Much research is currently ongoing into new therapies for cartilage defect repair with new biomaterials frequently appearing which purport to have significant regenerative capacity. These biomaterials may be classified as medical devices, and as such must undergo rigorous testing before they are implanted in humans. A large part of this testing involves in vitro trials and biomechanical testing. However, in order to bridge the gap between the lab and the clinic, in vivo preclinical trials are required, and usually demanded by regulatory approval bodies. This review examines the in vivo models in current use for cartilage defect repair testing and ...

The purpose of this multicenter, prospective, randomized, placebo-controlled study was to evaluate and compare the efficacy of two cognitive rehabilitation interventions (Memory and Attention Adaptation Training (MAAT) and Attention Builders Training (ABT)), with and without pharmacologic enhancement (i.e., with methylphenidate (MPH) or placebo), for treating persistent cognitive problems after traumatic brain injury (TBI). Adults with a history of TBI at least four months prior to study enrollment with either objective cognitive deficits or subjective cognitive complaints were randomized to receive MPH or placebo and MAAT or ABT, yielding four treatment combinations: MAAT/MPH (N=17), ABT/MPH (N=19 ...


Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson 2016 University of California, Davis

Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson

Michael Johnson

We determined home-range overlap among northern flying squirrels (Glaucomys sabrinus) to assess their spatial organization. We found extensive home-range overlap among females, and though this overlap could reflect social behavior, we found no evidence of attraction among females, with only one instance of den-sharing. Instead, our results suggest that females share foraging areas but may be territorial in portions of the home range, especially around den trees and during young-rearing. Home-range overlap could also result from the extrinsic effect of forest fragmentation due to timber harvest, which might impede dispersal and force squirrels to cluster on remaining fragments of suitable ...


Functional Alterations Of Ion Channels From Cardiac Fibroblasts In Heart Diseases, Gracious R. Ross, Arshad Jahangir 2016 Sheikh Khalifa bin Hamad Al Thani Center for Integrative Research on Cardiovascular Aging, Aurora Research Institute, Aurora Health Care

Functional Alterations Of Ion Channels From Cardiac Fibroblasts In Heart Diseases, Gracious R. Ross, Arshad Jahangir

Journal of Patient-Centered Research and Reviews

In an aged population, cardiovascular disease is the leading cause of fatality and morbidity. Age-related fibrotic remodeling of the heart contributes to progressive myocardial dysfunction. Cardiac fibroblasts (CF), responsible for the maintenance of extracellular matrix and fibrosis process, play an important role in cardiac health and disease. CFs influence myocardial function by their chemical, electrical and mechanical interactions with cardiomyocytes through extracellular matrix deposition or secretion of cytokines and growth factors. These, in turn, are modulated by ion channels, macromolecular pores in the plasma membrane that allow selective ionic fluxes of major ions like K+, Ca2+, Na+ or Cl ...

Journal of Patient-Centered Research and Reviews

Background: Liver transplantation is often associated with massive blood loss due to surgical complexity and the hemostatic abnormalities of end-stage liver disease. Blood transfusions have been associated with increased risk of infection, multiorgan dysfunction, graft loss and mortality.

Purpose: To determine for liver transplantation whether correlation exists between preoperative anemia and transfusion requirements, length of stay or incidence of postoperative infection.

Methods: A retrospective review of liver transplantations from Jan. 1, 2012, to June 30, 2015, was conducted. Packed red blood cell (PRBC), fresh frozen plasma (FFP), platelet and cryoprecipitate units were collected preoperatively, intraoperatively and within the first 48 ...

Journal of Patient-Centered Research and Reviews

Purpose

Excessive fibrosis has been suggested to result from persistence of fibroblasts in injured tissue due to impaired apoptosis, but signaling pathways are not fully defined.

