Grape pomace extract supplementation activates FNDC5/irisin in muscle and promotes white adipose browning in rats fed a high-fat diet.

Irisin is a myokine regulated by peroxisome proliferator-activated receptor gamma co-activator-1α (PGC-1α) in the exercising skeletal muscle and released into the bloodstream after cleavage of FNDC5. Circulating irisin can up-regulate UCP-1 expression in white adipose tissue (WAT) promoting the formation of brown-like adipocytes. The aim of this study was to evaluate if supplementation with a grape pomace extract (GPE) could activate the FNDC5/irisin pathway via PGC-1α in rats fed a high fat diet (HFD).

Vitamin B12 among Vegetarians: Status, Assessment and Supplementation.

Cobalamin is an essential molecule for humans. It acts as a cofactor in one-carbon transfers through methylation and molecular rearrangement. These functions take place in fatty acid, amino acid and nucleic acid metabolic pathways.

Endometrial preparation with Dienogest before hysteroscopic surgery: a systematic review.

Purpose: Hysteroscopic surgery is considered the gold standard for the minimal invasive treatment of many endouterine diseases such as endometrial polyps or submucous myomas. Recently, many studies have evaluated the effect of preoperative administration of a number of drugs to reduce endometrial thickness and achieve important intraoperative advantages. The purpose of this systematic review is to summarize the available evidence about the use of Dienogest, an orally administrable progestin, for endometrial preparation before hysteroscopic surgery.

Type 2 diabetic patients with Graves' disease have more frequent and severe Graves' orbitopathy.

Background And Aims: Due to the worldwide increasing prevalence of diabetes (DM), patients with both diabetes and Graves' disease (GD) have become more frequent. Sporadic reports indicate that Graves' orbitopathy (GO), a GD complication that affects orbital soft tissues, can be severe in DM patients. The relationship between these diseases is not well understood.

Improving the prediction of malignancy in cytologically suspicious thyroid nodules.

Background: Fine needle cytology aspirates (FNA) classified as THY4 are a heterogeneous group suspicious for malignancy [papillary thyroid cancer (PTC)], which is confirmed in 50-80% of cases after surgery.

Aim: To better stratify THY4 FNA specimens for the relative risk of malignancy.

Methods: We retrospectively analyzed 78 thyroid nodules classified as THY4 because of the presence of atypical cells, hypercellular trabeculae and/or intranuclear inclusions (ICI), in the absence of papillae.

Severe Graves' ophthalmopathy after percutaneous ethanol injection in a nontoxic thyroid nodule.

Background: Percutaneous ethanol injection (PEI) is used to treat cystic or mixed benign thyroid nodules. This treatment can result in rare complications, and three cases of Graves' disease (GD) without Graves' ophthalmopathy (GO) have been reported after PEI treatment of toxic thyroid adenomas. Here we present a 55-year-old male patient who developed GD and severe GO after PEI treatment of a mixed cystic-solid, nontoxic thyroid nodule.

Graves' orbitopathy: extraocular muscle/total orbit area ratio is positively related to the Clinical Activity Score.

Background And Objective: Both extraocular muscle (EOM) and orbital fat are involved in Graves' orbitopathy (GO) but their enlargement might occur with a different temporal pattern. Two GO subtypes have been described, one with predominant EOM enlargement and the other with prevalent fat tissue involvement. We longitudinally investigated the EOM in patients with GO and their relationship with clinical activity.
