Faster Movement Speed Results In Greater Tendon Strain During The Loaded Squat Exercise, Jacob E. Earp, Robert U. Newton, Prue Cormie, Anthony J. Blazevich

Research outputs 2014 to 2021

Introduction:

Tendon dynamics influence movement performance and provide the stimulus for long-term tendon adaptation. As tendon strain increases with load magnitude and decreases with loading rate, changes in movement speed during exercise should influence tendon strain.

Methods:

Ten resistance-trained men [squat one repetition maximum (1RM) to body mass ratio: 1.65 ± 0.12] performed parallel-depth back squat lifts with 60% of 1RM load at three different speeds: slow fixed-tempo (TS: 2-s eccentric, 1-s pause, 2-s concentric), volitional-speed without a pause (VS) and maximum-speed jump (JS). In each condition joint kinetics, quadriceps tendon length (LT), patellar tendon force (FT …

Analgesia Followed By Long-Term Hyperalgesia Generated By Disinhibition Of The Basolateral Amygdala, Derek Atchley Jan 2016

Analgesia Followed By Long-Term Hyperalgesia Generated By Disinhibition Of The Basolateral Amygdala, Derek Atchley

Wayne State University Theses

Stress produces bimodal effects on pain peception. During exposure to a stressor pain responses are inibited (i.e. stress-induced analgesia). However, following long-term exposure to a stressor increases in responsiveness to painful stimuli may develop (i.e. stress-induced hyperalgesia). Here I evaluated how a key component of the subcortical defense circuit and target of stress hormones contributes to the development of both stress-induced analgesia and hyperalgesia. Bicuculline methiodide, a GABAA antagonist, injected into the basolateral amygdala was used to mimic the neural effects of a stressor or threat exposure. Immediately following injection pain responsiveness was decreased as measured by vocalizations after discharge …

Epigenetics And Shared Molecular Processes In The Regeneration Of Complex Structures, Labib Rouhana, Junichi Tasaki Jan 2016

Epigenetics And Shared Molecular Processes In The Regeneration Of Complex Structures, Labib Rouhana, Junichi Tasaki

Biological Sciences Faculty Publications

The ability to regenerate complex structures is broadly represented in both plant and animal kingdoms. Although regenerative abilities vary significantly amongst metazoans, cumulative studies have identified cellular events that are broadly observed during regenerative events. For example, structural damage is recognized and wound healing initiated upon injury, which is followed by programmed cell death in the vicinity of damaged tissue and a burst in proliferation of progenitor cells. Sustained proliferation and localization of progenitor cells to site of injury give rise to an assembly of differentiating cells known as the regeneration blastema, which fosters the development of new tissue. Finally, …


Identification And Characterization Of Dna Repair Snf2/Swi2 Atpases In Tetrahymena Thermophila, Andrew Francis Morin Jan 2016

Identification And Characterization Of Dna Repair Snf2/Swi2 Atpases In Tetrahymena Thermophila, Andrew Francis Morin

Graduate Theses/Dissertations

The Snf2/Swi2 ATPases Rad5 and Rad16 have been shown to play vital roles in a number of DNA repair pathways. In both Saccharomyces cerevisiae and human cell lines, Rad5 homologs (SHPRH, HLTF) have been shown to function in DNA double strand break (DSB) repair along with pathways that repair damage after replication. The function of Rad16, unlike Rad5, has been found only in lower eukaryotes such as Saccharomyces, despite the fact that it plays an essential role in nucleotide excision repair (NER), and more specifically in the repair of silenced areas of the genome. In order to more fully understand …

The Level Of Nmda Receptor In The Membrane Modulates Amyloid-Β Association And Perforation, Christian Peters, Fernando J. Sepúlveda, Eduardo Fernández-Pérez, Robert W. Peoples, Luis G. Aguayo

Biomedical Sciences Faculty Research and Publications

Alzheimer’s disease is a neurodegenerative disorder that affects mostly the elderly. The main histopathological markers are the senile plaques formed by amyloid-β peptide (Aβ) aggregates that can perforate the plasma membrane of cells, increasing the intracellular calcium levels and releasing synaptic vesicles that finally lead to a delayed synaptic failure. Several membrane proteins and lipids interact with Aβ affecting its toxicity in neurons. Here, we focus on NMDA receptors (NMDARs) as proteins that could be modulating the association and neurotoxic perforation induced by Aβ on the plasma membrane. In fact, our results showed that decreasing NMDARs, using enzymatic or siRNA …

