Expression And Function Of Hypoxia Inducible Factor-1 Alpha In Human Melanoma Under Non-Hypoxic Conditions, Caroline N. Mills, Sandeep S. Joshi, Richard M. Niles

Richard M. Niles

Background Hypoxia inducible factor-1 alpha (HIF-1α) protein is rapidly degraded under normoxic conditions. When oxygen tensions fall HIF-1α protein stabilizes and transactivates genes involved in adaptation to hypoxic conditions. We have examined the normoxic expression of HIF-1α RNA and protein in normal human melanocytes and a series of human melanoma cell lines isolated from radial growth phase (RGP), vertical growth phase (VGP) and metastatic (MET) melanomas. Results HIF-1α mRNA and protein was increased in RGP vs melanocytes, VGP vs RGP and MET vs VGP melanoma cell lines. We also detected expression of a HIF-1α mRNA splice variant that lacks part …

Analysis Of The Effects And Current Treatments Of Laminin Deficiency, Joshua Mark Reynolds

Senior Honors Theses

Laminin (LM) is a network of proteins that functions as a connective framework of most cells in the body. It is composed of multiple different subunits and therefore has many different variations. It is a trimeric protein, meaning that it is composed primarily of ⍺, β, and γ chains. The differentiation of these subunits is what gives the different variants their functions. In addition, although LM is the primary molecule in scope, the network of other connective proteins involved in LM-associated diseases will also be covered in lesser detail because molecules like dystrophin, dystroglycan, collagen, and integrin are vital to …

Frequency And Clinical Variants Of Specific Dermatoses In Third Trimester Of Pregnancy: A Study From A Tertiary Care Centre, Sadra Masood, Dilawar Abbas Rizvi, Saadia Tabassum, Shaheen Akhtar, Rehan Uddin Alvi

Section of Internal Medicine

OBJECTIVE: To determine the frequency of patients with dermatoses in the third trimester of pregnancy and to identify various clinical types of dermatoses in the third trimester.

METHODS: The study was carried out at the Department of Dermatology and the Department of Gynaecology & Obstetrics, PNS Shifa Hospital, Karachi, from January 2 to July 1, 2008. Two hundred pregnant women in their third trimester were included in the study. The diagnosis was based on history, clinical examination and relevant investigations. Patients with physiological dermatoses and dermatoses which flare up during pregnancy were excluded. A comprehensive pro-forma was used to evaluate …

The Mechanical Behavior Of Mutant K14-R125p Keratin Bundles And Networks In Neb-1 Keratinocytes, Daniel R. Beriault, Oualid Haddad, John V. Mccuaig, Zachary J. Robinson, David Russell, E. Birgitte Lane, Douglas S. Fudge

Epidermolysis bullosa simplex (EBS) is an inherited skin-blistering disease that is caused by dominant mutations in the genes for keratin K5 or K14 proteins. While the link between keratin mutations and keratinocyte fragility in EBS patients is clear, the exact biophysical mechanisms underlying cell fragility are not known. In this study, we tested the hypotheses that mutant K14-R125P filaments and/or networks in human keratinocytes are mechanically defective in their response to large-scale deformations. We found that mutant filaments and networks exhibit no obvious defects when subjected to large uniaxial strains and have no negative effects on the ability of human …

Is Acupuncture Effective In Reducing Itch Intensity And Wheal Size In Patients With Dermatologic Conditions?, Melanie Schwer

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this selective EBM review is to determine whether acupuncture is effective in reducing itch intensity and wheal size in patients with dermatologic conditions.

STUDY DESIGN: Review of all English language primary randomized controlled trials published after 1984

DATA SOURCES: Three randomized controlled trials were found using Pubmed database.

OUTCOMES MEASURED: The three trials measured various outcomes: Visual Analog Scale (VAS); Eppendorf Itch Questionnaire; Cumulative Itch Index; Perimeter of wheal and flare size before, during, & after acupuncture; Psoriasis Area and Severity Index (PASI)

RESULTS: Belgrade et al. found statistically significant improvement in itch intensity and flare …

Is Ceftobiprole A Safe And Effective Treatment For Skin And Skin Structure Infections?, Laura Thompson

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this systematic review is to determine whether or not ceftobiprole is a safe and effective treatment for complicated skin and skin structure infections

STUDY DESIGN: Review of all English language primary randomized controlled trials from 1996-2010

DATA SOURCES: Three randomized controlled trials were found using Pubmed and Cochrane databases

OUTCOMES MEASURES: Skin or skin-structure infection cure with ceftobiprole intervention and adverse effects of this new pharmaceutical. Cure or failure to cure skin infection was determined based on both clinical and microbiological assessment. Adverse events were measured based on patient reports, clinician reports, labs, and vital sign …

Volume Measures Using A Digital Image Analysis System Are Reliable In Diabetic Foot Ulcers, Sue Gardner, Rita Frantz, Stephen Hillis, Thomas Blodgett, Lorraine Femino, Shannon Lehman

Thomas Blodgett

Reliable measures of wound size are critical to wound healing research and clinical management. Measurement of full-thickness wounds is increasingly being done using digital images and photogrammetric software, such as VeVMD (Vista Medical, Winnipeg, Manitoba, Canada), to estimate wound volume. The reliability of VeVMD in determining wound volume is unknown. The present study sought to examine the reliability of wound volume measurements obtained using VeVMD.
