Intellectual Ventures Global Good Fund, Bellevue, WA 98007.

To help address the limitations of operating conventional microbiological culture incubators in low resource environments, a new incubator design was developed and tested to meet the requirements of operation in laboratories without reliable power (power outages up to 12 contiguous hours) or climate control (ambient indoor temperatures from 5 °C to 45 °C). The device is designed to enable adherence to incubation temperatures recommended for growth detection, identification, and drug susceptibility testing (DST) of human pathogenic bacteria. During power outages, stable temperatures are maintained in the device's internal sample compartment by employing phase change material (PCM) as a bi-directional thermal battery to maintain incubation temperature.

The Role of R-Ras Proteins in Normal and Pathologic Migration and Morphologic Change.

Am J Pathol 2021 Jun 7. Epub 2021 Jun 7.

Department of Pathology and Laboratory Medicine, Medical University of South Carolina, Charleston, SC 29425-9080. Electronic address:

The contributions that the R-Ras subfamily (R-Ras, R-Ras2/TC21 and M-Ras) of small GTP-binding proteins make to normal and aberrant cellular functions have historically been poorly understood. However, this has begun to change with the realization that all three R-Ras subfamily members are occasionally mutated in Noonan syndrome, a RASopathy characterized by the development of hematopoietic neoplasms and abnormalities affecting the immune, cardiovascular and nervous systems. Consistent with the abnormalities seen in Noonan syndrome, a host of new studies have implicated R-Ras proteins in physiologic and pathologic changes in cellular morphology, adhesion, and migration in the cardiovascular, immune, and nervous systems.

Normal cognitive test scores cannot be interpreted as accurate measures of ability in the context of failed performance validity testing: A symptom- and detection-coached simulation study.

J Clin Exp Neuropsychol 2021 May 16:1-9. Epub 2021 May 16.

Department of Psychiatry & Behavioral Sciences, University of Kansas School of Medicine - Wichita, Wichita, KS, USA.

While use of performance validity tests (PVTs) has become a standard of practice in neuropsychology, there are differing opinions regarding whether to interpret cognitive test data when standard scores fall within normal limits despite PVTs being failed. This study is the first to empirically determine whether normal cognitive test scores underrepresent functioning when PVTs are failed. Participants, randomly assigned to either a simulated malingering group ( = 50) instructed to mildly suppress test performances or a best-effort/control group ( = 50), completed neuropsychological tests which included the North American Adult Reading Test (NAART), California Verbal Learning Test - 2 Edition (CVLT-II), and Test of Memory Malingering (TOMM).
