Monitoring Older Adult Blood Pressure Trends at Home as a Proxy for Brain Health.

Even when older adults monitor hypertension at home, it is difficult to understand trends and share them with their providers. MyHealthNetwork is a dashboard designed for patients and providers to monitor blood pressure readings to detect hypertension and ultimately warning signs of changes in brain health. A multidisciplinary group in a Digital Health course at Tufts University School of Medicine used Design Thinking to formulate a digital solution to promote brain health among older adults in the United States (US).

Does reducing light exposure decrease the incidence of retinopathy of prematurity in premature infants?

Background: Retinopathy of prematurity (ROP) can result in significant morbidity in preterm infants. Light exposure has been suggested to be a contributing factor.

Objective: A systematic review was performed to determine whether reducing light exposure in the neonatal intensive care unit decreased the incidence of ROP in preterm infants.

A screen for downstream effectors of Neurogenin2 in the embryonic neocortex.

Neurogenin (Ngn) 1 and Ngn2 encode basic-helix-loop-helix transcription factors expressed in the developing neocortex. Like other proneural genes, Ngns participate in the specification of neural fates and neuronal identities, but downstream effectors remain poorly defined. We set out to identify Ngn2 effectors in the cortex using a subtractive hybridization screen and identified several regionally expressed genes that were misregulated in Ngn2 and Ngn1;Ngn2 mutants.

Proteomic characterization of protein phosphatase complexes of the mammalian nucleus.

Our knowledge of the serine/threonine protein phosphatases of the mammalian nucleus is limited compared with their cytosolic counterparts. Microcystin-Sepharose chromatography and mass spectrometry were utilized to affinity purify and identify protein phosphatase-associated proteins from isolated rat liver nuclei. Far Western analysis with labeled protein phosphatase 1 (PP1) showed that many more PP1 binding proteins exist in the nucleus than were previously demonstrated.

The effects of continuous versus partial reinforcement schedules on associative learning, memory and extinction in Lymnaea stagnalis.

A continuous schedule of reinforcement (CR) in an operant conditioning procedure results in the acquisition of associative learning and the formation of long-term memory. A 50 % partial reinforcement (PR) schedule does not result in learning. The sequence of PR-CR training has different and significant effects on memory retention and resistance to extinction.
