Experience-dependent plasticity of gustatory insular cortex circuits and taste preferences.

Early experience with food influences taste preference in adulthood. How gustatory experience influences development of taste preferences and refinement of cortical circuits has not been investigated. Here, we exposed weanling mice to an array of taste solutions and determined the effects on the preference for sweet in adulthood.

A Cluster of Five Deaths Due to Methanol Toxicity After Apparent Hand Sanitizer Ingestion in the Setting of Chronic Alcoholism.

Methanol toxicity and its associated pathologies have been widely studied, however, at the beginning of the COVID-19 pandemic, there was an increase in methanol toxicity due to apparent consumption of contaminated hand sanitizer. We report a cluster of five deaths and one presumed death due to the apparent consumption of hand sanitizer, contaminated with methanol, in the setting of chronic alcoholism. The deaths occurred in Coconino County, Arizona, over a four-and-a-half-month period (June-October 2020), before and during a Food and Drug Administration recall of contaminated hand sanitizer.

Two Single-Drug Fatal Intoxications by Mitragynine.

Mitragyna speciosa, a species of plant that is native to Thailand, Malaysia and Southeast Asia, contains two major psychoactive alkaloids: mitragynine and 7-hydroxymitragynine. Pharmacologically, the alkaloids exhibit biphasic effects-at low doses, stimulant effects are realized, while high doses exhibit sedative effects. For years, the plant has been used recreationally and medicinally for these effects, but its use has been implicated in and associated with intoxications and deaths.

Concrete Repair Durability.

The repairs of building structures are inevitable and indispensable. Repairs are used to restore or maintain the usability of existing facilities, often contributing to the extension of their expected service life, increasing the sustainability of building resources. Given that conservation rules are observed, repairs are also used to save monuments.

Implementation of a Nurse-Empowered Renal Anemia Protocol in Children.

A high proportion of patients on hemodialysis persist with low hemoglobin levels despite receiving treatment with erythropoiesis-stimulating agents. A registered nurse-driven renal anemia protocol was designed and implemented by a team in a pediatric hemodialysis unit. We compared proportion of patients achieving the target hemoglobin (Hgb) and transferrin saturation (TSAT) before and after the implementation of the protocol.
