Neutralization of SARS-CoV-2 (lineage B.1.1) by hyperimmune llama (Lama glama) serum in vero cell culture.

Objective.: To evaluate the serological antibody response of a llama (Lama glama) to SARS-CoV-2 (B.1.

Quantification of smooth pursuit dysfunction in multiple sclerosis.

Background: Smooth pursuit dysfunction is common in MS, but rarely quantified and may be missed on exam.

Methods: NeuroFitONE™ smooth pursuit performance measures were compared between MS (n = 20) and healthy control (n = 19) participants.

Results: Compared to controls, MS patients had lower proportion of smooth pursuit (0.

Peptides derived from plasma proteins released by bothropasin, a metalloprotease present in the Bothrops jararaca venom.

Viperid snake venoms contain proteases that affect hemostasis by degrading important proteins such as those that participate in the coagulation cascade. The Bothrops jararaca venom presents as its main components metallo and serine proteases, which comprise around 65% of the venom composition. Bothropasin is a hemorrhagic metalloprotease from the B.

[Rapid centrifugation assay standarization for dengue virus isolation].

The plate centrifugation assay was standardized for dengue virus isolation from serum samples. C6/36-HT cells were used determining the optimal values for centrifugation spin speed, inoculum, sera dilution, and incubation time. Then, 22 positive serum samples with viral isolation and viral strains of the four reference dengue virus serotypes were tested simultaneously by the standardized plate centrifugation method and the conventional tube culture.
