Lesula: A New Species Of Cercopithecus Monkey Endemic To The Democratic Republic Of Congo And Implications For Conservation Of Congo’S Central Basin, John A. Hart, Kate M. Detwiler, Christopher C. Gilbert, Andrew S. Burrell, James L. Fuller, Maurice Emetshu, Terese B. Hart, Ashley Vosper, Eric J. Sargis, Anthony J. Tosi

Publications and Research

In June 2007, a previously undescribed monkey known locally as “lesula” was found in the forests of the middle Lomami Basin in central Democratic Republic of Congo (DRC). We describe this new species as Cercopithecus lomamiensis sp. nov., and provide data on its distribution, morphology, genetics, ecology and behavior. C. lomamiensis is restricted to the lowland rain forests of central DRC between the middle Lomami and the upper Tshuapa Rivers. Morphological and molecular data confirm that C. lomamiensis is distinct from its nearest congener, C. hamlyni, from which it is separated geographically by both the Congo (Lualaba) and the Lomami …

Temporal Changes In Collagen Cross-Links In Spontaneous Articular Cartilage Repair, Masahiko Terajima, Sheela Damle, Madhuri Penmatsa, Paul West, Mathias Bostrom, Chisa Hidaka, Mitsuo Yamauchi, Nancy Pleshko

Publications and Research

Objective: Little is known about how the biochemical properties of collagen change during tissue regeneration following cartilage damage. In the current study, temporal changes in cartilage repair tissue biochemistry were assessed in a rabbit osteochondral defect. Design: Bilateral full-thickness 3-mm osteochondral trochlear groove defects were created in 54 adult male skeletally mature New Zealand white rabbits, and tissue repair was monitored over 16 weeks. Collagen content, cross-links, lysyl hydroxylation, gene expression, histological grading, and Fourier transform infrared analyses were performed at 2, 4, 6, 8, 12, and 16 weeks. Results: Defect fill occurred at ~4 weeks postinjury; however, histological grading …

Composition Of The Adult Digestive Tract Bacterial Microbiome Based On Seven Mouth Surfaces, Tonsils, Throat And Stool Samples, Nicola Segata, Susan Kinder Haake, Peter Mannon, Katherine P. Lemon, Levi Waldron, Dirk Gevers, Curtis Huttenhower, Jacques Izard

Publications and Research

Background: To understand the relationship between our bacterial microbiome and health, it is essential to define the microbiome in the absence of disease. The digestive tract includes diverse habitats and hosts the human body’s greatest bacterial density. We describe the bacterial community composition of ten digestive tract sites from more than 200 normal adults enrolled in the Human Microbiome Project, and metagenomically determined metabolic potentials of four representative sites.

Results: The microbiota of these diverse habitats formed four groups based on similar community compositions: buccal mucosa, keratinized gingiva, hard palate; saliva, tongue, tonsils, throat; sub- and supra-gingival plaques; and stool. …

Squalicorax Chips A Tooth: A Consequence Of Feeding-Related Behavior From The Lowermost Navesink Formation (Late Cretaceous: Campanian-Maastrichtian) Of Monmouth County, New Jersey, Usa, Martin A. Becker, John A. Chamberlain Jr.

Publications and Research

Chipped and broken functional teeth are common in modern sharks with serrated tooth shape. Tooth damage consists of splintering, cracking, and flaking near the cusp apex where the enameloid is broken and exposes the osteodentine and orthodentine. Such damage is generally viewed as the result of forces applied during feeding as the cusp apex impacts the skeletal anatomy of prey. Damage seen in serrated functional teeth from sharks Squalicorax kaupi [1] and Squalicorax pristodontus [1] from the late Cretaceous lowermost Navesink Formation of New Jersey resembles that occurring in modern sharks and suggests similar feeding behavior. Tumbling experiments using serrated …

A Chemical Specialty Semantic Network For The Unified Medical Language System, C Paul Morrey, Yehoshua Perl, Michael Halper, Ling Chen, Huanying “Helen” Gu

