Much research has focused on the association between the toxic metabolites of the tactical herbicide Agent Orange and several blood cancers, including systemic amyloid light-chain (AL) amyloidosis. Here we present a rare case of heart failure secondary to cardiac AL amyloidosis as a consequence of Agent Orange exposure. An elderly man was transferred to the intensive care unit for a suspected gastrointestinal bleed and decompensation of congestive heart failure. An echocardiogram suggested restrictive cardiomyopathy, and an abdominal fat pad biopsy confirmed amyloid involvement. The diagnosis of systemic AL amyloidosis was made following a free lambda to free kappa light chain ratio >3:1. Upon discussion with the patient, significant exposure to Agent Orange during deployment was affirmed. Subsequent care was taken over by the Veterans Affairs Medical Center.

Herein, we propose magnetic nanocomposites as a powerful new catalyst for organic pollutant reduction. Polypyrrole (PPy) was synthesized in situ within the semi-interpenetrating alginate (Alg)/gelatin (Ge) network in presence of α-FeO as encapsulating matrix and inorganic filler, respectively. The polymeric matrix can act as bifunctional agent such as a binder and stabilizer to improve nanocatalyst stability while preserving their catalytic/magnetic performances.

species are known to produce various secondary metabolites with polyketide structures, including Monacolins, pigments, and citrinin. This study investigates the effects of 5-azacytidine on M1 and RP2. The dry weight, red, yellow, and orange pigment values, and Monacolin K yield of both strains were measured, and their hyphae observed through electron microscopy.

A series of 2-(4-bromobenzyl) tethered 4-amino aryl/alkyl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-]pyrimidines (7a-7u) were designed, synthesized, characterized and screened against a panel of cancer cell lines. Compound 7a, in particular, emerged as a potent antiproliferative agent against FaDu cells (HTB-43) with an IC value of 1.73 μM.
