Human fertility at a crossroad

Reproductive BioMedicine Online
Since the early 1970s, family planning policies aiming to reduce global population growth have been successful. Currently, more than 50% of all countries are (way) below the replacement level of 2.1 child per woman. Underpopulation causes distinct society challenges in many countries.

A novel isolator-based system promotes viability of human embryos during laboratory processing

, 2012
In vitro fertilisation (IVF) and related technologies are arguably the most challenging of all cell culture applications. The starting material is a single cell from which one aims to produce an embryo capable of establishing a pregnancy eventually ...

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Agrotechnical Biofortification as a Method to Increase Selenium Content in Spring Wheat

Agronomy, 2021
Selenium (Se) is a micronutrient that is insufficiently present in the human diet. Increasing its content in food through appropriately matched agricultural practices may contribute to reducing Se deficit in humans. The study covered the effect of grain,

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
