Marine mammals underwent a dramatic series of morphological transformations throughout their evolutionary history that facilitated their ecological transition to life in the water. Pinnipeds are a diverse clade of marine mammals that evolved from terrestrial carnivorans in the Oligocene (∼27 Ma). However, pinnipeds have secondarily lost the dental innovations emblematic of mammalian and carnivoran feeding, such as a talonid basin or shearing carnassials. Read More

Background: Poleroviruses, such as turnip yellows virus (TuYV), are plant viruses strictly transmitted by aphids in a persistent and circulative manner. Acquisition of either virus particles or plant material altered by virus infection is expected to induce gene expression deregulation in aphids which may ultimately alter their behavior.

Results: By conducting an RNA-Seq analysis on viruliferous aphids fed either on TuYV-infected plants or on an artificial medium containing purified virus particles, we identified several hundreds of genes deregulated in Myzus persicae, despite non-replication of the virus in the vector. Read More

Intestinal microbiota significantly influences the intake, storage, and utilization of body nutrients, as well as animal growth and development. The establishment of microbiota is affected by many factors, such as delivery and feeding modes, antibiotics, disease, and the surrounding environment. In this study, we selected Chinese indigenous Mashen and Jinfen White pigs as the study subjects. Read More

To increase the availability and expand the raw material base, the production of polyhydroxyalkanoates (PHA) by the wild strain B-10646 on hydrolysates of sugar beet molasses was studied. The hydrolysis of molasses was carried out using -fructofuranosidase, which provides a high conversion of sucrose (88.9%) to hexoses. Read More

Lumpy skin disease (LSD) is a transboundary viral disease of cattle and buffaloes transmitted by blood-feeding vectors and causes high morbidity and low-to-moderate mortality. Since the first observation of LSD in Zambia in 1929, it has spread in cattle populations across African countries, the Middle East, Europe, and Asia. Following the recent outbreaks of LSD in South Asian countries such as India and Bangladesh, the disease was first reported in cattle farms in Nepal in June 2020. Read More
