Assessment of total arsenic and arsenic species stability in alga samples and their aqueous extracts [PDF]

Talanta, 2008
In order to achieve reliable information on speciation analysis, it is necessary to assess previously the species stability in the sample to analyse. Furthermore, in those cases where the sample treatment for species extraction is time-consuming, an assessment of the species integrity in the extracts is of paramount importance.

Combined Superior Capsular Reconstruction and Lower Trapezius Transfer Using an Achilles Tendon Allograft Show Better Clinical Outcomes and Lower Graft Tear Rates Versus Isolated Superior Capsular Reconstruction for Chronic Posterosuperior Irreparable Massive Rotator Cuff Tears With Severe Fatty Infiltration in the Infraspinatus

Arthroscopy, EarlyView.
Purpose To compare the surgical outcomes of superior capsular reconstruction (SCR) combined with lower trapezius transfer (LTT) using an Achilles tendon allograft versus isolated SCR for the treatment of posterosuperior irreparable massive rotator cuff tears with severe infraspinatus fatty infiltration (Goutallier grades 3‐4).

Milk intake reduced the prevalence of hypertension by decreasing total arsenic levels in fasting serum in Japanese residents

Ecotoxicology and Environmental Safety
Background: Exposure to arsenic increases the risk of hypertension. Indeed, a high level of arsenic in human serum, a reliable biomarker of arsenic exposure, was shown to be linked to increased prevalence of hypertension among a study of Japanese ...
