O-23 HEPATITIS B VIRUS STATUS OF ORGAN DONORS IN ARGENTINA

Annals of Hepatology, 2023
Introduction and Objectives: Argentina is considered an area with a low prevalence of hepatitis B virus (HBV). However, the real prevalence of the disease is unknown. We aimed to study the prevalence of HBV in potential cadaveric donors.

HtrA4 is up-regulated during trophoblast syncytialization and BeWo cells fail to syncytialize without HtrA4

Scientific Reports, 2021
The outer layer of the human placenta comprises syncytiotrophoblast, which forms through fusion of cytotrophoblasts (syncytialization), and plays a critical role in maternal–fetal communication including nutrient/oxygen transportation and hormone ...

O-12 CHARACTERIZATION AND UTILIZATION OF HCV-POSITIVE DONORS IN ARGENTINA

Annals of Hepatology, 2023
Introduction and Objectives: Increased utilization of hepatitis C virus (HCV)-positive organ donors has been endorsed as one of several ways to combat organ shortages. However, HCV-positive donors remain poorly characterized. This study aimed to evaluate

Calculation of the substitutional fraction of ion-implanted He in an Fe target

, 2010
Ion-implantation is a useful technique to study irradiation damage in nuclear materials. To study He effects in nuclear fusion conditions, He is co-implanted with damage ions to reproduce the correct He/dpa ratios in the desired or available depth range.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Embryo Implantation

Developmental Biology, 2000
A lesson learned from modern developmental biology is the striking degree of conservation of strategies and molecules used to program developmental events in species as diverse as insects, birds, amphibians, and mammals. Nonetheless, mammals retain distinctions with regard to the strategies used to protect and nourish their offspring during development,

Spin properties of dense near-surface ensembles of nitrogen-vacancy centres in diamond [PDF]

, 2018
We present a study of the spin properties of dense layers of near-surface nitrogen-vacancy (NV) centres in diamond created by nitrogen ion implantation.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Association of antimüllerian hormone with polycystic ovarian syndrome phenotypes and pregnancy outcomes of in vitro fertilization cycles with fresh embryo transfer

BMC Pregnancy and Childbirth, 2022
Objective The current study was undertaken to investigate the relationship between antimüllerian hormone (AMH) and polycystic ovarian syndrome (PCOS) phenotypes and to determine whether AMH is associated with pregnancy outcomes in infertile women ...
