Although only a few species of account for the major truffle sales volume, many species that are not considered delicacies are finding their way to the market, especially in regions where the traditionally appreciated ones do not occur. This is the case for whitish truffles. Specimens of whitish truffles were collected in pecan () orchards in Uruguay in October 2021.

Therapeutic strategies in NAFLD include lifestyle changes mainly related to dietary interventions and use of drugs or nutritional components that could improve plasma lipid profiles and insulin sensitivity and decrease the local inflammatory response. In this study, we tested the effects of monacolin K, an inhibitor of HMCoA reductase.

Methods: This was a cross-sectional study, based on errors reported on the National Immunization Program Information System between 2015 and 2019. A descriptive analysis and calculation of the incidence for the state's health macro-regions were performed.
Background And Aims: Cardiac structural and functional changes have been demonstrated in patients with non-alcoholic fatty liver disease (NAFLD). Because of the frequent association of NAFLD with hypertension, we aimed to examine the relationship of liver steatosis with left ventricular (LV) changes in patients with hypertension.
Materials And Methods: In a cross-sectional study, we included 360 untreated, essential hypertensive patients who were free of major cardiovascular and renal complications.
is a pioneer ectomycorrhizal fungus with facultative saprophytic capacities. Here, we sequenced the genome of strain Sb_GMNB300, which is estimated at 51.6 Mb in size with 872 assembled contigs accounting for 12,597 predicted coding genes.

However, the protective role of the sustained virologic response (SVR) achieved by second- and third-generation DAAs against the onset of hepatocellular carcinoma (HCC) and mortality is less well established.
Aim: To examine the occurrence of HCC or death from any cause in a retrospective-prospective study of patients treated with DAAs.
Chronic HCV liver infection is considered one of the main causes of liver cirrhosis and hepatocellular carcinoma (HCC). For a selected group of patients, orthotopic liver transplantation (OLTx) is the most effective option to cure both liver diseases. After liver transplantation, patients may be at risk of viral infection reactivation and HCC recurrence.

Few data are available on the hygienic condition and the presence of foodborne pathogens in such products. Therefore, the current study aimed to evaluate the safety and hygienic characteristics of both ready-to-eat and ready-to-cook, pre-cut sliced mushrooms obtained from a local Italian market.

In the southern USA, truffles (Tuber spp.) sometimes fruit prolifically in cultivated pecan orchards and regularly associate with pecan roots as ectomycorrhizae (ECMs).

Background: Nonalcoholic fatty liver disease (NAFLD) is strongly associated to oxidative stress, metabolic syndrome, and cardiovascular risk. Hepatocytes overloaded with fatty acids (FA) could generate substances that interfere with endothelial function, providing a potential explanation for this association. We have investigated the response of cultured human hepatoblastoma cells (Hep-G2) that were exposed to FA by measuring markers of oxidative stress and thrombosis and expression of the insulin receptor.

However, interferon-α may induce severe depression. It has been suggested that interferon-α is able to modify cytochrome P450 (CYP) 1A2 and 2D6 activity.

Some antihypertensive drugs affect oxidative stress and endothelial function and might counteract the effects of alcohol at the cellular level. The aim of this study was to investigate in vitro the effects of three different types of antihypertensive agents on alcohol-induced endothelial responses and oxidative stress.
View Article and Find Full Text PDFBackground: Epidemiological investigations have demonstrated a close association between heavy alcohol consumption and hypertension. The mechanisms of this association, however, remain elusive. We studied the effects of alcohol withdrawal on blood pressure, hormonal parameters, and circulating markers of endothelial activity.
View Article and Find Full Text PDFContext: The recently discovered hormone resistin is linked to the development of insulin resistance, but direct evidence of resistin levels in humans with nonalcoholic fatty liver disease (NAFLD) is lacking.
Methods: We conducted this study to assess the relationship between serum resistin and NAFLD. We measured serum resistin and biochemical, hormonal, and histological correlates in 28 NAFLD patients, 33 controls, and 30 obese patients [body mass index (BMI), >30 kg/m2] without NAFLD.
Background: Although heavy alcohol drinkers are at an increased risk of developing cardiovascular events, moderate alcohol intake is associated with reduced incidence of cardiovascular death. This paradox might reflect a dose-related effect of different alcohol intakes on endothelial function and this, in turn, might depend on changes in oxidative stress.
Methods: We tested the effects of alcohol withdrawal in heavy alcohol consumers and compared the plasma levels of endothelin-1, nitric oxide, plasminogen activator inhibitor-1, von Willebrand factor, malondialdehyde, and intracellular glutathione with those of alcoholics that did not modify their alcohol intake and teetotalers.
Objectives: Nonalcoholic fatty liver disease (NAFLD) is a major cause of liver-related morbidity and is frequently associated with obesity and metabolic syndrome. The recently discovered hormone adiponectin is produced by adipose tissue, and low plasma adiponectin is considered a key factor in the development of the insulin resistance underlying metabolic syndrome. Animal studies suggest that adiponectin may protect against non-alcoholic steatohepatitis, but direct evidence in humans is lacking.

Because thyrotropin (TSH) regulates many thyroid-specific functions and cell proliferation, we investigated whether TSH can influence such mechanisms. To induce apoptosis we used UV-C radiation.

Since endothelial dysfunction occurs at early stages of disease, it may reflect pathophysiological changes that are responsible for alterations in vascular structure, growth and modifications of adhesivity to platelets and leukocytes, leading to atherosclerosis and thrombosis. Predisposing factors of vascular diseases, such as diabetes, are also associated with endothelial dysfunction.
