Pre-Operative vs. Peri-Operative Nutrition Supplementation in Hepatic Resection for Cancer: A Systematic Review.

Despite improvements in safety of hepatic resection post-operative complications occur in up to a half of patients. A systematic review was undertaken to compare the effect of pre-operative and peri-operative nutritional supplementation on post-operative outcomes in patients undergoing hepatic resection for malignancy. Included studies were identified through a search of PubMed (1966 to November 2016), Embase (1947 to November 2016) and the Cochrane Library (1993 to November 2016).

Cystic Fibrosis: A Novel Pharmacologic Approach to Cystic Fibrosis Transmembrane Regulator Modulation Therapy.

Therapy for cystic fibrosis (CF) has progressed during the past several decades. Much of this progress is because of advances in genetic testing to precisely identify the underlying cause of CF transmembrane regulator (CFTR) dysfunction. However, with more than 1900 mutations that can produce a faulty CFTR, the management of CF can remain a challenge.

Human illness from avian influenza H7N3, British Columbia.

Avian influenza that infects poultry in close proximity to humans is a concern because of its pandemic potential. In 2004, an outbreak of highly pathogenic avian influenza H7N3 occurred in poultry in British Columbia, Canada. Surveillance identified two persons with confirmed avian influenza infection.

Binding sites for L-glutamate in the central nervous system of the rat.

The regional distribution of 2-amino-4-phosphonobutyrate (APB)/chloride-insensitive L-[3H]glutamate binding sites in the rat central nervous system was compared with that of APB/chloride-sensitive and with sodium-dependent binding sites. The distribution of APB-sensitive and APB-insensitive sites was not correlated, but the latter was identical to that of the sodium-dependent sites. The pharmacological specificity of the APB-insensitive sites was not consistent with that of an N-methylaspartate-preferring receptor, and was also different from the specificity determined for the sodium-dependent sites.
