Development And Validation Of An Ultrahigh-Performance Liquid Chromatography–Tandem Mass Spectrometry Method To Investigate The Plasma Pharmacokinetics Of A KCa2.2/KCa2.3 Positive Allosteric Modulator In Mice, Mohammad Asikur Rahman, Devaraj Venkatapura Chandrashekar, Young-Woo Nam, Basir Syed, David Salehi, Hamidreza Montazeri Aliabadi, Miao Zhang, Reza Mehvar

Pharmacy Faculty Articles and Research

Rationale

There is currently no treatment for spinocerebellar ataxias (SCAs), which are a group of genetic disorders that often cause a lack of coordination, difficulty walking, slurred speech, tremors, and eventually death. Activation of K_Ca2.2/K_Ca2.3 channels reportedly exerts beneficial effects in SCAs. Here, we report the development and validation of an analytical method for quantitating a recently developed positive allosteric modulator of K_Ca2.2/K_Ca2.3 channels (compound 2q) in mouse plasma.

Methods

Mouse plasma samples (10 μL) containing various concentrations of 2q were subjected to protein precipitation in the presence of a structurally similar …

Identifying The Neural Correlates Of Anticipatory Postural Control: A Novel Fmri Paradigm, Jo Armour Smith, Rongwen Tain, Kelli G. Sharp, Laura M. Glynn, Linda R. Van Dillen, Korinne Henslee, Jesse V. Jacobs, Steven C. Cramer

Physical Therapy Faculty Articles and Research

Altered postural control in the trunk/hip musculature is a characteristic of multiple neurological and musculoskeletal conditions. Previously it was not possible to determine if altered cortical and subcortical sensorimotor brain activation underlies impairments in postural control. This study used a novel fMRI-compatible paradigm to identify the brain activation associated with postural control in the trunk and hip musculature. BOLD fMRI imaging was conducted as participants performed two versions of a lower limb task involving lifting the left leg to touch the foot to a target. For the supported leg raise (SLR) the leg is raised from the knee while the …

Background: Biceps tenodesis (BT) is one alternative treatment to repair of superior labrum anterior to posterior (SLAP) tears. It can be performed as an arthroscopy or open procedure. While there have been studies comparing the outcomes of SLAP repair procedures with BT for the treatment of SLAP tears, literature comparing arthroscopic and open BT for the treatment of SLAP tears is limited. Additionally, no previous study has specifically examined the outcomes of these procedures in female patients.

Hypothesis/Purpose: The purpose of this study was to compare outcomes following Arthroscopic BT and Open BT for SLAP tears in females. The authors …

The Effect Of Graft Selection On Patients’ Subjective Readiness To Return To Sport After Acl Reconstruction, Adeeb Hanna, William Johns, Emma Johnson, Bryson Kelmer, Gabriel Onor, Kevin Freedman, Christopher Dodson, Michael Ciccotti

Rowan-Virtua Research Day

Background: Patients who undergo ACL reconstruction with allografts may have an easier functional recovery compared to autograft patients. This is due to decreased donor site morbidity and less muscle atrophy compared to autograft patients. This “easier” recovery may be perceived by patients and may result in a subjective earlier readiness for return to sports.

Hypothesis/Purpose: To determine if there is a difference in perceived readiness to return to sport (RTS) in the first year postoperative period between individuals who undergo ACL reconstruction utilizing bone-patellar tendon-bone (BTB) autografts or allografts.

Study Design: Prospective Cohort Study, Level II Methods: This was a …

Maackia Amurensis Seed Lectin (Masl) Increases Movement Velocity Of Mice With Tnfα Induced Rheumatoid Arthritis, Amanda A. Greenspan, Kelly L. Hamilton, Alan J. Shienbaum, Bradford Fischer, Andrea Bottaro, Gary S. Goldberg

Rowan-Virtua Research Day

Up to 70 million people around the world suffer from rheumatoid arthritis. Current treatment options have varied efficacy and can cause unwanted side effects. New approaches are needed to treat this condition. Sialic acid modifications on chondrocyte receptors have been associated with arthritic inflammation and joint destruction. The transmembrane mucin receptor protein podoplanin (PDPN) has been identified as a functionally relevant receptor that presents extracellular sialic acid motifs. PDPN signaling promotes inflammation and invasion associated with arthritis and, therefore, has emerged as a target that can be used to inhibit arthritic inflammation. Maackia amurensis seed lectin (MASL) can target PDPN …

Localization Of Ctg-Repeat-Containing Transgenes In Drosophila Melanogaster Myotonic Dystrophy Models, Andrea Waltrip

Departmental Honors & Graduate Capstone Projects

Myotonic Dystrophy Type 1, DM1, is a multi-systemic muscle wasting disorder that results from expression of expanded CTG repeats in the DMPK gene in humans. Three transgenic Drosophila melanogaster lines have been created containing 60, 250, or 480 CTG repeats to model DM1. The transgenic repeats are expressed using the GAL4/UAS system. Expression of long-repeat transgenes ((CTG)₂₅₀ and i(CTG)₄₈₀) produces phenotypes consistent with DM1, relative to control lines ((CTG)₆₀). The precise chromosomal location of insertion of the transgenes has not been reported. We used classical genetic approaches to localize CTG-repeat transgene insertion to a specific …

The purpose of this study was to determine if a cohort of former or current smokers at time of surgery met the minimally clinical important difference (MCID) for Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS-UE), Depression (PROMIS-D), and Pain Interference (PROMIS-PI) scores in comparison to nonsmokers.

Methods: A retrospective review of patients who underwent rotator cuff repair was performed. Patients who completed preoperative and 6-month postoperative PROMIS scores were included. The MCID was calculated using a distribution technique with a threshold of 0.5 …

Minimalistic Approach To Enhanced Recovery After Pediatric Scoliosis Surgery, Scott A. Barnett, Bryant M. Song, Matthew Bauer, Matthew E. Nungesser, Claudia Leonardi, Michael J. Heffernan

School of Medicine Faculty Publications

Purpose: Prior studies of enhanced recovery protocols (ERP) have been conducted at large institutions with abundant resources. These results may not apply at institutions with less resources directed to quality improvement efforts. The purpose of this study was to assess the value of a minimalistic enhanced recovery protocol in reducing length of stay (LOS) following PSF for adolescent idiopathic scoliosis. We hypothesized that accelerated transition to oral pain medications and mobilization alone could shorten hospital length of stay in the absence of a formal multimodal pain regimen. Methods: AIS patients aged 10–18 who underwent PSF at a tertiary pediatric hospital …
