Distinguishing Doors and Floors on All Fours: Landmarks as Tools for Vertical Navigation Learning in Domestic Dogs ().

Spatial navigation allows animals to understand their environment position and is crucial to survival. An animal's primary mode of spatial navigation (horizontal or vertical) is dependent on how they naturally move in space. Observations of the domestic dog () have shown that they, like other terrestrial animals, navigate poorly in vertical space.

Shake It Off: Investigating the Function of a Domestic Dog Behavior in Social Contexts.

Shaking in domestic dogs-a rapid side-to-side movement of the body or head-is a commonly observed behavior, yet its function remains minimally researched. The present study aimed to investigate the use of shaking behavior in naturalistic social contexts, with the hypothesis that shaking functions as a marker of transition between behaviors or activities. In addition, as the prior literature has suggested that shaking more frequently occurred in postures or conditions of stress, either to signal stress or to mitigate it, we looked at postures related to affect before and after shaking.

The HLA-B -21 M/T dimorphism associates with disease severity in COVID-19.

Host genetics shape immune responses and influence severity of infectious diseases. The HLA-B -21 M/T dimorphism tunes the functionality of natural killer (NK) cells expressing the inhibitory receptor NKG2A. NKG2A NK cells have been reported to recognize SARS-CoV-2-infected cells, but it remains unclear whether the HLA-B -21 M/T dimorphism associates with COVID-19 severity.

End-To-End Automated Intact Protein Mass Spectrometry for High-Throughput Screening and Characterization of Bispecific and Multispecific Antibodies.

Bispecific antibodies (bsAbs) and multispecific antibodies (msAbs) represent a promising frontier in therapeutic antibody development, offering unique capabilities not achievable with traditional monoclonal antibodies. Despite their potential, significant challenges remain due to their increased molecular complexity. One prominent challenge is the correct assembly of light and heavy chains, as improper pairing leads to mispaired or incompletely assembled species that lack therapeutic efficacy and possess undesired properties, impairing the developability, manufacturability, and safety.
