Immunology of inflammatory bowel disease.

Current opinion in gastroenterology

Levine AD, Fiocchi C.
PMID: 17031093
Curr Opin Gastroenterol. 2000 Jul;16(4):306-9. doi: 10.1097/00001574-200007000-00003.

The immunology of inflammatory bowel disease continues to be an intense area of investigation for clues to the pathogenesis of Crohn disease and ulcerative colitis. As typical with complex diseases, inflammatory bowel disease research is continuously evolving. Without abandoning...

The repeated acquisition of behavioral chains.

Journal of the experimental analysis of behavior

Boren JJ, Devine DD.
PMID: 16811312
J Exp Anal Behav. 1968 Nov;11(6):651-60. doi: 10.1901/jeab.1968.11-651.

Monkeys were trained with food reinforcement in a chamber containing four groups of three levers. For each session the monkey's task was to learn a new four-response chain by pressing the correct lever in each group. A stable pattern...

Propagation of interacting force chains in the continuum limit.

Physical review. E, Statistical, nonlinear, and soft matter physics

Roichman Y, Levine D, Yavneh I.
PMID: 15697349
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Dec;70(6):061301. doi: 10.1103/PhysRevE.70.061301. Epub 2004 Dec 03.

We study the effect of mergers in the force chain model describing the stress profile in static granular materials. Combining numerical and analytical calculations, we show that granular materials do not generally behave in an elasticlike manner; however, they...

Does Non-Exercise Activity Thermogenesis Contribute to Non-Shivering Thermogenesis?.

Journal of thermal biology

Harris AM, Macbride LR, Foster RC, McCrady SK, Levine JA.
PMID: 17404604
J Therm Biol. 2006 Dec;31(8):634-638. doi: 10.1016/j.jtherbio.2006.08.007.

We wanted to examine if spontaneous physical activity contributes to non-shivering thermogenesis. Ten lean, healthy male subjects wore a physical activity, micro-measurement system whilst the room temperature was randomly altered at two hourly intervals between thermoneutral (72°F), cool (62°F)...

A mechanical representation of entropy for a large finite system.

The Journal of chemical physics

Gross A, Levine RD.
PMID: 17042618
J Chem Phys. 2006 Oct 14;125(14):144516. doi: 10.1063/1.2357149.

The temporal evolution of the entropy of a mechanical system as described by a single trajectory is computed using the Clausius [Philos. Mag. 40, 122 (1868)] equality. This requires computing the maximal work that can be done by the...

Ice flexure forced by internal wave packets in the arctic ocean.

Science (New York, N.Y.)

Czipott PV, Levine MD, Paulson CA, Menemenlis D, Farmer DM, Williams RG.
PMID: 17787172
Science. 1991 Nov 08;254(5033):832-5. doi: 10.1126/science.254.5033.832.

Tiltmeters on the Arctic Ocean were used to measure flexure of the ice forced by an energetic packet of internal waves riding the crest of diurnal internal bores emanating from the Yermak Plateau, north of the Svalbard Archipelago. The...

Very-Long-Baseline Radio Interferometry: The Mark III System for Geodesy, Astrometry, and Aperture Synthesis.

Science (New York, N.Y.)

Rogers AE, Cappallo RJ, Hinteregger HF, Levine JI, Nesman EF, Webber JC, Whitney AR, Clark TA, Ma C, Ryan J, Corey BE, Counselman CC, Herring TA, Shapiro II, Knight CA, Shaffer DB, Vandenberg NR, Lacasse R, Mauzy R, Rayhrer B, Schupler BR, Pigg JC.
PMID: 17734328
Science. 1983 Jan 07;219(4580):51-4. doi: 10.1126/science.219.4580.51.

The Mark III very-long-baseline interferometry (VLBI) system allows recording and later processing of up to 112 megabits per second from each radio telescope of an interferometer array. For astrometric and geodetic measurements, signals from two radio-frequency bands (2.2 to...

Inhibition of melanoma angiogenesis by telomere homolog oligonucleotides.

Journal of oncology

Coleman C, Levine D, Kishore R, Qin G, Thorne T, Lambers E, Sasi SP, Yaar M, Gilchrest BA, Goukassian DA.
PMID: 20652008
J Oncol. 2010;2010:928628. doi: 10.1155/2010/928628. Epub 2010 Jun 28.

Telomere homolog oligonucleotides (T-oligos) activate an innate telomere-based program that leads to multiple anticancer effects. T-oligos act at telomeres to initiate signaling through the Werner protein and ATM kinase. We wanted to determine if T-oligos have antiangiogenic effects. We...

Time transfer using multi-channel GPS receivers.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Levine J.
PMID: 18238436
IEEE Trans Ultrason Ferroelectr Freq Control. 1999;46(2):392-8. doi: 10.1109/58.753028.

This report is on time transfer experiments using a Global Positioning System (GPS) receiver constructed using a commercial GPS "engine" and a standard PC. The receiver measures the time difference between the local clock and a 1 pps signal...

Implications of the mechanical (PCI) vs thrombolytic controversy for ST segment elevation myocardial infarction on the organization of emergency medical services: the Boston EMS experience.

Critical pathways in cardiology

Moyer P, Feldman J, Levine J, Beshansky J, Selker HP, Barnewolt B, Brown DF, Cardoza JP, Grossman SA, Jacobs A, Kerman BJ, Kimmelstiel C, Larson R, Losordo D, Pearlmutter M, Pozner C, Ramirez A, Rosenfield K, Ryan TJ, Zane RD, Cannon CP.

With the many advances in rapid reperfusion therapy for management of acute ST segment elevation myocardial infarction (STEMI), there is a need to revisit the current plan for prehospital triage (point of entry). Until recently in Boston, and nationwide,...

Obesity and medical illnesses in psychiatric patients admitted to a long-term psychiatric facility.