Methods

Suppression of apoptotic cell death following transforming growth factor-β1 (TGF-β1) exposure was studied using the culture of NIH/3T3 mouse embryonic fibroblasts. Caspase-3 activity, propidium iodide staining and annexin V binding induced by Fas-ligand (FasL) in NIH/3T3 fibroblasts in the absence and presence of TGF-β1 was determined, and relative contribution of signaling through Smad2/3 and noncanonical Erk1/2 and Akt pathways was dissected by assessing phosphorylation status of these kinases and ...

Can Bedside Ultrasound Inferior Vena Cava Measurements Accurately Diagnose Congestive Heart Failure In The Emergency Department? A Clin-Iq, Miranda Gaskamp, Mark Blubaugh, Laine H. Mccarthy, Dewey C. Scheid

Journal of Patient-Centered Research and Reviews

Congestive heart failure (CHF) is a major cause of morbidity and mortality. Early diagnosis of CHF in patients presenting to the emergency department with undifferentiated dyspnea would allow clinicians to begin appropriate treatment more promptly. Current guidelines recommend B-type natriuretic peptide (BNP) levels for more accurate diagnosis of CHF in dyspneic patients. Although BNP levels are relatively inexpensive, the test is not usually performed at bedside and results may take up to an hour or more. BNP also may have a “gray zone” in which the values can neither confirm nor rule out CHF. BNP has a reported sensitivity of ...

Get Up, Stand Up: A Brief History Of Sedentarism And Why Movement Is Good Medicine, Tony Federico

Tony Federico

Chairs first emerged as a way for high-status individuals to designate their social standing, and their use was almost exclusively the domain of the affluent class until the Industrial Revolution made affordable, mass-produced seating possible. Prior to this point, the vast majority of people sat on improvised objects such as beds, tree stumps, or benches, or simply squatted on their haunches. Social aspirations, continued technological innovations (e.g. the automobile), and a shift towards sedentary work drove the adoption of the chair until its use became ubiquitous at home, at work, at school, and at play (e.g. computer and ...

Deferoxamine Preventable Hepatocellular Damage, Following Hemorrhagic Shock, Charles F. Babbs, David W. Griffin

Weldon School of Biomedical Engineering Faculty Working Papers

To examine the role of iron in mediating hepatocellular damage during reperfusion after hemorrhagic shock, we studied five groups of n=4 or 5 dogs, bled to reduce mean arterial pressure to 35 mmHg (± 5mrnHg) for three hours and subsequently treated 20 minutes prior to reinfusion of shed blood with either 0.9% saline, 5 ml/kg; deferoxamine, 50 μg/kg in 0.9% saline; 6% pentastarch solution, 5 ml/kg; deferoxamine covalently bound to 6% pentastarch, 50 μg/kg; or iron loaded deferoxamine in 0.9% saline. Saturation of iron binding capacity increased during hemorrhagic shock and remained high ...

Frozen Brain Atlas, Natalie Andrea Builes, Dominick Joseph Casciato, Samantha Taylor Bergoine, Robert Speth 2016 Nova Southeastern University

Frozen Brain Atlas, Natalie Andrea Builes, Dominick Joseph Casciato, Samantha Taylor Bergoine, Robert Speth

Frozen Brain Atlas

The Frozen Brain Atlas provides students, educators, and scientists with a tool to further explore the architecture of the brain. Current brain atlases allow users to navigate sectioned brain tissue using histological staining; however, they fail to capture naturally visible structures post sectioning. Through immediate post sectioning image collection, the natural contrast of the brain reveals unique structural details that are rarely seen by traditional staining procedures. By utilizing indexing and interactive labeling, the Nova Southeastern University Frozen Brain Atlas will allow identification of brain regions when used as a correlative tool for modalities including receptor autoradiography, immunofluorescence, and other ...


The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton 2016 The University of Western Ontario

The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton

Electronic Thesis and Dissertation Repository

Dysregulation of autonomic control often develops with advancing age, favoring a chronic state of heightened sympathetic outflow with parasympathetic withdrawal. However, the mechanisms of this age-related autonomic impairment are not known and may relate to alterations in brain structure (e.g. cortical atrophy) and/or altered neural function, particularly in regions related to the cortical autonomic network, namely, the medial prefrontal cortex (MPFC), insula cortex (IC), and hippocampus (HC). Exercise exerts beneficial effects on brain structure and, in the case of cognition, neurologic function; however, how exercise affects regions of the brain related to autonomic function are not known. This ...

