Upright BPPV Protocol: Feasibility of a New Diagnostic Paradigm for Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo Compared to Standard Diagnostic Maneuvers.

Front Neurol 2020 19;11:578305. Epub 2020 Nov 19.

Vestibology and ENT Unit, Giovanni Paolo II Hospital, Matera, Italy.

The diagnosis of benign paroxysmal positional vertigo (BPPV) involving the lateral semicircular canal (LSC) is traditionally entrusted to the supine head roll test, also known as supine head yaw test (SHYT), which usually allows identification of the pathologic side and BPPV form (geotropic vs. apogeotropic). Nevertheless, SHYT may not always allow easy detection of the affected canal, resulting in similar responses on both sides and intense autonomic symptoms in patients with recent onset of vertigo.

Mutational landscape of K-Ras substitutions at 12th position-a systematic molecular dynamics approach.

J Biomol Struct Dyn 2020 Oct 9:1-15. Epub 2020 Oct 9.

Department of Biomedical Sciences, College of Health and Sciences, Qatar University, Doha, Qatar.

K-Ras is a small GTPase and acts as a molecular switch by recruiting GEFs and GAPs, and alternates between the inert GDP-bound and the dynamic GTP-bound forms. The amino acid at position 12 of K-Ras is a hot spot for oncogenic mutations (G12A, G12C, G12D, G12R, G12S, and G12V), disturbing the active fold of the protein, leading to cancer development. This study aimed to investigate the potential conformational changes induced by these oncogenic mutations at the 12 position, impairing GAP-mediated GTP hydrolysis. Read More

High sensitivity, levitated microsphere apparatus for short-distance force measurements.

Rev Sci Instrum 2020 Aug;91(8):083201

Department of Physics, Stanford University, Stanford, California 94305, USA.

A high sensitivity force sensor based on dielectric microspheres in vacuum, optically trapped by a single, upward-propagating laser beam, is described. Off-axis parabolic mirrors are used both to focus the 1064 nm trapping beam and to recollimate it to provide information on the horizontal position of the microsphere. The vertical degree of freedom is readout by forming an interferometer between the light retroreflected by the microsphere and a reference beam, hence eliminating the need for auxiliary beams.
