Meta Analysis
The association of HOTAIR expression with clinicopathological features and prognosis in gastric cancer patients.
A number of studies in gastric carcinoma have demonstrated that cancerous tissues have a significant higher HOTAIR level than that in noncancerous tissues. Overexpression of HOTAIR is associated with the development in gastric cancer. ⋯ There is an association between HOTAIR expression and clinicopathological features and prognosis in gastric cancer patients. High expression of HOTAIR in cancerous tissue could predict poor clinical outcome in gastric cancer, suggesting HOTAIR abundance may serve as a novel candidate biomarker for the clinical outcome in gastric cancers.

The aim of this paper was to investigate the association of circulating osteoprotegerin (OPG) and receptor activator of the nuclear factor kB ligand (RANKL) levels with carotid intima-media thickness (CIMT) in type 2 diabetes mellitus (T2DM). ⋯ The data would support the role of an increased OPG/RANKL ratio as a possible marker of progression of vascular dysfunction in diabetes.

In recent years the efficacy of endovascular venous stenting in idiopathic IIH treatment has been consistently reported, strongly suggesting that sinus stenosis should be viewed as a causative factor rather than a secondary phenomenon. We propose that in subjects carrying one or more collapsible segments of large cerebral venous collectors and exposed to a number of different promoting factors, sinus venous compression and cerebrospinal fluid (CSF) hypertension may influence each other in a circular way, leading to a new relatively stable venous/CSF pressures balance state at higher values. The mechanism relay on self-limiting venous collapse (SVC) feedback-loop between the CSF pressure, that compresses the sinus, and the consequent venous pressure rise, that increases the CSF pressure. ⋯ The SVC model give reason of the high specificity and sensitivity of sinus stenosis as IIH predictor and of the multiplicity of the factors that have been found associated with IIH. Moreover it might explain why, among the sinus stenosis carriers, young and overweight women are at higher risk of developing the disease. Finally, the SVC model fully explain the enigmatic longstanding remissions that can be commonly observed after a single LP with CSF subtraction in IIH with or without papilledema.

Randomized Controlled Trial
Delphinol® standardized maqui berry extract reduces postprandial blood glucose increase in individuals with impaired glucose regulation by novel mechanism of sodium glucose cotransporter inhibition.
The impetus of our study was to investigate the effects of a nutritional supplement Delphinol®, an extract of maqui berries (Aristotelia chilensis) standardised to ≥25% delphinidins and ≥35% total anthocyanins, on postprandial blood glucose and insulin levels and identify the physiologic mechanism involved. ⋯ Our results suggest a potential use of Delphinol® for naturally controlling post-prandial blood glucose owed to inhibition of sodium glucose co-transporter in small intestine.
