Nasal Glucagon Is Easier to Use and More Preferred and Needs Less Effort to Administer Than Injectable Glucagon: User Perceptions of Glucagon Administration During Severe Hypoglycemia Simulation.

Objective: To evaluate ease of use, user preference, and effort required to use nasal glucagon (NG) versus injectable glucagon needing reconstitution (IG) in simulations of severe hypoglycemia (SH)-a challenge for caregivers of a person with diabetes (PWD) in real-life.

Methods: In this randomized, crossover study, high-fidelity manikins placed in mock representative high-stress environments were used to simulate an SH rescue. Thirty-two trained (by PWDs) and 33 untrained participants attempted NG and IG administrations and then completed questionnaires regarding ease of use, preference, and workload for each device.

ZFAND1 Recruits p97 and the 26S Proteasome to Promote the Clearance of Arsenite-Induced Stress Granules.

Stress granules (SGs) are cytoplasmic assemblies of mRNPs stalled in translation initiation. They are induced by various stress conditions, including exposure to the environmental toxin and carcinogen arsenic. While perturbed SG turnover is linked to the pathogenesis of neurodegenerative diseases, the molecular mechanisms underlying SG formation and turnover are still poorly understood.

Roles of Hsp104 and trehalose in solubilisation of mutant huntingtin in heat shocked Saccharomyces cerevisiae cells.

Inhibition of huntingtin aggregation, either in the nucleus and/or in the cytosol, has been identified as a major strategy to ameliorate the symptoms of Huntington's disease. Chaperones and other protein stabilisers would thus be key players in ensuring the correct folding of the amyloidogenic protein and its expression in the soluble form. By transient activation of the global heat stress response in Saccharomyces cerevisiaeBY4742, we show that heterologous expression of mutant huntingtin (103Q-htt) could be modulated so that the protein was partitioned off in the soluble fraction of the cytosol.
