Unveiling the Movement of RanBP1 During the Cell Cycle and Its Interaction with a Cyclin-Dependent Kinase (CDK) in Plants.

In the flower development study, we identified SCI1 (Stigma/style Cell-cycle Inhibitor 1), a regulator of cell proliferation. SCI1 interacts with NtCDKG;2 ( Cyclin-Dependent Kinase G;2), a homolog of human CDK11, which is responsible for RanGTP-dependent microtubule stabilization, regulating spindle assembly rate. In a Y2H screening of a cDNA library using NtCDKG;2 as bait, a RanBP1 (Ran-Binding Protein 1) was revealed as its interaction partner.

Gyrfalcon Prey Abundance and Their Habitat Associations in a Changing Arctic.

Arctic habitats are changing rapidly and altering trophic webs and ecosystem functioning. Understanding how species' abundances and distributions differ among Arctic habitats is important in predicting future species shifts and trophic-web consequences. We aimed to determine the habitat-abundance relationships for three small herbivores on the Seward Peninsula of Alaska, USA by fitting data from 983 point counts (collected during 2019, 2021, and 2022) with N-mixture models that account for imperfect detection.

A comparative approach to the microstructure in the carpus and tarsus in anurans.

Despite the significant literature about morphological features of limb skeletons involved in tetrapod limb evolution, some questions about carpal and tarsal elements remain. In anurans, the ecomorphological and biomechanical approaches studied long hind limbs (to jump) and forelimbs (to land) and emphasized the role of the long bones in locomotion but disregarded what happens with the nodular elements of the carpus and tarsus. Here, we present a comparative study of nodular elements of the carpus and tarsus in anurans based on whole-mount specimens stained with Alcian Blue (cartilage) and Alizarin Red S (bone and calcified cartilage).

Prevalence and quality of life associated with erectile dysfunction and lower urinary tract symptoms: a cross-sectional study.

Background: Genitourinary health significantly affects the quality of life of men, particularly those in middle age. Recent studies have shown that more than half of the men aged over 40 years experience some degree of low urinary tract symptoms (LUTS) or erectile dysfunction (ED).

Objective: To assess the prevalence of ED and LUTS in middle-aged men and correlate this with quality of life data.
