A Chelating Resin of EDTA-Type Modified Cross-Linking Polystyrene to Preconcentrate Trace Metals for Seawater Detection.

The determination of trace metals in seawater is an important project of marine environmental monitoring. However, the presence of many alkali metal ions with high concentration, such as sodium ion, seriously interferes with the detection limit and accuracy of atomic absorption spectrometry (AAS, flame/graphite furnace integrated). The conventional chemical methods for the enrichment of trace metals are complex, and low boiling point organic solvents are used.

The physical examination: a survey of patient preferences and expectations during primary care visits.

: Little is known about patient preference regarding the physical exam in non-urgent primary care settings.: To determine the differences between a patient's expectations of the physical exam and the actual components of the physical examination performed during a non-urgent visit.: A total of 452 surveys administered in the waiting room of a VA primary care clinic in West Haven, CT.

Congenital Panfollicular Nevus in a 6-Month-Old Girl.

A 6-month-old girl presented with an irregular nodule on the right lateral neck. The lesion, which superficially resembled a lymphangioma or mastocytoma, had been present since birth but had recently been growing. The patient was referred for surgical resection.

Tailoring the Treatment of Melanoma: Implications for Personalized Medicine.

Oncology has been revolutionized by the ability to selectively inhibit the growth of cancerous cells while ostensibly avoiding the disruption of proteins and pathways necessary for normal cellular function. This paradigm has triggered an explosion of targeted therapies for cancer, creating a burgeoning billion-dollar industry of small molecules and monoclonal antibodies [1]. Largely due to these new treatments, spending on cancer pharmaceuticals has surpassed $100 billion worldwide [2].
