Reprogramming of mesenchymal stem cells and adult fibroblasts following nuclear transfer in rabbits [PDF]

, 2009
The main aim of this thesis was to find out which donor cells would be most suitable for production of cloned rabbits with a targeted modification of their genome, and their corresponding patterns of reprogramming hetero- and euchromatic histone ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

The Male Primary Sex Ratio Bias in Goose Eggs Early in the Laying Season: A Pilot Study

Poultry
In bird eggs, the theoretical expectation of a primary sex ratio (at conception) of 50:50 males/females often fails to materialize. Using PCR technology for sex verification in this pilot study, we evaluated the primary sex ratio of 128 fertilized ...

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 ...

Research progress on novel bionic cryoprotectants in gamete and embryo cryopreservation

Frontiers in Veterinary Science
Cryopreservation technology has become a primary method for preserving animal genetic resources in the biomedical field. It achieves long-term storage by placing gametes or embryos in an ultra-low-temperature environment, enabling them to retain ...

Malaysia needs stricter regulation of the genetic testing of embryos

, 2023
DOWN syndrome is the most common genetic abnormality in newborns, and it is caused by the presence of an additional chromosome 21. As World Down Syndrome day approaches on March 21, we are reminded of the sobering statistic that around 90% of Down ...

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Survival of embryos of pejerrey Odontesthes bonariensis and Odontesthes humensis at different concentration of salinity [PDF]

Biotemas, 2009
Embryos of Odontesthes bonariensis and Odontesthes humensis were submitted to saline concentrations of 0, 5, 10, 20 and 30g.L-1. The control of mortality was made daily between the 8th and 12th days of incubation, at the which time the embryos had ...
