PMID: 26347819
J Skin Cancer. 2015;2015:167847. doi: 10.1155/2015/167847. Epub 2015 Aug 12.

Oculocutaneous albinism which is characterised by impaired melanin biosynthesis is the most common inherited pigmentary disorder of the skin and it is common among Blacks in sub-Saharan Africa. All albinos are at great risk of developing squamous cell carcinoma...

Epstein-Barr Virus and Its Association with Oral Hairy Leukoplakia: A Short Review.

PMID: 27047546
Int J Dent. 2016;2016:4941783. doi: 10.1155/2016/4941783. Epub 2016 Mar 07.

In immunocompromised subjects, Epstein-Barr virus (EBV) infection of terminally differentiated oral keratinocytes may result in subclinical productive infection of the virus in the stratum spinosum and in the stratum granulosum with shedding of infectious virions into the oral fluid...

Assessing Antioxidant Capacity in Brain Tissue: Methodologies and Limitations in Neuroprotective Strategies.

Antioxidants (Basel, Switzerland)

Slemmer JE, Weber JT.
PMID: 26785231
Antioxidants (Basel). 2014 Oct 13;3(4):636-48. doi: 10.3390/antiox3040636.

The number of putative neuroprotective compounds with antioxidant activity described in the literature continues to grow. Although these compounds are validated using a variety of in vivo and in vitro techniques, they are often evaluated initially using in vitro...

The prognostic significance of facial lymphoedema in HIV-seropositive subjects with Kaposi sarcoma.

AIDS research and therapy

Feller L, Masipa J, Wood N, Raubenheimer E, Lemmer J.
PMID: 18226270
AIDS Res Ther. 2008 Jan 29;5:2. doi: 10.1186/1742-6405-5-2.

BACKGROUND: Kaposi Sarcoma (KS) is a multifocal angioproliferative neoplasm characterized by inflammation, oedema, neoangiogenesis and spindle cell proliferation. The pathogenesis of human immunodeficiency virus (HIV)-associated KS (HIV-KS) is multifactorial. HHV-8 is an essential factor but not in itself sufficient...

An unusual lepidopteran sex pheromone system in the bagworm moth.

Science (New York, N.Y.)

Leonhardt BA, Neal JW, Klun JA, Schwarz M, Plimmer JR.
PMID: 17798283
Science. 1983 Jan 21;219(4582):314-6. doi: 10.1126/science.219.4582.314.

The female sex pheromone of the bagworm moth is (R)-1-methylbutyl decanoate. The antipode is biologically inactive and it neither enhances nor detracts from the potency of the R enantiomer. Unlike other moths for which female pheromones have been identified,...

Trace chemicals: the essence of sexual communication systems in heliothis species.

Science (New York, N.Y.)

Klun JA, Plimmer JR, Bierl-Leonhardt BA, Sparks AN, Chapman OL.
PMID: 17813171
Science. 1979 Jun 22;204(4399):1328-30. doi: 10.1126/science.204.4399.1328.

Analysis of heptane-soluble compounds from ovipositors of Heliothis zea and Heliothis virescens shows that both species produce relatively large amounts of (Z)-11-hexadecenal, with traces of (Z)-9-hexadecenal, (Z)-7-hexadecenal, and hexadecanal. Heliothis virescens females differ from Heliothis zea in that they...

Molecular characterization of choline acetyltransferase from Drosophila melanogaster.

Neurochemistry international

Slemmon JR, Salvaterra PM, Roberts E.
PMID: 20488078
Neurochem Int. 1984;6(4):519-25. doi: 10.1016/0197-0186(84)90124-4.

Purified acetyl-CoA: choline O-acetyltransferase (EC 2.3.1.6) from Drosophila melanogaster has been shown to contain two major polypeptides of 67 and 54 K Daltons. However, all enzyme activity is found in a single molecular weight form of approx 67 K...

Air permeation tests with (Z,Z)-3,13-octadecadien-1-ol acetate for reduction in trap catch of peachtree and lesser peachtree borer moths.

Journal of chemical ecology

Gentry CR, Bierl-Leonhardt BA, McLaughlin JR, Plimmer JR.
PMID: 24420596
J Chem Ecol. 1981 May;7(3):575-82. doi: 10.1007/BF00987705.

Air permeation trials were conducted to determine whether trap catches of the peachtree borer (PTB)Synanthedon exitiosa (Say) and lesser peachtree borer (LPTB)S. pictipes (Grote and Robinson) could be reduced through application of the synthetic pheromone of the PTB, (Z,Z)-3,13-octadecadien-1-ol...

Oral Leukoplakia as It Relates to HPV Infection: A Review.

International journal of dentistry

Feller L, Lemmer J.
PMID: 22505902
Int J Dent. 2012;2012:540561. doi: 10.1155/2012/540561. Epub 2012 Feb 28.

Leukoplakia is the most common potentially malignant lesion of the oral cavity and can be categorised according to its clinical appearance as homogeneous or nonhomogenous. Tobacco and areca nut use, either alone or in combination are the most common...

Cell transformation and the evolution of a field of precancerization as it relates to oral leukoplakia.

International journal of dentistry

Feller L, Lemmer J.
PMID: 22007217

Potentially malignant oral leukoplakias arise within precancerized epithelial fields consisting of cytogenetically altered keratinocytes at various stages of transformation. The evolution of a clone of keratinocytes culminating in a precancerous phenotype is a function of the number of mutagenic...

Pathobiology of cancer metastasis: a short account.

Cancer cell international

Feller L, Kramer B, Lemmer J.

Cancer-initiating cells display aberrant functional and phenotypic characteristics of normal stem cells from which they evolved by accumulation of multiple cytogenetic and/or epigenetic alterations. Signal transduction pathways which are essential for normal stem cell function are abnormally expressed by...
