Impact of Implant Mesiodistal Distance on Peri-Implant Bone Loss: A Cross-Sectional Retrospective Study.
Clin Implant Dent Relat Res
February 2025
Department of Periodontics and Oral Medicine, The University of Michigan School of Dentistry, Ann Arbor, Michigan, USA.
Purpose: The purpose of this study was to verify the effect of our previously proposed mesiodistal distance for multiple posterior implants on preserving peri-implant bone, and to provide a measurable criterion for predicting implant prognosis.
Methods: One hundred and two patients with dental implants placed in the posterior free-end edentulous arches were recruited in this cross-sectional study. Calibrated X-rays (peri-apical [PA] or bite-wing x-ray) were collected to measure the mesiodistal space as well as the corresponding bone resorption of implants after prosthesis placement.
An Instrument for Evaluating the Self: The Self-Discrepancies Scale in Non-Clinical Participants.
Clin Neuropsychiatry
December 2024
Place du Cardinal Mercier, 10 1348 Louvain-la-Neuve, Belgique.
Objective: The Self-Discrepancies Scale (S-DS) is a multiple-subscore instrument designed to assess discrepancies between mental representations of the self: the actual self on one hand, and the ideal and socially prescribed selves on the other. Its idiographic subscores rely on the endorsement of self-descriptive traits, while its abstract subscores form an overall judgement of felt self-discrepancies. The objectives of the present study were to (i) evaluate the S-DS in a new non-clinical population, (ii) expand the body of data on the S-DS's convergent validity, (iii) study the idiographic data for the S-DS, and (iv) establish a nomothetic list of traits with a better choice of unwanted traits.

Eur J Radiol
December 2024
Department of Radiology and Nuclear Medicine, Maastricht University Medical Centre+, PO Box 5800, 6202 AZ Maastricht, the Netherlands; Mental Health and Sciences (MHeNs) Research Institute, Maastricht University, PO Box 616, 6200 MD Maastricht, the Netherlands.
Objectives: Photon-counting detector CT (PCD-CT) is expected to substantially improve and expand CT-imaging applicability due to its intrinsic spectral capabilities, increased spatial resolution, reduced electronic noise, and improved image contrast. The current study aim is to evaluate PCD-CT efficacy in characterizing bullets based on their dimensions, shape, and material composition.
Materials And Methods: This is an observational phantom study examining 11 unfired, intact bullets of various common calibers, placed in ballistic gelatin.
More twins expected in low-income countries with later maternal ages at birth and population growth.
Hum Reprod
December 2024
Laboratory of Fertility and Well-Being, Max Planck Institute for Demographic Research, Rostock, Germany.
Study Question: How are the changing maternal age structure and population growth expected to shape future twinning rates in low-income countries?
Summary Answer: With maternal age at birth projected to shift toward older ages, twinning rates are also estimated to increase in most low-income countries by 2050 and even more by 2100.
What Is Known Already: Many of the sub-Saharan African and South Asian countries are undergoing, and projected to further experience, the shift of maternal age at birth to older ages. Advanced maternal age is a well-established predictor of multiple births at the individual level, but currently, it is unknown how the changes in maternal age distribution are associated with the changes in twinning rates at the population level in low-income countries.
A role for the kinetochore protein, NUF2, in ribosome biogenesis.
Mol Biol Cell
December 2024
Dept. of Genetics.
Ribosome biogenesis (RB) is an intricate and evolutionarily conserved process that takes place mainly in the nucleolus and is required for eukaryotic cells to maintain homeostasis, grow in size, and divide. Our laboratory has identified the NUF2 protein, part of the mitotic kinetochore, in a genome-wide siRNA screen for proteins required for making ribosomes in MCF10A human breast epithelial cells (Farley-Barnes, 2018). After rigorous validation and using several biochemical and cell-based assays, we find a role for NUF2 in pre-rRNA transcription, the primary and rate-limiting step of RB.
