A case of adrenal cortical carcinoma arising from a regularly monitored sub-centimetre adrenal incidentaloma.

Summary: Approximately 80% of adrenal incidentalomas are benign, and development into adrenal cortical cancer is extremely rare. This is a major reason behind clinical guidelines recommending surveillance of incidentalomas for a relatively short duration of up to 5 years. Surveillance of lesions less than 1 cm is not routinely recommended.

Circulating soluble CD163 as a potential biomarker of diabetes complications.

Aims: To investigate whether soluble CD163 (sCD163) is altered in those with diabetes and various subtypes of complications and non-alcoholic fatty liver disease (NAFLD), and whether it can assess disease complications and severity in people with diabetes.

Methods: Adults with diabetes (n = 101) were recruited and assessed for the presence of any complications (D). Liver steatosis presence was determined by ultrasound and liver stiffness measurement (LSM) by transient elastography.

Targeting CCN2 protects against progressive non-alcoholic steatohepatitis in a preclinical model induced by high-fat feeding and type 2 diabetes.

Type 2 diabetes is an independent risk factor for non-alcoholic steatohepatitis (NASH) progression and its mediators have not been resolved. In this study, a pathogenic role of cellular communication network factor 2 (CCN2) protein in NASH pathology, was investigated in an established preclinical NASH model. Male wild type C57BL/6 mice received either Chow or high fat diet (HFD) for 26 weeks, with some mice in each group randomly selected to receive low dose streptozotocin (STZ: 3 i.

Beneficial effects of the synthetic antioxidant tert-butyl bisphenol on the hepatic microcirculation in a rat model of diabetes mellitus.

Diabetes mellitus is associated with oxidative injury to the vasculature. Here, the link between oxidative stress and ultrastructural changes in the hepatic microcirculation was investigated as well as the effects of a synthetic antioxidant, tert-butyl bisphenol (tBP). The study focused on the impact of experimental diabetes on liver sinusoidal endothelial cell (LSEC) fenestrations, which are pores in the liver endothelium that facilitate substrate transfer between blood and hepatocytes.

The acute-phase protein serum amyloid A induces endothelial dysfunction that is inhibited by high-density lipoprotein.

The acute-phase protein serum amyloid A (SAA) is elevated during inflammation and may be deposited in atheroma where it promotes atherosclerosis. We investigated the proatherogenic effects of SAA on the vascular endothelium and their regulation by high-density lipoprotein (HDL). Exposure of human aortic endothelial cells (HAEC) to SAA (0.

Phenolic antioxidants tert-butyl-bisphenol and vitamin E decrease oxidative stress and enhance vascular function in an animal model of rhabdomyolysis yet do not improve acute renal dysfunction.

Rhabdomyolysis (RM) caused by severe burn releases extracellular myoglobin (Mb) that accumulates in the kidney. Extracellular Mb is a pro-oxidant. This study tested whether supplementation with tert-butyl-bisphenol (BP) or vitamin E (Vit E, as α-tocopherol) at 0.

The synthetic polyphenol tert-butyl-bisphenol inhibits myoglobin-induced dysfunction in cultured kidney epithelial cells.

Abstract Rhabdomyolysis caused by severe burn releases extracellular myoglobin (Mb) that accumulates in the kidney and urine (maximum [Mb] approximately 50 microM) (termed myoglobinuria). Extracellular Mb can be a pro-oxidant. This study cultured Madin-Darby-canine-kidney-Type-II (MDCK II) cells in the presence of Mb and tested whether supplementation with a synthetic tert-butyl-polyphenol (tert-butyl-bisphenol; t-BP) protects these renal cells from dysfunction.

Multiple protective activities of neuroglobin in cultured neuronal cells exposed to hypoxia re-oxygenation injury.

Oxidative stress is associated with the pathology of acute and chronic neurodegenerative disease. We have cloned a human neuroglobin (Nb) construct and over-expressed this protein in cultured human neuronal cells to assess whether Nb ameliorates the cellular response to experimental hypoxia-reoxygenation (H/R) injury. Parental cells transfected with a blank (pDEST40) vector responded to H/R injury with a significant decrease in cellular ATP at 5 and 24 h after insult.

Myoglobin induces oxidative stress and decreases endocytosis and monolayer permissiveness in cultured kidney epithelial cells without affecting viability.

Background: Muscle degradation caused by severe burn releases myoglobin (Mb), which accumulates in the kidney (termed myoglobinuria). Mb is a pro-oxidant.

Aim: To demonstrate that Mb promotes oxidative stress and dysfunction in cultured Madin-Darby canine kidney type II (MDCK II) cells.