An important component of precision medicine-the use of whole-genome sequencing (WGS) to guide lifelong healthcare-is electronic decision support to inform drug choice and dosing. To achieve this, automated identification of genetic variation in genes involved in drug absorption, distribution, metabolism, excretion and response (ADMER) is required. CYP2D6 is a major enzyme for drug bioactivation and elimination. CYP2D6 activity is predominantly governed by genetic variation; however, it is technically arduous to haplotype. Not only is the nucleotide sequence of CYP2D6 highly polymorphic, but the locus also features diverse structural variations, including gene deletion, duplication, multiplication events and rearrangements with the nonfunctional, …

Introduction To Bioethics Special Supplement V: Ethical Issues In Genomic Testing Of Children., John D. Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Next-generation genome sequencing of children is one of the most promising and most challenging new technologies in pediatrics. On the one hand, it offers the hope that we will be able to diagnose rare conditions that were previously impossible to diagnose, which, in turn, might lead to new treatments. On the other hand, the technology for sequencing presents daunting problems of interpretation. It is problematic to conduct the research necessary to characterize the pathogenicity of those variants at the same time that we are using them to guide the clinical care of children who have complex medical problems. It is …


Estrogen Regulation Of Mir-181a Stability In Neurons, Chun Kim Jan 2016

Estrogen Regulation Of Mir-181a Stability In Neurons, Chun Kim

Master's Theses

Estrogens are an important class of steroid hormones involved in many cellular signaling processes. Levels of estrogens fluctuate across the lifespan suggesting that they target intracellular mediators, such as microRNAs, to fine-tune homeostatic cellular processes. Previous work in our lab demonstrated that 17β-estradiol (E2), the predominant circulating estrogen, stabilized miR-181a in a neuronal cell line derived from rat hypothalamus. These results lead to the hypothesis that E2 regulated miR-181a stability by altering the pool of endogenous RNA and by recruiting PNRC2 away from the miRNA degradation machinery. By utilizing miRNA degradation assays and immunostaining techniques, it was determined that the …

Euglycemic Diabetic Ketoacidosis In A 27 Year-Old Female Patient With Type-1-Diabetes Treated With Sodium-Glucose Cotransporter-2 (Sglt2) Inhibitor Canagliflozin, Nimrah Bader, Lubna Mirza

Medical College Documents

We are reporting a timely case of atypical euglycemic diabetic ketoacidosis in a type 1 diabetic patient treated with sodium-glucose cotransporter-2 (SGLT-2) inhibitor canagliflozin. The clinical history, physical examination findings and laboratory values are described. Other causes of acidosis such as salicylate toxicity or alcohol intoxication were excluded. Ketoacidosis resolved after increasing dextrose and insulin doses supporting the hypothesis that SGLT-2 inhibitors may lead to hypoinsulinemia. Euglycemic ketoacidosis did not recur in our patient after discontinuing canagliflozin. We recommend reserving SGLT2 inhibitor therapy to type 2 diabetics, discontinuing medication and treating patients presenting with ketoacidosis due to SGLT-2 inhibitors with …

Genomic Imbalances In Peripheral Blood Confirm The Diagnosis Of Myelodysplastic Syndrome In A Patient Presenting With Non-Immune Hemolytic Anemia, Mohammad Faizan Zahid, Nadia Khan, Jianming Pei, Joseph R. Testa, Essel Dulaimi

Medical College Documents

Myelodysplastic syndrome (MDS) is a clonal stem-cell disorder characterized by dyshematopoiesis. We report a patient who presented with cytopenias and microangiopathic hemolytic anemia. Chromosome microarray analysis (CMA), using single nucleotide polymorphism arrays, on peripheral blood revealed genomic imbalances indicative of MDS, which was confirmed by bone marrow examination. This report highlights the importance of suspecting MDS in patients with cytopenias and microangiopathic hemolytic anemia. CMA of peripheral blood may assist in the preliminary diagnosis of MDS, representing a comparatively less invasive diagnostic procedure and may aid bone marrow evaluation when an aspirate sample is insufficient for conventional cytogenetic analysis.
