Circadian influences on myocardial infarction
(2014-10-30)
Components of circadian rhythm maintenance, or “clock genes,” are endogenous entrainable oscillations of about 24 h that regulate biological processes and are found in the suprachaismatic nucleus (SCN) and many peripheral ...
How Sweet It Is: Traditional Sweet Iced Tea and the Diabesity Epidemic.
(2015-01)
In this paper we present four cases from our medical practice to increase awareness of the role of sweet tea in obesity and diabetes management. We start with a history of Southern style “sweet tea”, and discuss the ...
THE EFFECTS OF ACIDIC TUMOR MICROENVIRONMENT ON LYMPHOMA CELL RESPONSES TO CHEMOTHERAPEUTICS
(East Carolina University, 2014)
Acidic tumor microenvironment exists in many types of cancer. Altered glycolytic metabolism of tumor cells and deficient blood supply in tissues are major causes for this phenomenon. Lymphoma cells may have different ...
Is type II diabetes mellitus (NIDDM) a surgical disease?
(East Carolina University, 1992-06)
Since February 1, 1980, 515 morbidly obese patients have undergone
the Greenville gastric bypass (GGB) operation. Of these,
212 (41.2%) were euglycemic, 288 (55.9%) were either diabetic
or had glucose intolerance, and ...

Objective:
To investigate the relationship between the tumour volume and metabolic rates of astrocytic tumours using MR spectroscopy (MRS) during radiation therapy (RT).
Methods:
12 healthy male Sprague-Dawley® rats ...
Molecular mechanism of anandamide-induced apoptosis in non-melanoma skin cancer.
(East Carolina University, 2015)
Non-melanoma skin cancer (NMSC) is the most common cancer in the United States. The absence of selective toxicity is the major problem associated with chemotherapeutic and radiation therapy for NMSCs. The goal of the present ...
Osteomyelitis Infection of Mycobacterium marinum: A Case Report and Literature Review
(2014-12)
Mycobacterium marinum (M. marinum) is a ubiquitous waterborne organism that grows optimally at temperatures around 30°C. It is a nontuberculous Mycobacterium found in nonchlorinated water with worldwide prevalence. It is ...

The unique roles of IFE-1, a germline-specific isoform of eukaryotic translation factor 4E, during gametogenesis
(East Carolina University, 2009)
Fertility and embryonic viability are measures of efficient germ cell growth and differentiation. During oogenesis, spermatogenesis and embryogenesis cells initially proliferate then differentiate into specific tissues. New proteins are required for both cell growth and differentiation, requiring qualitative and quantitative changes in protein synthesis. During late gametogenesis and early embryogenesis the expression of the appropriate proteins is a primarily due to translational control. Translational control of mRNAs is mediated in part by eukaryotic initiation factor 4E (eIF4E). eIF4E binds the methylated 5' cap of mRNA and recruits it to the ribosome. The nematode worm C.elegans expresses five isoforms of eIF4E (termed IFE-1 through 5). IFE-1 is expressed primarily in the germline and is the only isoform that associates with P granules by binding directly to PGL-1. P granules are ribonucleoprotein particles (RNPs) that contain stored mRNAs and proteins needed for oogenesis and early embryogenesis. Using a strain that lacks IFE-1, I assessed the translational efficiency of maternal mRNAs bound and not bound to P granules by polysome fractionation. Translation of pos-1, pal-1, mex-1, oma-1, ced-4 and glp-1 mRNAs was inefficient in the ife-1 strain relative to wild type worms. GAPDH (gpd-3) mRNA translation was not affected. We also observed differences in the pattern of expression of the MEX-1 protein during oogenesis. In males, secondary spermatocytes failed to complete cytokinesis at 25°C in absence of IFE-1. Males deficient of IFE-1 therefore lacked mature sperm. In addition, ife-1 spermatocytes prematurely accumulated pro-apoptotic CED-4, homolog to mammalian Apaf-1, during spermatogenesis. In ife-1 worms fertility was decreased by 80% due to decreased viability of both oocytes and spermatocytes. Our data indicate two unique roles for eIF4E (IFE-1 isoform) in late oogenesis and spermatogenesis. We suggest that IFE-1 preferentially recruits regulated mRNAs at critical times during germ cell development. ...
