Basic Science and Pathogenesis.

Background: Changes in neuroinflammatory tone have been shown to modulate neuroimmune responses to Alzheimer's disease (AD) pathology and shape disease outcomes, however, extrinsic factors that modify neuroimmune activation remain poorly understood. The gut microbiome is one such factor, with the ability to shape peripheral and central immune activation, as well as AD pathologies. AD patients display unique changes in microbiome composition, however, the link between specific AD-associated gut bacteria, neuroinflammatory tone, and AD outcomes remains to be elucidated.

Coefficients in Taylor's law increase with the time scale of water clarity measurements in a global suite of lakes.

Identifying the scaling rules describing ecological patterns across time and space is a central challenge in ecology. Taylor's law of fluctuation scaling, which states that the variance of a population's size or density is proportional to a positive power of the mean size or density, has been widely observed in population dynamics and characterizes variability in multiple scientific domains. However, it is unclear if this phenomenon accurately describes ecological patterns across many orders of magnitude in time, and therefore links otherwise disparate observations.

Comparative Outcomes of a Cognitive-Behavioral Skills Building Program on the Mental Health and Healthy Behaviors of Prenursing Students.

Background: Nursing students experience significantly more stress related diseases when compared to non-nursing students, and the state of their mental health can result in short-term increased attrition rates and increased nursing shortages.

Purpose: A preexperimental pre-post study design was used to examine mental health and healthy behaviors among prenursing students.

Methods: Cohorts received the MINDSTRONG© program either in-person or virtually.

Splenic fibroblasts control marginal zone B cell movement and function via two distinct Notch2-dependent regulatory programs.

Innate-like splenic marginal zone (MZ) B (MZB) cells play unique roles in immunity due to their rapid responsiveness to blood-borne microbes. How MZB cells integrate cell-extrinsic and -intrinsic processes to achieve accelerated responsiveness is unclear. We found that Delta-like1 (Dll1) Notch ligands in splenic fibroblasts regulated MZB cell pool size, migration, and function.

Genetic interaction analysis of transcription factors and in the regulation of respiration and fluconazole susceptibility.

is the second most common cause of invasive candidiasis and is widely known to have reduced susceptibility to fluconazole relative to many other spp. Upc2A is a transcription factor that regulates ergosterol biosynthesis gene expression under conditions of sterol stress such as azole drug treatment or hypoxia. Through an microevolution experiment, we found that loss-of-function mutants of the ATF/CREB transcription factor suppresses the fluconazole hyper-susceptibility of the ∆ mutant.
