Structural basis of RND-type multidrug exporters [PDF]
Frontiers in Microbiology, 2015 Bacterial multidrug exporters are intrinsic membrane transporters that act as cellular self-defense mechanism. The most notable characteristics of multidrug exporters is that they export a wide range of drugs and toxic compounds. The overexpression of these exporters causes multidrug resistance.

The GTPase-deficient Rnd Proteins Are Stabilized by Their Effectors [PDF]
Journal of Biological Chemistry, 2012 Rnd proteins are Rho family GTP-binding proteins with cellular functions that antagonize RhoA signaling. We recently described a new Rnd3 effector Syx, also named PLEKHG5, that interacts with Rnds via a Raf1-like "Ras-binding domain." Syx is a multidomain RhoGEF that participates in early zebrafish development. Here we demonstrated that Rnd1, Rnd2, and

On the RND under Heston's Stochastic Volatility Model [PDF]
SSRN Electronic Journal, 2021 We consider Heston's (1993) stochastic volatility model for valuation of European options to which (semi) closed form solutions are available and are given in terms of characteristic functions. We prove that the class of scale-parameter distributions with mean being the forward spot price satisfies Heston's solution.

Tripartite assembly of RND multidrug efflux pumps [PDF]
Nature Communications, 2016 Abstract Tripartite multidrug efflux systems of Gram-negative bacteria are composed of an inner membrane transporter, an outer membrane channel and a periplasmic adaptor protein. They are assumed to form ducts inside the periplasm facilitating drug exit across the outer membrane. Here we present the reconstitution

The Experience of a Tertiary Reference Hospital in the Study of Rare Neurological Diseases
Medicina, 2023 Background and Objectives: Rare diseases (RDs) are life-threatening or chronically impairing conditions that affect about 6% of the world’s population. RDs are often called ‘orphan’ diseases, since people suffering from them attract little support from ...

Scientific Reports, 2022 Tripartite resistance-nodulation-division (RND) efflux pumps, such as AcrAB-TolC of Salmonella Typhimurium, contribute to antibiotic resistance and comprise an inner membrane RND-transporter, an outer membrane factor, and a periplasmic adaptor protein ...
