Muscle Contractility in Hypokalemic Periodic Paralysis.

Introduction/aims: Primary hypokalemic periodic paralysis (HypoPP) can present with periodic paralysis and/or permanent muscle weakness. Permanent weakness is accompanied by fat replacement of the muscle. It is unknown whether the permanent muscle weakness is solely due to fat replacement or if other factors affect the ability of the remaining muscle fibers to contract.

Cryospray reduces pain during venous cannulation in elective surgery patients: a randomized placebo-controlled study.

Background: Venous cannulation is widely used in healthcare systems, and for many patients, it is painful and distressing. We hypothesized that the rapid onset of cryospray use would reduce pain from venous cannulation compared to the use of a placebo spray.

Methods: The trial was a prospective randomized placebo-controlled trial including 130 adult patients scheduled for elective surgery.

Targeted nanoliposomes to improve enzyme replacement therapy of Fabry disease.

The central nervous system represents a major target tissue for therapeutic approach of numerous lysosomal storage disorders. Fabry disease arises from the lack or dysfunction of the lysosomal alpha-galactosidase A (GLA) enzyme, resulting in substrate accumulation and multisystemic clinical manifestations. Current enzyme replacement therapies (ERTs) face limited effectiveness due to poor enzyme biodistribution in target tissues and inability to reach the brain.

An Alkyne-Containing Isoprenoid Analogue Based on a Farnesyl Diphosphate Scaffold Is a Biologically Functional Universal Probe for Proteomic Analysis.

Prenylation consists of the modification of proteins with either farnesyl diphosphate (FPP) or geranylgeranyl diphosphate (GGPP) at a cysteine near the C-terminus of target proteins to generate thioether-linked lipidated proteins. In recent work, metabolic labeling with alkyne-containing isoprenoid analogues including C15AlkOPP has been used to identify prenylated proteins and track their levels in different diseases. Here, a systematic study of the impact of isoprenoid length on proteins labeled with these probes was performed.
