AI Article Synopsis
Article Abstract
Serum zinc levels were assayed in patients with AIDS and related syndromes, using spectrophotometry and atomic absorption. Statistical data have shown that serum zinc levels, in addition to being significantly lower (p less than 0.001) among different groups and controls, decrease progressively with the worsening of the clinical and immunological picture from LAS to AIDS. Serum zinc levels in patients with AIDS and ARC have, moreover, been demonstrated to be related (r = 0.8240; p less than 0.001) to the lymphocyte subset CD4 helper-induced. These results suggest that serum zinc determination and possibly zinc therapy might be reasonably considered in the management of patients with symptoms of HIV infection.

Hepatopulmonary syndrome (HPS) is a severe lung injury caused by chronic liver disease, with limited understanding of the disease pathology. Exosomes are important mediators of intercellular communication that modulates various cellular functions by transferring a variety of intracellular components to target cells. Our recent studies have indicated that a new long noncoding RNA (lncRNA), PICALM-AU1, is mainly expressed in cholangiocytes, and is dramatically induced in the liver during HPS.

The objective of the present study was to assess serum and cancerous tissue biometal levels in colorectal cancer (CRC) patients, and its relation to disease severity. A total of 90 CRC patients and 97 controls were involved in the present study. The level of biometals in blood serum and colon tissues (only in CRC cases) was evaluated by inductively-coupled plasma mass-spectrometry.

Background: Conflicting findings exist regarding the association between maternal serum zinc and neonatal birth weight. This study aimed to explore the association between maternal serum zinc and birth weight, and whether this association was modified by neonatal SOD2 polymorphism and promoter methylation.
Methods: We recruited 464 mother-newborn pairs at Houzhai Center Hospital from January 2010 to January 2012.
