Ethnic disparities in the risk of colorectal adenomas associated with aspirin and statin use: a retrospective multiethnic study.

Background: Although data on the inverse association between colorectal adenomas (CRA) and daily aspirin or statin therapy exists in white and black patients, scarce data exists on these associations in the Hispanic population. With a rapidly increasing Hispanic population in the United States, defining the association in Hispanics is crucial.

Methods: The study sample included 1,843 consecutive patients who underwent a colonoscopy (screening or diagnostic) from 2009 to 2011 at a community hospital in East Meadow, New York.

Unique feeding morphology in a new prognathous extinct porpoise from the Pliocene of California.

Modern porpoises (Odontoceti: Phocoenidae) are some of the smallest cetaceans and usually feed near the seafloor on small fish and cephalopods [1-3]. Within both extinct and extant phocoenids, no evidence for specialized mandibular morphology has been documented [4-7]. Here we describe a new species of extinct porpoise, Semirostrum ceruttii, from the marine Pliocene San Diego (4.

Unusual soft-tissue preservation of a crocodile lizard (Squamata, Shinisauria) from the green river formation (Eocene) and shinisaur relationships.

We describe an unusual squamate fossil from the Green River Formation (Uintan, Eocene) from the Piceance Creek Basin, Colorado, USA. The new specimen, USNM PAL 540708, is a small fossil squamate skin lacking skeletal elements. It is preserved as a part and counterpart in fine-grained limestone.

Impact of academic affiliation and training on knowledge of hereditary colorectal cancer.

Background: Knowledge about hereditary colorectal cancer (CRC) can aid cancer screening and prevention in high-risk patients. Genetic testing, once conducted primarily at academic centers, is now routinely performed in a variety of clinics. Nonacademic physicians may not be aware of hereditary CRC standards of care.

Improvement of left ventricular remodeling after myocardial infarction with eight weeks L-thyroxine treatment in rats.

Background: Left ventricular (LV) remodeling following large transmural myocardial infarction (MI) remains a pivotal clinical issue despite the advance of medical treatment over the past few decades. Identification of new medications to improve the remodeling process and prevent progression to heart failure after MI is critical. Thyroid hormones (THs) have been shown to improve LV function and remodeling in animals post-MI and in the human setting.
