA1-4) are a group of dual function proteins that act as both tyrosine phosphatases and transcriptional co-activators. EYA proteins play a vital role in development, but are also aberrantly overexpressed in cancers, where they often confer an oncogenic effect. Precisely how the EYAs impact cell biology is of growing interest, fuelled by the therapeutic potential of an expanding repertoire of EYA inhibitors.

The Role of Telemedicine in Voice Therapy.

During the COVID-19 pandemic, our institution adopted telemedicine for voice therapy (VT) as an alternative to in-person sessions, which has been integrated into our routine practice following the pandemic. This study aims to explore factors influencing completion rates among the 2 methods. A retrospective chart review at a single tertiary care institution between 2019 and 2021 was conducted.

Deregulated DNA ADP-ribosylation impairs telomere replication.

The recognition that DNA can be ADP ribosylated provides an unexpected regulatory level of how ADP-ribosylation contributes to genome stability, epigenetics and immunity. Yet, it remains unknown whether DNA ADP-ribosylation (DNA-ADPr) promotes genome stability and how it is regulated. Here, we show that telomeres are subject to DNA-ADPr catalyzed by PARP1 and removed by TARG1.
