Cardiac Tumor Within the Left Ventricle: Thrombus or Something Else?

Papillary fibroelastoma is a benign cardiac tumor that most commonly arises from the valvular endocardium and is typically resected because of its predisposition to cause embolic complications. In this clinical vignette, we describe the case of a patient who presented with a round, mobile 1.3 × 1.

Qualitative and Quantitative Effects of PCSK9 Inhibitors in familial Hypercholesterolemia: a Synthetic Review.

Familial hypercholesterolemia (FH) is an autosomal dominant disease caused most commonly by mutations in the gene coding for LDL receptors. This results in increased circulating cholesterol, and clinical consequences of premature stroke, myocardial infarction, etc. FH remains underdiagnosed and thus undertreated, leading to a high health care burden.

Glacial influences on solar radiation in a subarctic sea.

Understanding macroscale processes controlling solar radiation in marine systems will be important in interpreting the potential effects of global change from increasing ultraviolet radiation (UV) and glacial retreat. This study provides the first quantitative assessment of UV in the water column of Prince William Sound, a subarctic, semienclosed sea surrounded by mountains, glaciers, rivers, bays and fjords in south central Alaska. Glacial influences on diffuse attenuation coefficients (Kd) were determined along an approximate 120 km transect running NE (61 degrees 07'43''N, 146 degrees 17'1''W) to SW (60 degrees 27'25''N, 148 degrees 05'27'' W).

Retrospective and current risks of mercury to panthers in the Florida Everglades.

Florida panthers are an endangered species inhabiting south Florida. Hg has been suggested as a causative factor for low populations and some reported panther deaths, but a quantitative assessment of risks has never been performed. This study quantitatively evaluated retrospective (pre-1992) and current (2002) risks of chronic dietary Hg exposures to panthers in the Florida Everglades.
