Summands of theta divisors on Jacobians [PDF]

open access: yes, 2019
We show that the only summands of theta divisors on Jacobians of curves and on intermediate Jacobians of cubic threefolds are the obvious powers of the curve and the Fano surface of lines on the threefold.

A Comprehensive Strategy for Screening for Xenotransplantation-Relevant Viruses in a Second Isolated Population of Göttingen Minipigs

open access: yesViruses, 2019
Xenotransplantation using pig tissues and organs is under development in order to alleviate the increasing shortage of human transplants. Since xenotransplantation may be associated with the transmission of porcine microorganisms to the human recipient ...

Microemulsion breakdown by pervaporation technique: Effect of the alkyl chain length of n-alkanol, a cosurfactant of the microemulsion [PDF]

open access: yes, 2007
Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol.

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

open access: yesВавиловский 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

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

open access: yesAdvanced 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

Gopakumar-Vafa invariants via vanishing cycles [PDF]

open access: yes, 2018
In this paper, we propose an ansatz for defining Gopakumar-Vafa invariants of Calabi-Yau threefolds, using perverse sheaves of vanishing cycles. Our proposal is a modification of a recent approach of Kiem-Li, which is itself based on earlier ideas of ...

Cross-species transmission of PERV appears unlikely [PDF]

open access: yesLiver Transplantation, 2000
Abstract Pig organs may offer a solution to the shortage of humandonor organs for transplantation, but concerns remain about possible cross-species transmission of porcine endogenousretrovirus (PERV). Samples were collected from 160 patients who had been treated with various living pig tissues up to 12 years earlier.

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

open access: yesEcography, 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.

Porcine Endogenous Retroviruses: Quantification of the Viral Copy Number for the Four Miniature Pig Breeds in China

open access: yesFrontiers in Microbiology, 2022
Domestic pigs has served not only as one of the most important economy livestock but also as ideal organ-source animals owing to similarity in anatomy, physiology, and organ size to humans.

Xenotransplantation: Perspectives and limits [PDF]

open access: yes, 2001
Xenotransplantation faces the dilemma of an unlimited supply of cells, tissues and organs on the one hand and severe obstacles and limits on the other. One reason for the limitations is that the source animal of choice, the pig, and the human recipient ...