Publications and Research

Background Terms representing chemical concepts found the Unified Medical Language System (UMLS) are used to derive an expanded semantic network with mutually exclusive semantic types. The UMLS Semantic Network (SN) is composed of a collection of broad categories called semantic types (STs) that are assigned to concepts. Within the UMLS’s coverage of the chemical domain, we find a great deal of concepts being assigned more than one ST. This leads to the situation where the extent of a given ST may contain concepts elaborating variegated semantics. A methodology for expanding the chemical subhierarchy of the SN into a finer-grained categorization …

A Macroepigenetic Approach To Identify Factors Responsible For The Autism Epidemic In The United States, Renee Dufault, Walter J. Lukiw, Raquel Crider, Roseanne Schnoll, David Wallinga, Richard Deth

Publications and Research

The number of children ages 6 to 21 in the United States receiving special education services under the autism disability category increased 91% between 2005 to 2010 while the number of children receiving special education services overall declined by 5%. The demand for special education services continues to rise in disability categories associated with pervasive developmental disorders. Neurodevelopment can be adversely impacted when gene expression is altered by dietary transcription factors, such as zinc insufficiency or deficiency, or by exposure to toxic substances found in our environment, such as mercury or organophosphate pesticides. Gene expression patterns differ geographically between populations …

Advances In Ultrafast Time Resolved Fluorescence Physics For Cancer Detection In Optical Biopsy, R. R. Alfano

Publications and Research

We discuss the use of time resolved fluorescence spectroscopy to extract fundamental kinetic information on molecular species in tissues. The temporal profiles reveal the lifetime and amplitudes associated with key active molecules distinguishing the local spectral environment of tissues. The femtosecond laser pulses at 310 nm excite the tissue. The emission profile at 340 nm from tryptophan is non-exponential due to the micro-environment. The slow and fast amplitudes and lifetimes of emission profiles reveal that cancer and normal states can be distinguished. Time resolved optical methods offer a new cancer diagnostic modality for the medical community.

Evidence For A Grooming Claw In A North American Adapiform Primate: Implications For Anthropoid Origins, Stephanie Maiolino, Doug M. Boyer, Jonathan I. Bloch, Christopher C. Gilbert, Joseph Groenke

Publications and Research

Among fossil primates, the Eocene adapiforms have been suggested as the closest relatives of living anthropoids (monkeys, apes, and humans). Central to this argument is the form of the second pedal digit. Extant strepsirrhines and tarsiers possess a grooming claw on this digit, while most anthropoids have a nail. While controversial, the possible presence of a nail in certain European adapiforms has been considered evidence for anthropoid affinities. Skeletons preserved well enough to test this idea have been lacking for North American adapiforms. Here, we document and quantitatively analyze, for the first time, a dentally associated skeleton of Notharctus tenebrosus …

Relationships Between Urinary Biomarkers Of Phytoestrogens, Phthalates, Phenols, And Pubertal Stages In Girls, Tandra R. Chakraborty, Eilliut Alicea, Sanjoy Chakraborty

Publications and Research

Phytoestrogens, phthalates, and phenols are estrogen-disrupting chemicals that have a pronounced effect at puberty. They are exogenous chemicals that are either plant-derived or man-made, and can alter the functions of the endocrine system and cause various health defects by interfering with the synthesis, metabolism, binding, or cellular responses of natural estrogens. Phytoestrogens, phthalates, and phenols are some of the potent estrogens detectable in urine. Phytoestrogens are plant-derived xenestrogens found in a wide variety of food products, like soy-based food, beverages, several fruits, and vegetables. Exposure to phytoestrogens can delay breast development and further lead to precocious puberty. The effect of …

Palatalization In Romanian — Acoustic Properties And Perception, Laura Spinu, Irene Vogel, H. Timothy Bunnell

Publications and Research

This paper presents the results of an acoustic study of fricatives from four places of articulation produced by 31 native speakers of Romanian, as well as those of a perceptual study using the stimuli from the acoustic experiment, allowing for a direct comparison between acoustic properties and perception. It was found that there are greater acoustic differences between plain and palatalized labials and dorsals as compared to coronals. The acoustic results were paralleled by the perceptual findings. This pattern departs from cross-linguistic generalizations made with respect to the properties of secondary palatalization. A likely source of the differences is the …
