Using a real-time ABCDEF compliance tool to understand the role of bundle elements in mortality and delirium.

Background: ABC-123, a novel Epic electronic medical record real-time score, assigns 0 to 3 points per bundle element to assess ABCDEF bundle compliance. We sought to determine if maximum daily ABC-123 score (ABC-MAX), individual bundle elements, and mobility were associated with mortality and delirium-free/coma-free intensive care unit (DF/CF-ICU) days in critically injured patients.

Methods: We reviewed 6 months of single-center data (demographics, Injury Severity Score [ISS], Abbreviated Injury Scale of the head [AIS-Head] score, ventilator and restraint use, Richmond Agitation Sedation Score, Confusion Assessment Method for the ICU, ABC-MAX, ABC-123 subscores, and mobility level).

L-arginine via nitric oxide is an inhibitory feedback modulator of Aplysia feeding.

An increase in L-arginine hemolymph concentration acts as a postingestion signal inhibiting Aplysia feeding. At physiological concentrations (a 10-μM increase over background), the inhibitory effect of L-arginine is too weak to block feeding in hungry animals. However, a 10-μM increase in L-arginine concentration acts along with another inhibitory stimulus, the sustained presence of food odor, to inhibit feeding after a period of access to food.

Analysis of the Aspergillus nidulans thaumatin-like cetA gene and evidence for transcriptional repression of pyr4 expression in the cetA-disrupted strain.

The asexual spore or conidium plays a critical role in the life cycle of many filamentous fungi. However, the process of conidial germination remains surprisingly obscure. To better understand this process at the molecular level we characterized the Aspergillus nidulans cetA gene which is uniquely transcribed in conidiating cultures and whose transcript is significantly enriched in mature conidia.

Genomic approach to identification of mutations affecting caspofungin susceptibility in Saccharomyces cerevisiae.

The antifungal agent caspofungin (CAS) specifically interferes with glucan synthesis and cell wall formation. To further study the cellular processes affected by CAS, we analyzed a Saccharomyces cerevisiae mutant collection (4,787 individual knockout mutations) to identify new genes affecting susceptibility to the drug. This collection was screened for increased CAS sensitivity (CAS-IS) or increased CAS resistance (CAS-IR).

Multiple memory processes following training that a food is inedible in Aplysia.

In many organisms, memory after training can be separated into a number of processes. We now report that separable memory processes are also initiated by a training procedure affecting Aplysia feeding behavior, a model system for examining the neural mechanisms underlying the regulation of a complex behavior. Four distinct memory process were identified: (1) a very short-term memory that declines within 15 min, (2) a short-term memory that persists for 0.
