Effect of extracellular vesicles derived from oviductal and uterine fluid on the development of porcine preimplantation embryos.

Theriogenology

March 2025

College of Veterinary Medicine and Research Institute for Veterinary Science, Seoul National University, Seoul, 08826, Republic of Korea. Electronic address:

To improve the efficiency of in-vitro-produced (IVP) porcine embryos, we focused on the events that usually occur during in-vivo embryonic transit from the oviduct to the uterus. Extracellular vesicles (EVs) are released by different mammalian cells and are imperative for intercellular communication and reflect the cell's physiological state. Based on these characteristics, EVs were isolated from oviductal and uterine fluid to imitate the in vivo environment and improve the efficiency of IVP embryos.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

Objective: Dysglycemia has deleterious outcomes on critically ill patients with diabetes mellitus (DM). Insulin degludec, an ultra-long-acting insulin, is associated with lower rates of hypoglycemia and blood glucose (BG) variability in non-critically ill patients. The experience with insulin degludec in the intensive care units is lacking.

Introduction: Saskatoon berries are grown in Canada and some northwestern states in the United States, and are notable for containing abundant antioxidant polyphenols, vitamins, metal elements, and fiber. To increase consumer interest in and accessibility to Saskatoon berries, some producers have begun to develop processes for refining Saskatoon berries into a powder with an extended shelf life that can be incorporated into a variety of value-added food products. To assess the desirability of this approach, this study sought to determine how the sensory attributes, consumer acceptability, and volatile and non-volatile composition of a plain, Greek-style frozen yogurt (PY) changed when fortified with 16% Saskatoon berry powder (SBP).

Corticosteroids reduce pathological angiogenesis yet compromise reparative vascular remodeling in a model of retinopathy.

Proc Natl Acad Sci U S A

December 2024

Departments of Ophthalmology, Maisonneuve-Rosemont Hospital Research Centre, University of Montreal, Montreal, QC H1T 2M4, Canada.

Tissue inflammation is often broadly associated with cellular damage, yet sterile inflammation also plays critical roles in beneficial tissue remodeling. In the central nervous system, this is observed through a predominantly innate immune response in retinal vascular diseases such as age-related macular degeneration, diabetic retinopathy, and retinopathy of prematurity. Here, we set out to elucidate the dynamics of the immune response during progression and regression of pathological neovascularization in retinopathy.

Article Synopsis
  • Hereditary myopathies involve several hundred genetic variants, with Limb-girdle muscular dystrophies (LGMDs) being a diverse group of disorders linked to more than 30 genes, characterized primarily by limb weakness.
  • The study analyzed 2,372 patients across 21 countries to assess the prevalence of LGMD and Pompe disease through next-generation sequencing (NGS), finding that 11% had pathogenic genetic variants, with a high diagnostic effectiveness for LGMD (86.2%).
  • The findings emphasize the importance of including specific genes in NGS panels for diagnosing LGMW, contributing to a better understanding of LGMD and aiding in the identification of late-onset Pompe disease.

Assessing the response to systemic therapy in neuroendocrine tumors (NET) is challenging since morphological imaging response is often delayed and not necessarily reflective of clinical benefit. Peptide receptor radionuclide therapy (PRRT) has a complex mechanism of action, further complicating response assessment. In response to these challenges, the European Neuroendocrine Tumor Society (ENETS) Theranostics Task Force conducted a statement-based survey among experts to identify the current landscape and unmet needs in PRRT response assessment.
