Impact of various detergent-based immersion and perfusion decellularization strategies on the novel caprine pancreas derived extracellular matrix scaffold

Frontiers in Bioengineering and Biotechnology, 2023
Limited availability of the organs donors has facilitated the establishment of xenogeneic organ sources for transplantation. Numerous studies have decellularized several organs and assessed their implantability in order to provide such organs.

Regular holonomic D[[h]]-modules

, 2009
We describe the category of regular holonomic modules over the ring D[[h]] of linear differential operators with a formal parameter h. In particular, we establish the Riemann-Hilbert correspondence and discuss the additional t-structure related to h ...

Differential resistance to cell entry by porcine endogenous retrovirus subgroup A in rodent species [PDF]

, 2007
Background The risk of zoonotic infection by porcine endogenous retroviruses (PERV) has been highlighted in the context of pig-to-human xenotransplantation. The use of receptors for cell entry often determines the host range of retroviruses.

Establishment of a donor pig for xenotransplantation clinical trials based on the principle of Changsha Communiqué

Health Care Science, 2023
Background Xenotransplantation is a potential way to reduce the shortage of the needed organ grafts for the end‐stage disease. Immune rejection, physiological incompatibility and bio‐safety are the most critical issues.

Range convergence monotonicity for vector measures and range monotonicity of the mass

, 2019
We prove that the range of sequence of vector measures converging widely satisfies a weak lower semicontinuity property, that the convergence of the range implies the strict convergence (convergence of the total variation) and that the strict convergence

Glutamine Deprivation Triggers Tribbles Homolog 3 Dependent G‐Quadruplex Resolution to Maintain DNA Repair and Tumor Survival

Advanced Science, EarlyView.
Glutamine deprivation triggers transient DNA damage yet activates adaptive repair in hepatocellular carcinoma cells. We identify TRIB3 as a stress‐induced nuclear scaffold that associates with DDX5 and G‐quadruplex DNA atBRCA1 andRAD51AP1 promoters. TRIB3 loss increases G4 accumulation, suppresses HR gene transcription, elevates γ‐H2A.X, and sensitizes

An association between type A porcine endogenous retrovirus copy number and hematological parameters and gender in miniature pigs

Вавиловский журнал генетики и селекции, 2017
Pig is the most promising species for transplantation of organs and cells into humans, although implementation of xenotransplantation in clinical practice has been hindered by the risk of infecting the recipient with zoonotic infectious diseases. Porcine

How to Detect Porcine Endogenous Retrovirus (PERV) Infections in Patients After Transplantation of Pig Organs. [PDF]

Xenotransplantation
Porcine endogenous retroviruses (PERVs) are integrated into the genome of all pigs and can infect human cells in culture. However, no PERV infections have been reported in recipients following preclinical or clinical xenotransplantation or deliberate ...

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

Ecography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

The infectivity and host range of the ecotropic porcine endogenous retrovirus, PERV-C, is modulated by residues in the C-terminal region of its surface envelope protein

Virology, 2006
Endogenous retroviral genetic material serves as a reservoir for the generation of retroviral pathogens by recombination between activated endogenous or exogenous infectious agents. Some porcine tissues actively express infectious porcine endogenous retroviruses (PERVs). Of the three classes of PERV characterized to date, two, PERV-A and B, are capable
