Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Cumulative live birth rates in in-vitro fertilization

Minerva Ginecologica, 2019
Traditionally, in-vitro fertilization (IVF) success rates have been reported in terms of live birth per fresh cycle or embryo transfer. However, reporting IVF outcomes using cumulative live birth rates (LBR), defined as the first live birth following the use of all fresh and frozen embryos derived from a single ovarian stimulation cycle appears to be a

Cumulative Live Birth Rates After IVF in Patients With Polycystic Ovaries: Phenotype Matters

Reproductive BioMedicine Online, 2018
Do cumulative live birth rates (CLBR) vary among women with different polycystic ovary syndrome (PCOS) phenotypes who undergo IVF/intracytoplasmic sperm injection (ICSI) treatment?In this retrospective cohort study, data from 567 patients undergoing an assisted reproductive technology (ART) cycle between January 2010 and December 2015 were collected ...

Cumulative live-birth rates after assisted reproductive technology

Current Opinion in Obstetrics & Gynecology, 2010
Despite the promising success rates of IVF, many couples have to undergo several cycles before achieving live birth. In counseling patients faced with subfertility, it is important to provide cumulative live-birth rates. This review evaluates the current knowledge on cumulative rates, summarizing recently published evidence.Existing data have been ...
