The circulation constitutes a potential source of the beta-amyloid (A beta) protein deposited cerebrally in Alzheimer's disease (AD). Cardiovascular risk factors, including hyperlipidaemia, may be involved in the pathogenesis of AD. Plasma A beta 40 was measured by radioimmunoassay in normal and hyperlipidaemic subjects with the aim of determining if plasma lipid content and/or age correlated with circulating A beta 40 concentration. Plasma A beta 40 levels in hyperlipidaemics were elevated by 20.3% compared to normal subjects. A beta 40 did not correlate with plasma lipids in normal subjects. Age, however, correlated positively with A beta 40 in these individuals and with total cholesterol, low-density lipoprotein (LDL) and triglycerides. No correlations were observed in hyperlipidaemic patients or when the data for the two groups were combined. These data are consistent with ageing, the primary risk factor for AD, but not hyperlipidaemia influencing circulating A beta 40 levels.

Titanium (Ti)-based materials are favored for hard tissue applications, yet their bioinertness limits their success. This study hypothesizes that functionalizing Ti materials with chitosan nano/microspheres and calcitriol (VD) will enhance their bioactivity by improving cellular activities and mineralization. To test this, chitosan particles were applied uniformly onto Ti surfaces using electrophoretic deposition (EPD) at 20 V for 3 minutes.

Two main stages are differentiated in patients with advanced chronic liver disease (ACLD), one compensated (cACLD) with an excellent prognosis, and the other decompensated (dACLD), defined by the appearance of complications (ascites, variceal bleeding and hepatic encephalopathy) and associated with high mortality. Preventing the progression to dACLD might dramatically improve prognosis and reduce the burden of care associated with ACLD. Portal hypertension is a major driver of the transition from cACLD to dACLD, and a portal pressure of ≥10 mmHg defines clinically significant portal hypertension (CSPH) as the threshold from which decompensating events may occur.

Background: Bariatric surgery is the most long-term effective treatment option for severe obesity. The role of gut microbiome (GM) in either the development of obesity or in response to obesity management strategies has been a matter of debate. This study aims to compare the impact of two of the most popular procedures, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (GB), on metabolic syndrome parameters and gut bacterial microbiome and in systemic immuno-inflammatory response.

Renal fibrosis is widely recognized as the ultimate outcome of many chronic kidney diseases. The process of epithelial-mesenchymal transition (EMT) plays a critical role in the progression of fibrosis following renal injury. UHRF1, as a critical epigenetic regulator, may play an essential role in the pathogenesis and progression of renal fibrosis and EMT.