Background: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders caused by defects in the steroid 21 hydroxylase gene (CYP21A2). We studied the spectrum of mutations in CYP21A2 gene in a multi-ethnic population in Pakistan to explore the genetics of CAH. Methods: A cross sectional study was conducted for the identification of mutations CYP21A2 and their phenotypic associations in CAH using ARMS-PCR assay. Results: Overall, 29 patients were analyzed for nine different mutations. The group consisted of two major forms of CAH including 17 salt wasters and 12 simple virilizers. There were 14 phenotypic males and 15 females ...

Efficient Immortalization Of Luminal Epithelial Cells From Human Mammary Gland By Introduction Of Simian Virus 40 Large Tumor Antigen With A Recombinant Retrovirus, Bartek J, Bartkova J, Kyprianou N, El-Nasir Lalani, Staskova Z, Shearer M, Chang S, Taylor Papadimitriou J

El Nasir Lalani

When defined in terms of markers for normal cell lineages, most invasive breast cancer cells correspond to the phenotype of the common luminal epithelial cell found in the terminal ductal lobular units. Luminal epithelial cells cultured from milk, which have limited proliferative potential, have now been immortalized by introducing the gene encoding simian virus 40 large tumor (T) antigen. Infection with a recombinant retrovirus proved to be 50-100 times more efficient than calcium phosphate transfection, and of the 17 cell lines isolated, only 5 passed through a crisis period as characterized by cessation of growth. When characterized by immunohistochemical staining ...

Journal of Patient-Centered Research and Reviews

Purpose

Measurement of the number of circulating tumor cells (CTCs) in the bloodstream has been shown to have prognostic significance in treating breast carcinoma. This pilot study was formulated to determine if stage IV non-small cell lung carcinomas similarly shed malignant cells into the circulation and if their presence has prognostic significance.

Methods

Patients with stage IV non-small cell lung carcinomas were tested once for CTCs in 7.5 ml of their blood prior to receiving any treatments. A proprietary blood collection kit produced by Veridex LLC (Raritan, NJ), which manufactures the instrument that performs the immunomagnetic CELLSEARCH® CTC assay ...


Tissue Compartmentalization And Tropism Of Hiv-1: A Dissertation, Robin L. Brese 2016 University of Massachusetts Medical School

Tissue Compartmentalization And Tropism Of Hiv-1: A Dissertation, Robin L. Brese

GSBS Dissertations and Theses

Despite the development of effective antiretroviral treatments, there is still no cure for HIV-1. Major barriers to HIV-1 eradication include the diversity of intrapatient viral quasispecies and the establishment of reservoirs in tissue sanctuary sites. A better understanding of these populations is required for targeted treatments. While previous studies have examined the relationship between brain and blood or immune tissues, few have looked at and compared the properties of viruses from other tissue compartments. In this study, 75 full length HIV-1 envelopes were isolated from the frontal lobe, occipital lobe, parietal lobe, colon, lung, and lymph node of an HIV-1 ...

The Physiological Responses To Cycling Stress., Moriah Larsen

Skyline - The Big Sky Undergraduate Journal

Background: As the intensity of exercise increases, the risk of incidences for exertional heat illness (EHI) continues to climb. The National Athletic Trainers Association (NATA) has set an official position statement; stating a “gold standard” for obtaining core body temperature is via rectal thermometry. It has been reported that other field-expedient methods of obtaining core body temperature (oral, axillary, tympanic, temporal) are invalid or unreliable sources after intense exercise in hot temperature regions. Purpose: To determine if a relationship exists between rectal temperature measurements and tympanic temperature measurements during intensive long bouts of exercise. Design: Controlled Laboratory Study. Setting: Human ...
