Recent innovations in extended in vitro culture (IVC) systems have revolutionized our understanding of human peri-implantation development. Building on foundational animal studies, refined protocols now support human embryo culture beyond the blastocyst stage, providing unprecedented access to previously elusive developmental events. These systems have yielded critical insights into early morphogenetic processes, lineage specification, and tissue organization, significantly advancing developmental biology. Here, we provide our current protocol for the extended culture of human embryos, followed by immunofluorescence for lineage markers of interest. Unveiling human peri-implantation development also promises to improve reproductive medicine, potentially addressing challenges related to implantation failure, chromosomal instability in embryos, as well as congenital disorders. Insights gained from this research may pave way for novel therapeutic approaches and advancements in medically assisted reproduction.

Simulations in three dimensions and time provide guidance on implantable, electroenzymatic glutamate sensor design; relative placement in planar sensor arrays; feasibility of sensing synaptic release events; and interpretation of sensor data. Electroenzymatic sensors based on the immobilization of oxidases on microelectrodes have proven valuable for the monitoring of neurotransmitter signaling in deep brain structures; however, the complex extracellular milieu featuring slow diffusive mass transport makes rational sensor design and data interpretation challenging. Simulations show that miniaturization of the disk-shaped device size below a radius of ∼25 μm improves sensitivity, spatial resolution, and the accuracy of glutamate concentration measurements based on calibration factors determined .

The study explored HSPiP and QbD-(quality by design) enabled optimized cubosomes for sustained drug release, improved permeation, and enhanced oral bioavailability. OCUB1 (the optimized product) was characterized for size, zeta potential (ZP), thermal analysis, and surface roughness. drug release and hemolysis studies were carried out using a dialysis membrane and rat erythrocytes (4 % suspension), respectively.

Severe scarring is an inevitable consequence of large full-thickness skin wounds, often leading to long-term complications that affect patients' well-being and necessitate extended medical interventions. While autologous split-thickness skin grafts remain the clinical standard for wound treatment, they frequently result in contractures, excessive scarring, and the need for additional corrective procedures. To address these challenges, bioengineered skin substitutes capable of promoting efficient healing while reducing complications are highly desirable.

Patients with multiple myeloma develop resistance to thalidomide during therapy, and the mechanisms to counteract thalidomide resistance remain elusive. Here, we explored the interaction between cereblon and mitochondrial function to mitigate thalidomide resistance in multiple myeloma. Measurements of cell viability, ATP production, mitochondrial membrane potential, mitochondrial ROS, and protein expression via western blotting were conducted in vitro using KSM20 and KMS26 cells to assess the impact of thalidomide on multiple myeloma.

The pre-dimerization of endosome-localized RNA sensor Toll-like receptor 3 (TLR3) is required for its innate recognition, yet how TLR3 pre-dimers are formed and precisely primed for innate activation remains unclear. Here, we demonstrate that endosome-localized self RNA Rmrp directly binds to TLR3 and induces TLR3 dimerization in the early endosome but does not interact with endosome-localized TLR7, TLR8, TLR9 or cytoplasmic RNA sensor RIG-I under homeostatic conditions. Cryo-EM structure of Rmrp-TLR3 complex reveals a novel lapped conformation of TLR3 dimer engaged by Rmrp, which is distinct from the activation mechanism by dsRNA and the specific structural feature at the 3'-end of Rmrp is critical for its functional interaction with TLR3.
