Two new isolates of bovine lentivirus, also known as bovine immunodeficiency-like virus (BIV), were obtained from a seropositive cattle herd in Florida. This is the first report of new isolates of BIV since the original BIV strain, R29, was isolated in 1969. The two new BIV isolates were derived from blood buffy coat cells cocultivated in vitro with fetal bovine lung cell cultures. The new isol...

BACKGROUND Partial protective efficacy lasting up to 43 months after vaccination with the RTS,S malaria vaccine has been reported in one cohort (C1) of a Phase IIb trial in Mozambique, but waning efficacy was observed in a smaller contemporaneous cohort (C2). We hypothesized that low dose exposure to asexual stage parasites resulting from partial pre-erythrocytic protection afforded by RTS,S ma...

Rosetting is a parasite adhesion phenotype associated with severe malaria in African children. Why parasites form rosettes is unknown, although enhanced invasion or immune evasion have been suggested as possible functions. Previous work showed that rosetting does not enhance parasite invasion under standard in vitro conditions. We hypothesised that rosetting might promote invasion in the presen...

Repurposing by-products to alternative applications has become a vital part of food research. Barley rootlets (BRs) are side-stream malting and brewing industries. This study focuses on processing BRs into ingredients, using fermentation with five lactic acid bacteria (LAB) as valorisation technique. The strains used were Lactiplantibacillus plantarum FST 1.7, Lactobacillus amylovorus FST2.11, ...

Lai et al. [Phys. Rev. E 62, R29 (2000)] claim that the angular velocity of the phase point moving along the chaotic trajectory in a properly chosen projection (the instantaneous frequency) is intermittent. Using the same examples, namely the Rössler and the Lorenz systems, we show the absence of intermittency in the dynamics of the instantaneous frequency. This is confirmed by demonstrating th...

Mycoplasma contamination of eukaryotic cell cultures is a common and widely recognised problem, estimated to affect 15–80% of all long term cell lines [1]. Infection with mycoplasmas can lead to a variety of effects such as impaired growth [2], chromosome abnormalities [3], enzyme inhibition [4], proteolytic degradation [5], B-lymphocyte proliferation [6], cytokine induction [7] and superantige...
