A Systematic Review And Meta-Analysis Of Resting-State Fmri In Anxiety Disorders: Need For Data Sharing To Move The Field Forward, André Zugman, Laura Jett, Chase Antonacci, Anderson M. Winkler, Daniel Samuel Pine

School of Medicine Publications

Highlights

• There are numerous studies investigating rs-fMRI and anxiety; however, the methodologies are inconsistent.

• Anxiety patients show hypoconnectivity between the amygdala and the medial prefrontal cortex.

• This finding is not robust against possible publication bias. Thus, no strong findings manifest in available literature.

• More studies are needed with standardized methods and larger sample sizes.

Abstract

Anxiety disorders are among the most prevalent psychiatric disorders. Neuroimaging findings remain uncertain, and resting state functional magnetic resonance (rs-fMRI) connectivity is of particular interest since it is a scalable functional imaging modality. Given heterogeneous past findings for rs-fMRI in anxious individuals, we characterize patterns …

Sex And Stress Modulate Pupal Defense Response In Tobacco Hornworm, Sukhman Singh, Sakshi Watts, Ishveen Kaur, Isabella Rodriguez, Jessica Ayala, Dariela Rodriguez, Elian Martin, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

In insects, larval and adult defenses against predators have been well studied. However, pupal (also known as resting stage) defenses have been overlooked and not examined thoroughly. Although some pupa possess antipredator strategies such as hairs, spines, cryptic coloration, and exudation of chemicals, few studies have tested these responses and the factors affecting them. Here, we investigated the behavioral responses in tobacco hornworm Manduca sexta that pupates in soil by introducing an external stimulus using vibrations from an electric toothbrush to mimic predation. We observed that M. sexta made violent wriggling (twitching), followed by pulsating movements in response to the …

Precise Method To Identify Kinase Drug Targets In Complex Diseases: The First Step Towards Sustainable And Effective Treatment, Hasbanny Irisson, Marzieh Ayati

Research Symposium

Background: Kinases are enzymes that have proven to be important drug targets due to their role in critical biological mechanisms such as phosphorylation. Phosphorylation happens when a kinase catalyzes the transfer of a phosphate group to a protein in a phosphorylated site, which then becomes known as the substrate of the kinase. Any dysregulation of protein phosphorylation causes a wide range of complex diseases including cancer. Thus, discovering the links between kinases and their substrates (i.e. predicting kinase-substrate associations (KSAs)) is crucial in developing effective and sustainable treatments. Presently, less than 5% of phosphorylated sites have an associated kinase, and …
