Short term e-bicycle riding results in favorable cardiometabolic shifts in moderately active adults.

Purpose: Electric bikes (EB) are a form of active transportation with demonstrated health benefits. The purpose of this study was to determine the influence of riding an EB for one week on indices of cardiometabolic health in middle-aged adults.

Methods: Adults (n = 22; age = 57.

Characterisation of a cyclic peptide that binds to the RAS binding domain of phosphoinositide 3-kinase p110α.

P110α is a member of the phosphoinositide 3-kinase (PI3K) enzyme family that functions downstream of RAS. RAS proteins contribute to the activation of p110α by interacting directly with its RAS binding domain (RBD), resulting in the promotion of many cellular functions such as cell growth, proliferation and survival. Previous work from our lab has highlighted the importance of the p110α/RAS interaction in tumour initiation and growth.

Transitioning From High-dose Methadone to Buprenorphine Using a Microdosing Approach: Unique Considerations at ASAM Level 3 Facilities.

Transitions from high-dose methadone to buprenorphine for treatment of opioid use disorder (OUD) present risk of precipitated withdrawal related to the introduction of a high-affinity partial agonist at the mu-opioid receptor after occupancy by a lower-affinity full agonist. Various strategies have been explored to maintain patient stability during this process, including microdosing buprenorphine. Current literature lacks consensus on an optimal setting and strategy for initiating a buprenorphine microdosing protocol and gives little detail on patients' conditions after the acute transition period.

Development of a cell-free split-luciferase biochemical assay as a tool for screening for inhibitors of challenging protein-protein interaction targets.

Targeting the interaction of proteins with weak binding affinities or low solubility represents a particular challenge for drug screening. The NanoLuc ® Binary Technology (NanoBiT ®) was originally developed to detect protein-protein interactions in live mammalian cells. Here we report the successful translation of the NanoBit cellular assay into a biochemical, cell-free format using mammalian cell lysates.

Vitamin A and Wound Healing.

Vitamin A is a general term for retinoids. Vitamin A deficiency leads to a variety of cutaneous manifestations. It also functions as a hormone through retinoic acid receptors altering the activity of multiple cell lines.
