Introduction: Women with early bilateral salpingo-oophorectomy (BSO) have greater Alzheimer's disease (AD) risk than women with spontaneous menopause (SM), but the pathway toward this risk is understudied. Considering associative memory deficits may reflect early signs of AD, we studied how BSO affected brain activity underlying associative memory.

Methods: Early midlife women with BSO (with and without 17β-estradiol therapy [ET]) and age-matched controls (AMCs) with intact ovaries completed a face-name associative memory task during functional magnetic resonance imaging.

Acad Radiol

December 2024

Division of Nuclear Medicine and Molecular Imaging, Department of Medical Imaging, Geneva University Hospital, CH-1211 Geneva 4, Switzerland (H.A., H.Z.); Department of Nuclear Medicine and Molecular Imaging, University of Groningen, University Medical Center Groningen, 9700 RB Groningen, Netherlands (H.Z.); Department of Nuclear Medicine, University of Southern Denmark, Odense, Denmark (H.Z.); University Research and Innovation Center, Óbuda University, Budapest, Hungary (H.Z.). Electronic address:

Background: While magnetic resonance imaging (MRI) remains the gold standard for morphological imaging, its ability to differentiate between tumor tissue and treatment-induced changes on the cellular level is insufficient. Notably, glioma cells, particularly glioblastoma multiforme (GBM), demonstrate overexpression of chemokine receptor-4 (CXCR4). This study aims to evaluate the feasibility of non-invasive Ga-Cixafor™ PET/CT as a tool to improve diagnostic accuracy in patients with high-grade glioma.

Biosynthesis of Antimicrobial Ornithine-Containing Lacticin 481 Analogues by Use of a Combinatorial Biosynthetic Pathway in .

ACS Synth Biol

December 2024

Department of Molecular Genetics, Groningen Biomolecular Sciences and Biotechnology Institute, University of Groningen, Groningen 9747 AG, The Netherlands.

Lacticin 481, a ribosomally synthesized and post-translationally modified peptide (RiPP), exhibits antimicrobial activity, for which its characteristic lanthionine and methyllanthionine ring structures are essential. The post-translational introduction of (methyl)lanthionines in lacticin 481 is catalyzed by the enzyme LctM. In addition to macrocycle formation, various other post-translational modifications can enhance and modulate the chemical and functional diversity of antimicrobial peptides.

EClinicalMedicine

September 2024

Department of Clinical Science and Education, Södersjukhuset, Karolinska Institutet, Sjukhusbacken 10, 118 83, Stockholm, Sweden.

Article Synopsis
  • Chronic obstructive pulmonary disease (COPD) can be influenced by genetic factors and may stem from reduced lung growth during childhood, leading to lower lung function throughout life.
  • A polygenic risk score (PRS) was calculated using data from a large genome-wide association study and tested for its correlation with lung function in individuals aged 4-50 from multiple research cohorts.
  • Results indicated that higher PRS scores were associated with significantly lower lung function, measured by key indicators, starting from childhood and continuing into adulthood, regardless of smoking, sex, or asthma diagnosis.

Background & Aims: Smell and taste changes are frequently reported bothersome treatment symptoms during treatment for childhood cancer and assumed to influence outcomes such as food intake. Since nutritional status of children with cancer is already vulnerable, any detrimental effects on food intake should be prevented. Therefore, understanding the exact relationship between chemosensory changes and dietary intake, eating behavior, and other domains such as health-related quality of life (HRQoL), is important for improving outcomes.
